ABSTRACT
Objective: to determine surgical prognostic variables from a retrospective cohort of histopathologically confirmed gastroenteropancreatic neuroendocrine tumors (GEP-NET) in Mexican subjects.Methods: consecutive patients treated for GEP-NET from 1999 through 2007 at Oncological Hospital were included. Demographic, clinical variables, disease-free survival were retrieved.
Results: forty-eight patients were included, 29 (60.4 %) female with a mean age of 54 years. Overall survival time was 43.7 months and disease-free survival was 33 months. Negative statistically significant overall survival time predictors were 2 and 3 histological types (HR 5.5. CI 2.0-21, p = 0.0001), tumor size › 2 cm (HR 8.8, CI 1 .29-75, p = 0.002), the presence of metastasis (HR 2.4, CI 1.2-9.6, p = 0.0001) and tumor resectability (HR 9.8, CI 2.9-40.2, p = 0.0001). For the disease-free period, only the histological type (2 or 3) was a negative outcome variable.
Conclusions: histological type, tumor size, the presence of metastasis, and tumor non resectability were significant survival predictors.
