    Abstract: To report the efficacy and safety of postoperative adjuvant hepatic arterial infusion chemotherapy (HAIC) with 5-fluorouracil and oxaliplatin (FOLFOX) in hepatocellular carcinoma (HCC) patients with microvascular invasion (MVI). PATIENTS AND METHODS In this randomized, open-label, multicenter trial, histologically confirmed HCC patients with MVI were randomly assigned (1:1) to receive adjuvant FOLFOX-HAIC (treatment group) or routine follow-up (control group). The primary end point was disease-free survival (DFS) by intention-to-treat (ITT) analysis while secondary end points were overall survival, recurrence rate, and safety. RESULTS Between June 2016 and August 2021, a total of 315 patients (ITT population) at five centers were randomly assigned to the treatment group (n = 157) or the control group (n = 158). In the ITT population, the median DFS was 20.3 months (95% CI, 10.4 to 30.3) in the treatment group versus 10.0 months (95% CI, 6.8 to 13.2) in the control group (hazard ratio, 0.59; 95% CI, 0.43 to 0.81; P = .001). The overall survival rates at 1 year, 2 years, and 3 years were 93.8% (95% CI, 89.8 to 98.1), 86.4% (95% CI, 80.0 to 93.2), and 80.4% (95% CI, 71.9 to 89.9) for the treatment group and 92.0% (95% CI, 87.6 to 96.7), 86.0% (95% CI, 79.9 to 92.6), and 74.9% (95% CI, 65.5 to 85.7) for the control group (hazard ratio, 0.64; 95% CI, 0.36 to 1.14; P = .130), respectively. The recurrence rates were 40.1% (63/157) in the treatment group and 55.7% (88/158) in the control group. Majority of the adverse events were grade 0-1 (83.8%), with no treatment-related death in both groups. CONCLUSION Postoperative adjuvant HAIC with FOLFOX significantly improved the DFS benefits with acceptable toxicities in HCC patients with MVI.

    Abstract: 4013 Background: To report the efficacy and safety of postoperative adjuvant hepatic arterial infusion chemotherapy (HAIC) with FOLFOX (5- fluorouracil, leucovorin, and oxaliplatin) in hepatocellular carcinoma (HCC) patients with microvascular invasion (MVI). Methods: In this randomized, open label, multicenter, phase 3 trial, histologically confirmed HCC patients with MVI were randomized (1:1) to receive either 1 to 2 cycles of adjuvant HAIC-FOLFOX (treatment group) or routine follow-up without any adjuvant treatment (control group). The primary endpoint was disease free survival (DFS), Secondary endpoints included overall survival (OS), recurrence rate and safety. Survival rates were calculated by the Kaplan-Meier plots. Adverse events (AE) were graded according to NCI-CTCAE version 5.0. Results: Between June, 2016 and August, 2021, a total of 315 patients in 5 centers were enrolled in to the study and eligible patients were randomly assigned to the treatment group (n = 157) or control group (n = 158) and were included in the intention-to-treat (ITT) population. Among these 14 patients from treatment group and 15 patients from control group were excluded from the per-protocol (PP) population. 148 patients in treatment group underwent at least 1 cycle of HAIC were included in safety analyses. The median DFS of treatment group and control group were 27.0 months (95% CI, 17.0-37.0) and 11.3 months (95% CI, 7.9-14.7), respectively in ITT population, while which was 20.4 months (95% CI, 9.5-31.3) and 9.7 months (95% CI, 6.9-12.4), respectively in PP population. The DFS were significantly better in the treatment group than in the control group in both ITT population and PP population (p = 0.001 and 〈 0.001, respectively). The DFS rates at 1, 2, and 3-years were 64.3%, 50.4%, and 44.3% in treatment group and 47.3%, 33.3%, and 24.2% in control group, respectively in ITT population, while which were 64.0%, 48.2%, and 42.2% in treatment group and 43.3%, 27.1%, and 18.4% in control group, respectively in PP population. The OS rates at 1, 2, and 3-year for the treatment group were 94.7%, 87.6%, and 80.5%, and were 91.9%, 85.9%, and 77.0% for the control group, respectively in ITT population, while which were 94.9%, 86.7%, and 80.9% in treatment group and 91.8%, 84.9%, and 75.3% in control group, respectively in PP population. Furthermore, in ITT population, there were 63 (40.1%) patients in the treatment group and 88 (55.7%) patients in the control group had recurrence. Majority of the AEs observed were grade 0-1 (n = 124 (83.8%)) and no treatment related death was observed during the study period. Conclusions: Postoperative adjuvant HAIC with FOLFOX significantly improved the survival benefits with acceptable toxicities in HCC patients with MVI. Clinical trial information: NCT03192618.

    Abstract: 6006 Background: In intensity-modulated radiotherapy (IMRT) era, concurrent chemoradiotherapy (CCRT) with either every three week (ETW) or once a week (OAW) cisplatin is accepted practice for locoregionally advanced nasopharyngeal carcinoma (LANPC). However, ETW and OAW were never prospectively compared in phase 3 clinical trials. This study is to assess the efficacy and toxicity profiles of CCRT with ETW versus OAW schedule of cisplatin. Methods: We conducted an open-label phase 3 multicentre randomised controlled trial in an endemic area. Patients with stage II-IVB NPC were randomly assigned to receive either cisplatin 100 mg/m² every 3 weeks for 2 cycles or cisplatin 40 mg/m² weekly up to 6 cycles concurrently with IMRT. IMRT in both groups was given as 2.19-2.34 Gy per fraction with five daily fractions per week for 6-7 weeks to a total dose of 68-70 Gy to the primary tumor and 62-68 Gy to the involved neck area. The primary endpoint was failure-free survival. Intention-to-treat population was adopted for efficacy analyses. Results: Of the 526 eligible patients, 267 were assigned to OAW arm, and 259 to ETW arm. Two arms were well-balanced in all prognostic factors. No difference was observed in overall tumor response between OAW and ETW (99.6% vs 98.9%, P = 0.624). After a median follow-up of 17.5 months (range 1.6-64.1), estimated 2 year failure-free survival rate was 92% (95% CI 87.7-96.3) in OAW and 88.3% (95% CI 83.2-93.4) in ETW (hazard ratio 1.056, 95% CI 0.58-1.92). The grade 3 or 4 toxicities were similar between two arms, but leucopenia and thrombocytopenia were significantly higher in OAW compared with ETW (24.8% vs 15.9%, P = 0.015 and 5.2% vs 1.1%, P = 0.01, respectively). Stomatitis (35.2% vs 32.6%, P = 0.576), leucopenia and nausea/vomiting (11.2% vs 12.5%, P = 0.684) were the most commonly observed grade 3 or 4 toxicities during both OAW and ETW arms. Conclusions: Weekly regimen of cisplatin as CCRT shows similar treatment efficacy but increased toxic effect of leucopenia and thrombocytopenia compared with 3-weekly schedule in LANPC. Longer follow-up is needed to fully assess prognosis and late toxicities. Clinical trial information: ChiCTR-TRC-12001979.

    Abstract: 4008 Background: The efficacy of operation, as the only radical option for resectable BCLC stage A/B hepatocellular carcinoma (HCC) patients beyond Milan criteria, is still unsatisfactory. This study aimed to investigate to efficacy and safety of preoperative neoadjuvant transarterial infusion chemotherapy (TAI) with FOLFOX regimen for these patients. Methods: In this multi-center, prospective, phase 3, randomized, open-labeled, controlled clinical trial, resectable BCLC stage A/B HCC patients beyond Milan criteria were randomly assigned (1:1) before hepatectomy to receive either neoadjuvant TAI (NT group) or operation directly without any neoadjuvant treatment (OP group). The primary endpoint was overall survival (OS), the secondary endpoints are progression-free survival (PFS), recurrence free survival (RFS), and safety. Results: Between March, 2016 and July, 2020, 208 patients enrolled from five Chinese hospitals were randomly assigned to NT group (n=104) or OP group (n=104)， with 99 patients in NT group and 100 patients in OP group included in the efficacy and safety analysis. Clinicopathological characteristics were balanced between the two groups. The 1-, 2-, and 3-year OS rates for NT group were 92.9%, 78.6%, and 63.5%, and were 79.5%, 62.0%, and 46.3% for OP group, respectively. The 6-, 12-, and 18-month PFS rates for NT group were 77.6%, 50.4%, and 47.4%, and were 52.7%, 42.8%, and 34.8% for OP group, respectively. The OS and PFS were significantly better in NT group than in OP group (p=0.016 and 0.017, respectively). The 6-, 12-, and 18-month RFS rates for NT group were 63.8%, 47.3%, and 47.3%, and were 52.7%, 42.8%, and 34.8% for OP group, respectively. The RFS between the two group had no difference (p=0.385). No patients in NT group experienced grade 3 or more severe TAI related adverse events. The operation related adverse events were similar between two groups (p=0.300). Conclusions: Neoadjuvant TAI before hepatectomy may bring survival benefits for resectable BCLC stage A/B HCC patients beyond Milan criteria. Trial number: NCT03851913. Clinical trial information: NCT03851913.

    Abstract: e14057 Background: This study aimed to investigate the prognostic value of transcriptome and clinical data of Hepatocellular carcinoma (HCC) patients for overall survival (OS) by deep learning method. Methods: A total of 371 HCC patients with 20530 level three RNA-sequencing data were from The Cancer Genome Atlas (TCGA). Cox-nnet model, a deep learning model through an artificial neural network extension of the Cox regression model, was used for OS prediction. The patients were randomly split into train-set and test-set (7:3). In train-set, the significant genes associated with OS under univariate Cox regression were considered for modeling. Clinical parameters, including age, gender, pathologic stage, child pugh classification, creatinine level etc. were also considered. The Cox-nnet model was developed by cross-validation. Its discrimination was determined by the concordance index (CI) in the independent test-set and compared with multivariable Cox regression. The clustering method Uniform Manifold Approximation and Projection (UMAP) was used for revealing biological information from the hidden layer in the model. Results: In the train-set (n = 259), 1505 genes and two clinical variables (child pugh score and creatinine level) were significantly associated with OS (adjusted P-value 〈 0.05). To avoid overfitting, only 40 most significant genes were included in the Cox-nnet model. In the test-set (n = 112), the CI of Cox-nnet (0.76, se = 0.04) is better than the CI of multivariable Cox regression (0.71, se = 0.05). The difference between good or poor survival subgroups classified by Cox-nnet was remarkably significant ( P-value = 1e-4, median OS: 80.7 vs. 25.1 months). In the Cox-nnet model with all significant variables, the weights in the hidden layer were clustered by UMAP into 3 positive clusters and 2 negative clusters, which are enriched in GO/KEGG. The “cell cycle” and “complement and coagulation cascades” are the most important signal pathways in positive and negative clusters, respectively. Conclusions: Combining transcriptomic and clinical data, and with deep learning algorithm, we built and validated a robust model for survival prediction in HCC patients. Our study would be useful to explore the clinical implications in survival prediction and corresponding genetic mechanisms.

The primary endpoint was overall survival (OS), the secondary endpoints are progression-free survival (PFS) and safety. Results: Between March 2016 and August 2022, a total of 487 patients were screened from seven Chinese hospitals, and 392 patients were randomly assigned to receive neoadjuvant FOLFOX-HAIC before hepatectomy (treatment group, n = 195), or operation directly without any neoadjuvant treatment (control group, n = 197) and were included in the ITT population. Among them, 14 patients from the treatment group and 13 patients from the control group were excluded from the PP population. In the ITT population, the OS rates at 1-, 2-, and 3-year were 97.7%, 86.3%, and 77.1%, respectively, for the treatment group and were 90.0%, 80.9%, and 70.6%, respectively, for the control group. The median PFS of the treatment and control groups was 17.4 months (95% CI, 9.0-25.8) and 9.8 months (8.2-11.4), respectively, in the ITT population. The OS and PFS were significantly better in treatment group than in control group (p = 0.032 and 〈 0.001, respectively) in ITT population. In the PP population, the OS rates at 1-, 2-, and 3-year were 98.7%, 91.1%, and 79.7%, respectively, for the treatment group and were 89.2%, 79.3%, and 67.7%, respectively, for the control group. The median PFS of the treatment and control groups was 22.7 months (95% CI, 10.9-34.5) and 10.2 months (8.4-12.1), respectively, in the PP population. The OS and PFS were significantly better in treatment group than in control group (p = 0.001 and 〈 0.001, respectively) in PP population. In treatment group of ITT population, the complete regression (CR) rate, object response rate (ORR), disease control rate (DCR) was 11.3%, 61.5%, and 97.4%, respectively. Safety analysis showed HAIC was quite safe, 191 (97.9%) patients had mild HAIC related adverse events (HRAEs) (grade 0-2). The operation related adverse events (ORAEs) were similar between two groups (p = 0.265). Conclusions: Neoadjuvant HAIC with FOLFOX regimen before hepatectomy may bring survival benefits for resectable BCLC stage A/B HCC patients beyond Milan criteria.

    Abstract: 1019 Background: Preclinical studies show cross talk between RET and estrogen receptor, with at least additive treatment (Tx) effect of Len, a RET inhibitor, with Let. Our previous work concluded a recommended phase 2 dose (RP2D) of Len 14mg daily and Let 2.5mg daily (Lim, ASCO 2019). We present efficacy data from dose escalation and expansion cohorts. Methods: Safety, tolerability and efficacy data of MBC patients in both dose escalation (Len dose level 1 [DL]:20mg, DL -1:16mg and DL -2:14mg) and expansion (Len 14mg) cohort of this phase Ib/II study of combination Len+Let study was analysed. Patients were treated with single-agent Len for 2 weeks, followed by Len+Let until disease progression (PD). Serial tumor biopsies at baseline, after Len alone, 4 weeks post Len+Let, and upon PD, were sequenced for 440 genes with the ACTOnco+ platform. Results: A total of 33 pts (DL1 6pts, DL-1 6pts, DL-2 + expansion 21pts) with median 5 lines of prior Tx (range 0-11) were enrolled; 87.9%, 75.8%, and 75.8% had prior endocrine therapy (ET), ET+CDK4/6 inhibitor (i), and chemotherapy (CT) respectively. Objective response rate (ORR), disease control rate (DCR) ≥6 months (m), median duration of response (DOR), and percentage progression-free (PPF) at 12m were 33.3%, 45.5%, 11.5m (range 6.3-22.4), and 27.2% respectively. Among patients who previously progressed on CDK4/6i (n = 25), ORR, DCR ≥6m, median DOR, and PPF at 12m were 24.0%, 40.0%, 13.7m (range 6.3-18.2), and 12.0% respectively. Of note, 3/25 (12%) patients had durable response to Len+Let lasting ≥12m, despite having only modest PFS on ET+CDK4/6i (3, 7, and 12 months respectively). Most frequent all-grade toxicities (tox) were HTN (n = 15, G3:15), hypothyroidism (n = 20, G3:0) and fatigue (n = 13, G3:2), with no G4/5 tox. No new toxicity signals were observed compared to dose escalation phase. Pre-treatment tumor molecular profiling showed responders to be more likely to harbor NEFH, USH2A and PTCH1 mutations, while non-responders were more likely to carry PIK3R1, APC and PALB2 mutations. Sequencing of serial biopsies showed downregulation of BRD4, PTCH1, KIT, NTRK1 and CREBBP after Len treatment. Conclusions: Len+Let showed significant anti-tumor activity with meaningful duration of response, even in pts who failed prior CT or ET+CDK4/6i. The results support further investigation in randomized studies. Tumor profiling identified mutations associated with response and insights on molecular effects of lenvatinib.

    Abstract: e16623 Background: The management of aHCC has evolved dramatically in recent years, with new agents like immunotherapy receiving regulatory approval. As we begin incorporating these drugs into routine clinical practice, data on real-world sequencing of therapies and clinical outcomes are needed. Methods: We utilised the DISCOVERYAI platform, a virtual machine containing de-identified patient electronic health records to review HCC patients treated at the National University Health System, Singapore from January 2015 to December 2019. We then identified those who received systemic therapy and correlated their clinical outcomes. Results: In total, 395 HCC patients were identified; 75 received surgery, 174 received loco-regional therapy and 102 referred for consideration of systemic therapy. Of those considered for systemic therapy, median age was 65 years (range 23-87); 88% male (n = 90); hepatitis B/hepatitis C/non-hepatitis, 41(40.2%)/ 10(9.8%)/ 51(50.0%). 75.5% (n = 77) of them received systemic therapy with a TKI and/or immunotherapy. 39% (n = 30) of these received second-line treatment. Child-Pugh score at start of treatment was A5/A6/B7/B8, 38(49.3%)/ 32(41.6%)/ 5(6.5%)/ 2(2.6%) respectively. In the first-line, 66% (n = 51) received TKI and 34% (n = 26) received immunotherapy. Amongst those treated with first-line TKI, 45% (n = 23) received second-line therapy; 65% (n = 15) immunotherapy, 35% (n = 8) another TKI. Of those treated with first-line immunotherapy, 27% (n = 7) received second-line TKI. At a median follow-up of 35 months, first-line median progression-free survival (mPFS) for TKI vs immunotherapy was 3.7 vs 3.1 months (HR 0.73; 95% CI, 0.40-1.33; p = 0.31). mPFS for second-line immunotherapy vs TKI was 4.0 vs 2.9 months (HR 0.43; 95% CI, 0.19-0.96; p = 0.04). When comparing sequencing of therapies, the combined first and second mPFS for TKI-immunotherapy/TKI-TKI/immunotherapy-TKI is 9.5/7.6/7.6 months respectively (log-rank test, p = 0.71). Those patients that received both immunotherapy and TKI had significantly higher overall survival (OS) compared to those receiving only immunotherapy or only TKI or none (mOS NR vs 10.1 vs 13.2 vs 4.7 months; p 〈 0.001). Conclusions: TKI remains an important pillar of treatment in aHCC in the era of immunotherapy. While immunotherapy provides long durable responses and benefit in a minority of patients, the majority appear to benefit from TKI. Biomarker studies are needed to discern treatment algorithms for aHCC.

    Abstract: 552 Background: Extensive efforts by The Cancer Genome Atlas (TCGA) Network had provided much of our current understanding of the molecular profile of various solid tumors including breast tumors; however, Asian patients were underrepresented in this cohort. In this study, we aimed to elucidate the comprehensive genetic alteration profile of early-stage breast tumors among Chinese patients. Methods: Surgical tissue samples from 589 Chinese women with stage I-III breast cancer with various histology and molecular subtype consecutively diagnosed at Guangdong Provincial People’s Hospital were sequenced using a panel targeting 520 cancer-related genes spanning 1.64Mb of the human genome. Clinical and genomic data from our cohort was compared with publicly-available data from 1,046 stage I-III breast cancer patients from the TCGA dataset. Results: Based on the analysis of the genetic alteration profile from our cohort, at least one genetic alteration was observed from 98% of the tumor samples, with TP53 (47%), PIK3CA (45%), ERBB2 (30%), and CDK12 (18%) as the most commonly altered genes. The most common genetic alteration types were copy number amplification (43.6%) and missense mutations (36.8%). As compared with the TCGA dataset, our cohort is mostly composed of women 50 years and younger (59.1% vs. 30.4%, P 〈 0.001), with significantly fewer patients with lobular carcinoma histology (2.4% vs. 19.0%, P 〈 0.001), and significantly more patients with pathologic stage I tumors (23.3% vs. 17.3%, P= 0.012). Consistently, genetic alterations detected from our cohort affected genes involved in PI3K (63% vs. 56%, P= 0.009) and cell cycle (23% vs. 35%, P 〈 0.001) pathways, with statistically different genetic alteration rates as compared with the TCGA dataset. Comparison of genetic alteration profile between the two cohorts revealed that our cohort had more frequent genetic alterations in genes including PIK3CA ( P 〈 0.001), TP53, particularly in hotspot mutations Q192* ( P 〈 0.001) and A307V/del ( P= 0.02), and ERBB2 amplification ( P 〈 0.001). Conclusions: Our study contributes to the understanding of the key pathways and specific genetic alterations harbored by Chinese patients with early-stage breast cancer that could potentially be developed as markers of treatment response to targeted therapeutics.

    Abstract: 4590 Background: Nivolumab (N) and Y90-radioembolization (RE) are both therapeutic options in advanced hepatocellular carcinoma (aHCC). Increasing evidence suggests that radiotherapy synergizes with immune checkpoint inhibitors to augment anti-tumour effects. Methods: Eligible Child-Pugh A aHCC patients (pts) were treated with Y90-RE followed by N 240mg, 21 days after Y90-RE and every 2 weeks thereafter. Pre- and on-treatment tumor biopsies together with circulating biomarkers were obtained. Primary end-point was overall response rate (ORR) (per RECIST v 1.1). Overall response was defined as the composite overall response observed for the lesions within Y90-RE field and outside Y90-RE field. Key secondary end points included disease control rate (DCR), progression free survival (PFS), overall survival (OS), and safety. 36 evaluable pts were needed to assess whether the addition of N improved the ORR of Y90-RE from 21% to 41% as determined by Simon two-stage optimal design with 80% power and one sided significance level of 0.05. Results: Forty pts were enrolled of which 36 were evaluable. At baseline: 63.9% were HepB in aetiology; 63.9% BCLC stage C; 47.2% had AFP 〉 400ng/mL; number of liver lesions – median 5 (range 1- 20); size of largest liver lesion – median 80mm (range 14-177mm); 27.8% had prior TACE; and 13.9% had prior systemic therapy. ORR was 31% (95% CI 16.4 - 48.1%). Eight out of 11 responders had not progressed at study cut-off. DCR was 58.3%. 81% of target lesions within Y90-RE field regressed. With a median follow up of 16.4 months, median PFS and OS were 4.6 months (95% CI 2.3m - 8.4m) and 15.1 months (95% CI 7.8m - NE) respectively. Six- and 12-month PFS rates were 44.2% (95% CI 27.3% - 59.9%) and 26.1% (95% CI 11.2% - 43.8%) respectively. Overall, N+ Y90-RE was well tolerated and safe; only 11% had grade 3/4 treatment related adverse events (AEs). Responders demonstrated significant alterations of LIF, MIG and Eotaxin3 levels in the pre-treatment cytokine analyses. Conclusions: Combination N+Y90-RE resulted in an encouraging ORR of 31% (95% CI 16.4 - 48.1%) in aHCC. 81% of target lesions within Y90-RE field regressed suggesting synergy in combining Y90-RE with nivolumab. This combination is safe and tolerable with low G3/4 treatment related AEs of 11%. Further biomarker analyses will be presented at the meeting. Clinical trial information: NCT03033446 .
