[Immunoscintigraphy with 99mTc marked melanoma antibody in patients with malignant melanoma]
In 38 patients with malignant melanoma 44 radioimmunoscintigraphies (RIS) with 99mTc labeled F(ab')2 fragments of an anti-melanoma monoclonal antibody (225.28S, Tecnemab-K, Sorin Biomedica) have been performed. No side effects have been observed even in the patients with repeated RIS. Overall 81% (35/43) of all lesions were detected by imaging and 9 lesions have been previously unknown. Sensitivity and specificity was highest for lymphnode metastases with 100% each. Poor imaging was observed in lung and mediastinal metastases (2/7) as well as small skin metastases. RIS has to be studied for its clinical value in staging of lymphnode metastases preoperatively in patients undergoing regional lymphnode dissection.
