Trial Outcomes & Findings for Phase 2 Total Skin Electron Beam Therapy (TSEBT 12 Gy) in Stage IB-IIIA Mycosis Fungoides (NCT NCT00985140)

NCT ID: NCT00985140

Last Updated: 2017-06-02

Results Overview

After the completion of TSEBT, patients will be followed every 4 weeks until 24 weeks ,and then every 8 weeks for a total of 12 months or until there is disease progression, relapse, or the initiation of a new anti-cancer therapy. The primary endpoint for the trial was the clinical response rate as defined by the modified severity weighted assessment tool (mSWAT) Partial response was defined as 50% improvement in the mSWAT. Complete response was complete disappearance of disease.

Participant Flow

Patients who may be eligible for the trial will be approached by the Investigator and offered participation in the trial. During a clinic visit, the Investigator or co-Investigator will explain the study to the potential subject verbally, and will allow the potential subject ample opportunity to ask questions.

Patients will undergo the following procedures during the screening period: Medical Hx, H\&P, Severity Weighted Assessment Tool (mSWAT) assessment, simulation/set-up for TSEBT, CT if needed, pruritus, hair, and nail assessment, standardized photos (global, nails, head: top, front, sides, back), and two 5 mm punch biopsies from an active MF lesion.

Measure
12 Gy TSEBT
Total skin electron beam therapy will be administered in the Department of Radiation Oncology according to the Stanford six-field technique. Patients will receive a planned total skin dose of 12 Gy fractionated at 2 Gy/cycle (each cycle requiring 2 days of treatment) 4 days each week, for 3 weeks. Discrete tumors may receive additional "boost" treatment not to exceed 12 Gy. .
