New Studies in Lung Cancer News
Advances in the treatment of small cell and non-small cell carcinoma in the lungs show promising results for future cures. The lung cancer news articles detail studies using nano-particles to detect and attack, advances in radiation therapy and potential vaccines for the future.
Nano-science uses programmed microscopic particles to carry out a task. Scientists at MIT have invented a method to send these particles into the body to attack cancer cells. In their study, mice with lung tumors were injected with T-cells, the body’s immune defense system, carrying the particles with them. On a time-release, the drug molecules seeped into the system gradually, and multiplied by marrying themselves to their host cells. Within days, the tumors had disappeared, extending the life cycle of the survivors by seventy-five days.
This innovative experiment began by removing T-cells from the mouse and modifying them with the nano particles. In a similar study published by the National Institute of Health, the nano molecules were used to suppress the immune response in human subjects during organ transplantation. The study delivered chemotherapy drugs to aid as an immunosuppressant.
Penn State chemical researchers used this same principle to deliver chemotherapy drugs to the site of a tumor and destroy it. Normally, the potential side effects in humans include rejection of the nano particles by the body. The Penn State team prevented this by hiding the ‘drug-charged core’ in a polymer shell.
Early detection of small cell carcinoma lung cancer has been a problem in the past. Over the last few years, researchers have developed a breath test which diagnoses this cancer. Screening is performed with the aid of gold nano particles and has demonstrated 86 percent accuracy. The particles detect ‘volatile organic compounds’ found in cancerous lung tissue and are inexpensive. Hossam Haick of the Israeli scientific team developing the sensor, expects it to be available in three to five years.
Science has created innovative methods of targeting and treating cancer in the lungs, but not all experiments are futuristic. According to a Reuter’s Health article by Kate Kelland, dogs have been trained to detect cancer on human breath for years with almost 100 percent accuracy.
