Table 6.
The relationship between number of sites involved by the primary tumour and status of the excision margins and lymph node metastasis
| Single site | Two sites | Multiple sites | Chi square test | |
|---|---|---|---|---|
| Status of excision margins | ||||
| Tumour with >5 mm clearance | 103(63.6) | 22(50.0) | 36(50.0) | |
| Tumour with <1 mm clearance | 45(27.8) | 12(27.3) | 22(30.5) | Single vs two sites = NS |
| Tumour with dysplasia at excision margin/s | 26(16.0) | 08(18.2) | 09(12.5) | Single vs two sites = NS |
| Tumour with 1–5 mm clearance | 22(13.4) | 02(4.5) | 05 (7.0) | Two vs multiple = NS |
| Status of lymph nodes | ||||
| Lymph node metastasis present | 41(21.1) | 10(30.3) | 24(38.0) | |
| Single vs Multiple p = 0.01 | ||||
| Lymph node metastasis absent | 153(78.9) | 23(69.7) | 39(62.0) | Single vs Two NS |
| Two vs Multiple NS |
