Abstract
INTRODUCTION Liver resection is the best treatment option for patients with resectable colorectal liver metastasis (CRLM). A 10-year follow-up can reflect the true curative potential of resection. This retrospective study investigated factors for long-term survival of CRLM patients. METHOD Data of patients who underwent liver resection for CRLM without extrahepatic disease from 1990 to 2012 at our hospital were reviewed. Patients who survived for > 10 years were compared with those who survived for < 10 years. RESULTS Totally, 315 patients were included in the study. They were divided into 2 groups: < 10-year group and > 10-year group. Patients in the < 10-year group had more tumor nodules (P = 0.016), more bilobar involvement (P = 0.004), narrower resection margin (P < 0.001), and worse disease-free and overall survival (P < 0.001). On multivariate analysis, low preoperative hemoglobin level, large number of tumor nodules, and bilobar involvement were poor prognostic factors for overall survival, while adjuvant chemotherapy was a favorable factor. Further analysis of patients with bilobar disease showed that perioperative blood transfusion was a poor prognostic factor for overall survival while adjuvant chemotherapy was a favorable one. In patients with multiple bilobar tumor nodules, adjuvant chemotherapy had a positive impact on disease-free survival and overall survival. CONCLUSIONS Patients who survived for > 10 years after liver resection for CRLM tended to have normal preoperative hemoglobin level, unilobar disease, fewer tumor nodules, and have received adjuvant chemotherapy. Adjuvant chemotherapy favorably affected long-term survival of CRLM patients.

Survival Benefit of Repeat Local Treatment in Patients Suffering From Early Recurrence of Colorectal Cancer Liver Metastases. Clin Colorectal Cancer 2021; 20:e263-e272. [PMID: 34462211 DOI: 10.1016/j.clcc.2021.07.007] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/18/2021] [Revised: 07/17/2021] [Accepted: 07/23/2021] [Indexed: 11/28/2022]
Abstract
BACKGROUND A uniform treatment strategy for patients suffering from early recurrence after local treatment of CRLM is currently lacking. The aim of this observational cohort study was to assess the potential survival benefit of repeat local treatment compared to systemic therapy in patients suffering from early recurrence of CRLM. PATIENTS AND METHODS Patients who developed recurrent CRLM within 12 months after initial local treatment with curative intent were retrospectively identified in Amsterdam University Medical Centers between 2009-2019. Differences in overall and progression-free survival among treatment strategies were assessed using multivariable Cox regression analyses. RESULTS A total of 135 patients were included. Median overall survival of 41 months [range 4-135] was observed in patients who received repeat local treatment, consisting of upfront or repeat local treatment after neoadjuvant systemic therapy, compared to 24 months [range 1-55] in patients subjected to systemic therapy alone (adjusted HR = 0.42 [95%-CI: 0.25-0.72]; P = .002). Prolonged progression-free survival was observed after neoadjuvant systemic therapy followed by repeat local treatment, as compared to upfront repeat local treatment in patients with recurrent CRLM within 4 months following initial local treatment of CRLM (adjusted HR = 0.36 [95%-CI: 0.15-0.86]; P = .021). CONCLUSION Patients with early recurrence of CRLM should be considered for repeat local treatment strategies. A multimodality approach, consisting of neoadjuvant systemic therapy followed by repeat local treatment, appeared favorable in patients with recurrence within 4 months following initial local treatment of CRLM.

Abstract
BACKGROUND Anatomical resection (AR) for colorectal liver metastasis (CLM) is disputable. We investigated the impact of AR on short-term outcomes and survival in CLM patients. METHODS Patients having hepatectomy with AR or nonanatomical resection (NAR) for CLM were reviewed. Comparison was made between AR and NAR groups. Group comparison was performed again after propensity score matching with ratio 1:1. RESULTS AR group (n = 234 vs n = 89 in NAR group) had higher carcinoembryonic antigen level (20 vs 7.8 ng/mL, p ≤ 0.001), more blood loss (0.65 vs 0.2 L, p < 0.001), more transfusions (19.2% vs 3.4%, p = 0.001), longer operation (339.5 vs 180 min, p < 0.001), longer hospital stay (9 vs 6 days, p < 0.001), more tumors (p < 0.001), larger tumors (4 vs 2 cm, p < 0.001), more bilobar involvement (20.9% vs 7.9%, p = 0.006), and comparable survival (overall, p = 0.721; disease-free, p = 0.695). After propensity score matching, each group had 70 patients, with matched tumor number, tumor size, liver function, and tumor marker. AR group had more open resections (85.7% vs 68.6%, p = 0.016), more blood loss (0.556 vs 0.3 L, p = 0.001), more transfusions (17.1% vs 4.3%, p = 0.015), longer operation (310 vs 180 min, p < 0.001), longer hospital stay (8.5 vs 6 days, p = 0.002), comparable overall survival (p = 0.819), and comparable disease-free survival (p = 0.855). CONCLUSION Similar disease-free survival and overall survival of CLM patients were seen with the use of AR and NAR. However, AR may entail a more eventful postoperative course. NAR with margin should be considered whenever feasible.

Abstract
BACKGROUND/AIM We aimed to elucidate the prognostic impact of tumor doubling time (DT) and radical surgery when classified by DT in patients with metachronous liver, lung, or peritoneal metastases of colorectal cancer (CRC). PATIENTS AND METHODS We reviewed the data of 1941 patients who underwent curative surgery for CRC and calculated DT for recurrences using computed tomography. RESULTS Short DT was an independent prognostic risk factor in liver (p<0.001) and peritoneal (p=0.03) metastases. Survival was significantly better in patients who underwent surgery than in those who did not, both in short and long DT groups in any metastatic organ (p<0.01). Patients with long DT gained significantly better prognostic benefit from surgery than those with short DT in liver (p=0.01) and peritoneal (p=0.04) metastases. CONCLUSION Surgery is recommended for resectable metastases, especially in patients with liver and peritoneal metastases with long DT.

Abstract
PURPOSE To propose a new and improved surveillance schedule for colorectal cancer (CRC) patients by focusing on the recurrence rate, resectability, and especially, the tumor doubling time (DT) of recurrent tumors. METHODS The subjects of this retrospective review were 1774 consecutive patients who underwent radical surgery for stage I-III CRC between January, 2004 and December, 2015. We calculated the DT by measuring the tumor diameter using computed tomography (CT). RESULTS The median DT for recurrences in the liver, lung, peritoneum, and other locations were 35, 72, 85, and 36 days, respectively, (p < 0.001) and tumor growth rates differed according to the organs where recurrence developed. Multiple linear regression analysis showed that the DT was strongly associated with the relapse-free interval from primary surgery (p < 0.001), and that the DT in patients with recurrence detected ≥ 3 years after primary surgery was longer by 151.1 days than that in patients with recurrence detected within 1 year after primary surgery. We proposed a less intensive surveillance, which achieved an average cost reduction of 32.5% compared with conventional surveillance in Japan. CONCLUSION We propose a new and more cost-efficient surveillance schedule for CRC surgery patients in the clinical setting.

Abstract
Introduction Growing evidence indicates the prognostic importance of the crosstalk between cancer cells and stroma through the induction of epithelial-mesenchymal transition (EMT). This study aimed to clarify the prognostic value of evaluating primary tumor histology with the anatomical extent of disease in patients with colorectal liver metastasis (CRLM). Methods Prognostic analyses were performed in 411 CRLM patients who underwent hepatectomy at two institutions. Tumors were graded into one of three histological categories based on integrated assessment of EMT-associated histology (HistologyEMT) in primary tumors, i.e., poorly differentiated clusters (PDCs) and desmoplastic reaction (DR). Results A prognostic grouping system for the anatomical extent of disease (N stage, liver metastasis number and size, and extrahepatic disease; Gradeanatomical) stratified patients into three groups with different five-year relapse-free survival (RFS) rates after hepatectomy: A, 31% (191 patients); B, 15% (124 patients); and C, 6% (96 patients; P < 0.0001). HistologyEMT (A, G1 PDC and mature-type DR; C, G3 PDC and immature-type DR; and B, others) identified 49, 120, and 242 patients with 46%, 5%, and 22% five-year RFS, respectively (P < 0.0001). Among prognostic factors, the Akaike information criterion was most favorable in Gradeanatomical, followed by HistologyEMT. Multivariate analysis demonstrated that these two factors independently impacted RFS; two-year RFS after hepatectomy in different patient groups had a wide range (10%-76%). Conclusions Histological assessment of dedifferentiation and the stromal environment of primary tumors contributed to effective risk stratification of early relapse after hepatectomy, which could be useful to determine clinical management for CRLM patients.

Prognostic significance of histological categorization of desmoplastic reaction in colorectal liver metastases. Virchows Arch 2019; 475:341-348. [PMID: 31076902 DOI: 10.1007/s00428-019-02580-2] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/15/2019] [Revised: 04/09/2019] [Accepted: 04/23/2019] [Indexed: 10/26/2022]
Abstract
Desmoplastic reaction (DR) involves the growth of fibrous or connective tissues around a tumor and has recently attracted attention as an indicator of malignant potential. Previous studies have confirmed that histological categorization of DR in the primary tumor is an independent prognostic factor in patients with colorectal liver metastases (CRLM). However, it remains unclear whether the DR status of the metastatic liver lesion (DRliver) is a useful prognostic factor. This pathological review evaluated records from 204 patients who underwent hepatectomy for CRLM at the National Defense Medical College Hospital in Japan. Each case's DRliver was classified as mature, intermediate, or immature based on the presence of keloid-like collagen and myxoid stroma in the metastatic liver lesion. This resulted in 12 cases of mature DRliver, 101 cases of intermediate DRliver, and 91 cases of immature DRliver. There was a significant correlation between the DR statuses of the primary tumor and the metastatic liver lesion (Spearman's rho = 0.3, P = 0.0001). The 5-year relapse-free survival rates after hepatectomy were 33.8% for mature/intermediate DRliver and 16.7% for immature DRliver (P = 0.0021). The 5-year overall survival rate after hepatectomy was higher in the mature/intermediate DRliver group (64.8%) than in the immature DRliver group (35.0%; P = 0.0012). The multivariate analysis confirmed that DRliver categorization could independently predict relapse-free survival and overall survival. In conclusion, DRliver categorization may be valuable for predicting prognosis after hepatectomy among patients with CRLM.

Abstract
PURPOSE The doubling times of tumor volume and tumor markers are associated with the prognosis of liver or lung metastases from colorectal cancer (CRC). However, no studies have assessed peritoneal metastases. Therefore, we aimed to elucidate the association between doubling time and the prognosis of patients who underwent radical surgery for metachronous peritoneal metastases of CRC. METHODS We calculated the tumor doubling times (TDT) of peritoneal metastases and serum carcinoembryonic antigen-doubling times (CEA-DT) in 33 consecutive patients who underwent radical surgery for metachronous peritoneal metastases between January 2006 and April 2017. The impact of short TDT and CEA-DT on overall survival (OS) and relapse-free survival (RFS) was retrospectively reviewed. RESULTS In long TDT (> 137 days) group, the 5-year OS rate was 74.1% and median OS time was 6.6 years. In long CEA-DT (> 102 days) group, the 5-year OS rate was 50.0% and median OS time was 5.6 years. Conversely, in short TDT (≤ 137 days) and CEA-DT (≤ 102 days) group, the 5-year OS rates and median OS times were both 0.0% and 3.2 years, respectively. In the multivariate analysis, short TDT was an independent risk factor for poor RFS (P = 0.006) and OS (P = 0.010). Similarly, short CEA-DT was also a poor risk factor for RFS (P < 0.001) and OS (P = 0.012). CONCLUSIONS Short TDT and CEA-DT are independent risk factors for poor OS and RFS after surgery for metachronous peritoneal metastases of CRC. TDT and CEA-DT should be considered when selecting candidates for surgical resection.

Abstract
Purpose After preoperative chemoradiotherapy followed by total mesorectal excision for locally advanced rectal cancer, patients who experience local or systemic relapse of disease may be eligible for curative salvage surgery, but the benefit of this surgery has not been fully investigated. The purpose of this study was to characterize recurrence patterns and investigate the impact of salvage surgery on survival in patients with rectal cancer after receiving multidisciplinary treatment. Patients and Methods Patients with locally advanced (cT3-4 or cN+) rectal cancer who were treated with preoperative chemoradiotherapy followed by total mesorectal excision at our institution during 1993 to 2008 were identified. We examined patterns of recurrence location, time to recurrence, treatment factors, and survival. Results A total of 735 patients were included. Tumors were mostly midrectal to lower rectal cancer, with a median distance from the anal verge of 5.0 cm. The most common recurrence site was the lung followed by the liver. Median time to recurrence was shorter in liver-only recurrence (11.2 months) than in lung-only recurrence (18.2 months) or locoregional-only recurrence (24.7 months; P = .001). Salvage surgery was performed in 57% of patients with single-site recurrence and was associated with longer survival after recurrence in patients with lung-only and liver-only recurrence ( P < .001) but not in those with locoregional-only recurrence ( P = .353). Conclusion We found a predilection for lung recurrence in patients with rectal cancer after multidisciplinary treatment. Salvage surgery was associated with prolonged survival in patients with lung-only and liver-only recurrence, but not in those with locoregional recurrence, which demonstrates a need for careful consideration of the indications for resection.

Abstract
BACKGROUND Modern chemotherapy achieves the shrinking of colorectal cancer liver metastases (CRLM) to such extent that they may disappear from radiological imaging. Disappearing CRLM rarely represents a complete pathological remission and have an important risk of recurrence. Augmented reality (AR) consists in the fusion of real-time patient images with a computer-generated 3D virtual patient model created from pre-operative medical imaging. The aim of this prospective pilot study is to investigate the potential of AR navigation as a tool to help locate and surgically resect missing CRLM. METHODS A 3D virtual anatomical model was created from thoracoabdominal CT-scans using customary software (VR RENDER(®), IRCAD). The virtual model was superimposed to the operative field using an Exoscope (VITOM(®), Karl Storz, Tüttlingen, Germany). Virtual and real images were manually registered in real-time using a video mixer, based on external anatomical landmarks with an estimated accuracy of 5 mm. This modality was tested in three patients, with four missing CRLM that had sizes from 12 to 24 mm, undergoing laparotomy after receiving pre-operative oxaliplatin-based chemotherapy. RESULTS AR display and fine registration was performed within 6 min. AR helped detect all four missing CRLM, and guided their resection. In all cases the planned security margin of 1 cm was clear and resections were confirmed to be R0 by pathology. There was no postoperative major morbidity or mortality. No local recurrence occurred in the follow-up period of 6-22 months. CONCLUSIONS This initial experience suggests that AR may be a helpful navigation tool for the resection of missing CRLM.

The aim of this prospective pilot study is to investigate the potential of AR navigation as a tool to help locate and surgically resect missing CRLM. METHODS A 3D virtual anatomical model was created from thoracoabdominal CT-scans using customary software (VR RENDER(®), IRCAD). The virtual model was superimposed to the operative field using an Exoscope (VITOM(®), Karl Storz, Tüttlingen, Germany). Virtual and real images were manually registered in real-time using a video mixer, based on external anatomical landmarks with an estimated accuracy of 5 mm. This modality was tested in three patients, with four missing CRLM that had sizes from 12 to 24 mm, undergoing laparotomy after receiving pre-operative oxaliplatin-based chemotherapy. RESULTS AR display and fine registration was performed within 6 min. AR helped detect all four missing CRLM, and guided their resection. In all cases the planned security margin of 1 cm was clear and resections were confirmed to be R0 by pathology. There was no postoperative major morbidity or mortality. No local recurrence occurred in the follow-up period of 6-22 months. CONCLUSIONS This initial experience suggests that AR may be a helpful navigation tool for the resection of missing CRLM.

Oncological Outcomes of Major Liver Resection Following Portal Vein Embolization: A Systematic Review and Meta-analysis. Ann Surg Oncol 2016; 23:3709-3717.

Abstract
BACKGROUND Preoperative portal vein occlusion with either percutaneous portal vein embolization (PVE) or portal vein ligation is routinely used to induce liver hypertrophy prior to major liver resection in patients with hepatic malignancy. While this increases the future liver remnant, and hence the number of patients suitable for resection, recent evidence suggests that induction of liver hypertrophy preoperatively may promote tumor growth and increase recurrence rates. The aims of this current study were to evaluate the impact of PVE on hepatic recurrence rate and survival in patients with colorectal liver metastases (CRLM). METHODS The MEDLINE, EMBASE and Web of Science databases were searched to identify studies assessing the oncological outcomes of patients undergoing major liver resection for CRLM following PVE. Studies comparing patients undergoing one-stage liver resection with or without preoperative PVE were included. The primary outcome was postoperative hepatic recurrence (PHR), while secondary outcomes were 3- and 5-year overall survival (OS). RESULTS Of the 2131 studies identified, six non-randomized studies (n = 668) met the eligibility criteria, comparing outcomes of patients undergoing major liver resection with or without PVE (n = 182 and n = 486, respectively). No significant difference was observed in PHR (odds ratio [OR] 0.78; 95 % confidence interval [CI] 0.42-1.44), 3-year OS (OR 0.80; 95 % CI 0.56-1.14) or 5-year OS (OR 1.12; 95 % CI 0.40-3.11). CONCLUSIONS PVE does not have any adverse effect on PHR or OS in patients undergoing major liver resection for CRLM. Further studies based on individual patient data are needed to provide definitive answers.

Abstract
BACKGROUND Colorectal cancer (CRC) accounts for 9.7% of all cancers with 1.4 million new cases diagnosed each year. 19-31% of CRC patients develop colorectal liver metastases (CRLM), and 23-38% develop extra-hepatic disease (EHD). The aim of this systematic review was to determine overall survival (OS) in patients resected for CRLM and known EHD. METHODS A systematic review was undertaken to identify studies reporting OS after resection for CRLM in the presence of EHD. Proportional meta-analyses and relative risk of death before five years were assessed between patient groups. RESULTS A total of 15,144 patients with CRLM (2308 with EHD) from 52 studies were included. Three and 5-year OS were 58% and 26% for lung, 37% and 17% for peritoneum, and 35% and 15% for lymph nodes, respectively. The combined relative risk of death by five years was 1.49 (95% CI = 1.34-1.66) for lung, 1.59 (95% CI = 1.16-2.17) for peritoneal and 1.70 (95% CI = 1.57-1.84) for lymph node EHD, in favour of resection in the absence of EHD. CONCLUSION This review supports attempts at R0 resection in selected patients and rejects the notion that EHD is an absolute contraindication to resection.

Abstract
BACKGROUND Some reports have shown that a significant number of patients experience recurrence, even after 5 or more years after surgery for colorectal liver metastases (CLMs). This study aimed to determine the actual cure rate and identify clinical characteristics among long-term survivors. METHODS A prospectively maintained database was used to retrospectively review patients who underwent liver resection for CLM between 1994 and 2001. RESULTS A total of 130 patients underwent liver resection for CLM with a complete 10-year follow-up. The 10-year disease-specific survival rate was 31.1%, and the survival curve reached a plateau after 10 years from the time of hepatic resection. There were 35 actual 10-year survivors. Multivariate analysis revealed that female patients and those with negative surgical margins were independent prognostic factors for disease-specific survival. CONCLUSION A 10-year survival following initial hepatectomy should be defined as cure.

Abstract
Although the molecular mechanism of desmoplastic reaction (DR) for providing aggressive tumor characteristics is increasingly recognized, the prognostic role of DR has not been investigated in colorectal liver metastasis (CRLM). A pathologic review of 412 patients who underwent hepatectomy for CRLM at 2 independent institutions was conducted. DR in primary tumors was classified as mature, intermediate, or immature on the basis of the existence of keloid-like collagen and myxoid stroma-distinctive histologic products of extracellular matrix remodeling. With respect to DR, 137, 122, and 153 patients were classified as mature, intermediate, and immature, respectively. Immature DRs were associated with higher T and N stages, higher primary tumor grade, synchronous and larger size of liver metastasis, and extrahepatic disease (P≤0.0001 to 0.002). DR significantly influenced the rate of recurrence in extrahepatic sites, including the lung, peritoneum, and local region in the primary tumor (P≤0.0001 to 0.03), rather than the remnant liver. Five-year overall survival rates after hepatectomy were the highest in the mature group (58.9%), followed by intermediate (42.1%) and immature (26.7%) groups. A significant prognostic impact of DR was observed in subset analyses for institutions, primary tumor location, and timing and number of liver metastases. Multivariate analysis revealed that DR was an independent prognostic factor along with T stage of the primary tumor, size of liver metastasis, and extrahepatic disease. Characterizing DR in the primary tumor on the basis of histologic products of cancer-associated fibroblasts is valuable in evaluating prognostic outcome after hepatectomy in CRLM patients.

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

Abstract
BACKGROUND Surgical resection for patients with colorectal liver metastases (CRLM) can offer patients a significant survival benefit. We hypothesised that patients with CRLM and extra hepatic disease (EHD) undergoing metastasectomy had comparable survival and describe outcomes based on the distribution of metastatic disease. METHODS A systematic search using a predefined registered protocol was undertaken between January 2003 and June 2012. Primary exposure was hepatic resection for CRLM and primary outcome measure was overall survival. Meta-regression techniques were used to analyse differences between patients with and without extra hepatic disease. FINDINGS From a pool of 4996 articles, 50 were retained for data extraction (3481 CRLM patients with EHD). The median survival (MS) was 30.5 (range, 9-98) months which was achieved with an operative mortality rate of 0-4.2%. The 3-year and 5-year overall survival (OS) were 42.4% (range, 20.6-77%) and 28% (range, 0-61%) respectively. Patients with EHD of the lungs had a MS of 45 (range, 39-98) months versus lymph nodes (portal and para-aortic) 26 (range, 21-48) months versus peritoneum 29 (range, 18-32) months. The MS also varied by the amount of liver disease - 42.2months (<two lesions) versus 39.6months (two lesions) versus 28months (⩾three lesions). INTERPRETATION In the evolving landscape of multimodality therapy, selective hepatic resection for CRLM patients with EHD is feasible with potential impact on survival. Patients with minimal liver disease and EHD in the lung achieve the best outcome.

Abstract
BACKGROUND The prognostic factors for patients with colorectal cancer liver metastasis (L-Mets) have not been fully described. METHODS Resected specimens were obtained surgically from 1998 to 2008 at our university hospital. We investigated whether the status of two primary lesion cancer stem biomarkers, CD44 and CD133, were maintained in L-Mets and whether these markers were L-Mets prognostic factors. To investigate the CD133 and CD44 status, proliferation, invasiveness, and chemoresistance were examined immunohistochemically by using MIB-1, E-cadherin, and ABC-G2. RESULTS The CD44-positive rate in primary lesions and L-Mets was 41.4 and 58.7 %, respectively. There was no correlation of CD44 expression between primary lesions and L-Mets (r = 0.250, p = 0.071). The CD133-positive rate in primary lesions and L-Mets was 53.6 and 44.6 %, respectively. There was no correlation of CD133 expression between primary lesions and L-Mets (r = 0.219, p = 0.135). In the CD133-negative group, the MIB-1 index was significantly higher than in the CD133-positive group (61.6 vs. 46.3 %, p = 0.003), and E-cadherin expression was significantly lower in the CD133-negative group compared with the CD133-positive group (29.3 vs. 46.8 %, p = 0.001). Absence of CD133 expression in L-Mets correlated with poor overall survival (p = 0.006), and multivariate regression analysis showed that it was an independent marker for poor survival (hazard ratio 0.320, p = 0.0016). CONCLUSIONS The absence of CD133 expression in L-Mets was an independent marker and a poor prognostic factor, possibly because of increased proliferation and invasiveness.

Abstract
PURPOSE The aims of this study were to assess the risk of early recurrence after liver resection for colorectal metastases (CRLM) and its prognostic value; identify early recurrence predictive factors; clarify the effect of perioperative chemotherapy on its occurrence; and elucidate the best early recurrence management. METHODS Patients of the LiverMetSurvey registry who underwent complete liver resection (R0/R1) between 1998 and 2009 were reviewed. Early recurrence was defined as any recurrence that occurred within 6 months after resection. RESULTS A total of 6,025 patients were included; 2,734 (45.4 %) had recurrence, including 639 (10.6 %) early recurrences. Early recurrence was mainly hepatic (59.5 vs. 54.4 % for late recurrences; p = 0.023). Independent risk factors of early recurrence were: T3-4 primary tumor (p = 0.0002); synchronous CRLM (p = 0.0001); >3 CRLM (p < 0.0001); 0-mm margin liver resection (p = 0.003); and associated intraoperative radiofrequency ablation (p = 0.0005). Response to preoperative chemotherapy (complete/partial) and administration of adjuvant chemotherapy reduced early recurrence risk (p = 0.003 and p < 0.0001, respectively). Intraoperative ultrasonography reduced hepatic early recurrence rate (p = 0.025). Early recurrence negatively affected prognosis: 5-year survival 26.9 versus 49.4 % for the late recurrence group (p < 0.0001, median follow-up 34.4 months). Overall, 234 (36.6 %) patients with early recurrence underwent re-resection. These patients had survival rates higher than non-re-resected patients (5-year survival 47.2 vs. 8.9 %; p < 0.0001) and similar to re-resected patients for late recurrence (48.7 %). Chemotherapy before early recurrence resection improved later survival (5-year survival 61.5 vs. 43.7 %; p = 0.028). CONCLUSIONS Early recurrence risk is enhanced for extensive disease after poor preoperative disease control and inadequate surgical treatment, but is reduced after adjuvant chemotherapy. Although early recurrence negatively affects prognosis, re-resection may restore better survival. Chemotherapy before early recurrence resection is advocated.

Abstract
BACKGROUND For patients undergoing liver resection for colorectal metastases, specific clinico-pathological variables have been shown to be prognostic at baseline. This study analyses how the prognostic capability of these variables changes in a conditional survival model. METHODS Retrospective review of a prospectively maintained database of patients who underwent an R0 resection of colorectal liver metastases from 1994 to 2004 at a single institution. RESULTS In total, 807 patients were identified, with an 87-month median follow-up for survivors. Five- and 10-year disease-specific survivals (DSS) were 68% and 55%, respectively. The probability of further survival increased as the survival time increased. For 3-year survivors (n = 504), DSS were no longer significantly different between patients with a low (0-2) or high (3-5) clinical risk score (CRS, P = 0.19). On multivariate analysis, independent predictors of DSS for 3-year survivors were recurrence within the first 3 years after a liver resection, a pre-operative carcinoembryonic antigen (CEA) >200 ng/ml and disease-free interval <12 months prior to the diagnosis of liver metastasis. However, for those patients who were recurrence free at 1 year, no clinico-pathological variables retained prognostic significance. DISCUSSION After 3 years of DSS and 1 year of recurrence-free survival, baseline clinico-pathological variables have a limited ability to predict future survival. Early post-operative recurrence appears to be the most useful single clinical feature in estimating conditional DSS.

Effect of preoperative chemotherapy on postoperative liver regeneration following hepatic resection as estimated by liver volume. World J Surg Oncol 2013; 11:65. [PMID: 23497123 PMCID: PMC3621216 DOI: 10.1186/1477-7819-11-65] [Citation(s) in RCA: 15] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/06/2012] [Accepted: 02/15/2013] [Indexed: 01/10/2023] Open
Abstract
Background In order to analyze postoperative liver regeneration following hepatic resection after chemotherapy, we retrospectively investigated the differences in liver regeneration by comparing changes of residual liver volume in three groups: a living liver donor group and two groups of patients with colorectal liver metastases who did and did not undergo preoperative chemotherapy. Methods This study included 32 patients who had at least segmental anatomical hepatic resection. Residual liver volume, early postoperative liver volume, and late postoperative liver volume were calculated to study the changes over time. From the histopathological analysis of chemotherapy-induced liver disorders, the effect on liver regeneration according to the histopathology of noncancerous liver tissue was also compared between the two colorectal cancer groups using Kleiner’s score for steatohepatitis grading {Hepatology, 41(6):1313–1321, 2005} and sinusoidal obstruction syndrome (SOS) grading for sinusoidal obstructions {Ann Oncol, 15(3):460–466, 2004}. Results Assuming a preoperative liver volume of 100%, mean late postoperative liver volumes in the three groups (the living liver donor group and the colorectal cancer groups with or without chemotherapy) were 91.1%, 80.8%, and 81.3%, respectively, with about the same rate of liver regeneration among the three groups. Histopathological analysis revealed no correlation between either the Kleiner’s scores or the SOS grading and liver regeneration. Conclusions As estimated by liver volume, the level of liver regeneration was the same in normal livers, tumor-bearing livers, and post-chemotherapy tumor-bearing livers. Liver regeneration was not adversely affected by the extent to which steatosis or sinusoidal dilatation was induced in noncancerous tissue by chemotherapy in patients scheduled for surgery.

Abstract
Background Hepatic metastases develop in approximately 50% of colorectal cancer (CRC) cases. We performed a review and meta-analysis to evaluate survival after resection of CRC liver metastases (CLMs) and estimated the summary effect for seven prognostic factors. Methods Studies published between 1999 and 2010, indexed on Medline, that reported survival after resection of CLMs, were reviewed. Meta-relative risks for survival by prognostic factor were calculated, stratified by study size and annual clinic volume. Cumulative meta-analysis results by annual clinic volume were plotted. Results Five- and 10-year survival ranged from 16% to 74% (median 38%) and 9% to 69% (median 26%), respectively, based on 60 studies. The overall summary median survival time was 3.6 (range: 1.7–7.3) years. Meta-relative risks (95% confidence intervals) by prognostic factor were: node positive primary, 1.6 (1.5–1.7); carcinoembryonic antigen level, 1.9 (1.1–3.2); extrahepatic disease, 1.9 (1.5–2.4); poor tumor grade, 1.9 (1.3–2.7); positive margin, 2.0 (1.7–2.5); >1 liver metastases, 1.6 (1.4–1.8); and >3 cm tumor diameter, 1.5 (1.3–1.8). Cumulative meta-analyses by annual clinic volume suggested improved survival with increasing volume. Conclusion The overall median survival following CLM liver resection was 3.6 years. All seven investigated prognostic factors showed a modest but significant predictive relationship with survival, and certain prognostic factors may prove useful in determining optimal therapeutic options. Due to the increasing complexity of surgical interventions for CLM and the inclusion of patients with higher disease burdens, future studies should consider the potential for selection and referral bias on survival.

Abstract
Liver resection is considered the therapeutic gold standard for primary and metastatic liver neoplasms. The reduction of postoperative complications and mortality has resulted in a more aggressive approach to hepatic malignancies. For the most part, results of liver surgery have been published by highly experienced institutions, but the observations of highly specialized units results may not reflect the current status of hepatic surgery, underestimating mortality and complications. The objective of this study is to evaluate morbidity and mortality as a result of liver resection for primary and metastatic lesions, analyzing a large number of studies with a meta-analytic process taking into account the overdispersion of data. An extensive literature search has been conducted, and 148 papers published between January 2000 and April 2008, including a total of 36,629 patients from both high-volume and low volume institutions, were included in the meta-analysis. A beta binomial model was used to provide a robust estimate of the summary event rate by pooling overdispersion binomial data from different studies. Overall morbidity and mortality after liver surgery were 29.32 per cent and 3.15 per cent, respectively. Significantly higher postoperative mortality was observed after liver resection for hepatocellular carcinomas and primary hepatic tumors. The application of a beta binomial model to correct for overdispersion of liver surgery data showed significantly higher postoperative mortality rates in patients with hepatocellular carcinomas or primary hepatic tumors after liver resection.

Abstract
BACKGROUND Liver resection (LR) is the only potentially curative treatment of colorectal liver metastases (CRLM). Its outcome over the past 2 decades was studied using actual 5-year survival rates. METHODS Data of 393 consecutive patients who underwent LR for CRLM at Mauriziano Umberto I (Turin) until June 2005 were analyzed. Excluding R2 resections (n = 4) or incomplete 5-year follow-up (n = 13), 376 patients were divided according to LR date into groups A (before 1995: 90 patients), B (1995-2000: 94 patients), C (2001-2005: 192). RESULTS Group C presented increased multiple and bilobar metastases compared with combined group A and B (C vs AB: 54.7% vs 40.2%, P = 0.005; 28.1% vs 19.0%, P = 0.038, respectively), decreased metastases diameter (C vs AB: 32 vs 40 mm, P = 0.0001). The 5-year overall survival, calculated excluding 4 operative mortalities (group AB), increased over the years (A, 20.5%; B, 32.6%; C, 46.4%; P < 0.0001). Early recurrences (1 year) were not decreased, extrahepatic recurrences even increased (C vs AB: 17.2% vs 8.6%, P = 0.015). Recurrence-free 5-year survival improved (C vs AB: 23.4% vs 13.9%, P = 0.019) linked to decreased liver recurrences (C vs AB: 26.8% vs 37.4%, P = 0.023). Resection rate (59% overall for liver recurrence) increased along with 5-year survival after recurrence (A, 4.0%; B, 14.2%; C, 21.4%; P < 0.0001). Survival improvement was confirmed for multiple (P = 0.003) and synchronous metastases (P = 0.008), N+ tumors (P = 0.005), and in patients without chemotherapy (P = 0.001). CONCLUSIONS Long-term outcome of LR for CRLM improved over 20 years, even in patients with negative prognostic factors, linked to hepatic recurrences reduction and increased survival after recurrence.

Abstract
BACKGROUND As surgical resection of colorectal liver metastases (CLM) remains the only treatment for cure, efforts to extend the surgical indications to include patients with multiple bilobar CLM have been made. This study evaluated the long-term outcome, safety and efficacy of two-stage hepatectomy (TSH) for CLM in a large cohort of patients. METHODS Patients undergoing surgery between December 1996 and December 2009 were reviewed. The early postoperative and long-term outcomes as well as the patterns of failure to complete TSH and its clinical implications were analysed. RESULTS Eighty patients were scheduled to undergo TSH. Sixty-one patients had completion of TSH combined with (58 patients), or without (3) portal vein embolization/ligation (PVE/PVL). Five patients were excluded after first-stage hepatectomy and 14 after PVE/PVL. The 5-year overall survival rate and median survival in patients who completed TSH were 32 per cent and 39·6 months respectively, and corresponding recurrence-free values were 11 per cent and 9·4 months respectively. Six patients were alive beyond 5 years after TSH. Multivariable logistic regression analysis showed that failure to complete TSH was driven by two independent prognostic scenarios: three or more CLM in the future remnant liver (FRL) combined with age over 70 years predicted tumour progression after first-stage hepatectomy, and three or more CLM in the FRL combined with carcinomatosis at the time of first-stage hepatectomy predicted the development of additional FRL metastases after PVE/PVL. CONCLUSION A therapeutic strategy using TSH provided acceptable long-term survival with no postoperative mortality. Further efforts are needed to increase the number of patients who undergo TSH successfully.

Abstract
Metastatic liver disease is a challenging and life-threatening situation often with dismal prognosis. Nearly half of the patients with colorectal cancer develop liver metastasis during the course of their diseases. Hepatic resection is the treatment of choice in patients with colorectal liver metastasis. This study was conducted to compare the results of patients undergoing simultaneous liver and colorectal resection for synchronous liver metastasis and of those for whom a colorectal and liver resection was made separately. A retrospective analysis was performed on 1597 patients who underwent surgery because of colorectal cancer between January 1999 and December 2008. The results of the treatment were separately evaluated in case of the 152 patients who had liver metastasis. The proportion of the liver metastasis was 9.52%. The metastases arose in 40.8% from the rectum and in 31.8% from the sigmoid colon. It proved to be inoperable in 109 (71.7%) of the 152 patients who had liver metastasis. Simultaneous liver resection was performed because of synchronous metastasis in 14 (32.6%) cases (Group 1) and two step resection in 29 (67.4%) cases (Group 2). In case of synchronous operations only minor liver surgery was done. The mean size of the metastasis was 2.6 cm in diameter in Group 1 and 4.6 cm in Group 2 (p<0.005). The transfused blood volume was 0.3 U/patient. Only minor complications could be observed in Group 1. The hospitalization was 13.1 days in Group 1 and 11.7 days in Group 2. The mean survival time was 37.3 and 47.9 months (p<0.005). Simultaneous liver resection seems to be a safe procedure on those patients who develop small metastases with a limited number. However, the optimal timing of the liver resection and the identification of patients who will have the greatest benefit in survival still remain obscure.

Abstract
BACKGROUND During the last two decades, resection of colorectal liver metastases (CLM) in selected patients has become the standard of care, with 5-year survival rates of 25-58%. Although a substantial number of actual 5-year survivors are reported after resection, 5-year survival rates may be inadequate to evaluate surgical outcomes because a significant number of patients experience a recurrence at some point. OBJECTIVES This study aimed to analyse longterm results and prognostic factors in liver resection for CLM in patients with complete 10-year follow-up data. METHODS A total of 369 patients who underwent liver resection for CLM between 1985 and 1998 were identified from a bi-institutional database. Postoperative deaths and patients with extrahepatic disease were excluded. Clinicopathological prognostic factors were analysed using univariate and multivariate analyses. RESULTS The sample included 309 consecutive patients with complete 10-year follow-up data. Five- and 10-year overall survival rates were 32% and 23%, respectively. Overall, 93% of recurrences occurred within the first 5 years of follow-up, but 11% of patients who were disease-free at 5 years developed later recurrence. Multivariate analysis demonstrated four independent negative prognostic factors for survival: more than three metastases; a positive surgical margin; tumour size >5 cm, and a clinical risk score >2. CONCLUSIONS Five-year survival rates are not adequate to evaluate surgical outcomes of patients with CLM. Approximately one-third of actual 5-year survivors suffer cancer-related death, whereas patients who survive 10 years appear to be cured of disease.

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

Abstract
AIM Cancer death in the early period after hepatectomy still occurs in patients with colorectal liver metastasis (CLM). We examined the relationship between clinicopathological parameters and survival periods in 130 CLM patients who underwent hepatectomy. PATIENTS/METHODS Patients were divided into four groups: Group 1 (5-year survivors without tumor relapse), Group 2 (survivors at 2-5 years), Group 3 (cancer death at 2-5 years), and Group 4 (cancer death within 2 years). RESULTS A short surgical margin was frequent in Group 4 compared to Group 1 (31 vs. 78%, P<0.05). Primary node-positive status, absence of fibrous pseudo-capsular formation, higher Clinical Risk Score, and tumor recurrence within 12 months were frequent in Group 4 (P<0.05). Multivariate analysis revealed a short surgical margin (HR; 3.5) and early tumor relapse (HR; 5.9) as independently significant related parameters (P<0.05). CONCLUSIONS Sufficient surgical margins and careful follow-up for early tumor relapse may be important for improving postoperative outcomes for CLM patients.

Abstract
BACKGROUND Few studies identifying variables associated with prognosis after resection of colorectal liver metastases (CLM) account for treatment with multiagent chemotherapy (fluoropyrmidines with irinotecan, oxaliplatin, bevacizumab, and/or cetuximab). The objective of this retrospective study was to determine the effect of multiagent chemotherapy on long-term survival after resection of CLM. METHODS Demographics, clinicopathologic tumor characteristics, treatments, and long-term outcomes were reviewed. RESULTS From 1996 to 2006, 230 patients underwent resection of CLM. Treatment strategies before and after resection included fluoropyrimidine monotherapy (n = 34 and n = 39), multiagent chemotherapy (n = 81 and n = 73), and observation (n = 115 and n = 118). Prehepatectomy treatment strategy was not associated with overall survival. Actuarial 4-year survival was 63%, 39%, and 40% for patients treated with multiagent chemotherapy, fluoropyrimidine monotherapy, and observation after hepatectomy, p = 0.06. Posthepatectomy multiagent chemotherapy (p = 0.04, HR 0.52 [0.27-1.03]), duration of posthepatectomy chemotherapy treatment of 2 months or longer (p = 0.05, HR 0.49 [0.25-0.99]), carcino-embryonic antigen level >10 ng/mL (p = 0.03, HR 2.09, 95% CI [1.32-3.32]), and node positive primary tumor (p = 0.002, HR 1.79 [1.06-3.02]) were associated with overall survival in multivariate analysis. CONCLUSIONS The association of posthepatectomy multiagent chemotherapy with overall survival in this retrospective study indicates the need for prospective randomized trials comparing multiagent chemotherapy and fluoropyrimidine monotherapy for CLM.

Abstract
BACKGROUND/AIM Liver metastases are most frequently the result of colorectal carcinoma. The aim of this study was to analyse early results of operative treatment of the patients with the liver metastases of colorectal carcinoma. METHODS This retrospective, prospective study included 387 patients with colorectal carcinoma operated during the period from 2005-2007. All the patients were submitted to oncologic surgery protocol. The functional state of the liver was assessed, especially in the patients with hemotherapy. Diagnostic protocol further included color Doppler ultrasonography of the liver and port system, as well as spiral computed tomography includy angiography. Nine (5.7%) of the patients were submitted to explorative laparotomy. RESULTS Of all the patients 157 (40.6%) had metastases in the liver, synhronous 78 (20.15%) and metachronous 79 (20.45%), Forty two (26.7%) patients were indicated for the liver resection. In 33 (21%) of them it was performed successfully. There were 18 females and 15 males of the average age 60.09 (42-81) years. Up to 4 metastases had 90.9% of the patients and in 9.09% had up to 5 and more metastases. On average, metastases occupied 2.6 of the liver segments. There were 21.2% of solitary lesions (7 patients), 63.6% of multilple unilobular (21 patients) and 15.15% of multiple bilobular metastases (5 patients). Liver resection was done using ultraharmonic scalpel. At spacious liver resections we used a device for intraoperative saving of blood (cell saver) and applied a technique of selective hepatic vascular exclusion. An average disease-free interval was 16.7 months. There were 60.6% of anatomical liver resections and 39.4% of atypical resections. In 31.1% of the operated patients we made resection on up to two segments of the liver and in 30.3% we made resection of four segments. An average number of segments where resection had been performed was 2.65 and the duration of operation was 143 minutes. In 39.4% of the cases we used a technique of liver vascular isolation, an average duration was 38 minutes. In 30.3% of resections we used cell saver and 70% of operated patients were transfused. On average, 493 ml of blood was transfused. Of the total number of resections, 90.9% was of the type R0, 9.09% of the type R1. An average duration of postoperative hospitalization was 10.6 days. Operative morbidity rate was 15.15% and operative mortality 3.03%. During a six-month observing there were not any mortality or repeated metastases in liver. CONCLUSION Anatomic liver resection including selective vascular hepatic excision by the use of an ultraharmonic scalpel and cell saver is considered to be efficient and secure method for the reduction of intraoperative and postoperative complications rendering good surgical results.

Ann Surg Oncol 2008; 15:1908-17. [PMID: 18459005 DOI: 10.1245/s10434-008-9925-y] [Citation(s) in RCA: 54] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/19/2007] [Revised: 03/28/2008] [Accepted: 03/29/2008] [Indexed: 12/15/2022]
Abstract
BACKGROUND This study investigates oncological risks and benefits of portal occlusion (PO) in major resection for colorectal liver metastases (CLM). METHODS Between 1995 and 2004, 107 patients were scheduled for major hepatectomy for CLM. Of these, 53 patients were selected for PO due to insufficient future liver remnant (FLR), and 54 patients had straightforward hepatectomy. Associations of clinicopathologic factors with resectability, and outcome after PO were analyzed. RESULTS 21 of 53 patients (39.6%) after PO were unresectable. These patients had a significant smaller volume of the FLR than the 32 resected patients after PO (P = .029). In total, 17 patients (80.9%) did not undergo resection due to cancer progression. Among these, 11 patients (52.4%) exhibited either a progression of known metastases located in the occluded lobes, or new metastases in the nonoccluded portion of the liver. In another 4 individuals (19%), the decision against resection resulted from insufficient hypertrophy of the FLR. Following major hepatectomy, the 5-year survival was 43.66%. Although there was a significantly higher rate of extended hepatectomies versus formal hepatectomies (P < .001), more bilobar distributed metastases versus unilobar manifestations (P = .015), and a smaller resection margin (P = .01) in patients who had PO, no adverse effect on mortality, morbidity, recurrence and survival was observed. CONCLUSION Unresectability after PO is a major problem that warrants multidisciplinary improvements, and randomization to resection with or without PO remains ethically problematic. However, following adequate patient selection, PO may provide a significant survival benefit for patients with prior unresectable CLM.
