Preoperative receipt of neoadjuvant therapy, shorter daily sleep duration, high anxiety state, avoidance coping tendency, resignation coping tendency and poor social support are identified as associated factors. Nursing staff should provide targeted interventions to reduce patients\u2019 uncertainty and enhance their psychological adaptation, thereby facilitating postoperative recovery and improving quality
