This combination chemotherapy was generally well tolerated and no serious adverse events were noted during or after chemotherapy. Compared to a traditional VAC regimen, oxaliplatin-based chemotherapy significantly improved prognosis over the median follow-up duration of 24 months and improved the negative rate of surgical margin to a greater degree in patients with stage IV limb STS. Importantly, oxaliplatin combination therapy significantly FHPI mouse increased progression free survival over the study period. These results indicate that oxaliplatin-dacarbazine chemotherapy can effectively improve tumor remission in patients with advanced limb STS compared to traditional VAC scheme. Safety of the Oxaliplatin-Dacarbazine Treatment In this study, we used a combination

of oxaliplatin and dacarbazine as neoadjuvant/adjuvant chemotherapy to determine the safety and efficacy of this treatment for advanced limb STS. To our knowledge, this study constitutes the first

report for the use of oxaliplatin in the treatment of advanced STS. Previously, oxaliplatin has been used to treat malignant tumors in the digestive system, ovarian cancer, breast cancer, lymphoma, small cell Tolmetin lung cancer, among others and its safety has been widely confirmed. A phase I and pharmacokinetic study of pemetrexed in combination with oxaliplatin was ever performed to determine the maximum tolerated dose (MTD), and to evaluate safety and pharmacokinetics in patients with metastatic solid tumors. Thirty-six patients with advanced tumors were observed, including 5 patients with sarcomas. This study demonstrated that the combination of pemetrexed plus oxaliplatin is feasible and can be safely administered every 21 days in patients with solid tumors. Toxic effects were predictable, reversible and manageable, with neutropenia being the primary toxicity and no unexpected toxicity observed. The recommended dosage for oxaliplatin was 120 mg/m2 [9]. Dacarbazine is considered a critical chemotherapeutic agent in comprehensive treatment regimes for advanced STSs [10, 11]. Patients in both the experimental and control groups experienced grade 1 to 2 adverse effects, consisting mainly of digestive and blood system toxicity. All patients had mild to moderate peripheral neuropathy, which remitted following the drug treatment, as expected from previous studies.
