Regorafenib is a valuable treatment option for metastatic colorectal cancer patients who have progressed after prior standard treatments. Prior progression-free survival data suggest that there could be a distinct subgroup of patients that may benefit from regorafenib. The aim of this study is to identify predictive biomarker of regorafenib in terms of its efficacy.
Regorafenib is a multi-tyrosine kinase inhibitor which has been shown to increase survival in metastatic colorectal cancer patients who have progressed after prior standard treatments. Progression-free survival data suggest that there could be a distinct subgroup of patients that may benefit from regorafenib. Therefore, it would be important to identify predictive biomarker of efficacy of regorafenib. Considering that regorafenib is a multi-tyrosine kinase inhibitor, comprehensive approach is required to discover predictive biomarker.
NGS-based sequencing allows generating large amount of data regarding multiple genes and multiple genetic alterations within a single experiment. Also, it requires less amount of DNA or tissue and cost compared to currently used individual gene testing techniques such as direct sequencing or FISH. Moreover, superior sensitivity over Sanger sequencing can be obtained by increasing coverage depth, especially in cases with low tumor purity. Wide range of genes targeted by regorafenib and genes in the major oncogenic pathway of colorectal cancer influenced by regorafenib can be efficiently assessed using NGS-based sequencing.
The aim of this study is to identify predictive biomarker of efficacy of regorafeinib in metastatic, refractory colorectal cancer patients using NGS technology.

Tumors or cancer of the COLON or the RECTUM or both. Risk factors for colorectal cancer include chronic ULCERATIVE COLITIS; FAMILIAL POLYPOSIS COLI; exposure to ASBESTOS; and irradiation of the CERVIX UTERI.
Tumor suppressor genes located in the 5q21 region on the long arm of human chromosome 5. The mutation of these genes is associated with the formation of colorectal cancer (MCC stands for mutated in colorectal cancer).
Tumor suppressor genes located in the 18q21-qter region of human chromosome 18. The absence of these genes is associated with the formation of colorectal cancer (DCC stands for deleted in colorectal cancer). The products of these genes show significant homology to neural cell adhesion molecules and other related cell surface glycoproteins.
A group of autosomal-dominant inherited diseases in which COLON CANCER arises in discrete adenomas. Unlike FAMILIAL POLYPOSIS COLI with hundreds of polyps, hereditary nonpolyposis colorectal neoplasms occur much later, in the fourth and fifth decades. HNPCC has been associated with germline mutations in mismatch repair (MMR) genes. It has been subdivided into Lynch syndrome I or site-specific colonic cancer, and LYNCH SYNDROME II which includes extracolonic cancer.
Nuclear phosphoprotein encoded by the p53 gene (GENES, P53) whose normal function is to control CELL PROLIFERATION and APOPTOSIS. A mutant or absent p53 protein has been found in LEUKEMIA; OSTEOSARCOMA; LUNG CANCER; and COLORECTAL CANCER.
