The expression, in both tumor and stromal compartments, of CD4 (p = 0.024 and p = 0.008, respectively), CD8 (p = 0.044 and p = 0.008, respectively), and LAG3 (p = 0.008, in both cases) were higher in adenocarcinoma (ADC) than in squamous cells carcinoma (SCC) patients. The gene discussed is CD8A; the disease is AIDS dementia complex.
