Abstract
PURPOSE: To report real-world compliance to radiation in gynecologic cancers during the complete lockdown phase of COVID-19 pandemic. METHODS AND MATERIALS: From March 23, 2020, until June 30, 2020, complete lockdown was imposed in India. During this period there was restructuring of cancer care and radiation oncology department due to operational policies prevalent in the institution, and the care for gynecological cancer was based on the evolving international recommendations. Institutional review board approval was obtained to audit patterns of care during the complete lockdown phase. Descriptive variables were used to report on patient characteristics, compliance, delays, toxicity, and observed deviations in recommended care.Entities:

Excluding palliative and noncompliant and referred out patients EQD2 delivered is lesser than that generated by physical dose addition of the treatment regimen as most of the treatment plans were optimized to ensure the best therapeutic ratio between the target and organ at risk.
