Comprehensive Quality Management (CQM) in the PLCO Trial

Area of Science:

• Oncology
• Clinical Trials
• Quality Management

Background:

• The National Cancer Institute (NCI) integrated comprehensive quality control and assurance (CQA) into the design of the Prostate, Lung, Colorectal, and Ovarian (PLCO) Cancer Screening Trial.
• The PLCO trial spanned over two decades, involving multiple institutions and complex protocols, necessitating robust quality management.

Purpose of the Study:

• To describe the implementation and operationalization of CQA within the PLCO Cancer Screening Trial.
• To highlight the role of CQA in ensuring the scientific and clinical credibility of trial data.

Main Methods:

• Implementation of a comprehensive and adaptable quality assurance and control program across all trial aspects.
• Integration of CQA principles into trial management, governance, and operations.
• Application of practices analogous to Total Quality Management (TQM).

Main Results:

• CQA was successfully embedded throughout the PLCO trial's design and execution.
• The CQA program facilitated coordination across multiple institutions and committees.
• The CQA framework supported the integration of diverse and complex protocols over 20 years.

Conclusions:

• The PLCO trial's CQA program ensured the integrity and credibility of its extensive data.
• The CQA implementation in PLCO serves as a model for large-scale, long-term clinical trials.
• The study demonstrates the successful operationalization of CQA principles in a major cancer screening trial.
