Case Discussion Advanced NSCLC
Dexamethasone
Resection of cerebral metastasis as initial therapy- March 20, 2001- Severe symptoms required rapid relief- Squamous cell carcinoma plus large cell carcinoma
with neuroendocrine features, compatible with NSCLC
Rapid postoperative recovery- Nausea & headache disappeared
Postoperative whole-brain radiotherapy- 30 Gy (May – June 2001)
![Page 13: Aucun titre de diapositive](https://reader033.vdocuments.net/reader033/viewer/2022052619/5560e3b4d8b42afb7b8b4b41/html5/thumbnails/13.jpg)
Brain metastasis
Frequent in lung cancer - Synchronous - Metachronous
Therapy- Surgery - Stereotactic radiosurgery - Whole-brain radiotherapy - Disease status outside of the brain must be considered
![Page 14: Aucun titre de diapositive](https://reader033.vdocuments.net/reader033/viewer/2022052619/5560e3b4d8b42afb7b8b4b41/html5/thumbnails/14.jpg)
Therapy of brain metastasisPeacock KH & Lesser GJ. Curr Treat Options Oncol 2006, 7, 479
Surgery- Single metastasis >3.5 cm- Immediate tumor relief necessary- Pathological diagnosis required- Small tumors with minimal edema & surgically
accessible
Stereotactic radiosurgery- Metastasis <3.5 cm in surgically inaccessible areas- Patients not suited fur surgery- Small tumors with minimal edema (even when
surgically accessible)

Stereotactic radiosurgery plus/minus whole-brain radiotherapy
Aoyama H et al. JAMA 2006, 295, 2483
• 142 patients, 1 - 4 metastases (< 3 cm)
SRS SRS+WBRT p value
Os median 8 mo 7.5 0.4
1-year 28% 38%
Brain relapse 76% 47% <0.001
Salvage therapy brain ↑
• WBRT decreases brain relapse rate but does not improve survival

Brain metastasis
Metachronous- Better prognosis than synchronous lesions (33 vs. 9 months
from time of diagnosis of NSCLC, p=0.001) but no difference from time of metastasis (12 vs. 8 months, p=0.5) Flannery TW et al. Lung Cancer 2003, 42, 327

Patient Case Discussion Advanced NSCLC
Summary
• Brain metastases are frequent in lung cancer (synchronous, metachronous)
• Surgery, stereotactic radiosurgery, whole-brain radiotherapy
• Resection of single brain metastasis and primary tumor can result in long-term survival in patients- with good performance status and- absence of mediastinal lymph node involvement
• Resection or radiosurgery (+/- whole-brain radiotherapy) of metachronous single metastasis can also result in long-term survival
• Not all of the treatment decisions were based on randomized trials

Surgery in NSCLC IV
• Resection of single cerebral metastasis
• Resection of lung metastasis- Single lung metastasis rare at initial diagnosis
- Staging
- Secondary primary
• Resection of single bone lesion- Palliative
