Non-melanoma skin cancer can be prevented with simple laser treatment: study

Health & FitnessNon-melanoma skin cancer can be prevented with simple laser treatment: study

New research suggests that simple Laser treatment The skin can help prevent the growth of basal cell carcinoma and squamous cell carcinoma, which are collectively called keratinocyte carcinoma and are the most common types. Cancer Assessment in the United States. The work was done by a team of researchers from Massachusetts General Hospital, a founding member of Mass General Brigham. Published in Dermatologic Surgery, it reveals an easy-to-implement strategy to protect individuals. Skin health. (Also read: How to spot skin cancer: symptoms, treatment and protection )

Nonablative fractional lasers (NAFL) deliver heat in a fractional fashion that leaves it intact after treatment (unlike ablative fractional lasers that remove the top layer of skin), and they currently treat scarred, sun-damaged skin. , are used to treat age spots. , and more; However, their effectiveness in preventing skin damage is unknown.

For the investigation, Matthew Avram, MD, JD, director of the Mass General Dermatology Laser and Cosmetic Center, and his colleagues studied patients who had previously been successfully treated for facial keratinocyte carcinoma. Such patients have a 35% risk of later developing keratinocyte carcinoma within 3 years and a 50% risk within 5 years.

In the study, 43 patients received NAFL therapy and 52 served as controls and did not receive NAFL therapy. During a mean follow-up of more than 6 years, the rate of development of facial keratinocyte carcinoma was 20.9% in patients treated with NAFL and 40.4% in controls, indicating that approximately half of patients treated with NAFL There was danger.

When controlling for age, sex, and skin type, control patients were 2.65 times more likely to develop a new facial keratinocyte carcinoma than treated NAFL patients. In addition, among patients who developed facial keratinocyte carcinoma, the time to progression was significantly longer in patients treated with NAFL than in untreated patients.

“These findings suggest that treatment of NAFL may have an important role in protecting against later keratinocyte carcinomas,” says Avram. “Although the mechanism of NAFL’s protective effect is not fully understood, it is suspected that NAFL treatment reduces the overall burden of photodamaged keratinocytes and may promote a wound healing response. , which provides a selective advantage to healthy skin cells.”

Avram noted that additional studies are needed to more critically evaluate NAFL’s role in skin cancer prevention, demonstrate the duration of its protective effects, and determine optimal treatment parameters. “Based on this research, patients are encouraged to undergo nonablative laser treatment to help prevent skin cancer if they are at risk or notice abnormalities,” says Avram.
