Abstract

Aim: Sentinel lymph node biopsy (SLNB) in breast cancer patients targets the evaluation of the initial lymph node (SLN) which drains the primary tumor. The morbidity of unnecessary axillary dissection can be avoided by intensive preoperative assessment of SLN. Methods: Twenty-six consecutive patients who had been surgically treated for early-stage breast cancer between March 2005 and August 2007 were evaluated. Blue dye (methylene blue) method was used to detect SLN. All patients underwent axillary lymph node dissection following SLNB. NCSS program was used for statistical analysis. Chi-square test was used in the comparison of binary groups. Results: Except for one, all patients were female. The mean age of the patients was 56 (29-76) years. While 13 patients underwent modified radical mastectomy (=mastectomy+axillary dissection), the remaining 13 patients underwent breast preserving surgery (lumpectomy+axillary dissection). SLN could not be found in 2 patients (7.6%).The male patient was one of these 2 patients and both of them were positive for axillary node metastases. The detection rate of SLN, specificity, negative predictive value, positive predictive value, sensitivity, false negativity, and reliability were 92.3%, 92.8%, 86%, 90.9%, 83.3%, 16.6%, and 88.4%, respectively. Conclusion: Our result support the hypothesis that SLNB with blue dye alone is a reliable technique and, surgery clinics should use it prior to axillary dissection to test their own success during the learning curve.

Özet

Amaç: Meme kanserinde sentinel lenf nodu biyopsisi (SLNB), primer tümörü drene eden muhtemelen tümör hücresi içeren ilk aksil-ler lenf nodunu incelemeyi hedeflemektedir. Bu lenf nodunun (SLN) peroperatif olarak normalden daha yoğun çalışılması, gereksiz aksil-la diseksiyonunun morbiditesinden kaçınılmasını sağlamaktadır. Yöntemler: Mart 2005 ile Ağustos 2007 tarihleri arasında Genel Cerrahi Meme Hastalıkları Polikliniğimizde erken evre meme kanseri tanısı ile cerrahi yöntemle tedavi ettiğimiz ardışık 26 hasta araştırılmıştır. SLN saptanmasında mavi boya (metilen mavisi) yöntemi kullanılmıştır. Tüm hastalara SLN biyopsisini takiben aynı seansta aksiller lenf nodu diseksiyonu yapılmıştır. istatistik analiz, NCSS 2007 paket programı ile yapılmıştır. ikili grupların karşılaştırılmasında ki-kare testi kullanılmıştır. Bulgular: 26 hastanın 25'i kadın 1'i erkek idi. Hastaların yaş ortalaması 56 (29-76) yıl idi. 13 hastaya modifiye radikal mastektomi (=mastektomi+aksiller küretaj) uygulanırken, 13 hastaya meme koruyucu ameliyat (lumpektomi+aksiller küretaj) uygulandı. 26 hastanın 2'sinde (%7.6) SLN tespit edilemedi. Erkek meme kanseri vakası da bu gruba dahildi ve bu iki hastanın da aksillasında kar-sinom metastazı bulundu. SLN bulma oranımız %92.3, özgüllük %92.8, negatif tahmin değeri %86, pozitif tahmin değeri %90.9, duyarlılık %83.3, yalancı negatiflik %16.6, doğruluk %88.4 idi. Sonuç: Salt mavi boya ile SLNB hipotezi doğru bir varsayıma dayanmaktadır ve öğrenme eğrisi sırasında SLNB uygulanan hastalara buna rağmen eş zamanlı aksiller diseksiyon da yapılarak kliniklerin kendi başarılarını test etmeleri gerekmektedir.
