Chemotherapeutics are the mainstay of the majority of antitumor treatment strategies. These agents are usually administered at or near maximum tolerated doses resulting in frequent dramatic toxicities that compromise the quality of life and the immune response towards microbial pathogens. A number of observations suggest that low-dose treatment with chemotherapeutics is sometimes equal or even superior to high-dose chemotherapy. The efficacy of low-dose chemotherapy can be at least partly explained by the regulation of the antitumor immune response. The immunomodulatory effects of some chemotherapeutics might be further potentiated by combinations with selected biological response modifiers such as recombinant cytokines (IL-2, TNF, IL-12). The effectiveness of such treatment combinations have already proved effective in preclinical animal models. However, the efficacy in humans is still to be demonstrated in rationally designed clinical trials. 相似文献

BackgroundA previous study has shown that shorter bevacizumab infusions (0.5 mg/kg/min) can be safely administered without increasing the risk of infusion-related hypersensitivity reactions (HSRs). However, the risk of proteinuria and hypertension in patients receiving shorter infusions of bevacizumab is undetermined.Patients and methodsThis was a multicenter, prospective, observational study in patients receiving <10 mg/kg of bevacizumab infused over 0.5 mg/kg/min. Patients were observed until discontinuation of bevacizumab for progression of cancer or toxicity. The incidence of hypertension and proteinuria was compared with a prior cohort of patients who had received standard duration infusions of bevacizumab.ResultsSixty-three patients received a total of 392 doses of shorter bevacizumab infusions. Nineteen (30.2%) patients experienced proteinuria while receiving bevacizumab. Out of 19 patients, 13 had grade 1 and 6 had grade 2 proteinuria. None of the patients experienced grade 3 or 4 proteinuria. Hypertension was reported in 32 (50.8%) patients receiving bevacizumab. Twelve (19%) patients developed grade 3 or greater hypertension on bevacizumab. The incidence of proteinuria and hypertension was 38.3% and 56.6%, respectively, in patients (N = 120, 1347 infusions) receiving standard duration infusions of bevacizumab.ConclusionsShorter bevacizumab infusions (0.5 mg/kg/min) do not increase the risk of proteinuria and hypertension. 相似文献
