Gastric cancer and colorectal cancer are common gastrointestinal malignancies in the world.Early cancer generally has no obvious symptoms. Endoscopy is the "gold standard"for the diagnosis of gastric cancer and colorectal cancer.gastric cancer and colorectal cancer treatment mainly includes surgery and medication.Compared with traditional diagnosis and treatment methods, the application of gene detection technology, especially high-throughput sequencing technology (NGS) in tumor diagnosis and treatment, performs multi-dimensional and multi-target detection of cancer-related genes, which can quickly and accurately determine the target gene mutations Morphology and expression differences, so as to provide personalized guidance to patients in terms of medication, treatment or prognosis evaluation, which can save a lot of time and treatment costs, and improve the overall treatment effect and patient quality of life. Cystoscopy and biopsy sampling pathological testing are the gold standard for bladder cancer diagnosis, and have been widely used in clinical diagnosis and prognosis judgment. However, cystoscopy is cumbersome, expensive, and often causes pain to the patients under test. At present, the main clinical non-invasive detection technique for bladder cancer is still the cytological examination of urinary tract bladder cells in urine, and its sensitivity and specificity are not good, especially for the diagnosis of early lower grade bladder cancer.For bladder cancer, tumor tissue (puncture biopsy or surgical resection) DNA, urine ctDNA, urinary tract exfoliated cell DNA and peripheral blood ctDNA can be used for genetic testing, but the consistency of the genetic testing results of these four types of samples has not been verified, especially There is no systematic evaluation of the guidance effect of non-invasive gene detection of free tumor DNA and urinary tract shed cell DNA in the diagnosis and treatment of bladder cancer.The corresponding relationship between the significant mutation genes contained in the DNA derived from bladder urinary tract cancer and the various types and stages of bladder cancer is not clear.
The phase I/II study was designed to evaluate if the regimen of Irinotecan, Oxaliplatin, Capecitabine (XELOXIRI) and Bevacizumab is a superior first-line option for patients with metastatic colorectal cancer(mCRC) in terms of safety and efficacy.
To Observe the Efficacy and Safety of Pyrotinib Maleate in Patients With HER2-positive Advanced Colorectal Cancer
The purpose of this study is to determine the efficacy of adjuvant HIPEC with Mitomycin C after colectomy in the treatment of colorectal cancer patients at high risk of peritoneal carcinomatosis.
This is a single arm study to evaluate the efficacy and safety of CEA-targeted CAR-T cells therapy for patients with relapsed/refractory CEA+ Cancer,and obtain the recommended dose and infusion plan.
The current standard treatment for locally advanced rectal cancer is still fluorouracil-based neoadjuvant radiotherapy and chemotherapy followed by TME surgery, followed by adjuvant chemotherapy. Fluorouracil single-agent simultaneous sensitization of radiotherapy and chemotherapy has a pCR of about 15-20% and a tumor downgrade (ypStage 0-I) rate of about 35%. However, about 30% of patients still have distant metastasis, which is the main obstacle affecting the survival prognosis of patients with locally advanced rectal cancer. About 50% -65% of patients was still stage II-III after neoadjuvant therapy. The long-term follow-up shows that for patients with ypT4 after surgery, the 3-year DFS is about 50%. For patients with ypN2, the 3-year DFS is less than 40%. Therefore, it is necessary to strengthen postoperative adjuvant chemotherapy to improve the survival prognosis for these patients. Although FOLFOX adjuvant chemotherapy improved survival benefit than 5FU as adjuvant treatment in ypStage II-III patients after neoadjuvant treatment in ADORE trial. However, with the progress of neoadjuvant therapy research, more and more studies have proposed to move part or all of postoperative adjuvant chemotherapy to preoperative neoadjuvant therapy due to low compliance of adjuvant chemotherapy. During neoadjuvant treatment, induction chemotherapy with FOLFOX / CAPEOX or consolidation therapy after CRT with FOLFOX / CAPEOX had been investigated a lot. The pCR rate was 19% -38%, and the tumor downstaging rate was about 50%. Another 50% of patients still had ypstage II-III postoperatively. The 3-year DFS for ypStage III was only 55% even with FOLFOX as adjuvant chemotherapy. And for ypT4N0 patients with ypstage IIB-IIC, there is also a higher risk of recurrence and metastasis. And it is urgent to explore new treatment strategies to improve this part of patients Survival prognosis. For locally advanced colon cancer, surgery combined with postoperative adjuvant chemotherapy is currently the standard treatment mode for stage II-III colon cancer. About 30% of patients with locally advanced disease will relapse within 3 years, of which distant metastases are more common and eventually become the main cause of death of patients. For locally advanced colon cancer with a preoperative staging of T4b, the NCCN guidelines recommend surgery after neoadjuvant chemotherapy with FOLFOX or CAPOX regimens. In the FOxTROT study of neoadjuvant treatment of locally advanced colon cancer, for patients with T3> 5mm or T4, after 4 courses of neoadjuvant chemotherapy with FOLFOX regimen, 20.5% of patients still have T4 after surgery, and 15.2% of patients had N2 disease. For this part of patients, new postoperative treatment options should also be explored to improve patient survival and prognosis. In view of the high efficiency of the three-agent FOLFOXIRI regimen in advanced colorectal cancer and the success in adjuvant chemotherapy after pancreatic cancer surgery, 5FU, oxaliplatin combined with irinotecan may have a synergistic effect. At present, a phase III randomized controlled study (IROCAS study) in Europe is underway. For high-risk phase III patients, the mFOLFOXIRI regimen is compared with mFOLFOX6 regimen adjuvant chemotherapy. Based on the above reasons, our center plans to further carry out "multi-center, randomized, controlled phase III clinical study of mFOLFOXIRI versus mFOLFOX6 adjuvant chemotherapy after neoadjuvant oxaliplatin in locally advanced colorectal cancer." Improve the survival prognosis of postoperative high-risk colorectal cancer patients after neoadjuvant therapy.
This trial will determine the clinical effectiveness of polygenic risk score testing among patients at high genetic risk for at least one of six diseases (coronary artery disease, atrial fibrillation, type 2 diabetes mellitus, colorectal cancer, breast cancer, or prostate cancer), measured by time-to-diagnosis of prevalent or incident disease over 24 months.
The present study is aimed at detecting and measuring mRNA levels of genes involved in epithelial to mesenchymal transition (EMT) in biological samples, i.e. in peripheral blood samples of colorectal cancer (CRC) patients and healthy controls, to determine the presence of disease, its progression and risk of recurrence.
The investigators will expand an existing, patient-centered, health literacy strategy to promote longer-term adherence to colorectal cancer (CRC) screening in resource-limited, rural health clinics via colonoscopy or annual fecal immunochemical test (FIT). In the proposed 2-arm study, both PRIME-CRC and enhanced usual care (control) will incorporate health literacy evidence-based practices for delivering CRC patient information and counseling to aid patient decision making for selecting FIT or colonoscopy, including simplified test instructions. In addition, the PRIME-CRC arm will use a "stepped care" approach for reminding patients on proper CRC screening preparation for scheduled colonoscopy or completion of annual FIT. Patients in the PRIME-CRC arm will receive frequent follow-up contact from their health care provider via audio-recorded, automated call or SMS text, based on patient preference.
