The number of surgical interventions in an outpatient clinic setting has continuously increased. An important advantage of such approach is the low infection rate. From an economic point of view, this setting leads to lower costs and, subsequently, lower charges to the health insurance companies according to the today's contracts. However, an essential prediction for surgical interventions in an outpatient clinic setting is that there is no increased risk compared with interventions of hospitalized patients. Taking this in consideration, we conclude that the very specific onco-surgical interventions can only be executed in a hospital setting because of their risk profile and the characteristics of tumor patients.
