Aims: Bevacizumab (B) in association with systemic chemotherapy is commonly used for the treatment of colorectal cancer liver metastases. The aim of this study was to monitor tumor response, overall survival (OS) and progression-free survival (PFS) of patients with colorectal cancer liver metastases treated with transarterial chemoembolization (TACE) + B compared with TACE alone and to correlate the results with KRAS mutational status. Patients & methods: This was an observational multicentric case–control study (NCT03732235) on the efficacy and safety of B administered after TACE. Results: The disease control rate was significantly higher for the TACE + B than the TACE alone group (p < 0.001). KRAS wild-type patients had a significantly better disease control rate than those with KRAS mutations in the TACE + B group. Median OS and PFS were similar for the TACE + B and TACE groups, whereas median time to progression was significantly higher for the TACE + B group (p < 0.01). Conclusion: The combination of TACE with B may improve tumor response and delay disease progression.

The Impact

770 Background: The use of selective internal radiation therapy (SIRT) with SIR-Spheres in chemotherapy-resistant colorectal cancer liver metastases (CRC-L) has been associated with favorable progression free survival (PFS) and overall survival (OS) when given alone or concurrently with chemotherapy. However, no prospective studies exist for concurrent SIRT and chemotherapy (SIRT-CT) vs. SIRT alone. We conducted a single institute retrospective trial to compare the effect of SIRT-CT to SIRT alone on liver PFS in patients with CRC-L. Methods: Patients (pts) with CRC-L treated with SIR-Spheres at City of Hope between 2009 and 2014 were identified. CRL-L patients treated with SIRT-CT or with SIRT were excluded if they received, following radioembolization, any chemotherapy/targeted regimen on which they did not previously progress. This strategy was adopted to minimize the impact of post-SIRT systemic therapy bias on SIRT-CT/SIRT liver PFS outcome. Pts characteristics included demographics, liver involvement pattern, and lines of prior chemotherapy. Liver PFS, response rate, and toxicities were compared between SIRT-CT and SIRT arms. Kaplan-Meier estimation was used for PFS analysis. Results: 48 CRC-L pts were treated with SIR-spheres; 27 satisfied the post-SIR-spheres systemic treatment criteria (14 SIRT-CT, 13 SIRT) and were included on this study. Pts characteristics included: age (median = 62; range 52-80), sex (18 males), primary site (colon: 23), hepatic disease burden (23 bilobar), 5-FU resistance/intolerance (25/2), and extrahepatic disease (22). Pts characteristics were similar between treatment arms, except for median prior therapies (SIRT-CT = 3, SIRT = 2). No SIRT-CT or SIRT associated ≥ grade 3 toxicities were noted. Disease control rates were 84% (2/13 PR; 9/13 SD) and 14% (2/14 SD on the SIRT-CT and SIRT arms, respectively (p = 0.001). Median PFS in the liver was 176 days in the SIRT-CT group vs. 91 days in the SIRT group (p = 0.0006). Conclusions: In patients with 5-FU refractory CRC-L, SIRT-CT is associated with an increased disease control rate and a prolonged DFS in comparison with SIRT alone.

e15585 Background: A previous phase 1b trial has shown encouraging efficacy of regorafenib plus nivolumab in patients with microsatellite stable/mismatch repair proficient (MSS/pMMR) metastatic colorectal cancer (mCRC). We aimed to evaluate the efficacy and safety of this regimen in Chinese patients in the real world. Methods: We retrospectively identified patients with MSS/pMMR mCRC who received at least one dose of programmed cell death-1 (PD-1) inhibitors plus regorafenib from 5/2019 to 2/2021 in 10 Chinese medical centers. The primary endpoint was overall survival (OS). Secondary endpoints included progression-free survival (PFS), objective response rate (ORR), disease control rate (DCR) and the safety. Results: Fifty-two patients were identified. Liver metastases were presented in 35 patients (67%). A total of 48 patients (92%) received regorafenib plus a PD-1 inhibitor as the third or later line treatment. At the data cut-off, 11 patients (21%) were still on treatment. Other patients terminated treatment because of progressive disease (45%), treatment-related adverse events (TRAEs) (14%) or treatment-unrelated deaths (6%). The median treatment cycle was 3 (range, 1-18). At a median follow-up of 4.9 months, the median OS was 17.3 months (95% CI, 10.2-NR) and the median PFS was 3.1 months (95%CI, 2.5-6.0). Baseline liver metastases were associated with inferior PFS (2.7 versus 6.3 months, p <0.05), but not OS (17.3 months versus NR, p =0.6). Among 38 patients evaluable for response, two patients (5%) achieved partial response, and 17 patients (45%) experienced stable disease as the best response. The DCR was 50% (95%CI, 5.0-NR) and was similar among different PD-1 inhibitors (Table). TRAEs were observed in 30 patients (58%). Fatigue (21%), hand-foot syndrome (19%) and rash (13%) were the most common TRAEs. Eight patients (15%) experienced grade 3-4 TRAEs, including rash (n=3), hand-foot syndrome (n=2), hypertension (n=1), myocardial enzyme elevation (n=1) and visual field loss (n=1). No treatment-related death occurred. Conclusions: The combination of regorafenib plus PD-1 inhibitors was generally tolerated and exhibited potential benefit in terms of OS and DCR. The presence of baseline liver metastases was predictive for shorter PFS but requires further investigation. Disease control rate of different PD-1 inhibitors.[Table: see text]

Colorectal cancer is a worldwide public health issue, presenting an advanced stage at diagnosis in more than 20% of patients. Liver metastases are the most common metastatic sites and are not indicated for resection in 80% of cases. Unresectable colorectal cancer liver metastases that are refractory to systemic chemotherapy may benefit from transarterial chembolization with irinotecan-loaded beads (DEBIRI). Several studies show the safety and efficacy of DEBIRI for the treatment of colorectal cancer liver metastases. The development of transarterial chembolization and the introduction of new embolics have contributed to better outcomes of DEBIRI. This article reviews the current literature on DEBIRI reporting its use, efficacy in terms of tumor response and survival and side effects.

Rule Out

Hotspot testing for activating KRAS mutations is used in precision oncology to select colorectal cancer (CRC) patients who are eligible for anti-EGFR treatment. However, even for KRASwildtype tumors anti-EGFR response rates are <30%, while mutated-KRAS does not entirely rule out response, indicating the need for improved patient stratification. We performed proteogenomic phenotyping of KRASwildtype and KRASG12V CRC liver metastases (mCRC). Among >9000 proteins we detected considerable expression changes including numerous proteins involved in progression and resistance in CRC. We identified peptides representing a number of predicted somatic mutations, including KRASG12V. For eight of these, we developed a multiplexed parallel reaction monitoring (PRM) mass spectrometry assay to precisely quantify the mutated and canonical protein variants. This allowed phenotyping of eight mCRC tumors and six paired healthy tissues, by determining mutation rates on the protein level. Total KRAS expression varied between tumors (0.47–1.01 fmol/µg total protein) and healthy tissues (0.13–0.64 fmol/µg). In KRASG12V-mCRC, G12V-mutation levels were 42–100%, while one patient had only 10% KRASG12V but 90% KRASwildtype. This might represent a missed therapeutic opportunity: based on hotspot sequencing, the patient was excluded from anti-EGFR treatment and instead received chemotherapy, while PRM-based tumor-phenotyping indicates the patient might have benefitted from anti-EGFR therapy.

Abstract Purpose of Review This review describes recent data supporting locoregional ablative radiation in the treatment of oligometastatic colorectal cancer liver metastases. Recent Findings Stereotactic body radiotherapy (SBRT) demonstrates high rates of local control in colorectal cancer liver metastases when a biologically equivalent dose of > 100 Gy is delivered. Future innovations to improve the efficacy of SBRT include MRI-guided radiotherapy (MRgRT) to enhance target accuracy, systemic immune activation to treat extrahepatic disease, and genomic customization. Selective internal radiotherapy (SIRT) with y-90 is an intra-arterial therapy that delivers high doses to liver metastases internally which has shown to increase liver disease control in phase 3 trials. Advancements in transarterial radioembolization (TARE) dosimetry could improve local control and decrease toxicity. Summary SBRT and SIRT are both promising options in treating unresectable metastatic colorectal cancer liver metastases. Identification of oligometastatic patients who receive long-term disease control from either therapy is essential. Future advancements focusing on improving radiation design and customization could further improve efficacy and toxicity.

There is a lack of useful biomarkers for predicting the efficacy of anti–programmed death-1 (PD-1) therapy for advanced gastric and colorectal cancer. To address this issue, in this study we investigated the correlation between inflammatory marker expression and survival in patients with advanced gastric and colorectal cancer. Data for 111 patients with advanced gastric and colorectal cancer treated with anti–PD-1 regimens were retrospectively analyzed. Neutrophil-to-lymphocyte ratio (NLR), monocyte-to-lymphocyte ratio (MLR), platelet-to-lymphocyte ratio (PLR), and clinical characteristics of each patient were selected as the main variables. Overall response rate, disease control rate, and progression-free survival were primary endpoints, and overall survival and immune-related adverse events (irAEs) were secondary endpoints. The chi-squared test and Fisher’s exact test were used to evaluate relationships between categorical variables. Uni- and multivariate Cox regression analyses were performed, and median progression-free survival and overall survival were estimated with the Kaplan–Meier method. The overall response rate and disease control rate of anti–PD-1therapy in advanced gastric and colorectal tumors were 12.61 and 66.66%, respectively. The patients with MLR &lt; 0.31, NLR &lt; 5, and PLR &lt; 135 had a significantly higher disease control rate than those with MLR &gt; 0.31, NLR &gt; 5, and PLR &gt; 135 (P &lt; 0.05). The multivariate analysis revealed that MLR &lt; 0.31, BMI &gt; 18.5, and anti–PD-1 therapy in first-line were associated with prolonged PFS. MLR &lt; 0.31 and BMI &gt; 18.5 were associated with prolonged overall survival. The irAE rate differed significantly between PLR groups, and PLR &lt; 135 was associated with an increased rate of irAEs (P = 0.028). These results indicate that the inflammatory markers NLR, MLR, and PLR have clinical utility for predicting survival or risk of irAEs in patients with advanced gastric cancer and colorectal cancer.
