Abstract
Background On February 24th, 2022, a full-scale armed conflict broke out in Ukraine, resulting in a significant impact on the healthcare system, as well as extensive damage to the country's infrastructure. The aim of this study was to assess the challenges faced by oncologists in providing cancer care to patients.Methods Data were collected through a structured self-administered questionnaire administered using the Google survey tool and distributed to all participants.Results This was a cross-sectional study that involved 111 oncology specialists. Physicians practising in regions that were partially or temporarily occupied by the Russian army (Chernihiv and Zaporizhzhia) reported a significantly higher decline in patient numbers compared to physicians in unoccupied regions (70.0% vs 20.9%; p < 0.0001). Most physicians from both occupied and unoccupied regions reported an increase in the number of patients with advanced disease (65.0% vs. 65.9%; p = 0.735). The majority of physicians from both occupied and unoccupied regions did not see loss of information, changes in cancer treatment phases, and self-medication as a concern. The majority were satisfied with the availability of medicines and equipment.Conclusion This needs-based assessment is crucial for improving the quality of cancer care as it provides valuable information for designing public health interventions.
