Filter by:This observational, multicenter, prospective study will evaluate the use of bevacizumab in real clinical practice in chinese patients with metastatic colorectal cancer.
To analyze the pathological tumor response on resected colorectal cancer metastases after preoperative treatment with cetuximab combined with FOLFOX or FOLFIRI regimen in a prospective cohort (RAS and B-RAF WT tumors) and to correlate this response with patient's outcome.
The study is designed to analyze the pathological tumor response on resected colorectal cancer metastases after preoperative treatment with bevacizumab combined with FOLFOX or FOLFIRI regimen in a prospective cohort and to correlate this response with patient's outcome.
This study is to assess the efficacy and safety of Endostar combined with mFOLFOX6 in untreated metastatic colorectal cancer patients, and to find the markers that may predict the efficacy.
To determine the objective overall response of re-treatment with cetuximab-based chemotherapy in patients upon disease progression while under observation, who had previously responded to first-line or second-line treatment with cetuximab-based chemotherapy for metastatic colorectal cancer (mCRC), but had stopped treatment for reasons other than disease progression.
Investigators propose to assess, retrospectively (from 1/7/2009) and prospectively (up to 31/12/2013,) the safety and tolerability profile (number of participants with adverse events) of standard chemotherapy and anti-angiogenic agent bevacizumab (Avastin) as first line treatment of patients with metastatic Colorectal Cancer with or without KRAS mutation. All treatment schedules that are going to be assessed are considered by the international guidelines as standard therapy for patients with metastatic Colorectal Cancer.
The treatment of the most common cancers (colon, breast, lung, liver and kidney) has recently added a new therapeutic class known as the "anti-angiogenic". It was born from a better understanding of tumor growth requires the development of neo-vessels. These new vessels are of major importance for the viability of the tumor but also the birth of metastases. This neo-angiogenesis is complex and results from an imbalance between pro-angiogenic factors and anti-angiogenic factors. Growth factor VEGF and its receptors (VEGFR-1, VEGFR-2 and VEGFR-3) are a way of survival of endothelial cells required for tumor neoangiogenesis. The anti-angiogenic drugs currently available on the market are bevacizumab (Avastin ®), sunitinib (Sutent ®) and sorafenib (Nexavar ®). The mechanism of anti-angiogenic action of these three main drugs are pharmacological inhibition of the VEGF pathway. These new anti-angiogenic therapies, however, have significant adverse effects are common and some other more serious but rare. Hypertension is the most common side effect observed in patients treated with anti-VEGF. This is usually iatrogenic hypertension controlled by antihypertensive therapy and rarely compromises the pursuit of anti-angiogenic therapy. More rarely, it can have serious consequences malignant hypertension, severe hypertension refractory reversible posterior leukoencephalopathy associated with severe hypertension have also been reported. The pathophysiology of hypertension may be due to the neutralization of major physiological effects of VEGF in endothelial cell and therefore the vascular wall. The study of the microcirculation is not only useful in the diagnosis of microvascular but also macrovascular disease in the evaluation of chronic arterial and venous severe it determines the prognosis. In these indications, capillaroscopy remains the gold standard for all work pathophysiological because visualization of phenomena measured avoids artifacts and difficulties of interpretation. It then appealed to additional technology to directly measure the capillary pressure, capillary flow velocity, and indirectly assess capillary permeability and function of lymphatic canaliculi. The simplest of these technological inputs: video microscopy and digital image analysis, have also improved the practice of routine clinical capillaroscopy in its main field of application, evaluation of microangiopathy connective. The examination can be performed more quickly and easily archived and quantified. Only two studies on 14 and 16 patients were able to see a decrease in capillary density correlated with the therapeutic activity of anti-angiogenic the tumor mass and metastasis. Thus, we propose to quantify in a number of relatively large patient patients the decrease in capillary density as well as the relationship between the decrease in the number of capillaries and anti-tumor response. The study will also aim to measure the prevalence of hypertension in patients treated with bevacizumab and to establish the link between these data and the modification of the capillary microcirculation.
The purpose of this study is to assess if panitumumab is active enough to warrant comparative studies in patients with metastatic colorectal cancer that has progressed after treatment with cetuximab.
This non-interventional retrospective medical record review study will assess the prevalence of KRAS testing and the impact of the KRAS test result on patterns of Vectibix use in patients with metastatic colorectal cancer (mCRC) treated with Vectibix in selected European countries over 3 rounds. As the optimal use of Vectibix also requires accurate KRAS mutation testing, this study will also assess data from the laboratory that performed the KRAS test. The study will also monitor changes in the pattern of Vectibix treatment between the different rounds of the study.
The purpose of this study is to test a new drug combination consisting of two drugs, vemurafenib (also known as ZelborafTM) and panitumumab (also known as VectibixTM). This treatment is being tested in a subgroup of patients with colorectal cancer whose tumors have changes in the BRAF gene that may make them more likely to respond to this new drug combination.
