Led by Michael J. Hassett, MD, MPH, of Dana-Farber, researchers studied a database of medical claims made by women with newly diagnosed breast cancer who had employer-provided health insurance between January 1998 and December 2002.
"This is the first study, to our knowledge, of chemotherapy-related serious adverse effects in a population-based sample of younger women with breast cancer," said Hassett, who is also an instructor in medicine at Harvard Medical School. "We found that eight chemotherapy-related serious adverse effects may be more common than reported in large clinical trials, and, therefore, these adverse effects may be responsible for more patient suffering and higher health care expenditures than currently predicted."
Doctors often prescribe chemotherapy to eliminate residual cancer cells in women who have undergone surgery for breast cancer. Women who received chemotherapy were more likely to be hospitalized or visit emergency rooms for problems that are typically related to chemotherapy, including fever or infection, low white blood cell or platelet count, nausea, diarrhea, malnutrition, or dehydration.
Researchers studied 7,052 women from a database of claims made to health plans that contract with large employers in the U.S. The group was equally divided into two cohorts of 3,526: those who received chemotherapy within 12 months of their first breast cancer diagnosis, and those who did not.
In addition to more incidents of chemotherapy-related adverse effects, women undergoing chemotherapy for breast cancer also experienced increased healthcare costs: $1,271 more per year for hospitalizations and emergency room visits and $17,617 more per year for ambulatory care than women who did not receive chemotherapy.

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...
Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...
A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
