Standard management of melanoma includes procedures such as surgical removal and radiation therapy. However, in some cases, these treatments may be difficult to implement. Recently, laser therapy has emerged as an alternative treatment option. This article explores different types of lasers used in melanoma therapy, with a particular focus on lentigo maligna.
Carbon dioxide laser ablation
Carbon dioxide (CO2) laser ablation has shown potential as an alternative treatment for lentigo malignant, especially when standard treatments such as surgical removal and radiation therapy are impractical.
Efficiency and Recurrence
One of the main advantages of CO2 laser ablation is the reduced recurrence rate, which is around 6.7%, compared to 29% for radiation therapy. This makes laser ablation an attractive choice for many patients and doctors.
Procedure
The procedure uses a focused laser beam to remove cancerous cells while minimizing damage to surrounding healthy tissue. It can be used under both local and general anesthesia and has a relatively low complication rate.
Other Lasers in the Therapy of Lentigo Maligna
Other studies have demonstrated the effectiveness of different types of lasers, such as ruby laser, argon and alexandrite, in lentigo maligna.
Lasse Ruby
Lasse ruby is effective in treating superficial and deep pigmentation, with good penetration and a lower risk of scarring.
Argon laser
Argon laser is often used to treat superficial lesions. It has good affinity for melanin pigments, which makes it effective in the selective removal of malignant cells.
Alexandrite laser
The alexandrite laser is known for its ability to treat a wide range of pigmented lesions. It can be used on different skin types and has shown promise in managing lentigo malignant.
Conclusion
Laser therapy offers a new and promising alternative in the treatment of lentigo malignant and other types of melanoma. With a significantly lower recurrence rate than radiation therapy and with various types of lasers to choose from, laser therapy is becoming an integral part of the melanoma treatment landscape. Further research and clinical trials will help optimize these techniques and establish their definitive role in the management of melanoma.
