Filter by:Malnutrition priori a major abdominal surgery is frequent and increases morbidity and mortality. The management of malnutrition has an impact in reducing postoperative complications. However malnutrition is rarely detected and Guidelines infrequently followed. Recovery time and nutritional evaluation in elderly patients are major criteria in their postoperative management. Identifying malnutrition or malnutrition risk is fundamental to its treatment. It is therefore unsurprising that many validated tools for nutrition risk screening and nutrition assessment exist for the clinician to use in assisting with the accurate identification, referral and treatment of patients who are malnourished or at risk of malnutrition. And nutritional management must be adapted and based on this evaluation and evolution of the general status (Guidelines Grade A). A geriatric evaluation based on a screening of preoperative malnutrition should allow a better implementation of the European Society of Parenteral and Enteral Nutrition (ESPEN) guidelines.
The aim of this study is to identify biomarkers of disease recurrence and prognosis to optimize patient selection for treatment with cytoreductive surgery (CRS) with hyperthermic intraperitoneal chemotherapy (HIPEC), and through animal models to explore different treatment strategies for peritoneal surface malignancies (PSM).
1. To evaluate efficacy, safety, and feasibility of maintenance therapy with Cetuximab combined with irinotecan or fluorouracil after Cetuximab plus irinotecan and fluorouracil(FOLFIRI) in patients with incurable colorectal cancer. 2. The relevant phase III studies reported that the progression free-survival of cetuximab combined with FOLFIRI in advanced colorectal cancer was 4.3 months up to 6.8 months. This study assumed that the progression free-survival was 5.1 months which was not inferior to the continuous chemotherapy
Survival after colorectal cancer (CRC) diagnosis strongly depends on local tumor extent, lymph node involvement and the presence of distant metastases. However, there remains great inter-patient variability regarding treatment outcome. A combination of biochemical factors, histopathological features, genomic profile, environmental factors and other clinical factors are likely to influence prognosis and treatment effect, independent from tumor stage, but it is still unclear which, how, and to what extent these factors can influence tumor recurrence and mortality in both early stage (I-III) and late stage (IV) CRC, small bowel cancer and anal cancer. Although the results from prospective clinical trials will remain the backbone of evidence based medicine, this concerns a highly selected patient population since the large majority (85%-95%) of cancer patients do not participate in clinical trials for various reasons. It is unlikely that trial participation will significantly improve in the near future. This fact has the following implications: 1) It is highly desirable to validate the results from trials in the general patient population. However, this is complicated by the fact that the documentation of patients treated in general practice (i.e. outside the scope of clinical trials) is largely insufficient to provide comparable patient cohorts in terms of prognostic characteristics and treatment parameters. 2) There is an increased availability of novel technologies that provide molecular markers with potential prognostic and/or predictive value. To test the clinical value of these markers large numbers of patients are required which greatly exceeds the number of patients who consent to participate in prospective clinical trials. 3) as a result of rapid technical developments, a range of new minimally invasive treatment options are entering the market. These interventions have the potential to be of great benefit for patients in terms of improved local control, higher probability of complete tumor removal, less damage to surrounding tissue, faster recovery and less short and long term side effects. Still, the interventions will have to prove their effectiveness, safety and superiority (or non-inferiority) to standard cancer treatments on a patient level. A prospective observational cohort study has the great opportunity to fill this gap.
The purpose of this study is to evaluate the efficacy and safety of recombinant anti-tumor and anti-virus protein for injection plus capecitabine in treating patients with metastatic colorectal cancer who have progressed after standard therapy.
Folic acid (FA) and its derivatives (folate) which play a role in nucleotide synthesis and methylation reactions as well as calcium and vitamin D are assumed to be effective in the prevention of colorectal polyps and Colorectal cancer (CRC). The aim of this study is to investigate the roles of FA as well as calcium and vitamin D in the prevention of CRC.
This is a phase I/II multi-center open-label proof of concept study, consisting of two parts. Part A of this study is designed to identify the recommended phase 2 dose (RP2D) of the combination regimen of dacomitinib plus PD-0325901 in patients with advanced KRAS mutant (KRASm) non-small cell lung cancer (NSCLC). Part B is designed to perform a randomized comparison of the combination of dacomitinib and PD-0325901 versus standard of care therapy in patients with advanced KRASm NSCLC. It is hypothesized that with this combination strategy the progression free survival of patients with KRASm NSCLC will be doubled.
The morbidity of colorectal cancer(CRC) is 10%～15% in China.mFolfox6 has become one of the standard regimes for metastatic colorectal cancer (mCRC). Neutropenia and oxaliplatin-induced neurotoxicity are the most common adverse effects which even result in discontinue of chemotherapy, especially for patients suffered from heavily acute neurotoxicity. Monosialotetrahexosylganglioside is a component of membrane of nerve cells. Previous phase II clinical trial showed, it can reduce oxaliplatin-induced neurotoxicity(OIN). But it did not certificated by phase III trial. Investigators designed the phase III trial to investigate the effect and safety of monosialotetrahexosylganglioside Sodium Injection for prevention OIN at colorectal cancer.
The purpose of this study is to assess whether the use of I-Scan during colonoscopy leads to an increased yield of adenomas in the colon among a population at increased risk for CRC. Primary Outcome: Adenoma Detection Rate (ADR — No. of colonoscopies at which one or more histologically confirmed adenomas were found divided by the total no. of colonoscopies performed in the same time period) in the right colon using High Definition White Light Colonoscopy Versus I-Scan enhanced Colonoscopy. Secondary Outcomes: - Adenoma Detection Rate (ADR) of High Definition White Light Colonoscopy Versus I-Scan colonoscopy through out the entire colon. - Adenoma Detection Rate (ADR) in the right colon during the "Second look", irrespective of imaging modality. - Polyp Detection Rate (PDR - No. of colonoscopies at which one or more polyps were found(regardless of the histological type) divided by the total no. of colonoscopies performed in the Same time period) for each arm of the study in Right colon and throughout the entire colon. - Mean number of adenomas per procedure for each arm of the study in right colon and throughout the entire colon. - Mean number of polyps per procedure for each arm of the study in right colon and throughout the entire colon. - Number of neoplastic lesions for each arm of the study in the right colon and throughout the entire colon and number of neoplastic lesions missed on 1st pass of right colon. - Proportion of patients with diminutive lesions (< 5 mm) in each arm of the study - Proportion of patients with Flat lesions (height < 1/2 diameter) in each arm of the study - Proportion of patients with Sessile Serrated Adenoma in each arm of the study - Proportion of patients with invasive cancer in each arm of the study - Presence or absence of learning effect while using this technology given that use of I-Scan may train the human eye to better identify adenomas even without image enhancement.
The purpose of this study is to investigate the invasive front in growth mode (expanding or infiltrative) and dedifferentiation (tumor budding) and comparing these with the tumor surface (polypose or flat) + / - ulceration in surgical specimens at colorectal cancer.
