Because it is difficult to determine the metastasis-status, which is a factor in determining whether to remove lymph-nodes, decisions are often made based on the doctor's experience. If lymph-nodes that do not need to be removed are removed, metabolic-waste is not separated, causing serious edema, which significantly reduces the patient's quality of life. AiAlpa-Platform can predict metastasis-rates in real-time during surgery (Prediction-accuracy/F1-Score: 90%), preventing the removal of normal lymph-nodes.
