Outcome measures
Primary outcome
To evaluate the effectiveness of Indocyanine Green (ICG) for sentinel lymph
biopsies in breast cancer patients.
Secondary outcome
Secondary Objectives:
To assess:
- The median number of SLN identified
- Percentage of SLNs that has 99mTc uptake/ is fluorescent
- The pathology of SLNs found by localization method, including micro- and
macro metastases and isolated tumor cells (ITCs)
- The detection time, defined as time between skin incision and SLN resection
in minutes
- Duration of the SN-procedure
- Duration of the total surgical procedure
- Complications, including seroma, wound infection and bleeding
- The number of serious adverse events
- Duration of the total procedure
- Locoregional recurrence after 1 year follow-up
To describe:
- (Pre-implementation) expectations regarding ICG
- (Post-implementation) experiences regarding ICG including success factors and
barriers.
- The process of the learning curve
To provide:
- National guidelines for ICG implementation
Background summary
Identifying lymphatic metastases is an important prognostic factor in the
survival rate of breast cancer and the presence of lymphatic metastases carries
consequences for further treatment. The golden standard for obtaining the SLN
in patients with breast cancer is radioguided surgery with radioisotope
technetium (99mTc). However, the use of 99mTc may present adverse effects and
is logistical challenging. An alternative method is fluorescence imaging using
Indocyanine Green (ICG).A recently published study (INFLUENCE trial) showed
that ICG is a safe and effective method for SLN mapping in breast cancer
patients with equal detection rates compared to Technetium.
Study objective
The objective of this study is to evaluate the (nationwide and international)
implementation of ICG-fluorescence for SN-procedures for patients with breast
cancer.
Study design
The INFLUENCE-II study is a (national and international) multicenter,
prospective, pre-post implementation study describing the implementation of
Indocyanine Green fluorescence imaging for SLN mapping in patients with breast
cancer.
Intervention
Phase I (pre-implementation)
The standard of care SLN procedure will be performed, which implies 99mTc
injection, the day or the morning before surgery. Study outcomes will be
registered during SN-procedures. Questionnaires regarding ICG-related
expectations will be collected.
Phase II (transition period)
In the transition period patients receive dual injection with both
99mTc-nanocolloid and ICG. Workshops and hands-on courses will be provided by
initiating hospital. No study-related registrations during SN procedures in
this phase are performed. Surgeons register the number of dual procedures
needed to proceed to the use of ICG alone.
Phase III (post-implementation)
The SN-procedure is performed with the use of ICG as single tracer. Study
outcomes will be registered during SN-procedures. Questionnaires regarding
ICG-related experiences will be collected.
