Özet
Meme kanseri, kadınlarda en sık görülen kanser türüdür. Tedavisindeki ilerlemeler sağkalım sürelerini uzatmış, bu da metastaz insidansını artırmıştır. Meme kanserine bağlı ölümlerin başlıca nedeni uzak organ metastazları olup, beyin metastazı insidansı bakımından ikinci en sık solid organ tümörü olarak dikkat çekmektedir. Çalışmamızda Bursa Uludağ Üniversitesi Tıbbi Onkoloji Polikliniğine 01.01.2018-31.12.2023 tarihleri arasında tarihleri arasında başvuran patolojik olarak meme kanseri tanısı olup MRG veya BT görüntülemesi ile beyin metastazı eşlik eden 90 hastanın klinik ve patolojik özelliklerinin beyin metastazı gelişim süresi, beyin metastazı sonrası sağkalım ve genel sağkalımlarını etkileyen faktörler retrospektif olarak araştırıldı. Beyin metastazı gelişim süresi üzerinde incelenen 24 parametreden 3’ü tek değişkenli analizlerde anlamlı bulunmuştur. Bu anlamlı değişkenler; meme kanseri tanı anında ileri evre olması, performans skorunun iki ve üstü olması, östrojen reseptörün negatif olması kötü prognostik faktör olarak tespit edilmiştir (sırasıyla, p<0,001, p=0,005 ve p=0,035). Beyin metastazı sonrası sağkalım süresine etkisi incelenen 23 parametreden yedisi tek değişkenli analizlerde etkili bulunmuş, olup yapılan çok değişkenli analizde beyin metastazı sonrası sistemik tedavi alımı ile beyin metastazı saptandığında ikiden düşük performans skoru olmasının beyin metastazı sonrası uzun sağkalımla ilişkilendirilerek bağımsız prognostik faktörler olduğu tespit edilmiştir (sırasıyla, p<0,001, p<0,001). Genel sağkalım süresi üzerinde incelenen 21 parametreden 3’ü tek değişkenli analizlerde ekili bulunmuş olup yapılan çok değişkenli analizde meme kanseri tanı anı performans skorunun 2 veya üstü olması ile lenf nodu tutulumu varlığı kısa genel sağkalımla ilişkilendirilerek bağımsız prognostik faktörler olduğu tespit edilmiştir (sırasıyla, p<0,001, p=0,010).
Breast cancer is the most common type of cancer in women. Advances in its treatment have prolonged survival times, which has consequently increased the incidence of metastasis. Distant organ metastases are the primary cause of breast cancer-related deaths, and in terms of brain metastasis incidence, breast cancer stands out as the second most common solid organ tumor. In our study, we retrospectively analyzed the clinical and pathological characteristics of 90 patients diagnosed with breast cancer who presented to the Bursa Uludağ University Medical Oncology Outpatient Clinic between January 1, 2018, and December 31, 2023, and were found to have brain metastases through MRI or CT imaging. The study investigated factors affecting brain metastasis development time, post-brain metastasis survival, and overall survival. Among the 24 parameters examined concerning brain metastasis development time, three were found to be significant in univariate analyses. These significant variables were advanced stage at the time of breast cancer diagnosis, a performance score of two or higher, and negative estrogen receptor status, all of which were identified as poor prognostic factors (p<0.001, p=0.005, and p=0.035, respectively). Among the 23 parameters analyzed for their effect on survival after brain metastasis, seven were found to be significant in univariate analyses. In the multivariate analysis, receiving systemic therapy after brain metastasis and having a performance score below two at the time of brain metastasis detection were identified as independent prognostic factors associated with longer post brain metastasis survival (p<0.001, p<0.001, respectively). Among the 21 parameters examined for their effect on overall survival, three were found to be significant in univariate analyses. In the multivariate analysis, a performance score of two or higher at the time of breast cancer diagnosis and the presence of lymph node involvement were identified as independent prognostic factors associated with shorter overall survival (p<0.001, p=0.010, respectively).
