Colon cancer in blacks: age-related presentation and survival within a similar socioeconomic group.

Young blacks with colon cancer continue to have a poor survival rate for reasons that remain undetermined. Medical records of blacks with colon cancer diagnosed at an inner-city hospital during a 10-year period were reviewed. The cohort consisted of 118 indigent, nonmigratory patients grouped by age. Group 1 consisted of 11 patients under age 50, and group 2 consisted of 107 patients age 50 and over. Admission symptoms were significantly different between groups. Patients in group 1 presented with abdominal pain more often than patients in group 2, and none of the patients in group 1 had anemia or obstruction, which comprised 14% and 11%, respectively, of the presenting symptoms in group 2 patients. Overall, survival difference was significant; the survival rate was 22.8 months for group 1 and 64.2 months for group 2 (P < .02). There was no difference in stage at presentation to account for the decreased survival in group 1. It is possible that the overwhelming majority (45%) of patients in group 1 with abdominal pain actually had more virulent disease, which accounts for the short survival. These individuals must be targeted for more aggressive patient education, surveillance, early detection and treatment, and follow-up.
