Colorectal cancer (CRC) is the most common cancer for men and the second most common for women. Several studies have shown that gut microbiome may play a role in triggering intestinal inflammation that leads to the development of CRC. Gut microbiome is the collection of microorganisms that inhabit the gut. Therefore, manipulation of the gut microbiome via administration of probiotics may potentially improve the health and nutritional status in patients with CRC. The aims of this study are to investigate the role of probiotic functional foods in reducing CRC-related inflammatory markers and symptom alleviation.Participants will be needed to complete an information details form which includes information on age, medical history, background details and diet. Participants are required to consume the investigational product twice daily for six months. Blood samples will be collected prior to surgery and at 6th months post product consumption. These blood samples will be processed and analysed.
Colorectal cancer (CRC) is the third most common malignancy worldwide and is often metastatic at diagnosis. Despite progresses in surgical techniques and the introduction of novel chemotherapy regimens, many patients still suffer from a poor prognosis. It is therefore of utmost importance to identify prognostic markers that may improve selection of patients. In recent years several studies demonstrated that preoperative blood tests as platelet count or neuthophil-to-lymphocyte ratio could be prognostic factors in CRC as well as other malignancies. The aim of this study was to evaluate the role of preoperative platelet count (PC) in patients with synchronous colorectal liver metastases.
The survey is a retrospective study to evaluate the prognotic value of EGFR expression, KRAS mutations and tumor sideness in patients with metastatic colorectal cancer treated with regorafenib and FOLFIRI as a third- or fourth-line setting.
A randomized controlled trial to examine the effect of 3 mobile telephone text message reminders on followup colonoscopy 120 days after a positive fecal occult blood test among Meuhedet members aged 50-74 who tested positive in 2016.
This study compares flare type self-expandable metal stent with conventional D-type self-expandable metal stent for malignant colorectal obstruction.
Colorectal neoplasm in Asia is now increasingly common and is rising in an alarming manner in Hong Kong. Population-based screening for colorectal cancer (CRC) should be implemented. With the establishment of the CUHK JC Bowel Cancer Education Centre in 2008, about 10,000 asymptomatic subjects aged 50-70 years have completed screening by either faeca immunochemical test (FIT)or colonoscopy till December 2012. From 2013 onwards, the centre invites subjects aged 40-70 years with risk factors for CRC to undergo screening by FIT on a yearly basis. If FIT result is positive, according to local practice, they will be offered a routine colonoscopy as they will be treated as symptomatic. Currently, about 2,500 subjects have received CRC screening in this new project. There will be 2,500 subjects more to be recruited to this till 31 December 2017. The investigators would like to carry out a prospective cohort study of these 2,500 subjects and also retrospectively review the cohort of 12,500 subjects who received CRC screening in the CUHK JC Bowel Cancer Education Centre. The present study aims to: 1. . Evaluate the knowledge, attitude, perception, practice, perceived obstacles and changes in choice of CRC screening among the screening participants; 2. . Assess the levels of compliance across time among those who joined the screening programme, according to different subject characteristics; 3. . Explore the diagnostic accuracy of faecal immunochemical tests among subjects with different characteristics; 4. . Evaluate the risk factors for colorectal neoplasia and if applicable, devise and validate a risk scoring system for prediction of neoplasia in different colon sites; 5. . Evaluate the association between bowel preparation, colonoscopy withdrawal time and adenoma detection rate among those who received colonoscopy; 6. . Validation of the existing risk scoring systems for colorectal neoplasia from the literature, based on findings from subjects who received colonoscopy. 7. . Explore potential associations among colorectal neoplasia detected in different colon sites.
BACKGROUND: Colorectal cancer (CRC) and its treatment affect CRC survivors' quality of life (QoL), emotional distress and activities of daily living (ADL). It is assumed that occupational therapy interventions based on cancer education may be a feasible approach. Aim To examine the effect of using cancer education based on healthy lifestyle by occupational therapist on QoL, emotional distress, ADL and healthy lifestyle behaviors in CRC survivors. Methods Participants with CRC were designed as a two-group controlled trial, and a single-blind randomized controlled trial was conducted. These participants were randomly assigned to either an OT intervention or a non-intervention group (in a 1:1 ratio). Those participants in the OT intervention group were given a consultation based on a CRC education handbook by an occupational therapist for discharge preparation and on 1-month, 3-month follow-up clinic; the non-intervention group participants were given a CRC education handbook (the same handbook) only for discharge preparation. The primary outcome was the change in QoL measured using WHOOQOL-BREF. Secondary outcomes were changes in emotional distress, ADL and healthy lifestyle behaviors. Outcomes were examined in baseline (discharge preparation), 1-month and 3-months follow-up clinic.
Colon cancer with metastase in the diagnose time account for one significant rate and has a increasing trend. The treatment result of this patient group rests modest. The biological therapeutic treatment is still expensive for major part of Vietnamese patients. So that, research on a new affordable and efficacious chemotherapy combination for these patients is extremely necessary in our country The purpose of the study is to comment somes clinico-pathology features of metastatic colon cancer patients whose disease was not radically resectable. The second aim is to Evaluate the treatment result and toxicity of FOLFOXIRI in these patients
The study is based on the hypothesis that patients with postoperative anastomotic leakage have a different bacterial profile contributing to poor tissue healing, and that patients operated for colon cancer presumably have a different preoperative microbiota than healthy patients. This different composition is probably induced by the high heme level in the light intestinal tract that tumor spoliation generates. The objective of the study is to evaluate the feasibility of a larger study to evaluate the difference between microbiota composition of patients with and without colorectal cancer, with inflammatory bowel disease and those with and without anastomotic leakage postoperatively of a colonic resection. Stool samples will be taken from 20 patients, including 5 without intestinal pathology, 5 with colorectal cancer undergoing colorectal surgery, 5 with inflammatory bowel disease and 5 with anastomotic leakage after colectomy for colorectal cancer or inflammatory bowel disease. The stool samples will be analyzed at CRCHUM to draw up a profile of the bacteria that make up the microbiota of each patient.
Natural killer (NK) cells are leukocytes of the innate immune system and play a central role in the control of cancer metastases. NK cells and other innate immune cells often do not function well in patients with cancer and are also profoundly suppressed after cancer surgery. Dr. Auer's Lab and others have shown that NK cells are critically important in the clearance of tumor metastases and that their impairment can be recovered with immune therapy augmenting the innate immune system. Several studies suggest that cancer patients have depressed NK cell cytotoxicity as compared to healthy controls but that following resection of the cancer, NK cell cytotoxicity returns to normal levels. In this observational study, the investigators will measure NK cell cytotoxicity by the gold standard method (51Cr, a chromium51 release assay) and by a new interferon-ɣ (IFN-ɣ) based assay (NK-Vue™) in healthy humans and colorectal cancer (CRC) surgery patients seen a The Ottawa Hospital. The results of this study will determine if the NK-Vue™ is able to discriminate between healthy human volunteers and newly diagnosed cancer patients and is sufficiently sensitive to detect transient NK cell suppression immediately following surgery.
