Lung cancer in Argentina: a modelling study of disease and economic burden.

OBJECTIVES: Lung cancer remains a significant global public health challenge and is still one of the leading causes 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 drug acquisition (80%). A total of 179,046 disability-adjusted life years could be attributable to lung cancer, representing 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.

Appraising failure of surgical and percutaneous revascularization: long term outcomes from an observational registry.

AIM: Many randomized trials have compared coronary artery bypass graft (CABG) and percutaneous coronary intervention (PCI) in terms of efficacy, but data comparing outcomes of patients in which these two techniques have failed are lacking. METHODS: We included patients undergoing PCI at our center between July 2002 and December 2004. Subjects were distinguished in 2 groups: those with at least one occluded or stenotic saphenous vein graft (CABG failure), and those with at least one stent with angiographically documented restenosis (PCI failure). The primary endpoint was the long-term rate of major adverse clinical events. RESULTS: Two hundred and thirthy four patients were included, with a medium follow up of 61±13 months; 134 were assigned to the CABG failure group, and 104 to the PCI failure group, sharing high rates of baseline risk factors. At long term rates of death were higher in post CABG group (22.1% vs. 9.9%; P=0.015, RR 2.24 C.I. 95% 1.14-4.40) while death rates in patients with diagnosis of diabetes mellitus (24.0% vs. 23.5%; P=0.969, RR 1.020 C.I. 95% 0.38-2.74) were not different CONCLUSION: PCI can be safely offered to both these kinds of patients: as recently demonstrated post CABG outcomes seem to be more favorable in patients with diabetes mellitus.
