Dynamic Changes in RAS Gene Status and HER2 Expression in Circulating Tumour Cells: a Phase II Trial

Обзор

This multicenter study, randomized, controlled of blood-based biomarker-driven targhet therapy. Patients were selectedm( at Hospital San Giovanni and Celio in Rome) according to CTCs results ( CTCs-guided managment performed at University Magna Graecia) or managed by the treating clinician according to standard pathological criteria (standard management). The participants were assigned to trial groups with the use of block randomization stratified according to the enrolling center location metropolitan) and tumor stage (T3 or T4).

Подробное описание

The investigators enroll patients with histologically confirmed advanced stage (T3 or T4, N1/2, M0/1) colorectal adenocarcinoma with molecular analysis on RAS mutant status. The participants are enrolled within 3 weeks at the time of progression disease (PD) from any line of therapy. Blood samples were collected from each participant after obtaining informed consent. Permission to perform CTCs analysis from blood was obtained from the Regional Ethical Committee (No.2013/34) and the study is conducted in accordance with the Declaration of Helsinki.

Вмешательства

• Препарат panitumumab (EGFR inhibitors)
  Chemotherapy treatment includes anti-EGFR biologics such as cetuximab or panitumumab, antiangiogenic drugs such as bevacizumab or aflibercept. The indication to treat depends from the presence of CTCs analysed for Ras mutation and HER2 expression
