Expert consensus: Profiling and management of advanced or metastatic epithelial ovarian cancer / Consenso de expertos basado en la evidencia: perfilamiento y manejo del carcinoma epitelial de ovario de alto grado avanzado.

Introduction and objective: The approach to patients with advanced or metastatic high-grade epithelial ovarian cancer (EOC) has evolved over time with the advent of new therapies and multimodal strategies. The objective of this consensus of experts is to generate national recommendations for the profiling and management of advanced or metastatic high-grade OEC, defined as stages III and IV of the "The International Federation of Gynecology and Obstetrics (FIGO) classification at the time of diagnosis to base on the literature review that included international evidence-based clinical practice guidelines (CPG). Material and methods: Eleven panelists (oncologists and gynecological oncologists) answered 8 questions about the profiling and management of advanced or metastatic ovarian epithelial carcinoma. The panelists were chosen for their academic profile and influence in national health institutions. Guidelines from the "ESMO Standardized Operating Procedures Consensus Conference" were used to develop the consensus. It was agreed that the level of agreement to accept a recommendation should be ≥ 80%. The document was peer reviewed. Results: Eight general recommendations are made, which are presented into five domains. Some of these recommendations are subdivided into specific recommendations. Initial treatment Recommendation 1.1 Complete primary cytoreduction (PCS) surgery is suggested as the initial therapy of choice for patients with high-grade or metastatic EOC, which should ideally be carried out in centers with experience, followed by adjuvant therapy. 1.2 Neoadjuvant chemotherapy followed by interval cytoreduction surgery (ICS) is suggested in those who are unlikely to achieve a complete cytoreduction in PCS either due to unresectable metastatic disease or who present unresectability criteria (imaging, laparoscopic and/or by laparotomy) and that have been defined by a gynecological oncologist and patients with poor functional status and comorbidities according to the criteria of the multidisciplinary team (clinical oncology, gynecological oncology, radiology, etc.). Recommendation 2. In patients with high-grade epithelial ovarian cancer (EOC), in stage III locally advanced or metastatic, who received neoadjuvant chemotherapy and achieved a complete or partial response (cytoreduction with tumor residue < 2.5 mm), the use of Hyperthermic IntraPeritoneal Chemotherapy (HIPEC) could be considered as an alternative to standard platinum-based adjuvant intravenous chemotherapy during interval cytoreductive surgery, after discussion in a multidisciplinary tumor board, at a center experienced in treating this type of patients. Use of genetic testing. Recommendation 3. It is suggested at the time of diagnosis to offer molecular genetic testing to all patients with high-grade advanced or metastatic EOC regardless of family history. Recommendation 4. It is suggested to offer genetic counseling, by qualified personnel, to all patients with high-grade advanced or metastatic EOC who are ordered genetic testing. Recommendation 5. It is suggested that all patients with advanced or metastatic high-grade EOC undergo a germ panel that includes the Breast Cancer Susceptibility Genes 1/2 genes (BRCA 1/2) and the other susceptibility genes according to with institutional protocols and the availability of genetic testing panels; If it is negative, then somatic testing should be performed that includes the homologous recombination deficiency (HRD) status, regardless of family history. Adjuvant Therapy Recommendation 6. 6.1. It is suggested that all patients with advanced stage III/IV EOC, with PSC of (0-2), got adjuvant intravenous chemotherapy as standard treatment within six weeks after Prc. It is suggested paclitaxel/carboplatin. Recommendation 6.2. It is suggested to use standard chemotherapy base on platinum plus Bevacizumab as adjuvant chemotherapy to patients with high-risk disease (EOC stage IV or stage III with suboptimal tumor cytoreduction), following by bevacizumab as maintenance. The use of bevacizumab as maintenance therapy is not recommended if bevacizumab was not included in the first line of treatment. We suggested the dose used in GOG-0218 and ICON7 trials. Recommendation 6.3 It is suggested combined intravenous/intraperitoneal chemotherapy only for selected patients, with optimal cytoreduction (residual lesions < 1 cm), especially those without residual disease (R0) and who are evaluated in a multidisciplinary meeting. It is not considered standard treatment. Recommendation 6.4. 6.4.1 It is suggested to use Poly ADP ribose polymerase (PARP) inhibitors such as olaparib or niraparib as maintenance after receiving first-line chemotherapy in patients with stage III/IV BRCA1/2 positive EOC who received platinumbased chemotherapy and obtained complete response/partial response (CR/PR), 6.4.2 It is suggested to use olaparib alone or in combination with bevacizumab or niraparib in patients with stage III/IV BRCA1/2 positive EOC who received platinum-based chemotherapy plus bevacizumab and achieved CR/PR. 6.4.3 It is suggested to use niraparibin patients with stage III/IV BRCA1/2 negative or unknown EOC who received platinum-based chemotherapy and achieved CR/PR. 6.4.4 It is suggested to use bevacizumab or olaparib plus bevacizumab in patients with EOC stage III/IV BRCA1/2 negative or unknown (HRD positive) who received platinum-based chemotherapy plus bevacizumab and obtained CR/PR. Treatment of disease relapse Recommendation 7. Secondary cytoreductive surgery followed by chemotherapy is suggested for selected patients with high-grade advanced EOC in first relapse, platinum-sensitive (platinum-free interval ≥ 6 months), positive "Arbeitsgemeinschaft Gynäkologische Onkologie ­ AGO" score or "I-model" positive (< 4.7) with a potential resection to R0 in centers with access to optimal surgical and postoperative support. Note: Platinum-free interval and AGO score have only been developed as positive predictors of complete resection and not to exclude patients from surgery. Recommendation 8. 8.1 For patients with relapse advanced high-grade EOC platinum-sensitive, the following is suggested: Platinum-based combination chemotherapy: carboplatin/liposomal doxorubicin or carboplatin/paclitaxel or carboplatin/nab-paclitaxel or carboplatin/docetaxel or carboplatin/gemcitabine) for six cycles. If combination therapy is not tolerated, give carboplatin or cisplatin alone. Combination chemotherapy (carboplatin/gemcitabine or carboplatin/paclitaxel or carboplatin/doxorubicin liposomal) plus bevacizumab followed by bevacizumab as maintenance (until progression or toxicity). Recommendation 8.2 For patients with relapsed advanced high-grade EOC platinum-resistant, it is suggested: Sequential treatment with chemotherapy, preferably with a non-platinum single agent (weekly paclitaxel or pegylated liposomal doxorubicin or docetaxel or oral etoposide or gemcitabine or trabectidine or, topotecan). Weekly paclitaxel or pegylated liposomal doxorubicin or topotecan could be administrate with or without bevacizumab. Other agents are considered potentially active (capecitabine, cyclophosphamide, ifosfamide, irinotecan, oxaliplatin, pemetrexed, vinorelbine, cyclophosphamide) could be recommended for later lines. Hormone receptor-positive patients who do not tolerate or have no response to cytotoxic regimens may receive hormone therapy with tamoxifen or other agents, including aromatase inhibitors (anastrozole and letrozole) or leuprolide acetate, or megestrol acetate. Patients with a performance score ≥ 3 should be considered only for best supportive care. Recommendation 8.3 Maintenance therapy with PARP inhibitors: It is suggested in patients with relapse advanced high-grade EOC stage III/IV BRCA1/2 (positive, negative or unknown) who have received two or more lines of platinum-based chemotherapy and have achieved CR/PR, use olaparib, niraparib or rucaparib. Niraparib could be useful in BRCA 1/2 +/-/unknown patients, as rucaparib, however, the latter does not yet have approval from the regulatory office in Colombia. Conclusions: It is expected that the recommendations issued in this consensus will contribute to improving clinical care, oncological impact, and quality of life of these women.

Introducción y objetivo: el abordaje de pacientes con cáncer epitelial de ovario (CEO) de alto grado avanzado o metastásico ha ido evolucionando a través del tiempo con el advenimiento de nuevas terapias y estrategias multimodales. El objetivo de este consenso de expertos es generar recomendaciones nacionales para el perfilamiento y manejo del CEO de alto grado avanzado o metastásico, definido como estadios III y IV de la clasificación de la Federación Internacional de Ginecología y Obstetricia (FIGO) al momento del diagnóstico, a partir de la revisión de la literatura que incluyó guías de práctica clínica (GPC) internacionales basadas en la evidencia. Materiales y métodos: once panelistas (oncólogos y ginecólogos oncólogos) respondieron ocho preguntas sobre el perfilamiento y manejo del carcinoma epitelial de ovario avanzado o metastásico. Los panelistas fueron escogidos por su perfil académico e influencia en instituciones de salud nacionales. Para el desarrollo del consenso se utilizaron los lineamientos de la "Conferencia de consenso de procedimientos operativos estandarizados de ESMO". Se definió que el nivel de acuerdo para aceptar una recomendación debía ser ≥ 80%. El documento fue revisado por pares. Resultados: Se hacen 8 recomendaciones generales, presentadas en cinco dominios; algunas de ellas se subdividen en recomendaciones específicas. Tratamiento inicial Recomendación 1 1.1. Como terapia inicial de elección para pacientes con CEO de alto grado o metastásico se sugiere la cirugía de citorreducción primaria (Cpr) completa que, idealmente, debe realizarse en centros con experiencia, seguida de terapia adyuvante. 1.2. Se sugiere quimioterapia neoadyuvante seguida de cirugía de citorreducción de intervalo (Cint) en quienes sea improbable alcanzar una citorreducción completa en la Cpr, bien sea por enfermedad metastásica no resecable o que presenten criterios de irresecabilidad (imagenológicos, laparoscópicos o por laparotomía) que hayan sido definidos por un ginecólogo oncólogo. También en pacientes con un pobre estado funcional y comorbilidades de acuerdo con el criterio del equipo multidisciplinario (oncología clínica, ginecología oncológica, radiología, etc.). Recomendación 2. En pacientes con CEO de alto grado, en estadio III localmente avanzado o metastásico, que recibieron quimioterapia neoadyuvante y alcanzaron respuesta completa o parcial (citorreducción con residuo tumoral < 2,5 mm), se podría evaluar el uso de la quimioterapia intraperitoneal hipertérmica (Hyperthermic IntraPeritoneal Chemotherapy - HIPEC) como alternativa a la quimioterapia IV adyuvante estándar basada en platinos durante la Cint, previa discusión en junta multidisciplinaria, en un centro de experiencia en este tipo de pacientes. Uso de pruebas genéticas Recomendación 3. Al momento del diagnóstico, se sugiere ofrecer testeo molecular genético a toda paciente con CEO de alto grado avanzado o metastásico, independientemente de la historia familiar. Recomendación 4. Se sugiere ofrecer asesoramiento genético, por parte de personal calificado, a toda paciente con CEO de alto grado avanzado o metastásico a quien se le ordene un testeo genético. Recomendación 5. Se sugiere que a toda paciente con CEO de alto grado avanzado o metastásico se le realice panel germinal que incluya los genes de susceptibilidad al cáncer de mama 1/2 (BRCA 1/2) y los otros genes de susceptibilidad de acuerdo con los protocolos institucionales y la disponibilidad de paneles de testeo genético; si es negativo entonces se debería realizar testeo somático que incluya el estatus de deficiencia de la recombinación homóloga (homologous recombination deficiency - HRD), independientemente de la historia familiar. Terapia adyuvante Recomendación 6 6.1. Se sugiere que a toda paciente con CEO estadios III/IV avanzado o metastásico, con estatus de desempeño (performance score care - PSC) de 0-2 se le administre como tratamiento estándar quimioterapia intravenosa (IV) adyuvante dentro de las seis semanas posteriores a la Cpr. Se sugiere administrar paclitaxel/carboplatino. 6.2. Se sugiere utilizar quimioterapia estándar basada en platino más bevacizumab como adyuvancia en pacientes con enfermedad de alto riesgo (CEO estadios IV o III con citorreducción tumoral subóptima), continuando con bevacizumab como mantenimiento. No se recomienda el uso de bevacizumab como terapia de mantenimiento si no se incluyó en la primera línea de tratamiento. Se sugiere seguir los esquemas de los estudios Gynecologic Oncology Group Study (GOG-0218) e International Collaborative Ovarian Neoplasm (ICON7). 6.3. Se sugiere la quimioterapia combinada IV/intraperitoneal (IP) solo para pacientes seleccionadas, con una citorreducción óptima (lesiones residuales < 1 cm), en especial aquellas sin enfermedad residual (R0) y que sean evaluadas en junta multidisciplinaria. La quimioterapia combinada IV/IP no se considera como tratamiento estándar. 6.4. 6.4.1. Se sugiere utilizar inhibidores de poli(ADP-ribosa) polimerasa (PARP) tales como olaparib o niraparib como mantenimiento después de recibir una primera línea de quimioterapia en pacientes con CEO estadios III/IV BRCA1/2 positivo que recibieron quimioterapia basada en platino y obtuvieron respuesta completa/respuesta parcial (RC/RP). 6.4.2. Se sugiere utilizar olaparib solo o en combinación con bevacizumab o niraparib en pacientes con CEO estadios III/IV BRCA1/2 positivo que recibieron quimioterapia basada en platino más bevacizumab y obtuvieron RC/RP. 6.4.3. Se sugiere utilizar niraparib en pacientes con CEO estadio III/IV BRCA1/2 negativo o desconocido que recibieron quimioterapia basada en platino y obtuvieron RC/RP. 6.4.4. Se sugiere utilizar bevacizumab u olaparib más bevacizumab en pacientes con CEO estadios III/IV BRCA1/2 negativo o desconocido (HRD positivo) que recibieron quimioterapia basada en platino más bevacizumab y obtuvieron RC/RP. Tratamiento de la recaída de la enfermedad Recomendación 7. Se sugiere la realización de la cirugía de citorreducción secundaria (Csec), seguida de quimioterapia, a pacientes seleccionadas con CEO de alto grado avanzado o metastásico en primera recaída, platino-sensibles (intervalo libre de platinos ≥ 6 meses), puntuación Arbeitsgemeinschaft Gynäkologische Onkologie (AGO) positiva o Integrate model (I-Model) positivo (< 4,7), y con una potencial resección a R0, en centros con acceso a soporte quirúrgico y posoperatorio óptimo. Nota: el intervalo libre de tratamiento con platinos y la puntuación AGO solo se han desarrollado como predictores positivos de resección completa y no para excluir a las pacientes de la cirugía. Recomendación 8 8.1. Para pacientes con CEO de alto grado avanzado o metastásico en recaída platino-sensibles se sugiere: Quimioterapia combinada basada en platino: carboplatino/doxorrubicina liposomal o carboplatino/paclitaxel o carboplatino/ nab-paclitaxel o carboplatino/docetaxel o carboplatino/gemcitabina, por seis ciclos. Si no se tolera la terapia combinada, dar carboplatino o cisplatino solo. Quimioterapia combinada: carboplatino/gemcitabina o carboplatino/paclitaxel o carboplatino/doxorubicina liposomal, más bevacizumab, seguida de bevacizumab como mantenimiento (hasta progresión o toxicidad). 8.2. Para pacientes con CEO de alto grado avanzado o metastásico en recaída, platino-resistentes, se sugiere: Tratamiento secuencial con quimioterapia, preferiblemente con un agente único que no sea un platino (paclitaxel semanal o doxorrubicina liposomal pegilada o docetaxel o etopósido oral o gemcitabina o trabectidina o topotecan). El paclitaxel semanal o la doxorrubicina liposomal pegilada o el topotecan pueden ser administrados con o sin bevacizumab. Existen otros agentes que se consideran potencialmente act ivos (capecitabina, ciclofosfamida, ifosfamida, irinotecán, oxaliplatino, pemetrexed, vinorelbina, ciclofosfamida), que se podrían recomendar para líneas posteriores. Las pacientes con receptores hormonales positivos que no toleran o no tienen respuesta a los regímenes citotóxicos pueden recibir terapia hormonal con tamoxifeno u otros agentes, incluidos los inhibidores de la aromatasa (anastrozol y letrozol) o acetato de leuprolide o acetato de megestrol. Pacientes con PSC ≥ 3 deberían ser consideradas solo para el mejor cuidado de soporte. 8.3. Terapia de mantenimiento con inhibidores PARP. Para pacientes con CEO de alto grado avanzado o metastásico en recaída estadios III/IV BRCA1/2 (positivo, negativo o desconocido), que hayan recibido dos o más líneas de quimioterapia basada en platino y hayan alcanzado RC/RP, se sugiere utilizar olaparib, niraparib o rucaparib. El niraparib podría ser útil en pacientes BRCA 1/2 +/-/desconocido, al igual que el rucaparib, sin embargo, este último no tiene aún aprobación del ente regulador en Colombia. Conclusiones: se espera que las recomendaciones emitidas en este consenso contribuyan a mejorar la atención clínica, el impacto oncológico y la calidad de vida de estas mujeres.

Partnering Early to Provide for Infants At Risk of Cerebral Palsy (PEPI ARC): protocol for a feasibility study of a regional hub for early detection of cerebral palsy in Aotearoa New Zealand.

Introduction: Cerebral palsy (CP) can now be diagnosed in infants with identified CP risk factors as early as three months of age; however, many barriers prevent equitable access to early detection pathways. The "Partnering Early to Provide for Infants At Risk of Cerebral Palsy" feasibility study (PEPI ARC) seeks to trial a new approach to decrease inequitable health service in Aotearoa New Zealand for high-risk infants and their families. PEPI ARC incorporates face-to-face clinics, an in-person and virtual Hub, and the use of telehealth to enable flexible access to CP assessments and support for health professionals in early CP detection. Methods and analysis: A non-randomised feasibility study was conducted from a tertiary Neonatal Intensive Care Unit (NICU) in Wellington and included seven regional referral centres, servicing nearly 30% of the total population in New Zealand (NZ). The families of infants with a high risk of neurodevelopmental impairment and health professionals interacting with the Hub were invited to participate. Mixed methods were used to evaluate the (i) equitable implementation of an early detection pathway, (ii) acceptability, (iii) demand among families and health professionals, (iv) efficacy in relation to reducing the age of receipt of CP diagnosis, and (v) the experiences around communication and information sharing. Ethics and dissemination: The NZ Health and Disability Ethics Committee approved this study (HDEC: 2022 FULL 13434). The findings will be disseminated in peer-reviewed journals, in conference presentations, and via professional networks. Clinical trial registration: Australian New Zealand Clinical Trials Registry: ACTRN12623000600640.

A prospective assessment of readiness to implement an early detection of cerebral palsy pathway in a neonatal intensive care setting using the PARIHS framework.

BACKGROUND: Early detection of cerebral palsy (CP) is possible through targeted use of assessment tools. Changes in practice are needed to facilitate this shift towards earlier diagnosis of CP in New Zealand. The aim of this study was to prospectively evaluate readiness to implement an early detection of CP pathway within a level 3 neonatal intensive care unit (NICU) setting prior to any implementation taking place. The PARIHS (Promoting Action on Research Implementation in Health Services) framework was engaged to assess readiness by highlighting determinants that influence implementation outcomes as either barriers or enablers. METHODS: A mixed methods approach was used. Firstly, an online staff survey assessed PARIHS sub-elements using Likert scores and free text with the intent to develop a baseline understanding of staff views. Secondly, focus groups were conducted to gain deeper understanding of barriers and enablers to implementation. Participants included health professionals involved in the first 6 months of life. Data were analysed to outline the barriers and enablers of implementation under the Evidence and Context constructs of the PARIHS framework. RESULTS: Twenty-seven participants completed the survey, and 20 participants participated in eight focus groups and two individual interviews. Quantitative (survey) findings found 65% agreement around the usefulness of research evidence on early CP detection; however, ≤ 45% felt current resources (i.e. human, financial and IT) were sufficient for implementation. Qualitative findings (survey and focus groups) highlighted key staff concerns around resources, family impact (creating unnecessary stress), and equity (barriers to participation). Staff wanted information regarding how international evidence translates to the local context and availability of timely follow-up services. Sub-elements within the Evidence and Context constructs were rated as either mixed or low (except for Evidence - Research, rated as high), overall indicating that Auckland NICU is at the early stages of readiness to implement the early CP detection pathway. CONCLUSION: This work may resonate with other neonatal services preparing to implement CP early detection pathways. Resourcing has a major role in facilitating implementation of pathways and uncertainty about resources is a barrier to implementation. Ongoing focus on building consensus and funding is required to ensure optimal uptake.

Alternative management for gynecological cancer care during the COVID-2019 pandemic: A Latin American survey.

OBJECTIVE: To determine the acceptance rate of treatment alternatives for women with either preinvasive conditions or gynecologic cancers during the COVID-19 pandemic among Latin American gynecological cancer specialists. METHODS: Twelve experts in gynecological cancer designed an electronic survey, according to recommendations from international societies, using an online platform. The survey included 22 questions on five topics: consultation care, preinvasive cervical pathology, and cervical, ovarian, and endometrial cancer. The questionnaire was distributed to 1052 specialists in 14 Latin American countries. A descriptive analysis was carried out using statistical software. RESULTS: A total of 610 responses were received, for an overall response rate of 58.0%. Respondents favored offering teleconsultation as triage for post-cancer treatment follow-up (94.6%), neoadjuvant chemotherapy in advanced stage epithelial ovarian cancer (95.6%), and total hysterectomy with bilateral salpingo-oophorectomy and defining adjuvant treatment with histopathological features in early stage endometrial cancer (85.4%). Other questions showed agreement rates of over 64%, except for review of pathology results in person and use of upfront concurrent chemoradiation for early stage cervical cancer (disagreement 56.4% and 58.9%, respectively). CONCLUSION: Latin American specialists accepted some alternative management strategies for gynecological cancer care during the COVID-19 pandemic, which may reflect the region's particularities. The COVID-19 pandemic led Latin American specialists to accept alternative management strategies for gynecological cancer care, especially regarding surgical decisions.

Early identification of infants at risk of cerebral palsy: developing the use of general movement assessment in routine clinical practice in a tertiary neonatal unit in New Zealand.

BACKGROUND: Preterm infants have a high risk of neurodevelopmental disability, including cerebral palsy (CP). Often, CP is not diagnosed until after 12 months, leading to delay in targeted interventions. The General Movements assessment (GM) evaluates the spontaneous movements of high-risk infants from birth to 20 weeks corrected postnatal age (CPA), and accurately predicts the risk of CP. This allows for earlier diagnosis and intervention, potentially changing the trajectory of disability, yet routine use of GM is not well established in New Zealand. AIM: To describe the process of setting up GM in a tertiary neonatal unit. METHODS: We reviewed the process and progress made to date setting up GM in our service. RESULTS: Challenges and potential solutions for the implementation of GM were identified. Key areas of development included staff training and support, IT services, resources, medical documentation, inter-departmental communication and establishing clinical pathways. CONCLUSION: GM has become successfully integrated into the assessment of high-risk infants in our neonatal unit, with the aim to provide valuable information to health professionals and families to optimise intervention and improve outcomes. Efforts will continue to ensure there is robust and sustainable system for using GM in our service.

Papel de la linfadenectomía paraaórtica inframesentérica durante la histerectomía radical en pacientes con cáncer cervical estadio IB1 en el Instituto Nacional de Cancerología Bogotá, Colombia / Role of inframesenteric para-aortic lymphadenectomy during radical hysterectomy in patients with IB1 cervical cancer in Instituto Nacional de Cancerología Bogota, Colombia

INTRODUCCIÓN: El cáncer cervical es una patología común en países en vías de desarrollo. La histerectomía radical es el estándar de manejo en estadios tempranos sin deseo de fertilidad. La linfadenectomía paraaórtica como parte del tratamiento quirúrgico es controversial. El objetivo de este estudio es determinar la frecuencia de compromiso ganglionar paraaórtico en una serie retrospectiva de pacientes con carcinoma cervical estadio IB1 (clasificación FIGO 2009) llevadas a histerectomía radical mas linfadenectomía pélvica y paraaórtica en el Instituto Nacional de Cancerología durante el periodo de enero 1 de 2009 a marzo 31 de 2017. MÉTODOS: Estudio descriptivo, retrospectivo. Se describieron variables clínicas, operatorias e histopatológicas. Se determinó la frecuencia de compromiso ganglionar a nivel paraaórtico o pélvico, y concurrente. Se realizó análisis univariado en el software estadístico R Project versión 3.6.0. RESULTADOS: Se incluyeron 88 casos. El promedio de edad fue 44,24 ± 9,99 años. La mediana del número de ganglios pélvicos y paraaórticos resecados fue de 23 (6-68) y 4 (1-25), respectivamente. En el 12,5% de las pacientes se observó compromiso tumoral ganglionar pélvico. No se detectó compromiso metastásico de ganglios paraórticos en ningún caso. Dos pacientes presentaron recaída ganglionar paraaórtica durante el seguimiento, recibiendo tratamiento con quimioterapia y quimiorradioterapia de campo extendido, respectivamente. CONCLUSIÓN: En este estudio no se detectó compromiso paraaórtico en pacientes con cáncer cervical IB1 sometidas a histerectomía radical. Este resultado se debe considerar al ofrecer linfadenectomía paraaórtica en pacientes con ganglios pélvicos aparentemente normales en el acto operatorio y/o en los estudios de imágenes prequirúrgicas.

INTRODUCTION: Cervical cancer is a common pathology in developing countries. Radical hysterectomy is the standard of management in early stages without desire for fertility. Paraaortic lymphadenectomy as part of surgical treatment is controversial. The objective of this study is to determine the frequency of paraaortic lymph node involvement in a retrospective series of patients with stage IB1 cervical carcinoma (FIGO 2009 classification) underwent to radical hysterectomy plus pelvic and paraaortic lymphadenectomy at the Instituto Nacional de Cancerologia during the period of January 1 2009 to March 31 2017. METHODS: Descriptive, retrospective study. Clinical, operative, and histopathological variables were described. The frequency of paraaortic, pelvic, concurrent lymph node involvement and adjuvant treatment was determined. A univariate analysis of the variables was performed in the R project statistical software version 3.6.0. RESULTS: 88 cases were included. The mean age was 44,24 ± 9,99 years. The median number of resected pelvic and para-aortic nodes was 23 (6-68) and 4 (1-25), respectively. In 12,5 % of the patients, involvement of the pelvic lymph nodes was present. No patient had paraaortic lymph node involvement. Two patients presented para-aortic lymph node relapse during follow-up, receiving treatment with chemotherapy and extended field chemoradiotherapy, respectively. CONCLUSION: In this study, the frequency of paraaortic involvement in patients with cervical cancer IB1 was 0%. This result should be considered when offering paraaortic lymphadenectomy in patients with apparently normal pelvic nodes in presurgical imaging studies and during the procedure.

Concordancia de lectura de test de ejercicio cardiopulmonar integrado utilizando un protocolo estándar en una población con antecedente de trauma de guerra / Concordance of integrated cardiopulmonary exercise testing interpretations using a standard protocol in a population with a background of war trauma

El test de ejercicio cardiopulmonar evalúa la tolerancia al ejercicio y provee una evaluación integral del sistema respiratorio, cardiovascular y muscular siendo útil en el diagnóstico diferencial de alteraciones cardiopulmonares específicas con desórdenes psicológicos o simulaciones, sin embargo, pueden existir diferencias en su interp Objetivo: evaluar el grado de concordancia interobservador para la interpretación del test de ejercicio cardiopulmonar utilizando el algoritmo diagnóstico de K. Wasserman en una población de pacientes jóvenes con heridas en combate. Materiales y métodos: estudio de concordancia en la interpretación de 33 test de ejercicio cardiopulmonar por tres observadores y dos porgramas computalizados. El análisis se realizó primero entre los resultados de cada una de las observaciones con el diagnóstico final dado por consenso de los observadores y luego se realizó un análisis interobservador con los diferentes diagnósticos a los cual se puede llegar mediante el test utilizando el coeficiente kappa, considerándose estadísticamente significativo una p<0,05. Resultados: las mejores concordancia entre observadores y el diagnóstico final fueron observadas bajo las categorías de normal y anormal, kappa con fuerza de concordancia de débil a buena (0,2725 - 06959 con p<0,05). Cuando los diagnósticos son más específicos los valores kappa disminuyeron. La mejor concordancia entre los observadores se encontró cuando se comparan entre diagnósticos específicos, con coeficientes kappa mas altos para el diagnostico de enfermedades pulmonares. Conclusión: el algoritmo diagnóstico utilizado para la interpretación de los test de ejercicio cardiopulmonar tiene bajos coeficientes de concordancia en general en esta población requiriendo para la misma un adecuado enfoque con historia clínica con algoritmos diagnósticos validados que pueden ser complementados con programas de computador específicos.
