Clinical Impact of Sarcopenia and Inflammatory/Nutritional Markers in Patients with Unresectable Metastatic Urothelial Carcinoma Treated with Pembrolizumab.

ABSTRACT: Sarcopenia is a muscle loss syndrome known as a risk factor of various carcinomas. The impact of sarcopenia and sarcopenia-related inflammatory/nutritional markers in metastatic urothelial carcinoma (mUC) treated with pembrolizumab was unknown, so this retrospective study of 27 patients was performed. Psoas muscle mass index (PMI) was calculated by bilateral psoas major muscle area at the L3 with computed tomography. The cut-off PMI value for sarcopenia was defined as ≤6.36 cm2/m2 for men and ≤3.92 cm2/m2 for women. Neutrophil-to-lymphocyte ratio (NLR) ≥ 4.0 and sarcopenia correlated with significantly shorter progression-free survival (PFS) (hazard ratio (HR) 3.81, p = 0.020; and HR 2.99, p = 0.027, respectively). Multivariate analyses identified NLR ≥ 4.0 and sarcopenia as independent predictors for PFS (HR 2.89, p = 0.025; and HR 2.79, p = 0.030, respectively). Prognostic nutrition index < 45, NLR ≥ 4.0 and sarcopenia were correlated with significantly worse for overall survival (OS) (HR 3.44, p = 0.046; HR 4.26, p = 0.024; and HR 3.92, p = 0.012, respectively). Multivariate analyses identified sarcopenia as an independent predictor for OS (HR 4.00, p = 0.026). Furthermore, a decrease in PMI ≥ 5% in a month was an independent predictor of PFS and OS (HR 12.8, p = 0.008; and HR 6.21, p = 0.036, respectively). Evaluation of sarcopenia and inflammatory/nutritional markers may help in the management of mUC with pembrolizumab.

Project description:ImportanceMetastatic urothelial carcinoma (mUC) presents a therapeutic challenge with poor outcome. Enfortumab vedotin has emerged as a promising treatment, necessitating a comprehensive evaluation of its effectiveness and safety.ObjectiveTo synthesize the available evidence on enfortumab vedotin, both as monotherapy and in combination with pembrolizumab, as an mUC treatment for the purpose of guiding clinical decision-making and future research.Data sourcesCochrane Library, MEDLINE (via PubMed), Google Scholar, and Web of Science were searched from database inception to August 31, 2024. Major conference abstracts from 2019 to 2024 were also included. Search strategy used a combination of Medical Subject Heading terms and free-text keywords related to mUC and enfortumab vedotin.Study selectionRandomized clinical trials and prospective studies investigating enfortumab vedotin in adult patients with mUC were included. Eleven studies met the inclusion criteria.Data extraction and synthesisTwo independent reviewers extracted data and assessed study quality using the Cochrane Risk of Bias tool 2 and Risk of Bias in Non-Randomized Studies of Interventions tool. The meta-analysis used a random effects model, while a network meta-analysis was performed using a frequentist approach.Main outcomes and measuresPrimary outcomes were disease control rate (DCR), objective response rate (ORR), and 1-year survival rate.ResultsThe 11 included studies (3 randomized clinical trials [27.3%] and 8 nonrandomized prospective studies [72.7%]) involved 2128 patients. Of these patients, 563 (26.5%) received enfortumab vedotin plus pembrolizumab, 814 (38.3%) received enfortumab vedotin without pembrolizumab, and 751 (35.3%) received chemotherapy. Enfortumab vedotin plus pembrolizumab was associated with a pooled DCR of 86% (95% CI, 83%-89%), ORR of 68% (95% CI, 64%-71%), and a 1-year survival rate of 79% (95% CI, 75%-82%). Enfortumab vedotin monotherapy had a pooled DCR of 73% (95% CI, 70%-76%), ORR of 43% (95% CI, 40%-47%), and a 1-year survival rate of 52% (95% CI, 48%-56%). Network meta-analysis revealed that enfortumab vedotin plus pembrolizumab significantly outperformed chemotherapy in ORR (odds ratio [OR], 3.47; 95% CI, 1.49-8.09; P = .004) and 1-year survival (OR, 2.32; 95% CI, 1.75-3.06; P < .001).Conclusions and relevanceIn this systematic review and meta-analysis, enfortumab vedotin plus pembrolizumab showed high response rates in first-line settings, while enfortumab vedotin monotherapy was associated with clinical benefit in later lines of therapy. These findings underscore the importance of personalized treatment approaches, and future research is warranted to refine enfortumab vedotin-based therapies for mUC management.
