Comparative Evaluation of [99mTc]Tilmanocept for Sentinel Lymph Node Mapping in Breast Cancer Patients: Results of Two Phase 3 Trials

description Background Sentinel lymph node (SLN) surgery is used worldwide for staging breast cancer patients and helps limit axillary lymph node dissection. [ 99m Tc]Tilmanocept is a novel receptor-targeted radiopharmaceutical evaluated in 2 open-label, nonrandomized, within-patient, phase 3 trials designed to assess the lymphatic mapping performance. Methods A total of 13 centers contributed 148 patients with breast cancer. Each patient received [ 99m Tc]tilmanocept and vital blue dye (VBD). Lymph nodes identified intraoperatively as radioactive and/or blue stained were excised and histologically examined. The primary endpoint, concordance (lower boundary set point at 90 %), was the proportion of nodes detected by VBD and [ 99m Tc]tilmanocept. Results A total of 13 centers contributed 148 patients who were injected with both agents. Intraoperatively, 207 of 209 nodes detected by VBD were also detected by [ 99m Tc]tilmanocept for a concordance rate of 99.04 % ( p

[ 99m Tc]tilmanocept detected a total of 320 nodes, of which 207 (64.7 %) were detected by VBD. [ 99m Tc]Tilmanocept detected at least 1 SLN in more patients (146) than did VBD (131, p  &lt; 0.0001). In 129 of 131 patients with ≥1 blue node, all blue nodes were radioactive. Of 33 pathology-positive nodes (18.2 % patient pathology rate), [ 99m Tc]tilmanocept detected 31 of 33, whereas VBD detected only 25 of 33 ( p  = 0.0312). No pathology-positive SLNs were detected exclusively by VBD. No serious adverse events were attributed to [ 99m Tc]tilmanocept. Conclusion [ 99m Tc]Tilmanocept demonstrated success in detecting a SLN while meeting the primary endpoint.
