[Colorectal cancer in young patients: presentation, clinicopathological characteristics and outcome].
Previous studies have emphasized the increasing incidence of colorectal cancer (CCR) among young adults and suggest that they may have more aggressive disease and worse five-year survivals than their older counterparts.


OBJECTIVE
Describe the profile of sporadic colorectal cancer in young patients focusing on its prevalence, clinicopathological characteristics, prognostic and survival factors.


METHODS
Three hundred and twenty-five CCR patients were divided in two groups : G1 < 45 years and G2 > 45 years.


RESULTS
13.2% of patients were less than 45 years old. A family history of a first-degree relative with colorectal cancer was more frequent in young patients: 44.1% vs 18.2% (p = 0.025). A significant delay in seeking medical care was noted in G1 patients: 29.7 weeks vs 18.6 weeks (p = 0.01). A trend to have more aggressive stages III and IV at presentation was observed among young patients: 55.8% vs 48.6% (p = 0.8). Mucin-producing tumors were more frequently observed in G1 group: 41.9% vs 12% (p = 0.000). Mean survival was 76.9 months in G1 group and 91.7 months in G2 group (p = NS). Five-year survival was 52% in G1 group and 58% in G2 group (p = 0.6). Stage for stage comparison was not significant in determining survival. The only independent factors were delay in consultation, right location of the tumor, peritoneal carcinomatosis, and the need for chemotherapy.


CONCLUSIONS
This study confirms that colorectal cancer in young patients is frequent. Despite more frequent occurrence of mucin-producing tumors, age is not by itself a worse outcome predictor.
