<p>Cancer Incidence Trends From 1999 to 2015 And Contributions Of Various Cancer Types To The Overall Burden: Projections To 2030 And Extrapolation Of Economic Burden In Saudi Arabia</p>

Abstract

Background: Cancer incidence in Saudi Arabia has increased for the last two decades, ratcheting up to global levels. The study aimed to analyze cancer trends and the contributions of various cancer types, forecast incidence, and estimate the economic burden in 2030. Methods: A national-level cohort study utilizing the Data of Cancer Registry of patients who were diagnosed in 1999-2015. New cases in 2016-2030 were forecast and predicted based on 1999-2015 data. We used growth assumption and regression analysis to predict the trends of cancer cases. We assessed the contributions of cancer types to incidence trends. We carried forecasting of new cases and extrapolation of the potential economic burden. We conducted a sensitivity analysis of the cost of cancer with respect to changes in economic and epidemiologic factors. Results: The findings suggest that the number of known cancer cases increased by 136% from 1999 to 2015 and is projected to rise by 63% in 2030. The forecast indicates female cases will account for higher number of cases and greater proportion increase. The future cost of all cancer types would be estimated at $7.91 billion in 2015 value, of which $3.76 billion will be attributable to care management and $4.15 billion in lost productivity. With the assumption of growth of the aged-standardized incidence rate, the costs of care management and lost productivity are projected to be $5.85 and $6.47 billion, respectively in 2030, an increase of 56% in each component. The future undiscounted total estimated economic burden for the period 2015-2030 would be $159.44 billion, of which 47.5% will be attributable to care management. Estimates were robust to uncertainty, but the 5-year prevalence of cancer survivorship would account for the greatest variability. Conclusion: Our model showed an upsurge of cancer burden in terms of incidence and the potential economic burden, which may inform cancer control measures.

Levels and predictors of fear and health anxiety during the current outbreak of COVID-19 in immunocompromised and chronic disease patients in Saudi Arabia: A cross-sectional correlational study

“…SA is a leading country with a high prevalence of chronic diseases (ischemic heart disease, hypertension, chronic kidney disease, diabetes, asthma, gastric/peptic ulcer, and cancers) due to rapid economic development, urbanization, smoking, and changes in lifestyle patterns [ 9 – 11 ]. It accounted for 75% of cancer cases in a 12-year cancer prevalence report of Gulf Cooperation Council states and ranked seventh in the world for its diabetes rate [ 12 , 13 ]. However, data on the prevalence of chronic conditions among Saudi patients with COVID-19 have not yet been published.…”

Scholarly Activity of Radiation Oncologists in High-Income Developing Countries: Saudi Arabia as an Example

“… 17 Cancer incidence in SA is estimated to rise by 63% in 2030. 18 The associated economic burden will likely be significant. 18 Notably, about 58% of Saudi nationals are age <30 years, which predicts an increasing demand for cancer care facility expansion in the future.…”

“…The most reported conditions were cardiovascular diseases (15.1%) followed by respiratory diseases (14.16%). An analysis of the cancer registry of patients in the Kingdom during 1999 -2015, has projected an increase in number of cancer cases by 63% by 2030, with a greater proportionate increase in female cases [15].…”
