Table 6 The comparison of the average relative amount of RCAS1 as assessed by the Western blot in laryngeal and pharyngeal cancer specimens obtained from patients with lymph node metastases with and without the presence of extracapsular spread.
Lymph nodes | The presence of extracapsular spread (n = 16) | No extracapsular spread (n = 11) | P |
|---|---|---|---|
Average relative amount of RCAS1 in cancer (± SD) | 1.4631 (± 0.5285) | 0.8681 (± 0.4362) | 0.0011 |
Average β-Actin relative amount in cancer (± SD) | 1.034 (± 0.731) | 1.102 (± 0.481) | NS |
RCAS1/beta Actin ratio in cancer | 1.414 | 0.787 | - |
RCAS1 average relative amount in clear surgical margin (± SD) | 0.859 (± 0.529) | 0.831 (± 0.500) | NS |
Average β-Actin relative amount in clear surgical margin (± SD) | 1.1806 (± 0.477) | 1.058 (± 0.472) | NS |
RCAS1/beta Actin ratio in clear surgical margin | 0.727 | 0.785 | - |
