Trends in Incidence of Common Cancers in Iran

Abstract

Cancer is a major public health problem in Iran. The aim of this study was to evaluate trends in incidence of ten common cancers in Iran, based on the national cancer registry reports from 2004 to 2009. This epidemiological study was carried out based on existing age-standardized estimate cancer data from the national report on cancer registry/Ministry of Health in Iran. The obtained data were analyzed by test for linear trend and P ≥ 0.05 was taken as the significant level. Totals of 41,169 and 32,898 cases of cancer were registered in men and females, respectively, during these years. Overall age-standard incidence rates (ASRs) per 100,000 population according to primary site weres 125.6 and 113.4 in males and females, respectively. Between 2004 and 2009, the ten most common cancers (excluding skin cancer) were stomach (16.2), bladder (12.6), prostate (11), colon-rectum (10.14), hematopoeitic system (7.1), lung (6.1), esophagus (6.4), brain (3.2), lymph node (3.8) and larynx (3.4) in males; and in females were breast (27.4), colon-rectum (9.3), stomach (7.6), esophagus (6.4), hematopoeitic system (4.9), thyroid (3.9), ovary (3.6), corpus uteri (2.9), bladder (3.2) and lung (2.6). Moreover, results showed that skin cancer was estimated as the most common cancer in both sexes. The lowest and the highest incidence in females and males were reported respectively in 2004 and 2009. Over this period, the incidence of cancer in both sexes has been significantly increasing (p<0.01). Like other less developed and epidemiologically transitioning countries, the trend of age-standardized incidence rate of cancer in Iran is rising. Due to the increasing trends, the future burden of cancer in the Iran is going to be acute with the expected increases in aging populations. Determining and controlling potential risk factors of cancer should hopefully lead to decrease in its burden.

Preliminary study of prevalence for bladder cancer in Isfahan Province, Iran

“…The correlation between ageing and cancer is well represented in BC, as with advancing age, the risk of developing BC increases, and patients’ clinical presentation and outcomes worsen [17] . In agreement with previous reports, 86% of all BC cases were aged >50 years [1] , [2] , [3] , [4] , [5] , [6] , [7] , [8] , [9] , [10] , [11] , [12] , [13] , [14] , [15] , [16] , [17] , [18] , [19] .…”

“…Cancer is a leading cause of morbidity and mortality in the USA and results in a high economic burden [12] . Likewise according to published articles, cancer could be considered as a major public health problem in Iran too [13] , [14] , [15] . Furthermore, BC is reported to be the ninth most common cancer and the fourteenth leading cause of death from cancer worldwide [16] .…”

A Survey on Mental Health Status and Related Factors among Cancer Patients in Iran

“…Cancer is one of the most common non-communicable diseases and the second cause of death in Iran. The rate and prevalence of cancer has considerably increased over the recent years due to a myriad of factors such as aging population, industrialization, changes in the lifestyle, and environmental changes [1]. Skin cancer is one of the most common types of cancer in Iran with 7000 new diagnoses every year.…”

Survival rate of colon and rectum cancer in Iran: A systematic review and meta-analysis

“…According to Iran National Cancer Registry in 2014, CC with the total incidence rate of 9861 cases in 30 Provinces of Iran (Qom Province excluded) and the age-standardized rate of 16.57 and 11.86 per 100,000 was the fifth most prevalent cancer among men and the second one among women. Different studies indicated an increase in the incidence of this disease in recent years in Iran [3][4][5]. Cancer survival rate (SR) is a widely used indicator for physicians, patients and health policymakers, and reflects the prognosis of cancer patients [6].…”
