Tumor metabolic features identified by FDG PET correlates with gene networks of immune cell microenvironment in head and neck cancer
J Nucl Med 2018 59(1):31–37. Abstract The importance of 18F-FDG PET in imaging head and neck squamous cell carcinoma (HNSCC) has grown in recent decades. Because PET has prognostic values, and provid…

Immune landscape of papillary thyroid cancer and immunotherapeutic implications
Endocr Relat Cancer 2018 25(5):523–531. Abstract Although papillary thyroid cancer (PTC) is curable with excellent survival rate, patients with dedifferentiated PTC suffer the recurrence or death. As…

Differences in Tumor Immune Microenvironment in Metastatic Sites of Breast Cancer
Front Oncol. 2021;11:649004. Abstract Introduction: Tumor immune microenvironment (TIME) promotes immune escape, allowing for tumor progression and metastasis. In spite of the current evidence of the…
