BackgroundWe compared the new outpatient clinic referrals during the first 10 months of the COVID-19 pandemic with the year before.MethodsWe compared baseline characteristics of the 2208 new referrals in 2020 (n=922) and 2019 (n=1286) with Χ2and Mann-Whitney U tests and calculated ORs with binary logistic regression. To evaluate the expected changes in the cancer survival secondary to stage migration, we used the 5-year survival data of Survival, Epidemiology and End Results (SEER) Program 2010–2016.ResultsThe percentage of patients with inoperable or metastatic disease was significantly increased during the pandemic (49.8% vs 39%, OR: 1.553, 95% CI: 1.309 to 1.843, p<0.001). We observed a significant decrease in the percentage of patients diagnosed via the screening methods (18.8% vs 28.7%, OR: 1.698, 95% CI: 1.240 to 2.325, p=0.001). The 90-day mortality after the cancer diagnosis was significantly higher during the pandemic (10.5% vs 6.6%, OR: 1.661, 95% CI: 1.225 to 2.252, p=0.001). Due to the increased advanced-stage disease rate at first referral, significant decreases in 5-year survival rates were expected for breast cancer (−8.9%), colorectal cancer (−11.1%), cervix cancer (−10.3%) and melanoma (−7%).ConclusionWe think that collaborative efforts are paramount to prevent the pandemic of late cancer diagnoses and ensure patient safety during the pandemic.

BackgroundCOVID-19 pandemic could create a collateral damage to cancer care denoting disruptions in care due to a significant burden on healthcare and resource allocations. Herein, we evaluate the early changes in the inpatient and outpatient oncology clinics to take a snapshot of this collateral damage at Hacettepe University Cancer Institute.MethodsPatients applying the outpatient clinic and outpatient palliative care (OPC) clinic for the first time and patients admitted to inpatient wards in the first 30 days after the first case of COVID-19 in Turkey were evaluated. These data were compared with data from the same time frame in the previous 3 years.ResultsThe mean number of daily new patient applications to the outpatient clinic (9.87±3.87 vs 6.43±4.03, p<0.001) and OPC clinic (3.87±1.49 vs 1.13±1.46, p<0.001) was significantly reduced compared with the previous years. While the number of inpatient admissions was similar for a month frame, the median duration of hospitalisation was significantly reduced. The frequency of hospitalisations for chemotherapy was higher than in previous years (p<0.001). By comparison, the rate of hospitalisations for palliative care (p=0.028) or elective interventional procedures (p=0.001) was significantly reduced.ConclusionIn our experience, almost all domains of care were affected during the pandemic other than patients’ systemic treatments. There were significant drops in the numbers of newly diagnosed patients, patients having interventional procedures and palliative care services, and these problems should be the focus points for the risk mitigation efforts for prevention of care disruptions.
