Optimizing Loco Regional Management of Oligometastatic Colorectal Cancer: Technical Aspects and Biomarkers, Two Sides of the Same Coin. Cancers (Basel) 2021; 13:cancers13112617. [PMID: 34073585 PMCID: PMC8198296 DOI: 10.3390/cancers13112617] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/22/2021] [Revised: 05/21/2021] [Accepted: 05/22/2021] [Indexed: 11/23/2022] Open
Abstract
Simple Summary The treatments for patients with oligometastatic colorectal carcinoma are rapidly evolving. The present review focuses on the role of minimally invasive techniques since they can now be used as an alternative to surgical management in selected cases in association with systemic therapies according to ESMO and NCCN guidelines. In recent years, biomarkers (both at molecular and imaging level) have emerged as a relevant and potential criteria for treatment strategy decision and will be crucial in the future for patients selection. Tumor molecular profile impacts on local outcome of image guide ablation as well as metabolic imaging which predicts the outcome of both percutaneous and trans-arterial treatments. Oncologists should be aware of advantages and disadvantages of those treatments options as well as the potential role of molecular profile for a better patient selection. Abstract Colorectal cancer (CRC) is the third most common cancer worldwide and has a high rate of metastatic disease which is the main cause of CRC-related death. Oligometastatic disease is a clinical condition recently included in ESMO guidelines that can benefit from a more aggressive locoregional approach. This review focuses the attention on colorectal liver metastases (CRLM) and highlights recommendations and therapeutic locoregional strategies drawn from the current literature and consensus conferences. The different percutaneous therapies (radiofrequency ablation, microwave ablation, irreversible electroporation) as well as trans-arterial approaches (chemoembolization and radioembolization) are discussed. Ablation margins, the choice of the imaging guidance as well as characteristics of the different ablation techniques and other technical aspects are analyzed. A specific attention is then paid to the increasing role of biomarkers (in particular molecular profiling) and their role in the selection of the proper treatment for the right patient. In conclusion, in this review an up-to-date state of the art of the application of locoregional treatments on CRLM is provided, highlighting both technical aspects and the role of biomarkers, two sides of the same coin.

Abstract
Background Minimally invasive techniques have increasingly found their way into liver surgery in recent years. A multitude of mostly retrospective analyses suggests several advantages of laparoscopic over open liver surgery. Due to the speed and variety of simultaneous technical and strategic developments, it is difficult to maintain an overview of the current status and perspectives in laparoscopic liver surgery. Purpose This review highlights up-to-date aspects in laparoscopic liver surgery. We discuss established indications with regard to their development over time as well as continuing limitations of applied techniques. We give an assessment based on the current literature and according to our own center experiences, not least with regard to a highly topical cost discussion. Conclusions While in the beginning mainly benign tumors were laparoscopically operated on, liver metastasis and hepatocellular carcinoma are now among the most frequent indications. Technical limitations remain and should be evaluated with the overall aim not to endanger quality standards in open surgery. Financial aspects cannot be neglected with the necessity of cost-covering reimbursement.

Abstract
The nuances of determining resectability for liver tumors can be difficult to navigate, owing to the variety of primary and secondary malignancies involving the liver, the range of patient-specific factors to consider, and the hepatic anatomic and functional variability that seems inevitable. The basic principles, however, are simple;if surgery is deemed appropriate from an oncologic standpoint, the patient is in reasonably good health, and the tumor can be safely removed without compromising the integrity of the future remnant, nearly all patients will be candidates for resection.

Abstract
OBJECTIVE To compare the prognostic performance of American Joint Committee on Cancer/International Union Against Cancer seventh N stage relative to lymph node ratio (LNR), log odds of metastatic lymph nodes (LODDS), and N score in gastric adenocarcinoma. BACKGROUND Metastatic disease to the regional LN basin is a strong predictor of worse long-term outcome following curative intent resection of gastric adenocarcinoma. METHODS A total of 804 patients who underwent surgical resection of gastric adenocarcinoma were identified from a multi-institutional database. The relative discriminative abilities of the different LN staging/scoring systems were assessed using the Akaike's Information Criterion (AIC) and the Harrell's concordance index (c statistic). RESULTS Of the 804 patients, 333 (41.4%) had no lymph node metastasis, whereas 471 (58.6%) had lymph node metastasis. Patients with ≥N1 disease had an increased risk of death (hazards ratio = 2.09, 95% confidence interval: 1.68-2.61; P < 0.001]. When assessed using categorical cutoff values, LNR had a somewhat better prognostic performance (C index: 0.630; AIC: 4321.9) than the American Joint Committee on Cancer seventh edition (C index: 0.615; AIC: 4341.9), LODDS (C index: 0.615; AIC: 4323.4), or N score (C index: 0.620; AIC: 4324.6). When LN status was modeled as a continuous variable, the LODDS staging system (C index: 0.636; AIC: 4304.0) outperformed other staging/scoring systems including the N score (C index: 0.632; AIC: 4308.4) and LNR (C index: 0.631; AIC: 4225.8). Among patients with LNR scores of 0 or 1, there was a residual heterogeneity of outcomes that was better stratified and characterized by the LODDS. CONCLUSIONS When assessed as a categorical variable, LNR was the most powerful manner to stratify patients on the basis of LN status. LODDS was a better predicator of survival when LN status was modeled as a continuous variable, especially among those patients with either very low or high LNR.

Abstract
Colorectal cancer is the third most common malignancy in the USA and continues to pose a significant epidemiologic problem, despite major advances in the treatment of patients with advanced disease. Up to 50 % of patients will develop metastatic disease at some point during the course of their disease, with the liver being the most common site of metastatic disease. In this review, we address the relatively poorly defined entity of borderline-resectable colorectal liver metastases. The workup and staging of borderline-resectable disease are discussed. We then discuss management strategies, including surgical techniques and medical therapies, which are currently utilized in order to improve resectability.

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
BACKGROUND Comparative trials evaluating management strategies for colorectal cancer liver metastases (CLM) are lacking, especially for older patients. This study developed a decision-analytic model to quantify outcomes associated with treatment strategies for CLM in older patients. METHODS A Markov-decision model was built to examine the effect on life expectancy (LE) and quality-adjusted life expectancy (QALE) for best supportive care (BSC), systemic chemotherapy (SC), radiofrequency ablation (RFA) and hepatic resection (HR). The baseline patient cohort assumptions included healthy 70-year-old CLM patients after a primary cancer resection. Event and transition probabilities and utilities were derived from a literature review. Deterministic and probabilistic sensitivity analyses were performed on all study parameters. RESULTS In base case analysis, BSC, SC, RFA and HR yielded LEs of 11.9, 23.1, 34.8 and 37.0 months, and QALEs of 7.8, 13.2, 22.0 and 25.0 months, respectively. Model results were sensitive to age, comorbidity, length of model simulation and utility after HR. Probabilistic sensitivity analysis showed increasing preference for RFA over HR with increasing patient age. CONCLUSIONS HR may be optimal for healthy 70-year-old patients with CLM. In older patients with comorbidities, RFA may provide better LE and QALE. Treatment decisions in older cancer patients should account for patient age, comorbidities, local expertise and individual values.

Abstract
Introduction. In the UK, patients where liver resection is contemplated are discussed at hepatobiliary multidisciplinary team (MDT) meetings. The aim was to assess MDT performance by identification of patients where radiological and pathological diagnoses differed. Materials and Methods. A retrospective review of a prospectively maintained database of all cases undergoing liver resection from March 2006 to January 2012 was performed. The presumed diagnosis as a result of radiological investigation and MDT discussion is recorded at the time of surgery. Imaging was reviewed by specialist gastrointestinal radiologists, and resultswereagreedonby consensus. Results. Four hundred and thirty-eight patients were studied. There was a significant increase in the use of preoperative imaging modalities (P ≤ 0.01) but no change in the rate of discrepant diagnosis over time. Forty-two individuals were identified whose final histological diagnosis was different to that following MDT discussion (9.6%). These included 30% of patients diagnosed preoperatively with hepatocellular carcinoma and 25% with cholangiocarcinoma of a major duct. Discussion. MDT assessment of patients preoperatively is accurate in terms of diagnosis. The highest rate of discrepancies occurred in patients with focal lesions without chronic liver disease or primary cancer, where hepatocellular carcinoma was overdiagnosed and peripheral cholangiocarcinoma underdiagnosed, where particular care should be taken. Additional care should be taken in these groups and preoperative multimodality imaging considered.

Abstract
INTRODUCTION Traditionally, rates of irresectable disease at laparotomy for colorectal liver metastases (CRLM) have ranged from 15 to 70%. Diagnostic laparoscopy has been shown to be effective at preventing nontherapeutic laparotomy in selected patients. The purpose of this study was to analyze the resectability rate and role of diagnostic laparoscopy in a contemporary cohort. METHODS Using a prospectively maintained database, we identified patients who were explored for presumed resectable CRLM. Clinical and pathologic data associated with the finding of irresectable disease were analyzed. RESULTS From 2008-2010, 455 patients were explored. Of these, 35 (7.7%) did not undergo a resection and/or ablation. Of the 35 patients with irresectable disease, 15 (43%) had disease limited to the liver, 17 (49%) had extrahepatic disease (EHD), and 3 (9%) had other reasons precluding resection. Of the whole cohort, 45 patients (9.9%) were found to have EHD, and 27 of these (60%) underwent complete resection or ablation. The only factor associated with irresectable disease was a prior history of EHD, which was present in 29% of those found irresectable versus 13% of those resected (p = 0.022). Diagnostic laparoscopy was performed in 55 patients. Four of these patients had irresectable disease, and three were spared unnecessary laparotomy. Therefore, the yield was 5% and the sensitivity 75%. CONCLUSIONS The finding of irresectable disease is a rare event with modern radiologic assessment and the expansion of indications for resection. Diagnostic laparoscopy has a low yield and should be considered if there is a history of EHD or suspicious findings on preoperative imaging.

Abstract
PURPOSE The aim of this study was to evaluate factors affecting the difficulty of laparoscopic total mesorectal excision (L-TME), focusing on the pelvic anatomy. METHODS Seventy-four patients who underwent L-TME were prospectively enrolled. Tumor and patient factors, including magnetic resonance imaging-based pelvic measurements (obstetric conjugate, sacral length, sacral depth, interspinous distance, and intertuberous distance), were analyzed with respect to pelvic dissection time. Variable significantly correlated with pelvic dissection time in linear regression were considered risk factors which we defined as lower or upper quartile of each significant variable. Patients were categorized into 3 groups: easy group, no risk factors; moderate group, 1 to 2 risk factors; and difficult group, ≥ 3 risk factors. RESULTS Multivariate analysis showed that long sacral length, shallow sacral angle, narrow intertuberous diameter, and large tumor size were significantly associated with longer pelvic dissection time (P=0.018, P<0.001, P=0.034, P=0.032, respectively). The cutoff values of the upper quartile were 11.5 cm and 4.5 cm for sacral length and tumor size, and cutoff values of the lower quartile were 3.0 cm and 8.9 cm for sacral depth and intertuberous diameter. Logistic regression analysis showed that difficult group significantly contributed to intraoperative complication (95% confidence interval: 1.364-122.313, P=0.026) but not postoperative complication. CONCLUSIONS Having a narrow, deep pelvis and a large tumor were not found to adversely affect postoperative outcomes. However, in terms of operation time and intraoperative difficulty, anatomical factors should be taken into consideration when planning L-TME.

Abstract
BACKGROUND The role of staging laparoscopy (SL) with laparoscopic ultrasound (LUS) in patients with resectable colorectal liver metastases (CRLM) remains controversial. METHODS A meta-analysis of all studies (from 1998 to the present) on the effect of SL/LUS in patients with potentially resectable CRLM with respect to alteration in surgical management was performed. RESULTS Twelve studies satisfied the inclusion criteria. A total of 1,047 patients underwent SL/LUS. The true yield of SL/LUS for CRLM was 19% (95% confidence interval [CI], 16%-22%), with a diagnostic odds ratio of 132 (95% CI, 56-310) and an overall sensitivity of 59% (95% CI, 53%-65%). Subgroup analysis for detection of other liver and peritoneal lesions showed a sensitivity of 59% (95% CI, 49%-67%) and 75% (95% CI, 63%-85%) respectively. There was major between-study heterogeneity for all analyses, with no obvious cause revealed by meta-regression. CONCLUSIONS The true benefit of using SL/LUS universally seems limited. It appears more useful as an adjunct in patients when peritoneal disease is suspected.

Abstract
Fifty percent of patients with colorectal cancer will develop metastases at some time during their disease, with the liver being the most common site. Recent advances in the treatment of metastatic colorectal cancer have led to a change in treatment paradigm. What follows is a review of the surgical management of hepatic colorectal metastases responding to neoadjuvant chemotherapy. In addition, the complexity of treating patients with "disappearing" colorectal liver metastases is discussed.

Abstract
Aggressive treatment, including resection of both metastasis and primary tumor, has been studied for non-small cell lung cancer patients with synchronous solitary brain metastasis. Involvement of mediastinal lymph nodes is considered a poor prognostic factor and a contraindication to surgical resection of the primary lung tumor after treatment for brain metastasis. Here we present the case of a patient who presented with a Stage IV T1N2M1 non-small cell lung cancer with synchronous solitary brain metastasis. He is alive and without evidence of disease two years after aggressive, multimodality treatment that included craniotomy, whole-brain radiation therapy, thoracic surgery, chemotherapy, and mediastinal radiation therapy.

Abstract
Metastasectomy with curative intent has become standard practice for the management of some malignancies. Resection of isolated metastatic colorectal cancer, gastrointestinal stromal tumours, neuroendocrine cancers, renal-cell cancer and sarcoma is associated with longer survival or even cure. The strongest evidence in favour of metastasectomy exists for colorectal cancer, in which resection of limited metastatic disease in some patients is associated with 5-year survival rates of more than 50%.(1-3) High incidence of the disease, predictable tumour biology, and development of successful chemotherapies have encouraged metastasectomy. Furthermore, improved safety of complex surgeries over the past several decades has lowered the threshold for more aggressive surgical intervention. Most literature on metastasectomy pertains to the resection of disease involving the liver, lung, and brain. However, metastasectomy has been described for almost every organ system, including the pancreas. In this Review, we discuss resection of isolated cancer metastases to the pancreas. Pancreatic metastasectomy is most often done through a formal pancreatic resection such as pancreaticoduodenectomy or distal pancreatectomy. Less often, pancreatic metastasectomy is done by enucleation or a pancreas sparing operation such as a central pancreatectomy.

Abstract
BACKGROUND Surgical resection of malignant hepatic tumors has been demonstrated to increase overall survival; however, the majority of patients are not candidates for resection. For patients with unresectable tumors, various chemical and thermal ablation modalities have been developed. microwave coagulation therapy (MCT) is one such thermal ablation modality and the purpose of this review is to evaluate the presently available data for MCT and assess the level of evidence to support its clinical use. METHODS This review is limited to published studies in the English literature including at least 30 patients per study with MCT for hepatocellular cancer (HCC) or colorectal hepatic metastasis (CRHM). Patterns of local recurrence, complications and survival outcome of MCT ablation are presented and discussed including assessment of Asian experience using the 2.4GHZ device and American experience using the 914MHZ device. CONCLUSIONS Although randomized controlled trials comparing RFA and MCT for hepatic ablation are lacking, our review (based on level 2 data) supports that MCT may be optimal when larger necrosis zones and/or ablation of multiple lesions are the objectives. The data support that the potential procedural advantage(s) noted for ablation of CRHM and HCC >3cm, is not supported for HCC <3cm; moreover MCT shares with all other ablation modalities a high rate of locoregional recurrence in HCC; likely due to the multicentricity of this disease process.

[PMID: 19020939 DOI: 10.1245/s10434-008-0230-6] [Citation(s) in RCA: 28] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/22/2008] [Revised: 10/06/2008] [Accepted: 10/08/2008] [Indexed: 11/18/2022]
Abstract
Surgery is the treatment of choice in selected patients with hepatic colorectal metastases. Despite improvements in preoperative imaging, patients can undergo unnecessary nontherapeutic laparotomy. The aim of this study was to examine trends in nontherapeutic laparotomy rates in patients undergoing planned surgical therapy for hepatic colorectal metastases. Data from 530 operations (461 patients) undergoing potentially curative surgical therapy for colorectal liver metastases between 1994 and 2005 were analyzed. The incidence of nontherapeutic laparotomy was determined and factors associated with nontherapeutic laparotomy were identified. Overall, 49 nontherapeutic laparotomies were performed (9.2%). Higher nontherapeutic laparotomy rates were seen in patients with multiple metastases and tumor size >5 cm (both P < 0.05). Preoperative positron emission tomography (PET) imaging was associated with lower risk of nontherapeutic laparotomy [5.6% versus 12.4%, P = 0.009, odds ratio (OR) = 0.42]. At laparotomy, extrahepatic findings were the reason for nontherapeutic laparotomy in 44.9% of cases. The nontherapeutic laparotomy rate significantly decreased over time (14.9% for 1994-1997 versus 9.6% for 1998-2001 versus 4.7% for 2002-2005; P = 0.003). While patients in each time period were similar with regard to tumor specific factors, utilization of PET imaging (P < 0.001) as well as resection plus ablation (P = 0.004) increased over time. We conclude that prevalence of nontherapeutic laparotomy for patients undergoing surgical exploration for hepatic colorectal metastases has decreased significantly in recent years to less than 5%. The reasons for this trend are probably multifactorial and may include improved preoperative assessment, such as PET imaging, as well as salvage surgical options.

Abstract
Liver metastases are a common event in colorectal carcinoma. Significant advances have been made in managing these patients in the last decade, including improvements in staging and surgical techniques, an increasing armamentarium of chemotherapeutics and multiple local ablative techniques. While combination chemotherapy significantly improves median patient survival, surgical resection provides the only prospect of cure and is the focus of this review. Interpretation of published work in this field is challenging, particularly as there is no consensus to what is resectable disease. Of particular interest recently has been the use of neoadjuvant treatment for downstaging and downsizing disease in patients with initially unresectable liver metastases, in the hope of response leading to potentially curative surgery. This review summarizes the recent developments and consensus guidelines in the areas of staging, chemotherapy, local ablative techniques, radiation therapy and surgery, emphasizing the multidisciplinary approach to this disease and ongoing controversies in this field and examines the changing paradigms in the management of colorectal hepatic metastases.

Abstract
BACKGROUND Careful selection of patients with colorectal liver metastases for liver resection should minimize the risk of unnecessary laparotomy due to unresectable disease. The impact of staging laparoscopy with laparoscopic ultrasonography (LapUS) on clinical decision making in selected patients with potentially resectable colorectal liver metastases was evaluated. PATIENTS AND METHODS Staging laparoscopy with or without LapUS was performed in 77 of 415 consecutive patients (19%) with colorectal liver metastases deemed potentially resectable following liver-specific CT and/or MRI scanning. Retrospective analysis of prospectively collected data compared clinical outcomes with those in whom laparoscopy had been deferred in favour of laparotomy. RESULTS Staging laparoscopy was successful in 76 of 77 patients (99%). Adverse events occurred in three patients (4%): bowel injury n=2; late port site metastasis, n=1. Laparoscopic staging identified factors precluding curative resection in 16 patients (21%), thus averting unnecessary laparotomy. Of the 57 patients (74%) staged laparoscopically who underwent surgical exploration, 7 patients (12%) were unresectable and liver resection was achieved in 50 (88%). DISCUSSION Laparoscopic staging remains useful in detecting occult intra- and extra-hepatic tumour in selected patients with potentially operable colorectal liver metastases.

Abstract
PURPOSE New chemotherapy agents and integrated treatments have improved the prognosis of patients with metastatic colorectal cancer. METHODS From January 2000 to December 2002, 229 consecutive metastatic patients were prospectively followed and their outcomes were analyzed. They were divided initially into four treatment groups: A, palliative chemotherapy for extensive extrahepatic disease with or without hepatic disease (97 patients); B, palliative chemotherapy as in Group A for extensive hepatic disease unlikely to become resectable (36 patients); C, neoadjuvant chemotherapy for potentially resectable liver metastases if responsive to therapy (33 patients); D, immediate surgery for liver metastases (63 patients). RESULTS The series was analyzed after a median follow-up of 22.6 months. The median progression-free survival was 9, 7.3, 11.5, and 26 months in Groups A, B, C, and D, respectively. The median overall survival was 20.1, 17.2, 24.8, and >48 months in Groups A, B, C, and D, respectively. The outcome was considered for the 69 patients with metastases confined to the liver (Groups B and C), who were treated initially with chemotherapy. Surgery was performed in 21 patients (5 from Group B, and 16 from Group C) and was R0 in 16. In resected patients, the median progression-free survival was 14.7 months and the median overall survival was 40.5 months. In unresected patients, the median progression-free survival was 7.6 months and the median overall survival was 17.5 months. CONCLUSIONS Neoadjuvant therapy may prolong overall survival in a subset of patients with multiple hepatic metastases. The global impact on progression-free survival is low; less than one-half of the patients resected after chemotherapy are disease-free at three years. However, patients resected after chemotherapy obtained overall survival similar to that of primary surgery, suggesting a positive role for integrated approaches.

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 role of systemic chemotherapy in the management of colorectal cancer has been re-evaluated with the advent of newer agents. The results of published trials are reviewed in this article and the protocols of some of the major ongoing trials outlined. METHODS A medline based literature search was performed for articles relating to clinical trials using systemic chemotherapy in the management of colorectal cancer in the advanced and adjuvant setting. Additional original papers were obtained from citations in those identified by the initial search. RESULTS The combination of irinotecan or oxaliplatin with 5-fluorouracil (5-FU) based chemotherapy regimens for advanced cancer demonstrates better response rates when compared with 5-FU and folinic acid (FA). Although this translates into a modest survival benefit, it may increase resectability rates in patients with hepatic metastasis. Adjuvant chemotherapy in stage III cancer has been established to improve long-term survival although it is benefit for patients with stage II disease remains less clear. CONCLUSION Evaluation of the various combinations of chemotherapeutic agents that are most effective and the clinical situations for which they are best suited is ongoing and will improve the current outlook for those with colorectal cancer.

Abstract
Abstract
Background
The aim of this study was to assess the additional value of information provided by positron emission tomography (PET) with [18F]fluoro-2-deoxy-d-glucose (FDG) over that provided by computed tomography (CT) in patients with resectable liver metastases from colorectal cancer.
Methods
Between October 2001 and November 2002, a prospective double-blind comparison of preoperative FDG-PET and thoracoabdominal CT was performed in 53 patients with potentially resectable liver metastases from colorectal cancer. All resected metastases were subjected to histological examination.
Results
Histological examination confirmed the presence of malignant or benign lesions detected by PET and/or CT in 95 per cent of instances. Overall sensitivity (78 per cent) and accuracy (88 per cent) of PET were equivalent to those of CT (76 and 86 per cent respectively). The sensitivity of PET was equivalent to that of CT for hepatic sites (both 79 per cent), but was superior for extrahepatic abdominal sites (63 and 25 per cent respectively). PET provided additional information in five patients, mainly by revealing abdominal extrahepatic metastases, but falsely upstaged three patients.
Conclusion
Whole-body FDG-PET may identify unrecognized extrahepatic metastases in patients with potentially resectable liver metastases imaged by CT. However, additional information provided by PET is not as reliable as suggested by earlier retrospective studies.

Abstract
OBJECTIVES In asymptomatic patients presenting with non-resectable synchronous metastatic disease from colorectal adenocarcinoma, the beneficial effect of resecting the primary tumor remains to be documented. The aim of this study was to compare survival of patients with metastatic colorectal cancer who underwent elective resection of the primary tumor to those who did not. METHODS A retrospective analysis of patients with metastatic colo-rectal cancer treated between June, 1996 and December, 1999 was performed. Overall survival was compared between patients who underwent first-line resection of the primary colorectal tumor (group 1) or those who did not undergo elective resection of the primary (group 2). The probability of surgical resection of the primary tumor for gastrointestinal complications in group 2 was evaluated. RESULTS Thirty-one and 23 patients were included in groups 1 and 2 respectively. Five patients (21.7%, 95% confidence interval CI95% 4.9-38.5%) in group 2 required surgical treatment for intestinal obstruction due to the primary tumor. Two clinical characteristics were significantly different between groups 1 and 2: rectal localization (9.7% versus 34.7%; P=0.03) and presence of fewer than three metastases (29.0% versus 4.3%; P=0.03). Survival curves were not significantly different (logrank). Median duration of survival was 21 and 14 Months, respectively (P=0.718). CONCLUSION In patients with non-resectable synchronous metastatic disease, non-surgical management of the primary tumor is a rational alternative if asymptomatic. A prospective randomized trial integrating the quality-of-life factor should be organized.

Abstract
BACKGROUND Patients chosen for liver resection of colorectal liver metastases are a select group with minimal disease, favorable tumor biology and earlier presentation when compared to unresectable patients. Despite intense preoperative assessments, operative detection of occult unresectable disease is inevitable for a small group of patients. The aim of this study was to evaluate determinants of occult unresectability, and to establish if patients with occult unresectable disease demonstrate survival benefits similar to resected patients, or more similar to patients diagnosed with metastatic disease who were never explored. METHODS A retrospective medical record review was performed on 171 patients with colorectal hepatic metastases who underwent exploration with the intent of performing a curative liver resection. Patient and tumor characteristics, operative findings and survival were evaluated. Univariate and multivariate analysis were performed to evaluate determinants of unresectability, and survival was determined by Kaplan-Meier analysis. RESULTS One hundred forty-six patients were completely resected and 25 patients were found to have occult unresectable disease during exploration. Of these 25 patients, 10 had more extensive hepatic disease than expected which precluded resection, while 15 patients had unexpected extrahepatic disease. Of the 15 patients with extrahepatic disease, 7 had otherwise resectable liver metastases. Only bilobar disease was a statistically significant finding associated with occult unresectability on multivariate analysis (P = 0.05). Resected patients had a median survival of 37 months, while unresected patients had a median survival of 17 months (P < 0.005). At 3 and 5 years, the overall survival for resected patients was 52% and 29%. The survival at 3 years for patients with occult unresectable disease was only 5%, with no 5 year survivors. CONCLUSIONS The majority of patients with occult unresectable colorectal hepatic metastases had bilobar disease or extrahepatic spread. Despite the process of patient selection that leads to an attempt for curative resection, patients with occult unresectable disease identified at exploration suffer from poor survival that approximates the outcome of patients never considered for resection.

Abstract
BACKGROUND This investigation was undertaken to define the value of laparoscopy in the staging of patients with colorectal carcinoma metastatic to the liver. METHODS The clinical details of 59 consecutive patients with colorectal liver metastases undergoing laparoscopy prior to planned hepatectomy were entered prospectively on a computerized database. All patients were staged preoperatively with thin slice (5-7 mm) helical computed tomography chest, abdomen and pelvis. Synchronous metastases were defined as those found during, or on imaging carried out within 1 month of, colorectal resection. Criteria for laparoscopic unresectability were: (i) histologically proven extrahepatic disease; (ii) bilateral inflow or outflow involvement; (iii) the presence of cirrhosis in patients requiring an extended resection (lobectomy or greater); or (iv) hepatic metastases involving more than six hepatic segments. RESULTS In 24 patients with synchronous metastases (median age 65 years, range 32-81 years) all were resectable on laparoscopic criteria, of whom 21 were resected. Extrahepatic disease was found at laparotomy in three patients. In 35 patients with metachronous metastases (median age 64 years, range 32-81 years) laparoscopy could not be performed in five patients because of adhesions, and three patients were deemed unresectable on laparoscopic criteria. Of the remaining 27 patients, 25 underwent resection while two proved unresectable. Overall eight of 54 evaluable patients had unresectable disease and laparoscopy correctly identified three patients. CONCLUSIONS Following computed tomography scan, 15% of patients with metastatic colorectal carcinoma will be found to have unresectable disease. Laparoscopy will identify approximately half. Laparoscopy is of no greater value in staging synchronous versus metachronous metastases.

Abstract
Radiofrequency interstitial tissue ablation is a local ablative therapy in which tumors are destroyed in situ by thermal coagulation and protein denaturation through frictional heating produced by tissue ionic agitation from high-frequency alternating current. This technology can be used to destroy primary and metastatic hepatic lesions generally considered nonresectable or nonoperable, thus providing patients with these tumors, who have few treatment options, a relatively safe and effective alternative with the potential for improved chance of survival. Knowledge of the broad spectrum of potential complications associated with radiofrequency ablation (RFA) is essential for prevention, early detection, and proper management. Combining RFA with other modalities such as surgical resection or hepatic artery infusional chemotherapy is feasible, has increased the pool of operable patients, and may improve treatment efficacy and clinical outcome in properly selected patients. The approach to perform RFA percutaneously, laparoscopically, or during laparatomy should take into consideration tumor characteristics, imaging and technical limitations, and the role of other treatment modalities. Therefore, patients considered for RFA should be evaluated within the context of a multidisciplinary approach to insure proper patient selection and coordination of adjunct therapy.

Abstract
The prime role of hepatic resection in the management of colorectal cancer metastatic to the liver is firmly established. At least a third of patients who undergo liver resection for colorectal metastases can expect to survive five years. Since 1999, 106 hepatic metastases were resected in 42 patients (synchr. 8, metachr. 34, pts.). We performed 12 monosegmentectomies (S2-S8), 4 bisegmentectomies (S4b, S5 and S5, S6), 6 sectorectomies (right posterior, left paramedian, left lateral), 3 polysegmentectomies (S4b, S5, S6), 8 bilateral sectionectomies (S2, S3 and S6, S7) and in 9 cases multiple segmentectomies. In 4 cases initially unresectable colorectal metastases were downstaged by transcatheter HAI regional chemotherapy (Implantoflx), and after that successfully resected. We favour vascular inflow occlusion through selective division of appropriate portal pedicle at the porta hepatis or by transparenchymal approach. Median blood loss was 330 +/- 160 ml. The complication rate amounted to 9.52% (bile fistula, abscess collection). No method related lethality occurred. During the follow-up period we registered tumor recurrence rate of 19.1% (8 pts.), of which two patients were subjected to liver re-resection. Overall 3-year survival rate (Kaplan-Meier) is 38.9%. Multivariate analysis shows a significant correlation between 3-year survival and solitary (p-0.031) and unilobar metastases (p-0.014).

Abstract
BACKGROUND Resection of colorectal liver metastases infiltrating the inferior vena cava (IVC) or hepatic venous confluence (HVC) is technically feasible, but the procedure frequently involves invasive techniques, and its long-term outcome has not yet been fully described. STUDY DESIGN From October 1994 through June 2001, 87 patients underwent first curative hepatic resections for colorectal metastases. Nine patients (the IVC/HVC group) received hepatectomy combined with IVC or HVC reconstruction. Clinicopathologic characteristics, surgical results, and patient survival were investigated and compared with those of the remaining 78 patients (the comparison group). RESULTS Three IVCs and eight hepatic veins were successfully resected and reconstructed by primary closure (n = 3), direct anastomosis (n = 1), or by the use of autologous vein grafts (n = 7). A comparison between the two groups revealed that the primary colorectal tumor stage was similar, but the IVC/HVC group had more (median 4 versus 2, p < 0.05) and larger (median 5.0 versus 3.2 cm, p < 0.05) lesions. The IVC/HVC group required longer operating times (median 600 versus 320 minutes, p < 0.001) and suffered greater blood loss (median 1,034 versus 434 g, p < 0.01) and more extensive liver parenchyma resection (median 585 versus 155 g, p < 0.001). Patients in the IVC/HVC group had a shorter survival time (median survival time 25.8 versus 44.0 months, p < 0.01). CONCLUSIONS Hepatic resection combined with the IVC or HVC reconstruction for colorectal liver metastases can be performed with acceptable morbidity, and possibly with no mortality. Although no definite conclusion on long-term survival can be drawn from our study, given the limited number of patients, their overall survival was unsatisfactory. Further studies are needed to clarify the contribution of combined resection and reconstruction of IVC/HVC to long-term survival, because surgical resection currently provides the only hope of cure.

Abstract
BACKGROUND Laparoscopic staging (LS) of upper gastrointestinal malignancy has decreased the number of non-curative laparotomies. However, as radiological techniques have improved the value of this invasive staging technique has decreased, with some units either being more selective or abandoning it altogether for certain tumour types. The aim of the present study is to prospectively evaluate the additional utility of LS of upper gastrointestinal malignancy after radiological staging with modern techniques. METHODS One hundred and six consecutive patients assessed as having potentially curable upper gastrointestinal malignancy after radiological staging underwent LS between April 1999 and June 2001. Laparoscopic findings, outcome at laparotomy and complications were prospectively recorded. RESULTS Laparoscopic staging detected incurable disease in 28 of the 106 patients (26%). The negative likelihood ratio was 0.36 (95% CI 0.24-0.53). Twenty-seven patients were considered incurable because of findings at laparoscopy and one on the findings of laparoscopic ultrasound. Ten patients underwent open palliative procedures and seven had non-therapeutic laparotomies giving a non-curative laparotomy rate of 16%. LS was most useful for primary liver and biliary tract tumours and was least useful for colorectal liver metastases. The most frequent findings denoting incurability were the presence of liver disease (12 cases) and peritoneal metastases (nine cases). Complications occurred in three patients with one death being attributable in part to the laparoscopy. CONCLUSIONS Laparoscopy was useful in decreasing the number of non-therapeutic laparotomies, but laparoscopic ultrasound gave little additional benefit. The utility of LS was dependent on tumour type and in particular was of marginal benefit for colorectal liver metastases. LS remains a useful staging tool but should be applied selectively.

Abstract
BACKGROUND AND OBJECTIVES To assess the value of FDG positron emission tomography (PET) for early detection of incomplete tumor destruction after radiofrequency ablation (RFA) for liver metastasis. METHODS Twenty-eight unresectable liver metastases in 17 patients were treated by RFA. Patients underwent computed tomography (CT) and FDG-PET preoperatively, at 1 week, 1 month, and 3 months postoperatively. Postoperative CT and FDG-PET at 1 week and 1 month were analyzed to identify hypervascular and hypermetabolic residual tumors at the RFA site. These results were correlated with follow-up CT and, in case of reintervention, with pathologic results. RESULTS In 24/28 of RFA-treated metastases, CT and FDG-PET at 1 week and 1 month showed no tumor residues. During follow-up, none of these 13 patients developed local recurrence at RFA site. In four patients, FDG-PET at 1 week and 1 month showed peripheral hypermetabolic residue after RFA, whereas CT did not revealed residual tumor. In three patients, local persistence of viable tumor cells was biopsy-proven at reintervention. In the fourth, follow-up CT showed subsequent development of a local recurrence. CONCLUSIONS FDG-PET accurately monitors the local efficacy of RFA for treatment of liver metastases, as it early recognizes incomplete tumor ablation, not detectable on CT.

Abstract
OBJETIVO: Determinar o impacto de fatores prognósticos na sobrevida de pacientes com metástases hepáticas ressecadas e originadas de câncer colorretal. CASUÍSTICA E MÉTODOS: Foram analisados os prontuários de 28 pacientes submetidos a ressecção hepática de metástases de câncer colorretal de abril de 1992 a setembro de 2001. Foram realizadas 38 ressecções (8 pacientes com mais de uma ressecção no mesmo tempo cirúrgico e 2 pacientes submetidos a re-ressecções). Todos haviam sido submetidos previamente a ressecção do tumor primário. Utilizou-se protocolo de rastreamento de metástases hepáticas que incluiu revisões clínicas trimestrais, ecografia abdominal e dosagem de CEA até se completarem 5 anos de seguimento e após, semestralmente. Os fatores prognósticos estudados foram: estágio do tumor primário, tamanho das metástases > 5cm, intervalo entre ressecção do tumor primário e surgimento da metástase < 1 ano, CEA >100 ng/mL, margens cirúrgicas < 1cm e doença metastática extra-hepática. O estudo foi retrospectivo e a análise estatística foi feita pela curva de Kaplan-Meier, log-rank e regressão de Cox. RESULTADOS: A morbidade foi 39,3% e a mortalidade operatória foi 3,6%. A sobrevida em 5 anos foi de 35%. Os fatores prognósticos independentes adversos foram: intervalo < 1 ano entre ressecção do tumor primário e surgimento da metástase, e doença metastática extra-hepática. CONCLUSÕES: A ressecção hepática de metástases de câncer colorretal é um procedimento seguro com sobrevida em 5 anos acima dos 30%. Foram fatores prognósticos independentes adversos: doença metastática extra-hepática e intervalo < 1 ano entre ressecção do tumor primário e surgimento da metástase.

Abstract
PURPOSE To evaluate whether preoperative portal vein embolization (PVE) with polyvinyl alcohol (PVA) particles and coils is safe and effective for inducing lobar hypertrophy in patients with hepatobiliary malignancy. MATERIALS AND METHODS PVE was performed in 26 patients. All patients had malignancy: metastases (n = 11), cholangiocarcinoma (n = 9), hepatocellular carcinoma (n = 5), and gallbladder carcinoma (n = 1). One patient had underlying liver disease caused by hepatitis. PVE was performed if the future liver remnant (FLR) was estimated to be less than 25% of the total liver volume. PVE was performed with a percutaneous transhepatic approach (right, 25 patients; left, one patient). PVA particles and coils were used to occlude the right portal system and veins supplying segment IV to promote FLR hypertrophy (segments I-III +/- IV). FLR hypertrophy was assessed with comparison of computed tomographic scans obtained before and 2-4 weeks after PVE. Effectiveness evaluation was based on changes in absolute FLR size and ratio of FLR to total estimated liver volume (TELV). Safety of PVE and hepatic resection was determined with postprocedure complication rate and median hospital stay. RESULTS Sixteen patients underwent hepatic resection (right trisegmentectomy [n = 13], right lobectomy [n = 3]) without mortality. Ten patients did not undergo resection (complete remission after medical therapy [n = 1], lack of regeneration [n = 2], extrahepatic disease undetected prior to PVE [n = 7]). Six patients had biliary obstruction; five were treated percutaneously before PVE. No patient developed postembolization syndrome or signs of fulminant hepatic insufficiency after PVE or resection. Two patients had complications after PVE that did not preclude successful resection. Median hospital stays were 1 day (PVE) and 7 days (liver resection). Mean absolute FLR increased from 325.0 to 458.6 cm3 (increase, 41.1%). Mean TELV was 1,784.8 cm3. FLR/TELV ratio increase was 8%. CONCLUSION Preoperative PVE with PVA particles and coils is safe and effective for inducing lobar hypertrophy in patients with advanced hepatobiliary malignancy.

Abstract
Colorectal cancer is the second leading cause of mortality from cancer in the United States. Death from colorectal cancer usually results from metastatic disease to the liver. Complete surgical resection is the only potentially curative treatment option for metastatic colorectal cancer to the liver, with a five-year survival rate of approximately 30%-40%. The addition of adjuvant systemic or hepatic intra-arterial pump chemotherapy appears to improve survival. Treatment options for unresectable disease in the liver are cryosurgery (intraoperative freezing of tumors), radiofrequency ablation (intraoperative or percutaneous heating of tumors), hepatic intra-arterial infusion pump chemotherapy (regional chemotherapy), and systemic chemotherapy. This article describes metastatic colorectal cancer disease presentation, extent of disease evaluation, and nonchemotherapeutic treatment options, including surgical and ablative therapies. The nurse's role in caring for this population also will be discussed.

Abstract
BACKGROUND The aim was to assess the value of laparoscopy and laparoscopic ultrasonography (LUS) in selecting patients for resection of colorectal hepatic metastases. METHODS Sixty patients with potentially resectable colorectal hepatic metastases after helical computer tomography (CT) and scheduled to undergo laparoscopy and LUS were studied retrospectively. Primary outcome measurement was the number of cases in which laparoscopy and LUS resulted in a change of therapeutic approach. RESULTS Of the 60 patients, 59 patients were examined by LUS and/or laparoscopy. The small intestine was perforated due to adhesions in two patients, necessitating open exploration in one of them. In 17 patients (29%) the combined laparoscopic procedure yielded results prohibiting resection; another 6 patients were denied resection on other grounds. Of the 36 patients who underwent open exploration, 31 underwent resection. Combined laparoscopy and LUS predicted resectability correctly in 86% of the patient group. Compared with resection, the sensitivity of both CT and LUS to detect lesions was 91%. DISCUSSION Laparoscopy and LUS can avoid open exploration without resection in a substantial number of patients considered eligible for resection of colorectal hepatic metastases based on CT. LUS does not seem to detect more metastases than CT.

Abstract
PURPOSE The authors' goal was to determine the sensitivity and specificity of F-18 fluorodeoxyglucose (FDG) positron emission tomography (PET) for identifying patients with hepatic metastases from colorectal cancer and the accuracy of PET for determining the number and distribution of lesions within the liver. Intraoperative sonography and surgical inspection and palpation were used as the reference standard. METHODS Twenty-three patients being evaluated for surgical resection of hepatic metastases from colorectal carcinoma underwent FDG PET before operation. Findings of the PET studies were reviewed in a blinded, retrospective manner, with the results compared with the findings of intraoperative sonography and surgical exploration. Lesions of all sizes were considered in the analysis. RESULTS The FDG-PET results were positive in 21 of the 22 patients ultimately found to have metastatic disease to the liver, and they were negative in the single patient without metastases. Therefore, for identification of patients with hepatic metastatic disease, PET has a sensitivity of 95% and a specificity of 100%. In all, 48 metastatic lesions were identified in these patients, of which 38 (79%) were identified on PET images. The probability of lesion detection by PET was directly correlated with lesion size (P < 0.01). The assessment of lobar disease distribution in the liver was discordant between PET and surgery in 3 of 23 (13%) patients. CONCLUSIONS In patients being evaluated for potential curative resection of hepatic metastases from colorectal cancer, FDG PET is accurate for the identification of the presence or absence of metastatic disease to the liver. However, detection of individual lesions depends on their size, and determination of lesion number and distribution within the liver is more accurately accomplished with intraoperative sonography.
