Is vaginal brachytherapy typically recommended after hysterectomy for stage 1B endometrial cancer with clean margins and no lymph node involvement?
Yes, it can be normal to receive vaginal brachytherapy even with these favorable findings. While some people with stage 1 endometrial cancer only need surgery, the decision depends on several risk factors beyond just the stage.
Brachytherapy may be recommended if you have certain risk factors for recurrence, including:
* Cancer that has spread to deeper layers of the endometrium or myometrium (which defines stage 1B)
* Age over 60
* Higher grade tumors
* Specific cancer types like serous or clear cell carcinoma
Even with clean margins and no lymph node involvement, the depth of invasion into the uterine muscle (the "B" in stage 1B) is itself a risk factor. Studies show that most recurrences in early-stage endometrial cancer happen in the vagina, particularly in the vaginal cuff area.
Vaginal brachytherapy helps lower the chance of cancer returning in vaginal tissue. About 15 to 20 percent of people with endometrial cancer may experience recurrence after hysterectomy, which is why your care team may recommend this additional treatment as a precaution.
It's worth discussing with your radiation oncologist why they're recommending brachytherapy in your specific case and what other risk factors they're considering.
