e20574 Background: From the early 2000s, many advances in non-small cell lung cancer (NSCLC) have been made with the emergence of targeted therapies. However, because of safety concerns and a lower prevalence of relevant therapeutic targets, patients with squamous NSCLC have been excluded from many of these breakthroughs. Endostar is a novel inhibitor of tumor angiogenesis that acts specifically on neovascular endothelial cells. This study is to explore the clinical efficacy and safety of endostar in advanced squamous NSCLC patients. Methods: We performed a retrospective analysis of 259 newly diagnosed advanced squamous NSCLC patients who had received platinum-based doublet chemotherapy (PBDC) between September 2009 and March 2016. Of these patients, 116 received Endostar combined with PBDC, and 143 received PBDC only. Clinical tumor responses, progression-free survival (PFS), overall survival (OS), and toxicity profiles were recorded and analyzed. Results: After a median follow-up of 13.5 months, a improvement in PFS was observed in the Endostar group, the median PFS was7.7 months compared with 5.4 months in the control group (HR, 0.745; P= 0.034). The median OS was 19.0 months in the Endostar group versus 14.3 months in the control group, but the difference was not significant (HR, 0.780; P= 0.094). Multivariate analysis demonstrated that in patients with advanced squamous NSCLC, anti-angiogenesis therapy with Endostar, radiotherapy of primary tumor and Ⅲb stage were significant and independent predictors of improved PFS ( P< 0.05). For both arms, hematologic and gastrointestinal toxicities were the most common adverse events. Patients treated with Endostar had slightly higher rates of cardiac disorder and thromboembolic event, as compared with the control patients, but there were no statistically significant differences in toxicities overall between the 2 treatment groups. Conclusions: The current study indicates that Endostar as an anti-angiogenesis therapy combined with PBDC is able to provide further survival benefits with satisfactory toxicity in previously untreated squamous NSCLC patients, which merits further evaluation in randomized trials.

The Difference

Tumor recurrence is the most common cause of death in hepatocellular carcinoma (HCC) patients who received liver transplantation (LT). Recently, lenvatinib was approved for the systemic treatment of unresectable HCC patients; however, the role of lenvatinib in HCC patients after LT remains unclear. There were 56 patients with recurrent HCC after LT from 2008 to 2018 in our institute, and 10 patients who received lenvatinib were identified. Additionally, to understand the difference in the clinical impact of lenvatinib in the LT and non-LT settings, 25 HCC patients without LT who underwent lenvatinib treatment were identified from our HCC database and regarded as the control group. In the LT group, partial response was 20% and stable disease was 50%, resulting in a disease control rate of 70%; the median progression-free survival (PFS), time to treatment failure (TTF) and overall survival (OS) were 3.7, 3.6 and 16.4 months, respectively. Adverse events (AEs) were predominantly grade 1–2 in severity, and the majority of patients tolerated the side effects. There was no significant difference in PFS/OS, and we observed a similar pattern of AEs between these two groups. Our study confirms the comparable efficacy and safety of lenvatinib in HCC patients with LT and non-LT in clinical practice.

High Grade Osteosarcoma

Recent evidence implicates cell surface proteins of the tetraspanin superfamily in the process of metastasis whereas the downregulation of KAI-1, a member of the tetraspanin family, is associated with an aggressive clinical phenotype in several types of human cancers. To determine if expression of KAI-1-1 is associated with any known prognostic marker or clinical outcome in high-grade osteosarcoma, we examined 91 nondecalcified archival samples from 47 patients for the expression of KAI-1. Archival, paraffin-embedded, and decalcified pathologic samples were examined by immunohistochemistry and results were correlated to clinical outcomes and known prognostic markers. There were 46 samples from diagnostic biopsies (1 diagnostic sample was not available), 32 tumor resection samples, and 13 metastasis samples. Thirty-three percent (n = 30) of the samples expressed KAI-1 (16 biopsies, 9 resections, and 5 metastasis). KAI-1 expression was not significantly related to known prognostic markers or to either tumor necrosis after neoadjuvant therapy or the incidence of metastasis at diagnosis. KAI-1 expression was not significantly different between paired diagnostic tumor samples and either resection or metastasis tumor samples. Twenty-five patients remain alive at a median follow-up of 95 months. The overall and progression-free survival percentages at 5 years were 62% and 47% for KAI-1-positive patients and 49% and 38% for KAI-1-negative patients, respectively. This difference was not statistically significant. We conclude that KAI-1 is expressed in a proportion of high-grade osteosarcoma but is not of clinical significance and cannot be used to stratify treatment groups for these patients.

e14006 Background: Previous studies have shown that brain metastases of non-small cell lung cancer (NSCLC) with positive driver genes have poor prognosis. There is still lack of prospective studies on the efficacy and safety of targeted therapy combined with concurrent radiotherapy for brain metastases(BM). Methods: NSCLC patients, with ECOG score 0-2, having MRI confirmed brain or meningeal metastases were eligible. Patients must have driver gene mutation and received corresponding targeted therapy. The intracranial radiotherapy regimen was SRS or whole brain radiotherapy. The primary objective was iPFS (intracranial progression-free survival); Secondary objectives were: iORR (intracranial objective response rate), PFS (progression-free survival), OS (overall survival). MMSE (Mini Mental State Examination) and FACT-Br was carried out before/after weekly radiotherapy and during systematic treatment. Treatment-related toxicities were assessed according RTOG/EORTC criteria. Tumor responses were evaluated using RECIST V1.1 criteria. Survival analysis was performed using the Graphprism version 6.0 by Kaplan-Meier method and log-rank test. Results: 23 NSCLC with BM was included. Among them, 10 patients were newly diagnosed with NSCLC BM. 2 patients’ BM progressed after targeted therapy. 11 NSCLC patients were newly diagnosed with BM after targeted therapy. 91.3% of patients presented an EGFR mutation, including primarily EGFR 19-exon deletion, EGFR 21-L8585R. 11.5% presented with c-MET mutation. Median age was 58.34 yrs(44-71yrs). Patients were mostly treated with Erolotinib and Gefitinib. All patients were adenocarcinoma. At last follow-up, for patients newly diagnosed with NSCLC BM, 8 patients had achieved intracranial progression, and 7 patients had reached OS, of which 1 died before completing WBRT. The median iPFS was 9.3m(95%CI:0.571-4.055) and the median OS was 11.9m (95%CI:0.2752 -2.732). As for patients who progressed after targeted therapy, one patient’s OS was 4.4m, iPFS of the other patient was 3.9m. Among NSCLC patients who were newly diagnosed with BM after targeted therapy, 8 patients had achieved intracranial progression and 5 patients had reached OS. The median iPFS was 6.13m (95%CI:0.247-1.751) and the mOS was 13.8m (95%CI:0.3660-3.634). Common adverse effects include dry skin, fatigue, dizziness, headache, anorexia, and grade I myelosuppression and no serious adverse events (SAEs); MMSE and FACT-Br scores were no significant differences at baseline and follow-up. Conclusions: In stage IV brain metastatic NSCLC with driver gene mutation, targeted therapy combined with concurrent radiotherapy for BM is tolerable, and there is no significant impact on the quality of life and cognitive function after radiotherapy. The evaluation of efficacy requires further follow-up. Support:LC2019ZD009,81972853 and 81572279.

Clinical Trial Information

e20530 Background: Activated circulating endothelial cells (aCECs) have been indicated as a potential biomarker of angiogenesis in a variety of cancers. Several studies have revealed that aCECs may reflect the extent of tumor angiogenesis, and the level of aCECs counts may has correlation with progression-free survival (PFS) in anti-angiogenesis therapy on NSCLC patients. Therefore, we investigated the association between aCECs and PFS of Anlotinib treatment in ALTER-0303 study. Methods: NSCLC patients with aCECs counts in ALTER-0303 study were observed. Samples were prospectively collected at six time points: before treatment (baseline), on the 7th, 15th, 21th, 42th, 63thday of Anlotinib treatment. aCECs was identified by Flow cytometry (FCM). The prognostic value of aCECs counts was analyzed and, the patients were stratified according to their ratio of the minimum aCECs counts in all time points and counts on baseline (aCECs min/baseline) as <1 and ≥1. Results: Forty-nine patients were included of which 35 and 14 had an aCECs min/baseline<1 and ≥1, respectively in Anlotinib arm. Median follow-up was 8.6 months. In univariate survival analysis, patients with min/baseline<1 had longer PFS [HR=0.439, 95% CI (0.211-0.912), P = 0.023], the median PFS for the patients with aCECs min/baseline <1 and ≥1 were 193 days and 124 days, respectively (shown in Table). However, there were no significant relation between PFS and such aCECs min/baseline ratio found in control arm of ALTER-0303 study. Conclusions: A decrease of aCECs counts from baseline during an initial period of Anlotinib therapy may predict longer PFS and good response in NSCLC patients.

PurposeThymosin α 1 (Tα1) is an immunomodulatory polypeptide that enhances effector T-cell responses. In this large randomized study, we evaluated the efficacy and safety of combining Tα1 with dacarbazine (DTIC) and interferon alfa (IFN-α) in patients with metastatic melanoma.Patients and MethodsFour hundred eighty-eight patients were randomly assigned to five treatment groups: DTIC+IFN-α+Tα1 (1.6 mg); DTIC+IFN-α+Tα1 (3.2 mg); DTIC+IFN-α+Tα1 (6.4 mg); DTIC+Tα1 (3.2 mg); DTIC+IFN-α (control group). The primary end point was best overall response at study end (12 months). Secondary end points included duration of response, overall survival (OS), and progression-free survival (PFS). Patients were observed for up to 24 months.ResultsTen and 12 tumor responses were observed in the DTIC+IFN-α+Tα1 (3.2 mg) and DTIC+Tα1 (3.2 mg) groups, respectively, versus four in the control group, which was sufficient to reject the null hypothesis that P0≤ .05 (expected response rate of standard therapy) in these two arms. Duration of response ranged from 1.9 to 23.2 months in patients given Tα1 and from 4.4 to 8.4 months in the control group. Median OS was 9.4 months in patients given Tα1 versus 6.6 months in the control group (hazard ratio = 0.80; 9% CI, 0.63 to 1.02; P = .08). An increase in PFS was observed in patients given Tα1 versus the control group (hazard ratio = 0.80; 95% CI, 0.63 to 1.01; P = .06). Addition of Tα1 to DTIC and IFN-α did not lead to any additional toxicity.ConclusionThese results suggest Tα1 has activity in patients with metastatic melanoma and provide rationale for further clinical evaluation of this agent.

e16113 Background: Management of advanced hepatocellular carcinoma (HCC) remains a challenge. IMbrave150, a pivotal trial reported impressive overall survival benefit using combination strategy of atezolizumab and bevacizumab compared to sorafenib. We wonder the efficacy and safety when combining radiotherapy with immune checkpoint inhibitors (ICIs), which radiation might provide better local treatment and possible trigger abscopal effect. The aim of this study is retrospectively reporting the real-world efficacy and tolerability of proton beam or photon radiation plus ICIs in patients with advance stage HCC. Methods: We retrospectively reviewed all BCLC stage C HCC patients who have received combination therapy with ICIs plus proton or photon therapy with well documented basic characteristics and prompt treatment efficacy evaluation between 1st of January 2016 to 31st of October 2019 at a single medical center in Taiwan. 20 patients had ICIs plus proton and 32 patients had ICIs plus photon were included for analysis. Overall survival (OS) and progression free survival (PFS) were evaluated by Kaplan-Meier estimator. Results: Baseline characteristics were generally similar between ICIs plus proton or ICIs plus photon, while most patients in proton group did not receive prior systemic treatment and had less local therapies prior ICIs combine with radiotherapy. Median follow-up time was 10.7 months. The median Progression free survival (PFS) was not reached in ICIs plus proton group and 3.6 months (95% CI 2.7-4.6) in ICIs plus photon group (P = 0.007). The median OS was not reach in ICIs plus proton group and 12.1months (95% CI 6.4-17.7) in ICIs plus photon group (P = 0.007). Comparing ICIs plus proton group versus photon group, objective tumor response is 50% versus 9%, disease control rate is 80% versus 47% in each group. During follow-up, 7 patients (35%) in proton group achieved complete remission (CR). There was difference in radiation filed, 19 patients (95%) in proton group and 15 patients (47%) in photon group targeted on liver tumors, and more patient received > 50Gy treatment dose in proton group compared to photon group (90% versus 20%). Proton group has lower failure rate in both inner- or out-field compared to photon group. Grade 1 to grade 2 skin-dermatological and gastrointestinal toxicity remained the most frequent reported adverse events in both groups. There are only one therapy related grade 3 dermatitis in ICIs plus proton group and one grade 3 hepatitis, one grade 5 pneumonitis in ICIs plus photon group. Conclusions: This study reported real-world efficacy and safety of ICIs in combination with proton or photon therapy. Most adverse events were manageable. The combination of ICIs and proton therapy has impressive CR rate and OS benefit. Further prospective randomized trial is warranted for confirm our finding.

Objective: To explore the efficacy comparison between epidermal growth factor receptor–tyrosine kinase inhibitors (EGFR-TKIs) combined with traditional Chinese medicine (TCM) and single EGFR-TKIs for advanced non-small cell lung cancer (NSCLC).Methods: A total of 91 NSCLC patients with EGFR mutation were divided into an experimental group and a control group (in a ratio of 2:1) to receive TCM and EGFR-TKIs (61 cases) or single EGFR-TKIs (30 cases). Patients in the control group took EGFR-TKIs and those in the experimental group took EGFR-TKIs plus TCM. We analyzed the progression-free survival (PFS), overall survival (OS), disease control rate (DCR), and treatment-related adverse events of two groups.Results: The mPFS of the experimental group and the control group was 12.3 and 8.9 months (P = 0.02), respectively, and the mOS of the experimental group and the control group was 28.2 and 24.2 months (P = 0.02), respectively. Subgroup analysis showed that for the patients with exon 19 deletion mutation (19DEL), mPFS between experimental group and control group was 12.7 and 10.1 months, respectively (P = 0.12). For exon 21 deletion mutation (L858R), the PFS of two groups was 10.8 vs. 8.2 months, respectively (P = 0.03). The subgroup analysis also showed that, for the patients with exon 19 deletion mutation, mOS between the experimental group and the control group was 30.3 and 28.7 months, respectively (P = 0.19). For exon 21 deletion mutation, the mOS of two groups was 25.5 vs. 21.3 months, respectively (P = 0.01). The DCR of the experimental group and the control group was 93.3% and 80.1%, respectively (P = 0.77). Grade 3–4 treatment-related adverse events were less common with the experimental group (11.48%) than the control group (26.67%).Conclusion: For NSCLC patients with EGFR mutation, EGFR-TKIs combined with TCM had a certain effect to prolong mPFS and mOS, compared with the use of EGFR-TKIs alone, especially for the patients with L858R. This conclusion has a significant effect on improving the survival of NSCLC patients after EGFR-TKIs resistance. It deserves further study.

18043 Background: JMTO LC00–03, a randomized trial of VGD versus PC in patients with advanced NSCLC, showed differences between the two treatment groups in response rate (25 vs 37.1%) and regimens’ specific toxicities including taxane-related toxicities such as numbness (0 vs 16.2%) and neuropathy (0.5 vs 9.6%), but not in overall survival (MST, 13.6 vs 14.1 mos) and progression-free survival (MST, 5.5 vs 5.8 mos). (Kawahara et al, # 7013, ASCO, 2006). Methods: Patients with advanced NSCLC were randomly assigned to VGD or PC. The patients were assessed with Functional Assessment of Cancer Therapy- FACT-L and FACT-Taxane score in baseline, and at 6-, 12-, 18-weeks after the treatment. The longitudinal analysis was used to compare mean changes of the QOL score over the two treatment groups. Results: Sixty-eight patients from the trial (VGD: 34, PC: 34) who submitted both baseline questionnaire and at least one questionnaire over the course of the treatment were subjects of the study. The table presents the estimated changes in mean scores in treatment arms over the time period. The longitudinal analysis showed significant difference in FACT-Taxane (p<0.001) in the treatment over time, but no significant difference in the FACT-L score (p=0.261). The analysis assuming non-random missing mechanism resulted in slightly larger differences in the mean change. Conclusions: There was no statistically significant difference in FACT-L between the two groups, but VGD group was numerically better than PC group at any point from baseline. The significant difference in FACT-Taxane score favoring VGD would be due to the difference in frequency of neuropathy with docetaxel than with paclitaxel. [Table: see text] [Table: see text]

4086 Background: The combination of BEV and chemotherapy is highly effective in patients with mCRC and improves response rate, progression-free survival and overall survival compared with chemotherapy alone. This randomized non-comparative phase II trial evaluated the efficacy and safety of BEV in combination with either XELIRI or FOLFIRI as first-line therapy for mCRC. Methods: Patients were eligible for inclusion in this study if they had histologically proven measurable mCRC, were aged 18–75 years, and had an ECOG performance status (PS) of 0–2. Patients were treated with 8 cycles of XELIRI (irinotecan 200 mg/m2 on Day 1 and capecitabine 1000 mg/m2 bid on Days 1–14) + BEV 7.5 mg/kg on Day 1, every 3 weeks or 12 cycles of FOLFIRI (irinotecan 200 mg/m2 on Day 1 + 5-fluorouracil (5-FU) 400 mg/m2 + folinic acid 400 mg/m2 on day 1 followed by 5-FU 2400 mg/m2 via 46-h infusion) + BEV 5 mg/kg on day 1, every 2 weeks. BEV was continued to disease progression. Patients aged ≥65 years received a lower daily dose of capecitabine (800 mg/m2 bid). The primary endpoint was crude progression-free survival (PFS) at 6 months. Results: In total, 145 patients were entered in the study between March 2006 and January 2008; 72 patients received BEV + XELIRI and 73 patients received BEV + FOLFIRI (male 64%/48%; median age 61/61 years; 35/36% aged >65 years). Preliminary results from the first 6 months of follow-up are reported here. A total of 491/783 cycles was administered, 63%/67% receiving at least the initially planned number of cycles (8 cycles for BEV + XELIRI and 12 for BEV + FOLFIRI). Main results are given in the table . Conclusions: This randomized non-comparative study has shown that BEV + XELIRI and BEV + FOLFIRI are similarly effective treatments for patients with mCRC, with manageable toxicity profiles. Results with updated follow-up will be presented at the Meeting. [Table: see text] [Table: see text]

e18114 Background: Previous exploratory analysis of EGFR status in tumor samples from five LATAM countries suggested that frequency of mutations lies between that of Asian and Caucasian populations and therefore support the genetic heterogeneity of NSCLC around the world. Methods: We analyzed the EGFR sequence of tumor samples from advanced stage NSCLC patients previously participated in the CLICaP registry. We compared the outcomes (overall and progression free survival) of 175 patients (from Argentina, Colombia and México) with an activating EGFR mutation with 414 subjects without this condition. Results: Mutations were more frequent in women (57,1%), in patients who had never smoked (67,4%), and in those with adenocarcinomas (89,4%) (P<0,002 for all comparisons). The mutations were deletions in exon 19 (58,3%) and L858R (36%). Median progression-free survival and overall survival for 175 patients who received tyrosine-kinase inhibitors (TKIs) were 13-mo (95%CI 11,2-14,8) months and 36-mo (95%CI 25,4-46,5), respectively. TKIs produced higher response rates (used as first or second line therapy) in the EGFR mutation-positive patients (70,8% vs. 29,2%; P<0,001), as well as improved PFS (13,0 vs. 3,0; P<0,001). OS is significantly different between treatment groups (36 vs. 14; P<0,001). Conclusions: The analysis of a large comparative registry of Latin-American EGFR mutated and wild type patients confirms the results of individual clinical trials previously published.
