Key result

The presence of an abdominal aortic aneurysm in lung cancer patients was associated with a significantly higher risk of all-cause mortality compared to matched controls without AAA (adjusted HR 1.14).

Why the study?

Major causes of death in abdominal aortic aneurysm patients are cardiovascular disease and cancer, but the effect of abdominal aortic aneurysm on long-term survival in lung cancer patients was unknown.

Does the presence of an abdominal aortic aneurysm increase all-cause mortality in lung cancer patients?

Population

956 lung cancer patients over 50 years of age with degenerative AAA and 3824 matched controls without AAA

Comparison

Lung cancer patients with AAA vs matched lung cancer patients without AAA

Design

Retrospective matched cohort study using an administrative database

Overview

AAA may raise mortality risk in lung cancer, especially if unrepaired; leaves open whether repair improves outcomes in prospective studies.

Study Design

Type

Cohort (n=4,780)

Structured PICO

Does the presence of an abdominal aortic aneurysm increase all-cause mortality in lung cancer patients?

P
Population
4,780 lung cancer patients aged 50 years and older, with and without degenerative abdominal aortic aneurysm, matched by age, sex, and metastasis, followed for a median of 6.13 years.
E
Exposure
Presence of degenerative abdominal aortic aneurysm (AAA), including untreated, endovascular aneurysm repair (EVAR), and open surgical repair (OSR) subgroups.
C
Comparator
Matched lung cancer patients without AAA (matched 1:4 by age, sex, metastasis, and other comorbidities).
O
Outcome
All-cause mortality rate at median 6.13 years follow-up.hard clinical

Main Result

Hazard Ratio: 1.14 (95% CI 1.06–1.23)

Absolute Event Rate: 57.3% vs 44.8%

p-value: p=<0.001

The presence of an abdominal aortic aneurysm, particularly when untreated, significantly increases the long-term mortality risk in patients with lung cancer, highlighting the need for continuous cardiovascular risk management.

Limitations

  • Retrospective design
  • Uncertainty in the assignment of cancer stage due to the nature of the administrative database
  • Potential confounding variables, including smoking status, comorbidities, and socioeconomic factors, were not comprehensively controlled for
  • Approximately 30% missing data for smoking habit
  • Potential confounding variables (smoking status, comorbidities, socioeconomic factors) not comprehensively controlled

Cite This Study

Kim et al. (2024) conducted a cohort in Lung cancer with or without abdominal aortic aneurysm (n=4,780). Abdominal aortic aneurysm (AAA) vs. Matched lung cancer patients without AAA was evaluated on All-cause mortality (adjusted HR 1.14, 95% CI 1.06-1.23, p=<0.001). The presence of an abdominal aortic aneurysm in lung cancer patients was associated with a significantly higher risk of all-cause mortality compared to matched controls without AAA (adjusted HR 1.14).
