Sarcoma de Kaposi: variedades clínicas y resultados del tratamiento local con radioterapia / Local radiation treatment of Kaposi's sarcoma: clinical varieties and treatment outcomes

Background: Kaposi's sarcoma (KS) is a rare tumor that affects mainly immunodeficient and elderly patients. Aim: To describe the features and outcomes of a cohort of patients with different types of KS treated locally with radiotherapy (RT). Patients and Methods: Retrospective review of patients with KS referred to our radiation oncology center for local treatment of symptomatic lesions that did not respond to high activity anti-retroviral therapy or chemotherapy. Results: Between January 1995 and December 2016, 20 patients with a median age of 40 years (18 males) with KS were assessed and treated with RT due to symptomatic lesions. The most common KS type was epidemic in 15 patients, followed by the classic type in three and the iatrogenic variety in two. In patients with non-epidemic varieties, SK was exclusively cutaneous, while visceral involvement was present in 46% of patients with epidemic SK. Complete response was observed in 95% of cases. Skin toxicity caused by RT was mild in all cases. Conclusions: RT may be considered as a reasonable local treatment choice in classic, iatrogenic and epidemic varieties of KS.

Recomendaciones sobre el manejo del cáncer de páncreas tipo adenocarcinoma en Latinoamérica: Reunión del Consenso del Simposio Latinoamericano de Gastroenterología Oncológica (SLAGO) y de la Asociación Ibero Latinoamericana de Terapia Radiante (ALATRO), Viña del Mar, Chile 2015 / Recommendations for the management of pancreatic cancer type adenocarcinoma: A consensus statement reached during the 2015 Latin American Symposium on Gastroenterological Oncology

Pancreatic cancer is a malignancy of great impact in developed countries and is having an increasing impact in Latin America. Incidence and mortality rates are similar for this cancer. This is an important reason to offer to the patients the best treatments available. During the Latin American Symposium of Gastroenterology Oncology (SLAGO) held in Viña del Mar, Chile, in April 2015, a multidisciplinary group of specialists in the field met to discuss about this disease. The main conclusions of this meeting, where practitioners from most of Latin American countries participated, are listed in this consensus that seek to serve as a guide for better decision making for patients with pancreatic cancer in Latin America.
