Cancer of the colon and rectum in Ghana: a 5-year prospective study.
A prospective study of 134 patients who presented to a teaching hospital in Ghana for the first time with colorectal cancer between January 1987 and December 1991 is reported. The mean number of new patients per year was nearly three times that of a decade ago. The disease afflicts both sexes equally and the age of highest incidence is in the seventh and eighth decades. Some 65 patients had colonic cancer and 69 rectal lesions. Most patients presented with advanced disease and only four of 109 in whom disease was staged (3.7 per cent) had Dukes A tumours. Right-sided cancer of the colon was more common than that of the left. The importance of rectal examination is emphasized by the finding that 78 per cent of rectal tumours were within reach of the examining finger. 'Curative' resection was possible in 60 per cent of patients with colonic cancer but in only 36 per cent of those with rectal tumours. The postoperative mortality rate of patients who underwent laparotomy was 13.6 per cent and in those who had resection 5.5 per cent. Long-term follow-up was poor. These results emphasize the need for accurate data collection on colorectal carcinoma, public education on the importance of early diagnosis and follow-up after treatment. These findings also call for a study of the epidemiology and aetiology of colorectal cancer in Ghana.
