Introduction
Lenvatinib (LEN) remains an important treatment option for unresectable hepatocellular carcinoma (uHCC) patients in the present immunotherapy era. Based on the recognized impact of nutritional status and systemic inflammatory response on cancer treatment outcomes, this study evaluated uHCC patients treated with LEN to determine the prognostic significance of a newly developed combination of geriatric nutritional risk index (GNRI) and the systemic inflammatory response marker C-reactive protein (CRP), known as GNRI-C score.
Aims & Methods
This multicenter retrospective study included 484 patients with uHCC who received LEN between 2018 and 2022. Initially, GNRI score was calculated to assess nutritional status based on serum albumin level, height, and body weight, with the cohort categorized into three groups; score 0 (GNRI >98), score 1 (GNRI 92–98), and score 2 (GNRI <92). Next, GNRI-C score, which integrates GNRI-based risk stratification with CRP level, with an additional 1 point assigned for CRP ≥1 mg/dL, used to classify the patients into four groups (score 0, 1, 2, or 3). In this manner, GNRI-C score was considered to provide a comprehensive assessment by incorporating both nutritional status and inflammation caused by the presence of a hepatocellular carcinoma. Treatment outcomes, including objective response rate (ORR), disease control rate (DCR) determined using RECIST v.1.1, progression-free survival (PFS), overall survival (OS), and impact of GNRI-C score on prognosis, were subsequently analyzed.
Results
The median follow-up period was 12.9 months. Patient median age was 73 years and 79.3% were male. A GNRI-C score of 0 was noted in 220, 1 in 109, 2 in 106, and 3 in 49 patients. For GNRI-C scores of 0, 1, 2, and 3, treatment response analysis showed ORR values of 51.3%, 45.7%, 50.0%, and 38.9%, respectively, and DCR values of 84.8%, 83.0%, 85.1%, and 83.3%, respectively, with no significant differences (p = 0.517, p = 0.963, respectively). Similarly, adverse event incidence rates did not significantly differ among the patient groups formed by GNRI-C score. On the other hand, for patients grouped based on GNRI-C score of 0, 1, 2, and 3, median PFS was significantly different at 10.79, 7.46, 5.75, and 3.68 months, respectively (p <0.001), as was median OS at 28.61, 19.64, 10.25, and 8.21 months, respectively (p <0.001). Even for patients who received lenvatinib as first-line therapy, significant differences for PFS (9.86, 7.46, 6.43, and 4.25 months, respectively) and OS (34.57, 20.14, 10.75, and 8.21 months, respectively) were noted when divided using GNRI-C score (p <0.001). Finally, comparative prognostic analysis demonstrated the superiority of GNRI-C over other scoring systems, as the Akaike Information Criterion score for OS prediction was lowest for GNRI-C (2887.19), outperforming GNRI, mALBI grade, NLR, O-PNI, and neo-GPS.
Conclusion
GNRI-C score, which integrates nutritional and inflammatory markers, is considered to be a superior prognostic tool for assessing uHCC patients undergoing LEN treatment. This simple and objective scoring system may aid clinicians in identifying high-risk patients and also optimizing treatment strategies.
