Pathological stage was undetermined in 4 patients.
According to the American Joint Committee on Cancer classification. Equal variance, Fisher's least significant difference test:
Stage 3 vs. stage 1
stage 1 vs. stage 2
stage 2 vs. stage 3
Lymph node status was undetermined in 2 patients.
patients in the ≤40-year-old group compared with patients in the ≥56-year-old group
patients in the ≤40-year-old group compared with patients in the 41–56 years old group
patients in the 41–56-year-old compared with patients in the ≥56-year-old group. IOD, integrated optical density; SD, standard deviation.
