Estimating the Cost of Illness of Prostate Cancer in Iran

The economic burden of prostate cancer in Iran: a cross-sectional cost-of-illness study

OBJECTIVE

This study aims to assess the economic burden of prostate cancer in Iran by analyzing direct medical costs, direct non-medical costs, and indirect costs. We conducted a cross-sectional cost-of-illness study in Khorramabad, located in western Iran, during 2023, using a prevalence-based, bottom-up approach. Data were collected from 285 prostate cancer patients using questionnaires, interviews, and patient records.

RESULTS

Our study estimated the economic burden of prostate cancer at $744,990. Direct medical costs accounted for 63.50% of this, totaling $153,330, with therapy being the largest component. Direct non-medical costs were $62,130, and indirect costs from productivity losses were $209,760. The calculated overall cost per patient was $2,614.88. Extrapolating from the 2021 Global Burden of Disease data, which reported approximately 83,000 prostate cancer patients in Iran, the national economic burden is estimated at $217,034,040. This substantial burden highlights the need for improved insurance coverage and early detection. The findings suggest that policymakers and healthcare providers in Iran should develop standardized cost analysis methods and enhance financial protection to alleviate economic strain and improve healthcare outcomes and sustainability.

Cost-Effectiveness Analysis of Triptorelin, Goserelin, and Leuprolide in the Treatment of Patients With Metastatic Prostate Cancer: A Societal Perspective

OBJECTIVES

Metastatic prostate cancer is the most common malignant cancer and the second leading cause of death due to various types of cancer among men after lung cancer. This study aimed to analyze the cost-effectiveness of triptorelin, goserelin, and leuprolide in the treatment of the patients with metastatic prostate cancer from the societal perspective in Iran in 2020.

METHODS

This is a cost-effectiveness study in which a 20-year Markov transition modeling was applied. In this study, local cost and quality-of-life data of each health state were gathered from cohort of patients. The TreeAge pro 2020 and Microsoft Excel 2016 software were used to simulate cost-effectiveness of each treatment in the long term. The one-way and probabilistic sensitivity analyses were also performed to measure robustness of the model outputs.

RESULTS

The findings indicated that the mean costs and utility gained over a 20-year horizon for goserelin, triptorelin, and leuprolide treatments were $ 13 539.13 and 6.365 quality-adjusted life-years (QALY), $ 18 124.75 and 6.658 QALY, and $ 26 006.92 and 6.856 QALY, respectively. Goserelin was considered as a superior treatment option, given the estimated incremental cost-effectiveness ratio. The one-way and probabilistic sensitivity analyses confirmed the robustness of the study outcomes.

CONCLUSIONS

According to the results of the present study, goserelin was the most effective and cost-effective strategy versus 2 other options. It could be recommended to policy makers of the Iran healthcare system to prioritize it in clinical guidelines and reimbursement policies.

A cost-benefit analysis of mass prostate cancer screening

BACKGROUND

Prostate cancer (PCa) causes a substantial health and financial burden worldwide, underscoring the need for efficient mass screening approaches. This study attempts to evaluate the Net Cost-Benefit Index (NCBI) of PCa screening in Iran to offer insights for informed decision-making and resource allocation.

METHOD

The Net Cost-Benefit Index (NCBI) was calculated for four age groups (40 years and above) using a decision-analysis model. Two screening strategies, prostate-specific antigen (PSA) solely and PSA with Digital Rectal Examination (DRE), were evaluated from the health system perspective. A retrospective assessment of 1402 prostate cancer (PCa) patients' profiles were conducted, and direct medical and non-medical costs were calculated based on the 2021 official tariff rates, patient records, and interviews. The monetary value of mass screening was determined through Willingness to Pay (WTP) assessments, which served as a measure for the benefit aspect.

RESULT

The combined PSA and DRE strategy of screening is cost-effective, yields up to $3 saving in costs per case and emerges as the dominant strategy over PSA alone. Screening for men aged 70 and above does not meet economic justification, indicated by a negative Net Cost-Benefit Index (NCBI). The 40-49 age group exhibits the highest net benefit, $13.81 based on basic information and $13.54 based on comprehensive information. Sensitivity analysis strongly supports the cost-effectiveness of the combined screening approach.

CONCLUSION

This study advocates prostate cancer screening with PSA and DRE, is economically justified for men aged 40-69. The results of the study recommend that policymakers prioritize resource allocation for PCa screening programs based on age and budget constraints. Men's willingness to pay, especially for the 40-49 age group which had the highest net benefit, leverages their financial participation in screening services. Additionally, screening services for other age groups, such as 50-54 or 55-59, can be provided either for free or at a reduced cost.

Optimal age to stop prostate cancer screening and early detection

BACKGROUND

Prostate Cancer screening should be discontinued at older ages because competing mortality risks eventually dominate the risk of Prostate Cancer and harms exceed benefits. We explored the Prostate Cancer screening stopping age from the patient, healthcare system, and social perspectives in Iran.

METHODS

We applied Bellman Equations to formulate the net benefits biopsy and "do nothing". Using difference between the net benefits of two alternatives, we calculated the stopping age. The cancer states were without cancer, undetected cancer, detected cancer, metastatic cancer, and death. To move between states, we applied Markov property. Transition probabilities, rewards, and costs were inferred from the medical literature. The base-case scenario estimated the stopping age from the patient, healthcare system, and social perspectives. A one-way sensitivity used to find the most influential parameters on the stopping age.

RESULTS

Our results suggested that Prostate Cancer screening stopping ages from the patient, healthcare system, and social were 70, 68, and 68 respectively. The univariate sensitivity analysis showed that the stopping ages were sensitive to the disutility of treatment, discount factor, the disutility of metastasis, the annual probability of death from other causes, and the annual probability of developing metastasis from the hidden cancer state.

CONCLUSIONS

Men should not be screened for Prostate Cancer beyond 70 years old, as this results in the net benefit of "do nothing" above the biopsy. Nevertheless, this finding needs to be further studied with more detailed cancer progression models (considering re-biopsy, comorbidities, and more complicated states transition) and using local utility and willingness to pay value information.

Financial burden of prostate cancer in the Iranian population: a cost of illness and financial risk protection analysis

BACKGROUND

Prostate cancer is the second most common cancer in males worldwide and the third most common among Iran's male population. However, there is a lack of evidence regarding its direct and indirect costs in low and middle-income countries. This study intends to bridge the gap using a cost of illness approach, assessing the costs of prostate cancer from the perspectives of patients, society, and the insurance system.

METHODS

Two hundred ninety seven patients were included in the study. Data for a 2-month period were obtained from patients registered at two hospitals (Tabriz, Tehran) in Iran in 2017. We applied a prevalence-based, bottom-up approach to assess the costs of the illness. We used the World Health Organization methods to measure the prevalence and investigate the determinants of catastrophic and impoverishing health expenditures.

RESULTS

We determined the total costs of the disease for the patients to be IRR 68 million (PPP $ 5,244.44). Total costs of the disease from the perspective of the society amounted to IRR 700,000 million (PPP $ 54 million). Insurance companies expended IRR 20 million (PPP $ 1,558.80) per patient. Our findings show that 31% of the patients incurred catastrophic health expenditure due to the disease. Five point forty-four percent (5.44%) of the patients were impoverished due to the costs of this cancer.

CONCLUSION

We found an alarmingly high prevalence of catastrophic health expenditures among prostate cancer patients. In addition, prostate cancer puts a substantial burden on both the patients and society.

Global and regional quality of care index for prostate cancer: an analysis from the Global Burden of Disease study 1990-2019

BACKGROUND

Prostate cancer (PCa) is one of the most prevalent cancers worldwide, with a significant burden on societies and healthcare providers. We aimed to develop a metric for PCa quality of care that could demonstrate the disease's status in different countries and regions (e.g., socio-demographic index (SDI) quintiles) and assist in improving healthcare policies.

METHODS

Basic burden of disease indicators for various regions and age-groups were retrieved from Global Burden of Disease Study 1990-2019, which then were used to calculate four secondary indices: mortality to incidence ratio, DALYs to prevalence ratio, prevalence to incidence ratio, and YLLs to YLDs ratio. These four indices were combined through a principal component analysis (PCA), producing the quality of care index (QCI).

RESULTS

PCa's age-standardized incidence rate increased from 34.1 in 1990 to 38.6 in 2019, while the age-standardized death rate decreased in the same period (18.1 to 15.3). From 1990 to 2019, global QCI increased from 74 to 84. Developed regions (high SDI) had the highest PCa QCIs in 2019 (95.99), while the lowest QCIs belonged to low SDI countries (28.67), mainly from Africa. QCI peaked in age groups 50 to 54, 55 to 59, or 65 to 69, depending on the socio-demographic index.

CONCLUSIONS

Global PCa QCI stands at a relatively high value (84 in 2019). Low SDI countries are affected the most by PCa, mainly due to the lack of effective preventive and treatment methods in those regions. In many developed countries, QCI decreased or stopped rising after recommendations against routine PCa screening in the 2010-2012 period, highlighting the role of screening in reducing PCa burden.

Determinants and economic burden of HIV/AIDS in Iran: a prospective study

BACKGROUND

Since the start of the AIDS outbreak, the human immunodeficiency virus (HIV) has infected about 84.2 million people, and approximately 40.1 million people have died due to AIDS-related diseases. So, this study aims to provide a comprehensive population-based description of patient costs and the economic burden of HIV/AIDS in Iran.

METHODS

The study population of this cross-sectional cost-of-illness study consisted of HIV-infected patients who were receiving services in Mashhad and were under the supervision of BIDCC. There are four BIDCC centers in Mashhad, we considered all patients referred to these centers. Costs data were evaluated from a social perspective with a bottom-up approach and as a prevalence based. The data from 157 individuals were included in the study. For collecting data on direct and indirect costs belonging to patients and their families, a questionnaire was developed. Also, the Demographic characteristic of participants and the stage of the disease and Transmission category were analyzed.

RESULTS

In this study, 57.32 of the subjects were Male. The majority of participants in this study were in the age group 30-59 years (n = 124,78.98%). Based on where the patients live, the majority of patients have lived in the urban region (n = 144, 91.72%). The most common way to transmit this disease is through unprotected sex (30.57%) and then Infected spouse (28.03%), and then injecting drugs (21.02%). The highest cost of this disease is attributed to medicine (10339.32 $ for 6 months), after medicine, the cost of tests was 9101.22 $.

CONCLUSION

It seems that to reduce costs for patients with disease HIV/AIDS, the focus should be on diagnostic tests and care. Early diagnosis and rapid initiation of antiviral treatments can be effective in preventing serious and debilitating diseases.

Targeting the MALAT1 gene with the CRISPR/Cas9 technique in prostate cancer

BACKGROUND

The MALAT1 lncRNA acts as an oncogene in Prostate cancer (PC); thus, it can be severe as a cancer biomarker.

METHODS

Using bioinformatics datasets including (HTSeq-Counts, GDC, and TCGA) 5501 gene expression profiling specimens were gathered. Then, expression profiles and sample survival of lncRNA were investigated using COX regression analyses, ROC curve analysis. The Database for Annotation, Visualization, and Integrated Discovery was used to conduct GO and KEGG studies on the lncRNA-related PCGs. After MALAT1 Knockout via CRISPR/Cas9 technique, the MALAT1 expression was assessed in DU-145 cells. The deletion of the target fragment was examined by polymerase chain reaction (PCR). Also, the expression of apoptosis genes was investigated by qRT-PCR. The viability and cell proliferation were measured using the MTT assay. Cell migration capability was determined using the cell scratch assay. The results of qRT-PCR were assessed by the ΔΔCt method, and finally, statistical analysis was performed in SPSS software.

RESULTS

A maximum of 451 lncRNAs were discovered to reflect different expressions between PC and non-carcinoma tissue samples, with 307 being upregulated and 144 being down-regulated. Thirty-six lncRNAs related to OS were carefully selected, which were then subjected to stepwise multivariate Cox regression analysis, with 2 lncRNAs (MALAT1, HOXB-AS3). MALAT1 is highly expressed in PC cells. MALAT1 Knockout in DU-145 cells increases apoptosis and prevents proliferation and migration, and DU-145 transfected cells were unable to migrate based on the scratch recovery test. Overall, data suggest that MALAT1 overexpression in PC helps metastasis and tumorigenesis. Also, MALAT1 knockout can be considered a therapeutic and diagnostic target in PC.

CONCLUSION

Targeting MALAT1 by CRISPR/Cas9 technique inhibit the cell proliferation and migration, and in addition induce apoptosis. Thus, MALAT1 can act as a tumor biomarker and therapeutic target.

The economic burden of prostate cancer in Eswatini

Background

Prostate cancer is the fifth cause of cancer mortality among men worldwide. However, there is limited data on costs associated with prostate cancer in low- and middle-income countries particularly in the sub-Saharan region. From a societal perspective, this study aims to estimate the cost of prostate cancer in Eswatini.

Methods

This prevalence–based cost-of-illness study used diagnosis specific data from national registries to estimate costs associated to prostate cancer during 2018. The prevalence-based approach was used employing both top down and bottom up costing approaches. Costs data included health care utilization, transport, sick leave days and premature death.

Results

The total annual cost of prostate cancer was $6.2 million (ranging between $ 4.7 million and 7.8 million estimated with lower and upper bounds). Average cost-per patient for radiotherapy, chemotherapy and other non-medical direct costs (transport and lodging) were the highest cost drivers recording $16,648, $7,498 and $5,959 respectively whilst indirect costs including productive loss due to sick leave and pre-mature mortality was estimated at $58,320 and $113,760 respectively. Cost of managing prostate cancer increased with advanced disease and costs were highest for prostate cancer stages III and IV recording $1.1million, $1.9million respectively.

Conclusions

Prostate cancer is a public health concern in Eswatini, and it imposes significant economic burden to the society. This finding point areas for policy makers to perform cost containment regarding therapeutic procedures for prostate cancer and the need for strategies to increase efficiencies in the health care systems for increased value for health care services.

Cost-effectiveness analysis of rituximab versus natalizumab in patients with relapsing remitting multiple sclerosis

Introduction

Multiple sclerosis (MS) is an inflammatory disease in which the myelin sheaths of the nerve cells in the brain and spinal cord, which are responsible for communication, are destroyed and cause physical signs and symptoms. According to studies, anti-CD20 monoclonal antibodies have significant results in the treatment of this disease. Thus, the aim of the present study was to determine the cost-effectiveness of rituximab against natalizumab in the patients with RRMS in southern Iran in 2020.

Methods

This is an economic evaluation including cost-effectiveness analysis in which the Markov model with a lifetime horizon was used. The study sample consisted of 120 patients randomly selected from among those referred to the MS Association and the Special Diseases Unit of Shiraz University of Medical Sciences. In this study, the costs were collected from a societal perspective, and the outcomes were obtained in the form of Quality Adjusted Life Years (QALY) and the mean relapse rate. The TreeAge pro 2020 and Excel 2016 software were used for data analysis.

Results

The comparative study of rituximab and natalizumab showed that the patients receiving rituximab had lower costs ($ 58,307.93 vs. $ 354,174.85) and more QALYs (7.77 vs. 7.65). In addition, the incidence of relapse by rituximab was lower compared to natalizumab (1.15 vs. 2.57). The probabilistic one-way sensitivity analysis showed the robustness of the results. The scatter plots also showed that rituximab was more cost-effective for the patients in 100% of the simulations for the threshold of < $ 37,641.

Discussion and conclusion

According to the results of this study, rituximab had higher cost-effectiveness than natalizumab. Therefore, it could be a priority for RRMS patients compared to natalizumab because it reduced treatment costs and increased effectiveness.

Overall survival and prognostic factors prostate cancer in Kurdistan Province-Iran: a population-based study (2011-2018)

Background

The population-based survival rate is affected by the quality and effectiveness of health care systems. Overall, the survival of prostate cancer (PC) patients has improved over the past two decades worldwide. This study aimed to determine the overall survival rate and correlate it with the prognostic factors in patients with PC diagnosed in Kurdistan province.

Methods

In a retrospective cohort study, 410 PC patients registered in Kurdistan province population-based cancer registry from March 2011 to 2018 were recruited. Kaplan–Meier method and log-rank test were used to analyze the overall survival rates of PC patients. A Multivariate Cox regression model was used to determine adjusted hazard ratios for different variables.

Results

Of 410 patients with PC, 263 (64.1%) died within seven years due to the disease. The 1, 3, and 5 years survival rates were 93, 64.1, and 40.7%, respectively. According to the results of multiple Cox regression, the following factors were significantly related to PC survival: age at diagnosis (≥81-years old) (HR=2.23, 95% CI: 1.23-4.42) and 71-80 years old was (HR=1.26, 95% CI: 1.12-2.31), occupation (employee) (HR=0.42, 95% CI: 0.20–0.87), educational level: academic (HR=0.78, 95% CI: 0.64–0.91), AJCC stage of disease (HR=2.18, 95% CI: 1.9–3.68), Gleason score ≥ 9 (HR=7.12, 95% CI: 5.35–10.28), and Gleason score= 8 (HR=4.16, 95% CI: 2.50–6.93). There was less mortality rate among the patients who had received active care, radical prostatectomy, radiotherapy, combined treatment, and orchiectomy had a lower mortality rate than those who received no treatment (P<0.05).

Conclusions

This study demonstrated that factors such as age at diagnosis, level of education, occupation, AJCC stage of disease, Gleason score, and type of treatments were influential factors in the survival of PC patients in Kurdistan province and needed more attention.

Burden of Treatment among Elderly Patients with Cancer: A Scoping Review

Background: The objective of this scoping review is to understand how treatment burden is experienced in elderly patients with cancer and what the most prevalent dimensions of treatment burden are among this population. According to one conceptual model, there are six dimensions of treatment burden, including financial, medication, administrative, time/travel, lifestyle, and healthcare. Methods: A scoping review methodology framework was used to collected data from EMBASE CINAHL (Cumulative Index to Nursing and Allied Health Literature), Medline/PubMed, Scopus, Web of Science, Embase, and Cochrane from 2000 to March 2020. Studies which focused on treatment burden among elderly patients with cancer (+65 years) were selected. Data were extracted using a standardized proforma. Results: The results identified 3319 total papers. Of these, 24 met the inclusion criteria and were included in the scoping review. A significant proportion of these studies was conducted in the United States (n = 10) using self-reported, cross-sectional data. Financial burden was the most prevalent dimension of treatment burden, with 11 studies focusing on the direct and indirect costs associated with cancer treatment. Other but less obvious aspects of treatment burden elderly patients experienced included the length of time taken to access and administer treatment and medication-related burdens. Conclusions: Emerging findings suggest that the financial aspects of cancer treatment are a significant burden for most elderly cancer patients. Personalized healthcare interventions targeting ways to reduce and screen for treatment burden, particularly those related to cost, are urgently needed.

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

Background

Cancer is the third cause of death following cardiovascular disease and accidents, in Iran. The purpose of this study was to systematically review the economic burden of cancer studies in Iran.

Methods

This systematic review examined the types of direct medical and non-medical costs and indirect costs in cancer patients and includes studies in English and Persian that were reviewed in Scopus, Web of science, SID, Iranmedex, Magiran and databases of Medline, etc., from 1995-2019.

Results

Twenty-one articles were included. Most studies have examined the direct costs of all types of cancers. The articles reviewed different types of cancer, such as prostate cancer (n=2), colorectal cancer (n=2), breast cancer (n=4), gastric cancer (n=2), oral and pharyngeal cancer (n=1), lung cancer (n=3), and blood cancer (n=4). The great number of studies were related to the gastrointestinal, breast and blood cancers. The gastrointestinal (gastric and colorectal) and breast cancer had the major economic burden than others.

Conclusion

It is necessary that special attention to patients, supportive measures to reduce the share of costs, and more budget allocation for prevention, screening and early detection being at priorities in the health system planning.

In order to improve the quality of life of older patientsand their family caregivers.

A theoretical model of financial burden after cancer diagnosis

Current models of financial burden after cancer do not adequately define types of financial burden, moderators or causes. We propose a new theoretical model to address these gaps. This model delineates the components of financial burden as material and psychological as well as healthcare-specific (affording treatment) versus general (affording necessities). Psychological financial burden is further divided into worry about future costs and rumination about past and current financial burden. The model hypothesizes costs and employment changes as causes, and moderators include precancer socioeconomic status and post-diagnosis factors. The model outlines outcomes affected by financial burden, including depression and mortality. Theoretically derived measures of financial burden, interventions and policy changes to address the causes of financial burden in cancer are needed.
