The study was published in the May issue of the Journal of Thoracic Oncology, the official journal of the International Association for the Study of Lung Cancer. Dr. Asamura and his team found that after classifying patients based on the technique used to diagnose their lung cancer, either through CT scans or x-rays, there was a marked difference in five-year survival rates. Those patients diagnosed using CT scans had a 91.2 percent 5-year survival rate while those diagnosed with x-rays demonstrated a 77.8 percent survival rate.
The researchers also divided the patients into groups based on the detection type, including screen detection, symptom detection and incidental detection. The patients that demonstrated the highest five-year survival rates were those diagnosed through screening (79.6 percent) and then those diagnosed because of symptoms (74.6 percent). The patients that were diagnosed incidentally demonstrated the lowest five-year survival rate (64.6 percent).
The study findings demonstrate the impact of lung cancer screening, particularly though CT-scans, can have on improving patient prognosis by detecting the disease at an early stage. The accuracy of CT scans allow physicians to detect cancerous growths while the tumor is at an early stage and physically smaller, making it more operable. With lung cancer prognosis and survival depending heavily on the stage of the disease upon diagnosis, it is important to keep findings such as these in mind.
Journal of Thoracic Oncology (JTO)
The JTO is rapidly becoming a prized resource for medical specialists and scientists who focus on the detection, prevention, diagnosis and treatment of lung cancer. The JTO is the official monthly journal of the International Association for the Study of Lung Cancer (IASLC.org) and emphasizes a multidisciplinary approach, including original research (clinical trials and translational or basic research), reviews and opinion pieces.

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,...
