From: PD-L1 expression is associated with ALK positivity and STAT3 activation, but not outcome in patients with systemic anaplastic large cell lymphoma

Correlation between PD-L1 expression and pSTAT3 in anaplastic large cell lymphoma. a The percentage of pSTAT3+ lymphoma cells in ALK+ anaplastic large cell lymphoma was higher than that in ALK-negative anaplastic large cell lymphoma. b, c, The percentage of PD-L1+ lymphoma cells was correlated with the percentage of pSTAT3+ lymphoma cells, weakly (b, r = 0.4) in ALK+ but strongly (c, r = 0.8) in ALK-negative anaplastic large cell lymphoma. d–i representative pictures showing the correlation between PD-L1 and pSTAT3 (d–f PD-L1 immunohistochemistry, ×400; g–i, pSTAT3 immunohistochemistry, ×400)
