Hypothesis

Does the count of negative and positive lymph nodes, along with the lymph node ratio, provide better prognostic information for survival in non-small cell lung cancer patients?

Conclusion

Higher counts of negative lymph nodes are associated with better survival outcomes in non-small cell lung cancer patients.

Supporting Evidence

  • NLN count, NPLN, and LNR were identified as independent prognostic indicators.
  • Higher NLN counts were associated with better survival outcomes.
  • Lower NPLN and LNR values indicated worse outcomes.
  • The NLN-based model exhibited the strongest predictive performance.

Takeaway

This study found that having more negative lymph nodes is a good sign for lung cancer patients because it means they are likely to live longer.

Methodology

Data from the SEER 17 Registry Database (2010–2019) was analyzed using Cox regression models to assess the prognostic value of lymph node counts.

Potential Biases

Missing data in the SEER database may introduce bias into the results.

Limitations

The study relies on the SEER database, which may have limitations in accuracy and completeness, lacking clinical staging data and information on comorbidities.
