Spinal cord compression in breast cancer.

Area of Science:

• Oncology
• Neurology
• Radiology

Background:

• Spinal cord compression is a serious complication in patients with metastatic breast cancer.
• Early and accurate diagnosis is crucial for timely management and potentially improving outcomes.

Purpose of the Study:

• To evaluate the diagnostic accuracy of myelography in detecting spinal cord lesions in breast cancer patients.
• To correlate myelographic findings with clinical symptoms, imaging results, and patient prognosis.

Main Methods:

• Myelography was performed on 78 breast cancer patients presenting with symptoms suggestive of spinal cord compression.
• Clinical signs, symptoms, cerebrospinal fluid (CSF) analysis, bone scans, and skeletal x-rays were correlated with myelographic results.
• Treatment response and survival rates were analyzed in relation to myelographic findings and disease burden.

Main Results:

• Myelography identified extradural defects in 54% of patients, with 50% of these showing a complete block.
• Positive myelograms (M+) correlated strongly with positive bone scans (100%) and skeletal x-rays (97%).
• Clinical symptoms like back pain and bladder/bowel dysfunction were more frequent in M+ patients, though not highly specific for cord lesions.

Conclusions:

• Myelography is the most precise diagnostic tool for spinal cord lesions in breast cancer patients.
• Despite accurate diagnosis, the overall prognosis for metastatic breast cancer with spinal cord compression is poor.
• Treatment response is influenced by metastatic burden and time from diagnosis, but survival is not significantly impacted by myelographic findings.
