Outcome and prognostic factors in bronchial carcinoids: a single-center experience.

Abstract INTRODUCTION: The aim of this study is to assess factors influencing survival in patients with bronchial carcinoids (BCs). METHODS: A retrospective review of our surgical database of patients operated for primary lung cancer with a final histologic diagnosis of BC in the period from January 1, 1995 to December 31, 2010 was carried out. RESULTS: There were 126 patients (74 women): 83 had a typical carcinoid and 43 an atypical one (AC). All patients received a radical resection; systematic lymphadenectomy was accomplished in 120. Lymph nodal metastases were observed in 26 cases (12 N2) and were more frequent in ACs (p = 0.009). Twelve patients received adjuvant therapy (chemo/radio/biological). Distant metastases (DM) and local tumor recurrence occurred in 28 (22%) and 8 (6.3%) cases, respectively: DM were more frequent in ACs (p = 0.0001) and in N2 patients (p = 0.0001). Smoke, atypical histology, lymph nodal metastases, and high cellular proliferative index demonstrated to be statistically negative prognostic factors. CONCLUSION: Even if characterized by an indolent behavior, BCs may spread to lymph node or distant or present with local recurrence. Amid all prognostic factors, the presence of DM demonstrated to be the strongest negative one.
