Using these lymph nodes as a source of dendritic cells and killer cells, we can eradicate the heterogeneous tumor cells disseminating throughout the body carrying a wide variety of antigens.
112 An alternative explanation may be that cell dissemination is a "normal" cellular process in that even normal cells disseminate at a certain rate.
This may indicate that surgical manipulation of the primary tumours in these individuals has resulted in dissemination of tumour cells into the circulation but the clinical relevance of cells disseminated by surgery is a subject of debate.
As a result, it has been suggested that tumor cells disseminate in an early genomic state and that they acquire genomic alterations after dissemination independent form the primary tumor [ 35].

Moreover, it has been successfully verified that the established strategy could directly identify tumor cells disseminated from various primary sites in multiple types of clinical body fluid samples.
Targeted therapeutics are designed to focus on actionable mutations detected in a biopsy of the primary tumor, but these "actionable" mutations may no longer drive disease progression once tumor cells disseminate from the primary carcinoma and undergo unique genomic changes.
Circulating tumor cells (CTCs) are cancer cells shed from primary or metastatic solid tumors into peripheral blood [1], whereas disseminated tumor cells (DTCs) are neoplastic cells disseminated into biofluid, including bone marrow, ascites, pleural effusion, cerebrospinal fluid (CSF), and urine, etc. [2].
They arise from enterochromaffin cells, which are sparse neuroendocrine cells disseminated throughout the GI tract [1], [2], [3].
These data show that following nasal immunization with OVA and CpG, priming of T lymphocytes occurs in the draining lymph nodes and then activated cells disseminate towards non-draining lymphoid compartments.
