RESUMO
Objective: To investigate the clinical features and survival factors of primary fallopian tube car-cinoma. Methods: We used Kaplan-Meier survival analysis, single factor analysis and multivariate analysis to evaluate the prognostic factors of 40 patients diagnosed with primary fallopian tube cancer. Results: The aver-age age of the patients was 51 years and all of them received surgery. There were 29 (72.5%) stage Ⅰ or Ⅱ patients, 11 stage Ⅲ or Ⅳ patients. Thirty-one (77.5%) patients were diagnosed with poorly differentiated tu-mors and 22 (55%) patients had serous adenocarcinoma. Thirty-seven patients received PAC/PC or TC che-motherapy after surgery. Six patients (15%) had recurrences within 23 to 56 months after surgery. The medi-an survival of Ⅰ～Ⅱ and Ⅲ～Ⅳ stage patients was 79 and 35 months, respectively. The total 5-year survival was 58% and 0 (P=0.005). Univariate and multivariate analysis showed that stage (Ⅰ～Ⅱ vs. Ⅲ-Ⅳ), grade (G_1+G_2 vs. G_3), residual disease after surgery (none, <1cm vs. >1cm) were significant factors affecting surviv-al. In accordance with the formula to calculate the half-life of CA125 and compare preoperative serum CA125 with the value at 3 weeks after surgery (T_(1/2)>3 week, T_(1/2)<3 week), the 5-year survival was 78% and 50%, re-spectively (P=0.036). Conclusion: Special attention should be paid to the joint screening of primary fallopian tube cancer in clinical practice in order to avoid misdiagnosis. The consecutive measurements of serum CA-125 level may have significant value as a prognostic indicator for patient survival.
