Via a prospective database, 112 PapCa were identified...PT patients receiving adjuvant gemcitabine chemotherapy featured improved OS (32 vs 13 months; P = .013), whereas gemcitabine tended to be associated with decreased OS in IT patients (35 vs 112 months; P = .193)....PT patients with CK7-positivity or MUC2-negativity were segregated into an even poorer prognostic group.
