Filter by:Investigating the efficacy of Cetuximab Monotherapy versus Continuation after induction treatment with chemotherapy + Cetuximab in inoperable or irresectable and non-progressive metastatic colorectal cancer after first line induction treatment for 24 weeks with mFOLFOX6/FOLFIRI and Cetuximab treatment. Reinduction treatment will be done in case of progression.
This study is try to evaluate the effect of cetuximab monotherapy as maintenance treatment, versus continuation after 8 courses of induction therapy with cetuximab plus standard chemotherapy regimen (FOLFIRI or mFOLFOX6）in metastatic colorectal cancer (mCRC) patients. The maintenance treatments are continued until disease progression or untolerated toxicity. The aim of this study is to demonstrate that cetuximab monotherapy is non-inferior to continuation treatment, in those mCRC patients who responded to induction therapy(SD, PR, or CR), and carry biomarker-panels (KRAS, NRAS, BRAF, and PIK3CA) favor EGFR antibody.
Colorectal cancer is the third most common cancer diagnosed in both men and women in the United States. The death rate from this disease, however, has been decreasing over the last 20 years. Early detection and removal of pre-malignant polyps is considered to be at the core of this change. At the same time, polyp detection is highly dependent on an adequate bowel preparation. Froehlich, et al., found that poor bowel preparation is associated with longer colonoscopy times, more difficult procedures and a higher rate of incomplete procedures(2). Although a Clear Liquid Diet is usually the prescribed diet in most bowel preparation regimes, several studies have shown similar results with less restrictive diets. Based on the hypothesis that a Full Liquid Diet(FLD) is not inferior to a Clear Liquid Diet(CLD), investigators plan to conduct a prospective, randomized trial, in order to compare these dietary interventions. The investigators and endoscopists will be blinded to patient's diet group. Researchers aim to investigate if diet liberalization to a Full Liquid Diet(FLD) is associated with similar bowel cleansing as compared with a Clear Liquid Diet(CLD). Investigators will compare the performance of these dietary interventions regarding adenoma detection rates(ADR), time to cecal intubation(TCI), and colonoscope withdrawal time. In addition, the investigators want to assess whether patient's Compliance and Satisfaction is similar or superior in the experimental group vs the control group.
Recent pre-clinical data provide strong evidence that short-term starvation before the administration of cytostatic drugs for the chemotherapy of solid tumors leads to significantly higher efficacy and lower toxicity levels. However, these findings have so far not been validated in patients. The aim of this trial is to provide first clinical evidence regarding the impact of pre-chemotherapeutic short-term starvation on response to therapy (primary endpoint). Additionally, progression-free survival, adverse events, and overall survival will be monitored (secondary endpoints). In perspective, short-term starvation before chemotherapy could represent a simple and secure way to improve both efficacy and tolerance of chemotherapies at low cost.
This study is to verify the advantage of FOLFOXIRI plus cetuximab over FOLFOXIRI plus bevacizumab as the first-line therapy in metastatic colorectal cancer patients with RAS wild-type tumors.
Stage III colorectal cancer constitutes more than half of the colorectal patients, and the prognosis does not improve much recently although varies of adjuvant drugs have been tried. DC-CIK immunotherapy has been proved to improve survival in cancer patients, but its role in stage III colorectal cancer patients stains unclear. The investigators study will focus on the efficacy and safety of DC-CIK immunotherapy plus chemotherapy in the adjuvant treatment of stage III colorectal cancer, compared with chemotherapy alone.
It is unknown whether post operative chewing gum will reduce post operative ileus. This study is a randomised controlled trial that will determine whether chewing gum three times a day following surgery will reduce post operative ileus. Time to passage of flatus will be used to determine that incidence of ileus.
The primary objective of this study is to correlate the percentage change in apparent diffusion coefficient (ADC) between baseline and early therapy (at day 14) with tumor regression grade (TRG) measured in the surgical resection specimen.
Anesthesia favouring deep/intense neuromuscular blockade during laparoscopy may restore hemodynamics. However, no studies has been performed comparing oxygenation parameters during laparoscopy in colorectal surgery in either moderate or intense neuromuscular blockade. The investigators aim to investigate whether the intense neuromuscular blockade produces a better oxygenation profile measured by the central venous oxygen saturation than the moderate neuromuscular blockade. This is a one centre, prospective clinical trial to compare oxygenation data at different stages of neuromuscular blockade in high-risk patients scheduled for colorectal surgery. Data recording will be blinded to the anesthesiologist in charge of the patient, who will manage patients by a determined protocol, based on stroke volume data to direct fluidotherapy. Data analyzer will be not be involved in the study design or in writing reports from the study. Inclusion criteria: Be a candidate to a colorectal surgical resection procedure and one of these conditions: ≥ 70 y.o, or respiratory co-morbidity, or cardiac co-morbidity or haemoglobin level < 11g/dl. The primary outcome is the absolute number of the central venous oxygen saturation, measured at the following points: basal, after tracheal intubation, before pneumoperitoneum or abdominal incision, after pneumoperitoneum or abdominal incision, 5 and 10 minutes before administration of rocuronio to produce intense blockade, continuously during profound neuromuscular blockade until the end of surgery, before sugammadex administration, after sugammadex administration, after tracheal extubation, for the 24 hours post surgical. Data of the regional cerebral oxygen saturation will be measured at the same points. The investigators hypothesize that oxygenation data will be favourable by applying the intense neuromuscular blockade in comparison with moderate neuromuscular blockade. Also, the investigators hypothesize that oxygenation data obtained during the whole procedure including the first 24-hours post-surgery, measured by the regional cerebral oxygen saturation are comparable to data obtained by the central venous oxygen saturation. The investigators want to obtain information about influence in the outcome of producing profound neuromuscular blockade during laparoscopy colorectal by comparison of outcome data with matched historical control.
The purpose of this study is to determine whether dietary nitrate supplementation improves performance in cardiopulmonary exercise testing (CPET).
