Filter by:In this research study, the investigators are looking to see if the circulating tumor DNA (genetic material), also known as ctDNA, in the blood will help them predict whether the participant's cancer will come back.
The primary objective of this sub-study, 2018-10B, is to collect blood specimens to assess new biomarkers for the detection of Colorectal Cancer (CRC).
Protocol Title: Evaluation of safety, usability and subject compliance while using Check- Cap's C-Scan System for providing structural information on colonic polypoid lesions and masses Study Design: Prospective, Multi-center, Single-arm, safety study Purpose: To demonstrate the safety of the Check-Cap C-Scan System Study Centers: Up to two (2) centers located in the United States Number of Participants: 45 healthy subjects Investigational Device: Check-Cap's C-Scan System comprises C-Scan Capsule, C-Scan Track and C-Scan View. Primary Objective: To evaluate the safety of the Check-Cap C-Scan System Secondary Objectives: a. To evaluate subject's compliance b. To evaluate subject's satisfaction c. To collect data to improve the product's algorithm
How to reduce the complications of perineal wound after abdominoperineal resection (APR) has always been a hot topic in the medical field.To reduce the complications of perineal wound and the primary healing of perineal wound must meet the two principles of "unobstructed drainage" and " reduced tension closure".This concept is similar to the concepts of closure of enterostomy in rectal cancer patients. It was reported that use of cross-stitch closure can significantly reduce complications of closure of enterostomy. So the investigator ever used the "cross" closure to reconstruct the perineal wound of APR, which was really decrease the complications of perineal wound. However, more clinical trails was needed to confirm the conclusion.
Observational study to evaluate longitudinal quality of life according to standardized EORTC questionaires as well as functional Outcome, oncological outcome and toxicity in patients treated with neoadjuvant short term radiation or long-term chemoradiation followed by surgery
Patients with a primary rectal cancer without detectable distant metastasis who after locoregional therapy only, meaning preoperative radio(chemo)therapy plus surgery have at least a 40% risk of not having a CRM negative resection or a recurrence, local or distant, within three years will be treated with the short course 5 x 5 Gy radiation scheme followed by four cycles of combination chemotherapy (capecitabine and oxaliplatin) and TME surgery
A randomized controlled clinical trial to compare the short and long term outcomes of left colic artery preservation for the treatment of Rectal Cancer
Transanal endoscopic microsurgery is the main treatment option for rectal tumors such as large adenoma, early cancer because of lower complications and mortality rates and shorter hospital stays rather than conventional surgery. Particularly, However, transanal endoscopic microsurgerymust be performed under either general or spinal anesthesia, and expensive surgical instruments are required. Colorectal endoscopic submucosal dissection is a novel endoscopic procedure that enables en bloc resection of benign colorectal lesions and early colorectal cancer. Endoscopic submucosal dissectioncan be performed under conscious sedation without anesthesia, and there are fewer hospital days than those for transanal endoscopic microsurgery. In the present study, we compared the treatment efficacy and safety between endoscopic submucosal dissectionand transanal endoscopic microsurgery for the treatment of early rectal neoplasms and large rectal adenomas.
Improvements in downstaging are required when using preoperative chemoradiation for unresectable rectal cancer. There is therefore a need to explore more effective schedules. The study arm will receive MRI simulation-guided boost in short-course preoperative radiotherapy followed by consolidation chemotherapy , which may enhance the shrinkage of tumor comparing with the concurrent chemoradiation.
The study evaluates the addition of Amifostine to capecitabine and irinotecan in neoadjuvant chemoradiation(CRT) in locally advanced rectal cancer. Half of participants will receive capecitabine and along with neoadjuvant radiotherapy, followed by a cycle of XELIRI, while the others will receive capecitabine and irinotecan added by amifostine during CRT, followed by a cycle of XELIRI. All participants will be scheduled to receive surgery 6-8 weeks after the completion of CRT. Then it will depends which regimens the patient would receive according to his or her pathological results.
