Tumoral lymphocyte immune response to preoperative radiotherapy in locally advanced rectal cancer as a prognostic factor for survival: the LYMPHOREC …
2015
Présentation Poster; International audience; Background: Short-course preoperative radiotherapy (sc-preopRT) and long-course preoperative radiotherapy (lc-preopRT) followed by total mesorectal excision (TME) are worldwide standards of care in locally advanced T3–4 N0 or N1 rectal adenocarcinoma. It is now well established that the host immune system participates in the elimination of tumor cells and that significant tumor infiltration by T-cells (LT), such as CD8+, is associated with a better prognosis. In colorectal tumors, the infiltration of Treg FoxP3+ is also described as a prognostic factor associated with better survival. We aimed to investigate the impact of the immune response to p…
Aspects fonctionnels et pronostiques des cellules myéloïdes suppressives et de Foxp3 dans le cancer
2011
Evasion of immune surveillance by certain tumour cells seems to be a basic requirement for tumour development in preclinical models and in humans. The mechanisms by which the tumour mediates its immune evasion are manifold, and involve the majority of immune system cells. Among these, immunoregulatory cells such as myeloid-derived suppressor cells (MDSCs) or regulatory T lymphocytes (T-regs, which express the transcription factor Foxp3) appear to play a predominant role. The results presented in this work aim to improve our understanding of the functional and prognostic roles of myeloid suppressor cells and T-regs in cancer, focussing particularly on how these cells are modulated by chemoth…
