Radiation Oncology/RTOG Trials/8003

RTOG 80-03 (LIVER)

• Title: Phase III Comparison of Radiation Alone vs Radiation plus Misonidazole in the Treatment of Liver Metastases
• Objective:
  • I. Compare the frequency and duration of symptomatic relief in patients with liver metastases from a variety of sites treated by radiotherapy alone vs. radiotherapy plus misonidazole.
  • II. Compare the frequency and duration of normalization of liver function in these 2 groups.
  • III. Compare the frequency of decrease in the size of liver metastases by CT scans in the 2 groups.
  • IV. Evaluate the response for each treatment according to site and histology of the primary, performance status, and tumor volume.
  • V. Evaluate the foregoing objective with respect to the length of survival.
• Protocol:
  • Arm 1: RT (whole liver to a dose of 21.0 Gy in 3 Gy/fx)
  • Arm 2: RT + radiosensitization with Misonidazole
• Eligibility: Patients with histologic verification of malignancy other than leukemia, myeloma, or lymphoma, and with hepatic metastases as documented by liver scan and/or CT scan.
• Enrolled: 214 patients
• Conclusion:
  • PMID 3597149 -- A comparison of misonidazole sensitized radiation therapy to radiation therapy alone for the palliation of hepatic metastases: results of a Radiation Therapy Oncology Group randomized prospective trial. (Leibel SA, Int J Radiat Oncol Biol Phys. 1987 Jul;13(7):1057-64.) Conclusion: "The addition of misonidazole did not significantly improve the therapeutic response to radiation therapy in any of the parameters studied."
