Breslow depth and ulceration of a primary tumour can have a significant impact on the survival time of a patient
The number of lymph nodes containing melanoma is a useful and accurate prognostic factor in predicting survival, as documented in a landmark study by Balch et al in 2001.
The staging of melanoma makes use of a number of systems to assess the depth of a tumour. From this, likelihood of spread and survival prognosis can be determined. Our guide explains the methods used.
