Abstract
LBA5 Background: Neoadjuvant chemotherapy and radiation followed by surgical resection of the rectum is a standard treatment for locally advanced rectal cancer. A subset of rectal cancer is mismatch repair deficient. Since mismatch repair deficient colorectal cancer is responsive to PD-1 blockade in the metastatic setting, we hypothesized that locally advanced mismatch repair deficient rectal cancer is sensitive to checkpoint blockade and may alter the requirements for chemoradiotherapy and surgery. Methods: We conducted a prospective phase II study in which single agent dostarlimab, an anti PD-1 monoclonal antibody, was administered every 3 weeks for 6 months in patients with mismatch repair deficient stage II and III rectal adenocarcinoma, to be followed by standard chemoradiation and surgery. Patients who achieved a clinical complete response were eligible for omission of chemoradiation and surgery. Results: Twelve patients initiated treatment and have at least 6 months of follow up. All 12 (100%, 95% CI:74%-100%) achieved a clinical complete response with no evidence of tumor on MRI, FDG-PET, endoscopic visualization, digital rectal exam, or biopsy, which satisfied the study’s co-primary endpoint. To date, no patients have required chemoradiation or surgery, and no cases of progression or recurrence have been noted during follow up (range 6-25 months). No serious adverse events > grade 3 were observed. Conclusions: Mismatch repair deficient locally advanced rectal cancer is exceptionally sensitive to single agent PD-1 blockade. Longer follow up is needed to assess response duration. Clinical trial information: NCT04165772.

Abstract
3613 Background: Analysis of the IDEA database demonstrates significantly worse disease-free survival in high-risk stage III EO CRC vs AO CRC, regardless of adjuvant therapy intensity or duration. Critically this analysis omits somatic mutational data and germline status. Enrichment of TP53 in EO metastatic CRC (mCRC) is well described and functionality of individual TP53 mutations has been proposed as a potential mechanism of chemotherapy resistance. The prognostic and functional impact of somatic mutations merits analysis in the EO high-risk Stage III cohort. Methods: The Memorial Sloan Kettering MSKCC IMPACT database was queried for MSS Stage III AO CRC (≥50 yrs) and EO CRC ( < 50 yrs) patients(pts); clinico-pathological characteristics, systemic therapies received, and survival outcomes were reviewed. MSI, POLE mutated or hereditary syndrome associated tumors were excluded. We further classified TP53 mutations as GOF (gain of function) versus non GOF/ LOF (loss of function) (Pan M, JCO. 2022, Muller PA, Cancer cell. 2014). Results: 272 pts were included in the analysis (EO = 184, AO = 88). 50% of the EO and 62.5 % of the AO cohorts were male. Tumors were predominantly adenocarcinoma (EO 89% vs AO 91%), moderately differentiated (EO 78% vs AO 74%) and left sided (EO 77% vs AO 48.8%). 87% of the EO and 63.6 % of the AO cohort were TP53mut (p value 0.0003); TP53mut was enriched in the EO cohort regardless of sidedness but there was no significant difference in TP53 mutations between EO high vs low risk. Classifying by 7 putative GOF mutations (R175H, R248Q/W, R249S, R273H/L and R282W) 28.7% of the EO cohort harbored a GOF mutation vs 19.6% of the AO cohort. There was no statistically significant survival difference between pts with TP53mut tumors vs TP53 wild type (TP53wt) in the entire cohort (AO+EO) (p 0.041) or EO or AO cohorts (p 0.049). There was no significant difference in survival outcomes across all cohorts of TP53mut groups, both high and low risk, both GOF and non GOF, treated with 3 vs 6 months of chemotherapy (p 0.67). The EO TP53wt group was enriched relative to the EO TP53mut group for KRAS (60% vs 32%), BRAF (11% vs 4%), and PI3K driver alterations (PIK3CA, 20% vs 13%) and PTEN: (8% vs 3%) In the multivariate survival analysis of EO Stage III CRC BRAFmut status is highly statistically significant (p < 0.001). Conclusions: EO Stage III CRC is enriched for TP53 mutations regardless of sidedness and GOF mutations are identified in a higher proportion of EO CRC than AO CRC. We found no statistically significant difference in survival by TP53mut status across the entire MSS Stage III CRC cohort. There was no interaction between TP53mut status, duration of chemotherapy and overall survival. The functional impact of additional molecular features is being explored and the novel prognostic significance of BRAF demonstrated in this EO Stage III cohort requires further validation.

Abstract
3135 Background: MAPK1 encodes ERK2, a kinase component of the mitogen activated signaling (MAPK) pathway. ERK2 E322K is a known activating mutation that leads to increased phosphorylation and ERK signaling. In vitro studies found this mutation to be associated with resistance to dabrafenib, trametinib, but potential sensitivity to ERK inhibitors. Despite its potential as a drug target, little is known about the clinicopathologic characteristics of this hotspot mutation across solid tumors. Methods: Patients with solid tumors underwent tumor next-generation sequencing at Memorial Sloan Kettering Cancer Center between Jan 2015 and Sep 2020 using the MSK-IMPACT assay. Using the cBioPortal database and clinical charts, we analyzed tumors harboring MAPK1/ERK2 E322K mutations, assessed their clinicopathologic characteristics, co-mutational status and overall survival (OS). OS was measured from time of tumor sequencing to date of death or last follow-up. Results: A total of 37 tumor samples from 35 patients were identified in 59,822 tumors sequenced (0.06%) to harbor an ERK2 E322K mutation. The distribution across tumor types was as follows: head and neck squamous cell carcinoma (29%), bladder cancer (20%), lymphomas (9%), colorectal cancers (9%), gastric cancers (9%), cholangiocarcinoma (6%), cervical cancers (6%), lung cancers (6%), germ cell tumor (3%), Merkel cell carcinoma (3%), and breast cancers (3%). The OS in patients with metastatic disease and ERK2 E322K was 22.29 months (95%CI: 7.56-NA) months. Other mutations in RAS pathway frequently co-occurred with ERK2 E322K mutation (17/37, 46%). Concurrent mutations are also involved in pathways of cell cycle (71%), PI3K (71%), TP53 (66%), NOTCH (57%), RTK (51%), HIPPO (29%), TGF-beta (29%), WNT (26%), NRF2 (20%), MYC (14%). The median TMB score of samples from solid malignancies was 12.3 (range:0-101, quartiles: 6.9-33.0) mutation/Mb. Two patients (2/35, 6%) had microsatellite-instability high (MSI-H) tumors. The most frequent concurrent activating mutations include ARID1A (29%), FBXW7 (26%), PI3KCA (22%), PI3KR1/2/3 (20%), CDKN2A (11%), PTEN (8%), BRCA1/2(8%), FGFR3 (8%), BRAF (6%), Only one of these 35 patients received treatment targeting BRAF/MEK/ERK pathway and achieved partial response. One patient with NSCLC harboring a concurrent EGFR L858R mutation did not respond to erlotinib. One patient with PI3KCA mutated head and neck cancer did not respond to PI3K inhibitor. Two patients had TMB score of 100.9 and 12.9 mutation/Mb had partial response to pembrolizumab. Conclusions: ERK2 E322K mutation is a rare oncogenic mutation across diverse solid tumor types, associated with a high co-occurrence of other activating mutations and a high TMB. The lack of response to other targeted therapies suggests ERK2 E322K is a potential driver mutation. These findings may inform treatment and further development of ERK inhibitors.

Abstract
10505 Background: Lynch syndrome (LS) is caused by germline mutations in DNA mismatch repair genes and is characterized by microsatellite instability (MSI) status of associated tumors. MSI sensitizes tumors to immune checkpoint inhibition (ICI). The incidence of second primary malignancies and colonic polyps in LS patients with MSI tumors following ICI has not been evaluated. Methods: The Memorial Sloan Kettering LS database was queried for all patients with cancer who received ≥1 cycle of ICI using an IRB approved protocol. LS was confirmed by presence of a germline pathogenic/likely pathogenic alteration in a DNA mismatch repair gene ( MLH1, MSH2, MSH6, PMS2, EPCAM). Tumor and matched normal DNA sequencing was performed via MSK-IMPACT, an IRB approved protocol (NCT01775072). MSI status was assessed using MSIsensor. Results: At our center, 131 patients with LS received ICI mostly (73.3%) in the context of metastatic cancer. While 108 patients received ICI for an MSI tumor, 23 LS patients received ICI for a MSS (Microsatellite Stable) tumor (4 hepatobiliary, 3 colorectal, 3 CNS, 2 endometrial, 2 gastroesophageal, 2 renal, 2 sarcoma, 5 other). Five patients (3.8%) developed ≥1 second primary malignancy while on or following ICI comprised of an MSI small bowel adenocarcinoma, MSI upper tract urothelial cancer, 2 MSS prostate cancers, MSS HCC and MSI sebaceous neoplasm; 1 patient developed both MSS prostate cancer and MSI urothelial cancer on ICI. All five patients’ primary malignancy was MSI. Only a minority of patients underwent surveillance colonoscopies post completion of ICI (31.3%, (41/131)). Of these 41, nine (22%, (9/41)) were identified to have polyps including 8 tubular adenomas and 1 tubulo-villous adenoma. Median time to development of a polyp was 22 months (95% CI 16.82-27.18) from last colonoscopy and 13 months (95% CI 4-25 months) from last ICI. Notably amongst the 23 LS patients whose tumors were MSS, 14 had progression on ICI. Conclusions: Herein, we demonstrate that in LS-patients in receipt of ICI for cancer treatment, the risk of a second primary cancer and polyps remain high following treatment with ICI. Biological mechanisms underlying immune escape warrant further investigation. Surveillance strategies should be continued for LS patients post ICI.

Abstract
Background In the BEACON CRC study (NCT02928224), encorafenib plus cetuximab with binimetinib {9.3 versus 5.9 months; hazard ratio (HR) [95% confidence interval (CI)]: 0.60 [0.47-0.75]} or without binimetinib [9.3 versus 5.9 months; HR (95% CI): 0.61 (0.48-0.77)] significantly improved overall survival (OS) compared with the previous standard of care (control) in patients with BRAF V600E metastatic colorectal cancer (mCRC). Quality of life (QoL) was a secondary endpoint, assessed using validated instruments. Patients and methods BEACON CRC was a randomized, open-label, phase III study comparing encorafenib plus cetuximab with or without binimetinib and the investigator’s choice of irinotecan plus cetuximab or FOLFIRI plus cetuximab (chemotherapy control) in patients with previously treated BRAF V600E mCRC. Patient-reported QoL assessments included the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC) and Functional Assessment of Cancer Therapy—Colorectal (FACT-C). The primary outcome for these tools was time to definitive 10% deterioration. Results Encorafenib plus cetuximab, both with and without binimetinib, was associated with longer median times to definitive 10% deterioration versus the control group in the EORTC Global Health Status scale [HR (95% CI): 0.65 (0.52-0.80) versus 0.61 (0.49-0.75), respectively] and the FACT-C functional well-being subscale [HR (95% CI): 0.62 (0.50-0.76) versus 0.58 (0.47-0.72), respectively]. Consistent results were observed across all subscales of the EORTC and FACT-C instruments. QoL was generally maintained during treatment for the global EORTC and FACT-C scales. Conclusions In addition to improving OS, encorafenib plus cetuximab with or without binimetinib delays QoL decline in previously treated patients with BRAF V600E-mutant mCRC. BEACON CRC compares encorafenib + cetuximab ± binimetinib to chemotherapy in previously treated BRAF V600E mCRC. Encorafenib + cetuximab had longer time to 10% deterioration versus control in QoL and functional well-being scales. Encorafenib + cetuximab ± binimetinib delays QoL decline in previously treated patients with BRAF V600E mCRC.

Abstract
The TP53 gene is mutated in approximately 60% of all colorectal cancer (CRC) cases. Over 20% of all TP53-mutated CRC tumors carry missense mutations at position R175 or R273. Here we report that CRC tumors harboring R273 mutations are more prone to progress to metastatic disease, with decreased survival, than those with R175 mutations. We identify a distinct transcriptional signature orchestrated by p53R273H, implicating activation of oncogenic signaling pathways and predicting worse outcome. These features are shared also with the hotspot mutants p53R248Q and p53R248W. p53R273H selectively promotes rapid CRC cell spreading, migration, invasion and metastasis. The transcriptional output of p53R273H is associated with preferential binding to regulatory elements of R273 signature genes. Thus, different TP53 missense mutations contribute differently to cancer progression. Elucidation of the differential impact of distinct TP53 mutations on disease features may make TP53 mutational information more actionable, holding potential for better precision-based medicine.

Abstract
BACKGROUND Total neoadjuvant therapy (TNT) improves tumor response in locally advanced rectal cancer (LARC) patients compared to neoadjuvant chemoradiotherapy alone. The effect of TNT on patient survival has not been fully investigated. MATERIALS AND METHODS This was a retrospective case series of patients with LARC at a comprehensive cancer center. Three hundred and eleven patients received chemoradiotherapy (chemoRT) as the sole neoadjuvant treatment and planned adjuvant chemotherapy, and 313 received TNT (induction fluorouracil and oxaliplatin-based chemotherapy followed by chemoradiotherapy in the neoadjuvant setting). These patients then underwent total mesorectal excision or were entered in a watch-and-wait protocol. The proportion of patients with complete response (CR) after neoadjuvant therapy (defined as pathological CR or clinical CR sustained for 2 years) was compared by the χ2 test. Disease-free survival (DFS), local recurrence-free survival, distant metastasis-free survival, and overall survival were assessed by Kaplan-Meier analysis and log-rank test. Cox regression models were used to further evaluate DFS. RESULTS The rate of CR was 20% for chemoRT and 27% for TNT (P=.05). DFS, local recurrence-free survival, metastasis-free survival, and overall survival were no different. Disease-free survival was not associated with the type of neoadjuvant treatment (hazard ratio [HR] 1.3; 95% confidence interval [CI] 0.93-1.80; P = .12). CONCLUSIONS Although TNT does not prolong survival than neoadjuvant chemoradiotherapy plus intended postoperative chemotherapy, the higher response rate associated with TNT may create opportunities to preserve the rectum in more patients with LARC.

Abstract
BACKGROUND While 2-4% of lung cancers possess alterations in BRAF, little is known about the immune responsiveness of these tumours. METHODS Clinical and genomic data were collected from 5945 patients with lung cancers whose tumours underwent next-generation sequencing between 2015 and 2018. Patients were followed through 2020. RESULTS In total, 127 patients with metastatic BRAF-altered lung cancers were identified: 29 tumours had Class I mutations, 59 had Class II/III alterations, and 39 had variants of unknown significance (VUS). Tumour mutation burden was higher in Class II/III than Class I-altered tumours (8.8 mutations/Mb versus 4.9, P < 0.001), but this difference was diminished when stratified by smoking status. The overall response rate to immune checkpoint inhibitors (ICI) was 9% in Class I-altered tumours and 26% in Class II/III (P = 0.25), with median time on treatment of 1.9 months in both groups. Among patients with Class I-III-altered tumours, 36-month HR for death in those who ever versus never received ICI was 1.82 (1.17-6.11). Nine patients were on ICI for >2 years (two with Class I mutations, two with Class II/III alterations, and five with VUS). CONCLUSIONS A subset of patients with BRAF-altered lung cancers achieved durable disease control on ICI. However, collectively no significant clinical benefit was seen.

Abstract
PURPOSE Mitogen-activated protein kinase pathway-activating mutations occur in the majority of colorectal cancer (CRC) cases and show mutual exclusivity. We identified 47 epidermal growth factor receptor/BRAF inhibitor-naive CRC patients with dual RAS hotspot/BRAF V600E mutations (CRC-DD) from a cohort of 4,561 CRC patients with clinical next-generation sequencing results. We aimed to define the molecular phenotypes of the CRC-DD and to test if the dual RAS hotspot/BRAF V600E mutations coexist within the same cell. MATERIALS AND METHODS We developed a single-cell genotyping method with a mutation detection rate of 96.3% and a genotype prediction accuracy of 92.1%. Mutations in the CRC-DD cohort were analyzed for clonality, allelic imbalance, copy number, and overall survival. RESULTS Application of single-cell genotyping to four CRC-DD revealed the co-occurrence of both mutations in the following percentages of cells per case: NRAS G13D/KRAS G12C, 95%; KRAS G12D/NRAS G12V, 48%; BRAF V600E/KRAS G12D, 44%; and KRAS G12D/NRAS G13V, 14%, respectively. Allelic imbalance favoring the oncogenic allele was less frequent in CRC-DD (24 of 76, 31.5%, somatic mutations) compared with a curated cohort of CRC with a single-driver mutation (CRC-SD; 119 of 232 mutations, 51.3%; P = .013). Microsatellite instability-high status was enriched in CRC-DD compared with CRC-SD (23% v 11.4%, P = .028). Of the seven CRC-DD cases with multiregional sequencing, five retained both driver mutations throughout all sequenced tumor sites. Both CRC-DD cases with discordant multiregional sequencing were microsatellite instability-high. CONCLUSION Our findings indicate that dual-driver mutations occur in a rare subset of CRC, often within the same tumor cells and across multiple tumor sites. Their presence and a lower rate of allelic imbalance may be related to dose-dependent signaling within the mitogen-activated protein kinase pathway.

Abstract
360490 Background: KRAS mutation is present in 90% of pancreatic ductal adenocarcinomas with p.G12C accounting for 1% to 2% of these mutations. Sotorasib, a small molecule that specifically and irreversibly inhibits KRASG12C, has been investigated in the CodeBreaK100 trial in patients with KRASG12C-mutated advanced solid tumors. Herein, we report on the largest dataset evaluating efficacy and safety of a KRASG12C inhibitor in patients with pretreated KRASG12C-mutated pancreatic cancer. Methods: CodeBreaK100 (NCT03600883) is an international, single arm, phase I/II study evaluating the efficacy and safety of sotorasib in patients with KRASG12C-mutated advanced solid tumors with ≥ 1 prior systemic therapy unless intolerant or ineligible for available therapies. The primary efficacy endpoint is confirmed objective response rate (ORR), assessed by blinded independent central review (BICR) per RECIST 1.1. Secondary endpoints include duration of response (DoR), disease control rate (DCR), progression-free survival (PFS), and overall survival (OS). Results: As of November 1, 2021, 38 patients with pancreatic cancer (mean age: 65 years, 76.3% male) from the combined phase I/II study received sotorasib 960 mg once daily. Stage IV disease was present in 55.3% of patients at diagnosis, and in all patients at enrollment. Baseline ECOG scores were 0, 1, or 2 in 31.6%, 57.9%, and 10.5% of patients, respectively. Most patients (79%) had ≥ 2 prior lines of therapy (median: 2 [range: 1-8]). Median treatment duration was 4.1 months with a median follow-up of 16.8 months. Eight patients had confirmed partial response by BICR with a resulting ORR of 21.1% (95% CI: 9.55%-37.32%). DCR was 84.2% (Table 1). Treatment-related adverse events (TRAEs) of any grade occurred in 16 (42.1%) patients. Grade ≥ 3 TRAEs occurred in 6 patients: diarrhea (2); fatigue (2); abdominal pain, ALT increase, AST increase, pleural effusion, and pulmonary embolism (1 each). No TRAEs were fatal or resulted in sotorasib discontinuation. Conclusions: Sotorasib demonstrated clinically meaningful anticancer activity and tolerability in patients with heavily pretreated KRASG12C-mutated advanced pancreatic cancer, who have limited treatment options and poor prognosis. Clinical trial information: NCT03600883. [Table: see text]

Abstract
Metastatic progression is the main cause of death in cancer patients, whereas the underlying genomic mechanisms driving metastasis remain largely unknown. Here, we assembled MSK-MET, a pan-cancer cohort of over 25,000 patients with metastatic diseases. By analyzing genomic and clinical data from this cohort, we identified associations between genomic alterations and patterns of metastatic dissemination across 50 tumor types. We found that chromosomal instability is strongly correlated with metastatic burden in some tumor types, including prostate adenocarcinoma, lung adenocarcinoma, and HR+/HER2+ breast ductal carcinoma, but not in others, including colorectal cancer and high-grade serous ovarian cancer, where copy-number alteration patterns may be established early in tumor development. We also identified somatic alterations associated with metastatic burden and specific target organs. Our data offer a valuable resource for the investigation of the biological basis for metastatic spread and highlight the complex role of chromosomal instability in cancer progression.

Abstract
162 Background: In the randomized phase 3 BEACON study, encorafenib + binimetinib + cetuximab (triplet) and encorafenib + cetuximab (doublet) regimens improved overall survival (OS) and objective response rate (ORR) versus standard of care (control) in patients (pts) with previously treated BRAF V600E-mutant metastatic colorectal cancer. To identify whether detection of a BRAF V600E mutation in baseline circulating tumor DNA (ctDNA) correlated with response, we evaluated the status and allele frequency of BRAF V600E compared with clinical outcomes. Methods: Plasma samples were collected at Cycle 1 Day 1 and end of treatment for ctDNA analysis and analyzed using GuardantOMNI. Variant allele frequency (VAF) of BRAF V600E was grouped into high (> median) and low (≤median) categories. Low VAF samples included those where BRAF V600E mutation was not detected or no ctDNA was detected. ORR, based on blinded independent central review, and OS were compared between treatment arms according to VAF levels. ORR comparisons used Chi-square test and logistic regression. OS was summarized using the Kaplan-Meier method. HRs and 95% CIs were estimated using a Cox model. Additional correlation analyses between BRAF V600E status in baseline tumor tissue, as well as clonality, will be presented. Results: Baseline plasma samples were analyzed from 544 of 631 pts in the ctDNA analysis: 88.3% (196/222) in the triplet arm, 86.6% (187/216) in the doublet arm, and 83.4% (161/193) in the control arm. BRAF V600E mutations were detected in 90.4% (492/544) of pts (90.3% [177/196] triplet, 90.4% [169/187] doublet, and 90.7% [146/161] control). Pts with BRAF V600E mutations with high VAF had significantly ( P≤0.0001) increased ORR (95% CI) in the triplet and doublet arms (27.3% [19.5–36.8] and 15.9% [9.7–25.0], respectively) compared with control (0% [0.0–4.3]). Similar response trends were observed in pts with BRAF V600E mutations with low VAF (triplet: 28.9% [20.8–38.9]; doublet: 25.3% [17.7–34.6]; control: 5.3% [2.1–12.8]). OS decreased in BRAF V600E pts with high VAF (median OS [95% CI]: triplet 7.2 [6.0–8.0] months, n = 99; doublet 5.4 [4.4–6.1] months, n = 88; control 4.2 [3.4–4.8] months, n = 85) compared with pts with low VAF (triplet 14.8 [10.2–19.8] months, n = 97; doublet 14.8 [11.7–23.0] months, n = 99; control 9.3 [7.5–11.3] months, n = 76). Conclusions: ctDNA analyses showed the majority of pts in BEACON analyzed at baseline had a detectable BRAF V600E mutation. Increased response rates were observed in pts treated with triplet or doublet therapy compared with control, independent of VAF. Pts with a higher VAF for BRAF V600E may have a worse prognosis. Clinical trial information: NCT04607421.

Abstract
519 Background: KRAS, the most frequently mutated oncogene in cancer, is a key mediator of the RAS/MAPK signaling cascade that promotes cellular growth and proliferation. KRAS mutations occur in approximately 90% of pancreatic cancer, and approximately 2% of these are KRASG12C mutations. Adagrasib, an investigational agent, is a KRASG12C inhibitor that irreversibly and selectively binds KRASG12C, locking it in its inactive state; adagrasib has been optimized for favorable pharmacokinetic (PK) properties, including long half-life (̃24 h), extensive tissue distribution, dose-dependent PK, as well as CNS penetration. Methods: KRYSTAL-1 (NCT03785249) is a multicohort Phase 1/2 study evaluating adagrasib as monotherapy or in combinations in pts with advanced solid tumors harboring a KRASG12C mutation. Here we report preliminary data from pts enrolled in a Phase 2 cohort evaluating single-agent adagrasib administered orally at 600 mg BID in previously treated pts with unresectable or metastatic solid tumors (excluding NSCLC and CRC), including pancreatic and other GI cancers. Study endpoints include clinical activity, safety, and PK. Results: The data cutoff was 10 September 2021. A total of 42 pts were enrolled in this cohort (median age 63.5 years, range 21–89; 52% female; 71% white; 29%/71% ECOG PS 0/1; median 2 prior lines of therapy, range 1–7; median follow-up 6.3 months), of whom 30 pts had KRASG12C-mutant GI tumors (12 PDAC, 8 biliary tract, 5 appendiceal, 2 gastro-esophageal junction, 2 small bowel, and 1 esophageal). In a preliminary analysis, 27 pts with GI tumors were evaluable for clinical activity; partial responses (PRs) were seen in 41% (11/27, including 3 unconfirmed PRs); the disease control rate (DCR) was 100% (27/27). Of the 12 pts with PDAC (median 3 prior lines of therapy; median follow-up 8.1 months), 10 were evaluable for clinical activity; PRs were seen in 50% (5/10, including 1 unconfirmed PR); the DCR was 100% (10/10). Median progression-free survival (PFS) was 6.6 months (95% CI 1.0–9.7), and treatment was ongoing in 50% of pts with PDAC. Among the 17 evaluable pts with other GI tumors, 6 achieved PR (35%; 2 unconfirmed) with a DCR of 100% (17/17); 11 pts were still receiving treatment. In the overall cohort, treatment-related adverse events of any grade occurred in 91% (38/42), the most frequent being nausea (48%), diarrhea (43%), vomiting (43%), and fatigue (29%); grade 3/4 events occurred in 21% of pts, with no grade 5 events. Conclusions: Adagrasib monotherapy is well tolerated and demonstrates encouraging clinical activity in pretreated pts with PDAC and other GI tumors harboring a KRASG12C mutation. Further exploration of adagrasib is ongoing in this pt population (NCT03785249). Clinical trial information: NCT03785249.

Abstract
TPS214 Background: Approximately 3% of patients (pts) with CRC have the oncogenic Kirsten rat sarcoma viral oncogene homolog (KRAS) p.G12C mutation. Sotorasib, a small molecule that specifically and irreversibly inhibits the KRAS G12C mutant protein, has demonstrated modest clinical activity and no dose-limiting toxicities as a single agent in heavily pretreated pts with KRAS p.G12C-mutated CRC. The combination of sotorasib with other anticancer therapies, such as EGFR or MEK inhibitors, may enhance antitumor efficacy and counteract potential escape mechanisms. Other attractive partners for sotorasib in CRC include biologics and chemotherapy combinations. The CodeBreaK 101 master protocol is designed to evaluate safety, tolerability, pharmacokinetics (PK), and efficacy of multiple sotorasib-based combinations in pts with KRAS p.G12C mutated solid tumors. Key subprotocols with CRC combination treatment arms are highlighted here. Methods: This is a phase 1b, open-label study evaluating sotorasib alone and in combination regimens in pts with advanced KRAS p.G12C mutated CRC, NSCLC, and other solid tumors. Key regimens being explored in CRC include (1) Subprotocol A: Sotorasib + trametinib (MEK inhibitor) +/- panitumumab (EGFR inhibitor), (2) Subprotocol H: Sotorasib + panitumumab and sotorasib + panitumumab + FOLFIRI, and (3) Subprotocol M: Sotorasib + bevacizumab-awwb + FOLFIRI or FOLFOX. Key eligibility criteria include advanced or metastatic solid tumor with KRAS p.G12C mutation identified through molecular testing in treatment-naïve and pretreated patients depending on cohort. Primary endpoints include dose-limiting toxicities and treatment-emergent or treatment-related adverse events. Secondary endpoints include PK profile of combination regimens and efficacy (objective response, disease control, duration of response, time to response, and progression-free survival assessed per RECIST 1.1, and overall survival). Enrollment is ongoing. Contact Amgen Medical Information for more information: medinfo@amgen.com (NCT04185883). Abbreviations: EGFR = epidermal growth factor receptor; FOLFIRI = 5-fluorouracil + leucovorin + irinotecan; FOLFOX = 5-fluorouracil + leucovorin + oxaliplatin; MEK = mitogen-activated protein kinase.

Abstract
16 Background: Total neoadjuvant therapy with induction chemotherapy and chemoradiation (chemoRT) is the standard treatment for locally advanced rectal adenocarcinomas. Mismatch repair deficient (dMMR) rectal tumors respond poorly to neoadjuvant chemotherapy. PD-1 blockade is effective in patients with metastatic dMMR colorectal cancers, but its efficacy has not been established in the neoadjuvant setting. The purpose of this study is to evaluate the clinical benefit of neoadjuvant PD-1 blockade in dMMR locally advanced rectal cancer. Methods: We designed a prospective, single-arm, phase II study in which patients with stage II and III dMMR rectal cancer receive neoadjuvant dostarlimab (anti-PD-1) for a total of 6 months. The co-primary objectives are to determine the overall response rate (ORR) and pathologic complete response (pCR) or clinical complete response rate (cCR) with or without chemoRT. Tumor assessment with endoscopic evaluation is performed at baseline, 6 weeks, 3 months and 6 months; imaging is performed at pretreatment baseline, 3 months and 6 months. Patients with cCR by previously established criteria are eligible for non-operative management without chemoRT. Those with residual disease after neoadjuvant dostarlimab receive standard chemoRT. Following chemoRT, any patient failing to achieve a cCR is then managed surgically. Results: A total of 13 patients have been enrolled, with median age 52 years (range 26-78), 77% female, and 92% with node-positive disease by rectal MRI. The ORR is 100% in the 12 patients who have undergone at least a 3-month evaluation. Seven patients have completed induction therapy and all 7 (100%) have achieved a cCR and are undergoing observation without chemoRT or surgery. The rate of progressive disease thus far is 0%. No patients have required chemoRT or surgery. There have been no serious adverse events. Conclusions: Single agent neoadjuvant PD-1 blockade with dostarlimab is effective and well-tolerated in locally advanced dMMR rectal adenocarcinoma and allows patients to avoid chemoradiation and surgery. This suggests a potential new paradigm for treatment of dMMR locally advanced rectal cancer. Follow up and further patient accrual is ongoing. Clinical trial information: NCT04165772.

Abstract
134 Background: Currently, there are no 1L tx options indicated specifically for patients (pts) with BRAFV600E mCRC. Based on results of BEACON CRC (NCT02928224), BRAF inhibitor encorafenib + EGFR inhibitor cetuximab was approved for tx of previously treated pts with BRAFV600E mCRC. BREAKWATER (NCT04607421), an ongoing, open-label, global, multicenter, randomized phase 3 study, evaluates 1L EC ± chemotherapy for tx of pts with BRAFV600E mCRC. Here we present preliminary data on safety and pharmacokinetics (PK) from the BREAKWATER SLI, which aimed to identify the chemotherapy backbone for EC for the phase 3 portion of BREAKWATER. Methods: SLI inclusion criteria were BRAFV600E mCRC (determined using tumor tissue or blood); evaluable disease (RECIST v1.1); ≤1 prior systemic tx for mCRC; European Cooperative Oncology Group performance status (ECOG PS) 0/1; and adequate bone marrow, hepatic, and renal function. Pts previously treated with BRAF/EGFR inhibitors or both oxaliplatin and irinotecan were excluded. Pts received encorafenib 300 mg daily + cetuximab 500 mg/m2 every 2 weeks (Q2W) + either FOLFIRI Q2W or mFOLFOX6 Q2W in 28-day cycles. The primary endpoint was frequency of dose-limiting toxicities (DLTs). PK were a secondary endpoint. Data cutoff date: Sep 13, 2021. Results: 57 pts were enrolled (EC + FOLFIRI, n = 30; EC + mFOLFOX6, n = 27). Median (range) age was 57 (28–78) years; 25% were Asian; 65% had ECOG PS 0; 37% had ≥3 organs involved; 58% were treatment naive. At cutoff date, tx was ongoing in 45 (79%) pts. Median (range) duration of tx for encorafenib in EC + FOLFIRI and EC + mFOLFOX6 was 15 (0–31) and 14 (0–27) weeks, respectively. One DLT was observed: grade 4 neutropenia in 1 pt in EC + FOLFIRI. Tx-emergent all-cause serious adverse events (AEs) occurred in 20% and 19% and grade ≥3 AEs in 33% and 56% of pts in EC + FOLFIRI and EC + mFOLFOX6, respectively. The table shows frequent (all grade in ≥30% pts or grade ≥3 in ≥10% with either tx) tx-emergent all-cause AEs. One pt died due to disease progression. In EC + FOLFIRI, in the presence of steady-state encorafenib, AUCinf of irinotecan and its active metabolite, SN-38, significantly decreased ̃25% and ̃40%, respectively, compared with values in the absence of encorafenib. In EC + mFOLFOX6, oxaliplatin PK was not significantly altered by steady-state encorafenib. Conclusions: Based on these data, BREAKWATER phase 3 will compare EC ± mFOLFOX6 with mFOLFOX6/FOLFOXIRI/CAPOX ± bevacizumab. Clinical trial information: NCT04607421. [Table: see text]

Abstract
155 Background: Understanding the role of the tumor microenvironment in the response to chemotherapy and radiation in patients with locally advanced rectal cancer (LARC, stage II-III) can lead to the identification of novel immunologic biomarkers to preselect patients who can avoid surgery and benefit from watch-and-wait strategies. Methods: We performed DNA and RNA sequencing of pre-treatment biopsies from 89 LARC patients who received neoadjuvant therapy, including 5 microsatellite unstable (MSI) and 84 microsatellite stable (MSS) patients. We computed single-sample gene set enrichment analysis (ssGSEA) scores for immune infiltrates and signaling pathways implicated in tumor progression. Immunofluorescence and hematoxylin-eosin staining of tumor slides was performed to confirm significant correlations with RNA-Seq estimates of immune markers. Other genomic variables were also included in the analysis, such as tumor mutational burden (TMB), fraction of genome altered by copy number changes, whole genome duplication events and somatic mutations in rectal cancer driver genes and pathways. Results were largely replicated using an independent cohort of 42 LARC samples with publicly available data from The Cancer Genome Atlas (TCGA). Results: Since MSI tumors are known to have a distinct immunologic profile, we separated them into their own group and performed unsupervised hierarchical clustering on the MSS tumors. We identified a set of immune hot MSS tumors (n = 7) with extensive immune infiltration. These tumors had low TMB and were predominantly classified as CMS4 (5/7). None of the 12 patients in the combined MSI and immune hot MSS groups recurred during the length of our study and they had response rates > 50% (vs. < 25% in the rest of MSS patients). MSI and immune hot MSS tumors had lower frequency of TP53 and APC mutations, and they exhibited increased levels of T cell infiltration. In particular, we observed overexpression of markers for Th1 cells, which produce inflammatory cytokines (e.g., IFN-gamma) and are associated with antitumor immunity. Genes encoding protein targets of immune checkpoint blockade, such as PDCD1 (PD-1), CD274 (PD-L1), CTLA4, HAVCR2 (TIM3) and LAG3, were also overexpressed in the immune hot MSS and - to a lesser extent – the MSI tumors, suggesting that these patients might benefit from the use of immune checkpoint inhibitors. Conclusions: Our results uncover a unique LARC tumor immune profile evident in the pre-treatment setting that could be used to better prognosticate rectal cancer patients and develop novel therapeutic strategies.

Abstract
TPS211 Background: Approximately 10% of patients (pts) with mCRC have BRAF mutations (mostly V600E). First-line tx options for BRAFV600E mCRC are limited to cytotoxic chemotherapy ± anti-VEGF or anti-EGFR; or immune checkpoint inhibitors in pts with MSI-H tumors. In Europe, Japan, and USA, the combination of BRAF inhibitor enco + EGFR inhibitor cet is approved for tx of BRAFV600E mCRC after prior therapy. In BEACON CRC, enco + cet resulted in a median overall survival (OS) of 9.3 months (95% confidence interval [CI]: 8.0–11.3) and an objective response rate (ORR) of 19.5% (95% CI: 14.5%–25.4%) in previously treated pts with BRAFV600E mCRC (median follow-up: 12.8 months); 57.4% of pts had grade 3/4 adverse events (AEs), and 9% discontinued due to AEs. Given the poor prognosis of pts with BRAFV600E mCRC and based on the efficacy and tolerability of enco + cet from BEACON CRC, the BREAKWATER study will evaluate the efficacy and safety of enco + cet ± chemotherapy in tx-naive pts with BRAFV600E mCRC. Methods: BREAKWATER is an open-label, global, multicenter, randomized, phase 3 study with a safety lead-in (SLI). Approximately 60 and 870 pts will be enrolled in the SLI and phase 3 parts of the study, respectively. Pts must have mCRC with BRAF V600E-mutation (determined using tumor tissue or blood); ECOG performance status 0/1; and adequate bone marrow, hepatic, and renal function.

Abstract
Colorectal cancer is the second leading cause of cancer deaths worldwide, with a 5-year relative survival of 14% in patients with metastatic colorectal cancer (mCRC). Patients with BRAF V600E mutations, which occur in ∼10%-15% of patients with mCRC, have a poorer prognosis compared with those with wild-type BRAF tumours. The combination of the BRAF inhibitor encorafenib with the epidermal growth factor receptor inhibitor cetuximab currently represents the only chemotherapy-free targeted therapy approved in the USA and Europe for previously treated patients with BRAF V600E-mutated mCRC. As a class, BRAF inhibitors are associated with dermatologic, gastrointestinal, and renal events, as well as pyrexia and secondary skin malignancies. Adverse event (AE) profiles of specific BRAF inhibitors vary, however, and are affected by the specific agents given in combination. In patients with mCRC, commonly reported AEs of cetuximab monotherapy include infusion reactions and dermatologic toxicities. Data from the phase III BEACON CRC study indicate that the combination of encorafenib with cetuximab has a distinct safety profile. Here we review the most frequently reported AEs that occurred with this combination in BEACON CRC and best practices for managing and mitigating AEs that require more than standard supportive care.

Abstract
BACKGROUND The causative factors for the recent increase in early-onset colorectal cancer (EO-CRC) incidence are unknown. We sought to determine if early-onset disease is clinically or genomically distinct from average-onset colorectal cancer (AO-CRC). METHODS Clinical, histopathologic, and genomic characteristics of EO-CRC patients (2014-2019), divided into age 35 years and younger and 36-49 years at diagnosis, were compared with AO-CRC (50 years and older). Patients with mismatch repair deficient tumors, CRC-related hereditary syndromes, and inflammatory bowel disease were excluded from all but the germline analysis. All statistical tests were 2-sided. RESULTS In total, 759 patients with EO-CRC (35 years, n = 151; 36-49 years, n = 608) and AO-CRC (n = 687) were included. Left-sided tumors (35 years and younger = 80.8%; 36-49 years = 83.7%; AO = 63.9%; P < .001 for both comparisons), rectal bleeding (35 years and younger = 41.1%; 36-49 years = 41.0%; AO = 25.9%; P = .001 and P < .001, respectively), and abdominal pain (35 years and younger = 37.1%; 36-49 years = 34.0%; AO = 26.8%; P = .01 and P = .005, respectively) were more common in EO-CRC. Among microsatellite stable tumors, we found no differences in histopathologic tumor characteristics. Initially, differences in TP53 and Receptor Tyrosine Kinase signaling pathway (RTK-RAS)alterations were noted by age. However, on multivariate analysis including somatic gene analysis and tumor sidedness, no statistically significant differences at the gene or pathway level were demonstrated. Among advanced microsatellite stable CRCs, chemotherapy response and survival were equivalent by age cohorts. Pathogenic germline variants were identified in 23.3% of patients 35 years and younger vs 14.1% of AO-CRC (P = .01). CONCLUSIONS EO-CRCs are more commonly left-sided and present with rectal bleeding and abdominal pain but are otherwise clinically and genomically indistinguishable from AO-CRCs. Aggressive treatment regimens based solely on the age at CRC diagnosis are not warranted.

Abstract
BEACON CRC evaluated encorafenib plus cetuximab with or without binimetinib versus investigators' choice of irinotecan or FOLFIRI plus cetuximab in patients with BRAFV600E–mutant metastatic colorectal cancer (mCRC), after progression on 1-2 prior regimens. In the previously reported primary analysis, encorafenib, binimetinib plus cetuximab (ENCO/BINI/CETUX; triplet) and encorafenib plus cetuximab (ENCO/CETUX; doublet) regimens improved overall survival (OS) and objective response rate (ORR; by blinded central review) versus standard of care. The purpose of this analysis was to report updated efficacy and safety data.

Abstract
Abstract
PURPOSE: Alterations in the gut microbiome contribute to colorectal cancer (CRC) pathogenesis. The genotoxin colibactin, produced by pks+ E. coli, directly binds to DNA, leaving genetic scars at A-T rich motifs that can be identified by whole genome/exome sequencing (WGS/WES) as hexanucleotide mutation signatures SBS28 and SBS41. Here, we investigated whether MSK-IMPACT, a clinical targeted exon capture assay with lower genomic coverage (341-468 cancer associated exons), could be used to identify colibactin mutation signatures (CMS) and provide insight into associated clinicopathologic phenotypes.
METHODS: From an institutional pan-cancer cohort of 36,158 tumors assayed using MSK-IMPACT, we identified 11,864 samples (1,386 CRC) with at least 20 mutations and applied TempoSig, an algorithm which uses maximum likelihood-based extraction of mutational signature proportions. Tumors with at least 10% of all mutations attributed to SBS28/41 were deemed CMS+. Due to the association of POLE mutations and microsatellite instability with distinct phenotypes, we excluded these cases from our analysis.
RESULTS: Consistent with prior reports based on WGS/WES, our MSK-IMPACT TempoSig pipeline identified CMS positivity in multiple cancers, notably gastrointestinal (GI) and head and neck cancers. Ampullary tumors (25%) and GI neuroendocrine tumors (8%) had the highest SBS28 and SBS41 positivity respectively. Among microsatellite stable CRCs, we identified 52 patients with at least one sample positive for SBS28 (N=25) or SBS41 (N=27). Compared with CMS negative tumors, SBS28+ but not SBS41+ tumors had higher chromosomal instability as quantified by fraction of the genome altered by copy number alterations (SBS28+: 33.4% vs. SBS28-: 22.3%, P<.01), lower tumor mutation burden (SBS28+: 7.9/Mb vs. SBS28-: 8.8/Mb, P=.011), and a trend toward younger median age at sampling (57 (IQR 46-66) vs. 61 (IQR 51-70), P=.095). SBS28+ tumors harbored more frequent mutations in DNA damage repair (DDR) genes ATR (7.1 vs. 0.5%, P=.02) and ATM (14.3 vs. 4.1%, P=.03). Overall survival from diagnosis was decreased in patients with SBS28+ compared with SBS41+ tumors (22.0 vs. 43.7 months, P<.07), regardless of initial stage (P<.01). Histopathology revealed increased TILs in 13% of evaluable SBS28+ and 7% of SBS41+ tumors, while RNA FISH using a probe targeting the clbP gene required for colibactin synthesis was negative in all CMS+ samples, suggesting that colibactin mutagenesis is an early event not requiring persistent pks+ E. coli colonization.
CONCLUSIONS: TempoSig enables rigorous identification of colibactin mutation signatures in clinically utilized MSK-IMPACT targeted exon datasets. SBS28+ CRCs are clinically distinct and associated with early onset, poor prognosis and DDR pathway alterations. In ongoing studies, we are investigating the therapeutic implications of these findings.

Abstract
HSF1 promotes inflammation induced tumor development through ECM remodelingAbstractIn the colon, long-term exposure to chronic inflammation drives colitis associated colon cancer (CAC) in patients with inflammatory bowel disease (IBD). Chronic inflammation underlies tumor initiation, promotion, invasion, and metastasis. While the causal and clinical link between chronic inflammation and CAC is well established, we lack a molecular understanding of what is the way in which chronic inflammation leads to develop colon cancer. Within the tumor, cancer cells are surrounded by a variety of non-malignant cells, such as macrophages, endothelial cells, neutrophils, cancer-associated fibroblasts (CAFs), and together with the extracellular matrix (ECM) they compose the tumor microenvironment (TME), also termed the stroma. Even the most aggressive cancers depend and interact with their environment mostly through secreted factors. Unlike cancer cells, stromal cells are genomically stable, and do not harbor oncogenic mutations that could drive their co-evolution and functional reprogramming. Rather, stromal reprogramming is thought to be achieved by transcriptional rewiring. Previous work by us and others has shown that the master regulator heat shock factor 1 (HSF1) plays a crucial role in this process, by mediating a transcriptional program in fibroblasts that enables their reprogramming into cancer-associated fibroblasts (CAFs) to promote malignancy. We hypothesizde that HSF1 plays a crucial role in inflammation-driven cancer by initiation of a transcriptional program that leads to changes in the extracellular matrix (ECM). We found that, in cell culture, cancer-induced ECM assembly by fibroblasts requires HSF1. Using an inflammation-driven cancer model in mice, we measured the changes in proteomic and ECM organization over time. We found that HSF1 drives a transcriptional program that leads to ECM remodeling in early stages and results in development of colon cancer. Loss of HSF1 prevents inflammation-induced ECM remodeling. Further to that, in CAC patients, we found high activation of stromal HSF1 and similarity to our HSF1 proteomic ECM signature in human colorectal cancer driven by HSF1. Thus, HSF1-dependent ECM remodeling mediates the transition from chronic inflammation to colon cancer.

Abstract
3589 Background: HER2 amplified mCRC has emerged as a unique clinical subset, characterized by resistance to anti-EGFR therapy and response to anti-HER2 strategies. Accurate identification and quantification of HER2amp has predictive value for efficacy of anti-HER2 therapies and appropriate patient selection. Despite availability and use of various tumor tissue-based and blood-based assays for detecting HER2amp, data on cross-performance of these platforms are lacking. Methods: Leveraging a multicenter international consortium (Italy, Japan and USA), we generated a large cohort (N = 353) of mCRC patients (pts), tested for HER2amp using both tissue and blood. Tissue testing was done using immunohistochemistry (IHC), in-situ hybridization (ISH) and (NGS). ctDNA NGS was performed using CLIA-certified Guardant360 ctDNA assay, capable of detecting HER2 copy number (CN) variations. The primary endpoint was to correlate HER2 gene CNs in tissue (tCN) and plasma (pCN). Descriptive statistics, spearman correlation (r) and Fisher’s exact test were used. Results: Baseline tumors characteristics included right-sided primary in 234 (23%), proficient mismatch repair in 264 (98%) and RAS/BRAF wild type (WT) genotype in 194 (67%) pts. Tissue testing was done by IHC, ISH and NGS in 76%, 64% and 74% pts, respectively. A total of 177 pts had HER2amp detected by at least one test: 116 (66%), 157 (89%) and 96 (54%) of which had tissue +, ctDNA +, and both tissue and ctDNA + disease, respectively. Discordant cases consisted of 20 (6%) with positivity in tumor only and 61 (17%) in ctDNA only. Sensitivity, specificity, positive and negative predictive values of ctDNA assay (vis-à-vis tissue) were 83%, 74%, 61% and 90% respectively. Among HER2amp pts, median (range) HER2/CEP17 (ISH) ratio, tCN and pCN were 5.2 (2–12), 11.6 (2–700) and 3.5 (2–122), respectively. The pCN showed strong correlation with ISH ratio (r = 0.69) and tCN (r = 0.68) (P < 0.001). Median pCN differed significantly between pts with HER2 IHC 3+ (12.0), 2+ (2.2) and 0/1+ (2.0) tumors (P < 0.001). High HER2amp (pCN > 4.0) appeared to be enriched with tissue + cases (69% vs 8% [OR 24.6, P < 0.001]), tumor tissue HER2 + status (IHC3+ [75%] vs IHC2+ISH+ [50%] vs IHC2+/ISH- or IHC0/1+ [12%], P < 0.001), HER2 tCN > 6 (79% vs 31% [OR 8.7, P < 0.001]) and RAS/BRAF WT tumors (41% vs 17% [OR 3.5, P = 0.064) but not left sidedness (41% vs 38%; OR 1.1; P = 0.82). Conclusions: In this large diverse cohort of mCRC, we demonstrated correlation of HER2 tCN and pCN obtained by tissue-based and blood-based ctDNA assay. Further prospective efforts are needed to standardize this cross-platform quantification of HER2amp to facilitate robust clinical application of HER2 therapies. This effort shows the value of strategic international partnership in furthering research for rare cancer subsets.

Abstract
TPS3619 Background: Approximately 10% of patients (pts) with mCRC have BRAF mutations (mostly V600E). 1L tx options for BRAFV600E mCRC are limited to cytotoxic chemotherapy ± anti-VEGF or anti-EGFR, or immune checkpoint inhibitors in pts with MSI-H tumors. In Europe, Japan, and USA, the combination of BRAF inhibitor enco + EGFR inhibitor cetux is approved for tx of BRAFV600E mCRC after prior therapy. In BEACON CRC, enco + cetux resulted in a median overall survival (OS) of 9.3 months (95% confidence interval [CI]: 8.0–11.3) and an objective response rate (ORR) of 19.5% (95% CI: 14.5%–25.4%) in previously treated pts with BRAFV600E mCRC (median follow-up: 12.8 months); 57.4% of pts had grade 3/4 adverse events (AEs); 9% discontinued due to AEs. Given the poor prognosis of pts with BRAFV600E mCRC and based on the efficacy and tolerability of enco + cetux from BEACON CRC, BREAKWATER will evaluate efficacy and safety of enco + cetux ± chemotherapy in tx-naive pts with BRAFV600E mCRC. Methods: BREAKWATER is an open-label, global, multicenter, randomized, phase 3 study with a safety lead-in (SLI). Approximately 60 and 870 pts will be enrolled in the SLI and phase 3 parts of the study, respectively. Pts must have BRAFV600E mCRC (determined using tumor tissue or blood); ECOG performance status 0/1; and adequate bone marrow, hepatic, and renal function. Pts in the SLI must have evaluable disease (RECIST v1.1) and have received ≤ 1 prior tx regimen; those previously treated with a BRAF or EGFR inhibitor, or both oxaliplatin and irinotecan, will be excluded. Pts in the phase 3 study must have measurable disease and be tx naive for metastatic disease. Study tx and endpoints are shown in the table. Enrollment began on 6 January 2021. Clinical trial information: NCT04607421. [Table: see text]

Abstract
e16082 Background: Clonal hematopoiesis (CH) represents non-random clonal selection of bone marrow-derived cells marked by somatic mutations in certain genes. The presence of CH is associated with development of atherosclerosis and leukemia, and accelerated by toxic exposures (chemotherapy, radiation, smoking) and aging (Jaiswal et al. NEJM 2017; Abelson et al. Nature 2018). The impact of these genetic alterations on cellular function is unknown, especially in the broader context of immunity and in response to cancer therapy. To determine the contribution of CH to therapeutic response and hematologic toxicity in cancer patients, we examined the outcomes of patients treated with cytotoxic and immunotherapy in relationship to CH status. Methods: We evaluated patients with metastatic colorectal cancer (CRC) or esophagogastric cancer (EGC). DNA extracted from whole blood and tumor tissue were sequenced in tandem as part of the MSK-IMPACT hybridization capture-based sequencing assay. CH was defined as any mutation with a VAF of at least 2%, present in at least 10 reads, with at least 2:1 blood:tumor reads, or 1.5:1 blood:lymph node that was not found in gnomAD with a frequency > 0.005. Additional filtering and putative driver definitions (CH-PD) were described by Bolton et al. Nature Genetics 2020. Multivariate survival analyses were performed using a Cox Proportional Hazard model correcting for CH, CH-PD, prior smoking, prior chemotherapy, prior radiation, MSI status, and age at cancer diagnosis. Results: 654 patients with EGC (n = 348) and CRC (n = 306) who began treatment between 2006 and 2020 were included in the analysis. CH was present in 34.5% and 24.4% of each group, and 17.2% and 12.9% harbored CH-PD, respectively. CH and CH-PD were both associated with older age and smoking history, and CH was also associated with prior radiation and MSI-high status (p < 0.05). Patients with CH or CH-PD receiving first-line (1L) therapy for CRC or EGC demonstrated no difference in mPFS after multivariate analysis, though 1L EGC patients with CH-PD had inferior mOS (p = 9e-5). There was no difference in pre-1L WBC, ANC, or ALC, nor in G-CSF or PEG-G-CSF doses administered during 1L therapy between patients with CH or CH-PD versus those without. Similarly, presence of CH or CH-PD had no impact on mPFS or mOS in patients receiving immune checkpoint blockade (ICB) without concurrent chemotherapy after multivariate survival analysis. Conclusions: We confirmed that the mere presence of CH is not prognostic for overall survival, but that EGC patients with CH-PD mutations have inferior overall survival, which is consistent with previous findings. Presence of CH or CH-PD was not associated with differences in baseline leukocyte counts nor need for G-CSF support, nor did it impact PFS in either tumor type, suggesting limited utility of CH in solid tumor clinical decision-making.

Abstract
3583 Background: Enco + cetux (doublet) has been approved in the US, EU, and Japan for the treatment of BRAF V600E-mutant mCRC after progression on 1–2 prior regimens. In the BEACON CRC study (NCT02928224), median OS (95% CI) with the doublet was 9.3 months (8.0–11.3) compared with 5.9 months (5.1–7.1) with cetux + irinotecan or FOLFIRI (control) in patients (pts) with BRAF V600E-mutant mCRC (HR 0.61 [95% CI: 0.5–0.8]). This post-hoc analysis investigates OS by prior therapies to the doublet treatment in pts with BRAF V600E-mutant mCRC from the BEACON CRC study. Methods: OS of pts treated with the doublet or control were compared according to prior treatment with bevacizumab, oxaliplatin, or FOLFOXIRI and duration of prior anticancer therapy (ACT). Results: The proportion of pts in the doublet and control arms who received prior bevacizumab were 64% and 55%, respectively. Of pts who had one prior therapy, 95% and 88% received prior oxaliplatin and 20% and 14% received prior FOLFOXIRI, respectively. OS by prior treatment in the doublet and control arms is shown in the table. In the doublet arm, pts who had bevacizumab < 4 months before start of study treatment had a median OS of 8.3 months (95% CI: 6.2–11.2); those who had bevacizumab ≥4 months prior had a median OS of 10.7 (95% CI: 7.5–17.7). Within each treatment arm, OS was similar regardless of prior treatment with oxaliplatin or FOLFOXIRI. The duration of prior ACT was similar across study arms, ranging from 5.6–5.8 months for the first line of ACT. Conclusions: In the BEACON CRC study, pts treated with the doublet for BRAF V600E-mutant mCRC demonstrated similar OS regardless of prior therapies or duration of prior therapy use. This exploratory post-hoc analysis provides data that reflect the prior treatment landscape clinicians may face when deciding subsequent treatment regimens for pts with BRAF V600E-mutant mCRC. Clinical trial information: NCT02928224. [Table: see text]

Abstract
e15523 Background: The BRAF V600E mutation is a marker of poor prognosis in patients with mCRC. Targeted therapy, such as encorafenib + cetuximab, is approved in the US/Europe for the treatment of BRAF V600E-mutated mCRC and demonstrated improved survival vs historical standard of care (SOC). Determining BRAF mutation status in mCRC is recommended by NCCN and ESMO guidelines; although adherence to these guidelines may not be uniform. This report’s objective is to communicate global survey results of mCRC BRAF testing practices. Identifying regions where BRAF testing is not SOC may help identify where education efforts are needed to improve effective treatment decision making. Methods: Oncology treatment centers were identified from a registry and from public information. Centers were selected for research experience, historic data quality, and estimated numbers of mCRC patients. A BRAF testing practices survey using an online platform of verified centers was conducted from March to November 2020; 425 sites in 39 countries responded. Results: BRAF testing is performed as SOC most commonly in Northern and Western Europe (97%) and East Asia (95%). Conversely, BRAF testing as SOC is least common in Eastern Europe (47%) and South America (52%). Surveyed regions generally test patients when confirming advanced disease prior to first-line (1L) treatment (35% to 78%) or at initial histological diagnosis (9% to 41%). Most regions test tumor tissue; few test both tumor tissue and blood; and none conduct blood mutation testing only. Testing practices in the US by type of site (academic vs community) will be presented. Conclusions: BRAF testing has global variability, impacting treatment decisions. Increased awareness and routine testing may lead to informed decisions regarding targeted therapies, such as encorafenib + cetuximab (where approved), in patients with BRAF V600E-mutant mCRC.[Table: see text]

Abstract
TPS3614 Background: Anal cancer is growing in annual incidence globally and human papillomavirus (HPV) remains the predominant risk factor underlying its development. Due to its relative rarity, clinical trials in anal cancer have historically been difficult to conduct and treatment options for metastatic disease remain limited. Carboplatin/paclitaxel (CP) was compared to cisplatin/5-fluorouracil (historical standard of care) in a recent randomized phase II clinical trial (InterAACT; EA2133) in treatment-naïve metastatic anal cancer, finding that response rates were equivocal, but that overall survival (OS) was significantly longer in the CP arm (20 months vs 12.3 months, p = 0.014). Additionally, reduced grade 3/4 toxicities were seen in the CP arm. NCI9673, a single-arm phase II study, established safety and efficacy of nivolumab in previously-treated metastatic anal cancer. Progression-free survival (PFS) was 4.1 months (95% CI 3.0-7.9) and OS was 11.5 months (95% CI 7.1-not estimable). Multiple randomized trials in lung cancer have demonstrated efficacy of platinum-based chemotherapy combined with checkpoint inhibitors. Together these studies form the rationale behind combining CP and nivolumab in treatment-naïve metastatic anal cancer. Methods: EA2176 (NCT04444921) is the first NCTN phase III randomized clinical trial in treatment-naïve metastatic anal cancer. Stratification factors include HIV status and history of chemoradiation for curative intent. Patients will be randomized to carboplatin (AUC = 5, Day 1) plus paclitaxel (80mg/m2, Days 1, 8, 15) +/- nivolumab 240mg IV (Cycle 1 = Days 1, 15; Cycle ≥2 = Day 1, 480mg) q 28-days until disease progression or treatment intolerance. CP will be given for up to 6 cycles, while nivolumab will be continued as maintenance for up to 2 years. The primary endpoint is PFS. Secondary objectives include OS, response rate, and toxicity. Goal enrollment is 205 patients and the study continues accrual. This sample size will provide 80% power at a two-sided α of 0.05 to detect a 4.8-month improvement in PFS assuming 8 months in the control arm. Novel correlative studies include sequential quantitative tumor-derived cell-free HPV ctDNA levels (serotypes 16 and 18; Sysmex-Inostics SafeSEQ NGS assay). Correlative funding provided in part by the Farrah Fawcett Foundation and Sysmex Inostics, Inc. Clinical trial information: NCT04444921.

Abstract
12065 Background: With a rising incidence of younger patients diagnosed with rectal cancer, the long-term toxicity of cancer-related therapy is becoming even more relevant. Risk of SPM is a known potential consequence of both chemotherapy (chemo) and radiation therapy (RT), yet the rate of SPM in patients with rectal cancer is still not defined. We sought to further investigate factors associated with and outcomes of SPM after RT for rectal cancer. Methods: Patients diagnosed with stage II-III rectal cancer treated with chemo and/or RT from 1995-2019 were included in a retrospective study. Patients treated with palliative intent and those who survived < 5 years from treatment were excluded. RT-associated SPM was defined as a cancer occurring ³5 years after RT completion. Cumulative incidence (CI) of SPM was analyzed using a landmark analysis at 5 years with death as a competing risk. For patients with CT simulation scans available, dosimetric analyses evaluated doses to the organs developing SPM. Kaplan Meier analysis was used to evaluate overall survival among patients who developed an SPM. Results: A total of 2,700 patients were included (RT = 978; chemo = 1722). Demographic characteristics were equivalent apart from age, which was higher in the RT group (61 vs 59 years, p < 0.001). Five (0.3%) chemo patients developed an SPM, all within 5-10 years after treatment for rectal cancer, vs 48 (4.9%) RT patients. The 8-year CI of developing an SPM in the RT group was 4% (95% CI 2.4-6.2) and increased to 17% at 15 years (95% CI 12.1-21.8) and 21% at 20 years (95% CI 14.8-27.7). Most (89%) RT patients had received chemotherapy (most commonly 5-FU or FOLFOX). The median time to SPM was 108 months (interquartile range [IQR], 84-140). After pelvic RT, the most common SPM histology was endometrial (38%), followed by prostate (31%), bladder (23%), sarcoma (4.2%), and other gynecologic cancers (4.2%). Seven patients had CT simulations for dosimetric analyses: median of maximum dose to the organ with SPM was 5301cGy (IQR, 4928-5427), median of mean dose was 4551 cGy (IQR, 4476-4751). None of the patients who developed endometrial cancer had Lynch syndrome. Median OS for patients with SPM after RT was 5.1 years with 5-yr OS of 58% (95% CI 43-77); 44 out of 48 patients needed at least one treatment modality for their SPM, and 8 received trimodality treatment [surgery, chemo and RT]. Conclusions: The CI of SPM increased from 4% at 8 years to 17% at 15 years and 21% at 20 years following pelvic RT for rectal cancer. Endometrial cancer was the most common SPM and survival following treatment of SPM was favorable. These data serve as a foundation for future prospective studies evaluating ways to reduce SPM such as proton therapy.

Abstract
3513 Background: Encorafenib + binimetinib + cetuximab (enco/bini/cetux; triplet) and enco + cetux (doublet) regimens improved overall survival and objective response rate vs standard of care in pts with previously treated BRAF V600E-mutant mCRC in the randomized phase 3 BEACON study. To identify molecular correlates of clinical outcome, we performed molecular profiling in tumors from pts in the study. Methods: Baseline tumor samples were retrospectively analyzed by whole-exome sequencing (WES) and whole transcriptome sequencing (WTS) using ImmunoID NeXT (Personalis, Menlo Park, CA, USA). BRAF-mutant (BM) and consensus molecular subtypes (CMS) were determined using published classifiers. Pathway activities were evaluated with gene set variation analysis. Objective tumor response was evaluated according to each subtype. Additional association and interaction analyses between molecular features and clinical outcomes by treatments are ongoing and will be presented. Results: Baseline tumor samples were analyzed by WES and/or WTS from 527 of 665 (79.2%) randomized pts. The biomarker analyses set is representative of the total pt population and had similar clinical outcomes. Of the 460 pts analyzed by WTS (165/224 [73.7%] in the triplet arm, 146/220 [66.4%] in the doublet arm, and 149/221 [67.4%] in the control arm), 84.6% were classified as either CMS1 (n = 225) or CMS4 (n = 164). The proportion of pts classified as BM1 was 32.2% (n = 148) and the majority (84.5%) of these were CMS4, whereas many of those classified as BM2 (67.8%, n = 312) were CMS1 (64.7%). In the BM1 and CMS4 tumors, expression of inflammatory response and epithelial mesenchymal transition genes were elevated, and expression of cell cycle genes was reduced. The response rate in pts with CMS4 and/or BM1 tumors was higher in the triplet arm (CMS4: 33.3% [95% CI: 21.7–46.7]; BM1: 33.3% [95% CI: 21.4–47.1]) compared with the doublet arm (CMS4: 19.2% [95% CI: 9.6–32.5]; BM1: 14.9% [95% CI: 6.2–28.3]). Conclusions: Molecular characteristics and biological properties observed in BRAF V600E-mutant mCRC suggest that a subset of pts with specific molecular features may derive greater clinical benefit from triplet than doublet therapy. Additionally, these findings support the utility of gaining further understanding of the biological landscape in BRAF-mutant mCRC to enable potential hypotheses for pt selection to improve clinical outcome in future studies. Clinical trial information: NCT02928224.

Abstract
To characterize the relationship between tumor-infiltrating lymphocytes (TIL), tumor mutational burden (TMB), and genetic alterations in microsatellite stable (MSS), microsatellite instability (MSI), or mutant POLE/POLD1 colon cancer. MATERIALS AND METHODS Four hundred ninety-nine resected stage I-III colon tumors treated between 2014 and 2019 were assessed for TIL; somatic mutations, copy number alterations, and structural changes in > 400 oncogenes; and MSI status. RESULTS Of the 499 tumors analyzed, 313 were MSS, 175 were MSI, and 11 had POLE/POLD1 pathogenic mutations. Both the percentage of tumors with a high level of TIL (≥ 4 lymphocytes per high-power field) and the median TMB differed significantly between the three phenotypes: MSS, 4.5% and 6 mutations/Mb; MSI, 68% and 54 mutations/Mb; POLE/POLD1, 82% and 158 mutations/Mb (P < .05). Within each phenotype, TMB did not vary significantly with TIL level. Among MSI tumors, the median number of frameshift indels was significantly higher in tumors with high levels of TIL (20 v 17; P = .018). In the MSS group, significantly higher proportions of tumors with high levels of TIL had mutations in the transforming growth factor-β (36% v 12%; P = .01), RAS (86% v 54%; P = .02), and Hippo (7% v 1%; P = .046) pathways; in contrast, TP53 alterations were associated with low levels of TIL (74% v 43%; P = .01). CONCLUSION The association between TIL, TMB, and genetic alterations varies significantly between MSI, MSS, and mutant POLE/POLD1 colon tumors. These differences may help explain tumoral immunity and lead to predictors of response to immunotherapy.

Abstract
BACKGROUND EGFR amplification occurs in about 1% of metastatic colorectal cancers (mCRCs) but is not routinely tested as a prognostic or predictive biomarker for patients treated with anti-EGFR monoclonal antibodies (mAbs). Herein, we aimed to characterize the clinical and molecular landscape of EGFR-amplified metastatic colorectal cancer (mCRC). METHODS In this multinational cohort study, we compared clinical data of 62 patients with EGFR-amplified vs. 1459 EGFR non-amplified mCRC, as well as comprehensive genomic data of 35 EGFR-amplified vs. 439 EGFR non-amplified RAS/BRAF wild-type and microsatellite stable (MSS) tumor samples. RESULTS EGFR amplification was statistically significantly associated with left primary tumor sidedness and RAS/BRAF wild-type status. All EGFR-amplified tumors were MSS and HER2 non-amplified. Overall, EGFR-amplified samples had higher median fraction of genome altered compared to EGFR non-amplified, RAS/BRAF wild-type MSS cohort. Patients with EGFR-amplified tumors reported longer overall survival (OS) (median OS = 71.3 months; 95% confidence interval [CI] = 50.7-NA) vs. EGFR non-amplified ones (24.0 months; 95% CI = 22.8-25.6; hazard ratio [HR] = 0.30, 95% CI = 0.20-0.44, P<.001; adjusted HR = 0.46, 95%CI = 0.30-0.69, P<.001). In the subgroup of patients with RAS/BRAF wild-type mCRC exposed to anti-EGFR-based therapy, EGFR amplification was again associated with better OS (median OS = 54.0 months [95% CI = 35.2-NA] vs. 29.1 months [95% CI = 27.0-31.9], respectively; HR = 0.46, 95%CI = 0.28-0.76, P=.002). CONCLUSION Patients with EGFR-amplified mCRC represent a biologically defined subgroup and merit dedicated clinical trials with novel and more potent EGFR targeting strategies beyond single-agent monoclonal antibodies.

Abstract
PURPOSE KRAS G12C is the most common KRAS mutation in primary lung adenocarcinoma. Phase I clinical trials have demonstrated encouraging clinical activity of KRAS G12C inhibitors in the metastatic setting. We investigated disease-free survival (DFS) and tumor genomic features in patients with surgically resected KRAS G12C-mutant lung adenocarcinoma. EXPERIMENTAL DESIGN Patients who underwent resection of stage I-III lung adenocarcinoma and next-generation sequencing (NGS) were evaluated. Exclusion criteria were receipt of induction therapy, incomplete resection, and low-quality NGS. Mutations were classified as KRAS wild-type (KRAS wt), G12C (KRAS G12C), or non-G12C (KRAS other). DFS was compared between groups using the log-rank test; factors associated with DFS were assessed using Cox regression. Mutual exclusivity and cooccurrence, tumor clonality, and mutational signatures were assessed. RESULTS In total, 604 patients were included: 374 KRAS wt (62%), 95 KRAS G12C (16%), and 135 KRAS other (22%). Three-year DFS was not different between KRAS-mutant and KRAS wt tumors. However, 3-year DFS was worse in patients with KRAS G12C than KRAS other tumors (log-rank P = 0.029). KRAS G12C tumors had more lymphovascular invasion (51% vs. 37%; P = 0.032) and higher tumor mutation burden [median (interquartile range), 7.0 (5.3-10.8) vs. 6.1 (3.5-9.7); P = 0.021], compared with KRAS other tumors. KRAS G12C mutation was independently associated with worse DFS on multivariable analysis. Our DFS findings were externally validated in an independent The Cancer Genome Atlas cohort. CONCLUSIONS KRAS G12C mutations are associated with worse DFS after complete resection of stage I-III lung adenocarcinoma. These tumors harbor more aggressive clinicopathologic and genomic features than other KRAS-mutant tumors. We identified a high-risk group for whom KRAS G12C inhibitors may be investigated to improve survival.

Abstract
Lynch syndrome is a heritable cancer syndrome caused by a heterozygous germline mutation in DNA mismatch repair (MMR) genes. MMR-deficient (dMMR) tumors are particularly sensitive to immune checkpoint inhibitors, an effect attributed to the higher mutation rate in these cancers. However, approximately 15% to 30% of patients with dMMR cancers do not respond to immunotherapy. This report describes 3 patients with Lynch syndrome who each had 2 primary malignancies: 1 with dMMR and a high tumor mutational burden (TMB), and 1 with dMMR but, unexpectedly, a low TMB. Two of these patients received immunotherapy for their TMB-low tumors but experienced no response. We have found that not all Lynch-associated dMMR tumors have a high TMB and propose that tumors with dMMR and TMB discordance may be resistant to immunotherapy. The possibility of dMMR/TMB discordance should be considered, particularly in less-typical Lynch cancers, in which TMB evaluation could guide the use of immune checkpoint inhibitors.

Abstract
PURPOSE Immune checkpoint inhibition (ICI) alone is not active in mismatch repair-proficient (MMR-P) metastatic colorectal cancer (mCRC), nor does radiotherapy alone result in objective systemic benefit. However, combined radiotherapy plus ICI can induce systemic antitumor immunity in preclinical and clinical models. PATIENTS AND METHODS In this single-center, phase II study, patients with chemotherapy-refractory MMR-P mCRC received durvalumab 1,500 mg plus tremelimumab 75 mg every 4 weeks plus radiotherapy. The primary endpoint was objective response rate (ORR) in nonirradiated lesions. Treatment and efficacy were correlated with peripheral immune cell profiles. RESULTS We enrolled 24 patients, and report outcomes after a median follow-up of 21.8 (range: 15.9-26.3) months. The ORR was 8.3% (2 patients) [95% confidence interval (CI), 1.0-27.0]. The median progression-free survival was 1.8 (95% CI, 1.7-1.9) months, median overall survival was 11.4 (95% CI, 10.1-17.4) months. Twenty five percent of patients (n = 6) had treatment-related grade 3-4 adverse events. We observed increased circulating CD8+ T lymphocyte activation, differentiation, and proliferation in patients with objective response. CONCLUSIONS This combination of radiotherapy plus ICI study did not meet the prespecified endpoint criteria to be considered worthwhile for further study. However, rare instances of systemic immune augmentation and regression in nonirradiated lesions were observed (an abscopal response). Combination durvalumab and tremelimumab plus radiotherapy is feasible in MMR-P mCRC with a manageable safety profile. Further studies of novel immunotherapy combinations, and identification of biomarkers predictive of abscopal response are warranted.

Abstract
128 Background:The BRAF V600E mutation is a marker of poor prognosis in patients with metastatic colorectal cancer (mCRC). Targeted therapy, such as encorafenib plus cetuximab, is approved in the US/Europe for the treatment (tx) of BRAF V600E-mutated mCRC and demonstrated improved survival vs historical standard of care (SOC). Determining BRAF mutation status in mCRC is recommended by NCCN and ESMO guidelines although adherence to guidelines may not be uniform. This report’s objective is to communicate global survey results of mCRC BRAF testing practices. Identifying regions where BRAF testing is not SOC may help identify where education efforts are needed improve effective tx decision making. Methods: Oncology tx centers were identified from a registry and public information. Centers were selected for research experience, historic data quality, and estimated mCRC patients. A BRAF testing practices survey using an online platform of verified centers was conducted March-August 2020; 395 centers/38 countries have responded thus far. Results: Respondents indicated BRAF-mutation testing is performed as SOC for patients with mCRC in most regions; Eastern Europe and South America are exceptions: only 47% (45/95) and 45% (9/20) of centers, respectively routinely performed mutation testing. Most test tumor tissue, few test both tumor tissue or blood, and none conduct blood mutation testing only. Most regions perform BRAF testing at initial diagnosis or confirmation of advanced disease. Individual country statistics will be presented. Conclusions: BRAF testing has global variability, impacting tx decisions. Increased awareness and routine testing may lead to informed decisions regarding targeted therapies, such as encorafenib plus cetuximab where approved, in patients with BRAF V600E-mutant mCRC.

Abstract
PURPOSE Clinical calculators and nomograms have been endorsed by the American Joint Committee on Cancer (AJCC), as they provide the most individualized and accurate estimate of patient outcome. Using molecular and clinicopathologic variables, a third-generation clinical calculator was built to predict recurrence following resection of stage I-III colon cancer. METHODS Prospectively collected data from 1,095 patients who underwent colectomy between 2007 and 2014 at Memorial Sloan Kettering Cancer Center were used to develop a clinical calculator. Discrimination was measured with concordance index, and variability in individual predictions was assessed with calibration curves. The clinical calculator was externally validated with a patient cohort from Washington University's Siteman Cancer Center in St Louis. RESULTS The clinical calculator incorporated six variables: microsatellite genomic phenotype; AJCC T category; number of tumor-involved lymph nodes; presence of high-risk pathologic features such as venous, lymphatic, or perineural invasion; presence of tumor-infiltrating lymphocytes; and use of adjuvant chemotherapy. The concordance index was 0.792 (95% CI, 0.749 to 0.837) for the clinical calculator, compared with 0.708 (95% CI, 0.671 to 0.745) and 0.757 (0.715 to 0.799) for the staging schemes of the AJCC manual's 5th and 8th editions, respectively. External validation confirmed robust performance, with a concordance index of 0.738 (95% CI, 0.703 to 0.811) and calibration plots of predicted probability and observed events approaching a 45° diagonal. CONCLUSION This third-generation clinical calculator for predicting cancer recurrence following curative colectomy successfully incorporates microsatellite genomic phenotype and the presence of tumor-infiltrating lymphocytes, resulting in improved discrimination and predictive accuracy. This exemplifies an evolution of a clinical calculator to maintain relevance by incorporating emerging variables as they become validated and accepted in the oncologic community.

Abstract
Focal chromosomal amplification is an important route to generating cancer through mediating over-expression of oncogenes1–3 or to developing cancer therapy resistance by increasing expression of a gene whose action diminishes efficacy of an anti-cancer drug. Here we used whole-genome sequencing of clonal isolates developing chemotherapeutic resistance to identify chromothripsis as a major driver of extrachromosomal DNA (ecDNA) amplification into circular double minutes (DMs) through PARP- and DNA-PKcs-dependent mechanisms. Longitudinal analyses revealed that DMs undergo continuing structural evolution to promote increased drug tolerance through additional chromothriptic events. In-situ Hi-C sequencing is used to demonstrate that DMs preferentially tether near chromosome ends where they re-integrate when DNA damage is present. Intrachromosomal amplifications formed initially under low-level drug selection undergo continuing breakage-fusion-bridge cycles, generating >100 megabase-long amplicons that we show become trapped within interphase bridges and then shattered, producing micronuclei that mediate DM formation. Similar genome rearrangement profiles linked to localized gene amplification are identified in human cancers with acquired drug resistance or with oncogene amplifications. We propose that chromothripsis is a primary mechanism accelerating genomic DNA amplification and which enables rapid acquisition of tolerance to altered growth conditions.

Abstract
In the colon, long-term exposure to chronic inflammation drives colitis-associated colon cancer (CAC) in patients with inflammatory bowel disease. While the causal and clinical links are well established, molecular understanding of how chronic inflammation leads to the development of colon cancer is lacking. Here we deconstruct the evolving microenvironment of CAC by measuring proteomic changes and extracellular matrix (ECM) organization over time in a mouse model of CAC. We detect early changes in ECM structure and composition, and report a crucial role for the transcriptional regulator heat shock factor 1 (HSF1) in orchestrating these events. Loss of HSF1 abrogates ECM assembly by colon fibroblasts in cell-culture, prevents inflammation-induced ECM remodeling in mice and inhibits progression to CAC. Establishing relevance to human disease, we find high activation of stromal HSF1 in CAC patients, and detect the HSF1-dependent proteomic ECM signature in human colorectal cancer. Thus, HSF1-dependent ECM remodeling plays a crucial role in mediating inflammation-driven colon cancer.

Abstract
An increasing number of studies are describing potential uses of circulating tumour DNA (ctDNA) in the care of patients with colorectal cancer. Owing to this rapidly developing area of research, the Colon and Rectal-Anal Task Forces of the United States National Cancer Institute convened a panel of multidisciplinary experts to summarize current data on the utility of ctDNA in the management of colorectal cancer and to provide guidance in promoting the efficient development and integration of this technology into clinical care. The panel focused on four key areas in which ctDNA has the potential to change clinical practice, including the detection of minimal residual disease, the management of patients with rectal cancer, monitoring responses to therapy, and tracking clonal dynamics in response to targeted therapies and other systemic treatments. The panel also provides general guidelines with relevance for ctDNA-related research efforts, irrespective of indication.

Abstract
Background Deriving individual tumor genomic characteristics from patient imaging analysis is desirable. We explore the predictive value of 2-[18F]FDG uptake with regard to the KRAS mutational status of colorectal adenocarcinoma liver metastases (CLM). Methods 2-[18F]FDG PET/CT images, surgical pathology and molecular diagnostic reports of 37 patients who underwent PET/CT-guided biopsy of CLM were reviewed under an IRB-approved retrospective research protocol. Sixty CLM in 39 interventional PET scans of the 37 patients were segmented using two different auto-segmentation tools implemented in different commercially available software packages. PET standard uptake values (SUV) were corrected for: (1) partial volume effect (PVE) using cold wall-corrected contrast recovery coefficients derived from phantom spheres with variable diameter and (2) variability of arterial tracer supply and variability of uptake time after injection until start of PET scan derived from the tumor-to-blood standard uptake ratio (SUR) approach. The correlations between the KRAS mutational status and the mean, peak and maximum SUV were investigated using Student’s t test, Wilcoxon rank sum test with continuity correction, logistic regression and receiver operation characteristic (ROC) analysis.
These correlation analyses were also performed for the ratios of the mean, peak and maximum tumor uptake to the mean blood activity concentration at the time of scan: SURMEAN, SURPEAK and SURMAX, respectively. Results Fifteen patients harbored KRAS missense mutations (KRAS+), while another 3 harbored KRAS gene amplification. For 31 lesions, the mutational status was derived from the PET/CT-guided biopsy. The Student’s t test p values for separating KRAS mutant cases decreased after applying PVE correction to all uptake metrics of each lesion and when applying correction for uptake time variability to the SUR metrics. The observed correlations were strongest when both corrections were applied to SURMAX and when the patients harboring gene amplification were grouped with the wild type: p ≤ 0.001; ROC area under the curve = 0.77 and 0.75 for the two different segmentations, respectively, with a mean specificity of 0.69 and sensitivity of 0.85. Conclusion The correlations observed after applying the described corrections show potential for assigning probabilities for the KRAS missense mutation status in CLM using 2-[18F]FDG PET images.

Abstract
PURPOSE The prevalence and clinical characteristics of small bowel adenocarcinomas (SBA) in the setting of Lynch syndrome have not been well studied. We characterized SBA according to DNA mismatch repair and/or microsatellite instability (MMR/MSI) and germline mutation status and compared clinical outcomes. EXPERIMENTAL DESIGN A single-institution review identified 100 SBAs. Tumors were evaluated for MSI via MSIsensor and/or corresponding MMR protein expression via IHC staining. Germline DNA was analyzed for mutations in known cancer predisposition genes, including MMR (MLH1, MSH2, MSH6, PMS2, and EPCAM). Clinical variables were correlated with MMR/MSI status. RESULTS Twenty-six percent (26/100; 95% confidence interval, 18.4-35.4) of SBAs exhibited MMR deficiency (MMR-D). Lynch syndrome prevalence was 10% overall and 38.5% among MMR-D SBAs. Median age at SBA diagnosis was similar in non-Lynch syndrome MMR-D versus MMR-proficient (MMR-P) SBAs (65 vs. 61; P = 0.75), but significantly younger in Lynch syndrome (47.5 vs. 61; P = 0.03). The prevalence of synchronous/metachronous cancers was 9% (6/67) in MMR-P versus 34.6% (9/26) in MMR-D SBA, with 66.7% (6/9) of these in Lynch syndrome (P = 0.0002). In the MMR-P group, 52.2% (35/67) of patients presented with metastatic disease, compared with 23.1% (6/26) in the MMR-D group (P = 0.008). In MMR-P stage I/II patients, 88.2% (15/17) recurred, compared with 18.2% (2/11) in the MMR-D group (P = 0.0002). CONCLUSIONS When compared with MMR-P SBA, MMR-D SBA was associated with earlier stage disease and lower recurrence rates, similar to observations in colorectal cancer. With a 38.5% prevalence in MMR-D SBA, germline Lynch syndrome testing in MMR-D SBA is warranted.

Abstract
Tumor infiltrating lymphocytes (TIL), which represent host adaptive response to the tumor, were first identified at scanning magnification to select areas with the highest counts on hematoxylin and eosin slides, quantitated per high-power field (HPF), and analyzed for association with recurrence-free survival (RFS) in 848 patients. Highest TIL in a single HPF was analyzed as a continuous and categorical variable, and optimal cutoff analysis was performed to predict RFS. Highest TIL count in a single HPF ranged from 0 to 45, and the optimal cutoff for TIL high vs TIL low was determined to be ≥ 3 vs < 3 with a concordance probability estimate of 0.74. In the entire cohort, 5-year RFS was 90.2% (95% CI = 83.7–94.2) in TIL high compared to 78.9% (95% CI = 74.1–82.9) in TIL low (log rank P < .0001). TIL remained significant in the mismatch repair-proficient (pMMR) cohort where 5-year RFS was 94.6% (95% CI = 88.3–97.5) in TIL high compared to 77.9% (95% CI = 69.2–84.4) in TIL low (P = .008). On multivariable analysis, TIL and AJCC Stage were independently associated with RFS in the pMMR cohort. Qualitatively in the pMMR cohort, RFS in Stage II TIL high patients was similar to that in Stage I patients and RFS in Stage III TIL high was similar to that in Stage II TIL low patients. Assessment of TIL in a single HPF using standard H&E slides provides important prognostic information independent of MMR status and AJCC stage.
