FOS Immunohistochemical Staining of Colorectal Cancer and Its Adjacent Tissues

Start date: December 1, 2020
Phase: Phase 2/Phase 3
Study type: Interventional

Colorectal cancer tissue sections were obtained according to the inclusion criteria. The formalin was used to immersed all cancer specimens. And tissues were cut to 5 μm thickness and placed on glass slides before staining. Endogenous peroxidase activity was inhibited and blocked by de-paraffinizing, rehydrating, and using 5% bovine serum albumin at 37ºC for 30 min. The treated sections were incubated with anti-FOS (promab 30360) at 4ºC overnight and washed three times with PBS. After that, it is required that incubation with secondary anti-peroxidation sunflower at 37ºC for 30 minutes. After washing three times again with PBS, the sections were developed in diaminobenzidine and microscopic images were made by light microscopy.

PRospective rEgistry OF Advanced Stage cancER (PREFER) Patients to Assess Prevalence of Actionable Biomarkers and Driver Mutations to Address Disparities in Precision Medicine

PREFER
Start date: April 19, 2021
Phase:
Study type: Observational [Patient Registry]

The objective of this Study is to collect, process, and transfer biologic samples such as blood and/or tissue biopsies to determine the concordance of detected alterations obtained through liquid biopsy analyses compared to next generation sequencing of time-matched or archival tissue specimens from individuals with advanced solid tumors. Examples of locally advanced and metastatic tumors include stage III and IV cancers (ex. lung, breast, all gastrointestinal malignancies, all gynecologic malignancies, prostate cancer, head and neck tumors, soft tissue cancers, and melanoma). These specimens will be analyzed for diagnostic purposes and research (either by Labcorp/OmniSeq or to a third-party recipient designated by Labcorp/OmniSeq). Labcorp/OmniSeq may transfer the specimens and data to its clients, including commercial, academic or non-profit research institutions; or alternatively, may retain the specimens in its repository for future research use at the sole discretion of Labcorp/OmniSeq and or assignees. Labcorp/OmniSeq will maintain all detailed clinical information including demographic data (de-identified), ethnicity, disease state, stage (radiological, pathological and clinical-whichever is relevant).

A Study of NUC-3373 in Combination With Other Agents in Patients With Colorectal Cancer

Start date: January 2023
Phase: Phase 2
Study type: Interventional

This is a randomized, open-label, dose/schedule optimization study comparing NUC-3373/leucovorin (LV)/irinotecan plus bevacizumab (NUFIRI-bev) to 5-FU/LV/irinotecan plus bevacizumab (FOLFIRI-bev) for the treatment of patients with unresectable metastatic colorectal cancer. A total of 171 patients will be randomized 1:1:1 to either NUFIRI-bev on a weekly NUC-3373 schedule, NUFIRI-bev based on an alternate weekly NUC-3373 schedule, or FOLFIRI bev on an alternate weekly schedule. The main objectives are to assess and compare the efficacy and safety of the 3 regimens. Pharmacokinetics will be assessed on the 2 NUFIRI arms.

Clinical Study on the Efficacy of Autologous Cell Factor Induced Killer Cells in the Treatment of Colorectal Cancer

Start date: January 9, 2023
Phase: N/A
Study type: Interventional

This project plans to use CIK combined with chemotherapy, immunotherapy and targeted therapy to treat CRC patients, so as to explore the effectiveness of CIK treatment and the CRC subtypes more suitable for CIK treatment, thereby improving the survival rate and quality of life of CRC patients.

NCT ID: NCT05663788 Recruiting - Colorectal Cancer Clinical Trials

Web-based Learning Module on Optical Diagnosis of Early Colorectal Cancer

LODIP
Start date: July 1, 2022
Phase: N/A
Study type: Interventional

International guidelines recommend deciding the treatment of colorectal lesions based on the estimated histology by endoscopic optical diagnosis. However, the theoretical and practical knowledge on optical diagnosis is not widely expanded The mail goal of this randomised controlled trial is to compare the pooled sensitivity of optical diagnosis for predicting deep submucosal invasion in large non-pedunculated polyps > 20 mm assessed in routine colonoscopies of gastroenterologists attending a e-learning module (intervention group) vs gastroenterologists who do not (control group) The main questions the study aims to answer are: - Is the pooled sensitivity of optical diagnosis for predicting deep submucosal invasion in large non-pedunculated polyps assessed in routine colonoscopies increased in those gastroenterologists participating in the e-learning module? - Is the pooled diagnostic accuracy of optical diagnosis for predicting deep sm invasion in large non-pedunculated polyps ≥ 20 mm assessed in routine colonoscopies increased in those gastroenterologists participating in the e-learning module? - In lesions with submucosal invasion, is the en bloc and complete resection rate (R0) increased in those gastroenterologists participating in the e-learning module? - In lesions referred to surgery, is the pooled benign polyps rate decreased in those gastroenterologists participating in the e-learning module? - In lesions treated with advanced en bloc procedures (ESD, TAMIS, fullthickness resection), is the pooled rate of histology with high-grade dysplasia, intramucosal cancer or submucosal invasion increased in those gastroenterologists participating in the e-learning module? - In lesions treated with piecemeal endoscopic resection, is the pooled rate of histology with high-grade dysplasia, intramucosal cancer or submucosal invasion decreased in those gastroenterologists participating in the e-learning module? - Is the diagnostic accuracy for predicting deep submucosal invasion in a test with pictures increased after participating in the e-learning module? The participants (or subjects of study) are gastroenterologists. They will be randomised to do the e-learning course (intervention group) or not (control group). Researchers will compare clinical outcomes of gastroenterologists participating in the e-learning module vs gastroenterologists not participating in the e-learning module to see if: - the pooled sensitivity of optical diagnosis for predicting deep submucosal invasion in large non-pedunculated polyps > 20 mm assessed in routine colonoscopies is increased. - the pooled diagnostic accuracy of optical diagnosis for predicting deep sm invasion in large non-pedunculated polyps > 20 mm is increased. - the en bloc and complete resection rate (R0) is increased in lesions with submucosal invasion. - the pooled benign polyps rate decreased in lesions referred to surgery. - the pooled rate of histology with high-grade dysplasia, intramucosal cancer or submucosal invasion increased in lesions treated with advanced en bloc procedures (ESD, TAMIS, fullthickness resection). - the pooled rate of histology with high-grade dysplasia, intramucosal cancer or submucosal invasion decreased in lesions treated with piecemeal endoscopic resection. - the diagnostic accuracy for predicting deep submucosal invasion in a test with pictures after participating is increased.

NCT ID: NCT05646030 Recruiting - Colorectal Cancer Clinical Trials

Feasibility, Reliability, and Satisfaction of CEA Using Home Based (Automated) Capillary Blood Sampling

CASA-I
Start date: March 25, 2022
Phase: N/A
Study type: Interventional

The goal of this study is to determine the feasibility of CEA assessments at home using (automated) capillary sampling in patients in the follow-up after treatment for colorectal cancer. The main questions it aims to answer are: - To determine the success rate of capillary sampling at home by the patient - To assess reliability and satisfaction of (automated) capillary CEA measurements Participants will be asked to perform automated capillary sampling and lancet capillary sampling at home twice after regular check-up visits in the hospital, with an interval of 3-6 months in between. During this hospital visit, a CEA measurement in blood sampled by venipuncture will be performed to act as a reference for the CEA measurements in (automated) capillary blood to be sampled at home. Reliability of CEA measurements will be assessed for automated capillary and lancet capillary sampling compared to venipuncture. Satisfaction in terms of patient reported outcomes (pain, burden, ease of use, and preference) will be evaluated.
