Colon cancer with metastase in the diagnose time account for one significant rate and has a increasing trend. The treatment result of this patient group rests modest. The biological therapeutic treatment is still expensive for major part of Vietnamese patients. So that, research on a new affordable and efficacious chemotherapy combination for these patients is extremely necessary in our country The purpose of the study is to comment somes clinico-pathology features of metastatic colon cancer patients whose disease was not radically resectable. The second aim is to Evaluate the treatment result and toxicity of FOLFOXIRI in these patients
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"

Patients' characteristic
Clinico-pathology features of metastatic colon cancer patients whose disease was not radically resectable
Time frame: 4 years
Response rate after 3 cycles
Responses are evaluated according to WHO criteria. The determination of responses and progression was initially based on investigator-reported measurements; computed tomography scans of all responding patients and of patients with stable disease were subsequently subjected to external review by an independent panel.
Time frame: At the end of Cycle 3 (each cycle is 4 weeks)
Response rate after 6 cycles
Responses are evaluated according to WHO criteria. The determination of responses and progression was initially based on investigator-reported measurements; computed tomography scans of all responding patients and of patients with stable disease were subsequently subjected to external review by an independent panel.
Time frame: At the end of Cycle 6 (each cycle is 4 weeks)
Correlation between response rate and percentage of chemotherapy dosage
Prognostic factor of response rate
Time frame: 4 years
Correlation between response rate and histopathology
Prognostic factor of response rate
Time frame: 4 year
Correlation between response rate and metastatic site
The average size of the hepatic metastatic lesion in the study
Time frame: 4 years
Prognostic factor for response rate after 3 cycles
Evaluation of predictor of response rate
Time frame: At the end of cycle 3 (each cycle is 4 weeks)
Prognostic factor for response rate after 6 cycles
Evaluation of predictor of response rate
Time frame: At the end of cycle 6 (each cycle is 4 weeks)
Mean of the progression free survival
The median progression free survival of the study population
Time frame: 4 years
Prognostic factor of progression free survival
Evaluation of predictor of progression free survival
Time frame: 4 years
Number of Participants with Adverse Events as a Measure of Safety and Tolerability
During the full length of first-line treatment, number of enrolled patients reporting adverse events is recorded. Adverse events are evaluated according to National Cancer Institute Common Toxicity Criteria latest version.
Time frame: 4 years
Overall survival after 12 months
The percentage of survival patients 12 month after finishing treatment with FOLFOXIRI regimen
Time frame: 12 months after the last patient finish chemotherapy
Overall survival after 24 months
The percentage of survival patients 24 month after finishing treatment with FOLFOXIRI regimen
Time frame: 24 months after the last patient finish chemotherapy
