Table 3 Multivariate Logistic
regression analysis of PD-L2 expression by clinicopathologic
characteristics
3, MG and PD-L2 expression,
clinicopathologic characteristics
Table 4 shows the compare of clinicopathologic characteristics between
MG (+) group and MG (-) group. The patients with WHO histology of type
B2 and B3 have a significantly higher incidence rate of MG (p=0.004).
The patients with MG have smaller tumor size (p<0.001) and
higher PD-L2 scores (p<0.001). No significantly difference
were observed in age (p=0.052), gender (p=0.224), Masaoka-Koga stage
(p=1) or ectopic thymus (p=0.357). Due to the positive association
between MG and PD-L2 expression, we particularly analyzed the data of
patients with MG to explore if the PD-L2 expression depended on the
different features of MG (Table 5). 33 patients with MG were enrolled.
There were no significantly difference of PD-L2 scores regarding gender,
age, MGFA stage, WHO histology type, Masaoka-Koga stage, tumor size or
ectopic thymus in patients with MG. We conducted a logistic
regression model to predict PD-L2 expression in
patients with MG. No feature listed above was associated with PD-L2
expression in patients with MG.
