The pelvis is the basin-shaped cavity that contains the bladder, rectum, and reproductive organs. The internal reproductive organs include the ovaries, fallopian tubes, uterus, and cervix for women, and the prostate and various ducts and glands for...

men. Pelvic exenteration is performed to surgically remove cancer that involves these organs and that has not responded well to other types of treatment. Pelvic exenteration is also indicated when cancer returns after an earlier treatment. In women, the operation is performed mostly for advanced and invasive cases of endometrial, ovarian, vaginal, and cervical cancer; for aggressive prostate cancer in men; and rectal cancer in either sex.

Orbital exenteration is performed to remove the eye and surrounding tissues when cancer of the orbital contents cannot be controlled by simple removal or irradiation. It is often the only course of treatment for advanced cancers of the eyelid, eyeball, optic nerve, or retina.

Exenteration is a major operation for both patient and surgeon; it is technically very challenging because it involves elaborate reconstructive surgery. Although it is a radical surgical procedure, exenteration often provides the only opportunity available for patients to eliminate the cancer and to prevent it from recurring.
