Still early, but different and promising approach to immunotherapy: bacteria based vaccines

[Maxone73]

Ok, in vivo/vitro and not prostate cancer related (for now), but this is a very interesting proof of concept:

"In studies using mouse models of advanced colorectal cancer and melanoma, the bacterial vaccine supercharged the immune system to suppress the growth of -- or in many cases eliminate -- primary and metastatic cancers. All while leaving healthy parts of the body alone."

"The net effect is that the bacterial vaccine is able to control or eliminate the growth of advanced primary or metastatic tumors and extend survival in mouse models," says Jongwon Im, a PhD student at Columbia University who helped lead bacterial engineering aspects of the study.

So, bacteria are particularly unfriendly toward cancer...good to know!
