Dissecting Immunotherapy Strategies for Small Cell Lung Cancer: Antibodies, Ionizing Radiation and CAR-T.

Small cell lung cancer (SCLC) is a highly aggressive malignancy that accounts for about 14% of all lung cancers. Platinum-based chemotherapy has been the only available treatment for a long time, until the introduction of immune checkpoint inhibitors (ICIs) recently changed first-line standard of care and shed light on the pivotal role of the immune system. Despite improved survival in a subset of patients, a lot of them still do not benefit from first-line chemo-immunotherapy, and several studies are investigating whether different combination strategies (with both systemic and local treatments, such as radiotherapy) may improve patient outcomes. Moreover, research of biomarkers that may be used to predict patients' outcomes is ongoing. In addition to ICIs, immunotherapy offers other different strategies, including naked monoclonal antibodies targeting tumor associated antigens, conjugated antibody, bispecific antibodies and cellular therapies. In this review, we summarize the main evidence available about the use of immunotherapy in SCLC, the rationale behind combination strategies and the studies that are currently ongoing in this setting, in order to give the reader a clear and complete view of this rapidly expanding topic.

Thyroid function impairment after chemo-immunotherapy for advanced NSCLC: a single institutional retrospective report.

Introduction: Aims of the study were to explore outcomes and toxicities of chemotherapy-immunotherapy (CT-IT) for patients (pts) with metastatic nonsquamous non-small-cell lung cancer (mNSCLC) in a real-world population. Materials & methods: Clinical data of 26 pts with mNSCLC treated with CT-IT at our institution from January 2020 to January 2021 were collected retrospectively. Results: Median follow-up time was 7.7 months. Median progression-free survival was 9.5 months. The most frequent immune-related adverse event was thyroid dysfunction (ThD): 30.7%. Conclusion: There was a higher rate of ThD in this study population compared with the literature, with a possible correlation with clinical outcomes.

Aims of the study were to explore outcomes and toxicities of chemotherapy-immunotherapy (CT-IT) for patients (pts) with metastatic nonsquamous NSCLC (mNSCLC) in a real practice experience, because practice experience not always could be the same of experimental experience. We collected clinical data of 26 pts with mNSCLC, treated with CT-IT at our Institution from January 2020 to January 2021. We observed efficacy and tolerability of treatment were similar to known data, except for thyroid disfunctions (ThD) that was more frequent in our experience. This collateral effect was not cause of treatment interruption, indeed the pts with this manifestation would seem responder better to this therapy. However, we need more time and kind of studies for confirm this observation.
