Tedavi alanındaki tüm gelişmelere rağmen, akciğer kanseri hala
tüm dünyada kanserle ilişkili ölüm nedenlerinin başında gelmektedir.
Etyolojisinde sigaranın yanı sıra çevresel, mesleksel ve genetik
faktörler rol oynamaktadır. Akciğer kanserleri genellikle kü-
çük hücreli akciğer kanseri (KHAK) ve küçük hücreli dışı akciğer
kanseri (KHDAK) olmak üzere iki ana histolojik tipe ayrılır. Tüm
akciğer kanserlerinin yaklaşık %85’ini oluşturan KHDAK’inde bir-
çok gen anomalisi saptanır. Anaplastik lenfoma kinaz (ALK) geni
insülin reseptör tirozin kinaz süper ailesinin bir üyesidir. ALK geni
akciğer kanseri, lenfoma gibi çeşitli malignitelerde füsyon protein
oluşumuna yol açan translokasyonlara dahil olur. Bu derlemede
KHDAK’inde görülen ALK yeniden düzenlenmelerine ait son literatür
gözden geçirilecektir.

Anahtar Kelimeler

akciğer kanseri; küçük hücreli dışı akciğer kanseri; ALK geni; gen yeniden düzenlenmeleri; EML4/ALK füzyon

Importance of Anaplastic Lymphoma Kinase Gene Re-arrangements on Non-Small Cell Lung Cancer

Öz

Despite all improvements in treatment modalities, lung cancer
is the leading cause of death related to cancers worldwide.
Environmental, occupational and genetic factors, as well as smoking
play role in the etiology. Lung cancers are generally divided
into two main histologic categories: small cell lung cancer (SCLC)
and non-small cell lung cancer (NSCLC). Several gene aberrations
are detected in NSCLC, which constitute approximately 85% of
all lung cancers. The Anaplastic lymphoma kinase (ALK) gene is a
member of insulin receptor tyrosine kinase super family. ALK gene
involves with translocation those results in formation of fusion protein
in various malignancies such as lung cancer and lymphoma. In
this article, latest literature regarding re-arrangement of ALK seen
in NSCLC will be reviewed.
