Background: The SARS‑CoV‑2 pandemic has also had a profound impact on

cancer treatment delivery and organization. Oncology clinics have developed

a number of procedures and used formulas related to radiotherapy doses to

continue their activities. Aims and Objectives: We explored the impact of SARSCoV-

2 pandemy on the personnel and cancer patients undergoing radiotherapy

in a radiotherapy department during the first year. Materials and Methods:

845 patients were treated over the course of a year, 195 of whom consented to

participate in the study. The Elekta Mozoiq system and radiotherapy cards were

evaluated, and the time intervals between the treatments during the radiotherapy

were recorded. Biologically Effective Dose losses were calculated in the

radiotherapy dose due to the interruption to treatment, and necessary calculations

were made for the delivery of the initially planned dose. Results: The mean age

of the patients was 59 years (range 19-78). There were 110 male (56.4%) and 85

female (43.5%) participants. The treatment of 4.6% (9 patients) of the patients was

discontinued because of SARS-CoV-2 infection during radiotherapy. The greatest

added fraction for a patient with prostate cancer was three while the lowest was

one for a patient with lung cancer, based on the TDF calculation. During this

period, 16% of the staff was infected with COVID-19. Conclusion: This study

demonstrates the effect of the COVID-19 pandemy on patients and personnel in a

radiotherapy clinic, and its management during one year.
