Cross-section of tumor and margin cytology. To measure the tumor diameter and margin distance, the sample was cross-sectioned at the section containing the maximum diameter of tumor (top). The margin of this sample revealed malignant positive cytology despite a margin distance of 10 millimeters (bottom). These samples are from case 2 in Table 2.

A case of margin relapse. This patient (case 1 in Table 2) underwent tumor excision for peripheral stage I squamous cell lung cancer (a) with a margin distance of 15 millimeters (b). The patient suffered from margin relapse (c) within 8 months of tumor excision.

Survival by the status of margin cytology. The negative histology group (n = 7) had a 63%, 5-year survival rate, and the positive cytology group (n = 8) had a 43%, 5-year survival rate (p = 0.3).
