Serum Biomarkers May Prognosticate Recurrence in Node-Negative, Non-Small Cell Lung Cancers Less Than 4 Centimeters

In this single institution study, the authors screened biorepository materials obtained from patients undergoing resection for early stage cancer.  They wished to identify serum markers related to early recurrence.   A 7-component panel was developed that had a negative predictive value of 83% and an accuracy of  78%.  The accuracy was 70%.
