AbstractThe liver is the most common site of metastatic disease in colorectal cancer, and, in the setting of liver-dominant disease, a chief contributor to mortality. Chemotherapy is the backbone of treatment for metastatic colorectal cancer; however, the duration of response is limited and resistance to therapy inevitably develops. Radioembolization represents a targeted treatment to the liver which has been studied in first-line, second-line, and in salvage treatment. Therapeutic rationale, outcomes, and prognostic indicators are presented in this systematic review article.

4094 Background: We have previously shown that capecitabine/irinotecan (XELIRI) is effective and well-tolerated in metastatic colorectal cancer (mCRC). Cetuximab, a monoclonal IgG1 antibody that binds to the extracellular domain of EGFR, is active in mCRC alone or in combination with chemotherapy. This study was designed to evaluate if cetuximab (Erbitux®) added to XELIRI improves outcome in first-line treatment of mCRC. Methods: Subjects had histologically confirmed colorectal adenocarcinoma with T4 lesions that were unresectable after preoperative chemoradiation therapy and/or metastases. The study regimen was capecitabine 1700 mg/m2 (850 mg/m2 PO BID Days 1–14), irinotecan 200 mg/m2 IV Day 1 every 3 weeks, and weekly cetuximab (initial dose 400 mg/m2 IV over 120 minutes, subsequent doses 250 mg/m2 over 30 minutes). Results: Between February and October 2005, 70 subjects enrolled. Baseline characteristics: 43 males (61%), median age 61.5 years, and ECOG PS 0/1= 66%/34%; 94% of subjects had adenocarcinoma. Prior therapy; surgery (91%), chemotherapy (20%), or radiotherapy (7%). Responses (pts >2 cycles) were; CR (4%), PR (36%), SD (40%) and PD (20%); 15 patients failed treatment; (n=4 allergic reaction, n=2 MD request, n=2 withdrew consent, n=2 Grade 4 neutropenia, and n=5 other AEs). The overall response rate was 40% and the disease control rate was 80%. Median duration of response was 8.8 months (range, 2.6–15.1) and median time to response was 2.0 months (range, 1.2–8.3). 64% of patients remain alive; of the 25 deaths, 84% were due to PD. No death was drug related. The most frequent Grade 3 and 4 treatment-related adverse events (AEs) included: diarrhea (25%), neutropenia (18%), nausea/vomiting (12%), rash and dehydration (9%, each), HFS and fatigue (7%), and allergic reaction (6%). 54% of patients required dose reductions. To date, 64 patients (91%) have gone off study, primarily due to PD (39%) or AE (33%); 3 patients remain on treatment. Conclusions: The combination of cetuximab and XELIRI is feasible and tolerable in first line mCRC. Toxicities are expected and manageable with dose reductions/delay.

Significant Difference

Background: Pre-treated patients with first-line treatment can be offered a second treatment with the aim of improving their poor clinical prognosis. The therapy of metastatic colorectal cancer (CRC) patients who did not respond to first-line therapy has limited treatment options. Recently, many studies have paid much attention to the efficacy of bevacizumab as an adjuvant treatment for metastatic colorectal cancer. Objectives: We aimed to evaluate the efficacy and toxicity of bevacizumab plus chemotherapy compared with bevacizumab-naive based chemotherapy as second-line treatment in people with metastatic CRC. Methods: Electronic databases were searched for eligible studies updated to March 2018. Randomized-controlled trials comparing addition of bevacizumab to chemotherapy without bevacizumab in MCRC patients were included, of which, the main interesting results were the efficacy and safety profiles of the addition of bevacizumab in patients with MCRC as second-line therapy. Result: Five trials were eligible in the meta-analysis. Patients who received the combined bevacizumab and chemotherapy treatment in MCRC as second-line therapy showed a longer overall survival (OS) (OR=0.80,95%CI=0.72-0.89, P<0.0001) and progression-free survival (PFS) (OR=0.69,95%CI=0.61-0.77, P<0.00001). In addition, there was no significant difference in objective response rate (ORR) (RR=1.36,95%CI=0.82-2.24, P=0.23) or severe adverse event (SAE) (RR=1.02,95%CI=0.88-1.19, P=0.78) between bevacizumab-based chemotherapy and bevacizumabnaive based chemotherapy. Conclusion: Our results suggest that the addition of bevacizumab to the chemotherapy therapy could be an efficient and safe treatment option for patients with metastatic colorectal cancer as second-line therapy and without increasing the risk of an adverse event.

First Line Treatment

Target-oriented agents improve metastatic colorectal cancer (mCRC) survival in combination with chemotherapy. However, the majority of patients experience disease progression after first-line treatment and are eligible for second-line approaches. In such a context, antiangiogenic and anti-Epidermal Growth Factor Receptor (EGFR) agents as well as immune checkpoint inhibitors have been approved as second-line options, and RAS and BRAF mutations and microsatellite status represent the molecular drivers that guide therapeutic choices. Patients harboring K- and N-RAS mutations are not eligible for anti-EGFR treatments, and bevacizumab is the only antiangiogenic agent that improves survival in combination with chemotherapy in first-line, regardless of RAS mutational status. Thus, the choice of an appropriate therapy after the progression to a bevacizumab or an EGFR-based first-line treatment should be evaluated according to the patient and disease characteristics and treatment aims. The continuation of bevacizumab beyond progression or its substitution with another anti-angiogenic agents has been shown to increase survival, whereas anti-EGFR monoclonals represent an option in RAS wild-type patients. In addition, specific molecular subgroups, such as BRAF-mutated and Microsatellite Instability-High (MSI-H) mCRCs represent aggressive malignancies that are poorly responsive to standard therapies and deserve targeted approaches. This review provides a critical overview about the state of the art in mCRC second-line treatment and discusses sequential strategies according to key molecular biomarkers.
