Introduction: Anlotinib, a novel multi-kinase inhibitor, was found to improve progression-free survival (PFS) in brain metastases.

Methods: This paper retrospectively analyzed 26 newly diagnosed or recurrent high-grade gliomas from 2017 to 2022, and the patients received oral anlotinib during concurrent postoperative chemoradiotherapy or after recurrence. Efficacy was evaluated according to the Response Assessment in Neuro-Oncology (RANO) criteria, and the main study endpoints were PFS at 6 months and overall survival (OS) at 1 year.

Results: After the follow-up, until May 2022, 13 patients survived and 13 patients died, with a median follow-up time of 25.6 months. The disease control rate (DCR) was 96.2% (25/26), and the overall response rate (ORR) rate was 73.1% (19/26). The median PFS after oral anlotinib was 8.9 months (0.8-15.1), and the PFS at 6 months was 72.5%. The median OS after oral anlotinib was 12 months (1.6-24.4), and the OS at 12 months was 42.6%. Anlotinib-related toxicities were observed in 11 patients, mostly grades 1-2. In the multivariate analysis, patients with Karnofsky Performance Scale (KPS) above 80 had a highermedian PFS of 9.9months (p = 0.02), and their sex, age, IDH mutation, MGMTmethylation, and whether anlotinib was combined with chemoradiotherapy or maintenance treatment had no effect on PFS.

Conclusion: We found that anlotinib combined with chemoradiotherapy in treating high-grade central nervous system (CNS) tumors can prolong PFS and OS and that it was safe.

Malignant triton tumor (MTT), a subtype of malignant peripheral nerve sheath tumor, is a rare soft-tissue sarcoma with a difficult diagnosis and poor prognosis. The course of MTT progression is rapid and the degree of malignancy is high. Patients with MTT can be treated with postoperative adjuvant radiotherapy and chemotherapy; however, treatment results are still poor.

To investigate whether blocking both programmed cell death protein and vascular endothelial growth factor receptor could offer superior anticancer activity in these patients without compromising safety. In this study, patients were administered oral anlotinib (12 mg/day) on days 1-14 and intravenous sintilimab (200 mg) on day 1 of a 3-weekly cycle. The primary endpoints included the objective response rate and disease control rate.

Article Synopsis
  • * The treatment showed a 37.5% objective response rate and an 85.0% disease control rate, with a median progression-free survival of 9.5 months and a 1-year overall survival rate of 73.3%.
  • * Common severe side effects included hand-foot syndrome (22.5%) and oral mucositis (17.5%), while circulating tumor DNA (ctDNA) analysis indicated its potential as a predictive biomarker for treatment response and disease progression.

Immune checkpoint inhibitors (ICIs) have gained widespread application in the treatment of malignant tumors. Cytokine release syndrome (CRS) is a systemic inflammatory response triggered by various factors, including infections and immunotherapy. We present a case of CRS occurring in a gastric cancer patient after receiving combination therapy of tislelizumab, anlotinib and combination of capecitabine and oxaliplatin.

Background: Immune checkpoint inhibitors (ICIs) have revolutionized the treatment of non-small cell lung cancer (NSCLC). TQB2450 (benmelstobart) is a novel humanized immunoglobulin G1 monoclonal antibody against programmed death-ligand 1 (PD-L1). Anlotinib, an oral multitargeted anti-angiogenic agent with potential synergy with ICIs, has shown efficacy in relapsed and advanced NSCLC.
