Hepatic resection beyond barcelona clinic liver cancer indication:When and how

Hepatocellular carcinoma(HCC)is the main common primary tumour of the liver and it is usually associated with cirrhosis.The barcelona clinic liver cancer(BCLC)classification has been approved as guidance for HCC treatment algorithms by the European Association for the Study of Liver and the American Association for the Study of Liver Disease.According to this algorithm,hepatic resection should be performed only in patients with small single tumours of 2-3 cm without signs of portal hypertension(PHT)or hyperbilirubinemia.BCLC classification has been criticised and many studies have shown that multiple tumors and large tumors,as wide as those with macrovascular infiltration and PHT,could benefit from liver resection.Consequently,treatment guidelines should be revised and patients with intermediate/advanced stage HCC,when technically resectable,should receive the opportunity to be treated with radical surgical treatment.Nevertheless,the surgical treatment of HCC on cirrhosis is complex:The goal to be oncologically radical has always to be balanced with the necessity to minimize organ damage.The aim of this review was to analyze when and how liver resection could be indicated beyond BCLC indication.In particular,the role of multidisciplinary approach to assure a proper indication,of the intraoperative ultrasound for intraoperative restaging and resection guidance and of laparoscopy to minimize surgical trauma have been enhanced.

Contrast-enhanced intraoperative ultrasonography equipped with late Kupffer-phase image obtained by sonazoid in patients with colorectal liver metastases

AIM: To find occult metastases during hepatectomy in patients with colorectal cancer liver metastases (CRCLM), contrast-enhanced intraoperative ultrasonography (CE-IOUS) was performed using a new microbubble agent, sonazoid, which provides a parenchyma-specific contrast image based on its accumulation in the Kupffer cells. METHODS: Eight patients with CRCLM underwent CE- IOUS using sonazoid before hepatectomy. The liver was investigated during a late Kupffer-phase imaging, which is a valuable characteristic of sonazoid. RESULTS: CE-IOUS using sonazoid provided the early vascular- and sinusoidal-phase images for 10 min followed by the late Kupffer-phase image up to 30 min after the injection of sonazoid. IOUS did not provide new findings of metastatic lesion in the 8 patients. However, during the late Kupffer-phase image of sonazoid, a metastatic lesion was newly found in two of the 8 patients. These newly detected lesions were removed by an additional hepatectomy and histopathologically diagnosed as a metastasis. CONCLUSION: CE-IOUS using sonazoid can allow surgeons to investigate the whole liver with enough time and to find new metastases intraoperatively.

Proposal of criteria to select candidates with colorectal liver metastases for hepatic resection:Comparison of our scoring system to the positive number of risk factors

AIM： To select accurately good candidates of hepatic resection for colorectal liver metastasis.METHODS： Thirteen clinicopathological features, which were recognized only before or during surgery, were selected retrospectively in 81 consecutive patients in one hospital （Group Ⅰ ）. These features were entered into a multivariate analysis to determine independent and significant variables affecting long-term prognosis after hepatectomy. Using selected variables, we created a scoring formula to classify patients with colorectal liver metastases to select good candidates for hepatic resection. The usefulness of the new scoring system was examined in a series of 92 patients from another hospital （Group Ⅱ ）, comparing the number of selected variables.RESULTS： Among 81 patients of Group Ⅰ, multivariate analysis, i.e. Cox regression analysis, showed that multiple tumors, the largest tumor greater than 5 cm in diameter, and resectable extrahepatic metastases were significant and independent prognostic factors for poor survival after hepatectomy （P 〈 0.05）. In addition, these three factors： serosa invasion, local lymph node metastases of primary cancers, and postoperative disease free interval less than 1 year including synchronous hepatic metastasis, were not significant, however, they were selected by a stepwise method of Cox regression analysis （0.05 〈 P 〈 0.20）. Using these six variables, we created a new scoring formula to classify patients with colorectal liver metastases. Finally, our new scoring system not only classified patients in Group I very well, but also that in Group Ⅱ, according to long-term outcomes after hepatic resection. The positive number of these six variables also classified them well.CONCLUSION： Both, our new scoring system and the positive number of significant prognostic factors are useful to classify patients with colorectal liver metastases in the preoperative selection of good candidates for hepatic resection.

Liver resection for early hepatocellular cancer: Comparison of centers in 3 different countries

AIMTo compare patients who underwent resection of early stage hepatocellular cancer (HCC) in three different countries. METHODSThis retrospective study characterizes 573 stage I/II HCC patients treated with liver resection in 3 tertiary-referral centers: Tokyo (n = 250), Honolulu (n = 146) and Shanghai (n = 177). RESULTSShanghai patients were younger, predominantly male, hepatitis-B seropositive (94%) and cirrhotic (93%). Tokyo patients were older and more likely to have hepatitis-C (67%), smaller tumors, low albumin, and normal alpha-fetoprotein. The Honolulu cohort had the largest tumors and 30% had no viral hepatitis. Age-adjusted mortality at 1 and 5-years were lower in the Tokyo cohort compared to Honolulu and there was no difference in mortality between Shanghai and Honolulu cohorts. Elevated alpha-fetoprotein, low albumin and tumor > 5 cm were associated with increased 1-year mortality. These factors and cirrhosis were independently associated with increased 5-year mortality. Independent risk factors of survival varied when examined separately by center. CONCLUSIONThe profile of early-stage HCC patients is strikingly different across countries and likely contributes to survival differences. Underlying differences in patient populations including risk factors/comorbidities influencing disease progression may also account for variation in outcomes.

Precision surgery for primary liver cancer

Liver resection remains the best curative option for primary liver cancer, such as hepatocellular carcinoma(HCC) and intrahepatic cholangiocarcinoma.In particular, in liver resection for HCC, anatomical resection of the tumor-bearing segments is highly recommended to eradicate the intrahepatic metastases spreading through portal venous branches.Anatomical liver resection,including anatomical segmentectomy and subsegmentectomy using the dye-injection method, is technically demanding and requires experience for completion of a precise procedure.The recent development of imaging studies and new computer technologies has allowed for the preoperative design of the operative procedure, intraoperative navigation, and postoperative quality evaluation of the anatomical liver resection.Although these new technologies are related to the progress of artificial intelligence, the actual operative procedure is still performed as human-hand work.A precise anatomical liver resection still requires meticulous exposure of the boundary of hepatic venous tributaries with deep knowledge of liver anatomy and utilization of intraoperative ultrasonography.

Application of contrast-enhanced intraoperative ultrasonography in the decision-making about hepatocellular carcinoma operation

AIM:To evaluate the detection and differentiation ability of contrast-enhanced intraoperative ultrasonography(CE-IOUS) in hepatocellular carcinoma(HCC) operations.METHODS:Clinical data of 50 HCC patients were retrospective analyzed.The sensitivity,specificity,false negative and false positive rates of contrast enhanced magnetic resonance imaging(CE-MRI),IOUS and CEIOUS were calculated and compared.Surgical strategy changes due to CE-IOUS were analyzed.RESULTS:Lesions detected by CE-MRI,IOUS and CEIOUS were 60,97 and 85 respectively.The sensitivity,specificity,false negative rate,false positive rate of CEMRI were 98.2%,98.6%,98.6%,60.0%,respectively;for IOUS were 50.0%,90.9%,1.8%,1.4%,respectively;and for CE-IOUS were 1.4%,40.0%,50.0%,9.1%,respectively.The operation strategy of 9(9/50,18.0%) cases was changed according to the results of CE-IOUS.CONCLUSION:Compared with CE-MRI,CE-IOUS performs better in detection and differentiation of small metastasis and regenerative nodules.It plays an important role in the decision-making of HCC operation.

Surgical treatment of hepatic metastases from colorectal cancer

Colorectal carcinoma is one of the most frequent cancers in Western societies with an incidence of around 700 per million people.About half of the patients develop metastases from the primary tumor and liver is the primary metastatic site.Improved survival rates after hepatectomy for metastatic colorectal cancer have been reported in the last few years and these may be the result of a variety of factors,such as advances in systemic chemotherapy,radiographic imaging techniques that permit more accurate determination of the extent and location of the metastatic burden,local ablation methods,and in surgical techniques of hepatic resection.These have led to a more aggressive approach towards liver metastatic disease,resulting in longer survival.The goal of this paper is to review the role of various forms of surgery in the treatment of hepatic metastases from colorectal cancer.

Autologous transfusion with modified total hepatic vascular exclusion for extracapsular resection of giant hepatic cavernous hemangioma

BACKGROUND: This paper was to review the effects of intraoperative autologous transfusion during modified, normal-temperature, total hepatic vascular exclusion (THVE) for extracapsular resection of giant hepatic cavernous hemangioma. METHODS: The clinical data from 28 patients, who underwent hepatic resection requiring intraoperative autologous transfusion with the cell-saver apparatus, were analyzed retrospectively. The tumors in the 28 patients involved the proximal hepatic veins and inferior vena cava. The diameters of these hemangiomas ranged from 12x15 cm to 18-40 cm. All patients had varying degrees of THVE. ' RESULTS: The 28 patients with hemangioma received integrated resection and recovered. One patient had rupture of tumors resulting in massive hemorrhage of 6000 ml during liver resection; 4 patients had blood transfusions of 400-800 ml; the other 23 patients had no blood transfusion. Only 6 patients underwent the Pringle maneuver with resection. The other 22 patients underwent THVE during the liver resection. The interval of THVE was 5-30 minutes (mean 16 minutes). CONCLUSIONS: Intraoperative autologous transfusion during modified, normal-temperature THVE for extracapsular resection of huge hepatic cavernous hemangioma is feasible.

Multidisciplinary approach of colorectal cancer liver metastases

Large bowel cancer is a worldwide public health challenge.More than one third of patients present an advanced stage of disease at diagnosis and the liver is the most common site of metastases.Selection criteria for early diagnosis,chemotherapy and surgery have been recently expanded.The definition of resectability remains unclear.The presence of metastases is the most significant prognostic factor.For this reason the surgical resection of hepatic metastases is the leading treatment.The most appropriate resection approach remains to be defined.The two step and simultaneous resection processes of both primary and metastases have comparable survival long-term outcomes.The advent of targeted biological chemotherapeutic agents and the development of loco-regional therapies(chemoembolization,thermal ablation,arterial infusion chemotherapy) contribute to extend favorable results.Standardized evidence-based protocols are missing,hence optimal management of hepatic metastases should be single patient tailored and decided by a multidisciplinary team.This article reviews the outcomes of resection,systemic and loco-regional therapies of liver metastases originating from large bowel cancer.

Simultaneous colorectal and parenchymal-sparing liver resection for advanced colorectal carcinoma with synchronous liver metastases:Between conventional and mini-invasive approaches

The optimal timing of surgery in case of synchronous presentation of colorectal cancer and liver metastases is still under debate.Staged approach,with initial colorectal resection followed by liver resection(LR),or even the reverse,liver-first approach in specific situations,is traditionally preferred.Simultaneous resections,however,represent an appealing strategy,because may have perioperative risks comparable to staged resections in appropriately selected patients,while avoiding a second surgical procedure.In patients with larger or multiple synchronous presentation of colorectal cancer and liver metastases,simultaneous major hepatectomies may determine worse perioperative outcomes,so that parenchymal-sparing LR should represent the most appropriate option whenever feasible.Mini-invasive colorectal surgery has experienced rapid spread in the last decades,while laparoscopic LR has progressed much slower,and is usually reserved for limited tumours in favourable locations.Moreover,mini-invasive parenchymal-sparing LR is more complex,especially for larger or multiple tumours in difficult locations.It remains to be established if simultaneous resections are presently feasible with mini-invasive approaches or if we need further technological advances and surgical expertise,at least for more complex procedures.This review aims to critically analyze the current status and future perspectives of simultaneous resections,and the present role of the available miniinvasive techniques.

Tailoring the area of hepatic resection using inflow and outflow modulation

The performance of hepatic surgery without a parenchyma-sparing strategy carries significant risks for patient survival because of the not negligible occurrence of postoperative liver failure.The key factor of modern hepatic surgery is the use of the intraoperative ultrasound(IOUS),not only to stage the disease,but more importantly to guide resection with the specific aim to maximize the sparing of the functional parenchyma.Whether in patients with hepatocellular carcinoma and underlying liver cirrhosis,or in patients with colorectal liver metastasis,IOUS allows the performance of the so-called "radical but conservative surgery",which is the pivotal factor to offer a chance of cure to an increasing proportion of patients,who until few years ago were considered only for palliative care.Using some new IOUS-guided surgical maneuvers,which are based on the liver inflow and outflow modulations,more precise anatomically subsegmental-and segmentaloriented resections can be effectively performed.The present work describes the rationale and the surgical technique for a precise tailoring of the area of hepatic resection using the most recent attainments in IOUS.Such important technical achievements should be a fundamental part of the surgical armamentarium of the modern liver surgeon.

Conversion of Unresectable to Resectable Liver Metastases from Colorectal Carcinoma Using Hepatic Arterial Chronomodulated Chemotherapy: A Case Report and Short Literature Review

Background: The regional chronomodulated hepatic arterial infusion chemotherapy (HAIC) is an effective regimen for the treatment of patients with unresectable liver metastases from colorectal cancer, especially for the conversion into resectability. Aim: To demonstrate that chronomodulated HAI triplet chemotherapy according to OPTILIV protocol is well tolerated and displayed high antitumor activity in this heavily-pretreated patient. Case Presentation: A 54 years old patient from Russia was treated for a tumor in the ascending colon presented with 13 hepatic metastases ranging from 0.3 to 2.7 cm in diameter. He underwent a laparoscopic right hemicolectomy, 12 cycles of FOLFIRINOX combined to bevacizumab for the last 5 cycles, resulting in a partial response according to CT scan. It was decided to perform a two-stage hepatectomy at Paul Brousse hospital: left partial hepatectomy allowed the excision of 9 lesions. Radio frequency ablation was performed in 2 nodular lesions. Afterwards, the patient received 5 cycles of chronomodulated triplet chemotherapy into the hepatic artery, according to the OPTILIV protocol design, yet without cetuximab, because of the KRAS mutation in the liver metastases, with a partial re-sponse. The patient could then undergo the second stage of the planned right hepatectomy, which turned out to be an R0 resection followed by receiving three courses of chronomodulated HAIC. Disease progression was documented after 3 months. Chronomodulated FOLFIRI chemotherapy was re-started intravenously, in combination with Aflibercept and it was associated with further disease progression. The genetic analysis of our patient’s cancer revealed a high level of MSI. The patient was included in the Phase 2 CheckMate-142 trial and received nivolumab 3 mg/kg every 2 weeks within 3 months. Treatment was discontinued due to ineffectiveness. Then the patient underwent radiotherapy geared towards reduction of pain. Afterwards, the patient died from the disease progression 2 years after the beginning of treatment. Conclusion: In this article, the authors report a clinical case with chronomodulated HAIC as rescue therapy in a heavily pretreated patient with metastatic colorectal cancer, allowing to achieve an objective response despite prior progression on FOLFIRINOX (the same triplet chemo by IV route). This strategy permitted to overcome drug resistance and to perform further complete resection of the liver me-tastases with prolonged patient survival. Thus, chronomodulated HAI is useful in patients with liver metastases from colorectal cancer and de-serves to be further assessed prospectively in clinical trials chemotherapy.

Colorectal liver metastases:An update on multidisciplinary approach

Liver metastasis is the commonest form of distant metastasis in colorectal cancer.Selection criteria for surgery and liver-directed therapies have recently been extended.However,resectability remains poorly defined.Tumour biology is increasingly recognized as an important prognostic factor;hence molecular profiling has a growing role in risk stratification and management planning.Surgical resection is the only treatment modality for curative intent.The most appropriate surgical approach is yet to be established.The primary cancer and the hepatic metastasis can be removed simultaneously or in a two-step approach;these two strategies have comparable long-term outcomes.For patients with a limited future liver remnant,portal vein embolization,combined ablation and resection,and associating liver partition and portal vein ligation for staged hepatectomy have been advocated,and each has their pros and cons.The role of neoadjuvant and adjuvant chemotherapy is still debated.Targeted biological agents and loco-regional therapies(thermal ablation,intra-arterial chemo-or radio-embolization,and stereotactic radiotherapy) further improve the already favourable results.The recent debate about offering liver transplantation to highly selected patients needs validation from large clinical trials.Evidencebased protocols are missing,and therefore optimal management of hepatic metastasis should be personalized and determined by a multi-disciplinary team.

Prognostic factors and time-related changes influence results of colorectal liver metastases surgical treatment:A single-center analysis

AIM:To analyze the prognostic factors involved in survival and cancer recurrence in patients undergoing surgical treatment for colorectal liver metastases(CLM) and to describe the effects of time-related changes on survival and recurrence in these patients.METHODS:From January 1994 to January 2006,236 patients with CLM underwent surgery with the aim of performing curative resection of neoplastic disease at our institution and 189(80%) of these patients underwent resection of CLM with curative intention.Preoperative,intraoperative and postoperative data,including primary tumor and CLM pathology results,were retrospectively reviewed.Patients were divided into two time periods:a first period from January 1994 to January 2000(n = 93),and a second period from February 2000 to January 2006(n = 143).RESULTS:Global survival at 1,3 and 5 years in patients undergoing hepatic resection was 91%,54% and 47%,respectively.Patients with preoperative extrahepatic disease,carcinoembryonic antigen(CEA) levels over 20 ng/dL,more than four nodules or extrahepatic invasion at pathological analysis had worse survival.Tumor recurrence rate at 1 year was 48.3%,being more frequent in patients with preoperative and pathological extrahepatic disease and CEA levels over 20 ng/dL.Although patients in the second time period had more adverse prognostic factors,no differences in overall survival and recurrence were observed between the two periods.CONCLUSION:Despite advances in surgical technique and better adjuvant treatments and preoperative imaging,careful patient staging and selection is crucial to continue offering a chance of cure to patients with CLM.

Radiofrequency ablation versus hepatic resection for breast cancer liver metastasis: a systematic review and meta-analysis

Objective： To evaluate the comparative therapeutic efficacy of radiofrequency ablation （RFA） and hepatic resection （HR） for breast cancer liver metastases （BCLMs）. Methods： Studies that had examined the outcomes for both RFA and HR for BCLM were identified by searching the electronic databases PubMed, EMBASE, and the Cochrane Library. Pooled analyzes of the overall survival （OS）, disease-free survival （DFS）, and short-term outcomes of BCLM were performed. Results： Patients with BCLM gained many more survival benefits from HR than from RFA with regard to the 3-year OS rate （combined odds ratio （OR） 0.41, 95% confidence interval （CI） 0.29-0.59, P〈0.001）, 5-year OS rate （combined OR 0.38, 95% CI 0.32-0.46, P〈0.001）, 3-year DFS （combined OR 0.36, 95% CI 0.27-0.49, P〈0.001）, and 5-year DFS （combined OR 0.51, 95% CI 0.40-0.66, P〈0.001）. RFA had fewer postoperative compli- cations （combined OR 0.30, 95% CI 0.20-0.44, P〈0.001） and shorter hospital stays （combined OR -9.01, 95% CI -13.49-4.54, P〈0.001） than HR. Conclusions： HR takes precedence over RFA in the treatment of patients with BCLM, considering the better survival rate. RFA gives rise to fewer complications and can be carried out with a shorter hos- pital stay, compared to HR. RFA should be reserved for patients who are not optimum candidates for resection.

A new approach to the surgical treatment of parasitic cysts of the liver:Hepatectomy using the liver hanging maneuver

AIM： To review 11 patients with parasitic cysts of the liver, who were treated by hepatic Iobectomy using the liver hanging maneuver （LHM）.METHODS： Between January 2003 and June 2006, we retrospectively analyzed patients who underwent surgical treatment due to parasitic cysts of the liver, at the Ege University School of Medicine, Department of General Surgery. Of these, the patients who underwent hepatic lobectomy using the LHM were reviewed and evaluated for surgical treatment outcome.RESULTS： Over a three-year period, there were 102 patients who underwent surgical treatment for parasitic cysts of the liver. Of these, 11 （10%） patients with parasitic cysts of the liver underwent hepatic Iobectomy using the LHM. Presenting symptoms were abdominal pain, dyspepsia, and cholangitis. Cyst locations were as follows： right lobe filled with cyst, 7 （63%）; segmental location, 2 （18%）; and multiple locations, 2 patients （18%）. All patients underwent hepatic Iobectomy with an anterior approach using the LHM. The intraoperative blood transfusion requirement was one unit for 3 patients and two units for one patient. Postoperative complications included pulmonary atelectasy （2, 18%） and pleural effusion （2, 18%）. No significant morbidity or mortality was observed.CONCLUSION： We concluded that hepatic Iobectomy using the LHM should be considered, not only for hepatic tumors or donor hepatectomy, but also to treat parasitic cysts of the liver.
