2005年Fleischner学会关于 < 8 mm的肺结节的随访方案和处理原则
Recommendations for follow-up and management of nodules smaller than 8 mm detected incidentally at nonscreening CT from the Fleischner scocity in 2005
| Nodule size (mm) (Average of length and width) | Low-risk patient (Minimal or absent history of smoking and of other known risk factors) | High-risk patient (History of smoking or of other known risk factors) |
| Nonsolid (ground-glass) or partly solid nodules may require longer follow-up to exclude indolent adenocarcinoma. | ||
| ≤4 | No follow-up needed | Follow-up CT at 12 mo; if unchanged, no further follow-up |
| > 4-6 | Follow-up CT at 12 mo; if unchanged, no further follow-up | Initial follow-up CT at 6-12 mo then at 18-24 mo if no change |
| > 6-8 | Initial follow-up CT at 6-12 mo then at 18-24 mo if no change | Initial follow-up CT at 3-6 mo then at 9-12 and 24 mo if no change |
| > 8 | Follow-up CT at around 3, 9 and 24 mo, dynamic contrast-enhanced CT, PET and/or biopsy | Same as for low-risk patient |
肺癌的风险评估
The relative risk for lung cancer
| Low-risk | Moderate-risk | High-risk | |
| Nodule size | < 8 mm | 8 mm-20 mm | > 20 mm |
| Age (year) | < 45 | 45-60 | > 60 |
| Previous history of cancer | No | Yes | Yes |
| Smoking status | Never | Smoking now, < 1 bag/day | Smoking now, ≥1 bag/day |
| Quit smoking | Quit smoking ≥7 years | Quit smoking < 7 years | Never quit smoking |
| Chronic obstructive pulmonary disease (COPD) | No | Yes | Yes |
| Asbestos exposure | No | No | Yes |
| Nodule feature | Smooth | Lobulation | Spiculation |
Fleischner学会关于CT检查发现的肺内伴实性结节的随访建议
Recommendations for the management of subsolid pulmonry nodules detected at CT: A statement from the Fleischner scocity
| Nodule type | Management recommendations | Additional remarks |
| GGN, ground glass nodule; These guidelines assume meticulous evaluation, optimally with contiguous thin sections (1 mm) reconstructed with narrow and/or mediastinal windows to evaluate the solid component and wide and/or lung windows to evaluate the nonsolid component of nodules, if indicated. The use of a consistent low-dose technique is recommended. With serial scans, always compare with the original baseline study to detect subtle indolent growth. | ||
| Solitary pure GGNs | ||
| ≤5 mm | No CT follow-up required | Obtain contiguous 1 mm thick sections to confirm that nodule is truly a pure GGN |
| > 5 mm | Initial follow-up CT at 3 months to confirm persistence then annual surveillance CT for a minimum of 3 years | FDG PET is of limited value, potentially misleading, and therefore not recommended |
| Solitary part-solid nodules | Initial follow-up CT at 3 months to confirm persistence. If persistent and solid component < 5 mm,then yearly surveillance CT for a minimum of 3 years. If persistent and solid component ≥5 mm,then biopsy or surgical resection | Consider PET/CT for part-solid nodules > 10 mm |
| Multiple subsolid nodules | ||
| Pure GGNs ≤5 mm | Obtain follow-up CT at 2 and 4 years | Consider alternate causes for multiple GGNs ≤5 mm |
| Pure GGNs > 5 mm without a dominant lesion (s) | Initial follow-up CT at 3 months to confirm persistence and then annual surveillance CT for a minimum of 3 years | FDG PET is of limited value, potentially misleading, and therefore not recommended |
| Dominant nodule (s) with part-solid or solid component | Initial follow-up CT at 3 months to confirm persistence. If persistent biopsy or surgical resection is recommended, especially for lesions with > 5 mm solid component | Consider lung-sparing surgery for patients with dominant leision (s) suspicious for lung cancer |
