182 Background: Apatinib is a small molecule TKI inhibitor, which had been approved in China for treatment of advanced gastric cancer refractory to two or more lines of prior chemotherapy. Its efficacy and safety have been demonstrated in previous randomized controlled clinical studies. However, the efficacy and safety of apatinib in real world is lacking. This study aimed to evaluate the anti-tumor activity and toxicity of apatinib in real world. Methods: Patients older than 18 years with histologically diagnosed with gastric cancer were enrolled and treated with either apatinib alone or in combination with other drugs. The primary endpoint was progression-free survival (PFS), and secondary endpoints were overall survival (OS), overall response rate (ORR) and disease control rate (DCR). The adverse events were also recorded. Results: From March 2018 to March 2019, a total of 1000 patients were enrolled. Among them, 48(0.48%), 13(0.13%), 225 (22.5%), 389 (38.9%), and 325 (32.5%) patients received apatinib as postoperative auxiliary-, neoadjuvant-, first-, second-, and third- or higher line therapy, respectively. Efficacy evaluation was performed in 901 patients. Thirty-five patients achieved complete response (CR), 116 patients achieved partial response (PR), 596 patients achieved stable disease (SD), and 154 patients had progressive disease (PD), illustrating an ORR of 16.76% and a DCR of 82.91%. The mPFS was 5.32 months (95% CI, 4.93-5.75), and mOS was 9.76 months (95% CI, 8.97-10.81). In addition, the mOS of apatinib in first-line, second-line, and third-line treatments were 12.68 months, 9.49 months, and 7.62 months, respectively. Patients received apatinib in combination with other drugs had longer survival than apatinib alone, with mPFS 5.62 months vs 4.47 months and mOS 10.81 months vs 7.95 months. Such phenomenon was also observed in ORR (18.21% vs 13.04%, P< 0.001) and DCR (84.88% vs 77.87%, P< 0.001). The main adverse events (AE) were anemia (67.2%), thrombocytopenia (36.2%), leukopenia (34.5%)and anorexia (37.6%). The most common grade 3-4 adverse events included neutropenia, anemia and thrombocytopenia. Conclusions: In the real world, apatinib showed promising efficacy and manageable toxicities in patients with gastric cancer. Patients benefit more when received apatinib combination therapy. Clinical trial information: NCT03478943.

113 Background: Several randomized trials demonstrated the survival benefit in advanced gastric cancer patients (AGC pts) receiving irinotecan or taxanes as second-line chemotherapy (SLC). Taxanes are used for SLC in daily clinical practice in Japan because of its less toxicity, especially in AGC pts with peritoneal dissemination, compared with irinotecan. Although irinotecan is often administered after refractory or intolerant to taxanes as SLC, the efficacy and safety of irinotecan as third-line chemotherapy (TLC) is still unclear. Methods: We retrospectively investigated the data of AGC pts administered irinotecan 150mg/m2 as TLC every two weeks until disease progression, unacceptable toxicity, or pts’ refusal between December 2002 and June 2015. Inclusion criteria were (1) age 75 years or less (2) refractory or intolerant to fluoropyrimidine with or without platinum as first-line chemotherapy (3) refractory or intolerant to taxanes as SLC. Results: A total of 52 pts were analyzed. Pts’ characteristics were as follows: median age, 66 (range, 33-75) years; male/female, 35/17 pts; ECOG PS 0-1/2, 42/10 pts; peritoneal dissemination +/-, 32/20 pts; ascites +/-, 22/30 pts, number of metastatic sites 1-2/3-4, 44/8 pts. Median follow-up period was 548 (141-1931) days. Median progression-free survival was 70 days (95%CI 49-137) and median overall survival was 144 days (95%CI 120-231) from the initiation of irinotecan administration. Response rate and disease control rate was 10.8% and 50.4%, respectively. Relative dose intensity was 74.7% (56 mg/m2/week); 14 pts needed dose reduction in the first course, and 22 pts after the second course. Grade 3 or 4 neutropenia, anemia, diarrhea, nausea, and febrile neutropenia were observed in 13 (25%), 21 (40.4%), 5 (9.6%), 3 (5.8%) and 3 (5.8%) pts, respectively. No treatment-related death was observed. Conclusions: This study suggests that irinotecan monotherapy as TLC has acceptable anti-tumor effect and has manageable toxicity in appropriately selected AGC pts.

Abstract We evaluated the efficacy and safety of trifluridine/tipiracil (TAS-102) plus bevacizumab in treating refractory metastatic colorectal cancer (mCRC) in a retrospective, observational study. Patients refractory or intolerant to standard therapies received TAS-102 (30–35 mg/m2 twice daily on days 1–5 and days 8–12 every 28 days) plus bevacizumab 5 mg/kg on days 1 and 15. Clinical and pathological characteristics, overall response rate (ORR) and disease control rate (DCR), overall survival (OS) and progression-free survival (PFS) data were collected and analysed. Thirty-five patients were treated from July 2019 to October 2021 (median age 64 years). The majority of patients (68.6%) were receiving TAS-102 plus bevacizumab as third-line treatment. Patients received a median of 4 (range 2–15) cycles of treatment. Among 31 patients evaluable for response (88.6%), ORR and DCR were 3.2% and 51.6%, respectively. After a median 11.6 months’ follow-up, median PFS was 4.3 (95% confidence interval [CI] 3.4–5.1) months and median OS was 9.3 (95% CI 6.6–12.1) months. The most common grade 3–4 toxicities were neutropenia, asthenia and nausea/vomiting, and there were no treatment-related deaths. This real-world study confirms the efficacy and safety of TAS-102 plus bevacizumab in patients with refractory mCRC.

Objectives: The aim of this study was to investigate the role of nutritional factors in predicting radiotherapy-associated toxicities for gastric cancer patients. Methods: A total of 285 gastric cancer patients who underwent radiotherapy in our hospital between 2010 and 2017 were included in this retrospective study. Nutritional status assessment included body weight loss (BWL), body mass index (BMI), serum albumin, nutrition risk screening 2002(NRS-2002), patient-generated subjective global assessment(PG-SGA) and nutritional risk index (NRI). Results: Of all patients, 19.6% were underweight (BMI <18.5 kg/m2), 25.6% were hypoalbuminemia (<35 g l−1) and 48.8% lost ≥10% of body weight in the 6 month interval before radiotherapy(BWL). Meanwhile, 73.3%, 78.6 and 47.2% of the patients were diagnosed as malnutrition based on NRS-2002, PG-SGA and NRI, respectively. Hematological adverse events were present in 91.2% (≥Grade 1) and 20.4% (≥Grade 3) of the patients. Non-hematological adverse events occurred in 89.8% (≥Grade1) and 14.4% (≥Grade 3) of the patients. Multivariate analyses indicated that only hypoalbuminemia(<35 g l−1) was independent predictor for Grade 3/4 hematological and non-hematological adverse events. Meanwhile, higher BWL(≥10%) was also independent predictor for Grade 3/4 non-hematological adverse events. NRS-2002, PG-SGA and NRI score were not associated with treatment-induced adverse events. Conclusions: Body weight loss and serum albumin are useful factors for predicting severe adverse events in gastric cancer patients who undergo radiotherapy. Advances in knowledge: The use of nutritional factors in predicting severe adverse events enables implementation of individualized treatment strategies for early and intensive nutritional interventions in high-risk patients.

Abstract To study and observe the safety and efficacy of anlotinib in the treatment of advanced osteosarcoma with metastases. We retrospectively studied patients with advanced osteosarcoma and metastases who received anlotinib treatment in our hospital from June 2018 to April 2020. All patients had received standard multimodal therapies, before taking anlotinib. Therapeutic doses of anlotinib were 12 mg for adults and 10 mg for children and adolescents once a day for 2 consecutive weeks, followed by a week of withdrawal. This 3-week cycle of treatment was continued until the tumor progressed rapidly or the patients failed to tolerate the side effects. Adverse drug reactions were recorded, and therapeutic efficacy was evaluated based on progression free survival (PFS), disease control rate (DCR), overall survival (OS), and objective response rate (ORR). The median PFS was 9.81 ± 0.9 months, and the 6-month and 10-month PFS rates were 73.3% and 33.3%, respectively. The median OS was 11.43 ± 0.58 months. No patients achieved complete response. After 6 months of treatment, the DCR and ORR were 80% and 13.3%, respectively. No drug-related deaths or Grade 4 adverse events occurred in the patients. Five patients (33.3%) had Grade 3 adverse events. The most common drug-related adverse events were hand-food syndrome, fatigue, high blood pressure, anorexia, and pneumothorax. Anlotinib had a certain curative effect on patients with advanced osteosarcoma and metastases after failure of standard treatment. The adverse events were mostly tolerable or relieved after treatment.

Objective. To investigate the efficacy and safety of the treatment of the newly diagnosed multiple myeloma (MM) patients with the therapy of subcutaneous (subQ) administration of bortezomib and dexamethasone plus thalidomide (VTD) regimen.Methods. A total of 60 newly diagnosed MM patients were analyzed. 30 patients received improved VTD regimen (improved VTD group) with the subQ injection of bortezomib and the other 30 patients received conventional VTD regimen (VTD group).The efficacy and safety of two groups were analyzed retrospectively.Results. The overall remission (OR) after eight cycles of treatment was 73.3% in the VTD group and 76.7% in the improved VTD group (P>0.05). No significant differences in time to 1-year estimate of overall survival (72% versus 75%,P=0.848) and progression-free survival (median 22 months versus 25 months;P=0.725) between two groups. The main toxicities related to therapy were leukopenia, neutropenia, thrombocytopenia, asthenia, fatigue, and renal and urinary disorders. Grade 3 and higher adverse events were significantly less common in the improved VTD group (50%) than VTD group (80%,P=0.015).Conclusions. The improved VTD regimen by changing bortezomib from intravenous administration to subcutaneous injection has noninferior efficacy to standard VTD regimen, with an improved safety profile and reduced adverse events.

Abstract Introduction: Multiple myeloma (MM) is a plasma-cell malignancy and overall survival for patients who have relapsed after initial therapy is approximately 2 years. Bortezomib (VELCADE TM) is a first-in-class proteasome inhibitor that has demonstrated significant anti-tumor activity in MM patients. Here we report the results of an observational study of the efficacy and safety of bortezomib-based regimens in Chinese relapsed/refractory MM patients. Methods: This was a multi-center, open-label, phase IV observational study designed to enroll 550 patients with relapsed or refractory MM. From Mar 2006 to May 2008, 500 patients with relapsed or refractory MM were enrolled from 43 medical centers in China and 395 of them were evaluated. Bortezomib (0.7 to 1.6 mg/m2 i.v.) was given on days 1, 4, 8, and 11 in in a 21-day cycle, up to a maximum of 8 cycles, combined with other agents, mainly with the addition of dexamethasone (60.1%). Major endpoint included response rate, safety and time to response. Responses of 62% patients were determined by European Group for Blood and Marrow Transplantation criteria (EBMT). Bortezomib withheld if patients developed neutropenia fever, grade 4 haematologic adverse events (AEs), or grade 3 non-haematologic AEs, and re-administered at 75% of the initial dosage after recovery. Results: In 395 evaluable cases, the median age was 59 years (range 35–82) and the male/female ratio was 1.5:1. 90% of patients were in late stage(stage II/III) and 50% of them were IgG subtype. Patients had received various prior therapies before bortezomib treatment, including VAD (31.3%), VBMCP (M2, 15.1%) and thalidomide-based regimens(14.9%), with best response rate of 10.4% complete response (CR) and 42.3% partial response (PR) from prior therapies. 311 (82%) cases of patients received 1.0–1.4mg/m2 bortezomib-based regimens treatment and 38.5% of them received at least 4 cycles of treatment. 364 patients were evaluable for response, the overall response rate was 287/364 (78.8%), 89 patients (24.5%) achieved a CR, 30(8.24%) had a nearly complete response (nCR), 168 (46.2%) had a PR, 39 (10.7%) had minimal response (MR), 24 (6.6%) had stable disease (SD), and the other 14 (3.9%) had progressive disease (PD). Median time to response was 1 cycle of treatment (range 1–6). Patients who received 4 or more cycles of bortezomib treatment achieved a higher response rate (CR+PR: 81.5%) compared to those who received fewer cycles (partly due to adverse events). And prognosis-related analysis showed that the dosage of bortezomib at 1.0 mg/m2 or more had a significant influence on the time to response and response rate, but no obvious effect on response duration, time to progress or the survival time. Drug related adverse events (AEs) were reported in 50.4% of patients during treatment, including hematologic AEs (mainly thrombocytopenia, 22.5%), gastrointestinal AEs (24.8%), and peripheral neuropathy (22.5%). The rates of grade 3–4 AEs of them were 46.1%, 11.2% and 15.7%, respectively. Serious AEs occurred in 33 (8.4%) cases and 23 (70%) patients recovered finally. Most AEs were predictable and manageable. Conclusion: Bortezomib-based regimen is effective treatment with higher response rate and is well tolerated in most Chinese patients with relapsed and refractory MM patients. Long-term follow-up is continuing.

e15175 Background: Docetaxel, cisplatin, and 5FU (DCF) has been shown to be an effective regimen for metastatic gastric carcinomas. However, treatment-related adverse events is quite high with original dose DCF. We evaluated the outcomes of the metastatic gastric carcinomas who treated with modified dose DCF (mDCF) in our institution. Methods: A single institution retrospective review of patients with metastatic gastric cancer treated with three weekly mDCF from 1/2006 to 1/2013 was evaluated. Over this time period a standard order-set was in place in which cisplatin 60 mg/m2, 5FU 600 mg/m2 and docetaxel 60 mg/m2 was given three weekly. Tumor response was calculated retrospectively using RECIST criteria. Results: One hundred and ninety-one patients were included the study. The median age was 55 years (23 to 76), 74% were male, and 82% were chemo-naive. Eighty percent of the patients were metastatic at the time of diagnosis. The median number of cycles administered was 6 (2-10). Hematological toxicity was mild with grade 3/4 granulocytopenia in 25% of the patients, grade 3/4 thrombocytopenia in 4% of the patients, and grade 3/4 anemia in 9% of the patients. Neutropenic infection occurred in 9 (%5) patients. Grade 3/4 nausea/vomiting was reported by 10% of the patients, and diarrhea by 7%. A total of 19 (10%) patients had dose delays or dose reductions related to toxicity. Six (3%) patients had complete response and 43 (23%) patients had partial response. Stable disease were occurred in 83 (45%) patients and 56 (23%) progressive disease. Ninety percent of the patients have died with median follow-up of 8 months. Progression-free survival was 7 months (95% CI 6 to 7.8 m) and overall survival was 10 months (95% CI 8.7 to 11.2 m). Conclusions: mDCF has mild hematological toxicity and overall excellent tolerance in first line metastatic gastric cancer patients. Response rate and the survival of these patients with a minimal toxicity are comparable with the original dose DCF.

484 Background: The treatment of advanced biliary tract adenocarcinoma is based on chemotherapy with Gemcitabine with Cisplatin or Oxaliplatin in various combinations. After seeing the high efficacy of FOLFIRINOX regimen in advanced pancreatic cancers, we studied the efficacy and safety of a modified FOLFIRINOX regimen in advanced biliary tract adenocarcinoma. Methods: We retrospectively reviewed patient with advanced biliary tract adenocarcinoma who were treated with modified FOLFIRINOX regimen from April 2013 to March 2016 in a tertiary hospital. The schedule of modified FOLFIRINOX was - Oxaliplatin 85 mg/m2, Irinotecan 150 mg/ m2, Leucovorin 400 mg/m2, and 5 fluorouracil 2400 mg/m2given as a 46-hour continuous infusion, every 2 weeks. All patients received primary prophylactic growth factors. The objective was to evaluate the efficacy and safety of FOLFIRINOX regimen. Results: 20 patients with untreated advanced biliary tract adenocarcinoma were enrolled. The median age was 55 (range 31 to 66 years). All patients had good performance status. 2 patients had a complete response (10%), 8 patients had a partial response (40%), 5 patients had stable disease (25%) and 5 patients had progression (25%). The median progression free survival was 6 months and the median overall survival was 10 months. The major toxicities were grade 3/4 neutropenia (30%), oral mucositis (20%), fatigue (20%) and neuropathy (10%). Dose reduction was required in 30% patients. Conclusions: A modified FOLFIRINOX regimen is an effective regimen in good performance status patients with advanced biliary tract adenocarcinoma. Dose modifications are required to reduce toxicity of the regimen. It needs to be further studied in a phase 3 study in comparison to Gemcitabine based regimens.

11510 Background: IrAEs are associated with improved clinical outcomes after treatment with ICB in select epithelial malignancies. We hypothesized that sarcoma patients (pts) treated with ICB who developed an irAE would have improved outcomes compared to pts who had no irAE. Methods: Adverse events (AEs) from 3 sarcoma-specific ICB trials (nivolumab plus NKTR-214, pembrolizumab plus epacadostat, and pembrolizumab plus T-VEC) were reviewed. AEs probably or definitely related to ICB were classified as immune- or non-immune-related by the principal investigator. Endpoints of interest included best overall response (BOR) by RECIST 1.1 (complete response [CR]/partial response [PR]), durable clinical benefit (DCB; CR/PR/stable disease [SD] ≥ 16 weeks), and progression-free survival (PFS). Outcomes were stratified by the presence or absence of ≥ 1 irAE of any grade and by grade 1-2, grade 3-4, or no irAE (three-category comparison). Results: A total of 124 pts received ICB on these studies. Median pt age was 56 (range: 13-90); 53% were male; all but one pt had a performance status of ≤ 1. BOR was PR in 12 pts, SD in 41, and PD in 69. 2 pts were not evaluable. 40 pts (32%) had ≥ 1 irAE of any grade, 6 of whom had a grade 3-4 irAE. The most common irAEs (≥ 5% of pts) were rash (15%), arthralgia (11%), myalgia (9%), pruritis (8%), and hypothyroidism (6%). The proportion of pts with a CR/PR was higher in pts with than without an irAE (18% vs. 6%, respectively; P = 0.058). A significantly higher proportion of pts with an irAE had DCB compared to those without (53% and 29%, respectively; P = 0.017). The median PFS of pts with an irAE was 16.6 months compared to 10.6 in those without (P = 0.013). The proportion of pts with a grade 3-4 irAE and a CR/PR was highest (33%) compared to pts with grade 1-2 (15%) or no irAE (6%) (P = 0.048). More pts with grade 3-4 irAE achieved DCB (67%) than grade 1-2 (50%) or no irAE (29%) (P = 0.027). Median PFS was 22.6, 15, and 10.6 weeks in the grade 3-4, grade 1-2, and no irAE groups, respectively (P = 0.047). Conclusions: Approximately one-third of advanced sarcoma pts with ICB-based immunotherapy developed an irAE. As reported previously in select carcinomas, sarcoma pts with irAEs were more likely to have clinical benefit than those without irAEs. Further research is needed to understand the mechanism behind this association and to validate these findings prospectively.

e18562 Background: Although patients with locoregional advanced maxillary sinus squamous cell carcinoma (MSSCC) are often treated with surgery followed by postoperative radiotherapy (RT), the cosmetic and functional outcomes are unsatisfactory. Moreover, the efficacy and safety of intra-arterial chemoradiotherapy are controversial. Methods: In this study, we investigated the efficacy and safety of low-dose cisplatin administration through the superficial temporal artery (STA) combined with definitive RT in patients with MSSCC. Between January 2009 and December 2018, 57 patients were administered weekly intra-arterial infusions of cisplatin (30–50 mg/m2/5h) through the STA with simultaneous intravenous infusions of sodium thiosulfate. Overall response rate (ORR), local progression-free survival (LFS), maxillectomy-free survival (MFS), progression-free survival (PFS), overall survival (OS), and safety were evaluated retrospectively. The impact of clinical factors on survival was investigated using the Cox proportional hazard models. Results: The median follow-up time was 44 months (range, 10–80 months). There were 4, 26, 23, and 4 patients with cT2, cT3, cT4a, and cT4b, respectively. All patients completed the planned treatment except for one patient who discontinued owing to facial palsy. The ORR was 98% with 51 and 5 patients having complete and partial responses, respectively. The 3-year LFS, PFS, and OS were 74%, 63%, and 81%, respectively for all patients and 100%, 81%, and 94%, respectively for 22 patients received 70 Gy irradiation. Notably, the 3-year MFS was 95% for all patients and 100% in patients received 70 Gy RT. The most common grade 3 or more toxic event was oral mucositis (22.8%). Additionally, 4 (7.0%) patients had catheter-related infections. Late grade 3 or more adverse events included optic nerve disorder (8.8%), osteonecrosis (7.0%), encephalopathy (1.8%), and increased creatinine levels (1.8%). Salvage surgery including hard palate resection and orbital exenteration were performed in 2 and 1 patients, respectively. No clinical factor was correlated with survival outcomes in our study cohort. Conclusions: Low-dose cisplatin through STA combined with RT, especially 70 Gy RT, was associated with promising tumor response, high organ preservation rate, and tolerable adverse events in MSSCC patients. Further prospective studies are warranted to compare these outcomes with primary surgery.
