Gynecology and cervical cancer brachytherapy

Why brachytherapy for GYN cancer treatment?

ESMO and ABS recommend the use of brachytherapy radiation therapy as an essential component of the definitive treatment of locally advanced cervical cancer (LACC) – 1, 2

Connectivity to MOSAIQ® OIS

Confidence for you and your patients

  • Contributes to paperless brachytherapy workflow information
  • Automated scheduling and billing process
  • Documented dose and structure sets
  • Automatically exchange treatment plans created with Oncentra Brachy and treatment records generated by the afterloader
  • Perform dose tracking based on the treatment plan and treatment record for the selected and verified patient
  • Provide a more efficient and electronic way to capture information that will be included in the patient’s Continuity of Care Document (CCD), data as required for meaningful use (Stage 1 and beyond)

Gynecological brachytherapy applicators

Broadest range of CT/MR compatible applicators

Our wide array of applicators for gynecological brachytherapy are available for many applications, ranging from intracavitary to interstitial use and designed to deliver increasingly more precise doses to kill cancer cells in gynecologic brachytherapy.

“With Venezia, I expect to treat advanced cervical cancer patients with more ease. Venezia will allow me to reach tumors extended to the parametrium because I can position needles at multiple angles, in the vagina and through the perineum.”

Petch Alisanant, MD, Division of Radiation Oncology, Chulalongkorn University, Bangkok, Thailand

Venezia™

Advanced Gynecological Applicator

A new option for treating advanced stage cervical cancer

Venezia is an applicator system that will enable clinicians to easily reach the cervix, parametrium and vaginal extensions in stage IIIA and IIIB tumors. The female reproductive system has been difficult to reach with current brachytherapy techniques. Venezia enables physicians to treat locally advanced cervical cancers with interstitial brachytherapy in a pre-defined and reproducible way, ensuring optimal dose distribution for the majority of patients. Because of the one-click system Venezia is easy to insert and assemble, eliminating the need for screws or tools.

Geneva

Universal Gynecological Applicator - one applicator for most cervical cancer patients up to stage IIB

Easy to assemble and easy to insert, Geneva accommodates most female pelvic anatomies and is suitable for treating the majority of cervical cancer cases up to stage IIB. Offering distortion-free imaging and the option for guided interstitial brachytherapy with every configuration, Geneva provides unprecedented versatility without compromising ease of use and precision.

“The best case scenario is where you have the availability of ultrasound so that you can actually control the depth of the needles in real time as you're placing them.”

Oncentra Brachy

Comprehensive treatment planning software

Designing the optimal dose distribution can be a time-consuming job. The latest version of Oncentra Brachy offers a series of useful tools that simplify many repetitive tasks, such as contouring and reconstruction. Oncentra Brachy buys you time to focus on what counts: creating the optimal dose distribution.

Oncentra Brachy also helps you optimize treatment plan accuracy, providing easy navigation to any plane that offers the most relevant information per region of interest. Template solutions for repetitive tasks, such as the new Implant Modeling tool and the popular Applicator Modeling feature, help reduce implant reconstruction time. DVH presets and the ROI Catalog Manager can help improve accuracy and reproducibility of brachytherapy gynecology. Powerful inverse planning optimization automates volume-based planning, making the process fast and efficient.

Reduce implant reconstruction time

  • Instant applicator reconstruction in relation to anatomy
  • Contains the complete geometry of Elekta's gynecological applicators
  • Includes the measured source paths of ring applicators
  • Accounts for dose attenuation resulting from shielding during planning and shields are fully visible

Dose distribution calculated by ACE

  • Algorithm based on the TG-186 recommendations published by the AAPM workgroup in 2012
  • Discriminates between tissue, air and bone
  • Accounts for tissue heterogeneities, lack of backscatter from areas with no tissue, applicator attenuation and shielding

Implant modeling tool

  • Reconstruct multicatheter implants immediately
  • Drag & Drop 3D applicator geometry for accurate and fast reconstruction
  • Extra Coordinate System (ECS) allows quick and easy navigation to the correct plane views

Automatic dose optimization

IPSA

  • Paired with the Dwell Time Deviation Constraint (DTDC)
  • Limits high variation in dwell times

HIPO

  • Improves plan optimization with Dwell Time Gradient Restriction (DTGR)
  • Control high and low peaks in dwell times
  • Focus optimization where it is needed with needle locking

Treatment delivery

Safe, simple, intuitive brachytherapy workflow

Five simple features are the basis for the Flexitron way of working, introducing a new standard in treatment delivery

  • Standardized transfer lengths, less prone to human errors during reconstruction as there is only one indexer length.
  • Reference zero at entrance of applicator, no need to measure the distal tip.
  • Metric dwell position numbering, 1 mm step size in a treatment window of 400 mm.
  • Forward stepping results in a reproducible source positioning within 0,5mm accuracy
  • Intuitive user interface, smooth navigation saves time.

Why Flexitron?

  • Simple quality assurance
  • 40-channel option for large implants
  • Connected to major oncology systems such as MOSAIQ®
  • Safe investment with future upgrade potential
  • Available in either Iridium-192 or Cobalt-60*

* Not available in all countries.
