[Effect of preoperative chemotherapy for bulky N2 non-small-cell lung cancer].
The effect of chemotherapy as the adjuvant therapy to bulky N2 disease (stage IIIA) non-small-cell lung cancer was examined. From January 1992 to December 1996, 464 patients with non-small-cell lung cancer underwent surgery. Seven patients (1.5%) with N2 disease (stage IIIA) received two cycles of preresectional cisplatin and vindesin chemotherapy, followed by standardized surgical resection (Group A). 46 patients (9.9%) had pathological N2 disease (T1-3, M0) after surgery (Group B). In Group A a complete resection was accomplished in two patients (28.6%), and five patients had incomplete resection with a deseased margin, followed thoracic irradiation 60 to 75 Gy. In three patients in Group A the N2 disease was pathologically downstaged to N1 or N0 disease. Overall survival at five years in Group A and in Group B was 48% and 39%, and median survival time was 49 months and 38 months. Although complete resection rate was lower in Group A (28.6%) than in Group B (78.2%), there was no significant difference between five year survival and median survival time in Group A and Group B. These data may be thought to suggest that induction chemotherapy in Group A was effective on occult micrometastatic disease.
