title: [Prognostic significance of clinical and pathomorphological factors in colorectal cancer: a uni- and multivariate analysis].
abstract: The aim of this study was to estimate the prognostic value of clinical and pathomorphological factors in cancer of the colon and rectum. We studied seventy-seven patients subjected to a radical surgery with a five-year follow-up. Survival was calculated using the Kaplan-Meier method and compared by log-rank test. Multivariate analysis was performed using Cox's regression model. Overall 5-year survival was 68%. Primary tumour spread beyond the bowel wall and regional lymph node involvement appeared to be independent prognostic factors, significantly influencing the survival of patients. Other variables including patient's age and sex, tumour location, symptom duration before treatment onset, grade of differentiation and mucinous histology had no significant impact on prognosis. Tumour spread beyond the bowel wall and metastases to regional lymph nodes are the most useful prognostic factors in patients with colorectal carcinoma. In routine practice the clinical stage of cancer should remain a reference against which other clinical and pathomorphological variables are assessed.
