title: Electrochemotherapy for the Treatment of Unresectable Locoregionally Advanced Cutaneous Melanoma: A Systematic Review.
abstract: Electrochemotherapy is a therapeutic option for the treatment of cutaneous and subcutaneous metastases from melanoma and other tumors. The procedure consists of the administration of anticancer drugs followed by locally applied electrical impulses to achieve an effect known as electroporation, which facilitates entry into the cytosol of drugs that cannot cross the cell membrane. The aim of this review is to evaluate the evidence that supports the use of electrochemotherapy as a therapeutic strategy in melanoma. We conducted a qualitative systematic review of the literature using advanced searches of bibliographic databases and full text reviews. Seven studies (3 systematic reviews and 4 cases series) were selected. The quality of the evidence was not good, but the coincidence of results for certain variables supports their consistency. Results of the meta-analyses favored electrochemotherapy over chemotherapy. Electrochemotherapy appears to be an effective procedure for the local treatment of malignant tumor nodules (evidence of intermediate or low quality). This inexpensive method is simple to apply, well tolerated, and achieves objective responses under certain circumstances. There is no evidence that electrochemotherapy alters the natural course of the disease and it should therefore be considered a palliative treatment. With an evidence level of 1- (minus), electrochemotherapy can be recommended for the palliative treatment of unresectable, locoregionally advanced melanoma (grade B recommendation).
