[Correlation Research between Syndrome Elements of Chinese Medicine and KRAS, BRAF, NRAS Gene Mutations in Advanced Colorectal Cancer Patients].

Objective To study the correlation between syndrome elements of Chinese medicine (CM) and KRAS, BRAF, NRAS gene mutations in advanced colorectal cancer patients. Methods Syn- drome elements of CM, KRAS, BRAF, NRAS gene mutations (mutation " +" & wild type/non-mutation " --") were collected in 33 advanced colorectal cancer patients. The correlation between gene mutations and syndrome elements of CM was analyzed using binary Logistic regression. Results Wild type KRAS (KRAS-) was negatively correlated with Gan depression syndrome (P =0. 043, P <0. 05), while KRAS mutation (KRAS + ) was positively correlated with Gan depression syndrome (P =0. 043, P <0. 05). KRAS-and KRAS + had no significant relation with Pi deficiency, Fei deficiency, Shen deficiency, yang deficiency, yin deficiency, qi deficiency, blood deficiency, phlegm turbidity, qi stagnation, and blood sta- sis (P>0. 05). BRAF-and NRAS-had no significant relation with Gan stagnation, Pi deficiency, Fei defi- ciency, Shen deficiency, yang deficiency, yin deficiency, qi deficiency, blood deficiency, phlegm turbidi- ty, qi stagnation, and blood stasis (P >0. 05). Positive BRAF and NRAS were seldom found in this study, so they were not statistically analyzed. Conclusions There existed correlations between gene mutations and Gan stagnation. KRAS-was negatively correlated with Gan depression, while KRAS+ was positively correlated with Gan depression. Whether there exists mutation of BRAF or NRAS was not correlated with syndrome elements of CM.
