Lung cancer screening leads to high rates of false positives
The use of computed tomography (CT) to screen people for lung cancer leads to high rates of false positives, often triggering follow-up tests and invasive procedures, researchers said at the ASCO annual meeting. Concerns about the risks and benefits of lung cancer screening with CT have been raised previously, but this is the first report to quantify the risk of obtaining false-positive results.
Combo treatment boosts survival in biliary tract cancers
The combination of cisplatin (Platinol) and gemcitabine (Gemzar) helped patients with advanced, inoperable cancers of the biliary tract (gallbladder and bile duct) live several months longer than patients who received gemcitabine alone (11.7 versus 8.2 months), according to findings presented at the ASCO annual meeting. more
Breast cancer drug helps patients with gastric cancer
The breast cancer drug trastuzumab (Herceptin) has been shown to improve the survival of patients with advanced gastric cancer. The addition of trastuzumab to standard chemotherapy helped patients live longer than similar patients who received chemotherapy alone, researchers said at the ASCO annual meeting. more
HPV status can predict outcome in oropharyngeal cancer
Patients with advanced forms of a cancer in the upper portion of their throat have better outcomes if their tumors are positive for the human papillomavirus (HPV), according to new data from a phase III clinical trial presented at the ASCO annual meeting. Although other studies have suggested a link between HPV status and outcome in patients who have oropharyngeal cancer, these new data provide the most definitive evidence, said the studyís leader, Dr. Maura Gillison of Ohio State University, at a recent press briefing. more
Radiofrequency ablation effective against Barrett esophagus
About 10 percent of the 10 million adults in the United States who have chronic gastroesophageal reflux disease develop abnormal cell changes in the lining of their esophagus, a condition called Barrett esophagus (BE) that can lead to esophageal cancer. While 99 percent of adults with BE will not progress to cancer, their risk of developing esophageal cancer is still 100 times greater than that of the general population.
Treatment vaccines for cancer perform well in clinical trials
Treatment vaccines that boost the immune systemís response to tumors may have important clinical benefits for patients with various types of cancer, according to results from several clinical trials presented at the 2009 American Society of Clinical Oncology (ASCO) Annual Meeting in Orlando. more
Study reveals publics' ignorance of anatomy
A study of patients and members of the public has shown that most lack even basic knowledge of human anatomy. The research, featured in the open access journal BMC Family Practice, found that people were generally incapable of identifying the location of major organs, even if they were currently receiving relevant treatment. more
