[Clinical study of primary carcinoma of the fallopian tube: experience with 14 cases].

Between 1950 and 1986, 14 cases of primary carcinoma of the fallopian tube were treated and diagnosed at the Cancer Institute Hospital. These cases constituted 0.13% of the total number of gynecologic malignancies at the hospital during the period. The clinical/pathological findings and prognoses were described. Of the 14 cases, the average age was 56.0 years. The most frequent symptom was atypical genital bleeding, seen in 11 cases (79%). Massive watery discharge was seen in four cases (29%). In preoperative cytologic examination of vaginal smears, six cases (43%) were positive for cancer. All cases underwent operation as therapy. Postoperative irradiation, adjuvant chemotherapy, and/or second-or third- look operation was also used. Histopathologically, all materials were found to be adenocarcinoma. Four cases were well differentiated, seven were moderately differentiated, and three were poorly differentiated. Two patients with stage III and IV cancers died of the disease. Nine patients were still alive at the end of this study. The five-year survival rate was 57% (4/7). In stage I cancers, the five-year survival rate was 80% (4/5). The prognosis of stage I cancer patients was estimated as rather good.
