Abstract
Adjuvant chemotherapy for cholangiocarcinoma (CCA) has not been shown to gain significant improvements in survival. Factors contributing to suboptimal treatment response include aggressive disease biology and late clinical presentation. When feasible, surgical resection is the first line of treatment. Yet, recurrence remains high and long-term survival is rare. Neoadjuvant therapy is an appealing approach, with oncologic advantages in allowing the treatment of occult systemic disease and selection of patients most likely to benefit from radical surgery. However, given the surgery-first treatment paradigm for CCA, there is a paucity of data supporting neoadjuvant therapy. This review summarizes the current evidence on treatment response and margin-negative (R0) resection rate associated with neoadjuvant therapy for CCA.
