Objective:

To evaluate whether the adjunctive use of a prebiotic and panthenol-containing repair balm (BB5+) improves tolerability and treatment adherence during topical 5-fluorouracil therapy for actinic keratoses, addressing a significant clinical need.

Key Findings:
  • Adjunctive BB5+ did not significantly improve treatment completion rates (insert specific statistical results).
  • BB5+ reduced the severity of local skin reactions.
  • Quality of life improved, particularly for patients undergoing facial field therapy.
Interpretation:

The use of BB5+ may enhance tolerability of topical 5-FU therapy without compromising treatment exposure, suggesting that barrier repair strategies can improve patient experience and should be considered in clinical practice.

Limitations:
  • The study did not achieve significant improvements in treatment completion rates, which may limit the applicability of the findings.
  • The assessment of local skin reactions may have variability due to subjective reporting.
Conclusion:

Adjunctive supportive strategies like BB5+ may provide a simple and accessible means to enhance patient experience during field therapy for actinic keratoses, highlighting the need for further research in this area.
