Brief Summary

The survey is a retrospective study to evaluate the prognotic value of EGFR expression, KRAS mutations and tumor sideness in patients with metastatic colorectal cancer treated with regorafenib and FOLFIRI as a third- or fourth-line setting.

Detailed Description

Primary objective:

Progression-free survival

Secondary objecive:

Overall survival, best objective response, disease control rate and adverse events

Number of Subjects: 41 patients with metastatic colorectal cancer treated with regorafenib and FOLFIRI as a third- or fourth-line setting.

Plan of the Study:

1. This is a retrospective study.

2. Study Schedule Study date: the time getting approval letter issued by both regulatory authority and institutional review board (IRB). Duration of the study: 5 years.

3. Duration of Treatment: Treatment was administered until disease progressed.

Regorafenib plus FOLFIRIUGT1A1 genotyping (TA6/TA6)Regimen for treatment consists of irinotecan (180 mg/m2 as a 120-min IV infusion for UGT1A1 genotyping (TA6/TA6) and UGT1A1 genotyping (TA6/TA7); 120 mg/m2 as a 120-min IV infusion for UGT1A1 genotyping (TA7/TA7)), followedby Leucovorin (400 mg/m2 IV infusion over 2 hours), and 5-FU (2800 mg/m2 IV infusion over a 46-hour period), repeated every 2 weeks. After every 2 cycles of each different dose of irinotecan, if adverse events (AEs) are under the grade 2, we will escalate the dose of 30 mg/m2. The estimated maximal dose of irinotecan is 260 mg/m2 for UGT1A1 genotyping (TA6/TA6); 240 mg/m2 for UGT1A1 genotyping (TA6/TA7); 180 mg/m2 for UGT1A1 genotyping (TA7/TA7). Regorafenib is administered at adjusted doseage of 120 mg daily for 3 weeks in a 4-week cycle.
