Pilot studies on the p53 gene in nipple aspirate fluid from patients with breast cancer.
Nipple Aspirate Fluid (NAF) from patients with breast cancer is a potential source of exfoliated tumour material amenable to molecular biological study, but few such data have been reported. In this study we demonstrate that polymerase chain reaction (PCR) amplification of p53 gene DNA is achievable in a proportion of NAF samples from breast cancer patients. Subsequently four NAF samples from patients whose primary tumours were identified as having a defined p53 mutation were studied by single stranded conformational polymorphism analysis (SSCP). Two samples yielded PCR product indistinguishable from wild type and two yielded no product. Whilst no cancer-related genetic mutations were demonstrated in NAF samples, further study is warranted.
