Summary

The Moldcare® cushion (M-Encompass) mask is a safe alternative for stereotactic brain radiotherapy, showing no significant differences in patient comfort or intrafractional motion compared to the Dual Shell Encompass Fibreplast™ System (DS-Encompass). Both systems demonstrate clinically irrelevant interfractional motion.

Area of Science:

  • Radiation Oncology
  • Medical Physics
  • Neurosurgery

Background:

  • Frameless immobilization is crucial for stereotactic brain radiotherapy.
  • The Dual Shell Encompass Fibreplast™ System (DS-Encompass) is validated for this purpose.
  • An alternative mask, M-Encompass, replaces the rear shell with a Moldcare® cushion.

Purpose of the Study:

  • To validate the M-Encompass mask in cranial stereotactic workflows, including HyperArc™.
  • To compare inter- and intrafractional motion between DS-Encompass and M-Encompass.
  • To assess patient comfort with both immobilization systems.

Main Methods:

  • A prospective randomized study involving 60 participants compared DS-Encompass and M-Encompass.
  • Treatment plans utilized HyperArc™ with surface guidance for patient positioning.
  • Interfractional motion was corrected via daily CBCT, and intrafractional motion was quantified post-treatment.
  • Patient comfort was assessed using a Likert scale.

Main Results:

  • No significant difference in interfractional translations was observed.
  • DS-Encompass showed significantly smaller roll-axis rotation deviations, deemed clinically irrelevant due to daily corrections.
  • Intrafractional motion remained below 0.5 mm and 0.5° for both systems, with no significant difference.
  • Patient-reported comfort levels were statistically similar between the two mask types.

Conclusions:

  • The M-Encompass system offers a safe and effective alternative to DS-Encompass for non-coplanar stereotactic brain radiotherapy.
  • Both systems provide comparable intrafractional motion control and patient comfort.
  • The study supports the use of M-Encompass in advanced stereotactic treatment protocols.
