Abstract

Correct determination of lymphatic nodal statement is essential to stage correctly and to predict survival. As it is vital to make an assessment about the adjacent lymph node(s), this study was designed to compose a sensitive detection on the sentinel lymph nodes (SLN) indicating tumoral lymphatic basin using advanced pathologic examination. Materials and Methods: From June 2002 to June 2003, this prospective study was performed in 41 patients undergoing standard resection for colorectal cancer. In this study we employed the ex-vivo SLN mapping technique. Results: At least one SLN in 37 of 41 patients was identified (90.2%). The lymph nodes (LN) from those patients were studied by hematoxylin and eosin dye (H&E) and multisectioning. Twenty of 37 patients with trace of the metastasis were found. The remaining 17 patients without any metastatic LN by H&E underwent clarification of micrometastases (MM) using immunohistochemical (IHC) staining technique. Two patients (11.7%) had MM in the SLN(s). Upstaging was evaluated in those two. The sensitivity of SLNs was obtained as 90%. Two patients with no metastatic SLN had metastasis in the non-sentinel LNs. Conclusions: In the LNs from the basin of tumor, MM exposed by IHC staining was still not obvious to indicate poor prognosis. The need for treatment adjustment in those patients is clear since the upstaging was evident.

Özet

Kolorektal kanserlerde lenfatik tutulumun ortaya konması hem doğru evreleme hemde sağ kalım hakkında karar vermek için gereklidir. Tümor hücrelerinin drene olduğu ilk lenf nodu olan sentinel lenf nod(lar)unun (SLN) belirlenip, ileri patolojik teknik ile değerlendirilmesinin önemli olduğu bilinerek bu çalışma yapıldı. Yöntem: Haziran 2002-2003 arasında prospektif çalışmaya 41 hasta alındı. Kolorektal kanser tanısı olan bütün hastalara standart cerrahi tedavi uygulandıktan sonra "exvivo" yöntem ile SLNharitalaması yapıldı. Bulgular: Hastaların 37’sinde (%90.2) SLN’u bulundu. Lenf nodları hematoksilen-eozin boyası ve çoklu kesit alma işlemleri ile değerlendirildi. Otuzyedi hastanın 20’sinde metastaz bulundu. Geri kalan 17 hastaya immünohistokimyasal boyama uygulanarak metastaz ve/veya Mikrometastaz (MM) araştırıldı. Ik hastada (%11.7) MM bulundu. Bu hastalarda SLN’nda metastaz olmadığı halde tumoral yatak lenf nodlarında metastaz olduğu için evre yükselmesi olarak değerlendirildi. SLN haritalaması % 90 oranında bir duyarlılıkla tumoral yatağın durumunu gösterdi. SLN’nda metastaz olmayan 20 hastanın 2 sinde de diğer lenf nodlarında metastaz tespit edildi (yanlış negatiflik %10). Sonuç: Erken ever kolorektal kanserli hastalarda tumor yatağındaki lenf nodlarında MM’ın ortaya konulması kötü prognozu kesin olarak belirtmese bile evre yükselmesi ve buna bağlı olarak kemoterapi tedavisi yapılması gerekliliği açıktır.
