Abstract

Background: The purpose of this study were to investigate the survival rate of patients with cervical cancer who were treated at our institution and to analyse its prognostic factors.<br>Methods: One hundred twenty-two patients who underwent treatment for primary cervical cancer at Kochi Municipal Hospital between January 1996 and August 2003 (7 years 8 months) were retrospectively reviewed. There were 59 patients (48.4%) with stage 0 disease. Sixty-three patients (51.6%) had stage I-IV cervical cancer. The mean age was 56.7±15.6 years, and the median follow-up period was 31 months.<br>Results: The overall 5-year suvival rate was 96.4% and 77.1% in stage I and II, respectively. The overall 3-year survival rate was 56.3% in stage III, and the 30-month survival rate was 0% in stage IV. Among the risk factors of histologic cell type, clinical parametrial involvement, clinical vaginal involvement and pelvic lymph node metastasis, clinical parametrial involvement had the lowest p value (p=0.0717) in a multivariate Cox proportional hazards regression analysis.<br>  Multivariate analysis using the Cox proportional hazard regression model showed that among the risk factors of histologic cell type, clinical parametrial involvement, clinical vaginal involvement and pelvic lymph mode metastasts, the lowest p value (p=0.0717) was for clinical parametrial involvement.<br>Conclusion: Although there was no statistical significance comparing the prognostic factors in multivariate analysis, it was presumed that clinical parametrial involvement was the most influential factor among those which were analyzed in this study on the prognosis of patients with stage I-IV cervical cancer.
