Effectiveness and Safety of Treatment with Neodymium:YAG Laser 1064 nm in Patients with Classic and Epidemic Kaposi Sarcoma

Kaposi’s sarcoma (KS) is a vascular neoplasm Herpes Virus 8 (HHV8), which can affect the skin, mucous membranes and viscera. There is currently no standard treatment for KS; this study evaluated the efficacy and safety of Neodymium:YAG (Nd:YAG) laser 1064 nm treatment in patients with classic and HIV-associated KS. 15 patients with classic KS (group A) and 15 with epidemic KS (group B), with exclusively cutaneous localization, were treated with Nd:YAG laser 1064 nm. Four treatment sessions were performed at 4 weeks intervals. 24/30 (80%) of treated patients underwent clinical improvement. Better results have been obtained in HIV-positive patients, especially in terms of reduced lesion size and the flattening of elevated lesions. The 1064 nm Nd:YAG laser is effective and safe in the treatment of classic and epidemic KS, especially in patients with symptomatic, slow-progressing local disease, where other treatment options may be inappropriate.
