oa Southern African Journal of Gynaecological Oncology - Cobalt-60 is a logical, economical and comparable alternative to Ir-192 : analysis and institutional experience from western India : original research
Objectives : The objective of the study was to examine the dosimetry of intracavitary radiotherapy (ICRT) in carcinoma of the cervix using cobalt-60 (Co-60) as source of ICRT, and as an alternative to iridium-192 (Ir-192).
Design : This was a retrospective study.
Subjects and setting : The study was on 80 ICRT patients attending the radiotherapy department at Maharana Bhupal Government Hospital, Udaipur, India.
Outcome measures : The dosimetry of ICRT was studied retrospectively in 80 related applications. The dose to point A, 60 Gy isodose reference volume, and bladder and rectum maximum and mean doses were defined.
Results : It was found that dosimetry with Co-60 as a brachytherapy source was consistent with the International Commission on Radiation Units (ICRU 38) recommendations.
Conclusion : Co-60 is a logical alternative to Ir-192 in low socio-economic settings when repeated changing of the source is not an option.
