Description of intervention(s) / exposure
Other interventions - Physical exam

Part 1 - Participants will have endometrioid adenocarcinoma histological diagnosis with planned surgical treatment including hysterectomy in combination with SLN biopsy.

Part 2 - Participants will have undergone surgery and bilateral sentinel lymph node mapping (negative for malignancy)

Other interventions: Physical exam
Part 2 participants will be prospectively followed clinically for relapse for 30 months from the date of surgery for physical examination at post-ops visits.

Key exclusion criteria
- Extrauterine disease, or gross lymph node involvement, or cervical invasion suspected
on pre-operative imaging studies and physical examination (disease not uterine
confined clinical stage > I)

- Contraindication for SLN mapping

- The planned treatment is not surgery, or the surgical treatment does not include
hysterectomy in combination with SLN biopsy

Part 2 Inclusion Criteria

Patients will be classified in the study cohort (part 2; n=182) according to surgical
treatment received, final post hysterectomy and staging pathologic report, and planned
adjuvant treatment. The inclusion criteria are specified below.

Study Cohort (part 2 n=182)

A patient will be enrolled in the study cohort (part 2) if all the following criteria are

- At surgery, the patient must undergo:

- Hysterectomy with removal of the adnexa

- Bilateral pelvic SLN mapping (bilateral sentinel nodes are negative for

- On the final pathologic report, the patient must have a diagnosis of:

- Stage I intermediate-risk endometrial endometrioid cancer (Grade 1 or Grade 2
with = 50% myometrial invasion or Grade 3 with <50% myometrial invasion)

- Negative pelvic peritoneal cytology

- Adjuvant treatment as recommended by the multidisciplinary team must be as follows:

- No adjuvant treatment, or

- Intravaginal radiation only

Part 2 Exclusion Criteria

- There is intra-operative detection of extra-uterine disease or grossly involved lymph

- Presence of any positive pelvic nodes including micrometastasis and isolated tumor
cells (ITC)

- Hysterectomy is not performed

- Failed unilateral or bilateral SLN mapping

- Patient undergoes a complete unilateral or bilateral pelvic lymphadenectomy

- Patient undergoes a radical type C hysterectomy

- Stage IA endometrioid cancer Grade1 or 2 and myometrial invasion <50%

- Stage IB Grade 3 endometrioid cancer

- Non-endometrioid histology: Serous, clear cell, carcinosarcoma, undifferentiated, or
de-differentiated histology noted on final hysterectomy pathology

- Empty unilateral or bilateral sentinel lymph nodal packet(s)

- Positive peritoneal cytology

Brief summary
This study is being done to find out how often endometrial cancer recurs after the standard
treatment as well as how often the standard treatment results in a lymphedema.
