The staging system for lung tumours is now recommended for the classification of both non-small-cell and small-cell lung cancer as well as for carcinoid tumours of the lung. The T classifications have been redefined: T1 has been subclassified as T1a (≤ 2 cm in size) and T1b (> 2-3 cm in size). T2 has been subclassified as T2a (> 3-5 cm in size) and T2b (> 5-7 cm in size). T2 (> 7 cm in size) has been reclassified as T3. Multiple tumour nodules in the same lobe have been reclassified from T4 to T3. Multiple tumour nodules in the same lung but a different lobe have been reclassified from M1 to T4. No changes have been made in the N classification. The M classification has been redefined: M1 has been subdivided into M1a and M1b. Malignant pleural and pericardial effusions have been reclassified from T4 to M1a. Separate tumour nodules in the contralateral lung have been reclassified from T4 to M1a. M1b designates distant metastasis.
目前推荐使用肺肿瘤分期系统对非小细胞肺癌、小细胞肺癌以及肺类癌肿瘤进行分类。T分类已重新定义：T1已细分为T1a（大小≤2 cm）和T1b（大小>2 - 3 cm）。T2已细分为T2a（大小>3 - 5 cm）和T2b（大小>5 - 7 cm）。大小>7 cm的T2已重新分类为T3。同一肺叶内的多个肿瘤结节已从T4重新分类为T3。同一肺内但不同肺叶的多个肿瘤结节已从M1重新分类为T4。N分类未作更改。M分类已重新定义：M1已细分为M1a和M1b。恶性胸腔和心包积液已从T4重新分类为M1a。对侧肺内的孤立肿瘤结节已从T4重新分类为M1a。M1b表示远处转移。
