Feasibility of Synchronous Liver Metastasectomy During Emergency Colorectal Surgery: A Case Report. Cureus 2024; 16:e59625. [PMID: 38707759 PMCID: PMC11069123 DOI: 10.7759/cureus.59625] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 05/04/2024] [Indexed: 05/07/2024] Open
Abstract
Colorectal cancer (CRCa) is the most frequent gastrointestinal (GI) malignancy, while the liver is the most common site of distant metastases from CRCa, arising from hematogenous spread mainly via the portal venous system. The multiform nature of tumor presentation necessitates a comprehensive approach to diagnosis, perioperative care, and oncological treatment strategy. Herein, we present a case of a 76-year-old male patient diagnosed with obstructive bowel ileus due to a sigmoid tumor with synchronous, suspicious for metastasis, liver lesion who underwent Hartmann's sigmoidectomy in conjunction with left lateral hepatic resection at the same time. Intraoperatively significant blood loss occurred, while the postoperative course of the patient included pulmonary embolism (PE) six days after the procedure, being discharged on postoperative day (POD) 21. After oncological consensus, the patient underwent adjuvant chemotherapy and his reevaluation nine months after surgery confirmed that he is free of active disease. It is evident, however, that the number of existing studies concerning synchronous metastasectomy alongside CRCa resection in an emergency setting is limited and the literature gaps on this matter emphasize the need for further research.

Abstract
Background Surgical resection is the most efficient treatment for isolated colorectal cancer hepatic metastases. Among the known prognostic factors of this procedure, the impact of the resection margin width is still a controversial matter in the literature. Methods A retrospective cohort study was performed including 170 patients who underwent surgical resection of colorectal cancer liver metastases (CRLMs) between 2006 and 2016 in our hepatobiliary unit. Resection margin width was determined histologically by measuring the distance from the tumour in millimetres or centimetres. Patients' clinical characteristics were also collected. Patients were then stratified in two tumour margin groups: below 5 mm (group A) and equal to or above 5 mm (group B). Overall survival (OS) and disease-free survival (DFS) were the primary outcomes. Results Kaplan-Meier curves showed significantly better outcomes for cases having resection margins above 5 mm for both DFS with 1508.7 days (range 1151.2-1866.2) in group A, compared to 2463.9 days (range 2021.3-2906.5) in group B (P=0.049), and OS with 1557.8 days (range 1276.3-1839.3) for group A and 2303.8 days (range 1921.2--2686.4) for group B (P=0.020). This survival benefit was not significant for patients presenting with stage IV CRC at diagnosis or cases where extended (7+ segments) resections were performed. Conclusion Five-millimetre margins provide a significant survival advantage and should be aimed for in the treatment of CRLMs. Further research on the cause for this finding, including tumour biology's impact on survival, is required.

ENVIRONMENTAL HEALTH INSIGHTS 2022; 16:11786302221112569. [PMID: 35910284 PMCID: PMC9335495 DOI: 10.1177/11786302221112569] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/21/2022] [Accepted: 06/13/2022] [Indexed: 06/15/2023]
Abstract
BACKGROUND Disinfection byproducts (DBPs) from chlorinated drinking water have been linked to an increased risk of cancer in the bladder, stomach, colon, and rectum. No studies showed the independent trends and prevalence of these cancers in Ethiopia. Therefore, this study aimed to determine the prevalence and trends of disinfection byproducts-related cancers in Addis Ababa, Ethiopia. METHODS Data were collected from the Addis Ababa Cancer Registry. Spatial data sets were produced and classified into households receiving chlorinated surface water and less chlorinated groundwater. The Cochran-Armitage trend test was used to evaluate whether there was a disinfection byproducts-related cancers (DBRCs) trend among communities receiving chlorinated water. Negative binomial regression was used to analyze the incidence rate. RESULTS A total of 11, 438 cancer cases were registered between 2012 and 2016, and DBRCs accounted for approximately 17%. The majority of the total cancer cases were female; 7,706 (67%). The prevalence of DBRCs was found to be higher in communities supplied with chlorinated water. From 2012 to 2016, the trend of colon cancer increased (β = 10.3, P value = .034); however, esophageal cancer decreased (β = -6.5, P value = .018). Approximately 56% of colorectal cancer patients and 53% of stomach cancer patients are known to be using chlorinated surface water for drinking regularly. In addition, approximately 57.1% and 54% of kidney and bladder cancer patients, respectively, used chlorinated surface water. CONCLUSION The prevalence of DBRCs in this study was found to be high. The colon cancer trend increased substantially from 2012 to 2016. The prevalence of DBRCs was higher in communities supplied with chlorinated surface water. Similarly, the prevalence of DBRCs was higher among males than females. Further study is required to validate the association between DBRCs and water chlorination.

Abstract
BACKGROUND Synchronous colorectal cancer liver metastasis (CRLM) has been viewed as being more aggressive and having shorter survival than metachronous disease. Advances in CRLM management led us to examine differences in treatment characteristics of synchronous versus metachronous CRLM patients along with survival and recurrence. MATERIALS AND METHODS A retrospective review of hepatic resection for CRLM at a tertiary academic medical center was performed for two periods: a historic cohort from 1992 to 2010 (n = 121), and a modern cohort (n = 179) from 2012 to 2018. Clinical variables were compared between the patient groups, and survival outcomes were characterized. RESULTS Five-year disease-specific survival for the modern synchronous group compared to the historic synchronous group was 71.7% versus 44.3% (P = 0.02). Modern metachronous versus modern synchronous 5-y disease-specific survival rates were 49.8% versus 71.7% (P = 0.31). Compared to the historic cohort, the modern one had significantly different timing of hepatic resection (P < 0.01) with increased use of liver-first (30.1% versus 7.5%) and simultaneous liver-colon resections (24.1% versus 10.4%), along with greater use of neoadjuvant chemotherapy (96.4% versus 65.6%; P < 0.01). Significantly more patients in the modern synchronous cohort had disease-free or alive-with-disease status at last follow-up, compared to the historic group (P < 0.01), and experienced less disease recurrence (62.7% versus 77.6%; P < 0.05). CONCLUSIONS Modern synchronous CRLM patients who underwent hepatic resection experienced significantly improved survival compared to a historic cohort. We postulate that increased use of neoadjuvant chemotherapy and liver-first/simultaneous liver-colon resections in the modern synchronous cohort contributed to improved survival.

Abstract
BACKGROUND Hepatic metastases are a major cause of death in patients with colorectal cancer. A comprehensive assessment of the prognostic factors associated with long-term survival could improve patient selection for surgical approaches and decrease morbidity and futile locoregional treatments. METHODS We performed a retrospective analysis of patients who underwent hepatectomy for colorectal liver metastases at a single center from 2000 to 2012. RESULTS To identify factors associated with 5- and 10-year overall (OS) and disease-free survival (DFS), we analyzed 280 patients and 150 patients in the 5- and 10-year cohorts, respectively. Only seven relapses occurred after 5 years of follow-up, and no relapses occurred after 10 years. Multivariable analysis indicated that bilobar disease and extra-hepatic disease before hepatectomy were independent 5- and 10-year predictors of OS, and major postoperative complications predicted OS in the 5-year survival cohort only. Our analysis indicated that prognostic factors associated with DFS included some confounders and was therefore inconclusive. CONCLUSIONS Taken together, our results suggest that the predictors of 5- and 10-year OS rates of colorectal cancer patients with hepatic metastases are similar, differing only by postoperative complications that influenced exclusively 5-year survival. Since no relapse occurred 10 years after hepatic resection, oncological remission is likely.

Outcomes and prognostic factors after pulmonary metastasectomy in patients with colorectal cancer with previously resected hepatic metastases. J Thorac Cardiovasc Surg 2019; 157:2049-2057.e1.

Abstract
OBJECTIVES Outcomes and prognostic factors remain obscure in patients with colorectal cancer after pulmonary metastasectomy who had previously received a curative hepatic metastasectomy. METHODS We collected data of 757 patients with pulmonary metastasis from colorectal cancer who underwent curative metastasectomy between 2004 and 2008 from 46 Japanese institutions, from which we extracted data on patients who previously received curative hepatic metastasectomy. Disease-free survival, overall survival, and prognostic factors were analyzed. RESULTS The subjects of this study were 160 patients, of whom 44% had primary rectal tumor, 73% had a single pulmonary metastasis, 11% had a bilateral pulmonary metastasis, and 39% had high (>5 ng/mL) serum carcinoembryonic antigen. Patients' median age was 66 years, and 58% were male. The median follow-up was 64 months. Five-year overall survival and disease-free survival were 65.2% (95% confidence interval, 56.8-72.5) and 33.5% (95% confidence interval, 26.1-41.0), respectively. In multivariable analyses, high prethoracotomy carcinoembryonic antigen level was an independent prognostic factor for overall survival (hazard ratio, 2.01; 95% confidence interval, 1.16-3.47) and disease-free survival (hazard ratio, 2.10; 95% confidence interval, 1.41-3.12). Five-year overall survival and disease-free survival of patients with normal prethoracotomy carcinoembryonic antigen level were 76.4% (95% confidence interval, 66.1-83.9) and 40.7% (95% confidence interval, 30.5-50.5), respectively. CONCLUSIONS After pulmonary metastasectomy, approximately two thirds of patients with colorectal cancer with a history of curative hepatic metastasectomy survived for 5 years-half of them disease-free. Our results indicate that patients with colorectal cancer with pulmonary metastasis and a history of curative hepatic metastasectomy may benefit from sequential pulmonary metastasectomy, especially if prethoracotomy serum carcinoembryonic antigen levels are within normal range.

Abstract
Background Recent results from single cell gene and protein regulation studies are starting to uncover the previously underappreciated fact that individual cells within a population exhibit high variability in the expression of mRNA and proteins (i.e., molecular variability). By combining cellular network modeling, and high-throughput gene expression measurements in single cells, we seek to reconcile the high molecular variability in single cells with the relatively low variability in tissue-scale gene and protein expression and the highly coordinated functional responses of tissues to physiological challenges. In this study, we focus on relating the dynamic changes in distributions of hepatic stellate cell (HSC) functional phenotypes to the tightly regulated physiological response of liver regeneration. Results We develop a mathematical model describing contributions of HSC functional phenotype populations to liver regeneration and test model predictions through isolation and transcriptional characterization of single HSCs. We identify and characterize four HSC transcriptional states contributing to liver regeneration, two of which are described for the first time in this work. We show that HSC state populations change in vivo in response to acute challenges (in this case, 70% partial hepatectomy) and chronic challenges (chronic ethanol consumption). Our results indicate that HSCs influence the dynamics of liver regeneration through steady-state tissue preconditioning prior to an acute insult and through dynamic control of cell state balances. Furthermore, our modeling approach provides a framework to understand how balances among cell states influence tissue dynamics. Conclusions Taken together, our combined modeling and experimental studies reveal novel HSC transcriptional states and indicate that baseline differences in HSC phenotypes as well as a dynamic balance of transitions between these phenotypes control liver regeneration responses.

Abstract
The determinants of prognosis in patients with colorectal liver metastases (CLM) have been traditionally searched among the tumoral factors, either of the primary colorectal tumor or of the CLM. While many different scoring systems have been developed based on those clinic-pathological factors with disparate results, there has been the introduction of genetic biological markers that added a theranostic perspective. More recently, other important elements, such as those factors related to the host immune system, have been proposed as determinants of prognosis of CLM patients. In the present work, we review the current prognostic factors of CLM patients as well as the burgeoning shifting paradigm of prognostication that relies on the host immune system.

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
In many cancers, the establishment of a patient’s future treatment regime often relies on histopathological assessment of tumor tissue specimens in order to determine the extent of the ‘pathological response’ to a given therapy. However, histopathological assessment of pathological response remains subjective. Here we use MALDI mass spectrometry imaging to generate lipid signatures from colorectal cancer liver metastasis specimens resected from patients preoperatively treated with chemotherapy. Using these signatures we obtained a unique pathological response score that correlates with prognosis. In addition, we identify single lipid moieties that are overexpressed in different histopathological features of the tumor, which have potential as new biomarkers for assessing response to therapy. These data show that computational methods, focusing on the lipidome, can be used to determine prognostic markers for response to chemotherapy and may potentially improve risk assessment and patient care.

Comparison of Anatomical and Nonanatomical Hepatectomy for Colorectal Liver Metastasis: A Meta-Analysis of 5207 Patients. Sci Rep 2016; 6:32304.

Abstract
It remains unclear whether hepatectomy for colorectal liver metastasis (CRLM) should be performed as anatomical resection (AR) or nonanatomical resection (NAR). The aim of this study is to compare the short- and long-term outcomes of AR and NAR for CRLM. PubMed, Web of Science, EMBASE and the Cochrane Library were systematically searched to identify eligible studies. Twenty one studies involving 5207 patients were analyzed: 3034 (58.3%) underwent AR procedure and 2173 (41.7%) underwent NAR procedure. The results showed that overall survival (OS, hazard ratio (HR) 1.06, 95% confidence interval (CI) 0.95–1.18) and disease free survival (DFS, HR 1.11, 95% CI 0.99–1.24) did not differ significantly between AR and NAR. Duration of operation, postoperative morbidity and mortality were higher in AR than in NAR. There were no significant differences in blood loss and prevalence rate of postoperative positive margins (OR 0.79, 95% CI 0.37–1.52). Our analysis shows that AR does not seem to bring more prognostic benefits than NAR for the treatment of CRLM, and does seem to be inferior to NAR in terms of duration of operation, incidence of postoperative morbidity and mortality.

Abstract
Background: The surgical strategy for the treatment of colorectal cancer and synchronous hepatic metastases remains controversial. Many surgeons fear anastomotic leakage and intraperitoneal abscesses when performing a one-step procedure. They prefer a two-step procedure with a liver resection 2 to 3 months after resection of the colorectal primary lesion. Subjects and Methods: We analysed medical records from April 1994 to April 2002 for a total of 42 patients with colorectal cancer and synchronous liver metastases who underwent simultaneous liver and colorectal resections with a primary anastomosis. Special attention was paid to data on surgical procedures, postoperative morbidity, and mortality. Results: Forty-two patients, 24 men and 18 women, were studied. Median operating time was 6.50 hours (3.75–11.0 hours), and median blood loss was 1522 ml (range 288 to 5650 ml). Postoperative complications included pleural effusion in 4 patients, ileus in 3, anastomotic leakage in 2, intraperitoneal pelvic abscesses in 1, pneumonia in 1, bile leakage in 1, atelectasis in 1, and wound infection in 1. There was no perioperative mortality. Conclusion: Simultaneous colorectal resection with a primary anastomosis and hepatectomy for synchronous liver metastases is considered a safe procedure.

Abstract
BACKGROUND The role of carcinoembryonic antigen (CEA) in surveillance and follow-up of patients with colorectal cancer continues to be debated. The objective of this study was to assess the utility of postoperative CEA as a predictor of recurrence for patients with resected colorectal liver metastases (CLM). METHODS Patients were identified from a prospectively maintained CLM database, and were studied retrospectively. Patients with extrahepatic disease or initially unresectable CLM were excluded. All patients in this study received adjuvant systemic chemotherapy after resection. RESULTS Between 1997 and 2007, a total of 318 consecutive patients were studied, with 168 patients (53 %) experiencing recurrence within 2 years. Various postoperative CEA cutoffs were tested as independent predictors of recurrence. A postoperative CEA ≥15 ng/ml obtained the highest hazard ratio (1.87; 95 % CI 1.09-3.2; p = 0.023) and was chosen to be included in the survival analysis in the multivariate model. A postoperative CEA ≥15 ng/ml had a specificity of 96 % and positive predictive value of 82 % for recurrence. On multivariate analysis, age ≥70 years, the presence of positive lymph node at primary tumor resection, disease-free interval ≤12 months, number of lesions >1, largest lesion ≥5 cm, presence of positive margins, and postoperative CEA ≥15 ng/ml were independent predictors of recurrence within 2 years. CONCLUSION This study demonstrates a postoperative CEA ≥15 ng/ml to be a predictive test for recurrence.

Abstract
Clinical practice with respect to metastatic colorectal cancer differs from the other two most common cancers, breast and lung, in that routine surveillance is recommended with the specific intent of detecting liver and lung metastases and undertaking liver and lung resections for their removal. We trace the history of this approach to colorectal cancer by reviewing evidence for effectiveness from the 1950s to the present day. Our sources included published citation network analyses, the documented proposal for randomised trials, large systematic reviews, and meta-analysis of observational studies. The present consensus position has been adopted on the basis of a large number of observational studies but the randomised trials proposed in the 1980s and 1990s were either not done, or having been done, were not reported. Clinical opinion is the mainstay of current practice but in the absence of randomised trials there remains a possibility of selection bias. Randomised controlled trials (RCTs) are now routine before adoption of a new practice but RCTs are harder to run in evaluation of already established practice. One such trial is recruiting and shows that controlled trial are possible.

Abstract
The use of adjuvant systemic chemotherapy for resectable liver metastases from colorectal cancer (CRC) is controversial because no trial demonstrated its benefit. We conducted the phase III trial to evaluate UFT/leucovorin (LV) for colorectal liver metastases (CRLM). The primary endpoint has not been available until 2014, we first report the feasibility and safety data of UFT/LV arm. In this multicenter trial, patients who underwent curative resection of liver metastases from colorectal cancer were randomly assigned to receive surgery alone or surgery followed by adjuvant chemotherapy with UFT/LV. The primary endpoint was relapse-free survival. Secondary endpoints included overall survival and safety. A total of 180 patients were enrolled, 90 were randomly assigned to receive UFT/LV therapy. Eighty two of whom were included in safety analyses. In the UFT/LV group, the completion rate of UFT/LV was 54.9%, the relative dose intensity was 70.8% and grade 3 or higher adverse events occurred in 12.2% of the patients. Elevated bilirubin levels, decreased hemoglobin levels, elevated alanine aminotransferase levels, diarrhea, anorexia were common. Most other adverse events were grade 2 or lower and tolerable. In conclusions, UFT/LV is a safe regimen for postoperative adjuvant chemotherapy in patients who have undergone resection of liver metastases from colorectal cancer. Further studies are warranted to improve completion rate, but UFT/LV is found to be a promising treatment in this setting.

Abstract
OBJECTIVES Among patients with initially unresectable colorectal cancer liver metastases (CLM), a subset are rendered resectable following the administration of systemic chemotherapy. This study reports the results achieved in liver resections performed at a single hepatobiliary referral centre after downsizing chemotherapy in patients with initially unresectable CLM. METHODS All liver resections for CLM performed over a 10-year period at the Toronto General Hospital were considered. Data on initially non-resectable patients who received systemic therapy and later underwent surgery were included for analysis. RESULTS Between January 2002 and July 2012, 754 liver resections for CLM were performed. A total of 24 patients were found to meet the study inclusion criteria. Bilobar CLM were present in 23 of these 24 patients. The median number of tumours was seven (range: 2-15) and median tumour size was 7.0 cm (range: 1.0-12.8 cm) before systemic therapy. All patients received oxaliplatin- or irinotecan-based chemotherapy. Fourteen patients received combined treatment with bevacizumab. Negative margin (R0) resection was accomplished in 21 of 24 patients. There was no perioperative mortality. Ten patients suffered perioperative morbidity. Eighteen patients suffered recurrence of disease within 9 months. Rates of disease-free survival at 1, 2 and 3 years were 47.6% [95% confidence interval (CI) 30.4-74.6%], 23.8% (95% CI 11.1-51.2%) and 19.0% (95% CI 7.9-46.0%), respectively. Overall survival at 1, 2 and 3 years was 91.5% (95% CI 80.8-100%), 65.3% (95% CI 48.5-88.0%) and 55.2% (95% CI 37.7-80.7%), respectively. CONCLUSIONS Liver resection in initially unresectable CLM can be performed with low rates of morbidity and mortality in patients who respond to systemic chemotherapy, although these patients do experience a high frequency of disease recurrence.

Abstract
BACKGROUND Surgical resection is the most effective treatment for colorectal cancer that has metastasized to the liver. Similarly, surgical resection improves survival for selected patients with pulmonary colorectal metastases. However, the indication for pulmonary metastasectomy is not clear in patients with both hepatic and pulmonary colorectal metastases. Therefore, we evaluated outcomes after pulmonary resection of colorectal metastases in patients with or without a history of curative hepatic metastasectomy. METHODS We retrospectively analyzed 96 patients who underwent pulmonary metastasectomy from March 1999 to November 2009. Patients were grouped according to treatment: resection of pulmonary metastases alone (lung metastasectomy group) or resection of both hepatic and pulmonary metastases (liver and lung metastasectomy group). Overall survival (OS) and disease-free survival (DFS) were evaluated by Kaplan-Meier analysis. Survival curves were compared using the log-rank test. RESULTS The 5-year OS for all patients was 61.3 %, and the 5-year DFS was 26.7 %. Group comparisons showed that the 5-year OS of the lung metastasectomy group was significantly better than that of the liver and lung metastasectomy group (69 vs. 43 %; p = 0.030). However, the 5-year DFS rates of the lung metastasectomy group (25.8 %) and liver and lung metastasectomy group (28.0 %) did not differ significantly. Recurrence was higher after resection of both hepatic and pulmonary metastases than after pulmonary metastases alone (79 vs. 45 %; p = 0.025). CONCLUSIONS Resection of pulmonary colorectal metastases may increase survival. However, the combination of liver and lung metastasectomies had a worse prognosis than pulmonary metastasectomy alone. In selected patients, combined liver and lung metastasectomy can be beneficial and result in acceptable DFS.

Abstract
PURPOSE Despite recent improvement of the outcomes of colorectal cancer (CRC), the benefits of resection and appropriate selection criteria in patients with both liver and lung metastases remain controversial. The aim of this study was to analyze the outcomes and prognostic factors for survival in patients who underwent both hepatic and pulmonary resection for CRC metastases in the era of modern multidisciplinary therapy. METHODS A retrospective analysis of 43 consecutive patients who underwent both liver and lung resections for metastatic CRC at our institute from 2003 to 2011 was performed. All patients in this study had achieved cancer-free status after resection of the second metastatic site. RESULTS Of the patients, 24 (56 %) had synchronous metastatic disease with their primary tumor. Twenty-seven patients had developed recurrence after resection of the second metastatic site. In 14 cases, re-metastasectomy was performed for recurrence. Fourteen patients received palliative chemotherapy after recurrence, and all of these patients received oxaliplatin and/or irinotecan-based chemotherapy. After resection of the second metastatic organ, the 5-year relapse-free and overall survival rates were 29.6 and 70.0 %, respectively. Patients with multiple lung metastases had worse relapse-free survival than patients with solitary lung metastases at first lung resection (p = 0.046). CONCLUSIONS Aggressive surgical resection and a combination of modern chemotherapeutic agents improve the survival of patients with lung and liver metastases from CRC. The presence of multiple lung metastases at resection suggests a poor prognosis.

Abstract
Despite improvements in the multi-modality treatment of colorectal liver metastasis (CRLM), survival after resection remains varied. Determining prognosis after surgical resection has historically been predicated on preoperative clinicopathological factors such as primary tumor stage, carcinoembryonic antigen levels, number of liver metastases, presence of extrahepatic disease, as well as other factors. While scoring systems have been developed by combining certain preoperative factors, these have been inconsistent in accurately determining prognosis. There has been increasing interest in the use of biologic and molecular markers to predict prognosis following CRLM. The role of markers such as KRAS, BRAF, p53, human telomerase reverse transcriptase, thymidylate synthase, Ki-67, and hypoxia inducible factor-1α and their correlation with accurately predicting survival after surgical resection have been supported by several studies. Furthermore, other elements such as pathological response to chemotherapy and the presence of circulating tumor cells have shown promise in accurately determining prognosis after resection for colorectal liver metastasis. We herein review past, present, and possible future markers of prognosis among colorectal cancer patients with liver metastasis undergoing resection with curative intent.

Abstract
CONTEXT Liver metastases are a common event in the clinical outcome of patients with colorectal cancer and account for 2/3 of deaths from this disease. There is considerable controversy among the data in the literature regarding the results of surgical treatment and prognostic factors of survival, and no analysis have been done in a large cohort of patients in Brazil. OBJECTIVES To characterize the results of surgical treatment of patients with colorectal liver metastases, and to establish prognostic factors of survival in a Brazilian population. METHOD This was a retrospective study of patients undergoing liver resection for colorectal metastases in a tertiary cancer hospital from 1998 to 2009. We analyzed epidemiologic variables and the clinical characteristics of primary tumors, metastatic disease and its treatment, surgical procedures and follow-up, and survival results. Survival analyzes were done by the Kaplan-Meier method and the log-rank test was applied to determine the influence of variables on overall and disease-free survival. All variables associated with survival with P<0.20 in univariate analysis, were included in multivariate analysis using a Cox proportional hazard regression model. RESULTS During the period analyzed, 209 procedures were performed on 170 patients. Postope-rative mortality in 90 days was 2.9% and 5-year overall survival was 64.9%. Its independent prognostic factors were the presence of extrahepatic disease at diagnosis of liver metastases, bilateral nodules and the occurrence of major complications after liver surgery. The estimated 5-year disease-free survival was 39.1% and its prognostic factors included R1 resection, extrahepatic disease, bilateral nodules, lymph node involvement in the primary tumor and primary tumors located in the rectum. CONCLUSION Liver resection for colorectal metastases is safe and effective and the analysis of prognostic factors of survival in a large cohort of Brazilian patients showed similar results to those pointed in international series. The occurrence of major postoperative complications appears to be able to compromise overall survival and further investigation in needed in this topic.

Abstract
BACKGROUND Liver resection for metastatic colorectal cancer became established without randomized trials. Proponents of surgical resection point out 5-year survival approaching 50% whilst critics question how much of the apparent effect is due to patient selection. METHOD A 2006 systematic review of reported outcomes provided the starting point for citation analysis followed by thematic analysis of the texts of the most cited papers. RESULTS 54 reports from 1988 to 2002 cited 709 unique publications a total of 1714 times. The 15 most cited papers were explored in detail, and showed clear examples of duplicate reporting and overlapping data sets. Textual analysis revealed proposals for a randomized controlled trial, but this was argued to be unethical by others, and no trial was undertaken. CONCLUSIONS This critical review reveals how the case for this surgery was made, and examines the arguments that influenced acceptance and adoption of this surgery.

Abstract
BACKGROUND Liver resection is a possibly curative treatment for colorectal cancer (CRC) liver metastases. Preoperative chemotherapy may make initially irresectable tumors resectable. The aim of this study was to compare perioperative course and short-term mortality after liver resection for CRC metastases between patients who were and were not treated with preoperative chemotherapy. METHODS Patients who had undergone liver resection for CRC metastases were included. A total of 97 patients treated with preoperative chemotherapy (group A) were compared with 136 who were not (group B). Intraoperative bleeding, operating time, complications, duration of stay, and mortality were compared using Pearson's χ(2) test, Fisher's exact test, and the Mann-Whitney U-test. RESULTS Mean intraoperative bleeding, duration of stay, and operating time were not significantly different. Complications occurred in 62.9% and 63.2% in groups A and B, respectively. The 30- and 90-day mortality rates were zero in group A, comparable to 1.5% in group B. CONCLUSIONS There were no significant differences in the perioperative course or postoperative mortality when comparing CRC patients with or without chemotherapy prior to liver resection. Consequently, this study suggests that preoperative chemotherapy before liver resection for CRC metastases does not negatively influence perioperative outcome and can therefore be applied if "downstaging" is indicated.

Abstract
Resection of lung metastases from colorectal cancer (CRC) is increasingly performed with a curative intent. This strategy was made possible in the 1990s by the development of new chemotherapeutic approaches, improved surgical techniques and better imaging modalities. However, evidence-based data showing clinical benefits of lung metastasectomy in this setting are nonexistent, and there are no prospective randomized trials to support the routine performance of these procedures for stage IV CRC. Current evidence suggests that resection of pulmonary metastases in combination with new cytotoxic agents, such as oxaliplatin, irinotecan and bevacizumab, may result in prolonged survival for many, and cure for a small minority of CRC patients who experienced tumor spread beyond the limits of the abdomen. This review focuses on the results of surgical management of CRC patients with lung metastases: we report the outcome of published series according to the presence or the absence of liver metastasis (and hepatic resection) prior to lung resection.

[PMID: 26388907 PMCID: PMC4574986 DOI: 10.14701/kjhbps.2012.16.2.55] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/04/2012] [Revised: 05/23/2012] [Accepted: 05/25/2012] [Indexed: 01/16/2023]
Abstract
BACKGROUNDS/AIMS Prognostic factors for colorectal cancer with hepatic metastasis are not well-established. We investigated the factors that predicted survival following surgical resection of hepatic metastases in patients with colorectal cancer. METHODS Fifty-three patients underwent resection of hepatic metastases of colorectal cancer between January 2000 and December 2005, with follow-up periods that ranged from 3 to 119 months. In this retrospective study, the effects of sex, age, type of hepatic resection, T stage and N stage of the primary cancer, number and size of metastatic hepatic tumors, synchronicity or metachronicity of the liver metastases, surgical resection margins, and preoperative carcinoembryonic antigen (CEA) levels on 1-year and 3-year survival were analyzed using the Kaplan-Meier method and the log rank test. RESULTS Median survival was 39.9 months and the 3-year survival rate was 62.2%. Twenty patients died during the follow-up period of 3 to 119 months (mean, 48.8±34.24). In univariate analysis, only the surgical margin of the hepatic metastasis resection correlated significantly with 3-year survival. Sex, age, T stage and N stage of the primary cancer, synchronicity or metachronicity of the metastases, number and size of hepatic metastases, type of hepatic resection and preoperative CEA levels did not predict long-term outcome. CONCLUSIONS Hepatic resection provides a safe and effective treatment in patients with hepatic metastasis from colorectal cancer. In this study, only the surgical resection margin of the hepatic metastasis of colorectal cancer significantly predicted survival.

Abstract
SUMMARY Disease recurrence continues to be a major cause of death in patients with resected stage II and III colorectal cancer. Distant and local relapses, unless successfully treated surgically, result in patient demise within 5 years in approximately 90% of patients. By contrast, patients who undergo curative-intent surgery and enter surgical remission experience 40–50% 5-year survival. Effective surveillance strategies are needed to improve the rate of colorectal cancer recurrence detection and maximize the chances of curative resections. In this article, we review the strength and shortfalls of the supportive data for intensive surveillance and reflect on the recommendations of various medical associations.

Abstract
BACKGROUND Complex hepatobiliary surgical procedures for benign and malignant conditions are regularly performed at tertiary academic referral centers with excellent outcomes, but whether similar surgical outcomes are achievable in community hospitals is not well documented. METHODS Eighty-four patients underwent complex hepatobiliary surgery between December 2004 and December 2008. Data were prospectively analyzed, including patient demographics, operative procedures, perioperative parameters, pathology, complications up to 30 days postoperatively, and long-term outcomes. RESULTS The most frequent procedures performed were isolated segmentectomy or segmentectomies (n = 41 [49%]). Major hepatic resections (n = 32 [38%]) included 25 lobectomies (30%) and 7 trisegmentectomies (8%). Nine patients (11%) had surgical complications, and the most common indications for surgery was metastatic carcinoma (n = 42 [50%]). CONCLUSIONS Complex hepatobiliary surgery can be performed safely at a community-based teaching hospital with excellent outcomes. In the ongoing debate centering on mandatory referral and centralization of complex surgical procedures, tertiary community hospitals with well-determined outcomes should be included.

Abstract
Improvements with systemic therapy in controlling occult metastatic disease in patients with colorectal cancer and other solid malignancies have raised renewed interest in local therapies that can treat isolated or "oligo" sites of metastatic disease within the liver. Radiotherapy (RT) is a treatment option that can be offered to patients unsuitable for surgery or other ablative therapies. Technological advances in RT planning and delivery have made it possible to administer high doses conformally around focal liver metastases effectively. Methods to facilitate safe delivery of high-dose RT include conformal RT planning, stereotactic body RT, breathing motion management, and image-guided RT. The clinical experience in conformal RT and stereotactic body RT for liver metastases is emerging, with phase I and II trials demonstrating excellent local control and occasional long-term survivors. With appropriate patient selection and sparing of the uninvolved liver, serious toxicity can be avoided. Out-of-field recurrences are common, providing rationale for combining systemic or regional therapies with RT for these patients. Finally, randomized trials of RT for liver metastases are needed to better define the benefits of RT for these patients.

Abstract
Metastatic colorectal cancer traditionally has been considered incurable. Over the past 3 decades, however, resection of low-volume hepatic disease has been recognized as beneficial in some cases. More recently, resection of isolated pulmonary metastases has been shown to offer long-term survival in carefully selected patients. Resection of metastases to more unusual sites (ovary, brain, peritoneal cavity) is more controversial; nevertheless, retrospective data suggest that a few patients may be cured with resection of these tumors. In this article, we review the history and current status of metastasectomy in stage IV colorectal cancer.

Abstract
BACKGROUND Surgical resection of colorectal liver metastases (CLM) is an established form of treatment. Limited data exists on the value of sequential hepatic and pulmonary metastasectomy. We analysed patients who underwent sequential liver and lung resections for CLM. METHODS A total of 910 patients who underwent liver resection for CLM between January 2000 and December 2007, were analysed to identify patients with resectable pulmonary metastases (n= 43; 4.7%). Patient demographics, overall survival and survival difference between synchronous and metachronous pulmonary metastasectomy groups were compared. In addition, outcomes in the 'liver and lung resection' group were compared with a matched group of 'liver resection only' patients (matched for age, primary disease stage, interval to liver resection and liver disease stage). RESULTS Forty-three patients (median age 62, range 43-83 years, 22 males) underwent sequential liver and lung resection. A total of 36 patients underwent major hepatic resections, 18 patients had bilobar disease and the median number of liver lesions resected was 3 (range 1-5 lesions). Ten patients had synchronous liver and lung metastases. The median interval between liver and lung metastasectomy was 25 months (range 2-88 months). A total of two patients underwent major lobectomies, three patients had bilateral disease and the median number of lung lesions resected was one (range 1-3). The 1-, 3- and 5-year overall survival rates after first metastasectomy were 100%, 87.1% and 53.9%, respectively, with a median survival of 42 months. PATIENTS Undergoing metachronous pulmonary metastasectomy had better 1-, 3- and 5-year survival rates than those with synchronous disease (100%, 88.9% and 60.9% vs. 100%, 75% and 0%, respectively; P= 0.02, log rank test). There was no significant survival difference between the 'liver and lung resection' and the 'liver resection only' groups. CONCLUSION Sequential liver and lung resection for CLM is associated with good long-term survival in selected patients, except in those presenting with synchronous lung and liver metastases.

Yttrium-90 radioembolization for liver malignancies: prognostic factors associated with survival. J Vasc Interv Radiol 2009; 21:90-5. [PMID: 19939705 DOI: 10.1016/j.jvir.2009.09.011] [Citation(s) in RCA: 33] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/10/2008] [Revised: 08/19/2009] [Accepted: 09/09/2009] [Indexed: 10/20/2022] Open
Abstract
PURPOSE To identify key prognostic clinical and imaging variables in patients undergoing yttrium-90 radioembolization ((90)Y) for liver malignancies. MATERIALS AND METHODS Patients with liver malignancies that progressed despite standard-of-care therapy were treated with (90)Y from 2002 to 2006. Baseline functional status, laboratory values, and diagnostic imaging were assessed before therapy. Imaging follow-up was performed 1 month after treatment and subsequently at 3-month intervals. Patients were followed for survival from the time of their first (90)Y treatment. RESULTS Patients with follow-up imaging after radioembolization (N = 130) were included in this analysis. Primary malignancies included colon, neuroendocrine, and others. The following clinical variables had a significant effect on survival on multivariate analysis: Eastern Cooperative Oncology Group (ECOG) performance status (PS) greater than 0 (hazard ratio [HR], 7.98; 95% CI, 3.98-16), hepatic tumor burden of 51%-75% (HR, 2.46; 95% CI, 1.01-6.02), bilirubin level greater than 1.3 mg/dL (HR, 2.60; 95% CI, 1.27-5.34), hepatic metastases from breast cancer (HR, 2.51; 95% CI, 1.13-5.61), response on imaging based on World Health Organization (WHO) criteria (HR, 0.48; 95% CI, 0.24-0.94), and lymphocyte depression (HR, 0.56; 95% CI, 0.31-0.96). Among patients with colorectal cancer metastases to the liver, the HR for survival on univariate analysis for responders compared with nonresponders (per WHO criteria) was 0.26 (95% CI, 0.10-0.69). CONCLUSIONS Cancer-related symptoms (ie, ECOG PS > 0), hepatic tumor burden greater than 50%, increased bilirubin levels, and hepatic metastases from breast cancer were found to be negative prognostic factors. Tumor response to therapy and lymphocyte depression were associated with favorable prognosis. Additionally, WHO response was identified to be a favorable prognostic factor in patients with colorectal cancer metastases. These findings may be useful when counseling patients regarding prognosis of their hepatic disease.

Abstract
PURPOSE To review the evidence about the efficacy and utility of radiofrequency ablation (RFA) for hepatic metastases from colorectal cancer (CRHM). METHODS The American Society of Clinical Oncology (ASCO) convened a panel to conduct and analyze a comprehensive systematic review of the RFA literature from Medline and the Cochrane Collaboration Library. RESULTS Because data were considered insufficient to form the basis of a practice guideline, ASCO has instead published a clinical evidence review. The evidence is from single-arm, retrospective, and prospective trials. No randomized controlled trials have been included. The following three clinical issues were considered by the panel: the efficacy of surgical hepatic resection versus RFA for resectable tumors; the utility of RFA for unresectable tumors; and RFA approaches (open, laparoscopic, or percutaneous). Evidence suggests that hepatic resection improves overall survival (OS), particularly for patients with resectable tumors without extrahepatic disease. Careful patient and tumor selection is discussed at length in the literature. RFA investigators report a wide variability in the 5-year survival rate (14% to 55%) and local tumor recurrence rate (3.6% to 60%). The reported mortality rate was low (0% to 2%), and the major complications rate was commonly reported to be between 6% and 9%. RFA is currently performed with all three approaches. CONCLUSION There is a compelling need for more research to determine the efficacy and utility of RFA to increase local recurrence-free, progression-free, and disease-free survival as well as OS for patients with CRHM. Clinical trials have established that hepatic resection can improve OS for patients with resectable CRHM.

Abstract
BACKGROUND Patients with synchronous colorectal liver metastases (CLM) are typically treated with initial colorectal resection followed by arbitrary and prolonged courses of chemotherapy. Partial hepatectomy is considered only for patients without interval disease progression. This review describes the rationale for this treatment approach and the recent developments suggesting that this management paradigm should be reconsidered. RESULTS Because asymptomatic colorectal cancer often does not lead to complications, and given the potential benefit of chemotherapy in downsizing unresectable to resectable liver disease, most patients with asymptomatic primary tumors and unresectable synchronous CLM should be first treated with chemotherapy. In contrast, initial hepatic resection should be considered for resectable synchronous CLM. Survival benefits from prehepatectomy chemotherapy have not been established. Several reports demonstrate morbidity after hepatic resection from extended durations of irinotecan- and/or oxaliplatin-based prehepatectomy chemotherapy. Although shorter treatment periods may not have these deleterious effects on subsequent hepatic resection, prospective studies reveal that most patients with supposedly aggressive disease with short treatment durations will not be identified. Moreover, a complete radiologic response to prehepatectomy chemotherapy is not only rare but also does not equate with a complete pathological response. Finally, several studies suggest that simultaneous colorectal and minor hepatic resections can performed safely with benefits in total morbidity when compared with traditional staged procedures. CONCLUSIONS The traditional treatment paradigm centering on the utility of prehepatectomy chemotherapy for resectable synchronous CLM should be reconsidered. Recent developments underscore the need for prospective randomized controlled trials evaluating the optimal timing of hepatectomy relative to chemotherapy.

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

Abstract
PURPOSE Liver metastases develop in 50 percent of patients with colorectal carcinoma. Recurrent liver disease is usual. Repeat liver resection remains the only curative treatment. The aim of this study was to review our data on repeat hepatectomy and to analyze potential prognostic factors of survival. METHOD Patients who underwent repeat liver resection for metastases of colorectal carcinoma between January 1992 and August 2007 were identified from a prospective database and their medical records were analyzed. RESULTS Of 62 patients who underwent a second hepatectomy, 15 underwent a third hepatectomy, and two underwent a fourth hepatectomy. There was no perioperative mortality. Morbidity was less than 20 percent for the first and second hepatectomies. Overall 5-year survival rate after first hepatectomy was 40 percent. Univariate analysis identified three risk factors confirmed by log-rank test and multivariate Cox regression analysis: serum carcinoembryonic antigen concentrations >5 ng/ml at first hepatectomy (HR = 2.265; CI = 1.140-4.497; P = 0.020), anatomic resection (HR = 2.124; CI = 1.069-4.218; P = 0.031), and tumors > or =3 cm at the second resection (HR = 2.039; CI = 1.013-4.103; P = 0.046). CONCLUSION Our study shows that repeat hepatectomy for liver metastases of colorectal carcinoma may be performed with low mortality and morbidity. Preoperative concentration of carcinoembryonic antigen at first hepatectomy, tumor size, and type of anatomic resection are independent prognostic factors.

Abstract
BACKGROUND Prognosis of patients following resection of CRC metastases to the liver has traditionally been predicted by clinical risk factors. In the era of neoadjuvant chemotherapy, determination of new prognostic indicators of outcome are necessary. METHODS This retrospective study includes patients with CRC liver metastases, who received oxaliplatin or irinotecan based neoadjuvant chemotherapy and underwent R0 resection. Patients were followed by CT and PET-CT, before, during and after chemotherapy and surgery. The predictive value of the Memorial Sloan-Kettering Cancer Center Clinical Score (MSKCC-CS) and degree of response to chemotherapy (measured by CT and PET-CT), were analyzed by univariate and multivariate COX regression. RESULTS Included are 54 patients. Overall 1-, 2-, 3-year survival rates 88%, 70%, and 39%. Response to chemotherapy on CT was a significant predictor of survival on univariate (P = 0.03) and multivariate analysis (P = 0.03), whereas MSKCC-CS and response to chemotherapy on PET-CT were not. Multivariate analysis demonstrated response to chemotherapy as a predictor of time to recurrence on CT (P = 0.02) and PET-CT (P = 0.03), while the MSKCC-CS (P = 0.64) was not. CONCLUSIONS In this cohort of patients treated by neoadjuvant chemotherapy, the outcome was not predicted by the traditional clinical scoring system, but rather by response to chemotherapy as evaluated by CT and PET-CT.

Abstract
BACKGROUND A safety margin of > or =10 mm is generally accepted in surgery for colorectal metastases. It is reasonable that modern methods of liver parenchyma dissection may allow for a reduction in this distance. METHODS A total of 333 patients were included in a multicenter trial after resection of colorectal liver metastases. Dissection of the liver had been performed with a CUSA, UltraCision, or water-jet dissector. The size of the resection margin was correlated with recurrence risk and survival. RESULTS The median hepatic recurrence-free survival reached 35 months for all patients; median recurrence-free survival was 24 months and overall survival was 41 months. Univariate analysis of different groups denoting the extent of resection margin (> or =10 mm, 6-9 mm, 3-5 mm, 1-2 mm, 0 mm (R1)) indicated that a margin of 1-2 mm leads to a significantly reduced median hepatic recurrence-free survival of 20 months (p = 0.004) and recurrence-free survival of 19 months (p = 0.011). Patients with R1 resection had the worst prognosis. Overall survival was not influenced by the size of the resection margin. Surgical margins were significantly reduced in simultaneous resections of four or more liver metastases and in cases in which metastatic infiltration of central liver segments was present. At multivariate analysis, resection margins of 1-2 mm and 0 mm were independent predictors of hepatic recurrence and overall recurrence. CONCLUSION The indication for resection of metastases can be safely extended to cases in which tumors sit closer than 1 cm to nonresectable structures.

Multiagent chemotherapy for isolated colorectal liver metastases: a single-centered retrospective study. J Gastrointest Surg 2009; 13:74-84. [PMID: 18685900 DOI: 10.1007/s11605-008-0617-5] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/23/2008] [Accepted: 07/15/2008] [Indexed: 01/31/2023]
Abstract
BACKGROUND Few studies identifying variables associated with prognosis after resection of colorectal liver metastases (CLM) account for treatment with multiagent chemotherapy (fluoropyrmidines with irinotecan, oxaliplatin, bevacizumab, and/or cetuximab). The objective of this retrospective study was to determine the effect of multiagent chemotherapy on long-term survival after resection of CLM. METHODS Demographics, clinicopathologic tumor characteristics, treatments, and long-term outcomes were reviewed. RESULTS From 1996 to 2006, 230 patients underwent resection of CLM. Treatment strategies before and after resection included fluoropyrimidine monotherapy (n = 34 and n = 39), multiagent chemotherapy (n = 81 and n = 73), and observation (n = 115 and n = 118). Prehepatectomy treatment strategy was not associated with overall survival. Actuarial 4-year survival was 63%, 39%, and 40% for patients treated with multiagent chemotherapy, fluoropyrimidine monotherapy, and observation after hepatectomy, p = 0.06. Posthepatectomy multiagent chemotherapy (p = 0.04, HR 0.52 [0.27-1.03]), duration of posthepatectomy chemotherapy treatment of 2 months or longer (p = 0.05, HR 0.49 [0.25-0.99]), carcino-embryonic antigen level >10 ng/mL (p = 0.03, HR 2.09, 95% CI [1.32-3.32]), and node positive primary tumor (p = 0.002, HR 1.79 [1.06-3.02]) were associated with overall survival in multivariate analysis. CONCLUSIONS The association of posthepatectomy multiagent chemotherapy with overall survival in this retrospective study indicates the need for prospective randomized trials comparing multiagent chemotherapy and fluoropyrimidine monotherapy for CLM.

Unique site- and time-specific patterns of recurrence following resection of colorectal carcinoma hepatic metastases in patients staged by FDG-PET. ACTA ACUST UNITED AC 2008; 15:483-7.

Abstract
BACKGROUND/PURPOSE We recently reported that patients staged by positron emission tomography (PET) with F-18 fluorodeoxyglucose (FDG) prior to liver resection for metastatic colorectal cancer had an excellent 5-year survival. In this study, the site- and time-specific patterns of recurrence were examined in patients staged by FDG-PET and the results compared to historical literature control data. METHODS From March 1995 to June 2002, all patients having hepatic resection for colorectal cancer metastases had preoperative FDG-PET. A prospective database was maintained. RESULTS One hundred patients were studied; 48 patients had no evidence of recurrence, 30 patients had recurrence within 12 months of resection, and 22 patients had recurrence after 12 months. Seventy percent of patients with recurrence within 1 year of resection had intrahepatic recurrence. Furthermore, 86% of patients with recurrence more than 1 year after resection had extrahepatic recurrence. We reviewed all published case series of conventionally staged patients. This pattern of early recurrence in the liver and later recurrence in extrahepatic sites has not been reported in any of the conventionally staged series. CONCLUSIONS There is an interesting difference in the pattern of recurrence of FDG-PET-staged patients and conventionally staged patients who undergo liver resection. Several explanations seem possible. One potential explanation requiring further study is that the pattern of recurrence is due to the convergence of two factors-that FDG-PET more effectively detects extrahepatic disease than conventional staging and that liver resection gives a growth spurt to hepatic metastases.

Abstract
Although prospective, randomized clinical trials never have been conducted, retrospective and comparative studies strongly indicate that hepatic resection is the only available treatment that allows long-term survival in colorectal carcinoma that has metastasized to the liver. Unfortunately, curative resection can be performed in less than 25% of the patients. Ten years ago, hepatic resection was contraindicated in case of multiple or bilobar nodules. Currently, the trend is to be more aggressive and to increase the indications for surgical resection with the development of new strategies using a multidisciplinary approach.

Abstract
The field of surgery for liver metastases is evolving rapidly. The proportion of patients viewed as amenable to resection is increasing with surgeons becoming more aggressive and systemic therapy more effective. Surgical resection is associated with low mortality and overall 5-year survival approaching 40%. Best candidates for resection are those with stage I or II colorectal cancer, fewer than 4 hepatic lesions, no lesions larger than 5 cm in diameter, no evidence of extra-hepatic disease, CEA level less than 5 ng/mL, and a disease-free interval of at least 2 years. Perioperative chemotherapy with or without biotherapies, in-situ ablation techniques, portal vein embolization, and staged hepatectomy have extended the indications without lessening the results of liver resection for colorectal metastases.
