Article Synopsis
  • The study aims to evaluate the prognostic impact of isolated tumor cells in sentinel lymph nodes (SLNs) of low-risk endometrial cancer patients who did not receive additional therapy.
  • A total of 494 patients were analyzed, finding that recurrence rates were higher in those with SLN-isolated tumor cells, with significant differences in recurrence-free survival between this group and node-negative patients.
  • Although isolated tumor cells were associated with poorer recurrence-free outcomes, no significant differences in overall survival between the two groups were observed.

Objectives: Endometrial cancer (EC) is the most common gynecological malignancy. The fluorine-fluorodeoxyglucose (F-FDG) positron emission tomography/computed tomography (PET/CT) is used for initial staging, evaluating treatment response, and detecting recurrence. This study aimed to investigate the diagnostic value of preoperative PET/CT in EC staging and determine the volumetric PET parameters that are accurate predictors of histopathological tumor characteristics.

Article Synopsis
  • - This study evaluated how effective the sentinel lymph node (SLN) mapping method is in diagnosing high-risk endometrial cancer in 244 patients with specific tumor types and characteristics.
  • - Results showed that 91% of patients had at least one SLN detected, with high sensitivity (81.8%) and low false-negative rates (18.2%), which improved significantly with the SLN algorithm applied.
  • - The findings suggest that the SLN mapping approach is highly accurate for detecting metastases, particularly in high-grade tumors, but further long-term studies are needed before it can be widely adopted as standard care.

Presented herein is the only case in literature with the synchronous development of endometrioid-type endometrium cancer and endometrioid carcinoma originating from the endometriosis foci in a scar tissue. A 44-year-old female patient presented with complaints of abnormal uterine bleeding, swelling at the rectus muscle level in the abdominal wall, and cyclic pain close to the old cesarean section incision scar. Pathological findings of the rectus muscle and endometrial biopsies revealed endometrioid adenocarcinoma (grades 2 and 1, respectively).

Objective: This study aimed to find out whether side-specific pelvic lymphadenectomy can be omitted without compromising diagnostic efficacy according to "reflex frozen section" analysis of the uterus in case of sentinel lymph node (SLN) mapping failure.

Methods: Patients who underwent surgery for endometrial cancer with an SLN algorithm were stratified as low-risk or high-risk according to the uterine features on the final pathology reports. Two models for low-risk patients were defined to omit side-specific pelvic lymphadenectomy: strategy A included patients with endometrioid histology, grade 1-2, and <50% myometrial invasion irrespective of the tumor diameter; strategy B included all factors of strategy A with the addition of tumor diameter ≤2 cm.

Article Synopsis
  • The study aimed to assess the effectiveness of combining sentinel lymph node (SLN) mapping with PET/CT scans to identify lymph node involvement in patients with endometrioid endometrial cancer (EEC).
  • Data from 95 EEC patients who underwent SLN mapping and had preoperative PET/CT imaging were analyzed, revealing SLNs in 81.1% of cases, and only a small number showed metastasis despite negative PET/CT results.
  • Findings suggest that using both SLN mapping and PET/CT can potentially reduce unnecessary lymph node removal surgeries, as no metastases were found in the non-sentinel lymph nodes of patients with negative results from both tests.
