The primary quality 3 AEs had been hypertension (6.5%), hands foot skin response (6.5%), and diarrhea (3.2%). To conclude, apatinib demonstrated appealing efficiency and appropriate basic safety profile in repeated or metastatic sarcoma, giving rationale clinical evidence to conduct clinical trials. 4.35 [95% CI, 2.22C5.58] months; P = 0.3170) and OS (8.17 [95% CI, 1.56Cnot estimated] months 11.22 [95% CI, 6.64C18.72] months; P = 0.9219) (Fig.?3).

Security Nine (29.0%) patients required short term treatment discontinuation and 7 (22.6%) patients required dose reduction for toxicity management. The median duration of exposure was 2.52 (interquartile range [IQR], 1.06C5.24) months, and mean dosage per day was 372.9 68.4 mg/d. The median relative dose intensity was 98.4% (IQR, 82.4%C100.0%). All of the 31 patients treated with apatinib were assessable for security. Adverse events (AEs) occurred in 25 (80.6%) patients (Table?3). The most common toxicities included fatigue (n = 17, 54.8%), hypertension (n = 14, 45.2%), hand foot skin reaction (n = 12, 38.7%), and nausea (n = 12, 38.7%). Most of the AEs were at grade 1 or 2 2. The grade 3 AEs were hypertension (n = 2, 6.5%), hand foot skin reaction (n = 2, 6.5%), and diarrhea (n = 1, 3.2%). No grade 4 AE or drug-related death occurred. Table 3.

To further evaluate the response to apatinib in sarcomas and add clinical evidences for conducting clinical trials, we retrospectively examined the clinical data of apatinib-treated sarcomas patients in a relatively larger population. The results showed that this CBR was as high as 75.0%, and the median PFS and OS were 4.25 and 9.43 months. Different histological subtype distribution between our and Li 3.79 months),18 suggesting that leiomyosarcoma is usually sensitive to pazopanib and sorafenib. For apatinib, however, challenge remains in patient selection. Apart from monotherapy, combination with chemotherapy might be a treatment strategy, especially for patients who experienced apatinib progression. For instance, apatinib plus paclitaxel bring a PR response in a case with advanced pancreatic liposarcoma.31 In terms of AEs, the most common toxicities included fatigue, hypertension and hand foot skin reaction that were common AEs of anti-angiogenic brokers including apatinib. It has been hypothesized that decrease in nitric oxide (NO) bioavailability is usually associated with the occurrence of hypertension, as the VEGF-mediated expression increase and activation of endothelial NO synthase could be suppressed during anti-angiogenesis therapy.32 Nevertheless, this hypothesis is not well accepted due to the contrary results of experimental and clinical studies. Activation of the endothelin-1 (ET-1) axis may be the key contributor to the mean blood pressure rise during treatment,33 with the underlying mechanism to be investigated. Although the incidence rate of AEs was 80.6%, most of them were at grade 1 and 2 and could be well-controlled by dose reduction, interrupted and/or symptomatic treatment. In conclusion, our study exhibited that apatinib experienced good efficacy and was well tolerated in advanced sarcomas, standing for another feasible option for advanced sarcomas, especially in China. The current study is limited by its retrospective nature, single center, small sample size, and lack of controls. Hence, a prospective, multicenter, randomised,.During therapy, 9 (29.0%) patients required dose interruption and 7 (22.6%) needed dose reduction, and the mean dosage of apatinib was 372.9 68.4 mg/day.
