Gynae Flashcards
Types of vaginal brachy applicators (and role of each):
Vaginal cylinder (often segmented) - best for symmetric brachy
Multichannel cylinder - For asymmetric dose (also e.g. to avoid bowel loop 80Gy)
Tandem and ovoid or ring applicator (or tandem or ring): Cervix cancer
Combined interstitial intracavity devices.
Rotte applicator (a 2 channel tandem thing where both channels can go into the uterine cavity) - in rare case of intact uterus.
Key scheduling considerations for ChemoRT + brachy boost cervix patients
Duration of EBRT + brachy should aim to not exceed 56 days.
Recent evidence suggests delivery within 49 days may be beneficial.
It is recommended that brachytherapy is scheduled towards the end, or after completion, of the EBRT course.
Chemotherapy and EBRT should be omitted on the days of brachytherapy.
