This is an open-label, single centre, single-arm phase II study which aims to assess the efficacy and tolerability of triplet combination of capecitabine, oxaliplatin and irinotecan (Xeloxiri regimen) in treating patients with refractory metastatic colorectal cancer. Clinical data from patients diagnosed with colorectal cancer will be collected and analyzed in this study. The patients' data will be collected and maintained in the Division of medical oncology of the Department of Medicine, Queen Mary Hospital.
In liver surgery peroperative assessment och the future liver remnant (FLR) is pivotal in order to avoid posthepatectomy liver failure. To date this is mainly performed by measuring the volume of the FLR. Of course FLR volume acts as a surrogate measure of FLR function and the correlation between volume and function is not always accurate. Several techniques to assess FLR function has been proposed. Hepatobiliary scintigraphy (HBS) and Dynamic MRI are the two such methods. In this study we compare HBS and MRI, in addition to contrast-enhanced CT and ICG, repeatedly performed before and after right hepatectomy in patients with colorectal liver metastases treated with neoadjuvant chemotherapy.
This study is a randomized phase II trial to evaluate the efficacy of adjuvant consolidative radiotherapy in colorectal cancer liver metastasis (CRLM) patients after chemotherapy combined with surgical resection or radiofrequency ablation of liver lesions.
This is an observational study to assess the determinants of energy expenditure in cancer, and how those change throughout the disease trajectory. The investigators hypothesize that skeletal muscle will be the primary determinant of energy expenditure throughout the disease trajectory.
Patients with resectable liver metastases of colorectal origin will be assigned to laparoscopic liver resection or conventional open liver surgery. Blood samples will be drawn preoperatively and 24 hours after resection. Determination of Interleukin-6 (IL-6) and IL-8 will be done to assess the stress response between open and laparoscopic liver resection (Elisa test). The Messenger Ribonucleic Acid (mRNA) of inflammation related factors (cyclooxygenase-2 (COX-2) and Matrix metalloproteinase (MMP-9)), angiogenesis related factor (vascular endothelial growth factor (VEGF) and hypoxia induced factor-1 (HIF-1)) in tumor tissue and normal liver parenchyma will be detected by real-time real time-Polymerase Chain Reaction (RT-PCR).
To date no prospective trials have been completed that demonstrated whether RFA is an effective adjunct to systemic chemotherapy (target therapy) with respect to advantages in overall survival compared with chemotherapy (target therapy) alone. The primary objective of this trial is to determine overall survival for patients with colorectal cancer liver metastasis are treated with radiofrequency ablation plus chemotherapy ± target therapy, compared to chemotherapy ± target therapy only.
This study is aimed to evaluate the safety of applying enhanced recovery after surgery for colorectal cancer.
It is estimated that there are about 1.4 million patients with colorectal cancer (CRC) worldwide, with a rising trend in CRC incidence in many Asian Pacific countries. In Hong Kong, colorectal cancer ranks first in cancer incidence and second in cancer mortality based on data from 2013. CRC is one of the most preventable cancers because its development in general follows an adenoma-carcinoma sequence. Adenomas are considered precursor lesions for CRC. While early detection and removal of colorectal adenoma by screening colonoscopy with polypectomy reduce CRC incidence and mortality, interval cancers (cancers that develop after a colonoscopy and before the next scheduled colonoscopy) may still occur and were reported to account for up to 10.5% of CRC. The protective effect of colonoscopy against cancer in the right colon has not been consistently demonstrated. Interval CRC has been associated with proximal colon location, small lesion, flat lesion, missed lesion, inadequate examination, incomplete resection of lesion, tumor biology, and low adenoma detection rate (ADR). High ADR (eg, ≥ 20%) has been associated with a reduced risk of interval CRC. Methods that can improve polyp detection in the right colon such as retroflexed examination of the right colon, second forward view examination of the right colon, use of colonic fold flattening device, colonoscope with an increased field of view may potentially reduce the risk of interval CRC, but data is still limited. Performance of a second forward view (SFV) examination of the right colon may be the easiest and safest from a practical standpoint when compared to other options (eg, additional training is often needed for retroflexed examination of the right colon since there may be a potentially higher risk of perforation in endoscopists not familiar with the technique, additional equipment is needed when using a colonic fold flattening device, or a colonoscope with an increased field of view). Our current study aims to determine whether a routine SFV examination in the right colon can lead to an increase in adenoma / polyp detection when compared to conventional withdrawal examination in the right colon in both male and female patients undergoing screening and surveillance colonoscopies.
The main study objective is to determine the feasibility and impact (effectiveness) of intervention models for lifestyle changing (diet and physical activity) on health outcomes. Women 50 to 54-year-old attending the local breast cancer screening and 58-year-old people (both sexes) undergoing colorectal cancer screening are invited to participate in the study. Compliers are randomized into 3 intervention groups (Diet, Physical Activity, and Physical Activity and Diet) and into the 'usual care' Control group. Biological sampling (blood and saliva) is collected from all participants. All participants undergo also anthropometric measurements and fill in a self-administered validated questionnaire on their dietary and physical activity habits. All enrolled subjects receive a booklet with basic information about diet and physical activity. Subjects randomized to the 3 intervention groups are also offered one theoretical and three training courses. The courses are specifically designed for the different interventions proposed and aimed at reinforcing the educational counseling and at supporting behavioral changes. Follow-up is performed at 8 (intermediate follow-up) and 12-14 (final follow-up) months for repeating anthropometric measurements and questionnaire filling and blood sampling (at the final one).
