TABLE 1.

Correlation Between Primary Tumor (PT) and Lymph Node (LN) Pathological Regression Grades

PT Regression Grade
I II III IV Total
Total LN regression grade I 89 15 8 3 115 (36.1%)
II 38 6 5 2 51 (16.0%)
III 35 8 10 5 58 (18.2%)
IV 37 18 17 23 95 (30.0%)
Total 199 (62.4%) 47 (14.7%) 40 (12.5%) 33 (10.3%) 319 (100%)

Bold numbers surrounded with bold squares indicate patients in whom the total LN regression grade coincided with the PT regression grade. Shaded cells indicate “responders” in terms of PT or total LN regression grade.

Patients in whom the total LN regression grade was better than the PT regression grade.

Patients in whom the total LN regression grade was worse than the PT regression grade.
