CAV1 and neoplasm: Table 1 shows the number of cases categorised by tumour differentiation status and tumour sites. It is noticed that LNM-1 had more cases of PD than Tu-1 and Tu-2. Pairwise comparison detected significantly lower Cav-1 expression in LNM-1 compared with Tu-1 samples (n=31, P=0.0002). Analysis of patient clinical information revealed that the WI of Cav-1 inversely correlated with N-stages identified by histology (N positive=N1+N2+N3, n=18, and N negative=N0, n=22, P=0.043), but did not correlate with T-stage, tumour site, patient age, or survival rate.
