Lung Cancer in Argentina: A Modelling Study of Disease and Economic Burden

TL;DR

This study models the disease and economic burden of lung cancer in Argentina, estimating significant health and financial impacts with detailed cost analysis and uncertainty quantification.

Contribution

It provides the first comprehensive local estimate of lung cancer burden and costs in Argentina using a mathematical model and Monte Carlo simulation.

Findings

Lung cancer caused approximately 10,000 deaths in Argentina in 2023.

The economic burden was estimated at US$ 556.20 million, about 1.4% of healthcare expenditure.

Lung cancer accounted for 10% of total cancer DALYs in Argentina.

Abstract

Objectives: Lung cancer remains a significant global public health challenge and is still one of the leading cause of cancer-related death in Argentina. This study aims to assess the disease and economic burden of lung cancer in the country. Study design: Burden of disease study Methods. A mathematical model was developed to estimate the disease burden and direct medical cost attributable to lung cancer. Epidemiological parameters were obtained from local statistics, the Global Cancer Observatory, the Global Burden of Disease databases, and a literature review. Direct medical costs were estimated through micro-costing. Costs were expressed in US dollars (US$), April 2023 (1 US$ =216.38 argentine pesos). A second-order Monte Carlo simulation was performed to estimate the uncertainty. Results: Considering approximately 10,000 deaths, 12,000 incident cases, and 14,000 5-year prevalent cases, the economic burden of lung cancer in Argentina in 2023 was estimated to be US$ 556.20 million (396.96 -718.20), approximately 1.4% of the total healthcare expenditure for the country. The cost increased with a higher stage of the disease and the main driver was the drug acquisition (80%). 179,046 Disability-adjusted life years could be attributable to lung cancer representing the 10% of the total cancer. Conclusion: The disease and economic burden of lung cancer in Argentina implies a high cost for the health system and would represent 19% of the previously estimated economic burden for 29 cancers in Argentina.
