| 1 | Therapeutic perspectives for adult soft tissue sarcoma—updates from the 2022 ASCO annual meeting显示文摘At the recent 2022 American Society of Clinical Oncology(ASCO)annual meeting,the latest progress was presented in clinical trials of various therapeutic modalities for adult soft tissue sarcoma(STS),including chemotherapy,targeted therapy,anti-immune checkpoint immunotherapy,and multiple combination treatments(Table 1).Generally,the development of clinical treatments for STS is relatively slow,owing to the complex pathological subtypes of sarcoma and their heterogeneous biological behaviors.Here,we briefly summarize updates from this year’s ASCO meeting and discuss the future therapeutic perspectives for unspecific STS. | Jilong Yang Yu Xu Yong Chen Tao Li Xiaowei Zhang Tu Hu Ruwei Xing Yun Yang | 2022 | Cancer Biology & Medicine2022，19，10： | 0 |
| 2 | The efficacies and biomarker investigations of antiprogrammed death-1 (anti-PD-1)-based therapies for metastatic bone and soft tissue sarcoma显示文摘Objective:Sarcomas are a group of rare malignancies with various subtypes.Patients with metastatic sarcoma who have failed traditional treatments can possibly achieve better prognoses from using novel therapies,including anti-programmed death-1(PD-1)-based therapies.Methods:We retrospectively analyzed clinical data of 24 metastatic sarcoma patients from June 15,2016 to December 30,2019.These patients mainly received angiogenesis inhibitors combined with anti-PD-1 therapy after they became resistant to traditional treatments.Furthermore,8 patients underwent panel DNA and whole transcript sequencing.Results:Six patients received 2 cycles of anti-PD-1 therapy and were included in the safety evaluation only group.The median follow-up time was 5.77 months.The median progression-free survival was 7.59 months,the overall response rate was 16.7%and the disease control rate was 55.6%.Based on whole exome and transcript sequencing data,there was no association between TMB,TNB,MSI,HLA-LOH,and PD-L1 expressions and sarcoma types with clinical responses.Immunotherapy efficacy and bioinformatics analyses indicated higher intratumoral heterogeneity(ITH)in progressive disease(PD)patients and lower ITH in partial response(PR)and stable disease patients.A higher percentage of immune cell infiltration,especially monocytes,was observed in PR patients.Active stromal gene expression was increased in PD patients but decreased in PR patients.Enrichment analysis revealed that an increased TGF-βsignaling pathway was reversely correlated with anti-PD-1 efficacy,while a decreased inflammatory response signaling pathway was positively correlated with anti-PD-1 efficacy.Conclusions:Our study showed PD-1 inhibitors combined with anti-angiogenesis agents were effective and well-tolerated.ITH,monocyte ratio,stroma subtypes,and the status of immune-associated signaling pathways may be related with anti-PD-1 based therapy. | Jia Lu Ting Li Zhichao Liao Hui Yu Yongtian Zhao Haixiao Wu Zhiwu Ren Jun Zhao Ruwei Xing Sheng Teng Yun Yang Xiangchun Li Kexin Chen Jonathan Trent Jilong Yang | 2022 | Cancer Biology & Medicine2022，19，6： | 0 |
| 3 | Clinical study of apatinib in the treatment of stage IV osteogenic sarcoma after failure of chemotherapy显示文摘Objective:To analyze the efficacy and safety o f apatinib in the treatment of stage IV osteogenic sarcoma after chemotherapy failure through a single-arm,prospective,and open clinical phase II study.Methods:Information on 34 patients with stage IV osteogenic sarcoma treated with apatinib after failure o f chemotherapy in Tianjin Medical University Cancer Institute and Hospital between September 2015 and December 2019 was collected and analyzed.The participants included 23 males and 11 females,with an average age of 35.24 years(11-73 years).The objective response rate(ORR),disease control rate(DCR),progression-free survival(PFS),PFS rate(PFR),and overall survival(OS)were evaluated.The treatmentrelated adverse events(AEs)and safety of apatinib were also evaluated.Results:O f the 34 patients,33 were able to be evaluated for efficacy.One patient received apatinib treatment for less than one cycle;therefore,only safety analysis was performed.The 12-week clinical evaluation showed that 2 patients had a partial response(PR),24 patients had stable disease(SD),and 7 patients had progressive disease(PD).The ORR,DCR,and PFR at 12 weeks were 6.06%(2/33),78.79%(26/33),and 82%,respectively.By the end of the follow-up,6 patients had SD(18.18%,6/33),27 patients had PD(81.82%,27/33),and 15 patients died because of disease progression(45.45%,15/33).The ORR was 0(0/33),the DCR was 18.18%(6/33),and the median PFS(mPFS)was 7.89 months(95%Cl:4.56-11.21).The median OS(mOS)was 17.61 months(95%Cl:10.85-24.37).The most common treatment-related AEs were hand-foot syndrome(35.29%,12/34),proteinuria(32.35%,11/34),and hypertension(32.35%,11/34). | Zhichao Liao Ting Li Chao Zhang Xinyue Liu Ruwei Xing Sheng Teng Yun Yang Gang Zhao Xu Bai Jun Zhao Jilong Yang | 2020 | Cancer Biology & Medicine2020，17，2： | 0 |
