Is this trial a fit for you?

Likely a good fit

Ideal candidates for this study are women aged 18 and older with a confirmed diagnosis of endometrioid adenocarcinoma who are eligible for surgical treatment.

Probably not a fit

Patients with extrauterine disease or those who have received prior treatments such as neoadjuvant chemotherapy or radiotherapy may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This observational study aims to assess the recurrence rates of endometrial cancer and the incidence of lymphedema following standard treatment in women diagnosed with endometrioid adenocarcinoma. Participants will undergo physical examinations and be monitored for outcomes related to their treatment. The study focuses on women who are suitable candidates for surgery and have specific eligibility criteria regarding their cancer stage and treatment history.

Why it matters

Potential benefit: If successful, this study could provide valuable insights into the long-term effects of standard treatment for endometrial cancer, potentially improving patient management and outcomes.

How similar studies have gone: Other studies have explored similar observational approaches in cancer treatment outcomes, indicating a potential for valuable findings, although this specific focus may be novel.

* No history of second primary cancer (invasive or in situ) within the past 5 years, not including non-melanoma skin cancer

Eligibility 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 (n=182)

A patient will be enrolled in the study cohort if all the following criteria are met:

* At surgery, the patient must undergo:

  * Hysterectomy
  * Bilateral salpingo-oophorectomy, unless already performed (including allowing unilateral salpingo-oophorectomy if unilateral salpingo-oophorectomy already performed)
  * Bilateral pelvic SLN mapping (bilateral sentinel nodes are negative for malignancy)
* 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, including non-invasive disease)
  * Negative pelvic peritoneal cytology
* Adjuvant treatment as recommended by the multidisciplinary team must be as follows:

  * No adjuvant treatment, or
  * Intravaginal radiation only

Eligibility Exclusion Criteria

* There is intra-operative detection of extra-uterine disease or grossly involved lymph nodes
* Presence of any positive pelvic nodes including micrometastasis and isolated tumor cells (ITC)
* Hysterectomy is not performed
* Bilateral salpingo-oophorectomy is not performed, unless already performed (unilateral salpingo-oophorectomy is allowed if unilateral salpingo-oophorectomy already 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
