Core Tip

Core tip: Tumor size and grade were the most significantly associated factors, and tumor size was the sole factor that was independently related to survival in a multivariate analysis. Patients with tumors larger than 2 cm had a ten-fold higher risk of death. Patients with advanced neuroendocrine carcinomas had a significantly decreased 5-year overall survival compared to patients with grades 1 and 2 disease.
