根据美国外科学会ACOSOG Z4032/Z0030研究的定义整理如下：
局部复发（Local failure，local recurrence ）:
1. 原发灶邻近的肺组织，支气管残端，邻近支气管残端的肺门。[Adjacent lung parenchyma, bronchial stump, or in the hilum adjacent to the bronchial stump].
2. 以下用于局限性切除的病例，如肺楔形切除术。
2.1 复发位于原发肺叶的切除线 (局部进展，local progression)；[Recurrence within the primary tumor lobe at the staple line (local progression)]；
2.2 复发位于原发肺叶但远离切除线 (累及肺叶失败，involved lobe failure)[Recurrence within the primary tumor lobe away from the staple line (involved lobe failure)]
2.3 复发位于肺门淋巴结（Recurrence within hilar lymph nodes.）
区域复发（Regional failure，Regional recurrence）:
1. 复发部位在与支气管残端不连续的肺门组织，纵隔，胸壁或者同侧胸膜；[hilum separate from bronchial stump, in the mediastinum, chest wall,or ipsilateral pleura].
2. 复发位于手术同侧其他肺叶，或者在同侧纵隔或者隆突下淋巴结。[defined as recurrence within another lobe on the same side as the resection or within ipsilateral mediastinal or subcarinal lymph nodes].
远处转移（Distant failure，Distant recurrence）:
1. 对侧胸腔，对侧纵隔或者肺门淋巴结，或者远处器官转移。（Distant recurrence was defined as recurrence within contralateral, mediastinal, or hilar lymph nodes or distant metastatic disease.）
