Online Tool Estimates Long-Term Chance of Surviving Prostate Cancer
A study just completed by researchers at the Josephine Ford Cancer Center has resulted in the most comprehensive long-term prostate cancer survival model available to date. An interactive version of the survival model is available online at prostatecalculator.org. Patients and doctors who visit the site can obtain a personalized 10-year survival estimate based on age, race, a few clinical measures, and the kind of treatment being pursued. Once data have been entered, a simple mouse-click provides the prognosis.
Dr. Ashutosh Tewari, with the Josephine Ford Cancer Center (Detroit, MI) worked with investigators at ANNs in CaP (Denver, CO) to retrospectively identify a cohort of 1,611 patients with clinically localized prostate cancer as well as 4,538 age, race, and co-morbidity (those with additional diseases) matched controls. Based on demographic and clinical variables, propensity risk scoring was used to develop survival probability estimates for both patients and controls. Because the calculator, and the companion look-up tables published in the April issue of the Journal of Urology, provide a comparison with men with similar characteristics but who do not have prostate cancer, users receive a realistic estimate of the impact of prostate cancer on long-term survival.
Prostate cancer is the most common solid-organ male malignancy diagnosed in the United States, with an estimated 189,000 new cases each year. Currently, African-American men have the highest incidence of prostate cancer in the world (137 per 100,000 per year), and are 2.5 times as likely to die as whites. While the reason for this is not known, some research suggests that black men are often diagnosed at later disease stages. Dr. Tewari adds, "Our research indicates that African-American men also tend to undergo less aggressive treatment than whites, and additional studies by our group suggest that if they received the same treatments, their prostate cancer survival rates would be much closer to those of whites." The study also showed that a man’s level of co-morbidities can have as much or more of an impact on his chances of long-term survival than his prostate cancer alone.
This new prostate cancer survival model is the most comprehensive to date because it provides an estimate of the likelihood of survival taking into account a patient’s age, race, comorbities, and treatment type. According to Dr. Tewari, "While the study was not a randomized controlled trial comparing surgery, radiation therapy, and watchful waiting, the method we used has been shown to eliminate much of the bias introduced with a non-randomized study design. And the inclusion of a large, matched control group is a great strength of our study."
While the study, which was awarded a first prize by the American Urological Association, adds to the knowledge of how co-morbidities and race affect the long-term survival of men with prostate cancer, an additional benefit is that it prompted Dr. Tewaris team to ask and seek answers to new questions: Why do black men receive less aggressive treatment than whites? Are black men choosing less aggressive treatment themselves or are their doctors suggesting the treatment? And, finally, is it worthwhile for men with additional diseases to treat their prostate cancer?

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
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,...
