Initial experience with 25 personal cases operated on by a technique of radical oophorectomy is reported. There was one operative death and two fistulae, but no other significant morbidity. The majority of patients were treated with radical post-operative chemotherapy, with early encouraging results. It is suggested that this type of surgery in combination with chemotherapy merits a wider appraisal in the management of those patients with ovarian cancer which has extended locally or metastasised within the pelvis. It may have a place in the management of a few patients with early Stage 3 disease.
