摘要

Background

Although there are multiple treatment options, oncologists lack appropriate biomarkers for determining the efficacy and toxicity of immunotherapy. In this study, we aimed to use a combination of the clinical parameters of IMDC risk groups at the time of diagnosis to predict the effectiveness of immunotherapy.

Methods

This multicenter cross-sectional study retrospectively analyzed non-small cell lung cancer (NSCLC) patients receiving nivolumab for the prognostic effects of clinical factors, including the IMDC score.

Results

Two hundred and five patients were enrolled in this study. There was no favorable group because the TTI was less than 1 year in the entire study group in the IMDC. The IMDC score and IMDC groups showed significant differences in PFS (p < 0.001; p < 0.001, respectively). Intermediate and poor-risk groups had PFS of 8 and 3 months PFS, respectively. The IMDC group showed a significant effect on OS (p = 0.002). The intermediate- and poor-risk groups had 12- and 4-month OS, respectively. The TTI risk factor excluded patient numbers in the favorable, intermediate, and poor risk groups were 47, 129, and 29, respectively, in the revised IMDC group (rIMDC). The prognostic effect of the rIMDC score and groups remained significant (p < 0.001 and p < 0.001, respectively). The classical IMDC had a significant effect on PFS in the multivariate analysis (p = 0.016). Also, rIMDC score in multivariate analysis resulted with significant effect on OS (p = 0.035).

Conclusion

To date, this is the first study to prove that the IMDC may be a valuable option for predicting both prognosis and treatment efficacy in NSCLC patients receiving especially second or further lines nivolumab treatment.
