	Quasi-mesenchymal (KRT81+)	Exocrine-like (HNF1A+)	Classical (double negative)
M1-PUL, n (%)	11 (29)	8 (21)	19 (50)
M1-ANY (control^b), n (%)	8 (24)	5 (15)	20 (61)

Chi-square test: P = 0.707.

M1-PUL, pulmonary metastasis; M1-ANY, any metastases excluding lung-only involvement.

Staining technically successful for 38 of 47 PDAC samples from M1-PUL patients and 33 of 47 control samples.
