Paclitaxel combined with bevacizumab prolongs progression free survival for patients with metastatic breast cancer

23.03.2006
Results from a large, randomised clinical trial for patients with breast cancer show that those who received bevacizumab (Avastin) in combination with paclitaxel (Taxol) survived without the disease getting worse for almost twice as long as patients who received paclitaxel alone. The results were announced today at the 5th European Breast Cancer Conference (EBCC-5).

A total of 722 patients with locally recurrent or metastatic breast cancer were enrolled in the study. Patients were randomised into two treatment groups. One group received the standard treatment, paclitaxel alone and the second group received the new drug combination of paclitaxel with bevacizumab. Researchers found that patients who received bevacizumab in combination with paclitaxel had significantly improved progression free survival of 11.4 months, compared to 6.11 months with paclitaxel alone - a statistically significant difference. Initial overall survival data is also promising and shows a trend towards improved overall survival (28.4 vs 25.2 months) with the new drug combination.

"These results are good news for people with breast cancer," said the study author Dr. R. Zon, Michiana Hematology Oncology, P.C. USA, adding, “A drug with a novel mode of action on the blood vessels within the cancer has not added side effects for patients and those who received the test drugs kept their cancer under control for almost twice as long as patients who received the standard regimen. The next step will be introducing the new drug in patients whose breast cancer has not progressed to metastasis."

The clinical trial was sponsored by the National Cancer Institute (NCI) and conducted by a network of researchers led by the Eastern Cooperative Oncology Group (ECOG), one of the largest clinical cancer research organisations in the U.S. The promising trial results showed only a minimal increase in toxicity when bevacizumab was added to paclitaxel. Manageable side effects of the drug combination included high blood pressure and bleeding.

The antibody drug bevacizumab works by blocking angiogenesis – the formation and growth of new blood vessels – by targeting a protein called vascular endothelial growth factor (VEGF). Cancerous tumours form a network of blood vessels in order to assist their growth, so by blocking the formation of new blood vessels to the tumour it will stop growing and eventually suffocate to death. The drug paclitaxel works by slowing or stopping the division of cancer cells in the body. It affects the cell structures called microtubules, which play an important role in cell function. The combination of the two drugs bevacizumab and paclitaxel enable the cancer cells themselves to be attacked as well as the cancer cell’s support system, (the blood vessels that feed the tumour).

Im Focus: Can we see monkeys from space? Emerging technologies to map biodiversity

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.

Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...

Im Focus: Climate satellite: Tracking methane with robust laser technology

Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.

Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...

Im Focus: How protons move through a fuel cell

Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.

As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...

Im Focus: A unique data centre for cosmological simulations

Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.

With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
