Project description:BackgroundImmune checkpoint inhibitors (ICIs) in the setting of liver transplant (LT) pose a risk of rejection and hold unclear benefit in both the neoadjuvant (pre-transplant) and post-transplant salvage setting. In the pre-transplant setting, neoadjuvant ICIs may serve as a bridge to LT by downstaging disease burden to fit within transplant criteria. Outcomes in this setting include patients who had successful transplants without complications to patients who suffered severe complications, including fatal hepatic necrosis and graft failure requiring re-transplant. Some authors suggest having a period of three months between checkpoint inhibition and transplant may help mitigate adverse effects. In the post-LT setting, there are few treatment options if there is a recurrence of disease, which forces treatment teams to reconsider checkpoint inhibitors. Again, a longer period of time between transplant and checkpoint inhibition may reduce risk of rejection. Case reports of patients treated with ICIs post-transplant utilized either nivolumab or pembrolizumab. As combination atezolizumab/bevacizumab is a relatively new treatment option for unresectable hepatocellular carcinoma (HCC), there are only three reported cases using this combination in the post-LT setting. While there were no cases of rejection, all three cases had progression of disease. As immunotherapy joins transplantation as a mainstay of treatment for HCC, it remains unclear how to best navigate when the treatment course involves both immune activation and immunosuppression.Case descriptionPatients who had an LT and were treated with ICIs (pre or post LT) at the University of Cincinnati were included in this retrospective chart review.ConclusionsFatal rejection remains a significant risk even 4 years after LT. Neoadjuvant ICIs also pose a risk for acute cellular rejection; however, this may not always be clinically significant. Graft versus host disease (GVHD) may be an additional, previously unreported risk of ICIs in the setting of LT. Prospective studies are needed to understand benefits and risks of checkpoint inhibitors in the LT setting.

Project description:The utilization of immune-checkpoint inhibitors (ICIs) in cancer immunotherapy frequently leads to the occurrence of immune-related adverse events (irAEs), making it generally not recommended for patients with preexisting autoimmune diseases. Hence, we conducted a meta-analysis on safety and efficacy of ICIs in cancer patients with preexisting autoimmune diseases to provide further insights. PubMed, EMBASE, and Cochrane Library were systematically searched until December 20, 2024. The main summary measures used were pooled rate and risk ratio (RR) with 95% confidential interval (CI), which were analyzed using R statistic software. A total of 52 articles were included in the study. When cancer patients with preexisting autoimmune diseases received ICIs treatment, the overall incidence was 0.610 (95% CI: 0.531-0.686) for any grade irAEs, 0.295 (95% CI: 0.248-0.343) for flares, 0.325 (95% CI: 0.258-0.396) for de novo irAEs, 0.238 (95% CI: 0.174-0.309) for grade ≥3 irAEs, and 0.143 (95% CI: 0.109-0.180) for discontinuation due to immunotoxicity. Compared with those without autoimmune diseases, cancer patients with autoimmune diseases experienced a higher risk of any-grade irAEs (RR: 1.23, 95% CI: 1.12-1.35) and discontinuation due to immunotoxicity (1.40, 95% CI: 1.11-1.78). However, no statistically significant differences were observed in the incidence of grade ≥3 irAEs, objective response rate (ORR), disease control rate (DCR), overall survival (OS), and progression-free survival (PFS) between the two groups. During ICIs treatment, irAEs are common among cancer patients with autoimmune diseases, but severe irAEs is relatively low. ICIs are effective in this population, but should be strictly monitored when used to avoid immunotoxicity.

Project description:Immune-checkpoint inhibitors (ICIs) targeting cytotoxic T lymphocyte-associated antigen-4 and programmed cell death ligand-1) are associated with several immune-related neurological disorders. Cases of meningitis related to ICIs are poorly described in literature and probably underestimated. Several guidelines are available for the acute management of these adverse events, but the safety of resuming ICIs in these patients remains unclear. We conducted a retrospective case series of immune-related meningitis associated with ICIs that occurred between October 1 2015 and October 31 2019 in two centers: Saint-Louis and Cochin hospitals, Paris, France. Diagnosis was defined by a (1) high count of lymphocytes (>8 cells/mm3) and/or high level of proteins (>0.45 g/L) without bacteria/virus or tumor cells detection, in cerebrospinal fluid and (2) normal brain and spine imaging. Patients were followed-up for at least 6 months from the meningitis onset. Seven cases of immune-related meningitis are here reported. Median delay of meningitis occurrence after ICIs onset was 9 days. Steroid treatment was introduced in four patients at a dose of 1 mg/kg (prednisone), allowing a complete recovery within 2 weeks. The other three patients spontaneously improved within 3 weeks. Given the favorable outcome, ICIs were reintroduced in all patients. The rechallenge was well tolerated and no patients experienced meningitis recurrence. In conclusion, in our series, the clinical course was favorable and steroids were not always required. Resuming ICIs in these patients appeared safe and can thus be considered in case of isolated meningitis. However, a careful analysis of the risk/benefit ratio should be done on a case-by-case basis.

Project description:Penile squamous cell carcinoma (PSCC) is a rare malignancy, and first-line therapy typically involves cisplatin-based chemotherapy. However, these regimens are often unsuitable for patients with poor performance status or advanced age due to their toxicity. This retrospective, multicenter study evaluated patients with metastatic PSCC who received immune checkpoint inhibitor (ICI) therapy between 2017 and 2024. A total of 10 patients met the inclusion criteria. The median age was 75 years, and 50% had an ECOG performance status of 2 or higher. The objective response rate (ORR) was 30%, and the disease control rate (DCR) was 40%. The duration of response and disease control was over 12 months and 8 months respectively in all patients with response or disease control. The median progression-free survival (PFS) was 2.82 months, and the median overall survival (OS) was 4.32 months. PD-L1 and HPV-positive patients had a 67% response rate (n = 2/3). No patients experienced severe immune-related adverse events (irAEs). This multicenter retrospective analysis suggests that ICI monotherapy may be a promising treatment option for patients with advanced PSCC who are either ineligible for first-line platinum-based chemotherapy or who have progressed after platinum-based chemotherapy, including those with poor performance status. Further studies are needed to confirm these findings and identify baseline patient characteristics that may optimize selection criteria.

Project description:BackgroundAngiosarcoma is an uncommon endothelial malignancy and a highly aggressive soft tissue sarcoma. Due to its infiltrative nature, successful management of localized angiosarcoma is often challenging. Systemic chemotherapy is used in the metastatic setting and occasionally in patients with high-risk localized disease in neoadjuvant or adjuvant settings. However, responses tend to be short-lived and most patients succumb to metastatic disease. Novel therapies are needed for patients with angiosarcomas.MethodsWe performed a retrospective analysis of patients with locally advanced or metastatic angiosarcoma, who were treated with checkpoint inhibitors at our institution. We collected their clinical information and outcome measurements. In one patient with achieved complete response, we analyzed circulating and infiltrating T cells within peripheral blood and tumor tissue.ResultsWe have treated seven angiosarcoma (AS) patients with checkpoint inhibitors either in the context of clinical trials or off label [Pembrolizumab + Axitinib (NCT02636725; n = 1), AGEN1884, a CTLA-4 inhibitor (NCT02694822; n = 2), Pembrolizumab (n = 4)]. Five patients had cutaneous angiosarcoma, one primary breast angiosarcoma and one radiation-associated breast angiosarcoma. At 12 weeks, 5/7 patients (71%) had partial response of their lesions either on imaging and/or clinical exam and two (29%) had progressive disease. 6/7 patients are alive to date and, thus far, 3/7 patients (43%) have progressed (median 3.4 months)- one achieved partial response after pembrolizumab was switched to ongoing Nivolumab/Ipilimumab, one died of progressive disease at 31 weeks (primary breast angiosarcoma) and one was placed on pazopanib. One patient had a complete response (CR) following extended treatment with monotherapy AGEN1884. No patient experienced any ≥ grade 2 toxicities.ConclusionsThis case series underscores the value of targeted immunotherapy in treating angiosarcoma. It also identifies genetic heterogeneity of cutaneous angiosarcomas and discusses specific genetic findings that may explain reported benefits from immunotherapy.

Project description:Immune checkpoint inhibitors (ICI) are revolutionizing care for cancer patients. The list of malignancies for which the Food and Drug Administration is granting approval is rapidly increasing. Furthermore, there is a concomitant increase in clinical trials incorporating ICI. However, the safety of ICI in patients undergoing surgery remains unclear. Herein, we assessed the safety of ICI in the perioperative setting at a single center. We conducted a retrospective review of patients who underwent planned surgery while receiving ICI in the perioperative setting from 2012 to 2016. We collected 30-day postoperative morbidity and mortality utilizing the Clavien-Dindo classification system. We identified 17 patients who received perioperative ICI in 22 operations. Patients were diagnosed with melanoma (n = 14), renal cell carcinoma (n = 2), and urothelial carcinoma (n = 1). Therapies included pembrolizumab (n = 10), ipilimumab (n = 5), atezolizumab (n = 5), and ipilimumab/nivolumab (n = 2). Procedures included cutaneous/subcutaneous resection (n = 6), lymph node resection (n = 5), small bowel resection (n = 5), abdominal wall resection (n = 3), other abdominal surgery (n = 3), orthopedic surgery (n = 1), hepatic resection (n = 1), and neurosurgery (n = 2). There were no Grade III-IV Clavien-Dindo complications. There was one death secondary to ventricular fibrillation in the setting of coronary artery disease. ICI appear safe in the perioperative setting, involving multiple different types of surgery, and likely do not need to be stopped in the perioperative setting. Further studies are warranted to confirm these findings.

Project description:BackgroundAdrenal insufficiency (AI) represents a rare, yet potentially life-threatening immune checkpoint inhibitor (ICI)-related adverse event. The clinical characteristics of ICI-induced AI are still poorly defined due to its low incidence but need to be comprehensively understood.MethodsWe systematically retrieved and screened the PubMed/Medline, Embase, Web of Science, and Cochrane Library databases for all articles published on AI related to anti-cytotoxic T-lymphocyte antigen 4 (CTLA-4), anti-programmed cell death protein-1 (PD-1) receptor or its ligand (PD-L1), or combination ICI therapy. The retrieved articles were reviewed and selected in accordance with the exclusion criteria. The detailed data of individual cases were then collected and analyzed.ResultsWe identified 206 ICI-induced AI patients, comprising 11 (5.3%) primary AI patients, 191 (92.7%) secondary AI patients, and 4 (1.9%) mixed-type AI patients. The subclassification of the secondary AI patients, comprising 108 isolated adrenocorticotropic hormone (ACTH) insufficiency (IAD) and 83 multiple pituitary hormone deficiency (MPHD) patients, revealed that 56.5% of secondary AIs were related to IAD. Fatigue, anorexia/loss of appetite, headache, and nausea/vomiting were the most prevalent symptoms, and MPHD patients had a significantly higher rate of headache than primary AI patients and IAD patients (67.2% vs. 9.1% vs. 10.2%; P=0.000). Further, anti-PD-1-induced AI patients showed more complex and poorer clinical manifestations than anti-CTLA-4-induced patients, including a higher rate of emergency admission (28.7% vs. 4.9%; P=0.003), tachycardia (30.4% vs. 0; P=0.014), hypotension (50.0% vs. 8.6%; P=0.000), hypoglycemia (19.5% vs. 2.6%; P=0.014), hyponatremia (64.2% vs. 33.3%; P=0.002), and a prolonged median duration from ICI initiation to symptom onset (26 vs. 9 weeks; P=0.000).DiscussionThe ICI-induced AI events could be primary, secondary, or mixed-type, and IAD was the most common reason for such events. The symptoms were usually unspecific and could be complex. AI should be excluded in a timely manner, and the patients should be followed-up with and receive extra attention for AI events even after the discontinuation of ICI treatment. Additionally, the discrepancy in relation to clinical characteristics between anti-PD-1- and anti-CTLA4-induced AI events warrants further exploration.

Project description:Background and Objective: Immune checkpoint inhibitors (ICIs) combined with angiogenesis inhibitors may have synergistic effects in elderly patients with advanced driver-negative NSCLC, but its true efficacy remains unclear. In addition, chemotherapy tolerance in elderly NSCLC patients is poor, and the precise identification of the population that may benefit from ICIs combined with angiogenesis inhibitors is also the focus of current research. Methods: We retrospectively compared the efficacy and safety of ICIs combined with or without antiangiogenic agents in elderly patients with advanced driver-gene negative NSCLC ≥65 years of age in the Cancer Center of Suzhou Hospital Affiliated to Nanjing Medical University. The primary endpoint was PFS. Secondary endpoints were OS, ORR, and immune-related adverse events (irAEs). Results: A total of 36 patients in the IA group (immune checkpoint inhibitors plus angiogenesis inhibitors group) and 43 patients in the NIA group (immune checkpoint inhibitors without angiogenesis inhibitors group) were enrolled in the study between January 1, 2019 and December 31, 2021. The median follow-up time for patients in the IA group and NIA group was 18.2 months (95%CI: 14 - 22.5 months) and 21.4 months (95%CI: 16.7 -26.1 months), respectively. The median PFS and median OS were longer in the IA group compared to the NIA group (8.1 months vs 5.3 months; HR for PFS: 0.778, 95%CI: 0.474-1.276, P=0.32; NA vs 30.9 months; HR for OS: 0.795, 95%CI: 0.396-1.595, P=0.519). There were no significant differences in median PFS and median OS between the two groups. Subgroup analysis showed that patients in the IA group had significantly longer PFS in the subgroup with PD-L1 expression ≥50% (P=0.017), and the association between different groups and disease progression was still different in the two subgroups (P for interaction = 0.002). There was no significant difference in ORR between the two groups (23.3% vs 30.5%, P=0.465). The incidence of irAEs in the IA group was lower than that in the NIA group (39.5% vs 19.4%, P=0.05), and the cumulative incidence of treatment interruptions due to irAEs was significantly reduced (P=0.045). Conclusion: In elderly patients with advanced driver-negative NSCLC, the addition of antiangiogenic agents to ICIs therapy did not provide significant clinical benefit, but the incidence of irAEs and treatment interruptions due to irAEs was significantly reduced. In the subgroup analysis, we found that the clinical benefit of this combination therapy was observed in patients with PD-L1 expression ≥50%, which warrants further exploration.

Project description:BackgroundAntinuclear antibodies (ANAs) predicting the safety and efficacy of patients with advanced non-small cell lung cancer (NSCLC) treated with immune checkpoint inhibitors (ICIs) are still a matter of debate considering previous studies showed quite different results based on different ANA cut-off values. Thus, we investigated the associations between different ANA titers and the safety and efficacy of ICIs. Moreover, we also briefly discussed the effects of anti-thyroglobulin (ATG) and anti-thyroid peroxidase (ATPO) on the safety of ICIs.MethodsA total of 159 Chinese patients confirmed to have locally-advanced or metastatic NSCLC given ICIs or chemoimmunotherapy in Peking Union Medical College Hospital from January 2015 to December 2020 were analyzed retrospectively and were followed up until December 2020 or death or loss to follow-up. Patients' characteristics were retrieved from medical records. ANAs were detected by the indirect immunofluorescence assay, ATG and ATPO by the electrochemiluminescence immunoassay. The severity of immune-related adverse events (irAEs) was graded according to the Common Terminology Criteria for Adverse Events (CTCAE 5.0) and the efficacy was evaluated by the Response Evaluation Criteria in Solid Tumors (RECIST 1.1).ResultsThe incidence of irAEs, median progression-free survival (mPFS) of the ANA negative and positive groups were 26.0% vs. 31.4% (P=0.457), 17.7 vs. 10 months (P=0.603) for the cut-off value of 1:80; 26.2% vs. 33.9% (P=0.305), 11.9 vs. 10.6 months (P=0.957) for 1:160; and 25.9% vs. 45.8% (P=0.047), and 11.9 vs. 7.7 months (P=0.471) for 1:320, separately. Besides, ANA titer ≥1:320 was associated with irAEs [odds ratio (OR) =4.9, 95% confidence interval (CI): 1.45-16.52, P=0.01] and the incidence of adverse skin reactions differed greatly between the negative and positive groups (9.7% vs. 32%, P=0.003). Moreover, a total of 52 out of 159 patients were tested for ATG and ATPO. 46 patients were negative and 6 were positive, with the incidence of abnormal thyroid function being 4.3% vs. 50% (P=0.005), respectively.ConclusionsPreexisting ANAs may not correlate with the clinical benefit of immunotherapy in patients with NSCLC but may be associated with adverse skin reactions. Besides, ATG or ATPO has the potential to predict thyroid dysfunction.

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.
