The value of metastatic screening in early primary breast cancer.

Abstract

Up to 25 per cent of patients presenting with "early" breast cancer subsequently develop distant metastases indicating that this group must have occult disseminated disease when initially evaluated. Routine pre-operative haematological and radiological investigation is recommended in order to identify these patients and alter their management accordingly. The aim of this study was to examine the outcome of a pre-operative metastatic screening programme in patients presenting with early breast cancer. Eighty-two patients underwent surgery for stage I-II breast cancer over a 5 yr period from 1990-1995. Before surgery all patients underwent screening tests for metastatic disease. These included a full blood count, liver function tests, chest x-ray, skeletal survey and abdominal ultrasound. Of the 82 patients, metastatic screening significantly altered management in only 1 patient who was found to have asymptomatic lymphangitis carcinomatosa on chest x-ray. The results of this study suggest that the number of patients restaged by screening for metastatic breast cancer may be small and questions the necessity for its routine use in the management of early primary breast cancer.
