Abstract

Objective: This study aimed to compare the factors that are thought to affect the survival of patients who received radiotherapy to the metastatic bone in prostate cancers.
Material and Methods: The study included 92 patients who received radiotherapy for prostate cancer bone metastasis.
Results: While death was observed with a rate of 57.1% in patients aged ≤70 years, this rate was determined as 74% in patients aged >70 years. Although there was no statistically significant difference in comparing these values, it was observed that patients aged >70 years tend to have a 2.135 times higher risk of death compared to patients aged ≤70 years (p>0.05). When the survival of patients with visceral organ metastasis and bone metastasis was compared with those with only bone metastasis, a statistically significant result was observed (p<0.01). While all (100%) patients who had bone metastasis with lung metastasis and had bone metastasis with liver metastasis died, the mortality rate decreased to 49.2% in patients with only bone metastasis. The relationship between the radiotherapy portal and mortality was not statistically significant.
Conclusion: A patient’s visceral organ metastasis, marital status, Gleason score at the time of diagnosis, age, and weight affect the survival of patients with prostate cancer treated with radiotherapy to the metastatic bone.

Prostat Kanseri Kemik Metastazına Radyoterapi Uygulanan Hastalarda Sağ Kalımı Etkileyen Faktörler

Abstract

Amaç: Bu çalışmada, prostat kanserlerinde metastatik kemiğe radyoterapi uygulanan hastalarda sağ kalım üzerine etkili olabileceği düşünülen faktörlerin karşılaştırılması amaçlanmıştır.
Gereç ve Yöntemler: Prostat kanserinin kemik metastazı nedeniyle radyoterapi almış olan 92 hasta çalışmaya dahil edilmiştir.
Bulgular: Yetmiş yaşından küçük hastalarda %57.1 oranında ölüm gözlenirken, >70 yaş hastalarda bu oran %74 olarak belirlenmiştir. Bu değerlerin karşılaştırılmasında her ne kadar istatistiksel olarak anlamlı fark görülmese de >70 olan hastaların ≤70 hastalara göre ölüm riskinin 2.135 kat daha yüksek olma
eğiliminde olduğu gözlenmiştir (p>0.05). Visseral organ metastazı ile birlikte kemik metastazı olan hastalarla, yalnız kemik metastazı olan hastaların sağ kalımı karşılaştırıldığında istatistiksel olarak anlamlı sonuç bulunmuştur (p<0.01). Akciğer metastazı ile birlikte kemik metastazı olan ve karaciğer metastazı
ile birlikte kemik metastazı olan hastaların hepsi (%100) ölmüştür, yalnız kemik metastazı olan hastalarda ise ölüm oranı %49.2’ye düşmüştür. Radyoterapi sahası ile ölüm oranı arasındaki ilişki istatistiksel olarak anlamlı bulunmamıştır.
Sonuç: Hastanın visseral organ metastazı, evlilik durumu, tanı anındaki Gleason skoru, yaşı ve kilosu metastatik kemiğe radyoterapi uygulanan prostat kanserli hastaların sağ kalımını etkilemektedir.
