Filter by:Part 1: This clinical study will first test the safety and initial effect on the tumour of PS101-mediated ACT when given in combination with standard of care chemotherapy in patients with liver metastases (initially those with any solid tumors and then further in patients just with colorectal cancer [CRC]) in order to identify the recommended dose and schedule of PS101-mediated ACT that can be taken forward for further testing. Part 2: Based on the Part 1 results, another part in patients with liver metastases from CRC and pancreatic cancer (if indicated) may take place following a substantial protocol amendment. This record will focus on Part 1 of the study only and will be updated if Part 2 occurs.
Colorectal cancer is among the most common types of cancer worldwide. Population-based screening programs for breast, cervical, and colorectal cancer have been introduced as part of cancer control in many high-income countries. Population-based cancer screening programs do not exist in most low- and middle-income countries. There are some studies that report the awareness of colorectal cancer in Turkey.
This phase I/II trial studies the best dose and side effects of encorafenib, cetuximab, and nivolumab and how well they work together in treating patients with microsatellite stable, BRAFV600E gene mutated colorectal cancer that cannot be removed by surgery (unresectable) or has spread to other places in the body (metastatic). Encorafenib and cetuximab may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Immunotherapy with monoclonal antibodies, such as 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 encorafenib, cetuximab, and nivolumab may work better in treating patients with colorectal cancer compared to cetuximab alone.
The primary objective of this study is to assess the safety and tolerability and to determine the recommended Phase 2 dose (RP2D) of E7386 in combination with other anticancer drug(s).
Colonic Laterally spreading lesions (LSL) => 20mm are at high risk to progress to cancer. Overt stigmata of submucosal invasive cancer (SMIC) has been well characterized and includes ulceration and surface pit pattern changes as per the Kudo classification of type V. In a recent report, risk factors for LSL with SMIC and no overt stigmata (i.e. covert SMIC) were described. Resection of these lesions 'en-bloc' can allow for better histological staging and potentially reduce the need for surgical resection.
The main purpose of this study is to compare the clinical benefit, as measured by Progression-Free Survival (PFS), Objective Response Rate (ORR), and Overall Survival (OS), achieved by nivolumab in combination with ipilimumab or by nivolumab monotherapy in participants with Microsatellite Instability High (MSI-H) or Mismatch Repair Deficient (dMMR) metastatic colorectal cancer (mCRC). This study will also compare nivolumab plus ipilimumab combination vs chemotherapy for treatment of MSI-H/dMMR mCRC participants.
Intro: Recent studies on colorectal cancer surgery have been focusing on the role of intestinal microbiome on surgical outcomes. Standard perioperative cares, like mechanic bowel preparation (MBP), administration of antibiotics (ABT) and surgery-related stress and injury influence the microbiome composition and possibly induce a shift toward a microbiome dysbiotic state, which predisposes to complicated postoperative course. Microbiome composition changes and enhanced virulence factors may increase the risk of postoperative complications, such as anastomotic leakage (AL), surgical site infection (SSI), and postoperative ileus (PI), which are known to impact on patient's overall survival and cancer recurrence. Objective: The primary objective is to investigate if a significant association might exist between the microbiome composition and the occurrence of postoperative complications at 90 days. Methods: 3 different microbiome samples will be taken from all patients. Two fresh fecal samples for detection of LM and fecal water preparation: a) a day before the surgery before MBP and/or ABT (LM1), b) postoperatively after first bowel movement (LM2). One sample will be taken intra-operatively from the stapled resection lines of circular stapler used for forming a colorectal anastomosis, to detect the MAM and to perform immunohistochemistry staining for detection of HACE1 expression. DNA analysis will be performed for all samples. IHC will be performed for detecting HACE1 expression in the tumor and colorectal anastomosis tissues using anti-HACE1 antibodies. . For proliferation assessment, human colon carcinoma cell lines HT29 will be plated in monolayers and scratched with a single scratch. Monolayers will be incubated for 24 hours with fecal water from patients with surgical complications and matched control patients without complications. Descriptive statistics will be performed to describe the study population. This project aim to describe microbiome composition and its impact on postoperative complications.
Recruit of healthy, precancer and colorectal cancer patients and record necessary information of demographic and also other messages. All the volunteers were asked to provide samples including stool, blood, urine and tissues. This protocol is performed with the permission of the ethics committee and all the participants were provided with informed consent.
This study will examine the association between low muscle mass (myopenia) at diagnosis and chemotherapy toxicity in older adults with newly diagnosed advanced colorectal cancer.
This is a window of opportunity translational study investigating the use of pre-operative pembrolizumab and chemotherapy or chemoradiotherapy in non-metastatic colorectal cancer.
