We have developed the 16F12 mouse monoclonal antibody (mAb) that targets the MISRII receptor expressed by ovarian tumors. Here, we assessed in preclinical models the possibility to use radiolabeled 16F12 in a theranostic approach for small-volume ovarian peritoneal carcinomatosis, for instance after cytoreductive surgery. Methods: DOTA-, DTPA- or DFO-conjugated 16F12 mAb was radiolabeled with beta (177 Lu) or alpha (213 Bi) particle emitters for therapeutic use, and with 89 Zr for positron emission tomography (PET) imaging...

INTRO: Dedifferentiated/undifferentiated endometrial carcinomas (DDEC/UEC) are aggressive endometrial cancers with frequent genomic inactivation of core components of switch/sucrose non-fermentable (SWI/SNF) complex proteins. Claudin-4, an epithelial intercellular tight junction protein was recently found to be expressed in SWI/SNF-deficient undifferentiated carcinomas but not SWI/SNF-deficient sarcomas. The aim of this study is to examine claudin-4 expression in UEC/DDEC and other high-grade uterine carcinomas...

Cervical leiomyosarcoma is known to be rare from the previous reviews of a large number of malignant cervical tumors. The patient was a 66-year-old woman with irregular vaginal bleeding. She underwent modified radical hysterectomy and bilateral salpingooophorectomy. Histopathologically, we diagnosed the coexistence of uterine cervical leiomyosarcoma and cervical gastric-type adenocarcinoma in situ with endometrial lesions that had continuous and skip patterns and fallopian tubal lesions with a partial lesion...

Background Better selection of patients with intermediate and high-risk stage I endometrial carcinoma (EC) for lymphadenectomy has an important effect on the prognosis. Purpose To investigate the role of apparent diffusion coefficient (ADC) measurements in the assessment of stage I EC patients based on three risk categories. Material and Methods We retrospectively studied 80 patients with EC and 28 cervical cancer patients with normal endometrium. 1.5-T conventional magnetic resonance imaging (MRI) and diffusion-weighted imaging (DWI) (b = 0, 1000 s/mm2 ) were performed, and ADC values were calculated...

We performed RNA-seq on an Illumina platform for 7 patients with endometrioid endometrial carcinoma for which both tumor tissue and adjacent noncancer tissue were available. A total of 66 genes were differentially expressed with significance level at adjusted p value < 0.01. Using the gene functional classification tool in the NIH DAVID bioinformatics resource, 5 genes were found to be the only enriched group out of that list of genes. The gene IGSF9 was chosen for further characterization with immunohistochemical staining of a larger cohort of human endometrioid carcinoma tissues...

Endometrial carcinoma (EC) is the most common malignant gynecologic tumor in women. EC is thought to be caused by increasing estrogen levels relative to progesterone in the body. Hesperidin (Hsd), a biologically active flavonoid, could be extracted from Citrus species. It has been recently shown that Hsd could exert anticarcinogenic properties in different cancer types. However, the effects of Hsd and its molecular mechanisms on EC remain unclear. In this study, the antiproliferative, apoptotic and genomic effects of Hsd in EC and its underlying mechanisms were identified...

Endometrial carcinoma (EC) is the most common malignant tumor of the female genital tract in developed countries. The prognosis of early stage EC is favorable, but a subset faces high risk of cancer progression or recurrence. EC has a poor prognosis upon progression to advanced or metastatic stages. Therefore, our goal is to build a robust prognostic model for predicting overall survival (OS) in EC patients. In this study, 1571 genes were identified as being associated with OS based on genomewide expression profiles using a training dataset...

A 53-year-old woman was diagnosed with endometrial carcinoma by vaginal bleeding. F-18 fluorodeoxy glucose positron emission tomography PET/CT (F-18 FDG PET/CT) scan for staging showed intense focal FDG uptake in the endometrium suggesting endometrial malignancy. PET/CT showed multiple node uptakes in the pericaval region, paraaortic region, common iliac, and both internal iliac and external iliac regions suggesting multiple pelvic and retroperitoneal node metastases. MRI showed multiple metastatic lymphadenopathy in the retroperitoneum and pelvic cavity...

INTRODUCTION: The cornerstone of treatment for endometrial carcinoma is total abdominal hysterectomy and bilateral salpingo-oophoprectomy. Pelvic lymphadenectomy, with or without para-aortic lymphadenectomy, plays an important role in the surgical staging of endometrial carcinoma, and provides more accurate prognostic information. AIMS: We aimed to evaluate the value and techniques for SLN mapping in early stage endometrial cancer with low risk for lymph node metastasis and whether selective or systematic lymphadenectomy is needed according to the results of proposed algorithm...

Hereditary breast and ovarian cancer syndrome (HBOC) is most frequently caused by mutations in BRCA1 or BRCA2 (in short, BRCA) genes. The incidence of hereditary breast and ovarian cancer in relatives of BRCA mutation carriers who test negative for the familial mutation (non-carriers) may be increased. However, the data is controversial, and at this time, these individuals are recommended the same cancer surveillance as general population. One possible explanation for BRCA phenocopies (close relatives of BRCA carriers who have developed cancer consistent with HBOC but tested negative for a familial mutation) is natural chimerism where lack of detectable mutation in blood may not rule out the presence of the mutation in the other tissues...

ARID1A is a tumour suppressor gene that is frequently mutated in clear cell and endometrioid carcinomas of the ovary and endometrium and is an important clinical biomarker for novel treatment approaches for patients with ARID1A defects. However, the accuracy of ARID1A immunohistochemistry (IHC) as a surrogate for mutation status has not fully been established for patient stratification in clinical trials. Here we tested whether ARID1A immunohistochemistry could reliably predict ARID1A mutations identified by next-generation sequencing...

OBJECTIVE: Universal screening of endometrial cancer (EC) for Lynch syndrome (LS) has been increasingly implemented in the past five to ten years. Most pathologists initiate screening with immunohistochemistry (IHC) for mismatch repair proteins (MMRPs), using either pre-surgical samplings (endometrial biopsy or curettage, EMB/C) or hysterectomy specimens. We report a systematic assessment of the equivalence of IHC for LS screening on EMB/C versus hysterectomy specimens. METHODS: We identified 99 patients diagnosed with endometrioid EC and performed IHC for MMRPs MLH1, MSH2, MSH6, and PMS2 on their diagnostic EMB/C and paired hysterectomy specimen...

OBJECTIVE: Positive peritoneal cytology (PPC) in endometrial cancer remains a controversial topic. Cleaved caspase-3 (CC3) and Ki-67 are excellent markers of apoptotic and proliferating cells, respectively. The objective of this study was to determine the significance of CC3 and Ki-67 expression in peritoneal cytology samples as prognostic factors for endometrial cancer with PPC. METHODS: Sixty endometrial cancer specimens with PPC alone were divided into 51 endometrioid tumours (43 endometrioid carcinomas and 8 carcinomas with squamous differentiation) and 9 non-endometrioid tumours (2 serous carcinomas, 3 clear cell carcinomas, and 4 carcinosarcomas)...
