Abstract
Background
The role of neoadjuvant chemotherapy (NAC) in the management of intrahepatic cholangiocarcinoma
(ICC) remains unknown. We sought to evaluate our experience treating high-risk ICC
with NAC and to determine the prognostic significance of pathologic response.
Methods
Patients with ICC treated with NAC and surgery were analyzed using a prospectively
maintained database. Pathologic response was graded by a blinded pathologist. Clinicopathologic/treatment
variables were evaluated for associations with survival.
Results
Among 45 patients who received NAC followed by hepatectomy for high-risk ICC, 32(71%)
were considered stage III, and 6(13%) were considered stage IV at time of diagnosis.
Major response was identified in 39% of cases, including 2 with pathologic complete
response. Patients with major response had a longer median NAC duration than patients
with minor response (6 vs 4cycles, P=0.02). Regimen (gemcitabine/cisplatin vs gemcitabine/cisplatin/nab-paclitaxel)
was not associated with response rate. Median recurrence-free (RFS) and overall survival
(OS) were 11 and 45 months. Pathologic response was not associated with improved survival.
Conclusion
Pathologic response to NAC was not associated with survival in this highly selected
cohort. Nonetheless, the extended OS experienced by these high-risk patients is encouraging
and suggests that NAC may help select patients who stand to benefit from aggressive
resection.
