BACKGROUND. Blacks are less likely than whites to develop bladder cancer; although once diagnosed, blacks experience poorer survival. This study sought to examine multiple biological and behavioral factors and their influence on extent of disease.METHODS. A population-based cohort of black bladder cancer patients and a random sample of frequency-matched white bladder cancer patients, stratified by age, gender, and race were identified through cancer registry systems in metropolitan Atlanta, New Orleans, and the San Francisco/Oakland area. Patients were ages 20-79 years at bladder cancer diagnosis from 1985-1987, and had no previous cancer history. Medical records were reviewed at initial diagnosis. Of the patients selected for study, a total of 77% of patients was interviewed. Grade, stage, and other variables (including age, socioeconomic status, symptom duration, and smoking history) were recorded. Extent of disease was modeled in 497 patients with urothelial carcinoma using logistic regression.RESULTS. Extent of disease at diagnosis was significantly greater in Blacks than in Whites. Older age group, higher tumor grade, larger tumors, and presence of carcinoma in situ were related to greater extent of disease in blacks and in whites. Large disparities between blacks and whites were found for socioeconomic status and source of care. Blacks had greater symptom duration and higher grade. Black women were more likely to have invasive disease than white women; this difference was not seen among men. Blacks in unskilled occupational categories, perhaps reflecting socioeconomic factors, were at much higher risk for muscle invasion than whites.CONCLUSIONS. While specific relationships between variables were noted, an overall pattern defining black and white differences in stage did not emerge. Future studies should examine the basis upon which occupation and life style factors operate by using biochemical and molecular methods to study the genetic factors involved.

To determine whether Black women with symptoms of uterine corpus cancer had longer times from symptom recognition to initial medical consultation than did White women in the United States, 331 newly diagnosed patients living in Atlanta (GA), New Orleans (LA), and San Francisco/Oakland (CA) during 1985-87 were interviewed to collect information on symptoms, dates of recognition and consultation, and other factors that might affect the interval. Data were analyzed to estimate medical consultation rates and rate ratios following symptom recognition. Median recalled times between symptom recognition and consultation were 16 days for Black women and 14 days for White women. Although poverty, having no usual source of healthcare, and other factors were associated with lower consultation rates, the adjusted rate among Black women was only somewhat lower (0.87) than among White women, and the 95 percent confidence interval (CI = 0.58-1.31) was consistent with no true difference between the races. In addition, the median time to consultation for women with stage IV cancer was only 15 days longer than the time (14 days) for the women with stage I cancer. These results suggest that time from symptom recognition to initial medical consultation does not contribute importantly to the more advanced stage cancer of the uterine corpus commonly found among Black women.

The relationship between social ties, stage of disease, and survival was analyzed in a population-based sample of 525 black and 486 white women with newly diagnosed breast cancer. There were significant differences between the two race groups in reported social ties. Using logistic regression to adjust for the effects of age, race, study area, education, and the presence of symptoms, there was little or no evidence for an association between individual network measures of social ties and stage of disease. However, a summary measure of social networks was found to be associated modestly with late stage disease, attributable in part to significantly more advanced disease among black, but not white, women reporting few friends and relatives [relative risk (RR) = 1.8; 95% confidence interval (CI) = 1.1-3.0]. With adjustments for differences in stage of disease and other covariates, and with the use of Cox proportional hazards modeling to estimate hazard ratios, the absence of close ties and perceived sources of emotional support were associated significantly with an increased breast cancer death rate. White women in the lowest quartile of reported close friends and relatives had twice the breast cancer death rate of white women in the highest quartile (RR = 2.1; 95% CI = 1.1-4.4). Notably, both black and white women reporting few sources of emotional support had a higher death rate from their disease during the 5-year period of follow-up (RR = 1.8; 95% CI = 1.3-2.5).(ABSTRACT TRUNCATED AT 250 WORDS)

Objective. —To examine the ability of recognized prognostic factors for breast cancer to account for the observed poorer survival in blacks compared with their white counterparts. Design and Participants. —Subjects included 1130 women (612 blacks and 518 whites) aged 20 to 79 years residing in metropolitan Atlanta, Ga, New Orleans, La, or San Francisco/Oakland, Calif, who were diagnosed with primary invasive breast cancer. Information on stage, tumor characteristics, treatment, comorbid conditions, and sociodemographic factors was obtained from personal interview, physician and hospital records, and a pathology review of biopsy and surgical specimens. Main Outcome Measure. —Multivariable survival models were used to estimate the hazard ratio (relative risk of mortality) for blacks compared with whites, adjusting for various combinations of potential explanatory factors. Results. —After controlling for geographic site and age, the risk of dying was 2.2 times (95% confidence interval [CI], 1.8 to 2.8) greater for blacks than whites. Adjustment for stage reduced the risk from 2.2 to 1.7; further adjustment for sociodemographic variables had no effect. Treatment was not a contributing factor once stage and tumor pathology were in the model. After adjusting for stage, treatment, comorbid illness, and pathologic and sociodemographic variables, blacks continued to demonstrate a slightly increased, but not statistically significant, risk of death (hazard ratio=1.3; 95% CI, 1.0 to 1.8). Results were similar for all-cause mortality and breast cancer—specific mortality. Conclusions. —Approximately 75% of the racial difference in survival was explained by the prognostic factors studied. Sociodemographic variables appeared to act largely through racial differences in stage at diagnosis, which may be amenable to change through improved access to and use of screening for black women.

Background: Numerous studies have reported differences in cancer staging at diagnosis and in survival between Black and White patients with breast cancer. Utilizing data obtained from the National Cancer Institute's (NCI's) Black/White Cancer Survival Study for the period 1985-1986, a new study is presented here that systematically examines multiple explanatory factors (e.g., lack of mammograms) associated with these cancer-staging differences. Purpose: We evaluated within a single study the relationship of selected demographic, lifestyle, antecedent medical experiences, and health care acces s factors to cancer staging at diagnosis in Black and White breast cancer patients. Methods: Data utilized in this population-based cohort study of 1222 eligible women (649 Black and 573 White) newly diagnosed for the period 1985-1986 with histologically confirmed primary breast cancer were obtained from the NCI's Black/White Cancer Survival Study. Sources of data included abstracts of hospital medical records, central review of histology slides by a study consultant pathologist, and patient interviews obtained from three metropolitan areas: Atlanta, New Orleans, and San Francisco-Oakland. Within each area, 70% of all Black incident cases were randomly selected, and a sample of White cases, frequency matched by age groups (20-49 years, 50-64 years, and 65-79 years), was selected for comparison. Stage of breast cancer at diagnosis was classified according to the international tumor-lymph node-metastases (TNM) system. Statistical models utilized in this study included the log-linear and polychotomous logistic regression with multiple predictor variables. Results: Factors associated with cancer staging were differentially expressed in Blacks and Whites. Indicators of access to health care, a lack of mammograms, and an increased body mass index significantly (P<.02) contributed to stage differences in Blacks, whereas income was marginally associated (P = .06) with stage for Whites only. Nuclear grade, having a breast examination by a physician, and a history of patient delay explained approximately 50% of the excess risk for stage III-IV Cancer versus stage I-II(N0) cancer among Blacks compared with Whites (odds ratio- reduction from 2.19 to 1.68). Conclusion: These findings suggest that no single factor or group of factors can explain more than half of the race-stage differences noted in this study with respect to Black and White breast cancer patients.

Background: Studies in the United States have reported that Black women have higher fatality rates than White women following a diagnosis of breast cancer and are more likely to be diagnosed with late-stage cancers. Purpose: To evaluate reasons for these racial differences, we explored the difference between Black and White women in the length of time from symptom recognition to initial medical consultation. We also evaluated the extent to which other factors related to the length of this interval might contribute to any observed racial difference. Methods: As part of a collaborative study of differences in the survival rates of Black patients and White patients with cancer, we interviewed a sample of 410 Black women and 325 White women from Atlanta, New Orleans, and San Francisco/Oakland who were newly diagnosed in 1985 or 1986 with invasive breast cancer. Retrospective data were collected on symptoms, dates of symptom recognition and initial medical consultation, and several other factors which may affect the interval between symptom recognition and medical consultation. Data were analyzed as if from a follow-up study, using product limit procedures and proportional hazards regression. Results: At diagnosis, Black women with breast cancer were two times more likely to have stage IV breast cancer and one and one-half times more likely to have stage III breast cancer than White women with breast cancer and were only approximately one-half as likely to have stage I breast cancer. Similarly, Black women were almost twice as likely as White women to have tumors that were larger than 5 cm or tumors that had extensions to the chest wall or skin at presentation. However, the average rate at which Black women with breast cancer obtained an initial medical consultation lagged behind that for White women by only a slight but statistically significant difference (15%). The median time between symptom recognition and medical consultation was slightly longer for Black women (16 days) than for White women (14 days) (P = .06). Adjustment for other characteristics predictive of the length of this interval had little effect on racial differences. The racial differences tended to vary somewhat by age and metropolitan area, suggesting that the results may not apply equally to all demographic subgroups and regions in the United States. Conclusion: This small difference in the time from symptom recognition to medical consultation is unlikely to account for the large racial differences in survival rates and in stage of disease at the time of diagnosis.

This article addresses whether delayed graduation due to academic difficulties in the early years of medical school can be predicted early and whether such difficulties are likely to be manifested in later clinical clerkships and residency. A group of 103 graduates who entered Jefferson Medical College between 1970 and 1984 and who required more than 4 years to complete their studies due to academic difficulties were compared to a random sample of 120 on‐time graduates. Statistically significant differences were observed between delayed and on‐time graduates on measures of performance before, during, and after medical school in favor of on‐time graduates. Scores of 8 on the Medical College Admission Test and an undergraduate science grade‐point average of 3.25 were found to be pivotal points below which the likelihood of delayed graduation was higher than the likelihood of on‐time graduation. Discriminant analyses indicated that 76% of delayed and on‐time graduates could correctly be classified into their...
