Primary cardiac sarcomas carry a dismal prognosis with no known curati
ve therapy using standard treatment approaches. By its very location,
the possibility of a radical complete resection-the underlying princip
le in the management of any soft-tissue sarcoma-is precluded. While li
terally in a continuous ''blood bath,'' cardiac sarcomas are associate
d with a very high rate of hematogenous metastases. This report descri
bes the management of a case in a 51-year-old white man with a high-gr
ade unresectable cardiac sarcoma who was treated with hyperfractionate
d (twice daily) radiotherapy to a total dose of 7,050 eGy along with a
radiosensitizer, (5'-iodode-oxyuridipne. The patient currently is dis
ease-free and functioning well more than 5 years following this novel
treatment approach.
