Uniportal Versus Triportal Thoracoscopic Lobectomy and Sublobectomy for Early Stage Lung Cancer
- Conditions
- Lung Neoplasms
- Interventions
- Procedure: Triportal pulmonary resection surgeryProcedure: Uniportal pulmonary resection surgery
- Registration Number
- NCT02933294
- Brief Summary
Lung cancer is one of the most common cancers in the world. At present, surgical resection is still the standard treatment for early stage lung cancer. Triportal thoracoscopic lung resection is a routine surgically procedure for early stage lung cancer while uniportal thoracoscopic lung resection is developing rapidly in recent years. Although uniportal VATS pulmonary resection has been proven to be effective in preventing postoperative morbidities, there is still no ample evidences to demonstrate that uniportal VATS pulmonary resection is equal or superior to traditional triportal thoracoscopic pulmonary resection. The purpose of this multicenter randomized controlled trial study is to compare the uniportal VATS with traditional triportal VATS pulmonary resection in postoperative complications, long-term survival, lymph node dissection and local recurrence.
- Detailed Description
Lung cancer is one of the most common cancers in the world，especially in China, where the mortality ranked first in malignant tumors whether for males or females. At present, VATS (Video-assisted thoracoscopic surgery) lobectomy is still the "gold standard" for the treatment of lung cancer. Triportal thoracoscopic lung resection is a routine surgically procedure for early stage lung cancer while uniportal thoracoscopic lung resection is developing rapidly in recent years. Retrospective study in recent years showed that the postoperative complication rate is similar between uniportal thoracoscopic surgery and triportal thoracoscopic surgery. Meanwhile, the incision is more pleasing, the inflammatory response may be milder and the hospitalization time may be shorter in the uniportal thoracoscopic surgery. But until now there is no result of the randomized controlled study on the effectiveness and the prognosis between uniportal thoracoscopic surgery and triportal thoracoscopic surgery to support this conclusion. The objective of this multicenter randomized controlled trial study is to compare the postoperative complications, long-term survival, local recurrence, other perioperative variables such as conversion rate, blood loss, lymph nodes retrieved and postoperative hospital stay between the triportal VATS pulmonary resection and uniportal VATS pulmonary resection on early stage lung cancer.

- Arm && Interventions
Group Intervention Description Triportal pulmonary resection surgery Triportal pulmonary resection surgery Treated by traditional video assisted thoracoscopic three-port pulmonary resection in the centers with enough experience in VATS and the volume ≧50 cases each year. Uniportal pulmonary resection surgery Uniportal pulmonary resection surgery Treated by minimally invasive video assisted thoracoscopic single-port pulmonary resection in the centers with enough experience in VATS and the volume ≧50 cases each year.
- Primary Outcome Measures
Name Time Method Postoperative respiratory complications 30 days after surgery These respiratory complications involve respiratory distress or failure after the operation with continuation of mechanical ventilation, pulmonary atelectasis requiring sputum suction by bronchoscopy, pneumonia requiring specific antibiotics confirmed by thoracic X-ray or CT scan of the thorax and a positive sputum culture, and acute respiratory distress syndrome.
- Secondary Outcome Measures
Name Time Method Local recurrence 3 years three-year local recurrence rate after surgery
Conversion rate Intraoperation conversion to thoracotomy during surgery
Blood loss Intraoperation blood loss during the surgery
Long term survival 5 year five-year survival rates after surgery
Lymph node dissection Intraoperation During the surgery, lymph node dissection were performed. The number of removed lymph-nodes were recorded according to the postoperative pathological diagnosis, and the stations of the lymph node were recorded according to the International Association for the Study of Lung Cancer (IASLC) Lymph Node Map.
