“…Khoubi et al introduced exposure to poisons and pesticides as a risk factor for bladder cancer, but in the present study, the history of exposure to pesticides was not significantly correlated with the survival rate of patients with bladder cancer ( p > 0.05) [ 26 ]. We found that most farmers had attended Agricultural Jihad’s training classes and put on personal protective gears during spraying.…”

Background Bladder cancer is one of the most common urinary tract cancers. This study aims to estimate the survival rate of patients with bladder cancer according to the Cox proportional hazards model based on some key relevant variables. Methods In this retrospective population-based cohort study that explores the survival of patients with bladder cancer and its related factors, we first collected demographic information and medical records of 321 patients with bladder cancer through in-person and telephone interviews. Then, in the analysis phase, Kaplan–Meier method and log-rank test were used to draw the survival curve, compare the groups, and explore the effect of risk factors on the patient survival rate using Cox proportional hazards model. Results The median survival rate of patients was 63.2 (54.7–72) months and one, three and five-year survival rates were 87%, 68% and 54%, respectively. The results of multiple analyses using Cox's proportional hazards model revealed that variables of sex (male gender) (HR = 11.8, 95% CI: 0.4–100.7), more than 65 year of age (HR = 4.1, 95% CI: 0.4–11), occupation, income level, (HR = 0.4, 95% CI: 0.2–0.8), well differentiated tumor grade (HR = 3.2, 95% CI: 1.7–6) and disease stage influenced the survival rate of patients (p < 0.05). Conclusion The survival rate of patients with bladder cancer in Kurdistan province is relatively low. Given the impact of the disease stage on the survival rate, adequate access to appropriate diagnostic and treatment services as well as planning for screening and early diagnosis, especially in men, can increase the survival rate of patients.

“…Numerous studies show that 20% of bladder cancer are caused by occupational exposure to bladder carcinogens that occur in industrial regions processing paint, dye, metal, pharmaceutical, and petroleum products. [2930] In some developing countries, by controlling occupational exposures to bladder carcinogens, cases of bladder cancer have decreased. [3536]…”

Mapping of stomach, colorectal, and bladder cancers in Iran, 2004–2009: Applying Bayesian polytomous logit model

Background:According to the last report of Iran cancer registry, stomach, colorectal, and bladder cancers are the most prevalent cancers. The present study focused on separating the latent risk surface into shared and disease-specific components.Methods:In this study, data consisting of stomach, colorectal, and bladder cancers in 30 provinces of Iran during 2004–2009 are considered. These data are analyzed by polytomous logit model. The incidence of stomach cancer acts as the reference category (the surrogate for smoking). Then, the log odds are decomposed into shared and specific structured spatial and unstructured spatial components. These latent components help to detect spatial patterns of shared and disease-specific risk factors.Results:Central, Southern, Eastern, and Southwestern provinces are supposed as high-risk regions for shared risk factor for colorectal and bladder cancers. This shared risk factor is slightly associated more with bladder than with colorectal cancer. Northern, northwestern, and central regions and also three borderline provinces in southwestern are high-risk regions for colorectal cancer. Central, eastern, southern, and western strip of the country except Ilam are found as the high-risk regions of bladder cancer.Conclusions:After considering known shared risk factor of the three cancers, it turns out that colorectal and bladder cancers have unknown shared risk factor. The significant difference in their lifestyle and eating habits could be an assumption of the risk factor.

“…In total, 20% of the causes of bladder cancer are due to occupational exposure. 34 Based on previous research, the chance of developing BC among bus and heavy drivers is 11.3 (1.3-92.05), in farmers, fisheries, and forestry, it is 6.0 (2.32-15.72), and among metalworkers and welders it is 6.0 (2.84-14.08), these all being higher than others, such as carpenters, at 0.68 (0.35-1.25) ( Table 5).…”

Bladder cancer is the sixth most common cancer in Iran. Information about the epidemiological situation of the disease and its risk factors is necessary for conducting a planning program to reduce the disease. This study is conducted with the aim of evaluating the epidemiological features of bladder cancer in Iran. Methods: This is a systematic review of the published articles in both Persian and English in international and national journals during the years 2000-2019 with key words of Iran and bladder cancer. Articles were selected from the national information database (SID, Magiran) and international databases (PubMed, Scopus, and Web of Science). Articles related to the epidemiological aspects of the disease, including incidence, prevalence, mortality, and risk factors, were evaluated. Results: The incidence rate of bladder cancer was about 1.6-115; cumulative survival rate was 0.95, mortality rate was 0.5-0.84 and its prevalence in the Iranian population was between 4.10% and 12.8%. The risk of developing malignancy in major risk factor groups, including smoking and opium, was 6.2 (2.04-18.7), increases in protein and animal fat consumption were about 5-and 19-times higher than in the general population, respectively. In terms of occupational exposure, bus and heavy truck drivers were 11.3 (1.3-92.05) more at risk than others. Conclusion: Regarding the increasing trend of this disease, changes in lifestyle to reduce risk factors can be effective in decreasing the incidence and mortality rate of this malignancy.
