Priority category Clinical conditions Consult to decision-to-treat* Ready-to-treat to operation

P2 Patients diagnosed with very aggressive tumours, such as central nervous system (CNS) cancer 14 14

  1. *From the date of the patient’s first visit to the operating surgeon for this specific problem until the decision-to-treat date. The decision-to-treat date is the date on which sufficient pre-treatment testing is complete, the physician can reasonably assume that the patient will be treated, and the patient has agreed to the treatment. By this date, sufficient assessment will have been completed in order to reasonably assume that the procedure will go ahead, and an operating room booking is requested.
