Differences in clinical and pathological characteristics of colorectal cancer in Arab as compared to Jewish patients in Northern Israel.
The Incidence of colorectal cancer (CRC) differs in different ethnic groups. The aim of this study is to investigate clinical and pathological features of CRC in Arab as compared to Jewish patients in Northern Israel. Clinical and pathological characteristics of 480 patients with CRC treated between 1999 and 2006 were retrospectively reviewed. Eighty-five percent of the patients were Jews and 15% were Arabs. Mean age at diagnosis was 67.1 years in Jews and 58.3 years in Arabs (P < 0.001). Stage I CRC was 17.5% versus 7.2% (P < 0.05), Stage II was 35.5% versus 27.5% (P < 0.01), Stage III was 26% versus 33.3% (P:0 < 0.01) and Stage IV 21% versus 31% (P < 0.01) in Jewish and Arab patients respectively. In 40.6% of Jewish patients, cancer was well differentiated compared to 27.1% of Arab patients (P < 0.01) and poorly differentiated in 5.5% versus 10,4% (P < 0.05). Abdominal pain, constipation and weight loss were more common in Arabs than in Jews (P < 0.05). In conclusion CRC is more advanced, more aggressive and more symptomatic in Arab than in Jewish patients. Arab patients are younger at the time of diagnosis. Screening for CRC should be started at earlier age in the Arab population than the population at large.
