    Abstract: We describe trends in the use of chemotherapy and hormonal therapy by nodal and estrogen receptor (ER) status in women with early-stage breast cancer. Methods Cases were randomly sampled from the population-based Surveillance, Epidemiology and End Results (SEER) program and physician verified treatment was examined. A total of 9,481 women, aged 20 years and older, diagnosed with early-stage breast cancer in 1987 to 1991, 1995, and 2000 were included in the study. Results The use of chemotherapy plus tamoxifen increased between 1995 and 2000 for women with node-negative, ER-positive breast cancer ≥ 1 cm (8% to 21%). Nearly 23% of women with node-negative and ER-positive tumors ≥ 1 cm received no adjuvant therapy. The use of chemotherapy alone increased to nearly 60% in women with node-negative, ER-negative tumors ≥ 1 cm (48% to 59%). However, in 2000, 16% of women with node-positive and ER-negative tumors received no adjuvant therapy and an additional 6% received tamoxifen alone. The influence of age can clearly be seen. Chemotherapy is given much less often in women 70 years or older. Conclusion The results from SEER areas across the United States suggest that physicians quickly responded to publications and guidelines regarding breast cancer therapy. The lack of definitive findings from clinical trials on the use of adjuvant therapy in women 70 years and older may explain the lower use in this group of women.

    Quality-of-Life Outcomes After Primary Androgen Deprivation Therapy: Results From the Prostate Cancer Outcomes Study
    American Society of Clinical Oncology (ASCO) ; 2001

    Abstract: PURPOSE: To compare health-related quality-of-life outcomes after primary androgen deprivation (AD) therapy with orchiectomy versus luteinizing hormone-releasing hormone (LHRH) agonists for patients with prostate cancer. PATIENTS AND METHODS: Men (n = 431) newly diagnosed with all stages of prostate cancer from six geographic regions who participated in the Prostate Cancer Outcomes Study and who received primary AD therapy but no other treatments within 12 months of initial diagnosis were included in a study of health outcomes. Comparisons were statistically adjusted for patient sociodemographic and clinical characteristics, timing of therapy, and use of combined androgen blockade. RESULTS: More than half of the patients receiving primary AD therapy had been initially diagnosed with clinically localized prostate cancer. Among these patients, almost two thirds were at high risk of progression on the basis of prognostic factors. Sexual function outcomes were similar by treatment group both before and after implementation of AD therapy. LHRH patients reported more breast swelling than did orchiectomy patients (24.9% v 9.7%, P 〈 .01). LHRH patients reported more physical discomfort and worry because of cancer or its treatment than did orchiectomy patients. LHRH patients assessed their overall health as fair or poor more frequently than did orchiectomy patients (35.4% v 28.1%, P = .01) and also were less likely to consider themselves free of prostate cancer after treatment. CONCLUSION: Most endocrine-related health outcomes are similar after surgical versus medical primary hormonal therapy. Stage at diagnosis had little effect on outcomes. These results provide representative information comparing surgical and medical AD therapy that may be used by physicians and patients to inform treatment decisions.

    Insurance Status and the Use of Guideline Therapy in the Treatment of Selected Cancers

    Abstract: This study estimates the impact of type of insurance coverage on the receipt of guideline therapy in a population-based sample of cancer patients treated in the community. Patients and Methods Patients (n = 7,134) from the National Cancer Institute's Patterns of Care studies who were newly diagnosed with 11 different types of cancer were analyzed. The definition of guideline therapy was based on the National Comprehensive Cancer Network treatment recommendations. Insurance status was categorized as a mutually exclusive hierarchical variable (no insurance, any private insurance, any Medicaid, Medicare only, and all other). Multivariate analyses were used to examine the association between insurance and receipt of guideline therapy. Results Adjusting for clinical and nonclinical variables, insurance status was a modest, although statistically significant, determinant of receipt of guideline therapy, with 65% of the privately insured patients receiving recommended therapy compared with 60% of patients with Medicaid. Seventy percent of the uninsured patients received guideline therapy, which was nonsignificantly different compared with private insurance. When stratified by race, insurance was a statistically significant predictor of the receipt of guideline therapy only for non-Hispanic blacks. Conclusion Overall, levels of guideline treatment were lower than expected and particularly low for patients with Medicaid or Medicare only. The use of guideline therapy for ovarian and cervical cancer patients and for patients with rectal cancers was unrelated to type of insurance. Of particular concern is the significantly lower use of guideline therapy for non-Hispanic black patients with Medicaid. After adjusting for other factors, only half of these patients received guideline therapy.

    Trends in Surgery and Chemotherapy for Women Diagnosed With Ovarian Cancer in the United States
    American Society of Clinical Oncology (ASCO) ; 2003

    Abstract: Purpose: We examined patterns of care in a population-based sample of 601 ovarian cancer patients diagnosed in 1991, and a sample of 566 women was selected in 1996 to examine trends in care. Patients and Methods: Patient cases were sampled from within the Surveillance, Epidemiology, and End Results program. Medical records were reabstracted, and treatment data were verified with the treating physician. Results: Across these two time periods, the percentage of women with presumptive stage I, II, and IV disease who received lymph node dissection increased. However, a significant number still were not precisely staged. More than 65% of women with ovarian cancer were given cyclophosphamide in 1991 compared with about 14% in 1996. Paclitaxel increased from 1% to 62% during that time. After adjusting for age, race or ethnicity, registry, income, insurance status, Charlson score, residency training program, and marital status, women with early-stage disease were significantly more often given National Institutes of Health Consensus Development Conference guideline therapy in 1996 than in 1991. However, for women with stage III and IV disease, the use of guideline therapy did not significantly increase. Older women and minorities consistently received less guideline therapy, and the lack of private insurance was an impediment for both Hispanic and non-Hispanic black women. Conclusion: Despite guidelines presented by several organizations, significant numbers of women with ovarian cancer are not being provided with appropriate care. This is particularly true for older and minority women, especially those without private insurance. Educational strategies must be devised to increase the number of women receiving guideline therapy and decrease disparities across population groups.
