New algorithms that aim to sustain balance between management of oncological patients and the need to maintain a sufficient amount of resources were adapted.Methodology This retrospective study reviewed the patients with gynecological cancer operated in our hospital during the first lockdown period in Greece (between 13 March 2020 and 30 May 2020) and compared the results with the corresponding time period in 2019 before COVID-19 pandemic. We also examine the number of patients that were referred for neoadjuvant chemotherapy or radiotherapy between those periods.Result(s)*The gynecological oncological operations performed during the lockdown period of the first pandemic wave were not altered by the outbreak (153 in 2019 vs 130 in 2020) (figure 1). There was no difference in ovarian cancer surgeries (34 vs 31) and the number of primary debulking was not affected (20 vs 19). The patients referred to neoadjuvant chemotherapy was the same between the two periods. No significant difference was obtained in the endometrial, vaginal and cervical cancer surgeries and the number of surgically treated recurrences. Contrastingly there was a significant decrease in endoscopic procedures and diagnostic biopsies (72 vs 53) and the fertility sparring surgeries were postponed from patients at a later date (table 1).Abstract 798 Figure 1 Gynecological cancer surgeries on both periodsView this table:Abstract 798 Table 1 Type of procedures on both periodsConclusion*The findings of our study suggest that at the first wave of the pandemic lockdown, the operations conducted in our department did not alter. In accordance with international consensus guidelines the stage, the grade and the type of cancer, and the potential comorbidities were the main factors that accounted for the decision of the optimal mode of treatment.
