Prognostic value of metabolic parameters of 18F-FDG PET/CT in advanced non-small cell lung cancer treated with first-line immunotherapy combined with chemotherapy / 中华放射医学与防护杂志
A total of 44 patients were enrolled. Univariate analysis showed that the factors influencing PFS were TMTV and the number of metastatic sites ( χ2=4.19, 11.28, P<0.05) and the factors influencing OS were TMTV and TLG ( χ2=14.96, 6.05, P<0.05). Multivariate analysis suggested that number of metastatic sites was an independent prognostic marker for PFS ( P=0.011) and TMTV was an independent prognostic marker for OS ( P=0.038).
