[The role of lymphography in melanoma of the limbs. Personal experience].

The authors report the results of the lymphographic examinations performed on 123 patients affected with melanoma of the limbs. The patients were divided into 2 groups according to the different clinical stages; they all had pathologic confirmation. The following lymphographic parameters were considered: sensitivity, specificity, efficacy and positive/negative predictive value. The results obtained in the first group of patients (clinical stage: I) demonstrated lymphography to have low sensitivity, specificity and efficacy in the staging of melanomas (37%, 50% and 45%, respectively). On the contrary, lymphography could be trusted in the study of stage II melanomas thanks to its high sensitivity. As for stage III, the methodology had a clinical indication only in the follow-up of melanomas treated with radiochemotherapy.
