I want to find patients with a diagnosis of malignant neoplasm of the prostate and an elevated prostate specific antigen (PSA) level, with a specificity scale of 0 and any timing, and display the results in a panel with a total of 2 items, including the diagnosis of malignant neoplasm of the prostate and the elevated PSA level as separate items.
