Spanish researchers led by Dr. Emilio Alba have been studying the effects of pegylated liposomal doxorubicin in a group of 155 women who had already been treated with chemotherapy.
At the 33rd Congress of the European Society for Medical Oncology (ESMO) in Stockholm, they present long-term follow-up data showing that 81% of patients prescribed the drug were alive after one year, compared to 66% of those who did not receive the treatment.
The aim of the therapy was to delay progression of disease while inflicting as few side-effects as possible, said Dr. Alba.
“Despite major advances in adjuvant therapy, the number of patients with metastatic breast cancer who are expected to relapse is substantial,” he said. “In this setting the treatment is not curative, but it is important to explore all the available alternatives.”
“In the case of chemotherapy, toxicity is the main drawback. Almost all studies carried out up to now associate maintenance therapy with a longer time-to-progression, and sometimes more overall survival. However, dealing with toxicity forces us to balance benefits and risks.”
“The main finding of this trial was the low toxicity profile of pegylated liposomal doxorubicin at a dose of 40mg/m2. This dose presented no gastrointestinal toxicity, no grade IV alopecia, and grade IV adverse effects such as mucositis or hand-and-foot syndrome (HFS) were lower than 5%. The treatment also presented no cardiotoxicity. The subjective tolerance was very good.”
Women treated with the drug saw a mean increase in time-to-progression of 3.4 months, the researchers found, which is similar to that of new targeted drugs such as trastuzumab or lapanitib. “While a month would probably fall short, a recent survey indicated 51% of oncologists would consider a time-to-progression increase of 3 months as successful,” Dr. Alba said.
“Maintenance therapy is a good option for almost everybody, if we can design effective treatments associated with a good toxicity profile. I think this goal is achieved in the case of pegylated liposomal doxorubicin,” he said.

In just a few weeks from now, the Chinese space station Tiangong-1 will re-enter the Earth's atmosphere where it will to a large extent burn up. It is possible that some debris will reach the Earth's surface. Tiangong-1 is orbiting the Earth uncontrolled at a speed of approx. 29,000 km/h.Currently the prognosis relating to the time of impact currently lies within a window of several days. The scientists at Fraunhofer FHR have already been monitoring Tiangong-1 for a number of weeks with their TIRA system, one of the most powerful space observation radars in the world, with a view to supporting the German Space Situational Awareness Center and the ESA with their re-entry forecasts.
Following the loss of radio contact with Tiangong-1 in 2016 and due to the low orbital height, it is now inevitable that the Chinese space station will...

For the first time, an interdisciplinary team from the University of Basel has succeeded in integrating artificial organelles into the cells of live zebrafish embryos. This innovative approach using artificial organelles as cellular implants offers new potential in treating a range of diseases, as the authors report in an article published in Nature Communications.
In the cells of higher organisms, organelles such as the nucleus or mitochondria perform a range of complex functions necessary for life. In the networks of...
