- Brief Summary
This study is a single-center prospective, randomized and quasi double blinded pilot study. The study has 2 parallel arms, each arm involved around 54 patients. Targeted community is the newly diagnosed adults with non metastatic and non inflammatory breast cancer in King Hussein Cancer Center who require axillary biopsy as part of their staging work up. The study aims to improve the intra-operative identification of the preoperatively suspicious and biopsied lymph nodes and test the concordance between the pre-operative clinical suspicion and histopathological results of these node; by comparing between preoperative marking of biopsied axillary lymph nodes with two different modalities (clipping Vs tattooing) and testing its concordance with sentinel lymph node biopsy, both in upfront surgery and neoadjuvant chemotherapy settings and in a prospective, randomized and quasi double blinded design
- Detailed Description
This study is a single-center prospective, randomized and quasi double blinded pilot study. The study will enclose 2 parallel arms, each arm will involve 54 patients (total 108 patients), comparing between preoperative marking of biopsied axillary lymph nodes with two different modalities (clipping Vs tattooing) and testing its concordance with sentinel lymph node biopsy, both in upfront surgery and neoadjuvant chemotherapy settings and in a prospective, randomized and quasi double blinded design.
Targeted community is the newly diagnosed adults (more than 18 years of age) with non metastatic and non inflammatory breast cancer in King Hussein Cancer Center who require axillary biopsy as part of their staging work up.
The standards of breast cancer care in KHCC state that all patients are required to do breast and axillary staging via clinical examination and imaging (mammogram and U/S), and require any patient with clinically suspicious axillary lymph node/nodes to undergo U/S guided axillary biopsy. Patients with negative axillary biopsy will require axillary sentinel lymph node biopsy and patients having positive axillary lymph node biopsy will require axillary clearance along with their standard breast cancer surgical treatment.
Once the need for axillary biopsy is defined, the patients offered to participate in the study in a proper environment and their consent was gained after their approval. Participants were given another appointment few days later to obtain the axillary biopsy (as per the routine in the KHCC Breast Imaging Unit) and to mark the biopsied axillary lymph node in the same session, and on that day consented participants were randomized to either axillary lymph node clip placement or tattooing after obtaining the intended axillary biopsy.
Depending on the results of the biopsy, the KHCC breast MDC decided on the surgical management including the axillary treatment, the latter will be either sentinel lymph node biopsy (SLNBx)or axillary lymph node dissection (ALND). SLNBx will be performed on all recruited patients and to be followed by the standard axillary treatment as approved by KHCC clinical practice guidelines (either SLNBx alone or SLNBx followed by ALND). The group of patients with preoperative diagnosis of positive axillary nodes with undergo SLNBx as an extra procedure to test the study hypothesis and to be followed by ALND as per the KHCC protocol. The presence of the marking material will be confirmed prior to sending the SLNBx to the pathology department (by visualization of the tattoo and by X-ray examination of SLNBx looking for the clip). Patients whom receive ALND will have the presence of marking material checked in their specimens as well. This trial will study the concordance of both marking modalities with SLNBx identification

- Primary Outcome Measures
Name Time Method comparing effectiveness of tattooing versus clipping in SLNBx identification in breast cancer patients in upfront surgery setting, by comparing no. of identified positive or negative intraoperative SLN that were marked with tattooing versus clipping 3 years To compare the effectiveness of tattooing compared to clipping in SLNBx identification in breast cancer patients in the upfront surgery and neoadjuvant setting, by comparing the number of identified positive or negative intraoperative SLN that were marked with the tattooing technique with the clip technique
- Secondary Outcome Measures
Name Time Method convenience for surgeon to perform SLNBx after lymph node marking from time & technical perspectives by comparing time and ease to identify the marked lymph nodes during surgery using a questionnaire completed by surgeons after each surgery 3 years The convenience for the surgeon to perform the SLNBx after the lymph node marking from time and technical perspectives by comparing the time and ease to identify the marked lymph nodes during the surgery using a questionnaire completed by surgeons after each surgery
convenience for radiologist to apply clip or tattoo from time and technical perspectives by comparing time spent in applying clip or tattoo and convenience of the application using a questionnaire completed by radiologists after each application 3 years The convenience for the radiologist to apply the clip or tattoo from time and technical perspectives by comparing time spent in applying the clip and tattoo as well as convenience of the application using a questionnaire completed by radiologists after each application
