Cancer disparities: developing a multidisciplinary research agenda - preface.

In this Special Issue, we present a series of papers concerned with developing a multidisciplinary research agenda to address social disparities in cancer. Motivating this Special Issue are two concerns: (1) despite major advances in knowledge during the 20th century about the extent, determinants, treatment, and prevention of cancer, social disparities in cancer, including within the United States, remain serious, persistent, and require redress; and (2) huge gaps in knowledge exist regarding the causes of and solutions to social disparities in cancer across the full cancer continuum, from prevention to occurrence to diagnosis to treatment and, all too often, to death. Consequently, critical research is critically needed, both to answer the unanswered questions and to ascertain why existing knowledge is not implemented to reduce and eliminate these disparities. To help advance work in this field, we share papers developed for a January 2004 workshop on cancer disparities held at the Dana Farber/Harvard Cancer Center (DF/HCC), in Boston, MA. Topics addressed include: the definition and magnitude of, and programmatic responses to, social disparities in cancer, plus development of a systematic approach to raising research questions to address cancer disparities, using the case examples of breast, cervix, colon, and prostate cancer.
