Blood biomarkers to predict the efficacy of neoadjuvant chemo-immunotherapy in non-small cell lung cancer patients.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: Neoadjuvant chemo-immunotherapy has increased the number of patients with advanced lung cancer eligible for surgery. However, only a small number of such patients respond to this approach. Intensive research is being conducted to identify biomarkers to predict the efficacy of neoadjuvant chemo-immunotherapy. Among these, blood predictive biomarkers are particularly promising, and have the advantages of being both non-invasive and cost effective. This study aims to evaluate the predictive value of blood biomarkers in determining the efficacy of neoadjuvant chemo-immunotherapy for patients with non-small cell lung cancer (NSCLC), addressing a critical need for more personalized treatment strategies in clinical practice. Methods: We retrospectively collected the data of 199 NSCLC patients who received neoadjuvant chemo-immunotherapy from January 1, 2021 to December 31, 2023, at Zhejiang Cancer Hospital. We then analyzed the performance of blood biomarkers in predicting the efficacy of neoadjuvant chemo-immunotherapy. Results: The patients in the major pathological response (MPR) group had significantly higher pre-treatment squamous cell carcinoma antigen (SCCA) levels, and a significantly lower post-treatment platelet-lymphocyte ratio (PLR) than those in the non-MPR group. For patients with higher pre-treatment SCCA levels, the 1- and 2-year event-free survival (EFS) rates were 97.87% [95% confidence interval (CI): 94.99-100.00%] and 93.21% (95% CI: 84.32-100.00%), respectively. In those with lower pre-treatment SCCA levels, the 1- and 2-year EFS rates were 91.39% (95% CI: 84.93-98.35%) and 82.24% (95% CI: 72.42-93.39%), respectively. The survival analysis showed that higher pre-treatment SCCA levels were correlated with improved EFS (P=0.02) in patients receiving neoadjuvant chemo-immunotherapy. Conversely, for patients undergoing surgery alone, high pre-treatment SCCA levels were correlated with a poorer prognosis [disease-free survival (DFS), P=0.001]. These findings confirm the value of SCCA levels in predicting which patients will have a more favorable response to neoadjuvant chemo-immunotherapy. In patients receiving neoadjuvant chemo-immunotherapy, a high post-treatment PLR indicated a poorer prognosis (P=0.02). The Cox regression analysis indicated that the pre-treatment SCCA level (P=0.04) and post-treatment PLR (P=0.04) were independent predictive factors of EFS. Conclusions: In patients receiving neoadjuvant chemo-immunotherapy, high pre-treatment SCCA levels and low post-treatment PLRs were significantly associated with better efficacy and survival. Thus, these biomarkers could be used to guide the choice of treatment modalities.
