Filter by:Irinotecan and raltitrexed are active against advanced colorectal cancer (ACC), act through different mechanisms, and have only partially overlapping toxicity profiles. The purpose of this study is to evaluate efficacy and safety of irinotecan plus raltitrexed as second-line treatment in advanced colorectal cancer patients.
Background: Combinations of Dendritic and Cytokine-induced Killer Cells (DC-CIK) and Cytokine-induced Killer Cells (CIK) treatment may enhance the immune response and stop cancer cells from growing. The investigators suppose that DC-CIK combined with CIK treatment will improve the prognosis of advanced solid tumors. Objective: Phase II clinical trial to investigate the efficacy of concurrent chemotherapy with DC-CIK and CIK treatment in patients with treatment-refractory solid tumors. Study treatment: Patients in group A will receive 4 cycles of CIK treatments and 4 cycles of DC-CIK treatments within 8 months. Patients in group B will have no immunotherapy . chemotherapy are available in both groups.
This randomized clinical trial studies how well neomycin and metronidazole hydrochloride with or without polyethylene glycol work in reducing infection in patients undergoing elective colorectal surgery. Polyethylene glycol, may draw water from the body into the colon, flushing out the contents of the colon. Antibiotics, like neomycin and metronidazole hydrochloride, may stop bacteria from growing. It is not yet known whether it's better to give preoperative neomycin and metronidazole hydrochloride with or without polyethylene glycol in reducing surgical site infection after colorectal surgery.
The purpose of the study is to see how measurements of tumor differences vary with slight changes in CT scan parameters. Reproducible radiomic features can be extracted for abdominal tumors, and specifically colorectal liver metastases, imaged with clinical CT scanners even in the setting of variable scan parameters and variable contrast timing. Participants will be consented to undergo an additional CT of their abdomen.
A single-central,open-label,safety,pharmacokinetics,phase I study. Biological:Recombinant Anti-EGFr Antibody Two dose levels: Low-dose level patients received initial dose 100 mg/m2 and 4 weeks later 250 mg/m2 weekly maintenance to the disease progression or unacceptable toxicity or death or withdraw informed consent.High-dose level patients received cetuximab initial dose 400 mg/m2 and 4 weeks later loading 400 mg/m2 and 250 mg/m2 weekly maintenance to the disease progression or unacceptable toxicity or death or withdraw informed consent.
Worldwide, nearly 1.25 million patients are diagnosed with and more than 600,000 patients die from colorectal cancer each year. The third leading cause of death is colorectal cancer in Taiwan 2012. The current treatments for colorectal cancer including surgery, chemotherapy and/or radiotherapy are prescribed to improve survival and lower the risk of recurrence. However, disease and treatment-related toxicities in cancer patients may result in fatigue and interfered quality of life (QoL). Previous studies have reported that cancer-related fatigue (CRF) is the most common symptom experienced by patients at all stage of diseases, it can occur during treatment, in advanced disease and in disease-free survivors; the prevalence of fatigue is reported to be between 59-96% in patients undergoing chemotherapy, 65-100% in patients receiving radiation therapy, and 30% in long term survivors. Also, CRF has been reported as the most frequent and distressing toxicity of colon and rectal chemotherapy. The National Comprehensive Cancer Network (NCCN) has published guidelines for the definition of CRF as ''a persistent subjective sense of physical, emotional, and/or cognitive tiredness or exhaustion related to cancer or cancer treatment that is not proportional to recent activity and that significantly interferes with usual functioning." Besides, CRF could dynamically change with the interactions among disease progression, treatment regimen, tumor site, nutrition, infection or other factors. Therefore, to minimize the impact of CRF on cancer patients, more in-depth researches on CRF are needed. The aim of this longitudinal study is to examine the dynamic changes, correlated factors and QoL of CRF among colorectal cancer patients during adjuvant chemotherapy. Furthermore, the results will supply physicians with more understanding about CRF, and help them to enhance the quality on cancer care to being perfected in the future.
Despite the growing public awareness and recent progress in multimodality therapy to the colorectal cancer (CRC), CRC still ranks high on the list of the most common and deadly cancers in Taiwan. The cause of CRC mortality is due mainly to the occurrence of distant metastasis. Several reports suggested that circulating tumor cells (CTCs) highly associated with metastasis suggesting that targeting CTCs may offer an unprecedented opportunity to prevent the development of metastasis. Early detection and characterization of CTCs is therefore important as a potential strategy to monitor the progression of CRC. The current proposal is focused on detecting CTCs from peripheral blood of CRC patients using Miselect R system. We will monitor the amount of CTCs and correlate with CRC progression and prognosis.
Microsatellite instability is more common in colorectal cancer ( CRC) young patient which is associated with good prognosis and is considered as a predictor for good response to preoperative chemoradiotherapy. Counting of ( cluster of differentiation) CD 133 +ve cells ,as a marker for enrichment with colorectal cancer stem cells ,is considered as a prognostic marker for poor survival and predictor for radio-resistance. Correlation between microsatellite status ( MS) and CD133 count has not yet studied especially in young patients with rectosigmoid cancer. So the investigators hypothesize that there is correlation between microsatellite status, CD133+ve cells count , occurrence of CRC in young patients and resistance to standard treatment regimen. Improvement of response to treatment and choice of the best regime to avoid non beneficial treatment modality are the goal of this study.
Patients with histologically proven adenocarcinoma of the rectum will receive pelvic radiotherapy to a dose of 45Gy in 25 fractions with a tumor boost to a dose of 9Gy in 5 fractions (thus total of 54Gy/30Fx to the primary tumor), combined with radio sensitizing chemotherapy. Patients will then be closely monitored, through endoscopy and imaging, for response to treatment and relapse. Salvage oncologic surgery to be offered if there is failure to achieve complete clinical response or in the event of a loco regional relapse.
This 4-week prospective double blind anaemia management study evaluates the effect of high-dose postoperative intravenous iron vs placebo for patients after colorectal cancer surgery. Patients with preoperative levels of haemoglobin 90-120 g/l will be randomly assigned to receive either 1 g of intravenous iron or equal amount of saline postoperatively. Comparison will be based on the levels of haemoglobin, ferritin and other haematological parameters over time and profile of clinical recovery. The primary end point is that iron isomaltoside given postoperatively is superior to placebo in terms of increase and stability of levels of haemoglobin and other haematological parameters.
