Gyn Onc Flashcards
Point A for Radiotherapy for carcinoma of the cervix. How much Rads for local advanced disease?
2 cm above level of external os and 2cm lateral to the midline (point of crossover of artery over ureter)
Point B for Radiotherapy for carcinoma of the cervix. How much Rads?
3 cm lateral to point A (position of obturator nodes) Aim to deliver 5500 to 6500. Rads to Point B depending on the extent of parametrial/sidewall disease
High risk HPV subtypes
16, 18, 31, 33, 35, 45
Describe the histological architecture of Endometrial Intraepithelial Neoplasia (EIN)
Increased glandular density w/ atypia
Risk of malignancy w/ Endometrial Intraepithelial Neoplasia (EIN)
formerly simple/complex hyperplasia w/ atypia (formerly 10/30%)
30-50%
Types of Endometrial Cancer
Type I- Endometriod, 75% of endometrial cancer, global process, unopposed estrogen, better prognosis
Type II- Clear Cell, Papillary Serous. High grade, poorer prognosis, more focal in origination
How is staging for uterine cancer performed?
Surgical staging-remove uterus, cvx, adnexa, pelvic and para aortic nodes and pelvic washings
One of most important prognostic factors for endometrial carcinoma?
Presence of extra uterine disease
What percent of patients w/ surgery for an atypical endometrial hyperplasia will have an endometrial cancer at final pathology?
40% of patients
Criteria for patient selection for Medical Management of Endometrial Carcinoma?
- Pre-menopausal w/ strong desire to preserve uterus for fertility
- Poor candidate for major operation due to medical co-morbidities
Medical Management of Endometrial Cancer
- Medroxyprogesterone or Megestrol
- Progesterone-containing IUD
