The Treatment of Advanced Lung Cancer With Dribbles Antigen by Targeting Activation of Tcells

Summary

Malignant tumor has become the leading cause of death in humans, and the number one killer in malignant tumor is the lung cancer. Intensifying environmental pollution comes with rising of the incidence of lung cancer and the high mortality,what's the worst that the 5-year survival rate is only about 15%, accounting for first place in the malignant tumors, Exploiting for novel antitumor technology and products comes to arrest growing attention of the governments and businesses because of the uneffectively curbing of tumor threat to people's life and health on conventional three treatments (surgery, radiotherapy and chemotherapy). Biological and immunotherapy was voted to one of the ten big breakthrough in 2013 by Science magazine, and considered as a new development direction for cancer treatment in the 21st century. The existing immune treatment mainly includes: adoptive immune therapy, tumor vaccine therapy, immune checkpoint-antibody therapy and other auxiliary therapy, and the adoptive immunotherapy was researched and developeded former in addition the most mature treatment among these therapies. Recently, Dr Hu Hong - Ming's team put forward an innovative cancer treatment strategy: using of autophagy role to capture tumor antigen for preparation of tumor vaccine. In this strategy, the blocking proteasome activity of in vitro cultured tumor cells dealed with Bortezomib (proteasome inhibitors) causes enrichment of short-lived protein (SLiPs) and misfolded proteins (DRiPs) in autophagosome,called DRibbles corpuscle. Tumor vaccine maded from collecting these DRibbles corpuscle preparation as, also known as the DRibble vaccine. At present, clinical research has been carried out about Dribble liver cancer vaccine unit with DC - CIK therapy in liver cancer in the second hospital of Nanjing nearly four years,and more than 300 cases has been completed. Clinical research results show that Dribble vaccine has good security, producing stronger immune response compared with the DC-CIK therapy alone. But it is still no cognization for the efficacy and safety of DC-CIK joint DRibble lung cancer vaccine in China, whether it is better than the current DC - CIK immune therapy, needed for further clinical research and expected to provide a better immune treatment for NSCLC patients.
