Filter by:To measure the level of circulating tumor DNA (ctDNA) in the blood of colorectal cancer patients after 6 months of receiving therapy with regorafenib and XmAb20717 (also known as vudalimab). ctDNA is genetic material from tumor cells that can be found and measured in the blood
The purpose of this study is to use the SignateraTm assay created from rectal tumor biopsies to monitor participants' blood for fragments of DNA shed by tumor cells. The tumor DNA fragments are referred to as circulating tumor DNA, or ctDNA for short.
The primary aim of this study is to collect clinical data on the performance of MonoPlus® suture applied in routine clinical practice. Diverse parameters are to be used to assess the safety and efficacy of MonoPlus® suture for gastrointestinal anastomosis construction. This study has been designed to implement an action within the framework of a proactive Post Market Clinical Follow up (PMCF) activity.
This is a single-arm observational study to determine the feasibility of assessing tumor response utilizing Circulating tumor DNA (ctDNA) in patients of with locally advanced rectal cancer (LARC) undergoing standard-of-care total neoadjuvant therapy (TNT) consisting of systemic chemotherapy (modified FOLFOX or modified FOLFIRINOX) followed by concurrent chemoradiation (50.4 Gy over approximately six weeks with concurrent radiosensitizing dose of capecitabine/5-fluorouracil).
Prospectively Investigate the effectiveness and safety of anlotinib hydrochloride combined with Capeox in neoadjuvant treatment of patients with locally advanced rectal cancer.
This study is a prospective, single-arm, single-center study of investigator's choice of total neoadjuvant therapy (TNT) or neoadjuvant chemoradiation in locally advanced rectal cancer. The standard of care for rectal adenocarcinomas that are triiodothyronine-thyroxine (T3-T4) or node positive has generally been comprised of neoadjuvant chemoradiation, followed by surgical resection and then adjuvant chemotherapy. More recently, TNT, comprised of neoadjuvant chemotherapy and chemoradiation followed by surgical resection, has been increasingly used as a standard therapy approach. While the use of TNT is increasingly common, prospective study of outcomes following TNT has been limited. Moreover, there are not any biomarkers known at this time that impact clinical decision-making or personalization of therapy in the treatment of rectal cancer. In this study, we will collect pre-treatment rectal adenocarcinoma specimens and determine clinical outcome, including pathologic complete response rate, post-treatment pathologic downstaging rate, recurrence-free survival (RFS), overall survival (OS) and neoadjuvant rectal score, among patients who are treated with standard neoadjuvant chemoradiation or TNT, with an aim to investigate how baseline biomarkers and changes in biomarkers with standard therapies may be associated with, and modulate, clinical outcomes.
This pilot study will aim to determine the feasibility, safety, and cost associated with a preoperative VLED for obese rectal cancer patients. Ultimately, the investigators seek to provide evidence that may inform the development of a standardized preoperative weight loss protocol in obese rectal cancer patients.
The primary purpose of this registry is to prospectively collect data from different Mini-invasive Colo-rectal Units in Northern Italy with a standardization of the pre-operative, intra-operative and post operative setting for patients operated on for non metastatic rectal cancer with curative intent. The secondary aim is to collect in a registry the compliance to oncological treatments and the oncological outcomes for the same patients
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.
This study is designed to evaluate the short-term and long-term results after single incision laparoscopic surgery for colorectal cancer（SILSC） compared with conventional laparoscopic surgery for colorectal cancer（CLSC）.
