    Abstract:
    Primary fallopian tube carcinoma (PFTC) is a rare gynecological malignancy accounting 0.14-1.8% cases. The purpose of the study was to assess clinical, morphological and immunohistochemical features of PFTC. All the cases of PFTC were detected during 1980-2005. 31 cases of PFTC were analyzed as to Ki-67, HER-2 expression, estrogen receptors (ER), progesterone receptors (PR), grade and stage. 69 cases of PFTC were detected with an average age of 55, 6 years (range 21-73 years). Stage I detected in 34.2% cases, Stages II and III--32.8%, Ca in situ--10%. Among 31 patients ER were positive in 75% (n = 23), PR were positive in 46% (n = 14): ER+PR+ in 12 (38%) cases, ER+PR- in 11 (36%) cases, ER-PR+ in 2 (6%) cases, ER-PR- in 6 (19.4%) cases. Only 2 cases were HER-2 positive with ER+PR+ and ER-PR- status. Ki-67 labeling index (LI, %) values ranged from 15 to 95% (median 60) with average rate 58.03% +/- 4.08. Ki-67 LI values > or = 60% were graded as high and < 60% as low. We did not find any significant differences in Ki-67 LI values among tumors of various Receptor Status. However Ki-67 L1 > 60% was associated with poor 5-year survival (14%), vs 75% in Ki-67 L1 < 60%. Primary fallopian tube carcinoma is mainly HER-2 negative, receptor positive in 79.6%. Ki-67 rate is irrespective of ER PR status. However the level of Ki-67 (> 60%) was a significant survival prognostic factor.
