Background: The accuracy of screening mammography among Asian women in the United States has received little attention. We determined whether the accuracy of screening mammography for Chinese and Filipino women differs from that of white women.
Methods: We examined a cohort of white, Chinese, and Filipino women 40 years and older who underwent 200,402, 72,604, and 19,087 screening examinations, respectively, between January 1986 and December 2001 in San Francisco County, California, of whom 2177 were diagnosed with breast cancer within 12 months of a screening examination.
Background: Clinical and histopathologic characteristics that may predict risks of recurrence in women with ductal carcinoma in situ (DCIS) have not been consistently identified. We identified factors associated with recurrence as DCIS versus invasive breast cancer and determined the 5-year absolute risks of recurrence as a function of these factors.
Methods: We conducted a population-based cohort study among 1036 women in the San Francisco Bay Area who were aged 40 years or older when diagnosed with DCIS and treated by lumpectomy alone from January 1983 through December 1994.
Objective: To determine the efficacy of a spit tobacco (ST) intervention designed to promote ST cessation and discourage ST initiation among male high school baseball athletes.
Methods: This study was a cluster-randomized controlled trial. Forty-four randomly selected high schools in rural California were randomized within strata (prevalence of ST use and number and size of baseball teams) to either the intervention or the control group.
Background: With the large number of women having mammography-an estimated 28.4 million U.S.
