Abstract

Electrochemotherapy is a local tumor ablation technique with different effectiveness in different histological types of tumors. In the treatment of breast cancer metastases, the effectiveness of electrochemotherapy is among the lowest. Therefore, combined therapies are needed. The aim of our study was to combine electrochemotherapy with PARP inhibitor olaparib, which would inhibit the repair of bleomycin/cisplatin caused DNA damage and would most likely potentiate the effectiveness of electrochemotherapy. First we demonstrated the effectiveness of electrochemotherapy with bleomycin and cisplatin alone in human breast cancer cell line MCF7 in vitro. Further, we confirmed that effectiveness of electrochemotherapy could be potentiated by combining it with olaparib, but only when bleomycin was used as a cytotoxic drug.
