Further study identified the coexpression of AFAP1-AS1 and PD-1 in infiltrating lymphocytes in NPC samples, and patients with positive expression of both AFAP1-AS1 and PD-1 had the poorest prognosis [104], suggesting that coexpression of AFAP1-AS1 and PD-1 may be an ideal target for future clinical trials of anti-PD-1 immune therapy. The gene discussed is AFAP1; the disease is nasopharyngeal carcinoma.
