Pre-immunotherapy serum hsTnT concentrations were often asymptomatically elevated in individuals with advanced pores and skin tumor, none of them of whom consequently developed irM during ICI therapy. However, large studies are required to assess the positive and negative predictive ideals of hsTnT for the development of irM. In the meantime, elevated hsTnT concentrations should be investigated before initiation of immunotherapy and closely monitored during early treatment cycles, where the risk of irM is definitely greatest. 0.05 were considered statistically significant. Results Between the 1st of January 2018 and the 31st of December 2019, a total of 121 individuals received ICI therapy for locally advanced or metastatic melanoma and non-melanoma pores and skin tumor (Flowchart). Eighty-one individuals were male, and 40 individuals were female, having a mean age of 74 years. The vast majority of the individuals (96%) were treated for melanoma. Of these 116 individuals, almost two-thirds were treated in the palliative establishing for high-risk resected melanoma (stage IV), and the remaining third received ICI therapy in the adjuvant context (Table 1). Of the 77 individuals receiving palliative treatment, 47 received combined anti-CTLA4 and anti-PD1 therapy, with the remaining individuals receiving monotherapy with pembrolizumab (9) or nivolumab (21). Five individuals with non-melanoma pores and skin cancer were treated with immune checkpoint inhibitors, two with locally advanced squamous cell carcinoma (cemiplimab, anti-PD1), and three with metastatic Merkel cell carcinoma (avelumab, anti-PD-L1).

Following antibiotic and antiviral treatment, along with tapering of his immunosuppressive therapy, the patient was discharged to a rehabilitation unit after 68 days of in-patient care. Following 4 weeks of rehabilitation, the patient was discharged home but died 4 weeks later on of cardiac failure, some 20 weeks after the administration of cemiplimab.

Fifty-six out of 121 individuals experienced preexisting cardiac comorbidities before initiating immunotherapy (Number 3A). Baseline echocardiography was available for 59 individuals, which were irregular in 33 individuals. Given that we launched routine pre-immunotherapy baseline hsTnT measurement in 2019, based on the American Society of Clinical Oncology (ASCO) recommendations (28), we were able to collect data for 47 individuals (Table 2). HsTnT was measured using SPN the Elecsys Assay (Roche), according to the manufacturer’s instructions, and was elevated in 28% of individuals (13 out of 47) in the absence of any medical symptoms. Ten experienced preexisting cardiac comorbidities (77%), including arrhythmias, chronic heart failure, and coronary artery disease. Five of those individuals had additionally elevated baseline creatinine levels (38%), and 46% experienced elevated NT-proBNP natriuretic-peptide concentrations.

There was no association between hsTnT concentration and sex or BRAF status (in individuals with melanoma) (Fisher’s precise test). Individuals with elevated hsTnT levels were significantly older (Number 3B) and experienced significantly improved serum creatinine levels (Figure.
