Type of lung cancer screening used to detect disease may impact 5-year survival rates

06.05.2009
Dr. Hisao Asamura and his team of researchers at The National Cancer Center Hospital in Tokyo, Japan examined the records of 2,281 patients who underwent lung cancer resection surgery between 2000 and 2006.

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.

Im Focus: Artificial agent designs quantum experiments

On the way to an intelligent laboratory, physicists from Innsbruck and Vienna present an artificial agent that autonomously designs quantum experiments. In initial experiments, the system has independently (re)discovered experimental techniques that are nowadays standard in modern quantum optical laboratories. This shows how machines could play a more creative role in research in the future.

Im Focus: The first precise measurement of a single molecule's effective charge

For the first time, scientists have precisely measured the effective electrical charge of a single molecule in solution. This fundamental insight of an SNSF Professor could also pave the way for future medical diagnostics.

Electrical charge is one of the key properties that allows molecules to interact. Life itself depends on this phenomenon: many biological processes involve...

Im Focus: Paradigm shift in Paris: Encouraging an holistic view of laser machining

At the JEC World Composite Show in Paris in March 2018, the Fraunhofer Institute for Laser Technology ILT will be focusing on the latest trends and innovations in laser machining of composites. Among other things, researchers at the booth shared with the Aachen Center for Integrative Lightweight Production (AZL) will demonstrate how lasers can be used for joining, structuring, cutting and drilling composite materials.

No other industry has attracted as much public attention to composite materials as the automotive industry, which along with the aerospace industry is a driver...

Im Focus: Room-temperature multiferroic thin films and their properties

Scientists at Tokyo Institute of Technology (Tokyo Tech) and Tohoku University have developed high-quality GFO epitaxial films and systematically investigated their ferroelectric and ferromagnetic properties. They also demonstrated the room-temperature magnetocapacitance effects of these GFO thin films.

Multiferroic materials show magnetically driven ferroelectricity. They are attracting increasing attention because of their fascinating properties such as...
