Superficial radiotherapy (SRT-100) for refractory plantar warts: An alternative noninvasive treatment strategy.

BACKGROUND

Verrucas that occur on the soles of the feet are called plantar warts, most of which can recur repeatedly and are difficult to eradicate. Hypertrophic and refractory plantar warts are often accompanied by pain and discomfort, which cause many inconveniences in patients' daily lives.

AIM

This study aimed to analyze the therapeutic effect of superficial radiotherapy (SRT-100) on refractory plantar warts and further create favorable conditions for the subsequent treatment of this disease with a high recurrence rate.

METHODS

A retrospective analysis was conducted for refractory plantar warts treated with superficial radiotherapy in our outpatient department from January to June 2023.

RESULTS

A total of 30 patients were included in our study (median age, 33 years). The female-to-male ratio was 1:3.29. Two to six months after radiotherapy, all of the warts subsided in 23 (76.67%) patients, most of the warts subsided in 4 (13.33%) patients, 3 (10%) patients did not respond to treatment, and 7 (23.33%) patients had recurrent or new warts after their warts subsided.

CONCLUSIONS

Most patients with refractory plantar warts improved after superficial radiotherapy. Our study presented that men are more susceptible to plantar warts than women, and young and middle-aged people are the main population affected by the disease. Superficial radiotherapy is an effective treatment for refractory plantar warts, which can quickly remove the warts in a short period. It is safe and noninvasive, with minimal adverse reactions. Some patients relapse after the lesion is clear, and superficial radiotherapy can create favorable conditions for the subsequent treatment of viral warts in clinical practice.
