[Current Status of Molecular Residual Disease Testing in Genitourinary Cancers].

Recent advancements of surgery including robotic surgery have improved the clinical outcomes of resectable solid tumors. Although preoperative chemotherapy is often performed for high-risk cancers, the risk of postoperative recurrence remains a critical issue. So far, recurrence has been monitored through periodic imaging tests; however, molecular residual disease (MRD)has caught much attention as the means to detect minimal cancerous lesions at an earlier stage. With the rapid advancements in circulating tumor DNA(ctDNA)analysis using next-generation sequencing, MRD testing is emerging as a promising tool for predicting recurrence in multiple types of cancer. Thus, in this article, we discuss the current status of MRD testing in urogenital cancers and its potential impact on future treatment strategies.
