Keeping up with the cancer literature--PDQ ACCESS

Physician Data Query (PDQ) (National Cancer Institute [NCI], Bethesda, MD) and CANCERLIT (NCI, Bethesda, MD) are two online cancer information databases. PDQ summarizes current cancer therapy literature into specific treatment recommendations. CANCERLIT is a bibliographic system similar to MEDLINE (National Library of Medicine [NLM], Bethesda, MD) that provides a comprehensive source of literature citations for the field of cancer. In this report, we discuss linking PDQ and CANCERLIT with PDQ ACCESS (NCI, Bethesda, MD)--a custom software package that makes searching the cancer literature easy for the practicing physician unfamiliar with database searching.
