e16611 Background: HCC is one of the most common cancer among all the malignant tumor, while the efficacy of TACE alone for unresectable HCC patients still remains unsatisfactory. With the development of targeted drug, more and more targeted drugs are applying to the treatment of HCC. Objective: The aim of the stidy is to investigate the efficacy and safety of transarterial chemoembolization (TACE) combined with Anlotinib versus TACE alone in patients with unresectable HCC. Methods: This single-center retrospective study involved 82 patients with unresectable HCC who underwent TACE alone (TA group; n=46) or TACE combined with Anlotinib (TC group; n=36) between Jan 2018 and Jan 2019. The primary outcomes were progression-free survival (PFS) and overall survival (OS), while the secondary outcomes included the objective response rate (ORR), the disease control rate (DCR) and main complications. Results: The TC group showed relatively higher PFS than the TA group (7.35months vs. 5.54 months, p=0.035). The 3-month survival rate was not statistically different between the two groups (97.2% vs. 93.5%, p=0.627), while both the 6-month survival rate and 1-year survival rate were significantly higher in the TC group than in the TA group (83.3% vs. 56.5%, p=0.016; 66.7% vs. 19.6%, p<0.01). ORR in the TA group was significantly higher than in the TC group (77.8% vs. 32.6%, p<0.01), while the two groups showed no statistical difference in DCR (94.4% vs. 82.6%, p=0.17). No treatment-related mortality or grade 4 adverse event was observed, but grade 3 adverse events occurred in two patients in the TC group (one suffered with erythra, and another suffered with hand-foot-skin reaction). Both of them disappeared after prompt treatment. Conclusions: TACE combined with Anlotinib is safe and may improve outcomes for unresectable HCC patients comparing with TACE alone. It still needs more further randomized controlled trials to clarify the potential role of Anlotinib in hepatocellular carcinoma.

Objective: This study aimed to explore the efficacy and safety of using transarterial chemoembolization (TACE) combined with anlotinib in patients with unresectable hepatocellular carcinoma, compared with TACE alone. Methods: This was a single-center study, retrospectively recruited 82 unresectable HCC patients who received either TACE alone (TA group; n = 46) or TACE combined with anlotinib (TC group; n = 36) between Jan 2018 and Jan 2019. The primary outcomes were progression-free survival (PFS) and overall survival (OS). While the secondary outcomes were the objective response rate (ORR), the disease control rate (DCR), and main complications. Log-rank test and Kaplan–Meier method was used to calculate the survival difference. All statistical tests were 2-sided and P value <0.05 were taken as statistically significant. Results: Patients in TC group had a significant higher PFS than those in TA group (7.35 months vs. 5.54 months, p = 0.035). Although 3-month survival rate in the 2 groups was not statistically different (97.2% vs. 93.5%, p = 0.627), the survival rate at 6 months and 1 year were strongly higher in TC group (83.3% vs. 56.5%, p = 0.016; 66.7% vs. 19.6%, respectively, p < 0.05). Furthermore, there was a significantly higher ORR in TC group, while no statistical difference existed in DCR. Neither treatment-related mortality nor grade 4 adverse events (AEs) occurred. However, 2 patients in TC group had grade 3 AEs (one suffered with erythra, and the other with hand-foot-skin reaction), which disappeared after prompt treatment. Conclusion: TACE combined with anlotinib is safe and may improve outcomes for unresectable HCC patients comparing with TACE alone. Randomized controlled trials are warranted to further evaluate treatment effects of anlotinib in HCC.

e16127 Background: To evaluate the efficacy and safety of sorafenib or lenvatinib combined with sintilimab in patients with advanced hepatocellular carcinoma. Methods: This retrospective study included patients with advanced/metastatic hepatocellular carcinoma who received sintilimab (iv. 200 mg, Q3W) combined with sorafenib (oral, 400 mg twice-daily) (cohort A) or lenvatinib (oral, 12 mg/day for bodyweight≥60 kg or 8 mg/day for bodyweight < 60 kg) (cohort B) as first line therapy between March 2019 to December 2020 in the 5th medical center of the PLA general hospital of China. The primary endpoint was Progression-Free Survival (PFS), and the secondary endpoints included the Objective Response Rate (ORR), Disease Control Rate (DCR), Overall Survival (OS), Time to Progression (TTP) and safety. Results: 45 patients were enrolled, of which 29 were in the cohort A and 16 were in the cohort B. Except for the extrahepatic metastasis (62.1% vs 25.0%, P= 0.029), there were no significant differences in age, gender, weight, ECOG performance status, Child-Pugh, BCLC staging, and the proportion of previous treatment regimens between the two cohorts. The mean (±SD) exposure cycles in the two cohorts were 7.2±6.7 vs 7.1±4.7 ( P= 0.584). The median PFS of cohort A (8.2 months, 95%CI 3.1-19.5) was longer than that of cohort B (5.2 months, 95%CI 2.0-10.8), but there was no significant difference (HR 0.55, 95%CI 0.24-1.29, P = 0.161). However, there was no significant difference between the two cohorts in ORR (24.1% vs 6.3%, P= 0.226), DCR (82.8% vs 75.0%, P= 0.700) and median TTF (8.2 vs 4.6months, HR 0.49, 95%CI 0.21- 1.10, P= 0.074). OS data were not yet mature. There was no significant difference in the incidence of all grades and grade 3-4 adverse events between the two cohorts. The most common grade 3-4 adverse events in the two cohorts were hand-foot syndrome (17.2%, 5/29) and lung infection (12.5%, 2/16). There was 1 patient (immune hepatitis) in cohort A and 2 patients (pulmonary infection) in cohort B leading to treatment interruption due to adverse events, and no deaths due to treatment. Conclusions: Sorafenib or lenvatinib combined with sintilimab showed a good efficacy and safety in patients with advanced hepatocellular carcinoma, the safety and tolerability profiles were consistent with those previously observed. Sorafenib plus sintilimab provided an improved PFS versus lenvatinib, which requires a large sample of randomized controlled trial to confirm.[Table: see text]

<b><i>Background:</i></b> Lenvatinib has been recently approved as a first-line treatment option for patients with unresectable hepatocellular carcinoma (HCC) in Korea. We aimed to study the efficacy and safety of lenvatinib therapy in a real-world practice and to find prognostic factors related to survival and disease progression. <b><i>Methods:</i></b> A hospital-based retrospective study was conducted on 111 consecutive patients who had unresectable HCC and were treated with lenvatinib at Samsung Medical Center from October 2018 to March 2020. Efficacy was determined using the modified Response Evaluation Criteria in Solid Tumors (mRECIST) criteria in 111 patients who completed 1st tumor assessment. Safety was evaluated in 116 HCC patients including 5 patients who discontinued lenvatinib due to adverse events (AEs) before 1st tumor assessment using Common Terminology Criteria for AEs version 5.0. <b><i>Results:</i></b> A total of 111 patients with a median age of 59 years were analyzed during a median follow-up duration of 6.2 (4.4–9.0) months. The Kaplan-Meier estimate of overall survival was 10.5 months, and the median progression-free survival was 6.2 months. Based on mRECIST criteria, the objective response rate was 18.9% and disease control rate was 75.7%. AEs developed in 86/116 (74.1%) patients, and grade ≥3 AEs developed in 16/116 (13.8%) patients. Diarrhea, hand-foot skin rash, abdominal pain, hypertension, and anorexia were identified as the AEs with the highest frequencies of any grade. REFLECT eligibility criteria including tumor extent ≥50% liver occupation or inadequate bone marrow function and occurrence of anorexia were prognostic factors for survival, and occurrence of diarrhea was a favorable factor for disease progression. <b><i>Conclusion:</i></b> Lenvatinib therapy showed a favorable efficacy and safety in a real-world practice. The REFLECT eligibility criteria and specific AEs could be one of the prognostic markers.

Objectives: Previously, no therapeutic agent has been known to improve the overall survival compared with placebo in patients with hepatocellular carcinoma (HCC), who have progressed after sorafenib. In this patient population, regorafenib was first demonstrated to confer a survival benefit in the RESORCE trial, and subsequently it was approved as a second-line treatment for patients with advanced HCC. An open-label expanded access program (EAP) of regorafenib was implemented for compassionate use. We investigated the efficacy and safety of regorafenib based on our experience of the RESORCE trial and the EAP. Methods: Data from 5 patients from the RESORCE trial and 6 from the EAP were analyzed retrospectively. All patients had tolerated prior sorafenib and were progressing during sorafenib treatment. Results: The median progression-free survival was 9.2 months (95% CI 2.3-16.1). One patient achieved a partial response and 7 achieved stable disease. The objective response rate was 9.1%, and the disease control rate was 72.7%. No treatment-associated mortalities were observed. Grade 3 hypophosphatemia was observed in 2 patients, grade 2 anorexia was observed in 5 patients, and grade 3 neutropenia was observed in 2 patients. Grade 2 and grade 3 thrombocytopenia were observed in 2 and 3 patients, respectively. All treatment-related adverse events were improved by reduction or interruption of regorafenib. Five patients showed decreased serum albumin levels. Conclusion: Sorafenib and regorafenib sequential therapy presents a safe and effective treatment option for patients with advanced HCC.

287 Background: Transarterial chemoembolization either with Lipiodol (cTACE) or with drug eluting microspheres (DEM-TACE) is indicated for the treatment of hepatocellular carcinoma (HCC) not amenable to curative treatments in patients with preserved liver function. Safety of TACE is becoming more important with its increased use as a bridge to transplant or downstaging to resection, but also for preservation of liver function in case of subsequent immuno-combination therapies. LifePearl microspheres is a novel DEM comprised of polyethylene-glycol with reported good safety profile and efficacy in smaller series. Our purpose was to assess safety and efficacy of TACE using anthracycline loaded LifePearl for the treatment of patients with unresectable HCC in a pooled analysis of studies with available more than 500 patient’s level data. Methods: We pooled patient level data from 5 single arm studies. Safety was assessed by close monitoring of adverse events according to CTCAE (v4.03). Tumor response was assessed, according to mRECIST and RECIST1.1 and analyzed as best overall response to account for differences in time of imaging follow-up between studies. The Kaplan-Meier method was used to estimate event rates for time to event outcomes: progression free survival (PFS), time to unTACEable progression (TTUP) and overall survival (OS) censoring patients at time of surgery or transplantation. Results: Out of 586 patients, 85.5%, 13.5% and 1.0% were Child Pugh A, B and C, respectively. BCLC stages 0, A, B and C were 13.6%, 43.4%, 41.1% and 1.9% respectively. The mean number of HCC lesions was 2.1±1.5 and mean sum of tumor diameters was 49.3±32.9mm. In 19% of patients alpha-feto protein level was > 200ng/ml. A mean of 1.9±1.3 DEM-TACEs were performed per patient. A total of 197 events were reported including 2.6 % grade 4 and 1.5% grade 5, mostly related to post-embolization syndrome. Complete response, partial response and stable disease were 60.2%, 27.1% and 7.4% respectively providing an objective response and disease control rates of 87,3% and 94,7% respectively. 10% of patients were transplanted or resected. Median OS, PFS and TTUP is indicated in the table below. OS was 89.2%, 80.2% and 69.7% at 12, 18 and 24 months respectively. Conclusions: The treatment of patients with unresectable HCC with anthracycline loaded LifePearl showed good tolerance with acceptable toxicity and high tumor response rate that translated into promising PFS, TTUP and OS.

275 Background: The REFLECT trial establishedlenvatinib (LEN) as a first-line treatment option for hepatocellular carcinoma (HCC). Compared to sorafenib (S), LEN has a higher objective response rate (ORR) and progression-free survival (PFS) with a slightly different toxicity profile. The aim of this study was to gather data regarding the efficacy and safety of LEN when used in the real-world treatment of HCC. To our knowledge, this is the first study to examine LEN use in HCC patients treated outside of Asia. Methods: HCC patients treated with LEN from 10 cancer centers in the Canadian provinces of British Columbia, Alberta, Ontario and Nova Scotia between July 2018 to July 2020 were included. Overall survival (OS), PFS, disease control rate (DCR) and ORR were retrospectively analyzed and compared across first- and second-to-fourth line use of LEN. ORR was determined radiographically according to the treating physician´s opinion in clinical notes and not RECIST 1.1 or mRECIST. Toxicities were also examined. Results: A total of 220 patients were included in this analysis. Median age was 67 years, 80% were men and 25.5% East Asian. The most frequent causes of liver disease were hepatitis C (37%) and B (26%). 62% of patients received any localized treatment before LEN, of those 26% had TACE, 15% TARE and 7.7% had liver transplant. Before starting LEN 29% of patients were ECOG 0 and 59% were ECOG 1. Most patients were Child-Pugh A (81%) and BCLC stage C (75.5%). Main portal vein invasion was present in 14% of the patients. Median follow-up was 4.5 months. A total of 173 patients (79%) received LEN as first line therapy and 47 patients (21%) were treated in second-to-fourth line. Of patients receiving LEN in first line, 22 (13%) started treatment with S, but switched to LEN before progression due to poor tolerance of S. ORR, DCR, PFS and OS are shown in the table. Toxicities occurred in 86% of patients and led to dose reductions in 76 (35%) patients and drug discontinuation in 53 (24%) patients. The most common side effects were fatigue (59%), hypertension (41%), decreased appetite (25%) and diarrhea (22%). Conclusions: Outcomes of HCC patients treated in Canada with LEN in the first line are comparable to those demonstrated in the REFLECT trial, despite the inclusion of Child-Pugh B and ECOG >1 patients. LEN use in second or later lines also showed similar outcomes, although more conclusions are difficult to draw due to the small numbers. LEN appears to be effective and safe in real world practice outside of Asia in first- and second-to-fourth line treatment of HCC. [Table: see text]

Aims: The aim of this retrospective study is to evaluate the role of pulmonary metastasectomy (PM) in patients affected by lung metastasis (LM) of grade 2 and 3 chondrosarcoma (CS). Patients and Methods: The study included 61 patients affected by LM. Patients unfit for PM were treated with chemotherapy and radiotherapy. Results: The patients’ mean age was 51 years, ranging from 17 to 84 years; 44 (66.7%) patients had grade 2 CS, while 17 (25.8%) patients had grade 3 CS. Fifty-one patients presented multiple nodules: 44 of those cases were bilateral LM (72.1%). Twenty-nine (47.5%) patients underwent PM, whereas 32 (52.5%) patients underwent chemotherapy and stereotactic radiotherapy alone. At the final follow-up (average of 83 months, range 13–298), 47 (77.0%) patients had died of the disease. A better post-relapse survival rate was observed in patients who underwent PM (55.1 vs. 13.1% at 5-year follow-up, p < 0.001) and in patients with unilateral LM (60.4 vs. 25.6% at 5-year follow-up, p = 0.016). The number of LM also played a prognostic role. Conclusions: Until significant improvements in chemotherapy can be made, PM can be a valid option in the attempt to improve post-metastatic survival.

339 Background: Prior to the sorafenib era, most of the advanced hepatocellular carcinoma (HCC) patients had to rely only on conventional cytotoxic chemotherapy. But the introduction of sorafenib in 2008 had given HCC patients additional option for their treatment. However, given that sorafenib has been a nonreimbursable drug under the Korea public health system, most of treatment strategy has largely been determined by patients' affordability of the drug rather than by difference in efficacy and toxicity of the two treatments. Therefore, we compared the efficacy and toxicity of the two treatments by observing HCC patients. Methods: From January 2002 to December 2009, 173 patients with unresectable HCC had been retrospectively analyzed. Among them, 44 (25.4%) had been treated with sorafenib and the remaining had received cytotoxic chemotherapy. We evaluated objective response rate (ORR), progression-free survival (PFS), overall survival (OS), and toxicity profiles. Results: The median OS of sorafenib group was 23.0 weeks (95% CI, 8.1-37.9) vs. 43.6 weeks (95% CI, 34.0-37.9) for cytotoxic chemotherapy group. The median PFS for sorafenib group was 11.1 weeks (95% CI, 6.5-15.8) versus 12.4 weeks (95% CI, 8.1-16.7) for cytotoxic chemotherapy group. However, the difference in both findings had not been statistically significant (p=0.105 and p=0.496, respectively). ORR and DCR for sorafenib group were 2.3% and 52.3% versus 6.2% and 43.4% for cytotoxic chemotherapy group, respectively. Patients treated with chemotherapy had shown higher frequencies of grade 3 or 4 neutropenia, 19.7%, (vs. 0% for sorafenib). However, the group with sorafenib had reported a higher rate of all grade dermatologic toxicities such as hand-foot skin reaction, rash and pruritus. Conclusions: Our analysis indicates that efficacy of conventional chemotherapy is not inferior to that of sorafenib. Further research including novel target agent and cytotoxic chemotherapy is needed to improve clinical outcomes for advanced HCC. No significant financial relationships to disclose.

e15098 Background: The lungs may be the sole site of mets in RCC.In this retrospective analysis, we analyzed the efficacy and safety of SU in mRCC pts from a global phase (ph) III study and a Japanese ph II study who had lung mets only at baseline. Methods: In the ph III study, treatment (Tx)-naïve mRCC pts were randomized 1:1 to SU 50 mg/d on a 4-weeks-on-2-weeks-off schedule (n=375) or interferon-a (IFN) 9 MU subcutaneously TIW (n=360). In the single-arm ph II study, Tx-naïve (n=25) and cytokine refractory (n=26) mRCC pts received the same SU Tx. In the ph III study, progression-free survival (PFS) and overall survival (OS) were estimated by Kaplan–Meier method, with median values compared by log-rank test. In both studies, objective response rate (ORR) was calculated with a two-sided 95% CI. PFS, OS, ORR, and safety were analyzed at final data cutoff. Results: In the ph III study, 31 (8%) and 42 (11%) pts in the SU and IFN groups, respectively, had lung mets only, compared with 12 (24%) in the ph II study. Baseline characteristics in lung mets pts were similar to all pts. In lung mets pts from the ph III study, ORR was higher with SU than with IFN (58.1% [95% CI: 39.1–75.5] vs. 19.0% [95% CI: 8.6–34.1]; P<0.001); there was a trend for longer median PFS with SU (14.1 vs. 7.8 months; HR: 0.531 [95% CI: 0.278–1.015]; P=0.0513); and median OS was comparable in both Tx subgroups (HR: 0.739 [95% CI: 0.335–1.628]; P=0.4507), although, at 25% of events, median OS was 22.9 months with SU vs. 15.8 months with IFN. In lung mets pts from the ph II study, ORR was 75.0% (95% CI: 42.8–94.5); at the time of analysis, median PFS and OS had not been reached; 4 pts (33%) had died due to any cause and 8 (67%) were alive without disease progression. The most common grade ≥3 SU-related AEs were fatigue, hand-foot syndrome, and diarrhea (all 19%) in the ph III study, and decreased platelets (100%), white blood cells (92%), and neutrophils (92%) in the ph II study. Conclusions: In the ph III study, Tx-naïve mRCC pts with lung mets only had significantly higher ORR and a trend for improved PFS and OS with SU compared with IFN. In the Japanese ph II study, ORR with SU was 75% in lung mets pts. Thus, 1st-line use of SU in mRCC pts with lung mets should be encouraged.
