Purpose: Although multiple radiopharmaceuticals are currently available for sentinel node (SN) biopsy,
99m Tc-tilmanocept is of particular interest due to its low molecular weight and specific binding capability for the mannose receptors of lymphatic reticuloendothelial cells. In the current systematic review and meta-analysis, we aimed to provide an update from a European expert panel on the performance of99m Tc-tilmanocept for SN biopsy. Methods: A systematic literature search of the PubMed/Medline and Embase databases was performed to identify studies on the use of99m Tc-tilmanocept for SN identification in oncological patients. The articles' methodological quality was assessed before inclusion. The pooled estimates of the pre-/intraoperative detection rates (DR; proportion of patients with ≥ 1 SN identified) and/or pN + sensitivity (SN + /pN + patients ratio), with 95% confidence intervals (CIs), were calculated for breast cancer, melanoma, and head and neck cancer. Results: Twenty-four articles were included in the systematic review, and twenty-one provided data for the meta-analysis. According to data availability, the99m Tc-tilmanocept-estimated pooled preoperative and intraoperative DRs were 0.94 (95%CI, 0.88–1.01) and 0.99 (0.98–1.00) for breast cancer, 0.98 (0.96–0.99) and 1.00 (0.99–1.00) for melanoma, and 0.97 (0.93–1.02) and 0.99 (0.96–1.01) for head and neck carcinoma. Finally, the pooled sensitivity for nodal metastasis in melanoma was 0.97 (95% CI, 0.92–1.03). Conclusion:99m Tc-tilmanocept is a promising radiotracer for SN mapping in patients with breast cancer, melanoma, or head and neck cancer. We strongly believe that multicenter trials are still needed to assess if99m Tc-tilmanocept is superior to other radiotracers used in clinical routine. [ABSTRACT FROM AUTHOR]- Published
