Endometrial Adenocarcinoma

At the same time POLE-mutated endometrial carcinomas recur rarely and exhibit the excellent prognosis. Here we report the rare case of 65 y.o. female patient with endometrioid carcinoma sharing immunohistochemical and molecular features of TP53-aberrant, MMR deficient and POLE-mutated subtypes.

LLGL2 may be involved in the development of endometrial cancer as an oncogene, leading to aberrant activation of the Hedgehog signaling pathway. Therefore, LLGL2 is a potential new target for the treatment of endometrial cancer.

Metformin combined with MA may provide an effective option for fertility-sparing treatment of AEH and grade 1 stage IA EAC, and the clinical benefits of metformin for controlling MA-induced weight gain and promoting endometrial expressions of IGFBP-rP1 and p-AMPK while inhibiting p-Akt expression warrants further study.

Of the six cases of endometrial adenocarcinoma with follow-up available, four received a post-surgical treatment with meloxicam and two were treated by surgery alone...Our findings suggest the possible use of COX-2 inhibitors in treating uterine adenocarcinoma in rabbits. Further study will be needed to confirm this hypothesis.

Angoline, a JAK/STAT3 pathway inhibitor, attenuated the effect of PKM2 overexpression on the efficacy of YJP. In conclusion, YJP can inhibit the activation of the JAK/STAT3 pathway by regulating PKM2, thereby inhibiting the malignant biological behavior of HeLa cells.

While TRPS1 remains a highly sensible immunohistochemical marker for confirming breast primary lesions, pathologists should be aware of its low specificity and incorporate complementary diagnostic methods in order to ensure accurate clinical management. Further research should focus on elucidating the molecular pathways regulating TRPS1 expression in various tumor types, which may better define its clinical utility.

The simplified two-antibody MMR IHC screening approach using PMS2 and MSH6 showed high concordance with the traditional four-antibody panel. This suggests its potential as an alternative method for reflex MMR status testing in endometrial adenocarcinoma. The implementation of this approach could streamline the diagnostic process, reduce costs, and improve the detection of Lynch syndrome in affected individuals and their families. Further studies with larger cohorts and long-term follow-up are needed to validate these findings and assess the clinical implications of this approach in routine practice.

Identifying actionable mutations in this high unmet need population is crucial to improving outcomes among Black patients with uterine malignancy. Development of new targeted-therapies will need to keep these alterations at the forefront as trials are being designed.

BCL-2 expression is observed with a relatively similar frequency in DPE and SEH samples, and it is probably under the control of oestrogen hormone as the main factor involved in the pathogenesis of these lesions.

This study demonstrates, for the first time, that VM, CD146, and CD105-positive vessels are involved in EA prognosis, suggesting their potential as independent prognostic indicators and targets for antiangiogenic therapy. However, these findings require further validation through large-scale studies.

Recent research highlights that D5 exposure disrupts follicle growth, endometrial receptivity, and steroidogenesis, resulting in infertility and hormonal imbalances, potentially causing disorders like endometriosis and increased cancer risk. Chronic exposure to D5 has been linked to the development of uterine endometrial adenocarcinoma, with higher doses further elevating this risk.

In addition to its mRNA modulation function, Regnase1 is known to have deubiquitinase activity for TRAF2, 3, and 6, attenuating JNK and NFκB activity, and TFL captures and transports naked nonvesicular extracellular mRNA of IL-1β to the nucleus, enhancing the tumor-killing activity in NK cells. Based on its potential to modulate inflammation, TFL could be a future treatment target for autoimmune diseases and cancer.

Human papillomavirus and microsatellite instability tests were negative. Finally, the patient was diagnosed with stage III endometrioid adenocarcinoma of the uterine cervix and achieved complete remission after concurrent chemoradiotherapy, followed by platinum-based systemic chemotherapy.

REST was highly expressed in EC cell lines, but decreasing REST gene expression increased proliferation (FC: 1.13X, p < 0.0001), migration (1.72X, p < 0.0001), and invasion (FC: 7.77X, p < 0.05) in Ishikawa cells, which are hallmarks of cancer progression and metastasis. These findings elicit a potential role for REST as a putative tumor suppressor in EC.

Our results suggest that a combination of SOX17 and PAX8 IHCs would aid in diagnosing MLA if the results show strong positive PAX8, but negative SOX17.

This comprehensive evaluation found a molecularly diverse cohort of tumors, despite the same histology, stage and grade. Mutational signature SBS5 correlated with a high risk of recurrence. Further refining of endometrial cancer classification may enable more precise patient stratification and personalized treatment approaches.

EC molecular classification is more accurate than histotype or grade in preoperative biopsy to predict advanced disease, and together with imaging tests are the most reliable preoperative information. This work provides an initial framework for using molecular information preoperatively to tailor surgical treatment.

When the ABCA1 expressions of the grade groups and control groups were compared separately, a difference was found between Grade 1, Grade 2 and Grade 3 and the control group (p= 0.0001). According to the findings of our study, a key component in the growth of EC tumors is the increase in cholesterol production caused by a reduction in ABCA1.

While unmethylation appears to be associated with a higher relapse rate, the survival rate does not seem to be influenced by methylation. Quantitative percentages suggest that elevated MLH1 methylation is linked to relapse and mortality, though a study with a larger sample size would be essential for statistically significant results.

Based on these findings, we found a significant irregular expression of miRNA-21 in DEACs. As in other cancers, angiogenesis is significantly associated with survival in DEACs. This study provides initial data for revealing possible implications of miRNAs as prognostic indicators in DEAC.

The sensitivity and specificity of PRAME in distinguishing between endometrial and cervical adenocarcinoma in the cohort were 89.7% and 96.8%, while those in differentiating non-clear cell carcinoma of the uterus from that of the cervix reached up to 91% and 100%, respectively. Immunohistochemical staining for PRAME demonstrates statistically significant differences between endometrial and cervical carcinomas, making it a useful auxiliary diagnostic marker for differentiating cervical and endometrial adenocarcinoma, especially non-clear cell carcinoma.

We report a family of French Canadian ancestry with a germline mutation in RAD51D and two sisters presenting with endometrial carcinoma, endometrioid-type. The risk factors for endometrial adenocarcinoma, endometrioid-type are discussed in the context of the RAD51-associated carcinomas described to date.
