RESULTS Prediagnosis use of metformin dose ≤1500 mg/d was associated with lower risk of death after HCC diagnosis in patients with T2DM (HR, 0.72; 95% CI, 0.58-0.91), adjusting for postdiagnosis metformin dose, diabetes severity, Charlson comorbidity index, tumor characteristics, and other relevant factors. No association was found for prediagnosis metformin dose >1500 mg/d or postdiagnosis metformin use. Further, no association was found for either prediagnosis or postdiagnosis statins use. CONCLUSIONS Prediagnosis use of metformin dose ≤1500 mg/d is associated with longer overall survival of elderly diabetic HCC patients.This letter to the Editor aims to provide suggestions and recommendations for the management of urological conditions in times of COVID-19 crisis in Brazil and other low- and middle-income countries. It is important to highlight that one of the main characteristics of this pandemic is the oversaturation of the health system capacity, mostly due to a high demand for personal protective equipment (PPE), Hospital/ICU beds, as well as ventilators. In places with limited resources and where the health care systems are already saturated, such consideration is even more worrisome. Therefore, most worldwide authorities are recommending to avoid, as much as possible, patient's elective visits to hospitals, as well as a judicious use of the operating room in order to mitigate the strain put on the health system. While efforts should be directed to the care of COVID-19 patients, other conditions (especially urgencies and oncological cases) must continue to be assisted. Thus, through a panel of experts, we have prepared a practical guide for urologists based on the recommendations from the main Urologic Associations, as well as data from the literature to support
