Lee et al.22 studied 76 patients diagnosed with DLBCL of the intestine; they reported a three-year progression-free survival rates (PFS) of 92.2% in the surgery followed by the R-CHOP group compared with 74.8% in the R-CHOP alone group (p = 0.009), while OS was 94.2% and 80.7% (p = 0.049), respectively. This evidence concerns the gene DDIT3 and diffuse large B-cell lymphoma.
