EMBRACE data suggest HRCTV dose needs to be increased by 5 Gy for each week delay beyond 50 days to counter the downside of delay. We try to do that using hybrid applicator but total dose is still limited by OAR dose and we try to push as much as we can. (HRCTV to 90-95 Gy)
How would you proceed when a cervical cancer undergoing brachytherapy has exceeded the rectal dose but not met the target dose?

Rectal dose and target dose have range. Preferred rectal dose for D2cc < 65 Gy but can accept up to D2cc < 75 Gy, provided you understand expected risk of complications with increased dose. Preference would be to do hybrid applicator with 3D imaging to optimize HRCTV and OAR.
