Abstract

There is an increased risk of colorectal cancer (CRC) in ulcerative colitis (UC). The prevalence of UC associated CRC is different in various geographical regions. The risk depends primarily on the duration and extent of disease. The aim of the study was to identify risk factors for and epidemiology of CRC in UC patients in Veszprem province. From our thirty-year IBD database we retrospectively studied the relevant epidemiological and clinical data of all UC patients in Veszprem province. The data of 723 UC patients (m/f: 380/343) were evaluated. The rate of familial disease was 5.2%, the rate of non-CRC related colectomies was 3.7% in our UC patients. CRC was diagnosed in 13 patients (m/f: 6/7, 13/8564 person year duration) during follow-up. The onset of UC in the 13 patients with UC-CRC was 34.5 (13-61) years, 4.1 years younger compared to UC patients without CRC. Mean age of UC-CRC patients at diagnosis of CRC was 50.9 (27-70) years (duration of UC: 16.5 +/- 8.2 years), almost 15 years younger than the average in sporadic CRC population in Hungary. Eight patients are still alive (survival: 67.9 (10-163) months), four patients died because of CRC (survival: 8.0 months), one died due to unrelated cause after 10 years of the di...Continue Reading

Anemia

Anemia develops when your blood lacks enough healthy red blood cells. Anemia of inflammation (AI, also called anemia of chronic disease) is a common, typically normocytic, normochromic anemia that is caused by an underlying inflammatory disease. Here is the latest research on anemia.

Cancer Incidence & Mortality

Cancer has emerged as a global concern due to its increase in incidence and mortality. Efforts are underway to evaluate and develop action plans to reduce the global burden of cancer. Currently, lung cancer, breast cancer and prostate cancer are the leading causes of cancer mortality. Here is the latest research on cancer incidence and mortality.
