title: Prognostic factors in FIGO stage IB-IIA small cell neuroendocrine carcinoma of the uterine cervix treated surgically: results of a multi-center retrospective Korean study.
abstract: BACKGROUND
  To determine the clinical and pathologic prognostic factors in surgically treated patients with International Federation of Gynecology and Obstetrics (FIGO) stage IB-IIA small cell neuroendocrine carcinoma of the uterine cervix (SCNEC).
  
  
  METHODS
  We retrospectively reviewed a total of 68 patients with FIGO stage IB-IIA SCNEC surgically treated from January 1997 to December 2003 in Korea.
  
  
  RESULTS
  Of the 68 patients, 43 had FIGO stage IB1 SCNEC, 15 had stage IB2, and 10 had stage IIA. Seven were treated with radical surgery alone; 11 with neoadjuvant chemotherapy (NACT) followed by radical surgery; 24 with radical surgery followed by adjuvant chemotherapy; and 26 with radical surgery followed by adjuvant radiation or chemoradiation. After a median follow-up of 44 months (range, 6-113 months), the 2-year and 5-year survival rates for all patients were 64.6% and 46.6%, respectively. Univariate and multivariate analysis showed that FIGO stage was predictive of poor prognosis. Patients who received NACT showed poorer prognosis than those who did not receive NACT. Adjuvant chemoradiation did not improve survival compared with adjuvant chemotherapy alone.
  
  
  CONCLUSIONS
  FIGO stage may act as a surrogate for factors prognostic of survival. Primary radical surgery followed by adjuvant chemotherapy is the preferred treatment modality for patients with early stage SCNEC.
