Intracavitary radiation therapy is an option when palliative treatment is being considered for women who are not surgical candidates or who have other medical contraindications.
If the depth of invasion is less than 3 mm, no capillary lymphatic space invasion is noted, and the frequency of lymph-node involvement is sufficiently low, external-beam radiation therapy is not required. One or two insertions with tandem and ovoids for 6,500 mg to 8,000 mg hours (100–125 Gy vaginal surface dose) are recommended.[10]
