ABSTRACT
BACKGROUND: Electrochemotherapy (ECT) combines chemotherapy and electroporation to increase drug uptake. Its role in cutaneous melanoma metastasis treatment is not well defined; indeed, few studies have been reported, without complete follow-up data. AIM: To prospectively evaluate clinical activity and tolerability of ECT with i.v. bleomycin, and to analyze the response increase associated to repeated sessions, in the largest series of cutaneous melanoma metastases reported to date (n = 233). PATIENTS AND METHODS: 14 stage III relapsed/refractory patients were enrolled according to European Standard Operating Procedures of Electrochemotherapy (ESOPE) guidelines and treated under general sedation using the Cliniporator(TM) pulse generator. RESULTS: A response was obtained in 13/14 patients (93%) after the first ECT, with a complete regression (CR) in 7 (50%). Seven patients underwent a second and three a third ECT on newly appearing and residual lesions, all achieving a response. Overall, a response was obtained in 93% metastases, with lower response rates in >1 cm(2) lesions. The CR rate was 58%; none of the CR nodules relapsed. The repeated ECT sessions gave rise to a new response in 21/29 (72%) re-treated lesions. The local tumor control rate was 74.5% at 2 years. CONCLUSION: ECT is a safe procedure, easily performed in terms of toxicities and cost-effectiveness ratios, and constitutes a therapeutic tool for relapsed/refractory cutaneous melanoma patients. The repeated ECT sessions are associated with a response increase in re-treated lesions which could allow to overcome the reduced activity in >1 cm(2) sized metastases.

On the basis of personal experience of many patients affected by neoplastic lesions, the conviction that the assistance provided to a terminal cancer patient in the hospital ward is deficient and takes no account of the medical, emotional, social and spiritual needs of the patient and his family, is expressed. It would be advisable for assistance to terminale patients to be supplied in adequate centres operating on multidepartmental bases, with the participation of experts in antalgic treatment and psychological problems.
