Change in lung tumor volume as a biomarker of treatment response: a critical review of the evidence

P. D. Mozley, L. H. Schwartz, C. Bendtsen, B. Zhao, N. Petrick, A. J. Buckler
2010 Annals of Oncology  
Conclusion: The weight of the evidence indicates there are circumstances in which volumetric image analysis adds value to clinical trial science and the practice of medicine.  ...  Measurement error still makes the assessment of change in small nodules precarious in diagnostic settings unless rigorous image acquisition and analysis procedures are followed.  ...  In a sample of 35 patients with early-stage lung cancer, they found that 30 of 35 (85.7%) subjects treated with pazopanib had a measurable decrease in tumor volume, while only three of these 35 subjects  ...
