Filter by:Complete and timely colonoscopy after an abnormal stool-based colorectal cancer screening test results in early detection, cancer prevention, and reduction in mortality, but follow-up in safety-net health systems occurs in less than 50% at 6 months. The proposal will implement multi-level approach consisting of a stepped-wedge clinic-level intervention of team-based best practices co-developed with primary and specialty care, a patient-level technology intervention to provide enhanced instructions and navigation to complete diagnostic colonoscopy, and a mixed methods evaluation to explore multi-level factors contributing to intervention outcomes. Developing a solution to this high-risk and diverse population has the potential to translate to other health systems, support patient self-management, and address other patient conditions.
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.
Hypoxia represents the prevailing adverse occurrence during the sedation of patients undergoing gastrointestinal endoscopy with propofol. A recent innovation in this domain is the COMBO Endoscopy Oropharyngeal Airway-a multifaceted device that encompasses capnography monitoring, bite block , oxygenation support, and oropharyngeal airway management. This device has been purposefully designed to cater to the unique requirements of endoscopic procedures. The principal objective of our randomized study is to assess the efficacy and safety of the COMBO Endoscopy Oropharyngeal Airway reduce the incidence of hypoxia on patients undergoing gastrointestinal endoscopy under propofol sedation.
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.

Contrarily to late-onset (LO) colorectal cancer (CRC), early-onset (EO) CRC incidence is increasingly growing. Several factors, such as obesity, chronic inflammation, and intestinal dysbiosis, can increase the general risk of CRC. However, little is known about the biology of EO-CRC. To evaluate whether such selective rise in the incidence of EO-CRC patients mirrors a distinct transcriptomic profile, the investigators will first dissect EO-CRC's transcriptomic landscape. Then, the investigators will investigate the colorectal cancer stem cell (CSC) compartment by in vitro functional assays and RNA-seq analysis. Because our preliminary data indicate an increased aggressiveness of the tumor microenvironment (TME) in EO-CRC,the investigators propose to investigate the CSC niche and the interaction with the TME to dissect the molecular and cellular pathways occurring in EO-CRC. A cohort of 30 EO-CRC patients (<50 years old) will be enrolled and fully characterized. About 10 EO-CRC-derived CSCs in the form of organoids and spheroids will be generated. Since the relevant differences between CR-CSCs isolated from EO-CRC vs LO-CRC patients are still unknown, the investigators will gain information about their specific features such as clonogenic activity, tumorigenic/invasive capacity, and about differences in the mechanisms regulating their cross-talk with TME components.
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.
OBJECTIVE: To evaluate the effectiveness of a PET scan in oncological patients, with and without simultaneous treatment with chemotherapy, radiotherapy or hormonal therapy, in improving quality of life and the need for supervision by health professionals during its performance after 6 weeks of intervention. DESIGN: Randomized controlled clinical trial, parallel groups with active control group. With randomization blinding, patient assessment and data analysis. STUDY SUBJECTS: 78 patients diagnosed with breast and colon cancer and treated up to 2 years later, both with surgery, chemotherapy and hormonal treatments (aromatase inhibitors, tamoxifen). INTERVENTION: three treatment groups: supervised therapeutic exercise group without supervised therapeutic exercise group without chemotherapy, radiotherapy or hormonal treatment, supervised therapeutic exercise group with simultaneous chemotherapy, radiotherapy or hormonal treatment and control group. Two groups will be supervised in performing PET for a period of 6 weeks and the other group will do it autonomously and unsupervised. Patients will be followed for 1 year, with five blinded assessments: at baseline, after 6 weeks of intervention, 3, 6 and 12 months after baseline. MEASUREMENTS: Main: Quality of life assessed with questionnaire measured with the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire C-30 (EORTC QLQ-30). Measured pre-post intervention, 3, 6 and 12 months. Secondary: Cancer-related fatigue assessed with the Functional Assessment of scale Chronic Illness Therapy - Fatigue (FACIT-F). Measured pre-post intervention, 3, 6 and 12 months. Functional capacity measured with the 6-minute walk test. Pre-post intervention measurement, 3, 6 and 12 months. Strength assessment measured with manual hydraulic dynamometer and 5 repetitions of the sit-to-stand test. Pre-post intervention measurement, 3, 6 and 12 months.
CROSCO-1 study is a national, multi-center, prospective observational study presenting patients to the emergency departments of the participating centers with obstructive left colon cancer (in the absence of metastases and peritoneal carcinomatosis) undergoing primary surgical tumor resection with a primary colorectal anastomosis (associated or not with a diverting loop ileostomy) or without a primary anastomosis ("Hartmann's procedure") or staged resection after endoscopic stenting with Self-expandable Metallic Stent (SEMS). The main questions it aims to answer are: - the Stoma rate at 1 year after tumor resection - the 30-day and 90-day major morbidity and mortality - 1-year quality of life (EQ-5D-5L test) - Timing of chemotherapy initiation and type of chemotherapy regimen. Participants will have an obstructive left colon cancer localized (no peritoneal carcinosis or distant metastasis). Researchers will compare: primary surgical tumor resection with a primary colorectal anastomosis (associated or not with a diverting loop ileostomy) or an "Hartmann's procedure" with a staged resection after endoscopic stenting with SEMS.
