Increased Mortality After Radiotherapy for Pituitary Adenoma
A study has found that patients with pituitary adenomas who received radiotherapy have a significantly higher mortality rate compared to the general population. The research indicates that cerebrovascular disease is a major contributor to these excess deaths. The findings suggest a need for further analysis of radiation techniques and their effects on patient outcomes.
- ▪Patients treated with radiotherapy for pituitary adenomas had a standardized mortality ratio of 1.8.
- ▪Cerebrovascular disease was identified as the leading cause of excess mortality in these patients.
- ▪Mortality rates increased with higher doses of radiotherapy, particularly for doses above 50 Gray.

TOPLINE:Pituitary adenomas, although benign, are associated with long-term health risks including excess cerebrovascular mortality. Patients who received radiotherapy with or without undergoing surgery had a notably higher rate of all-cause mortality than the general population, with cerebrovascular disease contributing most significantly to excess deaths.METHODOLOGY:Researchers evaluated the rate of long‑term mortality in a cohort of patients with pituitary adenomas treated with radiotherapy, compared observed mortality with expected national mortality, and assessed the major contributors to excess mortality.They retrospectively reviewed data of 426 patients with pituitary adenomas (42% women) who received radiotherapy between 1962 and 1994, with follow-up extending up to 50 years; 347…
