Abstract

Intracavitary Californium‐252 combined with whole‐pelvis photon radiotherapy was tested as the sole form of treatment for 22 patients with Stage IB carcinoma of the cervix. Californium‐252 (Cf) is a fast neutron‐emitting radioisotope currently being tested in trials of neutron brachytherapy (NT). The outcomes of the treated group of patients were traced for local tumor control, survival, patterns of failure, and complications. The Cf intracavitary therapy combined with whole‐pelvis photon radiotherapy resulted in 95% 2‐year and 91% 5‐year actuarial survival. There were 9% Grade II‐III complications by the Stockholm scale and 4% local failures. These results were obtained in an early clinical trial with a group of largely poor‐risk patients with tumors of mean diameter of 4.3 cm.
