Tumor size can predict the survival of a patient with the most common type of lung cancer, according to physician-scientists at NewYork Weill Cornell Medical Center. The study, which is the lead paper in this months Chest, emphasizes the need for further substaging in lung cancer and suggests the importance of early detection by CT scans.
The study evaluates the relationship between tumor size and five-year survival in patients with stage IA non-small cell lung cancer (NSCLC). Researchers reviewed the history of 244 patients treated at NewYork-Presbyterian Hospital/Weill Cornell Medical Center who underwent surgical resection for lung tumors between 1991 and 2001. Overall survival rates and survival rates specific to lung cancer were analyzed and compared to tumor size. The overall five-year survival rate for all patients was 71.1 percent, and the five-year disease-specific survival was 74.9 percent. Significantly, tumor size was an important predictor of long-term survival: disease-specific survival was 81.4 percent for patients with tumors less than or equal to 2.0 cm and only 63.4 percent for patients with tumors greater than 2.0 cm.
"These findings should encourage CT screening, which can detect tumors smaller than one centimeter," says Dr. Nasser K. Altorki, the studys principal investigator, Professor of Cardiothoracic Surgery at Weill Cornell Medical College, and Director of the Division of Thoracic Surgery at NewYork-Presbyterian Hospital/Weill Cornell Medical Center. "The message is clear: early detection of tumors means better odds of survival."

In just a few weeks from now, the Chinese space station Tiangong-1 will re-enter the Earth's atmosphere where it will to a large extent burn up. It is possible that some debris will reach the Earth's surface. Tiangong-1 is orbiting the Earth uncontrolled at a speed of approx. 29,000 km/h.Currently the prognosis relating to the time of impact currently lies within a window of several days. The scientists at Fraunhofer FHR have already been monitoring Tiangong-1 for a number of weeks with their TIRA system, one of the most powerful space observation radars in the world, with a view to supporting the German Space Situational Awareness Center and the ESA with their re-entry forecasts.
Following the loss of radio contact with Tiangong-1 in 2016 and due to the low orbital height, it is now inevitable that the Chinese space station will...

For the first time, an interdisciplinary team from the University of Basel has succeeded in integrating artificial organelles into the cells of live zebrafish embryos. This innovative approach using artificial organelles as cellular implants offers new potential in treating a range of diseases, as the authors report in an article published in Nature Communications.
In the cells of higher organisms, organelles such as the nucleus or mitochondria perform a range of complex functions necessary for life. In the networks of...
