“…CD69 expression on tumor cells was a poor prognostic sign, and an interfollicular infiltrate of FoxP3-positive T cells was a good prognostic sign irrespective of the treatment arm, and the authors suggest that a dense infiltrate of FoxP3-positive T cells, dense and interfollicular infiltrate of CD68-positive macrophages, and complete follicular dendritic meshworks were associated with a favorable time to progression in CVP-treated patients, while being a poor prognostic sign in fludarabine-treated patients. This finding confirms the importance of moving away from prognostic marker studies and go to predictive markers (van Krieken [ 4 ]). Ai et al [ 5 ] did in vivo experiments that partially explain the findings of de Jong et al: follicular lymphoma B cells in contrast to normal B cells could induce conventional T cells to express FoxP3 and to acquire regulatory function.…”
