Active clinical trials for "Endometrial Neoplasms"

We wish to study radiation therapy in uterine cancer, focusing on dosimetry analysis, clinical implication, and survival analysis.

Investigators aim to collect endometrial sampling with Li Brush among target population who have risks for endometrial neoplasm, then Fractional curettage should performed with these participants, investigators intend to compare the pathological diagnosis results of cytology and fractional curettage to evaluate the sensitivity of Li Brush and investigators expect that the brush can be used for screening of endometrial cancer in the postmenopausal period in the clinic.

Endometrial cancer is one of the most common gynecological cancers, and the incidence increasing in the world. However, there isn't any large sample data of endometrial cancer reported in China. Thus Endometrial cancer project of Guangdong province conduct a large multicentre clinical investigation about endometrial cancer.

In patients diagnosed as endometrial cancer by thorough pathologic examinations, Lynch syndromes are screened by (1)immunohistochemical staining (for MLH1, MSH2, MSH6 and PMS2), (2) tests of microsatellite instability and (3) clinical criteria (Amsterdam I or II criteria and Bethesda criteria). For patients with any suspicious discoveries of Lynch syndromes from aforementioned screening methods, a molecular diagnosis with next-generation sequencing for mismatch repair genes (MLH1, MSH2, MSH6, PMS2, and EPCAM) is given to confirm Lynch syndromes. For patients of Lynch syndromes and endometrial cancer, relatives of blood lineage are tested by Sanger method or qPCR to find out carriers of mutation genes of Lynch syndromes.

Endometrial carcinoma is the most common gynecologic cancer in the western world. Two types are usually described. Type I is the endometrioid and is usually estrogen dependent. Type II is usually more aggressive than type I and is estrogen independent. Type II endometrial cancer is usually characterized as high grade while type I as low intermediate and high grade. Ovarian carcinoma as opposed to endometrial carcinoma is not characterized by types but by different histological backgrounds. It is also divided into high and low grade tumors. Ovarian carcinoma is considered to be the most aggressive of all gynecological malignancies resulting in most yearly deaths. Our immune system usually responds to foreign intruders entering our body or formed inside and attacks it in order to destroy it. Cancer cells are considered to be foreign to the body hence the immune system is expected to destroy it . The immune mediated cells which are supposed to attack the cancer are called tumor infiltrating lymphocytes or "TILS". Many different cancers possess the ability to evade TILS in order to survive and grow. Many studies have demonstrated that the presence of large number of TILS improved cancer prognosis. One of these evasive methods is the PD-1/PDL-1 expression. The question whether more aggressive tumors possess better capabilities to evade an immune response via the PD-1/PDL-1 mechanism is currently unknown. All tumor types possess antigens on their cell surface which triggers an immune response to some extent. Even though, the tumor needs different methods in order to be able to avoid the immune system attack. TILS express the PD-1 receptor on their cell surface and when it binds to PDL-1 or PDL-2, the cells which express the ligand deactivate TILS hence deem the lymphocyte incapable of inducing programmed cell death. PDL-1 which is expressed on tumor cells to evade an immune response can be targeted by immunotherapy.

This study aims to explore the sensitivity of an innovative marker, HE4, in the diagnosis approach of endometrial cancer in case of postmenopausal bleedings.

Objective: To examine the risk factors for coexisting endometrial carcinoma in patients with endometrial hyperplasia. Method: Seventy-seven patients who received hysterectomy for endometrial hyperplasia were enrolled and divided into the non-endometrial carcinoma group (57) and the endometrial carcinoma group (20) depending on the final pathology. Clinical variables were analyzed.

The goal of this study is to understand factors which may influence risk for colorectal and other cancers in families. These factors include genetic variability, in combination with diet and lifestyle. In order to achieve these goals, we need to contact as many eligible participants as possible.

In order to best meet the needs of all those affected by the genetic risk of cancer in our region, it is important to identify the factors likely to influence the course leading to the GENEPY surveillance network. The aim of this study is to evaluatie the adhesion to the network of care of people at genetic risk of cancer in Midi-Pyrénées (GENEPY).

The GLESS registry is a prospective multi-center observational registry. Data from the time of patient admission, operation, discharge, and follow-up will be collected for this registry. Eight gynecological conditions included were: cervical cancer, endometrial cancer, endometrial lesion, adnexal lesion, ectopic pregnancy, infertility, pelvic obstructive disorder, and genital tract deformity.
