Malignant gastrointestinal tumors are still worldwide a very common cause of death from cancer. Even though the surgical techniques and the neoadjuvant/adjuvant therapies have improved over the last years and multimodal concepts in cancer treatment have been established, these types of tumors remain a challenge. Therefore predictive/prognostic markers need to be established, to be able to tailor chemotherapies and therefore improve efficacy of neoadjuvant/adjuvant treatment. Over the last years potential predictive/prognostic factors have been characterized by molecular-biological technologies: the tumor suppressor gene p53, the cell-cycle regulatory proteins p21 and p27, the marker of proliferation Ki-67, the epidermal growth factor receptor, HER2/neu, angiogenetic factors (the vascular endothelial growth factor, cyclooxygenase 2, thymidine phosphorylase), enzymes involved in the DNA-repair-system (ERCC1), enzymes involved in the 5-fluorouracil-metabolism (thymidylate synthase, dihydropyrimidine dehydrogenase) or other genetic alterations, like the loss of heterozygosity or the microsatellite instability. The results of the mainly retrospective studies are promising but prospective studies are needed to validate those markers in the therapy of gastrointestinal tumors. The goal is that we will be able to predict when and with what to treat.
