Histological Characteristics and Management of Hepatitis on Immune Checkpoint Inhibitors: A Retrospective Descriptive Study.

ABSTRACT:

Background and aims

the side effects of immune checkpoint inhibitors (ICI) pose a problem for the clinical management of cancer patients. There is a lack of knowledge of the value of liver biopsy in patients with ICI-related drug-induced liver injury (ICI-DILI). The aim of this study was to explore the impact of liver biopsy on clinical management and response to corticosteroids, according to histological findings.

Methods

We conducted a retrospective, single-center study to evaluate the biochemical, histological and clinical data of 35 patients with ICI-DILI between 2015 and 2021 in a university hospital in France.

Results

Of the 35 patients with ICI-DILI (median [interquartile range] age 62 [48-73] years, 40% males) studied, 20 underwent a liver biopsy. There was no difference in the management of ICI-DILI according to liver biopsy in terms of ICI withdrawal, reduction or rechallenge. According to the histological profile, patients with toxic and granulomatous profiles had a better response to corticosteroids, while patients with cholangitic lesions had the worst response.

Conclusion

In ICI-DILI, liver biopsy must not delay patient care but may be useful in identifying patients with a cholangitic profile who have a poorer response to corticosteroids.

Project description:The present study aimed to evaluate the incidence, characteristics and management of hepatic immune-related adverse events (irAEs) in patients with advanced or metastatic urothelial carcinoma (UC) and renal cell carcinoma (RCC) receiving immune checkpoint inhibitors (ICIs). Data regarding the demographics, ICI regimens and hepatic irAEs from 213 patients with metastatic UC or metastatic RCC receiving ICIs between February 2018 and September 2023 at three tertiary medical centers (Inje University Busan Paik Hospital, Busan, South Korea; Dongnam Institute of Radiological and Medical Sciences Cancer Center, Busan, South Korea; Pusan National University Hospital, Busan, South Korea) in South Korea were collected and retrospectively analyzed. Hepatic irAEs were graded using the Common Terminology Criteria for Adverse Events version 5.0 and classified based on R value patterns. Among the 213 patients evaluated, 76 (35.6%) experienced at least one irAE, whereas 48 (22.5%) developed hepatic irAEs. The median onset time for hepatic irAEs was 6.5 weeks, with incidence rates being higher with combination therapies than with monotherapies (31.8 vs. 18.3%; P=0.014). Furthermore, 72.9 and 27.1% of the patients had grade 1-2 and 3-4 hepatic irAEs, respectively. The patterns of liver toxicity included cholestatic (35.4%), mixed (35.4%) and hepatocellular (29.2%). All patients with grade 1-2 hepatic irAE recovered with supportive treatment without ICI discontinuation or corticosteroids use. Among the 13 patients with grade ≥3 hepatic irAEs, 12 recovered with high-dose corticosteroids, while 1 died due to fulminant hepatitis. Hepatic irAEs are common in patients with advanced and metastatic urologic cancers who are treated with ICIs, particularly with combination therapies. Most cases have low-grade irAE that are manageable without ICI discontinuation; however, severe cases require prompt recognition and treatment with corticosteroids. These findings emphasize the importance of regular liver function monitoring and appropriate management strategies for hepatic irAEs in patients with urologic cancer receiving ICI therapy.

Project description:BackgroundThe optimal timing to discontinue immune checkpoint inhibitor (ICI) therapy in hepatocellular carcinoma (HCC) patients with clinical benefits remains unclear. This study aimed to assess the outcomes of HCC patients after ICI discontinuation.MethodsPatients with HCC were retrospectively screened and those discontinued ICI therapy in the absence of progressive disease (PD) were included. Responses at discontinuation were evaluated per response evaluation criteria in solid tumors (RECIST) version 1.1 and modified RECIST (mRECIST). Patients were classified into five subgroups according to the cause of discontinuation: complete response (CR), partial response (PR), stable disease (SD) per RESICT version 1.1, adverse event (AE), or others. Progression-free survival (PFS) and overall survival (OS) since ICI start or after ICI discontinuation were assessed.ResultsA total of 66 patients were included. The median follow-up was 29.33 months. The median PFS since ICI start was 30.83 months [95% confidence interval (CI): 24.93-36.72], and the median OS was not reached. The median PFS after discontinuation was 20.6 months (95% CI: 7.63-33.56), and the median OS after discontinuation was not reached. Univariate analysis showed that age, treatment after discontinuation, Response (RECIST version 1.1) at discontinuation and modified response (mResponse per mRECIST) at discontinuation were significantly associated with PFS after discontinuation, while age and mResponse at discontinuation were significantly associated with OS after discontinuation. Multivariate analysis further demonstrated that mResponse at discontinuation and treatment after discontinuation were independently associated with PFS after discontinuation, while age was independently associated with OS after discontinuation.ConclusionsICIs might be discontinued in HCC patients with a response of CR per mRECIST. Patients with a response of PR/SD per mRECIST or elder age could continue ICI therapy after achieving clinical benefits. Tyrosine kinase inhibitor (TKI) maintenance therapy might help to prevent progression after ICI discontinuation.

Project description:BACKGROUND:Since 2012, several immune checkpoint inhibitors have been approved by the Taiwan FDA for various types of cancer treatment. However, none of them are covered by Taiwan National Health Insurance due to the fact that they are expensive, and there is a lack of clinical evidence as to their effectiveness. OBJECTIVES:This study was aimed toward an exploration of clinical experiences with use of immune checkpoint inhibitors, including indications, prescription types, drug effectiveness, adverse drug event types, and incidence, all of which shall serve as references for future clinical drug use. METHODS:This is a retrospective study focusing on three immune checkpoint inhibitors (ipilimumab, nivolumab, and pembrolizumab), which are available for cancer treatment in Taiwan. We collected data from medical records for the period from January 1st, 2015 to January 12th, 2017 at National Cheng Kung University Hospital (NCKUH), a medical center in southern Taiwan, and recorded these cases until May 31st, 2017. Overall survival (OS) and progression-free survival (PFS) were estimated using the Kaplan-Meier method, and adverse drug reaction odds ratios were analyzed using a chi-square analysis. RESULTS:The 50 patients under consideration in this study had used any one of the immune checkpoint inhibitors in NCKUH. Non-small cell lung cancer (n = 24, 48%) accounted for the highest percentage, followed by hepatocellular carcinoma (n = 4, 8%). The median OS was not reached, and the PFS for all immunotherapies was 4.9 months. The median OS period and PFS for non-small cell lung cancer (NSCLC) patients were 13 and 4.9 months, respectively, which were similar to those in many clinical trials. For NSCLC patients, the OS and PFS were only 0.63 and 1.37 months for squamous cell type NSCLC, and for patients who were PD-L1 negative, the OS and PFS were only 11.53 and 2.6 months, respectively. The most common adverse events in this study included fatigue (42%), rashes (22%), nausea (20%), and fever (20%), while one patient developed severe deep venous thrombosis and tissue inflammation, which was not confirmed in previous clinical trials. CONCLUSIONS:The histological subtype, the intensity of the PD-L1 expression, and the timing of treatment affected the NSCLC therapeutic results. It is recommended that clinical tests be conducted in order to enhance therapeutic effectiveness. It is expected that more testing, observation-based studies, and research results will validate their efficacy and the tolerance levels of patients.

Project description:BackgroundImmune checkpoint inhibitors (ICIs) have substantially improved clinical outcomes in multiple cancer types and are increasingly being used in early disease settings and in combinations of different immunotherapies. However, ICIs can also cause severe or fatal immune-related adverse-events (irAEs). We aimed to identify and characterise cardiovascular irAEs that are significantly associated with ICIs.MethodsIn this observational, retrospective, pharmacovigilance study, we used VigiBase, WHO's global database of individual case safety reports, to compare cardiovascular adverse event reporting in patients who received ICIs (ICI subgroup) with this reporting in the full database. This study included all cardiovascular irAEs classified by group queries according to the Medical Dictionary for Regulatory Activities, between inception on Nov 14, 1967, and Jan 2, 2018. We evaluated the association between ICIs and cardiovascular adverse events using the reporting odds ratio (ROR) and the information component (IC). IC is an indicator value for disproportionate Bayesian reporting that compares observed and expected values to find associations between drugs and adverse events. IC025 is the lower end of the IC 95% credibility interval, and an IC025 value of more than zero is deemed significant. This study is registered with ClinicalTrials.gov, number NCT03387540.FindingsWe identified 31 321 adverse events reported in patients who received ICIs and 16 343 451 adverse events reported in patients treated with any drugs (full database) in VigiBase. Compared with the full database, ICI treatment was associated with higher reporting of myocarditis (5515 reports for the full database vs 122 for ICIs, ROR 11·21 [95% CI 9·36-13·43]; IC025 3·20), pericardial diseases (12 800 vs 95, 3·80 [3·08-4·62]; IC025 1·63), and vasculitis (33 289 vs 82, 1·56 [1·25-1·94]; IC025 0·03), including temporal arteritis (696 vs 18, 12·99 [8·12-20·77]; IC025 2·59) and polymyalgia rheumatica (1709 vs 16, 5·13 [3·13-8·40]; IC025 1·33). Pericardial diseases were reported more often in patients with lung cancer (49 [56%] of 87 patients), whereas myocarditis (42 [41%] of 103 patients) and vasculitis (42 [60%] of 70 patients) were more commonly reported in patients with melanoma (χ2 test for overall subgroup comparison, p<0·0001). Vision was impaired in five (28%) of 18 patients with temporal arteritis. Cardiovascular irAEs were severe in the majority of cases (>80%), with death occurring in 61 (50%) of 122 myocarditis cases, 20 (21%) of 95 pericardial disease cases, and five (6%) of 82 vasculitis cases (χ2 test for overall comparison between pericardial diseases, myocarditis, and vasculitis, p<0·0001).InterpretationTreatment with ICIs can lead to severe and disabling inflammatory cardiovascular irAEs soon after commencement of therapy. In addition to life-threatening myocarditis, these toxicities include pericardial diseases and temporal arteritis with a risk of blindness. These events should be considered in patient care and in combination clinical trial designs (ie, combinations of different immunotherapies as well as immunotherapies and chemotherapy).FundingThe Cancer Institut Thématique Multi-Organisme of the French National Alliance for Life and Health Sciences (AVIESAN) Plan Cancer 2014-2019; US National Cancer Institute, National Institutes of Health; the James C.
