A prospective trail comparing hysterectomy, hysterectomy plus vaginal radium, and uterine radium plus hysterectomy in stage I endometrial carcinoma.

From 1958 to 1967, a prospective randomized trial was conducted in 189 women with stage I, group I endometrial adenocarcinoma, comparing treatment by hysterectomy alone, preoperative uterine radium followed by hysterectomy, and hysterectomy and postoperative vaginal radium. All women have been followed for a minimum of 10 years. The actual survival rate at 5 years for all patients was 94.5% and at 10 years, 92.6%, with no statistical significance among the 3 treatment groups. Ther was also no statistical significance in survival rate in relation to size of uterine or myometrial invasion. There was a statistically significant difference in survival between grade I and grade III lesions (P less than 0.01) and between grade II and grade III lesions (P less than 0.05).

Melphalan chemotherapy in advanced ovarian carcinoma.

One hundred and eleven consecutive women with FIGO Stages III and IV ovarian adenocarcinoma were treated with melphalan as their initial chemotherapy. The response rate was 19.8% with 10.8% having a complete response. There was a statistically significant improvement in response in those women with no prior radiation therapy. Moreover, there was a statistically significant improvement in median survival in those patients achieving a complete response to melphalan as compared to those with a partial response, with no change or progression of their malignancy. A review of the results of maximal surgery and combination chemotherapy is presented as a plan of therapy to improve upon the results of melphalan chemotherapy in women with advanced ovarian carcinoma.

Microinvasive carcinoma of the vulva.

A case is presented of a patient with microinvasive carcinoma of the vulva which was treated by conservative surgery. Six years later, the patient developed inguinal and pelvic lymph node recurrence of carcinoma. A review of the literature on similar cases is also presented.

Effect of triamcinolone acetonide aerosol upon exercise-induced asthma.

The effect of triamcinolone acetonide aerosol upon exercise-induced asthma was compared with that of placebo in a double-blind, crossover study in 11 asthmatic children. Measurement of pulmonary function before and after treatment and before and after exercise disclosed inhibition of exercise-induced asthma in only three of nine children in whom exercise after inhalation of placebo caused bronchospasm.

Phase III randomized pilot study comparing interferon alpha-2b in combination with radiation therapy versus radiation therapy alone in patients with stage III-B carcinoma of the cervix.

This randomized pilot study was designed to determine whether the addition of interferon alpha-2b to standard radiation therapy offered an advantage in loco-regional control and survival over radiation therapy alone in a homogeneous group of patients with stage IIIB carcinoma of the cervix. Thirty-six patients were treated with a combination of interferon alpha-2b plus radiation therapy, and 38 patients were treated with radiation therapy alone. Patients with evidence of ureteral obstruction were excluded from the study. Evaluation of loco-regional response was determined by pelvic examination, cervical cytology, biopsies and CT scans when indicated. Survival time was measured from initiation of treatment to date of death or last follow-up. Patient characteristics were comparable between both study arms. The objective complete response rate was 67% in the combined therapy group and 55% in the radiation alone group (P = 0.454). With a median follow-up of 17 months for all patients and 31 months for live patients, 50% of the combined group survived vs. 39.5% of the radiation alone group (P = 0.424). We conclude that the addition of interferon alpha-2b to standard radiation therapy did not significantly improve loco-regional response or survival, although such a trend was noted. We encourage the design of a larger randomized study with sufficient power to detect meaningful differences to prove whether the tendency observed in the present investigation holds any promise to improve the outcome of these patients.

Recurrent ovarian dysgerminoma after laparoscopy.

To our knowledge, recurrent dysgerminoma at the site of tumor removal by laparoscopy in a patient with stage IA disease has not been previously reported. A woman with ovarian dysgerminoma treated by laparoscopy and tumor removed through the cul-de-sac recurred the 17 months later at the site of tumor removal. She was successfully treated with etoposide, bleomycin, and cisplatin chemotherapy with complete response. This case illustrates the potential for surgical site implant of an ovarian dysgerminoma; surgeons should follow strict guidelines when performing laparoscopic procedures for ovarian malignancies in order to prevent this type of incident.

Effect of epidermal growth factor on ornithine decarboxylase activity in A431 cells.

Epidermal growth factor (EGF) stimulates mitogenesis in a number of cell lines; but in A431 cells, EGF causes inhibition of replication. To investigate the possibility that an alteration in the polyamine biosynthetic pathway could be associated with this unusual response of A431 cells to EGF, we evaluated the effect of EGF on ornithine decarboxylase activity. We also evaluated the action of inhibitors of ornithine decarboxylase (difluoromethyl ornithine and retinoic acid) on A431 cell replication. We found a significant stimulatory effect of EGF on ornithine decarboxylase activity and a significant inhibition of cell replication by ornithine decarboxylase inhibitors. These findings are suggestive that the paradoxical response of A431 cells to EGF stimulation is not due to an aberrant response in polyamine formation. Specifically, we found that A431 cells respond, like other cell types, to a growth factor (viz., EGF) with an increase in ODC activity. Moreover, in A431 cells ornithine decarboxylase activity is required for replication.
