Mayo Clinic experience with epithelial ovarian cancer

Clinical investigation of epithelial ovarian cancer must involve the precise definition of the lesion, careful application of new techniques, the objective evaluation of such techniques, the comparison of results in a randomized fashion with prior forms of therapy, careful pathological evaluation of the tumour, and the evaluation of toxicity to the patient. The interdisciplinary team approach to the treatment of epithelial ovarian cancer and the development of randomized, prospective trials are essential. Utilizing these two elements, a better integration of surgery, chemotherapy and radiation therapy can be accomplished. Of great importance is the evaluation of response patterns by an observer who is skilled in pelvic examinations and familiar with the natural history of epithelial ovarian cancer. The increasingly important role of surgery in the treatment of this cancer is now more clearly defined. The psychological effects of chemotherapy as well as the response patterns to chemotherapy must be evaluated. During the past 20 years, considerable progress has been made in prolonging the useful, functional life of the patient. The ultimate cure is still a matter for the future and is predicated on more effective combinations of potent chemotherapeutic combinations and a clearer definition of the role of radiation therapy.
