Аннотация
INTRODUCTION: Cholangiolocellular carcinoma (CoCC) resembles cholangiocellular carcinoma (CCC) and presents a variety of imaging findings; thus, preoperative diagnosis is often difficult.
METHODS: We retrospectively studied patients who were diagnosed with CoCC at the Kansai Rosai Hospital from 2006 to 2021 and treated by laparoscopic liver resection (LLR) or open liver resection (OLR).
RESULT: Among 918 liver resections, 15 patients were diagnosed with CoCC: 11 underwent LLR and 4 OLR. For LLR and OLR, respectively, patient age was 69.9 ± 6.8 and 72.8 ± 10.6, sex was M/F: 10/1 and 2/2, Child-Pugh was A/B/C: 10/1/0 and 4/0/0, liver damage was A/B/C: 8/3/0 and 4/0/0, preoperative diagnosis was CoCC/CCC/HCC: 1/2/8 and 2/2/0, pathological stage of Union for International Cancer Control (UICC) was IA/IB/II/IIIA/IIIB/IV: 8/0/2/1/0/0 and 0/0/3/0/1/0 (p = .0312), and extent of liver resection was Hr0/HrS/Hr1/Hr2/: 3/0/5/3 and 1/1/0/2. In LLR and OLR, respectively, operation time was 417.5 ± 191.0 and 407.5 ± 187.9 min, blood loss was 123.3 ± 217.4 and 1385.0 ± 1038.7 mL, and postoperative hospital stay was 12.2 ± 13.7 and 15.0 ± 6.6 days. For stages I and II/III, respectively, the 5-year disease-free survival rates were 100.0% and 34.3%, and the 5-year overall survival rates were 100.0% and 55.6%. For stage II/III LLR and OLR, respectively, the 3-year disease-free survival rates were 33.3% and 37.5% (p = .8418), and the 5-year overall survival rates were 66.7% and 50.0% (p = .8084).
CONCLUSION: Although further studies are still needed to confirm, minimally invasive liver resection without lymph node dissection is one of a safe and effective approach to the management of CoCC.
