Supportive care for patients with gastrointestinal cancer.

Supportive care has traditionally been given to optimise the comfort of patients and their ability to function, as well as to minimise the side-effects of anti-cancer treatments. The scope of modern comprehensive supportive care however is broadening and covers not only specific palliative treatment but non-tumour specific treatment such as social, psychological and spiritual support. In oncology, best supportive care (BSC) has been used as a comparator arm of randomised controlled trials in chemotherapy. However the BSC arm is usually not well defined and its evaluation is therefore difficult because of the heterogeneity of the definitions. A systematic review was undertaken of the evidence from all RCTs of gastrointestinal cancers (includes gastrointestinal/gastric, colorectal/colon cancer but excludes pancreatic cancer trials) which include a BSC/SC arm.
