## ABSTRACT

Gastrointestinal track cancer is the malignant condition of the gastrointestinal tract and is a major health problem worldwide. The prognosis for patients with gastrointestinal tract cancer is grim. Most of the gastrointestinal cancer cases are reported as metastatic cancer. Surgery is an option for gastrointestinal cancer, but results vary depending on the affected organ. For example, it is a curative option in 50% of colorectal cancers, whereas it is less effective in gastric cancers where the overall 5-year survival rate is less than 10% (Hasegawa et al. 2003).
