The Number of Tumor Cells Spread to Sentinel Lymph Nodes Affects Melanoma Prognosis | Melanoma Dispatch |
Cancer cell spread to the sentinel node -- the lymph node to which cancer cells are most likely to spread from a primary tumor -- is a risk factor for melanoma death. The prognosis of a patient largely depends on the number of disseminated cancer cells per million lymphocytes in the sentinel node. Even very low numbers were found to be predictive for reduced survival.
