Table 5. Histological examination of patients receiving carinal resection and reconstruction with complete pulmonary parenchyma preservation.
| Variables | Overall (n=36) |
|---|---|
| Pathology | |
| Squamous cell carcinoma | 12 (33.3) |
| Adenoid cystic carcinoma | 15 (41.7) |
| Mucoepidermoid carcinoma | 2 (5.6) |
| Atypical carcinoid | 1 (2.8) |
| Stricture | 1 (2.8) |
| Others† | 5 (13.9) |
| Tumor size (cm)‡ | 2.6±1.2 |
| Margin‡ | |
| Negative | 14 (40.0) |
| Positive | 21 (60.0) |
| The length of resected airway (cm)* | 3.2±1.2 |
| For negative margins‡ | 3.0±1.6 |
| For positive margins | 3.3±1.2 |
| Lymph node status‡ | |
| N0 | 29 (82.9) |
| N1 | 2 (5.7) |
| N2 | 4 (11.4) |
Values are presented as n (%) or mean ± standard deviation. †, other pathological diagnoses included schwannoma (n=1, 2.8%), leiomyoma (n=1, 2.8%), inflammatory myofibroblastic tumor (n=1, 2.8%), and atypical hyperplasia (n=2, 5.6%); ‡, one case of stricture was excluded from analysis; *, no significant difference was detected in the length of resected airway between R0 and R1 resections (P=0.559) by Student’s t-test.
