Acibadem Maslak Hospital is the largest hospital in the Acibadem Healthcare Group network, opened in 2009 in Sarıyer (Istanbul). After its expansion in 2018, the clinic occupies 106,000 m² and has 248–288 rooms, 20 operating rooms, and 27 ICU beds. JCI accreditation and LEED Gold certificate.
For oncology patients who need radiation therapy, Acibadem Maslak is one of the strongest addresses in Turkey.
Since 2009, the CyberKnife robotic radiosurgery system has been operating here — this allows precise treatment of tumors of the brain, lungs, liver, prostate, and other cases where conventional surgery is risky.
The clinic was also the first in Turkey to use volumetric modulated arc therapy (VMAT) and widely uses image-guided IMRT (IGRT), MR-guided radiation therapy (MR-Linac), and stereotactic body radiation therapy (SBRT).
