Video-assisted thoracic surgery valuable tool in lung cancer screening

16.05.2012
CT screening of high-risk Danish population yields higher incidence of early stage lung cancer amenable to VATS resections

The most recent research released in June's Journal of Thoracic Oncology says video assisted thoracic surgery (VATS) is a valuable tool in managing lesions detected in a lung cancer screening program. The primary objective of lung cancer screening with low dose computer tomography (CT) is to detect lung cancer at an early stage and thus amenable to a complete surgical resection, the only established cure for lung cancer.

Lung cancer currently has no standard screening program and less than one third of lung cancer patients present with early stage disease amenable to cure. One of the concerns regarding lung cancer screening is how to manage detected lung nodules, the majority of which are benign.

The Danish study, presented in the June 2012 issue of the International Association for the Study of Lung Cancer's (IASLC) Journal of Thoracic Oncology, evaluated the role of VATS resection in a CT screened (2,052) versus unscreened (2,052) high risk Danish population from the Danish Lung Cancer Screening Trial. The study is a randomized clinically controlled trial comparing 5 annual CT screening rounds with no screening in 4104 individuals.

Sixty-eight (3.3%) lung cancers were detected in the screened population versus 24 (1.2%) in the unscreened population. Fifty-one of the 68 patients with lung cancer in the screened group were candidates for surgery for cure and 84 percent of these had VATS versus 50 percent in the unscreened group. Eight patients in the screened group had lesions highly suspicious for cancer that proved to be benign once removed by VATS.

Although the comparison groups were too small to detect a difference in this study, previous studies have found VATS to confer advantages over thoracotomy with respect to reduced post-operative pain, shorter hospital stay, more rapid resumption of normal daily activities, less impairment in pulmonary function, less impairment in shoulder function, reduced cytokine release, decreased time to initiation of adjuvant chemotherapy, lower incidence of complications and economic advantages. Thus, the ability to perform VATS, compared to thoracotomy, more frequently in the screened versus unscreened population, is potentially a very significant finding.

"We believe that it is of upmost importance for future low dose CT screening trials to have thoracic surgeons involved in the early detection program and that the thoracic surgeons should have a dedicated VATS program," the authors say.

The lead author of this work is Dr. Rene Petersen. Dr. Jesper Pedersen is co-author of the article and an IASLC member.

About the IASLC:

The International Association for the Study of Lung Cancer (IASLC) is the only global organization dedicated to the study of lung cancer. Founded in 1974, the association's membership includes more than 3,500 lung cancer specialists in 80 countries. To learn more about IASLC please visit www.iaslc.org.

Im Focus: Future electronic components to be printed like newspapers

A new manufacturing technique uses a process similar to newspaper printing to form smoother and more flexible metals for making ultrafast electronic devices.

The low-cost process, developed by Purdue University researchers, combines tools already used in industry for manufacturing metals on a large scale, but uses...

Im Focus: First evidence on the source of extragalactic particles

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.

To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...

Im Focus: Magnetic vortices: Two independent magnetic skyrmion phases discovered in a single material

For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.

Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...

Im Focus: Breaking the bond: To take part or not?

Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.

A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...

Im Focus: New 2D Spectroscopy Methods

Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.
