Burden of illness and treatment patterns among patients with peripheral T-cell lymphoma in the US healthcare setting.

OBJECTIVE: Limited real-world information exists on the characteristics or treatment patterns of patients with peripheral T-cell lymphoma (PTCL). We reported demographics, treatments and direct healthcare resource utilization (HRU) in a large cohort of US patients newly diagnosed with PTCL. METHODS: Patients aged ≥18 years with a PTCL diagnosis between January 2011 and December 2016 were identified from the Inovalon MORE2 Registry. Continuous medical/pharmacy enrollment 6-months prior to and ≥1-month after the first PTCL diagnosis was required. The main focus of this study was on newly diagnosed patients receiving cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) versus other chemotherapy. RESULTS: A total 2971 patients with PTCL and chemotherapy information were included in the study; 1706 (57%) received CHOP and 1265 (43%) other chemotherapy. A majority of patients (51.7%) were female; mean (standard deviation) age at index was 61.0 (±16.0), Charlson score was 4.1 (±2.9), and follow-up time was 24.6 (±16.7) months. During the variable follow-up period, HRU was similar for the CHOP and other chemotherapy cohorts; 58.1% and 59.3% had ≥1 all-cause hospitalizations, respectively. The proportion of patients with ≥1 PTCL-related hospitalizations was higher in the CHOP than in the other chemotherapy cohort (40.3% vs. 9.7%, respectively) and mean length of stay was longer (4.6 vs. 3.7 days per patient per month, respectively). CONCLUSIONS: This retrospective analysis of patients with PTCL revealed high levels of comorbidity and HRU; novel interventions that improve patient outcomes and reduce the HRU burden of PTCL are needed.
