“…A nationwide study developed in the Netherlands revealed only a minor shift towards more advanced melanoma stages during the first lockdown and no impact afterwards (37). Klepfisch et al found no clinical or histopathological differences in the number of melanomas diagnosed after the lockdown compared to the pre-lockdown period and reported a minimal impact of COVID-19 lockdown on the diagnosis of melanoma, however, other studies reported the contrary (38). One possible explanation for the difference between data reported in different countries could be the different magnitude of the pandemic throughout the world (21,24,39).…”

BackgroundThe COVID-19 pandemic disrupted the healthcare system and negatively affected the diagnosis and management of melanoma worldwide. The purpose of this study is to investigate the long-term effects of the COVID-19 pandemic on the diagnosis and prognosis of melanoma.Materials and methodsThis retrospective cohort study included histopathologically confirmed melanoma cases from March 2019 to February 2023 in Cluj and Bihor counties. Data from the post-COVID-19 period (March 2021 to February 2023) were compared to the pre-COVID-19 period (March 2019 to February 2020) and the COVID-19 period (March 2020 to February 2021). Patient characteristics, monthly diagnostics, histological subtypes, and key histological features were analyzed using statistical tests.ResultsThe number of melanoma cases diagnosed annually decreased by 31.37 and 23.75% in the first and second post-pandemic years, respectively, compared to pre-pandemic numbers. Diagnostic rates also decreased by 14.9 and 5.4% in the first and second post-pandemic years, respectively, compared to the pandemic period. Prognostic factors worsened in the post-pandemic period, with higher Breslow index and mitotic rate, and increased ulceration and thick melanomas compared to the pre-pandemic period.ConclusionThe COVID-19 pandemic had a long-lasting impact on the diagnosis of melanoma in Romania, resulting in advanced stages and unfavorable prognostic factors. Larger global studies are needed to comprehensively understand the pandemic’s long-term effects on the diagnosis of melanoma.
