title: The results of surgical treatment for carcinoma of the rectum of St Mark's Hospital from 1948 to 1972.
abstract: The surgical treatment of 3163 patients seen at St Mark's Hospital with a single adenocarcinoma of the rectum in the years 1948-72 is described and the results analysed. In 2948 patients (93-2 per cent) the primary tumour was removed. The operative mortality fell from 7-0 per cent in the years 1948-52 to 2-1 per cent in 1968-72. The proportion of restorative operations has risen steadily over the years to a level of 41-1 per cent in the years 1968-72. There were 2410 operation survivors in the years 1948-67. The crude 5-year survival rate in the whole group was 47-1 per cent (corrected figure 56-7 per cent), and 56-6 per cent (corrected figure 68-4 per cent) for the 1931 survivors of radical operations. Comparison of results for patients surviving radical synchronous combined excision and radical anterior resection shows a significant difference in the two groups: in the former the crude 5-year survival rate was 52-7 per cent (corrected figure 63-8 per cent), and in the latter group the respective figures were 66-7 and 79-4 per cent. A higher proportion of Dukes' A and B cases and of low grade tumours are shown as the pathological background to the more favourable prognosis for patients surviving radical anterior resection.
