RESUMO

Objetivo Evaluar las posibilidades de rescate tras la recidiva local en pacientes con carcinomas de orofaringe tratados con radioterapia y analizar los factores pronósticos relacionados con el control final de la enfermedad. Métodos Estudio retrospectivo de 596 con carcinomas de orofaringe pacientes tratados con radioterapia durante el periodo 1991-2018. Resultados Ciento ochenta y un pacientes (30,4%) tuvieron una recidiva local. De los pacientes con una recidiva local, 51 (28,2%) fueron tratados con una cirugía de rescate. Las variables que se relacionaron con que el paciente no recibiese una cirugía de rescate fueron una edad superior a los 75 años, la localización del tumor en la pared posterior de la hipofaringe, una extensión inicial del tumor cT4 y un intervalo libre de recidiva inferior a los 6 meses. La supervivencia específica a los 5 años de los pacientes tratados con una cirugía de rescate fue del 19,1% (IC del 95%: 7,3-30,9%). Las variables que se relacionaron con la supervivencia específica fueron la extensión de la recidiva y el estatus de los márgenes de resección. No se consiguió el control final del tumor en ninguno de los pacientes con una recidiva extensa (rpT3-4, n=25) o con unos márgenes de resección positivos (n=22). Conclusión Los pacientes con carcinomas de orofaringe tratados con radioterapia con una recidiva local del tumor cuentan con un pronóstico limitado. Una mayoría de los pacientes (71,8%) no fueron considerados candidatos a cirugía de rescate. La supervivencia específica a los 5 años de los pacientes tratados con una cirugía de rescate fue del 19,1%. (AU)


Objective To evaluate the possibilities of salvage after local recurrence in patients with oropharyngeal carcinomas treated with radiotherapy, and to analyze the prognostic factors related to the final control of the disease. Methods Retrospective study of 596 patients with oropharyngeal carcinoma treated with radiotherapy during the period 1991–2018. Results One hundred and eighty-one patients (30.4%) had a local recurrence. Of the patients with a local recurrence, 51 (28.2%) were treated with salvage surgery. Variables that were associated with the patient not receiving salvage surgery were age greater than 75 years, tumor location in the posterior hypopharyngeal wall, an initial tumor extent cT4, and a recurrence-free interval of less than 6 months. Five-year specific survival of patients treated with salvage surgery was 19.1% (95% CI: 7.3%–30.9%). Variables that were related to specific survival were extent of recurrence and status of resection margins. Final tumor control was not achieved in any of the patients with extensive recurrence (rpT3-4, n=25) or positive resection margins (n=22). Conclusion Patients with oropharyngeal carcinomas treated with radiotherapy with local tumor recurrence have a limited prognosis. Most patients (71.8%) were not considered candidates for salvage surgery. The 5-year specific survival of patients treated with salvage surgery was 19.1%. (AU)

RESUMO

Objetivos: Analizar la supervivencia en el grupo de pacientes con gliomas de alto grado tratados de forma consecutiva en un mismo centro a lo largo de 10 años. Establecer la relevancia de los factores asociados y el papel de la cirugía de rescate en el momento de la progresión.MétodosFueron analizados de forma retrospectiva los pacientes con gliomas grado III y IV de la Organización Mundial de la Salud (OMS) diagnosticados en el Hospital Gregorio Marañón desde el 1 de enero de 2008 hasta el 31 de diciembre de 2017. Se obtuvieron de la historia clínica los datos clínicos, radiológicos y anatomopatológicos.ResultadosSe completó el seguimiento en 233 pacientes con diagnóstico de glioma de alto grado (III o IV de la OMS). La edad media fue de 62,2 años. La mediana de supervivencia se situó en 15,4 meses. De los 133 pacientes (59,6%) que habían sido intervenidos mediante cirugía resectiva en el momento del diagnóstico, en 43 (32,3%) se efectuó cirugía de rescate en el momento de la progresión. La supervivencia global, así como la supervivencia tras la progresión, resultó mayor en este subgrupo de pacientes. Otras variables relacionadas con una mayor supervivencia fueron la puntuación en la escala de Karnofsky, el grado de resección quirúrgica y el diagnóstico inicial de grado III de la OMS.ConclusionesAlrededor de una tercera parte de los pacientes con gliomas de alto grado pueden ser candidatos a una cirugía de rescate en el momento de la progresión. Ello está asociado a una mayor supervivencia. (AU)

RESUMO

Local excision (LE) has arisen as an alternative to total mesorectal excision for the treatment of early rectal cancer. Despite a decreased morbidity, there are still concerns about LE outcomes. This systematic-review and meta-analysis design is based on the "PICO" process, aiming to answer to three questions related to LE as primary treatment for early-rectal cancer, the optimal method for LE, and the potential role for completion treatment in high-risk histology tumors and outcomes of salvage surgery. The results revealed that reported overall survival (OS) and disease-specific survival (DSS) were 71%-91.7% and 80%-94% for LE, in contrast to 92.3%-94.3% and 94.4%-97% for radical surgery. Additional analysis of National Database studies revealed lower OS with LE (HR: 1.26; 95%CI, 1.09-1.45) and DSS (HR: 1.19; 95%CI, 1.01-1.41) after LE. Furthermore, patients receiving LE were significantly more prone develop local recurrence (RR: 3.44, 95%CI, 2.50-4.74). Analysis of available transanal surgical platforms was performed, finding no significant differences among them but reduced local recurrence compared to traditional transanal LE (OR:0.24;95%CI, 0.15-0.4). Finally, we found poor survival outcomes for patients undergoing salvage surgery, favoring completion treatment (chemoradiotherapy or surgery) when high-risk histology is present. In conclusion, LE could be considered adequate provided a full-thickness specimen can be achieved that the patient is informed about risk for potential requirement of completion treatment. Early-rectal cancer cases should be discussed in a multidisciplinary team, and patient's preferences must be considered in the decision-making process.

RESUMO

INTRODUCCIÓN: Este documento técnico se realiza a solicitud del Instituto Nacional de Ciencias Neurológicas. Cuadro clínico: El accidente cerebral vascular (ACV) se define como los síntomas y signos de compromiso neurológico focal, de inicio brusco, que llevan a la muerte o que duran más de 24 horas y que no pueden ser atribuibles a otra causa aparente que la vascular. Los pacientes con ACV por oclusión aguda de la ACI no han sido tradicionalmente candidatos a una revascularización carotídea mediante la implantación de un stent con o sin angioplastia, sin embargo, nuevos estudios indican que el tratamiento endovascular de la oclusión aguda de la ACI es factible, seguro y puede mejorar el pronóstico funcional de estos pacientes. Tecnología sanitária: La cirugía como tratamiento de rescate en ACV consiste en el tratamiento endovascular (TEV) que puede incluir la fibrinolisis arterial, la trombólisis mecánica (TM) y la endarterectomía de la estenosis u oclusión de la ACI. Para minimizar los retrasos en el inicio del tratamiento, se han diseñado estrategias que combinan la rapidez de administración de la trombólisis IV con la eficacia de la trombólisis intraarterial. Esta estrategia, denominada de rescate, beneficiaría principalmente a aquellos pacientes con escasas probabilidad de respuesta a la trombólisis endovenosa OBJETIVO: Evaluar la eficacia y seguridad, así como documentos relacionados a la decisión de cobertura de la cirugía de rescate vascular en el tratamiento de pacientes con Infarto cerebral agudo por oclusión de vaso de arteria carótida interna. METODOLOGÍA: Se realizó una búsqueda en las principales bases de datos bibliográficas: MEDLINE, LILACS, COCHRANE, así como en buscadores genéricos de Internet incluyendo Google Scholar y TRIPDATABASE. Adicionalmente, se hizo una búsqueda dentro de la información generada por las principales instituciones internacionales de cirugía vascular, y agencias de tecnologías sanitarias que realizan revisiones sistemáticas (RS), evaluación de tecnologías sanitarias (ETS) y guías de práctica clínica (GPC). RESULTADOS: Se identificaron una RS, cinco GPC y una ETS. Adicionalmente se seleccionaron dos estudios observacionales. No se encontraron evaluaciones económicas de Perú o la región latinoamericana. CONCLUSIONES: La evidencia con respecto a la cirugía de rescate vascular en el tratamiento de pacientes con infarto cerebral agudo por oclusión de vaso de arteria carótida interna es escaso. Basado en una revisión sistemática, se muestra un beneficio en la mortalidad de este procedimiento comparado a manejo no quirúrgico especialmente en manejo de vasos grandes. Sin embargo, los resultados podrían referir que no hay un beneficio diferencial con respecto a hemorragias intracraneales. Basado en estudios observacionales la tecnología se muestra como eficaz y segura sin embargo estos resultados no son comparativos por lo que es importante ponerlos en contexto. Las GPC y ETS recabadas mencionan a la tecnología de interés para el manejo de ACV de grandes vasos después del fracaso o contraindicación de trombólisis.

RESUMO

La recurrencia de carcinoma de células escamosas orofaríngeo (CCEOF) se asocia a mal pronóstico, particularmente en recurrencias en etapa avanzada. La cirugía en el contexto de rescate es más complicada por el tratamiento oncológico del tumor primario, por lo tanto, tiene un mayor riesgo de complicaciones y estadía hospitalaria. Sin embargo, la cirugía de rescate es la mejor oportunidad del paciente como tratamiento curativo y para supervivencia a largo plazo. La población de pacientes que reciben tratamiento para CCEOF ha cambiado en la última década, se ha reconocido que la incidencia de virus papiloma humano (VPH) asociado a CCEOF ha generado el gran aumento de CCEOF y el cambio asociado en las características de la población de pacientes, ahora los pacientes son más jóvenes y tienen menos comorbilidades. Con el aumento exponencial en la incidencia de CCEOF, la necesidad de cirugía de rescate en CCEOF podría verse en aumento. En vista del aumento de la incidencia de casos con carcinoma escamoso de orofaringe y su importante relación con el VPH, esta revisión se enfoca en la supervivencia tras cirugía de rescate con intención curativa y evaluar si con los avances en su tratamiento ha mejorado su pronóstico.


Recurrence of oropharyngeal squamous cell carcinoma (OPSCC) is associated with poor prognosis, particularly in advanced stage recurrences. Salvage surgery is complicated by previous oncological treatment of the primary tumor, therefore, it has a higher risk of complications and hospital stay. However, salvage surgery is the patient's best opportunity as a curative treatment and for long-term survival. The population of patients receiving treatment for OPSCC has changed in the last decade, it has been recognized that the incidence of human papilloma virus (HPV) associated OPSCC has generated an increase of OPSCC and changes in the epidemiology of the patient population, with younger patients and with less comorbidities. With the exponential increase in the incidence of OPSCC, the need for salvage surgery in OPSCC could increase in the future. In view of the increase in the incidence of cases with squamous oropharyngeal carcinoma and its relationship with HPV, this review focuses on survival after salvage surgery with curative intent and assessing whether the progress in its treatment has improved its prognosis.

RESUMO

OBJECTIVE: To analyse the oncological results of a salvage total laryngectomy in patients with a laryngeal carcinoma. MATERIAL AND METHODS: Retrospective review of a cohort of 241 patients treated with a salvage laryngectomy after a local recurrence. The initial treatment received by these patients was radiotherapy (n=201, 83.4%), chemoradiotherapy (n=19, 7.9%), and partial surgery (n=21, 8.7%), RESULTS: Total laryngectomy as salvage treatment achieved local control of the disease in 81.3% of cases, with a 5-year specific survival of 65.3%. The variables related with specific survival in a univariate analysis were the location of the primary tumour, the local extension of the initial tumour and of the recurrence, the resection margins, and the pathological status of the neck dissections. According to the results of a multivariate analysis, the variables related to specific survival were the status of the resection margins, the presence of simultaneous regional recurrence, and the local extension of the recurrence. CONCLUSION: The 5-year specific survival of patients treated with a salvage laryngectomy was 65.3%. The variables related with the control of the disease were the status of the resection margins, the presence of simultaneous regional recurrence and the local extension of the recurrence.

RESUMO

Se efectuó un simulacro de amputación de necesidad y rescate en dependencias de la Base Marambio (Antártida Argentina). La amputación de una extremidad constituye un dilema al cual está sujeto un médico en determinadas situaciones críticas. Además, los intentos infructuosos para salvar una extremidad irrecuperable están asociados a una alta morbilidad y muchas veces son letales para el paciente. Existen innumerables discusiones en relación con los criterios de predicción para conservar un miembro lesionado, por lo que se han propuesto varios índices de valoración para determinar qué extremidad puede ser conservada o cuál amputada. Por ello en el presente trabajo se efectúa una revisión bibliográfica sobre el uso de tablas y/o criterios para la toma de tal decisión. Se efectuó un ejercicio simulado en el cual se consideró la escena (situación de aislamiento geográfico, características inhóspitas y recursos limitados en la Antártida) y el estado de atrapamiento de la víctima, más la irrecuperabilidad de la porción distal del miembro superior, en donde debía priorizarse la vida del paciente, respecto a la pérdida de la extremidad que ya se encontraba mutilada en forma irreversible, con el fin de ser estabilizado y extricado del lugar para ser trasladado a otro espacio para completar con mejores medios su tratamiento definitivo. Dicho ejercicio se realizó como parte de la capacitación continua del personal que se desempeña en las Bases Antárticas, que dadas las características del escenario antártico, hacen necesaria tal preparación para afrontar situaciones de extrema gravedad en un lugar inhóspito y alejado del continente.


We conducted a mock amputation and rescue agencies need the Marambio Base (Antarctica Argentina). The amputation of a limb is a dilemma which is subject to a doctor in certain critical situations. In addition, unsuccessful attempts to save a limb unrecoverable are associated with high morbidity and are often lethal to the patient. There are countIess discussions regarding prediction criteria to retain an injured limb, so that several indices have been proposed assessment to determine what can be preserved limb amputated or what, why in the present study the authors reviewed the literature on use of tables and/or criteria for making such a decision. We conducted a simulation exercise, which was considered the scene (geographical isolation, limited resources and inhospitable features in Antarctica) and the state of entrapment of the victim, plus the irrecoverable from the distal upper limb, where needed to prioritize the patient's life, about the loss of the limb that was already irreversibly mutilated, in order to be stabilized and extricated the place to be moved to a place with better ways to complete definitive treatment. This exercise was conducted as part of the continuous training of personnel working in the Antarctic Bases, that given the characteristics of the Antarctic scenario necessitates such a preparation to deal with situations of extreme gravity in an inhospitable place and away from the continent.
