Colorectal cancer is a common and lethal disease with 5000 new cases reported each year in Iran. This study was done to estimate the 1, 2-3 and 4-5 year point prevalence of colorectal cancer in Iran.
In this descriptive study we studied the follow-up of 2342 patients with colorectal cancer documented in the cancer registry in Iran during a time period of 4 years from March 2001 to March 2005. One-year, 2-3 year and 4-5 year point prevalence were estimated from incidence rates in different years and proportion of patients surviving 0.5, 1.5, 2.5, 3.5 and 4.5 years after diagnosis.
Proportion of cases surviving 0.5, 1.5, 2.5, 3.5 and 4.5 years from diagnosis were 79.2% , 65.08%, 57.36%, 51.76% and 48.87% respectively. Estimation of prevalence at 1, 2-3 and 4-5 years were 4156, 5715 and 4283 cases, respectively. Cumulative 5 year prevalence was 13954 cases.
Estimates of prevalence at 1, 2-3 and 4-5 years are necessary for the evaluation of initial treatment, clinical follow-up and point of cure, and also for identification of patients who need further social support or health care. Therefore 1, 2-3 and 4-5 year point prevalence estimation are necessary in health service planning for cancer management.
