ABSTRACT
Background: Immune checkpoint inhibitors (ICIs) have revolutionized the treatment of advanced stage skin malignancies. Immunotherapy related adverse events (irAE) are toxicities associated with ICI therapy. Myocarditis is a rare life-threatening irAE. We attempt to characterize cases of myocarditis related to ICI therapy that have occurred since the start of the COVID-19 pandemic. Methods: We performed a single-center, retrospective cohort analysis of patients with advanced stage skin cancers who were treated with ICIs and identified cases of ICI-mediated myocarditis. ICI-mediated myocarditis was defined as evidence of myocardial injury in the setting of irAEs and exclusion of cardiovascular causes. Clinicopathologic variables and clinical outcomes were assessed in these patients. Results: A review of 361 patients that received ICI from 9/2014 - 10/2019 found 0 cases of ICI-mediated myocarditis. From 11/2019 - 12/2021, an additional 425 patients were identified of whom 11 (2.6%) developed ICI-mediated myocarditis. 10 patients had melanoma and 1 patient had Merkel cell carcinoma. 10/11 patients were male. 9/11 were treated with anti-PD-1 monotherapy and 2/11 were treated with ipilimumab with nivolumab. All patients had elevated high sensitivity troponin (median 361 pg/mL on presentation, reference range 0-19 pg/mL). 11/11 patients presented with elevated CPK (median 1734 IU/L, reference range 38-240 IU/L) and 8/11 presented with elevated AST:ALT ratio (median 1.58:1) on routine screening which prompted further investigation. 1 patient tested positive for COVID-19 13 days after initial biochemical concern for myocarditis, and 5 patients had received COVID-19 vaccines between 2.5-11 months prior to myocarditis onset. All patients were treated with high dose steroids, and 4 were treated with abatacept. 2 patients died within 30 days after diagnosis of myocarditis and 2 patients later died from malignancy progression. 2 patients developed progressive disease and 1 was successfully rechallenged with ICI with no myocarditis recurrence. 2 patients remain on active surveillance, 2 continue on a steroid taper, and 1 was lost to follow up. All patients with at least 5 months of follow up from myocarditis onset (n = 5) had persistently elevated HS-troponin despite normalization of CPK levels. Conclusions: In this single center study, we noted an increase in the frequency of ICI-mediated myocarditis in patients with advanced skin cancers during the pandemic era (2.6% vs 0% prepandemic) which is higher than reported in the literature (0.04-1.14%). The impact of COVID-19 during this time is suspicious and warrants further investigation. Therefore, we suggest heightened awareness in the COVID-19 era that elevated CPK levels and AST:ALT ratios merits further diagnostic investigation of ICI-mediated myocarditis.
ABSTRACT
Background: There was rapid adoption of teleoncology at Veterans Health Administration (VHA) during the COVID-19 pandemic. One-third of 9 million VHA-enrolled Veterans live in rural areas. While digital solutions can expand capacity, enhance care access, and reduce financial burden, they may also exacerbate rural-urban health disparities. Careful evaluation of patients' perceptions and policy tradeoffs are necessary to optimize teleoncology post-pandemic. Methods: Patients with ≥1 teleoncology visit with medical, surgical, or radiation oncology between March 2020 and June 2020 identified retrospectively. Validated, Likert-type survey assessing patient satisfaction developed. Follow-up survey conducted on patients with ≥1 teleoncology visit from August 2020 to January 2021. Travel distance, time, cost, and carbon dioxide (CO2) emissions calculated based on zip codes. Results: 100 surveys completed (response rate, 62%). Table with demographics. Patients overall satisfied with teleoncology (83% 'Agree' or 'Strongly Agree') but felt less satisfied than in-person visits (47% 'Agree' or 'Strongly Agree'). Audiovisual component improved patient perception of involvement in care (two-sided, p = 0.0254), ability to self-manage health/medical needs (p = 0.0167), and comparability to in person visits (p = 0.0223). Follow-up survey demonstrated similar satisfaction. Total travel-related savings: 86,470 miles, 84,374 minutes, $49,720, and 35.5 metric tons of CO2).Conclusions: Veterans are broadly satisfied with teleoncology. Audiovisual capabilities are critical to satisfaction. This is challenging for rural populations with lack of technology access. Patients experienced financial and time savings, and society benefitted from reduced carbon emissions. Continued optimization needed to enhance patient experience and address secondary effects.
