Midline shield for radiation therapy of carcinoma of the uterine cervix: Should it be “midline” or “individualized”?

The Variability of Applicator Position among High Dose Rate Intracavitary Brachytherapy Applications in Cervical Cancer Patients Treated with Ring & Tandem Applicators

“…A few studies have investigated the reproducibility of applications in cervical carcinoma brachytherapy with HDR applicators 1,2,[4][5][6][7][8] . Most of these studies evaluated tandem and ovoid applications and usually compared the applications in terms of dosimetry 2,[4][5][6][7][8] . Only two studies in the literature examined the positional variability of R&T applications 1,2 .…”

Positional Variability of a Tandem Applicator System in HDR Brachytherapy for Primary Treatment of Cervix Cancer

“…In a previous paper, Datta et al [3] compared standard midline shielding (SMLS) to individualized midline shielding (IMLS) according to the uterine geometry with respect to dose homogeneity at point A in 20 patients. The dose profiles of IMLS were compared with the corresponding dose profile of a 5 cm SMLS and were found to be dependent on the positional variation of point A right (AR) and point A left (AL) with respect to the midline.…”
