Necrosis-inducing anticancer drugs enhance high-mobility group box 1 (HMGB1) release during cell necrosis, and HMGB1-induced autophagy in skeletal muscle induces muscle atrophy. We evaluated the efficacy of magnetic hyperthermia therapy (MHT) using a low-energy magnetic field and self-controlled heating elements in tumor treatment. MHT-induced apoptosis by heating mouse subcutaneous tumors at 43°C using a heat-controlling iron-aluminum (Fe-Al) milling alloy. In contrast, MHT using Fe line-induced necrosis by heating to approximately 100°C. Furthermore, MHT with Fe-Al milling alloy reduced stemness. In hyperthermia using age line or Fe-Al milling alloy, both of them provided histological degeneration in skeletal muscle; however, qualitative differences were observed. MHT using Fe-line induced pronounced autophagy, decrease of myosin heavy chain content, and increase in serum HMGB1. In contrast, MHT using Fe-Al milling alloy induced heat shock protein 90 but no autophagy and decreased serum HMGB1. Therefore, MHT using Fe-Al milling alloy might be a good method for local treatment of tumors to reduce skeletal muscle atrophy.
