RAS/BRAF Genleri Yaban Tip Olan Metastatik Sol Taraflı Kolorektal Kanser İçin Birinci Basamak mCapOX+Setuksimab ve mFOLFOX6+Setuksimab Karşılaştırması

Sade dilde özet

Bu çalışma, RAS ve BRAF genleri yaban tip (wild-type) olan metastatik sol taraflı kolorektal kanser (colorectal cancer) hastalarında birinci basamak tedavi olarak mCapOX artı Setuksimab (cetuximab) ile mFOLFOX6 artı Setuksimab tedavilerini karşılaştırmaktadır. Çalışmaya, 18 yaş ve üzeri, doku tanısı doğrulanmış ve daha önce palyatif tedavi almamış hastalar alınmaktadır. Faz 2 aşamasında yürütülmekte ve halen katılımcı almaktadır.
