Filter by:The aim of this sudy is to investigate the prevalence of colorectal cancer (CRC) in patients with nonalcoholic fatty liver disease (NAFLD) and evaluate whether NAFLD is a risk factor for CRC.
To ensure the appropriate administration of Vectibix for the treatment of mCRC with wild-type KRAS in real-world practice, it is important to understand the awareness of practicing oncologists regarding the correct indication and appropriate administration of Vectibix. It is also critical to monitor changes in oncologists' awareness and practice between the different rounds of the study.
This open-label, randomized, multicenter, Phase 2 study will evaluate the safety and efficacy of MEHD7945A when combined with FOLFIRI (folinic acid [leucovorin], 5-fluorouracil [5-FU], and irinotecan) chemotherapy as compared to cetuximab plus FOLFIRI in participants with Kirsten Rat Sarcoma Viral Oncogene Homolog (KRAS) wild-type mCRC who have progressed after first-line oxaliplatin-containing chemotherapy for metastatic disease. Participants will be randomized to receive FOLFIRI chemotherapy plus either MEHD7945A or cetuximab. Anticipated time on study treatment is until disease progression or unacceptable toxicity occurs.
Aim of the study is to increase the proportion of indicated patients with colorectal cancer undergoing adjuvant chemotherapy following surgical resection through an optimized symptom management and logistical support.
RATIONALE: Computed tomographic colonography (CTC) has proven to be accurate in detecting colorectal neoplasms and may be a primary test in colorectal cancer screening. PURPOSE: This clinical trial will compare participation rate, diagnostic yield and costs of computed tomographic colonography, faecal occult blood test (FOBT) and colonoscopy (CO) as a primary screening test in a population-based programme.
The fluoropyrimidines 5-fluorouracil (5FU) and capecitabine (Cp) are among the most commonly used anticancer drugs. Still, there is much controversy about the correct dosing, and the fact that a minority of patients experience severe, sometimes even lethal toxicity following treatment. One important factor predisposing patients to severe toxicity is deficiency in the 5FU-catabolic enzyme dihydropyrimidine dehydrogenase (DPD). Our group identified 4 DPD risk alleles in over 300 Swiss cancer patients, that resulted in a 8-times increased risk of experiencing severe toxicity from 5FU or Cp. In patients receiving 5FU as a continuous infusion, there are accumulating data that keeping the AUC of 5FU between 20-30 mg*h/L is beneficial in terms of treatment toxicity and activity. In this study, patients carrying at least 1/4 DPD risk alleles will receive a 50% dose reduction of either 5FU or Cp, with the potential of later dose increases in the abscence of severe toxicity. Additionally, patients receiving i.v. 5FU will undergo therapeutic drug monitoring at the end of the 2-day continuous infusion, with subsequent dose adaptations to target a 5FU AUC of 20-30 mg*h/L. The primary study objective is to reduce the incidence of severe treatment-related toxicity from 13% (in historical controls) to 5% in study patients.
The purpose of this study is to test the efficacy of a collaborative care intervention to manage cancer-related symptoms and improve health related quality of life in patients diagnosed with hepatobiliary carcinoma.
The purpose of the study is to explore the influence of BRAF and PIK3K status on the efficacy of FOLFIRI plus Bevacizumab or Cetuximab, as first line therapy of patients with RAS wild-type metastatic colorectal carcinoma and < 3 circulating tumor cells
The purpose of the study is to evaluate FOLFOX + bevacizumab versus FOLFOXIRI + bevacizumab as first line treatment of patients with metastatic colorectal cancer not previously treated and with three or more circulating tumoral cells.
Colorectal cancer (CRC) is a leading cause of cancer death in the United States. Screening for CRC reduces CRC mortality, yet rates of screening in the United States remain low. Fecal occult blood testing (FOBT) has an established positive balance of benefit and risk, is the least expensive, and is the preferred method for nearly half of patients. A newer fecal screening test, the fecal immunochemical test (FIT), offers significant improvements over the FOBT. It is easier to use and is more sensitive at detecting both CRC and precancerous adenomas than the FOBT. The OC-Micro FIT is of particular interest because it is highly sensitive and specific and it is the only FIT test approved in the US that can be processed in an automated manner. Thus, the OC-Micro is an optimal method for use in mass screening programs to improve community CRC-screening rates. However, prior studies of OC-Micro suffer from several limitations: they were conducted in populations not optimal for assessing screening performance in average risk patients in the U.S. and the studies did not clearly establish optimal number of samples required and cut-points for test positivity. Therefore, the overall goal of MY-FIT is to capitalize on the highly integrated and extensive electronic medical record system of the study site to collect two separate sets of data that, when synthesized, will provide a thorough picture of the comparative patient adherence to, sensitivity, specificity, and costs of different protocols for using the OC-Micro FIT. Specifically, among KPNW members aged 50-75 who are at average risk for colorectal cancer (CRC) and who are due for CRC screening (n=78,000), the investigators propose to: 1. Compare the sensitivity, specificity, positive predictive value, and negative predictive value for colorectal cancer and advanced adenoma (advanced neoplasia) between a single-sample FIT (1-FIT) and a two-sample FIT (2-FIT) using varying cut points for a positive test (n=2100). 2. Compare patient adherence to completion of a 1-FIT versus a 2-FIT protocol (n=3000). 3. Assess and compare cost per screen for a 1-FIT versus a 2-FIT protocol, and the cost per advanced neoplasia detected in a 1-FIT versus a 2-FIT protocol (using varying cut points for a positive test) (n=78,000). Answering the above questions will provide a much-needed strong evidence base for a best-practice, cost-effective method of using the OC-Micro FIT to screen for CRC in a general U.S. population.
