CGA Guided Ultrafractionated RT and First-line Systemic Treatment in Elderly or Frail Patients with MCRC

Официальное название

Comprehensive Geriatric Assessment (CGA) Guided Ultrafractionated Radiotherapy and First-line Systemic Treatment in Elderly or Frail Patients with Metastatic Colorectal Cancer

Обзор

This is a prospective, multicentre, cohort study. For cohort 1(CGA cohort), experimental cohort, older or Frail patients with metastatic colorectal cancer will receive Ultrafractionated Radiotherapy (RT) and Comprehensive Geriatric Assessment (CGA) Guided systemic treatment. All patients will receive Ultrafractionated RT and PD-1 antibody. Furthermore, CGA will assess all patients and classify them into Frail, Vulnerabe, or Fit. Frail patients will receive Best Supportive Care (BSC); Vulnerabe patients will receive single agent chemotherapy, with/without targeted therapy, and BSC; Fit patients will receive doublet chemotherapy, with/without targeted therapy, and BSC. For cohort 2 (external control cohort), external control from real word, data of patients with the same baseline characteristics from the same period and the same institute will be prospectively collected. The primary endpoint is Progression Free Survival (PFS). The secondary endpoints include the grade 3-4 acute adverse effects (AE) rate, quality of life (QoL), the Overall Response Rate (ORR), 1-year Disease-specific survival (DSS) rate, 1-year overall survival (OS) rate etc.
