Mutations of the p53 tumour suppressor gene have been found in most human cancers, including ovarian epithelial malignancies. This study investigated whether the presence or absence of p53 mutation was associated with outcome following platinum-based chemotherapy in patients with ovarian cancer. DNA samples from tumour tissue and blood were obtained from 73 patients with primary tumours, 50 of whom received platinum-based adjuvant chemotherapy. Single-strand conformation polymorphism analysis and direct DNA sequencing of exons 5-8 detected mutations in 44% (32 of 73) of tumours. These were more common in late-stage (III or IV) than in early-stage disease (I or II) (p=0.03). There was no association with histological type, volume of residual disease following surgery, or initial CA125 levels. No significant association was found between p53 status and overall survival or disease-free survival following chemotherapy. Likewise, there was no correlation between p53 mutation and response to chemotherapy as defined by normalization of CA125 levels. Tumours with p53 missense mutations recurred within a significantly shorter time than those with normal p53 (p=0.04). In addition, there was a tendency for tumours with missense mutations to have a shorter disease-free survival than those with non-missense mutations, although this did not reach statistical significance (p=0.07).
