Race and gender affect lung cancer clinical trial participation

12.12.2005


A new study finds significant disparities by race and gender in the enrollment of patients into lung cancer clinical trials. Published in the January 15, 2006 issue of CANCER, a peer-reviewed journal of the American Cancer Society, the study indicates that women and African-Americans were least likely to enroll in treatment trials for lung cancer, and identifies a need to improve educational and outreach efforts to make clinical trials available to a wider range of patients.



While clinical trials are important because they test the efficacy of the next generation of potentially life-saving treatments, only five percent of cancer patients participate in clinical trials. Reports have demonstrated that systemic factors in the healthcare system, such as cost, patient education, and physician biases may explain the low accrual rates. But gender and racial inequalities also are apparent, forcing lawmakers in 1993 to direct the healthcare system to encourage women and minority participation. Not only does lack of participation by minorities and women shut them out of the next generation of potentially life-saving treatment, but it also makes it all the more difficult for clinicians to translate treatment benefits and risks found in a clinical trial to these under-represented patient populations.

To evaluate the enrollment rate and the factors predicting enrollment, Wei Du, Ph.D., and colleagues from Wayne State University reviewed data from 427 lung cancer patients (175 African-Americans and 252 from other races) who were eligible for clinical trials between 1994 and 1998 at one center, the Karmanos Cancer Institute in Detroit.


Of this group, 21 percent (91 patients) participated in a lung cancer treatment clinical trial. The researchers found that patients who did not participate were more likely to be African American (45 percent versus 25 percent of enrollees), female (43 percent versus 32 percent of enrollees), and over the age of 70 (24 percent versus 10 percent of enrollees). The researchers say their results should be viewed with caution given that the study looked at enrollment at a single medical center, and did not study other factors that may play a role in clinical trial participation. Those include a lack of trust in the medical establishment, lack of knowledge about clinical trials, and the effect of religious belief or spirituality on the willingness to participate.

Still, they conclude: "New recruitment strategies targeting specific patient subgroups might be helpful in ensuring equal representation of women and minority groups in cancer clinical trials."

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

Im Focus: RAVAN CubeSat measures Earth's outgoing energy

An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.

The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...

Im Focus: Scientists improve forecast of increasing hazard on Ecuadorian volcano

Researchers from the University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science, the Italian Space Agency (ASI), and the Instituto Geofisico--Escuela Politecnica Nacional (IGEPN) of Ecuador, showed an increasing volcanic danger on Cotopaxi in Ecuador using a powerful technique known as Interferometric Synthetic Aperture Radar (InSAR).

The Andes region in which Cotopaxi volcano is located is known to contain some of the world's most serious volcanic hazard. A mid- to large-size eruption has...
