Since the hepatocellular carcinoma (HCC) develops in cirrhotic liver and is often multicentric, liver transplantation (LT) seems to be a rational approach for the treatment of HCC. Current selection criteria of LT for HCC are Milan criteria (single nodule < or = 5 cm , or < or = 3 nodules and Carcinoma, Hepatocellular/etiology/*mortality/*surgery ; Humans ; Liver Cirrhosis/*complications ; Liver Neoplasms/etiology/*mortality/*surgery ; *Liver Transplantation ; Salvage Therapy ; Survival Rate

BACKGROUNDControversial results about the therapeutic value of radiofrequency ablation (RFA) and liver resection (LR) in the treatment of colorectal cancer liver metastasis (CRCLM) have been reported. Thus, we performed the present meta-analysis to summarize the related clinical evidences.

METHODSA systematic literature search was conducted using PubMed (Medline), EMBASE, Cochrane Library, and Web of Science, for all years up to April 2016. Pooled analyses of the overall survival (OS), progression-free survival (PFS), and morbidity rates were performed.

RESULTSA total of 14 studies were finally enrolled in the meta-analysis. Patients treated by LR gained a longer OS and PFS than those of patients treated by RFA. Patients in the RFA group had lower morbidity rates than those of patients in the LR group. Publication bias analysis revealed that there was no significant publication bias in the meta-analysis.

CONCLUSIONSPatients with CRCLM gained much more survival benefits from LR than that from RFA. RFA rendered lower rates of morbidities. More well-designed randomized controlled trails comparing the therapeutic value of LR and RFA are warranted.

OBJECTIVETo explore the significance of resection margin and tumor number on survival of patients with small liver cancer after hepatectomy.

METHODSWe collected 219 cases with small liver cancer undergoing hepatectomy in Cancer Hospital, Chinese Academy of Medical Sciences between December 2003 to July 2013. The survival rates were compared by log-rank test between two resection margin groups (≥ 1 cm vs. <1 cm), different tumor number groups (single tumor vs. multiple tumors). We also performed a multifactor analysis by Cox model.

RESULTSThe 1-, 3-, 5- and 10- year overall survival rates were 95.9%, 85.3%, 67.8% and 53.3%, respectively, in all patients. The median survival time was 28 months in the group of <1 cm resection margin and 36 months in the group of ≥ 1 cm resection margin (P=0.249). The median survival time was 36 months in the group of single tumor and 26 months in the group of multiple tumors (P=0.448). The multifactor analysis also did not show significant effect of resection margin and tumor number on the patients' survival.

CONCLUSIONSFor small liver cancer, the resection margin of 1 cm might be advised. Increasing resection margin in further could probably not improve therapeutic effect. Standardized operation and combined treatment will decrease the negative influence of multiple tumors on overall survival.

UNLABELLEDThe aim of this paper was to study the efficacy, side effects and complications of radiofrequency (RF) ablation of primary and metastatic liver malignancies.

MATERIALS AND METHODSWe retrospectively reviewed 57 patients (39 men, 18 women; mean age, 63 years; age range, 44 to 83 years) who underwent RF ablation for liver malignancies from January 2002 to December 2004. A total of 87 tumours were ablated - 71 (81.6%) hepatocellular carcinomas and 16 (18.4%) metastases (from primaries in the colon, stomach and pancreas). RF ablation was performed either percutaneously (n = 71) under conscious sedation or intraoperatively (n = 16) under general anaesthesia. Follow-up ranged from 1 month to 41 months (mean, 15.2) and included computed tomography (CT) 1 day, 1 month and 3 months after ablation, and half-yearly thereafter. Patients were observed for local tumour progression and for the emergence of new tumours.

RESULTSFour patients with a total of 5 tumours were lost to follow-up. Of the remaining 82 tumours treated, complete ablation was attained in 66 tumours after a single procedure, giving a primary effectiveness rate of 80.5%. Seven (8.5%) required 2 procedures to achieve complete ablation, giving a secondary effectiveness rate of 89% after 2 ablations. One tumour (1.2%) required 3 procedures to achieve complete ablation. One tumour required 4 procedures to date, with the latest follow-up CT still demonstrating incomplete ablation. Two tumours (2.4%) had an initial RF ablation and subsequent transarterial chemoembolisation (TACE). One tumour had an initial RF ablation followed by 32Phosphorus-biosilicon (BrachySil) injection, the latter as part of a Phase IIA trial. One tumour required 2 RF ablations and a subsequent TACE. Lastly, 3 tumours received initial RF ablation but subsequent local tumour progression was not treated as the patients were deemed unfit for repeat ablation. No procedure-related deaths or major complications were encountered. Minor complications were reported in 2 patients (3.8%) - subcapsular haematoma and thermal injury to the adjacent gastric antrum, both not necessitating surgical intervention.

CONCLUSIONSRF ablation is an effective, safe and relatively simple procedure for the treatment of unresectable liver malignancies.

OBJECTIVETo evaluate the influence of sirolimus on the long-term survival of patients after orthotopic liver transplantation (OLT) for hepatocellular carcinoma (HCC).

METHODSClinic data of 165 consecutive patients who underwent OLT for HCC from February 2005 to March 2012 was analyzed retrospectively. Among them, 94 patients were treated with a sirolimus-based immunosuppressive protocol after OLT, while the other 71 patients with a FK506-based protocol. Postoperative survival time, survival, disease-free survival (DFS) and tumor recurrence rates between the two groups were compared.

RESULTSThe 2 groups were comparable in all clinicopathologic parameters. The sirolimus-based group had higher patient survival rates than the control group at 1-year (87% vs. 97%, P = 0.03), 2-year (80% vs. 88%), 3-year (76% vs. 85%) and 5-year (63% vs. 75%). The 1-year, 2-year, 3-year and 5-year recurrence rates were 12% vs. 3%, 17% vs. 9%, 21% vs. 9% (P = 0.04) and 31% vs. 16% (P = 0.03). Early and mid-HCC (I - II stage) of 131 cases (control group 61 cases, sirolimus-based group of 70 patients). The 1-year, 2-year, 3-year and 5-year survival rates were 90% vs. 97% , 80% vs. 90%, 78% vs. 86% and 65% vs. 82% (P = 0.04) and recurrence rates were 10% vs. 3%, 16% vs. 8%, 18% vs. 8% and 29% vs. 11% (P = 0.01).

CONCLUSIONThe sirolimus-based immunosuppressive protocol reduce long-term postoperative recurrence rate and improve the survival rate of patients after OLT for HCC significantly (especially early-mid HCC).

OBJECTIVETo study the methods of surgery for hepatocellular carcinoma (HCC) with tumor thrombi in portal vein (TTPV).

METHODSTo Analyze and summarize the clinical information from 138 HCC patients with tumor thrombi in portal vein collected during January 1990 and January 2003.

RESULTSThirty-seven patients receiving palliative therapy died from 1 to 8 months, and average survival time is 3.9 months. 101 patients had operation treatment, 23 of them underwent hepatoma resection, and average survival time was 10.9 months; 78 patients underwent hepatoma resection and removal of tumor thrombi, and average survival time was 26.8 months. 52 of whom underwent hepatic artery and portal vein chemoembolization, the 1-, 3-, 5-year survival rates was 96.2%, 51.9%, 11.5%, the 1-, 3-, 5-year survival rates of the 26 patients who didn't undergo chemoembolization were 76.9%, 23.1%, 0%.

CONCLUSIONSOperation treatment can comparatively extend the survival time of hepatocellular carcinoma with tumor thrombi in portal vein patients, and the best choice is hepatoma resection and removal of tumor thrombi, hepatic artery and portal vein chemoembolization after operation can enhance the effect.

OBJECTIVETo investigate the effects of Chinese medicine (CM) herbal treatment based on syndrome differentiation on patients with unresectable hepatocellular carcinoma (HCC).

METHODSA total of 94 patients with unresectable HCC were reviewed between June 2008 and June 2011. Survival analysis was performed between patients who received CM with/without non-curative antitumor treatments of Western medicine (WM) (CM group, 30 cases) and patients who were not treated with CM but with non-curative antitumor treatments of WM or supportive treatment alone (non-CM group, 64 cases). Then, survival analysis was performed between patients treated with CM combined with non-curative antitumor treatments of WM (combination therapy group, 25 cases) and patients with non-curative antitumor treatments of WM alone (non-curative antitumor treatments group of WM, 52 cases). The survival analysis was performed by Kaplan-Meier method and prognostic factors for overall survival (OS) were assessed by the Cox proportional hazards regression model.

RESULTSThe median survival time (MST), 1- and 2-year survival rates of the CM group and the non-CM group were 36 months, 76.7%, 56.1% and 12 months, 48.4%, 26.6%, respectively. The Log-rank test revealed significant difference between the two groups in OS (P<0.01). Cox proportional multivariate analysis revealed that CM was an independent favorable prognostic factor for OS. The MST, 1- and 2-year survival rates of combination therapy group and non-curative antitumor treatments group of WM were 36 months, 76.0%, 55.5% and 13 months, 55.8%, 30.8%, respectively. There was significant difference in OS between the two groups (P=0.004).

CONCLUSIONSCM herbs based on syndrome differentiation have positive effects on survival of patients with unresectable HCC. Furthermore, combination therapy of CM and WM are recommended in HCC treatment.

OBJECTIVETo evaluate the efficacy of percutaneous laser ablation (LA) in the treatment for portal vein tumor thrombus (PVTT) of hepatocellular carcinoma (HCC).

METHODSThe PVTT of HCC patients were treated through percutaneous transhepatic laser ablation (PTLA). The survival rate, thrombus size, blood flow of embolized portal vein by thrombus, liver function, ascites and clinical presentation were observed.

RESULTSThe 6-month, 1-year and 2-year survival rate of these 93 patients were 82.8%, 53.0% and 34.1%, respectively. In 11 patients with partially occluded portal vein by PVTT, the cut-surface of the PVTT diminished significantly 6 months after LA. The color blood stream signal was seen again one day after LA in all of the other 82 patients with totally occluded portal vein by thrombus, and it could still be seen in 67 of those one month later, 57 (of 71) 3 months later, 40 (of 57) 6 months later, 27 (of 32) 1 year and 4 (of 6) 2 years later after LA. In the 38 patients who survived over 1 year, PVTT was gradually atrophied and disappeared eventually in 14, PVTT was atrophied and the portal vein changed into honeycomb-like appearance in 14. In the remaining 10 patients, PVTT continued to grow and made the portal vein enlarged. It was also observed that liver function, clinical symptom and ascites were improved in various degree after LA.

CONCLUSIONPercutaneous laser ablation might be an effective and safe treatment method for controlling portal vein tumor thrombus of hepatocellular carcinoma.

INTRODUCTIONVisceral metastases from melanoma represent the poorest prognosis based according to the revised version of the AJCC staging system that recognises both clinical and pathological features distinctive to melanoma. Given that systemic treatments in metastatic melanoma to date remains inadequate, we evaluated the efficacy of surgical metastasectomy on survival outcomes.

MATERIALS AND METHODSBetween year 2000 and 2009, 23 patients with visceral metastases from melanoma were evaluated for metastasectomy. Retrospective review was undertaken of the specific therapy administered following consensus meeting of a multidisciplinary team.

RESULTSThere were 16 males and 7 females. Seventeen patients (74%) had metachronous gastrointestinal/liver metastases following previous treatment of the primary tumour. The median time to development of gastrointestinal/liver metastases, otherwise known as disease-free interval, was 49 (range, 5 to 559) months. Overall median survival period was 9 months, with a 1- and 3-year survival percentages of 39% and 30%, respectively. Survival was influenced by the number of metastases (P = 0.05) and the treatment received (P = 0.03). The disease-free and overall survival periods after metastasectomy were 14 and 21 months, respectively. The 1- and 3-year survival percentages were 60% and 40%, respectively. Patients with single site of metastasis survived longer than patients with more than one site of metastasis (P = 0.005).

CONCLUSIONPatients with visceral metastases from melanoma may derive survival benefit from metastasectomy over systemic therapy. Judicious selection of patients for metastasectomy is paramount for the success of treatment in this group of patients.
