Table II.
Recurrence patterns and time to recurrence in patients with high-grade glioma.
| Recurrence pattern | Patients, n (%) | Time to recurrence (months), median (range) | Recurrence rate at 1 year (%) | Recurrence rate at 2 years (%) |
|---|---|---|---|---|
| Central recurrence | 34 (63.0) | 11 (2–30) | 56 | 94 |
| In-field recurrence | 8 (14.8) | 9 (3–11) | 100 | 100 |
| Marginal recurrence | 2 (3.7) | 30 (2–58) | 50 | 50 |
| Distant recurrence | 2 (3.7) | 19 (2–35) | 50 | 50 |
| CSF-d | 11 (20.4) | 10 (5–58) | 55 | 82 |
The time to recurrence was calculated from the date of pathological diagnosis. Of the 11 patients who developed CSF-d, 2 developed central recurrence and 1 simultaneously developed marginal recurrence. CSF-d, cerebrospinal fluid dissemination.
