title: [A clinical study of 27 cases of cervical metastatic carcinoma of unknown primary site].
abstract: OBJECTIVE
  To analyze the clinical feature of cervical metastatic carcinoma of unknown primary site (CCUP) for guiding clinical diagnosis and treatment.
  
  
  METHODS
  Twenty-seven cases of CCUP during May 2007 to September 2013 in department were analyzed retrospectively. Kaplan-Meier method and Log-rank test were used for survival analysis, multivariate analysis using the Cox regression model.
  
  
  RESULTS
  There is no significant influence among gender, age and the mass position on the median survival time. Median survival time of patients with different pathological types was statistically significant (P < 0.05). Treatment affected the median surial significantly (P < 0.05) and also was the independent prognostic factors (P < 0.05).
  
  
  CONCLUSIONS
  The early establishment of pathological type and primary focal position can improve the prognosis. Taking treatment according to pathological types can increase the patient's survival rate. Combined treatment can prolong the patient's survival time.
