Study design One hundred seventy‐three patients with PC tumours treated at three European centres from 2004 to 2014 were reclassified in three categories: (a) pure SRC cancers (SRC1) (≥90% SRCs); (b) PC carcinoma with SRC component (SRC2) (>10%, <90% SRCs); (c) PC carcinoma not otherwise specified (SRC3) (≤10% SRCs). Results The percentage of SRCs was inversely related to the pT stage (Spearman's ρ = −0.174, P < .001) and the number of positive nodes coded as a continuous variable ( P = .009). Five year cancer‐related survival was significantly higher (58%, 95% confidence interval [CI]: 36%‐75%) in SRC1 compared with SRC2 (39%, 95% CI: 28%‐50%) and SRC3 (38%, 95% CI: 22%‐53%), ( P = .048). In multivariable analysis, the impact of PC categories on cancer‐related survival was significant when controlling for sex, age, pT, pN, and curativity (hazard ratio [HR] of sSRC2 vs SRC1 = 2.08, 95% CI: 1.01‐4.29, P = .046; HR of SRC3 vs SRC1 = 2.38, 95% CI: 1.05‐5.41, P = .039). Conclusion The percentage of SRCs was inversely related to tumour aggressiveness, with long‐term survival significantly higher in SRC1 compared with SRC2 and SRC3 tumours.Show less >
