The use of immune checkpoint inhibitors (ICIs) in early-stage settings has shown promise but can lead to chronic immune-related toxicities known as delayed immune-related adverse events (DIREs). These events, occurring after immunotherapy cessation, can affect various organ systems. Fatal immune-related adverse events (irAEs) are relatively rare but significant. Diagnostic challenges exist in distinguishing DIREs from disease sequelae. Efforts are needed to develop evidence-based strategies for managing DIREs as long-term survival with ICIs becomes possible. This case study highlights delayed neurological immune-related adverse events (NirAEs) encountered during pembrolizumab treatment, emphasizing the need for accurate diagnosis and prompt management. Reporting practices in immunotherapy trials hinder accurate assessment of DIREs. Close monitoring, accurate diagnosis, and timely corticosteroid administration are vital for effective DIRE management.

Combined blockade of the immune checkpoints PD-1 and CTLA-4 has shown remarkable efficacy in patients with melanoma, renal cell carcinoma, non-small-cell lung cancer and mesothelioma, among other tumor types. However, a proportion of patients suffer from serious immune-related adverse events (irAEs). In severe cases, a reduction of the doses or the complete cessation of the treatment is required, limiting the antitumor efficacy of these treatments.

Immune checkpoint inhibitor (ICI) therapy is a cornerstone treatment for many cancers, but it can induce severe immunotoxicity, including acute interstitial nephritis (AIN). Currently, kidney biopsy is required to differentiate ICI-AIN from other causes of acute kidney injury (AKI). However, this invasive approach can lead to morbidity, delayed glucocorticoid treatment for patients with AIN, and unnecessarily prolonged suspension of ICI therapy in non-AIN patients.

Purpose: To present the case of a young patient with BRAF V600E-mutant cutaneous melanoma who developed bilateral choroidal metastases complicated by neovascular glaucoma (NVG) in both eyes following the interruption of nivolumab therapy.
Methods: A 28-year-old female with primary cutaneous melanoma of the left hand underwent surgical resection and adjuvant nivolumab. Immunotherapy was discontinued due to immune-related acute interstitial nephritis.

Background/objectives: Water-soluble vitamins, comprising the B-complex vitamins and vitamin C, are essential for normal growth, cellular metabolism, and immune function in pediatric populations. Due to limited storage in the body, these vitamins require consistent intake to prevent deficiencies. Pediatric populations, particularly infants and young children, face a heightened risk of both deficiency and, in rare cases, toxicity due to varying dietary intake and increased developmental needs.

: Immune checkpoint inhibitors (ICIs) have revolutionized cancer therapy, but their use is associated with a spectrum of immune-related adverse events (irAEs), including endocrine disorders. This study aims to investigate the incidence, timing, treatment modalities, and impact of ICI-related endocrine side effects in cancer patients. : This retrospective study analyzed 139 cancer patients treated with ICIs between 2016 and 2022.
