  • Title: Neutron and gamma dose distribution for tandem, tandem and ovoid and plaque for intracavitary 252Cf therapy of cervix carcinoma.
    Author: Maruyama Y, Tai DL, Beach JL.
    Journal: Radiat Med; 1983; 1(3):230-6. PubMed ID: 6390538.
    Abstract:
    252Cf was used to treat tumors of the cervix in an ongoing clinical trial. Tandem and ovoids were used as well as a combination of single and multiple applications. Dosimetric analysis of these treated cases revealed the patterns of neutron dose rate and neutron/gamma ray dose ratios which were achievable using a variety of loading arrangements. Although pelvic tumor reference points and tissue dose was in general similar whether a tandem or tandem plus ovoids were used, vaginal dose was increased over two-fold or more by the use of vaginal applicators and sources. This indicates that a variety of individualized arrangements for different clinical presentations can be used for brachytherapy of gynecological pelvic neoplasm.
