Palliative radiation actually a cure for some lung cancer patients

23.01.2006


About one in a hundred patients with apparently incurable non-small cell lung cancer (NSCLC) survive five or more years after being given relatively small doses of radiation therapy (RT) meant to ease symptoms, according to a new study. Published in the March 1, 2006 issue of CANCER, a peer-reviewed journal of the American Cancer Society, the study says a new subset of patients with NSCLC appears to have disease that is curable with minimal therapy, and may explain occasional cures attributed to unconventional therapies or faith healing.



NSCLC is by far the most common type of lung cancer. With an overall five year survival of only 40 percent, it is also one of the deadliest. If caught early, five year survival can reach 60 percent. Five year survival in farther advanced disease is approximately 15 percent.

Patients who are diagnosed with disease that is too advanced for curative treatment remain eligible for palliative therapies intended to provide symptom relief, including comparatively low doses of localized RT. Physicians have long made clinical observations that some patients receiving palliative RT long outlive their estimated survival and a few report even cures. Given that therapeutic doses of RT are much higher, it is not surprising that these reports require evidence-based confirmation.


Michael Mac Manus, M.D., a radiation oncologist at the Peter MacCallum Cancer Centre in Melbourne, Australia, and colleagues clinically followed 2337 confirmed and apparently incurable NSCLC patients who had received palliative dose RT.

Approximately 1.1 percent of the 2337 survived five or more years, including 18 who achieved an apparent cure. Although five year survivors were more likely to have higher functional scores at diagnosis and less likely to have metastatic disease compared to patients who lived less than five years, there were no other conventional prognostic factors to predict survival with palliative-dosed RT.

"Our data," conclude the researchers "show that close to 1 percent of patients with NSCLC have prolonged survival with doses of palliative RT that would not normally be considered sufficient for long term disease control." Future studies should focus on identifying patient characteristics because "prospective identification of such patients could potentially profoundly influence treatment."

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...

Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.

Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

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.
