Inflammation-based biomarkers and artificial intelligence show promise for risk stratification and prediction of survival and second primary cancers (SPCs). We conducted a retrospective multicentre study including 405 NPC patients from six European institutions. Demographic, clinicopathological, and haematolo… gain_title: Machine learning classifiers using demographic, clinicopathological and inflammatory markers predicted 5-year overall survival and second primary cancer occurrence in a European nasopharyngeal carcinoma cohort. problem_title: (none) trace_subject: (none) gain_reading: Machine learning classifiers using demographic, clinicopathological and inflammatory markers predicted 5-year overall survival and second primary cancer occurrence in a European nasopharyngeal carcinoma cohort. gain_evidence: Systemic inflammatory markers modestly improved overall survival prediction and substantially enhanced second primary cancer risk estimation problem_reading: (none) problem_evidence: (none) quick_read: In a retrospective analysis of 405 patients from six European centers, investigators built machine learning models to predict 5-year overall survival and second primary cancer risk in nasopharyngeal carcinoma, a rare cancer in Europe. The cohort had a median age of 52, was 91.6% White/European ancestry, and showed 66.6% 5-year survival with 12.8% developing second primaries. The work matters because it provides the first ML prognostic models derived from a predominantly Caucasian European cohort and suggests low-cost inflammatory markers add predictive value, especially for second cancers. Uncertainty remains about generalizability beyond six centers, clinical utility given modest AUCs of 0.66 for survival and 0.74 for second cancers, and prospective validation. limitation: Retrospective design in a rare European disease with modest discriminative performance and limited cohort size of 405 patients. tag: Evidence-backed gain key_points: Retrospective multicentre study of 405 NPC patients from six European institutions, median age 52 years, 91.6% White/European ancestry, 77.3% received chemoradiotherapy. | Five-year overall survival was 66.6% and 12.8% developed second primary cancers. | Random Forest was best for OS prediction with accuracy 0.74 and AUC 0.66 using complete feature set; SPC prediction reached accuracy 0.80 and AUC 0.74. | Exclusion of inflammatory markers led to consistent decline in accuracy, with feature-importance analysis highlighting inflammatory ratios among strongest predictors. rundown: Researchers assembled 405 nasopharyngeal carcinoma patients from six European institutions, predominantly White/European ancestry, to address poorer outcomes reported in Caucasian versus Asian populations and lack of region-specific tools. They trained and tested multiple machine learning classifiers with and without systemic inflammatory ratios to predict 5-year overall survival and second primary cancer occurrence, reporting best results with Random Forest and noting improved accuracy when inflammatory markers were included. sources: - peer_reviewed | European Archives of Oto-Rhino-Laryngology | https://doi.org/10.1007/s00405-026-10461-z | 2026-07-17 prev: 0000000000000000000000000000000000000000000000000000000000000000

How to verify without trusting this page
Fetch the canonical text of any version from /api/record/TRV-2026-0246 and hash it yourself — for example shasum -a 256 on the saved canonical field. The result must equal content_hash, and each version’s text ends with prev:followed by the prior version’s hash (version 1 chains to 64 zeros). If a single character of any version had been altered since certification, the chain would not reproduce.
