A study to evaluate effectiveness of sublobar dissection in patients with non-small cell lung cancer

This is a multi-centre real-world non-interventional observational study. The study data on patient demographic/tumor biological characteristics and clinical treatments were retrospectively collected to evaluate effectiveness of sublobar dissection in the Chinese patients with non-small cell lung cancer who received sublobar dissection.

Inclusion Criteria:

• Patients >= 18 years old;
• Patients who received sublobar dissection from 2014 to 2017 (segment dissection/wedge dissection/segment and wedge dissections);
• Patients who received selective or systematic lymphadenectomy;
• Pathologically diagnosed patients with non-small cell lung cancer;
• Pathological staging: I, II

Exclusion Criteria:

• Patients who received cancer treatments before surgeries (adjuvant therapies including chemotherapies, radiotherapies, target therapies);
• Patients who received late-phase or intolerant palliative lobectomy or compromise sublobar dissection;
