Abstract

Abstract 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.

钴-60是一种合理的、经济的、可与Ir-192相媲美的替代品:来自印度西部的分析和制度经验

摘要目的:本研究的目的是研究使用钴-60 (Co-60)作为ICRT源并替代铱-192 (Ir-192)的宫颈癌腔内放疗(ICRT)的剂量学。设计:这是一项回顾性研究。研究对象和环境:研究对象为印度乌代普尔Maharana Bhupal政府医院放疗部的80名ICRT患者。结果测量:回顾性研究了80个相关应用的ICRT剂量学。定义了到达A点的剂量、60 Gy等剂量参考体积、膀胱和直肠的最大剂量和平均剂量。结果:发现以Co-60作为近距离放射治疗源的剂量测定符合国际放射单位委员会(ICRU 38)的建议。结论:在低社会经济环境中，当重复改变来源不是一个选择时，Co-60是Ir-192的合乎逻辑的替代品。
