Background: This study examines the relationship between mismatch repair (MMR) gene expression and clinicopathological features in patients with low-grade endometrial cancer (EC). Methods: A prospective cohort of 40 patients with histologically confirmed low-grade EC underwent immunohistochemical analysis to determine MMR status. Clinical data, including age, body mass index (BMI), menopausal status, parity, and comorbidities, were collected. Histopathological evaluations assessed myometrial invasion,lymphovascular invasion and disease stage. Results: MMR deficiency (MMRd) was identified in 35% of patients, predominantly associated with MLH1/PMS2 loss. No significant associations were found between MMR status and clinical characteristics such as age, BMI, or comorbidities. However, MMRd tumors exhibited a significantly higher prevalence of myometrial invasion over 50% (85.71% vs. 38.46%, p=0.0042) and lymphovascular invasion (71.43% vs. 19.23%, p=0.00114). Additionally, MMRd cases were more frequently associated with advanced disease stages, particularly in stage IIIC (28.57% vs. 7.69%, p=0.078). Conclusion: The importance of MMR status in the biological behavior of low-grade endometrial cancer is highlighted in this study. The strong correlation between MMR deficiency and aggressive histopathological features such as increased myometrial and lymphovascular invasion, highlights the need to integrate MMR testing into clinical practice, even if clinical parameters showed no significant association with MMR expression. These results suggest that MMRd may be a useful prognostic indicator that requires more research to improve patient outcomes and treatment approaches for low-grade endometrial cancer.

Although endometrial cancer is the fourth most common malignancy among women, it rarely metastasizes to the small intestine. Cases of endometrial recurrence to the intestine clinically present with secondary anemia, melena, abdominal cramps, and epigastric pain. Only a dozen cases are reported in the literature, but none presented with an enterocutaneous fistula. In this report, we present a case of an 88-year-old female patient previously treated for endometrial adenocarcinoma with surgery and adjuvant radiotherapy. Fourteen months after the surgery, the patient presented with an enterocutaneous fistula on the anterior abdominal wall, which was confirmed to be a metastasis from the primary tumor. To our knowledge, this is the first case of endometrial cancer metastasizing to the small intestine with involvement of the anterior abdominal wall and the occurrence of an enterocutaneous fistula, which was treated with radical surgery.

Preoperative detection of sentinel lymph node in patients with endometrial cancer - comparison of planar lymphoscintigraphy, spect and SPECT/CT
(2022)

Sentinel lymph node (SLN) mapping allows minimal invasive assessment of lymph node status in patients with early-stage endometrial cancer (EC). Intraoperative detection of SLNs is based on the results obtained from preoperative nuclear medical images. The purpose of this study was to compare the data obtained from planar lymphoscintigraphy (PL), single-photon emission computed tomography (SPECT), and SPECT with computed tomography (SPECT/CT) for preoperative SLN detection in patients with EC.

BACKGROUND: Endometrial cancer is the third-ranked genital malignancy in women and includes 3% of cancer deaths. There is a 2.8% chance of a woman developing endometrial cancer during her lifetime. Low-grade endometrioid adenocarcinomas are often seen along with endometrial hyperplasia, but high-grade endometrioid adenocarcinomas have more solid sheets of less-differentiated tumour cells, which are no longer organised into glands, often associated with surrounded atrophic endometrium.CASE REPORT: We present an unusual case of endometrial adenocarcinoma arising in adenomyoma in 74-year old woman presented with genital prolapse, without other clinical symptoms. Ultrasound evaluation revealed endometrium with 4 mm-thickness and atrophic ovaries. The cervical smear was normal. The patient underwent a total vaginal hysterectomy. The histopathology of the anterior uterine wall revealed an intramural adenomyoma of 4 mm in which some endometrial glands with malignant transformation of well-differentiated endometrioid adenocarcinoma without infiltration in surrounding myometrium and lymphovascular invasion were present. The endometrium lining the uterine cavity was predominantly atrophic, and only one focus of simplex and complex hyperplasia was found, with cell-atypia. According to AJCC/FIGO 2010, the tumour was classified: pTNM = pT1B pNX pMX G1 R0 L0 V0 NG1, Stage I. On dismiss, the near-future oncological consultation was recommended.CONCLUSION: We would like to point out the rare occurrence of such type of malignancy and the importance of meticulous histopathology evaluation, even after reconstructive surgery for genital prolapse.
