Colorectal carcinoma in the black population of South Africa is very uncommon when compared with incidence among whites. Even in whites the proportion of patients with colorectal carcinoma under 25 years of age is less than 1% (Hardin, 1972). Eight cases of colorectal carcinoma in black patients under 25 years of age are presented. None had any evidence of premalignant lesions of the colon. The prognosis of colorectal carcinoma in young adults is poor in most series and this group of patients was no exception. Reasons for this poor prognosis are mentioned. A more aggressive approach to the early detection and treatment of the lesion in young patients is essential.
与白人相比，南非黑人人群中的结直肠癌非常少见。即使在白人中，25岁以下结直肠癌患者的比例也不到1%（哈丁，1972年）。本文报告了8例25岁以下黑人结直肠癌患者。无一例有结肠癌前病变的证据。在大多数系列研究中，年轻成人结直肠癌的预后较差，本组患者也不例外。文中提到了预后差的原因。对年轻患者的病变进行更积极的早期检测和治疗至关重要。
