Colectomy is the most commonly used therapeutic approach for the treatment of non-metastatic colorectal cancer. This approach is generally very effective however the rate of recurrence and the appearance of metachronous metastasis remains a major problem in the postoperative period. One of the hypothesis that can explain this tumor progression is the dissemination of tumor cells at the time of tumor mobilization. In this work, we wish to verify this hypothesis by comparing two surgical technics used in our department for left or right colectomies: respectively either first section of the mesenteric vessels followed by the mobilization of the tumor or first mobilization of the tumor followed by the section of the mesenteric vessels. To evaluate the dissemination, we will study two disseminations markers that have shown their prognostic value: i) circulating tumor cells (which represent a direct marker of dissemination) and ii) tumor circulating DNA (which is an indirect marker) but has the advantage of being more representative of all tumor clones and therefore the tumor burden released into the blood at the time of surgery).
Colorectal cancer is the third most common cancer worldwide. These patients usually undergo open surgical resection of cancer under general anaesthesia. The aim of this study is to detect whether the Erector spinae plan block or Quadratus lumborum block will provide the most ideal analgesia for these patients. Erector spinae plan block is a novel analgesic technique that provides both visceral and somatic analgesia due to its communication with the paravertebral space. Quadratus lumborum block is a truncal nerve block usually used for intra-abdominal surgeries. Ultrasound guidance increases the accuracy and safety of both techniques. A local anaesthetic mixture of Bupivacaine 0.25% and dexamethasone will be used for both techniques.
This study is evaluating the combination of Y-90 radioembolization followed by SBRT with the immunotherapy drugs, durvalumab and tremelimumab, to improve disease control of liver metastases for patients with microsatellite stable colorectal cancer.
This study will determine the pharmacodynamically-active dose of gevokizumab and the tolerable dose and preliminary efficacy of gevokizumab in combination with the standard of care anti-cancer therapy in patients with metastatic colorectal cancer, metastatic gastroesophageal cancer and metastatic renal cell carcinoma.
The purpose of this study is to determine the safety and efficacy of combination therapy with pembrolizumab (MK-3475) and lenvatinib (E7080/MK-7902) in participants with triple negative breast cancer (TNBC), ovarian cancer, gastric cancer, colorectal cancer (CRC), glioblastoma (GBM), or biliary tract cancers (BTC). Participants will be enrolled into initial tumor-specific cohorts which will be expanded if adequate efficacy is determined.
Gastric cancer is a global health threat. Helicobacter pylori is now recognized as the main risk factor that initiates this process; hence, H. pylori eradication has been considered the most effective method to ameliorate the burden of gastric cancer. Serum pepsinogen levels reveal the current atrophy of the stomach and predict gastric cancer risk. A risk prediction model with the combination of H. pylori infection and serum pepsinogen level could identify the highest-risk gastric cancer patients. Colorectal cancers (CRC) rank second and third as the leading causes of cancer-related death in men and women, respectively. For CRC prevention, a two-stage approach using the fecal immunochemical test (FIT) is popular; besides, the FIT levels may serve as a guide for priority setting in prompting residents to undergo colonoscopy. Therefore, the effectiveness and utility of aggressive referral confirmatory diagnosis protocol in a colorectal cancer screening program for those with high FIT levels urgently need to evaluate.
This study is a two-arm, randomized controlled trial, comparing the effects of a 12-week group-based physical activity intervention to a 1:1 supervised physical activity (i.e. personal training) on long-term physical activity adherence.
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 pT1-3N0M0 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.
This study involves patients with a type of cancer called HER2 (Human Epidermal Growth Factor Receptor 2) positive cancer. Because there is no standard treatment for this cancer at this time or because the currently used treatments do not work fully, 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-modified Adenovirus-specific cytotoxic T lymphocytes (HER2-AdVST), in combination with intra-tumor injection of CAdVEC, an oncolytic adenovirus that is designed to help the immune system including HER2-AdVST react to the tumor. The body has different ways of fighting infection and disease. No single way seems perfect for fighting cancers. This research study combines two different ways of fighting cancer: oncolytic adenovirus (CAdVEC) and T cells (HER2-AdVST). CAdVEC is an oncolytic adenovirus that has been modified to include additional immune system stimulators. Specifically, genes that stimulate the immune system have been added to the oncolytic adenovirus. Oncolytic adenoviruses are viruses that are made to target and kill cancer cells without killing normal cells. Other oncolytic adenoviruses have been used in patients before however CAdVEC has not. In this study, CAdVEC will be injected into participants tumor at one tumor site which is most easiest to reach. Once the oncolytic adenovirus infects the cancer cells, the genes will be expressed, resulting in activation of the immune response so it can attack and kill cancer cells. However, because this approach may have limited effects on the other tumor sites that have not received the oncolytic virus injection, 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 have found from previous research that investigators can put a new gene into T cells and make them specifically recognize and kill cancer cells expressing HER2. In the past patients have signed a consent form that allowed us to put on their T cells the HER2 chimeric receptor with viral antigen receptor on their T cells. Investigators want to see if these cells can survive in a patients blood and affect the tumor. Although HER2 chimeric antigen receptor modified cytotoxic T lymphocytes have been used in patients before, HER2-AdVST has not.
