Filter by:The aim of this study is to determine whether chemotherapy prior to tumor removal (neoadjuvant chemotherapy), in patients undergoing treatment for colon cancer in occlusion (CCO), would improve the rate of patients able to benefit from "optimal" treatment, i.e. complete treatment (including all neoadjuvant and adjuvant chemotherapy cures). This new strategy, which would combine chemotherapy before surgery and possibly post-operatively (depending on tumor analysis), could improve the prognosis of occluded colon cancers by treating circulating micrometastases and/or inducing a reduction in tumor size, thereby increasing the rate of complete resection.
Liver metastasis is the main reason that affects the survival rates of patients with colorectal cancer (CRLM), and is also the main cause of death of those patients. Especially after the failure of first-line or second-line system treatment, the prognosis of those patients is extremely poor, with the median OS of only 3.5 months. Even in combination with molecular targeted drugs such as cetuximab or bevacizumab, the median tumor-free survival period is only 4.8-6.8 months, and OS is only 11-15 months. When they have disease progression, treatment is currently a difficult clinical problem. Regofinib is a new targeted drug for the third-line treatment of advanced colorectal cancer in recent years. However, in the prospective multicenter clinical study, compared with the placebo group, the extended OS is only 1.4 months, which is not so satisfactory. How to improve the survival of these advanced patients with drug resistance is an important clinical problem to be solved urgently. Minimally invasive local treatment may be a promising way to solve this problem. Transcatheter arterial chemoembolization (TACE) and hepatic artery infusion chemotherapy (HAIC) are currently the most widely used methods in clinical practice. In theory, TACE combined with HAIC can control small metastasis and embolic residual lesions. The combination of TACE and HAIC can improve the curative effect. Whether the combination of TACE, HAIC and Regofinib can be expected to achieve the effect of 1+1+1>3 in CRLM patients who have failed the previous second-line chemotherapy remains unknown. Therefore, the purpose of this study is to explore the safety and clinical efficacy of irinotecan-loaded drug-eluting beads-TACE (DEBIRI-TACE) combined with HAIC and Regofinib in the treatment of patients with CRLM who failed standard treatment regimens.
In this protocol the investigators aim to overcome hepatic-pulmonary metastases-induced resistance to immunotherapy through high dose radiation therapy (SBRT) targeted to the metastases themselves, aiming, when possible, to ablate all macroscopic disease in these organs.
the 3-year randomized controlled RCT-SE study aims to investigate Socio-aesthetics well being care on quality of life, pain and anxiety. The primary objective is to show that socio-aesthetics well being care improves quality of life during cancer treatment, compared to self care administration of dermo-cosmetics products The secondary objectives are to show that socio-aesthetics well being care significantly reduced anxiety and pain compared to self care administration of dermo-cosmetics products
To learn if cemiplimab can help to control dMMR colon cancer.
Enhanced Recovery After Surgery (ERAS) protocols were developed to standardize perioperative practice in colon surgery to reduce morbidity, improve recovery, and shorten length of stay (LOS). Better protocol adherence translates into fewer readmissions and complications, and better 5-year survival. Preoperative elements, especially nutrition and immunonutrition, are topics that need further development to become the standard of care. It has been widely reported that the prevalence of malnutrition reaches 40% in cancer patients at the time of diagnosis. Impaired nutritional status at the time of surgery and cancer-induced inflammation, along with postoperative inflammatory responses to major surgery, increase the risk of postoperative complications, along with a decrease in perceived quality of life. Immunonutrition can modulate inflammation and reduce postoperative infections and shorten length of stay by counteracting the immune response induced by cancer. Adipose tissue has been shown to be a relevant source of inflammatory mediators, which may play a role in the promotion of tumor cachexia. The present study is a multicenter randomized control study (RCT) designed to evaluate the effect of preoperative immunonutrition in patients with colorectal cancer eligible for elective minimally invasive procedures, evaluating in particular surgical site infection and length of hospital stay. A biopsy of subcutaneous adipose tissue and visceral adipose tissue will also be performed, in order to evaluate the differences between inflammatory infiltrate, degree of fibrosis and cross-sectional area of adipocytes compared to controls.
This is an open-label Phase II trial that will investigate the use of neoadjuvant CAPEOX chemotherapy with Atezolizumab followed by surgery and adjuvant chemotherapy for patients with localized resectable pMMR adenocarcinoma of the colon with a target accrual of 30 patients. The investigators will explore if appropriately timed neoadjuvant CAPEOX with anti-PD-L1 mAb (Atezolizumab) can be administered safely and feasibly for 12 weeks, and that this combination will lead to improved clinical response associated with enhanced numbers of immune cells in surgically resected colon tumors. Participants will receive 4 cycles of atezolizumab in combination with 4 cycles of CAPEOX (atezolizumab will be administered prior to chemotherapy) before standard of care surgical resection. Each cycle of neoadjuvant therapy is 3 weeks. Following surgery, participants still considered to be at high-risk of recurrence (per NCCN guidelines) will receive further adjuvant chemotherapy (mFOLFOX6 or CAPEOX),for 6 and 4 cycles respectively (for a total of 12 weeks), based on the discretion of the treating oncologist/investigator. Participants will be followed up for an EFFICACY follow-up phase every 2 months during the first 6 months after surgery (months 1, 3, 6) and thereafter participants will enter a SURVIVAL follow-up phase and will be seen every 6 months starting at month 12 until month 36. During this the efficacy and survival follow up visits blood samples will be obtained for purposes of obtaining circulating DNA and stool and optional blood samples for storage for future exploratory analysis. Additionally, during these follow up visits, participants will be asked to complete quality of life questionnaires
It is estimated that about 20% of colonoscopies have inadequate preparation. (5) This is associated with lengthy procedures and less detection of adenomas, reduces the screening intervals, and increases the costs and risks of complications. Several strategies have been proposed to improve the quality of bowel preparation. Mobile healthcare Apps have been developed to increase adherence to bowel preparation agents, improving the quality of bowel preparation. However, adherence to mobile healthcare Apps is also a quality criterion and a pending problem to solve with this new technology. GastroBot is a new technology based on artificial intelligence that allows, through a software bot, to carry out a personalized follow-up of the patient's bowel cleansing, advising the patient to overcome contingencies that arise with the preparation, which in other circumstances could lead to the failure of it. The primary aim of this study is to determine the improvement in bowel preparation after GastroBot assistance compared with the traditional explanation. As a secondary aim, this study also pursues to determine adenoma and polyp detection rates (ADR and PDR, respectively), bowel preparation agents' tolerance, and GastroBot functionality.
The aim of this study is to evaluate the safety and efficacy of neoadjuvant immunotherapy combined with chemotherapy before colonic resection in patients with locally advanced colon cancers
The goal of this observational study is to determine whether the secreted protein QSOX1 can be used as a molecular marker for early rapid diagnosis and accurate treatment of colon cancer.
