Review Meta Analysis Comparative StudyThe efficacy of Tilmanocept in sentinel lymph mode mapping and identification in breast cancer patients: a comparative review and meta-analysis of the ⁹⁹mTc-labeled nanocolloid human serum albumin standard of care.
Sentinel lymph node (SLN) mapping is common, however question remains as to what the ideal imaging agent is and how such an agent might provide reliable and stable localization of SLNs. (99m)Tc-labeled nanocolloid human serum albumin (Nanocoll) is the most commonly used radio-labeled colloid in Europe and remains the standard of care (SOC). It is used in conjunction with vital blue dyes (VBDs) which relies on simple lymphatic drainage for localization. Although the exact mechanism of Nanocoll SLN localization is unknown, there is general agreement that Nanocoll exhibits the optimal size distribution and radiolabeling properties of the commercially available radiolabel colloids. [(99m)Tc]Tilmanocept is a novel radiopharmaceutical designed to address these deficiencies. ⋯ The lower bound of the confidence interval was used for comparison to Tilmanocept. Tilmanocept data included 148 patients, and pooled analysis revealed a 99.99 % (CI 0.9977-1.0000) localization rate and degree of localization of 2.16 (CI 1.964-2.3600). Tilmanocept was superior to the Nanocoll SOC for both endpoints (P < 0.0001).
