Summary
Long-term survival for patients with pathologic T3 lung cancer depends on lymph node status and complete resection. Curative resection significantly improves outcomes compared to non-curative approaches.
Area of Science:
- Oncology
- Thoracic Surgery
Context:
- Retrospective analysis of 35 patients with pathologic T3 lung cancer treated between 1983 and 1997.
- Focus on pulmonary resection outcomes.
Purpose:
- To evaluate the prognostic factors influencing long-term survival in patients with pT3 lung cancer.
- To assess the impact of lymph node status and resection completeness on survival rates.
Summary:
- Overall five-year survival rate was 35.8%.
- No significant difference in survival between squamous cell carcinoma and adenocarcinoma.
- Curative resection yielded superior outcomes compared to non-curative resection.
- Five-year survival rates were 46.6% for N0 disease and 22.2% for N1/N2 disease (p < 0.05).
- Tumor invasion site did not significantly affect survival rates.
Impact:
- Lymph node status and completeness of resection are critical determinants of long-term survival in pT3 lung cancer.
- Highlights the importance of surgical technique and nodal staging for patient prognosis.
