Abstract
BACKGROUND Little is known about prognostic factors of brain metastases (BM) from colorectal cancer (CRC). HER2 amplification/overexpression (HER2+) was previously described; its impact on prognosis remains uncertain. METHODS In the translational study HEROES, extensive molecular analysis was performed on primary CRC (prCRC) and their matched resected BM by means of NGS comprehensive genomic profiling and HER2 status as assessed by immunohistochemical/ in situ hybridization. Count of tumour-infiltrating lymphocytes (TILs) was also performed. PRIMARY OBJECTIVE to describe the molecular landscape of paired BM/prCRC. SECONDARY OBJECTIVES to search for new prognostic biomarkers of outcome after BM resection: intracranial-only Progression-Free Survival (BM-iPFS), Progression-Free Survival (BM-PFS), and Overall Survival (BM-OS). RESULTS Out of 22 patients having paired samples of prCRC and BM, HER2+ was found on 4 (18%) BM, 3 (75%) of which also HER2+ in matched prCRC. Lower tumour mutation burden (HR 3.08; 95%CI 1.06-8.93; p = 0.0386) and HER2-negative BM (HER2neg) (HR 7.75;95%CI 1.97-30.40; p = 0.0033) were associated with longer BM-iPFS; HER2neg BM (HR 3.44; 95%CI 1.03-11.53; p = 0.0449) and KRASmut BM (HR 0.31; 95%CI 0.12-0.80; p = 0.0153) conferred longer BM-PFS. Longer BM-OS was found in pts with TILs-enriched (≥1.6/HPF) BM (HR 0.11; 95%CI0.01-0.91; p = 0.0403). CONCLUSIONS This study shows HER2+ enrichment in both BM and their prCRC. TILs-enriched BM conferred better BM-OS.

Abstract
BACKGROUND Reliability of mismatch repair proteins and microsatellite instability assessment is essential in order to define treatment strategy and identify candidates to immune checkpoint inhibitors in locally advanced gastroesophageal carcinoma. We evaluated the concordance of deficient mismatch repair (dMMR) and microsatellite instability-high (MSI-H) status between endoscopic biopsies and surgical specimens. METHODS Consecutive patients with resectable gastric or gastroesophageal junction adenocarcinoma classified as MSI-H/dMMR by polymerase chain reaction (PCR) or immunohistochemistry (IHC) and operated at three referral Institutions were included. The primary endpoint was the rate of concordance between biopsy and surgical samples. If needed, central revision by IHC/PCR was performed by specialized pathologists from coordinating Institutions. RESULTS Thirteen (19.7%) out of 66 patients showed discordant MSI-H/dMMR results in the original pathology reports. In most cases (11, 16.7%) this was due to the diagnosis of proficient mismatch repair status on biopsies. Among the ten cases available for central review, four were due to sample issues, four were reclassified as dMMR, one case showed dMMR status but was classified as microsatellite stable by PCR, one was linked to misdiagnosis of endoscopic biopsy by the local pathologist. Heterogeneity of mismatch repair proteins staining was observed in two cases. CONCLUSIONS Available methods can lead to conflicting results in MSI-H/dMMR evaluation between endoscopic biopsies and surgical samples of gastroesophageal adenocarcinoma. Strategies aiming to improve the reliability of assessment should be primarily focused on the optimization of tissue collection and management during endoscopy and adequate training of dedicated gastrointestinal pathologists within the multidisciplinary team.

Abstract
BACKGROUND Immune checkpoint inhibitors (ICIs) are the standard treatment in patients with mismatch repair deficient (dMMR)/microsatellite instability-high (MSI-H) metastatic colorectal cancer (mCRC). Tumour mutational burden (TMB) is a promising biomarker for the prediction of treatment outcomes. PATIENTS AND METHODS We screened 203 patients with dMMR/MSI-H mCRC treated with an anti-PD-(L)1 (anti-Programmed-Death-(Ligand)1) plus or minus an anti-Cytotoxic T-Lymphocyte Antigen 4 (anti-CTLA-4) agent at three Italian Academic Centers. TMB was tested by Foundation One Next Generation Sequencing assay and correlated with clinical outcomes, in the overall population and according to ICI regimen. RESULTS We included 110 patients with dMMR/MSI-H mCRC. Eighty patients received anti-PD-(L)1 monotherapy and 30 received anti-CTLA-4 combinations. Median TMB was 49 mut/Mb (range: 8-251 mut/Mb). The optimal prognostic cut-off for progression-free survival (PFS) stratification was 23 mut/Mb. Patients with TMB ≤23 mut/Mb had significantly worse PFS (adjusted Hazard Ratio [aHR] = 4.26, 95% confidence interval [CI]:1.85-9.82, p = 0.001) and overall survival (OS) (aHR = 5.14, 95% CI: 1.76-14.98, p = 0.003). Using a cut-off optimised for predicting treatment outcome, anti-CTLA-4 combination was associated with a significant PFS/OS benefit versus anti-PD-(L)1 monotherapy in patients with TMB>40 mut/Mb (2-year PFS: 100.0% versus 70.7%, p = 0.002; 2-year OS: 100.0% versus 76.0%, p = 0.025), but not in those with TMB ≤40 mut/Mb (2-year PFS: 59.7% versus 68.6%, p = 0.888; 2-year OS: 80.0% versus 81.0%, p = 0.949). CONCLUSION Patients with dMMR/MSI-H mCRC and relatively lower TMB value displayed early disease progression when receiving ICIs, whereas patients with the highest TMB values may obtain the maximal benefit from intensified anti-CTLA-4/PD-1 combination.

Abstract
218 Background: Immune checkpoint inhibitors (ICI) showed high efficacy in both first and subsequent lines in metastatic colorectal cancer with mismatch repair deficiency (dMMR-mCRC); however, they still fail in a minority of patients (pts). In non-preplanned analyses from previous studies, RAS mutations ( RASm) have been related to limited activity of ICI monotherapy (ICIm) as compared to ICI doublets (ICId) in dMMR-mCRC. Emerging data suggest different immunological features in presence of RASm, resulting in lower immunogenicity. Methods: NERDY is a retrospective, monocentric study designed to investigate the effect of ICIm and ICId on dMMR-mCRC basing on RASm. Pts with dMMR-mCRC treated with ICIm/ICId at our Institute were included. Clinical-pathological features for each patient were collected. On primary tumor specimens, proinflammatory pathways and CMS subgroup will be assessed by Nanostring and RNA-Seq respectively. The study is exploratory and no formal hypothesis has been postulated. Both PFS and OS were calculated with Kaplan-Meier. Cox proportional hazard model was adopted in the interaction tests. Primary objective was to assess OS and PFS according to RAS in dMMR-mCRC pts treated with ICIm or ICId. Secondary objectives were to describe the inflammatory infiltrate and TMB in dMMR-mCRC according to RAS status. Results: From June 2015 to January 2022, a total of 126 consecutive dMMR-mCRC pts treated with ICI were included, 33 RASm/93 RASwt. RASm pts were more frequently males (p=0.015) and younger (median age 47 vs 65). An imbalance was observed in sidedness (more right-CRC in RASwt than in RASm as BRAF effect, p=0.001) and timing of ICI (administered in later lines in RASm, p=0.013). No differences in ECOG-PS, histotype, disease burden, stage at diagnosis, treatment with ICIm vs ICId and best response. At a median follow up of 53.5 months (95%CI 34.7-56.9), a trend toward longer PFS in pts treated with ICId over ICIm was found in the overall population (HR 0.62; 95%CI 0.36-1.05; p=0.055), being significantly longer in RASm-only pts (HR 0.41; 95%CI 0.13-1.28; p=0.047) but not in RASwt-only pts (HR 0.64; 95%CI 0.34-1.20; p=0.139). No difference was observed in OS between ICId and ICIm in the overall population (HR 0.64; 95%CI 0.36-1.16; p=0.121), in RASwt (HR 0.59; 95%CI 0.29-1.20; p=0.132) nor in RASm pts (HR 0.59; 95%CI 0.19-1.78; p=0.275). Interaction test for RAS and ICI treatment type was not significant for PFS (HR 0.63; 95%CI 0.21-1.94; p=0.423) nor for OS (HR=1.00; 95%CI 0.29-3.41; p=0.999). Conclusions: Preliminary clinical results of the NERDY study suggest enhanced activity of ICId compared to ICIm in pts with RASm dMMR-mCRC. Further data are expected from pending translational analyses and a pre-planned adjunctive cohort from two other Italian centers will be used for external validation.

Abstract
Human epidermal growth factor receptor 2 (HER2) is a well-known oncogenic driver in different tumors and an approved therapeutic target in breast and gastroesophageal cancer. In metastatic colorectal cancer, only 3% to 5% of patients present with HER2 alterations: somatic mutations and amplifications. HER2 was first assessed as a biomarker of resistance to anti-EGFR therapy; however, in more recent years, its role as a potential actionable target has emerged. In this article, we discuss the predictive and prognostic value of HER2 in metastatic colorectal cancer, its emerging role as an actionable therapeutic target, and its possible future developments.
