ABSTRACT
Background: Primary fallopian tube carcinoma (PFTC) is rare. Herein, we investigate the clinico- pathological characteristics and response to cytoreductive surgery & appropriate therapies for PFTC. Materials and Methods: Aretrospective observational study of 5 women with a histopathologic diagnosis of PFTC from January 2004 to Dec 2018. Results: The mean age at diagnosis was 53 years (range, 46 to 62 years), and the mean follow-up period was 51 months. All (100%) patients were postmenopausal. Eighty percent had an ECOG score of 0-1.The most common clinical presentation was nonspecific pelvic pain (100%), followed by abnormal vaginal bleeding (80%), and adnexal mass of unknown origin (40%). Three (60%) patients were assumed preoperatively as primarily in the ovary. All patients were diagnosed postoperatively; Primary optimal cytoreductive surgery was achievable in 4/4 (100%) in advanced disease. Only 1 (20%) patient was in Stage IIA& four (80%) in Stage IIB - IIIB. The serous type histology was predominant (60%), 60 % were of grade 2 and 40% of high grade. All showed complete response (CR) to adjuvant paclitaxel and carboplatin (P+C).The mean progression-free survival (PFS) rate was 43.6 months and mean Overall survival (OS) was 51 months. Conclusion: PFTC is infrequently diagnosed preoperatively or intraoperatively due to its rarity, and has nonspecific presentation. Radical cytoreductive surgery, followed by postoperative adjuvant chemotherapy P+C is a standard treatment by which the survival potential of PFTC can be greatly enhanced.
