Randomized Controlled Trial Comparative Study Clinical TrialA randomized comparison of misonidazole sensitized radiotherapy plus BCNU and radiotherapy plus BCNU for treatment of malignant glioma after surgery: final report of an RTOG study.
This randomized RTOG study evaluated misonidazole radiosensitized radiation therapy in the treatment of malignant glioma. One hundred and forty-six evaluable patients were treated with conventional radiation therapy to 60.00 Gy in 6-7 weeks plus BCNU 80 mg/m2/d for 3 days every 8 weeks (XRT + BCNU). One hundred and forty-seven evaluable patients were treated with misonidazole 2.5 gm/m2 once a week for 6 weeks, radiation therapy to 60 Gy and BCNU (MISO + XRT + BCNU). ⋯ The median survival for XRT + BCNU was 55.0 weeks, and for MISO + XRT + BCNU 46.0 weeks (p = 0.35). With patients on a minimum dose of dexamethasone of 3 mg/d, misonidazole neurotoxicity included 8.8% peripheral neuropathy, 2.7% CNS toxicity, and a 0.68% ototoxicity. BCNU pulmonary toxicity occurred in 9.3% of patients who received 902-2062 mg/m2 of BCNU.

Carcinoma of the intact uterine cervix, stage IB-IIA-B, greater than or equal to 6 cm in diameter: irradiation alone vs preoperative irradiation and surgery.
This is an analysis of 123 patients with Stage IB-IIA-B carcinoma of the intact uterine cervix, 6 cm or greater in diameter, who were treated with curative intent at the University of Florida with radiation alone or radiation followed by a hysterectomy between October 1964 and February 1982. There is a minimum follow-up of 2 years in all patients; 87% of all recurrences and 91% of pelvic recurrences occurred within this time period. Examination of pelvic control rates, as well as disease-free survival, showed no significant advantage in pelvic control, disease-free survival, or absolute survival for either treatment group when compared by stage and tumor size. The incidence of severe complications was 6% for patients treated with irradiation alone and 15% for those treated with irradiation and surgery (p = 0.119).

Radiation therapy alone or combined with surgery in the treatment of barrel-shaped carcinoma of the uterine cervix (stages IB, IIA, IIB).
This retrospective analysis reports the results of therapy in 128 patients with carcinoma of the uterine cervix classified as barrel-shaped or expanded cervix (over 5 cm in diameter). Seventy-five percent of the patients were treated with irradiation alone and 25% with combinations of irradiation and surgery. The results of therapy are compared with those observed in 714 patients with non-barrel-shaped carcinoma of the uterine cervix treated with similar techniques during the same period of time. ⋯ In the barrel-shape group, eight patients treated with irradiation alone or survival of 70%, compared to 45% in 24 patients treated with irradiation alone. However, these differences are not statistically significant (p = .50). In eight patients treated with definitive irradiation and a lymphadenectomy and four patients irradiated after an exploratory laparotomy, two major and three minor (grade 2) complications were noted.(ABSTRACT TRUNCATED AT 400 WORDS)
