Abstract

The immunophenotypes of 21 patients with newly diagnosed acute lymphocytic leukemia (ALL) (medyan age, 29 years [18-78]) have been reviewed. All patients received standard induction therapy consisting of vincristine, daunomycine and prednisone. Fourteen patients achieved complete remission (CR). Five patients at high risk received an alternating intensification regimen (with vepeside/cytosine arabinoside and cyclophosphamide / vincristine / daunomycine / prednisone arms) after achieving remission. We observed no relapses in these patients. Among the remaining nine patients who did not receive the alternating intensification regimen 7 relapses occurred. Eight patients were CD34(-) and 13 patients were CD34(+). All patients with refractory disease were CD34(+) (p0.05). Two year overall survival estimation in CD34 (+) group was significantly lower than CD34(-) group (17% and 100%, respectively) (p

Özet

Akut lenfositik lösemi (ALL) tanısı alan 18-78 yaşları arasında (medyan 29) 21 yeni tanı almış hastanın immünfenotipik özellikleri incelendi. Tüm hastalar vinkristin, daunomisin, prednizondan oluşan standart indüksiyon tedavisi aldı. 14 hasta standart indüksiyon tedavisi ile remisyona girdi. Yüksek riskte olan 5 hastaya remisyon sonrası intensifikasyonda alterne kemoterapi şeması (vepesid/sitozin arabinozid ve siklofosfamid/vinkristin/daunomisin/prednizon) uygulandı. Standart indüksiyon ile tam remisyona ulaşan ve alterne rejim ile intensifikasyon tedavisi uygulanmayan 9 hastanın 7'sinde nüks gözlendi. Alterne rejim ile intensifikasyon alan grupta ise nüks gözlenmedi. Sekiz hasta CD34 (-), 13 hasta CD34 (+)'ti. Dirençli hastalığı olan tüm hastalar CD34 pozitifti (p0.05). İki yıllık tahmini sağ kalım süreleri kıyaslandığında CD34(+) grubun sağ kalım sürelerinin CD34(-) gruba göre belirgin olarak düşük olduğu görüldü (sırasıyla %17 ve %100) (p
