Similarly, CD27 on memory B cells also showed increased risks for lung cancer subtypes (for LUAD, ORIVW =1.047; 95% CI: 1.009–1.086; PIVW =0.014; for LUSC, ORIVW =1.053; 95% CI: 1.008–1.099; PIVW =0.020; for SCLC, ORIVW =1.093; 95% CI: 1.002–1.192; PIVW =0.045). This evidence concerns the gene CD27 and small cell lung carcinoma.
