Filter by:The protein tyrosine kinase-7 (PTK7) is overexpressed in various types of human cancers. As a specific imaging agent of PTK7, 68Ga-Sgc8 was investigated in this study to assess its safety, biodistribution and dosimetric properties in healthy volunteers, and to preliminarily evaluate its application in colorectal patients.
In colorectal surgery about 30% of postoperative mortality is attributed to anastomotic leak, whit an incidence range between 1.8% and 15.9%. Preventing the anastomotic leak can therefore bring benefits to the patient and the health system. To date we have technologically advanced suturizers and the correct realization (well-vascularized margins, not in tension, etc.) remains crucial to prevent anastomotic dehiscence. Experimental results demonstrate that modified cyanacrylate is a suitable potential "reinforcement" on intestinal anastomoses (manual or linear intra-corporeal). Applied after mechanical anastomosis, it polymerizes in a short time, closing the spaces of the suture line between one point and the other, expressing an adhesive, hemostatic and sealing action on the tissues, also creating an effective antiseptic barrier towards of the most common infectious or pathogenic agents.
Background: Many people with colorectal cancer get liver metastases. Standard treatment for this is a combination of chemotherapy drugs. Directing the chemotherapy to the liver may be effective. A device that does this a pump that delivers drugs over 2 weeks at constant rate into the hepatic artery. The person s body temperature causes the drug to flow from the pump. Researchers want to see if this helps people with colorectal metastases to the liver. Objective: To study the effectiveness of a hepatic artery infusion pump at treating colorectal metastases to the liver. Eligibility: Adults at least 18 years old with colorectal metastases to the liver Design: Participants will be screened with: Medical history Physical exam Heart, blood, and urine tests Scans Participants will stay in the hospital a few days. A small plastic tube (catheter) will be inserted in an artery into the liver. The catheter will be attached to the pump. That will lie under the skin on the abdomen. It will be small and participants will be able to feel it. Participants will get treatment in 28-day cycles. Every Day 1, they will have physical exam, symptom review, and blood tests. Every 2 weeks, they will come to the clinic to get chemotherapy by a catheter or port. Every 12 weeks, they will have a scan. Tissue samples may be taken during the study. When they finish the drug, participants may have the pump removed. They will repeat the Day 1 tests. They will be called every 6 months to see how they are doing.
To evaluate the efficacy and safety of Huaier granules for Prevention of Recurrence and Metastasis of colorectal cancer patients following radical surgery
30 patients with advanced colorectal cancer will be enrolled to observe the efficacy and safety of raltitrexed combined with apatinib as a third-line treatment.
The surgical therapeutic effect of stage II-IV CRC patients will be assessed by the plasma mSEPT9 assay, and patients will be followed up by the same assay for recurrence monitoring.
This trial aims to evaluate the efficacy, safety of high-dose FOLFIRI regimen in advanced colorectal cancer patients with wild-type UGT1A1*6 and *28.
By monitoring the serum ctDNA mutational profile using NGS, the present clinical trial aims to elucidate the correlation between the postoperative ctDNA status and the prognosis of patients with early and intermediate-stage colorectal cancer, and explore the possibility of clinical utility of serum ctDNA as a clinical index to predict postoperative relapse.
Molecular pathology of Colorectal Cancer: Investigating the role of novel molecular profiles, microRNA's and their targets in Colorectal Cancer progression
Natural killer cells (NK cells) are cytotoxic lymphocytes that play an important role in the innate immune system. In particular, it plays a very important defense function against host cells or cancer cells infected with a specific virus. Recent studies have shown that the activity of NK cells is decreased in patients with various carcinomas compared with normal controls, suggesting that the measurement of activity of NK cells in the blood may be helpful in the early diagnosis of cancer. In a recent study analyzing NK cell activity in 762 patients undergoing colonoscopy, NK cell activity showed performance in diagnosing advanced colorectal adenoma and colorectal cancer with sensitivities 42.2% and 85.7%, and specificity 58.3% and 59.5%, respectively. This finding suggests that NK cell activity may be useful as a screening method for colorectal neoplasms. However, as a single test, this diagnostic power is relatively low. On the other hands, another blood-based colorectal cancer screening test that using 29 gene panels algorithm has recently been reported. According to this study, 29 gene panel algorithms (Colox®) showed performance in diagnosing advanced colorectal adenoma and colorectal cancer with sensitivity of 55.4% and 79.5% and specificity of both 90.0%, respectively. for diagnosis of advanced adenoma and colorectal cancer, respectively. Although the Colox® test seems to be useful for the colorectal cancer screening using blood test, this diagnostic power is relatively low. In order to overcome low diagnostic performance of aforementioned tests (NK activity and Colox®) as a single use, combination of individual biomarkers can be a promising alternative. In this regards, the aim of this study was to evaluate the diagnostic value for predicting advanced colorectal neoplasms by combining Colox® and NK cell activity indicators.
