Autologous tumour cell vaccines vs. dendritic cell vaccines: What’s best, and why?
Understanding the best approach for tumour vaccinations is of growing importance in the personalized cancer immunotherapy field. Current models use a variety of treatments, but two include the use of irradiated autologous tumour cells (TCV), or autologous dendritic cells loaded with tumour associated antigens (DCV). In a randomized trial of metastatic melanoma patients undergoing either TCV or DCV, DCV patient survival was far superior at 43.4 vs 20.5 months. Why was the response more effective when the same antigens were provided to the immune response? Dillman, Robert O., et al. brought some answers in a paper published in the Journal for immunotherapy of cancer in 2018). Looking at the cytokine “milieu” with the Quantibody 200 Biomarker Microarray Service helped the authors in understanding the differences in vaccine responses. [Read more…]
