Major protocol deviations cut survival time for head and neck cancer patients

Patients with oligometastatic head and neck cancer received focused radiation therapy. The goal was to destroy cancer cells while sparing healthy tissue. Ninety-eight metastases were treated across sixty-nine patients. The team compared outcomes between those who followed the plan exactly and those with errors. Quality assurance reviews caught mistakes before they hurt patients. This review of the GORTEC 2014-04 trial looked at survival data after a median follow-up of fifty-five months. The median time lived was sixty-one months for those without errors. It dropped to fifty-one months with minor mistakes and twenty-one months with major ones. Major deviations mostly involved treating larger cancer clusters or areas near sensitive organs. These errors were linked to shorter survival times. The study found a strong connection between protocol errors and worse outcomes. This exploratory analysis of dosimetric indices suggests that strict quality checks matter. While this trial was small, the link between errors and survival is clear. Patients need consistent care to get the best chance at long-term survival.
