Background: Extensive print, radio, and television coverage about the dangers of sun exposure and benefits of sun protection occurred over the past decade. Illinois teen knowledge and attitudes about sun exposure/protection, sun-exposure/protection behavior, and information sources were determined by a summer telephone survey., Methods: Telephone interviews with 658 teenagers between ages 11 and 19 included African-American, Asian, Hispanic, Native American, and white teenagers., Results: Teens knew that too much sun was harmful as it caused skin cancer and sunburn. Sunburn was mentioned more often by those with skin types that burned easily and tanned poorly (I,II) (P < 0.001), was better known to girls than to boys (P < 0.001), and was recognized more by those with higher socioeconomic status (P < 0.001) but was not associated with age. Widely held sun exposure attitudes were socializing with friends and feeling better when outdoors. On weekdays, boys averaged 5.3 hr (SD, 1.65 hr) outside compared with 3.9 hr (SD, 0.75 hr) for girls (P < 0.001). Teenage boys were more likely to obtain occupational sun exposure, and girls sunbathed. Subjects with skin types I and II reported an average of 3.3 sunburns in the past year. During unprotected sun exposure, extensive numbers of teens with moderate-risk skin type experienced at least 1 sunburn per year. Indoor tanning use was more prevalent among older girls and those with skin types I and II. Sunscreen use was associated with water recreational activities (swimming, water sports, and going to the beach) by girls slightly more than by boys (P < 0.001). Hat-wearing was more common among boys than among girls., Conclusions: Teen knowledge that excessive sun exposure causes skin cancer and sunburns and that wearing sunscreens and hats were sun-protective methods did not enable sun protection that prevented burning. This is particularly troublesome because severe sunburns in youth are associated with an increased risk of melanoma. Existing teen sunscreen use could be broadened by educating teens to use adequate quantities of sunscreen prior to daily sun exposure to prevent painful burns. Messages to teens that emphasize the short-term consequence of painful sunburns because of inadequate protection during outdoor occupational and non-water-related recreational exposure would increase the relevance of the message and may enable behavioral change. Parents and physicians need to be included in messages that are directed to teens and to become part of their education. Parents could ensure an adequate sunscreen supply for daily use by the family, encourage teens not to deliberately tan, and serve as role models for the use of protective clothing.

Objective: To evaluate the relationship between survival and patterns of clinical management for ovarian carcinoma., Design: Retrospective analysis of cancer registry data including follow-up, operative reports, and pathology reports., Setting: Seventy-seven Illinois hospitals with active cancer registries., Patients: A total of 2669 women with newly diagnosed ovarian carcinoma from 1983 through 1988., Main Outcome Measures: Frequency of use of specific staging procedures and treatment options. Survival was estimated using the Kaplan-Meier product-limit method., Results: Thirty percent of 632 stage I patients, 31% of 233 stage II patients, and 45% of 516 stage III patients underwent hysterectomy, bilateral salpingo-oophorectomy, omentectomy, sampled peritoneal washings, and node biopsy. Five-year survival for those receiving this extensive surgery (who were therefore pathologically staged) was as follows: stage I, 80%; stage II, 63%; and stage III, 28%. For those not receiving this extensive surgery (who were therefore clinically staged), the 5-year survival at these stages was 76%, 62%, and 21%, respectively. The overall survival curves were not significantly different between those who were pathologically staged and those who were clinically staged for stage I patients (P = .27) or stage II patients (P = .47), but were for stage III patients (P = .01). Platinum-based combination chemotherapy was given to 76% of 221 patients with pathological stage III disease. Their 5-year survival--50% for the group with no residual disease and 20% for the group with residual disease--was better than for those receiving regimens without platinum--37% and 5%, respectively, for the two groups--and the overall survival curves were significantly better for those receiving platinum (P < .0005 for both groups). The groups receiving platinum had younger patients., Conclusions: Extensive surgery for pathological staging was not usually done for management of ovarian cancer, while platinum-based chemotherapy was commonly used. Failure to undergo extensive surgery had little impact on survival for stage I and II patients. However, use of extensive surgery and platinum-based chemotherapy improved survival for stage III patients. The improved survival for this group receiving platinum-based chemotherapy may be explained in part by selection of younger patients for this treatment.

A follow-up study was conducted by the Illinois Division of the American Cancer Society (ACS) in conjunction with the ongoing National Cancer Prevention Study II (CPSII) to determine whether self-report dietary changes are occurring in accordance with the ACS nutrition guidelines and to identify demographic subgroups that may be targeted for future prevention and education programs. A total of 42,300 CPSII respondents completed a 1986 questionnaire and were matched to 1982 baseline data. Dietary items were recorded as "on the average, how many days per week do you eat the following foods?" Individuals with known chronic conditions, body mass index outside a moderate range, and fewer than four completed food items were excluded. The remaining study population (n = 18,062) included men and women who were apparently healthy and primarily over the age of 50. The distribution of foods reported in 1982 and changes in foods consumed (1982-1986) among selected food groups varied modestly by sex, age, and educational level. Modest changes in the direction of decreasing intake of high-fat foods and increasing intake of high-fiber foods and cruciferous vegetables were reported. Dietary changes consistent with the ACS nutrition guidelines appear to have taken place in this population, particularly for the use of fried foods in males and intake of high-fiber foods and cruciferous vegetables in females.

Renal pelvic transitional cell carcinoma constitutes about 7 percent of all kidney cancer. This report is a summary of 611 Illinois patients with this tumor treated between 1975 and 1985. Overall, the five-year relative survival rate was 62 percent and the observed five-year rate was 48 percent. Stage was a major determinant of survival, as expected, in these cancer patients. The Illinois experience is reviewed and compared with the accumulated literature experience with renal pelvic cancers since 1944.

Objective: To determine the degree of compliance with clinical standards among hospitals for care of breast cancer patients and account for variations in compliance., Design: Analysis of cancer registry data submitted to the American Cancer Society, Illinois Division, Chicago, for a concurrent prospective descriptive study of breast cancer, supplemented by other hospital data from public sources., Setting: Ninety-nine Illinois hospitals evenly distributed among rural counties, counties with small cities outside the Chicago metropolitan area, exurban counties in the Chicago metropolitan area, suburban Cook County, and urban Chicago., Patients: A total of 5766 newly diagnosed patients with histologically confirmed breast cancer in 1988, representing 84% of the estimated 6900 new cases in the state for that year., Main Outcome Measures: Descriptive statistics and multiple linear regression analyses of five dependent quality variables from clinical indicators related to early diagnosis, hormone receptor determination, adjuvant therapy, radiation therapy, and axillary lymph node dissection., Results: At the hospitals studied, (1) late stage (IIb through IV) at diagnosis was associated with urban location, higher proportion of poorly insured patients, fewer breast cancer cases treated, and lower oncology charges (proportion of variance explained, R2 = .50, P less than .00001); (2) omission of hormone receptor test for stages II through IV was associated with urban location and higher proportion of poorly insured patients (R2 = .18, P less than .00003); and (3) omission of indicated radiation therapy was associated with urban location and fewer breast cancer cases (R2 = .21, P less than .00001). Omission of adjuvant therapy and omission of axillary lymph node dissection were not significantly associated with any of the hospital variables examined., Conclusions: The findings suggest that there is a group of urban hospitals, generally small and marginally reimbursed, where comprehensive diagnosis and treatment of breast cancer are not obtained.

A personal 222Rn and gamma-ray detector has been developed. The detector precision is limited only by the Poisson counting error and has a lower limit of detection in this study of 4.5 kBq m-3 h (4 pCi L-1 day). The detector was used in a study of 52 homes in Illinois to measure the personal exposure vs. the simultaneous exposure on all levels of the home. The ratio of personal exposure to basement 222Rn concentration averaged 0.22, with a high degree of scatter (R2 = 31%). The ratio of personal exposure to first floor 222Rn concentration was 0.71, with good correlation (R2 = 85%). In the absence of personal monitoring data, the best estimate of personal exposure appears to be from measurements in the first-floor living space of the home.

A retrospective study of survival results for pancreatic cancer was performed. The study had two objectives: 1) to relate the extent of disease and management to survival, and 2) to determine whether newer treatment combinations have altered prognosis. Cancer registrars from 88 Illinois hospitals reviewed original medical records and submitted standardized report forms on 2,401 patients diagnosed between 1978-84. Three-year survival time was longer after laparotomy/bypass plus radiation/chemotherapy than for laparotomy/bypass alone (P less than .02). But the difference in survival between resection versus resection, radiation, and chemotherapy was not significant (P = .16). After resection, the median survival for 78 Stage I patients was 12.5 months, whereas for 181 Stage I patients after laparotomy/bypass it was 6.8 months (P less than .00001). For patients without metastases, 3-year survival was significantly better for 249 patients in whom cancer was resected versus 568 unresected patients (P less than .001). Survival was longer for 568 unresected patients without gross metastases than for 954 patients with metastatic disease found at laparotomy (P less than .05). From this study the authors concluded that: 1) since 3-year survival results were higher than expected after resection for localized cancers, resection is still desirable when it can be done with acceptable complication risks, and 2) the use of multiple treatment modalities for pancreatic cancer warrants further study in organized trials.

A retrospective analysis of survival results for colorectal cancer patients in Illinois was performed by the Cancer Incidence and End Results Committee of the Illinois Division of the American Cancer Society. Cancer registry data on 1,774 patients from 63 hospitals were used to investigate whether the preoperative level of serum carcinoembryonic antigen (CEA) was a prognostic indicator of survival for cancers diagnosed between 1976 and 1978. A direct relationship was found between the preoperative level of serum CEA and both the thickness and stage of the tumor at initial diagnosis. For Stage B2/3 colorectal cancer, the actuarial survival curves corresponding to normal, elevated, and markedly elevated CEA levels were significantly different (p less than 0.0001). The five-year survival rates for these patients were 61, 50, and 32 percent, respectively. Similar trends for patients with Stage C2/3 cancer were observed (p = 0.0058). The corresponding five-year survival rates were 44, 30, and 26 percent, respectively. Using a statewide cancer registry system, the analysis suggested that the preoperative level of serum CEA was an indicator of survival in patients with colorectal cancer, independent of the stage of disease at diagnosis.
