Table 3 The comparison of tumor characteristics of adenocarcinomas and squamous cell carcinomas

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

  Adenocarcinoma (n = 32) Squamous cell Ca (n = 43) p
Tumor diameter (cm) (mean ± SD) 4.9 ± 2.2 4.7 ± 1.6 0.93
Tumor SUVmax (mean ± SD) 12.6 ± 8.3 15 ± 5.9 0.042*
Number of mitosis (mean ± SD) 16.12 ± 12.03 31.5 ± 18.0 <0.001*
Necrosis (median) 1 2 0.24
Stromal inflammation (median) 2 2 0.08
Tumor SUVmax/Tumor diameterÞ (mean ± SD) 2.64 ± 1.52 3.50 ± 1.71 0.006*
  1. *Statistically significant.
  2. Þ In order to eliminate the effect of tumor diameter on the SUVmax values, we compare the tumor SUVmax value/ tumor diameter ratios.
