Intracavitary Dosimetry: A Comparison of Doses at Point A and B to Curie-minutes in Cervical Cancer

자궁경부암 고선량율 강내조사치료시 A, B점 선량과 Curie-minutes 단위의 비교

This study, involving thirty-two patients with carcinoma of uterine cervix treated by high dose rate intracavitary irradiation using a remotely controlled afterloading system, compares the doss at point A and 8 with the Curie-minutes prescription. A linear least-square regression analysis was used to compare the two sets of date. Correlation coefficients between doses at points A and B and the Ci-min prescription are 0.92 (p<0.001) and 0.90 (p<0.001), respectively, and linear relationship is observed between these two system. The limitation and significance of the comparison of the two approaches to intracavitary dosimetry is discussed.
