ClinConnect Summary

This clinical trial is looking at how to better choose surgical options for patients with stage IA lung adenocarcinoma, a type of lung cancer. The researchers are studying past medical records and CT scans to identify factors that might indicate whether the cancer has spread through the air spaces in the lungs, which can make treatment more complicated. Understanding these factors can help doctors decide on the best surgical approach for each patient.

To participate in this study, individuals must be at least 18 years old and have a specific type of lung nodule (less than 3 cm in size) that has been diagnosed as invasive lung adenocarcinoma through a biopsy. Participants must have had their CT scans done at Yunnan Cancer Hospital within two weeks before their surgery, and it’s important that their scans show no signs of cancer spreading to other parts of the body. If you fit these criteria, this trial could help improve future treatment options for lung cancer patients.
