Abstract

Objective: Papillary thyroid cancer (PTC) is the most common well-differentiated thyroid cancer. Lymph node (LN) metastasis is frequently seen in PTC. The effect of BRAFV600E mutation on PTC-associated LN metastasis has not been clearly established. Therefore, we aimed to evaluate the effect of the BRAFV600E mutation in patients with PTC on regional LN metastasis. Material and Methods: Between January 2013 and 2017, sixty-three PTC patients who underwent central lymph node dissection were included into the study. The patients were divided into two groups according to the pathology results of the LN dissection, and these groups were compared for positive BRAFV600E mutations and other clinicopathological findings.Results: BRAFV600E mutation was found to be more significant in the pLN1 group (p= 0.005). Multivariate analysis revealed that nodule size, microcalcifications, and BRAFV600E mutation were associated with lymph node metastasis independent of other parameters. ROC analysis also evaluated the adequacy of the BRAFV600E mutation in predicting the presence of LN involvement. AUC: 0.738 (95% CI: 0.6110.866, p: 0.002). Conclusion: In our study, independent of other parameters, BRAFV600E gene mutation was found to be effective on lymph node involvement.

Özet

Giriş ve Amaç: Papiller tiroid kanseri (PTK) iyi diferansiye tiroid kanserleri içinde en sık görülen tiptir. Lenf nodu (LN) metastazı PTK’de sıklıkla görülür. BRAFV600E mutasyonunun PTK ile ilişkili LN metastazı üzerindeki etkisi kesin olarak belirlenememiştir. Bu nedenle çalışmamızın amacı PTK’lihastalarda BRAFV600E mutasyonunun bölgesel LN metastazı üzerindeki etkisini değerlendirmektir. Gereç ve Yöntem: Ocak 2013-2017 arasında santral lenf nodu diseksiyonu yapılan 63 hasta çalışmaya dahil edildi. Hastalar LN diseksiyonununpatoloji sonuçlarına göre pLN0 ve pLN1 olmak üzere iki gruba ayrıldı. Gruplar BRAFV600E mutasyon varlığı açısından ve diğer klinikopatolojikbulgular ile karşılaştırıldı. Bulgular: BRAFV600E mutasyonu, pLN1 grubunda anlamlı yüksek saptandı. (p= 0,005). Yapılan çok değişkenli analizde nodül büyüklüğü, mikrokalsifikasyon ve BRAFV600E mutasyonunun diğer parametrelerden bağımsız olarak lenf nodu metastazı ile ilişkili olduğunu ortaya koyuldu. ROCanalizi ile BRAFV600E mutasyonunun LN tutulumunun varlığını öngörmedeki yeterliliği de anlamlı olarak saptandı [AUC: 0,738 (%95 CI: 0,61-0.86,p= 0,002)]. Sonuç: Çalışmamızda diğer parametrelerden bağımsız olarak BRAFV600E gen mutasyonunun lenf nodu tutulumu üzerinde etkili olduğu bulundu.
