ABSTRACT
Several different protocols for retrieval of the sentinel node (SN) have been described gamma probe (GP) and/or dye guided biopsy, preceded by lymphoscintigraphy or not. Especially in American studies, predominantly executed by surgeons, dye or GP guidance only is used with good results. The disadvantages of applying dye only are an extensive learning curve, lower retrieval rate of the SN and, especially in the learning phase, a higher rate of false negative biopsies. If only GP guidance is applied, the technique seems more simple to master. A recent multicentre study, however, revealed an unacceptably high false negative rate. It must be considered that most published studies were executed by highly experienced surgeons. In most European studies, scintigraphy is a standard part of the procedure. Lymphoscintigraphy provides the surgeon with a "road map", revealing the number and approximate location of the SNs in the lymphatic basin(s). Scintigraphy proves useful especially if an SN is situated close to the injection site (breast cancer), or if SNs are situated at unexpected locations (head-and-neck or trunk melanoma). A combination of all three available steps results in the highest number of successful procedures with the lowest false negative rate. This may prove to be especially important for general hospitals where the number of biopsy procedures is often smaller compared to specialized centres.
