Role of neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte-ratio (PLR) in unresectable hepatocellular carcinoma (uHCC): Subgroup analysis of patients treated with camrelizumab (cam) + rivoceranib (rivo) in the CARES-310 trial.
Bibliographic record
Abstract
e16197 Background: CARES-310 (NCT03764293) evaluated the combination of the PD-1 inhibitor, cam, and the VEGFR-2 tyrosine kinase inhibitor, rivo, compared to sorafenib (sor) for the treatment of 543 patients (pts) with uHCC. Cam + rivo significantly improved mOS (22.1 months [mo] [95% CI 19.1-27.2] vs 15.2 mo [13.0-18.5] HR 0.62 [95% CI 0.49-0.80]; one-sided p < 0.0001) and mPFS (5.6 mo [95% CI 5.5-6.3] vs 3.7 mo [2.8-3.7]; HR 0.54 [95% CI 0.44-0.67]; one-sided p < 0.0001) compared to sor. The most common (≥20%) grade ≥3 treatment-related adverse events (TRAEs) for cam + rivo were hypertension (37.5%) and increased AST (16.5%) vs palmar-plantar erythrodysesthesia syndrome (15.2%) for sor. An elevated level of inflammation, including NLR and PLR, have been associated with poor survival outcomes in pts with HCC (Lin S, et al. Trans Cancer Res. 2021). Here, we present a subgroup analysis of the CARES-310 trial evaluating the impact of baseline (BL) NLR and PLR status on pt outcomes. Methods: The subgroup of pts treated with cam+rivo and BL NLR < 5 or ≥5 and PLR < 300 or ≥300 were evaluated for mOS, mPFS, overall response rate (ORR), disease control rate (DCR), and safety. Results: Of 272 pts treated with cam+rivo, 64.3% of pts had extrahepatic spread, median AFP was 84.1 ng/mL, 86.8% were Child-Pugh (CP) class A5, 13.2% were CP class A6, 73.5% were ALBI grade 1, 26.5% were ALBI grade 2. Additionally, 249 pts had NLR < 5, 10 pts had NLR ≥5, 252 pts had PLR < 300, and 7 pts had PLR ≥300. Pts with BL NLR < 5 and PLR < 300 demonstrated improved outcomes in mOS, mPFS, ORR, and DCR vs pts with BL NLR ≥5 and PLR ≥300 (Table). Rates of any grade TRAEs and grade ≥ 3 TRAEs were comparable between pts with BL NLR < 5 and ≥5 and PLR < 300 and ≥300 (Table). Conclusions: These results suggest that NLR and PLR may serve as a prognostic marker in patients with uHCC, but larger studies are needed to validate these findings.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
