Extrafollicular PD1 and Intrafollicular CD3 Expression Are Associated With Survival in Follicular Lymphoma

This study aimed to stratify follicular lymphoma (FL) patients' outcome according to immunohistochemical parameters. The study correlated Ki-67, CD68, PD1 and CD3 results with clinical outcome. We found that high extrafollicular PD1 and low intrafollicular CD3 correlated with better outcome. Further studies are necessary in order to understand the complexity of the tumor microenvironment and its association with FL outcome.
