Carcinoide gastrointestinal. Experiencia de siete años en el Instituto Nacional del Cáncer (2000-2006)

Abstract

Background: The incidence of carcinoid tumors (CT) has increased in the last five decades. These supposedly benign tumors may not always behave as such. The largest series of CT show that the most common primary tumor site (appendiceal) changed over the years. Aim: To evaluate the management of gastrointestinal CT at the National Cancer Institute from 2000 to 2006, describe their anatomic location and estimate disease specific survival. Material and Methods: Review of the database of the Cancer Committee, during a period of 7 years, looking for patients with a pathological diagnosis of CT, whose clinical records were analyzed. Results: The records of 25 patients with gastrointestinal CT, aged 18 to 79 years (19 females) were analyzed. Five years disease specific survival was 91.1%. The most common location was appendiceal in 56% of cases, with a 5 years disease specific survival of 100%. Right hemicolectomy was performed in seven patients with appendiceal carcinoid. Other seven patients only underwent appendectomy. Five years disease specific survival was 100% in both groups. Conclusions: The appendix is still the most common location of CT in this series and long term survival is acceptable.
