2021por Lovo, Eduardo E, Barahona, Kaory C, Campos, Fidel, Caceros, Victor, Tobar, Carlos, Reyes, William A“…Single-session stereotactic radiosurgery (SRS) might not provide an adequate dose for long-term local control due to the initial tumor volume and the involvement of radiation sensitive organs at risk (OARs). Two-session radiosurgery has been described as a feasible strategy for dose escalation in large secondary brain tumors. …”
