Abstract
Amaç: Çalışmamızda, merkezimizde hematopoetik kök hücre
nakli (HKHN) yapılan çocuk hastalarda santral sinir sistemi (SSS)
komplikasyonları ve pozitif radyolojik bulguların sağkalıma etkisinin değerlendirilmesi amaçlandı.
Gereç ve Yöntem: Çalışmaya Ağustos 1998-Ocak 2014 yılları
arasında merkezimizde HKHN yapılan 489 olgudan, nakil dönemi veya sonrasında nörolojik bulgu gelişen ve nöroradyolojik
görüntüleme yapılan 91 (%18,6) olgu alındı. Veriler geriye dönük
olarak incelendi.
Bulgular: Olgular, radyolojik bulgu saptanan ve saptanmayan
olmak üzere iki gruba ayrıldı. Kırk yedi (%51,6) olguda radyolojik bulgu saptanırken, 44’ünde (%48,3) radyolojik bulgu saptanmadı. Radyolojik bulgusu pozitif ve negatif olgularda SSS
komplikasyonlarına bağlı ölüm oranları karşılaştırıldı ve radyolojik
bulgu pozitif olgularda SSS komplikasyonuna bağlı kaybedilme
oranı anlamlı olarak daha fazla saptandı (p=0,015). Radyolojik
bulgu varlığına göre genel sağkalım süresi değerlendirildiğinde
radyolojik bulgu saptanan grupta 30,5±4,5 ay, radyolojik bulgu
saptanmayan grupta ise 68,6±10,1 ay olarak hesaplandı. Radyolojik bulgu varlığının sağkalım sürelerini anlamlı olarak azaltmakta olduğu saptandı (p=0,046). Saptanan radyolojik bulgular
serebrovasküler komplikasyonlar (kanama, iskemi, enfarkt), beyaz
cevher tutulumu (posterior reversibl ensefalopati sendromu dahil)
ve enfeksiyonlar olarak 3 gruba halinde incelendiğinde, en düşük sağkalım sürelerinin serebrovasküler komplikasyon grubunda
olduğu görüldü (p=0,016).
Sonuç: HKHN yapılan olgularda nörolojik komplikasyonlar nadir
değildir. Bu olgularda nöroradyolojik değerlendirme mümkün olduğunca erken dönemde yapılmalıdır. Bu olguların yönetiminde
radyolojik pozitif bulgu varlığının, özellikle serebrovasküler komplikasyonlara ait pozitif radyolojik bulguların sağkalımı belirgin
derecede azaltabileceği göz önünde bulundurulmalıdır
Purpose: We evaluated the relation between positive radiological findings and patient survival among patients who had HSCT in our institution. Material and Methods: We retrospectively evaluated records of all the patients who had HSCT between August 1998-January 2014 in our institution. There were total 489 patients who had HSCT in this period and 91 (18.6%) of them had developed neurologic symptoms and neuroradiologic evaluation. Results: Forty-seven (51.6%) patients had positive findings and 44 (48.3%) patients had no radiologic findings. In the patients with positive radiologic findings, the ratio of death due to neurologic complications was significantly higher than the patients with no radiologic findings (p=0.015). In the group of patients with positive findings, mean survival was 30.5±4.5 months, whereas in patients with no findings, mean survival was 68.6±10.1 months. The presence of radiologic findings was significantly decreasing the mean survival (p=0.046). When the findings were divided into three groups as cerebrovascular complications (bleeding, ischemia and infarction), white matter involvement (including posterior reversible encephalopathy syndrome) and infections, the shortest mean survival was in the cerebrovascular complication group (p=0.016). Conclusion: Neurologic complications are not rare in patients who had HSCT. In these patients, prompt neuroradiologic evaluation is mandatory. In the management of these patients, it should always be kept in mind that positive neuroradiologic findings may considerably shorten the patients’survival.
