Radiation Oncology/Melanoma/Hyperthermia

Hyperthermia and Cutaneous Melanoma Please see the Hyperthermia section for further information on hyperthermia Randomized ESHO 3-85 Randomized multicenter. 70 patients with 134 recurrent melanoma lesions. Treated with RT alone (24/3 or 27/3) or RT + Hyperthermia (43C for 60 min). F/U 3-72 months 8676005 -- "Hyperthermia as an adjuvant to radiation therapy of recurrent or metastatic malignant melanoma.

European Society for Hyperthermic Oncology" (Overgaard J, Lancet 1995 Mar 4;345(8949):540-3). Only 14% received target HT due to difficulties with equipment 2-year LC: RT alone 28% vs. RT+HT 46% (SS); RT 24/3 25% vs. 27/3 56% (SS) Toxicity: not increased with HT Retrospective Graz, 2003 (Austria) 16296154 -- "Efficacy of superficial and deep regional hyperthermia combined with systemic chemotherapy and radiotherapy in metastatic melanoma."

Best results in cutaneous or retroperitoneal mets Conclusion: LC can be achieved in metastatic melanoma with HT Jefferson, 1993 (1980-1988) 8416885 -- "Hyperthermia and radiation in advanced malignant melanoma."

Hyperthermia given twice-weekly Response: 12/33 CR, 17/33 PR.

RT given as 6-8 Gy once a week, or 4-5 Gy twice a week Response: CR for RT+HT 50% (if 8 Gy/fx CR 83%), CR for RT alone 38% Toxicity: enhancement of acute skin reaction, but not clinically significant Review MC Virginia, 1996 8914205 -- "Role of radiotherapy and hyperthermia in the management of malignant melanoma."
