To examine the correlation of the quantitative indexes standardized uptake value (SUV), SUV corrected for lean body mass (SUL) and SUV corrected for Japanese lean body mass (SULj) with body weight to develop an appropriate quantitative index independent of body weight fluctuation for assessment of response to cancer treatment in Japanese patients.Fifty-six males with esophageal cancer and 30 females with breast cancer underwent fluorine-18-fluoro-2-deoxy-D-glucose (Analyses were conducted with all patients (P0.01), as well as after dividing into those with only esophageal (P0.05) or breast (P0.01) cancer. Regarding the correlation coefficient between each index and body weight, a significant difference was seen for SUVmax, SUVpeak and SUVmean. In contrast, there was no correlation with body weight for SULmax, SULpeak, SULmean, SULjmax, SULjpeak, or SULjmean in any of the 3 groups.Based on the correlation with body weight, we concluded that both SUL and SULj (SUL corrected for Japanese lean body mass) is useful for assessment of cancer treatment response in Japanese patients. |
