Abstract

Between August 2003 and September 2008, 20 patients with cutaneous malignant melanoma (9 males and 11 females, average age 54.8) underwent sentinel node (SN) biopsy using a combination of the blue dye method and lymphscintigraphy with a gamma probe. We identified SN in 19 of the 20 patients (95.0%), but we did not identify SN in one case after the tumor had been already been removed surgically in another clinic. The average SN number was 2.3. SN metastases were detected in 7 patients (36.8%), and all the SN positive patients underwent regional lymph node (LN) dissection. In 6 patients (31.6%), we detected SN in multiple fields. The average tumor thickness for SN negative patients was 3.6 mm, and the average tumor thickness for SN positive patients was 6.0 mm. The SN metastasis rates due to T classification were 0% in T1, 25.0% in T2, and 55.6% in T3 and T4. Multi-center clinical trials of SN biopsy with the use of blue dye and radiocolloid are warranted.
