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.
This is an single arm, open-label, phase II trial to evaluate safety and efficacy of using the combination of Camrelizumab with apatinib as second-line therapy for advanced PDAC.
Breast cancer incidence is increasing in low- and middle-income countries (LMICs) and breast cancer mortality is high in these regions largely due to late stage diagnoses. This is true in the low-income East African country of Rwanda, where there are no national protocols in place to guide evaluation and referral of breast symptoms at primary health facilities.
This study will use quantitative and qualitative methods to examine implementation of the Women's Cancer Early Detection Program (WCEDP) in order to understand optimal strategies to scale and sustain breast cancer early diagnosis in Rwanda and other limited-resource settings. The WCEDP is an adaptation of a prior intervention in Burera District, which focused on building community awareness of breast symptoms, improving clinicians' clinical breast assessment (CBA) skills, and implementing weekly breast clinics at the primary health care center and hospital levels. The Burera intervention was associated with improvements in health care workers' knowledge and skills, increases in care-seeking and receipt of care by women with breast symptoms, and an increase in early-stage breast cancer diagnoses.
RATIONALE: CI-1040 may stop the growth of tumors by blocking the enzymes necessary for cancer cell growth and by stopping blood flow to the tumor.
PURPOSE: Phase II trial to study the effectiveness of CI-1040 in treating patients who have metastatic or unresectable breast, colon, pancreatic, or non-small cell lung cancer.
This phase I trial studies the side effects and best dose of small interfering ribonucleic acid (siRNA)-transfected peripheral blood mononuclear cells APN401 (APN401) in treating patients with melanoma, kidney, or pancreatic cancer, or other solid tumors that have spread to other parts of the body or that cannot be removed by surgery. There are factors in immune cells in the blood that inhibit their ability to kill cancers. Treating white blood cells with one of these factors in the laboratory may help the white blood cells kill more cancer cells when they are put back in the body.
Creation of a collection of blood samples that will be collected before and then under treatment in patients with digestive adenocarcinoma during the 1st and 2nd metastatic line and which, depending on scientific progress, can be used for research projects aimed at developing tailored patient management strategies.
The investigators create organoid from the pancreatic cancer tissue obtained via EUS-FNA and EUS-FNB within the pancreatic cancer diagnostic process. And also the investigators create organoid from the pancreatic cancer tissue obtained after surgery as part of the pancreatic cancer treatment process. Check for the reactivity to anti-cancer drugs through cell viability assay after treating with various anti-cancer drugs, such as anti-cancer drugs used as adjuvant chemotherapy for pancreatic cancer to the organoid. Also, perform genomic analysis on each organoid, and then check if there are any unique genomic mutations for each organoid. By recognizing the relationship between the unique genomic mutations and reactivity to the anti-cancer drug within pancreatic cancer patients eligible for surgery, the investigators aim to strategize appropriate adjuvant chemotherapy after surgery, thus developing a platform to predict the outcomes of each patient.
Cystic lesions of the pancreas are defined as round, fluid-filled structures within the pancreas detected by radiologic imaging. With widespread use of cross-sectional imaging modalities for various indications, such lesions are now detected in nearly 20% of abdominal imagings, with the majority discovered incidentally. These lesions encompass a wide spectrum of histopathologic entities and biologic behavior, ranging from benign to malignant. Substantial morphologic overlap restricts the accuracy in diagnosing specific type of cystic lesion in spite of recent advances in diagnostic modalities. It is a challenging issue to differentiate each cystic lesion and make a management plan since cystic lesions that are relatively common and asymptomatic may possess malignant potential. Although inflammatory pseudocysts were thought to account for 80-90% of cystic lesions of the pancreas, with cystic tumors accounting for the remaining,10 the latter may occur much more frequently than traditionally estimated.
To date, surgical resection is generally recommended for malignant and potentially malignant lesions. However, surgical resection of the pancreas still carries substantial morbidity and sometimes mortality, especially for the cystic lesion located in the head portion. Therefore, management should be individualized by risk-benefit analysis for each patient.
Recently, a pilot study of EUS-guided ethanol lavage for cystic tumors of the pancreas reported that complete resolution was achieved in only one-third of patients even though epithelial lining ablation was demonstrated in all resected specimens. Therefore, more effective treatment modalities or ablation agents are required to improve treatment responses. Intratumoral or intraperitoneal injection of chemotherapeutic agent has been used for endobronchial lesions of lung cancer, brain tumors and advanced ovarian cancer.13-16 EUS-guided injection of antitumor material has been reported in advanced pancreatic cancer. Although local injection of chemotherapeutic agents into pancreatic cystic tumors has not yet been reported, it is reasonable to suggest that such an approach may have an additive effect on ablation of the epithelial lining of cystic tumor when combined with ethanol lavage.
Paclitaxel, a widely used chemotherapeutic agent, inhibits cell processes that are dependent on microtubule turnover. Due to its highly hydrophobic nature,19 paclitaxel is expected to exert its effect longer when instilled within a closed cavity such as a cyst. The hydrophobic and viscous nature of paclitaxel may reduce the possibility of it leaking through a puncture site and causing complications.
The present study evaluated safety, feasibility and response following EUS-guided ethanol lavage with paclitaxel injection (EUS-EP) for treating cystic tumors of the pancreas.
