Nodal stage after induction therapy for stage IIIA lung cancer determines patient survival.
Annals of Thoracic Surgery 2000 December
BACKGROUND: This study was undertaken to determine the predictive value of nodal status at resection in regards to long-term outcome of patients undergoing neoadjuvant therapy and resection for stage IIIA N2-positive non-small cell lung cancer (NSCLC).
METHODS: We reviewed the medical records of all patients found on surgical staging to have N2-positive NSCLC and who underwent induction therapy followed by resection between 1988 and 1996 at our hospital. Complete follow-up information was examined utilizing Kaplan-Meier survival analysis and Cox proportional hazards multivariate analysis.
RESULTS: One hundred three patients (59 men) with stage IIIA N2-positive NSCLC received neoadjuvant therapy before surgical resection. Preoperative therapy consisted of platinum-based chemotherapy (76), radiotherapy (18), or chemoradiation (9). Operations included pneumonectomy (38), bilobectomy (6), and lobectomy (59). There were four deaths and seven major complications. Eighty-five patients were followed until death. Median survival among 18 living patients is 60.9 months (range 29 to 121 months). Twenty-nine patients were downstaged to N0 and had 5-year survival of 35.8% (median survival 21.3 months). Seventy-four patients with persistent tumor in their lymph nodes (25 N1 and 49 N2) had significantly worse, 9%, 5-year survival, p = 0.023 (median survival 15.9 months). Other negative prognostic factors were adenocarcinoma and pneumonectomy.
CONCLUSIONS: Patients with N2-positive NSCLC whose nodal disease is eradicated after neoadjuvant therapy and surgery enjoy significantly improved cancer-free survival. These data support surgical resection for patients downstaged by induction therapy; however, patients who are not downstaged do not benefit from surgical resection. Direct effort should be made to improve the accuracy of restaging before resection.
