Abstract

Amaç: Metastatik kolorektal kanserli hastalarda Regorafenib'in etkinliğini ve prognostik faktörlerini belirlemeyi amaçladık.
Gereç ve Yöntem: Bu çalışma tek merkezli ve retrospektif olarak tasarlandı. Çalışmaya Regorafenib ile tedavi edilen 72 metastatik kolorektal kanserli hasta dahil edildi. Sağkalımı etkileyen faktörlerin tek değişkenli ve çok değişkenli analizleri Cox Regresyon Modelleri ile oluşturuldu.
Bulgular: Hastaların yirmi üçü (%31,9) kadındı ve medyan yaş 65 idi. Hastalara ait medyan progresyonsuz sağkalım (PFS) ve toplam sağkalım (OS) sırasıyla 4,13 ay ve 8,7 aydı. Karsinoembriyonik antijen (CEA) seviyesi (p=0.001) ve Eastern Cooperative Oncology Group (ECOG) Skoru (p<0,001) PFS için çok değişkenli Cox-regresyon modelinde prognostik bulunmuştur. OS için yapılan çok değişkenli modelde ECOG (p<0,001), CEA (p<0,001), doz azaltımı (p=0,003), primer tümörün olduğu taraf (p=0,037) prognostik olarak bulundu.
Sonuç: Çalışmamız, ECOG skoru, tedavi sırasında doz azaltımı, ve daha düşük başlangıç CEA seviyelerinin OS için prognostik olduğunu ortaya koydu.

Prognostic factors influencing regorafenib treatment outcomes in metastatic colorectal cancer

Abstract

Aim: We aimed to determine the efficacy and prognostic factors of Regorafenib in advanced colorectal cancer patients.
Materials and Methods: This study was designed as single-center and retrospective. The study included 72 patients with metastatic colorectal cancer treated with Regorafenib. Univariate and multivariate analyses of factors affecting survival were generated by Cox Regression Models.
Results: Twenty-three (31.9%) of the patients were female, the median age was 65 years. The median progression-free survival (PFS) and overall survival (OS) were 4.13 and 8.7 months, respectively. The carcinoembryonic antigen (CEA) level (p=0.001), and Eastern Cooperative Oncology Group (ECOG) score (p<0.001) were found to be prognostic in the multivariate model for PFS. ECOG (p<0.001), CEA level (p<0.001), dose reduction (p=0.003), and side of the primary tumor (p=0.037) were prognostic for OS.
Conclusion: Our study revealed that ECOG, requiring dose reduction during the treatment, and lower baseline CEA levels were found to be prognostic.
