ABSTRACT
Background: The COVID-19 pandemic influenced patient health care decisions, but there is little information about the pandemic's impact on decisions about cancer risk reduction. This includes women at elevated risk of breast or ovarian cancer considering risk-reducing salpingooophorectomy (RRSO), risk-reducing salpingectomy (RRS), or other preventive measures. During the pandemic patients needed to balance their concerns about cancer risk reduction with their risks associated with elective health procedures, a risk which changed as vaccines became available. Method(s): To address the impact of the COVID-19 pandemic on cancer prevention decision making, we recruited N=396 pre-menopausal women with a personal history of breast cancer or familial history suggestive of increased breast and/or ovarian cancer risk between 4/2019 and 3/2022. We conducted a discrete choice experiment in which patients were asked to choose between two scenarios that specified type of surgery (RRSO, RRS vs. non-surgical surveillance), age of menopause (natural versus immediate), quality of menopausal symptoms (mild, moderate, severe), and risk of ovarian cancer, heart disease, or osteoporosis. Risk of ovarian cancer for the scenarios provided varied in discrete intervals from 0% to 40%. We examined temporal trends during the pandemic using interactions with time coinciding approximately with the beginning of pandemic, peak vaccination period, and the Omicron wave. Result(s): We identified significant temporal interactions on a woman's prevention decisions. In 2019, women at higher risk of ovarian cancer were more likely to choose prevention scenarios that favored lower ovarian cancer risk (odds ratio [OR] = 0.48;95% CI = 0.37, 0.69 per 10% increase in ovarian cancer risk difference). This association decreased through the pre-vaccine period of 2020 by OR=2.61/month (95% CI = 1.21, 5.65). By June 2020, the effect of a 10% increase in ovarian cancer risk on intervention choice had attenuated substantially (OR=0.84, 95% CI 0.67, 1.00). By January 2022, the effect strengthened (OR= 0.69, 95% CI .49, .88), but had not reached pre-pandemic levels. Before 3/2020, natural age of menopause (versus immediate) had a strong impact on the choice of a scenario (OR=3.56, 95% CI 1.65-7.65). At the beginning of the pandemic, the effect was reduced by 0.47/month (95% CI 0.22-0.99). The rate of attenuation slowed over time, such that the effect of having a natural age of menopause on choice was OR= 1.56 (95% CI 0.65, 2.46) by January 2022. Tests for temporal interactions were statistically significant for both ovarian cancer risk and age of menopause. Conclusion(s): Our results suggest that over the course of the pandemic, women seemed more accepting of higher risks of ovarian cancer and immediate (post treatment) menopause when considering preventive options. There was an inverse U shape curve of the effect of ovarian cancer risk on choices over time (Figure A), but the strength of the relationship had not reached prepandemic levels by January 2022. This may reflect patient tolerance for side effects as the pandemic evolved. These results suggest that factors such as ovarian cancer risk and delay of menopause influenced personal prevention choices, but that these choices were influenced by events related to events that hallmarked the COVID-19 pandemic.
ABSTRACT
Background: The COVID-19 pandemic has been associated with a significant disruption in healthcare services including cancer screening and diagnosis. Delays in cancer screening and treatment may lead to increased mortality. We aimed to analyze changes in screening, diagnosis and surgical treatment of common GU malignancies in relation to the COVID-19 pandemic. Methods: We evaluated screening, novel diagnoses, and surgical management modalities of prostate cancer (PCa), urothelial carcinoma (UC) and renal cell carcinoma (RCC) within Massachusetts General Brigham, the largest healthcare system in the Northeastern United States, over four 3-month time periods during the pandemic (March 2020- March 2021). The percentage change in screening, diagnoses and management modalities during pandemic periods as compared to the immediate pre-pandemic period (December 2019-March 2020) was calculated as (Nperiod - Ncontrol)/Ncontrol. The difference in "predicted" versus "observed" diagnoses in each pandemic period was compared to the average of the four preceding 3-month periods (March 2019-March 2020) to account for seasonal variation. Results: The first pandemic peak (March-June 2020) was associated with a significant decline across screening, diagnosis and treatment, ranging from -15.7 to -64.8%, followed by a progressive recovery, ranging from -5.9 to +25.1% in the latest period (December 2020-March 2021) (Table). Although 725 diagnoses were "missed" between March and June 2020 as compared to the previous 12 months, 971 diagnoses were "recovered" between June 2020 and March 2021. Conclusions: A substantial disruption in the screening, diagnosis and treatment of GU malignancies was observed early in the pandemic, followed by a progressive rebound and recovery. The highest declines were observed for PSA screening, and the lowest for cystectomy procedures, reflecting triaging of care based on severity during the pandemic.
