The traditional therapy includes surgery, chemotherapy, and radiotherapy. But the five-year survival of head and neck cancer is 50-60%, which is relatively poor. Thus immunotherapy using targeting agents have been spotlighted in recent years. As preceding research for immunotherapy, the aim of this study is to analysis the immune markers which express in blood and lymph nodes of head and neck cancer. Methods: Blood and lymph node were sampled from patients who underwent surgery for squamous cell carcinoma or a benign tumor in head and neck area. Using flow-cytometry analysis and Milliplexkitยฎ, we compared immune markers in both groups. Results: The expression ratio of CD8 and CD40 in serum was statistically lower in malignant group. IL-6 in plasma was statistically higher in malignant group. Those were same in subgroup analysis between the benign, low-stage, and high-stage group. Analysis of lymph node did not show any significant difference between two groups. But the expression of CD33 in lymph node was lower in extra-capsular spread(ECS) positive group than that in the ECS-negative group. Conclusion: The difference of expression of CD40 and IL-6 in this study implies a possibility of immunotherapy targeting these immune markers in the treatment of head and neck cancer.Introduction 1 Materials & Methods 3 1) Patients 3 2) Collection of samples 4 3) Measurement 4 4) Statistical analysis 5 Results 7 1) Comparison of the distribution of immune cells using blood and lymph node tissue in patients with malignancy or benign tumor 7 2) Comparison of the level of cytokines using plasma in patients with malignancy or benign tumor 9 Discussion 11 Conclusions 17 References 18Maste
