TLDR
It is suggestive 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 poor prognostic sign in fludarabine- treated patients.Abstract:
Background The clinical behavior of follicular lymphoma is largely determined by properties of the non-malignant tumor microenvironment. The precise nature of the cell populations is still unclear and published data on their prognostic significance are highly conflicting. This may be partly due to heterogeneous composition and tr eatments. Design and Methods Pre-treatment biopsy samples of patients with follicular lymphoma treated in an EORTC/BNLI trial comparing fludarabine to cyclophosphamide, vincristine and prednisone (CVP) chemotherapy could be retrieved for 61 patients in five Eur opean countries. Immunohistochemical investigations were performed to evaluate tumor cell characteristics, T-cell subsets, follicular dendritic cells and macrophages and associations with clinical outcome were studied. Results Some markers showed a homogeneous prognostic impact, while others had a different and sometimes opposite effect in the treatment arms. 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. It is suggestive that a dense infiltrate of FoxP3-positive T cells, a dense and interfollicular infiltrate of CD68-positive macr ophages 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. Conclusions Our results suggest that characteristic properties of the microenvironment in follicular lymphoma determines the responses to essentially different chemotherapeutic approaches. These data may provide an explanation for the highly conflicting r esults on immunohistochemical markers and the prognostic role of the microenvironment in follicular lymphoma reported thus far and lay the basis for the development of predictive assays to tailor treatment in patients with follicular lymphoma.read more

Predictors for cancer treatment
TL;DR: In this article, the authors proposed methods of predicting a response to a cancer treatment by determining CD68 level or PSMBl (PI 1A) polymorphism in a biological sample and the presence or quantity of a second biomarker in the patient.

TL;DR: The population of CD4+CD25+ immunoregulatory cells is characterized and it is demonstrated that they can suppress not only the induction of disease post-thymectomy, but can also efficiently suppress disease induced by cloned autoantigen-specific effector cells.
