Minimally invasive surgery may increase options for octogenarians with some lung cancers

10.11.2005


Like their younger counterparts, some elderly patients who have early stage non-small cell lung cancer can benefit from a minimally invasive surgical procedure to remove part or all of a lung, according to a study conducted by thoracic surgeons at Cedars-Sinai Medical Center and described in the current issue of The American Surgeon, the journal of the Southeastern Surgical Congress and the Southern California Chapter of the American College of Surgeons.



When non-small cell lung cancers (NSCLC) are detected at an early, localized stage, surgical removal of the affected area often can prevent metastasis to other tissues and organs. But while some patients, including the elderly, might not be good candidates for the physical demands of open chest surgery, this study of 159 patients between ages 80 and 94 suggests that video-assisted thoracoscopic surgery should be considered a viable option.

"Some patients and their doctors wonder why a person that age should bother to go through any major pulmonary surgery. The reason is that whether the patient is 80 or 95, if they are in reasonably good physical condition without any other major medical problems that are imminently life threatening, the odds are that the cancer is going to progress and the patient will live long enough to go through several unpleasant months with widespread cancer," said Robert McKenna Jr., M.D., thoracic surgeon, surgical director of the Center for Chest Diseases and chief of Thoracic Surgery and Trauma at Cedars-Sinai.


"Our study shows that we can do a standard, complete lung cancer surgery in people over 80 with very low risk and good success so that older patients with lung cancer do not have to suffer the consequences of widespread cancer," said McKenna, senior author of the journal article.

According to previous studies, the average 80-year-old can expect to live another 8.6 years, but the average life expectancy of a patient with untreated or palliated early-stage NSCLC is only 1.5 years.

"If you knew that you could get several additional years to live by having a procedure with low risk and good success in preventing widespread cancer, you might want the option of putting up with the short-term inconvenience of having that operation," McKenna said.

In the study, there were no surgery-related deaths and relatively few complications. "Compared to the percentage of people who experience any type of complication after a major pulmonary resection, our numbers were low, and especially low for patients in this age range," said McKenna.

Open surgery – accomplished through an eight- to 10-inch incision – continues to be used in about 95 percent of lobectomies nationally. McKenna and his colleagues at Cedars-Sinai, however, use the minimally invasive approach in 89 percent of their cases. VATS requires only several small incisions through which instruments and a thoracoscope are inserted. A camera lens at the tip of the scope feeds high-resolution images to a video monitor, giving the surgeon a detailed, magnified view.

"We have been doing minimally invasive lung cancer surgery for a long time and have the largest experience in the world," said McKenna, a pioneer in the development and use of the technology who has performed VATS procedures since 1989. "We follow our patients carefully and have shown that this is the standard cancer operation with the same survival rates as with invasive surgery, but it has tremendous advantages for patients. The stay in the hospital is less and the complication rate is less. It is not pain-free, but patients are able to recover more quickly and get back to their regular activities much more quickly with this operation."

The term non-small cell lung cancer includes several types of lung cancer that when detected at an early and localized stage may be cured with surgical resection. NSCLC accounts for about 75 percent of all lung cancers.

Im Focus: Can we see monkeys from space? Emerging technologies to map biodiversity

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.

Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...

Im Focus: Climate satellite: Tracking methane with robust laser technology

Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.

Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...

Im Focus: How protons move through a fuel cell

Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.

As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...

Im Focus: A unique data centre for cosmological simulations

Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.

With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
