[Local immunotherapy. Alternative therapy for malignant cutaneous lesions (demonstration on 30 patients with...

Experimental data in animal models and clinical experience with a systemic immunotherapeutic approach in patients with tumours were the determining factors in the decision to test the local effect of this form of therapy on primary and secondary malignant lesion of the skin. The antitumour effect of local immunotherapy seems to be based on the induction of a cell-mediated immune challenge reaction in close contact with the malignant neoplasm. A trial of local immunotherapy was undertaken in 30 patients with melanoma with local recurrence of the primary tumour or multiple metastases involving the skin. The therapeutic indications and clinical response are discussed.
