Four patients with massive cavernous hemangioma of the liver were treated with 6 Mev X-ray, and favorable results were obtained in 3. Patient 1 was treated with a total tumor dose of 940 rads without response. The 2nd patient was given a total tumor dose of 1900 rads over 54 days, with a daily dose of 50 to 100 rads. Although the hemangioma regressed after treatment, the response was transient. A total tumor dose of 2940 rads was given over 41 days with a daily dose of 100 to 200 rads as a second course, and the hemangioma regressed with no sign of reenlargement. Patients 3 and 4 were given 150 to 200 rads every other day to a total of about 3000 rads, with a satisfactory response. Follow-up studies showed the latter 3 patients to be well 8, 5, and 4 years after radiotherapy, respectively.
