Table 4 The comparison of tumor characteristics of acinary and solid adenocarcinomas

From: The correlation of SUVmax with pathological characteristics of primary tumor and the value of Tumor/ Lymph node SUVmax ratio for predicting metastasis to lymph nodes in resected NSCLC patients

  Acinary (n = 16) Solid (n = 9) p
Tumor diameter (cm) (mean ± SD) 4.7 ± 1.8 6.8 ± 2.1 0.014*
Tumor SUVmax (mean ± SD) 12.9 ± 7.5 16.7 ± 8.1 0.21
Number of mitosis (mean ± SD) 12.8 ± 7.1 26.7 ± 15.4 0.018*
Necrosis (median) 1 2 0.002*
Stromal inflammation (median) 2 2 0.48
Tumor SUVmax/Tumor diameter¥ (mean ± SD) 2.90 ± 1.49 2.63 ± 1.44 0.73
  1. *Statistically significant.
  2. ¥ In order to eliminate the effect of tumor diameter on the SUVmax values, we compare the tumor SUVmax value/ tumor diameter ratios.
