Special Issue Information

Dear Colleagues,

Over the last 15 years, a substantial improvement has been observed in terms of precise diagnostics of endometrial cancer, leading to changes in clinical management. The major shift was invoked by the results of the Cancer Genome Atlas (TCGA) published. Apart from classical histopathological characteristics, the data from TCGA, followed by an evaluation of clinical performance, led to defining four subgroups of endometrial cancer (POLEmut, MSI-H, copy number high with frequent P53 mutations, and copy number low). Research work, both in a translational setting and in a clinical environment, ended up with knowledge about clinical behavior and response to adjuvant treatment within each subgroup. At last, the new 2023 FIGO staging of endometrial cancer incorporates biomarkers (p53, POLE mut, and MSI-H) for staging purposes as they better predict the outcome of the disease. Further, several biomarkers explored in endometrial cancer possess an important role in the treatment of metastatic/advanced stages. These are important targets for novel therapeutic approaches (checkpoint inhibitors with or without multi-kinase inhibitors, inhibition of cytotoxic T-lymphocyte antigen-4, PARP inhibition, inhibition of human epidermal growth factor-2 therapy, inhibition of PI3K/Akt/mTOR pathways, inhibition of cyclin-dependent kinase 4/6, etc.). It is expected in the near future that translational medicine with clinical trials on the way will enable big steps for the improvement of oncologic outcomes in patients with endometrial cancer, with the avoidance of overtreatment and undertreatment. However, as precision medicine advances and is associated with higher financial costs of clinical management, we should explore possible solutions for avoiding huge disparities in patients’ access to all treatment modalities and to clinical trials.

This Special Issue aims to present a review of expected developments in biomarkers, clinical management of endometrial cancer patients, access to novel treatment, and the published results of new studies. Reviews would be focused on specific populations (e.g., the elderly, a fertility-sparing setting, and non-endometrioid cancer) and translational research (overview, what is expected in the near future), as well as in targeted therapies. Reviews would also include disparities in access to clinical trials and novel therapies.

We invite you and your colleagues to submit your articles reporting on this topic. Review articles and original research articles are all welcome.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Medicina is an international peer-reviewed open access monthly journal published by MDPI.

Background and Objectives: The aim of this study is to assess the mismatch repair (MMR) status and immunohistochemical changes in cases of recurrent endometrial cancer following primary surgery and to evaluate the impact of these changes on prognosis. Materials and Methods: Thirty-one patients diagnosed with endometrial cancer who underwent surgery and had pathologically confirmed recurrences were evaluated. Changes in MMR protein expression, estrogen receptor (ER)/progesterone receptor (PR), and p53 expression in primary surgery and recurrent tumor tissues were assessed using immunohistochemical methods. Prognostic factors influencing these parameters and survival data were investigated. Results: In the assessment of recurrent materials, there were four cases where the MLH-1&PMS-2 staining status changed from intact to loss and four cases that changed from loss to intact. No changes were observed in regard to MSH-2 &MSH-6 staining. The ratios of pMMR and dMMR following the primary surgery were 55% (n = 17) and 45% (n = 14), respectively. Four cases transitioned from pMMR to dMMR, and four cases transitioned from dMMR to pMMR. After recurrence, changes in the ER, PR, and P53 status were observed in seven, three, and three patients, respectively. Conclusions: Changes in the MMR status, receptors, and P53 were observed. It is necessary to re-evaluate prognostic parameters via biopsies in recurring cases and to adjust rescue treatments accordingly. Full article
