ABSTRACT

BACKGROUND Malignant mesotheliomas are rare, yet highly malignant tumors. Mesotheliomas are tumors that develop from mesothelial surfaces, with the pleura being the most common, followed by the peritoneum. The diagnosis of malignant peritoneal mesothelioma (MPM) is usually established when the disease is advanced, owing to the nonspecific clinical appearance and abdominal symptoms. Initially, MPM was treated with palliative systemic chemotherapy, with or without palliative surgery. However, cytoreductive surgery (CRS) combined with bidirectional intraoperative chemotherapy (BDIC) has recently emerged as a treatment option for MPM. BDIC creates a bidirectional chemotherapy gradient in the peritoneal tumor cells through the simultaneous use of intraperitoneal and intravenous chemotherapy. CRS, combined with BDIC (CRS-BDIC), allows the complete elimination of residual tiny tumor cells after complete removal of the visible tumor nodules. CASE REPORT Herein, we present a case of a 51-year-old woman with MPM and chronic kidney disease (CKD) stage 3b. Her treatment consisted of neoadjuvant chemotherapy and immunotherapy, followed by CRS-BDIC using intraperitoneal cisplatin and doxorubicin, and intravenous ifosfamide. The surgery was successful, with no immediate complications or decline in the patient's kidney function. On follow up 2 months later, the patient denies suffering any chemotherapy-related adverse effects, and her kidney profile remains stable. CONCLUSIONS In conclusion, nephrotoxicity, a known adverse effect of cisplatin and ifosfamide, might not be a contraindication for the use of these potentially nephrotoxic drugs in CRS-BDIC in patients with renal impairment.

ABSTRACT

BACKGROUND: The therapy of high-risk soft tissue sarcomas (STS) remains an interdisciplinary challenge. Regional hyperthermia (RHT) sparked interest as it has been shown to improve overall survival when added to perioperative chemotherapy (CTX). However, questions arise on how RHT should be optimally integrated into current multi-modal therapies. MATERIALS AND METHODS: We performed a systematic literature review according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Studies written in English and focused mainly on radiative RHT and superficial hyperthermia were evaluated and included. Studies including patients below the age of 18, with metastatic disease or review articles, were excluded. RESULTS: We identified 15 clinical reports from 1990 until July 2022. Three articles combined RHT + CTX, and twelve focused on combined RHT + radiotherapy (RT) or neoadjuvant chemoradiotherapy (CRT). Most treatments were based on invasive thermometry, and less on magnetic resonance imaging (MRI)-based, noninvasive thermometry for STS of the extremities. Perioperative chemotherapy was used for the combination of RHT and CTX, mostly Ifosfamide-based. The effectiveness of RT appeared to be increased by RHT, especially with two RHT sessions/week. The trimodal simultaneous approach of neoadjuvant RHT and CRT was also feasible. No significant toxicity of RHT was reported. CONCLUSIONS: The gathered data strengthen the beneficial role of RHT in the multimodal setting. Further expert consensus and clinical trials are required to determine the optimal integration of RHT in treating STS.

ABSTRACT

BACKGROUND Malignant peritoneal mesothelioma (MPM) is an aggressive neoplasm with a poor prognosis. Bidirectional intraoperative chemotherapy (BDIC) using concurrent intraperitoneal and intravenous chemotherapy in combination with cytoreductive surgery (CRS) is an emerging treatment option for selected cases of MPM. It is a locoregional treatment that involves intraoperative chemoperfusion of heated chemotherapy. The administration of systemic along with intraperitoneal chemotherapy allows for a bidirectional chemotherapy gradient in peritoneal tumor cells. The aim of this treatment is eradication of microscopic residual cancer cells after major removal of macroscopic tumor nodules. To date, there is no consensus on the chemotherapeutic regimen that can be used in BDIC to manage MPM in patients with severe renal impairment. Administering intravenous ifosfamide with hyperthermic intraperitoneal cisplatin and doxorubicin is a promising regimen in treating peritoneal mesothelioma. Nephrotoxicity is a dose-limiting adverse effect of cisplatin and ifosfamide. Therefore, dose adjustment is required in patients with renal impairment. CASE REPORT In this report, we describe a 46-year-old female patient with recurrent MPM and severe renal impairment. Her treatment was managed with hyperthermic intraperitoneal cisplatin and doxorubicin along with intravenous ifosfamide following CRS. The cisplatin dose was reduced to 50% and the ifosfamide dose was reduced by 25%. The patient tolerated the procedure well, without deterioration in her renal function. At her 9-month follow-up, she did not report experiencing chemotherapy-related adverse effects, and her kidney function remained stable. CONCLUSIONS Severe renal impairment might not be a contraindication to using potentially nephrotoxic chemotherapeutic agents in CRS-BDIC.

ABSTRACT

Background Sorafenib is a potent targeted-therapy that blockades angiogenesis and has demonstrated activity against some sarcoma subtypes. Preclinical studies suggested that treatment with sorafenib plus cytotoxic agents could result in additive efficacy. Methods Patients with advanced soft tissue sarcoma, with or without anthracycline pretreatment were included. Patients received oral sorafenib 400 mg twice daily starting on Day +2, ifosfamide 2.0 g/m2 iv infusion lasting 4 h on days 1, 2 and 3 with concurrent mesna 400 mg/m2 every three weeks until disease progression or unacceptable toxicity or up to a maximum of 6 cycles of ifosfamide (sorafenib could be continued until progressive disease or unacceptable toxicity). Primary objective was progression-free rate (PFR) at 3 and 6 months; secondary objectives were overall response rate (ORR), Progression-free survival (PFS), Overall survival (OS) and safety. This article reports the phase II part of a phase I/II clinical trial. Results Thirty-five patients were enrolled. PFR at 3 and 6 months was 66% (95% CI 48-81) and 37% (95% CI 22-55). Six patients (17%) achieved partial response and 17 (49%) stable disease. Median PFS was 4.8 months (CI 95% 1.94-6.36) and overall survival 16.2 months (95% CI 8.75-NA). Conclusion Treatment with sorafenib plus ifosfamide achieved a significant clinical benefit with an acceptable safety profile in patients with advanced soft tissue sarcoma resistant to anthracyclines, which warrants a more detailed study in randomized clinical trials.

ABSTRACT

BACKGROUND The aim of this study was to compare nutrition-related adverse events and clinical outcomes of ifosfamide, carboplatin, and etoposide regimen (ICE therapy) and ranimustine, carboplatin, etoposide, and cyclophosphamide regimen (MCEC therapy) instituted as pretreatment for autologous peripheral blood stem cell transplantation. MATERIAL AND METHODS We enrolled patients who underwent autologous peripheral blood stem cell transplantation between 2007 and 2012. Outcomes were compared between ICE therapy (n=14) and MCEC therapy (n=14) in relation to nutrient balance, engraftment day, and length of hospital stay. In both groups, we compared the timing of nutrition-related adverse events with oral caloric intake, analyzed the correlation between length of hospital stay and duration of parenteral nutrition, and investigated the association between oral caloric intake and the proportion of parenteral nutrition energy in total calorie supply. Five-year survival was compared between the groups. RESULTS Compared with the MCEC group, the ICE group showed significant improvement in oral caloric intake, length of hospital stay, and timing of nutrition-related adverse events and oral calorie intake, but a delay in engraftment. Both groups showed a correlation between duration of parenteral nutrition and length of hospital stay (P=0.0001) and between oral caloric intake (P=0.0017) and parenteral nutrition energy sufficiency rate (r=-0.73, P=0.003; r=-0.76, P=0.002). Five-year survival was not significantly different between the groups (P=0.1355). CONCLUSIONS Our findings suggest that compared with MCEC therapy, ICE therapy improves nutrition-related adverse events and reduces hospital stay, conserving medical resources, with no significant improvement in long-term survival. The nutritional pathway may serve as a tool for objective evaluation of pretreatment for autologous peripheral blood stem cell transplantation.

ABSTRACT

INTRODUCCIÓN: El análisis de impacto presupuestal (AIP) de los medicamentos quimioterapéuticos para el tratamiento de cáncer en Colombia, se desarrolló en el marco del mecanismo técnico científico para la ampliación progresiva del Plan de Beneficios en Salud con cargo a la UPC (PBSUPC) y la definición de la lista de exclusiones, establecido en el artículo 15 de la Ley 1751 de 2015. La quimioterapia tiene un gran impacto en el tratamiento oncológico, la cual es indispensable por su valor terapéutico en varios tipos de cáncer. Esta tecnología puede ser usada sola o junto con otros tratamientos, tales como la cirugía o la radioterapia. La quimioterapia engloba a una gran variedad de fármacos y su objetivo es destruir las células tumorales con el fin de lograr la reducción de la enfermedad, los medicamentos empleados en este tipo de tratamiento se les denomina fármacos antineoplásicos. Cada tipo de tumor canceroso tiene una determinada sensibilidad a estos medicamentos, por lo tanto, es frecuente que el mismo fármaco se pueda emplear en el tratamiento de distintos tumores, variando las dosis o asociándolo a otros fármacos distintos. La quimioterapia puede ser administrada con fines curativos o para aliviar los síntomas y prolongar la supervivencia. La forma de administración de la quimioterapia es por ciclos y esto se logra alternando los periodos de tratamiento con periodos de descanso. Un ciclo es, por lo tanto, el periodo de administración del tratamiento y el de descanso hasta la siguiente administración. El objetivo de este análisis de impacto presupuestal (AIP) es estimar el esfuerzo financiero necesario para la adopción de la quimioterapia en el tratamiento de pacientes con cáncer en Colombia, en un horizonte temporal de tres años. Este documento está conformado por cuatro secciones: en la primera se identifican las tecnologías a evaluar, en la segunda sección se especifica la perspectiva, horizonte temporal y la población sobre la cual se realizó el AIP; en la sección tres se detallan los costos utilizados en el modelo, además de los escenarios planteados por los investigadores; por último, en la sección cuatro se exponen los resultados en los diferentes escenarios planteados Este documento describe la metodología desarrollada para realizar el análisis de impacto presupuestal de 21 tecnologías para el manejo quimioterapéutico del cáncer en Colombia Este informe, sigue los lineamientos propuestos en el Manual para la Elaboración de Análisis de Impacto Presupuestal y en Manual de Participación y Deliberación publicados por IETS. Insumos y método: Esta sección presenta los supuestos, parámetros y métodos utilizados para el modelo de estimación del impacto presupuestal describiendo la siguiente información: Perspectiva: La perspectiva de este AIP es la del tercer pagador el cual en nuestro contexto es el Sistema General de Seguridad Social en Salud (SGSSS). Horizonte temporal: El horizonte temporal de este AIP en el caso base corresponde a un año. Adicionalmente se reportan las estimaciones del impacto presupuestal para los años 2 y 3, bajo el supuesto de inclusión en el PBS en el año 1. Población total: Para el desarrollo de este AIP se parte de la población general afiliada al SGSSS colombiano sin distinción de sexo o edad. ESCENARIOS: Se consideró para la formulación de los escenarios de adopción de las tecnologías evaluadas los siguientes aspectos: 1. Los medicamentos evaluados no son alternativas terapéuticas para las patologías observadas, estas tecnologías sanitarias hacen parte de los protocolos de tratamiento con evidencia científica suficiente que garantizan su efectividad y seguridad clínica y que actualmente se encuentran en las opciones de tratamiento utilizados en la práctica clínica colombiana. 2. Al ser esquemas de tratamiento que hacen parte de protocolos estandarizados de aplicación, sí alguno de los medicamentos es sujeto de recobros ante ADRES, este trámite puede generar barreras de acceso al tratamiento hasta que se efectué la respectiva aprobación. Por lo tanto, no hay certeza de la efectividad clínica si los esquemas de tratamiento son suministrados de forma parcial o incompleta. 3. La elección del esquema de tratamiento obedece a criterios clínicos y a las características evaluadas en el paciente, no se espera una sustitución entre los diferentes esquemas sí se realiza un cambio en el mecanismo de financiamiento. 4. La adopción de las tecnologías evaluadas en este AIP no se espera que se modifiquen de manera importante, debido a que estas tecnologías hacen parte integral de los esquemas de tratamiento y su incorporación en la práctica clínica habitual en el contexto internacional y nacional, data de aproximadamente 10 a 5 años. Tambieén son parte de las opciones de primera línea de tratamiento para estadios tempranos, avanzados y localmente avanzados del paciente diagnosticado con câncer. De acuerdo a las anteriores consideraciones, al incorporar los medicamentos evaluados al PBS con cargo a la UPC, se espera la misma composición del mercado con la adopción de los nuevos medicamentos en el 100% de los tratamientos esperados en la siguiente anualidad. Los resultados esperados en el sistema de salud, en este cambio de financiamiento, se esperan obtener en dos puntos: a) En una mejor oportunidad de acceso a los esquemas de tratamiento en el SGSSS (25). b) En una mejora en la cobertura efectiva de los tratamientos de quimioterapia en pacientes con diagnóstico de cáncer. RESULTADOS: Se muestra el resultado consolidado para las ventiun tecnologías objeto del Análisis de Impacto Presupuestal. La tecnología que genera un mayor impacto es Oxaliplatino, con un valor por persona de $2.363.250,76 usada en 3170 pacientes, para un total de $7.491.504.923,90. El Megestrol es la tecnología con menor impacto, con un costo por persona de $ 383.791,06 y siendo usada en 34 pacientes, tiene un valor total de $ 13.048.896,00. La tretinoina es la tecnología más económica por paciente, con un valor de $ 97.996,50, es usada en 242 personas para un total de $ 23.715.153,00. DISCUSIÓN: En la práctica actual existe un volumen amplio de recobros en el caso de estos medicamentos por usos UNIRS. En algunos casos, los cambios en el mercado farmacéutico, ya sea por el retiro de medicamentos o la llegada de ellos, hace que se modifique indicaciones ya existentes en los registros y que pueden llegar a impactar estos. usos, por ejemplo aquellos casos en los que existe la indicación antineplásico y se cambian por indicaciones especificas, que pueden no considerar condiciones de salud de baja incidencia. Como se ha caracterizado con anterioridad, el mercado de tecnologías sanitarias que se encuentran incluidas al plan de beneficios en salud con cargo a la UPC difiere sustancialmente al mercado de tecnologías sanitarias aún no financiadas por dicho mecanismo. La existencia de las Empresas Administradoras de Planes de Beneficios (EAPB) presume la existencia de un actor que al maximizar su beneficio, es un buen negociador que en cumplimiento de los principios del SGSSS, llega a un precio de equilibrio que maximiza el beneficio social. En cambio, los medicamentos que son sujetos a recobros al ADRES presume un precio fuera de aquel nivel en donde se maximiza al beneficio social, en la medida que no hay una función clara de monopsonio que coteje y negocie un precio de adquisición. En algunos casos puede llegar asumir sobrecostos que las EAPB al ser intermediarias, no tienen incentivos para efectuar un adecuado control. Con el objetivo de estimar el resultado de la incorporación de estos medicamentos al PBS con cargo a la UPC, se asumieron dos escenarios en los cuales la población objetivo del AIP se consideró constante y se asumieron los siguientes supuestos: En el primer escenario se asume que los precios observados en recobros serán el promedio de todas las transacciones de compra en la siguiente anualidad. En el segundo escenario los precios promedio de adquisición de los medicamentos evaluados, corresponden al promedio observado en SISMED como predictor de los precios de equilibrio que pueden generar las EAPB como ente negociador. Se asume que, en promedio, las EAPB son negociadores eficientes que se acercan a un precio de equilibrio que maximiza el bienestar social. Se asume que la población objetivo corresponde al total de posibles pacientes que requieren las tecnologías sanitarias en evaluación, sin que exista demanda insatisfecha para estos esquemas de tratamiento. Para su cálculo, como se presenta en la tabla 09 de los servicios prestados durante el año 2015 y recobrados al FOSYGA en los años 2015 y 2016, se calculó un valor per-cápita de acuerdo con el identificador (cedula de ciudadanía anonimizada) registrado en cada recobro. Luego, este valor es indexado a precios 2016 con el IPC reportado por el DANE a diciembre 31 del año 2015. Este valor será el comparador del precio calculado para cada uno de los medicamentos a partir de SISMED 2016.

ABSTRACT

INTRODUCTION: Treatment options for patients with platinum refractory metastatic germ cell tumours (GCT) relapsing after high-dose chemotherapy and autologous stem cell transplantation are limited and survival is poor. Antibodies directed against programmed cell death protein-1 (PD-1) and programmed cell death ligand-1 (PD-L1) are currently assessed within clinical trials. We present updated data on our experience with checkpoint inhibitors as a compassionate use off-label treatment attempt for highly-pretreated patients with GCT and provide an overview of the current literature on PD-L1 expression in this rare tumour entity. PATIENTS AND METHODS: We analysed all patients with platinum refractory GCT treated with checkpoint inhibitors at our institutions between 2015 and 2017. Data were retrieved retrospectively from the patient charts. RESULTS: Seven patients were treated with nivolumab or pembrolizumab. Four patients received single-dose treatment and died shortly afterwards due to tumour progression; the remaining three patients received treatment for at least 6 months. No significant treatment toxicity was observed. Long-term tumour response was achieved in two of the three patients, both of them highly positive for PD-L1 staining. INTERPRETATION: We consider checkpoint inhibition to be efficient in carefully selected patients with platinum refractory GCT. However, predictive markers associated with tumour response are not yet known and larger prospective clinical trials are warranted.

ABSTRACT

BACKGROUND: Desmoplastic Small Round Cell Tumor (DSRCT) is a rare disease affecting predominantly children and young adults and for which the benefit of hyperthermic intraperitoneal chemotherapy (HIPEC) after complete cytoreductive surgery (CCRS) remains unknown. METHODS: To identify patients with DSRCT without extraperitoneal metastases (EPM) who underwent CCRS between 1991 and 2015, a retrospective nation-wide survey was conducted by crossing the prospective and retrospective databases of the French Network for Rare Peritoneal Malignancies, French Reference Network in Sarcoma Pathology, French Sarcoma Clinical Network and French Pediatric Cancer Society. RESULTS: Among the 107 patients with DSRCT, 48 had no EPM and underwent CCRS. The median peritoneal cancer index (PCI) was 9 (range: 2-27). Among these 48 patients, 38 (79%) had pre- and/or postoperative chemotherapy and 23 (48%) postoperative whole abdominopelvic radiotherapy (WAP-RT). Intraperitoneal chemotherapy was administered to 11 patients (23%): two received early postoperative intraperitoneal chemotherapy (EPIC) and nine HIPEC. After a median follow-up of 30 months, the median overall survival (OS) of the entire cohort was 42 months. The 2-y and 5-y OS were 72% and 19%. The 2-y and 5-y disease-free survival (DFS) were 30% and 12%. WAP-RT was the only variable associated with longer peritoneal recurrence-free survival and DFS after CCRS. The influence of HIPEC/EPIC on OS and DFS was not statistically conclusive. CONCLUSION: The benefit of HIPEC is still unknown and should be evaluated in a prospective trial. The value of postoperative WAP-RT seems to be confirmed.

ABSTRACT

INTRODUCCIÓN: El presente informe expone la evaluación de tecnología sobre la eficacia y seguridad de mifamurtida, para el tratamiento de pacientes con osteosarcoma (OS) osteoblástico no metastásico sin tratamiento sistémico previo, en el contexto de neoadyuvancia com quimioterapia MAPI (metotrexato, doxorrubicina, cisplatino e ifosfamida). El osteosarcoma (OS) es un tumor maligno primario del esqueleto y la neoplasia primaria más común del hueso en niños y adultos jóvenes. Representa aproximadamente el 20% de todos los tumores óseos primarios malignos y el 0.2% de todos los tumores malignos. Su curva de distribución en cuanto a la edad es bimodal, con un primer pico en la adolescencia y otro después de los 65 años. La adición de quimioterapia agresiva adyuvante o neoadyuvante a la cirugía há mejorado considerablemente el pronóstico de los pacientes con enfermedad localizada, incrementando la tasa de curación de pacientes con OS en las extremidades y sin enfermedad metastásica evidente de 10-15% a 50-70%. OBJETIVO: El presente dictamen preliminar expone la evaluación de la tecnología sanitaria de la eficacia y seguridad de mifamurtida, para el tratamiento de pacientes com osteosarcoma (OS) osteoblástico no metastásico sin tratamiento sistémico previo, en el contexto de neoadyuvancia con quimioterapia MAPI (metotrexato, doxorrubicina, cisplatino e ifosfamida). TECNOLOGIA SANITARIA DE INTERES: La mifamurtida (Mepact, Takeda) es un compuesto químico biológicamente activo con actividad inmunomoduladora, clasificándose como un adyuvante biológico y perteneciente al grupo farmacoterapéutico de los inmunoestimulantes (36,37) . El compuesto es un derivado totalmente sintético del muramil dipéptido (MDP), el estimulante inmunológico natural más pequeño de las paredes celulares de micobacterias (37) . Al igual que la MDP, la mifamurtida es reconocida por el receptor de reconocimiento de patrones NOD2, localizado en varios tipos de glóbulos blancos, principalmente monocitos y macrófagos. De tal manera, mifamurtida simula una infección bacteriana, resultando en una activación de los macrófagos y un incremento en la producción de TNF-alfa, interleuquina 1, 6, 8 y 12, y moléculas de adhesión (e.g., ICAM-1 y LFA-1). METODOLOGÍA: Se llevó a cabo una búsqueda sistemática de la literatura con respecto a la eficacia y seguridad del uso de mifamurtida para el tratamiento de pacientes con osteosarcoma osteoblástico no metastásico sin tratamiento sistémico previo, en el contexto de neoadyuvancia con quimioterapia MAPI (metotrexato, doxorrubicina, cisplatino e ifosfamida). La búsqueda se realizó utilizando las bases de datos: National Library of Medicine (PubMed, 09/2017), Web of Science (WoS, 09/2017), y Centre for Reviews and Dissemination (CRD, 09/2017). Adicionalmente, se amplió la búsqueda revisando la evidencia generada por grupos internacionales que realizan revisiones sistemáticas (RS), evaluaciones de tecnologías sanitarias (ETS) y guías de práctica clínica (GPC), tales como The Cochrane Library (09/2017), The National Institute of Health and Care Excellence (NICE, 08/2017) del Reino Unido, The National Guidelines of Clearinghouse (NGC, 08/2017) de los Estados Unidos, The Scottish Intercollegiate Guidelines Network (SIGN, 08/2017) de Escocia, Australian Clinical Practice Guidelines (08/2017), The Royal Children's Hospital Melbourne Practice Guidelines de Australia (08/2017), CMA Infobase de la Canadian Medical Association (08/2017), American College of Physicians Clinical Practice Guidelines and Recommendations (08/2017) de los Estados Unidos, Guidelines International Network (GIN, 08/2017), New Zealand Guidelines Group (NZGG, 08/2017) de Nueva Zelanda, Guía Salud de España (08/2017, 08/2017), y el Centro Nacional de Excelencia Tecnológica en Salud (CENETEC) de México. Esta búsqueda se completo revisando publicaciones de grupos dedicados a la educación, investigación y mejora de la práctica clínica oncológica dentro de América y Europa, como The National Comprehensive Cancer Network (NCCN, 09/2017) de los Estados Unidos, y The European Society for Medical Oncology (ESMO, 08/2017). Por último, se completó la búsqueda ingresando a la página web www.clinicaltrials.gov, para así poder identificar ensayos clínicos en elaboración o que no hayan sido publicados aún, y así disminuir el riesgo de sesgo de publicación. RESULTADOS: se llevó a cabo una búsqueda bibliográfica y de evidencia científica hasta setiembre de 2017 relacionada al uso de mifamurtida en el tratamiento de pacientes con osteosarcoma (OS) osteoblástico no metastásico sin tratamiento sistémico previo, en el contexto de neoadyuvancia con quimioterapia MAPI (metotrexato, doxorrubicina, cisplatino e ifosfamida). Según las guías consultadas para pacientes con OS no metastásico resecable, referentes al uso de mifamurtida como parte del régimen quimioterapéutico MAPI neoadyuvante (pre-operatorio), no existen recomendaciones generales, unicamente algunas hacen mención al uso de mifamurtida en un contexto de adyuvancia (post-operatorio). El único ensayo clínico que evalúa el uso de mifamurtida dentro del régimen quimioterapéutico MAPI, lo hace en un contexto adyuvante, el cual reporta que no hubo una mejora estadísticamente significativa en relación a la sobreviva libre de eventos (HR 0.78, IC 95%: 0.54 ­ 1.2; p=0.22). Por otro lado, si bien se observó una aparente mejora en relación a la sobrevida global (HR 0.71; IC 95%, 0.52 ­ 0.96, valor p no reportado), es de notar que el límite superior del intervalo de confianza es marginal con respecto al valor nulo de no significancia estadística y que el valor p no ha sido reportado. Asimismo, estos resultados son invalidados por i) interacción observada entre mifamurtida y quimioterapia, afectando el análisis marginal del ensayo, ii) falta de poder estadístico para comparar individualmente los cuatro regímenes quimioterapéuticos evaluados, y iii) aparente falta de poder estadístico para evaluar el efecto de mifamurtida a los regímenes quimioterapéuticos sobre la sobrevida global. Actualmente, no se ha identificado ningún estudio publicado o en proceso dirigido a evaluar los efectos de la mifamurtida neoadyuvante en población con diagnóstico de OS no metastásico. Por lo tanto, no existe evidencia respecto a la eficacia y seguridad de mifamurtida en un contexto pre-operatorio. Se requiere de un ensayo clínico que evalúe la administración de mifamurtida, prévio a la resección del tumor, en la población de interés del presente dictamen. CONCLUSIÓN: El Instituto de Evaluación de Tecnologías en Salud e Investigación-IETSI no aprueba el uso de mifamurtida para el manejo de los pacientes com diagnóstico de osteosarcoma (OS) osteoblástico no metastásico sin tratamento sistémico en el contexto de neoadyuvancia con quimioterapia MAPI.

ABSTRACT

INTRODUCCIÓN: El presente dictamen expone la evaluación de la eficacia y seguridad de mifamurtida, para el tratamiento de pacientes con osteosarcoma osteoblástico no metastásico sin tratamiento sistémico previo, en el contexto de adyuvancia con quimioterapia MAPI (metotrexato, doxorrubicina, cisplatino e ifosfamida). El osteosarcoma (OS) osteoblástico es un tumor maligno primario del esqueleto y la neoplasia primaria más común del hueso en niños y adultos jóvenes. Representa aproximadamente el 20 % de todos los tumores óseos primarios malignos y el 0.2 % de todos los tumores malignos. Su curva de distribución en cuanto a la edad es bimodal, con un primer pico en la adolescencia y otro después de los 65 años. La adición de quimioterapia a la cirugía ha mejorado considerablemente el pronóstico de los pacientes con enfermedad localizada, incrementando la tasa de curación de pacientes con OS en las extremidades y sin enfermedad metastásica evidente de 10-15 % a 50-70 %. En la actualidad el Petitorio Farmacológico de EsSalud cuenta con metotrexato, doxorrubicina, cisplatino e ifosfamida (MAPI) como opción de régimen quimioterapéutico para OS. Sin embargo, se considera que la adición de mifamurtida al esquema MAPI podría ser de potencial beneficio para los pacientes con osteosarcoma en el contexto de adyuvancia. Así, el presente dictamen preliminar tiene como objetivo evaluar la eficacia y seguridad del uso de mifamurtida en combinación con MAPI en pacientes con osteosarcoma osteoblástico no metastásico que no han recibido tratamiento previo, en el contexto de adyuvancia.TECNOLOGIA SANITARIA DE INTERES: Mifamurtida (Mepact, Takeda) es un compuesto químico biológicamente activo con actividad inmunomoduladora, clasificándose como un adyuvante biológico y perteneciente al grupo farmacoterapéutico de los inmunoestimulantes . El compuesto es un derivado totalmente sintético del muramil dipéptido (MDP), el estimulante inmunológico natural más pequeño de las paredes celulares de las micobacterias (37) . Al igual que la MDP, la mifamurtida es reconocida por el receptor de reconocimiento de patrones NOD2, localizado en varios tipos de glóbulos blancos, principalmente monocitos y macrófagos. De tal manera, mifamurtida simula una infección bacteriana, resultando en una activación de los macrófagos y un incremento en la producción de TNF-alfa, interleuquina 1, 6, 8 y 12, y moléculas de adhesión (e.g., ICAM-1 y LFA-1). Se desconoce el mecanismo de acción antitumoral exacto de la mifamurtida, pero estudios in vitro reportan que ésta induce a los glóbulos blancos a liberar sustancias químicas que matan a las células cancerosas, mas no a las células normales. METODOLOGÍA: Se llevó a cabo una búsqueda sistemática de la literatura con respecto a la eficacia y seguridad del uso de mifamurtida para el tratamiento de pacientes con osteosarcoma osteoblástico no metastásico sin tratamiento sistémico previo, en el contexto de adyuvancia con quimioterapia MAPI (metotrexato, doxorrubicina, cisplatino e ifosfamida). La búsqueda se realizó utilizando las bases de datos: National Library of Medicine (PubMed, 09/2017), Web of Science (WoS, 09/2017), y Centre for Reviews and Dissemination (CRD, 09/2017). Adicionalmente, se amplió la búsqueda revisando la evidencia generada por grupos internacionales que realizan revisiones sistemáticas (RS), evaluaciones de tecnologías sanitarias (ETS) y guías de práctica clínica (GPC), tales como The Cochrane Library (09/2017), The National Institute of Health and Care Excellence (NICE, 08/2017) del Reino Unido, The National Guidelines of Clearinghouse (NGC, 08/2017) de los Estados Unidos, The Scottish Intercollegiate Guidelines Network (SIGN, 08/2017) de Escocia, Australian Clinical Practice Guidelines (08/2017), The Royal Childrens Hospital Melbourne Practice Guidelines de Australia (08/2017), CMA Infobase de la Canadian Medical Association (08/2017), American College of Physicians Clinical Practice Guidelines and Recommendations (08/2017) de los Estados Unidos, Guidelines International Network (GIN, 08/2017), New Zealand Guidelines Group (NZGG, 08/2017) de Nueva Zelanda, Guía Salud de España (08/2017, 08/2017), y el Centro Nacional de Excelencia Tecnológica en Salud (CENETEC) de México. Esta búsqueda se completó revisando publicaciones de grupos dedicados a la educación, investigación y mejora de la práctica clínica oncológica dentro de América y Europa, como The National Comprehensive Cancer Network (NCCN, 09/2017) de los Estados Unidos, y The European Society for Medical Oncology (ESMO, 08/2017). Por último, se completó la búsqueda ingresando a la página web www.clinicaltrials.gov, para así poder identificar ensayos clínicos en elaboración o que no hayan sido publicados aún, y así disminuir el riesgo de sesgo de publicación. RESULTADOS: Según las cuatro guías de práctica clínica (GPC) incluidas en el presente dictamen en relación al tratamiento de pacientes con OS no metastásico resecable, tres hacen mención al uso de mifamurtida en un contexto de adyuvancia (post-operatorio) y una no se pronuncia al respecto dado que el compuesto no tiene licencia en el país de publicación de la guía (i.e., no tiene aprobación por la Administración de Alimentos y Medicamentos de los Estados Unidos (FDA, por sus siglas en inglés)). Si bien tres GPC hacen mención al uso de mifamurtida, éstas brindan indicaciones discordantes a pesar de basarse en el único ensayo clínico existente (INT-0133) y el mismo artículo que reporta sus hallazgos (Meyers et al., 2008): i) Sociedad Europea de Oncología Médica (SEOM) recomienda su uso como parte de la quimioterapia adyuvante acorde al protocolo del único ensayo clínico existente a la fecha (INT-0133); ii) Grupo de Trabajo de Sarcoma de la Red de Cáncer de Singapur (SCAN, por sus siglas en inglés) reporta que el efecto de la adición de la mifamurtida a la quimioterapia multiagente estándar aún es poco claro; y iii) Sociedad Europea de Oncología Médica (ESMO, por sus siglas en inglés) reporta que no existe un consenso en la Comunidad de Sarcomas sobre el uso de mifamurtida dada las debilidades del único ensayo clínico existente. En relación a las dos evaluaciones de tecnologías sanitarias (ETS) evaluadas, el Instituto Nacional de Salud y Cuidados de Excelencia (NICE, por sus siglas en inglés) recomienda el uso de mifamurtida para el tratamiento quimioterapéutico adyuvante de pacientes con OS no metastásico resecable basándose en resultados del único ensayo clínico existente a la fecha (INT-0113) y en la opinión de expertos, y luego de realizarse un descuento en el precio del medicamento. Por otro lado, la ETS de NCCN brinda únicamente un resumen de la evidencia existente respecto al uso de mifamurtida con quimioterapia adyuvante para pacientes con OS no metastásico resecable, mas no emite recomendación alguna sobre su uso. El único ensayo clínico que evalúa el uso de mifamurtida dentro del régimen quimioterapéutico MAPI en un contexto adyuvante, reporta que no existe una diferencia estadísticamente significativa entre mifamurtida más MAPI en relación a MAP (metotrexato, cisplatino y doxorrubicina) solo con respecto a la sobrevida libre de eventos (HR 0.78, IC 95 %: 0.54 ­ 1.2; p=0.22), es de notar que las comparaciones se hicieron en relación al régimen estándar MAP y no MAPI, con lo cual no se podría determinar el efecto neto de la adición de mifamurtida a MAPI, sino de mifamurtida e ifosfamida a MAP. En relación a la sobrevida global (SG) no se presenta el valor p y se observa que el límite superior del intervalo de confianza es marginal al valor nulo de significancia (HR 0.71; IC 95 %, 0.52 ­ 0.96). Adicionalmente se observa i) interacción entre mifamurtida y quimioterapia, afectando el análisis marginal del ensayo, ii) falta de poder estadístico para comparar individualmente los cuatro regímenes quimioterapéuticos evaluados, y iii) la aparente falta de poder estadístico para evaluar el efecto de la adición de mifamurtida a los regímenes quimioterapéuticos en relación a la sobrevida global. Así, el único ensayo clínico que evalúa el efecto de la mifamurtida en pacientes con OS tienen serias limitaciones, las cuales no permiten estimar si existe un real beneficio de la adición de mifamurtida al régimen quimioterapéutico adyuvante. CONCLUSIÓN: El Instituto de Evaluaciones de Tecnologías en Salud e Investigación - IETSI no aprueba el uso de mifamurtida para el manejo de los pacientes con diagnóstico de osteosarcoma osteoblástico no metastásico sin tratamiento sistémico, en el contexto de adyuvancia con quimioterapia MAPI.

ABSTRACT

We hereby present a case of pre-treated unresectable sarcoma recurrence of the trunk which showed an excellent response to concomitant tri-modal therapy, consisting of re-irradiation, chemotherapy and regional hyperthermia even with a strong compromised re-irradiation dose. No significant toxicity of the combined therapy and fast achievement of the pain and neurological symptoms relief are reported. The case shows that concurrent tri-modality treatment can be considered as a therapeutic option for the management of pre-treated unresectable recurrence even in there-irradiation setting.

ABSTRACT

Trabectedin is an alkylating agent registered in Europe for the treatment of advanced metastatic soft-tissue sarcomas, whose activity has been documented mainly in liposarcomas or leiomyosarcomas. Here, we report the response achieved in a patient with lung metastases from synovial sarcoma. A man with a large synovial sarcoma of the axilla underwent three cycles of neoadjuvant epirubicin+ifosfamide before complete excision, followed by three additional cycles of chemotherapy and radiotherapy. After 14 months, bilateral lung metastases appeared and were first treated with a prolonged 14-day continuous infusion of high-dose ifosfamide without response, and then with second-line trabectedin. A partial radiological response was achieved; dosage was reduced to 1.1 mg/m because of mild asthenia, grade 3 neutropenia, grade 3 nausea and vomiting, and reversible transaminase elevation. After 9 months of treatment, the lung nodules progressed, the patient received sorafenib, but further progressed and died 19 months after the first appearance of lung metastases. Trabectedin was the only drug that led to a radiological response in this patient with synovial sarcoma, despite being administered at 75% of the standard dose because of dose-limiting nausea and vomiting, in line with more recent data demonstrating activity in translocated sarcomas. We believe that trabectedin represents an attractive option for the treatment of metastatic synovial sarcoma and further clinical studies are warranted.

ABSTRACT

OBJECTIVE: To investigate the electronic anti-nausea instrument (EANI) combined with hydrochloride palonosetron for prevention of chemotherapy-induced nausea and vomiting following highly emetogenic chemotherapy. METHODS: Patients who received highly emetogenic chemotherapy were randomly assigned to a treatment group (60 patients) treated with EANI combined with hydrochloride palonosetron, and control group (also 60 patients) given only hydrochloride palonosetron. Chemotherapy related nausea and vomiting were observed and recorded in both groups of patients from the start till the end of chemotherapy. RESULTS: Complete control rates of vomiting in treatment and control group were 40%, and 35%, respectively, without any statistical ly significant difference (p> 0.05); however the response rates are 95.0%, 78.3%, respectively, with statistical difference (p< 0.05). Complete control rates of nausea in treatment and control group were 36.7%, 30%, respectively, without statistical difference (p> 0.05); but the response rates are 90.0%, 76.7%, respectively, with statistical difference (p<0.05). CONCLUSION: EANI combined with hydrochloride palonosetron for prevention of nausea and vomiting induced by chemotherapy could be more effective than hydrochloride palonosetron alone, and can be recommended for use in prevention and treatment of chemotherapy-induced nausea and vomiting following highly emetogenic chemotherapy.

ABSTRACT

UNLABELLED: In a prospective study of newly diagnosed or relapsed histologically proven extranodal natural killer/T-cell lymphoma (ENKTL) patients, we aimed to determine the accuracy of midtreatment (18)F-FDG PET for response assessment using both visual and quantitative analyses. METHODS: Twenty-four patients (12 men, 12 women; median age, 50 y; age range, 16-83 y) were referred for pre-, mid- (after 2-3 cycles of SMILE [prednisolone, methotrexate, ifosfamide, L-asparaginase, etoposide] chemotherapy), and end-treatment PET/CT scans (n = 24, 24, and 17, respectively) using a standardized protocol. Sixty-five PET/CT scans were analyzed visually using the Deauville 5-point score (DS), and the lesion with the highest maximum standardized uptake value (SUV(max)) was recorded. Survival curves were obtained using Kaplan-Meier analysis and compared using the log rank test, followed by multivariate analysis using the Cox proportional hazards model to assess the independent effects of International Prognostic Index (IPI) score (0-1 vs. 2-5), stage (stage I/II vs. stage III/IV), sex, DS (1-3 vs. 4-5), SUV(max), and change in SUV(max) on overall survival (OS) and progression-free survival (PFS). The mean (±SD) follow-up period was 32 mo (±21 mo). RESULTS: For 2-y OS, the following parameters were predictive: IPI score (P = 0.047), DS at mid- and end-treatment (P < 0.001), and SUV(max) at mid- and end-treatment (P < 0.001 and 0.045, respectively). For 2-y PFS, the following parameters were predictive: sex (P = 0.006), stage (P = 0.034), IPI score (P = 0.038), DS at mid- and end-treatment (P < 0.001 and 0.001, respectively), and SUV(max) at midtreatment (P = 0.001). Multivariate analysis showed DS on mid- and end-treatment scans to be the only significant independent predictor of both OS (P = 0.004 and 0.018, respectively) and PFS (P = 0.004 and 0.014, respectively). The 2-y estimate for OS and PFS was 81% and 62%, respectively, in patients with a DS of 1-3, compared with 17% in patients with a DS of 4-5 (P < 0.001 and 0.001, respectively). The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of the midtreatment DS for prediction of OS and PFS were 63%, 94%, 83%, 83%, and 83%, respectively. CONCLUSION: Midtreatment PET/CT is a valuable tool for early treatment response assessment in extranodal natural killer/T-cell lymphoma patients.

ABSTRACT

Basidiocarp of Agaricus blazei (=Agaricus brasiliensis; =Agaricus subrufescens) is used as teas or capsules due to its antineoplastic effect but there are few reports of using mycelium for this purpose. The objective of this study was to evaluate the antineoplastic activity on sarcoma 180 cells implanted in mice of two forms of preparation of the mycelium from two A. blazei strains grown in culture medium with different concentrations of isolated soy protein. Mycelia were grown in Pontecorvo medium with different concentrations of isolated soybean protein (ISP). Mycelial hot water extract, moistened mycelial powder, hot water extract of green tea, Ifosfamida(®) (ifosfamide drug), and saline solution were administered daily by gavage in mice with sarcoma 180 cells to evaluate antineoplastic activity. It was concluded that antineoplastic activity was the same for both strains, except when used as moistened mycelial powder, which rules out the use of mycelial powder in capsules. Mycelial hot water extract had high antineoplastic activity with lower metabolic demand on the spleen and maintenance of normal blood parameters. Mycelial growth in different ISP concentrations had the same antineoplastic activity. Also the vegetative mycelium was as effective as the basidiocarp for sarcoma 180 tumor inhibition. Green tea was as effective as mycelial hot water extract.

ABSTRACT

Ifosfamide is commonly used as a chemotherapeutic agent in children. The authors report a 4-y-old boy who developed proximal renal tubulopathy with florid rickets a year after completion of ifosfamide therapy for Ewing's sarcoma. After initiation of treatment, there was complete healing of rickets and he did not need supplements beyond 18 mo. Growth monitoring and musculoskeletal system examination is important in all children who have received ifosfamide therapy. Routine monitoring for nephrotoxicity during and after ifosfamide therapy helps in early identification and intervention.

ABSTRACT

AIM: To describe drugs used in the chemotherapy of testis and penis neoplasms. MATERIAL: Bibliographical search was performed from the database Medline (National Library of Medicine, PubMed) and websites of the HAS and the ANSM. The search was focused on the characteristics, the mode of action, the efficiency and the side effects of the various drugs concerned. RESULTS: Nowadays, the chemotherapy is perfectly codified in adjuvant treatment or in first-line treatment of metastatic testis cancer. A single dose of carboplatin for seminoma testicular (stage I) in adjuvant treatment situation is one of the latest advances. Concerning penis cancer, the optimal protocols validated by a high level of evidence are missing. CONCLUSION: The chemotherapy in testis and penis neoplasms knew few advances in recent years. So, it is necessary to include patients in clinical research protocols.

ABSTRACT

Nephrotoxicity is a serious side effect associated with ifosfamide use. It can affect up to 30% of children who are treated with this chemotherapeutic drug, and treatment may necessitate lifelong supplementations, renal dialysis, renal transplant, and in severe cases may result in death. The antioxidant n-acetylcysteine is a promising strategy for mitigating this renal toxicity. It is currently used in children for acetaminophen overdose in the 21-hour IV protocol, a dose which has also been suggested to provide renal protection against ifosfamide. Of significance, both in vitro and in vivo studies suggest n-acetylcysteine does not interfere with the antitumor actions of ifosfamide. Most importantly, n-acetylcysteine has successfully protected against ifosfamide-induced nephrotoxicity in both cell and rodent models, as well as in several paediatric cases, suggesting it should be evaluated as a treatment option for children on ifosfamide who present with renal dysfunction. The purpose of this paper is to outline strategies and recommendations for treating patients at risk or suffering from nephrotoxicity during ifosfamide therapy. These recommendations may be used when deciding who to treat, how and when to treat, as well as several considerations when exact recommendations cannot be met. They have been created to increase both the quality of care and quality of life of paediatric oncology patients.

ABSTRACT

Ifosfamide is a chemotherapeutic prodrug used in the treatment of several tumor entities, including bone and soft-tissue sarcoma. However, the application of high-dose ifosfamide is not feasible because of severe side effects caused by metabolites. The active metabolite isophosphoramide mustard is not suitable for administration because of chemical instability. ZIOPHARM Oncology Inc, under license from Dekk-Tec Inc, is developing palifosfamide, a formulation of isophosphoramide mustard with tris(hydroxymethyl)aminomethane salt-stabilization (palifosfamide-tris) and previously with lysine-stabilization (palifosfamide-lys). Preclinical studies and phase I and I/II clinical trials demonstrated that palifosfamide-tris had an antitumor efficiency comparable or superior to that of ifosfamide. Patients treated with palifosfamide-tris did not display any of the neurotoxic or nephrotoxic side effects associated with ifosfamide. At the time of publication, data from phase II trials were being evaluated and phase III trials were being planned. palifosfamide-tris is expected to be a safer and less toxic alternative to ifosfamide; however, considering other new approaches under investigation for tumors such as sarcoma, such as molecular-based treatment strategies, it is unclear what position palifosfamide-tris might occupy on the market.

ABSTRACT

PURPOSE: To compare the radiological criteria RECIST, WHO, and tumor volume for evaluation of tumor response in patients with soft tissue sarcomas (STS) showing either good or poor pathohistological response to neoadjuvant chemotherapy combined with regional hyperthermia, and to examine the dependence of the findings on the applied thermal dose. MATERIALS AND METHODS: 19 patients with pathohistological complete response (no vital tumor cells, group 1) and 27 with pathohistological no response (<25% necrosis, group 2) were selected from our previous clinical trials. The change in tumor size before and after therapy was determined. Intratumoral temperature (T(90)) and thermal dose (CEM 43 degrees C T(90)) were calculated for 13 patients. RESULTS: In the first group, 6 partial response (PR) and 13 stable disease (SD) according to RECIST, 7 PR and 12 SD according to WHO, 7 PR and 12 SD according to volumetric criteria were evaluated. In the second group, the results were 10 PR and 17 SD (RECIST), 9 PR and 18 SD (WHO), 8 PR and 19 SD (volume). The concordance of these criteria was 73.7% in group 1 and 74% in group 2. PR and SD were equally distributed in both groups (p > 0.421). Thermal parameters were not different between the groups (p > 0.327). CONCLUSIONS: SD or PR in radiological response assessment does not correlate with the pathohistological response after neoadjuvant thermochemotherapy. RECIST, WHO and volumetric criteria for response evaluation in STS are in substantial agreement. For irregularly shaped lesions, volumetric criteria seem to be more appropriate.
