Palliative Therapy for Recalcitrant Cutaneous T-Cell Lymphoma of the Hands and Feet With Low-Dose, High Dose-Rate Brachytherapy

摘要

IMPORTANCE Cutaneous T-cell lymphoma (CTCL) of the hands and feet can be challenging to treat and cause significant disability for patients. Although CTCL is a highly radiosensitive tumor, the complex topography of acral surfaces presents challenges to achieving homogeneous superficial dosing of traditional electron beam therapy. In addition, traditional dosing may result in substantial acute cutaneous toxic effects. Recent reports demonstrate that low-dose palliative radiotherapy may be as effective as traditional regimens in CTCL. High dose-rate (HDR) brachytherapy allows for control of the depth of radiation penetration over complex curved surfaces. This study investigated the role of low-dose HDR brachytherapy for acral CTCL lesions.
