Abstract

A fast-neutron-emitting radioisotope, ²⁵²Cf, is being tested in clinical trials of neutron brachytherapy for cervical cancer. The efficacy for histological eradication of bulky stage IB cervical tumors (mean diameter, ∼6 cm) using combined radiation and surgery was studied in 65 patients treated with ¹³⁷Cs or ²⁵²Cf before surgery during 1983-1986. Forty-four patients were treated with ¹³⁷Cs and 21 were treated with ²⁵²Cf at equivalent doses of radiation. Fifteen of the 44 specimens (34%) were positive after ¹³⁷Cs therapy. Only one of the 21 specimens was positive after ²⁵²Cf therapy (P = .025), and that patient was treated in a delayed schedule 21 days after the start of external-beam irradiation rather than early in the course. ²⁵²Cf therapy required a much lower radiation dose and shorter treatment time. The study compared tumor destruction of an identically staged human cervical tumor in situ by direct histological means, using ²⁵²Cf neutron therapy or conventional photon therapy at an identical and equivalent dose adjusted by a relative biological effectiveness of 6.0 for ²⁵²Cf.
