Abstract 270: Trends in colorectal cancer survival in Arab World, 1990-2009

Abstract Introduction: Cancer survival is a key measure of the effectiveness of health-care systems. Globally, colon and rectum cancer ranked third for cancer incidence and fourth for cancer death in 2013. For developed countries it ranked second for incidence and mortality, and in developing countries it ranked fourth for both incidence and mortality. An increasing trend in incidence is reported from various registries of Arab world, Kuwait and Saudi Arabia present the highest incidences worldwide. Objective: To describe the trends of the survival of colorectal cancer patients diagnosed in Arab countries. Material and Methods: This report is a summary of the two survival figures of CONCORD study 1 (1990-1994) and CONCORD study 2 (1995-2009). Individual colon and rectum tumour records were submitted by 06 population-based cancer registries in Arab countries (Jordan, Saoudi Arabia, Qatar, Algeria, Lybia and Tunisia) for 9050 patients (15-99 years) diagnosed during 1990-2009 and followed up to 31 December 2009 . Estimated five-year net survival, adjusted for background mortality by single year of age, sex, calendar year in each country. Results : For patients diagnosed during the period 2005-2009, the age-standardized five-years net survivals were respectively higher 68,2% for colon cancer and 77,8% for rectum cancer in Qatar and the lowest rate for rectal cancer 21% in Jordan, between 1995-1999 and 2005-2009, Survival increased in Algeria, but this trend is less reliable Conclusions: Comparison of population-based cancer survival CONCORD study showed very wide variations in survival from colorectal cancer in Arab world. Cancer survival research is being used to formulate cancer control and the need to implement effective strategies of primary prevention. Note: This abstract was not presented at the meeting.
