Our nomogram only utilizes routine predictors that are commonly available based on patient and primary tumor characteristics. Because the indications for sentinel lymph node biopsy in melanoma are not universally agreed upon, especially for very thin or very thick lesions, the nomogram alone is not a substitute for a consultation with your doctor. The nomogram predicts the probability of sentinel node involvement, but the threshold prompting sentinel lymph node biopsy should be decided between an individual patient and his or her physician.
