Phase 0 Study of Vandetanib-Eluting Radiopaque Embolics as a Preoperative Embolization Treatment in Patients with Resectable Liver Malignancies.

PURPOSE: To assess the safety and tolerability of a vandetanib-eluting radiopaque embolic (BTG-002814) for transarterial chemoembolization (TACE) in patients with resectable liver malignancies. MATERIALS AND METHODS: The VEROnA clinical trial was a first-in-human, phase 0, single-arm, window-of-opportunity study. Eligible patients were aged ≥18 years and had resectable hepatocellular carcinoma (HCC) (Child-Pugh A) or metastatic colorectal cancer (mCRC). Patients received 1 mL of BTG-002814 transarterially (containing 100 mg of vandetanib) 7-21 days prior to surgery. The primary objectives were to establish the safety and tolerability of BTG-002814 and determine the concentrations of vandetanib and the N-desmethyl vandetanib metabolite in the plasma and resected liver after treatment. Biomarker studies included circulating proangiogenic factors, perfusion computed tomography, and dynamic contrast-enhanced magnetic resonance imaging. RESULTS: Eight patients were enrolled: 2 with HCC and 6 with mCRC. There was 1 grade 3 adverse event (AE) before surgery and 18 after surgery; 6 AEs were deemed to be related to BTG-002814. Surgical resection was not delayed. Vandetanib was present in the plasma of all patients 12 days after treatment, with a mean maximum concentration of 24.3 ng/mL (standard deviation ± 13.94 ng/mL), and in resected liver tissue up to 32 days after treatment (441-404,000 ng/g). The median percentage of tumor necrosis was 92.5% (range, 5%-100%). There were no significant changes in perfusion imaging parameters after TACE. CONCLUSIONS: BTG-002814 has an acceptable safety profile in patients before surgery. The presence of vandetanib in the tumor specimens up to 32 days after treatment suggests sustained anticancer activity, while the low vandetanib levels in the plasma suggest minimal release into the systemic circulation. Further evaluation of this TACE combination is warranted in dose-finding and efficacy studies.

Evaluating the Effectiveness of Yttrium-90 Glass Microspheres in the Treatment of Hepatocellular Carcinoma, Intrahepatic Cholangiocarcinoma, and Metastatic Colorectal Cancer in Practice: Protocol for the Prospective PROACTIF Phase IV Registry Study in France.

PRIMARY OBJECTIVE: Recently, selective internal radiation therapy using yttrium-90 (Y90) glass microspheres (TheraSphere™) was approved for reimbursement by health authorities in France. The PROACTIF study aims to gather data on effectiveness, patient quality of life, and safety with use of Y90 glass microspheres in real-world clinical settings in France. INCLUSION CRITERIA: Patient with a diagnosis of hepatocellular carcinoma (HCC), intrahepatic cholangiocarcinoma (iCC), and/or metastatic colorectal cancer (mCRC) who was treated with a dose of Y90 glass microspheres that has been reimbursed in France and who do not oppose use of their personal medical data. EXCLUSION CRITERIA: If data collection is opposed, treatment is reimbursed but not administered, or treatment is administered but not reimbursed. OUTCOME MEASURES: Primary outcome measures include overall survival from time of Y90 glass microsphere treatment and quality of life, as assessed using the Functional Assessment of Cancer Therapy- Hepatobiliary questionnaire. ESTIMATED NUMBER OF PATIENTS TO BE INCLUDED: This is an open study and there is no set number of patients; 115 have already been enrolled. PLANNED SUBGROUP ANALYSES: Analyses will be stratified by disease state (HCC, iCC, or mCRC). Subgroups to be analyzed include age group, unilobar/bilobar disease at baseline, Eastern Cooperative Oncology Group (ECOG) status at baseline, liver tumor burden at baseline, target lesion size, and standard versus multi-compartment personalized dosimetry treatment. PLANNED RECRUITMENT AND OBSERVATION PERIOD: Recruitment includes patients who are prescribed and treated with a commercial vial of Y90 glass microspheres between 01 January 2019 and 31 December 2024. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT04069468.

Selective Internal Radiation Combined with Chemotherapy Maintains the Quality of Life in Intrahepatic Cholangiocarcinomas.

BACKGROUND: In the Yttrium-90 Microspheres in Cholangiocarcinoma (MISPHEC) single-arm phase 2 trial, concomitant chemotherapy and selective internal radiotherapy (SIRT) showed antitumor activity as a first-line treatment of unresectable intrahepatic cholangiocarcinomas (ICCs). In this sub-analysis, we aimed to evaluate one of the secondary endpoints, the health-related quality of life (QoL), evaluated with an EORTC QLQ-C30 instrument at the baseline and during treatment. METHODS: The MISPHEC trial included treatment-naïve patients with an unresectable ICC between November 2013 and June 2016. Patients received concomitant first-line chemotherapy with cisplatin and gemcitabine for 8 cycles; SIRT was administered during cycle 1 (for patients with unilobar disease) or cycles 1 and 3 (for patients with bilobar disease) using glass Yttrium-90 microspheres. We evaluated the QoL-measured by the QLQ-C30 questionnaire-at the baseline, every 8 weeks during chemotherapy and follow-up, between 12 and 15 weeks after embolization and every 12 weeks after a liver resection if applicable. RESULTS: A total of 41 patients were included, of which 34 completed questionnaires at the baseline. No clinically significant changes in the global health score or the sub-scales of the QLQ-C30 were observed during follow-up. The physical, social and role function mean score worsened during treatment and fatigue, nausea and pain scores increased although the differences were not clinically significant. In patients undergoing subsequent surgery, the QoL was not impaired. CONCLUSIONS: A combination of SIRT and chemotherapy with gemcitabine and cisplatin as the first-line treatment of unresectable ICCs was found to maintain the QoL.

Yttrium-90 Radioembolization for the Treatment of Solitary, Unresectable HCC: The LEGACY Study.

BACKGROUND AND AIMS: Locoregional therapies, including yttrium-90 radioembolization, play an important role in the treatment of unresectable HCC. The aim of the LEGACY (Local radioEmbolization using Glass Microspheres for the Assessment of Tumor Control with Y-90) study was to evaluate objective response rate (ORR) and duration of response (DoR) in patients with solitary unresectable HCC treated with yttrium-90 glass microspheres. APPROACH AND RESULTS: LEGACY is a multicenter, single-arm, retrospective study conducted at three sites that included all eligible, consecutive patients with HCC treated with radioembolization between 2014 and 2017. Eligibility criteria included solitary HCC ≤ 8 cm, Child-Pugh A cirrhosis, and Eastern Cooperative Oncology Group performance status 0-1. Primary endpoints were ORR and DoR based on modified Response Evaluation Criteria in Solid Tumors in the treated area (localized), as evaluated by blinded, independent, central review. Radioembolization was performed with intent of ablative-level dosimetry in a selective fashion when possible. Overall survival was evaluated using Kaplan-Meier and multivariate Cox proportional hazards. Among the 162 patients included, 60.5% were Eastern Cooperative Oncology Group 0, and the median tumor size was 2.7 cm (range: 1-8) according to blinded, independent, central review. Radioembolization served as neoadjuvant therapy for transplantation or resection in 21.0% (34 of 162) and 6.8% (11 of 162) of patients, respectively, and as primary treatment for all others. Median follow-up time was 29.9 months by reverse Kaplan-Meier. ORR (best response) was 88.3% (CI: 82.4-92.4), with 62.2% (CI: 54.1-69.8) exhibiting a DoR ≥ 6 months. Three-year overall survival was 86.6% for all patients and 92.8% for those neoadjuvant patients with resected or transplanted liver. CONCLUSIONS: In this multicenter study of radioembolization, clinical meaningful response rates and prolonged DoR were observed in the treatment of unresectable, solitary HCC ≤ 8 cm.

Radioembolization Plus Chemotherapy for First-line Treatment of Locally Advanced Intrahepatic Cholangiocarcinoma: A Phase 2 Clinical Trial.

IMPORTANCE: Patients with unresectable intrahepatic cholangiocarcinoma (ICC) have a poor prognosis. Selective internal radiotherapy (SIRT) is a promising treatment option for hepatic tumors, but no prospective studies of combination SIRT with chemotherapy have been published to our knowledge. OBJECTIVE: To determine the response rate after SIRT combined with chemotherapy in patients with unresectable ICC. DESIGN, SETTING, AND PARTICIPANTS: This phase 2 clinical trial, the Yttrium-90 Microspheres in Cholangiocarcinoma (MISPHEC) trial, included patients with unresectable ICC who have never received chemotherapy or intra-arterial therapy and were treated at 7 centers which had experience with SIRT between November 12, 2013, and June 21, 2016. Statistical analysis was performed from March 31, 2017, to June 17, 2019. INTERVENTIONS: Concomitant first-line chemotherapy with cisplatin, 25 mg/m2, and gemcitabine, 1000 mg/m2 (gemcitabine reduced to 300 mg/m2 for the cycles just before and after SIRT), on days 1 and 8 of a 21-day cycle for 8 cycles. Selective internal radiotherapy was administered during cycle 1 (1 hemiliver disease) or cycles 1 and 3 (disease involving both hemilivers) using glass Y90 microspheres. MAIN OUTCOMES AND MEASURES: Response rate at 3 months according to Response Evaluation Criteria in Solid Tumors (RECIST) 1.1. Secondary end points were toxic effects, progression-free survival, overall survival, disease control rate, and response rate according to Choi criteria. RESULTS: Of 41 patients included in the study, 26 (63%) were male, with a mean (SD) age of 64.0 (10.7) years. Response rate according to RECIST was 39% (90% CI, 26%-53%) at 3 months according to local review and was confirmed at 41% as best response by central review; disease control rate was 98%. According to Choi criteria, the response rate was 93%. After a median follow-up of 36 months (95% CI, 26-52 months), median progression-free survival was 14 months (95% CI, 8-17 months), with progression-free survival rates of 55% at 12 months and 30% at 24 months. Median overall survival was 22 months (95% CI, 14-52 months), with overall survival rates of 75% at 12 months and 45% at 24 months. Of 41 patients, 29 (71%) had grades 3 to 4 toxic effects; 9 patients (22%) could be downstaged to surgical intervention, with 8 (20%) achieving R0 (microscopic-free margins) surgical resection. After a median of 46 months (95% CI, 31 months to not reached) after surgery, median relapse-free survival was not reached among patients who underwent resection. CONCLUSIONS AND RELEVANCE: Combination chemotherapy and SIRT had antitumor activity as first-line treatment of unresectable ICC, and a significant proportion of patients were downstaged to surgical intervention. A phase 3 trial is ongoing.

VEROnA Protocol: A Pilot, Open-Label, Single-Arm, Phase 0, Window-of-Opportunity Study of Vandetanib-Eluting Radiopaque Embolic Beads (BTG-002814) in Patients With Resectable Liver Malignancies.

BACKGROUND: Transarterial chemoembolization (TACE) is the current standard of care for patients with intermediate-stage hepatocellular carcinoma (HCC) and is also a treatment option for patients with liver metastases from colorectal cancer. However, TACE is not a curative treatment, and tumor progression occurs in more than half of the patients treated. Despite advances and technical refinements of TACE, including the introduction of drug-eluting beads-TACE, the clinical efficacy of TACE has not been optimized, and improved arterial therapies are required. OBJECTIVE: The primary objectives of the VEROnA study are to evaluate the safety and tolerability of vandetanib-eluting radiopaque embolic beads (BTG-002814) in patients with resectable liver malignancies and to determine concentrations of vandetanib and the N-desmethyl metabolite in plasma and resected liver following treatment with BTG-002814. METHODS: The VEROnA study is a first-in-human, open-label, single-arm, phase 0, window-of-opportunity study of BTG-002814 (containing 100 mg vandetanib) delivered transarterially, 7 to 21 days before surgery in patients with resectable liver malignancies. Eligible patients have a diagnosis of colorectal liver metastases, or HCC (Childs Pugh A), diagnosed histologically or radiologically, and are candidates for liver surgery. All patients are followed up for 28 days following surgery. Secondary objectives of this study are to evaluate the anatomical distribution of BTG-002814 on noncontrast-enhanced imaging, to evaluate histopathological features in the surgical specimen, and to assess changes in blood flow on dynamic contrast-enhanced magnetic resonance imaging following treatment with BTG-002814. Exploratory objectives of this study are to study blood biomarkers with the potential to identify patients likely to respond to treatment and to correlate the distribution of BTG-002814 on imaging with pathology by 3-dimensional modeling. RESULTS: Enrollment for the study was completed in February 2019. Results of a planned interim analysis were reviewed by a safety committee after the first 3 patients completed follow-up. The recommendation of the committee was to continue the study without any changes to the dose or trial design, as there were no significant unexpected toxicities related to BTG-002814. CONCLUSIONS: The VEROnA study is studying the feasibility of administering BTG-002814 to optimize the use of this novel technology as liver-directed therapy for patients with primary and secondary liver cancer.

Quantitative evaluation of liver metastases density on computed tomography: A new tool to evaluate early response to bevacizumab-containing chemotherapy.

BACKGROUND: Response Evaluation Criteria in Solid Tumors (RECIST) are used to assess tumour shrinkage after cytotoxic chemotherapy, but may be inadequate for efficacy evaluation of anti-angiogenic therapies. AIMS: This study aimed to identify novel radiologic tumour response criteria based on early changes in tumour size and density, observed on computed tomography (CT), in patients with colorectal liver metastases (CRLM) treated with bevacizumab-containing chemotherapy. METHODS: CT of 71 and 68 CRLM patients treated with bevacizumab and non-bevacizumab-based regimens, respectively, were retrospectively reviewed. Tumour size, tumour density, and tumour-to-liver density (TTLD) ratio were determined at baseline and at first restaging. We tested their correlation with progression-free (PFS) and overall survival (OS) using the log-rank test. RESULTS: In the bevacizumab group, neither RECIST response nor tumour density variation was correlated with PFS or OS. In contrast, PFS and OS were significantly longer in patients with tumour size reduction ≥15% (RECIST-15%) and/or decrease in TTLD ratio not exceeding -10% (TTLD-10%) than in patients who did not reach any of those criteria, in univariate and multivariate analysis. Only size-response criteria predicted clinical outcome in the non-bevacizumab group. CONCLUSIONS: This study highlights new quantitative CT criteria that may early predict the efficacy of bevacizumab in CRLM patients.

Gemcitabine and Oxaliplatin Chemotherapy or Surveillance in Resected Biliary Tract Cancer (PRODIGE 12-ACCORD 18-UNICANCER GI): A Randomized Phase III Study.

PURPOSE: No standard adjuvant treatment currently is recommended in localized biliary tract cancer (BTC) after surgical resection. We aimed to assess whether gemcitabine and oxaliplatin chemotherapy (GEMOX) would increase relapse-free survival (RFS) while maintaining health-related quality of life (HRQOL) in patients who undergo resection. PATIENTS AND METHODS: We performed a multicenter, open-label, randomized phase III trial in 33 centers. Patients were randomly assigned (1:1) within 3 months after R0 or R1 resection of a localized BTC to receive either GEMOX (gemcitabine 1,000 mg/m2 on day 1 and oxaliplatin 85 mg/m2 infused on day 2 of a 2-week cycle) for 12 cycles (experimental arm A) or surveillance (standard arm B). Primary end points were RFS and HRQOL. RESULTS: Between July 2009 and February 2014, 196 patients were included. Baseline characteristics were balanced between the two arms. After a median follow-up of 46.5 months (95% CI, 42.6 to 49.3 months), 126 RFS events and 82 deaths were recorded. There was no significant difference in RFS between the two arms (median, 30.4 months in arm A v 18.5 months in arm B; hazard ratio [HR], 0.88; 95% CI, 0.62 to 1.25; P = .48). There was no difference in time to definitive deterioration of global HRQOL (median, 31.8 months in arm A v 32.1 months in arm B; HR, 1.28; 95% CI, 0.73 to 2.26; log-rank P = .39). Overall survival was not different (median, 75.8 months in arm A v 50.8 months in arm B; HR, 1.08; 95% CI, 0.70 to 1.66; log-rank P = .74). Maximal adverse events were grade 3 in 62% (arm A) versus 18% (arm B) and grade 4 in 11% versus 3% ( P < .001). CONCLUSION: There was no benefit of adjuvant GEMOX in resected BTC despite adequate tolerance and delivery of the regimen.

TheraSphere Yttrium-90 Glass Microspheres Combined With Chemotherapy Versus Chemotherapy Alone in Second-Line Treatment of Patients With Metastatic Colorectal Carcinoma of the Liver: Protocol for the EPOCH Phase 3 Randomized Clinical Trial.

BACKGROUND: Colorectal cancer is one of the most common cancers and causes of cancer-related death. Up to approximately 70% of patients with metastatic colorectal cancer (mCRC) have metastases to the liver at initial diagnosis. Second-line systemic treatment in mCRC can prolong survival after development of disease progression during or after first-line treatment and in those who are intolerant to first-line treatment. OBJECTIVE: The objective of this study is to evaluate the efficacy and safety of transarterial radioembolization (TARE) with TheraSphere yttrium-90 (90Y) glass microspheres combined with second-line therapy in patients with mCRC of the liver who had disease progression during or after first-line chemotherapy. METHODS: EPOCH is an open-label, prospective, multicenter, randomized, phase 3 trial being conducted at up to 100 sites in the United States, Canada, Europe, and Asia. Eligible patients have mCRC of the liver and disease progression after first-line chemotherapy with either an oxaliplatin-based or irinotecan-based regimen and are eligible for second-line chemotherapy with the alternate regimen. Patients were randomized 1:1 to the TARE group (chemotherapy with TARE in place of the second chemotherapy infusion and subsequent resumption of chemotherapy) or the control group (chemotherapy alone). The addition of targeted agents is permitted. The primary end points are progression-free survival and hepatic progression-free survival. The study objective will be considered achieved if at least one primary end point is statistically significant. Secondary end points are overall survival, time to symptomatic progression defined as Eastern Cooperative Oncology Group Performance Status score of 2 or higher, objective response rate, disease control rate, quality-of-life assessment by the Functional Assessment of Cancer Therapy-Colorectal Cancer questionnaire, and adverse events. The study is an adaptive trial, comprising a group sequential design with 2 interim analyses with a planned maximum of 420 patients. The study is designed to detect a 2.5-month increase in median progression-free survival, from 6 months in the control group to 8.5 months in the TARE group (hazard ratio [HR] 0.71), and a 3.5-month increase in median hepatic progression-free survival time, from 6.5 months in the control group to 10 months in the TARE group (HR 0.65). On the basis of simulations, the power to detect the target difference in either progression-free survival or hepatic progression-free survival is >90%, and the power to detect the target difference in each end point alone is >80%. RESULTS: Patient enrollment ended in October 2018. The first interim analysis in June 2018 resulted in continuation of the study without any changes. CONCLUSIONS: The EPOCH study may contribute toward the establishment of the role of combination therapy with TARE and oxaliplatin- or irinotecan-based chemotherapy in the second-line treatment of mCRC of the liver.

Intra-Arterial TheraSphere Yttrium-90 Glass Microspheres in the Treatment of Patients With Unresectable Hepatocellular Carcinoma: Protocol for the STOP-HCC Phase 3 Randomized Controlled Trial.

BACKGROUND: Globally, hepatocellular carcinoma is the second most common cause of cancer deaths. It remains challenging to intensify cancer treatment without impairing liver function. OBJECTIVE: The objective of the TheraSphere in the Treatment of Patients with Unresectable Hepatocellular Carcinoma (STOP-HCC) study is to examine the hypothesis that transarterial radioembolization (TheraSphere yttrium-90 glass microspheres) combined with standard first-line treatment with sorafenib will improve outcomes over treatment with sorafenib alone in unresectable hepatocellular carcinoma. The STOP-HCC study is the largest international, multicenter, prospective study of intra-arterial treatment in combination with sorafenib in unresectable hepatocellular carcinoma. Here we report the study design. METHODS: STOP-HCC is a prospective, phase 3, open-label, randomized controlled study conducted across up to 105 sites in North America, Europe, and Asia. Eligible adults have unresectable hepatocellular carcinoma and a life expectancy of at least 12 weeks, 1 or more unidimensional measurable lesions, Child-Pugh score 7 points or less, and Eastern Cooperative Oncology Group Performance Status score 1 or lower, and are candidates for treatment with sorafenib. Presence of branch portal vein tumor thrombosis is permitted. Patients were randomly assigned in a 1:1 ratio to receive either sorafenib alone or transarterial radioembolization followed by sorafenib within 2 to 6 weeks. The primary outcome is overall survival. Secondary outcomes are time to progression, time to untreatable progression, time to symptomatic progression, tumor response, quality of life, and adverse event occurrence. The study is an adaptive trial, comprising a group-sequential design with 2 interim analyses with 520 patients, and an option to increase the sample size to 700 patients at the second interim analysis. The sample size of 520 patients allows for 417 deaths to give 80% power to detect an increase in median overall survival from 10.7 months for the sorafenib group (based on the Sorafenib Hepatocellular Carcinoma Assessment Randomized Protocol [SHARP] trial) to 14.2 months for the transarterial radioembolization+sorafenib group (hazard ratio 0.754) with 2-sided alpha of .05. The increased sample size of 700 patients allows for 564 deaths to give 80% power to detect a smaller difference in median overall survival from 10.7 months for the sorafenib group to 13.7 months for the transarterial radioembolization+sorafenib group (hazard ratio 0.781). RESULTS: Enrollment for the study completed in September 2017. Results of the first and second interim analyses were reviewed by the Independent Data Monitoring Committee. The recommendation of the committee, at both interim analyses, was to continue the study without any changes. CONCLUSIONS: The STOP-HCC study will contribute toward the establishment of the role of combination therapy with transarterial radioembolization and sorafenib in the treatment of unresectable hepatocellular carcinoma with and without branch portal vein tumor thrombosis.

Implementation of a Nurse-driven Educational Program Improves Management of Sorafenib's Toxicities in Hepatocellular Carcinoma.

BACKGROUND: Sorafenib is the standard treatment of advanced hepatocellular carcinoma. Because of its unique toxicities, improving patients' tolerance merits close follow-up. Nurses can play a crucial role by leading a patient educational program (EP). OBJECTIVES: The aim of this study was to assess whether adding EP to usual care (UC) improves patient's care. METHODS: Since 2011, oncologists referred patients treated by sorafenib to the EP led by clinical nurses. The EP included a visit before the first administration, weekly telephone calls, and a visit with the nurse before each oncologist consultation. We retrospectively compared patients in the EP with those in UC followed by an oncologist and patients included in a clinical trial. RESULTS: Since 2005, 129 patients were treated with sorafenib for hepatocellular carcinoma: 31 in the EP (24%), 22 in a clinical trial (17%), and 76 with UC (59%). Seventy-one percent of the patients in the EP had toxicities identified during a telephone call, which prompted symptomatic measures in 65% of the patients, leading to treatment modification before the planned on-site visit in 29% of the patients. Educational program patients required fewer dose reductions (39% vs 61% for UC, P = .04), and median time to first dose reduction was shorter with EP than with UC (25 vs 45 days, P = .036). CONCLUSIONS: This study suggests a clinical benefit of EP related to improved toxicity management of sorafenib that resulted in fewer dose reductions. IMPLICATIONS FOR PRACTICE: Patients treated with sorafenib may benefit from an EP. Different types of EP should be compared prospectively, focusing on patients' quality of life.

[Implementation of a nurse-driven educational program improves management of sorafenib's toxicities in hepatocellular carcinoma]. / Les infirmières cliniciennes améliorent la gestion des toxicités des patients traités par sorafénib pour carcinome hépatocellulaire.

BACKGROUND: Sorafenib is the standard treatment for advanced hepatocellular carcinoma (HCC). Due to its peculiar toxicities, improving patient's tolerance may need close follow-up. Nurses can play a crucial role, by driving a patient education program (EP). We aimed to prove that adding EP to usual care (UC) improves patient's care. METHODS: Since 2011, oncologists referred patients treated by sorafenib to the EP, driven by clinical nurses. It consisted in a visit before first administration, weekly telephone calls and a visit before each oncologist consultation. We retrospectively compared patients followed by the EP to those followed by oncologist in usual care (UC) and patients included in a clinical trial (CT). RESULTS: Since 2005, 129 patients were treated with sorafenib for HCC, 31 (24%) in the EP, 22 (17%) in CT and 76 (59%) with UC. Seventy-one percent of patients in the EP had toxicities identified during a telephone call, which prompted symptomatic measures in 65% of patients, leading to treatment modification before the planned on-site visit in 29% of patients. EP patients required less dose reductions (39% vs. 61% for UC, P=0.04), and median time to first dose reduction was shorter with EP than with UC (25 days vs. 45 days, P=0.036). CONCLUSION: This study suggests a clinical benefit of EP, with a better toxicity's management of sorafenib, leading to less dose reduction. Different types of EP should be compared prospectively, focusing on quality of life.

SIRFLOX: Randomized Phase III Trial Comparing First-Line mFOLFOX6 (Plus or Minus Bevacizumab) Versus mFOLFOX6 (Plus or Minus Bevacizumab) Plus Selective Internal Radiation Therapy in Patients With Metastatic Colorectal Cancer.

PURPOSE: SIRFLOX was a randomized, multicenter trial designed to assess the efficacy and safety of adding selective internal radiation therapy (SIRT) using yttrium-90 resin microspheres to standard fluorouracil, leucovorin, and oxaliplatin (FOLFOX)-based chemotherapy in patients with previously untreated metastatic colorectal cancer. PATIENTS AND METHODS: Chemotherapy-naïve patients with liver metastases plus or minus limited extrahepatic metastases were randomly assigned to receive either modified FOLFOX (mFOLFOX6; control) or mFOLFOX6 plus SIRT (SIRT) plus or minus bevacizumab. The primary end point was progression-free survival (PFS) at any site as assessed by independent centralized radiology review blinded to study arm. RESULTS: Between October 2006 and April 2013, 530 patients were randomly assigned to treatment (control, 263; SIRT, 267). Median PFS at any site was 10.2 v 10.7 months in control versus SIRT (hazard ratio, 0.93; 95% CI, 0.77 to 1.12; P = .43). Median PFS in the liver by competing risk analysis was 12.6 v 20.5 months in control versus SIRT (hazard ratio, 0.69; 95% CI, 0.55 to 0.90; P = .002). Objective response rates (ORRs) at any site were similar (68.1% v 76.4% in control v SIRT; P = .113). ORR in the liver was improved with the addition of SIRT (68.8% v 78.7% in control v SIRT; P = .042). Grade ≥ 3 adverse events, including recognized SIRT-related effects, were reported in 73.4% and 85.4% of patients in control versus SIRT. CONCLUSION: The addition of SIRT to FOLFOX-based first-line chemotherapy in patients with liver-dominant or liver-only metastatic colorectal cancer did not improve PFS at any site but significantly delayed disease progression in the liver. The safety profile was as expected and was consistent with previous studies.

Feasibility of Capecitabine and Oxaliplatin Combination Chemotherapy Without Central Venous Access Device in Patients With Stage III Colorectal Cancer.

BACKGROUND: 5-Fluorouracil and leucovorin plus oxaliplatin (FOLFOX) or capecitabine plus oxaliplatin (XELOX) is a standard adjuvant treatment for patients with stage III colon cancer (CC). Capecitabine is an oral fluoropyrimidine, and administration of oxaliplatin does not necessarily require the insertion of a central venous access device (CVAD). We evaluated the feasibility of XELOX without a CVAD as adjuvant treatment in patients with stage III CC. PATIENTS AND METHODS: We retrospectively studied prospectively collected data from patients with stage III CC treated with XELOX in the International Duration Evaluation of Adjuvant Chemotherapy French trial. Patients were divided into 2 groups: those with a CVAD and those with peripheral venous access (PVA), including patients who had and had not had a CVAD at the first cycle of chemotherapy. Chemotherapy without a CVAD was considered feasible if the patient received all cycles of adjuvant therapy without it. RESULTS: A total of 203 patients were included: 86 (43%) in the PVA group and 116 (57%) in the CVAD group. Of the 85 patients in the PVA group (1 patient was not treated), 69 (81.2%) did not require the insertion of a CVAD. However, 16 (18.8%) required CVAD insertion owing to systematic delay of the initially planned CVAD before the second cycle of chemotherapy in 7, complications related to PVA usage in 5, a switch to the modified FOLFOX6 regimen in 2, and other reasons in 2. The oxaliplatin dose was similar in both groups regardless of the chemotherapy duration. XELOX without a CVAD was feasible for 81.2% of the patients for whom a CVAD had not been planned before chemotherapy and for 88.4% of patients for whom chemotherapy was planned without the use of a CVAD. CONCLUSION: XELOX chemotherapy without a CVAD is a feasible approach for treating patients with stage III CC in the adjuvant setting.

Selective internal radiation therapy compared with sorafenib for hepatocellular carcinoma with portal vein thrombosis.

PURPOSE: Tumoural portal vein thrombosis (PVT) is a major prognostic factor in hepatocellular carcinoma (HCC). The efficacy of sorafenib, the only treatment approved at an advanced stage, is limited. Based on previous data, selective internal radiation therapy (SIRT), or (90)Y radioembolization, seems an interesting option. We aimed to compare both treatments in this population. METHODS: We retrospectively compared patients treated in two centres for HCC with tumoural PVT. We compared overall survival (OS) between patients treated with SIRT and patients treated with sorafenib. Analyses were performed before and after 1:1 matching with a propensity score for controlling indication bias, using a Cox proportional hazards model. RESULTS: A total of 151 patients were analysed, 34 patients treated with SIRT and 117 patients treated with sorafenib only. In the whole population, SIRT was associated with a higher median OS as compared with sorafenib: 18.8 vs 6.5 months (log-rank p < 0.001). There was an imbalance of baseline characteristics between patients treated by SIRT and sorafenib, which justified patient matching with use of a propensity score: 24 patients treated with SIRT could be matched with 24 patients treated with sorafenib. OS was estimated with a median of 26.2 vs 8.7 months in patients treated with SIRT vs sorafenib, respectively (log-rank p = 0.054). Before and after patient matching, the adjusted hazard ratio related to treatment by SIRT was estimated at 0.62 [95 % confidence interval (CI) 0.39-0.97] (p = 0.037) and 0.40 (95 % CI 0.19-0.82) (p = 0.013), respectively. CONCLUSION: SIRT seems more effective than sorafenib in patients presenting with HCC and tumoural PVT. This hypothesis is being tested in prospective randomized trials.

Glass Microspheres 90Y Selective Internal Radiation Therapy and Chemotherapy as First-Line Treatment of Intrahepatic Cholangiocarcinoma.

PURPOSE OF THE REPORT: Intrahepatic cholangiocarcinoma's incidence is increasing. We studied the efficacy of Y selective internal radiation therapy (SIRT) as first-line treatment, with chemotherapy, and compared with the results of chemotherapy alone. PATIENTS AND METHODS: We retrospectively studied data from patients treated at our institution with glass microspheres SIRT for intrahepatic cholangiocarcinoma as part of first-line treatment in combination with chemotherapy. We compared results with those of similar patients treated in the ABC-02 study (a study in advanced biliary tract cancer that defined the current standard chemotherapy), assessed as not progressing after the first evaluation. We assessed progression-free survival (PFS) and overall survival (OS). RESULTS: Twenty-four patients were treated with SIRT. Chemotherapy was given concomitantly in 10 (42%), as induction before SIRT in 13 (54%) or after SIRT in 1 (4%). Grade 3 adverse events were reported in 1 (4%). Median PFS after SIRT was 10.3 months. Longer PFS was observed when chemotherapy was given concomitantly than when chemotherapy was given before SIRT, with respective median of 20.0 versus 8.8 months (P = 0.001). Median OS after SIRT was not reached. Eleven patients went to surgery (46%). Thirty-three patients in ABC-02 had locally advanced nonextrahepatic cholangiocarcinoma, not progressing after first evaluation. From the start of any treatment, the median PFS was 16.0 months in our cohort versus 11.3 months in ABC-02 (P = 0.25), whereas the median OS was significantly higher in our cohort, not reached versus 17.9 months, respectively (P = 0.026). CONCLUSIONS: Selective internal radiation therapy combined with concomitant chemotherapy seems a promising strategy as first-line treatment for unresectable intrahepatic cholangiocarcinoma.

Yttrium-90 microsphere radioembolization for hepatocellular carcinoma.

Yttrium-90 (Y90) radioembolization is an emerging strategy to treat liver malignancies, and clinical data supporting its use have accumulated in recent years. Y90-radioembolization has shown clinical effectiveness in intermediate and advanced hepatocellular carcinoma, with a favorable safety profile. Retrospective data show similar levels of effectiveness to transarterial chemoembolization in intermediate hepatocellular carcinoma, with some evidence of better tolerance. While phase 3 studies comparing Y90-radioembolization to chemoembolization in intermediate hepatocellular carcinoma would be difficult to conduct, studies comparing or combining Y90-radioembolization with sorafenib are under way. Questions also remain about the most suitable modalities for defining the dose to administer. Phase 3 studies are under way to clarify the place of Y90-radioembolization in the algorithm of HCC treatment.

Randomized trial of TAS-102 for refractory metastatic colorectal cancer.

BACKGROUND: Early clinical trials conducted primarily in Japan have shown that TAS-102, an oral agent that combines trifluridine and tipiracil hydrochloride, was effective in the treatment of refractory colorectal cancer. We conducted a phase 3 trial to further assess the efficacy and safety of TAS-102 in a global population of such patients. METHODS: In this double-blind study, we randomly assigned 800 patients, in a 2:1 ratio, to receive TAS-102 or placebo. The primary end point was overall survival. RESULTS: The median overall survival improved from 5.3 months with placebo to 7.1 months with TAS-102, and the hazard ratio for death in the TAS-102 group versus the placebo group was 0.68 (95% confidence interval [CI], 0.58 to 0.81; P<0.001). The most frequently observed clinically significant adverse events associated with TAS-102 were neutropenia, which occurred in 38% of those treated, and leukopenia, which occurred in 21%; 4% of the patients who received TAS-102 had febrile neutropenia, and one death related to TAS-102 was reported. The median time to worsening performance status (a change in Eastern Cooperative Oncology Group performance status [on a scale of 0 to 5, with 0 indicating no symptoms and higher numbers indicating increasing degrees of disability] from 0 or 1 to 2 or more) was 5.7 months with TAS-102 versus 4.0 months with placebo (hazard ratio, 0.66; 95% CI, 0.56 to 0.78; P<0.001). CONCLUSIONS: In patients with refractory colorectal cancer, TAS-102, as compared with placebo, was associated with a significant improvement in overall survival.

Extended liver resections for intrahepatic cholangiocarcinoma: friend or foe?

BACKGROUND: In patients with intrahepatic cholangiocarcinoma (ICC), extended liver resections (ELRs) increase the rate of resectability. The aims of the present study were to evaluate the morbidity and oncologic outcomes of ELR compared with other liver resections (LR) for ICC. METHODS: All LR for ICC that were performed in our center between January 1997 and September 2013 and conducted with curative intent were included in this retrospective analysis. ELRs were defined by resections of ≥5 liver segments. The factors that influenced the occurrence of major complications (Clavien ≥ 3) and overall survival (OS) were tested with univariate and multivariate analyses. RESULTS: One hundred seven patients (82 men and 25 women) were resected, and 27 (25.3%) underwent ELRs. Compared with the LRs, the ELRs were performed in larger tumors (P = .003) and were significantly associated with more complex surgeries such as vascular (P < .001) or biliary reconstructions (P < .001). Multivariate analysis revealed that ELR was an independent risk factor for major complications (odds ratio [OR], 6.2; 95% CI, 2.11-19.62; P < .001). Compared with the other LRs, ELRs had no effects on OS or disease-free survival (P = .881 and P = .228, respectively). Perioperative blood transfusion (Hazard ratio (HR), 2.51; 95% CI, 1.49-4.23; P < .001), the presence of >1 nodule (HR, 3.17; 95% CI, 1.67-5.97; P < .001), and age ≥65 years (HR, 1.72; 95% CI, 1.03-2.86; P = .036) were independent prognostic factors for OS. CONCLUSION: This study suggests that ELRs performed for large ICCs do not affect negatively oncologic outcomes, despite the increased risk of major complications.
