Colorectal cancers account for 783,000 new cases and cause 437,000 deaths per year across the world. Diagnosis in the early stages improves survival rates. Up to now, these cancers are mostly diagnosed only at later stages of the disease's course through histoimmune staining and molecular biology processes on the tissues biopsied from the gastrointestinal system under invasive diagnostic procedures of colonoscopy.
Oral fluid presents a large protein complexity and has been recently used as a diagnostic biofluid for oral, as well as systematic diseases. Using oral fluid as a bio-marker for the colorectal cancer can be advantageous as it contains gastrointestinal fluids, in addition to bacteria and bacteria lysate, which can also serve as a bio-markers' source for colorectal cancers. Proteomic technologies provide the tools needed to discover and identify disease-associated biomarkers.
The aim of the present study is to identify salivary bio-markers in patients suffering from colorectal cancers.
This is a single arm study to evaluate the efficacy and safety of CEA-targeted CAR-T cells therapy for patients with relapsed/refractory CEA+ Cancer,and obtain the recommended dose and infusion plan.
This study is a non-randomized, open-label, multi-cohort, multi-site, pilot feasibility therapeutic trial. The study will enroll 20 patients across 4 cohorts (CRC, gastric, PDAC, and HCC/intra-hepatic-/extra-hepatic-, gall bladder adenocarcinomas) diagnosed with histologically confirmed GI cancers. These patients will have already completed all Standard of Care (SOC) treatments (including neoadjuvant, surgery, local therapies, and/or adjuvant therapy as applicable), as defined by the treating primary physician or research team, with curative intent but have a positive SignateraTM tumor-informed ctDNA test and NED radiographically by standard imaging within 28 days prior to enrollment and within 1 year of completing all curative-intent therapy. All patients will be treated with intravenous (IV) atezolizumab 1200 mg IV and bevacizumab 15 mg/kg on Day 1 of 21-day cycles until disease recurrence, ctDNA POD, unacceptable toxicity, or subject withdrawal of consent with a maximum 12 month total duration of study therapy. Atezolizumab and bevacizumab drug will be provided.
The question being asked in this study is: Will patients with advanced pancreatic cancer live significantly longer if they are treated with a combination of Gemcitabine and ON 01910.Na than if they are treated with Gemcitabine alone? There are two parts to this study. In the first part of the study, patients with metastatic pancreatic cancer who have received no prior chemotherapy for this disease will be assigned by chance either to the group that will be treated with both Gemcitabine and ON 01910.Na (about 100 patients will be in this group) or, to the group that will be treated with Gemcitabine only (about 50 patients will be in this group). How long patients survive in the 2 groups will be compared. If it looks like there is no difference between the groups, the study will stop. If it looks like patients in the group that were treated with both Gemcitabine and ON 01910.Na survive longer, the study will continue into a second part where more patients will be treated in order to confirm and better understand the findings of the first part of the study.
Contrast enhanced harmonic Endoscopic Ultrasound (CH-EUS) can be used during a conventional EUS examination to correctly identify and target lesions with the help of Ultrasound Contrast Agents. When CH-EUS is applied to the dynamic ultrasound images of conventional EUS, additional information about tumour vascularity can be obtained solely from the visual uptake of contrast agent into the tumour. Angiogenesis within malignant tumour tissue is varied from that of its normal surrounding tissue.Blood flow within malignant tissue is characteristically low volume. Contrast agents are slow to pass through tumour microvasculature and hence this is seen as an area of hypo-enhancement. This hypo-enhancement or hypo-vascularity is well demonstrated in PDAC and the opposite is known to be true for PNET, both of these findings showing to be consistent with cytopathological results.Tumour hemodynamics and vascular patterns resultant from contrast uptake can be analysed further with the help of fractal use. Attaining this information can allow more accurate characterization of both PDAC and PNET thus in turn predicting their respective behaviours i.e., aggressiveness (local or systemic spread) and histological grade.

Contrast-enhanced computer tomography (CT) is currently used to evaluate the response of chemotherapy in patients with PDAC according to the RECIST guidelines. However, one significant advantage of CH-EUS over dynamic CT imaging is that ultrasound contrast agents do not leak into the interstitial space allowing for better quantitative measurement of tissue perfusion.More recently, the EFSUMB guidelines have recommended dynamic CH-EUS as a preferred technique to monitor anti-angiogenic treatment.This founds the basis for evaluating CH-EUS's role. *(with the help of fractal analysis)-remove this if needed* in predicting PDAC's response to neo-adjuvant chemotherapy as this is yet to be evaluated.
Yamashita et al. demonstrated that patients with PDAC with positive vessel sign showed a significantly longer progression free survival compared with patients with negative vessel sign after chemotherapy (P = 0.037; log-rank test).
EUS elastography (EUS-E) is a US technique that measures the hardness of tissues. The level of hardness of SPLs can be evaluated using qualitative scores and/or quantitative methods (strain ratio [SR]).
This is a prospective, open-label therapeutic interventional investigation designed to interrogate the efficacy and safety of individualized matched therapies in patients with pancreatic cancer at high risk of disease recurrence post-surgery.
The study is a multi-center, open-label, randomized active controlled study of subjects with locally advanced pancreatic adenocarcinoma which is unresectable.
Venous catheters are necessary for the treatment of many patients. Showering with a venous catheter is often prohibited due to the infection risk when the insertion site becomes wet. Therefore these patients are challenged to keep the catheter insertion site dry and always covered with a dressing. Washing themselves is often impossible without assistance of a nurse or significant other. For patients with a catheter connected to an infusion line, it is even more difficult. Showerpatch is a newly developed dressing that safeguards the insertion site of an IV catheter from water during bathing activities. The purpose of this trial is to evaluate the impact of the availability of Showerpatch by comparing the outcomes in patients regarding the patient's autonomy in bathing activities, the material use and the time needed from caregivers in home care. Additionally qualitative data on patient's bathing activities and the use of Showerpatch will be collected.
This phase II trial tests whether treosulfan, fludarabine, and rabbit antithymocyte globulin (rATG) work when given before a blood or bone marrow transplant (conditioning regimen) to cause fewer complications for patients with bone marrow failure diseases. Chemotherapy drugs, such as treosulfan, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Fludarabine may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. rATG is used to decrease the body's immune response and may improve bone marrow function and increase blood cell counts. Adding treosulfan to a conditioning regimen with fludarabine and rATG may result in patients having less severe complications after a blood or bone marrow transplant.
The aim of this observational study is to comprehensively analyze the metabolites in plasma samples from multi-cancer patients using advanced mass spectrometry detection technology, in conjunction with metabolomics approaches. The goal is to construct a plasma metabolite database for multi-cancer patients. Simultaneously, we will delve into the exploration and validation of a series of metabolic biomarkers for early multi-cancer diagnosis. The objective is to establish a safer, more convenient, and more sensitive early screening method, thereby providing a reliable scientific foundation and critical evidence for improving the early diagnostic process for individuals at high risk of multi-cancer.
