141 Background: Anthracyclines (A), given in sequence or combination with other agents, have been the mainstay of adjuvant chemotherapy (CTX) for ESBC for more than two decades. Recent molecular studies have questioned the value of A for lower risk disease. A single prospective trial presented in 2005 and published in 2006 (Jones et al) compared docetaxel and cyclophosphamide (TC) to doxorubicin and cyclophosphamide and reported improved disease free survival (2006) and overall survival (2009) with TC. We sought to understand the impact of this study on the type of CTX regimens used to treat ESBC. Methods: Using the UCSF Cancer Registry database and including patients who received at least one cycle of CTX at UCSF, we recorded use of A or non-anthracycline (NA) based CTX regimens in women with ESBC and correlated type of CTX with tumor stage, receptor status, and age. Based on the publication date of TC we looked at the use of A versus NA based CTX during two time periods, 2000-2005 and 2006-2010. Results: 1,116 patients met criteria for inclusion; 17 were excluded due to inadequate information. Patient characteristics were: median age 49 (range 21-78), stage I (24%), stage II (56%), and stage III (20%), 50% hormone receptor (HR) +, 25% HER2 +, 17% HR-/HER2-. From 2000-2010, 80% received A CTX. Overall use of A decreased from 95% to 65%, while use of NA based CTX increased from 5% to 35%. The table compares use of NA CTX during the two time periods by clinical variables. Conclusions: Use of NA CTX increased significantly over the 2nd half of the last decade in all cases except those patients with stage III disease. The timing of this marked change correlates with publication of TC, and emphasizes the impact of positive phase III trials on treatment practice. This study was supported by the UCSF Cancer Registry.

Abstract Introduction The current phase III EORTC 1420 Best-of trial (NCT02984410) compares the swallowing function after transoral surgery versus intensity modulated radiotherapy (RT) in patients with early-stage carcinoma of the oropharynx, supraglottis and hypopharynx. We report the analysis of the Benchmark Case (BC) procedures before patient recruitment with special attention to dysphagia/aspiration related structures (DARS). Materials and methods Submitted RT volumes and plans from participating centers were analyzed and compared against the gold-standard expert delineations and dose distributions. Descriptive analysis of protocol deviations was conducted. Mean Sorensen-Dice similarity index (mDSI) and Hausdorff distance (mHD) were applied to evaluate the inter-observer variability (IOV). Results 65% (23/35) of the institutions needed more than one submission to achieve Quality assurance (RTQA) clearance. OAR volume delineations were the cause for rejection in 53% (40/76) of cases. IOV could be improved in 5 out of 12 OARs by more than 10 mm after resubmission (mHD). Despite this, final IOV for critical OARs in delineation remained significant among DARS by choosing an aleatory threshold of 0.7 (mDSI) and 15 mm (mHD). Conclusions This is to our knowledge the largest BC analysis among Head and neck RTQA programs performed in the framework of a prospective trial. Benchmarking identified non-common OARs and target delineations errors as the main source of deviations and IOV could be reduced in a significant number of cases after this process. Due to the substantial resources involved with benchmarking, future benchmark analyses should assess fully the impact on patients’ clinical outcome.

BackgroundWe have completed a prospective, randomized, multi-center, double-blind, placebo-controlled phase IIb trial of the tumor lysate, particle loaded, dendritic cell (TLPLDC) vaccine given to prevent recurrences in patients with resected stage III/IV melanoma. During the trial, granulocyte colony stimulating factor (G-CSF) was administered to some patients to mobilize dendritic cells (DCs) precursors prior to harvest, allowing for similar DC yield with reduced blood draws. This study examines the impact of DC collection methods on vaccine effectiveness.MethodsTLPLDC is produced by loading tumor lysate into pre-prepared yeast cell wall particles (YCWPs) and exposing them to autologous DCs. DC precursors were isolated either by collection of 50–70 mL of blood following pre-administration of 300µg of G-CSF 24–48 hrs prior, or collection of 120 mL of peripheral blood without G-CSF pretreatment based on patient and provider preference. Patients were randomized 2:1 to receive TLPLDC or placebo (DCs exposed to empty YCWPs). 1–1.5 × 106 cells/dose were injected intradermally at 0, 1, 2, 6, 12, and 18 months. Differences in disease free survival (DFS) and overall survival (OS) were analyzed by log rank.ResultsOf 144 patients randomized, 103 received TLPLDC and 41 received placebo. Within the TLPLDC group, 57 received pretreatment with G-CSF (TLPLDC+G-CSF) and 46 did not (TLPLDC–G-CSF). There were no significant clinicopathologic or treatment differences between the three treatment arms. 36-month DFS was significantly better in TLPLDC–G-CSF vs. TLPLDC+G-CSF or placebo (51.8% vs. 23.4% and 27.1% respectively, p=0.027) (figure 1). TLPLDC–G-CSF had correspondingly improved OS (92.9% vs. 62.8% and 72.3% respectively, p=0.022) (figure 2). Subgroup analysis revealed TLPLDC–G-CSF had increased DFS over TLPLDC+G-CSF or placebo in Stage IV (68.6% vs. 18.8% and 0.0% respectively, p=0.058). Similarly, the DFS survival benefit of TLPLDC–G-CSF was enhanced in patients who received prior immunotherapy (IO) (61.9% vs. 11.5% and 35.7% respectively, p=0.007) or checkpoint inhibitors (CPI) (48.5% vs. 10.6% and 37.5% respectively, p=0.039).Abstract 310 Figure 1DFS at 36 monthsAbstract 310 Figure 2OS at 36 monthsConclusionsTLPLDC vaccine created without G-CSF pretreatment significantly improved 36-month DFS and OS compared to TLPLDC+G-CSF or placebo in stage III/IV (resected) melanoma patients. On further subgroup analysis, the increases in OS and DFS were more profound in patients who received additional immune therapies to include CPI. Ongoing evaluation will determine if G-CSF mobilization leads to collection of phenotypically different DCs. Based on these results, we are planning a phase III trial of TLPLDC–G-CSF + CPI vs. placebo + CPI in advanced melanoma post-resection.Trial RegistrationClinicalTrials. gov Identifier: NCT02301611Ethics ApprovalThis study was reviewed and approved by the IRB or Independent Ethics Committee (IEC) of each participating center prior to study initiation.

1083 Background: Anthracyclines (A), given in sequence or combination, have been the mainstay of adjuvant CTX for ESBC. Recent molecular studies have questioned the value of A for ESBC. Trials for ESBC, presented primarily in 2005, have demonstrated similar or improved efficacy with non-anthracycline (NA) CTX. We sought to understand changing use of A for ESBC from 2000-2010 as reported in the population-based 9-county Greater Bay Area Cancer Registry (GBACR). Methods: Using the GBACR database, we recorded use of A or NA based CTX regimens in women with ESBC and no prior CTX from 2000-2010, and correlated type of CTX with tumor stage, receptor status, and age. We evaluated the use of A vs. NA (80% taxane-based) CTX from 2000-2005 and 2006-2010. Results: 16,476 patients (pts) met criteria for inclusion; 2,032 (12%) were excluded (missing information, or CTX not given). Pt characteristics were: median age 52 (range 21-94), stage I (25%), II (56%), and III (19%), 69% HR+. From 2000-2010, 83% received A; overall use of A decreased (87% to 57%), and use of NA increased (13% to 43%). The Table compares use of NA CTX during the two time periods by clinical variables. With short follow-up there was no difference in survival based on use of A vs. NACTX. Conclusions: Use of NA CTX significantly increased during 2006-2010; this trend was independent of age or receptor status and was more pronounced in earlier stage disease. The timing of this change correlated with the presentation of two phase III trials, emphasizing the impact of early data from phase III trials on treatment practice, and confirming results from a large claims database (Giordano). Potential outcome differences will be evaluated in NSABP-B49 and with longer follow-up of this cohort. This study was supported by the UCSF Cancer Registry and CPIC. [Table: see text]

Background10%–15% of early-stage colon cancers harbour either deficient mismatch repair (dMMR), microsatellite instability high (MSI-H) or POLE exonuclease domain mutations, and are characterised by high tumour mutational burden and increased lymphocytic infiltrate. Metastatic dMMR colon cancers are highly sensitive to immune checkpoint inhibition, and recent data show POLE-mutant tumours are similarly responsive. We are conducting a phase III randomised trial to determine if the addition of the anti-PD-L1 antibody avelumab following adjuvant chemotherapy improves disease-free survival (DFS) in patients with stage III dMMR/MSI-H or POLE mutant colon cancer and is a cost-effective approach for the UK National Health Service (NHS).MethodsWe are recruiting patients with completely resected, stage III colon cancer confirmed to have dMMR/MSI-H, locally or POLE exonuclease domain mutation on central testing. Eligible patients are randomised in a 1:1 ratio to standard fluoropyrimidine-based chemotherapy (capecitabine, oxaliplatin for 12 weeks or capecitabine for 24 weeks) or chemotherapy, followed by avelumab (10 mg/kg, 2 weekly for 24 weeks). Stratification is by chemotherapy received and MMR/MSI-H status. The primary endpoint is DFS. Secondary endpoints include overall survival, toxicity, quality of life and health resource use. The 3-year DFS rate in the control arm is expected to be ~75%. Avelumab is expected to improve the 3-year DFS rate by 12% (ie, 87%). Target accrual is 402 patients, which provides 80% power to detect an HR of 0.48 for DFS at a two-sided alpha of 0.05. This national, multicentre phase III trial is sponsored by the Royal Marsden NHS Foundation Trust and it is anticipated that approximately 40 centres in the UK will participate. This study opened to recruitment in August 2018.Trial registration numberNCT03827044

Purpose Reduction of adjuvant treatment duration may decrease toxicities without loss of efficacy in stage III colon cancer. This could offer clear advantages to patients and health care providers. Methods In International Duration Evaluation of Adjuvant Chemotherapy (IDEA) France, as part of the IDEA international collaboration, patient with colon cancer patients were randomly assigned to 3 and 6 months of modified FOLFOX6 (mFOLFOX6: infusional fluorouracil, leucovorin, and oxaliplatin) or capecitabine plus oxaliplatin (CAPOX) by physician choice. The primary end point was disease-free survival (DFS), and analyses were descriptive. Results A total of 2,010 eligible patients received either 3 or 6 months of chemotherapy (modified intention-to-treat population); 2,000 (99%) had stage III colon cancer (N1: 75%, N2: 25%); 1,809 (90%) received mFOLFOX6, and 201 (10%) received CAPOX. The median age was 64 years, and the median follow-up time was 4.3 years. Overall, 94% (3 months) and 78% (6 months) of patients completed treatment (fluoropyrimidines ± oxaliplatin). Maximal grade 2 and 3 neuropathy rates were 28% and 8% in the 3-month arm and 41% and 25% in the 6-month arm ( P < .001). Final rates of residual neuropathy greater than grade 1 were 3% in the 3-month arm and 7% in the 6-month arm ( P < .001). There were 578 DFS events: 314 and 264 in the 3- and 6-month arms, respectively. The 3-year DFS rates were 72% and 76% in the 3- and 6-month arms, respectively (hazard ratio [HR], 1.24; 95% CI, 1.05 to 1.46; P = .0112). In the 3 and 6-month arms, respectively, for patients who received mFOLFOX6, the 3-year DFS rates were 72% and 76% (HR, 1.27; 95% CI, 1.07 to 1.51); for the T4 and/or N2 population, they were 58% and 66% (HR, 1.44; 95% CI, 1.14 to 1.82); and for the T1-3N1 population, they were 81% and 83% (HR, 1.15; 95% CI, 0.89 to 1.49). Conclusion IDEA France, in which 90% of patients received mFOLFOX6, shows superiority of 6 months of adjuvant chemotherapy compared with 3 months, especially in the T4 and/or N2 subgroups. These results should be considered alongside the international IDEA collaboration data.

Abstract Natural killer (NK) cell recognition and killing of target cells are enhanced when inhibitory killer immunoglobulin-like receptors (KIR) are unable to engage their cognate HLA class I ligands. The genes of the KIR locus are organized into either KIR B haplotypes, containing 1 or more activating KIR genes or KIR A haplotypes, which lack those genes. Analysis of unrelated donor (URD) hematopoietic cell transplants (HCT), given to acute myeloid leukemia (AML) patients between 1988 and 2009, showed that KIR B haplotype donors were associated with better outcomes, primarily from relapse protection. Most of these transplants involved marrow grafts, fully myeloablative (MAC) preparative regimens, and significant HLA mismatch. Because the practice of HCT continues to evolve, with increasing use of reduced intensity conditioning (RIC), peripheral blood stem cell grafts, and better HLA match, we evaluated the impact of URD KIR genotype on HCT outcome for AML in the modern era (2010-2016). This analysis combined data from a prospective trial testing URD selection based on KIR genotypes (n = 243) with that from a larger contemporaneous cohort of transplants (n = 2419). We found that KIR B haplotype donors conferred a significantly reduced risk of leukemia relapse and improved disease-free survival after RIC, but not MAC HCT. All genes defining KIR B haplotypes were associated with relapse protection, which was significant only in transplant recipients expressing the C1 epitope of HLA-C. In the context of current HCT practice using RIC, selection of KIR B donors could reduce relapse and improve overall outcome for AML patients receiving an allogeneic HCT.

Abstract Prior reports have indicated that defective mismatch repair (MMR) has a favorable impact on outcome in colorectal cancer patients treated with surgery, immunotherapy, or adjuvant chemotherapy. However, the impact of MMR status on response to neoadjuvant radiotherapy in rectal cancer is not well understood. Here we report that dMMR was associated with improved disease-free survival (DFS) (P = 0.034) in patients receiving neoadjuvant chemotherapy (NCT). Patients with dMMR tumors who received neoadjuvant chemoradiotherapy (NCRT) achieved significantly worse DFS (P = 0.026) than those treated with NCT. Conversely, NCRT improved DFS (P = 0.043) in patients with pMMR tumors, especially for stage III disease with improved DFS (P = 0.02). The presence of dMMR was associated with better prognosis in rectal cancer patients treated with NCT. NCT benefited patients with dMMR tumors; while NCRT benefited patients with stage III disease and pMMR tumors. Patients stratified by MMR status may provide a more tailored approach to rectal cancer neoadjuvant therapy.

PURPOSE We conducted the phase III double-blind European Organisation for Research and Treatment of Cancer (EORTC) 1325/KEYNOTE-054 trial to evaluate pembrolizumab versus placebo in patients with resected high-risk stage III melanoma. On the basis of 351 recurrence-free survival (RFS) events at a 1.25-year median follow-up, pembrolizumab prolonged RFS (hazard ratio [HR], 0.57; P < .0001) compared with placebo. This led to the approval of pembrolizumab adjuvant treatment by the European Medicines Agency and US Food and Drug Administration. Here, we report an updated RFS analysis at the 3.05-year median follow-up. PATIENTS AND METHODS A total of 1,019 patients with complete lymph node dissection of American Joint Committee on Cancer Staging Manual (seventh edition; AJCC-7), stage IIIA (at least one lymph node metastasis > 1 mm), IIIB, or IIIC (without in-transit metastasis) cutaneous melanoma were randomly assigned to receive pembrolizumab at a flat dose of 200 mg (n = 514) or placebo (n = 505) every 3 weeks for 1 year or until disease recurrence or unacceptable toxicity. The two coprimary end points were RFS in the overall population and in those with programmed death-ligand 1 (PD-L1)–positive tumors. RESULTS Pembrolizumab (190 RFS events) compared with placebo (283 RFS events) resulted in prolonged RFS in the overall population (3-year RFS rate, 63.7% v 44.1% for pembrolizumab v placebo, respectively; HR, 0.56; 95% CI, 0.47 to 0.68) and in the PD-L1–positive tumor subgroup (HR, 0.57; 99% CI, 0.43 to 0.74). The impact of pembrolizumab on RFS was similar in subgroups, in particular according to AJCC-7 and AJCC-8 staging, and BRAF mutation status (HR, 0.51 [99% CI, 0.36 to 0.73] v 0.66 [99% CI, 0.46 to 0.95] for V600E/K v wild type). CONCLUSION In resected high-risk stage III melanoma, pembrolizumab adjuvant therapy provided a sustained and clinically meaningful improvement in RFS at 3-year median follow-up. This improvement was consistent across subgroups.

Introduction: Lymph node status has become part of the new staging system for cervical cancer (CC). It has been shown that patients staged as IIIC1 had heterogeneous prognoses and, in some cases, experienced better outcomes than patients with lower stages. We evaluated the impact of the number of metastatic pelvic lymph nodes (MPLNs) among patients with stage IIIC1 cervical cancer. Methods: Survival analyses were conducted in order to identify the best cut-off prognostic value relative to the number of MPLNs. Disease free survival (DFS) was considered the main outcome. Results: 541 patients were included in the study. Eighty-nine patients were of stage IIIC1. The best prognostic cut-off value of the number of MPLNs was 2. Patients with >2 MPLNs (n > 2 group) had worse DFS compared with those having <2 (N1-2 group) (5 yr DFS: 54.7% vs. 78.1%, p value = 0.006). Multivariate analyses demonstrated that the extent of MPLNs had little impact on DFS and that replacement of IIIC1 staging with N1-2 and n > 2 grouping provided a better, statistically significant model (p value = 0.006). Discussion: Using a cut-off value of 2, the number of MPLNs could better predict prognostic outcomes within stage IIIC1 cervical cancer and have potential implications for therapeutic decision-making in the treatment of patients with stage IIIC1 CC.

Abstract Adjuvant chemotherapy is the current standard treatment for stage III colorectal cancer after curative resection. However, the prognosis of stage III colorectal cancer is still poor even after curative resection and adjuvant chemotherapy. Several observational studies suggested that the anti-tumor effect of aspirin. Therefore, we planned a randomized double-blind placebo-controlled phase III trial, which commenced in Japan in March 2018, to confirm the superiority of aspirin over placebo added to adjuvant chemotherapy in terms of disease-free survival (DFS) for stage III colorectal cancer patients after curative resection. A total of 880 patients will be accrued from 20 Japanese institutions within 3 years. The primary endpoint is DFS and the secondary endpoints are overall survival, relapse-free survival, relative dose intensity, adverse events, and serious adverse events. This trial has been registered at Japan Registry of Clinical Trials as jRCTs031180009 (https://jrct.niph.go.jp/detail/589).
