Filter by:According to data from Global Cancer Statistics 2018, colorectal cancer (CRC) ranks second in incidence and fifth in mortality among all cancers in China. The underlying neoplastic progression from adenoma to CRC endures up to 10 years, providing an extended window for CRC detection and screening. Currently, fecal occult blood test (FOBT) and colonoscopy are the main diagnostic and screening methods for CRC in Chinese clinical practice. However, due to low patients' compliance with colonoscopy and poor sensitivity of FOBT, a large proportion of CRC could not be effectively diagnosed and treated at early stage. Therefore, noninvasive fecal DNA detection approach with enhanced performance is urgently needed in clinic. The aim of this trial is to evaluate effectiveness of the Human Multigene Methylation Detection Kit (Fluorescent PCR) for auxiliary diagnosis of colorectal cancer. By assessing the level of DNA methylation of certain genes in human stool, the test can indicate whether cancerous and precancerous lesions exist in the areas of colon and rectum.
The aim of this study was to evaluate the efficacy and safety of continuing cetuximab combined with chemotherapy after first-line progression in wild-type KRAS,NRAS and BRAF colorectal cancer.
Anastomotic leakage is serious morbidity that can develop in patients operated on for colorectal cancer and can reach potentially life-threatening dimensions. Many international studies have been conducted to reduce and eliminate this postoperative complication that may have a mortal course. In these studies, preoperative, perioperative and postoperative factors of the patient, operation techniques, structure of the material used in the operation and multiple factors belonging to the surgeon were held responsible. Intraabdominal sepsis secondary to late anastomotic leakage and subsequent multiorgan failure can cost the patient's life. Anastomotic leaks that develop in patients who have been operated for colorectal cancer; In order to detect patients' postoperative clinical findings, laboratory examinations, imaging tests, and to eliminate them before intraabdominal sepsis develops, studies including many different laboratory and imaging methods have been carried out. Although previous studies have shown that there are many laboratory examinations and imaging methods that can predict anastomotic leaks early, they have many advantages over each other in terms of efficiency, sensitivity, specificity, and cost. The investigators aimed to investigate the effectiveness of C reactive protein and blood sodium value, as well as their superiority, among the tests that can predict postoperative anastomotic leakage, especially in patients who have undergone a single anastomosis following resection for non-metastatic colorectal cancer.
A total of 138 consecutive patients who underwent laparoscopic-assisted or open colectomy for colorectal cancer (CRC) were included in the present study. Subjects commonly shared a condition of overweight or obesity. The investigators aimed to define any difference between the two different groups (open vs laparoscopic-assisted surgery) and a series of outcomes, i.e. hospitalization, Lymph nodes number, Intra-Surgery complications, and Clavien Dindo score.
Dr. Rogers' long-term goal is to better understand the etiology of an early-onset colorectal (CRC) diagnosis and to improve long-term survivorship and quality of life for early-onset CRC (EOCRC) survivors globally by studying the burdens accompanying this condition. The goal of this study is to better understand the reasons why people under age 50 in Utah and Wisconsin are being diagnosed with CRC. As a first step, the researchers identified the specific places in Utah and Wisconsin where diagnoses of CRC among younger people are increasing the most. Next, they conducted 1-hour recorded Zoom interviews over phone and/or video with 27 people across the United States diagnosed with CRC when they were under age 50. Thirdly, the researchers plan to create and test a program that will raise the awareness of residents in Utah and Wisconsin of the increasing risk of CRC among residents of the state who are aged under 50. This study is unique as CRC survivors are key to helping drive the study forward.
Aerobic exercise is associated with many benefits in patients with cancer treatments. Among these, the reduction of cancer-related fatigue (CRF) is one of the best demonstrated. Besides, several animal models have shown a marked reduction in tumor growth with aerobic exercise, sometimes by more than 60%. As the level of physical activity is convincingly associated with a reduction in the risk of cancer or recurrences, this suggests that aerobic exercise may represent a central therapeutic approach during treatment, both against CRF and for its potential anti-tumor effect. Both benefits have been suggested to be based on the immunostimulatory and anti-inflammatory effects of exercise. Indeed, systemic inflammatory activity seems to play a central role in the etiology of CRF during cancer treatments, among other things by stimulating the neuro-inflammatory activity of the central nervous system. Also, regarding the anti-tumor effect of exercise, animal models show that this benefit is partly explained by an increase in the activity of immune cells called natural killers (Natural Killer; NK) in tumor tissue and a reduction in the activity of regulatory T cells, the latter having an immunosuppressive effect. However, in humans, the results vary. While some improvement in NK cell activity has been reported in response to aerobic training in breast cancer survivors, others have seen no effect on the immune profile of patients and survivors. On the other hand, some authors report an improvement in the inflammatory profile with training, while others report little or no effect, as well as weak associations with the perception of fatigue. Although these results seem to discredit the hypothesis of immune and inflammatory regulation of exercise in humans, these studies have all looked at the effect of several weeks of training on the inflammatory and immune profile on an empty stomach and rest. However, several results from the field of exercise immunology convincingly show that the anti-inflammatory effect, as well as the immunostimulating effect of aerobic exercise (including the anti-tumor activity of NK cells) are mainly acute and transient, ie. in the hours following the end of the effort. Furthermore, certain results suggest that in the context of chemotherapy treatments, cyclical treatment by nature, the peaks of fatigue are also acute (i.e. in the days following the treatment) and parallel to peaks of inflammatory activity. Considering these results, it is therefore plausible to assume that the effect of aerobic exercise on suppressing tumor growth and reducing CRF results rather than the repetition of this acute response at each exercise session. In this case, the prescription of aerobic exercise preceding a session of chemotherapy could potentially represent an interesting therapeutic modality, allowing both the reduction of the CRF associated with this treatment, as well as a better response to the treatment. Besides, as this acute response seems to be highly dependent on the intensity of the effort, high-intensity interval training (HIIT) could be a particularly interesting approach in this context, because it does not require that the high intensity or long-lasting exercise. However, considering the immunosuppressive and pro-inflammatory effects of chemotherapy, the extent of the acute response to exercise may not allow this type of therapeutic use to be considered in this population. To date, no study has attempted to characterize the acute immune and inflammatory response following aerobic exercise in patients currently undergoing chemotherapy treatments.
This is a 3-arm randomized trial aimed at increasing rates of participation in colorectal cancer (CRC) screening by outreach to patients' homes using choice architecture informed by behavioral science principles.
The study is intended to compare the detection rate obtained by performing G-EYE® high definition colonoscopy vs. the detection rate obtained by performing ECV high definition colonoscopy.
The diagnostic accuracy and safety of colonoscopy highly depends on the quality of the pre-procedural bowel preparation. A past history of poor bowel preparation is the most important risk factor of inadequate bowel cleansing at the next colonoscopy. This study aims to evaluate if an adequate level of bowel cleansing can be achieved with the Pure-Vu System in patients with previous poor bowel preparation, in a single arm international multicenter feasibility study.
Immunonutrition (IN) appears to reduce infective complications and in-hospital length of stay (LOS) after gastrointestinal surgery. More specifically, it seems to be beneficial also in colorectal cancer surgery. Potential benefits of combining preoperative IN (PIN) with protocols of enhanced recovery after surgery (ERAS) in reducing LOS in laparoscopic surgery are yet to be determined.
