[Surgical Resection and Prognosis of Bronchopulmonary Carcinoid]

Bronchopulmonary carcinoid (BPC) is a rare neuroendocrine tumor, the clinical studies on treatment and prognostic factors of BPC are somewhat controversial. Our purpose was to evaluate the clinical efficacy of surgery on BPC, and to analyze the prognostic factors affecting the survival of BPC.

We retrospectively collected the clinical data of patients with BPC admitted to the Chinese PLA General Hospital between January 2000 and December 2017. The Kaplan-Meier method was used to calculate the survival rate of patients and to map the survival curve. Then the effects of different factors like pathological classification, gender, age, on prognosis were compared by univariate analysis and multivariate analysis was made by Cox proportional hazard model.

A total of 98 patients had a diagnosis of BPC were included in the study. There were 41 patients with typical carcinoid (TC) and 57 patients with atypical carcinoid (AC). The 1-yr, 5-yr, and 10-yr overall survival rates of BPC were 96.9%, 80.0% and 73.6%, respectively. Univariate analysis showed age (P=0.000,1), smoking history (P=0.005), pathological subtype (P<0.000,1), T stage (P=0.000,2), TNM stage (P<0.000,1) were the prognostic factors. Multivariate analysis showed that age (P=0.005) and tumor stage (P=0.017) were independent prognostic factors.

BPC occurred more in middle-aged men. Surgery is the main treatment for lung cancer, and the overall prognosis is good. Age and TNM stage were independent risk factors for long-term survival after lung cancer surgery.
