In this segment, the presenter describes a personalized immunotherapy approach that harvests a patient’s natural killer (NK) and dendritic cells, expands them ex vivo, and trains them to recognize tumor antigens and peptides. After this preparation, the cells are reinfused into the patient. The speaker shares a compelling case of a man with advanced squamous cell carcinoma of the neck who, after receiving the cell infusion, experienced a warm sensation, rapid tumor shrinkage within hours, and restored ability to eat, illustrating the pivotal role of the immune system in combating this cancer.

Chapters

We take the natural killer cells, dendritic cells, out of the body. We grow them, we expand them, teach them to attack the tumor against damps and antigens and peptides, and then reinfuse them into the body. I just had a patient I spoke to that I hadn't seen in a while and three years ago came to us with a neck cancer like a squamous cell in the neck. Couldn't eat, was wasting away, wasn't sure, and when, as soon as he received his cells, he felt warmth around his neck like a fever. It was like a good feeling. Within four hours started to shrink, and within several I was able to eat again. He shared with me and reminded me of that again. And we've done that with patients where in his case the immune system was such a critical piece to care.
