The Economic Burden of Cancer in Iran during 1995-2019: A Systematic Review

The effects of FTO gene rs9939609 polymorphism on the association between colorectal cancer and dietary intake

Background

FTO gene is associated with obesity, dietary intake, and the risk of colorectal cancer (CRC). In this study, patients with colorectal cancer were assessed for the interactions between FTO gene polymorphisms and dietary intake.

Methods

This case-control study was carried out on 450 participants aged 35-70 years including 150 patients with colorectal cancer and 300 healthy controls. Blood samples were collected in order to extract DNA and genotyping of FTO gene for rs9939609 polymorphism. A validated 168-item food frequency questionnaire (FFQ) and the Nutritionist-IV software were used to assess dietary intake.

Results

In the participants with the TT genotype of FTO rs9939609 polymorphism, CRC risk was significantly associated with higher intake of dietary fat (OR:1.87 CI95%:1.76-1.99, p = 0.04), vitamin B3 (OR:1.20 CI95%:1.08-1.65, p = 0.04), and vitamin C (OR:1.06 CI95%:1.03-1.15, p = 0.04) and lower intake of β-carotene (OR:0.98 CI95%:0.97-0.99, p = 0.03), vitamin E (OR:0.77 CI95%:0.62-0.95, p = 0.02), vitamin B1 (OR:0.15 CI95%:0.04-0.50, p < 0.01), and biotin (OR:0.72 CI95%:0.0.57-0.92, p = 0.01). No significant association was found between CRC and dietary intake in carriers of AA/AT genotypes after adjustments for the confounders.

Conclusion

CRC risk may be decreased by β-carotene, vitamins E, B1, and biotin only in those without the risk allele of the FTO gene. The association of CRC and diet may be influenced by FTO genotype. Further studies are warranted.

An application of a series of theory-based educational intervention based on the health belief model on skin cancer prevention behaviors in female high school students

Background

Cancer is a leading cause of death globally and the second cause of death in developed countries. Having a rising incidence, skin cancer is the most prevalent cancer in Iran. Long-term UV radiations, particularly during childhood and adolescence, is a major cause of skin cancers. The Theory of Planned Behavior as the most precise indicator of behavior, contains motivational factors affecting behavior. This theory has been successful in predicting factors related to chronic diseases, especially cancer. As this model was successful in assessing sun-protective behaviors in previous studies, this study was designed to figure out how a theory-based educational intervention can affect the skin cancer prevention practices of Iranian female high school students.

Methods

This experimental investigation was carried out 2019-2020 using multistage cluster sampling method on 400 female high school students in Fasa, Fars, Iran. A questionnaire consisting of demographic data and a questionnaire including the components of the Theory of Planned Behavior was used to assess skin cancer preventative behaviors of both the trial and control groups of the study. An educational program based on the Theory of Planned Behavior was held for the experimental group for eight weeks regarding skin cancer preventive behaviors. The two groups completed questionnaires three months following the intervention for a second time.

Results

The study's findings revealed that prior to the intervention, there was no considerable distinction between the two study groups with regard to knowledge, attitude, subjective norms, perceived behavioral control, behavioral intentions, and skin cancer prevention behaviors; yet, three months later, the experimental group demonstrated increases in each of the mentioned variables with a significant difference. In contrast, the control group showed no discernible difference.

Conclusions

The findings of this investigation highlighted the success of the Theory of Planned Behavior for designing educational interventions aimed at encouraging skin cancer prevention in a population of female high school students.

The study of trends in mortality of respiratory system cancers in Babol, North of Iran (2013-2021)

Background

In Iran, cancers are known as the second leading cause of death, among which respiratory system cancers are particularly important because lung cancer is the second most common cause of death in this country. This study aimed to estimate the crude and age-standardized mortality and its trends during 9 years in the Northern city of Iran, Babol.

Methods

In this cross-sectional study, all the recorded deaths due to respiratory system cancers in Babol during the years 2013-2021 on the Classification of Causes of Deaths and Death Registration System of Babol University of Medical Sciences were taken into consideration, and the population estimate was based on the latest census. Finally, the crude and age-standardized rates of mortality and trends of cancer incidents were calculated.

Results

In general, 393 deaths with an overall mean age of 67.8±3.9 years have happened due to respiratory system cancers. The crude and standardized rates of respiratory system cancers increased from 6.5 and 5.5 per hundred thousand people in 2013 to 9.1 and 7.8 per hundred thousand people in 2021, respectively. With each decade in age, their trends increased significantly in men (p=0.024) and remained constant in women (p=0.262). In examining the trend of respiratory system cancers, we found an increasing trend for lung cancer and a constant trend for larynx and oropharynx cancers. There was also a decreasing trend for hypopharyngeal cancer.

Conclusions

The age-standardized rate and trend of respiratory system cancers are increasing. Therefore, it is important to prevent their prevalence by reducing the risk factors and increasing the general awareness of risks and timely diagnosis.

The Validation of the COmprehensive Score for Financial Toxicity (COST) Scale in Greek Language

The aim of this study was to investigate the psychometric properties of the Greek version of FACIT-COST, as well as to assess the levels of financial distress of patients suffering from lung cancer in relation to their quality of life and lung cancer symptom burden. This was a cross-sectional quantitative study. A self-assessment instrument was used to gather the data. The study involved 120 lung cancer patients who were treated using chemotherapy in a day clinic of a General Hospital in Athens. Data were collected with the COST-FACIT-v2 (used to assess the patients' financial toxicity), The 12-item Health Survey (SF-12), and functional Assessment of Cancer Therapy-Lung Symptom Index Questionnaire-7 items-version 4 (FACIT-FACT-LCS). Descriptive statistics as well as exploratory factor analysis performed all the statistical analyses, which were conducted using IBM SPSS Statistics 25 and had p-values with a significance level of 0.05. The majority of the participants were male (68.3%), married or cohabitated (81.3%), and had been diagnosed with microcell cancer (90%). The factor analysis resulted in one factor that interpreted 35% of the total variance. FACT-L (r = 0.365, p < 0.001), physical component SF-12 (r = 0.184, p = 0.045), and mental health component SF-12 (r = 0.268, p = 0.003) were positively correlated to FACIT-OST, as expected. The Greek validated COST-FACIT-v2 is a reliable tool in providing rapid assessment of cancer patients' level of financial distress.

A systemmatic literature review on indirect costs of women with breast cancer

INTRODUCTION

The rising incidence of breast cancer places a financial burden on national health services and economies. The objective of this review is to present a detailed analysis of the research and literature on indirect costs of breast cancer.

METHODS

English literature databases from 2000 to 2020 were searched to find studies related to the objective of the present review. Study selection and data extraction was undertaken independently by two authors. Also, quality assessment was done using a checklist designed by Stunhldreher et al. RESULTS: The current study chose 33 studies that were eligible from a total of 2825 records obtained. The cost of lost productivity due to premature death based on human capital approach ranged from $22,386 to $52 billion. The cost burden from productivity lost due to premature death based on friction cost approach ranged from $1488.61 to $4,518,628.5. The cost burden from productivity lost due to morbidity with the human capital approach was reported as $126,857,360.69 to $596,659,071.28. The cost of lost productivity arising from informal caregivers with the human capital approach was $297,548.46 to $308 billion.

CONCLUSION

Evaluation of the existing evidence revealed the indirect costs of breast cancer in women to be significantly high. This study did a thorough review on the indirect costs associated with breast cancer in women which could serve as a guide to help pick the appropriate method for calculating the indirect costs of breast cancer based on existing methods, approach and data. There is a need for calculations to be standardised since the heterogeneity of results in different domains from various studies makes it impossible for comparisons to be made among different countries.

Long-Term Oncologic Outcome of Breast Cancer in Southern Iran: A Retrospective Cohort Study

INTRODUCTION

Breast cancer remains the most frequent and lethal cancer among women worldwide. This study aimed to investigate the characteristics, prognostic factors and outcome of breast cancer patient treated and followed-up in Shiraz, southern Iran from 2000 to 2005.

METHODS

In this retrospective study, 1,024 patients with breast cancer who were treated in Namazi hospital of Shiraz University of Medical Sciences between 2000 and 2005 were included. Survival analysis was performed to determine potential factors influencing disease free-and overall survival in these patients.

RESULTS

Median age of the patients at diagnosis was 47 (range 19-83) years. Median follow-up for surviving patients was 68 months. The majority of patients presented at stage II (42%) and stage III (41%). Additionally, most (61%) patients had positive axillary node. The 5-, 10- and 15-year overall survival rates were 83.8%, 61.5% and 56.6% respectively. On multivariate analysis for overall survival, histologic type, Tumor stage, node stage, disease stage, M stage, hormone receptor status, adjuvant radiotherapy, and chemotherapy regimen remained independent prognostic factor for overall survival.

CONCLUSION

in this study, the poor long-term oncologic outcome of the patients with breast cancer may be due to the higher rate of locally advanced disease; as well as the lack of modern systemic therapies in the study period.

The prevalence of depression and anxiety in patients with cancer in Iran: a systematic review and meta-analysis

BACKGROUND

Cancer is one of the most prevalent diseases and is recognized as a global problem that is currently showing a growing trend. Cancer is one of the most stressful circumstances that a person may experience. Given how the mental state of patients with depression and anxiety may have a negative impact on their experience with cancer, this study was conducted with the aim to investigate the prevalence of anxiety and depression in cancer patients in Iran.

METHODS

This study was conducted using a systematic review method and based on the guideline Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA 2020). The studies used were searched for via databases, Scopus, Web of Science (WOS), Google Scholar, SID, Magiran, and using keywords related to anxiety, depression, and cancer. After extracting the required data, statistical analysis was performed based on the random model and using the second version of Comprehensive Meta-Analysis Software.

RESULTS

In a review of 24 studies with a sample size of 3225 people, the overall prevalence of depression in cancer patients in Iran was reported to be 50.1% (95% CI: 40.6-59.6). Additionally, in a review of 15 studies with a sample size of 2009, the overall prevalence of anxiety in cancer patients in Iran was reported to be 40.9% (95% CI: 30.9-51.6). The highest reported prevalence of depression in cancer patients in Iran according to the Beck questionnaire is 64.6 (95% CI: 48.2-78.1). Specifically, the highest prevalence of depression was reported in patients with breast cancer with a prevalence of 66 (95% CI: 50.9-78.4). The highest prevalence of anxiety in patients with cancer in Iran according to the Depression, Anxiety, and Stress Scale was 49.2 (95% CI: 18.9-80.1). Comparatively, the highest prevalence of anxiety in patients with breast cancer was reported to be 53.2 (95% CI: 25.8-78.7).

CONCLUSION

The prevalence of depression and anxiety among cancer patients in Iran, in particular patients with breast cancer, is significantly higher than in other parts of the world. The prevalence found in our study was even higher than the reported number by studies that have examined the disorder globally. Therefore, it is of great urgency for health system policymakers to work to improve the current situation.

Screening of ferroptosis-related genes with prognostic effect in colorectal cancer by bioinformatic analysis

Colorectal cancer (CRC) remains a common malignant tumor of digestive tract with high incidence rate and high mortality in the worldwide. The current clinical treatments of CRC often fail to achieve satisfactory results. Searching for more effective prediction or prognosis biomarkers, or developing more targeted therapeutic schedule may help to improve the outcomes of CRC patients. Here, we tried to study the effect of ferroptosis-related genes on CRC prognosis and make it clearer that ferroptosis has connection with immune environment. First, we obtained gene expression data of CRC and normal tissues, as well as corresponding clinical data from the Gene Expression Omnibus (GEO) database and the Cancer Genome Atlas (TCGA) database. The differentially expressed genes (DEGs) were intersected with ferroptosis-related gene set downloaded from FerrDb database, and 93 abnormally expressed ferroptosis-related genes were obtained. Then, these genes were analyzed for functional enrichment. Univariate Cox regression and multivariate Cox regression analyses were performed to establish prognostic model based on ferroptosis-related genes. In the process of exploring the correlation between prognostic genes and immune infiltration, we found that these genes were closely related to B cells, CD8⁺ T cells, CD4⁺ T cells, macrophages and other cells in CRC. In addition, we found a large proportion of plasma cells and macrophages in TCGA-COADREAD. Finally, a prognostic nomogram of ferroptosis-related genes was established, including age, sex, grade and other predicted values. To summary, we established a prognostic model of colorectal cancer (CRC) based on ferroptosis-related genes and further explored the relationship between these genes with immune microenvironment.

Preferred place of death and end-of-life care for adult cancer patients in Iran: A cross-sectional study

Background

More than 50,000 deaths in terms of cancer occur annually in Iranian hospitals. Determining the preferred place of end-of-life care and death for cancer patients in Iran is a quality marker for good end-of-life care and good death. The purpose of this study was to determine the preferred place of end-of-life care and death in cancer patients.

Method

In 2021, the current descriptive cross-sectional investigation was carried out. Using the convenience sample approach, patients were chosen from three Tehran referral hospitals (the capital of Iran). A researcher-made questionnaire with three parts for demographic data, clinical features, and two questions on the choice of the desired location for end-of-life care and the death of cancer patients served as the data collecting instrument. Data were analyzed using SPSS software version 18. The relationship between the two variables preferred place for end-of-life care and death and other variables was investigated using chi-square, Fisher exact test, and multiple logistic regression.

Result

The mean age of patients participating in the study was 50.21 ± 13.91. Three hundred ninety (69.6%) of the patients chose home, and 170 (30.4%) patients chose the hospital as the preferred place of end-of-life care. Choosing the home as a preferred place for end-of-life care had a significant relationship with type of care (OR = .613 [95% CI: 0.383–0.982], P = .042), level of education (OR = 2.61 [95% CI: 1.29–5.24], P = 0.007), type of cancer (OR = 1.70 [1.01–2.89], P = .049), and income level (Mediate: (OR: 3.27 (1.49, 7.14), P = .003) and Low: (OR: 3.38 (1.52–7.52), P = .003). Also, 415 (75.2%) patients chose home and 137 (24.8%) patients chose hospital as their preferred place of death. Choosing the home as a preferred place of death had a significant relationship with marriage (OR = 1.62 [95% CI: 1.02–2.57], P = .039) and time to diagnostic disease less than 6 months (OR = 1.62 [95% CI: 0.265–0.765], P = .002).

Conclusion

The findings of the current research indicate that the majority of cancer patients selected their homes as the preferred location for end-of-life care and final disposition. Researchers advise paying more attention to patients’ wishes near the end of life in light of the findings of the current study. This will be achieved by strengthening the home care system using creating appropriate infrastructure, insurance coverage, designing executive instructions, and integration of palliative care in home care services.

Design, implementation, and evaluation of self-care program in the prevention of breast cancer among women in Isfahan: a community-based participatory action research protocol

Introduction

Breast cancer is one of the most prevalent cancers among women in Isfahan, Iran; however, its prevention is not desirable in this city. This disease poses several health, social and economic challenges for women. To promote women's self-care in breast cancer prevention, this study aims to design, implement and evaluate a self-care program among women in Isfahan through using a community-based participatory action research method.

Methods

The present study is based on a community-based participatory action research approach. In this study, the participatory action research includes four general phases of organizing, action planning, action, and rethinking. These phases are summarized as follows: In the organizing phase, the needs of the participants and the action research settings are examined. This means that the current situation is identified and the views of the process owners are assessed. In the action planning phase, using the results of the first phase, some strategies are designed to promote self-care behaviors in the prevention of breast cancer among women in Isfahan. In the implementation phase, the selected strategies are implemented with the help of the process owners. Finally, in the rethinking phase, the results of the implementation of the strategies are monitored and evaluated. This cycle continues until the intended results are achieved.

Discussion

Changing the role of individuals from a passive status to an aware and active status in the care process requires motivation, responsibility, and active participation of individuals in the disease control process. Moreover, many cultural and social factors affect the active participation of Iranian women. Therefore, individuals can be involved in promoting their health using a community-based participatory action research approach.

The association among calorie, macronutrient, and micronutrient intake with colorectal cancer: A case-control study

The risk of colorectal cancer (CRC) can be influenced by dietary components. This study aims to investigate the association between dietary intake and CRC in Iranian adults. This hospital‐based case–control study was performed on 160 patients with CRC and 320 healthy people. General and pathological data were collected through face‐to‐face interviews. A validated food frequency questionnaire (FFQ) was used to assess the intake of calories, macronutrients, and micronutrients. The case group had a significantly higher intake of calories, carbohydrates, vitamin A, vitamin K, fluoride, and molybdenum and a lower intake of vitamin E, vitamin B1, beta carotene, biotin, folate, magnesium, selenium, manganese, and fiber (all p < .001). CRC was positively associated with the intake of carbohydrate (OR: 1.01, CI% 1.03–1.01, p = .001), and vitamin A (OR: 1.009, CI 95% 1.006–1.01, p = .001) and negatively associated with intake of fiber (OR: 0.67, CI 95% 0.59–0.76, p = .001), beta carotene (OR: 0.99, CI 95% 0.99–0.99, p = .001), vitamin E (OR: 0.27, CI 95% 0.15–0.47, p = .001), folate (OR: 0.98 CI 95% 0.97–0.98, p = .001), and biotin (OR: 0.83, CI 95% 0.77–0.90, p = .001). The associations remained significant after adjusting for age and sex. Further adjustments for physical activity, alcohol consumption, and smoking did not change the results. The results identified that the risk of colorectal cancer can be influenced by dietary intake. Further longitudinal studies are needed to confirm these findings and to identify the underlying mechanisms of the effects of dietary components on the risk of colorectal cancer.

Cost-analysis of Treatment of Patients with Acute Myeloid Leukemia

Background: Acute myeloid leukemia (AML) is the second common leukemia (5.18%) and the third deadliest leukemia in Iran. Moreover, it is the fifth prevalent cancer in the world, which involves 8% of all cancers. Objectives: The aim of this study was to calculate direct medical and non-medical costs of AML in 2019. Methods: The present retrospective-descriptive analysis was conducted on 192 patients with AML aged 19 to 70 years from 2016 to 2018. The data were collected from hospital records and interviews with experts. The bottom-up micro-costing approach and payer perspective was considered for cost analysis status. The relationship of affective variables was investigated, using nonparametric tests, including Mann–Whitney and Kruskal–Wallis tests. Costs were divided into costs of diagnosis, hospitalization, medication, nursing, visit and consultation, operating room, and medical supplies. The data were described by mean ± standard deviation and reported by percentage and also analyzed by SPSS 11 software. Results: According to the findings, the average age of all patients was 43.91 years and 55.7% of the patients were male. The highest and the lowest diagnostic costs were associated with laboratory tests at $1656459.48 and ultrasound charges $4229.46, respectively. The total direct medical costs per patient were $1056624.78 with an average of $4846.90 and the cost of medication included 36% of the total costs. The direct medical and non-medical costs were $10485488.48 and $487522.87, respectively Conclusions: Costs of AML treatment were estimated to be $1056624.78. Finally, it can be concluded that the cost of AML in Iran is much cheaper than that compared to other countries and also due to hidden subsidies from the public sector, the payment from the patient's pocket is very small.
