In the world, colorectal cancer is the third most common cancer in male and the second most common cancer in female. In VietNam, the disease is the fourth cancer in male, the sixth cancer in female and increasing recently. About 20-40% of the colon cancer patients had distant metastasis at the time of diagnose, those treatment outcome remains poor (5years survival is about 11%). The targetted therapy medications are still not affordable for majority of Vietnamese patients. So that, 3 cytotoxic drugs (5-Fluoro-Uracil, Oxaliplatin and Irinotecan) remain back-bone in the treatment of metastatic colon cancer.
According to one meta-analysis, the overall survival rate significantly correlated to the use of all 3 these drugs in the treatment time. If patients were give two drugs as the doublet in a line (FOLFOX/XELOX, FOLFIRI/XELIRI), not 100% of patients are treated with all 3 these drugs because some abandonned the following treatment lines. So, the trials that give all 3 drugs in a line (first-line) as triplet (FOLFOXIRI) were carried out and had primirily good outcome. In 2010, FOLFOXIRI were recommended in NCCN guideline.
In VietNam, FOLFOXIRI has been applied to treat patient since 2013. However, since then there was no clinical trial to evaluate the efficacy and the toxicity of this combination. Therefore, we carried out the work "Research on the treatment of metastatic colon cancer patients treated by FOLFOXIRI"
