Description
INTRODUCTION: Excisional and destructive procedures remain first-line therapy for basal cell carcinoma (BCC) and squamous cell carcinoma (SCC) but often result in visible scarring, highlighting the need for effective nonsurgical options such as: red light photodynamic therapy, CO2 laser, Nd:YAG, and pulsed dye with favorable cosmetic outcomes.
OBJECTIVE: To evaluate the effectiveness and cosmetic outcomes of nonsurgical treatment modalities including red-light photodynamic therapy, CO₂ laser, Nd:YAG laser, and pulsed dye laser in the management of BCC and SCC.
METHOD: A literature search was conducted using PubMed/MEDLINE to identify published case reports describing nonsurgical treatments for basal cell carcinoma, including photodynamic therapy and laser-based modalities. Relevant reports were reviewed for patient characteristics, treatment parameters, clinical outcomes, and cosmetic results. Extracted data were qualitatively synthesized to highlight treatment efficacy and safety profiles.
RESULTS: Laser-based therapies demonstrated variable recurrence rates in the treatment of basal cell carcinoma. Nd:YAG laser therapy across seven studies including 3,286 BCCs showed a 3.1% recurrence rate with a mean follow-up of 7.9 years. CO₂ laser treatment across ten studies including 904 BCCs demonstrated a 9.4% recurrence rate with a mean follow-up of 2.1 years. Pulsed dye laser (PDL) across eight studies including 206 BCCs showed a 38% recurrence rate with a mean follow-up of 0.5 years.
In a randomized phase III study of 187 participants, 145 received red-light photodynamic therapy (PDT) with 10% aminolevulinic acid (ALA) gel and 42 received vehicle. Clinical clearance of the main target lesion after the final PDT cycle was 83.4% with 10% ALA gel compared with 21.4% with vehicle. Histological clearance was 75.9% vs 19.0%. Additionally, 88.1% in the ALA 10% group reported very good cosmetic outcomes.
CONCLUSION: These findings support red-light photodynamic therapy with 10% ALA gel as an effective, well-tolerated non-surgical option for superficial basal cell carcinoma, particularly for patients with multiple or larger lesions, tumors in low-risk locations, or those who wish to avoid surgery. Furthermore, photodynamic therapy may serve as a useful adjunct to surgical management by decreasing tumor burden and potentially minimizing the extent of tissue excision required. Although laser-based therapies such as Nd:YAG have demonstrated favorable recurrence rates in observational studies, red-light PDT offers best cosmetic outcomes. CO₂ laser therapy demonstrates moderate recurrence rates with shorter follow-up periods. In contrast, pulsed dye laser (PDL) has been associated with substantially higher recurrence rates in currently available studies.
