MCAM and neoplasm: Using the data from Shih et al. [11] we found that if the tumor volume was calculated using our ellipsoid equation [19], the mean final tumor volume from their vector control clone would have been ~27 ± 7.5 mm3, which was about two times larger than our corresponding control clone (14.1 mm3), and that from their METCAM-expressing clone would have been ~3.5 ± 2.6 mm3, which was similar to our corresponding clone (~4.6 ± 3.1 mm3).
