Table 2. PKM2 immunostaining results of patients with lung adenocarcinoma.
Tissue type | Number | Male | Female | Positive rate | Intensity | Total staining Scorea, |
Adjacent normal tissues | 30 | 14 | 16 | 0.47±0.68 | 0.57±0.86 | 0.80±1.47 |
Well | 21 | 11 | 10 | 1.43±0.87 | 1.05±0.59 | 1.86±1.56 |
Moderately | 37 | 16 | 21 | 1.73±0.96 | 1.76±0.93 | 3.41±2.40 |
Poorly | 40 | 19 | 21 | 2.75±0.44 | 2.63±0.49 | 7.18±1.65 |
a: Total staining of PKM2 was scored as the product of the staining intensity (on a scale of 0–3) × the percentage of cells stained (on a scale of 0–3).
