What is your dose-fractionation for cylinder-based vaginal cuff HDR brachytherapy for an isolated vaginal cuff recurrence after whole pelvis EBRT with residual thickness of disease <5 mm?

What is your typical treatment depth prescribed to? What length of vaginal mucosa do you typically treat?

I usually prescribe 5Gy x5. I don't prescribe to a fixed thickness but treat based on residual thickness seen on MRI using multichannel applicator.I lesion at apex then treat upper 2-3 cm of vagina Here is out paper describing technique and outcome in detailhttps://www.ncbi.nlm.nih.gov/pub...

In tha past we usually prescribed at 0.5 cm depth LDR or HDR biologically equivalent doses. As we have evolved to image-guided BT, I agree with @Sushil Beriwal's answer and @Brian Gebhardt's paper recommendation @Carlos A. Perez
