Primary fallopian tube carcinoma: a clinicopathological analysis of a rare entity.

Background: The aim of this study was to evaluate the clinical and pathological features of a rare tumor, primary fallopian tube carcinoma (PFTC).

Materials And Methods: We retrospectively analyzed the medical records of 26 patients who were diagnosed with PFTC at Cheil General Hospital and Women's Healthcare Center between March 1992 and November 2009.

Results: Median patient age was 54.6 (range 41-69) years, and the mean follow-up period was 59.8 (range 3-200) months. Twenty-one (80.8%) patients had one or more of the following preoperative symptoms: vaginal bleeding, abdominal pain, or a palpable mass. No patient was diagnosed with PFTC preoperatively; 17 (65.4%) patients were diagnosed as having an adnexal mass, six (23.1%) had hydrosalpinx, and three (11.5%) had coexisting endometrial pathology. In seven (26.9%) cases, PFTC was missed during the operation, so an additional surgery was later performed. Ten (38.5%) patients were in stage I, two (7.7%) in stage II, 13 (50%) in stage III, and one (3.8%) in stage IV. The serous type was histologically predominant (76.9%), and most were high grade (76.9%). The 5-year survival rate was 81.7%.

Conclusion: Primary fallopian tube carcinoma is hardly ever diagnosed preoperatively or intraoperatively due to its rarity. Our report may help surgeons by providing more information about the clinicopathological behavior of PTFC so that patients can be appropriately counseled. Further clinical studies should be performed to collect more information about this rare tumor.
