Conditions

Procedure: sequential surgery
Procedure: ENB guided MWA combined with VATS
Registration Number
NCT05662553
Lead Sponsor
Ruijin Hospital
Brief Summary

The goal of this clinical trial is to evaluate the safety and efficacy of ENB guided MWA combined with VATS versus sequential surgery for synchronous bilateral multiple primary lung nodules. Participants will be divided into two group.One group will accepte treatment of ENB guided MWA combined with VATS,another will accepted sequential surgery.

Detailed Description

Lung cancer is one of the most common cancers and the leading cause of cancer-related death worldwide. With the improvement of people's health awareness and the wide application of LDCT and HRCT, the incidence of multiple primary lung cancer is increasing, especially the synchronous bilateral multiple primary pulmonary nodules are the difficulties in the treatment of pulmonary nodules. Bilateral sequential surgery is associated with higher intraoperative risks, higher rates of postoperative complications, and lower postoperative quality of life. At present, a small number of recent retrospective studies have shown that microwave ablation(MWA) guided by electromagnetic navigation bronchoscopy(ENB) combined with video-assisted thoracic surgery(VATS) treatment can effectively treat bilateral multiple primary pulmonary nodules, which not only has a low complication rate, but also can avoid secondary surgery.

Based on previous studies, the research plans to conduct a prospective, multi-center, randomized controlled study to evaluate the safety and efficacy of ENB guided MWA combined with VATS versus sequential surgery for synchronous bilateral multiple primary lung nodules, as well as its potential value as a new treatment option for these participants.

GroupInterventionDescription
Surgerysequential surgeryThe control group will undergo VATS treatment on the primary lesion on the day of operation, and will be re-admitted to the hospital after discharge and recovery (3-4 months) for contralateral secondary lesion surgery.
AblationENB guided MWA combined with VATSAfter randomization, the enrolled patients in this arm should be performed path simulation under ENB with preoperative CT. On the operation day, single-cavity intubation will be carried out first, and the secondary lesion will be reached through the planned path. After that,the biopsy tissue of the lesion will be sent to ROSE for detection. If malignant,the ablation will be performed,and the location, energy and ablation time will be adjusted according to intraoperative CT. After ablation, radical surgery will be performed on the primary lesion.
