Abstract
Management of metastatic colorectal cancer requires accurate staging and multidisciplinary evaluation, leading to a consensus treatment plan with the ultimate goal of increasing survival and improving the quality of life, while taking into consideration the patient's performance status, disease burden, and goals of care. Since the introduction of multidrug chemotherapeutic regimens, survival of patients with metastatic colorectal cancer has improved. Many patients with unresectable disease are undergoing surgery for asymptomatic primary tumors despite evidence that it is usually a futile intervention. Palliative measures for local control of the primary tumor include colonic stents, laser therapy, and fulguration.

Simultaneous Resection for Synchronous Colorectal Liver Metastasis: the New Standard of Care? J Gastrointest Surg 2017; 21:975-982.

Abstract
BACKGROUND Optimal surgical management for patients with synchronous colorectal cancer liver metastasis is controversial. We provide an analysis of surgical utilization and outcomes for patients presenting with synchronous colon and rectal cancer liver metastasis between simultaneous and staged approaches. METHODS SPARCS database was used to follow patients undergoing surgery for colorectal cancer with liver metastases from 2005 to 2014. Using International Classification of Diseases, Ninth Revision codes, we identified patients undergoing staged and simultaneous resection. Our primary endpoint was major events at 30-day follow-up. RESULTS Of the patients, 1430 underwent surgery for synchronous colorectal primary and liver metastases between 2005 and 2014. There was no difference in adjusted rates of major events or anastomotic leak. Patients undergoing simultaneous resection were significantly less likely to experience prolonged length of stay (OR = 0.28; 95% CI = 0.21-0.37) or high hospital charges (OR = 0.24; 95% CI = 0.17-0.32) compared to staged resection even among patients undergoing total hepatic lobectomy and complex colorectal resection. CONCLUSIONS Simultaneous resection was found to be equally as safe as staged resection even when evaluating patients undergoing more complex operations, and led to lower health care utilization. Under appropriate clinical circumstances, simultaneous resection offers benefits to patients and the health care system and should be the recommended surgical approach.

Abstract
BACKGROUND Simultaneous resection of primary colorectal cancer (CRC) and synchronous liver metastases (LM) is gaining interest. We describe management and outcomes of patients undergoing simultaneous resection in the general population. METHODS All patients with CRC who underwent surgical resection of LM between 2002 and 2009 were identified using the population-based Ontario Cancer Registry and linked electronic treatment records. Synchronous disease was defined as having resection of CRCLM within 12 weeks of surgery for the primary tumour. RESULTS During the study period, 1310 patients underwent resection of CRCLM. Of these, 226 (17%) patients had synchronous disease; 100 (44%) had a simultaneous resection and 126 (56%) had a staged resection. For the simultaneous and the staged groups, the mean number of liver lesions resected was 1.6 and 2.3, respectively (p < 0.001); the mean size of the largest lesion was 3.1 and 4.8 cm, respectively (p < 0.001); and the major hepatic resection rate was 21% and 79%, respectively (p < 0.001). Postoperative mortality for simultaneous cases at 90 days was less than 5%. Five-year overall survival and cancer-specific survival for patients with simultaneous resection was 36% (95% confidence interval [CI] 26%-45%) and 37% (95% CI 25%-50%), respectively. Simultaneous resections are common in the general population. A more conservative approach is being adopted for simultaneous resections by limiting the extent of liver resection. Postoperative mortality and long-term survival in this patient population is similar to that reported in other contemporary series. CONCLUSION Compared with a staged approach, patients undergoing simultaneous resections had fewer and smaller liver metastases and underwent less aggressive resections. One-third of these patients achieved long-term survival.

Abstract
One-stage curative surgical resection for obstructive colon cancer is challenging. Self-expandable metallic stents (SEMSs) are known as an alternative treatment used to avoid emergency operation. We aimed to evaluate the significance of SEMS placement as a bridge to surgery and the surgical outcomes of the elective operation. A consecutive 20 patients with obstructive colon cancer undergoing SEMS placement between June 2014 and February 2016 were included. The technical outcomes of the SEMS placement, surgical procedures, and surgical outcomes were evaluated retrospectively. Among them, 2 patients were treated with a SEMS palliatively, and the others were treated with a SEMS as a bridge to surgery. All SEMS were placed successfully at the first attempt, and there was no SEMS-related complication. Before surgery, all patients could be diagnosed histologically, and they were evaluated systemically including proximal colon or distant metastasis. The median time to operation after SEMS placement was 14 days (range 9–20 days). Seven of the 18 patients underwent a laparoscopic colectomy without conversion to laparotomy. All patients with stage II or III colon cancer underwent curative surgery, and 2 patients with stage IV colon cancer underwent a one-stage resection of the primary colon cancer and simultaneous liver metastasis after the evaluation of hepatic functional reserve. There was no mortality or SEMS-related complication in the perioperative period. SEMS placement as a bridge to surgery for patients with obstructive colon cancer is safe and effective to provide an adequate amount of time for a preoperative systemic management and evaluation.

Abstract
There is discrepancy and failure to adhere to current international guidelines for the management of metastatic colorectal cancer (CRC) in hospitals in Greece and Cyprus. The aim of the present document is to provide a consensus on the multidisciplinary management of metastastic CRC, considering both special characteristics of our Healthcare System and international guidelines. Following discussion and online communication among the members of an executive team chosen by the Hellenic Society of Medical Oncology (HeSMO), a consensus for metastastic CRC disease was developed. Statements were subjected to the Delphi methodology on two voting rounds by invited multidisciplinary international experts on CRC. Statements reaching level of agreement by ≥80% were considered as having achieved large consensus, whereas statements reaching 60-80% moderate consensus. One hundred and nine statements were developed. Ninety experts voted for those statements. The median rate of abstain per statement was 18.5% (range: 0-54%). In the end of the process, all statements achieved a large consensus. The importance of centralization, care by a multidisciplinary team, adherence to guidelines, and personalization is emphasized. R0 resection is the only intervention that may offer substantial improvement in the oncological outcomes.

Abstract
BACKGROUND Twenty-five percent of patients with colorectal cancer present with simultaneous liver metastasis. Complete resection is the only potential curative treatment. Due to improvements in operative and perioperative management, simultaneous liver and colon resections are an accepted procedure at specialized centers for selected patients. Nevertheless, little is known about the long-term, oncologic results of simultaneous operative procedures compared with those of staged operations. METHODS Patients with colorectal cancer and simultaneous liver metastases presenting for complete resection at a tertiary cancer center were identified. Patients who received the primary colon resection at an outside institution were excluded from analysis. RESULTS Between 1984 and 2008, 429 patients underwent operative treatment for colorectal cancer with simultaneous liver metastasis. Of these, 320 (75%) had simultaneous resection and 109 had staged resection. There was no difference in the distribution of primary tumor locations between the 2 groups. Mean size of the hepatic metastases was significantly greater in the staged group (median 4 cm vs 2.5 cm; P < .01). Neither disease-free nor overall survival differed significantly between the 2 treatment strategies. The extent of the liver procedure (more than 3 segments) was identified as a risk factor for decreased disease-free and overall survival (both P < .01). CONCLUSION Simultaneous liver and colorectal resections for metastatic colorectal cancer are associated with similar long-term cancer outcome compared with staged procedures.

Abstract
OBJECTIVE To compare outcomes of laparoscopic versus open hepatic resection (OHR) exclusively for hepatocellular carcinoma in terms of morbidity and cost. BACKGROUND Laparoscopic hepatic resection (LHR) has become more prevalent with recent improvements in instrumentation and surgeon experience. METHODS A review of multicenter, prospectively collected hepatobiliary databases from three institutions was performed from 12/1990 to 12/2009. Prospective evaluation of all patients undergoing hepatectomy for hepatocellular cancer was performed. RESULTS A total of 354 patients who had resections for Hepatocellular carcinoma (HCC) were analyzed, 100 were performed laparoscopically. The two groups were similar in terms of demographics and comorbidities. Evaluation of outcomes showed significantly higher intraoperative estimated blood loss although postoperative transfusion rates were similar. The incidence of any complication (44 vs 44%, p = 0.23) and 90-day mortality (6 vs 6%, p = 0.8) were similar between the two groups, with a similar reoperation rate (4.0 vs. 2.4%; p = 0.9). Using Cox regression analysis, the laparoscopic approach had no effect on disease-free interval (OR 1.4, CI 0.31-6.3, p = 0.66) or overall survival (HR 1.2, CI 0.59-2.5 p = 0.6). Length of stay was significantly shorter in the laparoscopic group 6.2 vs. 9.3 days (p = 0.001). Adjusted operative charges ($41 vs. $39 k, p = 0.601) and adjusted total hospital charges ($71 vs. $82 k, p = 0.368) were similar in LHR versus OHR. CONCLUSION Our study confirms previous literature showing comparable perioperative outcomes and recurrence. We further show comparable cost with laparoscopic versus open liver resection for HCC.

Abstract
INTRODUCTION Safety of synchronous hepatectomy and colorectal resection (CRR) for metastatic colorectal cancer remains controversial. We hypothesized that both the extent of hepatectomy and CRR influences postoperative outcomes. METHODS Prospective 2005-2013 ACS-NSQIP data were retrospectively reviewed for mortality and major morbidity (MM) after (1) isolated hepatectomy, (2) isolated CRR, and (3) synchronous resection for colorectal cancer. Hepatectomy and CRR risk categories were created based on mortality and MM of respective isolated resections. The synchronous cohort was then stratified based on risk categories. Cumulative asynchronous mortality and MM were estimated compared to that observed in the synchronous cohort via unadjusted relative risk and risk difference. RESULTS There were 43,408 patients identified. Among isolated hepatectomy patients (N = 6,661), trisectionectomy and right hepatectomy experienced the greatest mortality and were defined as "major" hepatectomy. Among isolated CRR patients (N = 35,825), diverted left colectomy, abdominoperineal resection, total abdominal colectomy, and total abdominal proctocolectomy experienced the greatest MM and were defined as "high risk" CRR. Synchronous patients (N = 922) were stratified by hepatectomy and CRR risk categories; mortality and MM varied from 0.9 to 5.0 % and 25.5 to 55.0 %, respectively. Mortality and MM were greatest for patients undergoing "high risk" CRR and "major" hepatectomy and lowest for synchronous CRR and "minor" hepatectomy. As both CRR and hepatectomy risk categories increased, there was a significant trend in increasing mortality and MM in synchronous patients. Additionally, comparison of the synchronous resections versus the estimated cumulative asynchronous outcomes showed that (1) mortality was significantly less after synchronous minor hepatectomy and either low or high risk CRR, and (2) neither mortality nor major morbidity differed significantly after major hepatectomy with either high or low risk CRR. CONCLUSION Major morbidity after synchronous hepatic and colorectal resections vary incrementally and are related to both the risk of hepatectomy and CRR. Stratification of outcomes by the hepatectomy and CRR components may reflect a more accurate description of risks. Comparison of synchronous and combined outcomes of individual operations supports a potential benefit for synchronous resections with minor hepatectomy.

Abstract
Although simultaneous resection of primary colorectal cancer and synchronous liver metastases is reported to be safe and effective, the feasibility of a laparoscopic approach remains controversial. This study evaluated the safety, feasibility, and short-term outcomes of simultaneous laparoscopic surgery for primary colorectal cancer with synchronous liver metastases. From September 2008 to December 2013, 10 patients underwent simultaneous laparoscopic resection of primary colorectal cancer and synchronous liver metastases with curative intent at our institute. The median operative time was 452 minutes, and the median estimated blood loss was 245 mL. Median times to discharge from the hospital and adjuvant chemotherapy were 13.5 and 44 postoperative days, respectively. Negative resection margins were achieved in all cases, with no postoperative mortality or major morbidity. Simultaneous laparoscopic colectomy and hepatectomy for primary colorectal cancer with synchronous liver metastases appears feasible with low morbidity and favorable outcomes.

Abstract
PURPOSE The role of minimally invasive colorectal resection for patients undergoing a simultaneous resection for synchronous liver metastases had not been established. This study compared the short- and long-term outcomes between minimally invasive and open colorectal resection for patients undergoing simultaneous resection for liver metastases. METHODS This study reviewed 101 consecutive patients undergoing simultaneous colorectal resection and R0 resection of synchronous liver metastases between January 2008 and December 2012. In the study, 36 consecutive patients who underwent minimally invasive colorectal resection were matched with 36 patients who had an open approach by propensity scoring. The analyzed variables included patient and tumor characteristics and short-term and long-term outcomes. RESULTS After propensity score matching, the two groups had similar clinicopathologic variables. No patient undergoing the minimally invasive procedure experienced conversion to the open technique. No postoperative mortality occurred in either group. In the minimally invasive group, the estimated blood loss (P < 0.007), bowel function return time (P < 0.016), and postoperative hospital stay (P < 0.011) were significantly lower than those in the open group, although the operating time was significantly longer (P < 0.001). No significant differences in postoperative complications were observed between the groups. The two groups did not differ significantly in terms of the 5-year overall survival rate (51 vs. 55 %; P = 0.794) and disease-free survival rate (38 vs. 27 %; P = 0.860). CONCLUSION Minimally invasive colorectal resection with simultaneous resection of liver metastases has an outcome similar to open approach but some short-term advantages.

Abstract
Ideally, tumors that might cause morbidity and mortality should be treated, preferably early, with proven, convincing, and effective therapy to prevent tumor progression or recurrence, while maintaining a favorable risk-benefit profile for the individual patient. For patients with colorectal cancer (CRC), this diagnostic, prognostic, and therapeutic precision is currently impossible. Despite significant improvements in diagnostic procedures, a sizable number of patients with CRC have liver metastases either at presentation or will subsequently develop it. And in many parts of the world, most cancer-related deaths are still due to metastases that are resistant to conventional therapy. Metastases to the liver occur in more than 50% of patients with CRC and represent the major determinant of outcome following curative treatment of the primary tumor. Liver resection offers the best chance of cure for metastases confined to the liver. However, due to a paucity of randomized controlled trials, its timing is controversial and a hotly debated topic. This article reviews some of the main controversies surrounding the surgical management of colorectal cancer liver metastases (CRLM).

Abstract
BACKGROUND One quarter of colorectal cancer patients will present with liver metastasis at the time of diagnosis. Recent studies have shown that simultaneous resections are safe and feasible for stage IV colon cancer. Limited data are available for simultaneous surgery in stage IV rectal cancer patients. METHODS One hundred ninety-eight patients underwent surgical treatment for stage IV rectal cancer. In 145 (73%) patients, a simultaneous procedure was performed. Fifty-three (27%) patients underwent staged liver resection. A subpopulation of 69 (35%) patients underwent major liver resection (3 segments or more) and 30 (44%) patients with simultaneous surgery. RESULTS The demographics of the 2 groups were similar. Complication rates were comparable for simultaneous or staged resections, even in the group subjected to major liver resection. Total hospital stay was significantly shorter for the simultaneously resected patients (P < .01). CONCLUSIONS Simultaneous resection of rectal primaries and liver metastases is a safe procedure in carefully selected patients at high-volume institutions, even if major liver resections are required.

Intermittent clamping of the hepatic pedicle in simultaneous ultrasonography-guided liver resection and colorectal resection with intestinal anastomosis: is it safe? Int J Colorectal Dis 2014; 29:1517-25. [PMID: 25185843 DOI: 10.1007/s00384-014-2004-x] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Accepted: 08/22/2014] [Indexed: 02/07/2023]
Abstract
PURPOSE In patients with colorectal cancer (CRC) and synchronous colorectal liver metastases (CRLM) potentially candidates to combined liver (LR) and colorectal resection (CRR), the extent of LR and the need of hepatic pedicle clamping (HPC) in selected cases are considered risk factors for the outcome of the intestinal anastomosis. This study aimed to determine whether intermittent HPC is predictive of anastomotic leakage (AL) and has an adverse effect on the clinical outcome in patients undergoing combined restorative CRR and LR. METHODS One hundred six LR have been performed for CRLM in our unit from July 2005. Patients who received CRR with anastomosis and simultaneous intraoperative ultrasonography (IOUS)-guided LR/ablation for resectable CRLM were included in this study. CRR was performed first. Intermittent HPC was decided at the discretion of the liver surgeon. The perioperative outcome was evaluated according to occurrence of AL and overall postoperative morbidity and mortality. RESULTS Thirty-eight patients underwent simultaneous IOUS-guided LR/ablation and CRR with intestinal anastomosis; 19 underwent intermittent HPC (group ICHPY) while 19 did not (group ICHPN); the mean ± SD (range) duration of clamping in group ICHPY was 58.6 ± 32.2 (10.0-125.0) min. Postoperative results were similar between groups. One asymptomatic AL occurred in group ICHPY (5.2 %). Major postoperative complications were none in group ICHPY and one (5.2 %) in group ICHPN, respectively. One patient in group ICHPY died postoperatively (5.2 %). CONCLUSIONS This study suggests that intermittent HPC during LR is not predictive of AL and has no adverse effect on the overall clinical outcome in patients undergoing combined restorative colorectal surgery and hepatectomy for advanced CRC.

Abstract
Colorectal cancer (CRC) is a major health concern in the United States (US) with over 140,000 new cases diagnosed in 2012. The most common site for CRC metastases is the liver. Hepatic resection is the treatment of choice for colorectal liver metastases (CLM), with a 5-year survival rate ranging from 35% to 58%. Unfortunately, only about 20% of patients are eligible for resection. There are a number of options for extending resection to more advanced patients including systemic chemotherapy, portal vein embolization (PVE), two stage hepatectomy, ablation and hepatic artery infusion (HAI). There are few phase III trials comparing these treatment modalities, and choosing the right treatment is patient dependent. Treating hepatic metastases requires a multidisciplinary approach and knowledge of all treatment options as there continues to be advances in management of CLM. If a patient can undergo a treatment modality in order to increase their potential for future resection this should be the primary goal. If the patient is still deemed unresectable then treatments that lengthen disease-free and overall-survival should be pursued. These include chemotherapy, ablation, HAI, chemoembolization, radioembolization (RE) and stereotactic radiotherapy.

Abstract
Background It remains unclear which patients can benefit from simultaneous resection of synchronous colorectal liver metastases (SCRLMs). This study aimed to examine the prognostic value of patient- and tumor-related factors in predicting long-term outcomes of patients undergoing simultaneous resection of SCRLMs and to help patients select a suitable therapeutic regimen and proper surveillance. Methods Clinicopathological and outcome data of 154 consecutive SCRLM patients who underwent simultaneous resection between July 2003 and July 2013 were collected from our prospectively established SCRLM data and analyzed with univariate and multivariate methods, and the prognostic index (PI) was formulated based on the regression coefficients (β) of the Cox model. The patients were classified into high- and low-risk groups according to the PI value; the cut-off point was the third quartile. Results The 5-year overall survival rate was 46%, and the 5-year disease-free survival rate was 35%. Five factors were found to be independent predictors of poor overall survival (OS) by multivariate analysis: positive lymph node status, vascular invasion, BRAF mutation, the distribution of bilobar liver metastases (LMs) and non-R0 resection of LMs. Compared to low PI (≤5.978), high PI (>5.978) was highly predictive of shorter OS. Three factors were found to be independent predictors of poor disease-free survival (DFS) by multivariate analysis: tumor deposits, BRAF mutation and bilobar LM distribution. We also determined the PI for DFS. Compared to low PI (≤2.945), high PI (>2.945) was highly predictive of shorter DFS. Conclusions Simultaneous resection of SCRLM may lead to various long-term outcomes. Patients with low PI have longer OS and DFS, while those with high PI have shorter OS and DFS. Thus, patients with high PI may receive more aggressive treatment and intensive surveillance, This model needs further validation.

Abstract
AIM: To assess the efficacy and safety of simultaneous vs staged operation for synchronous colorectal liver metastases.
METHODS: The relevant studies published between March 2004 and March 2014 were searched, and meta-analysis was performed to evaluate operative time, postoperative complications rate, perioperative mortality, postoperative 1-, 3-, 5-year survival rates and related indicators.
RESULTS: A total of 16 non-randomized controlled studies were included in this analysis. Comparing simultaneous to staged resection, there were no significant differences in operative time (WMD = -49.81, 95%CI: -125.07-25.46, P = 0.19), postoperative complications rate (OR = 1.26, 95%CI: 0.84-1.88, P = 0.26), perioperative mortality (OR = 1.69, 95%CI: 0.82-3.52, P = 0.16), postoperative 1- (OR = 0.69, 95%CI: 0.46-1.04, P = 0.08), 3- (OR = 0.69, 95%CI: 0.46-1.04, P = 0.08) and 5-year survival rates (OR = 1.00, 95%CI: 0.74-1.36, P = 0.98).
CONCLUSION: Simultaneous and staged resections show no significant differences in either safety or efficacy. The patient's general condition, primary tumor, tumor position, and number of liver metastases should be comprehensively assessed to formulate individualized approach.

Timing of hepatectomy for resectable synchronous colorectal liver metastases: for whom simultaneous resection is more suitable--a meta-analysis. PLoS One 2014; 9:e104348.

Abstract
BACKGROUND The optimal timing of resection for synchronous colorectal liver metastases is still controversial. Retrospective cohort studies always had baseline imbalances in comparing simultaneous resection with staged strategy. Significantly more patients with mild conditions received simultaneous resections. Previous published meta-analyses based on these studies did not correct these biases, resulting in low reliability. Our meta-analysis was conducted to compensate for this deficiency and find candidates for each surgical strategy. METHODS A systemic search for major databases and relevant journals from January 2000 to April 2013 was performed. The primary outcomes were postoperative mortality, morbidity, overall survival and disease-free survival. Other outcomes such as number of patients need blood transfusion and length of hospital stay were also assessed. Baseline analyses were conducted to find and correct potential confounding factors. RESULTS 22 studies with a total of 4494 patients were finally included. After correction of baseline imbalance, simultaneous and staged resections were similar in postoperative mortality (RR = 1.14, P = 0.52), morbidity (RR = 1.02, P = 0.85), overall survival (HR = 0.96, P = 0.50) and disease-free survival (HR = 0.97, P = 0.87). Only in pulmonary complications, simultaneous resection took a significant advantage (RR = 0.23, P = 0.003). The number of liver metastases was the major factor interfering with selecting surgical strategies. With >3 metastases, simultaneous and staged strategies were almost the same in morbidity (49.4% vs. 50.9%). With ≤3 metastases, staged resection caused lower morbidity (13.8% vs. 17.2%), not statistically significant. CONCLUSIONS The number of liver metastases was the major confounding factor for postoperative morbidity, especially in staged resections. Without baseline imbalances, simultaneous took no statistical significant advantage in safety and efficacy. Considering the inherent limitations of this meta-analysis, the results should be interpret and applied prudently.

Abstract
The management of synchronous presentation of colorectal cancer and liver metastases has long been a topic of debate and discussion for surgeons due to the unique dilemma of balancing operative timing along with treatment strategy. Operative strategies for resection include staged resection with colon first approach, "reverse" staged resection with liver metastases resected first, and one-stage, or simultaneous, resection of both the primary tumor and liver metastases approach. These operative strategies can be further augmented with perioperative chemotherapy and other novel approaches that may improve resectability and patient survival. The decision on operative timing and approach, however, remains largely dependent on the surgeon's determination of disease resectability, patient fitness, and the need for neoadjuvant chemotherapy.

Abstract
PURPOSE Combined resection of primary colorectal cancer and synchronous hepatic metastases has been shown to be safe and associated with acceptable oncologic outcomes in selected patients. The purpose of this study was to determine if selection criteria for combined resection could be identified using major morbidity or mortality as an avoidable outcome. METHODS We queried the American College of Surgeons National Surgery Quality Improvement Program dataset from 2005 to 2010 for combined liver and colorectal resections for colorectal cancer using procedure and diagnosis codes. These patients were compared to colorectal cancer patients receiving colectomy alone and patients receiving liver-directed surgery for secondary liver cancer. RESULTS During the study period, 1,641 (53.1 %) of patients underwent colectomy alone, 1,113 (36 %) underwent liver-directed surgery alone, and 334 (10.9 %) underwent combined colectomy and liver-directed surgery for colorectal cancer. The combined patient population had statistically significant increases in American Society of Anesthesiologists class, preoperative ascites, preoperative systemic inflammatory response syndrome/sepsis, weight loss, functional dependence, and decreased serum albumin compared to the other cohorts. While major hepatectomy was less frequent in the combined cohort, the rate of rectal resection was similar to the colectomy-alone cohort. These selection disparities resulted in a subsequent increase in composite major morbidity, return to operating room, infectious complications, and length of stay in combined patients. CONCLUSIONS While combined resection in patients with synchronous colorectal cancer hepatic metastases may be feasible, it is associated with considerable increase in morbidity without application of stringent selection criteria. We recommend only patients without known risk factors for perioperative morbidity and infectious complications be considered for this approach.

Abstract
INTRODUCTION Simultaneous resection for colorectal cancer and synchronous colorectal liver metastases (SCRLM) has been found to be safe and effective. However, pure laparoscopic simultaneous resection (PULSAR) for primary colorectal cancer and SCRLM is usually difficult, especially in the right lobe of the liver. The purpose of this study was to assess the feasibility of PULSAR for patients with primary colorectal cancer and SCRLM. METHODS From January 2008 to December 2012, a total of 10 patients (9 men and 1woman; mean age, 64 years) underwent PULSAR for a primary tumor and SCRLM. RESULTS Seven patients (70%) with lesions in the right lobe (segments 6, 7, and 8) successfully underwent resection with a pure laparoscopic procedure while in the left semi-prone position. No patient was converted to conventional open surgery. The mean operative duration, volume of bleeding, and postoperative hospital stay were 606 ± 46 min, 585 ± 145 mL, and 18 ± 3.5 days, respectively. Although a liver abscess developed in one patient, no colonic complications or perioperative death occurred. CONCLUSION PULSAR for primary colorectal cancer and SCRLM is a feasible multidisciplinary treatment. Moreover, PULSAR can be safely and effectively performed with the patient in the semi-prone position, even when SCRLM exists in the right lobe of the liver.

Abstract
BACKGROUND The optimal management of colorectal cancer with synchronous liver metastases has not yet been elucidated. The aim of the present study was systematically to review current evidence concerning the timing and sequence of surgical interventions: colon first, liver first or simultaneous. METHODS A systematic literature review was performed of clinical studies comparing the timing and sequence of surgical interventions in patients with synchronous liver metastases. Retrospective studies were included but case reports and small case series were excluded. Preoperative and intraoperative data, length of hospital stay, perioperative mortality and morbidity, and 1-, 3- and 5-year survival rates were compared. The studies were evaluated according to a modification of the methodological index for non-randomized studies (MINORS) criteria. RESULTS Eighteen papers were included and 21 entries analysed. Five entries favoured the simultaneous approach regarding duration of procedure, whereas three showed no difference; five entries favoured simultaneous treatment in terms of blood loss, whereas in four there was no difference; and all studies comparing length of hospital stay favoured the simultaneous approach. Five studies favoured the simultaneous approach in terms of morbidity and eight found no difference, and no study demonstrated a difference in perioperative mortality. One study suggested a better 5-year survival rate after staged procedures, and another suggested worse 1-year but better 3- and 5-year survival rates following the simultaneous approach. The median MINORS score was 10, with incomplete follow-up and outcome reporting accounting primarily for low scores. CONCLUSION None of the three surgical strategies for synchronous colorectal liver metastases appeared inferior to the others.

Abstract
INTRODUCTION Recently, consensus on the optimal strategy for resectable synchronous colorectal liver metastases (LM) seems to have shifted toward simultaneous resection. However, there are still relatively few reports about simultaneous laparoscopic resection. The aim of this study is to evaluate the outcomes of patients who underwent simultaneous laparoscopic resection. METHODS We evaluated 14 patients who underwent simultaneous resection of primary colorectal cancer and LM in our hospital from 2004 to 2012. Patients were selected by matched pair analysis based on the number of LM (≤4) and tumor size (≤5 cm). We divided them into two groups: the simultaneous laparoscopic resection of primary colorectal cancer and LM (Lap-S) group (n = 7) and the simultaneous open resection of primary colorectal cancer and LM (Open-S) group (n = 7). Clinical and oncologic outcomes were compared between the groups. RESULTS The Lap-S patients were significantly older than the Open-S patients. The mean operative times of Lap-S and Open-S were 472 min and 466 min, respectively. The mean blood loss was significantly smaller in the Lap-S group (153 mL) than in the Open-S group (496 mL). There was no surgical mortality in either group. The incidence of postoperative complications in the Lap-S and Open-S groups was 12.3% and 33.0%, respectively. The mean postoperative hospital stay was significantly shorter in the Lap-S group (16 days) than in the Open-S group (36 days). There was no significant difference in long-term survival between the two groups. CONCLUSION Lap-S patients had equivalent long-term outcomes to Open-S patients. Therefore, given its technical feasibility and safety, Lap-S may be one of the most promising options in selected patients.

Abstract
BACKGROUND Simultaneous colorectal and hepatic surgery for colorectal cancer (CRC) is increasing as surgery becomes safer and less invasive. There is controversy regarding the morbidity associated with simultaneous, compared with separate or staged, resections. METHODS Data for 2005-2008 from the National Surgical Quality Improvement Program (NSQIP) were used to compare morbidity after 19,925 colorectal procedures for CRC (CR group), 2295 hepatic resections for metastatic CRC (HEP group), and 314 simultaneous colorectal and hepatic resections (SIM group). RESULTS An increasing number of simultaneous resections were performed per year. Fewer major colorectal and liver resections were performed in the SIM than in the CR and HEP groups. Patients in the SIM group had a longer operative time and postoperative length of stay compared with those in either the CR or HEP groups. Simultaneous procedures resulted in higher rates of postoperative morbidity and major morbidity than CR procedures, but not HEP procedures. This difference was driven by higher rates of wound and organ space infections, and a greater incidence of septic shock. Mortality rates did not differ among the groups. CONCLUSIONS Hospitals in the NSQIP are performing more simultaneous colonic and hepatic resections for CRC. These procedures are associated with increases in operative time, length of stay and rate of perioperative complications. Simultaneous procedures do not, however, increase perioperative mortality.

Abstract
Colorectal cancer is the third most common cancer in the Western population and has a 5-year overall survival of 5-10% when metastatic. Approximately 30% of the patients with metastatic colorectal cancer have limited disease apparently isolated to the liver and, if this can be resected, the 5-year overall survival is improved to 30-60%. Therefore, it is important to identify patients who have both resectable disease and those with initially unresectable tumors who can potentially be downsized with chemotherapy to allow resection. First-line doublet chemotherapy regimens lead to response rates of 50-60%, triplet chemotherapy regimens may result in a response rate of up to 70%, and biological agents may add to responses or induce morphologic changes that facilitate disease resection. Surgical advances in recent years have also increased resectability rates and have challenged prior rules of resectability. Local therapies including ablation and radiation, often performed in conjunction with resection, may further aid in control of disease. The aim of this article is to focus on the role of neoadjuvant therapy in the treatment of colorectal liver metastases.

Abstract
Stephen Paget's proposed an original "seed and soil" theory, with organ-preference patterns of tumor metastasis resulting in interaction between metastatic tumor cells and their specific microenvironment. There is many experimental and clinical data showing that this theory is validated. More recently, it has been suggested that early changes in the microenvironment at the distant sites, could be induced by the primary tumor, reported as "pre-metastatic niche" formation. Tumor cells could produce growth factors, cytokines which could facilitate the recruitment and the mobilization of the bone marrow-derived endothelial progenitor cells, and thus necessary for the tumor neovascularization and metastasis growth. Although the clinical value of the concept of the premetastatic niche is not yet elucidated, these data could encourage surgeons to perform the colorectal surgery first and then the liver surgery, in patients with synchronous colorectal liver metastases. The reciprocal interactions between primary tumor and microenvironment at the distant sites are therefore determinant for tumor progression. Taken together, the microenvironment is an important therapeutic target and surgeons and oncologist could discuss the choice of different surgical strategy for patient with synchronous colorectal liver metastases regarding the interaction with the microenvironment affected by primary tumor resection.

Abstract
Aproximadamente metade dos pacientes portadores de câncer colorretal apresenta metástases hepáticas durante a evolução de sua doença que afetam diretamente o prognóstico e são diretamente responsáveis por 2/3 dos óbitos relacionados à doença. Nas últimas duas décadas o tratamento das metástases hepáticas de câncer colorretal (MHCCR) proporcionou ganho expressivo na sobrevida quando todas as opções terapêuticas são colocadas à disposição do paciente. Nesse contexto, o tratamento cirúrgico persiste como a única possibilidade de cura com índices de sobrevida em cinco anos de 25 a 58%. No entanto, apenas 1/4 dos pacientes tem doença ressecável ao diagnóstico. Por essa razão, um dos pontos fundamentais no manejo atual dos pacientes com MHCCR é o desenvolvimento de estratégias que possibilitem a ressecção completa das lesões hepáticas. O advento e aperfeiçoamento dos métodos ablativos expandiram as possibilidades da terapêutica cirúrgica, além disto, o surgimento de novos esquemas quimioterápicos e a introdução das terapias-alvo proporcionou altas taxas de resposta e alteraram definitivamente o manejo destes pacientes. O tratamento multimodal e a utilização da experiência de diversas especialidades médicas permitiram que o tratamento das MHCCR se aproximasse cada vez mais do tratamento ideal, ou seja, individualizado. Baseado em uma extensa revisão da literatura e na experiência de alguns dos centros especializados mais importantes do Brasil, o Clube do Fígado de São Paulo iniciou um trabalho de discussão multi-institucional que resultou nas recomendações que se seguem. Essas recomendações, no entanto, não visam ser absolutas, mas sim ferramentas úteis no processo de decisão terapêutica desse grupo complexo de pacientes.

Abstract
UNLABELLED The optimal surgical strategy for treatment of patients with synchronous colorectal liver metastases (SCLRM) remains controversial. We conducted a systematic review and meta-analysis of all observational studies to define the safety and efficacy of simultaneous versus delayed resection of the colon and liver. A search for all major databases and relevant journals from inception to April 2012 without restriction on languages or regions was performed. Outcome measures were the primary parameters of postoperative survival, complication, and mortality, as well as other parameters of blood loss, operative time, and length of hospitalization. The test of heterogeneity was performed with the Q statistic. A total of 2,880 patients were included in the meta-analysis. Long-term oncological pooled estimates of overall survival (hazard ratio [HR]: 0.96; 95% confidence interval [CI]: 0.81-1.14; P = 0.64; I(2) = 0) and recurrence-free survival (HR: 1.04; 95% CI: 0.76-1.43; P = 0.79; I(2) = 53%) all showed similar outcomes for both simultaneous and delayed resections. A lower incidence of postoperative complication was attributed to the simultaneous group as opposed to that in the delayed group (modified relative ratio [RR] = 0.77; 95% CI: 0.67-0.89; P = 0.0002; I(2) = 10%), whereas in terms of mortality within the postoperative 60 days no statistical difference was detected (RR = 1.12; 95% CI: 0.61-2.08; P = 0.71; I(2) = 32%). Finally, selection criteria were recommended for SCRLM patients suitable for a simultaneous resection. CONCLUSION Simultaneous resection is as efficient as a delayed procedure for long-term survival. There is evidence that in SCRLM patients simultaneous resection is an acceptable and safe option with carefully selected conditions. Due to the inherent limitations of the present study, future randomized controlled trials will be useful to confirm this conclusion. (HEPATOLOGY 2013;57:2346-2357).

Abstract
Selection of the optimal surgical and interventional therapies for advanced colorectal cancer liver metastases (CRLM) requires multidisciplinary discussion of treatment strategies early in the trajectory of the individual patient's care. This paper reports on expert consensus on locoregional and interventional therapies for the treatment of advanced CRLM. Resection remains the reference treatment for patients with bilateral CRLM and synchronous presentation of primary and metastatic cancer. Patients with oligonodular bilateral CRLM may be candidates for one-stage multiple segmentectomies; two-stage resection with or without portal vein embolization may allow complete resection in patients with more advanced disease. After downsizing with preoperative systemic and/or regional therapy, curative-intent hepatectomy requires resection of all initial and currently known sites of disease; debulking procedures are not recommended. Many patients with synchronous primary disease and CRLM can safely undergo simultaneous resection of all disease. Staged resections should be considered for patients in whom the volume of the future liver remnant is anticipated to be marginal or inadequate, who have significant medical comorbid condition(s), or in whom extensive resections are required for the primary cancer and/or CRLM. Priority for liver-first or primary-first resection should depend on primary tumour-related symptoms or concern for the progression of marginally resectable CRLM during treatment of the primary disease. Chemotherapy delivered by hepatic arterial infusion represents a valid option in patients with liver-only disease, although it is best delivered in experienced centres. Ablation strategies are not recommended as first-line treatments for resectable CRLM alone or in combination with resection because of high local failure rates and limitations related to tumour size, multiplicity and intrahepatic location.

Abstract
AIM Combined resection of colorectal cancer with surgery for synchronous liver metastases (LM) still remains controversial because of the possible higher morbidity rate, the necessity of an adequate abdominal approach for both resections and the impact on oncological results. However, laparoscopy may be beneficial in terms of operative results and could facilitate this combined procedure. The aim was to assess the benefit of the laparoscopic approach for colorectal cancer resection in patients undergoing simultaneous liver resection for synchronous LM. METHOD From 2006 to 2011, all patients with colorectal cancer and resectable synchronous LM, for which the total length of the procedure was suspected to be less than 8 h, underwent colorectal laparoscopic resection combined with open and/or laparoscopic liver surgery. In order to identify selection criteria, a comparative analysis was performed between patients with and without major postoperative morbidity. RESULTS Fifty-one patients underwent combined surgery with laparoscopic colectomy (n = 31) and proctectomy (n = 20). The conversion rate was 8%. Liver resections included major surgery (n = 10) and minor surgery (n = 41). Extraction of the colorectal specimen was performed through an incision used for open liver resection, except in seven patients who underwent a total laparoscopic procedure. Overall and major morbidity rates were 55% and 25%, respectively. Median (range) hospital stay was 16 (6-40) days. Regarding patient and tumour characteristics, no independent criteria of major morbidity risk were identified. CONCLUSION This study showed that laparoscopic colorectal resection combined with liver resection for synchronous LM was feasible and safe. Moreover, laparoscopy facilitates the surgical abdominal approach for combined colorectal and liver resection.

Abstract
AIM There is no clear consensus on the optimal timing of surgical resection for synchronous colorectal liver metastases (SCLM). This study is a meta-analysis of the available evidence. METHODS Systematic review and meta-analysis of trials comparing outcomes following simultaneous resection with staged resection for SCLM published from 1990 to 2010 in PubMed, Embase, Ovid and Medline. Pooled odds ratios (OR) or weighted mean differences (WMD) with 95% confidence intervals (95% CI) were calculated using either the fixed effects or random effects model. RESULTS Nineteen non-randomized controlled trials (NRCT) studies were included in this analysis. These studies included a total of 2724 patients: 1116 underwent simultaneous resection and 1608 underwent staged resection. Meta-analysis showed that shorter hospital stay (P < 0.001) and lower total complication rate (P < 0.001) were observed in patients undergoing simultaneous resection group. The overall survival rate in the simultaneous resection group did not statistically differ with that in the staged resection group at 1 year (P = 0.13), 3 years (P = 0.26), 5 years (P = 0.38), as well as the 1, 3 and 5 years disease-free survival rates (respectively, P = 0.55; P = 0.16; P = 0.12). No significant difference was noted between the two groups in terms of mortality (P = 0.16), intraoperative blood loss (P = 0.06) and recurrence (P = 0.47). CONCLUSION Simultaneous resection is safe and efficient in the treatment of patients with SCLM while avoiding a second laparotomy. In selected patients, simultaneous resection might be considered as the preferred approach. However, the findings have to be carefully interpreted due to the lower level of evidence and the existence of heterogeneity.

Abstract
INTRODUCTION The traditional surgical management for patients presenting with synchronous colorectal liver metastases (SCLM) has been a delayed resection. However, in some centres, there has been a shift in favour of 'simultaneous' resections. The aim of this study was to use a meta-analytical model to compare the short-term and long-term outcomes in patients with synchronous colorectal liver metastases (SCLM) undergoing simultaneous resections versus delayed resections. METHOD Comparative studies published between 1991 and 2010 were included. Evaluated endpoints were intra-operative parameters, post-operative parameters, post-operative adverse events and survival. A random-effects meta-analytical model was used and sensitivity analysis performed to account for bias in patient selection. RESULTS Twenty-four non-randomized studies were included, reporting on 3159 patients of which 1381 (43.7%) had simultaneous resections and 1778 (56.3%) had delayed resections. The bilobar distribution (P = 0.01), size of liver metastases (P < 0.001) and the proportion of major liver resections (P < 0.001) was found to be higher in the delayed resection group compared to the simultaneous resection group. There was no significant difference in operative blood loss (95% CI, -279.28, 22.53; P = 0.1) or duration of surgery (WMD -23.83, 95% CI, -85.04, 37.38; P = 0.45). Duration of hospital stay was significantly reduced in simultaneous resections by 5.6 days (95% CI: 2.4-8.9 days, P = 0.007) No significant differences in post-operative complications (36% vs 37%, P = 0.27), overall survival (HR 1.00, 95% CI 0.86-1.15, P = 0.96) or disease free survival (HR 0.85, 95% CI 0.71-1.02, P = 0.08) were found. Sensitivity analysis revealed that these findings were consistent for the duration of hospital stay, post-operative complications, overall survival and disease free survival. CONCLUSION This study demonstrates that the selection criteria for patients undergoing simultaneous or delayed resections differs resulting in a discrepancy in the metastatic disease severity being compared between the two groups. The comparable intra-operative parameters, post-operative complications and survival found between the two groups suggest that delayed resections may result in better outcomes. Similarly, the reduced length of hospital stay in simultaneous resections may only be as a result of the reduced disease severity in this group. Simultaneous resections can only be recommended in patients with limited hepatic disease until prospective studies comparing similar disease burdens between the two resection groups are available.

Abstract
BACKGROUND The role of neoadjuvant chemotherapy for resectable colorectal liver metastases is a subject of debate. We compared the oncologic outcomes between neoadjuvant chemotherapy and adjuvant chemotherapy combined with surgery for resectable synchronous colorectal liver metastases. METHODS We analyzed 30 patients who underwent liver resection for resectable colorectal liver metastases combined with oxaliplatin-based neoadjuvant or adjuvant chemotherapy between May 2003 and August 2010. We assessed recurrence-free and overall survival in patients treated using neoadjuvant chemotherapy compared with those who received adjuvant chemotherapy. RESULTS Of the 30 patients with colorectal liver metastases, 15 underwent neoadjuvant chemotherapy and 15 underwent adjuvant chemotherapy. Nine (60%) patients in the adjuvant group relapsed and nine (60%) patients in the neoadjuvant group relapsed. The neoadjuvant chemotherapy group had no significant difference in recurrence-free and overall 3-y survival (37.5% versus 45.0%, P = 0.938; 44.0% versus 66.7 %, P = 0.466) compared with the adjuvant chemotherapy group. CONCLUSION Our results indicate that neoadjuvant chemotherapy is not inferior to adjuvant chemotherapy for resectable colorectal liver metastases, although the study was not randomized and included a limited number of patients.

Abstract
PURPOSE The purpose of this study was to compare the feasibility and outcomes of two-stage hepatectomy in patients with or without accompanying digestive surgery. METHODS We analyzed prospectively data from 56 patients with colorectal liver metastases undergoing two-stage hepatectomy between 1995 and 2009. Patients undergoing associated digestive resection (group I, n = 32) were compared with patients without associated digestive surgery (group II, n = 17). RESULTS The feasibility rate was 87.5% (49 patients). Neither the type and extent of hepatectomy nor the type of chemotherapy administered differed between the two groups. The median interval between hepatectomies was 1.79 and 2.07 months for groups I and II, respectively (not significant). One patient (group I) died of liver failure after the second hepatectomy. Postoperative morbidity rates were comparable: 37.5% (group I) vs. 35.5% (group II) after the first hepatectomy and 46.9% (group I) vs. 52.9% (group II) after the second hepatectomy. The median hospital stay after the first hepatectomy was longer in group I (13.5 days) than in group II (10 days) (P < 0.01). Median follow-up was 54 months. The median overall survival (OS) was 45.8 months, and 3- and 5-year OS were 58 and 31%, respectively. Median OS was longer for group II (58 months) than for group I (34 months) (P = 0.048). CONCLUSIONS Digestive tract resection associated with two-stage hepatectomy does not increase postoperative mortality or morbidity nor does it lead to delay in chemotherapy or a reduction in cycles administered. The need for digestive tract surgery should not affect the surgical management of two-stage hepatectomy patients.

Abstract
BACKGROUND This study was undertaken to assess the safety and efficacy of laparoscopic versus open resection of hepatic colorectal metastases (CRM). METHODS We reviewed retrospectively of all patients undergoing initial resection of CRM at a single institution between 1995 and 2010. The study cohort consisted of all patients undergoing laparoscopic resection and a cohort of patients undergoing open resection matched on a 4:1 basis by propensity scoring. Variables analyzed included patient and tumor characteristics, short-term outcomes, and OS and disease-free (DFS) survivals. RESULTS The 35 patients in the laparoscopic cohort and 140 patients in the open cohort were equivalent in terms of age, Charlson Comorbidity Index, tumor characteristics, and Clinical Risk Score. Similar proportions of patients in the laparoscopic and open groups underwent synchronous colectomy (9% in both; P = .976) and major hepatectomy (54% vs 51%; P = .705). Blood loss (202 vs 385 mL; P < .001), complications (23% vs 50%; P = .004), and duration of stay (4.8 vs 8.3 days; P < .001) were less in the laparoscopic cohort. Five-year OS (36% vs 42%; P = .818) and DFS (15% vs 22%; P = .346) were also similar in the laparoscopic and open groups. CONCLUSION Laparoscopic resection of hepatic CRM seems to be a beneficial alternative to open surgery in appropriately selected patients.
