Researchers explore connection between popular pain relievers, bladder cancer

08.11.2012
Duration of ibuprofen use may be related to a reduced risk, especially in those with certain genetic marker

Dartmouth researchers have found that duration of ibuprofen use was associated with a reduced risk of bladder cancer in patients in northern New England, which has a high mortality rate of this disease.

In a 2012 collaborative project with the National Cancer Institute, Margaret Karagas, PhD, co-director, Cancer Epidemiology & Chemoprevention program at Norris Cotton Cancer Center, and Professor of Community and Family Medicine at the Geisel School of Medicine at Dartmouth, and Richard Waddell, D.Sc, Research Assistant Professor of Medicine at the Geisel School of Medicine, looked for connections between ibuprofen use and bladder cancer.

Bladder cancer and ibuprofen use

Karagas did an earlier study on the relationship between bladder cancer and nonsteroidal anti-inflammatory drugs (NSAIDs) usage in New Hampshire. The new study included patients in Vermont and Maine. Researchers enrolled 1,171 participants newly diagnosed with bladder cancer and 1,418 participants who did not have bladder cancer. Karagas also added a genetic component looking at thirty-nine genes related to NSAID metabolism and studied a new class of NSAIDs known as selective cyclooxygenase (COX-2) inhibitors, such as celecoxib (Celebrex). Their results were published in the International Journal of Cancer (June 2012).

Those with specific genetic traits appear to have reduced risk

The findings in the recent study suggest that "regular use of nonaspirin nonselective NSAIDs, particularly ibuprofen, may reduce bladder cancer risk, especially among regular users for 10 years or more." However, the study also notes that observed reduction in risk was specific to individuals carrying a specific allele (or variant of a gene) related to NSAID metabolism.

Findings suggest further study needed for newer prescription pain reliever

For Karagas one of the novel findings was a trend of an increased risk of bladder cancer for those using selective COX-2 inhibitors, especially celocoxib (Celebrex). Karagas warns against leaping to any conclusions, noting, "further investigation is needed."

Karagas also stresses that this study "does not make any recommendations. It does not, in any way, suggest that patients begin taking ibuprofen as a prophylactic measure against bladder cancer, nor should patients go off any medicine prescribed by their doctor."

This research study was funded by the National Institutes of Health Grant number: N02-CP-01037

About Norris Cotton Cancer Center at Dartmouth-Hitchcock

Norris Cotton Cancer Center combines advanced cancer research at Dartmouth College and the Geisel School of Medicine at Dartmouth with patient-centered cancer care provided at Dartmouth-Hitchcock Medical Center, at Dartmouth-Hitchcock regional locations in Manchester, Nashua, and Keene, NH, and St. Johnsbury, VT, and at 12 partner hospitals throughout New Hampshire and Vermont.

Im Focus: Significantly more productivity in USP lasers

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:...

Mapping the interaction of a single atom with a single photon may inform design of quantum devices

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

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...

Im Focus: Quantum Particles Form Droplets

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...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

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,...
