NCT ID: NCT03782428 Completed - Colorectal Cancer Clinical Trials

An Evaluation of Probiotic in the Clinical Course of Patients With Colorectal Cancer

Start date: August 26, 2016
Phase: N/A
Study type: Interventional

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.

NCT ID: NCT03717519 Completed - Colorectal Cancer Clinical Trials

Elevated Platelet Count as Prognostic Factor in Colorectal Cancer With Synchronous Liver Metastases

Start date: January 1, 2018
Study type: Observational

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.

NCT ID: NCT03698253 Completed - Colorectal Cancer Clinical Trials

Metastatic Colorectal Cancer Treated With Regorafenib and FOLFIRI

Start date: October 1, 2013
Phase: N/A
Study type: Interventional

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.

NCT ID: NCT03642652 Completed - Colorectal Cancer Clinical Trials

SMS Reminders for Positive FOBT Follow-up

Start date: April 1, 2016
Phase: N/A
Study type: Interventional

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.

NCT ID: NCT03640572 Completed - Colorectal Cancer Clinical Trials

Disseminated Tumour Cells (DTC) in Left Sided Colorectal Cancer (LSCC).

Start date: June 1, 2007
Study type: Observational

Two metaanalyses of studies on the prognostic significance of circulating cancer cells in colorectal cancer indicated, that the presence of circulating tumour cells (CTC) in the peripheral blood is the negative prognostic factor. However there is no sufficient evidence that disseminated tumour cells (DTC) in the bone marrow of the colorectal cancer patients influence the prognosis. There is the evidence that right-sided and left- sided cancers may have different biology and different prognosis. Therefore in this study the investigators concentrated on the left colon and rectum locations with the locally advanced cancer being the main area of interest. The aim of this study was to analyse the relation of DTC with the tumor characteristics, cancer progression and survival in left sided colorectal cancer.

NCT ID: NCT03602417 Completed - Colorectal Cancer Clinical Trials

Flare Type Self-expandable Metal Stent for Malignant Colorectal Obstruction

Start date: January 1, 2017
Phase: N/A
Study type: Interventional

This study compares flare type self-expandable metal stent with conventional D-type self-expandable metal stent for malignant colorectal obstruction.

NCT ID: NCT03597204 Completed - Colorectal Cancer Clinical Trials

CRC Screening for High Risk Population in HK

Start date: October 7, 2015
Phase: N/A
Study type: Interventional

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.

NCT ID: NCT03521765 Completed - Colorectal Cancer Clinical Trials

Quality of Life in Colorectal Cancer Survivors

Start date: July 1, 2017
Phase: N/A
Study type: Interventional

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.
