Filter by:This is a prospective, multi-center, blinded feasibility study. The objective of this study is to test the feasibility of the detection of tumor DNA of a variety of tumors in peripheral blood using a novel process for the detection of circulating tumor DNA (ctDNA).
The vascular branches of inferior mesenteric artery (IMA) involve superior rectal artery(SRA),Sigmoid artery(SA) and the left colic artery(LCA). Different levels of ligation of the (IMA) are applied in rectal cancer surgery, including retain or not retain the left colic artery(LCA). Retained the LCA would facilitate the vascularity. The variations of vessels are more frequent in the combinations of branches, while LCA, SA and SRA may vary from people to people. Which contribute to the difficulty of surgery to retain the LCA.. As a result, a better understanding of the anatomical branches classification of IMA is a must during operation. However, existing studies of IMA's branches combination are very rare and often single-centered with minimal samples. In order to achieve better surgical outcome and reduce operative complications, the investigators design this study to investigate the anatomical classification of IMA and the surgical outcome of each type
Colorectal cancer will be resistant to Chemotherapy drugs after treated for a period of time .In the past, the classical treatment regiment was to change other drug after tumor progressed. In theory, the continuous use of such a drug could shortening the patient's drug resistance time. It has been shown that the alternate use of the two drug combinations is reasonable in clinical. This application can not only further improve the curative effect but also significantly reduce the side effects. So the investigators are going to carry out a prospective phase II clinical study. The control group change to second-line treatment after progression of first-line drugs. The experimental group use the first line and the second line,alternately, for every two cycles. The combination of bevacizumab is a first line development, and the second line can still be used . Objective to compare the clinical value of XELOX + bevacizumab and XELIRI + bevacizumab alternation regimen in the first-line treatment of advanced colorectal cancer.

The trial is a randomized control trial. Patients are randomized between Ltx and other treatment that may include further chemotherapy, TACE, SIRT or other available treatment options. The patients will be randomized 1:1 to Ltx and chemotherapy/other treatment options.
To evaluate the efficacy and safety of neoadjuvant FOLFOXIRI chemotherapy (irinotecan, oxaliplatin and fluorouracil) in the patients with resectable liver metastasis of colorectal cancer
1. Background Cetuximab (trade name Erbitux) is a murine-human chimeric monoclonal antibody to human epidermal growth factor receptor (EGFR). This drug has been used as a treatment for colorectal cancer and head and neck cancer. It is known that allergic reactions can occur in more than 5% of the patients, although the side effects are relatively low compared with other chemotherapeutic agents. It is known that cetuximab can induce hypersensitivity even at the first administration, unlike other anticancer drugs. In this study, we aimed to establish a model to predict patients with hypersensitivity reaction before administration of cetuximab and to provide safe chemotherapy. 2. Recruitment method and consent procedure The study is designed for analysis patients scheduled for administration of cetuximab for the first time. Patients matching the selection and exclusion criteria with voluntary agreement to the study will be enrolled. Enrolled patients will be tested for skin prick test and serum sIgE before cetuximab administration.
This trial will study tisotumab vedotin to find out whether it is an effective treatment alone or with other anticancer drugs for certain solid tumors and what side effects (unwanted effects) may occur. There are seven parts to this study. - In Part A, the treatment will be given to participants every 3 weeks (3-week cycles). - In Part B, participants will receive tisotumab vedotin on Days 1, 8, and 15 every 4-week cycle. - In Part C, participants will receive tisotumab vedotin on Days 1 and 15 of every 4-week cycle. - In Part D, participants will be given treatment on Day 1 of every 3-week cycle. Participants in Part D will get tisotumab vedotin with either: - Pembrolizumab or, - Pembrolizumab and carboplatin, or - Pembrolizumab and cisplatin - In Part E, participants will receive tisotumab vedotin on Days 1 and 15 of every 4-week cycle. - In Part F, participants will receive tisotumab vedotin on Days 1, 15, and 29 of every 6-week cycle. Participants in Part F will get tisotumab vedotin with pembrolizumab. - In Part G, participants will receive tisotumab vedotin on Days 1, 15, and 29 of every 6-week cycle. Participants in Part G will get tisotumab vedotin with pembrolizumab and carboplatin.
Background: Chemotherapy treatment (CT) can have burdensome side effects such as fatigue, nausea-vomiting, and sleep problems that can significantly affect patients' quality of life. Fatigue is the most common, lasting and bothersome of these, which prevents people from working and carrying out daily activities. Mindfulness-Based Cancer Recovery (MBCR) is an evidence-based group training program which has shown to help treat negative physical and psychosocial symptoms in cancer patients. The investigators propose to evaluate a pilot-tested online-MBCR program for patients undergoing CT who may be low on energy, time or have compromised immunity. Objectives: To evaluate the impact of participation in online MBCR during CT on fatigue (primary outcome), sleep, pain, nausea/vomiting, mood disturbance, stress symptoms and quality of life (secondary outcomes) as well as cognitive function and return to work (exploratory outcomes) over the course of treatment. Methods: The study design is a randomized wait-list controlled trial, conducted during CT for patients with breast or colorectal cancer. Participants will take the 12-week online MBCR program at home within 2 weeks of randomization (immediate group) or after CT completion (waitlist group). Outcomes will be assessed online at, 1) Baseline, 2) Post-MBCR, 3) Post-CT (primary outcome) and 4) 12 months post-baseline. Anticipated Findings: MBCR is a promising adjuvant program that could help patients prevent, delay or diminish aversive symptoms and side-effects associated with CT, particularly fatigue. If helpful, online-MBCR could be made easily available at cancer centers worldwide and significantly lessen the burden of cancer treatments.
Colorectal cancer (CRC) is among the most preventable cancers when precancerous lesions are detected at an early stage. Current screening methods for CRC require bowel prep or stool-based testing that are inconvenient, resulting in low compliance. Stool based tests have limited sensitivity for the detection of precancerous lesions. The CMx platform has been showed to be able to the detection of Circulating Tumor Cells (CTCs) in high sensitivity and specificity. In published studies, circulating Tumor Cells (CTCs) are captured and quantified in advanced-stages of colorectal cancer. In order to detect early and pre-cancer circulating tumor cells, we have developed an Automated Liquid Biopsy Platform that improves the detection of CTCs in early cancer stages. Therefore, this study goals are: 1) to establish a standard detection process utilizing the Automated Liquid Biopsy Platform. 2) Parallel comparison of laboratory manual operation and Automated Liquid Biopsy Platform. 3) Verify the feasibility of use of an Automated Liquid Biopsy Platform in the clinical setting.
