Abstract

Amaç: Akut myeloid lösemili olguların bir kısmı lökositoz ve hatta eşlik eden lökositaz bulguları ile başvurmaktadır. Hiperlökositoz ve lökositaz bulguları olan hastalarda indüksiyon tedavisi öncesi sitoredüktif tedavi rutin pratikte uygulanan bir yöntemdir. Bu çalışmada; hiperlökositoz ile başvuran akut myeloid lösemili olgularda hidroksiüre sitoredüksiyon tedavisi ile hidroksiüre/lökoferez/steroid sitoredüksiyon tedavilerinin karşılaştırılması amaçlanmıştır.
Materyal Metod: Çalışmaya hiperlökositoz bulgusu ile başvuran 40 akut myeloid lösemili olgu alınmıştır. Hastaların dosya bilgileri geriye dönük taranmış ve demografik özellikleri ile aldıkları sitoredüktif tedaviler belirlenmiştir. Kırk hastadan 30’una hidroksiüre sitoredüksiyon tedavisi, 10 hastaya ise hidroksiüre/lökoferez/steroid sitoredüksiyon tedavileri verilmiştir.
Bulgular: Hastaların ortanca yaşı 48,5 / yıl (en düşük-en yüksek: 18-75/yıl) idi. Altmış yaş altında 30 (%75) hasta, 60 yaş üstünde 10 (%25) hasta vardı. Yirmibir (% 52,5) hasta erkek, 19 (%47,5) hasta kadın idi. Hastaların başvuru anındaki beyaz küre değerlerinin ortancası 86.x109/L (düşük/yüksek: 50.x109/L -300.x109/L) idi. Sitoredüksiyon tedavisi sonrası hastaların beyaz küre değerinin ortancası 71.x109/L (düşük/yüksek: 38.x109/L -95.x109/L) idi. Tanı anında yapılan kemik iliği aspırasyonundaki blast oranı ortanca %82,75 (düşük/yüksek;%20-%100) idi. Sitoredüksiyon ve birinci indüksiyon sonrası yapılan kontrol kemik iliği aspırasyonundaki blast oranlarının ortancası %5,12 (düşük/yüksek;%0-%100) idi.Hidroksiüre/lökoferez/steroid alan kolda sadece hidroksiüre alan kola göre beyaz küre değerlerinin daha iyi kontrol altına alındığı görüldü (p:0,001). Ancak sitoredüksiyon tedavi kollarından hiçbirinin kemik iliğinde blast oranını azaltması yönünde anlamlı ilişkisi olmadığı tespit edildi (p: >0,05).
Sonuç: Hidroksiüre/ lökoferez/steroid kolunun sadece hidroksiüre koluna göre çevre kanı beyaz küre sayısını daha etkin düşürdüğü sonucuna varılmıştır.

A Retrospective Comparison of Leukapheresis, Hydroxyurea and Steroid Therapies in Patients with Acute Myelocytic Leukemia who Present with Hyperleukocytosis

Abstract

Background: Some of the cases with acute myeloid leukemia present with hyperleukocytosis and even accompanying leukocytosis. Cytoreductive therapy is a routine practice method in patients with hyperleukocytosis and leukocytosis before induction therapy. In this study; We aimed to compare hydroxyurea cytoreduction treatment with hydroxyurea / leukapheresis / steroid cytoreduction treatments in patients with acute myeloid leukemia presenting with hyperleukocytosis.
Materials and Methods: Forty patients with acute myeloid leukemia who admitted to the study with evidence of hyperleukocytosis were included. Patients' file information was retrospectively scanned and their demographic characteristics and cytoreductive treatments were determined. Hydroxyurea cytoreduction treatment was given to 30 of the forty patients and hydroxyurea / leukapheresis / steroid cytoreduction treatments were given to 10 patients.
Results: The median age of the patients was 48.5 / year (minimum-maximum: 18-75 / year). There were 30 (75%) patients under the age of 60 and 10 (25%) patients above the age of 60. Twenty-one (52.5%) patients were male and 19 (47.5%) patients were female. The median of the patients' white blood cell count at admission was 86x109 / L (low / high: 50x109 / L -300x109 / L). After cytoreduction treatment, the median of the white blood cell count of the patients was 71x109 / L (low / high: 38x109 / L -95x109 / L). The median blast rate in bone marrow aspirate performed at the time of diagnosis was 82.75% (low / high; 20% -100%). The median of blast rates in control bone marrow aspirate performed after cytoreduction and first induction was 5.12% (low / high; 0% -100%). was seen (p= 0.001). However, it was found that none of the cytoreduction treatment arms had a significant relationship in terms of decreasing the blast rate in the bone marrow (p > 0.05).
Conclusion: It was concluded that the hydroxyurea / leukapheresis / steroid arm reduced the peripheral white blood cell count more effectively than the hydroxyurea arm.
