Cerebral metastasis without known primary tumour: a retrospective study
Clinical Neurology and Neurosurgery
|January 1, 1978
Summary
Surgery for intracerebral metastasis from unknown primary tumors offers limited survival. In most cases, the primary tumor remains unidentified, highlighting challenges in diagnosis and treatment for these rare brain metastases.
Area of Science:
- Neurosurgery
- Oncology
- Pathology
Background:
- Intracerebral metastases represent secondary brain tumors.
- Unknown primary tumors (UPTs) pose diagnostic challenges.
- Surgical management of brain metastases aims to improve outcomes.
Purpose of the Study:
- To evaluate the outcomes of surgical intervention for intracerebral metastases of unknown primary origin.
- To determine the rate of primary tumor identification post-surgery.
Main Methods:
- Retrospective analysis of 19 patients undergoing surgery for intracerebral metastasis.
- Review of clinical data, surgical records, and follow-up information.
Main Results:
- Most patients (19) had limited survival post-operation.
- Two patients experienced remarkable long-term survival.
- The primary tumor became clinically manifest in only 8 patients during follow-up.
Conclusions:
- Surgical resection of intracerebral metastases from UPTs offers palliative benefit but generally poor prognosis.
- The primary tumor often remains occult, complicating treatment strategies.
- Further research is needed to improve the identification and management of unknown primary brain metastases.
