Calcipotriol Boosts Effectiveness of Daylight Photodynamic Therapy for Actinic Keratoses: Study Finds

The combination therapy was well tolerated, with minimal discomfort reported among participants. This underscores the potential of calcipotriol as a safe and effective adjunct to DL-PDT for managing AKs.

The study led to the following findings:

• Significant AKASI Score Reduction: Patients pre-treated with calcipotriol (CAL) showed a greater reduction in AKASI scores compared to the control group, indicating enhanced treatment efficacy.
• Improved DL-PDT Effectiveness: CAL pre-treatment boosted the therapeutic impact of daylight photodynamic therapy (DL-PDT) for actinic keratoses.
• Well-Tolerated Treatment: The combination therapy was safe and effective, with minimal patient discomfort.

These findings highlight the clinical benefits of incorporating calcipotriol into AK treatment regimens, potentially improving lesion clearance and reducing the risk of progression to SCCs. Further research could help establish this approach as a standard practice, offering a more effective solution for individuals at risk of actinic damage and non-melanoma skin cancers.

"The findings indicate that integrating calcipotriol into the treatment regimen enhances AK clearance and may reduce the risk of progression to squamous cell carcinoma, offering a promising approach for improved skin cancer prevention," the authors concluded.
