Summary
Diagnosing primary central nervous system lymphoma (PCNSL) is often delayed, impacting patient outcomes. Early neuroimaging and biopsy are crucial for timely PCNSL diagnosis, especially for patients with subtle symptoms or initial negative imaging results.
Area of Science:
- Neurology
- Oncology
- Radiology
Background:
- Primary central nervous system lymphoma (PCNSL) presents with variable clinical and radiological features.
- Timely diagnosis and treatment of PCNSL are essential for improving patient survival and reducing long-term sequelae.
Purpose of the Study:
- To investigate diagnostic delays in primary central nervous system lymphoma (PCNSL).
- To identify factors contributing to delayed PCNSL diagnosis.
- To propose strategies for earlier PCNSL detection.
Main Methods:
- Retrospective review of medical records for 74 PCNSL patients in Norway (1989-1998).
- Analysis of time from initial symptom to final morphological diagnosis, including time to neuroimaging and diagnosis post-imaging.
- Comparison of diagnostic timelines between AIDS and non-AIDS patients.
Main Results:
- Significant diagnostic delays were observed in both AIDS and non-AIDS PCNSL patients.
- In non-AIDS patients, delayed diagnosis was associated with initial neuroimaging reports showing no tumor and non-confirmatory first biopsies.
- AIDS patients' PCNSL diagnoses were exclusively established by autopsy, indicating substantial delays.
Conclusions:
- Considerable delays in PCNSL diagnosis necessitate improved diagnostic strategies.
- Early neuroimaging is recommended for patients with personality changes or visual disturbances.
- Repeated neuroimaging and biopsy are advised for persistent neurological symptoms or focal brain lesions, particularly when initial imaging is inconclusive.
