Prognostic Role of Kr üppel-Like Factors 5, 9, and 11 in Endometrial Endometrioid Cancer.

Prognostic Role of Krüppel-Like Factors 5, 9, and 11 in Endometrial Endometrioid Cancer. Pathol Oncol Res. 2020 May 25;: Authors: Viola L, Londero AP, Bertozzi S, Orsaria M, Marzinotto S, Antoniazzi F, Renda V, Cinel J, Fruscalzo A, Lellé RJ, Mariuzzi L Abstract BACKGROUND AND OBJECTIVE: Krüppel-like factors (KLFs) are transcription factors with the ability to mediate cross-talk with signaling pathways involved in cell proliferation control, apoptosis, migration, and differentiation. They also appear to influence steroid hormone signaling through transcriptional networks involving steroid hormone receptors and members of the nuclear receptor family of transcription factors. Our study aims to evaluate the potential prognostic role of KLF5, KLF9, and KLF11 in endometrial cancer, and their correlation with hormonal receptor status and cellular proliferation. MATERIALS AND METHODS: Retrospective observational study on cases of endometrioid endometrial adenocarcinoma collected in the period January 2000-December 2011 at the University of Udine. Formalin-fixed, paraffin-embedded tissue samples were all submitted to tissue microarray immunohistochemical study. A survival analysis was performed. RESULTS: One hundred forty seven patients were included in the study with a mean age at surgery of 65.6 years (±10.2). 80.3% of endometrial malignancies were classified as stage FIGO I (118/147). Radiation therapy and chemotherapy w...

CONCLUSIONS: This study demonstrated the over-expression of the druggable target Parp-1 in endometrial adenocarcinoma and observed a strong negative correlation of native Parp-2 expression and disease progression via the quantification of the Parp proteins using enzyme- linked immuno-sorbent assay (ELISA) assays.

We present a 47-year-old woman with an MLH1 gene mutation (G133X 397G>T) who presented with menorrhagia. Eleven family members have this mutation, 6 with carcinoma: 5 colorectal and 1 with a gynecologic primary of unknown type. Colonoscopy and endoscopy were unremarkable. Positron emission and computed tomography revealed a 3 cm anterior dome bladder mass without additional extrauterine disease or uterine connection. She underwent partial cystectomy, laparoscopic hysterectomy, bilateral salpingo-oophorectomy, and lymphadenectomy. The uterus demonstrated a dedifferentiated endometrioid adenocarcinoma, immunohistochemical...

This report is the first to link components of a unique β-catenin+ endometrioid carcinogenic sequence in the fallopian tube. It further emphasizes the multifocal nature of endometrioid neoplasia in the female genital tract and poses questions regarding the frequency and biologic underpinnings of β-catenin+ proliferations in the oviduct.

We describe the case of a stage IA grade 1 endometrioid endometrial adenocarcinoma diagnosed at the time of missed abortion in a gravida 1 para 0 female with no identifiable risk factors. Fertility-sparing treatment, with combined oral megestrol acetate and levonorgestrel intrauterine system, was used to manage this incidentally-found carcinoma with endometrial sampling every 3 months.

Abstract OBJECTIVES: Enhancer of zeste homolog 2 (EZH2) is a histone methyl transferase that mediates epigenetic silencing of tumor suppressor genes. It is commonly over-expressed in several solid tumors and has been shown to be a prognostic biomarker. We investigated patterns of EZH2 expression in endometrial cancer. METHODS: Evaluation of EZH2 expression was completed on both early and advanced stage endometrioid adenocarcinoma tissues and a subset of matched normal mullerian tissue samples, from participants enrolled in Gynecologic Oncology Group (GOG) protocol 210, using real time reverse transcription po...

CONCLUSION: Adjuvant chemotherapy was associated with an overall survival benefit for patients with inadequately-staged, grade 2 stage I ovarian endometrioid adenocarcinoma. A possible benefit for inadequately-staged patients with grade 3 tumors cannot be excluded. PMID: 31839340 [PubMed - as supplied by publisher]

ConclusionsPositive findings in abdominopelvic washing cytology is rare. The majority of the positive cases were from müllerian origins, with ovary and uterus as the most common sites. Endometrial adenocarcinoma, endometrioid type and ovarian high-grade serous carcinoma were the most common tumor types. Knowing prior history of malignancy, morphologic comparison with concurrent surgical cases, and performing ancillary studies are keys to improve diagnostic accuracy of abdominopelvic washings.

ConclusionEndometrial cancer, specifically type I endometrioid adenocarcinoma and its precursor lesions are strongly associated with unopposed estrogen states such as polycystic ovarian syndrome (PCOS), obesity as well as nulliparity. Patients seeking assisted reproductive technologies make up a subset of these patients and strongly desire to maintain their fertility. Progesterone therapy for select patients may be a safe and effective temporary treatment for endometrial carcinoma and atypical precursor lesions prior to starting IVF-ET. IVF-ET is very effective in treating such patients.
