Introduction:

non-melanoma skin cancer (NMSC) is the most common cancer in humans. Surgery in these patients has been considered the "gold standard", but it may not be the appropriate option, especially in areas where it may cause functional or cosmetic morbidities due to tissue loss.

Objective:

To evaluate cosmetic outcomes in patients with skin carcinomas in the nasal ala, dorsum and/or tip of the nose treated with surface radiotherapy.

Methods:

an observational, longitudinal, retrospective study was conducted in patients with skin carcinoma treated with superficial radiotherapy with SENSUS SRT-100 TM during the period September 2017 to December 2021 in Pinar del Río. The universe consisted of 34 patients, the sample consisted of 28, obtained by non-probabilistic purposive sampling according to the established inclusion and exclusion criteria.

Results:

the average age recorded was over 60 years, male gender, skin colour white and the predominant histological type was basal cell carcinoma. Conventional fractionation schedules were used in more than 70 % of cases. The most frequent late adverse effects were mild atrophy of the nasal cartilage and hypopigmentation of the skin, classified as toxicity grade 0/1 linked to an excellent/good cosmetic outcome in 89,7 %.

Conclusions:

The cosmetic results obtained were considered excellent/good, reporting low toxicity profile and low local recurrence rates, demonstrating safety and quality through the use of surface radiotherapy as a treatment option in patients with skin carcinomas.
