MEME KANSERİNDE HORMON RESEPTÖRÜ SAĞKALIM VE METASTAZ ÜZERİNDE BELİRLEYİCİDİR

Öz

Triple Negatif TN meme kanseri sınırlı tedavi alternatiflerine sahiptir. Bu grupta tedavinin fayda şansı azdır. Prognoz kötüdür ve diğer tiplere nazaran daha saldırgan seyirlidir. Daha fazla aksiller lenf nodu tutulumu, erken dönemde ve özellikle iç organlara erken metastaz karakteristiktir. Az sayıda tedavi alternatifine sahip TN meme kanseri aralarındaki farklılıkların da ortaya konulabilmesi için yeni tedavi protokollerinden fayda gören Luminal B LB meme kanseri ile kıyaslanmıştır. Bu iki grup arasındaki farklılıkların ortaya konması ümit vadeden tedavilerin oluşturulabilmesi ve takip stratejilerinin geliştirilebilmesine yardımcı olabilir. Bu çalışmaya Ege üniversitesi Genel Cerrahi Servisinde 1998 ile 2007 yılları arasında bilinen metastazı olmayan 91 TN östrojen reseptör negatif, progesteron reseptör negatif ve insan epidermal büyüme faktör reseptörü 2 negatif ve 183 Luminal B östrojen reseptör pozitif, progesteron reseptör pozitif ve insan epidermal büyüme faktör reseptörü 2 pozitif hasta dâhil edilmiştir TN grubunda metastazsız sağkalım oranları 12 ve 24. aylarda LB gruba nazaran daha düşük olmasına rağmen istatistiksel olarak anlamlı değildi. Bununla birlikte 36 Log Rank p=0.021 ve 60. Log Rank p=0.041 aylarda anlamlı bir fark bulundu. TN fenotipi erken zamanda artmış iç organ metastaz riski nedeni ile prognozda negatif etki göstermektedir. Bu bulgu takip ve tedaviye yaklaşımda stratejik bir değere sahiptir

HORMONE RECEPTOR STATUS DEFINES SURVIVAL AND METASTASIS RATE IN BREAST CANCER

Abstract

Triple Negative TN breast cancer has few treatment alternatives. The chance for cure is poor, prognosis is bad and it is more aggressive than other types of breast cancers. Axillary involvement and early solid organ metastasis especially internal organs are more frequent. TN breast cancer with less treatment alternative was compared to divulge the differences with Luminal B LB which showed better outcomes with new treatment protocols. Comparison of these two groups may help us to produce promising treatment and follow up protocols. In Ege University General Surgery Department 91 TN estrogen negative, progesterone negative and human epidermal growth factor negative and 183 LB estrogen positive, progesterone positive and human epidermal growth factor positive patients operated between 1998 and 2007 were included in this study Survival without metastasis were lower than in TN group than LB group at 12th and 24th months but these were statistically indifferent. At 36th and 60th months however differences were significant Log Rank p=0.021 and p=0.041 respectively TN phenotype has negative prognosis due to the effect of early high internal organ metastasis rate. This finding has a strategic importance in treatment and follow up approach
