Perioperative Outcomes Following Combined Versus Isolated Colorectal and Liver Resections: Insights From a Contemporary, National, Propensity Score-Based Analysis. ANNALS OF SURGERY OPEN 2021; 2:e050. [PMID: 36714392 PMCID: PMC9872861 DOI: 10.1097/as9.0000000000000050] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/13/2021] [Accepted: 01/31/2021] [Indexed: 02/01/2023] Open
Abstract
Our objective was to compare outcomes following combined versus isolated resections for metastatic colorectal cancer and/or liver metastases using a large, contemporary national database. Background Controversy persists regarding optimal timing of resections in patients with synchronous colorectal liver metastases. Methods We analyzed 11,814 patients with disseminated colorectal cancer and/or liver metastases who underwent isolated colon, rectal, or liver resections (CRs, RRs, or LRs) or combined colon/liver or rectal/liver resections (CCLRs or CRLRs) in the National Surgical Quality Improvement Program Participant Use File (2011-2015). We examined associations between resection type and outcomes using univariate/multivariate analyses and used propensity adjustment to account for nonrandom receipt of isolated versus combined resections. Results Two thousand four hundred thirty-seven (20.6%); 2108 (17.8%); and 6243 (52.8%) patients underwent isolated CR, RR, or LR; 557 (4.7%) and 469 (4.0%) underwent CCLR or CRLR. Three thousand three hundred ninety-five patients (28.7%) had serious complications (SCs). One hundred forty patients (1.2%) died, of which 113 (80.7%) were failure to rescue (FTR). One thousand three hundred eighty-six (11.7%) patients experienced unplanned readmission. After propensity adjustment and controlling for procedural complexity, wound class, and operation year, CCLR/CRLR was independently associated with increased risk of SC, as well as readmission (compared with LR). CCLR was also independently associated with increased risk of FTR and death (compared with LR). Conclusions Combined resection uniformly confers increased risk of SC and increased risk of mortality after CCLR; addition of colorectal to LR increases risk of readmission. Combined resections are less safe, and potentially more costly, than isolated resections. Effective strategies to prevent SC after combined resections are warranted.

Laparoscopic partial hepatectomy is cost-effective when performed in high volume centers: A five state analysis. Am J Surg 2021; 222:577-583. [PMID: 33478723 DOI: 10.1016/j.amjsurg.2020.12.051] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/08/2020] [Revised: 12/08/2020] [Accepted: 12/27/2020] [Indexed: 01/22/2023]
Abstract
BACKGROUND Prior studies comparing the efficacy of laparoscopic (LHR) and open hepatic resection (OHR) have not evaluated inpatient costs. METHODS We conducted a retrospective cohort study using the Healthcare Cost and Utilization Project State Inpatient Databases to identify patients undergoing hepatic resection between 2010 and 2014. RESULTS 10,239 patients underwent hepatic resection. 865 (8%) underwent LHR and 9374 (92%) underwent OHR. On adjusting for hospital volume, patients undergoing LHR had a lower risk of respiratory (OR 0.64, 95% CI [0.52, 0.78]), wound (OR 0.48; 95% CI [0.29, 0.79]) and hematologic (OR 0.57; 95% CI [0.44, 0.73]) complication as well as a lower risk of being in the highest quartile of cost (0.58; 95% CI [0.43, 0.77]) than those undergoing OHR. Patients undergoing LHR in very high volume (>314 hepatectomies/year) centers had lower risk-adjusted 90-day aggregate costs of care than those undergoing OHR (-$8022; 95% CI [-$11,732, -$4311). DISCUSSION Laparoscopic partial hepatectomy is associated with lower risk of postoperative complication than OHR. This translates to lower aggregate costs in very high-volume centers.

Abstract
OBJECTIVE The aim of this study was to evaluate trends over time in perioperative outcomes for patients undergoing hepatectomy. BACKGROUND As perioperative care and surgical technique for hepatectomy have improved, the indications for and complexity of liver resections have evolved. However, the resulting effect on the short-term outcomes over time has not been well described. METHODS Consecutive patients undergoing hepatectomy during 1998 to 2015 at 1 institution were analyzed. Perioperative outcomes, including the comprehensive complication index (CCI), were compared between patients who underwent hepatectomy in the eras 1998 to 2003, 2004 to 2009, and 2010 to 2015. RESULTS The study included 3707 hepatic resections. The number of hepatectomies increased in each era (794 in 1998 to 2003, 1402 in 2004 to 2009, and 1511 in 2010 to 2015). Technical complexity increased over time as evidenced by increases in the rates of major hepatectomy (20%, 23%, 30%, P < 0.0001), 2-stage hepatectomy (0%, 3%, 4%, P < 0.001), need for portal vein embolization (5%, 9%, 9%, P = 0.001), preoperative chemotherapy for colorectal liver metastases (70%, 82%, 89%, P < 0.001) and median operative time (180, 175, 225 minutes, P < 0.001). Significant decreases over time were observed in median blood loss (300, 250, 200 mL, P < 0.001), transfusion rate (19%, 15%, 5%, P < 0.001), median length of hospitalization (7, 7, 6 days, P < 0.001), rates of CCI ≥26.2 (20%, 22%, 16%, P < 0.001) and 90-day mortality (3.1%, 2.6%, 1.3%, P < 0.01). On multivariable analysis, hepatectomy in the most recent era 2010 to 2015 was associated with a lower incidence of CCI ≥26.2 (odds ratio 0.7, 95% confidence interval 0.6-0.8, P < 0.0001). CONCLUSION Despite increases in complexity over an 18-year period, continued improvements in surgical technique and perioperative outcomes yielded a resultant decrease in CCI in the most current era.

Simultaneous resection of colorectal cancer with synchronous liver metastases; a practice survey. HPB (Oxford) 2020; 22:728-734. [PMID: 31601509 DOI: 10.1016/j.hpb.2019.09.012] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/29/2019] [Revised: 08/07/2019] [Accepted: 09/16/2019] [Indexed: 12/12/2022]
Abstract
BACKGROUND We examined surgeon practice intentions and barriers to performing simultaneous resections for colorectal cancer with synchronous liver metastases. METHODS We electronically surveyed North American surgeons who provide colorectal cancer care with a pilot-tested questionnaire. Four clinical scenarios of increasing complexity were presented. Perceived outcomes of and barriers to simultaneous resection were assessed on a 7-point Likert scale. We compared results between general and hepatobiliary surgeons. RESULTS Responses (rate 20%, 234/1166) included 50 general and 134 hepatobiliary surgeons. High likelihood scores for support of simultaneous resection among general and hepatobiliary surgeons, respectively, included the following for: minor liver and low complexity colon, 83% and 98% (p < 0.001); minor liver and rectal resection, 57% and 73% (p = 0.042); complex liver and low complexity colon resection, 26% and 24% (p = 0.858); and, complex liver and rectal resection, 11% and 7.0% (p = 0.436). Among hepatobiliary surgeons, the most common barriers to simultaneous resections were patient comorbidities and lung metastases, whereas certain general surgeons additionally identified transfer of care. CONCLUSIONS Surgeon support for simultaneous resection was high for cases with minor hepatectomy, and low for cases involving major hepatectomy. These results suggest that clinical trials should involve patients with limited disease to evaluate post-operative complications and cost.

Abstract
BACKGROUND Approximately 20% of patients with colorectal cancer (CRC) present with synchronous liver metastases (CRLM). The decision to resect simultaneously or sequentially remains controversial. The primary aim of this study was to determine whether simultaneous resection of CRC and CRLM is associated with increased complications compared to isolated resection. STUDY DESIGN Prospective data from the American College of Surgeons (ACS) NSQIP, including the ACS NSQIP procedure-specific colectomy and hepatectomy modules from 2014 to 2017, were reviewed in a retrospective cohort study. Primary study outcome was combined 30-day complication rates; secondary outcomes included colectomy and hepatectomy-specific complication. Multivariable logistic regression was performed to control for confounding factors associated with postoperative complication. RESULTS A total of 23,643 patients underwent colectomy, 7,462 hepatectomy, and 592 simultaneous resection for CRC and CLRM. Overall morbidity was higher among patients treated with simultaneous resection (29.9%) compared with either isolated colorectal (22.2%) or hepatic resection (17.1%; p < 0.001). Additionally, postoperative ileus (36.4% vs 19.1%) and anastomotic failure (7.9% vs 3.8%) were more common after simultaneous resection compared with colorectal resection (p < 0.05). Similarly, rates of bile leak (8.3% vs 6.2%, p = 0.195) and post-hepatectomy liver failure (8.7% vs 3.8%, p < 0.001) were higher after simultaneous resection compared with isolated hepatectomy. By multivariable logistic regression, simultaneous resection was associated with increased overall complication compared with isolated colon (odds ratio 1.64 [95% CI 1.36 to 1.96]) or liver resection (odds ratio 2.11 [95% CI 1.75 to 2.55]), as well as increased procedure-specific complication. CONCLUSIONS Although simultaneous resection offers definitive resection for patients with synchronous CRC and CRLM, it is associated with significantly increased 30-day overall and procedure-specific postoperative morbidity.

Abstract
BACKGROUND The objective of the current study was to compare outcomes among patients combined colon (CR) and liver resection (LR) for the treatment of simultaneous colorectal liver metastasis (CRLM) versus patients undergoing two-stage CR and LR. METHODS Patients undergoing surgery for CRLM between 2004 and 2014 were identified using the Nationwide Inpatient Sample (NIS). Propensity-score matching was used to compare patients undergoing CR + LR with patients undergoing two-stage CR and LR. RESULTS Among 83,410 patients, CR + LR was performed in 5659 (6.7%), stage C + LR was performed in 5659 (6.7%), while isolated CR and LR was performed in 70,177 (84.0%) and 7574 (9.3%) patients, respectively. The number of patients undergoing CR + LR increased from 423 in 2004 to 580 in 2014 (Δ = +37%). Patients undergoing CR + LR had lower postoperative morbidity (CR + LR vs. two-staged CR and LR: 38.5% vs. 61.2%), shorter LOS (median LOS: 8 days [IQR: 7-12] vs. 14 days [IQR: 10-21]), and lower postoperative mortality (3.1% vs. 5.9%) versus patients undergoing two-stage CR and LR. Compared with patients undergoing two-staged CR and LR, median hospital costs were $13,093 lower for patients undergoing CR + LR (median costs: $36,775 [IQR: 26,416-54,245] vs. $23,682 [IQR: 16,299-32,996]). CONCLUSION CR + LR was increasingly performed for treatment of CRLM. Compared with two-staged CR and LR, CR + LR was associated with improved outcomes and lower costs.

World J Gastrointest Oncol 2018; 10:293-316. [PMID: 30364774 PMCID: PMC6198303 DOI: 10.4251/wjgo.v10.i10.293] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/08/2018] [Revised: 08/05/2018] [Accepted: 08/21/2018] [Indexed: 02/05/2023] Open
Abstract
Synchronous colorectal carcinoma (SCRC) indicates more than one primary colorectal carcinoma (CRC) discovered at the time of initial presentation, accounts for 3.1%-3.9% of CRC, and may occur either in the same or in different colorectal segments. The accurate preoperative diagnosis of SCRC is difficult and diagnostic failures may lead to inappropriate treatment and poorer prognosis. SCRC requires colorectal resections tailored to individual patients, based on the number, location, and stage of the tumours, from conventional or extended hemicolectomies to total colectomy or proctocolectomy, when established predisposing conditions exist. The overall perioperative risks of surgery for SCRC seem to be higher than for solitary CRC. Simultaneous colorectal and liver resection represents an appealing surgical strategy in selected patients with CRC and synchronous liver metastases (CRLM), even though the cumulative risks of the two procedures need to be adequately evaluated. Simultaneous resections have the noticeable advantage of avoiding a second laparotomy, give the opportunity of an earlier initiation of adjuvant therapy, and may significantly reduce the hospital costs. Because an increasing number of recent studies have shown good results, with morbidity, perioperative hospitalization, and mortality rates comparable to staged resections, simultaneous procedures can be selectively proposed even in case of complex colorectal resections, including those for SCRC and rectal cancer. However, in patients with multiple bilobar CRLM, major hepatectomies performed simultaneously with colorectal resection have been associated with significant perioperative risks. Conservative or parenchymal-sparing hepatectomies reduce the extent of hepatectomy while preserving oncological radicality, and may represent the best option for selected patients with multiple CRLM involving both liver lobes. Parenchymal-sparing liver resection, instead of major or two-stage hepatectomy for bilobar disease, seemingly reduces the overall operative risk of candidates to simultaneous colorectal and liver resection, and may represent the most appropriate surgical strategy whenever possible, also for patients with advanced SCRC and multiple bilobar liver metastases.

Abstract
BACKGROUND Many centers use the Pringle's maneuver during liver resections. Since this maneuver might impair healing of bowel anastomoses, we evaluated its influence on the healing of colonic anastomosis in rats. METHODS Male Wistar rats underwent median laparotomy and sigmoid resection with end-to-end anastomosis under inhalation anesthesia. Thereafter, rats received a 25 minutes Pringle's maneuver (PM, group 1) or were kept under anesthesia for the same period of time (group 2). The anastomotic bursting pressure (BP) was measured on postoperative days (POD) 3, 6 and 9. Hematoxylin and Eosin (H&E) staining was used for histopathological evaluation of the anastomosis. The Mann-Whitney U and χ2 -tests were used, p<0.05 values were considered significant. RESULTS All animals (n=48) lost body weight (BW) until POD3 (95.2% vs. 85.7%, p=0.003), and BW remained lower after PM (106.2% vs. 92.8%, p=0.001). The anastomotic BP was lower in group 1 compared to group 2 on POD 3 (116mmHg vs. 176.28mmHg, p=0.001), POD 6 (182.8mmHg vs. 213mmHg, p=0.029) and POD 9 (197.2mmHg vs. 251.7mmHg, p=0.009), and mortality was higher in group 1 (1 vs. 7, p=0.022). CONCLUSIONS Pringle's maneuver increases anastomotic complications in rats. Therefore, a Pringle's maneuver should be avoided during simultaneous liver and colorectal surgery.

Abstract
MicroRNA-21-3p (miR-21-3p), the passenger strand of pre-mir-21, has been found to be high-expressing in various cancers and to be associated with tumour malignancy, which is proposed as a novel focus in malignant tumours. Colorectal cancer (CRC), currently known as one of the most prevalent malignancy, is a leading cause of cancer death. This study aimed to investigate the key role of miR-21-3p in CRC by inhibiting its expression using transfection with miR-21-3p inhibitors into human CRC HCT116 cells. Results showed that the expression of miR-21-3p was higher than other CRC cells used in the study including Lovo, HT29, Colo320 and SW480 cells, inhibition of which suppressed the proliferation and induced cell cycle arrest in HCT116 cells. Besides, transfection with miR-21-3p inhibitors also attenuated cell migration and invasion, and induced apoptosis as well. Moreover, luciferase assay confirmed RBPMS as a direct target of miR-21-3p in HCT116 cells. Further, miR-21-3p inhibitors increased the nuclear accumulation of Smad4 and reduced phosphorylation of ERK. Interestingly, we found that silence of RBPMS using RNA interference (siRNA) not only elevated the cell viability but also increased the phosphorylation of ERK and reversed the nuclear accumulation of Smad4 induced by miR-21-3p inhibitors in HCT116 cells. Data suggest that inhibition of miR-21-3p suppresses cell proliferation, invasion as well as migration and induces apoptosis by directly targeting RBPMS through Smad4/ERK signalling pathway in HCT116 cells. Our study demonstrates miR-21-3p as a potent target for suppressing tumour progression of CRC which may have implications in CRC therapy in the future.

Abstract
BACKGROUND Simultaneous resection for colorectal cancer with synchronous liver metastases is an established alternative to a staged approach. This study aimed to compare these approaches with regards to economic parameters and short-term outcomes. METHODS A retrospective cohort analysis was conducted between 2005 and 2016. The primary outcome was cost per episode of care. Secondary measures included 30-day clinical outcomes. A multivariate analysis was performed to determine the adjusted effect of a simultaneous surgical approach on total cost of care. RESULTS Fifty-three cases were identified; 27 in the staged approach, and 26 in the simultaneous group. Age (P = 0.49), sex (P = 0.20), BMI (P = 0.74), and ASA class (P = 0.44) were comparable between groups. Total cost ($20297 vs $27522), OR ($6830 vs $10376), PACU ($675 vs $1182), ward ($7586 vs $11603) and pharmacy costs ($728 vs $1075) were significantly less for the simultaneous group (P < 0.05). The adjusted rate ratio for total cost of care in the staged group compared to simultaneous group was 1.51 (95%CI: 1.16-1.97, P < 0.05). The groups had comparable Clavien-Dindo scores (P = 0.89), 30-day readmissions (P = 0.44), morbidity (P = 0.50) and mortality (P = 1.00). CONCLUSIONS Our study demonstrates that a simultaneous approach is associated with a significantly lower total cost while maintaining comparable short-term outcomes.

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
The optimal surgical strategy for treating colorectal cancer with synchronous liver metastases is subject to debate. The current study sought to evaluate the outcomes of simultaneous colorectal cancer and liver metastases resection in a single center. Prospectively collected data on all patients with synchronous colorectal liver metastases who underwent simultaneous resection with curative intent were analyzed retrospectively. Patient outcomes were compared depending on the primary tumor location and type of liver resection (major or minor). Between January 2005 and August 2016, 108 patients underwent simultaneous resection of primary colorectal cancer and liver metastases. The tumor was localized to the right side of the colon in 24 patients (22%), to the left side in 40 (37%), and to the rectum in 44 (41%). Perioperative mortality occurred in 3 patients (3%). Postoperative complications were noted in 32 patients (30%), and most of these complications (75%) were grade 1 to 3 according to the Clavien-Dindo classification. Neither perioperative mortality nor the rate of postoperative complications after simultaneous resection differed among patients with cancer of the right side of the colon, those with cancer of the left side of the colon, and those with rectal cancer (4%, 2.5%, and 2%, respectively, p = 0.89) and (17%, 33%, and 34%, respectively; p = 0.29)]. The 5-year overall survival of the entire sample was 54% and the 3-year overall survival was 67 %. In conclusion, simultaneous resection for primary colorectal cancer and liver metastases is a safe procedure and can be performed without excess morbidity in carefully selected patients regardless of the location of the primary tumor and type of hepatectomy.

Abstract
Objectives To assess the impact of minor, major and individual complications on prolonged length of hospital stay in patients with colorectal cancer (CRC) after surgery using multivariate models. Methods This was a retrospective review of data from patients who underwent surgery for stage I-III CRC at two medical centres in southern Taiwan between 2005-2010. Information was derived from four databases. Multivariate logistic regression methods were used to assess the impact of complications on prolonged length of stay (PLOS) and prolonged postoperative length of stay (PPOLOS). Results Of 1658 study patients, 251 (15.1%) experienced minor or major postsurgical complications during hospitalizations. Minor and major complications were significantly associated with PLOS (minor, odds ratio [OR] 3.59; major, OR 8.82) and with PPOLOS (minor, OR 5.55; major, OR 10.00). Intestinal obstruction, anastomosis leakage, abdominal abscess and bleeding produced the greatest impact. Conclusions Minor and major complications were stronger predictors of prolonged hospital stay than preoperative demographic and disease parameters. Compared with the PLOS model, the PPOLOS model better predicted risk of prolonged hospital stay. Optimal surgical and medical care have major roles in surgical CRC patients.

Abstract
INTRODUCTION AND AIM Patients with colorectal cancer (CRC) may develop liver metastases. Surgical resection remains the best treatment of choice for colorectal liver metastases (CRLM) according to resectability criteria, with a long-term survival of 25% up to 41% after 5 years. Advanced age is associated with a higher incidence and co-morbidity, particularly cardiovascular disease, as well as deteriorating physiological reserves. The aim of this study was to analyse the overall and disease-free survival for patients with CRLM according to their chronological age. METHODS Patients with CRLM were enrolled in the study. Data on gender, age, co-morbidity, metastasis characteristics (number, size and total metastatic volume (TMV)), use of perioperative chemotherapy and operative and post-operative complications were collected. Then, according to recent World Health Organization (WHO) guidelines, the patients were grouped by age. Statistical analysis was performed using the software R (ver. 2.14.1). RESULTS Hepatic resection was performed in 149 patients (21 patients in the very elderly group, 79 in the elderly group and 49 in the younger group). The three groups were comparable in terms of operative duration, transfusion rate, length of high-dependency unit (HDU) stay and post-operative hospital stay. The very elderly group showed a non-significant increase in post-operative morbidity. The 30-day and 60-day/inpatient mortality rates increased with age without any significant statistically difference between the three groups (very elderly group 4.8% and 4.8%; elderly group: 2.5% and 3.8%; and younger group 0% and 2%). At 5 years, the overall survival was 28.6% for very elderly patients (≥75 years), 33.3% for elderly patients (≥65 to <75 years) and 43.5% for younger patients (≤65 years). The 1-, 3- and 5-year disease-free survival was similar across the groups. CONCLUSIONS Liver resection for CRLM in carefully selected patients above the age of 75 can be performed with acceptable morbidity and mortality rates, similar to those in younger patients. Moreover, the severity of CRLM in elderly patients is proven to be lesser than in younger patients. Thus, we can conclude that advanced chronological age cannot be considered a contraindication to hepatic resection for CRLM.

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
BACKGROUND The optimal surgical strategy for treating colorectal cancer liver metastases (CRLM) in patients requiring major liver resection (MLR) is controversial, especially in rectal cancer patients. METHOD Between March 2004 and January 2015, 103 patients underwent MLR for CRLM and underwent MLR simultaneously with colorectal surgery (simultaneous group; n = 55) or MLR after colorectal surgery (liver-only group; n = 48). RESULTS There were no significant differences in sex, age, ASA score, BMI, size and number of liver metastases, liver resection margin, surgical outcomes, and estimated blood loss. The rates of postoperative complications (simultaneous group vs. liver-only group; 76.4 % vs. 62.5 %; P = 0.126) and major complications (29.0 % vs. 25.0 %; P = 0.513) were also similar in both groups. The time to starting a soft diet was longer in the simultaneous group (6.0 days vs. 3.4 days; P < 0.001), but the length of hospital stay was similar (14.9 days vs. 13.3 days; P = 0.345). There were no perioperative deaths, anastomotic leakage, or septic complications. Among patients who underwent rectal surgery, the frequency of complications was greater in the simultaneous group (87.0 % vs. 56.2 %; P = 0.031), but there was no difference in major complications (34.7 % vs. 25.0 %; P = 0.822). The postoperative morbidity index was 0.204 and 0.180 in the simultaneous and liver-only groups, respectively, in all patients, and was 0.227 and 0.136, respectively, in the rectal surgery subgroup. CONCLUSION Simultaneous MLR is feasible and safe in synchronous CRLM patients, including rectal cancer patients.

Abstract
BACKGROUND Liver resection before primary cancer resection is a novel strategy advocated for selected patients with synchronous colorectal liver metastases (sCRLM). This study measured outcomes in patients with sCRLM following a liver-first or classical approach, and used a validated propensity score. METHODS Clinical, pathological and follow-up data were collected prospectively from consecutive patients undergoing hepatic resection for sCRLM at a single centre (2004-2014). Cumulative disease-free survival (DFS), cancer-specific survival (CSS) and overall survival (OS) were calculated by means of Kaplan-Meier analysis. Survival differences were analysed in the whole cohort and in subgroups matched according to Basingstoke Predictive Index (BPI). RESULTS Of 582 patients, 98 had a liver-first and 467 a classical approach to treatment; 17 patients undergoing simultaneous bowel and liver resection were excluded. The median (i.q.r.) BPI was significantly higher in the liver-first compared with the classical group: 8·5 (5-10) versus 8 (4-9) (P = 0·030). Median follow-up was 34 months. The 5-year DFS rate was lower in the liver-first group than in the classical group (23 versus 45·6 per cent; P = 0·001), but there was no difference in 5-year CSS (51 versus 53·8 per cent; P = 0·379) or OS (44 versus 49·6 per cent; P = 0·305). After matching for preoperative BPI, there was no difference in 5-year DFS (37 versus 41·2 per cent for liver-first versus classical approach; P = 0·083), CSS (51 versus 53·2 per cent; P = 0·616) or OS (47 versus 49·1 per cent; P = 0·846) rates. CONCLUSION Patients with sCRLM selected for a liver-first approach had more oncologically advanced disease and a poorer prognosis. They had inferior cumulative DFS than those undergoing a classical approach, a difference negated by matching preoperative BPI.

Abstract
OBJECTIVE(S) Higher-volume centers demonstrate better perioperative outcomes for complex surgical interventions, though resource utilization implications of this hospital-level variation are unclear. We hypothesized that for hepatic lobectomy, higher operative volume correlates with better outcomes and lower costs. METHODS From 2009 to 2011, 4163 patients undergoing hepatic lobectomy were identified from the University HealthSystems Consortium database. Univariate, multivariate logistic regression, and decision analytic models were constructed to identify differences in hospital utilization and cost. Cost included both index and readmission hospitalizations, when applicable. RESULTS The annual number of hepatic lobectomies performed by the institutions within the study ranged from 1 to 86. The median age of the 4163 patients was 58 years with a roughly equal gender split (M/F 49 %:51 %) and a racial breakdown which reflected that of the general US population. For all patients, the overall perioperative mortality rate was 2.3 % and the 30-day readmission rate was 13.4 %. Hospitals performing >30 hepatic lobectomies per year had significantly lower mortality and readmission rates than those hospitals performing ≤15 lobectomies annually (both p < 0.05). On multivariate analysis, higher severity of illness (odd ratio (OR) 2.13, 95 % confidence interval (CI) [1.48-3.07], p < 0.001), discharge to rehab (OR 1.84, [1.28-2.64], p < 0.001), home with home health care (OR 1.38, [1.08-1.76], p = 0.01), and surgery at a low-volume hospital (OR 1.49, [1.18-1.88], p < 0.001) were significant predictors of readmission. Conversely, surgical intervention at high-volume centers was associated with decreased risk of readmission (OR 0.67, [0.53-0.85], p < 0.001). When both index and readmission costs were considered, per-patient cost at low-volume centers was 21.9 % higher than at high-volume centers ($19,669 vs. $16,137). Sensitivity analyses adjusting for perioperative mortality and readmission at all centers did not significantly change the analysis. CONCLUSIONS These data, for the first time, demonstrate that hospital volume in hepatic lobectomy is an important, modifiable risk factor for readmission and cost. To optimize resource utilization, patients undergoing complex hepatic surgery should be directed to higher-volume surgical institutions.

Abstract
BACKGROUND The liver is a common site of primary and metastatic cancer. Liver-directed therapies are commonly used to treat cancer involving the liver. We report on the patterns, predictors, and outcomes of liver-directed therapies in hospitalized cancer patients in the United States. METHODS Data were obtained from all U.S. states that contributed to the Nationwide Inpatient Sample maintained by the Agency for Healthcare Research and Quality between 2006 and 2010. Univariate and multivariate testing was used to identify factors significantly associated with patient outcome. RESULTS For the 5-year period of interest, 12,540 patient discharges were identified. Mean age in the sample was 60 years. Primary liver lesions (n = 8840) made up 26.9% of the sample; the remaining cases were metastases. Most procedures were performed in large (79%) urban (98%) hospitals and in patients with insurance (97.9%). The most common intervention was partial hepatectomy (42.7%), followed by open (9.9%), percutaneous (7.2%), and laparoscopic (5.04%) ablation of liver lesions; embolization (9.8%); and liver transplantation (2.64%). The incidence of in-hospital mortality was very low (2.4%), and the complication rate was 12.2%. Complications such as acute liver necrosis, ascites, hepatic coma, hepatorenal syndrome, liver abscess, and high number of comorbid illnesses (>8) accounted for 60% of the in-hospital mortality. CONCLUSIONS The low rate of morbidity and mortality associated with liver-directed therapies in hospitalized cancer patients supports the continuing utility of such procedures in the management of primary and metastatic liver cancer. The patterns of health disparities observed with respect to the use of liver-directed therapies are concerning.

Abstract
PURPOSES The correct timing of hepatectomy in patients with synchronous colorectal liver metastases is unclear. The aim of this study was to assess the clinical value of simultaneous resection (SR) for patients with colorectal cancer and synchronous liver metastases. METHODS Between January 2006 and December 2013, 158 patients underwent resection of primary colorectal cancer and liver metastases. Sixty-three patients possessed synchronous colorectal liver metastases. Of those with synchronous colorectal liver metastases, 41 patients (65 %) underwent SR, and 22 (35 %) underwent delayed resection (DR). The clinicopathologic and operative data and the surgical outcomes of the patients in the SR and DR groups were retrospectively analyzed. RESULTS The type of primary/liver resection, liver resection time, total blood loss volume, R0 resection rate, and morbidity rate were similar between the two groups. The SR group was associated with a shorter total postoperative hospital stay (21 vs 32 days, p < 0.001). However, the overall survival rate was similar between the two groups (3-year survival, 65.6 % in the SR group versus 66.8 % in the DR group, p = 0.054). CONCLUSION Simultaneous resection of colorectal cancer and synchronous liver metastases is associated with a comparable morbidity rate and shorter hospital stay, even when following rectal resection and major hepatectomy.

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
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.

Outcomes of extended versus limited indications for patients undergoing a liver resection for colorectal cancer liver metastases. HPB (Oxford) 2014; 16:550-9.

Abstract
BACKGROUND Currently, resection criteria for colorectal cancer liver metastases (CRCLM) are only limited by remnant liver function. Morbidity and survival after a partial hepatectomy with limited or extended indication criteria were compared. METHODS/DESIGN Between 1991 and 2010, patients undergoing a liver resection for CRCLM with limited (n = 169) or extended indication criteria (n = 129) were retrospectively identified in a prospectively collected single-centre database. Limited indication criteria were defined as less than three unilateral, not centrally located liver metastases in the absence of extra hepatic metastases. The extended criteria were only limited by predicted remnant liver volume and patients fitness. Data on co-morbidity, resection margin, short- and long-term morbidity, disease-free (DFS) and overall survival were compared. RESULTS Patients with limited indications had less major complications (19.5% vs. 33.1%, P < 0.01), longer overall survival of 68.8 months [confidence interval (CI) 46.5-91.1] vs. 41.4 months (CI 33.4-49.0, P ≤ 0.001) and longer median DFS of 22.0 months [confidence interval (CI) 15.8-28.2] vs 10.2 months (CI 8.4-11.9, P < 0.001) compared with the extended indication group. Cure rates, defined as 10-year DFS, were 35.5% and 15.8%, respectively. Fewer patients in the extended indication group underwent an R0 resection (92.9% vs. 77.5%, P < 0.001). Only 17% of all R1 resected patients had recurrences at the transection plane. CONCLUSION A partial hepatectomy for CRCLM with extended indications seems justified but is associated with higher complication rates, earlier recurrence and lower overall survival compared with limited indications. However, the median 5-year survival was substantial and a cure was achieved in 15.8% of patients.

Abstract
Transforming growth factor β (TGF-β)/Smad signaling is involved in colorectal carcinoma (CRC) development and progression. The frequent loss of SMAD4 is associated with liver metastasis and poor prognosis of CRC, but the underlying mechanism remains elusive. This study aimed to elucidate the role of Smad-independent TGF-β signaling in CRC metastasis. Immunohistochemistry showed that Smad4 level was negatively correlated with TNM stage and phospho-ERK level in human CRCs and liver metastasis samples. Knockdown of Smad4 in CT26 and HCT116 cells activated ERK pathway, altered the expression of MMP2 and COX-2, promoted cell motility, migration, and invasion in vitro, enhanced metastasis, and shortened the survival of metastatic tumor-bearing mice. MEK inhibitor U0126 and GSK1120212 inhibited the motility, migration, and invasion of Smad4 knockdown cells, inhibited metastasis, and prolonged the survival of metastatic tumor-bearing mice. Furthermore, MEK inhibitor could reverse the changes of phospho-ERK, MMP2, and COX-2 levels. In conclusion, our results indicate that ERK pathway plays a key oncogenic role in CRC with SMAD4 inactivation mutations, and implicate ERK as a potential therapeutic target for CRC liver metastasis.
