Overview
Veterinary oncologists lack accessible focused ultrasound treatment options for animal cancer patients, requiring expensive referrals to specialized centers that are often hundreds of miles away and cost $5,000-$15,000 per treatment series.
The Openwater Veterinary Oncology model leverages OpenLIFU technology to provide accessible, cost-effective focused ultrasound treatment for common animal cancers, starting with soft-tissue sarcomas in dogsβthe most common cancer type in companion animals.
Clinical Need
Companion animal cancer treatment faces significant accessibility barriers:
- Limited Access: Only 12 veterinary centers in North America offer focused ultrasound therapy
- High Cost: Treatment series costs $10,000-$15,000, prohibitive for most pet owners
- Geographic Barriers: Average travel distance to treatment center is 300+ miles
- Treatment Delays: Referral process takes 4-8 weeks, during which tumors progress
- Alternative Risks: Current options (surgery, radiation) have higher complication rates
Clinical Procedure
The OpenLIFU-based veterinary treatment protocol provides non-invasive tumor ablation with same-day discharge:
Pre-Treatment Imaging & Planning
CT or MRI imaging performed to map tumor location, size, and proximity to critical structures. Treatment planning software generates optimal acoustic window and energy delivery pattern. Planning time: 30-45 minutes.
Patient Preparation & Anesthesia
Patient placed under general anesthesia and positioned on treatment table. Treatment area shaved and acoustic coupling gel applied. Continuous vital sign monitoring established.
Real-time Targeting & Verification
OpenLIFU system uses integrated ultrasound imaging to confirm tumor targeting in real-time. Treatment plan adjusted if patient positioning has shifted. Target verification: 5-10 minutes.
Focused Ultrasound Ablation
Focused ultrasound energy delivered in controlled pulses to heat and ablate tumor tissue. Real-time temperature monitoring ensures safe thermal dose. Treatment duration: 20-60 minutes depending on tumor size.
Post-Treatment Recovery
Patient recovered from anesthesia with standard monitoring. No surgical incision means minimal post-procedure pain. Same-day discharge with oral pain medication. Follow-up imaging at 2 weeks, 6 weeks, and 3 months.
Technical Implementation
Treatment Parameters
- Frequency Range: 500 kHz - 1.5 MHz (optimized for tissue depth and targeting precision)
- Acoustic Power: 50-200W (adjusted based on tumor size and depth)
- Treatment Temperature: Target tissue 55-60Β°C for complete ablation
- Pulse Protocol: 10-30 second pulses with 30-60 second cooling periods
- Treatment Volume: 1-8 cm diameter tumors (expandable to larger with multiple focal points)
Safety Features
- Real-time MR Thermometry: Continuous temperature monitoring in treatment zone
- Acoustic Intensity Limits: Automatic power reduction if temperature exceeds safety threshold
- Near-field Protection: Acoustic pattern avoids skin and superficial tissue damage
- Critical Structure Avoidance: Treatment planning identifies and protects blood vessels, nerves
- Emergency Stop: Immediate shutdown capability if patient movement detected
Target Indications (Initial Phase)
- Primary Focus: Soft-tissue sarcomas in dogs (trunk, limbs)
- Tumor Size: 2-6 cm diameter
- Tumor Depth: 1-5 cm from skin surface
- Exclusions: Tumors near critical organs, metastatic disease, poor anesthesia candidates
Implementation Roadmap
Phase 1: Clinical Partnership & Protocol Design (Months 1-4)
Objective: Engage veterinary oncology clinic to co-design initial treatment protocols for soft-tissue sarcomas.
- Partner with 1-2 veterinary oncology specialists at university teaching hospital
- Review 50+ historical soft-tissue sarcoma cases to understand typical presentation
- Document current treatment workflows (surgery, radiation, chemotherapy)
- Define LIFU treatment protocol adapted from human oncology experience
- Establish patient selection criteria and safety protocols
- Obtain IACUC approval for clinical pilot study
Phase 2: System Adaptation & Preclinical Testing (Months 5-10)
Objective: Adapt OpenLIFU system for veterinary use and validate in tissue models.
- Design veterinary-specific positioning and restraint systems
- Develop acoustic transducers optimized for canine tissue properties
- Create treatment planning software with canine anatomical models
- Validate ablation accuracy in ex-vivo tissue and gel phantoms
- Conduct cadaver studies to refine positioning and targeting
- Perform safety testing with healthy animal subjects (n=5-10)
Phase 3: Clinical Pilot Study (Months 11-22)
Objective: Treat 20-30 dogs with soft-tissue sarcomas to demonstrate safety and preliminary efficacy.
- Recruit client-owned dogs meeting inclusion criteria
- Treat 20-30 patients with complete follow-up imaging and outcomes
- Document treatment safety: adverse events, complications
- Measure tumor response: complete ablation rate, local control
- Assess quality of life: pain scores, activity levels, owner satisfaction
- Compare outcomes to historical surgery/radiation controls
- Refine protocol based on early results
Phase 4: Multi-Center Validation (Months 23-36)
Objective: Expand to 3-5 veterinary centers for broader validation.
- Install systems at partner veterinary oncology clinics
- Train veterinary oncologists and technicians on system operation
- Treat 100+ patients across multiple sites
- Establish standardized reporting for outcomes database
- Pursue USDA approval for commercial veterinary device
- Develop business model for sustainable veterinary deployment
Expected Outcomes
Clinical Outcomes
- Complete tumor ablation rate: 75-85% (comparable to surgery)
- Local tumor control at 1 year: 65-75%
- Complication rate <10% (vs. 25-30% for surgery)
- Same-day discharge for 95%+ of patients
- Return to normal activity within 3-5 days
Economic Outcomes
- Treatment cost: $2,000-$3,500 (vs. $10,000+ for referral)
- 70% cost reduction vs. current specialized centers
- Eliminate travel costs averaging $1,000-$2,000 per case
- Enable treatment access for 10x more pet owners
Accessibility Outcomes
- Bring advanced cancer treatment to community veterinary practices
- Reduce treatment timeline from 4-8 weeks (referral) to 1-2 weeks (local)
- Enable second opinions and retreatment without multi-state travel
- Support veterinarians in providing comprehensive oncology care
