Abstract

BACKGROUND AND AIM:

Cholangiocarcinoma patients usually have poor treatment outcome and a high mortality rate. The role of adjuvant chemotherapy (AC) is controversial. Our study aimed to evaluate benefits of AC in resectable cholangiocarcinoma patients.

METHODS:

A retrospective study included 263 patients who underwent curative resection in Srinakarind University Hospital. These patients had pathological reports showing a clear margin (R0) or microscopic margin (R1) of lesion-free tissue.

RESULTS:

There were 138 patients who received AC. This group had a significantly lower mean age than patients not receiving adjuvant chemotherapy (NAC) group (57.7 ± 8.5 vs 60.4 ± 9.0 years, P = 0.01). The level of serum albumin above 3 g/dL was more common in AC group than the NAC one (87.7% vs 79.2%, P = 0.04). Patients who received AC had significantly longer overall median survival time (21.6 vs 13.4 months, P = 0.01). Patients with a combination of gemcitabine and capecitabine regimen had the longest survival time (median overall survival time of gemcitabine and capecitabine 31.5, 5-fluorouracil and mitomycin 17.3, 5-fluorouracil alone 22.2, capecitabine alone 21.6, and gemcitabine alone 7.9 months, P = 0.02). Benefits of AC were likely to be found in patients who had high-risk features, that is, high level of carbohydrate antigen 19-9, advanced stage, T4 stage, lymph node involvement, and R1 margin.

CONCLUSIONS:

AC significantly prolongs survival time in resectable cholangiocarcinoma patients, particularly in the high risk group.
