Insights
The COVID-19 pandemic led to fewer visits for malignant melanoma diagnosis and treatment. This resulted in a rise of advanced and metastatic melanoma cases due to delayed medical care.
Area of Science:
- Oncology
- Public Health
- Dermatology
Background:
- The COVID-19 pandemic significantly altered public healthcare perceptions and clinic attendance.
- Malignant melanoma, a serious skin cancer, continued to affect patients despite the pandemic.
Purpose of the Study:
- To assess the impact of the COVID-19 first lockdown in Israel on malignant melanoma patient visits and treatment.
- To compare malignant melanoma care during the pandemic with previous years.
Main Methods:
- A survey analyzed outpatient clinic and oncology department visits for malignant melanoma.
- Data from the first lockdown in 2020 were compared to the same periods in prior years (2018, 2019).
Main Results:
- Attendance for suspected malignant melanoma excisions and follow-ups decreased significantly during the lockdown.
- A notable increase in new malignant melanoma treatment protocols was observed in late 2020, unlike in 2018 or 2019.
- This suggests a rise in advanced and metastatic cases due to deferred care.
Conclusions:
- Delaying malignant melanoma treatment during the COVID-19 pandemic led to an increase in advanced disease.
- Continued medical attention for non-COVID-19 diseases, like melanoma, is crucial for patient outcomes.
Abstract:
The Novel Coronavirus disease (COVID-19) first emerged in Wuhan province, China, in late November 2019 and changed public healthcare perception. It has caused a significant decline in attendance to outpatient clinics. However, other diseases have not stopped, including malignant melanoma. Survey of the number of visits to plastic surgery outpatient clinic during the first lockdown in Israel concerning malignant melanoma was compared to the same months in the previous years. We assessed the number of visits to the oncology department during 2020 compared to the number of visits and treatment protocols for malignant melanoma. During the first lockdown, the attendance at the plastic surgery outpatient clinic and ambulatory surgery decreased significantly (P = 0.002), both in excisions of suspected malignant melanoma and malignant melanoma follow-ups (P = 0.019 and P = 0.035, respectively). The last third of 2020 (from September to December) had shown a significant rise in new protocols commenced (P < 0.001). This rise in the final third of the year was not noted in 2018 or 2019. These data clearly show the rise in advanced and metastatic malignant melanoma cases due to refraining from medical follow-ups and treatments during the COVID-19 pandemic. Diseases other than COVID-19 have not vanished, and continue to treat those diseases. Ignoring malignant melanoma treatment because of COVID-19 and vice-versa will not benefit our patients.
