The patients were divided into two groups: the skip metastasis group (sN2) (group 1, n=55) [N1(-), N2(+)] and non-skip ipsilateral mediastinal lymph node metastasis group (nsN2) (group 2, n=56) [N1(+), N2(+)].Results: The median survival was 25 months and five-year overall survival rate was 13% for both study groups.

📌 3 Key Takeaways

🎯
Objective & Hypothesis:Background: This study aims to examine skip metastases in patients who had resection due to non-small cell lung cancer.Methods: A total of 111 patients (94 males, 17 females;mean age: 58.9±10.2 years; range 35 to 82 years) who were diagnosed with non-small cell lung cancer and in whom an ipsilateral mediastinal lymph node metastasis was detected based on the pathological examination of the R0 pulmonary resection samples between January 2005 and December 2011 in our clinic were retrospectively analyzed.
📊
Key Findings & Data:The patients were divided into two groups: the skip metastasis group (sN2) (group 1, n=55) [N1(-), N2(+)] and non-skip ipsilateral mediastinal lymph node metastasis group (nsN2) (group 2, n=56) [N1(+), N2(+)].Results: The median survival was 25 months and five-year overall survival rate was 13% for both study groups.
💡
Conclusion & Impact:Five -year overall survival rate was higher in group 1, compared to group 2 (20% vs. 7.4%, respectively), although the difference was not statistically significant (p=0.084).Conclusion: Our study results show that five-year overall survival rates of operable patients with skip metastases are higher than those without skip metastases, although the difference is not statistically significant.

Abstract

Background: This study aims to examine skip metastases in patients who had resection due to non-small cell lung cancer.Methods: A total of 111 patients (94 males, 17 females;mean age: 58.9±10.2 years; range 35 to 82 years) who were diagnosed with non-small cell lung cancer and in whom an ipsilateral mediastinal lymph node metastasis was detected based on the pathological examination of the R0 pulmonary resection samples between January 2005 and December 2011 in our clinic were retrospectively analyzed. The patients were divided into two groups: the skip metastasis group (sN2) (group 1, n=55) [N1(-), N2(+)] and non-skip ipsilateral mediastinal lymph node metastasis group (nsN2) (group 2, n=56) [N1(+), N2(+)].Results: The median survival was 25 months and five-year overall survival rate was 13% for both study groups. Five -year overall survival rate was higher in group 1, compared to group 2 (20% vs. 7.4%, respectively), although the difference was not statistically significant (p=0.084).Conclusion: Our study results show that five-year overall survival rates of operable patients with skip metastases are higher than those without skip metastases, although the difference is not statistically significant.

Özet

Amaç: Bu çalışmada küçük hücreli dışı akciğer kanseri nedeni ile rezeksiyon yapılan hastalarda skip metastazları incelendi. Çalış­ma­ planı:­ Kliniğimizde Ocak 2005 - Aralık 2011 tarihleri arasında küçük hücreli dışı akciğer kanseri tanısı konan ve R0 akciğer rezeksiyonu örneklerinin patolojik incelemesi sonucunda aynı taraf mediastinal lenf nodu metastazı saptanan toplam 111 hasta (94 erkek, 17 kadın; ort. yaş: 58.9±10.2 yıl; dağılım 35 -82 yıl) retrospektif olarak incelendi. Hastalar skip metastazlı grup (sN2) (grup 1, n=55) [N1(-), N2(+)] ve skip metastazı olmayan aynı taraf mediastinal lenf nodu metastazlı grup (nsN2) (grup 2, n=56) [N1(+), N2(+)] olmak üzere iki gruba ayrıldı. Bulgu­lar:­ Her iki çalışma grubunda medyan sağkalım 25 ay olup, beş yıllık genel sağkalım oranı %13 idi. Beş yıllık genel sağkalım oranı grup 2’ye kıyasla grup 1’de daha yüksek olmakla birlikte (sırasıyla %7.4’e karşın %20), fark istatistiksel olarak anlamlı değildi (p=0.084). Sonuç:­ Çalışma sonuçlarımız istatistiksel olarak anlamlı bir fark olmasa da skip metastazı olmayan hastalara kıyasla, skip metastazlı ameliyat edilebilir hastalarda beş yıllık genel sağkalım oranının daha yüksek olduğunu göstermektedir.
