Hypothesis
What factors predict long-term survival after lung cancer surgery?
Conclusion
Lung cancer surgery can be performed safely in a county hospital, with age, preoperative stage, and pulmonary function being key predictors of long-term survival.
Supporting Evidence
- The overall 30 days mortality rate was 2.7%.
- 36.3% of patients experienced one or more complications after surgery.
- Median survival time was 3.4 years.
- Age ≥ 70 years predicted reduced long time survival.
- FEV1 < 80% predicted reduced long time survival.
Takeaway
Doctors looked at patients who had lung cancer surgery to see who lived longer. They found that younger patients and those with better lung function did better.
Methodology
Retrospective review of 148 patients who underwent lung cancer surgery from 1993 to 2006, analyzing mortality and complications.
Potential Biases
Potential selection bias due to case selection by surgeons.
Limitations
The study's retrospective design may introduce selection bias, and some advanced cases were referred to other hospitals.
Participant Demographics
Mean age was 67.3 years; 32.4% female and 67.6% male.
Statistical Information
P-Value
p<0.001 for age and p<0.01 for FEV1
Confidence Interval
95% CI: 2.4, 4.5 for median survival time
Statistical Significance
p<0.05
