Robotic surgical systems provide notable advantages including enhanced dexterity, a magnified three-dimensional high-definition view, and high-resolution imaging, thereby improving operative stability and precision. These features make robotic systems particularly suitable for procedures performed within confined operative spaces. As the breast is a solid organ without a natural cavity, robotic systems demonstrate strong adaptability for breast surgery. Robot-assisted breast-conserving surgery (RABCS) is one of the currently utilized robotic techniques in clinical breast cancer surgery. However, as robotic breast surgery remains in its early stage of development, evidence regarding the clinical outcomes of RABCS remains limited in the literature. Therefore, this study compares the surgical outcomes of endoscopic breast-conserving surgery and robot-assisted breast-conserving surgery in breast cancer patients, aiming to assess and elucidate the clinical value of RABCS.
