- Follicular lymphoma (FL) constitutes a significant proportion of lymphomas and shows frequent relapses. Beyond conventional chemotherapy, new therapeutic approaches have emerged, focussing on the interplay between lymphoma cells and the microenvironment. Here we report the immunophenotypic investigation of the microenvironment of a clinically well-characterized prospective cohort (study SAKK35/10, NCT00544219) of 154 treatment-naive FL patients in need of therapy, who have been treated with rituximab only or a combination of rituximab and the immunomodulatory drug lenalidomide/Revlimid (R) A high ratio of CD4- to CD8-positive T cells (P = 0 center dot 009) and increased amounts of PD1(+) tumour-infiltrating T cells (P = 0 center dot 007) were associated with inferior progression-free survival in the whole cohort. Interestingly, the prognostic impact of PD1(+) T cells and the CD4/CD8 ratio lost its significance in the subgroup treated with R-2. In the latter group, high amounts of GATA3(+) T helper (Th2) equivalents were associated with better progression-free survival (P < 0 center dot 001). We identified tumour microenvironmental features that allow prognostic stratification with respect to immuno- and combined immuno- and immunomodulatory therapy.
