To describe therapy and changes in therapy over time for women diagnosed with ductal carcinoma in situ (DCIS) and treated in the community setting. Women aged 20 or older diagnosed with DCIS in this study were sampled from the population-based Surveillance, Epidemiology and End Results Program. A total of 770, 1055, 480, and 404 women with DCIS were selected in 1991, 1995, 2000, or 2005, respectively.

Patients And Methods: Results from the National Cancer Institute's Patterns of Care study from 10 regional cancer registries in 1998 and 14 registries in 2002 were compared using univariate and multivariate statistical methods.
Results: Patients with localized prostate cancer in 2002 were younger, had lower prostate-specific antigen values, and higher Gleason scores compared with those diagnosed in 1998.

The clinical importance of human epidermal growth factor receptor-2 (HER2) in breast cancer is now clearly established, given that expression of this tumor marker is used to guide therapy and as a prognostic indicator. Despite its now routine evaluation in breast cancer patients, population-based data are lacking because information on HER2 status is not routinely collected in the majority of population-based cancer registries. We assessed the feasibility of collecting HER2 data and its completeness in three registries in the Surveillance Epidemiology and End Results (SEER) Program.

Purpose: Latinas and African-Americans with breast cancer, especially those of lower socioeconomic status and acculturation, have been underrepresented in studies assessing treatment satisfaction, decision-making, and quality of life. A study was designed to recruit a large and representative sample of these subgroups.
Materials And Methods: Incident cases were selected by rapid case ascertainment (RCA) in the Los Angeles Surveillance, Epidemiology, and End Results Registry from 2005 to 2006, with oversampling of Latinas and African-Americans.
