What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests a device called SAVI Scout, which helps surgeons locate and remove breast tumors more precisely. The device, already approved for use, uses infrared light to guide the surgeon to the tumor. The trial seeks individuals with specific types of breast cancer, particularly those with a single tumor confirmed through imaging or biopsy. Participants should not have a nickel allergy or certain medical implants. This trial may suit those undergoing treatment for breast cancer who meet these criteria. As an Early Phase 1 trial, the research focuses on understanding how the SAVI Scout device functions in people, offering participants the chance to contribute to advancements in surgical precision for breast cancer treatment.

Do I need to stop my current medications for this trial?

The trial protocol does not specify if you need to stop taking your current medications. However, if you have active cardiac implants, you cannot participate.

What prior data suggests that the SAVI Scout device is safe for breast lesion localization?

Research has shown that the SAVI Scout system, approved by the FDA since 2014, is safe. In 2017, the FDA approved it for long-term use without time limits, further confirming its safety.

Doctors use this system in surgeries like lumpectomies to remove breast cancer lumps. Studies indicate that it helps doctors locate and remove tumors more accurately, leading to better outcomes. Although specific safety statistics aren't mentioned, this information suggests patients generally tolerate it well.

In summary, the SAVI Scout system has been safely used in many procedures since its approval, indicating a strong safety record in humans. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Unlike traditional methods for locating breast tumors, which often rely on wire localization techniques, the SAVI Scout® system is unique because it uses a radar-based localization method. This system allows for more precise placement of a marker within the breast tumor, which can improve surgical accuracy and potentially lead to better outcomes for patients. Researchers are excited about this approach because it offers a less invasive, more comfortable experience for patients and could reduce the time spent in surgery, enhancing overall treatment efficacy and patient satisfaction.

What evidence suggests that the SAVI Scout device is effective for breast lesions?

Research has shown that the SAVI Scout system, which participants in this trial will receive, effectively locates breast lumps. Studies have demonstrated a success rate of over 99% for both placing and retrieving the marker used in this system. One study found that the system helped surgeons completely remove breast lumps, including cancerous ones, without requiring additional surgery. The technology uses infrared light and radar signals to guide surgeons precisely to the lump, facilitating accurate removal. This evidence supports the idea that SAVI Scout can effectively assist in breast surgeries by improving accuracy and reducing the need for follow-up procedures. ^{1 6 7 8 9}

In a study of 12,776 women aged 67-94 with ductal carcinoma in situ (DCIS) who underwent breast-conserving surgery, sentinel lymph node biopsy (SLNB) did not show any significant improvement in long-term outcomes such as treated recurrence, ipsilateral invasive occurrence, or breast cancer mortality compared to those who did not undergo SLNB.

The results suggest that routine SLNB may not be necessary for older patients with DCIS, as it did not provide additional benefits in terms of cancer recurrence or survival rates.
