Association between GRIm score and response to nivolumab monotherapy in patients with advanced malignant melanoma.
Article in Journal of cancer research and clinical oncology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis that pooled it.
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/
objectivesMalignant melanoma is an aggressive skin cancer with significant metastatic potential. Immune checkpoint inhibitors (ICIs), particularly those targeting the PD-1 pathway, have revolutionized treatment, improving survival rates. A PD-1 inhibitor, Nivolumab, has demonstrated durable responses in advanced melanoma patients. However, response variability necessitates predictive biomarkers for patient stratification.
methodsThe Gustave Roussy Immune Score (GRIm Score) is a prognostic tool integrating lactate dehydrogenase (LDH), neutrophil-to-lymphocyte ratio (NLR), and albumin levels to predict ICI efficacy. This retrospective study evaluated the association between the GRIm Score and response to nivolumab monotherapy in 40 patients with stage IV malignant melanoma treated between 2020 and 2024. Patients were classified into low-risk (score 0-1) and high-risk (score 2-3) groups.
resultsResults showed that patients with a low GRIm Score had significantly longer median progression-free survival (21.4 vs. 6.3 months, p = 0.003) and overall survival (26.5 vs. 7.2 months, p < 0.001). Multivariate analysis confirmed the GRIm Score as an independent prognostic factor (HR: 1.593, 95% CI: 1.156-2.197, p = 0.004), surpassing the predictive power of its components.
conclusionsThis study is the first to validate the GRIm Score in malignant melanoma, suggesting it is a valuable biomarker for patient selection in immunotherapy trials. The findings highlight its potential in refining treatment decisions, though further validation in larger, multicenter cohorts is required.
