Outcome measures
Primary outcome
Detection rate of microbubble-enhanced Iodine-125 seed localization of SLN, defined as the number of patients in whom the microbubble-enhanced SLN and the Tc-99m enhanced SNL are the same.
Secondary outcome
1. Sensitivity of microbubble-enhanced I-125 seed localization;
2. Technical feasibility: visualization of SLN, successful I-125 seed placement and excision of I-125 seed without migration or seed loss;
3. Preoperative concordance of microbubble and Tc-99m enhanced SLNs, imaged with SPECT/CT;
4. Duration of procedures and hospitalization;
5. Patients pain and comfort scores: Microbubble-enhanced versus Tc-99m guided localization of SLN;
6. Surgeon’s / radiologists preferences and opinions.
Background summary
Preoperative work-up for breast surgery and sentinel lymph node (SLN) biopsy is logistically complicated. On the day of surgery, patients spend hours at imaging departments and operating theatres are forced to keep flexible time schedules. Microbubble-enhanced Iodine-125 seed localization has the potential to allow localization of the SLN days or weeks before surgery. With the current study, we aim to evaluate whether microbubble localization of the SLN is a reliable alternative for the standard technetium-99m enhanced SLN localization and subsequent SLN biopsy. If the microbubble technique turns out to be an accurate alternative, logistics and waiting time on the day of surgery will be improved, which would be of great benefit for the patient.
Study objective
Contrast-enhanced ultrasound with microbubbles will localize the same axillary lymph node as Technetium-99m nanocolloid.
Study design
SLN localization with microbubbles, Iodine-125 seed placement and SPECT/CT scan.
Intervention
Preoperative contrast-enhanced ulterasound with microbubble contrast for localization of axillary lymph node(s) localization with subsequent placement of an Iodine-125 seed will be compared to 'standard sentinel lymph node localization'. Both techniques will be applied in all study patients.
