    Abstract:
    OBJECTIVE: To evaluate the surgical therapeutic strategy for non-small cell lung cancer (NSCLC) with (N2) mediastinal lymph node metastasis. METHODS: The clinical data of 325 patients with N2 NSCLC treated surgically between 1961 and 1995 were analysed. RESULTS: The over-all 5-year survival rate was 19.6%. Survival was higher in patients with radical resection than with palliative resection, with squamous-cell carcinoma than with adenocarcinoma, with sleeve lobectomy and pneumonectomy than with regular lobectomy, with 1 to 3 mediastinal metastatic lymph nodes than those over 4, and with adjuvant therapy (chiefly postoperative radiotherapy) than without. All these differences were statistically significant (P < 0.05). There was no 5-year survivor in patients with T3 or T4 tumor, nor in those with distant metastasis. CONCLUSION: It is suggested that surgery is the best choice for N2 NSCLC patients with T1 or T2 tumor, with non-adenocarcinoma, and with metastatic mediastinal lymph nodes less than 4 in number. Surgery is probably not a good choice in those with T3 tumor varieties. At operation, radical resection of the tumor and systematic removal of all hilar and mediastinal lymph nodes are essential for disease staging and survival improvement. Adjuvant therapy may improve long-term survival and is especially indicated in patients with residual tumor and/or metastatic mediastinal lymph nodes over 3 in number.
