Treatment of advanced bladder cancer with combined preoperative irradiation and radical cystectomy versus radical cystectomy alone: a phase III intergroup study.

PURPOSE: Our study was designed to compare the effects of preoperative irradiation and cystectomy to surgery alone in patients with transitional cell carcinoma of the bladder. MATERIALS AND METHODS: A total of 140 patients with documented invasive bladder cancer or rapidly recurring superficial high grade tumors was randomized to receive 2,000 rad of pelvic irradiation followed by cystectomy within 1 week or surgery alone. RESULTS: The 5-year survival rate was 53% (95 confidence intervals 41 to 65%) in the surgery only group and 43% (95% confidence intervals 30 to 56%) in the irradiation plus surgery group. The p value for the log rank statistic comparing the survival distributions was 0.23. CONCLUSIONS: Although this trial showed no benefit for preoperative irradiation and cystectomy, the confidence intervals were wide. This finding does not exclude the possibility of a favorable effect of radiation in a subset of patients with high stage tumors. Overall, however, the dominant effect of distant disease as a cause of treatment failure diminishes any potential impact of radiation on results.

Breast and cervical carcinoma screening services: physicians' perceptions of need.

The Mississippi Breast and Cervical Cancer Control Coalition conducted a survey of health care professionals to assess current practices in the areas of breast and cervical cancer screening. A 22% response rate was obtained, with family practitioners having the highest response rate. Cost was cited as a major barrier to access to screening mammography. Some discrepancies between provider perceptions and currently accepted guidelines were identified.

Personality characteristics of men who physically abuse women.

OBJECTIVE: Studies have suggested that personality disorders may be common among men who habitually commit domestic violence. The study reported here attempted to characterize personality traits and psychological and cognitive characteristics of men who batter women in order to distinguish them from nonbattering men. METHODS: A group of 21 batterers were compared with a group of nonbatterers using the Minnesota Multiphasic Personality Inventory and its personality disorder scales (MMPIPDS) and the Hostility and Direction of Hostility Questionnaire. Comparability of the two groups was assessed on several demographic variables and on scores on the Revised Michigan Alcoholism Screening Test, three cognitive measures, and three measures of affective disturbance. RESULTS: Batterers scored higher on only the borderline and antisocial MMPIPDS and on the acting-out hostility and self-criticism scales of the hostility questionnaire. Problem-solving skills for both of the groups were considerably poorer than published norms. No significant differences were found between the groups in age, race, education, socioeconomic status, alcohol abuse, performance on cognitive measures, depression scale scores, or overall scores on the MMPI. As children, batterers were more likely to have experienced physical or emotional abuse. CONCLUSIONS: Men who commit domestic violence may be found among a larger pool of men with poor problem-solving skills, but in addition they appear to have borderline-antisocial personality traits, certain types of hostility, and histories of abuse as children that may predispose them to become violent with their female companions.

Treatment of stages B3 and C seminoma with chemotherapy followed by irradiation therapy. Southwest Oncology Group Study.

Beginning in 1981, 28 patients with advanced seminoma were treated with combination chemotherapy followed by irradiation to evaluate the possibility of improved survival using both modalities. The treatment protocol consisted of two courses of vincristine, actinomycin-D, and cyclophosphamide followed by reassessment. Those initially presenting with Stage B3 disease who achieved a complete response to two cycles of chemotherapy then underwent irradiation. All others were given a third course of chemotherapy before undergoing irradiation. The pre-radiation portion of this protocol produced a complete response rate of only 25 percent, substantially less than other, more recent, protocols. Radiation therapy produced a complete response in 69 percent of those who did not achieve a complete response from chemotherapy, increasing the complete response rate from 25 percent to 64 percent. Given this response rate to radiation therapy and the difficulty of dissection and associated morbidity with the surgical excision of postchemotherapy residual masses, the best option at this time may be observation with salvage chemotherapy and/or radiation reserved for those with disease progression.

Plasma oestradiol, luteinizing hormone and progesterone during the oestrous cycle in the Beagle bitch.

PIP: Plasma levels of estradiol 17-beta, progesterone, and luteinizing hormone were measured during proestrus, estrus, and metestrus in 3 beagle bitches. Progesterone concentrations rose during estrus and remained increased for most of metestrus. Maximum concentrations of luteinizing hormone were observed on the first or second day of estrus, when ovulation is believed to occur. Estradiol 17-beta levels, much lower than those found for a woman during the menstrual cycle, increased proestrus, with maximum levels attained 1 day before the luteinizing hormone peak, and fell rapidly at time of the peak. Findings suggest that luteinizing hormone release in the dog is stimulated by an increase in estradiol secretion during proestrus.^ieng
