[Analysis of therapeutic result and prognostic factor in primary fallopian tube carcinoma].

OBJECTIVE: To investigate the impact of treatment modality and clinicopathologic profile on prognosis in primary fallopian tube carcinoma.

METHODS: The data of 64 cases with primary fallopian tube carcinoma treated between January 1991 and June 2006 were analyzed. The clinicopathological data were retrospectively analyzed.

RESULTS: The overall 5-year survival rate of this series was 56.3%. The overall 3- and 5-year survival rate was 84.6% and 65.4% in surgical staging group versus 58.3% and 33.3% in no surgical staging group with a significant difference between two groups (P = 0.0429; P = 0.043), which was 89.5% and 68.4% in optimal cytoreduction group versus 66.7% and 41.7% in suboptimal cytoreduction group (P = 0.0466; P = 0.0444). However, there was no significant difference in 3-year and 5-year survival rate between the group with pelvic lymphadenectomy and the group without (84.2% vs. 69.2%, P = 0.4667; 63.1% vs. 53.8%, P = 0.459), and also between the group treated using CAP/CP regimen and the group by TP regimen for chemotherapy (81.8% vs. 80.0%, P = 0.8946; 59.1% vs. 60.0% P = 0.9582). It was found that the 5-year survival was correlated with FIGO stage (III-IV vs. I - II, P = 0.0197), differentiation grade (G3 vs. G1 + G2, P = 0.003), pathologic type (other type vs. serous, P = 0.0494), lymph nodes status (positive vs. negative, P = 0.0295).

CONCLUSION: Surgical staging, optimal cytoreduction, differentiation grade, pathologic type, lymph node status are important factors influencing the 5-year survival in primary fallopian tube carcinoma. Pelvic lymphadenectomy is necessary and feasible to perform during the procedure of surgical staging and cytoreduction. CAP/CP and TP regiment are similarly effective in adjuvant chemotherapy for primary fallopian tube carcinoma.
