The study is a cross-sectional survey study targeting patients aged 45-75 who had their screening or surveillance colonoscopy postponed or delayed due to the COVID pandemic. Study staff will survey a random subsample of patients to assess anxiety, COVID risk tolerance, cancer worry, willingness to screen and barriers to screening colonoscopy, and preference for colonoscopy and alternative colon cancer screening options. Eligible patients will be sent a survey packet in the mail that will include a cover letter, an information sheet describing the study, an incentive, and the survey. The cover letter will include information for participants to opt-out if they desire. Patients will be asked to complete the survey and return it back to study staff. Consent is implied with return of the survey. For the study, staff plan to invite 300 patients and expect to receive 195 completed surveys. Analyses will examine whether COVID-19 has changed patients' interest in colon cancer screening and the strength of patients' preferences for colonoscopy and other approaches to colon cancer screening. It will then examine factors associated with positive and negative views on rescheduling colonoscopies such as anxiety, worry, and risk perceptions.
The aim of this trial is to evaluate the value of palliative primary tumor resection in colon cancer patients with initially unresectable metastases and a positive response to induction chemotherapy which depends on gene testing. The primary endpoint is to evaluate overall survival.
According to general medical guidelines, adjuvant chemotherapy is used after curative resection of high-risk stage II or III primary colon cancer. However, there exist limitations using clinical trial data acquired from highly selected subjects in a controlled environment. For example, patients aged over 70 years old were in many cases excluded from clinical trials resulting in insufficient data on the efficacy of therapies including oxaliplatin in aged patients, and the source data of the medical guidelines did not fully reflect the conditions of Korean patients. In addition, suggestions are continuously being submitted for existing therapies with modified administration periods and methods with the aim to search for the optimum effect over side effects. Discussions are also held on meta analyses results that imply the need to apply slightly different approaches through small groups of patient and disease factors. As there are more diverse adjuvant therapy protocols that can be applied to post-surgery colon cancer patients, it is necessary to figure out the patterns of adjuvant chemotherapies actually used in Korean medical practices. Also, in order to complement the limitation of external validity of the existing base clinical data, a multifaceted exploratory analysis will be conducted by making follow-up observations on patterns, prognosis results, quality of life, adverse effects, etc. of post-surgery adjuvant chemotherapies actually used in around 30 sites in Korea under the noninterventional observational study conditions.
To confirm the safety and performance of the da Vinci SP Surgical System, Instruments and Accessories in a complex colorectal procedure such as low anterior resections or right colectomy.
The main purpose of this study is to investigate whether magnetic ressonance imaging (MRI) can be used in treatment planning with assessment of diagnostic accuracy. With the inclusion of 150 patients the study will investigate whether MRI is useful and better than CT scanning in patients with colon tumors. And also if MRI is useful after neoadjuvant treatment.
According to the 2019NCCN guidelines, immunocheckpoint inhibitors are recommended for first-line treatment of metastatic colon cancer patients with high microsatellite instability (msi-h) or mismatched gene deletion (dMMR) who are not suitable for intensive treatment, and for all patients with second-line or above msi-h /dMMR treatment.This study is a single-center, single-arm phase II study of the use of triplezumab (JS001) combined with CAPEOX regimen in the neoadjuvant therapy of msi-h /dMMR for locally advanced colon cancer. The subjects received neoadjuvant therapy with triplezumab (JS001) combined with CAPEOX regimen, with one treatment cycle every 3 weeks and two cycles of surgery followed by pathological evaluation.
The PREEMPT CRC study is a prospective multi-center observational study to validate a blood-based test for the early detection of colorectal cancer by collecting blood samples from average-risk participants who will undergo a routine screening colonoscopy.
The efficiency of the D3 lymph node dissection is still controversial for left colon cancer patients. This study will try find difference in 5-year overall survival between D2 and D3 lymph node dissection. Investigation of the functional and short-term outcomes will clarify safety of the D3 lymph node dissection.
This phase I trial studies the side effects and best dose of regorafenib when given together with ipilimumab and nivolumab in treating patients with microsatellite stable colorectal cancer that has spread to other places in the body (metastatic) and remains despite chemotherapy treatment (resistant). Regorafenib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Immunotherapy with monoclonal antibodies, such as ipilimumab and nivolumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving regorafenib, ipilimumab and nivolumab may slow the tumor growth and/or shrink the tumor size in patients with colorectal cancer.
