Adjuvant sorafenib after heptectomy for Barcelona Clinic Liver Cancer-stage C hepatocellular carcinoma patients

AIM: To investigate the efficacy and safety of adjuvant sorafenib after curative resection for patients with Barcelona Clinic Liver Cancer(BCLC)-stage C hepatocellular carcinoma(HCC).METHODS: Thirty-four HCC patients, classified as BCLC-stage C, received adjuvant sorafenib for highrisk of tumor recurrence after curative hepatectomy at a tertiary care university hospital. The study group was compared with a case-matched control group of 68 patients who received curative hepatectomy for HCC during the study period in a 1:2 ratio.RESULTS: The tumor recurrence rate was markedly lower in the sorafenib group(15/34, 44.1%) than in the control group(51/68, 75%, P = 0.002). The median disease-free survival was 12 mo in the study group and 10 mo in the control group. Tumor number more than 3, macrovascular invasion, hilar lymph nodes metastasis, and treatment with sorafenib were significant factors of disease-free survival by univariate analysis. Tumor number more than 3 and treatment with sorafenib were significant risk factors of diseasefree survival by multivariate analysis in the Cox proportional hazards model. The disease-free survival and cumulative overall survival in the study group were significantly better than in the control group(P = 0.034 and 0.016, respectively). CONCLUSION: Our study verifies the potential benefit and safety of adjuvant sorafenib for both decreasing HCC recurrence and extending disease-free and overall survival rates for patients with BCLC-stage C HCC after curative resection.

Associating liver partition and portal vein ligation for staged hepatectomy in the treatment of colorectal cancer liver metastases

Colorectal cancer(CRC)is a common malignancy of the digestive system.Colorectal liver cancer metastasis(CRLM)occurs in approximately 50%of the patients and is the main cause of CRC mortality.Surgical resection is currently the most effective treatment for CRLM.However,given that the remnant liver volume after resection should be adequate,only a few patients are suitable for radical resection.Since Dr.Hans Schlitt first performed the associating liver partition and portal vein ligation for staged hepatectomy(ALPPS)for CRLM in 2012,ALPPS has received considerable attention and has continually evolved in recent years.This review explains the technical origin of the ALPPS procedure for CRLM and evaluates its efficacy,pointing to its favorable postoperative outcomes.We also discuss the patient screening strategies and optimization of ALPPS to ensure long-term survival of patients with CRLM in whom surgery cannot be performed.Finally,further directions in both basic and clinical research regarding ALPPS have been proposed.Although ALPPS surgery is a difficult and high-risk technique,it is still worth exploration by experienced surgeons.
