Survival of Early and Late Operated Patients with Colorectal Cancer

摘要

Many factors influencing survival were analyzed and delay in diagnosis is one of the most important. Eighty patients with PH diagnosis of colorectal cancer (CRC) were included in the study. They were divided into two matched groups: early operated patients (symptoms were presented for 3 months) and late operated patients (complications were presented in time of diagnosis). Follow-up period was 5 year. Five years survive 70% in group of early operated patients and 7,5% in group of late operated patients. Difference in survival in these two groups is highly statistically important (x2=32,16, p<0,001). Average of survival in early operated patients was 54,8 months and 17,3 months in late operated patients (log Rank=42,26, p<0,001). Delay in diagnosis is highly significant factor of survival patients with CRC. Local recurrence, distant metastasis or death are 4 time more frequent in patient with longer delay in diagnosis.
