In case of established cancerous dissemination it is postulated that the sentinel lymph node s is are the target organs primarily reached by metastasizing cancer cells from the tumor. Sentinel node biopsy identifies the first few lymph nodes into which a tumor drains.

In a mouse study he demonstrated the induction of just such an augmented cryoimmunologic response as reflected in increased natural killer cell function an increase in th1 but not th2 type cytokines and an increase in tumor specific t cells in tumor draining lymph nodes.
