The Impact of Primary Tumor Site on Survival in Mycosis Fungoides.

Mycosis fungoides (MF) is the most common cutaneous T-cell lymphoma (CTCL), but little is known about the influence of anatomic location of the primary disease site on overall survival (OS) and disease-specific survival (DSS). The purpose of this study was to examine the significance of primary tumor site on survival in MF. A search of the Surveillance, Epidemiology, and End Results (SEER) database was conducted for patients with a diagnosis of MF with a specified primary site from 2000 to 2019. Prognostic factors including demographic and tumor characteristics were examined using Cox regression models. Further research is needed to fully investigate primary disease site as a prognostic indicator, including a deeper dive into MF of all stages and subtypes.
