Irradiation of endometrial cancer in patients with medical contraindication to surgery or with unresectable lesions.

In 124 medically inoperable patients with endometrial cancer, the five and ten year actuarial survival rates were 68% and 57%. In 26 patients with technically unresectable endometrial cancer, 26% actuarial survival rates at both five and ten years were seen. Pelvic control at death was 89% in Stage Ia, 78% in Stage Ib, 82% in Stage II, and 62% in Stage III. Sophisticated intracavitary therapy alone or in conjunction with external irradiation appears to give better uterine control rates than does external irradiation alone.

Squamous cell carcinoma of the oral tongue and floor of mouth. Evaluation of interstitial radium therapy.

From January, 1965, to December, 1972, 46 patients with squamous cell carcinoma of the floor of the mouth and 102 patients with squamous cell carcinoma of the oral tongue were treated at M.D. Anderson Hospital and Tumor Institute by interstitial irradiation alone or in combination with external irradiation. Through the years the combination of radiation therapy modalities has been adjusted in an attempt to improve local control, keeping complications to a minimum. In this paper we analyze local control, causes of failure and complications as related to the primary size (T stage) and radiation therapy techniques employed.

Sealed sources in synthetic absorbable suture: a new method for permanent interstitial implantation.

Inactive gold grains are embedded at 1-cm intervals along a synthetic, absorbable surgical suture, then subjected to neutron irradiation in a nuclear reactor, forming a new material for permanent interstitial implant therapy. Assembling and activating the sealed sources in an absorbable carrier, the physical properties of the irradiated suture, its behavior in tissue, and the methods and results of implantation in the dog are described.

Postoperative treatment of early cancer of the ovary: a random trial between postoperative irradiation and chemotherapy.

One hundred and forty-nine patients with early cancer of the ovary who were suitable for postoperative radiotherapy were treated in a random study in which the efficacy of whole abdominal irradiation with additional irradiation to the pelvis was compared to that of chemotherapy with melphalan. The number of patients without evidence of disease at 2 years indicates that both treatments give similar results. However, the survivals among patients with stage I ovarian cancer showed an improvement for women treated with irradiation, survivals among patients with stage II ovarian cancer showed only a minor difference between women treated with irradiation and those treated with chemotherapy, and survivals among patients with stage III ovarian cancer improved for women treated with chemotherapy. The complications resulting from both treatments differed greatly. Melphalan was well tolerated; it caused serious bone marrow depression in only one patient. The blood counts of all patients after completing their prescribed chemotherapy promptly returned to normal levels. Seven patients treated with irradiation developed small bowel injury requiring surgery. Six of these patients, however, were treated with irradiation to the pelvis followed by strip irradiation to the entire abdomen. Since this treatment plan probably gives excessive doses of irradiation to the pelvis, it has been discontinued.

Results of chemotherapy as an adjunct to surgery in patients with localized ovarian cancer.

One hundred and forty-nine patients with early cancer of the ovary who were suitable for postoperative radiotherapy were treated in a random study in which whole abdominal irradiation with additional treatment to the pelvis was compared to chemotherapy with Melphalan. The number of patients without evidence of disease at 2 yr seems to show that the results of treatment are similar. When the Berkson-Gage method of projection is used, however, the survival rate in stage I is apparently improved with irradiation; there is only a minor difference in the results of the two methods in stage II, and survival rates are improved for patients with stage III disease who were treated with chemotherapy. The complications of treatment in this study were quite different. Melphalan was well tolerated, and only one patient had serious bone marrow depression as a result of this treatment. All had prompt recovery of blood counts to normal after completing the prescribed chemotherapy. Seven patients treated by radiotherapy developed a small bowel injury which required surgery. Six of these were treated with irradiation to the pelvis followed by strip irradiation to the entire abdomen. This treatment plan probably gives excessive doses of irradiation to the pelvis and has been discontinued. This type of complication is much less frequent with the other sequence of treatment--strip irradiation to the whole abdomen and subsequent treatment to the pelvis. The cost to the patient of the two treatment programs varied considerably. Patients who received irradiation had the added expense of living in Houston for the duration of treatment. Patients treated with chemotherapy were often seen a 2- or 3-mo intervals and had their chemotherapy supervised by their personal physician.
