Using univariable analysis, the following variables showed potential prognostic value (p ≤ 0.10) for long‐term response: lower WHO PS, metastatic disease, PD‐L1 CPS ≥1, higher SMI, higher VATI, higher SATI, and absence of significant weight loss during the first 6 weeks of treatment (Table 2). This evidence concerns the gene CD274 and metastatic neoplasm.
