Background:
Unresectable cholangiocarcinoma (CCA) has a dismal prognosis. Initial studies of orthotopic liver transplantation (OLT) alone for CCA yielded disappointing outcomes. The Mayo Clinic demonstrated long-term survival using neoadjuvant chemoradiotherapy followed by OLT in selected patients with unresectable CCA. This study reports the Irish National Liver Transplant Programme experience of neoadjuvant therapy and OLT for unresectable CCA.
Materials And Methods:
Twenty-seven patients with CCA were selected for neoadjuvant chemoradiotherapy in a single centre from October 2004 to September 2011. Patients were given brachytherapy, external beam radiotherapy and 5-fluorouracil (5-Fu), followed by liver transplantation if progression free (20 patients).
Results:
Twenty progression-free patients after neoadjuvant therapy underwent OLT. Hospital mortality was 20%. Of the 16 patients who left hospital, survival rates were 94% and 61% at 1 and 4 years. Seven patients developed recurrent disease and died at intervals of 10-58 months after OLT, whereas 9 are disease free with a median follow-up of 37 months (18-76). Predictors of disease recurrence were a tumour in explant specimen and high CA 19.9 levels.
Discussion:
In selected patients with unresectable CCA, long-term survival can be achieved using neoadjuvant chemoradiotherapy and OLT although short-term mortality is high. Prospective international registries may aid patient selection and refinement of neoadjuvant regimens.
