Abstract

Insights

The PREICO project demonstrates that comprehensive genomic profiling (CGP) is feasible in public healthcare, identifying actionable biomarkers in most advanced cancer patients. This approach supports precision oncology by informing treatment decisions and clinical trial access.

Area of Science:

  • Oncology
  • Genomics
  • Precision Medicine

Background:

  • Next-generation sequencing (NGS) is crucial for precision oncology but faces economic and logistical hurdles in public healthcare.
  • The PREICO project aimed to broaden access to comprehensive genomic profiling (CGP) beyond standard indications within a cancer center network.
  • Launched in 2022 by the Catalan Institute of Oncology (ICO), PREICO sought to overcome these barriers.

Purpose of the Study:

  • To assess the feasibility and impact of implementing a centralized CGP prescreening program in a public healthcare setting.
  • To identify actionable genomic alterations in patients with advanced solid tumors, particularly those without public NGS access.
  • To evaluate the role of CGP in informing clinical decision-making and facilitating access to targeted therapies and clinical trials.

Main Methods:

  • Analysis of patients with advanced solid tumors enrolled between February 2022 and March 2024.
  • Comprehensive genomic profiling (CGP) performed on 249 patients.
  • Molecular results reviewed by a Molecular Tumor Board (MTB) to generate structured reports for clinical guidance.

Main Results:

  • CGP identified at least one pathogenic alteration in 96.3% of evaluable samples.
  • Actionable biomarkers, including high tumor mutational burden (TMB-H) and microsatellite instability (MSI), were detected.
  • 25 patients received NGS-matched therapies (10.3% of cohort), with a 20% objective response rate and 40% clinical benefit rate.

Conclusions:

  • The PREICO project indicates that a centralized CGP prescreening program is feasible within public healthcare systems.
  • CGP successfully identified actionable alterations in a significant proportion of patients, guiding treatment and clinical trial enrollment.
  • This initiative expands access to precision oncology tools for a wider patient population.
