Clinical and dosimetric consequences of imperfect applicator insertion in cervical cancer brachytherapy.

Purpose: This study analyzes clinical consequences and dosimetric variations after imperfect brachytherapy insertions. It examines treatment decisions after such insertions in patients having difficult anatomy, which leads to good subsequent insertions with acceptable dose volume parameters.

Material And Methods: We reviewed images of all insertions performed during last one year and sorted faulty ones out.

Comparison of dose volume parameters evaluated using three forward planning - optimization techniques in cervical cancer brachytherapy involving two applicators.

Purpose: This study is intended to compare dose-volume parameters evaluated using different forward planning- optimization techniques, involving two applicator systems in intracavitary brachytherapy for cervical cancer. It looks for the best applicator-optimization combination to fulfill recommended dose-volume objectives in different high-dose-rate (HDR) fractionation schedules.

Material And Methods: We used tandem-ring and Fletcher-style tandem-ovoid applicator in same patients in two fractions of brachytherapy.
