Background/Aims: To investigative the potential role of postoperative chemoradiotherapy (CCRT) after R1 resection of intrahepatic cholangiocarcinoma (IHCC).
Methods: Between January 2000 and December 2012, medical records of 18 patients who underwent curative surgery with R1 resection for IHCC were retrospectively reviewed.
Results: Median age was 68 years and 12 patients (66.7%) were male. Median tumor size was 5.0 cm (range, 2.2-11.0) and 12 patients (66.7%) had T3 or higher disease. Lymph nodes were involved in four patients (22.2%). Vascular invasion and perineural invasion were present in 10 (55.6%) and 12 patients (66.7%), respectively. Postoperative CCRT given with 5-fluorouracil or gemcitabine were delivered to 7 patients (38.9%). Median radiation dose was 50.4 Gy (range, 45-54). Univariate analysis showed that median loco-regional recurrence-free survival (LRRFS), progression-free survival (PFS) and overall survival (OS) were prolonged for patients treated with CCRT (median LRRFS; 5.6 months vs. not reached, P<0.001, median PFS; 5.6 vs. 8.3 months, P=0.047, median OS; 15.0 vs. 26.6 months, P=0.064).
Conclusions: Postoperative CCRT improved the loco-regional control and PFS in IHCC patients with R1 resection. Further study is warranted to validate the role of postoperative CCRT for these patients.
