Abstract

Aim: Although there are clinical differences in colon cancer (CC) according to the location of the tumor, the differences between right and left CC in terms of survival are not clear. Our aim was to analyze the clinicopathological differences between right and left CC and to investigate the effect of primary tumor location on recurrence and survival.Method: The data of 330 patients who underwent curative surgery for right (n=155) or left (n=175) colon cancer between 2011 and 2018 were retrospectively analyzed. Demographic characteristics, surgical data, pathological data, recurrence and survival rates of the patients were examined and the two groups were compared in terms of these parameters.Results: Male to female ratio was significantly higher and operative time was significantly longer in the left CC than in the right CC. The mean number of harvested lymph nodes was significantly higher in the right CC than the left CC (32±3 and 27±9, respectively, p=0.001). Compared to patients with left CC, those with right CC had higher tumor diameter and tumor volume, had more poorly differentiation and tended to have more mucinous and medullary type cancer. As a result of a median follow-up of 54 months, it was determined that the 5-year overall survival in stage I-III patients was worse in the right CC than in the left CC. Especially in stage III patients, both overall and disease-free survival rates were found to be statistically significantly lower in the right CC compared to the left CC (In stage III disease, overall survival was 66.9% in right CC and 81.8% in left CC, p=0.03; disease-free survival was 54.2% in right CC and 70.6% in left CC, p=0.04).Conclusion: There may be clinicopathological and prognostic differences in CC depending on the location of the tumor. As a result of the long followup period in our case series, the prognosis in the right CC was worse, especially in stage III patients.sağkalım oranının sağ KK’sinde sol KK’sine göre istatiktiksel olarak anlamlı derecede düşük olduğu tespit edildi (Evre 3 genel sağkalım: sağ %66,9 ve sol %81,8, p=0,03; evre 3 hastalıksız sağkalım: sağ %54,2 ve sol %70,6, p=0,04).Sonuç: Kolon kanserinde tümörün yerleşim yerine göre klinikopatolojik ve prognostik farklılıklar olabilir. Kendi serimizdeki uzun takip süresi sonucunda, sağ KK’sinde prognoz özellikle evre 3 hastalarda daha kötü seyretmektedir

Özet

Amaç: Kolon kanserinde (KK) tümörün yerleşim yerine göre klinik farklar görülmesine rağmen sağkalım açısından sağ ve sol KK arasındakideğişiklikler tam olarak netlik kazanmamıştır. Amacımız; sağ ve sol KK’si arasındaki klinikopatolojik farklılıkları analiz etmek ve primer tümöryerleşiminin nükse ve sağkalıma etkisini araştırmaktır. Yöntem: 2011-2018 tarihleri arasında, sağ (n=155) veya sol (n=175) kolon kanseri tanısıyla küratif cerrahi uygulanan 330 hastanın verileri retrospektifolarak incelendi. Hastaların demografik özellikleri, ameliyat verileri, patolojik verileri, nüks ve sağkalım oranları incelendi ve iki grup arasındakarşılaştırmalar yapıldı. Bulgular: Sol KK’sinde erkek/kadın oranı ve ameliyat süresi sağ KK’sine göre anlamlı derecede yüksekti. Çıkarılan ortalama lenf nodu sayısı sağKK’inde sol KK’sine göre anlamlı derecede fazlaydı (32±3 ve 27±9 sırasıyla, p=0,001). Ayrıca sağ KK’sinde tümör çapı ve tümör hacmi daha fazla, azdiferansiyasyon oranı, müsinöz ve medüller kanser oranı sol KK’sine göre istatistiksel olarak anlamlı derecede daha yüksekti. Ortanca 54 ay takipsonucunda, evre 1-3 hastalarda 5 yıllık genel sağkalımın sağ KK’sinde daha kötü seyrettiği özellikle evre 3 hastalarda hem genel hem de hastalıksız
