Hypothesis
Can a reliable system for selecting patients for lung metastasectomy improve outcomes for melanoma patients?
Conclusion
Surgery can be beneficial for carefully selected melanoma patients with lung metastases, particularly those without risk factors.
Supporting Evidence
- The 5- and 10-year survival rates after complete pulmonary metastasectomy were 22% and 16%, respectively.
- Patients without risk factors had a 5-year survival rate of 29%.
- Those with two risk factors or incomplete resection had a significantly poorer survival rate.
Takeaway
This study found that some melanoma patients with lung metastases can do well after surgery, but only if they meet certain criteria.
Methodology
Data from the International Registry of Lung Metastases was reviewed, and survival was analyzed using Kaplan–Meier estimates and Cox regression.
Potential Biases
Potential selection bias due to the retrospective design and reliance on historical data.
Limitations
The study is limited by its retrospective nature and the long time frame of data collection.
Participant Demographics
Patients who underwent lung metastasectomy for melanoma from 1945 to 1995.
