Abstract

Background

Esophageal neuroendocrine carcinoma (NEC) is a rare malignant tumor. The role of surgery in resectable limited disease of esophageal NEC remains unclear. How to select a specific group of limited disease of esophageal NEC who might benefit from surgery remains to be answered.

Methods

Patients undergoing esophagectomy for resectable limited disease of esophageal NEC in our department from January 2007 to June 2015 were analyzed. TNM staging system was applied to describe those patients, and according to their different long-term prognosis after surgery, those patients were subgrouped into surgery response limited disease (SRLD) group and surgery non-response limited disease (SNRLD) group. Both univariate and multivariate analyses were applied to identify potential prognostic factors.

Results

A total of 72 patients with resectable limited disease of esophageal NEC were identified for analysis. The median survival time of those patients was 21.5 months. There was no significant survival differences among stage I, stage IIA, and stage IIB patients, but all these patients had significantly longer survival than stage III patients. Therefore, stage I, stage IIA, and stage IIB patients were aggregated together as SRLD group, and stage III patients were aggregated as SNRLD group. SRLD patients obtained significantly longer survival than SNRLD patients in both univariate analysis and multivariate analysis. Moreover, adjuvant therapy could significantly benefit SRLD patients (P = 0.004) but could not benefit SNRLD patients (P = 0.136).

Conclusions

Different responses to surgery existed in resectable limited disease of esophageal NEC indicating the need of further subgrouping for those patients. The resectable limited disease of esophageal NEC could be further subgrouped into SRLD group and SNRLD group according to the TNM staging system.
