RESUMO

Introduction: Intussusceptions in adults are rare, representing 1% to 5% of intestinal obstructions in this age group. This condition can be caused by benign and malignant lesions acting as lead points, the latter being the most frequent. Furthermore, the diagnosis is challenging due to the non-specific symptoms with variable duration. Case Presentation: A 43-year-old man, with a history of localized clear-cell renal carcinoma (ccRCC) treated 9 years earlier with a right radical nephrectomy, presented with bowel obstruction symptoms. An abdominal computed tomography scan showed an ileocolonic intussusception. Hence, the patient required a right hemicolectomy with ileotransverse anastomosis. The histopathological analysis showed a metastatic ccRC to the terminal ileum causing the intussusception. Discussion: Adult intussusceptions are rare. However, they should be considered in the differential diagnosis of patients with abdominal pain and symptoms of bowel obstruction. Metastases of renal cancer to the small bowel are uncommon and even more so in the form of intussusception. Definitive treatment must be tailored to the patient's condition and underlying cause.

RESUMO

Introducción: el carcinoma renal de células claras (CRCC) es el más común de los cánceres del riñón, al tiempo del diagnóstico un 30% de pacientes presenta metástasis y un 40% se encuentra en recurrencia de la enfermedad. Es altamente resistente al tratamiento de quimioterapia y se ha evidenciado pobres respuestas con las interleuquinas e interferón antes utilizados, por lo que actualmente la terapia blanco con inhibidores de la tirosina quinasa son utilizados. Este estudio tiene como objetivo establecer la sobrevida global y el tiempo de progresión en pacientes con CRCC metastásico tratados con Sunitinib. Materiales y métodos: estudio clínico de cohorte analítico retrospectivo, con análisis de supervivencia mediante la técnica de Kaplan Meier. Se revisan las historias clínicas de 42 pacientes con diagnóstico de cáncer renal de células claras (CRCC) metastásico tratados con el inhibidor de tirosin quinasa Sunitinib en el servicio de Oncología del Hospital Carlos Andrade Marín durante el período comprendido entre el primero de enero de 2010 y 31 de diciembre de 2012 para obtener variables clínicas y realizar análisis de supervivencia. Resultados: 42 pacientes analizados con cáncer renal metastásico de células claras, 22 de ellos recibieron tratamiento con Sunitinib y 20 no recibieron este tratamiento, encontrando que la mediana de sobrevida para el grupo de pacientes tratados con Sunitinib fue de 16 meses versus 4,5 meses para los pacientes que no recibieron. La mediana del tiempo de progresión en el grupo de Sunitinib fue de 6 meses. Conclusiones: los resultados del análisis de tiempo de progresión en los pacientes tratados con Sunitinib fue similar a los estudios de referencia y guías de manejo oncológicos internacionales. En términos de sobrevida se obtuvo un resultado favorable sin embargo, los resultados aún no son concluyentes.


Introduction: the clear cell renal cell carcinoma (CRCC) is the most common cancer of the kidney, at the time of diagnosis 30% of patients have metastases and 40% are in disease recurrence. It is highly resistant to chemotherapy and poor responses were evidenced with the interleukins and interferon before use, so that the current target therapy with tyrosine kinase inhibitors were used. The objective of this study is to determine the survival and time to progression in patients with metastatic CRCC treated with Sunitinib. Materials and methods: retrospective study by Kaplan Meier technique, using the statistical package Epi Info 3.5, in patients with metastatic CRCC evaluated in the oncology department in the period between january 2010 and december 2012. Results: 42 patients with CRCC clear cell were analyzed, 22 of them were treated with Sunitinib and 20 did not receive this treatment. Findings show that the median survival for the group of patients treated with Sunitinib was 16 months versus 4.5 months for patients who did not. The median time to progression in the Sunitinib was 6 months. Conclusions: the results of the analysis of time of progression in patients treated with Sunitinib were similar at baseline and according to international oncology management guidelines. Favorable results were obtained in terms of survival; however results still are inconclusive.
