• The purpose of this retrospective study was to examine the relationship between tumor volume and age in resected nonsmall cell lung cancer (NSCLC). Differences exist in the behavior, growth rate, and metastatic potential of solid tumors in both aged humans and experimental animal models. Data from 669 cases of NSCLC resected between 1980 and 1992 were reviewed (445 males; 224 females; median age 67 years, range 16–86). Measurements of the resected tumor in-situ were made in three dimensions, and these were multiplied to give an estimate of the tumor volume. Multiple regression analysis was used to examine the relationship between the tumor volume, age, gender, histological cell type, and TNM nodal score. No direct relationship existed between patient age and tumor volume or nodal score. However, there was a significant relationship between patient gender and tumor volume, i.e., smaller volume tumors in female patients (p = .02). Considering all variables, two relational subgroups were identified: younger male patients with large adenocarcinomas and older female patients with small squamous cell carcinomas (p = .05). We conclude that the relationship between tumor volume and age is complex and dependent on patient gender and tumor cell type.
