(Press-News.org) DENVER – The average cost to screen high-risk individuals for developing lung cancer with low-dose computed tomography (LDCT) plus the average cost of curative intent treatment, like surgery, is lower than the average cost to treat advanced stage lung cancer, which quite rarely results in a cure.
The National Lung Cancer Screening Trial (NLST) has previously shown that LDCT screening of people at high-risk for lung cancer reduces lung cancer mortality by 20%, thus many organizations including the United States Preventative Services Task Force (USPSTF) have recommend LDCT screening for these individuals. It is thought that if lung cancer is detected at an early stage with screening that it can be cured and the consequences of this are a significant reduction in lung cancer mortality, as the 5-year survival rate for early-stage disease is 54%, and a reduction in the need for expensive and toxic treatments for advanced late-stage lung cancer, which seldom results in a cure as reflected by a 5-year survival rate of 4%. However, in the US 8.6 million people meet the high-risk criteria, which could equate to a significant screening cost.
The Pan-Canadian Early Detection Study prospectively examined the costs for the resources used to screen annually, treat (if necessary), and follow for 2 years 2059 participants who had a 2% or greater risk of developing lung over 3 years as determined by a Web-based lung cancer risk prediction tool.
The Journal of Thoracic Oncology, the official journal of the International Association for the Study of Lung Cancer, published these results in its October issue. The average cost per-person for at least 2 annual LDCT screens and all the necessary follow-up or repeat scans for those without lung cancer was $453 for the entire study period versus $2248 for those with lung cancer. The mean per-person cost for diagnostic workup, curative intent surgical treatment, and 2 years of follow-up was $33,344 for those diagnosed with lung cancer. In comparison the cost for treating advanced-stage lung cancer with chemotherapy, radiotherapy, or supportive care alone was $47,792.
"The number of deaths that potentially could be prevented and the number of life years gained with lung cancer screening using LDCT is greater than any new treatment modality offered over the last 2 decades", says the authors of the study. Additionally, "If expensive targeted-therapies become widespread in the treatment of advanced, inoperable lung cancer, a screening program could potentially become cost saving while at the same time improving patient outcomes". The authors also note that "our risk prediction tool has been found to have 11.9% greater sensitivity in identifying those who would be diagnosed with lung cancer in the 6 years of follow-up compared with the NLST criteria, thus reducing the number of people that needed to be screened to detect lung cancer and improving cost-effectiveness".

Customer experience matters more when economy is strong, research shows
2014-09-24
ATLANTA—Customers care more about their past experiences with service firms when the economy is doing well, according to a research team from the J. Mack Robinson College of Business at Georgia State University.
The researchers found it is more important for service firms to focus their resources and efforts on improving customer experience when economic times are good, as opposed to when the economy is down. This new finding contradicts previous beliefs that firms should increase their efforts to improve customer experience during difficult economic times to hold on ...
NRL researchers develop novel method to synthesize nanoparticles
2014-09-24
WASHINGTON – Scientists at the U.S. Naval Research Laboratory (NRL) Materials Science and Technology Division have developed a novel one-step process using, for the first time in these types of syntheses, potassium superoxide (KO2) to rapidly form oxide nanoparticles from simple salt solutions in water.
"Typically, the synthesis of oxide nanoparticles involves the slow reaction of a weak oxidizing agent, such as hydrogen peroxide, with dilute solutions of metal salts or complexes in both aqueous and non-aqueous solvent systems," said Dr. Thomas Sutto, NRL research chemist. ...
Most stars are born in clusters, some leave 'home'
2014-09-24
Washington, D.C.—New modeling studies from Carnegie's Alan Boss demonstrate that most of the stars we see were formed when unstable clusters of newly formed protostars broke up. These protostars are born out of rotating clouds of dust and gas, which act as nurseries for star formation. Rare clusters of multiple protostars remain stable and mature into multi-star systems. The unstable ones will eject stars until they achieve stability and end up as single or binary stars. The work is published in The Astrophysical Journal.
About two-thirds of all stars within 81 light ...
King Fire in California still blazing
2014-09-24
Over 92,960 acres have been burned by the King Fire since it began on September 13, 2014. The fire is currently 38% contained, and the cause of the fire is arson. Over 7,600 personnel are battling this fire.
With the southwest winds there is a potential for extreme fire behavior if the winds, fuels, and topography come into alignment. There is the possibility for single and group tree torching, upslope crown runs, and spotting up to 1/2 mile. The highest probability is on the northwest portion of the fire. A Red Flag warning remains in effect for this fire. A Red ...
Study: Pain keeps surgery patients awake, extends hospital stay
2014-09-24
DETROIT – Pain can make it difficult for some patients to get a good night's rest while recovering in the hospital following certain surgical procedures, often resulting in longer hospital stays, according to researchers at Henry Ford Hospital in Detroit.
The study shows patients who reported poor sleep while in the hospital following total hip replacement or knee replacement surgery had higher pain scores.
"Our results show that increased pain scores result in deceased sleep duration," says study lead author Anya Miller, M.D., with the Department of Otolaryngology-Head ...
Survey: Costs of ACA health insurance in Texas vary significantly depending on income
2014-09-24
HOUSTON – (Sept. 24, 2014) – The cost of monthly premiums for health insurance plans for Texans under the Affordable Care Act (ACA) can vary by hundreds of dollars, depending on a person's income and the level of coverage chosen, according to a report released today by the Episcopal Health Foundation and Rice University's Baker Institute for Public Policy.
The report found Texans earning about $17,000 a year were offered free premiums on some ACA Marketplace health insurance plans because of federal tax credits. However, a person who makes around $35,000 a year would ...
Organ donation: Do we opt-in or opt-out?
2014-09-24
Researchers say there should be an international database containing the very latest information about organ donations and transplants, so policy makers can make informed decisions on whether to adopt an opt-out or opt-in system.
The call comes after a study, carried out by The University of Nottingham, the University of Stirling and Northumbria University, showed that overall an opt-out system might provide a greater number of organs for transplant but many factors can influence the success of either system and a repository of accessible information would help individual ...

2014-09-24
On September 30, 2014, in Washington, DC, higher education and health leaders will release a report that is the first to examine nationwide the impact and use of holistic review—a university admissions process that assesses an applicant's unique experiences alongside traditional measures of academic achievement such as grades and test scores—for students pursuing careers in the health professions.
Many colleges and universities use a holistic admission process to select students. The practice has become more popular in health fields such as medicine, because it enables ...
Tonsil stem cells could someday help repair liver damage without surgery
2014-09-24
The liver provides critical functions, such as ridding the body of toxins. Its failure can be deadly, and there are few options for fixing it. But scientists now report in the journal ACS Applied Materials & Interfaces a way to potentially inject stem cells from tonsils, a body part we don't need, to repair damaged livers — all without surgery.
Byeongmoon Jeong and colleagues point out that currently, the only established method for treating liver failure or severe cases of liver disease is complete or partial transplantation. But the need is much greater than the number ...
