MSS Kolon Kanseri Tedavisinde Kemoterapi ile Birlikte Neoadjuvan Tislelizumab

Sade dilde özet

Bu çalışma, mikrosatellit kararlı (MSS) kolon kanseri (colon cancer) olan hastalarda ameliyat öncesi (neoadjuvan) Tislelizumab ile kemoterapinin (Oxaliplatin ve Capecitabine) birlikte kullanımını değerlendirmektedir. Çalışmaya 18-75 yaş arası, T4 veya lenf nodu tutulumu olan, uzak yayılımı bulunmayan MSS kolon adenokarsinomu hastaları katılmıştır. Faz 2 aşamasında yürütülmekte; şu an katılımcı almamakta ancak devam etmektedir (active, not recruiting).
