Filter by:A open label 1:1 randomized phase II exploratory study investigating adjuvant therapy in patients with molecular biologically detectable residual disease after primary resection for localized colorectal tumors.
The main aim of this study is to determine whether the assessment of the invasive pattern based on NBI with dual focus/magnification or BLI with magnification ± chromoendoscopy (NBI+CE) for predicting deep invasion is significantly more accurate than the assessment based on white light endoscopy (WLE), carried out by trained endoscopists.
Adjuvant chemotherapy was unnecessary in pathological stage Ⅱ colorectal cancer following initial treatment of surgery without high risk factors of recurrences. The treatment efficacy of adjuvant chemotherapy for pT1-3N0M0 colorectal cancer following preoperational chemotherapy or chemoradiotherapy remains unclear. Part of clinical local advanced colorectal cancer(cTxN1-2M0), which turn out to be pT0-3N0M0 after preoperational chemotherapy or chemoradiotherapy, might not really need adjuvant chemotherapy due to the down-stage efficacy of the preoperational treatments, or the misleading by lymph nodes false-positive imaging diagnosis.
Colorectal cancer (CRC) is one of the most common types of cancer worldwide in general and in Jordan in specific. The studies that investigate the role of Probiotics supplementation in improving the inflammatory response, gastrointestinal toxicity and life quality of patients with colorectal cancer during radiotherapy are limited. So, this study aimed to study the effect of probiotics on the response of inflammatory markers, gastrointestinal toxicity, and quality of life in patients with colorectal cancer during radiation therapy. An interventional double-blind randomized clinical trial (RCT) design will be used in this study. Forty patients will be recruited and assigned either to receive 3 times a day probiotic supplement or to be control with no intervention. The demographic data, anthropometric measurements, Cancer Quality of Life Questionnaire and blood samples will be collected at baseline and at end of radiation therapy. Interleukin-6, interleukin-1,interleukin-10 IL-10, C-reactive protein, tumor necrosis factor-alpha and complete blood count (CBC) will be measured. The results will approve or disapprove the beneficial effect of using probiotics as adjuvant therapy for CRC patients and other types of cancer to reduce the side effects of radiotherapy and raise body weight as well as improving their quality of life.
Studies have shown that tumors from the same patient may respond very differently to the same therapeutic agents. This study aims to investigate the genetic basis of tumors that respond abnormally well or poorly to therapeutic agents in an effort to understand the fundamental genetic basis of this response. The present protocol seeks to retrospectively perform Exome, next-generation (DNA) sequencing and/or other molecular techniques on tumor samples to identify the genetic basis of a patient's exceptional response to chemotherapy.
This study is a first in human Phase 1 study that involves patients with a type of cancer called HER2 (Human Epidermal Growth Factor Receptor 2) positive cancer. This study asks patients to volunteer to take part in a research study investigating the safety and efficacy of using special immune cells called HER2 chimeric antigen receptor specific cytotoxic T lymphocytes (HER2 specific CAR T cells), in combination with intra-tumor injection of CAdVEC, an oncolytic adenovirus that is designed to help the immune system including HER2 specific CAR T cell react to the tumor. The study is looking at combining these two treatments together, because we think that the combination of treatments will work better than each treatment alone. We also hope to learn the best dose level of the treatments and whether or not it is safe to use them together. In this study, CAdVEC will be injected into participants tumor at one tumor site which is most easiest to reach. Once it infects the cancer cells, activation of the immune response will occur so it can attack and kill cancer cells. (This approach may have limited effects on the other tumor sites that have not received the oncolytic virus injection, so, patients will also receive specific T cells following the intratumor CAdVEC injection.) These T cells are special infection-fighting blood cells that can kill cells infected with viruses and tumor cells. Investigators want to see if these cells can survive in the blood and affect the tumor. Both CAdVEC and HER2-specific autologous CAR T are investigational products. They are not approved by the FDA.
This is a multicenter, clinical study. This study is to evaluate the sensitivity of plasma ctDNA methylation haplotypes in detecting colorectal cancer, adenoma and the specificity in healthy individuals.
This is a prospective, multicenter, observational, single-blinded controlled study. Dynamic monitoring of patients with resectable colorectal cancer was performed using the previously established colorectal tumor-specific plasma ctDNA methylation markers (Multigene methylation detection). Dynamic monitoring of plasma ctDNA methylation before and after treatment and at regular follow-up in patients with colorectal cancer after radical resection of tumor, to explore the predictive effect of postoperative plasma ctDNA methylation on postoperative recurrence and whether dynamic monitoring of postoperative ctDNA methylation could be earlier than imaging examination to indicate tumor recurrence.
This study is to evaluate diagnostic performance, safety and timing of post-dose imaging of ONM-100, an intraoperative fluorescence imaging agent for the detection of cancer in patients with solid tumors undergoing routine surgery.
The purpose of this study is to evaluate the safety, tolerability and pharmacokinetics, and determine the maximum tolerated dose of ZSP1241 in participants with hepatocellular carcinoma, cholangiocarcinoma, gastric cancer, esophageal cancer, colorectal cancer and other advanced solid tumors.
