Synchronous Resection

Colorectal cancer is one of the main neoplasms worldwide; at the time of diagnosis about 25% of cases already have an advanced stage with the presence of metastases. A 58-year-old female presented with nausea, vomiting, and black stools and diffuse abdominal pain associated with 7% weight loss. She was referred to our hospital with signs of digestive tract bleeding and anemic syndrome. Panendoscopy revealed body and fundus gastropathy and presence of Helicobacter pylori, and colonoscopy showed a neoplastic lesion at the ascending colon level. A synchronous resection was performed in a single surgical time of colorectal cancer and liver metastases with a duration of 4 h and bleeding of 900 mL. The oral feeding started 24 h after surgery, presenting gas channeling at 24 h and evacuations at 48 h. The total intrahospital stay was 5 days. Synchronous resection of hepatic metastases in colorectal cancer is still rarely performed, despite the fact that in recent years the number of cases has increased because of better surgical techniques. Synchronous resection of colorectal cancer and liver metastases can be performed safely, without increasing transoperative mortality when performed in specialized centers with a multidisciplinary team; however, it is essential to emphasize the importance of negative surgical margins (R0) of the primary tumor and later to be complemented with adjuvant treatment with chemotherapy.

Chemoembolization with irinotecan-loaded microspheres has proven effective in the treatment of unresectable liver metastases in the course of colorectal cancer (CRC). Most researchers recommend slowly administering the embolizate at the level of the lobar arteries, without obtaining visible stasis. However, there are reports of a relationship between postoperative embolizate retention in metastatic lesions and the response to treatment. To retain residual embolizate throughout the entire neoplastic lesion requires a temporary flow stop (stasis) within all supply vessels, which may cause temporary stasis in subsegmental or even segmental vessels. Objective: To assess the risk of complications and post-embolization syndrome severity following chemoembolization of CRC metastatic liver lesions with microspheres loaded with Irinotecan, with regard to hepatic-artery branch level of temporary stasis. Patients and methods: The study included 52 patients (29 female, 23 male) with liver metastases from CRC, who underwent 202 chemoembolization treatments (mean: 3.88 per patient) with microspheres loaded with 100 mg irinotecan. Postembolization syndrome (PES) severity and complication occurrence were assessed with regard to the hepatic-artery branch level of temporary stasis. Adverse events were assessed according to Cancer Therapy Evaluation Program Common Terminology Criteria for Adverse Events. Results: Median survival from the start of chemoembolization was 13 months. From 202 chemoembolization sessions, 15 (7.4%) significant complications were found. The study found a significant relationship between the branch level of temporary stasis and the presence of complications (p < 0.001), with the highest number of complications observed with temporary stasis in segmental vessels. PES was diagnosed after 103 (51%) chemoembolization treatments. A significant association was found between PES severity and the branch level of temporary stasis (p < 0.001). Conclusions: The branch level of temporary stasis affected the severity of post-embolization syndrome. A significant association was found between the branch level of temporary stasis obtained in chemoembolization procedures and the presence of complications. The apparent lack of change in numbers of complications when stasis was applied at tumor supply vessels or subsegmental arteries may indicate the safe use of temporary stasis in some cases where colorectal cancer metastases are treated. Further research is needed to determine the most effective chemoembolization technique.

Background: Liver metastases are the leading cause of death in patients with colorectal cancer. Despite advances in chemotherapy, surgical resection of hepatic metastases is still considered the only curative options. However, the majority of patients have inoperable disease at presentation. Perioperative chemotherapy is the most successful way for improved selection of patients for resection. The aim of the study was to demonstrate if and to what extent does bevacizumab, introduced in chemotherapy, increase response rates, and development of liver metastases. Methods: Our study included 50 patients who were divided in two groups. The experimental group included patients who were treated with bevacizumab plus chemotherapy, and the control group included patients who were treated with chemotherapy only. Results: The comparison showed that the patients who were treated with bevacizumab became candidates for resection of liver metastases in higher percentage (85%:52%). In addition, distribution of patients regarding the development of metastases resulted in statistically significant difference. Ratio between the patients with good response from the experimental and the control group was 67%:39%. Ratio of patients with stable disease was 26%:48%, and of patients with progressive disease, it was 7%:3%. The estimate of margin after resection was statistically insignificant. Conclusion: Bevacizumab in combination with chemotherapy in therapy of liver metastases from primary colorectal cancer improves and increases response rates and development of liver metastases.

The aim of this study was to identify prognostic factors affecting intrahepatic progression-free survival (ihPFS) and overall survival (OS) in patients with colorectal cancer liver metastases (CRCLM) undergoing portal vein embolization (PVE) and subsequent (extended) right hemihepatectomy. A total of 59 patients (mean age: 60.8 ± 9.3 years) with CRCLM who underwent PVE in preparation for right hemihepatectomy were included. IhPFS and OS after PVE were calculated using the Kaplan–Meier method. Cox regression analyses were conducted to investigate the association between the following factors and survival: patient age, laterality of the colorectal cancer (right- versus left-sided), tumor location (colon versus rectal cancer), time of occurrence of hepatic metastases (synchronous versus metachronous), baseline number and size of hepatic metastases, presence or absence of metastases in the future liver remnant (FLR) before PVE, preoperative carcinoembryogenic antigen (CEA) levels, time between PVE and surgery, history of neoadjuvant or adjuvant chemotherapy, and the presence or absence of extrahepatic disease before PVE. Median follow up was 18 months. The median ihPFS was 8.2 months (95% confidence interval: 6.2–10.2 months), and median OS was 34.1 months (95% confidence interval: 27.3–40.9 months). Laterality of the primary colorectal cancer was the only statistically significant predictor of ihPFS after PVE (hazard ratio (HR) = 2.242; 95% confidence interval: 1.125, 4.465; p = 0.022), with patients with right-sided colorectal cancer having significantly shorter median ihPFS than patients with left-sided cancer (4.0 ± 1.9 months versus 10.2 ± 1.5 months; log rank test: p = 0.018). Other factors, in particular also the presence or absence of additional metastases in the FLR, were not associated with intrahepatic progression-free survival. The presence of extrahepatic disease was associated with worse OS (HR = 3.050, 95% confidence interval: 1.247, 7.459; p = 0.015).

Multimodality Approach

In the last few decades there have been significant changes in the approach to rectal cancer management. A multimodality approach and advanced surgical techniques have led to an expansion of the treatment of metastatic disease, with improved survival. Hepatic metastases are present at one point or another in about 50% of patients with colorectal cancer, with surgical resection being the only chance for cure. As the use of multimodality treatment has allowed the tackling of more complicated cases, one of the main questions that remain unanswered is the management of patients with synchronous rectal cancer and hepatic metastatic lesions. The question is one of priority, with all possible options being explored. Specifically, these include the simultaneous rectal cancer and hepatic metastases resection, the rectal cancer followed by chemotherapy and then by the liver resection, and finally the “liver-first” option. This paper will review the three treatment options and attempt to dissect the indications for each. In addition, the role of laparoscopy in the synchronous resection of rectal cancer and hepatic metastases will be reviewed in order to identify future trends.

Introduction Changes in liver blood flow caused by an unknown splanchnic vasoconstrictor have been noted in colorectal cancer patients with liver metastases. This prospective study was performed to assess whether plasma levels of big endothelin-1 (big ET-1) were raised in patients with colorectal cancer. Methods Plasma samples from peripheral vein of patients who underwent surgery for primary colorectal cancer (n=60) and those with known colorectal liver metastases (n=45) for a period of 15 months were taken prior to treatment and compared to age- and sex-matched controls (n=20). Plasma samples were analysed by using a single-step sandwich enzyme immunoassay. Immunohistochemistry and in situ hybridisation were also performed on tumour sections to investigate the expression of ET-1 by cancer cells. Results The median (range) plasma concentration of big ET-1 in controls was 2.1 pg/mL (1.2–13.4 pg/mL). The median (range) plasma concentration of big ET-1 in colorectal cancer patients with no overt hepatic metastases was 3.8 pg/mL (1.2–15.8 pg/mL), p=0.002, and the median (range) plasma concentration of big ET-1 in colorectal cancer patients with hepatic metastases was 5.2 pg/mL (1.7–30 pg/mL), p=0.0001; both were significantly elevated compared to the control group. A significant difference in immunostaining for big ET-1 was noted between paired normal colonic mucosa (median score-1) and tumour sections (median score-3), p=0.01. Conclusion This study has demonstrated elevated concentrations of big ET-1 in colorectal cancer patients, especially in those with hepatic metastases. Upregulation of ET activity in colorectal cancer could be inferred by the increased immunostaining of big ET-1 in cancer cells. Therefore, plasma big ET-1 levels should be evaluated as a potential tumour marker for the identification of hepatic metastases at an earlier stage.

674 Background: Recent reports have shown that pathological response predicts for better outcome (overall survival) following preoperative chemotherapy and surgical resection of colorectal cancer (CRC) liver-only metastases. The aim of this retrospective analysis was to evaluate the effect of adding bevacizumab to standard chemotherapy on pathological response in patients with CRC liver only metastases. Methods: Patients with stage IV CRC with liver metastases who received neoadjuvant chemotherapy (oxaliplatin-or irinotecan-based) at two Spanish centres were analysed retrospectively. Pathological response was evaluated as follows: complete pathological response (cPR), PR1 (25% of residual tumour), PR2 (25–50% of residual tumour), PR3 (>50% of residual tumour). cPR or PR1 was considered to be a good response, and PR2 or PR3 a poor response. Results: A total of 81 patients were evaluated. Of these, 43 received chemotherapy alone and 38 received chemotherapy plus bevacizumab. Baseline characteristics were as follows: median age 61.0 years (range 43.0–80.0 years); male/female (67%/33%); tumour location – colon (69%) / rectum (31%); hepatic metastases – synchronous (74%) / metachronous (26%); In terms of pathological response, 58% of patients receiving bevacizumab had a good response (cPR + PR1) compared with 28% of those receiving chemotherapy alone. At the end of the analysis, 68% of patients were still alive. Conclusions: Adding bevacizumab to oxaliplatin-based chemotherapy in the neoadjuvant setting improves the pathological response of liver metastases in patients with stage IV CRC. These findings indicate that pathological response might be a good indicator of outcome for patients receiving bevacizumab in the neoadjuvant setting.

215 Background: Most of the patients with advanced colorectal cancer will develop liver metastasis, even after primary tumor resection. Although surgical resection remains the gold standard treatment of hepatic metastases, only few patients are eligible to curative resection. Radiofrequency ablation (RFA) is the most common curative alternative. Dbait are new molecules that inhibit DNA double-strand breaks repair. In vitro, Dbait has shown to increase cell death after hyperthermia. Here, we have assessed the combination of Dbait and RFA in the treatment of human colorectal cancer model xenografted in nude mice. Methods: 98 mice were flank-grafted with HT29 (human colon adenocarcinoma). When tumor reached 500 mm3, mice were sham treated (n=19), treated by Dbait via local injections (n=20), treated by RFA using an incomplete ablation scheme (n=20) or treated by combination of Dbait and RFA (n=39 separated in two Dbait regimens). After RFA, 39 mice were sacrificed for blinded pathological study, and 59 others were followed for survival analysis. Results: Mice treated by RFA-Dbait had significantly longer survival as compared to RFA alone (median survival: 56 vs 39 days, p<0.05) while RFA improved survival as compared to controls (median survival: 39 vs 28 days, p<0.05). Pathological studies of tumor slice have demonstrated significant decrease of tumor area and cancer cell viability in the RFA-Dbait group. Conclusions: While the implication of DNA repair activity in heat sensitivity remains unclear, our results show that the addition of Dbait to RFA enhances the antitumor response in this model and provide an experimental basis for the use of Dbait as an additional therapy to RFA.

616 Background: Surgical treatment of metastatic colorectal cancer remains the only method that improves overall 5-year survival. This study aimed to compare the surgical outcome and survival benefit between synchronous and staged resection of liver metastases from colorectal cancer. Methods: Clinicopathologic data, treatments, and postoperative outcomes from 110 patients who underwent simultaneous (48 patients, group A) or staged (62 patients, group B) colorectal and hepatic resections at clinic of National cancer institute in period of 2008-2013 were reviewed. Results: Postoperative complications in patients with simultaneous resections (group A) were observed in 13 cases (27.1%), including 5, 1, 4, 2, 0, and 1 of grades I, II, IIIa, IIIb, IV, and V, respectively. Similar results have been reported in group B after staged resections, where overall postoperative complications registered in 16 patients (25.8 %), including 4, 3, 6, 3, 0 of grades I, II, IIIa, IIIb, and IV respectively. Overall level of post-operative complications in the groups A and B after surgical stages finishing did not differ statistically (p=0.96). Shorter operative intervention duration was registered in the group A – (311±10.1) min, whereas in the group B it was (496.6±16.2) min (р<0.001). Patients after staged resection stayed in clinic for a longer time – 23.9±0.8 bed-days, when simultaneous resections provided with shorter recovery terms in post-operative period – 9.8±0.5 bed-days (p<0.001). Overall 3-year survival in the group of patients with simultaneous resections (group А) was 42 % and in the group B 55 % (р=0.22). Conclusions: Analysis of our research indicated necessity of the development of differentiated approach in management of synchronous colorectal liver metastatic cancer. Simultaneous resections of colorectal cancer primary lesions and hepatic metastases were safe and could serve as a primary option for selected patients. Subsequent research should be directed towards study of prognosis factors and criteria for patients’ selection for surgical treatment groups, assessment of economic effect, and patients life quality.

3507 Background: The FOXFIRE, SIRFLOX and FOXFIRE-Global (FF-SF-FFG) randomized studies evaluated the efficacy of combining first-line chemotherapy for metastatic colorectal cancer (mCRC) with selective internal radiotherapy (SIRT) using yttrium-90 resin microspheres in patients with liver metastases. The studies were designed for prospective, combined analysis of overall survival (OS). Methods: FF-SF-FFG randomized (1:1) chemotherapy-naïve mCRC patients (performance status 0/1) with liver metastases not suitable for curative resection/ablation. Arm A was oxaliplatin-based chemotherapy (mFOLFOX6/ OxMdG) ± investigator-chosen biologically targeted agent. Arm B was the same systemic therapy (oxaliplatin dose modification) + single treatment SIRT with cycle 1/2 of chemotherapy. Primary tumor in situ and/or limited extra-hepatic metastases were permitted. Minimum sample size was 1075 patients (HR 0.8, 80% power, two-sided 5% significance). Secondary outcomes included PFS, liver-specific PFS and response rate. Apart from safety, outcomes were analysed on intention-to-treat population using meta-analytic methods of pooled individual patient data. Results: Between 2006 and 2014, 1103 patients were randomized in 14 countries. Median age was 63 years (range 23-89); median follow-up 43.3 months. There were 844 deaths. There was no difference in OS (HR 1.04; 95% CI 0.90-1.19, p= 0.609) or PFS (HR 0.90, CI 0.79-1.02, p= 0.108) between Arms. Objective response rate ( p= 0.001) and liver-specific progression (HR 0.51, CI 0.43-0.62, p< 0.001) were significantly more favorable in Arm B. Patients in Arm B had higher risk of non-liver progression as first event (HR 1.98, CI 1.53-2.58, p< 0.001). Grade 3-5 adverse events were more common in Arm B (74.0%) than A (66.5%), p= 0.009. In health status questionnaires, EQ-5D utility scores were not significantly different between Arms at 6, 12 or 24 months. Conclusion: Despite higher response rates and improved liver-specific PFS, the addition of SIRT to first-line oxaliplatin-fluorouracil chemotherapy for patients with liver-only and liver-dominant mCRC did not improve OS or PFS. Clinical trial information: 83867919.

The Impact

Despite recent advances in the medical treatment of metastatic colorectal cancer (mCRC), which include irinotecan- and oxaliplatin-based first-line regimens, the concept of planned sequential therapy involving three active agents during the course of a patient's treatment and the increasing use of targeted monoclonal antibodies, 5-year survival rates for patients with advanced CRC remain unacceptably low. For patients with CRC liver metastases, liver resection remains the only chance of cure, with 5-year survival rates ranging from 25% to 40%. However, 80% to 85% of patients with stage IV CRC have liver disease which is considered unresectable at presentation. The rapid expansion in the use of improved combination chemotherapy regimens plus or minus biologics, to render initially unresectable metastases resectable has increased the percentage of patients eligible for potentially curative surgery. However, the current staging criteria for CRC patients with metastatic disease do not reflect these recent changes or the fact that there is also a large variation in the survival of patients with stage IV CRC. For example the survival for a patient with a solitary, resectable liver metastasis is better than that for a patient with stage III disease. A new staging system is therefore needed that acknowledges both the improvements that have been made in surgical techniques for resectable metastases and the impact of modern chemotherapy on rendering initially unresectable CRC liver metastases resectable, while at the same time distinguishing between patients with a chance of cure at presentation and those for whom only palliative treatment is possible.
