A case of stage IV carcinoma of the ovary is presented which was treated approximately six years ago in the Department of Radiation Therapy at Queens Hospital Center. On September 12, 1972, the patient had a total abdominal hysterectomy and bilateral salpingo-oophorectomy for a papillary scirrhous cystadenocarcinoma of the left ovary. At the time of the operation, the patient was found to have stage IV carcinoma of the ovary due to metastases of the liver and rectum. She was scheduled to receive pelvic-abdominal postoperative radiation therapy via the moving strip technique. Unfortunately, after completion of two strips, the patient could not tolerate treatment. She then began chemotherapy with a single agent, chlorambucil.Chlorambucil, 0.2 mg/kg/day×25 days/course was administered. The patient received 18 courses. Treatment dosage on a few occasions was decreased and increased again, due to drops in hemoglobin level and white blood cell and platelet counts. At the time of this presentation, the patient has no signs or symptoms of the disease. The introduction of megavoltage radiotherapy and adjuvant chemotherapy postoperatively has significantly improved the prognosis for patients with ovarian carcinoma. However, despite progress in radiotherapy, some patients cannot sustain this kind of treatment due to the unwanted side effects. Such was the case in this patient. She was switched to chemotherapy with excellent results in response and survival, even cure.
