BACKGROUND: In 2011, a new European Staging System (ESS) for @entity201 ( @entity201 ) was proposed with the expressed purpose of comparing treatment and outcomes data between institutions. The goal of this study was to evaluate the feasibility of ESS data capture. STUDY DESIGN: Forty-seven consecutive @entity1 who underwent surgical resection for @entity201 between 1999 and 2013 were studied. Demographic variables, components of various staging systems (including the ESS), preoperative and perioperative details, pathology, and outcomes were recorded. RESULTS: The mean @entity1 age was 63.2 and 62  % were male. Preoperative imaging included high-resolution CT in all @entity1 , MRI in 34  %, and PET in 11  %. R0 resection was accomplished in 80  % of @entity1 . Four @entity1 (8.5  %) and 18 @entity1 (38.3  %), respectively, received neoadjuvant or adjuvant therapy. During a mean follow-up of 36  months, recurrence rate was 51.3  % and 2- and 5-year survival rates were 69.4 and 33.3  %, respectively. Analysis of data capture found that @entity5 ( @entity5 ) classification was indeterminable in 7/47 @entity1 (14.9  %). For two @entity1 , the form (F) designation had insufficient data. The extent of vascular involvement (PV/HA) was different compared to preoperative imaging in nine @entity1 (19.1  %). The liver remnant volume (V) was calculated in only 18 @entity1 (38.3  %). The @entity409 (D) variable did not account for four @entity1 with @entity32 / @entity82 . In total, only 15 @entity1 (31.9  %) had all required elements to complete the ESS. CONCLUSIONS: Without templated radiology, surgery, and pathology reports, the ESS cannot be applied to current clinical/research practice. Although resection continues to provide significant survival benefit to @entity1 with @entity201 , lack of an accurate prognostic tool for resectability and outcomes continues to be a major impediment to progress in the field.
