Is surgical resection indicated for a solitary non-small cell lung cancer recurrence?

Objectives: Some investigators have reported long-term survival after surgical resection of a solitary non - small cell lung cancer recurrence in various sites. However, the role and indications of the second operation remain unclear. Methods: We reviewed 28 patients with a solitary recurrence after successful initial resection of primary non - small cell lung cancer who underwent resection of the recurrent lesion. The clinicopathologic factors associated with outcome were analyzed. Results: There were 17 men and 11 women. Recurrence resection was performed for the following sites: 16 in the lung, 5 in the brain, 2 in the adrenal gland, and 1 each in the chest wall, stomach, skin, pelvic lymph node, and malar bone. The median survival time was 25 months, and the 1-, 2-, and 5-year survival rates after recurrence were 89%, 59%, and 32%, respectively. Advanced p-stage ( p-stage II and III, n = 14) of the primary tumor was the significant negative prognostic factor. Patients with p-stage II or III had survival equivalent to that of those who had multiple recurrences or were unfit for further surgical intervention. Conclusions: Resection of a solitary non - small cell lung cancer recurrence might provide long-term survival in highly selected patients. However, surgical resection might be contraindicated if the primary tumor is stage II or III.
