TPS467 Background: Gastroesophageal adenocarcinoma patients with metastatic lymph nodes (ypN+) or a microscopically incomplete surgical resection (R1) following neoadjuvant chemotherapy are at high risk of disease recurrence. Current practice is to continue with the same perioperative chemotherapy used prior to surgery, despite these suboptimal outcomes. Immune checkpoint blockade with nivolumab and ipilimumab has demonstrated activity in advanced gastroesophageal adenocarcinoma. We hypothesise that high risk (ypN+ and/or R1) post resection gastroesophageal adenocarcinoma patients who are treated with nivolumab and ipilimumab will have better disease free survival than patients who continue with standard post-operative chemotherapy. Methods: VESTIGE is an ongoing, international, open label randomized phase II study designed to evaluate the efficacy of adjuvant nivolumab plus ipilimumab versus standard post-operative chemotherapy in high risk (ypN+ and/or R1) post resection gastroesophageal adenocarcinoma patients. Eligible patients (n=240) will be randomised 1:1 to receive post-operative adjuvant chemotherapy (identical regimen as pre-operatively) or nivolumab 3mg/kg IV q2w plus ipilimumab 1mg/kg IV q6w x 1 year. Key inclusion criteria include ypN+ and/or R1 status following neoadjuvant chemotherapy plus surgery and an adequate pre-specified surgical resection. The primary endpoint of the study is disease free survival, with secondary endpoints of overall survival, safety, toxicity and quality of life. The trial will recruit 240 patients at 24 number of sites in the Czech Republic, France, Germany, Israel, Italy, Norway, Poland, Portugal, Spain, and United Kingdom. Recruitment commenced July 2019 and is anticipated to take 30 months. The VESTIGE translational research programme includes collection of pre-treatment biopsies, post-chemotherapy resection specimens and serial liquid biopsy on treatment to explore biomarkers predictive of immune checkpoint blockade efficacy. Clinical trial information: NCT03443856.

TPS4156 Background: Gastroesophageal adenocarcinoma (GEA) patients with metastatic lymph nodes (ypN+) or a microscopically incomplete surgical resection (R1) following neoadjuvant chemotherapy are at high risk of disease recurrence. Current practice is to continue with the same perioperative chemotherapy used prior to surgery, despite these suboptimal outcomes. Adjuvant immunotherapy with nivolumab has shown efficacy in poor risk GEA patients following chemoradiotherapy and surgery in the CheckMate 577 trial, and nivolumab and ipilimumab have demonstrated activity in advanced GEA. We hypothesise that high risk (ypN+ and/or R1) post resection GEA patients who are treated with nivolumab and ipilimumab will have better disease free survival than patients who continue with standard post-operative chemotherapy. Methods: VESTIGE is an ongoing, international, open label randomized phase II study designed to evaluate the efficacy of adjuvant nivolumab plus ipilimumab versus standard post-operative chemotherapy in high risk (ypN+ and/or R1) post resection GEA patients. Eligible patients (n=240) will be randomised 1:1 to receive post-operative adjuvant chemotherapy (identical regimen as pre-operatively) or nivolumab 3mg/kg IV q2w plus ipilimumab 1mg/kg IV q6w x 1 year. Key inclusion criteria include ypN+ and/or R1 status following neoadjuvant chemotherapy plus surgery and an adequate pre-specified surgical resection. The primary endpoint of the study is disease free survival, with secondary endpoints of overall survival, safety, toxicity and quality of life. Since start of recruitment in August 2019, the trial has recruited 85 of 240 patients at 18 sites in the Czech Republic, France, Germany, Israel, Italy, Norway, Poland, Spain, and United Kingdom. The VESTIGE translational research programme includes collection of pre-treatment biopsies, post-chemotherapy resection specimens and serial liquid biopsy on treatment to explore biomarkers predictive of immune checkpoint blockade efficacy.

122 Background: This phase II study was aimed to define the pathological response rate and safety of combining weekly nab-paclitaxel and cisplatin as neoadjuvant chemotherapy in pts with locally advanced esophageal SCC. Methods: Pts with resectable locally advanced thoracic esophageal SCC staged by EUS, CT and/or PET-CTscan. All pts received nab-paclitaxel (100 mg/m2, d1, d8, d22 and d29) and cisplatin (75 mg/m2, d1 and d22) as neoadjuvant chemotherapy, followed by esophagectomy.Postoperation: 2 cycles of adjuvant chemotherapy with same regimen was given in 4-6 weeks after the resection.The primary endpoint was pathological response rate. The second endpoints included R0 resection rate,down-staging rate, 3 years overall survival (OS) and disease-free survival (DFS). Results: From 01/2011 to 10/2012, 35 pts were enrolled. 31 male:4 females; IIA/IIB/IIIA/IIIB/IIIC in 3 (8.6%), 5 (14.3%),10 (28.6%), 8 (22.9%) and 9 (25.7%) pts. 30/35 pts went to surgery (85.7%). 30 had R0 resection (100%). Pathological complete response (pCR) was achieved in 4 pts (13.3%). Near pCR (microfoci of tumor cells on the primary tumor without lymph nodal metastases) in 2 pt (6.7%). Down-staging was observed in 19 of 30 patiens (63.3%). 5 pts did not going to surgery: 2 for progressive disease, 3 for refused. 24/30 pts (80.0%) received adjuvant chemotherapy, 7 pts (23.3%) received adjuvant chemoradiotherapy. Grade 3/4 toxicities in 35 evaluable pts during chemotherapy were as follow: neutropenia (11.4%), anemia (8.6%), thrombocytopenia (5.7%), nausea/vomiting (14.3%), neutropenia fever (8.6%), asthenia (20.0%). Surgical complications: 1 anastomotic leaks (3.3%). No treatment-related death. At a median follow up of 12 months (8~20mos), 29 pts were all disease-free survival. Conclusions: In pts with locally advanced esophageal SCC, weekly nab-paclitaxel and cisplatin as neoadjuvant chemotherapy achieved a high pathological response rate and R0 resection rate. The toxicity was well tolerated. Evaluation of nab-paclitaxel and cisplatin in randomized trials was warranted. Clinical trial information: NCT01258192.

Abstract Background Currently, there is no reliable blood-based marker to track tumor recurrence in endometrial cancer (EC) patients. Liquid biopsies, specifically, circulating tumor DNA (ctDNA) analysis emerged as a way to monitor tumor metastasis. The objective of this study was to examine the feasibility of ctDNA in recurrence surveillance and prognostic evaluation of high-risk EC. Methods Tumor tissues from nine high-risk EC patients were collected during primary surgery and tumor DNA was subjected to next generation sequencing to obtain the initial mutation spectrum using a 78 cancer-associated gene panel. Baseline and serial post-operative plasma samples were collected and droplet digital PCR (ddPCR) assays for patient-specific mutations were developed to track the mutations in the ctDNA in serial plasma samples. Log-rank test was used to assess the association between detection of ctDNA before or after surgery and disease-free survival. Results Somatic mutations were identified in all of the cases. The most frequent mutated genes were PTEN, FAT4, ARID1A, TP53, ZFHX3, ATM, and FBXW7. For each patient, personalized ddPCR assays were designed for one-to-three high-frequent mutations. DdPCR analysis and tumor panel sequencing had a high level of agreement in the assessment of the mutant allele fractions in baseline tumor tissue DNA. CtDNA was detected in 67% (6 of 9) of baseline plasma samples, which was not predictive of disease-free survival (DFS). CtDNA was detected in serial post-operative plasma samples (ctDNA tracking) of 44% (4 of 9) of the patients, which predicted tumor relapse. The DFS was a median of 9 months (ctDNA detected) versus median DFS undefined (ctDNA not detected), with a hazard ratio of 17.43 (95% CI, 1.616–188.3). The sensitivity of post-operative ctDNA detection in estimating tumor relapse was 100% and specificity was 83.3%, which was superior to CA125 or HE4. Conclusions Personalized ctDNA detection was effective and stable for high-risk EC. CtDNA tracking in post-operative plasma is valuable for predicting tumor recurrence.

Background There is no standard adjuvant chemotherapy to prevent recurrent cholangiocarcinoma (CCA), a rare cancer with poor prognosis. We assessed the efficacy and safety of GEMOX on intrahepatic and hilar CCA with high-risk factors after curative surgery. Patients and Methods Twenty two patients (mean age: 57 years old) with CCA received 6 cycles of GEMOX: gemcitabine 1,000 mg/m2 on day 1 and oxaliplatin 85 mg/m2 on day 2, q3w after a curative surgery. Results All patients completed 6 cycles of GEMOX. EGFR membranous expression was present in 20 CCA. The 5-year survival rate was 56% (CI 95%: 25.7–85.4); 2-year disease free survival rate was 28% (CI 95%: 3.4–52.6). Median time to progression was 15 months. The rate of recurrence after surgery and chemotherapy was 63% (14/22). Two patients died of disease progression. Twelve patients received cetuximab/GEMOX at the time of relapse. Six died after 12 months (9–48 months), three are still alive suggesting a clinical applicability of EGFR inhibitors in CCA. Conclusion Adjuvant chemotherapy with GEMOX alone seems ineffective in intrahepatic and hilar CCA with a high risk of relapse. Additional studies including targeted therapies to circumvent such poor chemosensitivity are needed.

391 Background: The standard of care (SOC) for patients (pts) with MIUC is radical surgery ± cisplatin-based neoadjuvant chemotherapy (chemo), but many pts are cisplatin-ineligible. There is no conclusive evidence supporting adjuvant chemo in pts who did not receive neoadjuvant chemo and in those with residual disease after neoadjuvant cisplatin. This phase 3 trial of adjuvant nivolumab (NIVO) vs placebo (PBO) in pts with MIUC after radical surgery ± neoadjuvant cisplatin (CheckMate 274) aims to address an unmet need in these pts. We report the initial results. Methods: This is a phase 3, randomized, double-blind, multicenter trial of NIVO vs PBO in pts with high-risk MIUC (bladder, ureter, or renal pelvis) after radical surgery. Pts were randomized 1:1 to NIVO 240 mg Q2W or PBO for ≤ 1 year of adjuvant treatment. Pts had radical surgery within 120 days ± neoadjuvant cisplatin or were ineligible/declined cisplatin-based chemo, evidence of UC at high risk of recurrence per pathologic staging, were disease-free by imaging, and ECOG PS ≤ 1. Primary endpoints: disease-free survival (DFS) in all randomized pts (ITT population) and in pts with tumor PD-L1 expression ≥ 1%. DFS was stratified by nodal status, prior neoadjuvant cisplatin, and PD-L1 status. Non–urothelial tract recurrence-free survival (NUTRFS) in ITT pts and in pts with PD-L ≥ 1% is a secondary endpoint. Safety is an exploratory endpoint. Results: In total, 353 pts were randomized to NIVO (PD-L1 ≥ 1%, n = 140) and 356 pts to PBO (PD-L1 ≥ 1%, n = 142). The primary endpoint of DFS was met in ITT pts (median follow-up, 20.9 mo for NIVO; 19.5 mo for PBO) and in pts with PD-L1 ≥ 1%. DFS and NUTRFS were improved with NIVO vs PBO in both populations (Table). DFS improvement with NIVO was generally consistent across subgroups. Grade 3–4 treatment-related adverse events (TRAEs) occurred in 17.9% and 7.2% of pts in the NIVO and PBO arms, respectively. Conclusions: NIVO demonstrated a statistically significant and clinically meaningful improvement in DFS vs PBO for MIUC after radical surgery, both in ITT pts and pts with PD-L1 ≥ 1%. AEs were manageable and consistent with previous reports. These results support adjuvant NIVO as a new SOC for pts with MIUC with high risk for recurrence despite neoadjuvant chemo or those ineligible for and/or declining cisplatin-based chemo.

PURPOSE Radiotherapy (RT) plus long-term androgen suppression (AS) are a standard treatment option for patients with high-risk localized prostate cancer. We hypothesized that docetaxel chemotherapy (CT) could improve overall survival (OS) and clinical outcomes among patients with high-risk prostate cancer. PATIENTS AND METHODS The multicenter randomized NRG Oncology RTOG 0521 study enrolled patients with high-risk nonmetastatic disease between 2005 and 2009. Patients were randomly assigned to receive standard long-term AS plus RT with or without adjuvant CT. RESULTS A total of 612 patients were enrolled; 563 were evaluable. Median prostate-specific antigen was 15.1 ng/mL; 53% had a Gleason score 9 to 10 cancer; 27% had cT3 to cT4 disease. Median follow-up was 5.7 years. Treatment was well tolerated in both arms. Four-year OS rate was 89% (95% CI, 84% to 92%) for AS + RT and 93% (95% CI, 90% to 96%) for AS + RT + CT (hazard ratio [HR], 0.69; 90% CI, 0.49 to 0.97; one-sided P = .034). There were 59 deaths in the AS + RT arm and 43 in the AS + RT + CT arm, with fewer deaths resulting from prostate cancer in the AS + RT + CT arm versus AS + RT (23 v 16 deaths, respectively). Six-year rate of distant metastasis was 14% for AS + RT and 9.1% for AS + RT + CT, (HR, 0.60; 95% CI, 0.37 to 0.99; two-sided P = .044). Six-year disease-free survival rate was 55% for AS + RT and 65% for AS + RT + CT (HR, 0.76; 95% CI, 0.58 to 0.99; two-sided P = .043). CONCLUSION For patients with high-risk nonmetastatic prostate cancer, CT with docetaxel improved OS from 89% to 93% at 4 years, with improved disease-free survival and reduction in the rate of distant metastasis. The trial suggests that docetaxel CT may be an option to be discussed with selected men with high-risk prostate cancer.
