İnfantil hemanjiomların tedavisinde topikal beta-blokerlerin etkinliği

Abstract

ÖZET Amaç: İnfantil hemanjiomlar (İH) endotel hücrelerinin benign proliferasyonlarıdır. Çocukluk çağının en sık görülen benign tümörleridir. İH’ın çoğu kendiliğinden gerilerken, yaklaşık %10'u medikal tedavi gerektirir. İH’ın medikal tedavisinde kortikosteroidler, interferon ve vinkristin eskiden beri kullanılan ajanlardır. Son yıllarda topikal beta-blokörler teröpatik etkinliklerinin gösterilmesi ve sistemik yan etkilerin daha az görülmesi nedeniyle IH tedavisinde alternatif bir tedavi yöntemi olarak kullanılmaya başlanmıştır. Bu çalışmada, topikal beta-bloker kullanılan yüzeyel İH hastalarının epidemiyolojik özellikleri ve tedavi etkinliğinin değerlendirilmesi amaçlanmıştır. Gereç ve yöntem: Erzurum Bölge Eğitim ve Araştırma Hastanesi Çocuk Hematoloji-Onkoloji polikliniğine Nisan 2015 ile Mayıs 2017 tarihleri arasında başvuran, yaşları 0-36 ay arasında olan 30 hasta çalışmaya dahil edildi. Yüzeyel hemanjiyomu olan hastalara lezyon bölgesine %0,5 timolol maleate solüsyon, sabah ve akşam ikişer damla olacak şekilde uygulandı. Bulgular: Tedavi öncesi hemanjiomların çapı ortalama 2,5 ± 1,5 cm iken, tedavi sonrası 1,3 ± 0,8 cm olarak belirlendi (p<0,0001). Sonuç: Lezyonda belirgin gerilemeye yol açması nedeni ile timolol kullanımı ümit vadetmektedir. Ancak daha geniş çaplı ve kontrollü-randomize çalışmalara ihtiyaç olduğu da bir gerçektir. ABSTRACT Aim: Infantile hemangiomas are benign proliferation of endothelial cells. It is the most common benign tumor of childhood. Most of the IH is spontaneously regressing, and about 10% requires medical treatment. Corticosteroids, interferon and vincristine have long been used in medical treatment of IH. In recent years, topical beta-blockers have been used as an alternative treatment modality for the treatment of IH because of their therapeutic efficacy and low systemic side effects. The aim of this study was to evaluate the epidemiological features and treatment efficacy of superficial IH patients using topical beta-blockers. Materials and Methods: For this purpose, 30 patients, aged between 0-36 months, who applied to the Pediatric Hematology-Oncology Polyclinic of the Erzurum Regional Education and Research Hospital between April 2015 and May 2017 were included in the study. In patients with superficial hemangioma, 0,5 % timolol maleate solution was applied to the lesion area, two drops in the morning and in the evening. Results: The mean diameter of the hemangiomas before treatment was 2.5 ± 1.5 cm and 1.3 ± 0.8 cm after the treatment. (P<0,0001). Conclusıons: The use of timolol is promising because it causes a marked regression in the lesion. However, it is a fact that wider-scale and controlled-randomized studies are needed.

Abstract

Abstract
Purpose: Infantile hemangiomas are benign proliferation of endothelial cells. It is the most common benign
tumor of childhood. While the most of IH is spontaneously regressing, about 10% requires medical treatment.
Corticosteroids, interferon and vincristine have long been used in medical treatment of IH. In recent years,
topical beta-blockers have been used as an alternative treatment modality for the treatment of IH because of
their therapeutic efficacy and low systemic side effects. The aim of this study was to evaluate the epidemiological
features and treatment efficacy of superficial IH patients using topical beta-blockers.
Materials and methods: 30 patients, aged between 0-36 months, who applied to the Pediatric HematologyOncology Polyclinic of the Erzurum Regional Education and Research Hospital between April 2015 and May
2017 were included in the study. In patients with superficial hemangioma, 0.5% timolol maleate solution was
applied to the lesion area, two drops in the morning and in the evening.
Results: While the mean diameter of hemangiomas before treatment was 2.5±1.5 cm, it was determined as
1.3±0.8 cm after treatment (p<0,0001).
Conclusions: The use of timolol is promising because it causes a marked regression in the lesion. However, it
is a fact that wider-scale and controlled-randomized studies are needed.
