Smoking does not lead to more aggressive or advanced breast cancers

30.10.2007
Smoking cigarettes is associated with an increased risk of cancers of the lung, head and neck, esophagus, bladder and many others and also affects response to anti-cancer treatments.

But smoking does not result in more advanced stage diagnoses or aggressive breast cancers at the time of diagnosis. That is the result of an analysis of 35 years of data for more than 6,000 patients presented today at the American Society for Therapeutic Radiology and Oncology’s 49th Annual Meeting in Los Angeles.

“We hypothesized that tobacco use could result in more advanced stage or more aggressive breast cancer presentation, but that doesn’t appear to be the case,” said Matthew Abramowitz, M.D.,a resident in the radiation oncology department at Fox Chase Cancer Center. “There is no good news about smoking, but since about 10 percent of our patients are smokers, this research provides us with some relief. The question that remains is will smoking affect their survival?”

Abramowitz and his colleagues examined the medical records of 6,162 breast cancer patients at the time of initial diagnosis from 1970 to 2006 at Fox Chase Cancer Center in Philadelphia. Patient characteristics were prospectively collected by physician interview and questionnaire. Nine percent of the patients were current smokers when they were first seen for consultation.

“There was no statistically significant correlation between smoking and the stage of the disease or the aggressiveness of the tumor,” concluded Abramowitz. “The remaining question is does smoking affect how long these women live? In other words, does smoking affect the tumor’s behavior, its effect on the treatment to kill the cancer or recovery from treatment?”

Im Focus: New interactive machine learning tool makes car designs more aerodynamic

Scientists develop first tool to use machine learning methods to compute flow around interactively designable 3D objects. Tool will be presented at this year’s prestigious SIGGRAPH conference.

When engineers or designers want to test the aerodynamic properties of the newly designed shape of a car, airplane, or other object, they would normally model...

Im Focus: Robots as 'pump attendants': TU Graz develops robot-controlled rapid charging system for e-vehicles

Researchers from TU Graz and their industry partners have unveiled a world first: the prototype of a robot-controlled, high-speed combined charging system (CCS) for electric vehicles that enables series charging of cars in various parking positions.

Global demand for electric vehicles is forecast to rise sharply: by 2025, the number of new vehicle registrations is expected to reach 25 million per year....

Im Focus: The “TRiC” to folding actin

Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.

Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...

Im Focus: Lining up surprising behaviors of superconductor with one of the world's strongest magnets

Scientists have discovered that the electrical resistance of a copper-oxide compound depends on the magnetic field in a very unusual way -- a finding that could help direct the search for materials that can perfectly conduct electricity at room temperatur

What happens when really powerful magnets--capable of producing magnetic fields nearly two million times stronger than Earth's--are applied to materials that...

Im Focus: World record: Fastest 3-D tomographic images at BESSY II

The quality of materials often depends on the manufacturing process. In casting and welding, for example, the rate at which melts solidify and the resulting microstructure of the alloy is important. With metallic foams as well, it depends on exactly how the foaming process takes place. To understand these processes fully requires fast sensing capability. The fastest 3D tomographic images to date have now been achieved at the BESSY II X-ray source operated by the Helmholtz-Zentrum Berlin.

Dr. Francisco Garcia-Moreno and his team have designed a turntable that rotates ultra-stably about its axis at a constant rotational speed. This really depends...
