Table 5 The comparison of the average relative amount of RCAS1 as assessed by the Western blot method in laryngeal and pharyngeal cancer specimens with respect to the presence of lymph node metastases.
Lymph nodes | N negative (n = 24) | N positive (n = 27) | P |
|---|---|---|---|
RCAS1 average relative amount in cancer (± SD) | 0.984 (± 0.5883) | 1.287 (± 0.5504) | 0.04 |
Average β-Actin relative amount in cancer (± SD) | 1.132 (± 0.532) | 1.282 (± 0.723) | NS |
RCAS1/beta Actin ratio in cancer | 0.862 | 1.003 | - |
RCAS1 average relative amount in clear surgical margin (± SD) | 0.805 (± 0.550) | 0.869 (± 0.483) | NS |
Average β-Actin relative amount in clear surgical margin (± SD) | 1.072 (± 0.473) | 1.192 (± 0.386) | NS |
