Tracking Peripheral Memory T Cell Subsets in Advanced Nonsmall Cell Lung Cancer Treated with Hypofractionated Radiotherapy and PD-1 Blockade

Figure 3

Imaging data and changes in immune memory T cell subsets in patients who showed partial response (PR) before and after treatment with HFBT + PD-1 blockade. (a, b) PET-CT fusion images and PET tomography data of a PR patient treated with HFBT + PD-1 blockade showing excellent tumor control. Comparison of peripheral CD4+ (c) and CD8+ (d) memory T cell subsets in PR patients pre- and post-treatment with HFRT + PD-1 blockade. (e) Trends of peripheral memory T cell subsets over 2 years in a patient with long-term PR. PET-CT: positron emission tomography-computed tomography. , , , , and ns, not significant.
