Filter by:The purpose of this study is to develop a liquid biopsy approach for detection of circulating tumor cells (CTC) that could be used in place of the more invasive and potentially risky methods of tissue biopsy. The aims of the project are: (a) determine whether the Chaperonin-Containing TCP-1 (CCT) chaperonin can used to identify rare cancer cells in blood, and (b) establish whether the cancer cells detected using the CCT chaperonin for identification have invasive or metastatic potential.
To investigate the effects of perioperative anesthetic drugs propofol and desflurane on circulating tumor nucleic acids (CK7, ELF3, EGFR and EphB4 mRNA) in the blood of patients with liver cancer, so as to provide scientific reference for clinical anesthesia in the perioperative treatment of tumor
Among biomarkers, CTCs are a convenient, sensitive and biologically informative option. CTC detection could be considered a real-time "liquid biopsy" approach and contains several advantages such as minimally invasive, easy and safe to perform, and multiple samples can be taken over time, better prognosis to indicate an elevated risk of metastases, improved therapy monitoring, providing live disease status information., However, the number of CTCs is very low, so the establishment of cell culture from CTCs becomes the most challenging over the past year. In this study, we develop a short-term CTC expansion protocol combined with a new surface coating technique. Expanded circulating tumor cells will provide genetic information and develop oncology drug screening platform, which provides an opportunity to monitor response to therapy noninvasively.
Circulating tumor cells (CTCs) in peripheral blood originate from breast cancer (primary and metastatic lesions) shedding. Utilization of CTCs as novel and noninvasive tests for diagnosis confirmation, therapy selection, and cancer surveillance is a rapidly growing area of interest. In this project, the investigators will explore a novel detection technology of circulating tumor cells in breast cancer using novel Microfluidic and Raman Spectrum Device. The primary objective is to demonstrate that the CTC assay counts technology can distinguish between healthy subjects and malignant breast cancer subjects. The secondary objective is to demonstrate that the CTCs detection technology can evaluate the efficacy of chemotherapy and neoadjuvant chemotherapy, as well as dynamic treatment monitoring and prognosis evaluation.
Verify the Coincidence rate between Circulating tumor cells (CTCs) and tumor tissue or Circulating tumor DNA (ctDNA) of advanced NSCLC patients with Driver gene mutation
Identification of biomarkers (Circulating Tumor Cells (CTC), free DNA, Stem Cells and EMT-related antigens) that may be predictive of outcome of activity of cabazitaxel treatment in castration-resistant prostate cancer.
This multicentre, prospective and randomized study aims(1:1) to compare the rate of recurrence, metastasis and survival according to the levels of intraoperative circulating tumor cells (CTCs) during cephalic duodenopancreatectomy in patients with pancreatic and periampullary tumors.
Evaluating the application value of a new circulating tumor cell detection method for advanced gastric cancer patients in prediction of the prognosis and early evaluation of the result of postoperation adjuvant chemotherapy.
This study compares the biological activity of cabazitaxel (6 cycles) to that of docetaxel (6 cycles) in metastatic castrate-resistant prostate cancer (mCRPC) patients with docetaxel resistant mCRPC defined as ≥5 circulating tumor cells (CTCs) / 7.5 mL after 2 cycles of docetaxel. Patients with docetaxel resistant metastatic castration-resistant prostate cancer (mCRPC) based on circulating tumor cell (CTC) enumeration (patients with ≥5 CTCs / 7.5 mL before docetaxel chemotherapy and after 2 cycles of docetaxel) will receive either 6 additional cycles of docetaxel or 6 additional cycles of cabazitaxel after randomisation. A cohort of patients with docetaxel sensitive metastatic castration-resistant prostate cancer (mCRPC) based on circulating tumor cell (CTC) enumeration (patients ≥5 CTCs / 7.5 mL before docetaxel chemotherapy and <5 CTCs / 7.5 mL after 2 cycles of docetaxel) will receive 6 additional cycles of docetaxel.
The primary purpose of this study is to compare both short-term and long-term treatment effect of laparoscopic vs. open approach on progressive gastric and rectal cancer, based on circulating tumor cell (CTC) test results as well as disease-free survivals, and figure out principles of laparoscopic approach for progressive gastric and rectal cancer. Secondary purpose is to establish an evaluation system for laparoscopic surgery for progressive gastric and rectal cancer treatment using CTC as a biomarker.
