Supplemental Material for "Recent Incidence Trends for Cutaneous T-Cell Lymphoma in the United States: A Surveillance, Epidemiology, and End Results (SEER) Database Analysis, 2000–2022"
Description
Supplemental tables accompanying a SEER-21 analysis of cutaneous T-cell lymphoma incidence in the United States, 2000–2022. Includes parallelism testing of incidence trends by demographic group (Table S1), 2022 age-adjusted incidence rates by CTCL subtype across demographic subgroups (Table S2), age-adjusted incidence rate ratios by subtype and subgroup (Table S3), and observed annual age-adjusted incidence rates with 95% confidence intervals by CTCL group (Table S4). Rates are per 1,000,000 person-years, age-adjusted to the 2000 US standard population. Trend analyses were performed in the Joinpoint Regression Program v5.4.0.0; rates and confidence intervals (Tiwari modification) were estimated in SEER*Stat.

Cases were identified in SEER*Stat from the SEER-21 registry (November 2024 submission) using ICD-O-3 morphology codes 9700/3, 9701/3, 9702/3, 9708/3, 9709/3, 9718/3, 9719/3, and 9726/3, restricted to primary cutaneous sites. Age-adjusted rates were computed against the 2000 US standard population and exported to the Joinpoint Regression Program v5.4.0.0 for trend and parallelism analysis.
