Retrospective Impact of COVID-19 Pandemic on Primary Breast Cancer Care.

Background: The COVID-19 pandemic has transformed breast cancer care for patients and healthcare providers. Circumstances varied greatly by region and hospital, depending on COVID-19 prevalence, case mix, hospital type, and available resources. These challenges have disrupted screening programs and have been particularly distressing for both women with a breast cancer diagnosis and their providers.

Summary: This review explores the retrospective impact of the COVID-19 pandemic on primary breast cancer care. It analyzes changes in screening participation, diagnosis rates, treatment modalities, and the delivery of psycho-oncological support during the pandemic. The study found a significant reduction in breast cancer screenings and a subsequent stage shift in diagnoses, with fewer early-stage and more advanced-stage cancers being detected. Additionally, the review discusses the psychosocial challenges faced by patients and the adaptations made in care delivery, such as the increased use of telemedicine. Despite these challenges, the healthcare systems showed resilience, with core treatment services largely maintained and rapid adaptations to new care models.

Key Messages: There was a marked decrease in breast cancer screenings and early diagnoses during the pandemic, with a shift toward more advanced-stage detections. While there was an increased use of neoadjuvant therapies and telemedicine, essential breast cancer treatments were mostly sustained, reflecting the resilience of healthcare systems. The pandemic significantly impacted the mental health of breast cancer patients, exacerbating anxiety and depression and highlighting the need for improved psycho-oncological support. The full impact of these disruptions on long-term breast cancer outcomes remains uncertain, necessitating ongoing monitoring and adaptation of care strategies to mitigate adverse effects.
