Quality of Life After Cytoreductive Surgery and Intraperitoneal Chemotherapy
Colorectal Cancer MetastaticCytoreductive surgery with intraperitoneal chemotherapy is one of the most important treatments for patients with colorectal cancer and peritoneal metastasis. For the best survival rates, complete removal of all metastatic lesions is the most important part of treatment, and various surgical procedures are required for the complete cytoreduction. Therefore, the postoperative morbidity rates are higher than those of localized colon cancer surgeries and patients can experience a prolonged recovery period and deterioration of physical activities over a long period. The aim of this study is to investigate the change of quality of life after cytoreductive surgery and intraperitoneal chemotherapy for colorectal cancer.

Sym004 in Metastatic Colorectal Cancer and ECD-EGFR Patients
Metastatic Colorectal CancerThis is a single arm, phase 2, open-label, multicenter trial in patients with metastatic colorectal cancer (mCRC) and acquired resistance to anti-epidermal growth factor receptor (EGFR) monoclonal antibodies (mAbs) and documented mutation of extra cellular domain EGFR (ECD-EGFR).

Treatment Response Prediction System of mCRC Patients Based on CTC
Colorectal Cancer Stage IVCirculating Tumor CellThis study enrolling patients with metastatic colorectal cancer. Detecting CTC at different points in the treatment process. Descripting the molecular atlas of CTC in mCRC patients. Building and validating a response prediction system of mCTC patients.

The Role of Fluorothymidine Positron Emission Tomography (FLT-PET) in Proliferation of Colorectal...
Colorectal NeoplasmsLiver NeoplasmsThe aim of the study is to obtain information on FLT used in a PET-scan as a marker for the proliferation of colorectal liver metastases, so that the risk of recurrence can be identified in a noninvasive way, concerning patients with resectable colorectal liver metastases. The hypothesis of this study is that a higher uptake of FLT in the liver metastases has a good correlation with the proliferation rate of the metastases. This rate is related to the risk of recurrence.

An Observational Study to Learn More About the Long-Term Responses to Treatment With Regorafenib...
Metastatic Colorectal CancerThis is an observational study in which data already collected from patients with metastatic colorectal cancer will be studied. Metastatic colorectal cancer (mCRC) is a cancer of the colon (large bowel) or the rectum (lowest part of the bowel just before the anus) that has spread to other parts of the body. The study drug, regorafenib, is already approved for cancer doctors to prescribe to patients with mCRC. It is an anti-cancer drug that blocks several proteins, called enzymes, which are involved in the growth of cancer. The participants in this study were treated with regorafenib as part of their regular care from their doctors. Some studies have shown that patients with mCRC who took regorafenib had improved survival outcomes, and some of them did well on the treatment for a long time. Cancer doctors have also reported from their routine practice that some patients with mCRC are able to respond to regorafenib for a longer period than others. However, there is limited knowledge about which people this is likely to happen for. To better understand the long-term response of regorafenib treatment, there is a need for a large-scale study in the real world. The main purpose of this study is to learn more about patients who showed a long-term response to regorafenib as a mono treatment for mCRC. To do this, researchers will collect the following information from the participants' health records: Duration of treatment with regorafenib Percentage of participants who received treatment with regorafenib for at least 5 months and 4 months. Characteristics, including age, sex, race, health condition, and signs and symptoms of mCRC, of participants who received treatment with regorafenib for at least 5 months and 4 months. The data will come from an electronic health records database called the Flatiron Health Data Repository for patients in the United States. The data will be from patients with mCRC who started treatment with regorafenib between July 2013 and December 2022. Researchers will consider the data of the participants collected until May 2023. In this study, only available data from routine care are collected. No visits or tests are required as part of this study.

An Observational Cohort Study to Assess the Postop Activity of Colorectal Patients Undergoing Elective...
Colorectal (Colon or Rectal) CancerAll participants will have a physical activity monitor placed onto the right thigh in the midline which will start collecting data at midnight on the first postoperative day. This will continue until discharge or day 7, whichever is earlier. This is a non-invasive measure of activity and can discriminate between whether a patient is lying, sitting, standing or walking. There is no control group.

Examination of Trends in Colorectal Cancer Patients' Clinical Study Experiences
Colorectal CancerClinical study participation percentages haven't always been fully representative of a given demographic. Participation in this observational clinical research is extremely valuable since it allows people with colorectal cancer to contribute their own experiences and unique viewpoints. These vital contributions have the potential to affect the development of novel therapies and support services dramatically. Trial's findings will be critical in furthering the understanding of colorectal cancer, ultimately leading to better patient outcomes.

The Predictive Value of Guangzhou Panel for Recurrence in Early-stage Colorectal Cancer
Colorectal NeoplasmsThis study aims to evaluate the predictive value of a four-gene methylation assay called Guangzhou Panel in early-stage colorectal cancer. Patients will be divided into two groups: high risk group and low risk group. The primary endpoint is 5 year disease free survival (DFS).

Colorectal CancerLung MetastasesThe investigators will detect circulating tumor DNA in blood of patients with lung metastases from colorectal cancer using NGS technology and intend to use it for predicting the outcome of local treatment (surgery or radiation) and recurrence of lung metastases.
