Trends and Impact of Treatment Modalities (Surgery and Radiation Therapy) on Health Care Utilization in Patients With Glomus Jugulare Tumors (GJTs): An Inverse Probability of Treatment Weight Analysis.

Abstract

The trend of practice pattern and impact on health care utilization for surgery and radiation therapy (RT) in patients with glomus jugulare tumors (GJTs) is not well defined. The IBM (Armonk, NY) MarketScan database was queried using the ICD-9/10 and CPT 4th edition, 2000-2020. We included patients ≥18 years of age who underwent either surgery or RT with at-least 1-year follow-up. We compared the health care utilization at 3-month, 6-month, and 1-year follow up using the inverse probability of treatment weight technique. A cohort of 333 patients was identified. Of these, 72.7% (n = 242) underwent RT and 27.3% (n = 91) underwent surgery. RT use increased from 2002-2004 (50%) to 2017-2019 (91%). Patients in the surgery cohort were younger (median age 49 vs. 56 years, P < 0.0001) and had a higher 3+ comorbidity index (34% vs. 30%, P = 0.43) compared with patients in the RT cohort. Patients who underwent surgery had higher complications at index hospitalization (22% vs. 6%, P < 0.0001) and at 30 days (14% vs. 5%, P = 0.0042). No difference in combined index and 6- or 12-month payments were noted (6-months: surgery, $66m108, RT: $43m509, P = 0.1034; 12-months: surgery, $73,259, RT: $51,576, P = 0.1817). Only 4% of patients who had initial RT underwent RT and none underwent surgery at 12 months, whereas 6% of patients who had initial surgery underwent RT and 2% underwent surgery at 12 months. RT plays an increasingly important role in the treatment for patients with GJTs, with fewer complications and a comparable health care utilization at 1 year.
