Metastatik Beyin Tümörlü Olgularda Tümörün Özellikleri ve Tümör Cerrahisinin Sağkalım Üzerine Etkilerinin Retrospektif Olarak Analizi: Tek Merkezli Çalışma

Yıl 2025, Cilt: 10 Sayı: 3, 86 - 92, 31.12.2025

Öz

Amaç: Metastatik beyin tümörleri; günümüzde insidansı sürekli artmakta olan ciddi morbidite ve mortaliteye neden olabilecek patolojiler arasındadır. Kliniğimizde opere olmuş metastatik beyin tümürlü olguların demografik özellikleri, lezyonun primer kaynaklandığı odağı, metastaz sayısı ve lokalizasyonunu retrospektif olarak inceleyerek morbidite ve mortalite üzerine etkisini tartışmayı amaçladık.

Gereç ve Yöntemler: Bu çalışmada retrospektif olarak kliniğimizde 01.01.2022-31.12.2024 tarihleri arasında intrakranial kitle nedeni opere edilen ve metastatik beyin tümörü tanısı almış olguların demografik özellikleri, metastatik tümörünün ve kliniğinin verileri toplandı. Sonuçlar istatistiksel olarak analiz edildi. P<0.05 anlamlı kabul edildi.

Bulgular: Çalışmada toplam 67 hasta yer almaktadır. Hastaların yaş ortalaması 63 ± 10 yıldır. Çalışma grubunda erkek hastalar (51 kişi, %76,12), kadın hastalara (16 kişi, %23,88) göre belirgin çoğunlukta idi. En sık görülen tümör yerleşimi pariyetal bölge (22 kişi, %32,83) olarak dikkat çekmektedir. Bunu 2. sıklıkta frontal lob tümörleri (15 kişi, %22,39) ve serebellar bölge tümörleri (15 kişi, %22,39) takip etmektedir. Hastaların büyük çoğunluğunda cerrahi endikasyonu olan tek bir metastaz (49 hasta, %73,13) bulunmaktadır. Beyin metastazlarının birincil kaynağı incelendiğinde, akciğer kanseri (37 hasta, %55,22) açık ara en yaygın neden olarak öne çıkmaktadır. Meme kanseri (%8,96) ve böbrek kanseri (%7,46) de diğer önemli primer kaynaklardır. Hastalara çoğu cerrahi olarak subtotal rezeksiyon (%62,69) yapılmıştır. Hastaların çoğunluğunda, preoperatif döneme göre ek bir morbidite veya nörolojik defisit gözlenmemiştir (59 kişi, %88,06). 14 hasta (%20,9) neoplazma kaynaklı exitus olurken, bunlardan 8 tanesi (%11,94) postoperatif dönemde exitus olmuştur.

Sonuç: Metastatik beyin tümörlerinde, metastazın yerleştiği lokalizasyon, cerrahi olarak lezyonun total ya da subtotal çıkarılması tümör kaynaklı hastanın sağkalımı ve mortalitesinde önemli bir yer edinmektedir.

Objective: Metastatic brain tumors are among the pathologies that can cause serious morbidity and mortality with an increasing incidence. We aimed to retrospectively examine the demographic characteristics, primary origin of the lesion, number and localization of metastases in patients with metastatic brain tumors operated in our clinic and to discuss their effects on morbidity and mortality.

Materials and Methods: In this study, we retrospectively collected demographic characteristics, metastatic tumor and clinic data of patients who were operated for intracranial mass and diagnosed with metastatic brain tumor between 01.01.2022-31.12.2024 in our clinic. The results were analyzed statistically. P<0.05 was considered significant.

Results: A total of 67 patients were included in the study. The mean age of the patients was 63 ± 10 years. In the study group, male patients (51 patients, 76.12%) were significantly more common than female patients (16 patients, 23.88%). The most common tumor location was the parietal region (22 patients, 32.83%). This was followed by frontal lobe tumors (15 patients, 22.39%) and cerebellar region tumors (15 patients, 22.39%). The majority of patients had a single metastasis (49 patients, 73.13%) for which surgery was indicated. When the primary source of brain metastases is analyzed, lung cancer (37 patients, 55.22%) is by far the most common cause. Breast cancer (8.96%) and kidney cancer (7.46%) were other important primary sources. Most patients were surgically treated with subtotal resection (62.69%). The majority of patients had no additional morbidity or neurologic deficit compared to the preoperative period (59 patients, 88.06%). While 14 patients (20.9%) had neoplasm-induced exitus, 8 of them (11.94%) had exitus in the postoperative period.

Conclusion: In metastatic brain tumors, the localization of the metastasis and total or subtotal surgical removal of the lesion play an important role in the survival and mortality of the patient with tumor origin.
