Colorectal Cancer Patient Data with Preoperative ACR Biomarker and Survival Outcomes, 2017

A 2017 retrospective study of 966 colorectal cancer patients from Shanxi Province Cancer Hospital who underwent radical surgery. The dataset includes clinicopathological characteristics and survival outcomes used to develop and validate a prognostic nomogram based on the preoperative albumin-to-carcinoembryonic antigen ratio (ACR). It was created by Yanchun Shi and last updated in April 2026.

Use Cases

• Developing prognostic models for overall survival based on the ACR biomarker and clinicopathological features.
• Validating the predictive performance of a nomogram against traditional TNM staging using concordance indices.
• Analyzing the association between low ACR levels and adverse clinicopathological characteristics in colorectal cancer.
• Training models for disease-free survival prediction using identified independent protective factors.

Strengths

• Includes data from 966 patients, providing a substantial sample for analysis.
• The developed nomogram demonstrated predictive performance with C-index values of 0.786 for OS and 0.772 for DFS.
• Multivariate analysis identified high ACR as an independent protective factor with specific hazard ratios (e.g., HR=0.433 for OS).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count for the underlying data tables is unknown, which may limit suitability assessment.
• Data is from a single hospital in 2017 and may reflect geographic and temporal bias.
