Repeat hepatectomy justified in patients with early recurrence of colorectal cancer liver metastases: A systematic review and meta-analysis. Cancer Epidemiol 2021; 74:101977. [PMID: 34303642 DOI: 10.1016/j.canep.2021.101977] [Citation(s) in RCA: 13] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/28/2021] [Revised: 06/04/2021] [Accepted: 06/27/2021] [Indexed: 12/12/2022]
Abstract
BACKGROUND The benefit of repeat hepatectomy in patients with early recurrence of colorectal cancer liver metastases (CRLM) is questioned, in particular in those suffering from recurrence within three to six months following initial hepatectomy. The aim of this review was therefore to assess whether disease-free interval was associated with overall survival in patients undergoing repeat hepatectomy for recurrent CRLM. METHODS A systematic review and meta-analysis was conducted, according to PRISMA guidelines. PubMed, Embase and Cochrane Library databases were searched from database inception to 6th June 2020. Observational studies describing results of repeat hepatectomy for recurrent CRLM, including (disease-free) interval between hepatic resections and overall survival were included. Patients undergoing repeat hepatectomy within three months or additional resection of extrahepatic disease were excluded from meta-analysis. RESULTS The initial search identified 2159 records, of which 28 were included for qualitative synthesis. A meta-analysis of 15 cohort studies was performed, comprising 1039 eligible patients. Median overall survival of 54.0 months [95 %-CI: 38.6-69.4] was observed after repeat hepatectomy in patients suffering from recurrent CRLM between three to six months compared to 53.0 months [95 %-CI: 44.3-61.6] for patients with recurrent CRLM between seven to twelve months (adjusted HR = 0.89, 95 %-CI: 0.66-1.18; p = 0.410), and 60.0 months [95 %-CI: 52.7-67.3] for patients with recurrent CRLM after twelve months (adjusted HR = 0.70, 95 %-CI: 0.53-0.92; p = 0.012). CONCLUSIONS Disease-free interval is considered a prognostic factor for overall survival, but should not be used as selection criterion per se for repeat hepatectomy in patients suffering from recurrent CRLM.

Abstract
Surgical resection remains a milestone in the treatment of colorectal metastases to the liver. There is a distinct subset of patients who benefit from surgical resection in terms of longer survival or definitive cure. The main effort of the surgical oncological regards the safety of the procedure and the adequacy of the recommendation. Many studies, some of them including multivariate analysis, have shown the presence of prognostic determinants of long-term survival and prognostic indexes of the outcome after hepatectomy. It is now accepted that liver resection should be done when the complete excision of all demonstrable tumor with clear resection margins is feasible. Major contra-indication is represented by the presence of extra-hepatic intra-abdominal disease or of unresectable lung metastatic deposits. There is a wide literature indicating that in very selected patients liver reresection and multiorgan synchronous or metachronous resections are beneficial. The role of neoadjuvant chemotherapy and especially postoperative adjuvant local (intra-hepatic) and systemic chemotherapy is promising and supported by recent multicenter randomised clinical trials.

Abstract
For the 20% of patients with resectable colorectal liver metastases (CRLM), hepatic resection is safe, effective and potentially curative. Factors related to the primary and metastatic tumors individually and in clinical risk-scoring schemes are the best prognostic factors, although it is difficult to define patient groups with resectable, liver-limited CRLM that should be excluded from surgery. Systemic chemotherapy for metastatic colorectal cancer has improved but does not improve overall survival as adjuvant therapy after resection. Conversion to complete resection with systemic and/or hepatic arterial infusion chemotherapy is an appropriate goal for patients with unresectable CRLM.

Safety and outcomes following resection of colorectal liver metastases in the era of current perioperative chemotherapy. J Gastrointest Surg 2013; 17:2133-42.

Abstract
BACKGROUND Preoperative chemotherapy is increasingly utilized in the treatment of colorectal liver metastases (CRLM). Although this strategy may improve resectability, long-term advantages of preoperative chemotherapy for resectable CRLM are less clear. The objective of this study is to report safety and outcomes when perioperative chemotherapy is routinely added to surgery for CRLM. METHODS A retrospective review of patients undergoing liver resections for CRLM during 2003-2011 in single academic oncology center. Demographic data, tumor characteristics, chemotherapy, surgical details, complications and survival were analyzed. RESULTS The study included 157 patients that underwent 168 liver operations. One hundred eighteen patients (70 %) underwent preoperative chemotherapy (75 % oxaliplatin-based). Preoperative portal vein embolization was utilized in 16 (10.1 %) patients. Overall survival (OS) was 89, 57, and 27 % at 1, 3, and 5 years, respectively (median survival-42.8 months). Eleven (7 %) patients had repeat resections for liver recurrence. Thirty-day mortality was 1.26 %, morbidity-24 % (6 %-liver related). Complications were not significantly different in patients that had preoperative chemotherapy. On a multivariate analysis advanced age and >3 lesions predicted poor OS, while advanced age, lesions >5 cm, synchronous lesions, margin-positivity and resection less than hepatectomy were associated with decreased DFS. CONCLUSIONS Our results suggest that even with chemotherapy and resection only a subset of patients remain disease-free after 5 years. However, even in a high-risk patient with multiple lesions, preoperative chemotherapy can be administered safely without apparent increase in postoperative complications. Perioperative chemotherapy should be considered particularly in patients with multifocal or large lesions, synchronous disease and short disease-free interval.

Abstract
BACKGROUND Despite improvements in surgery and chemotherapy, most patients develop recurrence after hepatectomy for metastatic colorectal cancer. Data are lacking on the effect of these patterns on outcome. METHODS A retrospective review of a prospectively maintained hepatobiliary database was performed. Pattern and timing of recurrence and outcome after recurrence were analyzed. Univariate and multivariate analyses of factors associated with outcome after recurrence were carried out. RESULTS From January 1997 through May 2003, a total of 733 patients underwent hepatectomy for colorectal metastases. Of these, 637 patients (87%) were included in the analysis, and in 393 patients (62%), recurrence was documented at the time of last follow-up. Initial recurrence patterns included the following: liver only in 120 patients (31%), lung only in 107 (27%), other single sites in 49 (12%), and multiple sites in 117 (30%). Recurrence occurred within 2 years of hepatectomy in 75% of patients and after 3 years in 11%. Margins at hepatectomy, recurrence pattern, resected recurrence, and disease-free interval from time of colectomy to hepatic metastasis and from time of hepatectomy to recurrence were independently associated with survival as measured from the time of recurrence. Recurrence in the lung, resected recurrence, and time to recurrence after hepatectomy were associated with prolonged survival as measured from the time of hepatectomy and the time of recurrence. CONCLUSIONS The timing and pattern of recurrence after hepatic resection for metastatic colorectal cancer are important predictors of long-term survival.

Abstract
Liver resection is the most effective treatment for primary liver tumours and metastasis to the liver, and remains the only potentially long-term curative therapy for patients with colorectal cancer (CRC) liver metastases. Nevertheless, there is a significant incidence of tumour recurrence following liver resection. Cellular and molecular changes resulting from resection and the subsequent liver regeneration process may influence the kinetics of tumour growth, contributing to recurrence. Although commonly associated with the systemic homeostasis of blood pressure, fluid and electrolyte, the renin-angiotensin system (RAS) has recently been shown to play a role in regulating cell proliferation, apoptosis and angiogenesis in local organs as well as in malignancies. An electronic search of the English literature on the role of the RAS in liver regeneration and tumourigenesis was performed using PubMed, with additional relevant articles sourced from reference lists. Studies have shown that the blockade of the RAS pathway stimulates liver regeneration and inhibits tumour progression. An understanding of the role of RAS in liver regeneration and tumourigenesis may enable alternative strategies to improve patient outcome and survival after liver resection. This review will discuss the role of the RAS in liver regeneration and in tumour recurrence post-liver resection. The potential of the RAS as a novel therapeutic target for CRC liver metastases patients undergoing liver resection will be outlined.

Abstract
Liver resection has clearly been established as the standard treatment for resectable colorectal liver metastases. This article will review the expanding role for hepatectomy in this disease. Faster and safer hepatectomies are allowing combined resections of the primary cancer and synchronous hepatic metastases. Effective neoadjuvant chemotherapy, as well as increasing data demonstrating effectiveness and safety of combined hepatectomy and ablative therapies, have further expanded the pool of patients now selected for resection. The end result is that increasing numbers of patients are undergoing acceptably aggressive surgical therapies with extension of life and possible cure. Successful multimodality therapies are also now allowing for long-term survival even in patients not cured of cancer. The prolonged survival of most patients treated by hepatectomy has allowed a long-term analysis of the patterns of recurrence, which emphasize the importance of controlling liver disease for prolongation of life. These improvements in treatments for hepatic metastases have come with a precipitous escalation of the costs of care. This will likely require that future clinical trials and algorithms of care not only be based on cancer outcome data but also on value analysis of treatment and follow-up regimens.

Abstract
We report a rare case of postoperative colon cancer recurrence who presented with hematuria 13 years after resection of the primary colonic cancer. The patient was 72 years of age and underwent surgical resection of sigmoid colon cancer at another regional hospital in 1994. Since June 2007, this patient has complained of hematuria and bloody stool. On physical examination, tenderness and a hard, indurated mass was palpable in the lower mid-abdomen. Abdominal computed tomography showed a metastatic tumor at the lower midline peritoneum with invasion of the adjacent abdominal wall. Her serum carcinoembryonic antigen level was elevated to 32 ng/dL. Histopathology revealed metastatic colonic adenocarcinoma in the jejunum and abdominal wall.

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
BACKGROUND In the US, systemic chemotherapy is often administered after liver resection for hepatic colorectal metastases, even though no clinical trials data directly support this practice. The bias in America for chemotherapeutic treatment has made studies difficult. Until recently, no well accepted staging systems existed to categorize these patients with liver metastases, who have greatly varied prognoses. STUDY DESIGN All liver resections from an American and from a European tertiary care center performed between 1991 and 1998 were assembled from two prospective databases. Of 792 liver resections, the 518 patients treated with no chemotherapy (379 American, 139 European) were compared with 274 patients treated (240 American, 34 European) with 5-FU-based adjuvant chemotherapy. Patients treated by all other treatment regimens, including regional chemotherapy, were excluded, as were patients who died perioperatively. Patient survival analysis was performed by log-rank, with stratification by the clinical risk score (CRS, a staging system grading risk of recurrence by five clinical parameters: node-positive primary, short disease-free interval, large (> 5 cm) liver tumor, multiple liver tumors, and high carcinoembryonic antigen). RESULTS Patients subjected to adjuvant chemotherapy had improved survival (p=0.007, log-rank test) even after stratification by clinical risk score (p=0.001, stratified log-rank test). In every clinical risk score category, patients subjected to adjuvant chemotherapy had a higher chance of survival (range 1.3 to 2.0 times). Adjuvant chemotherapy was an independent predictor of outcomes. CONCLUSIONS This large study, with patients stratified by risk of recurrence, demonstrates that systemic adjuvant chemotherapy, such as a 5-FU-based regimen, prolongs survival after hepatic resection for colorectal metastases.

Abstract
BACKGROUND Liver parenchyma transection technique using heat coagulative necrosis induced by radiofrequency (RF) energy is evaluated in this series. METHODS Between January 2000 and October 2004, 156 consecutive patients underwent liver resection with the RF-assisted technique. Data were collected prospectively to assess the outcome, including intraoperative blood loss, blood transfusion requirement, and morbidity and mortality rates. RESULTS There were 30 major hepatectomies and 126 minor resections. While total operative time was 241 +/- 89 minutes, the actual resection time was 75 +/- 51 minutes. Intraoperative blood loss was 139 +/- 222 mL. Nine patients (5%) received blood transfusion, predominantly those receiving major hepatectomy (P = .006). Thirty-six patients (23%) developed postoperative complications, and the mortality rate was 3.2%. Mean hospital stay was 12 +/- 12 days. CONCLUSION The RF-assisted technique is associated with minimal blood loss, a low blood transfusion requirement, and reduced mortality and morbidity rates and can be used for both minor and major liver resections.

Abstract
BACKGROUND A 1 cm margin seen at operation is typically the minimally acceptable margin for liver resections. Patients who fail to achieve this margin are routinely treated with edge cryotherapy at our unit. This paper aims to assess the benefit of edge cryotherapy on survival in patients with such suboptimal margins. PATIENTS AND METHODS Between January 1990 and February 2006, 608 patients underwent liver resection and/or cryotherapy for colorectal cancer metastases. All liver resections were performed using the CUSA transection method. Data on marginal status were available for 398 patients. Patient demographics, number and size of liver lesions, preoperative and postoperative carcinoembryonic antigen (CEA), extent of liver resection, margin status, site and date of recurrence, date of last follow-up and death were examined. RESULTS There were 175 patients in the R0 group (>1 cm macroscopic and > or = 1 mm microscopic margin), 103 patients in the R1 group (>1 cm macroscopic and <1 mm microscopic margin) and 120 patients in the R2 group (< or = 1 cm macroscopic margin and received edge cryotherapy). After a median follow-up of 63 months, there were no significant difference between the 5-year survival rates for R0, R1 and R2 (40%, 30% and 28%, respectively). CONCLUSION As long as the surgical margin is clear macroscopically, the microscopic margin width does not affect survival. In patients with suboptimal margins, the addition of edge cryotherapy improves the prospect for long-term survival and may lower recurrence risk.

Abstract
OBJECTIVE The risk of a cancer recurrence has been correlated with the stage of the primary tumour at the time of presentation. However, once a recurrence has developed, the primary tumour stage may not be the determining prognostic factor anymore. The objective of this study was (i) to evaluate the association between the recurrence interval and the outcome of the recurrence, and (ii) to determine whether that interval was affected by the use of adjuvant radiation and/or chemotherapy. METHOD This retrospective study analysed 212 patients who developed recurrent colorectal cancer from 1987 to 1993. Primary parameters such as age, gender, primary tumour site and stage, and use of postoperative adjuvant treatment were correlated with the recurrence interval, the type and site of the recurrence (i.e. locoregional vs distant metastases), and the outcome. Uni- and multivariate analysis was used to compare the recurrence interval and survival between different subgroups as defined by risk factors. RESULTS The mean time between the primary and the recurrent tumour was 25 months (range 1-252 months) with 82% of the recurrences developing within 3 years after surgery. The recurrence interval was inversely correlated with the initial tumour stage. Poor survival was associated with a short recurrence interval (less than 12 months) and a distant recurrence site. Even after adjusting for the initial tumour stage, the use of adjuvant treatment did not prolong the interval, i.e. delay the onset of recurrent cancer. CONCLUSION The recurrence interval of colorectal cancer is a prognostic factor. However, the use of adjuvant therapy did not prolong that interval.

Abstract
IFN-lambda 1, -lambda 2 and -lambda 3 have been discovered as the latest members of the class II cytokine family and shown to possess antiviral activity. Murine B16 melanoma and Colon26 cancer cells were transduced with mouse IFN-lambda to determine whether IFN-lambda possesses antitumor activity. Overexpression of IFN-lambda induced cell surface MHC class I expression and Fas/CD95 Ag, induced significant caspase-3/7 activity, and increased p21(Waf1/Cip1) and dephosphorylated Rb (Ser(780)) in B16 cells in vitro. IFN-lambda expression in tumor cell lines markedly inhibited s.c. and metastatic tumor formation in vivo compared with mock transfections (p < 0.05). Moreover, IFN-lambda expression induced lymphocytic infiltrates, and an Ab-mediated immune cell depletion assay showed that NK cells were critical to IFN-lambda-mediated tumor growth inhibition. Hydrodynamic injection of IFN-lambda cDNA successfully targeted liver metastatic foci of Colon26 cells, and moderately decreased the mortality of mice with tumors. IFN-lambda overexpression in the liver increased NK/NKT cells and enhanced their tumor-killing activity, and suggested the activation of innate immune responses. Thus, IFN-lambda induced both tumor apoptosis and NK cell-mediated immunological tumor destruction through innate immune responses. These findings suggested that local delivery of IFN-lambda might prove a useful adjunctive strategy in the clinical treatment of human malignancies.

Abstract
No consensus on the indications for surgical resection of colorectal liver metastases exists. This systematic review has been undertaken to assess the published evidence for its efficacy and safety and to identify prognostic factors. Studies were identified by computerised and hand searches of the literature, scanning references and contacting investigators. The outcome measures were overall survival, disease-free survival, postoperative morbidity and mortality, quality of life and cost effectiveness, and a qualitative summary of the trends across all studies was produced. Only 30 of 529 independent studies met all the eligibility criteria for the review, and data on 30-day mortality and morbidity only were included from a further nine studies. The best available evidence came from prospective case series, but only two studies reported outcomes for all patients undergoing surgery. The remainder reported outcomes for selected groups of patients: those undergoing hepatic resection or those undergoing curative resection. Postoperative mortality rates were generally low (median 2.8%). The majority of studies described only serious postoperative morbidity, the most common being bile leak and associated perihepatic abscess. Approximately 30% of patients remained alive 5 years after resection and around two-thirds of these are disease free. The quality of the majority of published papers was poor and ascertaining the benefits of surgical resection of colorectal hepatic metastases is difficult in the absence of randomised trials. However, it is clear that there is group of patients with liver metastases who may become long-term disease- free survivors following hepatic resection. Such survival is rare in apparently comparable patients who do not have surgical treatment. Further work is needed to more accurately define this group of patients and to determine whether the addition of adjuvant treatments results in improved survival.

Abstract
Although liver resection offers the only realistic chance of cure for patients with liver metastases from colorectal cancer, no consensus exists as to the procedure of choice for managing these tumors. Data from 193 patients who underwent hepatectomy for liver metastases from colorectal cancer and 26 of 193 patients who underwent repeat hepatectomy for recurrent metastases were collected. The suitability of resection was evaluated retrospectively based on known risk factors for recurrence and patterns of recurrence. On multivariate analysis, a positive surgical margin (SM+) was the only risk factor for recurrence after the initial resection (p < 0.01). SM+ (p < 0.01) and nonanatomic resection (p < 0.05) that was less than a sectionectomy (p < 0.05) were risk factors for recurrence after repeat hepatectomy. Multiple tumors (four or more) was the most common pattern of recurrence after initial hepatectomy, and recurrence close to the line of resection was most common after repeat hepatectomy. Based on tumor doubling times, recurrence after initial hepatectomy seemed to originate from the primary colorectal lesion, whereas recurrence after repeat hepatectomy was derived from a hepatic metastasis. Retrospective analysis suggests that hepatectomy with clear surgical margins is more important than anatomic resection for initial hepatectomy, and at least sectionectomy is necessary for repeat hepatectomy.

Abstract
Although most institutions offer some kind of follow-up to patients operated on for colorectal cancer, its value with respect to prolonged survival has been challenged. However, improved results of liver surgery and chemotherapy make it reasonable to assume that a follow-up programme leading to detection of more asymptomatic recurrences would result in improved survival. Liver metastases and extramural local recurrences are the most common secondary lesions and 5-year survival rates of about 30% are reported after radical resection. From these observations a survival benefit could be expected when follow-up is directed to these forms of recurrence. From six randomized studies, six comparative cohort studies and four meta-analyses it can be concluded that an intensive follow-up programme results in more recurrences being resected for cure and about a 10% higher 5-year survival rate compared with less intensive or no follow-up. However, the differences in the follow-up protocols make it difficult to conclude how a follow-up programme should be designed. Liver imaging and carcinoembryonic antigen assay should probably be included, while the yield of frequent colonoscopies is small. A follow-up regimen based on these principles is suggested. Future studies should focus on which tests are the most cost-effective for follow-up after colorectal cancer resection.

Abstract
We determined the relative value of the metastatic colorectal cancer doubling time as a predictor of recurrence and survival after hepatectomy in comparison with other established predictors. Consecutive patients who underwent hepatic resection ( n = 144) for colorectal cancer liver metastases were studied retrospectively to identify factors that influence overall survival and recurrence in the remnant liver. Overall 5-year survival and nonrecurrence rates were 49.8% and 50.8%, respectively. By multivariate analysis, large liver tumors ( p = 0.038), p53 expression by the liver tumor (p = 0.011), and a short liver metastasis doubling time (< or = 45 days, p = 0.013) negatively affected survival; doubling times > 45 days (adjusted relative risk 0.06; p < 0.001) positively influenced disease-free survival. In patients with remnant liver recurrence, a short doubling time was associated with short disease-free intervals (7.3 +/- 6.2 months), multiple metastases (63.6%), and fewer attempts at repeat hepatectomy (22.7%). The doubling time determines tumor size and reflects the patient's immune and nutritional status. A short doubling time is the most reliable risk factor for multiple metastases, early recurrence, and poor prognosis. Further studies with a larger number of patients are needed to confirm this conclusion.

Abstract
PURPOSE The aim of this study was to assess the value of aggressively treating patients with unresectable liver metastases from colorectal cancer and a poor prognosis. METHODS From 1988 to 1999, 64 patients with unresectable multiple liver metastases from colorectal cancer who had received hepatic arterial infusion chemotherapy were investigated. All patients did not have synchronous extrahepatic metastases at the time of initiating our treatment. When liver metastases were suitable for resection after hepatic arterial infusion chemotherapy, we excised them and repeated prophylactic hepatic arterial infusion chemotherapy as long as possible. We evaluated the efficacy of hepatic arterial infusion chemotherapy by computed tomography and divided these patients into responders and nonresponders. We performed univariate analysis using the log-rank test to calculate predictive factors. In addition, the Cox proportional hazards model was used to perform multivariate analysis of factors related to survival. RESULTS The survival rate of all patients was 67.8 percent after 1 year and 10 percent after 5 years. However, the survival rate for 16 patients who received hepatectomy after hepatic arterial infusion chemotherapy was 35.1 percent after five years. Multivariate analysis demonstrated that the response after hepatic arterial infusion chemotherapy was the most indicative prognostic factor. CONCLUSIONS The prognosis of selected patients who responded to hepatic arterial infusion chemotherapy and received hepatectomy was improved. Applying aggressive treatment as outlined in our strategy may improve the chances of long-term survival.

Abstract
OBJECTIVE To determine the value of repeat liver resection for recurrent colorectal metastases to the liver. SUMMARY BACKGROUND DATA Liver resection represents the best and a potentially curative treatment for metastatic colorectal cancer to the liver. After resection, however, most patients develop recurrent disease, often isolated to the liver. METHODS This study reports the combined experience of repeat liver resection for recurrent liver metastases at an American and a European surgical oncology center. Patients were identified from prospective databases and records were retrospectively reviewed. A total of 126 patients (American n = 96, 1986-2001; European n = 30, 1985-1999) underwent repeat liver resection. Patient characteristics were similar in the two institutions. Median follow-up from first liver resection was 88 and 105 months, respectively. RESULTS Operations performed included 90 minor resections and 36 resections of a lobe or more. The 1-, 3-, and 5-year survival rates were 86%, 51%, and 34%. There were 19 actual 5-year survivors to date. By multivariate regression analysis (proportional hazard model), more than one lesion and tumor size larger than 5 cm were independent prognostic indicators of reduced survival. The interval between the first and second liver resection was not predictive of outcome. CONCLUSIONS Repeat liver resection for colorectal liver metastases is safe. Patients with a low tumor load are the best candidates for a repeat resection. In well-selected patients, further resection of the liver can provide prolonged survival after recurrence of colorectal liver metastases.

Abstract
Despite advances in locoregional chemotherapy, treatment of metastatic liver tumors remains a challenge. Since the liver is the largest organ of the reticuloendothelial system, locoregional immunotherapy would be a reasonable approach for the management of hepatic metastases. Indeed, various immunological approaches have been explored. Regional infusion of cytokines such as interleukin 2 (IL-2) or tumor necrosis factor-alpha (TNF-alpha) through the hepatic artery or the portal vein has been combined with chemotherapy and demonstrated to be better than chemotherapy alone. Locoregional adaptive immunotherapy (AIT) using lymphokine-activated killer (LAK) cells or tumor-infiltrating lymphocytes (TIL) has also been tried with rather disappointing responses. Addition of immunostimulants such as OK-432 to AIT increased clinical responses. Recently, several new approaches have emerged to improve the outcome of locoregional immunotherapy. Embolization of melanoma metastatic to the liver with a granulocyte-macrophage colony-stimulating factor (GM-CSF)/ethiodized oil emulsion resulted in control of liver metastases, as well as development of significant immune responses in remote extrahepatic metastases. A gene therapy designed to introduce foreign major histocompatibility complex (MHC) molecules in colorectal metastases has proven to be a safe and feasible approach. Larger scale clinical trials are mandatory to define the role of locoregional immunotherapy for metastatic tumors in the liver.

Abstract
OBJECTIVE The aim of this study is to determine the absolute contraindication for hepatic resection for colorectal metastases and investigate the value of hepatectomy for gastric metastases by comparing it with the results of colorectal metastases performed with the same criteria. METHODS A retrospective cohort study was conducted in patients undergoing hepatic resection for metastatic colorectal (n = 64) and gastric (n = 17) carcinomas. Common predictive factors for both metastases were analyzed by the stratified Cox proportional hazard model. In this model, the different baseline hazard was set for each disease, whereas the risk of each covariate was assumed to be equal in both gastric and colorectal metastases. RESULTS Overall 1-, 2-, and 5-yr survival rates after hepatectomy for colorectal and gastric metastases were 90%, 73%, 42%, and 47%, 22%, 0%, respectively. Factors controlling prognosis were as follows: age > or = 60, extrahepatic metastases, serosal invasion, grade of lymph node metastases, tumor cell differentiation of the primary lesion(s), carcinoembryonic antigen level, tumor-exposed surgical margin, and blood transfusion. In particular, presence of extrahepatic metastases showed the markedly high-risk ratio among these eight variables. CONCLUSIONS Hepatectomy, if possible, is indicated in patients with hepatic metastases from colorectal carcinoma if there are no extrahepatic metastases and if the primary disease is controlled. It is indicated only in carefully selected patients with metastases from gastric carcinoma.

Abstract
The liver is a common site of metastasis from a variety of tumors. In many cases, liver resection for metastatic cancer provides the only chance for a cure and can be performed with less than 5% mortality and acceptable morbidity. The 5-year survival following liver resection for colorectal metastasis is reported in many large series to be 25% to 37%. The data regarding liver resection for other metastatic tumor types are less clear. However, resection for selected tumors, such as neuroendocrine and renal cell, can provide durable palliation and/or cure. We will review important prognostic factors used to guide the selection of patients for resection of metastatic disease and make recommendations for imaging studies and follow-up routines. The role of adjuvant regional and systemic chemotherapy for resectable metastatic disease is also discussed. Methods for ablating unresectable metastatic tumors may prove to be useful adjuncts to current therapies.

Abstract
BACKGROUND Liver resection is currently accepted as the only potential cure for patients with metastases of colorectal tumors in the liver. However, cancer will recur in more than 70% of patients. METHODS In the 7 years to December 1997, 60 patients underwent liver resections for colorectal metastases at our institute. Of these, 20 patients had repeated surgical resections for recurrent disease of the liver and other organs. Another 2 patients had undergone previous hepatectomy elsewhere. The clinical data for these patients were reviewed. RESULTS The median interval between the 2 resections was 16 months. Eighteen hepatectomies, 6 lung resections, and 1 pancreatoduodenectomy were performed in 22 patients. Operative mortality and complication rates were 0% and 18%, respectively. At a median follow-up of 25 months after repeated resection, the survival rate in these patients was 73% at 2 years (12 of 16 evaluable patients are surviving) and 22% at 5 years (2 of 10 evaluable patients are surviving); the median survival time was 44 months. CONCLUSIONS Repeated resections for recurrent colorectal metastases yield comparable results to first liver resections in operative mortality and morbidity rates, survival time, and pattern of recurrence. Although the number of patients surviving more than 5 years is still limited, the absence of other proven treatments supports the concept of an aggressive resectional approach for these patients.

Abstract
Surgical resection is the mainstay of treatment for malignant liver tumours and offers the only chance of cure. Advances in radiological imaging, surgical technique and peri-operative management have enabled liver resection to be performed safely. Partial hepatectomy is indicated for the treatment of hepatocellular carcinoma and hepatic metastases from colorectal cancer. In addition, it may be utilized for selected patients with liver metastases from other primary tumours. Total hepatectomy with transplantation may be of benefit in some patients with unresectable neuroendocrine metastases or small hepatocellular carcinomas. The role of cryosurgery has not been precisely defined, and it needs to be compared with other palliative therapies such as ethanol injection and hepatic artery embolization.

Abstract
OBJECTIVE To assess the value of diagnostic laparoscopy (DL) and laparoscopic ultrasonography (LUS) in the staging and selection of patients with colorectal liver metastasis. SUMMARY BACKGROUND DATA Preoperative imaging modalities such as ultrasound, computed tomography, and magnetic resonance imaging are limited in the assessment of the number and exact location of hepatic metastases and in the detection of extrahepatic metastatic disease. Consequently, the surgeon is often faced with a discrepancy between preoperative imaging results and perioperative findings, resulting in either a different resection than planned or no resection at all. METHODS Fifty consecutive patients were planned for DL and LUS in a separate surgical sitting to assess the resectability of their liver metastases. All patients were considered to be candidates for resection on the basis of preoperative imaging studies. RESULTS Laparoscopy could not be performed in 3 of the 50 patients because of dense adhesions. The remaining 47 patients underwent DL. On the basis of DL and LUS, 18 (38%) patients were ruled out as candidates for resection. Of the 29 patients who subsequently underwent open exploration and intraoperative ultrasonography, another 6 (13%) were deemed to have unresectable disease. CONCLUSIONS The combination of DL and LUS significantly improves the selection of candidates for resection of colorectal liver metastases and effectively reduces the number of unnecessary laparotomies.

Abstract
OBJECTIVE To determine the impact of adjuvant hepatic arterial infusion (HAI) on survival relative to resection alone in patients with radical resection of colorectal liver metastases. SUMMARY BACKGROUND DATA Nearly 40% to 50% of all patients with colorectal carcinoma develop liver metastases. Curative resection results in a 5-year survival rate of 25% to 30%. Intrahepatic recurrence occurs after a median of 9 to 12 months in up to 60% of patients. The authors hypothesized that adjuvant intraarterial infusion of 5-fluorouracil (5-FU) might decrease the rate of intrahepatic recurrence and improve survival in patients with radical resection of colorectal liver metastases. METHODS Between April 5, 1991, and December 31, 1996, patients with colorectal liver metastases from 26 hospitals were stratified by the number of metastases and the site of the primary tumor and randomized to resection of the liver metastases followed by adjuvant HAI of 5-FU (1000 mg/m2 per day for 5 days as a continuous 24-hour infusion) plus folinic acid (200 mg/m2 per day for 5 days as a short infusion), or liver resection only. RESULTS The first planned intention-to-treat interim analysis after inclusion of 226 patients and 91 events (deaths) showed a median survival of 34.5 months for patients with adjuvant therapy versus 40.8 months for control patients. The median time to progression was 14.2 months for the chemotherapy group versus 13.7 months for the control group. Grade 3 and 4 toxicities (World Health Organization), mainly stomatitis (57.6%) and nausea (55.4%), occurred in 25.6% of cycles and 62.9% of patients. CONCLUSION According to this planned interim analysis, adjuvant HAI, when used in this dose and schedule in patients with resection of colorectal liver metastases, reduced the risk of death at best by 15%, but at worst the risk of death was doubled. Thus, the chance of detecting an expected 50% improvement in survival by the use of HAI was only 5%. Patient accrual was therefore terminated.

Abstract
BACKGROUND Approximately 20-40% of patients who undergo liver resection for colorectal metastases develop recurrent disease confined to the liver. The goals of this study were to determine whether the survival benefit of repeat hepatic resection justified the potential morbidity and mortality. METHODS A retrospective review was performed on all patients who underwent liver resection for colorectal cancer metastases between 1983 and 1995 (N = 202). Repeat liver resections were performed on 23 patients for recurrent metastases. RESULTS There were no operative deaths in the 23 patients, and the postoperative morbidity rate was 22%. The 5-year actuarial survival rate after repeat resection was 32%, with a median length of survival of 39.9 months. There were three patients who survived for > 5 years after repeat resection. Sixteen patients (70%) developed recurrent disease at a median interval of 11 months after the second resection; 10 of these 16 patients (62%) had new hepatic metastases. No clinical or pathological factors were significant in predicting long-term survival. CONCLUSIONS Repeat liver resection for recurrent colorectal metastases (a) can be performed safely with acceptable mortality and morbidity rates and (b) may result in long-term survival in some patients.

Abstract
OBJECTIVE The authors assess the long-term results of repeat hepatectomies for recurrent metastases of colorectal cancer and determine the factors that can predict survival. SUMMARY BACKGROUND DATA Safer techniques of hepatic resection have allowed surgeons to consider repeat hepatectomy for colorectal metastases in an increasing number of patients. However, higher operative bleeding and increased morbidity have been reported after repeat hepatectomies, and the long-term benefit of these procedures needs to be evaluated. STUDY POPULATION Sixty-four patients from a group of 243 patients resected for colorectal liver metastases were submitted to 83 repeat hepatectomies (64 second, 15 third, and 4 fourth hepatectomies). Combined extrahepatic surgery was performed in 21 (25%) of these 83 repeat hepatectomies. RESULTS There was no intraoperative or postoperative mortality. Operative bleeding was not significantly increased in repeat hepatectomies as compared to first resections. Morbidity and duration of hospital stay were comparable to first hepatectomies. Overall and disease-free survival after a second hepatectomy were 60% and 42%, respectively, at 3 years and 41% and 26%, respectively, at 5 years. Factors of prognostic value on univariate analysis included the curative nature of first and second hepatectomies (p = 0.04 and p = 0.002, respectively), an interval between the two procedures of more than 1 year (p = 0.003), the number of recurrent tumors (p = 0.002), serum carcinoembryonic antigen levels (p = 0.03), and the presence of extrahepatic disease (p = 0.03). Only the curative nature of the second hepatectomy and an interval of more than 1 year between the two procedures were independently related to survival on multivariate analysis. CONCLUSIONS Repeat hepatectomies can provide long-term survival rates similar to those of first hepatectomies, with no mortality and comparable morbidity. Combined extrahepatic surgery can be required to achieve tumor eradication. Repeat hepatectomies appear worthwhile when potentially curative.

Abstract
BACKGROUND This is a retrospective clinical study done to examine survival of patients undergoing repeat hepatic resection for recurrent colorectal hepatic metastases. METHODS The records of 131 patients undergoing hepatic resection for metastatic colorectal cancer were reviewed. Curative resection was performed in 107 of these patients. Thirty-one experienced recurrences confined to the liver. Thirteen (13 of 107, 12%) of them underwent resection and make up the study population. RESULTS The eight men (62%) and five women (38%) had a median age of 60 years (range, 32 to 75 years). In 30% of patients recurrence developed near the original resection site. In 70% the recurrences were remote from the original site. The patients underwent a total of six wedge resections, two left lateral segmentectomies, three right lobectomies, and two trisegmentectomies. Average blood loss was 2995 cc; average hospital stay was 17.2 days. Morbidity was 23% (3 of 13); mortality was 8% (1 of 13). Four patients died of recurrent disease, with a mean disease-free survival of 9.7 months (median, 7.5 months; range, 3 to 21 months) and mean total survival of 39 months (median, 24 months; range, 8 to 99 months). One of these patients had a second recurrence resected at month 21 and lived an additional 78 months. Seven patients were alive with no evidence of disease, with a mean follow-up time of 34.9 months (median, 14 months; range, 1 to 186 months). Actual 5-year survival was 23% (3 of 13). Actual disease-free 5-year survival was 15% (2 of 13). CONCLUSIONS In properly selected patients morbidity, mortality, and survival after repeat resection are similar to those after initial resection.

Abstract
Almost one-third of patients dying from colorectal cancer have tumor limited to the liver. Systemic chemotherapy is the appropriate palliative management of patients with metastases to the liver and other sites. For many patients with isolated hepatic metastases, systemic chemotherapy is also the most appropriate treatment. However, results with systemic chemotherapy indicate that one-third or less of patients will respond to such treatments, and long-term survival is rare. In this report we provide information concerning the natural history of colorectal hepatic metastases, followed by the expected benefits with systemic chemotherapy. This information provides background for the regional therapeutic strategies of surgical resection, cryosurgery, and hepatic artery chemotherapy. We discuss the selection factors appropriate for such treatments, morbidity and mortality, and the potential long-term benefits of such approaches. The last section focuses on surgical considerations in hepatic resection and hepatic artery chemotherapy.

Abstract
Patients with cancer recurrence limited to the liver alone after a first liver resection may be candidates for a repeat resection. Some 191 second and ten third liver resections for recurrent colorectal metastases, and 128 second and ten third liver resections for recurrent hepatocellular carcinoma (HCC), were evaluated after reviewing the literature. The 5-year survival rate after second liver resection for colorectal metastases was 26 per cent with a median survival time of 30 months. Mortality and morbidity rates were 1.2 and 27.4 per cent respectively. The 5-year survival rate after second resection for HCC was 40 per cent with a median survival time of 40 months. The operative mortality rate was 2.3 per cent; morbidity occurred in 13 per cent of patients with HCC. Survival after primary colorectal resection was significantly better for patients with metachronous metastases than for those with synchronous disease; survival correlated with a long interval between the first and second liver resection (in both colorectal liver cancer and HCC). Repeated liver resection may be performed in selected patients and yield a similar survival to that obtained after first liver resection.

Abstract
OBJECTIVE The authors addressed whether a repeat hepatic operation is warranted in patients with recurrent isolated hepatic metastases. Are the results as good after second operation as after first hepatic operation? SUMMARY BACKGROUND DATA Five-year survival after initial hepatic operation for colorectal metastases is approximately 33%. Because available alternative methods of treatment provide inferior results, hepatic resection for isolated colorectal metastasis currently is well accepted as the best treatment option. However, the main cause of death after liver resection for colorectal metastasis is tumor recurrence. METHODS Records of 95 patients undergoing initial hepatic operation and 10 patients undergoing repeat operation for isolated hepatic metastases were reviewed for operative morbidity and mortality, survival, disease-free survival, and pattern of failure. The literature on repeat hepatic resection for colorectal metastases was reviewed. RESULTS The mean interval between the initial colon operation and first hepatic resection was 14 months. The mean interval between the first and second hepatic operation was 17 months. Operative mortality was 0%. At a mean follow-up of 33 +/- 27 months, survival in these ten patients was 100% at 1 year and 88% +/- 12% at 2 years. Disease-free survival at 1 and 3 years was 60% +/- 16% and 45% +/- 17%, respectively. After second hepatic operation, recurrence has been identified in 60% of patients at a mean of 24 +/- 30 months (median 9 months). Two of these ten patients had a third hepatic resection. Survival and disease-free survival for the 10 patients compared favorably with the 95 patients who underwent initial hepatic resection. CONCLUSIONS Repeat hepatic operation for recurrent colorectal metastasis to the liver yields comparable results to first hepatic operations in terms of operative mortality and morbidity, survival, disease-free survival, and pattern of recurrence. This work helps to establish that repeat hepatic operation is the most successful form of treatment for isolated recurrent colorectal metastases.

Abstract
BACKGROUND Recurrence occurs in 65% to 85% of patients after initial hepatectomy for metastases from colorectal cancer. Approximately one half of these have liver metastases, and in 20% to 30% only the liver is involved. Opportunity for resection is frequently limited because of diffuse liver disease or extrahepatic extension, and only 10% to 25% of these patients have conditions amenable to resection. This current review is focused on the rationale, indications, and results of resection of hepatic metastases from colorectal cancer. METHODS The major series of liver resection were reviewed, and the cases of repeat resections were culled out. In addition to standard clinical parameters, the indications and timing after initial resection and the survival and subsequent recurrence after repeat resection were recorded. RESULTS A comprehensive review of the 28 series showed that the mean interval between the first and second liver varied from 9 to 33 months and was about 17.5 months in the two largest series. The median survival in series reporting 10 or more patients was 19 months (mean, 24 months), which is comparable to data in single resection series. In the large French Association series containing 1626 patients with single resections and 144 patients with two resections, the 5-year survival was 25% and 16%, respectively. The recurrence rate after repeat resection is high (greater than 60%), and one half are in the liver. The prognostic factors favoring repeat resection are variable, but they include absence of extrahepatic extension of tumor and a complete resection of the liver metastases. CONCLUSIONS Repeat hepatic liver resection for metastatic colorectal cancer in carefully selected patients appears warranted in view of reasonable survival expectations, which approach that of single liver resection. Risk of recurrence is high, however, suggesting the need for rigorous preoperative and intraoperative assessment and postoperative adjuvant therapy

Abstract
The initial enthusiasm for the development of diagnostic and therapeutic studies involving the use of monoclonal antibodies was replaced by scepticism as hopes remained unfulfilled. Against this background one needs to ask whether immunoscintigraphy (IS) serves clinical needs effectively and whether radioimmunotherapy (RIT) has a future. The current review considers these questions by reference to relevant studies. Taking colorectal cancer as an example, an appraisal is offered of the ability of IS to detect disease at an early stage and thereby to reduce mortality, and of the influence of the results of IS on patient management. It is concluded that in a limited number of cases of colorectal cancer and other solid tumors, IS will allow surgery to be performed at a stage where cure is still possible because of its ability to detect early recurrence. Turning to RIT, the results of studies in respect of various tumour types are reviewed, with due attention to reported toxicity. As regards colorectal cancer, no consistent therapeutic effects have been achieved, and myelotoxicity is typically the dose-limiting factor. Thus many questions remain to be answered, regarding antigens to be targeted, fractionation schedule, the use of "humanised" antibodies, choice of radionuclide and the use of intact immunoglobulins or fragments. These questions are considered. Overall it is concluded that the most promising application of RIT is as adjuvant therapy in patients with minimal residual disease, and a controlled multicentre trial is recommended. The development of more potent radio-immunoconjugates for therapeutic and ultimately diagnostic purposes will contribute to the improvement and development of IS by increasing its potential to influence prognosis.

Abstract
Current data indicate that liver resection is the only available treatment that regularly produces long-term survival with possible cure in patients with metastatic colorectal carcinoma to the liver. Although a number of clinical or pathologic factors predicts a poor outcome, the only absolute contraindications to liver resection are general health incompatible with recovery from major hepatic resection or clear evidence of wide dissemination of disease. Important areas for future study include the potential role of adjuvant regional chemotherapy after resection and cryoablation of "close" margins. For patients with unresectable disease, operative therapy also plays an important role. Multiple operative modalities hold promise in palliative treatment in the setting of clinically incurable disease. It is imperative that a large randomized trial of regional chemotherapy be performed allowing no crossover and with mortality as an endpoint. Additionally, the role of cryoablation begs systematic investigation to ensure proper use of this modality.

Abstract
OBJECTIVE The authors weighed the risks and benefits of repeat liver resections for colorectal metastatic disease. METHOD In the 6-year period between January 1985 and June 1991, 499 patients underwent liver resections for colorectal metastases at the Memorial Sloan-Kettering Cancer Center. Of these, 25 patients had repeat surgical resections for isolated recurrent disease to the liver. The clinical data for these patients were reviewed. RESULTS The median interval between the two resections was 11 months. There were no perioperative deaths, and the complication rate was 28%. Median follow-up after the second liver resection is 19 months, with median survival of 17 months for nonsurvivors. Although the median survival after the second resection is 30 months, 20 of the 25 patients have had recurrences with a median disease-free interval of only 9 months. No characteristic of primary or metastatic disease predicted outcome, including time between presentation of the primary and development of liver metastases, disease-free interval after the first liver resection, and bilobar liver involvement. CONCLUSIONS Although repeat liver resections can be performed safely and improves survival, the likelihood of cure from such resection therapy is low. This likelihood of further recurrences encourage studies of adjuvant or alternative treatments of this population.

Abstract
Hepatic resection is the only treatment for patients with colorectal cancer metastatic to the liver that has resulted in long-term survival. This apparent efficacy of hepatectomy has prompted efforts to expand the surgical approach for disease progression within the liver. A review of personal experience and of the literature was performed in an attempt to define the role of surgery for disease progression. Twenty-one patients who underwent hepatic resection between 1983 and 1991 for isolated disease progression in the liver were retrospectively reviewed. The median follow-up of patients still alive was 1.7 years (range 4 months to 4.5 years). The median survival from the date of repeat hepatic resection was 3.4 years with an estimated actuarial survival rate of 43 per cent at 4 years. These patients experienced no significant morbidity and the mortality rate was 5 per cent. Hepatic resection of metastatic colorectal carcinoma can produce long-term survival without prohibitive risk. These findings support an aggressive surgical approach for metastatic progression in the liver from colorectal carcinoma.

Abstract
OBJECTIVE The object of this study was to evaluate the prognostic significance of pre- and postoperative serum carcinoembryonic antigen (CEA) levels in the resectional treatment of colorectal hepatic metastases. The main question was whether postoperative CEA levels correlated with survival and the time to recurrence. SUMMARY BACKGROUND DATA Despite numerous investigations on prognostic factors in colorectal cancer, only sparse data are available to estimate the patient's individual risk for tumor recurrence postoperatively. It is controversial whether preoperative CEA values are of prognostic significance, and after observing the kinetics of CEA decline, elevated CEA levels postoperatively were found to be an ominous sign. CEA therefore could indicate the presence of a tumor burden after resection. METHODS One hundred sixty-six patients undergoing hepatic resection for colorectal metastases with curative intent were prospectively documented and underwent multivariate analysis for indicators of prognosis. RESULTS Abnormal preoperative CEA levels were not of prognostic significance compared with values within the normal range (survival, 36 vs. 30 months; p = 0.12; disease-free survival, 12 vs. 10 months; p = 0.82). The postoperative serum CEA level, however, was the most predictive factor with regard to survival and the disease-free interval. Patients in whom CEA levels were abnormal before surgery and returned into the normal range after resection had significantly better survival times (37 vs. 23 months, p = 0.0001) and disease-free survival times (12 vs. 6.2 months, p = 0.0001) compared with patients with persistently abnormal values. CONCLUSIONS Pre- and postoperative determination of the serum CEA level is mandatory to judge whether a curative resection has been performed and whether tumor has been left behind after the operation. Postoperative CEA levels also should be used as a stratification criterion in adjuvant treatment studies after hepatic resection to indicate patients with a high risk of tumor recurrence.

Abstract
Redo hepatic resection for recurrent colorectal metastasis was performed in eight patients. There was no operative mortality; major morbidity occurred in 25% and minor morbidity in 13% of patients. Four patients are alive and disease-free at 9, 23, 39, and 49 months, respectively, after their repeat hepatic resection. Four patients have died of recurrent disease, with a median time to recurrence of 6 months and median survival of 15 months. Patterns of failure include hepatic failure alone in two patients and pulmonary and hepatic failure in two. Repeat liver resection can be performed safely and may be beneficial in some patients with recurrent metastases confined to the liver after previous hepatic metastasectomy.
