Filter by:This is a phase 2 pragmatic study that evaluates the clinical benefit of continuing systemic therapy with the addition of locally ablative therapies for oligo-progressive solid tumors as the primary objective. The primary outcome measure is the time to treatment failure (defined as time to change in systemic failure or permanent discontinuation of therapy) following locally ablative therapy.
The study is a real-world observational clinical study. Patients diagnosed as colorectal cancer through histopathology were screened and enrolled. Before anti-tumor treatment, colonoscopy biopsy tissue specimens, surgical specimens, and malignant pleural effusion or ascites specimens, etc. are collected. The investigators will perform a drug sensitivity testing based on a novel drug susceptibility testing method to test the commonly used anti-tumor treatment regimens. Patients were given conventional anti-tumor treatment according to the medical judgment of the doctors. Finally, the investigator will evaluate the consistency of clinical efficacy in colorectal cancer treatment and drug susceptibility outcomes.
dMMR/MSI-H colorectal cancer patients are the dominant population of immunotherapy/neoadjuvant immunotherapy, but imaging evaluation of immunotherapy efficacy is insufficient. There are some cases, although no disease remission was found on imaging,pathological complete response (pCR) was confirmed after surgery. Meanwhile,previous studies have shown that dynamic changes in ctDNA can help assess immunotherapy efficacy. Therefore, we propose to conduct a multicenter, prospective, observational clinical study to explore the efficacy prediction and monitoring value of ctDNA in immunotherapy for advanced or locally advanced dMMR/MSI-H colorectal cancer.
The primary aim of this study is to collect and store data, tissue, and personal and family histories from patients being screened for colorectal cancer and/or endometrial cancer at NYPH and WCM for routine clinical care and to make these available for future use for molecular and mechanistic studies.
This study assesses the feasibility and acceptability of a brief electronic patient-reported outcome (ePRO) tool that allows patients to self-identify impending delays. The risk of treatment delays according to tumor type and race will be measured by both ePRO and electronic health record (EHR) tools. Data from this study and the association of social determinants of health could be useful to flag patients at risk of delay and due timely intervention for modifiable treatment barriers. The prediction of the risk of treatment delay will be helpful to design another study using electronic tracking systems to prevent cancer treatment delays. The long-term goal of this research is to alert care teams when patients may be at risk of treatment days and to help patients get treatment faster. It was planned to enroll a total of 240 subjects with newly diagnosed cancer. Sixty colorectal and 180 breast cancer patients will be included.
This is a study in adults from Asia with different types of advanced cancer (solid tumours). People can join the study if they have cancer of the stomach, large bowel and rectum, pancreas, liver, head and neck or non-small cell lung cancer. This is a study for people for whom previous treatment was not successful or no treatment exists. People can participate if their tumour has the B7-H6 marker. The purpose of this study is to find the highest dose of BI 765049 that people with advanced cancer can tolerate when taken (alone and) together with ezabenlimab. Another purpose is to check whether BI 765049 taken (alone and) together with ezabenlimab can make tumours shrink. Both medicines may help the immune system fight cancer. Participants can stay in the study up to 3 years, as long as they can tolerate it and can benefit from it. During this time, they visit the study site about every 3 weeks. At the study site they get BI 765049 alone or in combination with ezabenlimab as an infusion into a vein. BI 765049 is given in 3-week cycles, ezabenlimab is given once every 3 weeks. The doctors check the health of the participants and note any health problems that could have been caused by BI 765049 or ezabenlimab. Doctors regularly check the size of the tumour and check whether it has spread to other parts of the body.
Approximately two-thirds of all colorectal cancer patients undergo surgery with the aim of curing them. However, despite the surgery, 20-25% of them experience relapse. It is possible to reduce the risk of relapse with chemotherapy, but as chemotherapy is associated with significant side effects, it is only given to patients at high risk of relapse. Currently, the risk is assessed based on an examination of the removed tumor tissue. In a previous research project, blood samples were taken after patients' surgery and examined for the presence of circulating tumor DNA (ctDNA). When cancer cells in solid tumors die, they release DNA, which can be detected in the blood. DNA in the blood has a half-life of less than 2 hours, so if ctDNA is found in a blood sample taken, e.g., 14 days after surgery, the patient most likely still has cancer cells in their body. The results show that if a patient has ctDNA in their blood after surgery, the risk of relapse is high. The presence of ctDNA in the blood has the potential to be a better indicator of the risk of future relapse than the tumor examination used today. Therefore, ctDNA analysis has the potential to become a marker that will be used in the future clinical setting for monitoring colorectal cancer. The overall objective of this study is to confirm that ctDNA found in a blood sample after intended curative treatment for CRC is a marker of residual disease and risk of recurrence and is applicable in clinical practice.
The intrinsic connection between inflammation and tumor promotion is well characterized and is a key pathogenic event in patients with colorectal cancer (CRC), the second most common cause of tumor-related death in western countries. Environmental factors and chronic inflammation represent the major causes of intestinal carcinogenesis. In fact, patients suffering from inflammatory bowel diseases, including Crohn's disease and Ulcerative Colitis (UC), have high risk of developing colitis-associated CRC with poor prognoses. Therefore, targeting the cancer-associated inflammation may offer new avenues for cancer treatment. In fact, several anti-inflammatory drugs, have been used for prophylaxis and have shown efficacy in contrasting cancer, despite various adverse side effects. Thus, there is an urgent need to discover novel cancer-associated mechanisms to develop alternative therapies that may reduce aberrant inflammatory responses without interfering with physiological defenses against infection and functional anti-tumor immunity. A novel approach promoting anti-tumor immunity has been recently proposed after the discovery of potent, endogenous, specialized pro-resolving mediators (SPMs), including lipoxins, resolvins, protectins, and maresins, mainly derived from omega-3 polyunsaturated fatty acid (PUFA) docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) via COX, LOX and CYP450 pathways, mediated by MFSD2A. Due to the potent bioactivity of SPMs in resolving inflammation and because of the correlation between inflammation and cancer, the roles of these lipid mediators have attracted great attention for their potential therapeutic role in cancer treatment, including CRC. Nevertheless, the understanding of the endogenous mechanisms that limit the inflammatory response during CRC development is incomplete and requires further investigation. Based on the preliminary results indicating that dysfunctional MFSD2A-dependent pro-resolving pathways may foster CRC development, the investigators aim to define the functional role of MFSD2A in orchestrating pro-resolving pathways in the intestinal endothelium of metastatic and not metastatic CRC patients. This is a cross-sectional single-center observational study involving patients with CRC. The investigators will enroll 15 patients with colorectal cancer (CRC) stratified by tumor stage (T0 / T1-T4, M0 / M1, N0 / N1 / N2) undergoing surgery in the Gastroenterology and Digestive Endoscopy unit within Gastro Center (IRCCS Ospedale San Raffaele). Human Intestinal Microvascular Endothelial Cells (HIMEC) will be generated from each sample of cancer surgical specimens, while the healthy cells will be derived from the healthy margins of the colorectal resection of the same CRC patients. MFSD2A will be overexpressed or silenced and the investigators will evaluate its biological effects in both tumor-derived HIMECs and healthy tissue-derived HIMECs through transcriptomics and lipidomics analysis. The investigators will also exploit a possible novel therapy based on the delivery of MFSD2A encoding plasmid-conjugated liposomes.
