Özet

Acute lymphoblastic leukemia (ALL) is the most common type of cancer in children. The identification of prognostic factors has become essential in design and analysis of modern therapeutic trials. The aim of this study is to present the expression patterns of lamin A/C, lamin B1 and B2 and their prognostic value in childhood acute lymphoblastic leukemias, which are thought to be related with cell proliferation and apoptosis. The study was carried out between January 2008 and March 2014 at the Cukurova University Faculty of Medicine, Division of Pediatric Oncology and sixty-four patients diagnosed with ALL and 35 control cases were included in the study. Real Time-Polymerase Chain Reaction (RT-PCR) method was used to detect lamin A/C, lamin B1 and lamin B2 protein expression at the time of the diagnosis and at the end of the induction treatment. At the time of the diagnosis, lamin B1 protein gene expression was lower in ALL patients when compared to the control group (p= 0.001). When lamin gene expression levels at the time of diagnosis and after induction therapy were compared, the lamin A/C and B2 gene expressions were significantly lower after the administration of induction chemotherapy (both values p= 0.0001). The decrease in lamin B1 gene expression was not statistically significant (p= 0.403). When the lamin expression levels in the control group were compared with the levels after induction chemotheraphy, lamin expressions were found to be significantly lower (all p values 0.0001). In childhood ALL, lamin B1 protein gene expression could be used as a diagnostic marker, while decrease in the lamin A/C and B2 protein gene expressions after induction could be used as a marker for response to therapy. Our study is the first to show in lamin protein gene expression relationship with diagnosis and prognosis in ALL in literature. Comprehensive multicenter studies are needed with a larger cohort of patients to reach more reliable results.

Abstract

Akut lenfoblastik lösemi (ALL), çocuklarda en sık görülen kanserdir. Prognostik faktörlerin tanımlanması, modern tedavi denemelerinin tasarımı ve analizi için önemlidir. Bu çalışmanın amacı çocukluk çağı ALL’lerinde lamin A/C, lamin B1 ve lamin B2 proteinlerinin gen ekspresyon durumunun saptanması ve prognoz ile olan ilişkilerinin değerlendirilmesidir. Akut lenfoblastik lösemi tanısı alan 64 hasta ve 35 kontrol olgu çalışmaya dahil edildi. Tanı anında ve indüksiyon kemoterapisi bitiminde lamin A/C, lamin B1 ve lamin B2 protein gen ekspresyonları Real Time PCR yöntemi ile çalışıldı.ALL hastalarımızda, tanı anında bakılan lamin B1 protein gen ekspresyonu kontrol grubuna göre belirgin olarak düşük bulundu (p= 0,001). Tanı anındaki lamin protein gen ekspresyonu düzeyleri ile indüksiyon kemoterapisi sonrasında bakılan lamin protein gen ekspresyonu düzeyleri karşılaştırıldığında; indüksiyon kemoterapisi verildikten sonra lamin A/C ve B2 protein gen ekspresyon düzeylerinin anlamlı olarak azaldığı görülmüştür (her iki değeri p= 0.0001). Lamin B1 protein gen ekspresyon düzeyindeki azalmanın ise anlamlı olmadığı görülmüştür (p:0,403). Kontrol grubu ile indüksiyon kemoterapisi sonrasındaki lamin düzeyleri karşılaştırıldığında ise tüm lamin protein gen ekspresyon düzeylerinde anlamlı bir azalma saptanmıştır (tüm p değeri 0.0001 idi). Çocukluk çağı akut lenfoblastik lösemilerinde, lamin B1 protein gen ekspresyonu, tanısal bir belirteç olarak, lamin B2 protein gen ekspresyonu ise prognostik bir belirteç olarak kullanılabilir.
