[Sacituzumab govitecan in a triple-negative breast cancer patient journey: a cutting-edge story.]

Triple-negative breast cancer (TNBC) poses a challenge due to high metastatic potential and few care options. The successful management of relapsed disease is an unmet clinical need, to date. The antibody drug conjugate sacituzumab govitecan (SG) has been an actual breakthrough in the metastatic TNBC (mTNBC) algorithm. Herein, we report the case of a 45-year-old patient, who was referred to our centre for a hard-to-treat locoregional relapse from TNBC, thus receiving SG in third-line setting for 15 months. We also discuss clinical presentation, treatment patterns and outcomes along with a brief literature review. Our case study outlines the long-term efficacy of third-line SG in a TNBC patient with a refractory disease. Thanks to SG use within a multimodal patient journey, a sustained disease control along with a preserved quality of life was gained. Further real-world data is awaited to confirm these findings.
