The Results of Low-Dose Total Skin Electron Beam Radiation Therapy (TSEB) in Patients With Mycosis Fungoides From the UK Cutaneous Lymphoma Group.

PURPOSE: Total skin electron beam radiation therapy (TSEB) is a very effective treatment of mycosis fungoides. Following reports of similar durations of response to lower doses of TSEB, a low-dose schedule of TSEB was introduced in the United Kingdom. METHODS AND MATERIALS: A protocol of 12 Gy in 8 fractions over a period of 2 weeks was agreed on by use of the Stanford University technique. Data were collected prospectively, and the results were analyzed according to the European Organisation for Research and Treatment of Cancer-International Society for Cutaneous Lymphomas endpoints (EORTC-ISCL). Toxicity was scored according to CTCAE v4.0 (Common Terminology Criteria for Adverse Events version 4.0). RESULTS: One hundred three patients received treatment, with a median follow-up period of 20.6 months (range, 3.3-53 months). Of these patients, 54 had stage IB disease, 33 had stage IIB, 12 had stage III, and 4 had stage IV. The median age was 68 years (range, 26-91 years). The complete response rate was 18%, the partial response rate was 69%, stable disease was present in 8%, and progression on treatment was found in 5%. In the patients who had a complete response, the median time to relapse was 7.3 months. The median response duration was 11.8 months. Median progression-free survival for all patients was 13.2 months. It was significantly longer, at 26.5 months, in patients with stage IB disease compared with 11.3 months in patients with stage IIB (P=.003; hazard ratio, 2.66) and 10.2 months in patients with stage III (P=.002; hazard ratio, 4.62). The treatment was well tolerated with lower toxicity than higher-dose schedules. CONCLUSIONS: The low-dose TSEB schedule of 12 Gy in 8 fractions over a period of 2 weeks is well tolerated and is an effective option for patients with mycosis fungoides.

A randomised controlled trial of Caphosol mouthwash in management of radiation-induced mucositis in head and neck cancer.

PURPOSE: This phase III, non-blinded, parallel-group, randomised controlled study evaluated the efficacy of Caphosol mouthwash in the management of radiation-induced oral mucositis (OM) in patients with head and neck cancer (HNC) undergoing radical (chemo)radiotherapy. PATIENTS AND METHODS: Eligible patients were randomised at 1:1 to Caphosol plus standard oral care (intervention) or standard oral care alone (control), stratified by radiotherapy technique and use of concomitant chemotherapy. Patients in the intervention arm used Caphosol for 7weeks: 6weeks during and 1-week post-radiotherapy. The primary endpoint was the incidence of severe OM (CTCAE ⩾grade 3) during and up to week 8 post-radiotherapy. Secondary endpoints include pharyngeal mucositis, dysphagia, pain and quality of life. RESULTS: The intervention (n=108) and control (n=107) arms were well balanced in terms of patient demographics and treatment characteristics. Following exclusion of patients with missing data, 210 patients were available for analysis. The incidence of severe OM did not differ between the intervention and control arms (64.1% versus 65.4%, p=0.839). Similarly, no significant benefit was observed for other secondary endpoints. Overall, compliance with the recommended frequency of Caphosol was low. CONCLUSION: Caphosol did not reduce the incidence or duration of severe OM during and after radiotherapy in HNC.
