Accurate tumor measurement is essential in initial assessment of solid tumors. Furthermore, it is vital when evaluating treatment response. Change in tumor size determines whether a treatment course is effective, if treatment should be prolonged, or whether a more aggressive treatment or chemotherapy drug should be administered. Currently endorsed and widely used guidelines for tumor volume measurement include response evaluation criteria in solid tumors (RECIST), a one dimensional measure (cm) of target lesions which is not routinely the longest axis; World Health Organization (WHO), a 2 dimensional measure of the long and one short tumor axis (cm2) but is not a measure of volume; and Childrens Oncology Group (COG), a 3 dimensional ‘volume’ (cm3) measurement but does not account for shape of the tumor. Pediatric oncology patients are almost exclusively cared for in major academic or community hospital settings where modern CT and MR scanners routinely produce direct or reconstructed multiplanar images. Therefore an evolution of tumor measurement, to determine tumor volume, must be forthcoming. Read More
