Fallopian Tube Cancer
Fallopian tube cancer is usually adenocarcinoma, manifesting as an adnexal mass or as vague symptoms. Diagnosis, staging, and treatment are surgical.
Primary fallopian tube cancer is rare. Average age at diagnosis is 50 to 60. Risk factors include chronic salpingitis, other inflammatory disorders (eg, TB), and infertility.
Most (> 95%) fallopian tube cancers are papillary serous adenocarcinomas; a few are sarcomas. Spread, like that of ovarian cancer, is by direct extension, by peritoneal seeding, or through the lymphatics.
Typically, CT is done. A distended solid adnexal mass and normal ovary suggest fallopian tube cancer. A pregnancy test is done to rule out ectopic pregnancy unless patients are postmenopausal.
If cancer is suspected, surgery is necessary for diagnosis, staging, and treatment. Staging (similar to that of ovarian cancer) requires the following:
Treatment includes total abdominal hysterectomy, bilateral salpingo-oophorectomy, and supracolic omentectomy. If cancer appears advanced, cytoreductive surgery is indicated.
Postoperative treatment is identical to that for ovarian cancer. External beam radiation is rarely indicated.
