Objective: Exploring the effects of radiotherapy volume and different radiotherapy techniques on the distribution of lymphocytes and their subsets in chest tumors. Method: Select patients with chest malignant tumors undergoing radiotherapy in our department, measure the volume of the target area, calculate the difference in lymphocytes before and after radiotherapy (ΔLym), and conduct correlation analysis. Compare the distribution of Lym and its subgroups after treatment between photon radiotherapy group and proton radiotherapy group. Result: There is no significant correlation observed between ΔLym and target volume through scatter plot analysis. Pearson correlation analysis r = 0.079, P = 0.672. There was a significant difference in the total number of Lym between the proton radiotherapy group and the photon radiotherapy group after radiotherapy (P = 0.04), with the proton radiotherapy group having a higher Lym count than the photon radiotherapy group. There was no difference in the number of CD3+ T cells, CD19+ B cells, CD8 inhibitory/cytotoxic T cells, CD4 helper/inducible T cells, and CD16+ CD56 NK cells. Conclusion: There is no significant correlation between the volume of the radiotherapy target area and changes in Lym, while proton radiotherapy can reduce lymphocyte depletion. %K 淋巴细胞， %K 质子治疗， %K 调强放疗， %K 适形放疗， %K 计划靶区体积
