Our Results

Proven Outcomes. Delivered with Precision.

Capital Radiosurgery Centers SBRT programs are built around long-term cancer control, reduced toxicity, and fewer disruptions to patients’ lives. Outcomes are supported by multi-year clinical data and align with national standards of care.

SBRT with CyberKnife

High Long-Term Cancer Control

Published studies report five-year control rates approaching 98%, placing SBRT among the most effective non-surgical treatments for localized prostate cancer.

Comparable to Surgery, Without the Burden

Ten-year outcome data shows SBRT achieves similar disease control to prostatectomy, while avoiding surgery, hospitalization, and extended recovery. Treatment is typically completed in five sessions.

Lower Toxicity, Better Quality of Life

Compared with longer radiation courses, SBRT is associated with:

  • Fewer bowel and sexual side effects
  • Short-term urinary symptoms that typically resolve
  • Faster return to normal daily activities

Clinical Overview

  • Dose: 40 Gy delivered in 5 fractions

  • NCCN-approved for low, intermediate, and high-risk prostate cancer

  • SBRT used in ~90% of nonmetastatic prostate cases

Why It Matters

  • Fewer treatments with less urinary and bowel toxicity

  • Cancer control equal to or better than IMRT

  • Treatment completed in one week or less

Operational Strength

  • 16 patients were treated in an 8-hour day

  • Capacity to treat 800+ patients per year per CyberKnife

SBRT & APBI After Lumpectomy

Equivalent Cancer Control, Less Toxicity

Ten-year randomized trials show accelerated partial breast irradiation (APBI) provides the same cancer control as whole-breast radiation for appropriately selected patients—with fewer side effects.

More Targeted Treatment

By treating only the tumor bed plus margin, SBRT:

  • Reduces exposure to healthy breast tissue
  • Shortens treatment from weeks to days
  • Improves long-term cosmetic outcomes

CRC Clinical Practice

  • DCIS and Stage I disease post-lumpectomy
  • 30 Gy in 5 fractions
  • NCCN-supported treatment approach

SBRT: One Week

3D: 3-6 weeks

Clinical Overview
  • Technique: APBI (Accelerated Partial Breast Irradiation)

  • Dose: 30 Gy in 5 fractions

  • Criteria: ≤3 cm tumor, node-negative, negative margins

Evidence-Based Outcomes

  • 10-year randomized trials show:

    • Same cancer control as whole-breast radiation

    • Less toxicity and improved outcomes

  • NCCN-supported treatment option

Why Patients Prefer It

  • Targets only the tumor bed (+1 cm margin)

  • Avoids weeks of whole-breast radiation

  • Faster recovery, fewer side effects

Lung Cancer Results

SBRT for Early-Stage & Recurrent Disease

Excellent Local Tumor Control

SBRT achieves over 90% local control at three years for early-stage non-small cell lung cancer—on par with surgical outcomes.

Comparable to Surgery for Early-Stage Disease

Long-term (10-year) data shows SBRT outcomes comparable to surgery for early-stage lung cancer, with:

  • Fewer acute side effects
  • No incisions or hospital stay
  • Preserved lung function

Standard of Care for Medically Inoperable Patients

SBRT is widely recognized as the standard of care for patients who cannot undergo surgery, and is increasingly used even when surgery is an option.

SBRT: One Week

3D: 3-6 weeks

Clinical Overview

  • Stage I lung cancer now represents ~50% of cases treated

  • SBRT is standard of care for early-stage, medically inoperable patients

  • Typical course: 3–5 fractions

Expanded Applications

  • Solitary lung metastases: 3–5 fraction SBRT

  • Recurrent lung disease: SBRT retreatment options

  • Stage III disease: IMRT/3D ± chemotherapy (30 fractions)

Why This Is a Shift

  • Earlier detection via low-dose CT screening

  • SBRT enables curative intent without surgery

  • Shorter treatment course with durable control

What patients are saying:

“You have made such a change in a short time. I thank you for your kindness and gentle ways of helping someone that was in such discomfort.”
