About

The objective is to screen and monitor the efficacy of cfDNA methylation in patients with stage I lung cancer after ablation, to compare the similarities and differences of cfDNA methylation between surgical treatment and ablation in patients with stage I lung cancer, and to look for new indicators to assess the efficacy of ablation therapy and to monitor lung cancer recurrence.

Full description

The objective is to screen and monitor the efficacy of cfDNA methylation in patients with stage I lung cancer after ablation, to compare the similarities and differences of cfDNA methylation between surgical treatment and ablation in patients with stage I lung cancer, and to look for new indicators to assess the efficacy of ablation therapy and to monitor lung cancer recurrence.

The main research content is to screen the cfDNA methylation index that can monitor the efficacy of stage I lung cancer ablation and compare the similarities and differences of cfDNA methylation in patients with stage I lung cancer after surgery and ablation.

Enrollment: 90 estimated patients

Sex: All

Ages: 18 to 85 years old

Volunteers: No Healthy Volunteers

Inclusion criteria

1. Age: 18-85 years old;
2. The peripheral pulmonary nodules found in patients with chest CT, preoperative examination showed that the clinical stage of patients was T1N0M0, IA;
3. patients are not suitable for surgical treatment through multidisciplinary assessment, agree to accept ablation
4. Patients have good compliance with the tests and follow-ups, understand the situation of the study and sign informed consent.

Exclusion criteria

1. The patient is generally in poor condition and cannot tolerate the examination;
2. patients with a cardiac pacemaker or stent in the heart; peripheral tumors of the lungs are adjacent to large blood vessels or important structures;
3. patients with poor compliance;

90 participants in 2 patient groups

ablation group

Experimental group

Description:

Patients with stage IA inoperable peripheral lung tumor will be performed ablation. cfDNA methylation would be monitored at different times(before surgery , after surgery 1month, 3month, and every 3month in the first year and every 6 months in the second ). Meanwhile, post-treatment response will be evaluated and follow up will be carried out according to the standard procedure.

Treatment:

Other: ablation

surgery group

Experimental group

Description:

Patients with stage IA operable peripheral lung tumor will be performed surgery. cfDNA methylation would be monitored at different time(before surgery , after surgery 1month, 3month). Post-treatment response will be evaluated and follow up will be carried out according to the standard procedure.

Treatment:

Other: surgery
