Patterns of initial disease recurrence after resection of gallbladder carcinoma and hilar cholangiocarcinoma

Abstract

After resection, recurrent GBCA is much more likely than recurrent HCCA to involve a distant site. GBCA is also associated with a much shorter time to recurrence and a shorter survival period after recurrence. The results demonstrated significant differences in the clinical behavior of these tumors and suggested that an adjuvant therapeutic strategy targeting locoregional disease, such as radiotherapy, is unlikely to have a significant impact in the overall management of GBCA. Conversely, there is at least some rationale for such an approach in patients with HCCA based on the pattern of initial recurrence.
