Carcinoma of the fallopian tube. Management and sites of failure.

Thirty patients with adenocarcinoma of the fallopian tube, treated between 1950 and 1981, were studied. Median age was 55 years, and mean parity was 1.3. Bleeding or discharge occurred as a presenting complaint in 47% of patients, abdominal distention or mass in 50%, and pain in 30%. Lesions were staged using a system analogous to the International Federation of Gynecology and Obstetrics (FIGO) classification for ovarian carcinoma. Nine patients had Stage I disease; 11, Stage II; 7, Stage III; and 3, Stage IV. Histologic differentiation was Grade 1 in 39% of the patients, Grade 2 in 18%, and Grade 3 in 43%. Primary surgical treatment consisted of total abdominal hysterectomy and bilateral salpingectomy in 70% of the patients; 23% had more extensive surgery, whereas 13% had less extensive surgery. Three patients with Stage I tumors were treated with surgery alone, and the remainder received postoperative radiation, chemotherapy, or both. Survival was unrelated to grade, but highly dependent upon stage. Survival at 5 years was 56% for Stage I, 27% for Stage II, 14% for Stage III, and 0% for Stage IV. Four of five patients treated after surgery with a combination of cisplatin, doxorubicin, and cyclophosphamide (PAC) survived at least 3 years. Patterns of initial treatment failure showed 56% with a component of pelvic failure, 50% with a component of upper abdominal failure, and 44% with extraperitoneal metastases as a component of failure. These results suggest the need for aggressive postoperative adjuvant therapy targeted at upper abdominal and distant sites for metastasis in all lesions beyond Stage I.
