SCOUT Reflector for Tagging Lymph Nodes for Targeted Removal in Patients With Breast Cancer

An Early Phase 1 interventional study of Implanted Medical Device and Therapeutic Conventional Surgery in Positive Axillary Lymph Node, Stage 0 Breast Cancer AJCC v6 and v7 and Stage I Breast Cancer AJCC v7, sponsored by Jonsson Comprehensive Cancer Center. Completed at 1 site in United States. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2023-01-17.

Study summary

This pilot clinical trial will evaluate whether the SCOUT reflector can be used to tag abnormal lymph nodes in patients with breast cancer prior to chemotherapy for targeted removal at the time of surgery. The SCOUT localization system with the SAVI reflector is non-radioactive and completely internal so can be placed into an abnormal lymph node prior to chemotherapy treatment, which theoretically will allow easier identification and therefore more reliable targeting of the abnormal lymph node for surgical removal.

Read the detailed description

PRIMARY OBJECTIVES:

I. Percentage of patients with successful retrieval of the reflector confirmed by specimen radiography.

II. Percentage of patients with successful retrieval of the biopsied node, confirmed by presence of clip, biopsy changes or treatment-related changes on pathology.

SECONDARY OBJECTIVES:

I. Total number of lymph nodes removed. II. Percentage of patients in which clipped node was a sentinel node. III. Percentage of patients with nodal pathologic complete response (PCR). IV. Residual cancer burden (RCB) score for patients with residual nodal disease.

V. Percentage of patients requiring axillary dissection. VI. Days prior to surgery of reflector insertion.

OUTLINE:

Patients undergo image-guided placement of the SCOUT reflector prior to course 2 of standard of care neoadjuvant chemotherapy. Patients undergo standard of care surgery approximately 4-8 weeks after chemotherapy completion.
