Decrease in the use of radiotherapy procedures in favour of chemotherapy for the treatment of cancer in hospitals

08.10.2007
According to the study carried out at the Department of Radiology and Physical Medicine (departamento de Radiología y Medicina Física) [http://www.ugr.es/~dptorad/] of the Universidad de Granada [http://www.ugr.es], in Andalusian hospitals radiotherapy is not used as much as should be expected for the treatment of cancer, in favour of other procedures such as chemotherapy or surgery.

The study, carried out by Doctor Patricia Cabrera Roldán, and directed by Professor José Expósito Hernández, revealed that the application of radiotherapy treatment often exceeds appropriate time limits, and varies a lot depending on the hospital in which such treatment is applied.

This study is based on the data of patients, treated in any of the 10 Andalusian public hospitals during a period of one year, who were submitted to radiotherapy procedures for the treatment of tumours in the breast, lung, head and neck, cervix and endometrium. The researchers’ main objectives were to analyse the frequency of application of radiotherapy treatment in patients suffering from cancer (rate of radiation) and to determine the existence of substantial differences in the application of radiotherapy treatment among different hospitals.

The scientists from the Universidad de Granada [http://www.ugr.es] revealed that, in Andalusia, radiotherapy procedures vary depending on the hospital in which they are applied. The main differences affected are: common treatment procedures (purpose and type of treatment, simulation methods used in the treatment, immobilisers or verification systems) and the definition of the treatment itself (total dose and treatment volume).

Less than desired

According to Patricia Cabrera Roldán, “Radiotherapy is not used as much as expected for the treatment of cancer in the hospitals analysed”, pointing out that this statement applies to the five hospitals studied. Finally, Patricia states that this fact is partly caused “by the incomplete equipping of the hospitals’ high-energy units”, but also by the doctors’ preferences, since application of radiotherapy “varies among the hospitals studied, even when an equal number of treatment machines are available for use”.

The study also reveals that, generally, patients start their first treatment of the illness on time and without inappropriate delays. “even though the application of radiotherapy treatment often exceeds appropriate time limits, and varies depending on the hospital in which such treatment is applied”. According to researchers, this excess of time may be caused by the fact that most of the patients receive treatment combined with surgery, radiotherapy and chemotherapy. This fact may represent a methodological problem of the study.

In light of these results, the Scientists think that health authorities should, on the first hand, adjust the material means necessary for the treatment of cancer in Andalusia; on the other hand, they should improve the introduction of cancer treatment protocols, agreed and based on scientific evidence.

Cancer is the second main cause of death in our society after cardiovascular diseases. However, it is stimated that in the 21 century, cancer will become the leading cause of death.

Im Focus: A Challenging European Research Project to Develop New Tiny Microscopes

The Institute of Semiconductor Technology and the Institute of Physical and Theoretical Chemistry, both members of the Laboratory for Emerging Nanometrology (LENA), at Technische Universität Braunschweig are partners in a new European research project entitled ChipScope, which aims to develop a completely new and extremely small optical microscope capable of observing the interior of living cells in real time. A consortium of 7 partners from 5 countries will tackle this issue with very ambitious objectives during a four-year research program.

To demonstrate the usefulness of this new scientific tool, at the end of the project the developed chip-sized microscope will be used to observe in real-time...

Im Focus: Giant Magnetic Fields in the Universe

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.

The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...

Im Focus: Polymer-coated silicon nanosheets as alternative to graphene: A perfect team for nanoelectronics

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.
