Brief Summary

Non-melanoma skin cancer (NMSC) incidence as well as morbidity rates are high in older patients. Surgery is the standard of care. About 5 to 10% of NMSC present high-risk clinico-pathologic features that can increase risk of local recurrence (LR). Adjuvant radiation therapy (ART) is often discussed regarding the risk of local recurrence. Despite the lack of high level evidence, ART is indicated in patients according to unfavorable prognostic factors. ART benefit is generally questioned in regard to the potential degradation of the patient's quality of life (QoL). Currently there is no prospective trial or recommendations that take into account geriatric patients' evaluation and profiles during the management of NMSC. In addition, there is no data that could help to define the subgroup of elderly patients who will benefit from ART in tumors with unfavorable prognostic factors. In terms of ART, multiple fractionation schedules are available, ranging from standard fractionation (45-60Gy in 5-6 weeks) to the extreme hypofractionation (HF) delivering 16-18Gy in one fraction. In routine practice, HF is mainly preferred in elderly patients for more convenience by reducing the number of transports and increase health related quality of life (HRQoL). However, there is no data on the fragility profiles of these patients, nor validating any HF schedule in terms of efficacy, acute toxicity, cosmetic results, and impact on HRQoL. the main ain objective is to evaluate the comparative efficacy of two modalities of Radiotherapy over surgery alone on local tumor control in older patients with Non Melanoma Skin Cancer (NMSC) In current practice, adjuvant radiotherapy is discussed regarding the risk of local recurrence as determined by the existence (or not) of unfavorable prognostic factors. The proposed study will include R0-high risk of CBC and CEC of the skin in elderly patients. There is no risk regarding the design of the trial as the last will respond to two important unknown questions regarding the utility of RT and its fractionation in this population. Moreover, it is an excellent opportunity to collect prospectively geriatric evaluation and HRQoL data that are lacking in the literature for skin cancers. No constraints are seen neither in the design, nor in the potential recruitments.
