This study investigated the association between platelet-to-lymphocyte ratio (PLR), a readily available marker from routine blood tests, and IR in cancer survivors, aiming to find a more straightforward predictor of IR that could potentially simplify screening and monitoring processes in this high-risk population.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Methods: &lt;/strong&gt;This cross-sectional study analyzed data from 1,418 cancer survivors from the NHANES 2005-2018 database.

Multivariable logistic regression models were used to examine the relationship between PLR quartiles and IR, with restricted cubic spline (RCS) analyses to evaluate non-linear relationships. Covariates included demographic (age, gender, race/ethnicity), socioeconomic (marital status, education, family poverty income ratio), lifestyle (smoking status, alcohol consumption, sleep duration, physical activity) and health status variables (body mass index (BMI), history of cardiovascular disease, hypertension status).

Similarly, there were no differences in pathological T stage (pT0-1: 87.5% vs. 70.8%, P = 0.29), pathological N stage (N0: 41.7% vs. 29.2%, P = 0.55) or pathological stage (41.6% vs. 33.3%, P = 0.75). No significant difference in adverse events profiles between the two arms was observed.</p><p><strong>Conclusions: </strong>Adding denosumab to neoadjuvant chemotherapy was not associated with lower RCB or improved pathological stage in premenopausal HR+/HER2-negative breast cancer patients with comparable rate of BCS. No new safety signals were observed with the addition of denosumab.</p>","PeriodicalId":46797,"journal":{"name":"World Journal of Oncology","volume":"16 5","pages":"502-508"},"PeriodicalIF":2.2,"publicationDate":"2025-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12479071/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145201533","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
