No correlation between T, N, or M stage and status or expression of any of the factors was seen, with one exception, where T stage for PACs correlated to QS for E‐cadherin such that all four T1 tumours had low/medium expression of E‐cadherin, whereas one T2 and one T4 PAC were high expressing (P = .050; data not shown). The gene discussed is CDH1; the disease is neoplasm.
