Item How Do Breast Cancer Patients Present Following COVID-19 Early Peak in a Breast Cancer Center in Turkey?(GALENOS YAYINCILIK, 2021-01-01) Isiklar, Aysun Dauti; Deniz, Cem; Soyder, Aykut; Guldogan, Nilgun; Yilmaz, Ebru; Basaran, GulObjective: Coronavirus disease 2019 (COVID-19) has placed an unprecedented burden on healthcare systems and restricted resources for non-COVID patients worldwide. Treatment approaches and follow-up plans have been modified to prevent the risk of infection for patients and healthcare workers. Patients prefer to delay or cancel their treatments during the peak period of infection. Materials and Methods: We retrospectively reviewed the characteristics of patients with breast cancer who were consulted at our outpatient clinic right after early COVID-19 peak in May and June 2020 and compared them with the same period in 2017 to 2019. Results: The number of patients who consulted at our outpatient medical oncology clinic declined in May and June 2020. This decline was regardless of stage and was larger in May than in June 2020. In general, the distribution of tumor subtypes {[}luminal, human epidermal growth factor receptor 2 (HER-2) positive, and triple negative] was not different from 2017 to 2020. Less than half of the patients received adjuvant chemotherapy following early COVID-19 peak in May and June 2020. Few patients received chemotherapy for metastatic disease, whereas many metastatic patients received endocrine therapy. None of the consulted new patients had a non-invasive disease. More patients received endocrine therapy than chemotherapy. Conclusion: The presentation patterns of patients with breast cancer after early COVID-19 peak differed from those during the same period in the last 3 years. The pandemic affected the number of new patients consulted and the way medical oncologists treat their patients.Item What Has Changed in Patients Aged 65 and over Diagnosed with Breast Cancer during the COVID-19 Pandemic: A Single-Center Experience(KARGER, 2022-01-01) Soyder, Aykut; Guldogan, Nilgun; Isiklar, Aysun; Aribal, Erkin; Basaran, GulIntroduction: The COVID-19 pandemic has a worldwide negative impact on healthcare systems. This study aims to determine how the diagnosis, clinicopathological features, and treatment approaches of patients with breast cancer (BC) diagnosed at >= 65 years old were affected during the pandemic. This survey has shown that patients, especially the elderly, had to postpone their BC health problems or delay their routine controls due to the risk of COVID-19 transmission, high mortality rates due to comorbidity, and restrictions. Materials and Methods: The medical records of 153 patients with BC diagnosed at >= 65 years old before (January-December 2019Item Three Cases of Breast Metastases from Lung Cancer and Systematic Review of the Literature(GALENOS YAYINCILIK, 2021-01-01) Guldogan, Nilgun; Icten, Gul Esen; Tokat, Fatma; Tutar, Burcin; Kara, Halil; Korkmaz, Taner; Uluc, Basak Oyan; Demir, GokhanDespite the high prevalence of lung cancer among other primary tumors, metastasis of this particular malignancy in the breast is very rare. We report three new cases of lung cancer with breast metastases and discuss radiological and clinical findings. Radiologically, each case displayed different characteristics. First, one of them had bilateral superficially and deeply located irregular lesions. Second, the patient presented with findings similar to inflammatory breast cancer. The third case had a circumscribed mass, resembling a benign complicated cyst. To guide clinicians for proper patient management, radiologists should be aware of the scope of typical and atypical imaging findings of metastatic involvement of the breast.Item The effect of COVID-19 pandemic on breast imaging: a clinical observations(TURKISH SOC RADIOLOGY, 2020-01-01) Yilmaz, Ebru; Guldogan, Nilgun; Aribal, Erkin
