A cardiopulmonary exercise test (CPET) is increasingly used for preoperative risk assessment. Oxygen uptake (VO2) at peak exercise (VO2peak) and VO2 at the ventilatory anaerobic threshold (VO2VAT) are the most commonly used preoperative CPET variables that are associated with postoperative outcomes following colorectal cancer surgery. The aim of this study is to investigate the association between two relatively new preoperative submaximal and effort-independent CPET variables, the cardiopulmonary optimal point (COP) and the Oxyen uptake efficiency plateau (OUEP) and postoperative outcomes in colorectal cancer surgery. In additiion, the association between the oxygen uptake at the COP en OUEP and postoperative outcomes wil be explored.
For patients with initially unresectable colorectal liver metastasis (IU-CRLM) receiving effective conversion therapy, disease relapse after conversion hepatectomy is common due to the extensive tumor load. Yet, few studies have focused on the assessment and management of relapse after conversion hepatectomy for IU-CRLM. This study aimed to investigate the impact of surgical management for relapse after conversion hepatectomy in IU-CRLM.
Colorectal cancer (CRC) is the second most commonly occurring cancer worldwide. Thirty-five percent of CRC patients are diagnosed at stage II/III, and their outcome differs even if they are in the same stage. Previous study found that the microenvironmental collagen is associated with tumor progression and metastasis. Whether tumor microenvironmental collagen signature is associated with colorectal cancer prognosis still remains unknown. We hypothesize that the tumor microenvironmental collagen signature of colorectal cancer is associated with prognosis.
Immunotherapy improved efficacy and survival in selective patients with metastatic colorectal cancer (mCRC), however, limited data revealed the landscape of immunotherapy efficacy. What's more, potential markers have not been comprehensively evaluated to identify responding patients to further improve efficacy.The investigators conducted a single-arm study to investigate the efficacy of combination immunotherapy in patients with mCRC, and the combined regimen is determined by the physician in charge.
The purpose of this study is to retrospectively analyze colorectal cancer screening data of 40-74 year old population in Shipai Town, Dongguan City. In this study, the data of SDC2 Gene Methylation Test and Fecal Immunochemistry Test (Q-FIT) were screened from about 11,000 subjects who participated in Colorectal Cancer Screening in Shipai Town People's Livelihood Project from May 2021 to May 2022. Data from 822 subjects with positive SDC2 Gene Methylation Test and/or positive Fecal Immunochemistry Test (Q-FIT) results and with colonoscopy and/or pathological results were selected for retrospective analysis. This retrospective study evaluated the screening performance of SDC2 Gene Methylation Test and/or Fecal Immunochemistry Test (Q-FIT) for colorectal cancer using colonoscopy and/or pathological results as the clinical standard method.
The aim of this study was to compare the effects of expiratory muscle training (EMT) and incentive spirometry (IS) in addition to conventional pulmonary rehabilitation after colorectal surgery. Twenty-four individuals (13 male) undergoing colorectal surgery were included. They were randomly divided into two groups. In addition to conventional chest physiotherapy, group 1 was performed EMT (n=12), group 2 was performed deep breathing exercises with incentive spirometry (IS) in postoperative period. Respiratory muscle strength, functional capacity, levels of movement and independence, and postoperative pulmonary complications (PPC) were evaluated. Length of stay in hospital (LOS) was recorded.
Nimotuzumab is an IgG1 humanized monoclonal antibody that recognized an epitope located in the extra cellular domain of the human epidermal growth factor receptor (EGFR). Clinical efficacy has been shown in adult with head and neck cancer. The study assessed the safety, and efficacy of the combination of Nimotuzumab administered concomitantly with chemotherapy in patients with advanced colorectal cancer.
This study was designed to investigate the efficacy of flow cytometry to accurately identify between normal and cancer cells in colon epithelium in humans diagnosed with colorectal cancer.
To test the applicability of the Clavien-Dindo Classification (CDC) in an LMIC setting and to compare the prevalence and severity of complications in patients <60 and ≥60 years of age a retrospective medical records review is used.
A clinical trial to assess the efficacy, mechanism of action and safety of the Colovac+ Colorectal Anastomosis Protection Device in providing temporary protection of the anastomosis in subjects undergoing lower anterior resection for colorectal cancer
