Summary
A colorectal cancer register identified prognostic factors. TNM staging was the only independent predictor of survival, highlighting its importance in large bowel cancer prognosis.
Area of Science:
- Oncology
- Gastroenterology
- Biostatistics
Background:
- Colorectal cancer prognosis is influenced by various factors.
- Accurate prognostic indicators are crucial for patient management and treatment planning.
Purpose of the Study:
- To evaluate the prognostic relevance of morphologic and clinical variables in colorectal cancer.
- To identify independent predictors of survival using univariate and multivariate analyses.
Main Methods:
- Establishment of a colorectal cancer register in Northern Italy.
- Univariate and multivariate (Cox model) analyses of 134 patients diagnosed in 1984, with a 5-year follow-up.
- Evaluation of clinical (TNM staging, age) and morphologic (growth pattern, fibrosis) variables.
Main Results:
- Overall 5-year survival was 37% (43% for cancer-related deaths).
- Univariate analysis identified TNM staging, age, growth pattern, and fibrosis as significant.
- Multivariate analysis revealed TNM staging as the sole independent prognostic factor.
Conclusions:
- TNM staging is a critical independent predictor of survival in colorectal cancer.
- Further investigation of clinical and morphologic variables within specific TNM or Dukes' classes is warranted.
