Abstract
Importance The combination of a triple-drug chemotherapy regimen with an anti-epidermal growth factor receptor (EGFR) agent as a first-line treatment of metastatic colorectal cancer (mCRC) showed promising activity along with safety concerns in single-arm phase 2 trials. The role of maintenance following chemotherapy and anti-EGFR and the optimal regimen to be adopted are not established. Objectives To evaluate the activity and safety of cetuximab plus modified FOLFOXIRI (mFOLFOXIRI) and explore the role of maintenance with cetuximab or bevacizumab in RAS and BRAF wild-type mCRC. Design, Setting, and Participants In a prospective, noncomparative, open-label, multicenter, randomized phase 2 trial, patients aged 18 to 75 years with unresectable, previously untreated RAS and BRAF wild-type (before amendment, KRAS wild-type) mCRC were recruited from 21 oncology units in Italy from October 19, 2011, to March 1, 2015 (followed up through May 31, 2017). In total, 323 patients were screened and 143 were randomized to 2 treatment arms to receive as a first-line induction a regimen of mFOLFOXIRI plus cetuximab followed by cetuximab (arm A) or bevacizumab (arm B) until disease progression. Primary analyses were conducted in a modified intention-to-treat population. Interventions mFOLFOXIRI plus cetuximab repeated every 2 weeks for up to 8 cycles, followed by maintenance with cetuximab or bevacizumab until disease progression. Main Outcomes and Measures The primary end point was the 10-month progression-free rate (PFR); secondary end points included progression-free and overall survival, response rate, rate of metastases resection, and adverse events. Results Of 143 patients randomized, 116 (81.1%) (median [interquartile range (IQR)] age, 59.5 [53-67] years; 34 [29.3%] women) had RAS and BRAF wild-type mCRC. At a median (IQR) follow-up of 44.0 (30.5-52.1) months, 10-month PFRs were 50.8% (90% CI, 39.5%-62.2%) in arm A and 40.4% (90% CI, 29.4%-52.1%) in arm B. The overall response rate was 71.6% (95% CI, 62.4%-79.5%). Main grade 3/4 adverse events were neutropenia (occurring in 36 patients [31%]), diarrhea (in 21 patients [18%]), skin toxic effects (in 18 patients [16%]), asthenia (in 11 patients [9%]), stomatitis (in 7 patients [6%]), and febrile neutropenia (in 3 patients [3%]). Conclusions and Relevance Although neither of the 2 arms met the primary end point, the findings indicate that a 4-month induction regimen of mFOLFOXIRI plus cetuximab is feasible and provides relevant activity results, leading to a high surgical resection rate.

Abstract
BACKGROUND V600EBRAF mutated metastatic colorectal cancer (mCRC) is a subtype (10%) with overall poor prognosis, but the clinical experience suggests a great heterogeneity in survival. It is still unexplored the real distribution of traditional and innovative biomarkers among V600EBRAF mutated mCRC and which is their role in the improvement of clinical prediction of survival outcomes. METHODS Data and tissue specimens from 155 V600EBRAF mutated mCRC patients treated at eight Italian Units of Oncology were collected. Specimens were analysed by means of immunohistochemistry profiling performed on tissue microarrays. Primary endpoint was overall survival (OS). RESULTS CDX2 loss conferred worse OS (HR = 1.72, 95%CI 1.03-2.86, p = 0.036), as well as high CK7 expression (HR = 2.17, 95%CI 1.10-4.29, p = 0.026). According to Consensus Molecular Subtypes (CMS), CMS1 patients had better OS compared to CMS2-3/CMS4 (HR = 0.37, 95%CI 0.19-0.71, p = 0.003). Samples showing less TILs had worse OS (HR = 1.72, 95%CI 1.16-2.56, p = 0.007). Progression-free survival analyses led to similar results. At multivariate analysis, CK7 and CMS subgrouping retained their significant correlation with OS. CONCLUSION The present study provides new evidence on how several well-established biomarkers perform in a homogenousV600EBRAF mutated mCRC population, with important and independent information added to standard clinical prognosticators. These data could be useful to inform further translational research, for patients' stratification in clinical trials and in routine clinical practice to better estimate patients' prognosis.

Abstract
BACKGROUND Microsatellite instable/deficient mismatch repair (MSI/dMMR) metastatic colorectal cancers have been reported to have a poor prognosis. Frequent co-occurrence of MSI/dMMR and BRAFV600E complicates the association. PATIENTS AND METHODS Patients with resected stage III colon cancer (CC) from seven adjuvant studies with available data for disease recurrence and MMR and BRAFV600E status were analyzed. The primary end point was survival after recurrence (SAR). Associations of markers with SAR were analyzed using Cox proportional hazards models adjusted for age, gender, performance status, T stage, N stage, primary tumor location, grade, KRAS status, and timing of recurrence. RESULTS Among 2630 patients with cancer recurrence (1491 men [56.7%], mean age, 58.5 [19-85] years), multivariable analysis revealed that patients with MSI/dMMR tumors had significantly longer SAR than did patients with microsatellite stable/proficient MMR tumors (MSS/pMMR) (adjusted hazard ratio [aHR], 0.82; 95% CI [confidence interval], 0.69-0.98; P = 0.029). This finding remained when looking at patients treated with standard oxaliplatin-based adjuvant chemotherapy regimens only (aHR, 0.76; 95% CI, 0.58-1.00; P = 0.048). Same trends for SAR were observed when analyzing MSI/dMMR versus MSS/pMMR tumor subgroups lacking BRAFV600E (aHR, 0.84; P = 0.10) or those harboring BRAFV600E (aHR, 0.88; P = 0.43), without reaching statistical significance. Furthermore, SAR was significantly shorter in tumors with BRAFV600E versus those lacking this mutation (aHR, 2.06; 95% CI, 1.73-2.46; P < 0.0001), even in the subgroup of MSI/dMMR tumors (aHR, 2.65; 95% CI, 1.67-4.21; P < 0.0001). Other factors associated with a shorter SAR were as follows: older age, male gender, T4/N2, proximal primary tumor location, poorly differentiated adenocarcinoma, and early recurrence. CONCLUSIONS In stage III CC patients recurring after adjuvant chemotherapy, and before the era of immunotherapy, the MSI/dMMR phenotype was associated with a better SAR compared with MSS/pMMR. BRAFV600E mutation was a poor prognostic factor for both MSI/dMMR and MSS/pMMR patients.

Abstract
Importance Few studies are available on the role of maintenance strategies after induction treatment regimens based on anti-epidermal growth factor receptors, and the optimal regimen for an anti-epidermal growth factor receptors-based maintenance treatment in patients with RAS wild-type metastatic colorectal cancer is still to be defined. Objective To determine whether maintenance therapy with single-agent panitumumab was noninferior to panitumumab plus fluorouracil and leucovorin after a 4-month induction treatment regimen. Design, Setting, and Participants This open-label, randomized phase 2 noninferiority trial was conducted from July 7, 2015, through October 27, 2017, at multiple Italian centers. Patients with RAS wild-type, unresectable metastatic colorectal adenocarcinoma who had not received previous treatment for metastatic disease were eligible. Induction therapy consisted of panitumumab plus FOLFOX-4 (panitumumab, 6 mg/kg, oxaliplatin, 85 mg/m2 at day 1, leucovorin calcium, 200 mg/m2, and fluorouracil, 400-mg/m2 bolus, followed by 600-mg/m2 continuous 24-hour infusion at days 1 and 2, every 2 weeks). Cutoff date for analyses was July 30, 2018. Interventions Patients were randomized (1:1) to first-line panitumumab plus FOLFOX-4 for 8 cycles followed by maintenance therapy with panitumumab plus fluorouracil-leucovorin (arm A) or panitumumab (arm B) until progressive disease, unacceptable toxic effects, or consent withdrawal. The minimization method was used to stratify randomization by previous adjuvant treatment and number of metastatic sites. Main Outcomes and Measures The prespecified primary end point was 10-month progression-free survival (PFS) analyzed on an intention-to-treat basis with a noninferiority margin of 1.515 for the upper limit of the 1-sided 90% CI of the hazard ratio (HR) of arm B vs A. Results Overall, 229 patients (153 male [66.8%]; median age, 64 years [interquartile range (IQR), 56-70 years]) were randomly assigned to arm A (n = 117) or arm B (n = 112). At a median follow-up of 18.0 months (IQR, 13.1-23.3 months]), a total of 169 disease progression or death events occurred. Arm B was inferior (upper limit of 1-sided 90% CI of the HR, 1.857). Ten-month PFS was 59.9% (95% CI, 51.5%-69.8%) in arm A vs 49.0% (95% CI, 40.5%-59.4%) in arm B (HR, 1.51; 95% CI, 1.11-2.07; P = .01). During maintenance, arm A had a higher incidence of grade 3 or greater treatment-related adverse events (36 [42.4%] vs 16 [20.3%]) and panitumumab-related adverse events (27 [31.8%] vs 13 [16.4%]), compared with arm B. Conclusions and Relevance In patients with RAS wild-type metastatic colorectal cancer, maintenance therapy with single-agent panitumumab was inferior in terms of PFS compared with panitumumab plus fluorouracil-leucovorin, which slightly increased the treatment toxic effects.

Abstract
Background and Aims The aim of the present study is to evaluate a new index influenced by the balance between the immune system, α-fetoprotein (AFP), and lactate dehydrogenase (LDH) (RAPID index) as a prognostic factor in patients treated with sorafenib. Methods This study was conducted on a training cohort of 159 hepatocellular carcinoma (HCC) patients and a validation cohort of 68 HCC patients treated with sorafenib. The RAPID index was calculated as neutrophil/lymphocyte count × LDH × AFP. Results In the training cohort, the median overall survival (OS) was 23.2 months (95% CI 11-25) and 12.1 months (95% CI 9-15) for patients with a low (≤3,226) and high (>3,226) RAPID index, respectively (ref. <3,226, HR = 0.56, 95% CI 0.35-0.88, p = 0.017). Following adjustment for clinical covariates, multivariate analysis confirmed the RAPID index ≤3,226 versus >3,226 (HR = 0.37, 95% CI 0.18-0.74, p = 0.0054) as an independent prognostic factor for OS. In the validation cohort, the median OS was 26.9 months (95% CI 17.6-26.9) and 7.0 months (95% CI 6.2-9.2) for patients with a low (≤ 3,226) and high (>3,226) RAPID index, respectively (ref. <3,226, HR = 0.19, 95% CI 0.10-0.36, p < 0.0001). Performing the same multivariate analysis of the training cohort (AFP, Eastern Cooperative Oncology Group, aspartate aminotransferase, neutrophil, platelet, systemic inflammatory index and RAPID index), the RAPID index <3,226 versus >3,226 (HR = 3.86, 95% CI 1.45-10.29, p = 0.007) was found to be an independent prognostic factor for predicting OS. Conclusion The low cost, easy assessment, and reproducibility of a full blood count make the RAPID index a promising tool for assessing HCC prognosis in future clinical practice.

Abstract
The overall 5-year survival of gastric cancer (GC) has change only little in the last decades and it remains the fifth leading cause of cancer-related death worldwide. However, in the past few years a more effective combination chemotherapy has raised the bar of curability of about 10% in resectable disease. Morever, a deeper knowledge of GC biology have unveiled biomarkers to help personalize adjunctive treatments in patients candidate to surgery. Despite a plateau in efficacy of fist-line treatment, incremental survival advantages have been recorded in unresectable advanced disease. The growing number of effective drugs in second and later lines along with a more judicious delivery of cytotoxics and early supportive interventions have enabled more patients to proceed beyond first-line. The continuum of care has become a reality in a considerable proportion of patients that offer opportunities to improve outcomes. Finally, the advent of the immune checkpoint inhibitors has brought great expectations in molecularly-defined subset of patients. This Review summarizes the state-of-the art in the management of GC together with novel concepts that have entered clinical development with the potential of change practice in the foreseeable future.

Abstract
Polymorphisms contribute to inter-individual differences and show a promising predictive role for chemotherapy-related toxicity in colon cancer (CC). TOSCA is a multicentre, randomized, non-inferiority, phase III study conducted in high-risk stage II/stage III CC patients treated with 6 vs 3 months of FOLFOX-4 or XELOX adjuvant chemotherapy. During this post-hoc analysis, 218 women and 294 men were genotyped for 17 polymorphisms: TYMS (rs34743033, rs2853542, rs11280056), MTHFR (rs1801133, rs1801131), ERCC1 (rs11615), XRCC1 (rs25487), XRCC3 (rs861539), XPD (rs1799793, rs13181), GSTP1 (rs1695), GSTT1/GSTM1 (deletion +/−), ABCC1 (rs2074087), and ABCC2 (rs3740066, rs1885301, rs4148386). The aim was to assess the interaction between these polymorphisms and sex, on safety in terms of time to grade ≥3 haematological (TTH), grade ≥3 gastrointestinal (TTG) and grade ≥2 neurological (TTN) toxicity. Interactions were detected on TTH for rs1801133 and rs1799793, on TTG for rs13181 and on TTN for rs11615. Rs1799793 GA genotype (p = 0.006) and A allele (p = 0.009) shortened TTH in men. In women, the rs11615 CC genotype worsened TTN (co-dominant model p = 0.008, recessive model p = 0.003) and rs13181 G allele improved the TTG (p = 0.039). Differences between the two sexes in genotype distribution of rs1885301 (p = 0.020) and rs4148386 (p = 0.005) were found. We highlight that polymorphisms could be sex-specific biomarkers. These results, however, need to be confirmed in additional series.

Abstract
INTRODUCTION Exocrine pancreatic cancers include common type pancreatic ductal adenocarcinoma and cystic neoplasms, which account for 85% and 10% of cases, respectively. The remaining 5% are rare histotypes, comprising adenosquamous carcinoma, acinar cell carcinoma, signet ring cell carcinoma, medullary carcinoma, pancreatoblastoma, hepatoid carcinoma, undifferentiated carcinoma and its variant with osteoclast-like giant cells, solid pseudopapillary carcinoma, and carcinosarcoma. Due to their low incidence, little knowledge is available on their clinical and molecular features as well as on treatment choices. The national initiative presented here aims at the molecular characterization of series of rare histotypes for which therapeutic and follow-up data are available. METHODS A nationwide Italian Rare Pancreatic Cancer (IRaPaCa) task force whose first initiative is a multicentric retrospective study involving 21 Italian cancer centers to retrieve histologic material and clinical and treatment data of at least 100 patients with rare exocrine pancreatic cancers has been created. After histologic revision by a panel of expert pathologists, DNA and RNA from paraffin tissues will be investigated by next-generation sequencing using molecular pathway-oriented and immune-oriented mutational and expression profiling panels constructed availing of the information from the International Cancer Genome Consortium. Bioinformatic analysis of data will drive validation studies by immunohistochemistry and in situ hybridization, as well as nanostring assays. CONCLUSIONS We expect to gather novel data on rare pancreatic cancer types that will be useful to inform the design of therapeutic choices.

Abstract
Background: Regorafenib improves progression free survival (PFS) in a subset of metastatic colorectal cancer (mCRC) patients, although no biomarkers of efficacy are available. Circulating methylated DNA (cmDNA) assessed by a five-gene panel was previously associated with outcome in chemotherapy treated mCRC patients. We hypothesized that cmDNA could be used to identify cases most likely to benefit from regorafenib (i.e., patients with PFS longer than 4 months). Methods: Plasma samples from mCRC patients were collected prior to (baseline samples N = 60) and/or during regorafenib treatment (N = 62) for the assessment of cmDNA and total amount of cell free DNA (cfDNA). Results: In almost all patients, treatment with regorafenib increased the total cfDNA, but decreased cmDNA warranting the normalization of cmDNA to the total amount of circulating DNA (i.e., cmDNA/ml). We report that cmDNA/ml dynamics reflects clinical response with an increase in cmDNA/ml associated with higher risk of progression (HR for progression = 1.78 [95%CI: 1.01-3.13], p = 0.028). Taken individually, high baseline cmDNA/ml (above median) was associated with worst prognosis (HR for death = 3.471 [95%CI: 1.83-6.57], p < 0.0001) and also predicted shorter PFS (<16 weeks with PPV 86%). In addition, high cmDNA/ml values during regorafenib treatment predicted with higher accuracy shorter PFS (<16 weeks with a PPV of 96%), therefore associated with increased risk of progression (HR for progression = 2.985; [95%CI: 1.63-5.46; p < 0.0001). Conclusions: Our data highlight the predictive and prognostic value of cmDNA/ml in mCRC patients treated with regorafenib.

Abstract
BACKGROUND Claudin-18 (CLDN18) is a highly specific tight junction protein of the gastric mucosa. An isoform of CLDN18, the Claudin 18.2, has recently emerged as an innovative drug target for metastatic gastric cancer. METHODS We investigated the immunohistochemical profile of CLDN18, p53, p16, E-cadherin, MSH2, MSH6, MLH1, PSM2, HER2, and PDL-1 in a large series of 523 primary gastric carcinomas (GCs; n = 408) and gastro-oesophageal carcinomas (GECs; n = 115) and 135 matched and synchronous nodal metastases. The status of HER2 and EBER by means of chromogenic in situ hybridisation (CISH) was also evaluated. RESULTS High membranous CLDN18 expression was present in 150/510 (29.4%) primary cases and in 45/132 (34.1%) metastases. An abnormal expression (i.e. nuclear and/or cytoplasmic) was observed in 115 (22.5%) primary cases and in 33 (25.0%) metastases. A 38.8% of the cases showed significant CLDN18 intratumoural variability among the different tissue microarray cores obtained from the same tumour. Positive membrane CLDN18 expression was statistically associated with non-antral GCs (p = 0.016), Lauren diffuse type (p = 0.009), and with EBV-associated cancers (p < 0.001). CONCLUSIONS CLDN18 is frequently expressed in gastric and gastro-oesophageal cancers; further studies should investigate the prognostic significance of CLDN18 heterogeneity in order to implement its test into clinical practice.

Abstract
Introduction: Lung metastases occur in 10-20% of patients with colorectal cancer (CRC). Most of them are treated with palliative intent and have a poor prognosis. Pulmonary metastasectomy may be a curative option for carefully selected patients with 5-year survival rates ranging from 25% to 60%. However, up to 70% of patients develop recurrence after pulmonary metastasectomy. Therefore, the identification of prognostic factors is essential in CRC patients with resectable lung metastases. Areas covered: This review aims at summarizing the actual body of knowledge available on lung metastases from CRC focusing on their clinical, pathological and molecular profile. Moreover, we provide an update on experts' attitudes towards lung metastasectomy, adjuvant or perioperative chemotherapy. Expert opinion: Traditional clinical prognosticators such as the total number of pulmonary metastases, carcinoembryonic antigen (CEA) serum levels before surgery, and presence of lymph node metastases cannot provide reliable criteria to predict survival after lung metastasectomy. Indeed, research efforts have been directed in recent years toward studying the biological characteristics of lung lesions to better define prognosis and response to treatment, and ultimately shed new light on their proper local and systemic management.

Abstract
3501 Background: 6m of oxaliplatin-based treatment is an option as adj chemotherapy for patients with high risk stage II CC (T4, inadequate nodal harvest, poorly differentiated, obstruction, perforation or vascular/perineural invasion). The IDEA collaboration showed shorter treatment duration to be appropriate for most pts with stage III colon cancer. The results of the 4 IDEA studies with stage II pts are presented here. Methods: A prospective, pre-planned pooled analysis of high-risk stage II patients from 4 concurrently conducted randomized phase III trials (SCOT, TOSCA, ACHIEVE-2, HORG) was performed to evaluate non-inferiority (NI) of 3m compared with 6m (ref) of adj FOLFOX/CAPOX (regimen preselected, not randomized). The primary endpoint was disease-free survival (DFS), NI was to be declared if the 2-sided 80% confidence interval (CI) for DFS hazard ratio (HR 3m v 6m) estimated by a stratified Cox model was below 1.2. 542 DFS events were required to provide 80% power to declare NI. NI was also examined within regimen, T4 (Yes v No) and inadequate nodal harvest (Yes v No) as pre-planned subgroups. Results: The primary analysis included 3273 randomised pts of which 1254 had FOLFOX and 2019 had CAPOX. There were 552 events and the median follow-up was 60.2 m. There was significantly less grade 3-5 toxicity with 3m treatment (p < .0001). The 5-year DFS rate was 80.7% and 84.0% for 3m and 6m treatment with an estimated DFS HR of 1.18 (80% CI:1.05-1.31, p for NI = 0.404). For CAPOX the estimated HR was 1.02 (80% CI: 0.88-1.17, p for NI = 0.087) and for FOLFOX the estimated HR was 1.42 (80% CI: 1.19-1.70, p for NI = 0.894). The test for interaction between duration and regimen was not statistically significant (p = .174 adjusted for multiple testing) but was stronger than that for the other subgroups examined. Conclusions: In the overall population non-inferiority for 3m adj treatment in pts with high-risk stage II CC was not shown. As with the stage III population the choice of adj regimen appears important (although this did not reach statistical significance) with a small difference in DFS between 3 and 6 m treatment if CAPOX is used. Clinical trial information: ISRCTN59757862.

Abstract
3508 Background: In the phase III TRIBE study FOLFOXIRI/bev significantly improved Response Rate (RR), PFS and OS when compared with FOLFIRI/bev as initial treatment of mCRC. However, the actual advantage by the triplet could be lower when compared with a pre-planned sequential strategy of doublets (FOLFOX, FOLFIRI). TRIBE2 (NCT02339116) is a phase III trial in which unresectable mCRC pts were randomized 1:1 to FOLFOX/bev followed by FOLFIRI/bev after PD (arm A) or FOLFOXIRI/bev followed by the reintroduction of the same regimen after PD (arm B). A pre-planned interim analysis showed a significant advantage for arm B in terms of PFS2, primary endpoint of the study, defined as the time from randomization to PD on any treatment given after first PD or death (PD2). Methods: The study had 80% power to detect a HR for PFS2 of 0.77 in favor of arm B with an overall 2-sided-α error of 0.05 (0.0131 and 0.0455 for the interim and final analyses, planned at 303 and 466 PFS2 events, respectively). Secondary endpoints included RR, 1st-PFS, i.e. the time from randomization to the first evidence of PD or death (PD1), 2nd-PFS, i.e. the time from PD1 to PD2, and OS. Results: From February 2015 to May 2017, 679 pts (arm A/B: 340/339) were enrolled in 58 Italian sites. Main pts’ characteristics were (arm A/B): right side 38%/38%, synchronous mets 89%/89%, RAS mutant 65%/63%, BRAF mutant 10%/10%. At a median follow up of 30.6 mos, 514 (arm A/B: 272/242) PD2, 594 (arm A/B: 303/291) PD1 and 408 (arm A/B: 217/191) OS events were collected. A significant advantage by upfront FOLFOXIRI/bev was confirmed in terms of PFS2 (19.1 vs 16.4 mos, HR 0.74, 95%CI 0.62-0.88, p<0.001), RR (62% vs 50%, OR 1.61, 95%CI 1.19-2.18, p=0.002) and 1st-PFS (12.0 vs 9.8 mos, HR 0.75, 95%CI 0.63-0.88, p<0.001). A significant OS benefit for pts in arm B was also observed (27.6 vs 22.6 mos, HR: 0.81, 95%CI: 0.67-0.98, p=0.033). Out of 594 pts with a PD1 event, 470 (79%, arm A/B: 251/219) received a treatment after PD. In the per-protocol analysis (N=323), pts in arm B showed significantly longer 2nd-PFS (6.5 vs 5.8 mos, HR 0.76, 95%CI 0.59-0.97, p=0.024). Conclusion: Upfront FOLFOXIRI/bev followed by the pre-planned reintroduction of the same agents after PD provided a statistically significant and clinically relevant PFS2 and OS benefit when compared with the pre-planned sequential administration of FOLFOX/bev and FOLFIRI/bev in unresectable mCRC patients. A median OS of 27.6 mos was reached despite the high percentage of pts with poor prognostic features ( RAS and BRAF mutations, right side, synchronous mets). Clinical trial information: NCT02339116.

Abstract
11552 Background: About 50% of diagnoses of colorectal cancer (CRC) occur in patients (pts) older than 70 years. Though a comprehensive geriatric assessment (CGA) is recommended for proper management of older cancer pts, there is still no consensus on the best form of geriatric assessment. We investigated possible prognostic factors in elderly metastatic (m)CRC pts in a real-world setting, focusing on the role of the oncological-multidimensional prognostic index (onco-MPI). Methods: Pts aged ≥ 70 years with mCRC referred to the Medical Oncology 1 Unit from May 2010 to May 2017 were assessed by a multidisciplinary team and received a basal CGA. Onco-MPI was calculated by a validated algorithm as a weighted linear combination of the CGA domains, as previously described. The following 3 different prognostic groups were identified: low (scores 0.0-0.46), medium (scores 0.47-0.63) and high risk (scores 0.64-1.0). Results: A total of 206 mCRC pts were included, 123 males. Mean age was 76.1 years (69.2-90.8). ECOG PS was < 2 in 90% and mini-mental state examination was ≥ 24 in 85% of pts. Primary tumor was located in rectum, left and right side in 18%, 42% and 40% of pts, respectively. RAS and BRAF mutations were detected in 44% and 9% of pts, respectively. According to onco-MPI score, 32%, 39% and 28% of cases were low, medium and high risk, respectively. According to CGA as per Balducci’s criteria, 56% of pts were classified as fit, 31% vulnerable and 13% frail. Median overall survival (OS) was 26 months (95% CI 19.7-32.4). The following factors were significantly associated with OS: ECOG PS (0-1 vs > 1, 31% vs 15%, p = 0.004); onco-MPI score (low vs medium vs high risk, 29% vs 38% vs 19%, p = 0.005), treatment (monotherapy vs doublet vs triplet, 20% vs 31% vs 30%, p = 0.01). No significant difference in OS was observed in CGA-based groups (p = 0.15). In high onco-MPI score, doublet-regimen correlated with higher OS compared to monotherapy (79% vs 51%, p = 0,03). Conclusions: Onco-MPI emerged as a significant prognosticator in mCRC elderly pts. It may be useful in daily clinical practice for driving decision-making in this age group. Thanks to its marked standardization it may be also applied in clinical trials.

Abstract
e15607 Background: FGFR2 fusions are prevalent in 13-22% of iCCA and known oncogenic drivers. DZB is a kinase inhibitor with potent pan-FGFR activity. In a non-comparative Phase 2a study, DZB was administered to 29 pts with FGFR2-fusion positive advanced, inoperable iCCA, either as first-line (1L) (n = 2), 2L (n = 13), 3L (n = 10), 4L (n = 2) or 5L therapy (n = 2). The objective response rate (ORR) with DZB was 21%, disease-control rate (DCR) 83% and median PFS 5.7 months (Mazzaferro et al. 2018 BJC). Data from biliary tract cancer studies suggest decreasing treatment effects of chemotherapy with increasing lines of treatment. Here, we present a post-hoc analysis of outcomes of pts treated with DZB in 1L/2L (n = 15) compared to pts treated post-2L (n = 14). Methods: Pts received 300 mg DZB QD PO. Eligibility criteria included locally confirmed, positive testing of FGFR2 fusion expression (FISH or NGS), ECOG PS 0-1. Objective responses were determined using RECIST 1.1. Disease control rate was defined as CR, PR or SD. Results: The mean age of pts treated in 1L/2L was 66y and 55y in post-2L; 73% were females in 1L/2L and 50% in post-2L treatment; other demographic variables were balanced between groups (87% vs 86% of liver target lesions, median baseline lesion size of 97.5 mm vs 109.5 mm, ECOG PS0 was 60% vs 71%). Of 15 1L/2L group pts, 12 (80%) had prior platinum-based chemotherapy as compared to all 14 pts in the post-2L group. In the 1L/2L and post-2L groups, ORR was 20% and 21%, DCR was 80% and 86%, and a reduction in sum of the largest diameter of target lesions was observed in 60% and 64% of pts, respectively. Median PFS was 5.5 mo (95% CI, 1.9-11.9) and 6.2 mo (3.6-9.2) for the 1L/2L and post-2L groups, respectively. Types of drug-related adverse events were similar in 1L/2L and post-2L. Conclusions: Anti-tumor efficacy of DZB in iCCA patients measured either by ORR, DCR, tumor shrinkage or PFS was numerically similar irrespective of treatment line. These data suggest that DZB is an effective treatment option that can be applied early in the treatment continuum of iCCA patients or at later stages to offer anti-tumor efficacy and disease control.

Abstract
4066 Background: This study evaluates the feasibility, safety and efficacy of a trimodality treatment, with surgery postponed after neoadjuvant chemotherapy (CT) and chemoradiotherapy (CRT), in LAGC. Methods: Patients (pts) with cT3-4 and/or N+ LAGC were eligible. Staging included endoscopic ultrasound, PET-CT and laparoscopy. Three cycles of EOX (Epirubicyn 50mg/m2,q21 days, Oxaliplatin 130mg/m2,q21 days, and Capecitabine 625mg/m2 bid, by continuous oral administration (c.a.), followed by IMRT with 45Gy/25 frs, concurrent Capecitabine 625mg/m2 bid c.a. and weekly Oxaliplatin 30mg/m2 for 5 wks, was planned. Early PET-CT was performed after the 2nd EOX cycle to assess response or disease progression. Restaging was repeated after CT and CRT. Surgery was planned 4-6 wks after CRT, 22 wks from the start of NEOX-RT. Pathologic complete response (pCR) was the primary endpoint. Results: From November 2008 to March 2016, 51 pts (5 G-E Junction, 17 Cardia, 15 Corpus, 14 Antrum) entered the study. The NEOX-RT program was completed in 46 pts (90%) who proceeded to surgery and are assessable. Grade 3-4 toxicity (NCI-CTC criteria v.3) occurred in 13/51 pts (25%) during EOX, including 1 toxic death, and 9.5% CT cycles required dose modification, resulting in a CT compliance of 90%. No pts had progression during CT. Persistent G2-G3 toxicity occurred in 32/46 pts (69%) during CRT. However, 41/46 pts (89%) received the planned 45Gy with Capecitabine at dose ≥75% and 4-5 cycles of weekly Oxaliplatin in 52% pts. Curative resection (R0) rate was 89%; 4 pts (8.7%) had peritoneal carcinomatosis at surgery done after a median of 23 wks. pCR was reported in 9/46 pts (19.6%). Major postop complications occurred in 5 pts (11%). At median f-up of 62 mos (23-109), 5-yr OS and DFS in all and pCR pts were 58%, 100% and 51%, 75%, respectively. Conclusions: This trimodality program was feasible and safe. Most pts completed the planned treatment. The pCR rate of 19.6% was remarkable and met the hypothesis of pCR = 20%. A high R0 rate was also reported and delayed surgery didn’t increase complications. The notable survival rates are available to be compared with ongoing phase III trials. Clinical trial information: 2008-002715-40.

Abstract
3540 Background: Retrospective analyses and phase 2 studies suggest that administering an anti-EGFR in advanced lines may be effective in mCRC pts who achieved benefit from a 1st-line anti-EGFR containing regimen. The identification of clinical features associated with benefit from anti-EGFR re-treatment (re-tx) in pts experiencing PD during 1st-line anti-EGFR (rechallenge) or after its interruption (reintroduction), is a major clinical need. Methods: A real-life data-base including a total of 5530 pts treated at 6 insitutions from December 2010 to October 2018 was queried. Pts retreated with anti-EGFRs, with RAS/ BRAF wild-type status on tissue samples, who had received a 1st-line anti-EGFR-based tx with at least SD as best response, and at least one further line of therapy before anti-EGFR re-tx, were included. The association with RECIST response (RR), PFS and OS was investigated for the following variables: RR (PR or CR vs SD) and PFS during 1st-line; time from the last anti-EGFR administration to 1st-line PD (i.e. re-introduction vs rechallenge); reason for anti-EGFR discontinuation in 1st-line (PD vs. other); number of anti-EGFR-free lines of therapy before re-tx; anti-EGFR free interval (time between the last anti-EGFR administration in 1st-line and the time of re-tx); primary tumor side; time from the diagnosis of metastatic disease to re-tx (≥ vs. < 18 mos). Results: Data from 86 patients were retrieved, 56 (65%) and 30 (35%) received anti-EGFR rechallenge or reintroduction, respectively. Median anti-EGFR free interval was 15.1 mos. The RR during re-tx was 19.8%, with a DCR of 46.5%. Median PFS and OS were 3.6 and 10.2 mos, respectively. No significant association of investigated features with RR and PFS was observed. No differences in RR or PFS were observed among patients receiving anti-EGFR re-tx as rechallenge or reintroduction (20.4% vs 23.1%, p = 0.99; median PFS: 3.49 vs 4.97 mos, p = 0.61). Patients with left-sided tumors had longer OS (HR: 0.50, 95%CI: 0.26-0.93, p = 0.005). Conclusions: Clinical factors that are generally believed to affect the efficacy of anti-EGFR re-tx are not confirmed in our series. Therefore, clinicians should not rely on those characteristics in their decision-making on anti-EGFR re-tx, and adequate studies for implementing liquid biopsy in clinical practice are urgently needed.

Abstract
TPS4151 Background: Platinum/fluoropyrimidine regimens are the backbone of first-line therapy for advanced gastric cancer (AGC). The optimal duration of first-line therapy is still unknown and its continuation until disease progression represents the standard. However this strategy is often associated with cumulative toxicity and rapid development of drug resistance. Moreover, only 40% of AGC pts are eligible for second-line treatment. This study aims at assessing whether switch maintenance to ramucirumab plus paclitaxel will extend the progression-free survival (PFS) of subjects with HER-2 negative AGC who have not progressed after a first-line with a platinum/fluoropyrimidine regimen. The hypothesis is that the early administration of an active, non-cross resistant regimen may delay disease progression and, consequently, improve pts’ quality of life. This strategy may also rescue all those subjects that become ineligible for a second-line therapy due to the rapid clinical deterioration. Methods: This is a randomized, open-label, multicenter, phase III trial. Eligibility criteria are: unresectable/metastatic HER-2 negative AGC or gastroesophageal junction (GEJ) cancer; ECOG PS 0-1; measurable and/or evaluable disease by RECIST v1.1; no progression after 3 months of therapy with either FOLFOX4, mFOLFOX6 or XELOX . The primary endpoint is to compare PFS of pts in ARM A (continuation of the same first-line therapy with oxaliplatin/fluoropyrimidine) versus ARM B (switch maintenance to ramucirumab and placlitaxel). Secondary endpoints are: overall survival, time-to-treatment failure, overall response rate, duration of response, percentage of pts receiving a second-line therapy per treatment arm, safety and quality of life. Exploratory analyses to identify primary resistance and prognosis biomarkers are planned, including Next-Generation Sequencing (NGS) on archival tumor tissues. The ARMANI study is sponsored by the Fondazione IRCCS Istituto Nazionale dei Tumori and it is ongoing at 29 Italian centers with a planned population of 280 pts. Clinical trial information: NCT02934464.

Nivolumab (NIVO) + low-dose ipilimumab (IPI) as first-line (1L) therapy in microsatellite instability-high/DNA mismatch repair deficient (MSI-H/dMMR) metastatic colorectal cancer (mCRC): Clinical update. J Clin Oncol 2019.

Abstract
3521 Background: In the phase 2 CheckMate 142 trial, NIVO + low-dose IPI provided robust and durable clinical benefit and was well tolerated as 1L therapy for MSI-H/dMMR mCRC (Lenz et al. Ann Oncol 2018;29:LBA18). Longer follow-up data will be presented. Methods: Patients with MSI-H/dMMR mCRC and no prior treatment for metastatic disease received NIVO 3 mg/kg every 2 weeks + low-dose IPI 1 mg/kg every 6 weeks until disease progression or discontinuation. The primary endpoint was investigator-assessed objective response rate (ORR). Results: For all 45 patients (median follow-up was 13.8 months), ORR was 60% (95% CI 44.3–74.3). Responses were consistent with the overall population across subgroups including age, Eastern Cooperative Oncology Group (ECOG) performance status, prior adjuvant/neoadjuvant therapy, and mutation status (Table). Seven patients (16%) had grade 3–4 treatment-related adverse events (TRAEs); 3 (7%) had any grade TRAEs leading to discontinuation. Updated response, survival, and safety data after a longer follow-up (median 19.9 months) will be presented. Conclusions: NIVO + low-dose IPI demonstrated robust and durable clinical benefit and was well tolerated. Evaluated subgroups had responses consistent with the overall population. NIVO + low-dose IPI may represent a new 1L treatment option for patients with MSI-H/dMMR mCRC. Clinical trial information: NCT02060188. [Table: see text]
