NCT ID: NCT06115577 Completed - Endometrial Cancer Clinical Trials

Endometrial Tissues and Mononuclear Cells Receptivity in Pathogenesis of Endometrial Proliferative Processes

Start date: October 1, 2012
Phase:
Study type: Observational

A prospective observational study of endometrial tissue and peripheral blood mononuclear cells receptivity to sex steroid hormones in postmenopausal patients with endometrial proliferative processes

NCT ID: NCT03437837 Completed - Breast Cancer Clinical Trials

Validation of the CPS+EG, Neo-Bioscore and Modified Neo-Bioscore Staging Systems After PST of BC in China

Start date: May 1, 2017
Phase:
Study type: Observational

Prognostic assessment after preoperative systemic therapy (PST) plays a vital role in breast cancer patients. The clinical-pathologic staging system incorporating estrogen receptor (ER)-negative disease and nuclear grade 3 tumor pathology (CPS+EG staging system) can effectively predict prognosis after PST. The Neo-Bioscore has been developed by the incorporation of the human epidermal growth factor receptor 2 (HER2) status into the CPS+EG staging system. But in a real world in China, the both staging systems had limits because of trastuzumab administration varied a lot in China from the United States. This retrospective study will validate CPS+EG and Neo-Bioscore system and explored a modified Neo-Bioscore system in multiple centers.

NCT ID: NCT00897299 Completed - Breast Cancer Clinical Trials

Identifying Genes That Predict Recurrence in Women With Breast Cancer Treated With Chemotherapy

Start date: October 7, 2005
Phase: N/A
Study type: Observational

RATIONALE: Studying samples of tumor tissue from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer. It may also help doctors predict whether cancer will come back after treatment. PURPOSE: This laboratory study is identifying genes that may help predict recurrence in women with breast cancer treated with chemotherapy.
