About this study
Official title: Active Surveillance for Patients with Multifocal Ground-glass Nodules: a Prospective, Multi-center, Single-arm Trial (ECTOP-1021)
This study is a single-arm, multi-center, phase III trial conducted under the Eastern Cooperative Thoracic Oncoloy Project (ECTOP) with the identification number ECTOP-1021. The primary objective of the study is to assess the overall survival of patients with multifocal ground-glass opacities by employing a active surveillance approach rather than opting for surgical resection.
Read the detailed description
The trial aims to confirm the hypotheses that delaying surgery until GGO nodules exhibit progression or meet certain criteria offers a prognosis equivalent to those undergoing immediate surgical resection, potentially allowing many of these patients to avoid surgery altogether.
- Conditions
- Lung Ground-glass Opacities, Active Surveillance
- Being tested
- Watchful waiting
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Watchful waitingProcedure or surgery
Conduct thoracic computed tomography scans every 12 months. The decision regarding surgery is based on the surgeon's evaluation of radiologic follow-up. The reference resection criteria encompass: a) Any lesion that progresses to a tumor diameter larger than 2cm or has CTR greater than 0.25. b) Clinical Tumor, node, metastasis (TNM) stage upstaging.

What is being measured
The primary outcome is the main question the study is designed to answer.
5-year overall survival
The event is defined as the death due to any causes.
Measured: 5 years
