Active clinical trials for "Endometrial Neoplasms"

This research study will test the efficacy of interactive, web-based interventions that improve diet, physical activity and weight management changes among early stage survivors of breast, prostate, colorectal, endometrial, renal, thyroid, and ovarian cancers, as well as multiple myeloma and non-Hodgkin Lymphoma. Overarching outcomes also include physical function and performance, muscle mass, quality of life, and health utilities.

Programmed cell death 1 (PD-1) inhibitor treatment may benefit patients with endometrial cancer (EC) based on the following observations: 1) an overwhelming presence of PD-1 in ECs; 2) the well-known effect of obesity which activates pro-inflammatory white blood cells and promotes the development of ECs; and 3) the high prevalence of a specific gene pattern (ie, microsatellite instability hypermutated [MSI high]) among ECs that may be particularly sensitive to this class of drugs. To identify potential biomarkers of response to PD-1 inhibitors in EC, we will conduct a window of opportunity study of pembrolizumab in 20 patients with clinical stage 1, grade 3 EC, encompassing endometrioid, serous and clear cell histologies. Eligible patients will undergo a research biopsy for collection of fresh tissue at the time of enrollment, in addition to the routinely performed endometrial biopsy that led to the diagnosis of their cancer. Patients will receive a single dose of pembrolizumab (200 mg IV) prior to undergoing their scheduled hysterectomy with surgical staging three weeks later. As per standard of care, adjuvant chemotherapy with paclitaxel and carboplatin will be recommended after hysterectomy/surgical staging for women with endometrioid tumors and stage III disease or women with serous/clear cell tumors at all stages of disease. However, in this study pembrolizumab will be added to adjuvant paclitaxel and carboplatin for EC. Pre-treatment endometrial biopsy specimens (fresh frozen tissue and formalin-fixed paraffin embedded (FFPE)) and a post-treatment hysterectomy specimen (fresh frozen tissue and FFPE) will be collected for translational studies. Blood, fecal and vaginal samples will be collected pre-treatment, at the time of surgery and following 3 cycles of adjuvant pembrolizumab/paclitaxel/carboplatin treatment.

Advanced technology has enabled radiation oncologists to more accurately and precisely target radiation to areas at risk while maximally sparing healthy tissue. A secondary result of these technologic advances has been the increased utilization of hypofractionationed treatment protocols, since the combined ability to better visualize and precisely deliver radiation to target volumes has allowed radiation oncologists to leverage the therapeutic ratio toward higher target doses whilst maintaining safe doses to the pertinent organs-at-risk. The spectrum of hypofractionation ranges from what are considered moderate (ie. 2- 5 Gy / fraction) into the realm of what is more commonly referred to as stereotactic body (SBRT), generally >5 Gy / fraction. There is growing evidence demonstrating both safety and efficacy for SBRT. The investigators propose that these advantages are translatable to the adjuvant treatment of endometrial cancer. The investigators submit that a prescription dose of 30 Gy in 5 fractions. Through precision delivery and careful dosimetry the treatment should be safe and well tolerated with minimal impact on patient quality of life.

Evaluation of removal of Sentinel lymph nodes only for detection of pelvic lymph node metastases in high risk and low risk endometrial cancer.

The objective of the present study is to implement and evaluate the effect of a counseling program to promote healthy eating and practice of physical activity in the nutritional status, quality of life and prognosis of women Type I (endometrioid) endometrial cancer.

Up to 60% of endometrial cancer cases are attributed to obesity, in part because obesity promotes development of atypical endometrial hyperplasia (AEH), and up to 40% of women with AEH go on to develop endometrial cancer. The increasing prevalence of obesity in premenopausal women has resulted in increasing rates of AEH in this age group. Hysterectomy with removal of the fallopian tubes and ovaries is 100% effective in preventing endometrial cancer, but this approach results in infertility. Fertility-sparing treatments exist, such as treatment with oral or intrauterine progestin, but these treatments do not work uniformly and do not combat the underlying cause of endometrial cancer, which is obesity and metabolic syndrome. Additionally, up to 41% of women on progestin eventually experience relapse of AEH or endometrial cancer. Third, many patients have insulin resistance that may worsen with progestin therapy. Thus, to improve treatment of AEH and grade 1 endometrial cancer, prevent and reverse endometrial cancer, and allow women to preserve their fertility, the investigators must integrate an effective weight loss strategy to be given with progestin treatment. It is the hypothesis that premenopausal women with endometrial hyperplasia or grade 1 endometrial cancer who desire uterine preservation will be more likely to have atypia-free uterine preservation at two years if they receive progestin in combination with a behavioral weight loss intervention versus progestin plus enhanced usual care.

This a phase II and III study whose purpose is to compare how long various treatment regimens can keep the cancer from worsening or coming back in people with serous or p53 abnormal endometrial cancer. The study is divided into three cohorts: Early stage cohort, advanced stage cohort, and exploratory cohort. Each cohort will have different arms to examine different treatment regimens to determine the best regimen for each cohort. The study will enroll participants into the early stage cohort at this time. The early stage cohort will compare the following treatments after standard of care surgery: Adjuvant chemotherapy with carboplatin and paclitaxel alone Adjuvant radiation therapy and chemotherapy with cisplatin, followed by chemotherapy with carboplatin and paclitaxel.

ONC201 is a small molecule which selectively targets the G protein-coupled receptor DRD2. Downstream of target engagement, ONC201 activates the integrated stress response (ISR) in tumor cell leading to inactivation of Akt and extracellular signal-regulated kinase (ERK) signaling as well as induction of the TRAIL pathway. ONC201 also inhibits dopamine receptor 2 (DRD2), resulting in anti-tumor responses in preclinical models. Single agent ONC201 has been examined in open-label Phase I studies in patients with advanced, treatment refractory solid malignancies. Due to its differential anti-proliferative and pro-apoptotic response in tumor cells, treatment was overall well tolerated, and the recommended phase II dose of ONC201 was set at 625mg every three weeks. An additional dose-escalation phase I study (NCT02609230) is further evaluating weekly versus three week dosing in patients with advanced solid tumors and multiple myeloma. Preliminary data from these phase I studies suggests a possible clinical benefit in patients with advanced, chemo-refractory endometrial cancers, with at least one mixed response noted in a patient with clear cell histology. Hypothesis: Single agent ONC201 will demonstrate clinical benefit in women with recurrent or metastatic endometrial cancers, especially in those women with alterations in the Phosphoinositide 3 kinase (PI3K)/Akt/mammalian target of Rapamycin (mTOR) pathway.

Endometrial cancer is not a single entity but rather a very heterogeneous group of diseases. Historically, endometrial cancer patients have been classified as endometrioid (type I) or non-endometrioid (type II) according to the dualistic Bokhman model- However, this approach has been limited in accurately predicting prognosis and guiding treatment owing to heterogeneity within subtypes, inadequate incorporation of molecular and genetic information, and high interobserver variability . In the last ten years, after the publication of The Cancer Genome Atlas (TCGA)[5], the molecular classification of endometrial cancer into four molecular subtypes [(i) POLE/ultramutated group (POLE mutated), (ii) mismatch repair deficiency/microsatellite-instable, hypermutated group (MMRd/MSI-H), (iii) copy-number-high, TP53-mutant (CNH/p53abn), and (iv) copy-number-low, TP53-wild-type (CNL, or No Specific Mutational Profile [NSMP])] has rapidly gained interest. Recently, the European Societies of Gynaecological Oncology, Radiotherapy and Oncology, and Pathology (ESGO-ESTRO-ESP), the European Society of Medical Oncology (ESMO), the National Comprehensive Cancer Network (NCCN), and the new 2023 International Federation of Gynecology and Obstetrics (FIGO) staging system have promoted the use of (surrogate) molecular classification. Retrospective studies supported the value of adopting molecular classification to offer reliable data on prognostication and adjuvant treatment decisions. Although no prospective data are available, current guidelines promote the use of molecular profiles to tailor adjuvant treatment after surgery. As only a few retrospective studies have investigated the association between molecular profiles and response to various adjuvant treatments, it is important to note that data are limited. Interestingly, the growing adoption of molecular profiling led to the detection of a subgroup of tumors called multiple classifiers, characterized by multiple (two or three) molecular features. According to the guidelines, tumors with a POLE mutation should be considered POLEmut, regardless of other molecular features, whereas MMRd/MSI-H tumors with a p53 abnormality should be considered MMRd/MSI-H. Data on these patients is limited and fragmentary. The aforementioned consensus is based solely on a large retrospective cohort of multiple classifiers collected by Leon-Castillo et al.. Hence, to fill this literature gap, the investigators designed this retrospective study, which aimed to collect multiple classifiers patients to improve knowledge on this emerging category.

Based on the previous study of NCT04651738, we performed this trial to further confirm the accuracy of host DNA CDO1 and CELF4 methylation for endometrial cancer screening. This study would provide profound basis for the approval of assay kit of DNA methylation in China for endometrial screening. Four hospitals, including Peking Union Medical College Hospital, would enroll eligible patients in this study. The cervical cytology of 3 ml will be collected for the detection of DNA CDO1 and CELF4 methylation, and the results will compared with the endometrial histological pathology, which is achieved after collection of cervical cytology, by surgeries including hysteroscopy, dilation and curettage, total hysterectomy and others. The methylation testing would be double-blinded in operators and analysts. The study will enroll at least 7150 patients.
