In the light of literature data, it becomes crucial to develop models for studying the functionality of CTCs. In this context, xenograft models in nude mice have recently been described9,10. Establishing cell lines to allow CTC amplification to have enough material to work is an attractive approach.
Background Cancer cell development requires a series of acquired capabilities to grow and spread: 1) self-sufficiency in growth signals, 2) insensitivity to growth inhibition signals, 3) evasion of apoptosis (programmed cell death), 4) limitless replicative potential, 5) sustained angiogenesis and
TACE is indicated for the treatment of unresectable CRC_LM, patients who are refractory to systemic chemotherapy, elderly, or have a poor performance status, and is usually performed using irinotecan (IRI) covalently loaded onto embolics.
Although chemoembolization with irinotecan-loaded embolics
Patients that have been scheduled for colonoscopy will undergo chart review. Patients who meet inclusion criteria will be invited to participate at the time consent is obtained for the colonoscopy. Participants will then be randomized to one of two colonoscopy starting positions.
After
Objective: We study the efficacy of the retractor sponge in laparoscopic colorectal surgery to reduce hospital stay in patients operated for a malignancy. Secondary objectives are duration of surgery, blood-loss, use of diuretics as volume therapy (during surgery as wells as during total hospital
Colonoscopy has become an essential part of the patient management, especially in the field of colorectal cancer prevention. About 15 million colonoscopies were done in the United States in 2012. Data from United States and European countries suggest that the majority of investigations are performed
Nowadays, more and more attention are paid to system biology and its relative techniques, such as gene sequencing,nuclear magnetic resonance, mass spectrometry and so on. As a newly developed subject, metabolomics can detect accurately and quantitatively small molecule metabolites such as proteins,
1. Sample size calculation, randomization and patients safety. The required sample size is calculated from previous studies on the incidence of postoperative pulmonary complications. A two group chi-square test with a 0.05 two-sided significance level will have 80% power to detect the difference (in
Up to 30-40% of patients operated from colorectal cancer display tumor recurrence. Predictive biomarkers are needed to identify those patients with higher risk of recurrence. Our main objective is to determine a metabolite profile in blood plasma from patients operated from colorectal cancer that
It is estimated that 234.2 million major surgical procedures are undertaken every year worldwide. Surgery is one of the major treatment methods for patients with malignant tumor. And, alone with the ageing process, more and more elderly patients undergo surgery for malignant tumor. However, evidence
Colorectal cancer (CRC) is one of the leading causes of cancer mortality in Canada. Rectal cancers are now known to be hypoxic which is a negative prognostic factor and predictive of metastatic spread and poor responsiveness to treatment. This has also been shown in preclinical xenograft models.
Rationale: Non-invasive imaging of hypoxia with the aid of PET-scans could help to select the patients having a hypoxic tumor, who could be treated with specific anti-hypoxic treatments. The added value of additional anti-hypoxic treatments depends on the presence of hypoxia and adequate patient
Group 1. Inclusion: 200 patients with colorectal cancer scheduled for surgery and 200 controls. Due to drop outs we calculate a need of inviting at least 250 patients with colorectal cancer. We will use controls from an ongoing epidemiological study of sleep apnea in the population.
Exclusion:
Intrahepatic cholangiocarcinoma (IHC) are cancers with pathologic features of biliary tract differentiation which arise from intrahepatic bile ducts and/or trans-differentiation of hepatocytes. IHC is the second most common primary liver cancer and its incidence and mortality rates are increasing
