| Popis: | Correlation of p53 expression with 5-year survival and histopathological parameters was examined immunohisto-chemically in two groups of 30 patients with oesophageal carcinoma (5-year survivors versus non-survivors). Tumour type, sex, operative procedure and age were matched. Some 64 per cent of squamous carcinomas and 79 per cent of adenocarcinomas were p53 positive. Normal squamous, normal glandular and metaplastic glandular epithelia were negative. Dysplastic squamous and glandular epithelium adjacent to tumours was positive when the tumour was positive and negative when it was not. Univariate analysis showed that nodal status (P = 0·001), and grade and depth of invasion (both P = 0·01) correlated with outcome. Correlation of tumour grade with outcome, when the most poorly differentiated area is used, is a novel finding for oesophageal carcinoma. The p53 status was not significantly associated with survival or any of these parameters. |
