Recurrent breast cancer accounts for most disease-associated mortality and can develop decades after primary tumor therapy. Recurrences arise from residual tumor cells (RTCs) that can evade therapy in a dormant state, however the mechanisms enforcing dormancy in RTCs are poorly understood. CRISPR-Cas9 screening identified the transcription factors SOX5/6 as functional regulators of tumor recurrence. Loss of SOX5 accelerated recurrence at both local and metastatic sites and promoted dormancy escape in both therapy-associated and microenvironment-induced contexts. Remarkably, SOX5 drove dormant RTCs to adopt a cartilage-dependent bone development program, termed endochondral ossification, that was confirmed by [18F]NaF-PET imaging and reversed in recurrent tumors escaping dormancy. Consistent with findings in mice, osteochondrogenic expression signatures in patients were enriched in residual disease following neoadjuvant therapy, and their enrichment in primary breast cancers predicted improved recurrence-free survival. These findings identify SOX5-dependent mesodermal transdifferentiation as an adaptive mechanism that prevents recurrence by reinforcing tumor cell dormancy.
