Enhancing TNM Stage Completeness Using the SEER Summary Stage: A Nationwide Study From Korea.

ABSTRACT:

Objectives

Accurate and complete cancer staging is essential for effective prognosis and treatment planning. This study investigated the feasibility of enhancing the completeness of tumor-node-metastasis (TNM) staging by integrating Surveillance, Epidemiology, and End Results (SEER) Summary Stage data.

Methods

We analyzed data from 5 cancer types (stomach, colorectum, liver, lung, and breast) in Korea (2012-2017). The study assessed the impact of supplementing missing TNM information with SEER Summary Stage data on both staging completeness and 5-year relative survival rates.

Results

The study included 173 061 stomach cancer, 159 199 colorectal cancer, 89 639 liver cancer, 137 103 lung cancer, and 110 286 breast cancer patients. The percentage of missing TNM stage dat
