[Palliative chemotherapy in metastatic and locally advanced gastrointestinal tumor].

Systemic chemotherapy ensures better quality of life than supportive treatment alone in incurable patients.

The future of tumor therapy consists in sooner treatment of early stages and improved adjuvant therapeutic methods.
