Overview

Bevacizumab combined with fluorouracil-based chemotherapy is the first-line standard treatment for patients with metastatic colorectal cancer (mCRC). However, some research show that the long-term survival benefit of patients in real world data is inferior to clinical trial. The reason may be related to the difference in follow-up strategy of patients in the real world. Patient-Reported Outcomes (PROs) are a kind of outcome indicators that directly measure and evaluate the disease and its consequences based on how the patient feels about his own health. In advanced cancer, quality of life (QoL) is a major treatment goal. And the electronic patient report outcome (ePRO) has become an effective method to capture the symptoms of patients, which can improve the quality of life and physical and mental health of patients. In order to observe whether ePRO can bring clinical benefits to patients with metastatic colorectal cancer, this study aimed to compare the effects of ePRO and routine follow-up on the quality of life and prognosis of patients with unresectable metastatic colorectal cancer who received first-line bevacizumab combined with chemotherapy. This is an open label, multicenter, randomized controlled prospective study of first-line bevacizumab combined with chemotherapy in patients with unretractable metastatic colorectal cancer.The aim of this study was to assess the impact of ePRO on quality of life and survival outcomes compared with routine follow-up.The study intends to start in February 2021 and end in June 2024.Patients were recruited for 12 months and followed up for 24 months.The study included a screening period (28 days before first-line treatment to 1 day before treatment) and an observation period (from the beginning of treatment to the end of the study).Day 1 (baseline) was defined as the first day of first-line bevacizumab combined with chemotherapy.About 338 patients will be enrolled in the study in China, and enrolled patients will be randomly assigned to one of the following two groups in a 1:1 ratio.
