Apatinib in gastric carcinoma: A case report of partial response for first‐line treatment in advanced disease

Gastric cancer (GC) is the most common gastrointestinal malignant tumor, with a gradual increasing incidence throughout the world. Mostly GC is diagnosed in its late stage. To date, there is no usable standardized treatment regimen for patients with advanced GC. Apatinib mesylate, small‐molecule vascular endothelial growth factor receptor‐2 (VEGFR‐2) tyrosine kinase inhibitor (TKI), has been approved as third‐line treatment for patients with advanced gastric adenocarcinoma in China, October, 2014. Till now, there is no case report about apatinib as first‐line treatment for patients with advanced GC in literature. We present an 83‐year‐old Chinese man with advanced gastric adenocarcinoma, who received apatinib as first‐line option and obtained clinical benefit within 2 weeks. The lung metastases disappeared completely and the liver metastases shrank significantly. The patient's progression‐free survival was 163 days and overall survival was 201 days. This paper reviews and discusses apatinib as a new targeted drug for patients with advanced GC by comparison with other effective molecular‐targeted therapy.

Successful treatment using apatinib with or without docetaxel in heavily pretreated advanced non-squamous non-small cell lung cancer: A case report and literature review

Although targeted therapy directed toward driver mutations has produced a significant efficacy benefit for patients with non-small cell lung cancer (NSCLC), many patients do not possess mutations associated with the approved targeted drugs. Angiogenic agents play an important role in the therapeutic strategy for advanced NSCLC. Apatinib is a novel tyrosine kinase inhibitor that targets vascular endothelial growth factor receptor-2. A phase II clinical trial demonstrated the survival benefit of apatinib monotherapy in advanced NSCLC. Moreover, addition of anti-angiogenic agents to chemotherapy showed robust efficacy in advanced NSCLC, regardless of tumor histology. Here, we present the case of a heavily pretreated lung adenocarcinoma patient who was treated with apatinib and apatinib continuation plus docetaxel re-challenge. He was negative for several driver genes, including EGFR, ALK, KRAS, ROS1, HER2, RET and BRAF. The previous treatment included platinum-based doublets, pemetrexed monotherapy, docetaxel plus bevacizumab, gefitinib monotherapy, nab-paclitaxel monotherapy, irinotecan plus oxaliplatin and radiotherapy. He obtained a partial response after both apatinib monotherapy and apatinib plus docetaxel treatment, with progression-free survival durations of 5 months and 6 months, respectively. This case indicated that apatinib monotherapy or apatinib plus docetaxel might be regarded as a therapeutic option for heavily pretreated patients with advanced non-squamous NSCLC.

Apatinib Monotherapy or Combination Therapy for Non-Small Cell Lung Cancer Patients With Brain Metastases

Apatinib, an oral small molecular receptor tyrosine kinase inhibitor (TKI) developed first in China, exerts antiangiogenic and antineoplastic function through selectively binding and inhibiting vascular endothelial growth factor receptor 2 (VEGFR-2). In this study, we aimed to explore the efficacy and safety profile of apatinib monotherapy, or combined with chemotherapy or endothelial growth factor receptor (EGFR)-TKI in heavily pretreated non-small cell lung cancer (NSCLC) patients with brain metastases. We performed a retrospective analysis for relapsed NSCLC patients with brain metastases from our institute, who received apatinib (250 mg or 500 mg p.o. qd) monotherapy, or combination with EGFR-TKI or chemotherapy as second or more line systemic therapy until disease progression or unacceptable toxicity occurred. The objective response rate (ORR), disease control rate (DCR), median progression-free survival (mPFS), median overall survival (mOS), and safety were analyzed. A total of 26 eligible patients were included: 24 patients diagnosed with adenocarcinoma, 2 with squamous carcinoma, and 14 patients harboring EGFR sensitizing mutations. The mPFS and mOS were 4.93 (range, 0.27−32.91; 95% CI 3.64−6.22) and 14.70 (range, 0.27−32.91; 95% CI 0.27−43.60) months for the whole group. The ORR and DCR were 7.7% (2/26) and 69.2% (18/26) for the entire lesions, and 7.7% (2/26) and 79.6% (20/26) for brain metastases, respectively. Compared with patients who received apatinib monotherapy, patients who received apatinib combination treatment had more favorable mPFS (11.77 vs. 2.27 months, p<0.05) and mOS (24.03 vs. 6.07 months, p<0.05). Treatment-related toxicities were tolerable including grade 1/2 hypertension, hand-and-foot syndrome, fatigue, nausea, liver dysfunction, myelosuppression, skin rash, and palpitation. In conclusion, apatinib exhibited high activity and good tolerance for NSCLC patients with brain metastasis, and it might become a potential choice for metastatic brain tumors in NSCLC patients.     

Tumor progression-dependent angiogenesis in gastric cancer and its potential application

Despite improvements in the early diagnosis, prognosis and therapeutic strategies for gastric cancer (GC), human GC remains one of the most frequently diagnosed malignant tumors in the world, and the survival rate of GC patients remains very poor. Thus, a suitable therapeutic strategy for GC is important for prolonging survival. Both tumor cells themselves and the tumor microenvironment play an important role in tumorigenesis, including angiogenesis, inflammation, immunosuppression and metastasis. Importantly, these cells contribute to gastric carcinogenesis by altering the angiogenic phenotype switch. The development, relapse and spreading of tumors depend on new vessels that provide the nutrition, growth factors and oxygen required for continuous tumor growth. Therefore, a state of tumor dormancy could be induced by blocking tumor-associated angiogenesis. Recently, several antiangiogenic agents have been identified, and their potential for the clinical management of GC has been tested. Here, we provide an up-to-date summary of angiogenesis and the angiogenic factors associated with tumor progression in GC. We also review antiangiogenic agents with a focus on the anti-vascular endothelial growth factor receptor (VEGFR)-mediated pathway for endothelial cell growth and their angiogenesis ability in GC. However, most antiangiogenic agents have reported no benefit to overall survival (OS) compared to chemotherapy alone in local or advanced GC. In phase III clinical trials, only ramucirumab (anti-VEGFR blocker) and apatinib (VEGFR-TKI blocker) have reported an improved median overall response rate and prolonged OS and progression-free survival outcomes as a 2nd-line agent combined with chemotherapy treatment in advanced GC. By providing insights into the molecular mechanisms of angiogenesis associated with tumor progression in GC, this review will hopefully aid the optimization of antiangiogenesis strategies for GC therapy in combination with chemotherapy and adjuvant treatment.     

Neoadjuvant intraperitoneal and systemic paclitaxel combined with apatinib and S-1 chemotherapy for conversion therapy in gastric cancer patients with positive exfoliative cytology: a prospective study

BackgroundTo explore the efficacy and safety of neoadjuvant intraperitoneal and systemic (NIPS) paclitaxel chemotherapy combined with apatinib and S-1 in the treatment of gastric cancer patients with positive exfoliative cytology.MethodsPatients with gastric cancer (P₀CY₁) who were confirmed to have free cancer cells (FCCs) in the abdominal cavity after laparoscopic exploration from April 2018 to August 2019 were enrolled. All patients underwent NIPS chemotherapy using paclitaxel combined with apatinib and S-1 treatment. Laparoscopic exploration was performed after 3 cycles of conversion therapy. The primary study endpoint was the FCC negative rate, and the secondary study endpoints were overall survival time (OS), progression-free survival time (PFS), objective response rate (ORR), disease control rate (DCR), and safety indicators.ResultsOut of 312 advanced gastric cancer patients who underwent laparoscopic exploration, 36 patients with P₀CY₁ gastric cancer were identified and enrolled in this study. After 3 cycles of conversion therapy, the ORR was 80.56% and the DCR was 94.44%. All patients underwent secondary laparoscopic exploration, and the FCC conversion rate was 77.78%. All patients with negative FCC underwent R0 surgical resection, with a median follow-up time of 11.4 months. The median survival time was 15.5 months, and the 1-year OS was 80.55%. The median PFS was 14.4 months, and the 1-year PFS was 75.00%. Treatment-related grade 3 adverse reactions were mainly leukopenia and neutropenia. No grade 4 adverse reactions were observed. There were no reported deaths related to chemotherapy or surgery in the study cohort.ConclusionsNIPS with paclitaxel combined with apatinib and S-1 treatment may increase the FCC negative rate of P₀CY₁ gastric cancer patients.

Apatinib plus ifosfamide and etoposide for relapsed or refractory osteosarcoma: A retrospective study in two centres

For osteosarcoma that progresses following first-line chemotherapy, prognosis remains poor although anti-angiogenesis tyrosine kinase inhibitors (TKIs) have been verified to prolong progression-free survival. Apatinib has led to positive responses in the treatment of refractory osteosarcoma. However, it demonstrates only short-lived activity, and the disease control rate of musculoskeletal lesions is worse compared with that of pulmonary lesions. This treatment failure has been partly overcome by the addition of ifosfamide and etoposide (IE). The present study retrospectively compared the activity of apatinib + IE in relapsed or refractory osteosarcoma in two sarcoma centres in China. The included patients had received a combination of apatinib 500 mg (orally) daily and the IE regimen (n=33) between June 3 2017 and July 17 2020. The tumour burden was considerable in these patients: 16/33 (48.5%) Patients had lung and musculoskeletal lesions, and 31/33 (93.9%) patients had progressed to two lines of therapies at baseline. With a median follow-up duration of 28.4 [interquartile range (IQR), 16.1–38.3] months, 21/33 (63.6%) patients had objective responses, and the median event-free survival was 11.4 (IQR, 6.7–18.4) months. The median overall survival time was 19.8 (IQR, 13.1–30.6) months. At the last follow-up, 16/33 patients had tumour downstaging, and all lesions had been completely resected. For osteosarcoma with multiple sites of metastasis, apatinib + IE demonstrated clinically meaningful antitumor activity and delayed disease progression in patients with recurrent or refractory osteosarcoma after failure of chemotherapy. This combination with manageable toxicity deserves further investigation in prospective trials.

The clinicopathological features, treatment and survival of gastric adenocarcinoma in Omani Arab patients

Background: Gastric carcinoma (GC) is the second most frequent cancer worldwide and the most common cancer in the Sultanate of Oman. The surgical and medical management of GC varies worldwide, and variable ethnic differences in clinicopathological features and survival have been observed. The aim of this work was to study clinicopathological features, management and survival trends of GC in Oman and to assess the impact of aggressive management trends on survival. Methods: A retrospective study of gastric adenocarcinoma cases, treated at three main hospitals in Oman over a 12‐year period, was undertaken. The study was divided into period I (1993–1998) and period II (1999–2004), based on the evolution of cancer services. Results: A population of 339 patients was included in the study (M : F ratio 1.9 : 1). GC was mainly a disease of elderly males with mean ages of 60.3 and 59.3 years for periods I and II, respectively. The most prevalent types of GC observed during periods I and II were distal (60.7% vs. 57.7%), ulcerating (64.3% vs. 63.7%) and intestinal (80.9% vs. 78.4%), with no significant differences between them. The main histopathology was adenocarcinoma with an increase in the signet cell variant (4% to 12.1%, P, 0.03) during period II. Advanced stages III and IV constituted 71.1% and 76.5% of all patients in periods I and II, respectively (P, 0.9). More D2 lymph node dissections and increased use of adjuvant chemo‐radiotherapy and palliative chemotherapy were noted during period II. Median survival time for the entire cohort was 12.3 months (95% CI 9.7–14.4) with a 5‐year overall survival rate of 16.5%. The 5‐year overall survival for periods I and II was 14% and 19% (P, 0.27), respectively. Conclusion: GC in Oman is seen predominantly in elderly males who display predominately distal, ulcerative lesions with an intestinal‐type histology. GC continues to present in advanced stages, with poor prognosis. This fact underscores the need for early diagnosis to achieve a better outcome.

  目的  探讨甲磺酸阿帕替尼治疗二线化疗失败上皮性卵巢癌（epithelial ovarian cancer，EOC）患者的疗效与安全性。  方法  收集2017年9月至2018年11月46例天津医科大学肿瘤医院收治的二线化疗失败的复发性EOC患者的临床资料，分析甲磺酸阿帕替尼的疗效及治疗相关的不良事件，并评估其安全性。  结果  46例患者的中位随访时间为12个月，中位总生存（overall survival，OS）时间为6（2~15）个月。客观缓解率（objective response rate，ORR）为26.1%（12/46），疾病控制率（disease control rate，DCR）为86.9%（40/46）。46例患者中30例（65.2%）出现不良反应，主要为1~2级，最常见的治疗相关不良反应为高血压占39.1%（18/ 46），手足皮肤综合征占30.4%（14/46），仅1例患者出现3级治疗相关性高血压，所有患者的1、2级不良事件均能迅速缓解，且甲磺酸阿帕替尼治疗后患者耐受性良好。  结论  甲磺酸阿帕替尼对于二线化疗失败的EOC患者可能是一种安全且有效的治疗选择，但仍需开展大规模的临床试验进一步研究。
