Zhou JM, Wang L, Mao AR. Value and prognostic factors of repeat hepatectomy for recurrent colorectal liver metastasis. Hepatobiliary Pancreat Dis Int 2023; 22:570-576. [PMID: 36858891 DOI: 10.1016/j.hbpd.2023.02.005] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/03/2022] [Accepted: 02/10/2023] [Indexed: 03/03/2023]
Abstract
BACKGROUND More than 50% of patients with colorectal cancer develop liver metastases. Hepatectomy is the preferred treatment for resectable liver metastases. This review provides a perspective on the utility and relevant prognostic factors of repeat hepatectomy in recurrent colorectal liver metastasis (CRLM). DATA SOURCES The keywords "recurrent colorectal liver metastases", "recurrent hepatic metastases from colorectal cancer", "liver metastases of colorectal cancer", "repeat hepatectomy", "repeat hepatic resection", "second hepatic resection", and "prognostic factors" were used to retrieve articles published in the PubMed database up to August 2020. Additional articles were identified by a manual search of references from key articles. RESULTS Despite improvements in surgical methods and perioperative chemotherapy, recurrence remains common in 37%-68% of patients. Standards or guidelines for the treatment of recurrent liver metastases are lacking. Repeat hepatectomy appears to be the best option for patients with resectable metastases. The commonly reported prognostic factors after repeat hepatectomy were R0 resection, carcinoembryonic antigen level, the presence of extrahepatic disease, a short disease-free interval between initial and repeat hepatectomy, the number (> 1) and size (≥ 5 cm) of hepatic lesions, requiring blood transfusion, and no adjuvant chemotherapy after initial hepatectomy. The median overall survival after repeat hepatectomy ranged from 19.3 to 62 months, and the 5-year overall survival ranged from 21% to 73%. Chemotherapy can act as a test for the biological behavior of tumors with the goal of avoiding unnecessary surgery, and a multimodal approach involving aggressive chemotherapy and repeat hepatectomy might be the treatment of choice for patients with early recurrent CRLM. CONCLUSIONS Repeat hepatectomy is a relatively safe and effective treatment for resectable recurrent CRLM. The presence or absence of prognostic factors might facilitate patient selection to improve short- and long-term outcomes.

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: 9] [Impact Index Per Article: 3.0] [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.

Park CJ, Armenia SJ, Cowles RA. Trends in Routine and Complex Hepatobiliary Surgery Among General and Pediatric Surgical Residents: What is the Next Generation Learning and is it Enough? JOURNAL OF SURGICAL EDUCATION 2019; 76:1005-1014. [PMID: 30902561 DOI: 10.1016/j.jsurg.2019.02.007] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/30/2018] [Revised: 02/12/2019] [Accepted: 02/19/2019] [Indexed: 06/09/2023]
Abstract
OBJECTIVE Previous studies reveal a correlation between surgical volume and outcomes; thus, a similar relationship likely exists between trainee operative volume and technical competence. While routine hepatobiliary surgery is commonplace, trainee exposure to the more advanced procedures may be lacking. We hypothesize that experience in complex hepatobiliary procedures may be deficient both during general surgery residency and pediatric surgery fellowship training. DESIGN Case log data from the ACGME were queried for general surgery residents (2000-2017) and pediatric surgery fellows (2004-2017). Laparoscopic cholecystectomy was considered a routine hepatobiliary procedure for both specialties. For general surgery, hepatic lobectomy/segmentectomy and choledochoenteric anastomosis were considered complex and for pediatric surgery, hepatic lobectomy, biliary atresia and choledochal cyst procedures were considered complex. SETTING Publicly available case log data from the ACGME. PARTICIPANTS General surgery residents and pediatric surgery fellows at ACGME-accredited training programs. RESULTS The number of trainees increased over the study period for both groups. Mean case volumes for laparoscopic cholecystectomy increased by 36% in surgery graduates and by 114% in pediatric surgery graduates. In surgery, the mean volumes for choledochoenteric anastomosis procedures decreased by 53% from 3.0 to 1.4 procedures/year with increasing variability in trainee experience. Volumes for hepatic lobectomy/segmentectomy increased by 68% from 3.4 to 5.7 procedures/year with decreasing variability. In pediatric surgery, case volumes for complex procedures were low (mean <4/year), highly variable among trainees, and appear unchanged between 2004 and 2017. In every year analyzed, at least 1 pediatric surgery trainee reported doing 0 cases in one of these complex categories. CONCLUSIONS Case logs suggest that the volume of complex hepatobiliary surgery remains low and highly variable in both disciplines with some trainees obtaining minimal or no exposure to certain cases. The relationship between these trends and the development of competency is worthy of further study.

Abstract
BACKGROUND The feasibility of the liver-first approach for synchronous colorectal liver metastases (CRLM) has been established. We sought to assess the short-term and long-term outcomes for these patients. METHODS Outcomes of patients who underwent a liver-first approach for CRLM between 2005 and 2015 were retrospectively evaluated from a prospective database. RESULTS Of the 92 patients planned to undergo the liver-first strategy, the paradigm could be completed in 76.1%. Patients with concurrent extrahepatic disease failed significantly more often in completing the protocol (67% versus 21%; p = 0.03). Postoperative morbidity and mortality were 31.5% and 3.3% following liver resection and 30.9% and 0% after colorectal surgery. Of the 70 patients in whom the paradigm was completed, 36 patients (51.4%) developed recurrent disease after a median interval of 20.9 months. The median overall survival on an intention-to-treat basis was 33.1 months (3- and 5-year overall survival: 48.5% and 33.1%). Patients who were not able to complete their therapeutic paradigm had a significantly worse overall outcome (p = 0.03). CONCLUSION The liver-first approach is feasible with acceptable perioperative morbidity and mortality rates. Despite the considerable overall-survival-benefit, recurrence rates remain high. Future research should focus on providing selection tools to enable the optimal treatment sequence for each patient with synchronous 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
SATB2 (Special AT-rich sequence-binding protein 2) has recently been shown to be a specific biomarker of colorectal cancer (CRC). The aim of this study was to investigate the diagnostic potential of SATB2 as a means of detecting a CRC origin for liver metastases. SATB2 expression was examined in a resection cohort of 101 CRC and 273 non-CRC adenocarcinoma samples using immunohistochemistry (IHC). The diagnostic accuracy of CRC origins of liver metastases based on SATB2 and a three marker panel of SATB2, CK20 and CDX2 was evaluated using an independent cohort of 192 liver biopsies. IHC showed 97 of the 101 (96.0%) primary CRC samples were SATB2 positive, compared to only 6 of the 273 (2.1%) samples of other cancer types. The sensitivity, specificity and AUC values of SATB2 expression in resection samples were 97%, 97.1% and 0.977, respectively. Meanwhile, for the liver biopsy samples, the sensitivity, specificity and AUC values of a CRC liver metastases was 92.2%, 97.8% and 0.948 for SATB2, 95.1%, 91.0% and 0.959 for CK20, and 100%, 85.4% and 0.976 for CDX2, respectively. Further analysis demonstrated that all three-marker positivity was detected in 92/103 (89.3%) CRC and 2/89 (2.2%) non-CRC liver metastases sampled by biopsy. Our findings suggest that SATB2, as measured by IHC, could serve as a promising diagnostic biomarker of CRC metastases. Combining evaluation of SATB2 with CK20 and CDX2 to form a three marker panel further improved the detection of metastatic CRCs in liver biopsy tissues.

Oncotarget 2017; 8:102531-102539. [PMID: 29254268 PMCID: PMC5731978 DOI: 10.18632/oncotarget.20934] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/08/2017] [Accepted: 08/28/2017] [Indexed: 12/11/2022] Open
Abstract
The aims of this study were to assess early recurrence predictive factors and elucidate the best early recurrence management. 255 patients with colorectal liver metastases (CRLM) who underwent hepatectomy were retrospectively analyzed. A total of 87 patients (34.1%) developed early recurrence, defined as recurrence that occurred within 6 months after resection. Multivariate analysis showed that preoperative carcino-embryonic antigen (CEA) level ≥ 30 ng/ml, primary tumor lymphovascular invasion (LVI), number of metastases ≥ 4, R1 resection and initially unresectable disease were independent predictors of early recurrence. A predictive scoring system for early recurrence was created by incorporating these factors, and this system showed good discrimination (concordance index of 0.78). In early recurrent patients who underwent salvage treatment, those with 0-2 risk factors demonstrated a significantly longer median survival after recurrence than patients with 3-5 risk factors (33.4 months vs. 20.2 months, p = 0.001). For patients who underwent chemotherapy alone, the median survival after recurrence between two groups was comparable (18.3 months vs. 22.6 months, p = 0.926). Multivariate analysis revealed that primary tumor lymph node metastases (HR = 1.96, p = 0.032), early recurrence (HR = 1.67, p = 0.045), salvage treatment for recurrence (HR = 0.47, p = 0.002) and predictive scores for early recurrence (HR = 1.39, p = 0.004) were independent factors for survival in patients with recurrence. In patients with early recurrence, bilobar distribution of metastases (HR = 2.05, p = 0.025) and salvage treatment for recurrence (HR = 0.46, p = 0.019) were independent factors for survival. In conclusion, we developed a predictive model that is a very useful tool for determining both the likelihood of early recurrence and the necessity for salvage treatment.

Abstract
PURPOSE Recent studies have reported that margins alone do not predict survival in patients with a positive chemotherapy response. The aim of this retrospective study is to analyze the surgical and oncological outcomes of patients who underwent chemotherapy and liver resection for colorectal liver metastases (CRLM) with lesions detached from the main hepatic veins, comparing the vein-preserving (VP) approach with traditional surgery. METHODS Fourteen patients undergoing VP surgery from January 2006 to January 2013 were matched in a 1:2 ratio with a control group (CG) of 28 patients undergoing traditional resection. RESULTS The median follow-up was 43 months. The radiological response was classified as 'partial response' in eight VP patients and 11 controls (57 vs. 39 %, p = 0.249) and as 'stable disease' in three VP patients and 9 controls (21 vs. 32 %, p = 0.465). Ten VP (71.4 %) and twenty CG patients (71.4 %) experienced tumor relapse (p = 0.99). No venous edge recurrences were recorded in the VP group, whereas 1/13 (7.7 %) was observed in the control group (p = 0.99). The pathological response rate was 64 vs. 39 % (p = 0.037) in VP and CG patients, respectively. The 5-year recurrence-free survival rate was 24 % for VP patients and 25 % for CG patients (p = 0.431). CONCLUSION In patients with a positive CT response, CRLM can be detached from the hepatic veins, as the oncological outcome is similar to that of a larger resection. The VP approach offers the possibility to enlarge the surgical indications, thus optimizing future surgical treatment chances.

Abstract
BACKGROUND Although several studies have reported the outcomes of surgery for the treatment of liver metastases of gastric cancer (GLM), indications for liver resection for gastric metastases remain controversial. This study was designed to identify prognostic determinants that identify operable hepatic metastases from gastric cancer and to evaluate the actual targets of surgical therapy. METHODS Retrospective analysis was performed on outcomes for 24 consecutive patients at five institutions who underwent gastrectomy for gastric cancer followed by curative hepatectomy for GLM between 2000 and June 2012. RESULTS Overall 5-year survival and median survival were 40.1 % and 22.3 months, respectively. Uni- and multivariate analyses showed that liver metastatic tumour size less than 5 cm was the most important predictor of overall survival (OS, p = 0.03). Four patients survived >5 years. Repeat hepatectomy was performed in three patients. Two of these patients have remained disease-free since the repeat hepatectomy. CONCLUSIONS GLM patients with metastatic tumour diameter less than 5 cm maximum are the best candidates for hepatectomy. Hepatic resection should be considered as an option for gastric cancer patients with liver metastases.

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.

Abstract
PURPOSE Patients with recurrence after complete resection of colorectal liver metastases (CLM) are considered for repeat resection as a potential salvage therapy (PST). However, outcomes for this approach are not well defined. We sought to analyze the natural history of recurrence and PST in a large cohort of patients with long-term follow-up. METHODS Recurrence patterns, treatments, and outcomes in consecutive patients undergoing resection for colorectal liver metastases were analyzed retrospectively. PST was defined as repeat resection of all recurrent disease and effective salvage therapy (EST) as free of disease for 36 months after last PST. Factors associated with PST, EST, and outcomes were analyzed. RESULTS Of 952 patients who underwent resection, 594 (62 %) experienced recurrence (median interval = 13 months). Initial recurrences involved liver (n = 157,26 %), lung (n = 167,28 %), multiple sites (n = 171,29 %), and other single sites (n = 99,17 %). PST was performed in 160 (27 %) of 594, most commonly with a single site of recurrence (n = 149). Young age (p = 0.01), negative initial resection margin (p = 0.003), initial tumor size <5 cm (p = 0.006), and recurrence pattern (p < 0.001) were independently associated with PST. Thirty-six patients experienced EST (25 % of PSTs). Overall median survival was 61 and 43 months in those with recurrence. Median survival of patients undergoing PST was 87 months compared to 34 months for those who did not. CONCLUSIONS Recurrence is common after CLM resection, but 27 % of patients were able to undergo PST. Approximately one-quarter of these experienced EST and may be cured. PST is associated with long-term survival and possible cure, and therefore active surveillance after CLM resection is justified.

Abstract
The outcomes and management of colorectal liver metastasis have undergone many changes. The incidence of recurrence after liver resection for hepatic metastasis remains very high. Liver resection, which provides the only curative treatment, is believed to have improved the long-term outcome of these patients. However, the management and outcomes of patients with colorectal liver metastasis have greatly improved in the last decade, suggesting that the current use of aggressive multimodality treatments, including surgical resection combined with modern chemotherapeutic regimens, effectively prolong the life expectancy of these patients.

Abstract
BACKGROUND Opinions on the suitability of repeat hepatectomy for patients with recurrent colorectal liver metastases (CRLMs) vary among studies. We conducted a meta-analysis to establish the criteria for selecting the best candidates for a second hepatectomy. METHODS Database and manual searches were performed to identify comparative or prognostic studies published up to October 2013. Outcomes of interest included disease characteristics, perioperative outcomes, and long-term survival after initial and second hepatectomies for patients with CRLM. Study quality was appraised using the Newcastle-Ottawa scale and a modified Hayden's score. RESULTS A total of 7226 patients from 27 studies were included. Recurrent CRLMs after initial hepatectomy were more likely to be solitary (RR = 0.86, P = 0.045), unilobar (RR = 0.60, P < 0.001), and smaller (WMD = -0.66, P < 0.001). Postoperative morbidity and mortality were comparable between initial and second hepatectomies (RR = 1.10, P = 0.191; RR = 0.78, P = 0.678, respectively). In high-quality studies, patients showed better survival after a second hepatectomy than those after a single hepatectomy (HR = 0.68, P = 0.022). Patients meeting the following six predictors survived longer after second hepatectomy: disease-free survival after initial hepatectomy >1 y (P = 0.034); solitary CRLM at second hepatectomy (P < 0.001); unilobar CRLM at second hepatectomy (P = 0.009); maximal size of CRLM at second hepatectomy ≤ 5 cm (P = 0.035); lack of extrahepatic metastases at second hepatectomy (P < 0.001); and R0 resection at second hepatectomy (P < 0.001). CONCLUSIONS Second hepatectomy is a safe and feasible procedure for patients with recurrent CRLM. In fact, in well-selected patients it improves overall survival. The established criteria can help clinicians to select the best candidates for second hepatectomy and to achieve better long-term outcomes after resection.

Aggressive treatment of patients with metastatic colorectal cancer increases survival: a scandinavian single-center experience. HPB SURGERY : A WORLD JOURNAL OF HEPATIC, PANCREATIC AND BILIARY SURGERY 2013; 2013:727095. [PMID: 23840074 PMCID: PMC3690245 DOI: 10.1155/2013/727095] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/20/2013] [Revised: 04/22/2013] [Accepted: 05/20/2013] [Indexed: 12/21/2022]
Abstract
Background. We examined overall and disease-free survivals in a cohort of patients subjected to resection of liver metastasis from colorectal cancer (CRLM) in a 10-year period when new treatment strategies were implemented. Methods. Data from 239 consecutive patients selected for liver resection of CRLM during the period from 2002 to 2011 at a single center were used to estimate overall and disease-free survival. The results were assessed against new treatment strategies and established risk factors. Results. The 5-year cumulative overall and disease-free survivals were 46 and 24%. The overall survival was the same after reresection, independently of the number of prior resections and irrespectively of the location of the recurrent disease. The time intervals between each recurrence were similar (11 ± 1 months). Patients with high tumor load given neoadjuvant chemotherapy had comparable survival to those with less extensive disease without neoadjuvant chemotherapy. Positive resection margin or resectable extrahepatic disease did not affect overall survival. Conclusion. Our data support that one still, and perhaps to an even greater extent, should seek an aggressive therapeutic strategy to achieve resectable status for recurrent hepatic and extrahepatic metastases. The data should be viewed in the context of recent advances in the understanding of cancer biology and the metastatic process.

Abstract
BACKGROUND The oncological benefit of repeat hepatectomy for patients with recurrent colorectal metastases is not yet proven. This study assessed the value of repeat hepatectomy for these patients within current multidisciplinary treatment. METHODS Consecutive patients treated by repeat hepatectomy for colorectal metastases between January 1990 and January 2010 were included. Patients undergoing two-stage hepatectomy were excluded. Postoperative outcome was analysed and compared with that of patients who had only a single hepatectomy. RESULTS A total of 1036 patients underwent 1454 hepatectomies for colorectal metastases. Of these, 288 patients had 362 repeat hepatectomies for recurrent metastases. Some 225 patients (78·1 per cent) had two hepatectomies, 52 (18·1 per cent) had three hepatectomies, and 11 patients (3·8 per cent) had a fourth hepatectomy. Postoperative morbidity following repeat hepatectomy was similar to that after initial liver resection (27·1 per cent after first, 34·4 per cent after second and 33·3 per cent after third hepatectomy) (P = 0·069). The postoperative mortality rate was 3·1 per cent after repeat hepatectomy versus 1·6 per cent after first hepatectomy. Three- and 5-year overall survival rates following first hepatectomy in patients who underwent repeat hepatectomy were 76 and 54 per cent respectively, compared with 58 and 45 per cent in patients who had only one hepatectomy (P = 0·003). In multivariable analysis, repeat hepatectomy performed between 2000 and 2010 was the sole independent factor associated with longer overall survival. CONCLUSION Repeat hepatectomy for recurrent colorectal metastases offers long-term survival in selected patients.

Abstract
Introduction. Simultaneous resection of primary colorectal carcinoma (CRC) and synchronous liver metastases (SLMs) is subject of debate with respect to morbidity in comparison to staged resection. The aim of this study was to evaluate our initial experience with this approach. Methods. Five patients with primary CRC and a clinical diagnosis of SLM underwent combined laparoscopic colorectal and liver surgery. Patient and tumor characteristics, operative variables, and postoperative outcomes were evaluated retrospectively. Results. The primary tumor was located in the colon in two patients and in the rectum in three patients. The SLM was solitary in four patients and multiple in the remaining patient. Surgical approach was total laparoscopic (2 patients) or hand-assisted laparoscopic (3 patients). The midline umbilical or transverse suprapubic incision created for the hand port and/or extraction of the specimen varied between 5 and 10 cm. Median operation time was 303 (range 151-384) minutes with a total blood loss of 700 (range 200-850) mL. Postoperative hospital stay was 5, 5, 9, 14, and 30 days. An R0 resection was achieved in all patients. Conclusions. From this initial single-center experience, simultaneous laparoscopic colorectal and liver resection appears to be feasible in selected patients with CRC and SLM, with satisfying short-term results.

Abstract
BACKGROUND Although hepatectomy for metastatic colorectal cancer (mCRC) offers prolonged survival in up to 40% of people, recurrence rates are high, approaching 70%. Many patients experience recurrent disease in the liver after initial hepatectomy. We examined our experience with repeat hepatectomy for mCRC. METHODS After Institutional Review Board approval, we reviewed the records of all patients at a single institution who underwent hepatectomy for mCRC. Repeat hepatectomy was defined as partial liver resection any time after the initial hepatectomy for recurrent mCRC. We estimated time to recurrence and survival by using the Kaplan-Meier method and compared outcomes between groups by using the log-rank test. RESULTS From 1998 to 2008, 405 patients underwent hepatectomy for mCRC, and 215 (53%) experienced disease recurrence at a median of 13 months. Of 150 patients with liver-only or liver-predominant recurrence, 52 (35%) underwent repeat hepatectomy. The median time to recurrence after repeat hepatectomy was 10 months, and median overall survival was 19 months. There was one (1.9%) perioperative death, and there were 14 (27%) major complications. The median overall survival in the repeat hepatectomy group from the time of recurrence after initial hepatectomy was 22 months, compared with 15 months in the 98 patients with liver recurrence who were not selected for repeat hepatectomy (P=0.02). CONCLUSIONS Repeat hepatectomy for mCRC is feasible in highly selected patients, with acceptable perioperative morbidity and mortality. Although repeat hepatectomy should be considered, recurrence rates are high. Although the initial hepatectomy for mCRC is potentially curative, recurrence of metastatic disease in the liver is unlikely to be cured.

Abstract
BACKGROUND The outcome after a repeat hepatectomy for recurrent colorectal liver metastases (CLM) is not well defined. The present study examined the morbidity, mortality and long-term survivals after a repeat hepatectomy for recurrent CLM. METHODS Data on patients who underwent surgery for recurrent CLM between 1993 and 2009 were retrospectively evaluated. Patients who underwent radiofrequency ablation at the time of first treatment or at recurrence of CLM were excluded. RESULTS Forty-three patients underwent a repeat hepatectomy for recurrent CLM. At the time of recurrence, patients had a median of 1 (1-3) lesions and the median tumour size was 2 (0.5-8.7) cm. The post-operative morbidity and mortality rates were 12% and 0%, respectively. After a median follow-up of 33 months from a repeat hepatectomy, 5-year overall and progression-free survival rates were 73% and 22%, respectively. Using multivariate analysis, the largest initial CLM ≥5 cm and positive surgical margins at initial resection were independently associated with a worse survival after surgery for recurrent CLM. Positive surgical margins at repeat hepatectomy were a predictive factor for an increased risk of further recurrence. DISCUSSION A repeat hepatectomy for recurrent CLM was associated with excellent survival, low morbidity and no mortality. Surgeon-controlled variables, including margin-negative resection at first and repeat hepatectomy, contribute to good oncological outcome.

Abstract
BACKGROUND Lung metastases are considered a poor prognostic factor in patients with resectable colorectal liver metastases. STUDY DESIGN We reviewed records of 1,260 consecutive patients with liver-only or liver-plus-lung (L+L) metastases from colorectal cancer who underwent resection with curative intent (1995 to 2009). Survival and prognostic factors were analyzed. RESULTS There were 112 patients who underwent resection of L+L (mean 2 liver, 2 lung metastases). Mean tumor sizes were 3 cm and 1 cm, respectively. Thirty-four (31%) had bilateral lung metastases. Ten (9%) had synchronous L+L metastases, 60 (54%) had diagnosis of lung metastases within 1 year of liver resection. Most (108 of 112, 96%) had resection of liver before or at the same time as lung. Preoperative chemotherapy was used in 77 (69%) before liver resection and 56 (50%) before lung resection. Among L+L patients, no postoperative deaths occurred; postoperative morbidity rates were 26% after liver resection and 4% after lung resection. After a median of 49 months follow-up, L+L patients (n = 112) had better survival than liver only (n = 1,148) (5-year overall survival, L+L, 50% vs liver only, 40%; p = 0.01). CEA level > 5 ng/dL (hazard ratio [HR] 2.1, 95% CI 1.1 to 4.4, p = 0.04) and rectal primary (HR 2.9, 95% CI 1.4 to 6, p = 0.004) were associated with worse survival in L+L patients. CONCLUSIONS The survival rate for patients who undergo resection of L+L metastases from colorectal cancer is greater than the survival rate of the general population of patients who undergo resection of liver metastases only. The presence of resectable lung metastases is neither a poor prognostic factor nor a contraindication to resection of liver metastases.

Abstract
BACKGROUND The results of surgery for recurrent colorectal liver metastases (CLM) after radiofrequency ablation (RFA) have not been evaluated. METHODS From 1993 to 2009, data on patients who underwent resection or RFA for recurrent CLM were collected prospectively. Inclusion criteria for this study were RFA as initial treatment for CLM and resection of recurrent CLM after RFA. Postoperative results and oncological outcomes were analysed. RESULTS Twenty-eight patients (median number of tumours 1 (1-3), median size 2·8 (2·0-4·0) cm) met the inclusion criteria. Of these, 22 had recurrence at the site of RFA only, two developed new lesions, whereas four had both recurrent and de novo metastases. At the time of resection, patients had a median of 1 (1-13) CLM with a median maximum tumour diameter of 5·0 (1·8-11·0) cm, significantly larger than at the time of RFA (P = 0·021). Ninety-day postoperative morbidity and mortality rates were 46 per cent (13 of 28) and 7 per cent (2 of 28) respectively. After a median follow-up of 35 (0-70) months, 3-year overall and disease-free survival rates calculated by Kaplan-Meier analysis were 60 and 29 per cent respectively. Plasma carcinoembryonic antigen level over 5 ng/ml at the time of resection and a rectal primary tumour were associated with worse survival (P = 0·041 and P = 0·021 respectively). CONCLUSION Resection for recurrence after RFA is associated with significant morbidity and modest long-term benefit.

Abstract
BACKGROUND The impact of computed tomography (CT)-based follow-up for the detection of resectable disease recurrence following surgery for colorectal liver metastases (CRLM) was evaluated. METHODS Some 705 patients undergoing resection of CRLM between January 1993 and March 2007 were included. Surveillance comprised 3-monthly CT (thorax, abdomen and pelvis) in the first 2 years after surgery, 6 monthly for 3 years and annually from years 6 to 10. Survival differences following recurrence between patients managed surgically and palliatively were determined, and the cost was calculated. RESULTS Five-year disease-free and overall survival rates were 28.3 and 32.3 per cent respectively. Of 402 patients who developed recurrence within 2 years, 88 were treated with liver resection alone and 36 with lung and/or liver resection. Their 5-year overall survival rates were 31 and 30 per cent respectively, compared with 3.9 per cent in 278 patients managed palliatively (P < 0.001). For each 3-month interval during the first year of follow-up, patients with recurrence treated surgically had better overall survival than those treated palliatively. The cost of surveillance that identified 124 patients amenable to further resection was 12,338 pounds per operated recurrence. Assuming that patients with recurrence gained 5 years' survival, the mean survival gain was 4.28 years per resection and the cost per life-year gained was 2883 pounds. CONCLUSION Intensive 3-monthly CT surveillance after liver resection for CRLM detects recurrence that is amenable to further resection in a considerable number of patients. These patients have significantly better survival with a reasonable cost per life-year gained.

Abstract
OBJECTIVES Over the last decade, various groups have proposed prognostic scoring systems for patients with colorectal liver metastasis (CLM) treated with hepatic resection. The aims of the current study were to evaluate the differences between and clinical importance of these prognostic scoring systems and to determine their clinical applicability. METHODS Relevant articles were reviewed from the published literature using the MEDLINE database. The search was performed using the keywords 'colorectal cancer', 'metastases', 'liver resection' and 'hepatectomy'. RESULTS Twelve prognostic scoring systems were identified from 1996 to 2009. Six of these originated from European institutions, three from Asian and three from North American centres. The median study sample was 288 patients (range 81-1568 patients) and median follow-up was 35 months (range 16-52 months). All studies were retrospective in nature and the numbers of groups proposed by the various scoring systems ranged from three to six. All the studies used the Cox proportional hazard model for multi-variable analysis. CONCLUSIONS There is no 'ideal' prognostic scoring system for the clinical management of patients with CLM for hepatic resection. These prognostic scoring systems are clinically relevant with respect to survival but have not been used for risk stratification in controversial areas such as the administration of chemotherapy or surveillance programmes.

Abstract
INTRODUCTION Although 5-year survival approaches 55% following resection of colorectal liver metastasis, most patients develop recurrent disease that is often isolated to the liver. Although repeat curative intent surgery (CIS) is increasingly performed for recurrent colorectal liver metastasis, only small series have been reported. We sought to determine safety and efficacy of repeat CIS for recurrent colorectal liver metastasis as well as determine factors predictive of survival in a large multicenter cohort of patients. METHODS Between 1982 and 2008, 1,706 patients who underwent CIS--defined as curative intent hepatic resection/radiofrequency ablation (RFA)--for colorectal liver metastasis were identified from an international multi-institutional database. Two hundred forty-six (14.4%) patients underwent 301 repeat CIS. Data on clinico-pathologic factors, morbidity, and mortality were collected and analyzed. RESULTS Following initial CIS, 645 (37.8%) patients had recurrence within the liver. Of these, 246 patients underwent repeat CIS for recurrent disease. The majority had hepatic resection alone as initial therapy (n = 219; 89.0%). A subset of patients underwent third (n = 46) or fourth (n = 9) repeat CIS. Mean interval between surgeries was similar (first --> second, 19.1 months; second --> third, 21.5 months; third --> fourth, 11.3 months; P = 0.20). Extent of hepatic resection decreased with subsequent CIS (>or=hemihepatectomy: first CIS, 30.9% versus second CIS, 21.1% versus third/fourth CIS, 16.4%; P = 0.004). RFA was utilized in one quarter of patients undergoing repeat CIS (second CIS, 21.1% versus third/fourth CIS, 25.5%). Mortality and morbidity were similar following second, third, and fourth CIS, respectively (all P > 0.05). Five-year survival was 47.1%, 32.6%, and 23.8% following the first, second, and third CIS, respectively. Presence of extra-hepatic disease was predictive of worse survival (HR = 2.26, P = 0.01). CONCLUSION Repeat CIS for recurrent colorectal liver metastasis can be performed with low morbidity and near-zero mortality. Patients with no extra-hepatic disease are best candidates for repeat CIS. In these patients, repeat CIS can offer the chance of long-term survival.

Abstract
We have investigated a rapidly reversible hydrophobization of therapeutic agents for improving first-pass uptake in locoregional drug therapy. This approach involves the attachment of a hydrophobic moiety to the drug by highly labile chemical linkages that rapidly hydrolyze upon injection. Hydrophobization drastically enhances cell-membrane association of the prodrug and, consequently, drug uptake, while the rapid lability protects nontargeted tissues from exposure to the highly active agent. Using the membrane-impermeable DNA intercalator propidium iodide, and melphalan, we report results from in vitro cellular internalization and toxicity studies. Additionally, we report in vivo results after a single liver arterial bolus injection, demonstrating both tumor targeting and increased survival in a mouse tumor model.

Abstract
AIM Our aim was to determine independent predictors of survival after second liver resection and to confirm whether the type of first resection influences survival after repeat resection. METHODS Fifty-four patients who underwent a second liver resection for colorectal liver metastases were analyzed. To find independent predictors of survival, possible prognostic factors regarding the primary tumor, and the first and second resections were used in the Cox regression analysis. RESULTS There were three postoperative deaths within 90 days of surgery. The 3- and 5-year overall survival rates were 53% and 46%, respectively. The size of the tumor (>50mm) (p=0.005), serum carcinoembryonic antigen level (>30microg/L) (p=0.002), and the presence of a positive surgical margin at the second resection (p=0.006) were independent predictors of poor survival following the second resection. The type of first resection was not associated with survival but was associated with the ability to achieve a histological negative surgical margin at the second liver resection (p=0.01). CONCLUSION Three independent predictors of survival were identified. Major initial liver resection was associated with a reduced ability to achieve surgical clearance at the second resection. For colorectal liver metastases, major resection should only be performed if a negative margin cannot be achieved by minor resection.

Abstract
BACKGROUND We critically appraised the quantity and quality of current clinical evidence to demonstrate the efficacy and safety of repeat hepatectomy for recurrent colorectal liver metastases (CRLM). METHODS Electronic searches for relevant studies published in peer-reviewed medical journals on repeat hepatectomy for recurrent CRLM before January 2007 were performed on six databases. The quality of each included study was independently assessed. Clinical effectiveness was synthesized through a narrative review with full tabulation of results of all included studies. RESULTS Seventeen studies with more than 20 patients were included for quality appraisal and data extraction. All 17 included articles were observational cases series. The overall perioperative morbidity rate ranged from 7% to 30% and mortality rate varied from 0% to 5%. The overall median survival since the repeat hepatectomy ranged from 23 to 56 months, with 3- and 5-year survival of 24% to 68% and 21% to 49%, respectively. The median disease-free survival ranged from 9 to 52 months, with 3- and 5-year disease-free survival of 16% to 68% and 16% to 48%, respectively. CONCLUSIONS The current literature suggests that repeat hepatectomy is associated with a prolonged survival for recurrent CRLM and is justified in selected patients because there is a lack of evidence for effective alternative treatments.

Abstract
BACKGROUND The perioperative risk and long-term survival benefit of repeat hepatectomy for patients with liver metastases from colorectal cancer, compared with that of a first liver resection, has been reported with varying results in the literature. METHODS The literature was searched using Medline, Embase, Ovid, and Cochrane databases for all studies published from 1992 to 2006. Two authors independently extracted data using the following outcomes: postoperative complications and mortality; disease recurrence; and long-term survival. Trials were assessed using the modified Newcastle-Ottawa Score. Random-effect meta-analytical techniques were used for analysis. RESULTS Twenty-one studies met the inclusion criteria, comprising 3,741 patients. The use of adjuvant chemotherapy was similar in both groups (odds ratio [OR] = 0.97; 95% confidence interval [CI] = 0.54, 1.74; P = .92), as was the number of hepatic nodules present at the time of first or second resection (weighted mean difference [WMD] = 0.18; 95% CI = -0.22, 0.57; P = .380). Wedge resection was carried out less often at first hepatectomy (39% vs 46%; OR = 0.66; 95% CI = 0.44, 1.00; P = .05). There was significantly less blood loss in patients undergoing first versus second hepatectomy (WMD = 238 ml; 95% CI = 90, 385; P = .002). There was no difference in perioperative morbidity (OR = 1.01; 95% CI = 0.65, 1.55; P = .98), mortality (OR = 1.01; 95% CI = 0.18, 5.72; P = .99) or long-term survival (HR = 0.90; 95% CI = .66, 1.24; P = .530) between groups. CONCLUSIONS Repeat hepatectomy for patients with colorectal cancer metastases is safe and provides survival benefit equal to that of a first liver resection.

Abstract
Colorectal cancer is a major cause of cancer death in Western Europe and United States; the liver is the most common site for colorectal metastases. PET has an important role in the management of patients with colorectal liver metastases. It is an effective tool to detect hepatic metastases and to monitor the response to systemic and local therapy. The major impact of PET-CT over PET alone is the improvement in the certainty of lesion location. PET-CT has the unique advantage to combine functional and anatomic imaging in an integrated scanner; it allows a thoroughly evaluation of patients with colorectal liver metastases.

Abstract
BACKGROUND The selection of resective therapy for colorectal hepatic metastases remains controversial. The aim of this study is to investigate the prognostic factors for patients with resected liver metastases from colorectal cancer by analyzing not only clinicopathological factors but also recent immunohistological markers. METHODS Eighty-five patients underwent hepatic resection for metastatic colorectal cancer over the past 20 years. Fas/CD95 expression, microvessel density, and proliferating cell nuclear antigen (PCNA) proliferative activity were assessed with immunohistochemical methods in addition to the clinicopathological factors. Survival analysis was performed using the Kaplan-Meier method and Cox proportional hazards model, both univariately and multivariately. RESULTS Univariate and multivariate analyses revealed that the number of metastases, Fas/CD95 expression, and postoperative carcinoembryonic antigen doubling time (CEADT) were significant prognostic indicators, whereas the mode of hepatic resection, chemotherapy, and other clinicopathological factors had no influence on survival. Fas/CD95 index correlated with postoperative CEADT (p=0.039), number of metastases (p=0.018), and survival (p=0.023). CONCLUSIONS Our study confirmed the number of metastases and CEADT as prominent prognostic factors after hepatic resection for metastatic colorectal cancer. These two factors reflect the degree of Fas/CD95 signaling rather than angiogenesis or cancer growth rate.

Abstract
Abstract
Background
In some patients undergoing right hepatic trisectionectomy for metastases, extension of the resection beyond the falciform ligament is necessary to achieve tumour clearance. The aim of the present study was to assess the early and long-term outcomes and hepatic function in patients who underwent extensive liver resection beyond right trisectionectomy.
Methods
Thirty-eight patients who had extension of a right trisectionectomy, either in contiguity (IC) or in a non-anatomical (NA) fashion, for liver metastases were included in the study. In-hospital mortality, hepatic function and other morbidity were recorded. Survival outcomes were analysed for the subgroup of patients with colorectal liver metastases. The clinical risk score described by the Memorial Sloan–Kettering Cancer Center was applied to all patients with colorectal liver metastases.
Results
Sixteen patients had IC resection, 15 NA resection, and seven had both IC and NA procedures. There was one in-hospital death. Hepatic dysfunction was seen in 25 patients and two developed liver failure. Disease-free actuarial 3-year survival was 42 per cent for patients with colorectal liver metastases. Survival was significantly better in patients with a clinical risk score of 3 or less.
Conclusion
Extension of right trisectionectomy for liver metastases was associated with a low risk of death and hepatic failure.

Abstract
INTRODUCTION This study assesses the accuracy of routine whole body fluorodeoxyglucose-positron emission tomography (FDG-PET) in the pre-operative staging of patients with colorectal liver metastases (CLM). METHODS A prospective study of patients referred for hepatic resection was undertaken. Patients were staged by spiral CT and FDG-PET. The results of these investigations were considered independently. RESULTS Twenty-eight patients had confirmed CLM. Eleven patients had solitary CLM; 10 of whom were correctly identified by both modalities. In the remaining 17 patients, 10 had multiple CLM and seven had extrahepatic disease. FDG-PET detected all lesions (sensitivity 100%, specificity 91%). CT incorrectly diagnosed solitary CLM in five patients and failed to detect extrahepatic disease in four patients (sensitivity 47%, specificity 91%). FDG-PET resulted in altered management for 12 patients of whom seven avoided inappropriate surgery. CONCLUSION FDG-PET is more sensitive and specific for pre-operative staging of CLM. FDG-PET confers clinical benefit through altered patient management.

Abstract
BACKGROUND Indications for hepatectomy in patients with 4 or more hepatic colorectal metastases remain controversial. METHODS A retrospective cohort study was performed with data from 131 patients who underwent a total of 198 hepatectomies. Patients were grouped according to the number of metastases at the initial hepatectomy (analysis 1) or by the total number of metastases removed by multiple hepatectomies (analysis 2). RESULTS In analysis 1, the risk ratios for death of patients with 4 to 9 and 10 nodules to those with 1 to 3 nodules were 2.12 (95% CI, 0.99-4.23) and 7.32 (95% CI, 2.82-16.9), respectively. In analysis 2, the risk ratios for death were 1.32 (95% CI, 0.66-2.59) and 3.07 (95% CI, 1.41-6.36), respectively. These values in 106 patients with negative surgical margins were 1.52 (95% CI, 0.51-3.73) and 5.40 (95% CI, 1.25-16.5), and 1.06 (95% CI, 0.45-2.32) and 1.70 (95% CI, 0.49-4.61), respectively. In analysis 2, the 5-year survival rates of patients with 1 to 3, 4 to 9, and 10 or more nodules were 51%, 46%, and 25%, respectively. CONCLUSION Hepatic resection for patients with 4 to 9 nodules clearly is warranted. On the other hand, for patients with 10 or more tumor nodules, surgery cannot be ensured absolutely to be contraindicated in high volume centers at which the surgical mortality rate is nearly zero.

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
OBJECTIVE To determine the risk, the benefit, and the main factors of prognosis of third liver resections for recurrent colorectal metastases. SUMMARY BACKGROUND DATA Recurrence following liver resection is frequent after a first as after a second hepatectomy. Second liver resections yield a similar survival to that obtained with first liver resection, but little is known about third hepatectomy. METHODS This study reports a retrospective analysis of 60 patients who underwent a third liver resection for colorectal metastases in a 16-year experience (1984-2000). Patients were identified from a prospective database that collected 615 consecutive patients who cumulated 883 hepatectomies (615 first, 199 second, 60 thirds, and 9 fourths). Third hepatic resections were compared with first and second procedures, in terms of risk and benefit for the patient. Prognostic factors of survival after third hepatic resection were determined by univariate and multivariate analysis. RESULTS A third hepatic resection was attempted in 68 of 115 of liver recurrences following a second hepatectomy (59%) and achieved in 88% of the cases (60 of 68). There was no intraoperative mortality or postoperative deaths within the 2 months. Fifteen patients developed postoperative complications (25%), a rate similar to that of first and second hepatectomies. Overall 5-year survival was 32% and disease-free survival was 17% after the third resection. Survival compared favorably to that of patients with recurrence following a second hepatectomy who could not be operated (5% at 3 years) or who failed to be resected (15% at 2 years, P = 0.0001). It also compared favorably to that of patients who underwent only two hepatectomies (5-year survival, 27%). When estimated from the time of first hepatectomy, survival was 65% at 5 years for the 60 patients who underwent three hepatic resections. Concomitant extrahepatic tumor was treated in 16 patients (27%) by 11 abdominal procedures and 5 pulmonary resections. By multivariate analysis, tumor size > 30 mm for first liver metastases, presence of extrahepatic tumor at second hepatectomy, and noncurative pattern of third liver resection were independent prognostic factors of reduced survival. CONCLUSIONS Third hepatectomy is safe and provides an additional benefit of survival similar to that of first and second liver resections. It is worthwhile when curative and integrated into an intended multimodal strategy of tumoral eradication.

Abstract
BACKGROUND Primary hepatocellular carcinoma (HCC) and metastases from colorectal cancer are the most common malignant liver tumours. Surgical resection is the optimum treatment in suitable patients. Interstitial laser thermotherapy (ILT) is gaining acceptance for the treatment of irresectable liver tumours and as a potential alternative to surgery. An understanding of the principles of therapy and review of clinical outcomes may allow better use of this technology. METHOD An electronic search using the Medline database was performed for studies on the treatment of hepatic malignancy published between January 1983 and February 2003. RESULTS Current information on the efficacy of ILT is based on prospective studies. ILT appears to be a safe and minimally invasive technique that consistently achieves tumour destruction. The extent of destruction depends on the fibre design, delivery system, tumour size and tumour biology. Real-time magnetic resonance imaging provides the most accurate assessment of laser-induced tumour necrosis. In selected patients with HCC and colorectal cancer liver metastases, ILT achieves complete tumour necrosis, provides long-term local control, and improves survival, compared with the natural history of the disease. In addition, ILT has survival benefits for patients with other tumour types, especially those with isolated liver metastases from a breast cancer primary. CONCLUSION ILT improves overall survival in specific patients with liver tumours. Advances in laser technology and refinements in technique, and a better understanding of the processes involved in laser-induced tissue injury, may allow ILT to replace surgery as the procedure of choice in selected patients with liver malignancies.

Abstract
BACKGROUND The justification for surgical resection of liver metastases from gastric cancer remains controversial. METHODS Twenty-two patients who underwent 26 hepatectomies for liver metastases of gastric cancer between 1985 and 2001 were analyzed. Fifteen clinicopathologic factors were evaluated with univariate and multivariate analyses for survival after hepatic resection. RESULTS The overall 1-year, 3-year, and 5-year survival rates after hepatectomy for gastric metastases were 73%, 38%, and 38%, respectively. Five patients survived for more than 3 years without recurrence, 3 of whom had synchronous metastases resected at the time of gastrectomy. The best results after surgical resection for liver metastases of gastric cancer were obtained with solitary metastases less than 5 cm in size. The number of liver metastases (solitary or multiple) was the only significant prognostic factor according to both univariate and multivariate analyses. CONCLUSION Surgical resection for liver metastases of gastric cancer may be beneficial for patients with a solitary metastasis, whether it is synchronous or metachronous.

Abstract
In 30-50% of patients the liver is a preferred site of distant disease for many malignant tumours. Due to the high incidence, most of the available data relate to metastases arising from colorectal primaries. Surgical resection is at present the only treatment offering potential cure. The achievable 5-year survival rate is 30%. However, only 10-15% of patients with colorectal liver metastases can undergo potentially curative liver resection. Therefore, accurate staging is an important prerequisite in selecting patients who would benefit from surgery. Recurrence of hepatic metastases after potentially curative resection occurs in up to 60% of the cases. Results demonstrate that re-resection of liver metastases can provide long-term survival rates in a carefully selected group of patients without extrahepatic disease. Because of the high rate of recurrences following an apparently curative resection several authors investigated the use of adjuvant chemotherapy (systemic, intraportal, and hepatic arterial infusion). Until recently none had shown effectiveness. Pre-operative chemotherapy seems to be a promising approach in patients with liver metastases initially considered unsuitable for radical surgery. Recently, neoadjuvant chemotherapy has been proposed as an alternative approach to conventional surgery as initial management with the aim of improving the results in resectable liver metastases. Interventional strategies (ethanol injection, cryosurgery, laser-induced thermotherapy, radio-frequency ablation) and combined modalities (surgical/interventional) are additive methods which may help to improve treatment results in the future.

Abstract
OBJECTIVE The purpose of this study was to perform a computer analysis of the size of the thermal injury created by overlapping multiple thermal ablation spheres. MATERIALS AND METHODS A computer-assisted design system was used to create three-dimensional models of a spherical tumor, a spherical tissue volume consisting of the tumor plus a 1-cm tumor-free margin, and individual spherical ablations. These volumes were superimposed in real-time three-dimensional space in different geometric relationships. The effect of the size and geometric configuration of the ablation spheres was analyzed with regard to the ability to ablate the required volume of tissue (tumor plus margin) without leaving untreated areas or interstices. RESULTS The single-ablation model showed that if a 360-degree 1-cm tumor-free margin is included around the tumor targeted for ablation, radiofrequency ablation devices producing 3-, 4-, and 5-cm ablation spheres can be used to treat 1-, 2-, and 3-cm tumors, respectively. The six-sphere model, in which six ablation spheres are placed in orthogonal planes around the tumor, showed that the largest tumor that may be treated with a 3-cm ablation device is 1.75 cm, whereas 4- and 5-cm ablation spheres can be used to treat tumors measuring 3 and 4.25 cm, respectively. The 14- sphere model showed that addition of eight more spheres to the six-sphere model increased the treatable tumor size to 3, 4.6, or 6.3 cm, depending on the diameter of the ablation sphere used. For treating larger tumors, we found a cylindrical model to be less efficient but easier to control. CONCLUSION Our computer analysis showed that the size of the composite thermal injury created by overlapping multiple thermal ablation spheres is surprisingly small relative to the number of ablations performed. These results emphasize the need for a methodic tumor ablation strategy.

Abstract
This study evaluated the risks and benefits of repeat hepatic cryotherapy for recurrent, unresectable hepatic metastases from colorectal carcinoma. Review of a prospective database identified 195 patients who underwent hepatic cryotherapy for metastatic colorectal carcinoma during a 7-year period. Of the 14 patients who underwent successful repeat cryotherapy for recurrences confined to the liver, 86% had Duke's stage D colorectal carcinoma at initial diagnosis. The median age of the 14 patients was 58 years (range 41 to 77 years). The median number of hepatic metastases was three at the first cryotherapy and two at the second cryotherapy. At a median follow-up of 71 months, the mean survival times from original diagnosis, first cryotherapy, and second cryotherapy were 53, 42, and 19 months, respectively. At the most recent follow-up, eight patients (57%) have died of their disease, four (29%) are alive with disease, and two (14%) have no evidence of disease. The mean interval between the first and second cryotherapies was 23 months. The complication rates after the first and second cryotherapies were 7% and 14%, respectively. One patient developed a wound dehiscence after the first cryotherapy. Following the second cryotherapy, one patient had a small bowel obstruction and another had a pleural effusion. There was no perioperative mortality. Repeat cryotherapy for recurrent, unresectable hepatic metastases from colorectal cancer is safe and improves survival. However, a prospective trial is needed to validate the efficacy of systemic therapy and to better define the indications for repeat hepatic cryotherapy.

Abstract
BACKGROUND AND OBJECTIVES After curative resection of hepatic colorectal metastases, 10-20% of patients experience a resectable hepatic recurrence. We wanted to assess the expected risk-to-benefit ratio in comparison to first hepatectomy and to determine the prognostic factors associated with survival. METHODS Twenty-nine patients from a group of 152 patients resected for colorectal liver metastases underwent 32 repeat hepatectomies. RESULTS In-hospital mortality was 3.5% (1/29 patients); the morbidity after repeat hepatectomy was lower than that after first hepatic resection. Combined extrahepatic surgery was performed on 34.5% of repeat hepatectomies vs. 6.9% of first hepatectomies (P = 0.01). Overall actuarial 3-year survival was 35.1%: four patients have survived more than 3 years and one survived for more than 5 years. The number of hepatic metastases and the carcinoembryonic antigen (CEA) serum levels were significant prognostic factors on univariate analysis. The synchronous resection of hepatic and extrahepatic disease was not associated with a lower survival rate when compared with that of patients without extrahepatic localization: three patients of the former group are alive and disease-free at more than 2 years. CONCLUSIONS Repeat hepatic resection can provide long-term survival rates similar to those of first liver resection, with comparable mortality and morbidity. The presence of resectable extrahepatic disease must not be an absolute contraindication to synchronous hepatectomy because long-term survival is possible.

Abstract
BACKGROUND Liver resection for colorectal metastases is the only known treatment associated with long-term survival; extrahepatic disease is usually considered a contraindication to such treatment. However, some surgeons do not regard spread to the hepatic lymph nodes as a contraindication provided that these nodes can be excised adequately. A systematic review of the literature was undertaken to address this issue. METHODS An electronic search using Medline, Cancerlit and Embase databases was performed for studies reporting liver resection for colorectal metastases from 1964 to 1999. Data were extracted from papers reporting outcome for patients with positive hepatic nodes and analysed according to predetermined criteria. RESULTS Fifteen studies were identified that gave survival data on 145 node-positive patients. Five patients were reported to have survived 5 years after liver resection; one was disease free, two had recurrent disease and the disease status was not described in the remaining two. Five studies containing 83 patients specified a formal lymph node dissection as part of the surgical procedure and four of the five node-positive 5-year survivors were from these studies. CONCLUSION There are few 5-year survivors after liver resection, with or without lymph node dissection, for colorectal hepatic metastases involving the hepatic lymph nodes.

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
The battle against malignancies of the liver is far from over, although tremendous strides have been made in the past decade, such as improved diagnostic capabilities, safe surgical resection, availability of safe nonsurgical ablative modalities, multimodality therapy, and aggressive approach to recurrent disease. Even after the best attempts at curative treatment, recurrence of primary and secondary malignancies of the liver continues to be the cause of demise for more than 70% of treated patients. The battle continues in the laboratories, where investigations are focused on delineating the pathophysiology of cancer on the molecular and genetic levels and mapping the patterns of cancer emergence and spread. The new millennium holds promise for formulating therapies that may improve disease-free survival for patients with malignancies of the liver.
