Among 85 patients with a suspicion of regional lymph node metastases on FCH PET/CT only 31 had pathology-proven metastases. The sensitivity was 43% (95% CI 0.32-0.55) and the specificity 70% (95% CI 0.63-0.76) for PET/CT to predict lymph node metastases. PPV was 36% and NPV was 75%. Risk group analyses showed similar results. Our study emphasizes the poor performance of FCH PET/CT to predict lymph node metastasis in intermediate and high-risk prostate cancer. The method should be replaced with newer radiopharmaceuticals, such as prostate-specific membrane antigen ligands.

Splenectomy is a common surgical procedure, and splenectomized patients have shown to be severely more affected by certain infections than patients with a preserved splenic function. We investigated the risk of COVID-19 infection and subsequent hospitalisation and death in splenectomized patients. We conducted a case-control study of all individuals with a microbiologically verified COVID-19 infection in Denmark through December 31, 2020. To each case, we matched three controls on age, sex, and region of residence. We examined the association between previous splenectomy and the risk of COVID-19 infection, hospitalisation, and death using a logistic regression model. We identified 165,623 individuals with a positive COVID-19 test and 493,300 matched controls. Mean age was 38 years. 130 and 422 splenectomies were performed in the COVID-19 positive individuals and controls, respectively. Splenectomized patients did not have a higher risk of COVID-19 infection than non-splenectomized patients (adjusted OR 0.89; 95% CI 0.73-1.08). Amon
