SATB1 and neoplasm: Similar findings were obtained when considering SATB1 expression in primary tumours only; with a significantly shorter OS for SATB1 positive PB-cases (logrank p = 0.021) and a difference in response to adjuvant gemcitabine in SATB1 positive cases (8/16 receiving vs 8/16 not receiving adjuvant gemcitabine, logrank p = 0.054) compared with negative cases (39/89 receiving vs 50/89 not receiving adjuvant gemcitabine, logrank p = 0.491) and p(interaction) =0.067.
