BACKGROUND: This study assessed toxicity, tumor response, disease control, and survival after short-course induction chemoradiotherapy and surgical resection in patients with stage III non-small-cell lung carcinoma. METHODS: Forty-five patients with stage III non-small-cell lung carcinoma received 12-day induction therapy of a 96-hour continuous infusion of cisplatin (20 mg/m2 per day), 24-hour infusion of paclitaxel (175 mg/m2), and concurrent accelerated fractionation radiation therapy (1.5 Gy twice daily) to a dose of 30 Gy. Surgical resection was scheduled for 4 weeks later. Postoperatively, a second identical course of chemotherapy and concurrent radiation therapy (30 to 33 Gy) was given. RESULTS: Induction toxicity resulted in hospitalization of 18 (40%) patients for neutropenic fever. No induction deaths occurred. Of 40 (89%) patients who underwent thoracotomy, resection for cure was possible in 32 (71%) patients. Pathologic response was noted in 21 (47%) patients, and 14 (31%) were downstaged to mediastinal node negative (stage 0, I, or II). At a median follow-up of 19 months, 24 patients were alive, 10 with recurrent disease. Of 21 deaths, 16 were from recurrent disease, three were from treatment, and two were unrelated. Recurrent disease was distant in 21 patients, distant and locoregional in 2, and locoregional in 3. The Kaplan-Meier projected 24-month survival is 49%. Projected 24-month survival is 61% for stage IIIA, 17% for stage IIIB (p = 0.035); 84% for pathologic responders, 22% for nonresponders (p<0.001); 83% for downstaged patients (stage 0, I, or II), 33% for those not downstaged (p = 0.005); and 63% for resectable patients, 14% for unresectable patients (p = 0.007). CONCLUSIONS: We conclude that short-course neoadjuvant therapy with paclitaxel (1) has manageable toxicity and a low treatment mortality, (2) results in good tumor response and downstaging, (3) provides excellent locoregional control with most recurrences being distant, and (4) has improved the median survival compared with historical controls. Survival was better in stage IIIA patients, resectable patients, pathologic responders, and patients downstaged to mediastinal node negative disease (stage 0, I, or II).
