Radiotherapy is an option to treat high-grade laryngeal dysplasia. This study aimed to evaluate the use of intensity-modulated radiotherapy, 55 Gy in 20 daily fractions, in treating this disease.
Acute toxicity was evaluated in all 14 patients treated. In 10 patients, functional voice outcome was measured using the Voice Handicap Index, and the Grade, Roughness, Breath, Asthenia, Strain (‘GRBAS’) scale. These measurements were performed pre-treatment and three months after intensity-modulated radiotherapy.
All but one patient managed to complete radiotherapy. Acute toxicity was significant (one patient developed grade 4 and three patients developed grade 3 dysphagia). Four patients required hospital admission. In 9 out of 10 patients, radiotherapy improved voice quality.
This radiotherapy regimen using intensity-modulated radiotherapy for laryngeal dysplasia is feasible and provided excellent functional outcome, but acute toxicity was significant. Dose de-escalation can be considered in the framework of clinical trials.
To audit the clinical practice of seizure threshold estimation and subsequent stimulus dose adjustment in the electroconvulsive therapy (ECT) clinic. Case notes of patients who had ECT over a six-month period were audited. Results were discussed at an audit meeting and guidelines and training modified appropriately prior to the second cycle of the audit.
Initial dose titration was poor in the first period, but improved in the second. The majority of patients were insufficiently stimulated after missed seizures in both periods and stimulus doses were not being reduced following prolonged seizures.
The audit identified the need for continuing supervision of trainees in addition to clear training and guidelines.
