Immune profiling of lymph nodes associated with cancer

摘要

Cancers are phenotyped by analysis of the presence of immune cells, particularly T cells and dendritic cells, present in regional lymph nodes. When non-sentinel regional lymph nodes of a cancer patient are compared to normal lymph nodes, it is found that increased number of dendritic cells and decreased numbers of T cells, particularly T helper cells, correlate with a positive prognosis and disease-free survival following conventional chemotherapy.
