The Role of Electrochemotherapy in Curative Treatment of Head and Neck Cancer and Advanced Skin Cancer : A Need for New Treatment Protocols?

• BACKGROUND/AIM: Electrochemotherapy (ECT) is a cancer treatment modality where the efficacy of a chemotherapeutic agent is enhanced by an electrical field. It is an established palliative treatment for cutaneous metastases but its role in curative treatment remains mostly undetermined. Studies have previously reported that ECT can be a safe curative treatment in both skin cancer and oral cavity cancer. The primary aim of this case study was to report the long-term results of ECT in curative treatment of four patients with skin or oral cavity cancer. The study also compares two different ECT treatment protocols.PATIENTS AND METHODS: Three patients with oral cavity cancer and one patient with skin cancer were included. One patient had a primary oral tongue cancer and the others had persistent/recurrent tumors after previous treatment. They were treated with ECT either as a primary, adjuvant or salvage treatment with curative intent. The median follow-up period was 60 months.RESULTS: There was one case of local recurrence after treatment in the follow-up period. In the other three patients, no recurrence was recorded. There was one serious adverse airway event. There was a significant difference in the bleomycin dose between the two studied protocols, especially for large tumors.CONCLUSION: ECT can be a safe mono-modality and adjuvant curative treatment in advanced skin cancer and primary and recurrent oral cavity cancer.
