Fluorescent Laparoscopic Central Hepatectomy for Liver Cancer Using Indocyanine Green Negative Staining

Laparoscopic hepatectomy is an important treatment method for liver cancer. In the past, the resection boundary was usually determined by intraoperative ...

Hepatocellular carcinoma (HCC) is the most common primary liver cancer and is a highly vascularized solid tumor. Angiopoietin-2 (ANGPT2) has been described as an attractive target for antiangiogenic therapy. Exosomes are small extracellular vesicles secreted by most cell types and contribute to cell-to-cell communication by delivering functional cargo to recipient cells. The expression of ANGPT2 in tumor-derived exosomes remains unknown.

Angiopoietin-2 induces angiogenesis via exosomes in human hepatocellular carcinoma.

Associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) can induce rapid hypertrophy of the liver remnant. However, with a background of liver cirrhosis or other chronic liver diseases, patients with a huge hepatocellular carcinoma (HCC) may sometimes face insufficiency of hepatocellular regeneration after associating liver partition and portal vein ligation for staged hepatectomy (ALPPS). Herein, we report a 56-year-old male with a vast HCC (13.3 × 8.5 × 13 cm) whose ratio of the future liver remnant (FLR)/standard liver volume (SLV) was 28.7% when the disease was first diagnosed. Inadequate hypertrophy of FLR was shown in postoperative volumetric assessment a month after stage I ALPPS. After multidisciplinary team discussion (MDT), the patient was decided to follow three courses of hepatic arterial infusion chemotherapy (HAIC) with oxaliplatin, fluorouracil, and leucovorin (FOLFOX4). The last HAIC was performed together with transhepatic arterial embolization (TAE). Finally, ratio of the FLR/SLV increased from 28.7% to 40% during three-month intervals, meeting the requirements of the surgery. Stage II ALPPS, right trisectionectomy, was then successfully performed. There was no recurrence at half years of follow-up. In our case, HAIC seems to be more potent than transcatheter arterial chemoembolization (TACE) in maintaining the hyperplasia of the liver remnant, reducing tumor load, and preventing tumor progression in patients with a large HCC during ALPPS procedure. HAIC, following the first step of ALPPS, a pioneering treatment modality aiming for inadequate hypertrophy of FLR induced by ALPPS, could be an alternative procedure for patients with a vast HCC in clinical practice.
