Peripheral Blood Biomarkers Predictive of Efficacy Outcome and Immune-Related Adverse Events in Advanced Gastrointestinal Cancers Treated with Checkpoint Inhibitors.

ABSTRACT:

Background

Gastrointestinal cancers constitute a major burden of global cancer mortalities. In recent years, the advent of immune checkpoint inhibitors has greatly improved the survival of patients with advanced gastrointestinal cancers, while predictive biomarkers of treatment efficacy and toxicities are still unmet demands.

Methods

In our retrospective study, patients with advanced gastrointestinal cancers who received single or double immune checkpoint inhibitors in the Department of Gastrointestinal Oncology in Peking University Cancer Hospital between July 2016 and February 2022 were enrolled. Records of clinicopathological information, survival parameters, safety data, and baseline and posttreatment peripheral blood constituents were retrieved. Cox regression analysis and logistic regression analysis were performed to identify the predictive factors of treatment outcomes and immune-related adverse events.

Results

We demonstrated that early treatment lines, the presence of immune-related adverse events, and a lower C2 neutrophil-to-lymphocyte ratio were independent factors predicting a superior objective response rate and progression-free survival in patients treated with immunotherapy. Lower ECOG PS, higher baseline albumin, and lower C2 neutrophil-to-lymphocyte ratios were independent risk factors for the onset of immune-related adverse events. Patients who succumbed to immune-related adverse events during immunotherapy presented better survival.

Conclusion

Our results indicate that peripheral blood markers have potential for predicting treatment outcomes and immune-related adverse events in patients with advanced gastrointestinal cancer. Prospective validations are warranted.

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:BackgroundImmune checkpoint inhibitors (ICIs) have dramatically improved survival in advanced gastrointestinal (GI) cancer patients, but also resulted in immune-related adverse events (irAEs). This study aimed to evaluate serological biomarkers of irAEs and treatment response in GI cancer patients.Patients and methodsMetastatic GI cancer patients were enrolled between August 1, 2015, and July 31, 2017. Serum samples were collected at baseline, and a panel of 59 serum biomarkers was tested. The occurrence of irAEs was analyzed, and serological biomarker expression was correlated with irAE incidence and prognosis.ResultsFifty-one patients were enrolled, of whom 47.1% (24/51) were diagnosed with irAEs, including 4 patients (7.8%) with grade 3-5 irAEs. The most common irAE was thyroiditis (9/51, 17.6%), followed by colitis (7/51, 13.7%). The expression of CD28 (P = 0.042), IL-4 (P = 0.033), IL-15 (P = 0.024) and PD-L1 (P = 0.018) was significantly elevated in patients with grade 3-5 irAEs. For organ-specific irAEs, IL-6 levels were higher in patients with thyroiditis and colitis, while IL-22 and SCF levels were higher in patients with colitis. Increased IL-1α, IL-21, LIF, and PIGF-1 levels were significantly associated with myositis incidence, while the serum levels of six cytokines (BTLA, GM-CSF, IL-4, PD-1, PD-L1 and TIM-3) were higher in patients with rash. Prognostic analysis showed that patients with irAEs had better tumor response (P = 0.029), improved PFS (median survival: undefined vs. 2.1 months, P = 0.002), and extended OS (median survival: undefined vs. 4.3 months, P = 0.003). The prognostic value of irAEs was only significant in patients who received anti-PD-1 inhibitors, but not in those who received anti-PD-L1 inhibitors. Besides, elevated BTLA (median OS: not reached vs. 7 months; P = 0.0168) and PD-1 (median OS: not reached vs. 7 months; P = 0.0223) concentrations were associated with longer OS.ConclusionsSerological proteins are promising markers for predicting immune-related toxicity and prognosis in GI cancer patients. Organ-specific irAEs have various cytokine profiles. Although further validation is needed before clinical application, this study provided a direction for identifying patients at risk for irAEs, and guiding patient selection for ICI therapy.

Project description:Immune related adverse events (irAEs) occur due to the inflammatory side effects of immune check point inhibitors (ICIs) and irAEs have been associated with improved efficacy in advanced non-small lung cancer (NSCLC) patients. Corticosteroids can reduce the efficacy of ICIs due to their immunosuppressive effects. In this study, we aimed to show the effects of the development of irAEs and the use of ≥ 10 mg prednisone and equivalent steroids on treatment response. We analyzed the outcomes of patients with NSCLC treated with ICIs as monotherapy or ICIs in combination with chemotherapy (ChT) at a single academic center based on the presence of irAEs and the use of corticosteroids. A landmark analysis was performed due to the time-dependent nature of irAEs. 90 patients were included in the study. irAEs were seen in a total of 45 (50%) patients. In the landmark analysis, the median overall survival (OS) was 52.1 months in those who developed irAEs and 14.4 months in those who did not (HR 2.71, 95% CI (1.55-4.73), p < 0.001), and the median progression-free survival (PFS) was also higher in the patients with irAEs (25.9 vs. 8.4 months, HR 2.54, 95% CI (1.52-4.25), p < 0.001). The objective response rate (ORR) was significantly higher in patients experiencing irAEs than without irAEs: 60% versus 33.3%, respectively (p = 0.011). The number of patients using steroids was 22 (24%), while 68 patients (76%) were not using steroids. There was no significant difference in mOS: 26.5 versus 28.7 months (HR 1.14, 95% CI (0.63-2.08), p = 0.652) and mPFS: 16.9 versus 13.5 months (HR 0.99, 95% CI (0.57-1.74), p = 0.997) between patients who used steroids and those who did not. ICIs efficacy is higher in patients who developed irAEs. In our analyses, the grade of irAEs or the number of irAEs occurring in the individual had no effect on mOS and mPFS. In our patient group, steroid use was mostly related with irAEs, and we did not detect any negative effects of corticosteroid use on PFS and OS.

Project description:BackgroundIn the context of patients with hepatocellular carcinoma (HCC) treated with systemic therapy, the correlation between the appearance of adverse events (AEs) and reported efficacy outcomes is well-known and widely investigated. From other pathological settings, we are aware of the prognostic and predictive value of the occurrence of immune-related AEs in patients treated with immune-checkpoint inhibitors.ObjectiveThis retrospective multicenter real-world study aims to investigate the potential prognostic value of AEs in patients with HCC treated with atezolizumab plus bevacizumab in the first-line setting.Patients and methodsThe study population consisted of 823 patients from five countries (Italy, Germany, Portugal, Japan, and the Republic of Korea).ResultsOf the patients, 73.3% presented at least one AE during the study period. The most common AEs were proteinuria (29.6%), arterial hypertension (27.2%), and fatigue (26.0%). In all, 17.3% of the AEs were grade (G) 3. One death due to bleeding was reported. The multivariate analysis confirmed the appearance of decreased appetite G < 2 [versus G ≥ 2; hazard ratio (HR) 0.60; 95% confidence interval (CI) 0.13-0.90; p < 0.01] and immunotoxicity G < 2 (versus G ≥ 2; HR: 0.70; 95% CI 0.24-0.99; p = 0.04) as independent prognostic factors for overall survival, and the appearance of decreased appetite G < 2 (versus G ≥ 2; HR: 0.73; 95% CI 0.43-0.95; p = 0.01), diarrhea (yes versus no; HR: 0.57, 95% CI 0.38-0.85; p = 0.01), fatigue (yes versus no; HR: 0.82, 95% CI 0.65-0.95; p < 0.01), arterial hypertension G < 2 (versus G ≥ 2; HR: 0.68, 95% CI 0.52-0.87; p < 0.01), and proteinuria (yes versus no; HR: 0.79, 95% CI 0.64-0.98; p = 0.03) as independent prognostic factors for progression-free survival.ConclusionsAs demonstrated for other therapies, there is also a correlation between the occurrence of AEs and outcomes for patients with HCC for the combination of atezolizumab plus bevacizumab.
