Stage II Endometrial Cancer

Current Clinical Trials

Uterine serous histologies have higher rates of recurrence than do other stage II endometrioid carcinomas. The outcomes in institutional case series that utilize a policy of adjuvant carboplatin plus paclitaxel, occasionally including radiation therapy, for this histologic subtype have been published and form the basis of management guidelines.[1,2] The GOG-0249 (NCT00807768) trial is comparing this chemotherapy regimen to pelvic radiation.

Standard treatment options:

  1. If cervical involvement is documented, options include radical hysterectomy, bilateral salpingo-oophorectomy, and pelvic and para-aortic lymph node dissection.

  2. If the cervix is clinically uninvolved but extension to the cervix is documented on postoperative pathology, radiation therapy should be considered.

The completed GOG-LAP2 trial included 2,616 patients with clinical stage I to IIA disease and randomly assigned them two-to-one to comprehensive surgical staging via laparoscopy or laparotomy.[3] Time to recurrence was the primary endpoint, with noninferiority defined as a difference in recurrence rate of less than 5.3% between the two groups at 3 years. The recurrence rate at 3 years was 10.24% for patients in the laparotomy arm, compared with 11.39% for patients in the laparoscopy arm, with an estimated difference between groups of 1.14% (90% lower bound, -1.278; 95% upper bound, 3.996). Although this difference was lower than the prespecified limit, the statistical requirements for noninferiority were not met because of a lower-than-expected number of recurrences in both groups. The OS at 5 years was 89.8% in both groups. Future analyses may determine whether there are subgroups of patients for whom there is a clinically significant decrement when laparoscopic staging is utilized.[3][Level of evidence: 1iiDiii]

Current Clinical Trials

Check for U.S. clinical trials from NCI's list of cancer clinical trials that are now accepting patients with stage II endometrial carcinoma. The list of clinical trials can be further narrowed by location, drug, intervention, and other criteria.

General information about clinical trials is also available from the NCI Web site.
