Abstract

Amaç: Bu çalışmada lokal ileri evre rektum tümörlü olgularda preoperatif
kemo-radyoterapi (KRT) sonrası klinik, radyolojik patolojik özelliklerin radyolojik
ve patolojik yanıt ile korelasyonunun araştırılması amaçlandı.



Gereç
ve Yöntem
: Çalışmada Ocak 2012
ve Mayıs 2017 tarihleri arasında endoskopik biyopsi ile rektum kanseri tanısı
alan ve kliniğimizde neoadjuvan (KRT) uygulanan 26 hasta retrospektif olarak
değerlendirildi. Hastaların tedavi öncesi endoskopik bulguları (dentat çizgiye
uzaklık, çevresel tutulum, ülserasyon), radyolojik tümör boyutu, Pozitron
Emisyon tomografi (PET) de görülen kitle boyutu, lenf nodu pozitifliği, standart
uptake değeri (SUV) düzeyi ile tedavi sonrası radyolojik ve patolojik yanıt
düzeylerinin ilişkisi araştırıldı. Patolojik regresyon düzeyi modifiye Ryan
skorlaması ile değerlendirildi.



Bulgular: Hastaların 19’u erkek 7’si kadın olup median yaşları 61
(40 – 83) idi. Olgularımızın medyan pelvik radyoterapi dozu 4500 cGy (3600 –
5040) tümöre yönelik boost dozu ise median 900 cGy (360 – 900) idi. Biri ileri
yaşta diğeri ise kardiak morbiditesi olan iki hastanın dışında tüm hastalara
radyoterapi eş zamanlı kapasitabin uygulandı. Kemoterapi sonrası yanıt tüm
hastalarda RECIST kriterlerine göre değerlendirildiğinde 1 hasta tam yanıtlı, 10
hasta stabil, kalan 15 hasta ise parsiyel yanıtlı olarak değerlendirildi. Tedavi
sonrası opere edilen 22 hastanın 11’ine abdominoperineal rezeksiyon (APR)
15’ine ise low anterior rezeksiyon (LAR) uygulandı. Radyoterapi sonrası
operasyona kadar geçen süre median 42 gün (15 – 194) olarak hesaplandı. Tedavi
öncesi PET CT de lenf nodu pozitif olan hastaların 11 inde patolojik lenf nodu
saptanmadı. Buna karşın başlangıçta lenf nodu görülmeyen 5 hastanın 1 inde
postop lenf nodu (+) idi. Endoskopide görülen tümörün çevreselliği,  lokalizasyonunun anal verge’den 5 cm ve daha
fazla olması ve radyolojik yanıt varlığı sfinkter koruma açısından anlamlı
bulunurken (sırasıyla p: 0,03, p:0,019 ve p:0,022), radyolojik yanıt üzerinde
incelenen hiçbir faktörün prediktif etkisi saptanmadı. Hastalar risk gruplarına
göre değerlendirildiğinde radyolojik ve patolojik yanıt üzerinde anlamlı bir
etki saptanmadı. 



Operasyon sonrası 1 hastada patolojik tam yanıt saptandı.
Regresyon skoru değerlendirilen 17 hastanın 2’sinde skor 3, 10’unda 2, 5
hastada ise 1 olarak değerlendirildi.



Sonuç: Tümörün çevresel yayılımı,  lokalizasyonunun anal verge’den 5 cm ve daha
yüksek olması ve radyolojik yanıt varlığı sfinkter koruma açısından anlamlı
bulunurken (sırasıyla p: 0,03, p:0,019 ve p:0,022), radyolojik yanıt üzerinde
incelenen hiçbir faktörün prediktif etkisi saptanmadı.
