Magnetic seed versus guidewire-based breast cancer localization with magnetic lymph node detection: cost-minimization analysis

1

Magnetic seeds offer comparable performance to guidewires for breast lesion localization, with advantages in operating time and staff satisfaction.
2

A cost-minimization analysis revealed that magnetic seeds resulted in reduced costs compared to guidewires, despite their higher device cost.
3

The adjusted analysis showed a cost difference of €391 favoring magnetic seeds, corresponding to an 11.1% reduction in costs.
4

The study included 426 patients with non-palpable breast cancer, randomized to receive either magnetic seed or guidewire localization.
5

Healthcare practitioners reported higher satisfaction with magnetic seeds, primarily due to improved scheduling and reduced operating delays.
