“…Two studies in patients with melanoma demonstrated the inability of FDG‐PET/CT to differentiate between patients who had pseudoprogression because of inflammatory infiltrate and those who had actual PD . Cho et al evaluated the ability of FDG‐PET/CT in conjunction with other imaging modalities to predict early response to therapy in patients with advanced melanoma who receive treatment with several checkpoint inhibitors . At each post‐treatment time point, response was assessed based on RECIST 1.1, irRC, Positron Emission Tomography Response Criteria in Solid Tumors (PERCIST 1.0), and European Organization for Research and Treatment of Cancer criteria.…”

Significant advances in the genetic and molecular characterization of cancer have led to the development of effective immunotherapies. These therapeutics help the host immune system recognize cancer as foreign, promote the immune system, and relieve the inhibition that allows growth and spread of tumors. Experience with various immunotherapies, particularly the immunomodulatory monoclonal antibody ipilimumab, has demonstrated that unique patterns of response may be encountered that cannot be adequately captured by traditional response criteria, such as the World Health Organization (WHO) criteria and Response Evaluation Criteria in Solid Tumors (RECIST), which have been used primarily with cytotoxic chemotherapies. In response to these observations, several novel response criteria have been developed to evaluate patients who receive immunotherapy, including immune-related response criteria (irRC), immune-related RECIST (irRECIST), and immune RECIST (iRECIST). These criteria are typically used in conjunction with RECIST version 1.1 in the clinical trial setting, because approval of new therapeutics by the US Food and Drug Administration relies on the responses derived from RECIST version 1.1. Finally, a wide variety of immune-related adverse events may affect patients who receive immunotherapy, many of which can be identified on imaging studies such as computed tomography, magnetic resonance imaging, and 2-deoxy-2-(fluorine-18)fluoro-D-glucose-positron emission tomography/computed tomography. In this review, the authors present the role of imaging in the evaluation of patients treated with immunotherapy, including the background and application of irRC, irRECIST, and iRECIST; the imaging of immune-related adverse events; and future directions in advanced imaging of immunotherapy.

“…Outcomes from these studies indicated that 18 F‐FDG PET/CT scan can provide complementary information to classic anatomic imaging including CT and MR imaging, however, larger cohorts are warranted to validate these findings from studies with small sample size. Of note, it is essential for radiologists to realize that increased 18 F‐FDG uptake is not specific for neoplasms regardless of its high sensitivity, because other pathological processes, including inflammatory reaction, can also show elevated glucose metabolism.…”

“…Of note, it is essential for radiologists to realize that increased 18 F‐FDG uptake is not specific for neoplasms regardless of its high sensitivity, because other pathological processes, including inflammatory reaction, can also show elevated glucose metabolism. In this setting, it is a great challenge for readers to distinguish tumor progression and metastases from inflammation on PET scans . Future efforts are warranted to solve this dilemma in 18 F‐FDG PET/CT.…”

Role of medical imaging for immune checkpoint blockade therapy: From response assessment to prognosis prediction

Immune checkpoint blockade (ICB) represents a promising approach in cancer therapy. Owing to the peculiar biologic mechanisms of anticancer activity, checkpoint blockers are accompanied with distinctive response patterns and toxicity profiles. Medical imaging is the cornerstone for response assessment to immunotherapy and plays a critical role in monitoring of immune‐related adverse events (irAEs). Imaging‐based biomarkers have shown tremendous potential for the prediction of therapeutic efficacies and clinical outcomes in patients treated with checkpoint inhibitors. In this article, the landscape of current response assessment systems for immunotherapy was reviewed with a special focus on the latest advances in the assessment of responses to ICB. Emerging imaging biomarkers were discussed along with the challenges regarding their clinical transformation. In addition, the biological mechanisms and clinical applications of ICB and irAEs were also within the scope of this review.

In vivo molecular imaging is a powerful tool to analyze the human body. Precision medicine is receiving high attention these days, and molecular imaging plays an important role as companion diagnostics in precision medicine. Nuclear imaging with PET or SPECT and optical imaging technologies are used for in vivo molecular imaging. Nuclear imaging is superior for quantitative imaging, and whole-body analysis is possible even for humans. Optical imaging is superior due to its ease of use, and highly targeted specific imaging is possible with activatable agents. However, with optical imaging using fluorescence, it is difficult to obtain a signal from deep tissue and quantitation is difficult due to the attenuation and scattering of the fluorescent signal. Recently, to overcome these issues, optoacoustic imaging has been used in in vivo imaging. In this article, we review in vivo molecular imaging with nuclear and optical imaging and discuss their utility for precision medicine.
