Background/Objective: People living with human immunodeficiency virus (PHIV) are at increased risk for malignancies, yet their access to immunotherapy remains limited due to concerns about safety and efficacy. This systematic scoping review evaluates the use of immune checkpoint inhibitors (ICIs) in HIV-associated cancers, analyzing patient outcomes, safety profiles, and the impact on HIV status. Methods: A comprehensive literature search was conducted in databases including PubMed, Scopus, Web of Science (WoS), and Medline, up to January 2025. Studies included assessing the efficacy of ICIs in cancer patients with HIV. The primary outcomes were (a) the efficacy of immune ICIs on prognosis, progression-free survival (PFS), and overall survival (OS). Secondary outcomes were the immune-related adverse events (irAEs) and the survival rate of cancer patients receiving ICIs. Results: A total of 107 cases from 19 studies published between 2011 and 2024 were reviewed. Responses to programmed death 1 (PD-1) inhibitors varied, with 27.1% achieving partial response, 23.36% experiencing stable disease, and 6.54% achieving complete response, while 34.57% had disease progression. Adverse events, including hematologic and endocrine toxicities, were common but mostly manageable. HIV viral loads remained stable in most cases. Conclusions: PD-1 inhibitors demonstrated potential efficacy in HIV-associated malignancies with a safety profile comparable to the general population. However, disease progression remained a concern, highlighting the need for optimized patient selection. Further well-controlled trials are essential to establish treatment guidelines and ensure equitable access to immunotherapy for PHIV. Full article

Background and Objectives: Urothelial bladder carcinoma includes a spectrum of malignant lesions with heterogeneous molecular, biological, and clinical features and a variable risk of progression from non-muscle-invasive bladder cancer (NMIBC) to muscle-invasive disease (MIBC) and ultimately to metastatic urothelial carcinoma (mUC). Sarcopenia, a condition secondary to a catabolic state, is characterized by progressive loss of skeletal muscle mass and function and is highly prevalent across all stages of bladder cancer. This review aims to synthesize current evidence regarding the clinical impact of sarcopenia and its dynamic changes throughout the disease course. Materials and Methods: A narrative literature review was conducted using PubMed, Scopus, and Cochrane databases, incorporating the most relevant published sources. Search terms included “bladder carcinoma”, “sarcopenia”, “body composition”, “NMIBC”, and “MIBC”. Case reports and congress abstracts were excluded. Results: In NMIBC treated with intravesical Bacillus Calmette–Guérin (BCG), sarcopenia has been shown to have a negative predictive value in some studies. Among patients receiving neoadjuvant chemotherapy (NAC) for MIBC, sarcopenia has been associated with increased toxicity, dose reductions, and treatment delays. In the context of radical surgery, sarcopenia correlates with increased postoperative mortality and a higher rate of severe complications. In mUC, low muscle mass is a negative prognostic factor regardless of treatment type and is associated with chemotherapy-related hematologic toxicity, although it does not appear to predict immune-related adverse events (irAEs). Conclusions: Sarcopenia is a highly prevalent and clinically relevant phenotype of urothelial bladder cancer patients, impacting prognosis, treatment response, and chemotherapy toxicity. Incorporating sarcopenia with other relevant components of body composition (BC) and systemic inflammatory markers may facilitate the development of more robust risk scores. Current evidence is primarily limited by the retrospective design of most studies. Future prospective research is needed to clarify the prognostic role of sarcopenia and support its integration into routine clinical decision-making. Full article

Background: Immune checkpoint inhibitors (ICIs) have reshaped the treatment landscape of metastatic melanoma. While combination regimens often demonstrate improved response and survival compared to monotherapy, they are also associated with a higher incidence of immune-related adverse events (irAEs). Understanding the balance between benefit and risk is essential for making informed treatment decisions, especially given the variability in reported outcomes across clinical trials. Methods: We conducted a systematic review and meta-analysis of 14 clinical trials (comprising 22 treatment arms and >5000 patients) comparing ICI monotherapy (nivolumab, ipilimumab, or pembrolizumab) and combination therapy (nivolumab + ipilimumab) in advanced melanoma. Treatment-related outcomes were synthesized using fixed-effects, random-effects, or generalized linear mixed models (GLMMs), depending on study variability. Survival data were extracted from published Kaplan–Meier curves and analyzed using longitudinal GLMMs to capture trends over time. Results: Compared to monotherapy, combination immunotherapy achieved higher clinical benefit, with an overall response of 52.2% (vs. 31.6%), a five-year overall survival of 55.7% (vs. 34.3%), and a five-year progression-free survival of 39.0% (vs. 17.2%). However, this benefit came with a higher risk of toxicity: immune-related adverse events occurred in 93.2% of patients receiving combination therapy versus in 81.9% receiving monotherapy. Differences were consistent across all individual severe toxicities. Conclusions: Combination immunotherapy offers greater long-term clinical benefit than monotherapy in metastatic melanoma but at the cost of increased toxicity. By applying models adapted to study variability, we provide more reliable estimates of treatment efficacy and risk. GLMMs provide the most robust estimates and enable the modeling of survival dynamics over time. These findings support evidence-based decision-making and highlight the value of model-informed meta-analysis in oncology. Full article

Background: Immune checkpoint inhibitors (ICIs) transformed cancer treatment, producing significant survival benefits. However, ICIs can trigger toxicities called immune-related adverse events (irAEs), including inflammatory arthritis (IA) and polymyalgia rheumatica (PMR)-like syndromes. Our study aimed to systematically further characterize musculoskeletal ultrasound (MSKUS) findings in patients with ICI-IA and ICI-PMR, collectively referred to as “MSK-irAEs”, and explore the role of US in guiding treatment. Methods: The authors conducted a comprehensive chart review for patients receiving ICIs undergoing MSKUS at our center’s rheumatology clinics. US examinations were performed and reviewed by two MSKUS-certified rheumatologists. Descriptive statistics were performed to summarize demographic, clinical, and treatment-related variables. US findings were categorized with a novel scoring system: 0—no signs of inflammatory arthropathy or tendinopathy, 1—potential signs of inflammation (grayscale ≥ 2, effusion without power Doppler, synovial hypertrophy in the joint), and 2—active inflammation in joints and/or tendons (characterized by power Doppler) and signs of inflammation. Results: Twenty-three patients were included. The median age was 63 years, 52% were male, and 87% were White. Melanoma was the most common cancer (48%). MSK-irAEs were diagnosed in nineteen (83%), with MSKUS showing inflammation in seventeen (74%). Sixteen (70%) received escalation in MSK-irAE treatment after MSKUS. Four (17%) had erosive disease due to MSK-irAEs, while one had erosive osteoarthritis. Individuals with inflammatory erosive changes experienced prolonged intervals between symptom onset and MSKUS, ranging from 17 to 82 months, suggesting that erosions may reflect chronic, under-recognized inflammation. On MSK-irAE therapy, nine (47%) experienced symptomatic improvement, five (26%) achieved resolution, and in four (21%) cases, it was too early to assess the response. MSKUS detected other causes of MSK symptoms besides MSK-irAEs in several patients, allowing ICI resumption in one. Conclusions: Our study highlights the clinical utility of MSKUS not only as a diagnostic tool but also to guide therapeutic decision-making. Full article

Background: Immune checkpoint inhibitors (ICIs) have transformed cancer treatment, yet severe immune-related adverse events (irAEs) often necessitate immunotherapy discontinuation and cause life-threatening complications. Circulating plasma proteins, dynamically accessible and functionally linked to immunity, may predict and offer novel targets for irAEs. Methods: Leveraging multi-omics integration, we conducted bidirectional two-sample Mendelian randomization (MR) using protein quantitative trait loci (pQTLs) from 4998 plasma proteins and genome-wide association data of irAE phenotypes. A causal inference framework combining colocalization analysis, multivariable MR (MVMR) adjusting for body mass index (BMI) confounding, and mediation MR elucidated BMI-independent pathways. Systems biology approaches including tissue-specific expression profiling, pathway enrichment, and protein interaction network analysis revealed spatial and functional drivers of irAE pathogenesis. Results: Proteome-wide MR mapping identified eight plasma proteins (CCL20, CSF1, CXCL9, CD40, TGFβ1, CLSTN2, TNFSF12, TGFα) causally associated with all-grade irAEs, and five (CCL20, CCL25, CXCL10, ADA, TGFα) with high-grade irAEs. Colocalization prioritized CD40/TNFSF12 (all-grade) and ADA/CCL25 (high-grade) as therapeutic targets (PPH4 > 0.7). CXCL9/TNFSF12 (all-grade) and CCL25 (high-grade) exerted BMI-independent effects, suggesting intrinsic immune dysregulation mechanisms. Tissue-specific gene expression patterns, CSF1, TGFβ1 in lung, TNFSF12 in the ileum may explain organ-specific irAE vulnerabilities. High-grade irAEs correlated with compartmentalized immune dysregulation and IL-17/immunodeficiency pathway activation. Conclusions: This study establishes the causal atlas of plasma proteins in irAE pathogenesis, bridging biomarker discovery with actionable therapeutic targets. These advances align with next-generation immunotherapy goals: maximizing efficacy while taming the immune storm. Full article

Background/Objectives: The physiological activation of cytotoxic CD8^pos T cells (CTLs) relies on the engagement of the TCR/CD3 complex with cognate peptide-HLA class I (pHLA-I) on target cells, triggering cell lysis with appropriate cytokine release and minimized off-target toxicity. In contrast, current immunotherapies for CD19-expressing hematological malignancies, such as chimeric antigen receptor (CAR) T cells and bispecific T cell engagers (BiTEs), bypass TCR/pHLA interactions, resulting in CTL hyperactivation and excessive cytokine release, which frequently cause severe immune-related adverse events (irAEs). Thus, there is a pressing need for T cell-based therapies that preserve physiological activation while maintaining antitumor efficacy. Methods: To address this, we developed CD19-ReTARG^TPR, a novel fusion protein consisting of the immunodominant cytomegalovirus (CMV) pp65-derived peptide TPRVTGGAM (TPR) covalently presented by a soluble HLA-B*07:02/β2-microglobulin complex fused to a high-affinity CD19-targeting Fab antibody fragment. The treatment of CD19-expressing cancer cells with CD19-ReTARG^TPR makes them recognizable for pre-existing anti-CMV_pp65 CTLs via physiological TCR-pHLA engagement. Results: Our preclinical data demonstrate that CD19-ReTARG^TPR efficiently redirects anti-CMV CTLs to eliminate CD19-expressing cancer cells, including both established cell lines and primary chronic lymphocytic leukemia (CLL) cells. Unlike CD19-directed CAR T cells or the CD19/CD3 BiTE blinatumomab, CD19-ReTARG^TPR mediated robust cytotoxic activity without triggering supraphysiological cytokine release. Importantly, this approach retained efficacy even against cancer cells with low CD19 expression. Conclusions: In summary, we provide a robust proof-of-concept study and show that CD19-ReTARG^TPR offers a promising alternative strategy for T cell redirection, enabling the selective and effective killing of CD19-expressing malignancies while minimizing cytokine-driven toxicities through physiological CTL activation pathways.

Background/Objectives: Nivolumab is a key therapy for advanced-stage melanoma; however, limited data are available from Asian populations comparing the efficacy and side effects of four dosing regimens: 3 mg/kg every 2 weeks (3mg/kgQ2W), 2 mg/kg every 3 weeks (2mg/kgQ3W), 240 mg every 2 weeks (240mgQ2W), and 480 mg every 4 weeks (480mgQ4W). This retrospective study evaluated Japanese patients with advanced melanoma treated with various nivolumab regimens to assess the impact of dosing interval and dosage on treatment efficacy and immune-related adverse events (irAEs). Methods: We reviewed the records of 153 participants with stage IV melanoma who received nivolumab monotherapy between February 2012 and December 2024 at Shizuoka Cancer Center. Patients were categorized by nivolumab regimen, dosing interval, and dose per body weight. We then compared treatment efficacy and incidence of irAEs across groups. Results: No significant differences were observed in objective response rate (ORR), progression-free survival (PFS), overall survival (OS), or irAE incidence between the 240mgQ2W and 480mgQ4W groups. Similar results were observed in the 3mg/kgQ2W and 2mg/kgQ3W groups. However, participants who received nivolumab within 3 weeks exhibited a significantly higher ORR than those who received nivolumab more than 3 weeks. No significant differences were found in PFS or OS. Conclusions: The administration of nivolumab at shorter intervals may provide short-term benefits in Japanese patients with advanced melanoma. However, long-term efficacy and side effects did not differ significantly across the studied nivolumab regimens. Full article

Background: Melanoma management has been revolutionized by the use of immune checkpoint inhibitors (ICIs). However, ICIs are associated with immune-related adverse events (irAEs), including rhinosinusitis, which remains underexplored. This study evaluated the incidence, characteristics, management, and prognostic implications of rhinosinusitis in patients with melanoma under ICIs. Methods: A retrospective analysis was conducted on adult patients with melanoma treated with ICIs. Demographic, clinical, laboratory, treatment, and survival data were collected. Rhinosinusitis was defined radiographically and graded using the Harvard scoring system. Associations between rhinosinusitis and survival outcomes were analyzed. Results: Among 304 patients, 64 (21.1%) developed imaging-confirmed rhinosinusitis during ICI treatment, with 9.4% symptomatic cases. Rhinosinusitis was the sole irAE in 11.8% of patients, and 9.2% experienced it alongside other irAEs. A significant correlation with eosinophilia was observed: 39.6% of eosinophilic patients developed rhinosinusitis versus 17.1% without eosinophilia (p < 0.001). Most cases occurred during the first ICI line (86.4%), particularly with nivolumab monotherapy (32.8%). Importantly, in metastatic melanoma, rhinosinusitis was associated with significantly longer overall survival since ICI initiation (OS_ICI) compared to patients without rhinosinusitis (33.3 vs. 15.4 months, p = 0.025). No survival benefit was observed in the adjuvant setting. The condition was predominantly aseptic, and corticosteroids were used in 7.8%. Conclusions: This study highlights rhinosinusitis as an irAE associated with improved OS in metastatic melanoma. Further research is required to elucidate the underlying mechanisms and assess the resolution of rhinosinusitis after ICI discontinuation. Additionally, rhinosinusitis may serve as a marker of favorable prognosis in metastatic melanoma patients receiving ICIs. Full article

Background/Objectives: Non-small cell lung cancer (NSCLC) accounts for approximately 85% of lung cancer cases, with an increasing incidence in patients over 65 years. Although immune-checkpoint inhibitors (ICIs) have transformed the treatment landscape, elderly patients remain underrepresented in pivotal clinical trials, highlighting the need for real-world evidence on their efficacy and tolerability in this population. Methods: We conducted a multicenter, retrospective study of advanced NSCLC patients treated with ICI alone or in combination with chemotherapy between April 2017 and December 2023. Patients were categorized into three age groups: ≤65 (younger group, YG), 66–79 (older group, OG), and ≥80 years (advanced older group, AOG). Efficacy and safety outcomes were compared across groups. Results: Among 452 patients, 221 (48.9%) were in the OG and 36 (8%) in the AOG. Median progression-free survival (PFS) was similar across groups: 8.3 months (YG), 8.4 months (OG; p = 0.872 vs. YG), and 10.5 months (AOG; p = 0.628 vs. YG). Median overall survival (OS) showed a non-significant trend favoring younger patients: 15.1 months (YG), 10.3 months (OG; p = 0.076 vs. YG), and 12.5 months (AOG; p = 0.070 vs. YG). Grade ≥ 3 immune-related adverse events (irAEs) occurred in 9.7% (YG), 5.9% (OG), and 8.3% (AOG). In patients ≥ 66 years, irAEs were associated with longer PFS (18.1 vs. 6 months; p < 0.001). Conclusions: ICIs demonstrated comparable PFS and OS across age groups, including patients aged ≥ 80 years. Chronological age did not increase irAE incidence. The development of irAEs may serve as a favorable prognostic factor in elderly patients. Full article

Background and Clinical Significance: Non-small-cell lung cancer (NSCLC) with EGFR mutations, particularly de novo compound mutations such as exon 19 deletions (Ex19del) with T790M substitutions, present a significant clinical challenge due to resistance to many treatments. While treating these patients, the administration of osimertinib, a third-generation EGFR inhibitor, after immunotherapy can lead to unique immune-related adverse events (irAEs), such as pneumonitis and, rarely, hepatitis. Case Presentation: A 36-year-old Filipino woman presented with metastatic NSCLC harboring de novo Ex19del and T790M mutations. Despite initial therapy with carboplatin and paclitaxel, followed by chemoimmunotherapy, the patient’s disease progressed. She subsequently developed severe hepatitis from osimertinib after her prior immunotherapy with pembrolizumab. After the hepatitis resolved with high-dose steroids, osimertinib was switched to afatinib, but her disease rapidly progressed with new metastases. A second attempt at osimertinib rechallenge, with concomitant prednisone, resulted in substantial disease control, including improved leptomeningeal disease (LMD) and no recurrence of hepatitis. Conclusions: This case underscores the feasibility of rechallenging with osimertinib in patients who experience adverse events such as hepatotoxicity, provided that appropriate management strategies, such as steroid therapy, are employed. The successful rechallenge in this case highlights the potential of osimertinib as a viable option in advanced EGFR-mutant NSCLC, even after prior treatment-related complications. Full article

Background: The advent of immunotherapy has revolutionised cancer treatment by harnessing the immune system to target tumour cells. However, there is increasing awareness of immunotherapy-related adverse events, which can be severe and even fatal. While system-specific immune-related adverse events (ir-AEs) are well documented, growing evidence suggests the existence of overlap syndromes—distinct clusters of immune-mediated complications. One such syndrome is the overlap of myasthenia gravis, myositis and myocarditis, collectively known as Triple M (3M) syndrome. This syndrome is complex, varying in presentation and severity, with in-hospital mortality rates approaching 40%. Whilst there is consensus on the management of system-specific complications, there is no consensus guidance for the management of these overlap syndromes. Methods: In this paper, we conduct a review of the literature, analysing reported cases of 3M syndrome, focusing on treatment approaches and patient outcomes at an individual level. Conclusions: This review highlights the complexity of diagnosing and managing 3M syndrome due to inconsistent reporting, lack of standardised criteria for diagnosis, and treatment variability. While evidence remains limited, we offer broad clinical recommendations and underscore the urgent need for consensus definitions, prospective data collection, and structured treatment guidance.

Background/Objectives: Immune-related adverse events (irAEs) triggered by immune checkpoint inhibitor therapy (ICI) have been paradoxically associated with both significant morbidity and improved cancer outcomes. While predictive markers for irAEs have been studied in the PD-1 blockade, less is known for their role in CTLA-4 inhibition. This study aims to fill this gap by evaluating NLR and irAE incidence in a CTLA-4-treated population. Methods: This study is a single-center retrospective cohort study investigating 111 patients treated with CTLA-4 inhibition (ipilimumab) to assess associations for baseline low NLR values with cancer outcomes and irAE type and incidence. Patient charts were manually reviewed by a single physician, and unclear clinical events were assessed by a second physician reviewer. Results: In this cohort, the occurrence of more than one irAE presentation was associated with an improved cancer outcome, OR 1.48 (1.02, 2.15). When stratified by organ-specific manifestation, only endocrinologic irAEs were associated with improved cancer outcome, OR 2.82 (1.19, 6.67). A low baseline NLR was statistically significantly associated with an increased incidence of irAEs of any type, OR 4.34 (1.73, 10.9). Conclusions: These data show that irAE occurrence in cancer patients treated with CTLA-4 inhibition is associated with improved cancer outcomes, similar to that previously seen with PD-1 inhibition. It also suggests that the NLR may serve as a practical peripheral biomarker to predict both cancer response and odds of irAEs in patients treated with CTLA-4 inhibition. This low-cost and widely available tool could provide additional information for modeling cancer outcomes. Full article

Background/Objectives: Immune-related cutaneous adverse events (ircAEs) are common complications of cancer immunotherapy and provide insight into immune-related adverse events (irAEs) more broadly. To enhance our molecular understanding, we characterized ircAEs resulting from single-agent (PD1) and combined immunotherapy regimens (P+C). Clinically, maculopapular rash (MPR) and toxic epidermal necrolysis (TEN) resemble ircAEs, providing a valuable basis for investigations. Methods: To investigate the transcriptome and immune infiltrates in ircAEs, we conducted transcriptomic analyses and multiplexed immunohistochemistry on skin biopsies from patients receiving PD1 and P+C, as well as those with MPR, TEN, and healthy controls. Results: Principal component analysis revealed distinct transcriptomic clustering between ircAEs, MPR, and TEN. Specifically, PD1 ircAEs exhibited a gene expression profile similar to TEN, with upregulation of Type-I-response-related genes (e.g., CXCL9 Log2FC 5.34, p < 0.0001, CXCL10 Log2FC 6.03, p < 0.0001), while P+C ircAEs more closely resembled MPR. Immune infiltrates differed significantly between all groups (p = 0.002 by PERMANOVA for all groups). CD4 T-cells were abundant in the dermis of ircAEs from any type of immunotherapy. However, PD1 stained positive in 1.07% of CD4 cells with PD1 monotherapy, compared to 0.3%, 0.4%, and 0.08% in P+C, MPR, and TEN, respectively. Conclusions: This study identified distinct molecular and cellular signatures in ircAEs depending on the type of immune checkpoint blockade. aPD1-associated ircAEs share similarities with the cytotoxic profile of TEN, while P+C more closely mirrored MPR. These findings support the need for tailored management strategies for ircAEs, emphasizing personalized therapeutic approaches to minimize treatment interruptions while preserving the efficacy of cancer immunotherapy.

Background: Increasing evidence suggests that the immunogenicity of COVID-19 mRNA vaccines might influence the efficacy of immune checkpoint inhibitors (ICIs). Current studies have not considered the impact of additional vaccinations, which are now recommended as a preventive strategy against SARS-CoV-2 infection for cancer patients receiving active treatments. Consequently, we leveraged the prospective monitoring from the Vax-On-Third study to explore whether periodic mRNA vaccine boosters administered around the start of ICIs could influence the rates of immune-related adverse events (irAEs) and survival outcomes in patients with advanced non-small cell lung cancer (NSCLC). Methods: Our study included patients with a histological diagnosis of metastatic NSCLC and available PD-L1 tumor proportion score (TPS), who had undergone at least two cycles of upfront treatment with pembrolizumab, cemiplimab, or their combination with platinum-based chemotherapy. Patients who received any additional mRNA-based vaccine doses within 60 days before to 30 days after starting ICIs accounted for the exposed cohort. Those who declined further boosters formed the reference cohort. We analyzed differences in irAE frequencies, progression-free survival (PFS), and overall survival (OS) using univariate and multivariate analyses. Results: Between 27 November 2021 and 31 March 2024, we enrolled 226 eligible patients. The exposed cohort consisted of 112 patients who had received either a third or fourth dose of tozinameran or a bivalent booster. Based on PD-L1 expression levels, 93 (41%) and 133 (59%) patients received single-agent ICIs (PD-L1 TPS ≥ 50%) or combination regimens (PD-L1 TPS < 50%), respectively. Propensity-score matching using comprehensive criteria resulted in two cohorts of 102 patients each, with an optimal balance of prognostic factors. A thorough analysis of any grade irAEs showed no significant differences between the cohorts. A longitudinal survival assessment with a median follow-up of 22.8 (95% CI 19.2–26.0) months showed no difference between the cohorts. The median PFS for the reference and exposed cohorts was 7.5 (95% CI 5.9–9.1) and 8.2 (95% CI 6.2–10.2) months, respectively (p = 0.408; HR 0.88 [95% CI 0.66–1.18]). The median OS for the reference and exposed cohorts was 10.5 (95% CI 7.9–13.0) and 13.8 (95% CI 12.0–15.5) months, respectively (p = 0.170; HR 0.81 [95% CI 0.59–1.09]). Multivariate analysis confirmed that receiving additional mRNA vaccine boosters did not significantly affect the risk of disease progression or mortality. Univariate analysis within the subgroup of patients with high PD-L1 TPS who received single-agent ICIs showed a significant OS advantage for patients in the exposed cohort (9.7 [95% CI 8.1–11.2] vs. 18.6 [95% CI 13.5–23.6] months; p = 0.034; HR 0.59 [95% CI 0.36–0.96]). Conclusion: After optimally balancing prognostic factors, regular mRNA vaccine boosters at the onset of ICIs did not impact the safety and survival of patients with advanced NSCLC. The improved outcome observed in patients with high PD-L1 expression levels aligns with previous findings and warrants further investigation. Full article

Background/Objectives: The increasing use of immune checkpoint inhibitors (ICIs) in cancer treatment has led to a rise in immune-related adverse events (irAEs), including pancreatic injury. While current guidelines suggest that baseline monitoring of amylase and lipase levels is not necessary, it remains common in clinical settings, leading to confusion regarding their interpretation and management. This practice may lead to confusion, especially when patients exhibit isolated mild elevations of amylase and lipase, which may not always correlate with clinical pancreatitis. In contrast, significant elevations in these enzymes warrant further investigation, including imaging to assess the presence of pancreatitis. Methods: This review aims to provide a clearer framework for clinicians in managing ICI-induced pancreatic injury, promoting consistency in practice, and improving patient outcomes by reducing unnecessary interruptions to ICI therapy. Results: It is critical to distinguish between the severity of pancreatitis to guide management. Conclusions: Considering the expected rise in the use of immune ICIs, it is crucial to increase awareness about the potential for pancreatic injury associated with these treatments. Full article
