Brief summary

Video-assisted thoracic surgery (VATS) has been recommended by clinical guidelines as one of the preferred surgeries for early-stage non-small cell lung cancer (NSCLC) for many years. However, VATS has inherent drawbacks, so at the beginning of this century, robotic-assisted thoracoscopic surgery (RATS) was first applied for lung resection. In recent years, RATS has developed rapidly, but there are still many unsolved scientific problems in the field of RATS. Thus, a multicenter prospective randomized controlled trial was conducted with stage I-II NSCLC patients as the study subject and 5-year DFS as the primary endpoint to compare the short-term and long-term outcomes of RATS and VATS in the treatment of early-stage NSCLC.

Secondary

MeasureTime frameDescription
3-year disease-free survival (DFS)3 years after surgeryDifference of 3-year disease free survival rate between the two groups
3-year overall survival (OS)3 years after surgeryDifference of 3-year overall survival rate between the two groups
Blood lossDuring the surgeryBlood loss during the surgery
Conversion rateDuring the surgeryThe number of patients converted to thoracotomy divided by the total number of included patients in a group
Perioperative complicationThe day of surgery, 2/4/8/12/26/52 weeks after surgeryIntraoperative and postoperative complications
Operative death rate30/90 days after surgeryThe number of patients died within 30/90 days after surgery divided by the total number of included patients in a group
Hospital stays after surgeryBetween the date of surgery and the date of discharge, assessed up to 30 daysThe length of stay in hospital after surgery
5-year overall survival (OS)5 years after surgeryDifference of 5-year overall survival rate between the two groups
R0 ratePostoperative in-hospital stay up to 30 daysThe number of patients received R0 surgery divided by the total number of included patients in a group
Operative timeDuring the surgeryThe total time from skin to skin and the time of each step were recorded
The number of resected lymph nodesPostoperative in-hospital stay up to 30 daysThe number of resected lymph nodes were calculated according to the official pathological report after surgery
Chest tube durationPostoperative in-hospital stay up to 30 daysThe number of days between the date of surgery and the date of chest tube removal
Acesodyne (Grade III) dosePostoperative in-hospital stay up to 30 daysThe total amount of morphine used by the patient during the postoperative hospital stay, including morphine, pethidine, and fentanyl etc.
Total cost of hospitalizationFrom the date of admission to the date of discharge, assessed up to 30 daysThe total cost of the patient from admission to discharge
Pain score after surgeryScores were given daily after surgery and at weeks 2/4/8/12/26/52 after dischargeThe degree of pain after surgery was measured using Numerical Rating Scale (NRS). The patient is asked to make three pain ratings, corresponding to current, best and worst pain experienced over the past 24 hours on a scale of 0 (no pain) to 10 (worst pain imaginable). The average of the 3 ratings was used to represent the patient's level of pain over the previous 24 hours.
