Certain genetic variants may put bladder cancer patients at increased risk of recurrence

26.03.2014

In the Western world, bladder cancer is the fourth most common cancer in men and the eighth most common in women, with many patients experiencing recurrence after treatment.

 A new study published in BJU International indicates that inheriting certain DNA sequences can affect a patient's prognosis. The findings may help physicians identify sub-groups of bladder cancer patients who should receive intensive treatment and monitoring.

Nearly half of patients diagnosed with bladder cancer experience tumor recurrences, but it is difficult to predict which patients are at risk. Angeline Andrew, PhD, of the Dartmouth-Hitchcock Norris Cotton Cancer Center in Lebanon, New Hampshire and her colleagues analyzed the genes of 563 patients to identify genetic variants that modify time to bladder cancer recurrence and patient survival.

The investigators isolated DNA from immune cells circulating in the blood, and they examined genes involved in major biological processes linked to cancer: cell death, proliferation, DNA repair, hormone regulation, immune surveillance, and cellular metabolism.

After diagnosis, patients were followed over time to ascertain recurrence and survival status. Patients were followed for a median of 5.4 years, and half of patients experienced at least one recurrence.

The team found that patients with variants in the aldehyde dehydrogenase 2 (ALDH2) gene were likely to experience bladder cancer recurrence shortly after treatment. This gene encodes an enzyme involved in alcohol metabolism.

Time to recurrence was also shorter for patients who had a variant in the vascular cellular adhesion molecule 1 (VCAM1) gene and were treated with immunotherapy. VCAM1 encodes a glycoprotein involved in the development of lymphoid tissues. Patients who had non-invasive tumors and a variant in the DNA repair gene XRCC4 tended to live longer than patients who did not have the variant.

The researchers noted that the novel associations between genetic variants and bladder cancer recurrence uncovered in this study merit future investigation. "The genetic markers that we found could potentially be useful for individually tailoring surveillance and treatment of bladder cancer patients," said Dr. Andrew.

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.
