Predicted cardiac and second cancer risks for patients undergoing VMAT for mediastinal Hodgkin lymphoma

Background and purpose To predict treatment-related cardiovascular disease (CVD) and second cancer 30-yea. absolute mortality risks (AMR30) for patients with mediastinal Hodgkin lymphoma in a large multicentre radiation oncology network in Ireland. Material and methods This study includes consecutive patients treated for mediastinal lymphoma using chemotherapy and involved site radiotherapy (RT) 2016–2019. Radiation doses to heart, left ventricle, cardiac valves, lungs, oesophagus, carotid arteries and female breasts were calculated. Individual CVD and second cancer AMR30 were predicted using Irish background population rates and dose–response relationships. Results Forty-four patients with Hodgkin lymphoma were identified, 23 females, median age 28 years. Ninety-eight percent received anthracycline, 80% received 4–6 cycles ABVD. Volumetric modulated arc therapy (VMAT) ± deep inspiration breath hold (DIBH) was delivered, median total prescribed dose 30 Gy. Average mean heart dose 9.8 Gy (range 0.2–23.8 Gy). Excess treatment-related mean AMR30 from CVD was 2.18% (0.79, 0.90, 0.01, 0.13 and 0.35% for coronary disease, heart failure, valvular disease, stroke and other cardiac diseases), 1.07% due to chemotherapy and a further 1.11% from RT. Excess mean AMR30 for second cancers following RT were: lung cancer 2.20%, breast cancer in females 0.34%, and oesophageal cancer 0.28%. Conclusion For patients with mediastinal lymphoma excess mortality risks from CVD and second cancers remain clinically significant despite contemporary chemotherapy and photon-RT. Efforts to reduce the toxicity of combined modality treatment, for example, using DIBH, reduced margins and advanced RT, e.g. proton beam therapy, should be continued to further reduce potentially fatal treatment effects (AU)

Histiocitosis: a propósito de dos casos clínicos / Histiocytosis: report of two clinical cases

INTRODUCCIÓN: La histiocitosis es una patología infrecuente consistente en una proliferación incontrolada y acumulación de células de Langerhans, más frecuente en hueso con una clínica poco específica. El número y tipo de órganos afectados es lo que marca la clasificación y la necesidad de tratamiento quimioterápico en esta patología. Caso clínico 1: Presentamos un caso de histiocitosis ósea que es interpretado inicialmente como hematoma. Caso clínico 2: Presentamos un caso de histiocitosis ósea que debuta como otorrea de 4 semanas de evolución, siendo diagnosticada al inicio de otitis purulenta. CONCLUSIONES: A pesar de su rareza, la histiocitosis es una enfermedad a tener en cuenta al evaluar la persistencia de lesiones, tumoraciones o patología que en un primer momento puede parecer banal. Los avances respecto al conocimiento de la patogénesis de esta enfermedad y el descubrimiento de genes implicados abren el camino a nuevas terapias dirigidas

INTRODUCTION: Histiocytosis is an uncommon pathology, consisting of an uncontrolled proliferation and accumulation of Langerhans cells. It most often affects the bones with an unspecified clinical presentation. The amount and kind of affected organs is what marks the classification and the necessity of chemotherapy treatment in this pathology. Clinical case 1: We present a case of histiocytosis of bone initially interpreted as an hematoma. Clinical case 2: We present a case of histiocytosis of bone which starts as an otorrhea lasting 4 weeks. It was diagnosed at the beginning with purulent otitis. CONCLUSIONS: Despite its infrequency, histiocytosis is a disease that should be considered when assessing the persistence of lesions, tumors or pathology that may initially seem banal. Advances in the knowledge of the pathogenesis of this disease and the discovery of the genes involved open the way to new targeted therapies

Poliartritis y glomerulonefritis membranoproliferativa como manifestaciones paraneoplásicas de linfoma de Hodgkin: presentación de un caso y revisión de literatura / Polyarthritis and membranoproliferative glomerulonephritis as paraneoplastic manifestation of Hodgkin's lymphoma: a case report and literature review

Los síndromes paraneoplásicos pueden presentarse de múltiples maneras, dentro de las cuales destacan las manifestaciones endocrinológicas, reumatológicas, hematológicas y nefrológicas. Si bien la mayoría de las publicaciones describen los tumores sólidos como responsables de dichos cuadros, las neoplasias hematológicas son causa importante a considerar como parte del diagnóstico diferencial. Se presenta el caso de un varón de 46 años con un cuadro de poliartritis simétrica seronegativa de grandes y pequeñas articulaciones, asociado a glomerulonefritis membranoproliferativa con depósitos de inmunocomplejos y deterioro agudo de la función renal, como parte de un síndrome paraneoplásico secundario a un linfoma de Hodgkin clásico con invasión medular, el cual revirtió completamente con el tratamiento de quimioterapia (AU)

Paraneoplastic syndromes can be presented in multiple ways, which include endocrinological, hematologic, rheumatologic and nephrologic manifestations. While most of the publications described solid tumors as responsible for these manifestations, hematologic neoplasms are important cause to consider as part of the differential diagnosis. We report the case of a 46 year-old man with seronegative symmetric polyarthritis of large and small joints associated with membranoproliferative glomerulonephritis with deposits of immune complexes and acute impairment of renal function, as part of a paraneoplastic syndrome secondary of a classical Hodgkin lymphoma with bone marrow invasion, which reversed completely with chemotherapy treatment (AU)

On the prediction of Hodgkin lymphoma treatment response

Purpose. The cure rate in Hodgkin lymphoma is high, but the response along with treatment is still unpredictable and highly variable among patients. Detecting those patients who do not respond to treatment at early stages could bring improvements in their treatment. This research tries to identify the main biological prognostic variables currently gathered at diagnosis and design a simple machine learning methodology to help physicians improve the treatment response assessment. Methods. We carried out a retrospective analysis of the response to treatment of a cohort of 263 Caucasians who were diagnosed with Hodgkin lymphoma in Asturias (Spain). For that purpose, we used a list of 35 clinical and biological variables that are currently measured at diagnosis before any treatment begins. To establish the list of most discriminatory prognostic variables for treatment response, we designed a machine learning approach based on two different feature selection methods (Fisher’s ratio and maximum percentile distance) and backwards recursive feature elimination using a nearest-neighbor classifier (k-NN). The weights of the k-NN classifier were optimized using different terms of the confusion matrix (true- and false-positive rates) to minimize risk in the decisions. Results and conclusions. We found that the optimum strategy to predict treatment response in Hodgkin lymphoma consists in solving two different binary classification problems, discriminating first if the patient is in progressive disease; if not, then discerning among complete and partial remission. Serum ferritin turned to be the most discriminatory variable in predicting treatment response, followed by alanine aminotransferase and alkaline phosphatase. The importance of these prognostic variables suggests a close relationship between inflammation, iron overload, liver damage and the extension of the disease (AU)

Biweekly vinorelbine and tegafur/uracil in patients with metastatic breast cancer previously treated with anthracyclines and taxanes: GEICAM 2000-02 phase II study

INTRODUCTION: To assess the efficacy and safety profile of biweekly vinorelbine and tegafur/uracil (UFT) as treatment in patients with metastatic breast cancer previously treated with anthracyclines and taxanes. PATIENTS AND METHODS: Patients with histologically confirmed breast cancer, measurable disease, no more than one prior chemotherapy regimen for metastatic disease, an Eastern Cooperative Oncology Group (ECOG) performance status ≤2, and adequate bone marrow, renal and liver function were eligible. Patients received vinorelbine (30 mg/m(2) on day 1) and UFT (250 mg/m(2) daily) every two weeks for 12 cycles unless progression or unacceptable toxicity was observed. RESULTS: Thirty-seven patients were included and received 311 cycles of chemotherapy. Efficacy and toxicity analyses were carried out on an intention-to-treat basis. The overall response rate was 35% (95% CI: 20-53). With a median follow-up of 18.6 months (95% CI: 1.0-74.3), the median time to progression was 7.0 months (96% CI: 5.2-8.9) and the median overall survival was 19.4 months (95% CI: 11.1-27.8). The most common severe toxicities were neutropenia (38% of patients) and asthenia (11% of patients). CONCLUSION: The combination of biweekly vinorelbine and UFT in patients with metastatic breast cancer pretreated with anthracyclines and taxanes is a well tolerated and effective regimen.

Análisis de la inflamación luminal inducida por distintos tipos de stent coronario en el modelo coronario animal mediante microscopía electrónica de barrido / Scanning electron microscopy analysis of luminal inflammation induced by different types of coronary stent in an animal model

Los stents farmacoactivos se asocian con retraso en la endotelización y fenómenos inflamatorios persistentes demostrados histológicamente. En la superficie luminal, mediante microscopio electrónico de barrido se observan también cúmulos de células inflamatorias. Para cuantificar esta respuesta inflamatoria se implantaron un stent de acero y dos stents farmacoactivos con distintas dosis de vinblastina y el mismo polímero en las coronarias de 12 cerdos domésticos. Se analizó 3 y 7 días después la densidad de células inflamatorias por área representativa (100 x 100 mm). La endotelización del stent de acero fue más completa que en los stents farmacoactivos a los 3 días (p=0,016) y a los 7 días (p=0,0001). Los stents farmacoactivos indujeron un grado de inflamación mayor que los stents de acero a los 3 días (11,8±3.5% frente al 4,5±2%; p=0,001) y a los 7 días (26,3±4,4% frente al 1,2±1,5%; p=0,0001), con un patrón opuesto: la respuesta inflamatoria aumentaba con el tiempo en los stents farmacoactivos, al contrario de lo que sucedía con los stents de acero (AU)

There is histological evidence that drug-eluting stents are associated with delayed endothelialization and a persistent inflammatory state. Moreover, clusters of inflammatory cells have been observed on luminal surfaces by scanning electron microscopy. With the aim of quantifying this inflammatory response, we implanted one bare-metal stent and two drug-eluting stents containing different doses of vinblastine embedded in the same polymer into the coronary arteries of 12 domestic pigs. The density of inflammatory cells in a representative area (100 x 100 mm) was quantified at 3 and 7 days. Endothelialization was more complete in bare-metal stents than in drug-eluting stents at both 3 days (P = .016) and 7 days (P = .0001). The degree of inflammation induced by the drug-eluting stents was higher than that induced by the bare-metal stents at both 3 days (11.8 +/- 3.5% vs. 4.5 +/- 2%; P = .001) and 7 days (26.3 +/- 4.4% vs. 1.2 +/- 1.5%; P = .0001). In addition, the time sequence was inverted: the inflammatory response increased over time with the drug-eluting stents, while the opposite occurred with the bare-metal stents (AU)

Empleo de M-VAC en el tratamiento adyuvante del carcinoma sarcomatoide de vejiga / Use of M-VAC in the adjuvant treatment of sarcomatoid carcinoma of the bladder

El carcinoma sarcomatoide de vejiga es una neoplasia de alto grado, que representa aproximadamente el 0,3% de todas las neoplasias vesicales y tiene su origen en las células transicionales de la vejiga. El carcinoma sarcomatoide se caracteriza por presentar un componente epitelial y un componente sarcomatoide, consistente en células fusiformes que solamente expresan marcadores de estirpe epitelial. Presentamos el caso de una mujer de 26 años diagnosticada de un carcinoma sarcomatoide de vejiga estadio III (T3aN0M0) tratada con cistectomía parcial seguida por 4 ciclos de quimioterapia adyuvante con metotrexato, vinblastina, adriamicina y cisplatino (AU)

Sarcomatoid bladder carcinoma is a high-grade neoplasm and accounts for approximately 0,3% of all bladder malignancies. Sarcomatoid carcinoma originates from transitional cells of the bladder. Sarcomatoid carcinoma is charactericed by a epithelial component and a sarcomatoid component, consisting of spindle cells, that is only epithelial marker-positive. We report a 26 year-old woman diagnosed of stage III sarcomatoid bladder carcinoma (T3aN0M0) treated with partial cistectomy followed by 4 cycles of adjuvant chemotherapy with methotrexate, vinblastine, doxorubicin and cisplatin (AU)

Tumores del tracto urinario superior. Nuestra experiencia / Tumors of the upper urinary tract. Our experience

Objetivo: Estudiar la clínica, el diagnóstico, el tratamiento, y la evolución de los tumores del tracto urinario superior. Métodos: Se realizó un estudio retrospectivo de los tumores del aparato urinario superior tratados en nuestro centro, HCU Valladolid, entre 1994 y 2007. Resultados: Se diagnosticaron 65 tumores, de los cuales sólo 59 entraron en el estudio. La edad media de los pacientes fue de 68 años (intervalo entre 46 y 88 años). Nos encontramos 47 varones frente a 12 mujeres. La hematuria fue el signo clínico inicial más frecuente, apareciendo en el 79,9% de los casos. La Urografía fue la técnica diagnóstica más utilizada (96,6%). La técnica quirúrgica más empleada fue la nefroureterectomía con desinserción endoscópica del uréter, realizada en 28 ocasiones. En 9 pacientes se aplicó tratamiento conservador vía percutánea con una única recidiva y en 2 tratamiento ureteroscópico. El 50,9% de los tumores fueron superficiales. Hubo un 37% de afectación vesical concomitante. La supervivencia a los cinco y diez años fue del 55 y 47% respectivamente. Conclusiones: Los tumores de aparato urinario superior son una entidad rara, que aparece en la edad media-avanzada de la vida. La nefroureterectomía radical es hoy por hoy el tratamiento estandar, ya sea vía abierta o laparóscopica. El tratamiento endóscopico cada vez tiene más importancia y presenta excelentes resultados en casos seleccionados (AU)

Objectives: To study the clinical presentation, diagnosis, treatment, and evolution of upper urinary tract tumours. Methods: We carried out a retrospective study on the upper urinary tract tumours treated in our centre, HCU Valladolid, between 1994 and 2007. Results: 65 tumours were diagnosed, although only 59 were valid for the study. Mean patient age was 68 years (interval between 46 and 88 years). 47 were men and 12 women. The most common symptom on presentation was hematuria (79,9%). Urography was the most frequently used diagnostic technique (96,6%) and nephroureterectomy with transurethral resection of the intramural ureter was the most common surgical treatment performed, carried out in 28 cases. 9 patients underwent percutaneous treatment with only one recurrence, and 2 patients received ureteroscopic treatment. 50,9 % of the lesions were classified as superficial tumours. The 5 and 10-year survival rates were 55 and 47%. Conclusions: Upper urinary tract tumours are an unusual disease characteristic of medium-advanced ages. Nowadays nephroureterectomy by open surgery or laparoscopy is the standard treatment. Conservative endoscopic procedures have more and more importance and present excellent results in highly selected cases (AU)

Ascitis mielomatosa. Reporte de un caso y revisión de la literatura / Myelomatous ascites

Ascites is rare in patients with multiple myeloma (MM). It may be due to diverse mechanisms, most frequently because of an increased permeability of the peritoneum or because of portal hypertension due to liver infiltration. Myelomatous ascites occurs more frequently in patients having Ig-G or Ig-A paraprotein and their prognosis is poor. It is submitted the case of a female patient aged 50 years with IgA-kappa MM, who evolved with cardiac failure (CF), plasma cells leukemia and ascites of mixed cause, because of peritoneal infiltrate of myelomatous cells, hepatic compromise and CF. A review of the different causes of ascites in patients with MM is performed. There are also summarized all myelomatous ascites cases published in the literature. Our report presents the first case of myelomatous ascites in a patient with plasma cells leukemia

Los pacientes con mieloma múltiple (MM) raramente presentan ascitis. La misma puede responder a diversos mecanismos, siendo las causas más frecuentes el aumento de permeabilidad del peritoneo y la hipertensión portal por infiltración hepática. La ascitis mielomatosa (AM) ocurre con más frecuencia en pacientes con paraproteína de tipo Ig-G e Ig-A y su pronóstico es sombrío. Se presenta el caso de una paciente de sexo femenino de 50 años con diagnóstico de MM IgA-kappa que evoluciona con insuficiencia cardíaca (IC), leucemia de células plasmáticas y ascitis de causa mixta, por infiltración peritoneal por células mielomatosas, compromiso hepático e IC. Se realiza una revisión de las distintas causas de ascitis en pacientes con MM. Asimismo se resumen todos los casos publicados en la literatura mundial de AM. Nuestro reporte representa el primer caso de AM en un paciente con leucemia de células plasmáticas

Assessment of functional status, symptoms and comorbidity in elderly patients with advanced non-small-cell lung cancer (NSCLC) treated with gemcitabine and vinorelbine

BACKGROUND: The incidence and prevalence of comorbid conditions in lung cancer patients increase with age. The aim of the study was to determine response and tolerability with the biweekly combination gemcitabine-vinorelbine in elderly non-small-cell lung cancer (NSCLC) patients. In order to characterise the population included in the study well and assess the results achieved properly, an evaluation of the functional status, comorbidity and survival was performed. PATIENTS AND METHOD: Between June 2001, and December 2003, 59 untreated advanced NSCLC patients over the age of 70 years entered the study. Treatment consisted of gemcitabine 1750 mg/m(2) and vinorelbine 30 mg/m(2) on day 1 every two weeks. The response was evaluated every f ive cycles (RECIST guidelines). Comorbidity was evaluated according to the Charlson and Kaplan Feinstein scales. To measure functional status, activities of daily living (ADL) and instrumental ADL (IADL) were considered. RESULTS: Median age was 74; ECOG performance status was >2 in 59.3%; no dependence in ADL or IADL was found in 24.8% and 42.4% of patients, respectively. A total of 381 courses were administered. Grade 3-4 neutropenia was present in 6.8% of these courses and correlated with IADL. Objective response was 22% (95% CI 12-32). Mean global survival and cause-specific survival were 29 weeks (95% CI 19.9-38.1) and 32 weeks (95% CI 23.4-40.8) respectively. Comorbidity displayed no close correlation with functional status, but comorbidity according to the Kaplan Feinstein index correlated with IADL. Performance status, ADL, IADL and weight loss were significantly related to survival in multivariate analysis. CONCLUSIONS: This biweekly combination is feasible in elderly lung cancer patients with a high burden of comorbidity and dependence. Toxicity is acceptable, whereas response rate and survival fall in the range of active regimens. ADL and IADL indices allow the identification of elderly patients with a worse prognosis (AU)

Long term results of a phase II trial of induction chemotherapy with uracil-ftegafur (UFT), vinorelbine and cisplatin (UFTVP) followed by radiotherapy concomitant with UFT and carboplatin (RT/UFTJ) in non-resectable locally advanced (stage IV-B) squamous cell head and neck carcinoma and peripheral blood stem cell support (PBSCS) with febrile neutropenia

PURPOSE: To evaluate the response of advanced squamous cell head and neck carcinoma to a combination of induction chemotherapy and radiotherapy. METHODS: We present long-term results of a phase II trial of Induction Chemotherapy with UFT 200 mg/m(2) p.o. days 1 to 21, Vinorelbine 25 mg/m(2) i.v. days 1 and 8 and Cisplatin 100 mg/m(2) i.v. day 1 (UFTVP) each 21 days for 4 courses, followed by Radiotherapy concomitant with UFT 100 mg/m(2) p.o. daily and Carboplatin AUC = 0.5 i.v. weekly (RT/UFTJ) in patients (pts) with Non-Resectable Locally Advanced (Stage IV-B) Squamous Cell Head and Neck Carcinoma (IV-B-SCHNC). Primary endpoint was Complete Response to induction UFTVP and secondary endpoints were Disease Free Status Rate after locoregional treatment and long-term Overall Survival. Between 1994 and 1997, 32 pts were included. RESULTS: Complete Response to Induction UFTVP was 59% (95% CI: 48%-70%). Main toxicity of UFTVP was G 3,4 neutropenia (94% of pts; 25% developed febrile neutropenia and 1 of this pts dead). After Induction Chemotherapy with UFTVP, 30 pts received radiotherapy and 25 of them received concomitant Carboplatin and UFT (RT/UFTJ): main toxicity was mucositis (G3-4: 72%) and one patient died during RT/UFTJ because pneumonia. Twenty-five pts (78%) were alive and disease free at the end of the whole treatment. Actuarial 5 year Overall survival is 32%. CONCLUSION: Although toxicity is important, this approach has interesting activity and deserves further investigation (AU)
