EBV status did not predict failure after nasopharyngeal cancer RT in Denmark
In 331 Danish NPC patients, five-year failure rates were similar by EBV status, while distant relapse was concentrated in locally advanced disease.

Treatment discontinuation was 25.0% with pre-RT cachexia versus 4.6% without, with approximately sixfold higher adjusted odds.
After propensity matching, overall survival was similar between surgery plus adjuvant RT and definitive RT, while disease-control differences remained non-significant.
Radical radiotherapy use nearly doubled while five-year lung cancer-specific survival rose from 21.9% to 33.1% across Northern Ireland.
