CD70‐targeted immuno‐PET/CT, as a novel noninvasive functional molecular imaging technique, has potential applications in RCC and other CD70‐high‐expressing tumours, including precise detection of early micrometastases, monitoring postoperative recurrence and metastasis, screening patients suitable for CD70‐targeted therapy and optimizing individualized treatment strategies, dynamic monitoring of disease progression and efficacy evaluation, and guiding the development of targeted drugs.154. Here, CD70 is linked to neoplasm.
