LDLT has played an enormous role in treating early malignant hepatic tumors. But the indication of LDLT for malignant hepatic tumors is based on indefinite criteria. This review summarizes the recent studies in LDLT for treating malignant hepatic tumors. DATA SOURCES: A literature research of the PubMed database was conducted and research articles were reviewed. RESULTS: The current data on LDLT for malignant hepatic tumors, combined with our hospital experience, indicated that if a patient with hepatocellular carcinoma (HCC) who meets with the conventional Milan criteria cannot undergo tumor resection because of poorly preserved liver function, and a cadaveric graft is difficult to obtain within six months, LDLT may be selected. In a patient with recurrence of HCC after conventional therapies, feasibility, optimal timing, and efficacy of LDLT as a second-line treatment should be determined. CONCLUSIONS: Tumor recurrence is related to the biological behavior and staging of the tumor. New immunosuppressors which have anti-tumor effects and inhibit the immune system need to be developed. The indications of LDLT for hepatic malignant tumors should be selected meticulously.展开更多

Despite initial skepticism, improved operative results made laparoscopic approach incorporated to surgical practice and operations increased in frequency and complexity. Evidence supporting LLR comes from case-series, comparative studies and meta-analysis. Despite lack of level 1 evidence, the body of literature is stronger and existing data confirms the safety, feasibility and benefits of laparoscopic approach when compared to open resection. Indications for LLR do not differ from those for open surgery. They include benign and malignant(both primary and metastatic) tumors and living donor liver harvesting. Currently, resection of lesions located on anterolateral segments and left lateral sectionectomy are performed systematically by laparoscopy in hepatobiliary specialized centers. Resection of lesions located on posterosuperior segments(1, 4a, 7, 8) and major liver resections were shown to be feasible but remain technically demanding procedures, which should be reserved to experienced surgeons. Hand-assisted and laparoscopy-assisted procedures appeared to increase the indications of minimally invasive liver surgery and are useful strategies applied to difficult and major resections. LLR proved to be safe for malignant lesions and offers some short-term advantages over open resection. Oncological results including resection margin status and long-term survival were not inferior to open resection. At present, surgical community expects high quality studies to base the already perceived better outcomes achieved by laparoscopy in major centers' practice. Continuous surgical training, as well as new technologies should augment the application of lap-aroscopic liver surgery. Future applicability of new technologies such as robot assistance and image-guided surgery is still under investigation.展开更多
