Demographic characteristics of patients with colorectal cancer

Öz

Aim: Colorectal cancers are one of the most important causes of cancer-related mortality and morbidity. It is the 3rd most common cancer diagnosed in men and the 2nd most common cancer diagnosed in women worldwide. While colon cancer is almost equally seen in men and women, rectal cancer is more common in men with a ratio of F:M = 1:1.3. Colorectal cancers are rare below the age of 50 years with a median age at diagnosis of 70 years. The aim was to investigate the general characteristics of patients diagnosed with colorectal cancer under follow-up, whether these characteristics are consistent with the literatüre or not. Material and Methods: The study was designed as a cross-sectional, retrospective cohort study. Patients diagnosed with colorectal cancer, who were followed up at the Oncology Clinic of Ankara Dışkapı Training and Research Hospital and whose diagnosis was confirmed by colonoscopy and histopathological examination, were evaluated between July 2011 and September 2015. Results: The study included 172 patients with stage I-IV colorectal cancer and their general characteristics were evaluated. The disease was found to be more common in the male sex than in the female sex in accordance with the literature. The median age of the patients was 62 years. The youngest patient was 27 years old and the oldest patient was 89 years old. It was found that 37% of male patients with CRC had rectal cancers and 61% had more proximal colon cancers, whereas 36% of female patients had rectal cancers and 38% had more proximal colon cancers. With this study, we have shown that colon cancers are a major cause of morbidity and mortality in our country as well as in the World

Kolorektal kanserli hastaların demografik özellikleri

Amaç: Kolorektal kanserler, kanserle ilgili mortalite ve morbiditenin en önemli sebeplerindendir. Tüm dünyada erkeklerde tanı alan en sık 3., kadınlarda ise en sık 2. kanserdir. Kolon kanseri erkek ve kadında hemen hemen eşit görülürken, rektal kanser erkeklerde K:E = 1:1.3 oranında daha sık görülür. Medyan tanı yaşı 70 olan kolorektal kanserler 50 yaş altında nadir görülür. Kolorektal tanısı ile takipli hastaların genel nitelikleri ve bu niteliklerin literatür ile uyumlu olup olmadığı araştırıldı. Gereç ve Yöntemler: Çalışma, kesitsel, retrospektif kohort çalışması olarak tasarlandı. Temmuz 2011- Eylül 2015 tarihleri arasında Ankara Dışkapı Eğitim ve Araştırma Hastanesi Onkoloji Kliniği’nde takip edilen, kolonoskopi yapılarak tanısı konulan ve histopatolojik olarak tanısı doğrulanan kolorektal kanserli vakalar değerlendirildi. Sonuç: Çalışmaya evre I-IV kolorektal kanserli 172 hasta alındı ve genel nitelikleri değerlendirildi. Hastalık literatür ile uyumlu şekilde erkek cinsiyette kadınlara göre daha sık tespit edildi Hastaların medyan yaşı 62 olarak saptandı. En genç hasta 27, en yaşlı hasta ise 89 yaşındaydı. KRK tanısıyla takip edilen erkek hastaların %37’sinde daha çok rektum kanserleri, %61’inde daha proksimal yerleşimli kolon kanserleri görülürken, kadınlarda %36 oranında rektum kanserleri ve buna yakın olarak %38 oranında daha proksimal yerleşimli kolon kanserleri görüldüğü saptanmıştır. Bu çalışmamız ile dünyada olduğu gibi ülkemizde de önemli morbidite ve mortalite nedenlerinden biri olan kolorektal kanserlerin demografik yapısını ve risk faktörlerini belirleyerek literatüre katkı sağlamayı amaçladık.
