The main questions it aims to answer are:\n\n1. Investigators plan to correlate circulating tumor cells (CTC), circulating tumor emboli (CTM), and the composition of NK cells in CTM with clinical outcomes and establish their association with patient prognosis.\n2. Investigators plan to understand the composition of NK cells and the immune cell components within CTM, and correlate these findings with treatment efficacy.\n\nPatients with recurrent\u002Fmetastatic head and neck cancer will be included after informed consent and investigators will collect blood samples for analysis from them under the treatment provided by their primary care physicians.",[63,64,65],"Head and Neck Cancers- Squamous Cell","Head and Neck Cancer Metastatic","Recurrent Head and Neck Squamous Cell Carcinoma",[67,68,69,70,71,72,73,74,75],"head and neck cancer","circulating tumor cell","CTC","circulating tumor emboli","CTM","NK cell","nature killer cell","prognosis","INF-gamma","2026-02-22",{"date":78,"type":79},"2026-02-24","ACTUAL",{"date":81,"type":79},"2025-01-01",{"date":83,"type":58},"2027-12-31",{"name":5,"class":6},1]
