Progress in Californium-252 Neutron Brachytherapy
The potential of using Cf-252 to treat cancer patients was first described by Shlea and Stoddard in 1965 as a source of neutrons using brachytherapy procedures [Stoddard, 1986]. In the late 1960’s and early 1970’s, the United States and England initiated human clinical trials of Cf-252 neutron brachytherapy (NBT) for treating patients of various cancer types. These earlier trials treated only v...
متن کاملA Monte Carlo Study on the Effect of Various Neutron Capturers on Dose Distribution in Brachytherapy with 252Cf Source
Background: In neutron interaction with matter and reduction of neutron energy due to multiple scatterings to the thermal energy range, increasing the probability of thermal neutron capture by neutron captures makes dose enhancement in the tumors loaded with these materials. Objective: The purpose of this study is to evaluate dose distribution in the presence of 10B, 157Gd and 33S neutron...
متن کاملClinical report on external irradiation combined with californium-252 neutron intraluminal brachytherapy for cervical carcinoma treatment.
AIMS AND BACKGROUND Neutron rays produce high linear energy transfer radiation, which has particular radiobiological characteristics. The aim of the study was to observe the curative effects and complications of external irradiation combined with californium-252 (252Cf) neutron intraluminal brachytherapy for treatment of cervical carcinoma. METHODS AND STUDY DESIGN From December 2000 to Decem...
متن کاملSecond malignancies following conventional or combined 252Cf neutron brachytherapy with external beam radiotherapy for breast cancer
We retrospectively evaluated the risk of second malignancies among 832 patients with inner or central breast cancer treated with conventional external beam schedule (CRT group), or neutron brachytherapy using Californium-252 (²⁵²Cf) sources and hypofractionated external beam radiotherapy (HRTC group), between 1987 and 1996 at the Institute of Oncology, Vilnius University. Patients were observed...
