? ? ? The importance of T cells in tumor immune evasion and as a target for drug therapy has been recognized, but relatively little research has been done on B cells
? ? ? The researchers conducted epidemiological analysis on a cohort of more than 1,000 colorectal cancer patients and found that patients with tumors homozygous for hIgG1-G396R genotype had significantly improved overall prognosis and progression-free survival, and multi-factor COX risk.
? ? ? The above studies indicate that the hIgG1-G396R variant may be an important protective prognostic factor for patients with colorectal cancer, revealing that hIgG1-G396R has the potential to be used as a prognostic indicator for patients in the field of colorectal cancer.
