CD4 and renal cell carcinoma: A pooled analysis from all pairs that were tested with both TCLs/TCLs + IFNγ and FTDs (n = 71; 22 MM, 19 RCC, 21 OC and 9 SAR) showed that tests against FTDs yielded a lower reactivity for CD8+ (p = 0.018, Figure S1A) and a higher reactivity for CD4+ TILs (p = 0.039, Figure S1B) compared to testing against TCLs/TCLs + IFNγ.
