Surface Guided Radiation Therapy

From EverybodyWiki Bios & Wiki








Surface Guided Radiation Therapy (SGRT) is a non-invasive method for positioning radiation therapy patients, based on surface reconstruction using optical 3D imaging.[1] From early publications in 2003[2], it is now becoming a routine tool for patient positioning in many radiation therapy clinics[3].

SGRT enables a reduction of initial setup variability, provides verification of patient position continuously during treatment, and provides surface information for use in gated and breath-hold treatment techniques, all of which can permit reductions in the margins required to account for target localization uncertainty[4]. Additionally, surface imaging enables immobilization techniques that give greater comfort to patients, a reduction in imaging dose through reduced radiographic localization requirements, and improvements to the speed, efficiency, and safety of clinical workflows[4].

Specific applications for SGRT include treatment of locations including lung[5], breast[6], (including heart-sparing treatments[7]), brain (including stereotactic treatments)[8], pelvis[9], and extremities[10].

SGRT in breast radiotherapy.

Darby et al 2013, showed that treating breast cancer with radiotherapy results in an increase of major coronary effects in the following years for the surviving women[11] limiting radiation exposure to healthy vital organs. [12] Research indicates around three-quarters of patients with left-breast cancer have better radiation dose distribution if DIBH is used.[13]

DIBH with SGRT involves the method of free-breathing breath-hold, while optical technology tracks the skin surface position of breath-hold to determine when the patient has moved into the correct position. This has been shown to be accurate[14] and reproducible[15].

Research suggests that the use of SGRT for monitoring DIBH is successful in reducing or eliminating radiation damage to the heart.[16]

SGRT as a substitute for patient tattoos / marks

Radiation therapy tattoos are often used for treatment localization and may have long-term psychological impact on some patients[17]. SGRT has been studied as a potential means to avoid marks or permanent tattoos for localization of radiation therapy, delivering equivalent or better accuracy versus the older techniques[18] [19] reduced time requirements[20] [21] and reduced use of X-ray imaging.[21] Some radiation therapy treatment centers now offer “tattooless” treatment[22] through the use of SGRT.

SGRT in Stereotactic Radiosurgery / Radiotherapy (SRS)

After initial localization with IGRT, SGRT technology uses the visible portion of the patient’s surface (face) to track patient motion throughout treatment. The accuracy of this technique has been found to be sufficient for stereotactic treatments[23][24][25][26][27][28][29][30]. This technique is reported to have greater patient comfort with clinical outcomes comparable to those with conventional frame-based and frameless stereotactic radiosurgery techniques[31][32], Additionally, a recent study suggests that SGRT can be used in place of scheduled mid-treatment X-ray based localisation.[33]

SGRT-assisted SBRT (stereotactic body radiation therapy)

SBRT requires high positioning accuracy and monitoring and SGRT has been shown to provide a reliable real-time, non-invasive and non-ionizing option to monitor the patient continuously with high accuracy and precision.[34]

SGRT in Sarcoma treatment

Owing to their mobility, positioning limbs for treatment can be difficult, necessitating large treatment margins[35]. Whilst soft-tissue sarcomas are relatively rare, they are challenging for setup. Published data suggests that SGRT improves the setup accuracy.[36]

For radiation therapy in children, SGRT offers additional information to correct patient positioning errors before pre-treatment X-Ray[37] and has reduced the need for anaesthesia. [38]
