Induction chemotherapy with mitomycin, vindesine, and cisplatin for stage III unresectable non-small-cell lung cancer: results of the Toronto Phase II Trial.
OBJECTIVE
The 5-year survival rates with surgical resection for preoperatively identified stage IIIA N2 non-small-cell lung cancer (NSCLC) are less than 10%. A pilot study of mitomycin, vindesine, and cisplatin (MVP) induction chemotherapy was undertaken in an attempt to improve the curative potential of surgery in this group of patients.


METHODS
Thirty-nine patients with mediastinoscopy stage IIIA N2 NSCLC received two cycles of MVP. Responding patients underwent thoracotomy for resection and two further courses of MVP.


RESULTS
The overall response rate was 64% (25 of 39) with three complete and 22 partial responses. Twenty-two patients were resected, which included a radical mediastinal node dissection. Eighteen resections were complete and four were incomplete. Pathologically, three patients (7.7%) had no tumor remaining. Toxicity included two postoperative deaths secondary to a bronchopleural (BP) fistula, mitomycin pulmonary toxicity in two patients, and septic deaths in four patients. Twenty-eight patients have died; 20 have recurrent or progressive disease. Eight of the 18 patients completely resected have recurred, with a median time to recurrence of 20.6 months. Sites of recurrence include two locoregional, five distant (two in brain), and one in both. Median survival of all 39 patients is 18.6 months, with a 3-year survival of 26%. The median survival for those patients completely resected was 29.7 months with a 3-year survival of 40%.


CONCLUSIONS
We conclude (1) that MVP is an effective but toxic chemotherapeutic regimen for limited NSCLC; (2) the median survival seems to be prolonged; and (3) the role of induction chemotherapy followed by surgery in stage IIIA N2 NSCLC requires a phase III randomized trial to compare it with other treatment modalities.
