Diagnostik des »Sentinel Lymph Node« bei malignem Melanom: präoperative Lymphszintigraphie und intraoperative Sondenmessung

Abstract: Zusammenfassung Ziel: Der »sentinel lymph node« (SLN) reflektiert den Befall der nachfolgenden Lymphknoten-Stationen bei Patienten mit malignem Melanom und hat damit eine erhebliche prognostische Bedeutung. Ziel der Studie war die prä- und intraoperative Lokalisierung dieses Lymphknotens mittels Lymphszintigraphie und Sondenmessung. Methoden: 38 Patienten mit malignem Melanom (Tiefenausdehnung >0,75 mm) wurden nach Injektion von 40 MBq 99Tc-Nanocoll szintigraphisch untersucht. Die Position des ers… Show more

“…It has a wide irregular size and (20) found major variations in the radiochemical purity and particle size distribution of sulfur colloid depending on labeling conditions. The sentinel lymph node-positive rate was 22%, compared with 18% to 25% using nonocolloids, as published previously (2)(3)(4). According to a European questionnaire, 80% of 40 institutions were using Tc-99m nanocolloid as the radiopharmaceutical in patients with melanoma (27).…”

“…The sentinel lymph node has been shown to reflect the histologic features of the entire lymphatic basin in patients with melanoma (2). Therefore, the sentinel lymph node is of considerable prognostic value, because extensive lymph node dissection may not be necessary in patients who have histologically negative sentinel lymph nodes (3,4). Lymphoscintigraphy is based on the physiologic transport of radiotracers, and thus the radiopharmaceutical should first identify the sentinel lymph node and remain in part trapped therein, before traveling to nonsentinel lymph nodes (1,5).…”

“…Conclusion: 99m Tc-bound colloidal rhenium sulphide is also suitable for sentinel node mapping. ist der SLN von entscheidender prognostischer Bedeutung, da eine extensive Lymphknotenexstirpation bei Patienten mit histologisch unauffälligem SLN nicht erforderlich ist (11,30).…”

“…* Beispiel: D-III B (Leiste rechts: #1: -, Axilla rechts: #2: -; #3: mol+; Leiste links: #4: mi+). gemäß dem Postulat des Konzepts auch die non-Sentinel-Lymphknoten in derselben Lymphknotengruppe tumorfrei [33,48]. Es ist zu beachten, dass situationsbedingt lediglich das Drainagemuster der Injektionsstelle ("Tumorlokalisation", TL; prä-OP oder post-OP), mithin der/die Sentinel-Lymphknoten des/der Injektionsdepots erfasst wird/werden.…”
