The study evaluated the association between age and disease specific mortality among adults diagnosed with medullary thyroid cancer. Older adults and super-elderly were found to have a higher risk of increased mortality, with age being an independent predictor of disease specific mortality. The extent of surgery and lymphadenectomy did not affect disease specific mortality in these patients.
Background: The aim of this study was to evaluate the association between age and disease specific mortality (DSM) among adults diagnosed with medullary thyroid cancer (MTC). Method: Surveillance, Epidemiology, and End Results (SEER-18) was used to analyze adult MTC patients stratified by age (18-64, 65-79, >= 80 years). Associations between patient demographics, tumor size, nodal status, metastatic disease, and extent of surgery on DSM was assessed with multivariable Cox regression. Results: Among 1457 patients with MTC, 1008 (69.2%) were younger adults, 371 (25.5%) older adults, and 78 (5.4%) were super-elderly. A significantly higher proportion of older adults and super-elderly had less than the recommended operation for MTC. On multivariable analysis, older adults and super-elderly were 2.9 and 6.7 times more likely to have an increased DSM (HR:2.91, 95% CI: 1.83-4.63; p < 0.001 and HR: 6.70, 95%CI: 3.69-12.20; p < 0.001). Extent of surgery or lymphadenectomy did not affect DSM. Conclusions: Increased age is an independent predictor of DSM in patients with MTC. (C) 2020 Elsevier Inc. All rights reserved.
