Does Tumor Burden Limit the Accuracy of Lymphatic Mapping and Sentinel Lymph Node Biopsy in Colorectal Cancer?

Abstract: Identification of the SLN in colorectal cancer is technically possible in more than 90% of patients. However, SLN status correlates poorly with the true nodal status of the colorectal cancer, and the false-negative rate is 50%. This high false-negative rate is not clearly explained by extensive tumor burden, and it was also independent of gender, tumor stage, and type of lymphatic mapping technique. However, staging accuracy was lower in patients who underwent left-sided colorectal resection. Further studies a… Show more

“…The mean number of SLN found per patient ranges from 1.5 [10] to 3.5 [18]. The figures of upstaging (0-24%) vary considerably among studies [10,14,17,[19][20][21][22][23][24]. All of this highlights the technical feasibility of the procedure and the potential advantages particularly for upstaging.…”

“…The vast majority of published trials of SLN mapping for colon carcinoma have used in vivo injection of dye alone, typically isosulfan blue [8][9][10][11][12][13][14][15][16].…”

“…It is particularly important since there is a possibility that patients initially diagnosed as clinical stage II (having no metastases to the lymph nodes) might be up-staged to stage III (those who have metastases present in the lymph nodes) and thus be qualified for adjuvant chemotherapy. Summary of the SLNB studies in CRC is presented in the Table 4 [7,20,21,[26][27][28][29][30][31][32][33].…”

“…Es gibt überzeugende Daten, die nahe legen, dass die Anwendung dieser Ultrauntersuchungstechniken bei allen Knoten eines Kolektomiepräparats einen bestimmten Anteil von Patienten von lymphknotennegativ (Stadium I-II) auf lymphknotenpositiv (Stadium III) hochstufen [16,17] und im Vergleich zur histologischen Untersuchung mittels Hämatoxylin-Eosin-(HE-)Färbung die Erkennungsrate metastatischer Läsionen bei "Wächter-"Knoten erhöhen wird [12,13,18]. Weniger klar ist, ob die Entdeckung von Mikrometastasen prognostische Bedeutung hat [19] [2][3][4], die in diesen Studien entnommenen "Wächter"-Knoten anders als sonstige Lymphknoten im Präparat verarbeitet, was die Ergebnisse in Richtung Erfolg des SLN-Mappings beeinflusst [5][6][7][8][9][10][11][12][13][14][15]. Viele Untersucher wenden bei "Wächter-"Knoten hochentwinegative and nonsentinel nodes were positive in 9 of 38 patients (24 percent).…”

“…Zusätzlich haben jüngste Daten darauf hingewiesen, dass die Zugabe radioaktiver Stoffe zur Färbelösung die Ausbeute während des SLN-Mappings im Kolon mitunter nicht verbessert [15]. Folglich wurde in der Mehrzahl der veröffentlichten Studien über SLN-Mapping bei Kolonkarzinom die In-vivo-Injektion ausschließlich von Farbstoff verwendet, typischerweise Isosulfanblau [2,4,6,7,10,11,14,20,21].…”
