Zhao JJ, Tan E, Sultana R, Syn NL, Da Zhuang K, Leong S, Tai DWM, Too CW. Intra-arterial therapy for unresectable colorectal liver metastases: A meta-analysis. J Vasc Interv Radiol 2021; 32:1536-1545.e38. [PMID: 34166803 DOI: 10.1016/j.jvir.2021.05.032] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/27/2020] [Revised: 05/09/2021] [Accepted: 05/31/2021] [Indexed: 11/19/2022] Open
Abstract
PURPOSE To evaluate the efficacy of hepatic arterial infusion (HAI), conventional trans-arterial chemoembolization (cTACE), drug-eluting embolic trans-arterial chemoembolization (DEE-TACE), trans-arterial radioembolization (TARE) and their combinations with systemic chemotherapy (SCT) for unresectable colorectal liver metastases. METHODS A search was conducted on EMBASE, Scopus, PubMed and Web of Science for prospective non-randomized studies and randomized controlled trials (RCTs) from inception to 20th June 2020. Survival data of patients were recovered from original Kaplan-Meier curves by exploiting a graphical reconstructive algorithm. One-stage meta-analyses were conducted for median overall survival (OS), survival rates (SR), and restricted mean survival time (RMST), while two-stage meta-analyses of proportions were conducted to determine response rates (RR) and conversion-to-resection rates (CRR). RESULTS 71 prospective non-randomized studies and 21 RCTs were identified comprising 6,695 patients. Among patients treated beyond first line, DEE-TACE+SCT (n=152) had the best survival outcomes of median OS of 26.5 (95%-CI: 22.5-29.1) months and 3-year RMST of 23.6 (95%-CI: 21.8-25.5) months. Upon further stratification by publication year, DEE-TACE+SCT appears to consistently have the highest pooled survival rates at 1-year (81.9%) and 2-years (66.1%) in recent publications (2015-2020). DEE-TACE+SCT and HAI+SCT had the highest pooled-RRs of 56.7% (I2=0.90) and 62.6% (I2=0.87) respectively and pooled-CRRs of 35.5% (I2=0.00) and 30.3% (I2=0.80) respectively. CONCLUSION Albeit significant heterogeneity, paucity of high-quality evidence and the non-comparative nature of all analyses, the overall evidence suggests that patients treated with DEE-TACE+SCT may have the best oncological outcomes and greatest potential to be converted for resection.

Abstract
The liver is the most common anatomical site for hematogenous metastases from colorectal cancer. Therefore effective treatment of liver metastases is one of the most challenging elements in the management of colorectal cancer. However, there is rare available clinical consensus or guideline only focusing on colorectal liver metastases. After six rounds of discussion by 195 clinical experts of the Shanghai International Consensus Expert Group on Colorectal Liver Metastases (SINCE) from 29 countries or regions, the Shanghai Consensus has been finally completed, based on current research and expert experience. The consensus emphasized the principle of multidisciplinary team, provided detailed diagnosis approaches, and guided precise local and systemic treatments. This Shanghai Consensus might be of great significance to standardized diagnosis and treatment of colorectal liver metastases all over the world.

Abstract
Aggressive treatment of colorectal cancer (crc) liver metastases can yield long-term survival and cure. Unfortunately, most patients present with technically unresectable metastases; conventional therapy in such patients consists of systemic therapy. Despite advances in the effectiveness of systemic therapy in the first-line setting, the tumour response rate and median survival remain low in the second-line setting. The preferential blood supply from the hepatic artery to crc liver metastases allows for excellent regional delivery of chemotherapy. Here, we review efficacy and safety data for hepatic artery infusion (hai) pump chemotherapy in patients with metastatic crc from the 5-fluorouracil era and from the era of modern chemotherapy. In selected patients with liver-only or liver-dominant disease who have progressed on first-line chemotherapy, hai combined with systemic agents is a viable therapeutic option when performed at experienced centres. Furthermore, significantly improved survival has been demonstrated with adjuvant hai therapy after liver resection in the phase iii setting. The complication rates and local toxicities associated with hai pump therapy are infrequent at experienced centres and can be managed with careful follow-up and early intervention. The major obstacles to the wide adoption of hai therapy include technical expertise for pump insertion and maintenance, and for floxuridine dose modification. The creation of formal preceptor-focused education and training in hai therapy for interdisciplinary medical professionals might encourage the creation and expansion of this liver-directed approach.

Abstract
Purpose This study evaluated the efficacy of neoadjuvant chemotherapy combining 5-flurouracil/folinic acid with irinotecan (FOLFIRI) in colorectal multiple liver metastases regardless of resectability. Methods Forty-four patients with multiple (at least two) colorectal liver metastases were enrolled at seven tertiary referral hospitals between May 2007 and September 2010. All patients received the FOLFIRI chemotherapeutic regimen. Response to chemotherapy was assessed after three cycles (6 weeks) and once more after six cycles (12 weeks) of treatment. Results Objective response was noted in 27 patients (61.4%) and 4 patients (9.1%) had progressive disease. Of 44 patients, 10 patients (22.7%) underwent curative surgery (R0 resection) and 34 patients did not receive R0 resection. Grades 3 to 4 hematological toxicity was noted in 12 patients (27.3%) and grades 3 to 4 nonhematologic toxicity was identified in 5 patients (11.4%). Conclusion FOLFIRI chemotherapy as a neoadjuvant chemotherapy for multiple colorectal liver metastases regardless of resectability demonstrated the possibility of R0 resection, high rate of objective response, and tolerable toxicities in this study.

Abstract
PURPOSE Bevacizumab has been shown to increase progression free and overall survival in patients with metastatic colorectal cancer. Neoadjuvant bevacizumab is commonly used in patients undergoing liver resection. Our purpose was to evaluate whether bevacizumab is associated with increased rate of perioperative complications in patients undergoing hepatic resection for colorectal liver metastases (CRLM). METHODS Retrospective analysis of patients undergoing hepatic resection for CRLM who received chemotherapy and bevacizumab (group 1, n = 134), or chemotherapy alone (group 2, n = 57). We compared demographics, surgical characteristics, and perioperative course. RESULTS Perioperative complications developed in 35 % of patients in group 1, and 47 % in group 2 (p = 0.11). Of those complications, 15 (11.2 %) in group 1, and 5 (8.8 %) in group 2 were considered major (p = 0.617). Four patients, all of whom received preoperative bevacizumab, developed enteric leaks following combined liver and bowel resection. The rate of anastomotic leak in group 1 was 10 %, compared with 0 in group 2, p = 0.56. CONCLUSION Neoadjuvant chemotherapy along with bevacizumab was not associated with an increased risk of postoperative complications after hepatic resection. Possible association of increased morbidity with simultaneous bowel and liver resections following bevacizumab administration was found and we recommend avoiding such treatment combination.

Abstract
Liver metastasis of colorectal cancer has a high incidence and mortality and is the main factor affecting prognosis, which necessitates the development of more reasonable therapeutic strategy for this condition. Nowadays, surgical resection is the only probable curative method; however, surgical intervention is indicated in only a few patients. The development of medical technology and accumulation of clinical experience have led to the wide use of multimodal treatment for liver metastases of colorectal cancer. Multimodal treatment includes surgical resection, neoadjuvant chemotherapy, transcatheter hepatic arterial chemoembolization, radiation therapy, radiofrequency ablation, cryotherapy, percutaneous ethanol injection, and Chinese medicine treatment. The combined application of the above treatments can improve the survival rate and the quality of life of patients. This article summarizes the advances in comprehensive treatment for colorectal liver metastases.

Abstract
The most common site of metastases in patients with colorectal cancer is the liver. Hepatic resection is considered to be the treatment of choice for liver metastasis from colorectal cancer; however, hepatic resection can be performed in only 20 or 25% of all patients. Recurrence develops in the remnant liver or other organs after hepatic resection in over half of all patients with liver-only metastasis. Hepatic arterial infusion (HAI) chemotherapy can provide relatively high concentrations of drugs to microscopic or macroscopic metastases in the liver, with less toxicity than systemic administration. Meta-analyses have shown HAI chemotherapy to have a significantly higher response rate than systemic chemotherapy and its effect on extrahepatic metastases is negligible. HAI chemotherapy provides much better local control of liver metastases from colorectal cancer than systemic chemotherapy. However, well-controlled studies are needed to elucidate the optimal treatment strategies for neoadjuvant and postoperative adjuvant chemotherapy that optimally combine HAI chemotherapy, molecular targeted agents, and systemic chemotherapy such as FOLFOX or FOLFIRI.

Abstract
Although surgery is the most effective treatment for liver metastases in colorectal cancer patients, only 15-20% of these patients are suitable for a radical surgical approach, and metastases recurrence may occur at follow up. In the last decade, the use of pre-operative chemotherapy in combination with new biological drugs has been introduced. We reviewed data of neo-adjuvant chemotherapy strategies aimed at increasing the resection rate of liver metastases in colorectal cancer patients who were initially considered unresectable.

Abstract
The evolution of chemotherapeutic regimens that include targeted molecular agents has resulted in a breakthrough in the management of advanced colorectal liver metastasis (CLM), improving the progression-free survival after liver resection, and rendering initially unresectable liver tumors resectable, with reported resection rates ranging from 13% to 51%. In addition, the criteria used for selecting patients for hepatectomy have been expanding because of advances in surgical techniques and improvements in chemotherapy. However, the increasing use of chemotherapy has raised concern about potential hepatotoxicities such as steatosis, chemotherapy-associated steatohepatitis, and sinusoidal obstruction syndrome, and their deleterious effects on postoperative outcome. The present review focuses on the advantages and disadvantages of chemotherapy, strategies for the prevention and diagnosis of chemotherapy-associated liver injury, and the adoption of more aggressive surgical approaches, which have changed the traditional paradigm for CLM.

Abstract
PURPOSE OF REVIEW To discuss when and who should get liver resection, how to get to resection and what treatments are useful in the pre or postoperative setting. RECENT FINDINGS Colorectal cancer is a significant problem worldwide, with 49,000 deaths a year in the United States. Sixty percent of patients with metastatic disease will develop liver metastases, and, therefore, the control of liver metastases is an important issue. Liver resections improve survival for these patients, and thus there has been an enthusiasm for getting patients to a point where liver resection is possible. The appropriate timing for resection and how to treat patients before and after resection are important issues. The main themes that will be covered in this review are as follows: who is resectable; adjunctive surgical techniques that can improve resection; how patients with synchronous disease should be dealt with; whether neoadjuvant therapy is useful or harmful for these patients; and when liver resection is contemplated, what is the best approach - perioperative therapy, adjuvant postresection with either systemic or hepatic arterial infusion along with systemic. In unresectable disease, the question is how best to get the patients to resection. SUMMARY This paper will outline some of the flaws in the studies thus far, and problems for the future including a better definition of which patients are resectable, randomized studies comparing perioperative with postoperative therapy and studies comparing systemic therapy with hepatic arterial infusion along with systemic after resection. It is clear that an interdisciplinary team of surgeons, medical oncologists and radiologists is important to improve results for these patients.

Abstract
About 50% of colorectal cancer patients develop liver metastasis, and liver resection is considered the only curative therapy. However, the rate of recurrence is high, which contributes to poor prognosis. Since surgical resection coverage has increased because of improved hepatectomy including portal vein embolization, tumors shrink because of the effectiveness of recent chemotherapy, such as FOLFOX and FOLFIRI, and it has become possible for many patients whose cancer was judged unresectable before to undergo resection. Improvement of new anticancer drugs such as molecularly targeted biologics is greatly changing therapeutic systems of metastatic colorectal cancer, and it is time for us to innovate stage IV therapy. In this report, we will review new treatment strategies for metastatic liver cancer from colorectal cancer, clinical trials of new anticancer drugs for liver metastasis, surgery and ablation as local therapy, and further clarify complex therapeutic systems for metastatic liver tumors from colorectal cancer.

Abstract
BACKGROUND The complete resection of liver metastases from colorectal cancer is the major determinant of longterm survival. The effectiveness of current chemotherapy regimens has made treatment algorithms more flexible and resulted in many different options. Recently, the pathological response to chemotherapy has emerged as another important prognostic marker. Different systems have been used to grade the pathological response in these patients. METHODS This study prospectively evaluates the prognostic value of the pathological response grade (PRG) in liver metastases treated with neoadjuvant chemotherapy. RESULTS Between 2002 and 2006, 50 patients were treated with a sandwich chemotherapy regimen and underwent liver resection. Complete resection was achieved in 45 patients (90%). A strong pathological response to chemotherapy (<10% viable tumour cells in all lesions) was seen in 17 patients (34%). It was associated with a statistically significant longer overall survival (P= 0.019) and was also identified on multivariate analysis as an independent predictor of survival (odds ratio = 243). CONCLUSIONS This pilot study demonstrates the prognostic potential of the PRG, which could be used clinically to select patients for an aggressive multimodal adjuvant algorithm. Larger multicentre studies are required to validate this particular grading system. The keys to longterm survival are resectability and chemo-responsiveness.

Abstract
BACKGROUND Surgery remains the only curative option for patients with colorectal cancer liver metastases (CRLM). Perioperative chemotherapeutic strategies have become increasingly popular in the treatment of CRLM. Although the role of bevacizumab (Bev) in this setting remains unclear, its widespread use has raised concerns about the use of Bev as part of perioperative chemotherapy. METHODS We retrospectively reviewed all patients who received Bev and underwent liver resection between July 2004 and July 2008 at the McGill University Health Center. Chemotherapy-related toxicity, response to chemotherapy, surgical morbidity and mortality, liver function and survival data were assessed. RESULTS A total of 35 patients were identified. Of these, 26 (74.3%) patients received oxaliplatin-based cytotoxic chemotherapy, six (17.1%) received irinotecan-based therapy and the remainder received both agents. A total of 17 patients (48.6%) underwent portal vein embolization prior to resection and 12 (34.3%) underwent staged resection for extensive bilobar disease. A median of six cycles of preoperative Bev were administered. Nine patients (25.7%) experienced grade 3 or higher chemotherapy-related toxicities. Four events were deemed to be related to Bev. The overall response rate was 65.7% (complete and partial response). One patient progressed on therapy, but this did not prevent R0 resection. The incidence of postoperative morbidity was 42.3%. A total of 21.7% of complications were Clavien grade 3 or higher. There were no perioperative mortalities. There were no cases of severe sinusoidal injury or steatohepatitis. The Kaplan-Meier estimate of 4-year survival was 52.5%. CONCLUSIONS These data confirm the safety of chemotherapy regimens which include Bev in the perioperative setting and demonstrate that such perioperative chemotherapy in patients with CRLM does not adversely affect patient outcome. There was no increase in perioperative morbidity compared with published rates. The addition of Bev to standard chemotherapy may improve response rates, which may, in turn, impact favourably on patient survival.

Abstract
OBJECTIVE To assess the resectability rate of patients with initially unresectable liver-only metastases from colorectal cancer (CRC) after treatment with irinotecan/capecitabine. METHODS Patients received irinotecan (240 mg/m(2)) as a 30 min intravenous infusion on day 1 and capecitabine (1000 mg/m(2)) orally bid for 14 days beginning on day 2. Treatment was repeated every 3 weeks. The protocol encouraged two to four cycles of irinotecan/capecitabine after recovery from surgery. RESULTS Between May 2004 and February 2007, 48 patients entered in the study. Forty-seven (97.9%) of the 48 patients were assessable for response. The overall response rate before surgery was 56.3% (95% CI, 42.3-70.3%) in the treated population, including 2 non-confirmed complete response (CR), 18 partial responses (PR) and 7 non-confirmed PR. Twenty-three (47.9%) of 29 patients with tumor shrinkage proceeded to surgical intervention. Twenty of the 23 patients had a complete resection (S-CR). With a median follow-up time of 32 months (range, 24-38 months), the overall median time to progression and overall survival for all patients were 16.7 months (95% CI, 10.0-23.4 months) and 27.5 months (95% CI, 23.6-31.4 months) for all patients. The 1- 2- and 3-year overall survival estimates were 79.2% (95% CI, 67.7-90.7%), 60.4% (95% CI, 46.6-74.3%) and 29.2% (95% CI, 16.3-42.0%), respectively. Grade 3 diarrhea occurred in eight (17.0%) patients. The most common Grade 3/4 hematological adverse event was neutropenia in 8.5% of the patients. There were no treatment-related deaths during this study. CONCLUSIONS Irinotecan/capecitabine appears to be a safe and very effective regimen in selected patients with unresectable liver metastases from CRC, but who are treated with a curative intent.

Abstract
Surgery is the only curative option for patients with liver metastases of colorectal cancer, but few patients present with resectable hepatic lesions. Chemotherapy is increasingly used to downstage initially unresectable disease and allow for potentially curative surgery. Standard chemotherapy regimens convert 10%-20% of cases to resectable disease in unselected populations and 30%-40% of those with disease confined to the liver. One strategy to further increase the number of candidates eligible for surgery is the addition of active targeted agents such as cetuximab and bevacizumab to standard chemotherapy. Data from a phase III trial indicate that cetuximab increases the number of patients eligible for secondary hepatic resection, as well as the rate of complete resection when combined with first-line treatment with the FOLFIRI regimen. The safety profiles of preoperative cetuximab or bevacizumab have not been thoroughly assessed, but preliminary evidence indicates that these agents do not increase surgical mortality or exacerbate chemotherapy-related hepatotoxicity, such as steatosis (5-fluorouracil), steatohepatitis (irinotecan), and sinusoidal obstruction (oxaliplatin). Secondary resection is a valid treatment goal for certain patients with initially unresectable liver metastases and an important end point for future clinical trials.

Abstract
Are presented in this issue, the main oral communications presented at the 4(th) francophone congress on digestive and hepatobiliary surgery and an overview of the symposium that was dedicated to the metastatic colorectal cancer treatment. Colorectal carcinoma is the second leading cause of cancer in Europe and the third cause of cancer death in the United States. Every year in France, 36,000 new cases are diagnosed, 50% of them with visceral metastases. Among these metastasis patients, 70% exhibit liver metastases exclusively at time of diagnosis. In most patients, liver metastases are non resectable, with exclusive chemotherapy offering poor survival. Surgery is the only curative treatment. Among patients with liver metastases, 10 to 20% are resectable with 40% of them surviving at 5 years. The aim of the chemotherapy intensification schedules is to allow resection in 15 to 30% of initially non resectable metastatic patients and consequently offering some long term survivals. Regarding metastatic colorectal cancer treatment, confrontation between oncologists and surgeons is essential in order to give the opportunity to a significant number of metastatic patients to access to cure.

Abstract
INTRODUCTION Over the past decade, the emergence of surgical adjuncts such as portal vein embolization, two-stage hepatectomy, and ablative therapies not only decreases mortality and morbidity after an extended hepatectomy but also broadens the indication for surgical treatment of liver metastasis from colorectal cancer. Combination chemotherapeutic regimens, namely 5-fluorouracil/folinic acid with irinotecan or oxaliplatin, and targeted monochromal antibodies can downsize the tumor burden to the extent that formerly unresectable metastases can sometimes be excised. DISCUSSION The 5-year survival rate following liver resection ranges between 25% and 58%. During the 5-fluorouracil/folinic acid with oxaliplatin and 5-fluorouracil/folinic acid with irinotecan treatment period, the patients who were deemed to be resectable should be considered as surgical candidates regardless of the associated adverse predictive factors. The emergence of epidermal growth factor receptor antibody agents, which act effectively in patients with Kras wild-type tumor, fosters treatment individualization. CONCLUSION The efficacy of the perioperative chemotherapy on survival benefit for resectable liver metastases has not been justified. However, the timing and indication of surgical treatment paradigm in colorectal liver metastasis, including for synchronous disease and extrahepatic disease, are dramatically changing with the development of chemotherapeutic agents.

Abstract
Surgical resection is the most effective treatment modality for liver metastases from colorectal cancer. However, most patients with liver metastases are not candidates for resection due to extensive intrahepatic disease. Approximately one-half of the patients who are able to undergo resection will eventually recur within the remnant liver. Hepatic arterial infusion (HAI) chemotherapy takes advantage of the arterial blood supply of colorectal liver metastases to increase tumor exposure to chemotherapy while minimizing systemic toxicity. HAI chemotherapy has been utilized in patients with unresectable disease in the neoadjuvant setting in an effort to convert them to resectability as well as in patients with resectable disease in the adjuvant setting in an effort to prevent recurrence. This article reviews the roles of HAI chemotherapy in an aggressive approach toward colorectal liver metastases.

Abstract
BACKGROUND Liver resection is the only curative treatment offering a chance of long-term survival in patients with colorectal liver metastases (CRM). Recent data indicated that liver resection in patients with tumor progression while receiving chemotherapy was associated with poor outcome. The aim of the study was to identify risk factors for poor outcome in patients with pre-operative chemotherapy of CRM. METHODS We analyzed 160 patients after liver resection for CRM with preoperative systemic. chemotherapy. Three groups of patients were identified: 44 patients (27.5%) had a tumor response, 20 (12.5%) showed stable disease, and 96 (60%) patients had tumor progression while on chemotherapy. Median follow-up was 2.4 years (range, 6 days-11.1 years). All available clinicopathologic variables possibly associated with outcome were evaluated. RESULTS Survival was 88%, 53%, and 37% at 1, 3, and 5 years. Noncurative resection, carcinoembryonic antigen levels >200 ng/ml, tumor grading, size of the largest tumor >5 cm, and number of metastases were associated with poor patient outcome. In the multivariate analysis, tumor free margin and tumor grading correlated with the outcome. Tumor progression while on chemotherapy had no influence on the long-term survival. CONCLUSION Liver resection offers a long-term survival benefit for patients with CRM, even when tumor growth proceeds during pre-operative chemotherapy.

Abstract
Background Hepatic artery infusion (HAI) is indicated to treat unresectable colorectal hepatic metastases, with recent applications as a neoadjuvant or adjuvant treatment. Traditionally performed with the infusion of fluoropyrimidine-based chemotherapy, it has been now tested with oxaliplatin or irinotecan and associated with systemic chemotherapy. Methods To evaluate the impact of medical devices complications we carried out a search of the published studies on HAI in unresectable colorectal liver metastases. Complications were pooled according to the applied medical system: 1) surgical catheter, 2) radiological catheter, and 3) fully implantable pump. The surgical catheter is inserted into the hepatic artery from the gastro-duodenal artery. The radiological catheter is inserted into the hepatic artery through a percutaneous transfemoral or transaxillar access. The fully implantable pump is a totally internal medical device connected to the arterial hepatic catheter during laparotomy. Results The selection criteria were met in 47/319 studies. The complications of surgical and radiological medical devices connected to a port were found in 16 and 14 studies respectively. Meanwhile, complications with a fully implantable pump were reported in 17 studies. The total number of complications reported in studies evaluating patients with surgical or radiological catheter were 322 (322/948, 34%) and 261 (261/722, 36.1%) respectively. In studies evaluating patients with a fully implantable pump, the total number of complications was 237 (237/1502, 15.8%). In 18/319 studies the number of cycles was reported. The median number of cycles with surgically and radiologically implanted catheters was 8 and 6 respectively. The fully implantable pump allows a median number of 12 cycles. Conclusions The fully implantable pump, maintaining a continuous infusion through the system, allows the lowest risk for thrombosis and infection and the best median number of cycles of loco-regional chemotherapy in HAI.

Abstract
Colorectal cancer (CRC) caused nearly 204,000 deaths in Europe in 2004. Despite recent advances in the treatment of advanced disease, which include the incorporation of two new cytotoxic agents irinotecan and oxaliplatin into first-line regimens, the concept of planned sequential therapy involving three active agents during the course of a patient's treatment and the integrated use of targeted monoclonal antibodies, the 5-year survival rates for patients with advanced CRC remain unacceptably low. For patients with colorectal liver metastases, liver resection offers the only potential for cure. This review, based on the outcomes of a meeting of European experts (surgeons and medical oncologists), considers the current treatment strategies available to patients with CRC liver metastases, the criteria for the selection of those patients most likely to benefit and suggests where future progress may occur.

Abstract
Approximately 50%-60% of patients with colorectal cancers will develop liver lesions in their life span. Despite the potential of surgical resection to provide long-term survival in this subset of patients, only 15%-20% are found to be resectable. The introduction of new neoadjuvant chemotherapeutic agents and the expanding criteria of resection have enhanced the overall 5-year survival from 30% to 60% in the past decade. The use of technical innovations such as staged resection; portal vein embolization, and repeat resection have allowed higher resection rates in patients with bilobar disease. Extrahepatic primary and liver-exclusive recurrent disease no longer represent an absolute contraindication to resection. The role of regional therapy using hepatic arterial infusion is being redefined for liver-exclusive unresectable disease. Adjuvant chemotherapy in combination with regional therapies is being looked at from fresh perspectives. Ablative approaches have gained a firm role both as an adjunct to surgical resection and in the management of patients who are not surgical candidates. Overall, the management of hepatic metastasis from colorectal cancers requires a multimodal approach.

Abstract
Although patients with metastatic colorectal cancer have historically had a uniformly dismal prognosis, recent advances in chemotherapeutics and surgical techniques allow many patients to be treated with the potential for long-term survival and cure. Patients with potentially curable disease are those in whom multidisciplinary strategies including surgery can result in safe resection of all metastatic disease with negative margins. Although favorable outcomes using such strategies can increasingly be predicted, the presence of poor prognostic factors does not necessarily represent a contraindication to the use of a potentially curative strategy as long as a margin-negative resection can ultimately be obtained. Further analysis of the innovative strategies and techniques described in this article are needed to maximize cure rates in patients with this disease.

Abstract
Despite recent advances in the medical treatment of metastatic colorectal cancer (mCRC), which include irinotecan- and oxaliplatin-based first-line regimens, the concept of planned sequential therapy involving three active agents during the course of a patient's treatment and the increasing use of targeted monoclonal antibodies, 5-year survival rates for patients with advanced CRC remain unacceptably low. For patients with CRC liver metastases, liver resection remains the only chance of cure, with 5-year survival rates ranging from 25% to 40%. However, 80% to 85% of patients with stage IV CRC have liver disease which is considered unresectable at presentation. The rapid expansion in the use of improved combination chemotherapy regimens plus or minus biologics, to render initially unresectable metastases resectable has increased the percentage of patients eligible for potentially curative surgery. However, the current staging criteria for CRC patients with metastatic disease do not reflect these recent changes or the fact that there is also a large variation in the survival of patients with stage IV CRC. For example the survival for a patient with a solitary, resectable liver metastasis is better than that for a patient with stage III disease. A new staging system is therefore needed that acknowledges both the improvements that have been made in surgical techniques for resectable metastases and the impact of modern chemotherapy on rendering initially unresectable CRC liver metastases resectable, while at the same time distinguishing between patients with a chance of cure at presentation and those for whom only palliative treatment is possible.

Abstract
The management of advanced colorectal cancer has changed dramatically during the last decade. By redefining resectability, and with the use of modern chemotherapy, nearly 10% of unresectable patients are now alive 5 years after diagnosis, and, overall, 20% are alive at 5 years when the combined results of surgery and chemotherapy are considered. These achievements are not reflected in the current staging, which categorizes all disease spread beyond the lymph node basin of the primary tumor as unstratified stage 4. This article discusses the merits of a number of proposals for a new, meaningful staging system for advanced colorectal cancer.

Abstract
A number of cancers present with synchronous or metachronous hepatic metastases. Historically, many of these patients were considered unresectable and were treated with either systemic chemotherapy or supportive care. Today, a variety of options exist for the management of hepatic metastases. Newer agents for systemic therapy continue to be introduced and are providing improved progression-free and overall survival and increased resectability of liver metastases. However, complete surgical resection of isolated hepatic metastases remains the optimal management for these patients. Surgical interventions can be offered to patients with hepatic-only metastases. Hepatic artery chemotherapy represents an adjunct for those patients undergoing resection and can improve survival. This benefit may be even more pronounced when combined with systemic chemotherapy. Newer generation biologic agents can improve results. New therapeutic modalities to treat lesions that are unresectable include ablative techniques such as radiofrequency ablation (RFA) and cryoablation. This article will examine modalities of diagnosis of hepatic metastases and highlight the data regarding hepatic resection for metastases of several types of primary cancers, the rationale for, and efficacy of, hepatic arterial chemotherapy, in both the postoperative adjuvant setting and in unresectable liver disease, and review the current literature for ablative techniques in the treatment of liver metastases.

Abstract
PURPOSE In patients with unresectable colorectal liver metastases (CLM) resistant to first-line chemotherapy, the impact of cetuximab therapy on resectability is unknown. This study was performed to determine the post-cetuximab resectability rate and to examine postoperative outcomes for these heavily pretreated patients. PATIENTS AND METHODS From February 2004 to April 2006, we evaluated 151 patients with unresectable CLM resistant to initial chemotherapy and subsequently treated with systemic cetuximab. Resectability rates, patient outcomes, and tumoral and nontumoral liver pathology were assessed. RESULTS A total of 27 patients underwent surgery after a median of six cycles of cetuximab + irinotecan (20 of 27), oxaliplatin (four of 27), or both (one of 27). Eighteen patients (67%) had experienced treatment failure after at least two lines of chemotherapy before cetuximab. Twenty-five of the 27 patients who had surgery underwent hepatectomy: nine of 133 patients who were treated completely at our institution (resectability rate, 7%) and 16 of 18 patients who were referred from other institutions after systemic cetuximab therapy. Postoperative mortality was 3.7% (one of 27), with a complication rate of 50%. Histopathologic liver abnormalities were found in nine patients (36%), without specific lesions attributable to cetuximab. After median follow-up of 16 months, 23 of 25 patients who underwent resection (92%) were alive, and 10 patients (40%) were disease free. Median overall (OS) and progression-free survival (PFS) from initiation of cetuximab therapy were 20 and 13 months, respectively. CONCLUSION For CLM refractory to conventional chemotherapy, combination therapy with cetuximab increases resectability rates without increasing operative mortality or liver injury. The median OS and PFS of 20 and 13 months, respectively, suggest that this novel oncosurgical strategy benefits patients with previously refractory disease who respond subsequently to cetuximab.

Abstract
The liver is the most common site of metastatic disease from both gastrointestinal and extra-intestinal malignancies. Historically, only a minority of patients with colorectal liver metastases were candidates for resection. However, over the past several decades, liver resection has evolved as a safe and potentially curative treatment for hepatic colorectal metastases. The development of active chemotherapy and molecular targeted therapies, together with newer modalities like radiofrequency ablation, have expanded the indications for hepatic resection and improved survival. Selected patients with isolated liver metastases from neuroendocrine tumors, germ cell cancers, ocular melanoma, gastrointestinal stromal tumors (GIST), and breast cancer also may be considered for hepatic surgery.

Abstract
OBJECTIVE The purpose of this study was to evaluate the technical advantages, safety, and efficacy of placing a catheter distally in the hepatic artery using a long tapered side-hole catheter with an implantable port for hepatic arterial infusion chemotherapy. SUBJECTS AND METHODS Fifty patients with unresectable malignant liver tumors underwent radiologic implantation of catheter-port systems using the long tapered catheter placement method. A 2.7-French distal shaft of the catheter was inserted distally in the hepatic artery with its side hole located proximally, and a 5-French proximal shaft was placed in the aorta; the catheter tip was not fixed. Technical success, complications including catheter stability and hepatic artery patency, and tumor response were assessed and compared with the following two historical controls: 35 patients with a 5-French catheter inserted simply in the hepatic artery (conventional method), and 131 patients with a 5-French catheter, the tip of which was fixed in the gastroduodenal artery (the fixed-catheter-tip method). RESULTS The technical success rate using the long tapered catheter placement method was 92% (46/50 patients), whereas the feasibility of the fixed-catheter-tip method was confined to 79% of historical controls (131/166 patients). Among patients in whom the gastroduodenal artery was present, a decreased frequency of gastroduodenal artery embolization was seen using the long tapered catheter placement method (39%; 17/44 patients) compared with the conventional method (p = 0.0112) and the fixed-catheter-tip method (p < 0.0001). Cumulative stability rates of the catheter (6 months, 94.9%; 1 year, 94.9%; 2 years, 86.2%) and cumulative patency rates of the hepatic artery (6 months, 89.9%; 1 year, 89.9%; 2 years, 83.5%) were significantly higher using the long tapered catheter placement method than using the conventional method (p = 0.0208 and p = 0.0066, respectively) but were similar to those using the fixed-catheter-tip method. The time of hepatic tumor progression was significantly longer using the long tapered catheter placement method than using the conventional method (p = 0.0299) but was comparable to the time using the fixed-catheter-tip method. CONCLUSION The long tapered catheter placement method should find wider application in hepatic arterial infusion chemotherapy because it is useful in preventing catheter dislodgment and hepatic artery occlusion.

Abstract
Colorectal cancer (CRC) caused nearly 204,000 deaths in Europe in 2004. Despite recent advances in the treatment of advanced disease, which include the incorporation of two new cytotoxic agents irinotecan and oxaliplatin into first-line regimens, the concept of planned sequential therapy involving three active agents during the course of a patient's treatment and the integrated use of targeted monoclonal antibodies, the 5-year survival rates for patients with advanced CRC remain unacceptably low. For patients with colorectal liver metastases, liver resection offers the only potential for cure. This review, based on the outcomes of a meeting of European experts (surgeons and medical oncologists), considers the current treatment strategies available to patients with CRC liver metastases, the criteria for the selection of those patients most likely to benefit and suggests where future progress may occur.

Abstract
BACKGROUND Sixty percent of colon cancer patients develop liver metastasis. Only 25% of those have potentially resectable hepatic metastases, and approximately 58% of those patients relapse. METHODS We review the indications and the technical aspects of hepatic artery infusion (HAI) of chemotherapy, as well as the efficacy, morbidity, and outcomes. RESULTS HAI of chemotherapy has been used following hepatic metastasectomy, in patients with unresectable metastases, or in combination with other agents. Floxuridine, the chemotherapeutic agent most studied, is administered through an implantable subcutaneous infusion pump connected to a surgically placed hepatic artery catheter, which delivers the chemotherapeutic agents at a slow fixed rate. Treatment-related toxicities include chemical hepatitis, biliary sclerosis, and peptic ulceration. Some trials report a survival benefit for HAI over systemic chemotherapy with acceptable toxicity. CONCLUSIONS Regional perfusion chemotherapy can be logistically and technically complicated to deliver. The development of newer systemic agents with superior efficacy in the treatment of metastatic colorectal cancer will likely diminish the role of regional perfusion therapy in the future.

Abstract
BACKGROUND AND AIM Hepatic arterial infusion (HAI) chemotherapy has a number of limitations, including a low rate of complete response and frequent extrahepatic recurrence, in colorectal cancer patients with non-resectable hepatic metastases. METHODS Twenty-nine colorectal cancer patients with non-resectable hepatic metastases were consecutively enrolled for HAI alternating with systemic chemotherapy (HA + SC group). The protocol comprised six cycles of alternating HAI (5-FU + leucovorin for 14 days, and mitomycin C on the first day) and systemic chemotherapy (5-FU + leucovorin). Colorectal cancer patients with two or more hepatic metastases treated using hepatic resection and systemic chemotherapy (HR + SC group) were selected as a comparative group. RESULTS Within the HA + SC group, complete response was achieved in eight patients (28%), whereas 13 patients (45%) showed progressive disease. Six of the eight patients with complete response lived for more than 38 months. Extrahepatic recurrences were more frequent in the HR + SC group than the HA + SC group (47 vs 21%, P = 0.024). The two groups did not differ with respect to overall and hepatic progression-free survival (P = 0.947 and 0.444, respectively), displaying median +/- SE values of 38 +/- 7 and 20 +/- 3 months in the HA + SC group, and 39 +/- 9 and 33 +/- 14 months in the HR + SC group, respectively. One patient in each group experienced toxic hepatitis, and sclerosing cholangitis occurred in one patient of the HA + SC group. Other complications were mostly grade 1 or 2. CONCLUSIONS HAI alternating with systemic chemotherapy led to a promising response and hepatic progression-free survival, possibly reducing extrahepatic recurrence in colorectal cancer patients with non-resectable liver metastases.

Abstract
Patients with bilobar colorectal cancer metastases to the liver present a unique problem in terms of resection. They sometimes require a staged approach to resection that takes advantage of the liver's ability to regenerate, as well as the newer chemotherapeutic agents (e.g., oxaloplatin, irinotecan (CPT-11), and bevacizumab) that have become available. In cases of multiple bilobar metastases, if segment IV is clear of tumor, a left lateral segmentectomy (LLS) can be performed, followed several months later by a formal right hepatectomy. The remnant liver composed of the hypertrophied segment IV is drained by the middle hepatic vein (MHV). In this context, patients with lesions between the origin of the MHV and the inferior vena cava (IVC) present a particularly difficult problem. Conventional excision would require an extended hepatectomy and division of the MHV along with either the right or left hepatic veins (RHV, LHV). This would make it impossible to continue with a formal resection of the remaining lesions in the contralateral liver without sacrificing the sole remaining hepatic vein. We present a novel two-step hepatectomy for lesions between the MHV and the IVC that allows the MHV to be preserved and all lesions to be resected.
