    • The present invention provides a method of making a proteinase-engineered cancer vaccine for treating a cancer patient, especially for cancer patient at advanced/metastatic stage. The cancer vaccine comprises dead cancer cells with unbroken plasma membrane wherein the extracellular proteins and extracellular portion of membrane proteins are cleaved by proteinase digestion. The cancer vaccine may be derived from cancer cell lines or patients' cancer cells. The present invention provides a method of treating a cancer patient by administrating an effective amount of the cancer vaccine to the patient. In a clinical trial with 35 cancer patients, the cancer vaccine therapy brings cancer-free lives (no detectable tumor, micro tumor or cancer cells after treatment) back to 40% of these patients. The cancer vaccine therapy for the first time brings the promise of cure to this deadly disease. The present invention further provides a method of obtaining cancer-specific immune components from blood of individuals treated with the cancer vaccine.
    • 本发明提供了一种制备用于治疗癌症患者的蛋白酶工程化癌症疫苗的方法,特别是对于晚期/转移期的癌症患者。 癌症疫苗包括具有不间断质膜的死亡癌细胞,其中细胞外蛋白质和膜蛋白质的细胞外部分被蛋白酶消化切割。 癌症疫苗可以衍生自癌细胞系或患者的癌细胞。 本发明提供了通过向患者施用有效量的癌症疫苗来治疗癌症患者的方法。 在35名癌症患者的临床试验中,癌症疫苗治疗将无癌生命(治疗后无可检测的肿瘤,微型肿瘤或癌细胞)带回到这些患者的40%。 癌症疫苗治疗第一次带来了治愈这种致命疾病的希望。 本发明还提供从用癌症疫苗治疗的个体的血液中获得癌症特异性免疫成分的方法。
