Blood ctDNA detection of microscopic residual disease (MRD) to monitor recurrence after MWA for older early-stage lung cancer

CT-guided microwave ablation for the treatment of early-stage lung cancer in the elderly to improve the safety and efficacy evaluation of key technology research-blood ctDNA detection of tiny residual lesions (MRD) to monitor the recurrence of early-stage lung cancer in the elderly after MWA surgery.
