Research published in the September 2009 issue of the Journal of Thoracic Oncology has found that an individual's quality of life prior to treatment can help predict the overall survival of patients with advanced stage non-small cell lung cancer (NSCLC).
For those with advanced stage NSCLC, the median overall survival varies between six and 12 months, with approximately one-third of patients surviving past the one year mark. To better understand the factors that predict the overall survival of patients with NSCLC, various research has been done in the past to determine whether or not pretreatment quality of life can help predict overall survival, but yielding conflicting results. To provide a more definitive answer on this question, Yingwei Qi, M.D., M.S., of the Mayo Clinic Rochester in Minnesota, and a team of researchers conducted a pooled analysis of research from six different clinical trials, representing 420 patients overall.
