Management of treatment-naïve limited-stage small cell esophagus carcinoma.
OBJECTIVE
To identify the problems and principles of treatment decisions in treatment-naïve limited-stage small cell esophagus carcinoma (LD-SCEC).


METHODS
Clinical data from 39 patients with LD-SCEC treated in the Chinese People's Liberation Army General Hospital, Beijing, China between 2000 and 2013 were retrospectively collected with regard to pathologic characteristics, overall survival (OS), and relevant prognostic factors.


RESULTS
The median OS was 21.1 months (95% confidence interval [CI]: 12.4-29.7 months). The one-year OS was 76%, 3-year was 25%, and the 5-year OS was 8%. Depth of invasion, lymph metastasis status, and chemotherapy were independent prognostic factors. Of the 39 cases, only 38.4% (15 cases) were diagnosed as SCEC by the biopsy specimen. Eight of the 15 patients (group A) received chemotherapy and/or radiotherapy, while the remaining 7 patients (group B) and the other 24 patients (group C) received surgery as initial treatment. The one-year survival of group A was 87%, of group B was 69%, and of group C was 74% (p=0.037). The accuracy of the biopsy diagnosis influenced the treatment decisions and prognosis.


CONCLUSIONS
Small cell esophagus carcinoma is a systemic disease, with depth of invasion, lymph metastasis status, and chemotherapy as independent prognostic factors. Systemic therapy based on chemotherapy is recommended. The top priority is to improve the accuracy of diagnosis before deciding on the initial treatment option.
