PTGS2 and non-small cell lung carcinoma: It is worth noting that some gene panels were specific or associated in all the four NSCLC-associated samples (Neu_c3_CST7, RSAD2_Neu, S100A2/Pabpc1_Neu, ISG15/Ifit3_Neu, CD74_Neu, PTGS2/Actg1_Neu, SPP1_Neu), meaning that changes in the distribution of these cell populations would have a high degree of confidence in assessing disease changes.
