Efficacy of hypofractionated radiotherapy in patients with non ‐melanoma skin cancer: Results of a systematic review

Summary Radiation oncologists are increasingly tasked with the management of elderly patients with non‐melanoma skin cancer, unsuitable for surgical intervention due to inoperable lesions and/or poor performance status. In this cohort, hypofractionated radiotherapy, delivered either daily, alternative daily or once weekly is highly effective. A systematic literature search was conducted of PUBMED, MEDLINE and EMBASE databases using the algorithm (‘radiotherapy’ OR ‘radiation therapy’ OR ‘brachytherapy’) AND (‘hypofraction’ OR ‘hypofractionated’ OR ‘hypofractionation’) AND (‘skin neoplasms’ OR ‘carcinoma’ OR ‘malignancy’) AND (‘skin’ OR ‘epidermis’ OR ‘epidermal’ OR ‘cutaneous’). Forty relevant publications (1983–2017) encompassing 12,337 irradiated lesions were retrieved. Studies documented a mean age of 71.73 years and male predilection (54.5%). Both external beam radiotherapy and brachytherapy were utilized. Tumour subtype was squamous cell carcinoma (23.5%), basal cell carcinoma (75.2%) or others (1.3%). Irradiated lesions were primary (or denovo) (92.6%), located on the head and neck (95.7%) and received definitive therapy (96.5%). Analysis demonstrated a mean weighted total radiotherapy dose (38.15 Gy), dose per fraction (7.95 Gy) and treatments per week (2.98). Despite significant heterogeneity in the study population, the radiotherapy delivered and follow‐up, local recurrence rate (crude or Kaplan–Meier ana...
