Chemotherapy In Neuroendocrine/Merkel Cell Carcinoma Of The Skin: Case Series And Review Of 204 Cases, Patricia Tai, Edward Yu, Eric Winquist, Alex Hammond, Larry Stitt, Jan Tonita, Jim Gilchrist

Edward Yu

Purpose: To study the use of chemotherapy for Merkel cell carcinoma (MCC) of the skin. Patients and methods: Twenty-five cases of MCC were treated at the London Regional Cancer Center between 1987 and 1997. Thirteen cases treated with chemotherapy were reviewed with 191 cases from the literature. Results: At presentation, 24 patients had localized skin lesions (stage I) and one had locoregional involvement (stage II). Among the nine cases with recurrent nodal disease, six had chemotherapy as a component of salvage treatment. They were all free of disease at a median of 19 months (range, 12 to 37 months). In …

Sulfa Or Sulfone Prophylaxis And Geographic Region Predict Mutations In The Pneumocystis Carinii Dihydropteroate Synthase Gene, Laurence Huang, Charles B. Beard, Jennifer Creasman, Deborah A. Levy, Jeffrey S. Duchin, Sherline Lee, Norman Pieniazek, Jane L. Carter, Carlos Del Rio, David Rimland, Thomas R. Navin

Journal Articles: Epidemiology

To determine factors associated with mutations in the Pneumocystis carinii dihydropteroate synthase (DHPS) gene, a prospective study of human immunodeficiency virus (HIV)-infected patients with confirmed P. carinii pneumonia was conducted in Atlanta, Seattle, and San Francisco. Clinical information was obtained from patient interview and chart abstraction. DHPS genotype was determined from DNA sequencing. Overall, 76 (68.5%) of 111 patients had a mutant DHPS genotype, including 22 (81.5%) of 27 patients from San Francisco. In multivariate analysis, sulfa or sulfone prophylaxis and study site were independent predictors of a mutant genotype. Fourteen (53.8%) of 26 patients who were newly diagnosed with …

An International Comparison Of Cancer Survival: Metropolitan Toronto, Ontario, And Honolulu, Hawaii, Kevin M. Gorey

Social Work Publications

OBJECTIVES: Comparisons of cancer survival in Canadian and US metropolitan areas have shown consistent Canadian advantages. This study tests a health insurance hypothesis by comparing cancer survival in Toronto, Ontario, and Honolulu, Hawaii.

METHODS: Ontario and Hawaii registries provided a total of 9190 and 2895 cancer cases (breast and prostate, 1986-1990, followed until 1996). Socioeconomic data for each person's residence at the time of diagnosis were taken from population censuses.

RESULTS: Socioeconomic status and cancer survival were directly associated in the US cohort, but not in the Canadian cohort. Compared with similar patients in Honolulu, residents of low-income areas in …
