To further decipher the effect of PCDHGB7 in real-world setting in patients with lung cancer undergoing immunotherapy, the BEST database was employed, and the data from the IMvigor210 cohort and Kim cohort showed that PCDHGB7 expression functioned as an effective predictor for immunotherapy response (Figure 4H AUC curves). The gene discussed is PCDHGB7; the disease is lung cancer.
