Abstract

Purpose

Spinal cord gliomas are rare, and there is no consensus on the optimal radiotherapy (RT) regimen. Herein, we investigated therapeutic outcomes in spinal cord gliomas to obtain clues for the optimal RT regimen.

Methods

We assessed 45 patients who received RT for primary spinal cord non-ependymoma gliomas between 2005 and 2017: 37 (82%) received postoperative RT, 6 (13%) underwent definitive RT without surgery, and 2 (5%) received salvage RT for recurrent tumors. Craniospinal irradiation (CSI; median, 40 Gy) was administered in 4 patients with seeding at diagnosis; all other patients received local RT only (median, 50.4 Gy).

Results

In all 23 failures occurred (20 in patients without initial seeding +3 in patients with initial seeding and CSI; median follow-up, 33 months). The 2‑year overall survival and progression-free survival rates were 74 and 54%, respectively. Overall, 13 (32%) new seeding events outside the local RT field developed either first or subsequently. Tumor grade was significantly associated with survival endpoints (p = 0.009, 0.028) and overall seeding rates (p = 0.042). In grade II tumors, seeding developed in 23%, with a dismal prognosis (median, 10 months after RT). In grade III tumors, seeding developed in 45% with diverse prognosis. In grade IV tumors, seeding developed in 45%. The survival of patients with newly developed seeding was significantly worse than the others (2-year 50%, p < 0.001).

Conclusion

To encompass a considerable rate of progressive disease seeding, aggressive treatment such as pre-emptive application of CSI needs to be considered for high-grade spinal cord gliomas with adverse features. Prophylactic CSI could be an option for survival prolongation and requires prospective validation.

Zusammenfassung

Zweck

Rückenmarksgliome sind selten, bezüglich der bestmöglichen Radiotherapie (RT) besteht kein Konsens. Untersucht wurden Behandlungsresultate im Hinblick auf das optimale RT- Schema.

Methoden

Untersucht wurden 45 Patienten, welche zwischen 2005 und 2017 wegen primärer Non-ependymomaler-Rückenmarksgliome mittels RT behandelte wurden: 37 (82 %) waren postoperativ, 6 (13 %) waren definitiv bestrahlt worden, 2 (5 %) haben aufgrund von Tumorrezidiven eine Salvage-RT erhalten. 4 Patienten mit zum Diagnosezeitpunkt bereits metastasierten Tumoren haben eine kraniospinale Bestrahlung („craniospinal irradiation“) erhalten. Die übrigen Patienten waren allein lokal bestrahlt worden (Median 50,4 Gy).

Ergebnisse

In 23 Fällen kam es zu einem Therapieversagen (bei 20 Patienten ohne Metastasierung zum Diagnosezeitpunkt und bei 3 Patienten mit Metastasen zum Diagnosezeitpunkt welche mit CSI behandelt wurden). Die Zweijahresgesamtüberlebensrate und die krankheitsfreie Überlebensrate betrugen 74 bzw. 54 %. Insgesamt traten zu Beginn oder im Verlauf in 13 Fällen (32 %) neue Metastasen außerhalb des Bestrahlungsfeldsauf. Das Tumorgrading korrelierte signifikant mit den Überlebensendpunkten (p = 0,009; 0,028) und der Gesamtaussaatrate (p = 0,042). Bei G2‑Tumoren entwickelten sich in 23 % Absiedlungen mit sehr ungünstiger Prognose (Median 10 Monate nach RT), bei G3‑Tumoren kam es bei 45 % zu einer Streuung mit unterschiedlicher Prognose. Patienten mit G4‑Tumoren entwickelten in 45 % Metastasen, die Überlebensraten bei neu auftretenden Metastasen waren deutlich geringer (Zweijahresüberlebensrate 50 %, p < 0,001).

Schlussfolgerung

Aufgrund der hohen Metastasierungsrate bei Rückenmarksgliomen mit hohem Grading und ungünstigen Merkmalen sollte eine intensivierte Therapie wie etwa eine prophylaktische CSI erwogen werden. Eine prophylaktische CSI könnte eine Option zur Verlängerung des Überlebens sein und erfordert eine prospektive Validierung.
