A Comparative Statistical Study of the Prevalence of Bladder and Rectal Cancer Among Patients in Najaf Province, Iraq

Abstract Background: Bladder cancer begins when cells in the bladder begin to grow uncontrollably. Rectal cancer is a type of cancer that forms in the tissues of the rectum. Cancer has become more prevalent in recent years, with bladder and colorectal cancer metastasizing to the other. Objectives: The study aimed to create statistics for bladder and rectal cancer for the years 2015–2020. Materials and Methods: This study retrospectively reviewed National Hospital for Oncology and Blood Diseases (NHOBD) records for all patients with advanced metastatic bladder and rectal cancer. Age and gender were recorded. The wide range of possibilities of involvement of bladder and rectal cancer requires patient- and disease-specific approaches. Cystectomy for adherent or invasive colorectal cancers achieves good local control. Results: Data were collected from NHOBD for bladder and rectal cancer for the years 2015–2020, where each year included different ages classified within age groups and categories (15–25, 26–36, 37–47, 48–58, 59–69, 70–80, and 81–91). Gender and age were taken into account, and the percentage, prevalence rate, and change in mortality rate in cases were calculated for cases of bladder and rectal cancer, and whether there was an increase or decrease in the number of cases. Conclusion: It was found that cancers increase with age and that the percentage of change is positive, indicating an increase. All results were assessed statistically using a program (Statistical Package for Social Sciences) version20, and thus it is considered a preliminary study for subsequent studies.
