ABSTRACT
PURPOSE: The prognostic role of endometriosis amongst women with ovarian clear cell carcinoma (OCCC) remains debatable. The aim of this study was to ascertain the effect of endometriosis on the prognosis of OCCC. METHODS: A retrospective review of the medical records of 94 women diagnosed and treated for OCCC at a tertiary gynaecological cancer centre in the UK, spanning the period 2010-2019. Women were divided into two groups according to the presence of endometriosis. Clinico-pathological characteristics, progression-free survival (PFS) and overall survival (OS) were collated between the two groups. RESULTS: Forty-six cases of endometriosis-free OCCC (Ef-OCCC) were collated with 48 cases of endometriosis-related OCCC (Er-OCCC). There was no significant difference between the two groups regarding age (p-value = 0.2), FIGO stage (p-value = 0.8), residual disease (RD) (p-value = 0.07), adjuvant chemotherapy agent (p-value = 0.4) or chemo-resistance (p-value = 0.9). The presence of endometriosis did not significantly affect either OS or PFS. The median OS in the Ef-OCCC and Er-OCCC was 55.00 (95% CI 32.00-189.00) and 71.00 (95% CI 47.00-97.00; log rank = 1.35, p-value = 0.2) months. The median PFS in the Ef-OCCC and Er-OCCC group was 39.00 (95% CI 19.00-143.00) and 39.00 (95% CI 19.00-62.00; log rank = 0.7, p-value = 0.4) months. Survival differences between the two groups were not significant after stratification analysis for independent prognosticators. CONCLUSION: Endometriosis was not independently associated with the prognosis of OCCC either in crude analysis or after stratification for stage and RD. Further larger, well-designed prospective studies are warranted to draw firmer conclusions on the intrinsic link between endometriosis and OCCC.

BACKGROUND: Surgery is the cornerstone of gynecological cancer management, but inpatient treatment may expose both patients and healthcare staff to COVID-19 infections. Plans to mitigate the impact of the COVID-19 pandemic have been implemented widely, but few studies have evaluated the effectiveness of these plans in maintaining safe surgical care delivery. AIM: To evaluate the effects of mitigating plans implemented on the delivery of gynecological cancer surgery during the COVID-19 pandemic. METHODS: A comparative cohort study of patients treated in a high-volume tertiary gyneoncological centre in the United Kingdom. Prospectively-recorded consecutive operations performed and early peri-operative outcomes during the same calendar periods (January-August) in 2019 and 2020 were compared. RESULTS: In total, 585 operations were performed (296 in 2019; 289 in 2020). There was no significant difference in patient demographics. Types of surgery performed were different (p = 0.034), with fewer cytoreductive surgeries for ovarian cancer and laparoscopic procedures (p = 0.002) in 2020. There was no difference in intra-operative complication rates, critical care admission rates or length of stay. One patient had confirmed COVID-19 infection (0.4%). The 30-day post-operative complication rates were significantly higher in 2020 than in 2019 (58 [20.1%] versus 32 [10.8%]; p = 0.002) for both minor and major complications. This increase, primarily from March 2020 onwards, coincided with the first peak of the COVID-19 pandemic in the UK. CONCLUSIONS: Maintaining surgical throughput with meticulous and timely planning is feasible during the COVID-19 pandemic but this was associated with an increase in post-operative complications due to a multitude of reasons.
