Univariate overall survival analysis for patients with appendiceal adenocarcinoma

^aGrade: 1–well differentiated; 2–moderately differentiated); 3–poorly differentiated.

^bStage: I/II/III–nonmetastatic disease; IVA–well-differentiated intraperitoneal metastatic disease; IVB/IVC–moderate to poorly differentiated metastatic disease.

^cCCS: 0/1 (disease <2.5 mm); 2/3 (disease >2.5 mm).

^dCOX-2: COX-2 expression was assessed using immunohistochemistry.

^eKRAS: KRAS mutation was assessed using polymerase chain reaction-based DNA sequencing.

Abbreviations: CI, confidence intervals; CCS, completeness of cytoreduction score; COX-2, cyclooxygenase-2 expression; NA, not applicable; OS, overall survival.
