Project description:Purpose: Primary retroperitoneal liposarcomas (RLPSs) are rare heterogeneous tumors for which there are few effective therapies. Certain anti-angiogenic tyrosine kinase inhibitors have demonstrated efficacy against various solid tumors. The aims of this study were to investigate the effect of Apatinib against retroperitoneal liposarcoma cells and its underlying mechanism and to explore the anti-tumor efficacy of a combination of Apatinib and Epirubicin. Methods: SW872 cells were treated with Apatinib(18μM) for 24 h. The RNAs of the control group and experimental group were stored in TRIzol reagent at -80 ℃. Then mRNA extraction and RNA sequencing were performed by Beijing Mygenostics Co. Ltd., Beijing, China. A Bioanalyzer 2100 System (Agilent Technologies, Santa Clara, CA, USA) was used to assay RNA integrity. An AMPureXP system (BeckmanCoulter, Brea, CA, USA) was used to perform PCR on the products. Quality-tested library preparations were sequenced on the Illumina Novaseq platform (Illumina, San Diego, CA, USA). There were three biological replicates per condition. Differential expression analysis of both groups was performed using DESeq2R v. 1.20.0. The Benjamini-Hochberg multiple hypothesis test correction was performed to obtain the false discovery rate (FDR). The criteria used to select the DEGs were |log2(FoldChange)| > 0.5 and FDR < 0.05. When log2(FoldChange) > 0, the gene was considered upregulated. When log2(FoldChange) < 0, the gene was considered downregulated. profiler package in R (R Core Team, Vienna, Austria) was used for GO function and KEGG pathway enrichment analyses of the DEGs. Histograms and bubble graphs were plotted with the ggplot2 package in R v. 3.4.3. Results:To elucidate the mechanisms by which Apatinib inhibited liposarcoma cells, we used RNA-seq to evaluate relative genetic changes in the SW872 cells after being treated with Apatinib for 24 hs, and found 2,038 DEGs, including 1,059 significantly downregulated genes and 979 significantly upregulated genes. The output of the KEGG pathway enrichment analysis suggests that Apatinib might inhibit SW872 cell proliferation through p53, DNA replication, and other important signaling pathways. GO enrichment analysis was performed on the genes that were significantly altered after Apatinib application.High-throughput RNA sequencing showed that Apatinib downregulated the expression of TYMS and RRM2. Conclusions: Apatinib showed strong efficacy against liposarcoma both in vitro and in vivo. Apatinib might inhibit liposarcoma cell proliferation through the RRM2/PI3K/AKT/mTOR signaling pathway and downregulate PD-L1 via the TYMS/STAT3 signaling pathway.

Project description:PurposeTreatment options are limited after the failure of first-and second-line treatments in patients with HER2+ metastatic gastric cancer (mGC). The present study aimed to explore the efficacy, safety, and prognostic factors of apatinib efficacy as a third-line therapy for patients with human epithelial growth factor receptor 2-positive (HER2+) mGC.Materials and methodsA total of 59 HER2+ mGC patients who received apatinib as third-line therapy were retrospectively enrolled in this two-center, single-arm, cohort study; the clinical response, survival data, and adverse events were retrieved.ResultsThe median progression-free survival (PFS) was 5.2 months (95% confidence interval [CI], 3.9-6.5), and the median overall survival (OS) was 8.2 months (95% CI, 6.6-9.8) Furthermore, forward stepwise multivariate Cox regression analysis showed that a higher Eastern Cooperative Oncology Group performance status score and multiple metastases were independently correlated with decreased PFS and OS (both P<0.05). The main adverse events were leukopenia (45.8%), hypertension (44.1%), thrombocytopenia (39.0%), hand-foot syndrome (37.3%), and elevated transaminase (33.9%). Grade 3 adverse events mainly included hypertension (5.1%) and neutropenia (5.1%); grade 4 adverse events did not occur.ConclusionsApatinib is efficient and well tolerated in patients with HER2+ mGC as a third-line treatment, suggesting that it may be a candidate of choice for these patients.

Project description:Targeted therapy for patients with EGFR mutations by tyrosine kinase inhibitors (TKIs) has provided a significant benefit to patients. However, gradually developed resistance to the therapy becomes a major challenge in clinical practice. Herein, we report that Apatinib, an anti-angiogenic drug, strongly and specifically inhibits Gefitinib-resistant cancer cells but not their parental sensitive cells. Gefitinib-resistant lung cancer cell line (PC9GR) was established from its parental sensitive line (PC9) with a traditional EGFR mutation after long time exposure to Gefitinib. The established PC9GR cells had over 250 fold increased resistance to Gefitinib than its sensitive parental PC9 cells. Apatinib demonstrated much stronger (~5 fold) growth inhibition on PC9GR cells than on PC9 and other lung cancer cell lines. This inhibition was mostly achieved through cell cycle rest in G1 phase as demonstrated by transcriptome and protein expression data. Oral intake of Apatinib in mouse model significantly inhibited establishment and growth of PC9GR implanted tumors. VEGFR2 phosphorylation in PC9GR tumors after Apatinib treatment was significantly reduced along with less micro-vessel formation. Apatinib may provide a benefit to patients with acquired resistance to TKI treatment.

Project description:BackgroundThe prognosis for esophageal cancer (EC), a common malignant tumor, is poor. The new oral small-molecule tyrosine kinase inhibitor apatinib has shown an excellent therapeutic effect on treating EC. Camrelizumab is a humanized programmed death 1 (PD-1) inhibitor with high affinity. Immune checkpoint inhibitors combined with chemotherapy have become the standard first-line treatment for advanced EC. The new combination strategy of anti-angiogenic therapy combined with immunotherapy has great application prospects in the treatment of tumors. We aimed to assess camrelizumab in combination with apatinib as a new combination regimen for advanced or metastatic esophageal squamous cell carcinoma (ESCC).MethodsIn this study, we recruited patients with an Eastern Cooperative Oncology Group (ECOG) performance status ≤2, with pathologically confirmed unresectable, locally advanced, locally recurrent, or metastatic ESCC. Each patient received an intravenous infusion of camrelizumab 200 mg and oral administration of apatinib 250 mg once a day, every 21 days, as a cycle until disease progression, intolerance, or death. The primary endpoint was the objective response rate (ORR), while the Kaplan-Meier method and LIFETEST procedure were used to estimate survival functions for overall survival (OS) and progression-free survival (PFS). The National Cancer Institute Common Terminology Criteria for Adverse Events, version 4.03, was used to evaluate adverse events.ResultsBetween December 1, 2019 and July 31, 2022, 35 patients were enrolled, with 29 patients in the efficacy and safety analysis. The ORR was 34.5%, and the disease control rate (DCR) reached 82.8%. Median OS was 13.8 months (95% CI: 11.2-16.2), and the estimated 6-, 9-, and 12-month OS rates were 85.5% (95% CI: 65.7-94.3%), 80.9% (95% CI: 60.3-91.5%), and 67.0% (95% CI: 43.8-82.4%), respectively. Median PFS was 9.5 months (95% CI: 7.0-13.6). The most prominent grade ≥3 adverse events associated with treatments were alanine aminotransferase (ALT) increase (10.3%), hypertension (10.3%), and reactive cutaneous capillary endothelial proliferation (CCEP) (6.9%), and no deaths occurred due to adverse events.ConclusionsAmong patients with advanced or metastatic ESCC, camrelizumab combined with apatinib showed a reasonable remission rate and survival benefit with a manageable safety profile.

Project description:Angiogenesis inhibitors are of considerable interest for treating metastatic colorectal cancer (mCRC). This trial evaluated the efficacy and safety of apatinib in chemotherapy-refractory mCRC. Apatinib 500 mg was administered daily to patients who had progressed after two or more lines of standard fluorouracil-based chemotherapy. Primary endpoint was progression-free survival (PFS). Secondary endpoints were objective response rate (ORR), disease control rate (DCR), overall survival (OS), and toxicity. Overall, 48 patients were enrolled. ORR and DCR were 8.3% (4/48) and 68.8% (33/48), respectively. Median PFS and OS were 4.8 (95% confidence interval [CI], 3.653-5.887) and 9.1 months (95% CI, 5.155-13.045), respectively, and did not differ between subgroups stratified by previous anti-angiogenic therapies. The most prevalent grade 3-4 adverse events were hypertension (12.5%), hand-foot syndrome (HFS, 10.4%), thrombocytopenia (10.4%), and proteinuria (8.3%). Low baseline neutrophil/lymphocyte ratio (NLR, hazard ratios [HR], 0.619; P = 0.027), early carbohydrate antigen 19-9 (CA19-9) decrease (HR, 1.654; P = 0.016), and HFS (HR, 2.087; P = 0.007) were associated with improved PFS. In conclusion, apatinib monotherapy demonstrated encouraging efficacy with manageable toxicities in chemotherapy-refractory mCRC. Previous anti-angiogenic therapies did not influence outcomes. Baseline NLR, early CA19-9 decrease, and HFS could predict the efficacy of apatinib.

Project description:BackgroundApatinib, a small-molecule tyrosine kinase inhibitor that selectively targets vascular endothelial growth factor receptor-2, has clinical activity in recurrent/advanced gynecological cancers. However, its efficacy in uterine malignancy remains unclear. This study aimed to determine the efficacy and safety of single-agent apatinib in patients with recurrent uterine malignancy.MethodsThis is a prospective single-center, single-arm, phase 2 study that enrolled patients aged 18-70 years with histopathologically confirmed recurrent endometrial cancer (EC) and recurrent uterine sarcoma (US), received at least 2 chemotherapy regimens, and an Eastern Cooperative Group performance status of 0-1. Apatinib (500 mg) was administered orally once daily. A treatment cycle was defined as 4 weeks. The patients were followed up every 2 cycles for tumor radiological assessment until disease progression. The primary endpoint was the overall response rate (ORR). The secondary endpoints were progression-free survival (PFS) and overall survival (OS). Adverse events (AEs) were recorded throughout the treatment and within 30 days of the last study treatment and graded as per the National Cancer Institute Common Toxicity Criteria Version 4.0.ResultsA total of 33 patients (22 with EC and 11 with US) were enrolled between October 2018 and April 2021. Median follow-up duration was 11.7 months (interquartile range: 6.8-32.5 months). The patients received apatinib for a median of 4.79 cycles (range 2-13 cycles). In the EC and US cohorts, the ORRs were 27.2% [95% confidence interval (CI), 10.7% to 50.2%] and 9.1% (95% CI, 0.2% to 41.3%), the median PFS were 4.4 months (95% CI, 4.2 to 6.7 months) and 7.0 months (95% CI, 3.2 to 11.6 months), and the median OS were 11.7 months (95% CI, 6.8 months to not reached) and 18.1 months (95% CI, 9.2 months to not reached), respectively. The most common treatment-related AEs of all grades were hypertension (36.4%), proteinuria (33.3%), and hand-foot syndrome (30.3%). No treatment-related serious AEs or deaths occurred.ConclusionsTo our knowledge, this is the first prospective study assessing the efficacy and safety of apatinib in patients with uterine malignancy. The results suggested that apatinib might be a potential treatment option for these patients.

Project description:PurposeThis study aims to investigate the efficacy and safety of transcatheter arterial chemoembolization (TACE) combined with Apatinib and Camrelizumab for treating unresectable advanced gastric or gastroesophageal junction (G/GEJ) cancer.Material and methodsIn this study, data of patients with unresectable advanced G/GEJ cancer who received TACE combined with Apatinib and Camrelizumab from August 2018 to December 2021 was evaluated. After TACE, patients were given intravenous Camrelizumab 200mg every three weeks and oral apatinib 250mg/day for treatment. The primary endpoint was overall survival (OS), and the secondary endpoints were objective response rate (ORR), disease control rate (DCR), and adverse events (AEs).ResultsA total of 49 patients were enrolled in this study. The median follow-up time was 14.0 months, and the median OS was 20.0 months (95% CI = 13.6-26.4). Two patients (4.08%) achieved complete remission, 28 patients (57.14%) achieved partial remission, 18 patients (36.73%) had stable disease, and 1 patient (2.04%) had disease progression. The ORR was 61.22%, and the DCR was 97.96%. Multivariate Cox regression analysis indicated that age (HR 4.74, 95% CI = 1.674-13.440, P=0.003) and multiple distant metastases (HR 20.916, 95% CI = 4.094-106.808, P = 0.001) were independent risk factors for OS. Most AEs were classified as grade 1-2, the most common being RCCEP (69.39%). There were 5 cases of grade 3-4 adverse events (10.20%). No patients discontinued or reduced the treatment dose due to AEs, and all patients received symptomatic treatment.ConclusionTACE combined with Apatinib and Camrelizumab is a safe and effective therapeutic option for patients with unresectable advanced G/GEJ cancer, which can significantly improve the median OS and ORR of patients. And the adverse events (AEs) are tolerable and manageable.

Project description:BackgroundApatinib improves progression-free survival and overall survival with an acceptable safety profile in Chinese patients with chemotherapy-refractory advanced or metastatic gastric cancer. However, the efficacy and safety of apatinib are unclear for elderly patients. This study was undertaken to prospectively investigate the efficacy and safety of apatinib for elderly patients with unresectable advanced or metastatic gastric cancer, who experienced progression to at least one lines of chemotherapy.MethodsThis open-label, single-arm, phase II study enrolled patients aged ≥60 years with advanced gastric cancer, who experienced progression to one or more lines of chemotherapy at five centers in China. Patients received apatinib in an oral dose of 500mg or 250mg daily according to the research physicians' decision. The primary end point was progression-free survival, and the secondary end points were objective response rate, disease control rate, overall survival, and safety.ResultsForty-eight patients were enrolled between June 2017 and September 2019. The median age was 65.5 years (range 60-80 years). Twenty-seven patients (56.3%) started treatment with an initial dose of 500 mg and 21 patients (43.7%) with 250 mg. The median progression-free survival and overall survival were 3.00 months (95% confidence interval, 2.17-3.84) and 8.10 months (95% confidence interval, 4.35-11.85), respectively. The objective response rate and disease control rate assessed by the investigators were 16.7% and 72.9%, respectively. The common side effects were fatigue (58.3%), hypertension (47.9%), abdominal pain (33.3%), proteinuria (29.2%), leukopenia (22.9%), and neutropenia (20.8%). Hypertension (22.9%) was the major grade 3/4 toxicity.ConclusionThese data suggest that apatinib is effective and relatively tolerable for elderly patients with unresectable advanced or metastatic gastric cancer who have received at least first-line chemotherapy.
