Abstract

Aim: The aim of this study was to determine epidemiological and overall survival (OS) characteristics of colorectal cancer (CRC) patients. Materials and Methods: Data of Ege University Cancer Control and Research Center between 1992- 2017 were screened retrospectively. Data recorded in CANREG program were grouped and analyzed in WHO and SEER systems. Chi-square test, General Linear Model (GLM) and Kaplan-Meier survival analysis were used for statistical analysis. Results: Number of CRC cases were 7285 (6.2%) among 117139 cancer cases. CRC ranked 7th among all the cancer types. Of the CRC patients, 4330 (59%) were male. The most common localization was rectum (38.4%). CRC increases with age. A significant increase was found at the age of 60 years and older (p=0.022) among both genders, but the difference between genders was not significant (p=0.299). Linear increase over the years was significant in total (GLM: F=12,349; p<0.0001). Adenocarcinoma (86%) was the most common histologic type, 54.2% of patients were diagnosed at locally advanced stage. The 5-year OS rate was 66.4% in locally advanced cancer and 15.8% in case of distant metastasis (p<0.0001). Median survival was 69 months, 5 and 10-year OS rates were 53% and 40% respectively. Ten-year OS was significantly higher in women. Five and 10- year OS rates were significantly lower in ≥70-year-old age group, and subsequently in the 20-29 years age group if ≥70-year-old age group was not taken into account (p<0.0001). Conclusion: There is an increase in CRC over the years, and generally the patients were diagnosed in locally advanced stages. The 5-year OS rate was 54.5% in the 60-69 age group which accounts for the most common age group, Ten-year OS rate was 43.3% in women which was higher than in men. Histology and stage were the most important prognostic parameters in prognosis.

Özet

Amaç: Kolorektal kanser (KRK) epidemiyolojisi ve genel sağ kalım (GSK) özelliklerinin araştırılmasıdır. Gereç ve Yöntem: Ege Üniversitesi Kanserle Savaş Uygulama ve Araştırma Merkezine (EÜKAM) 1992-2017 yıllarında kayıtlı Ege Üniversitesi Tıp Fakültesi kanser verileri retrospektif olarak taranmıştır. CANREG özel bilgisayar programına kayıtlı veriler, WHO ve SEER sistemlerinde gruplanarak analizler yapılmıştır. İstatistiksel analizlerde Ki-kare, General Linear Model (GLM), Kaplan-Meier sağ kalım analizleri kullanılmıştır. Yerel etik kurul onayı alınmıştır. Bulgular: Toplam 117.139 kanser olgusunun 7.285‟i (%6,2) KRK‟dir. KRK sıklığı, tüm olgular içinde yedinci sırada saptanmıştır. Olguların 4.330‟u (%59) erkektir. Rektum yerleşimi, %38,4 olguda saptanmış olup, en sık lokalizasyondur. KRK yaşla artmaktadır; 60 yaş ve üzerinde her iki cinsiyette de anlamlı artış saptanmıştır (p=0,022); cinsiyetler arası fark anlamlı değildir (p=0,299). KRK‟de yıllara göre doğrusal artış toplamda anlamlıdır (GLM: F=12,349; p<0,0001). Olguların %86‟sı adenokarsinomdur, %54,2‟si lokal ileri evrede tanı almıştır. Lokal ileri evrede beş yıllık GSK %66,4 iken, uzak metastaz varlığında %15,8‟e düşmektedir (p<0,0001). Medyan sağ kalım 69 ay, beş ve 10 yıllık GSK oranları sırasıyla %53 ve %40‟tır. On yıllık GSK oranı kadınlarda istatistiksel olarak anlamlı yüksektir. Yetmiş yaş ve üstü, beş ve 10 yıllık GSK oranları istatistiksel olarak anlamlı düşüktür, 20-29 yaş olgularda GSK, 70 yaş ve üstü dikkate alınmazsa anlamlı düşük bulunmuştur (p<0,0001). Sonuç: Hastanemizde yıllara göre KRK‟de artış vardır, tanı genellikle lokal ileri evrede konulmuştur. En sık görülme yaşı olan 60-69 yaş grubunda beş yıllık GSK %54,5‟dir. On yıllık GSK kadınlarda %43,3 olup erkeklerden daha yüksektir. Prognozda histoloji ve evre en belirleyici parametrelerdir.
