Evaluating ablation therapy for lung cancer with ground-glass nodules

A Prospective, Two-center, Single Arm Phase II Clinical Study to Evaluate Safety and Effectiveness of Ablation Therapy in the Treatment of Lung Cancer Presenting as Ground-glass Nodules

PHASE2 · Shanghai Zhongshan Hospital · NCT04905056

This study is testing if a special treatment called ablation therapy can help people with lung cancer that shows up as ground-glass nodules when they can't have regular surgery.

What this trial studies

This clinical trial is a prospective, two-center, single-arm Phase II study aimed at assessing the safety and effectiveness of ablation therapy for patients with lung cancer presenting as ground-glass nodules. Participants will be individuals aged 18 to 85 years who have been diagnosed with ground-glass opacities (GGOs) that have not improved after three months. The study will focus on patients who are unable to undergo traditional surgical procedures due to various reasons, including the presence of multiple nodules or previous surgeries. The primary goal is to determine how well ablation therapy can manage these specific lung cancer cases.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 to 85 with diagnosed GGOs that have shown progression and are not suitable for surgical intervention.

Not a fit: Patients with severe comorbid conditions, cognitive impairments, or those who have recently participated in other clinical trials may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could provide a less invasive option for managing lung cancer in patients with ground-glass nodules.

How similar studies have performed: While there is limited information on similar studies, the approach of using ablation therapy for lung cancer is gaining interest, indicating potential for success.
