Management of cancer symptoms: pain, depression, and fatigue.

For cancer-related pain, an updated search was performed in MEDLINE, Cancerlit and the Cochrane Controlled Trials Register from December 1998 to June 2001 for English language studies (see Other Publications of Related Interest no.1). Additional studies were sought by checking the bibliographies of meta-analyses and selected review articles, and by consulting technical experts. Studies were excluded if they were in the previous report.
