title: Local recurrence after complete resection for non-small-cell carcinoma of the lung. Significance of local control by radiation treatment.
abstract: Of 471 patients undergoing a complete resection for non-small-cell carcinoma of the lung between 1972 and 1989, 40 patients (8.5%) had local recurrences without extrathoracic distant metastasis. Excluding 8 patients who had malignant pleural effusion, we selected 32 patients (24 with hilar-mediastinal lymph node, 6 with bronchial stump, and 2 with chest wall recurrence) from the 40 patients and assessed the significance of local control by radiotherapy. The median length of survival after disease recurrence for these 32 patients was 19 months. Of 29 patients given radiation treatment, 16 who responded to the treatment survived significantly longer than nonresponders (median survival time 27 months versus 6 months, p < 0.01). Univariate analyses of survival after recurrences in relation to various factors revealed that sex and disease-free intervals were significant prognostic factors (p < 0.05) other than the effect of radiotherapy. A multivariate analysis showed that the effect of radiotherapy was the predominant prognostic factor. From these results, we conclude that local control with radiation is beneficial in patients with solely locally recurrent tumors in terms of improved survival.
