Abstract
Objective To analyze the clinical and pathological features and prognostic factors of neuroendocrine carcinoma of the cervix (NECC). Methods The clinical data of 35 cases of NECC treated in Shanxi Provincial Cancer Hospital from January 2006 to May 2014 were retrospectively analyzed. Results The median age of 35 cases of NECC was 43 years old. The infection rate of human papillomavirus (HPV) 18 type was 66.7% (10/15) in 15 NECC patients who were tested with HPV. The accuracy rate of diagnosis was 14.3% (5/35) before procedure. The positive detection rate of Syn, CgA, AE1/AE3, P63 and NSE were respectively 100.0% (35/35), 80.0% (28/35), 100.0% (35/35), 34.3% (12/35) and 57.1% (20/35). The 3-year overall survival rate of 35 NECC cases was 34.29% (12/35). The age, volume of local tumor and degrees of interstitial infiltration were the main prognostic factors of patients with NECC(all P < 0.05). Conclusions NECC is easily misdiagnosed by pathomorphological examination alone, the accuracy of diagnosis could be improved by detecting neuroendocrine carcinoma markers with immunohistochemical method. The infection rate of HPV18 is higher than the others in NECC. The volume of local tumor is one of the main prognostic factors for NECC patients. Key words: Uterine cervical neoplasms; Neuroendocrine carcinoma; Prognosis
