“…This result is not in good agreement with other studies. Other CT based studies who also studied the difference between D 2cc and DICRU, did not find significant difference between the two doses (Pelloski et al, 2005;Kim et al, 2007;Vinod et al, 2011). Our study suggests that the rectal ICRU dose is not an acceptable surrogate to the dose received by 2cc volume of rectum.…”

“…Two studies have reported a good correlation between D 2cc and DICRU of bladder (Kirisits et al, 2005). However, prior to our study, there were also two studies which observed significant difference between the two doses (Pelloski et al, 2005;Kim et al, 2007).…”

“…Several studies have described the differences between the ICRU point doses and volumetric doses for the rectum and bladder (Table 1) [29][30][31]. As shown, the actual difference in the dose between the ICRU rectal point and the D 2cc ranges from 21 to 39 cGy, whereas the difference for the bladder is more variable ranging from 83 to 680 cGy.…”

Objective: Point doses, as defined by the International Commission on Radiation Units and Measurements (ICRU), are classically used to evaluate doses to the rectum and bladder in high dose rate intracavitary brachytherapy (HDR-ICBT) in cervical cancer. Several studies have shown good correlation between the ICRU point doses and the volumetric doses to these organs. In the present study we attempted to evaluate whether this correlation could be used to predict the volumetric doses to these organs. Methods: A total of 150 HDR-ICBT insertions performed between December 2006 and June 2008 were randomly divided into two groups. Group A (n550) was used to derive the correlation between the point and volumetric doses using regression analysis. This was tested in Group B (n5100) insertions using studentised residuals and Bland-Altman plots. Results: Significant correlations were obtained for all volumetric doses and ICRU point doses for rectum and bladder in Group A insertions. The strongest correlation was found for the dose to 2 cc volumes (D 2cc ). The correlation coefficients for bladder and rectal D 2cc versus the respective ICRU point doses were 0.82 and 0.77, respectively (p,0.001). Statistical validation of equations generated in Group B showed mean studentised residual values of 0.001 and 0.000 for the bladder and rectum. However, Bland-Altman analysis showed that the error range for these equations for bladder and rectum were ¡64% and ¡41% of the point A dose, respectively, which makes these equations unreliable for clinical use. Conclusion: Volumetric imaging is essential to obtain proper information about volumetric doses.

“…The doses for these organs were thought to be important and were sometimes more than the doses for the rectum or bladder. 16 Because of the comprehension gained about many things that cannot be perceived by plain orthogonal radiography, CT-based 3D dosimetry may be essential for the future progress of intracavitary brachytherapy.…”
