Perceived sensitivity of mammographic screening: women's views on test accuracy and financial compensation for missed cancers.

OBJECTIVES: To estimate women's expectations of the accuracy of screening mammography and to explore attitudes towards compensation for missed cancers. DESIGN: Cross sectional survey (by telephone). SETTING: Australia; population-based survey conducted in April 1996. PARTICIPANTS: Random sample of women aged 30-69 years. A total of 2935 women completed the Breast Health Survey (adjusted response rate 65%). A random sample of 115 completed this sub-survey on perceived sensitivity of mammographic screening and compensation for missed cancers. RESULTS: About one third of women (32.2%, 95% CI 23.7, 40.7) had an unrealistically high expectation of the sensitivity of screening mammography, reporting it to be 95% or higher. Approximately 40% of the women (43.5%, 95% CI 34.4, 52.6) thought that screening mammography should pick up all cancers (should have a sensitivity of 100%). Just under half the women (45.2%, 95% CI 36.1, 54.3) said financial compensation should be awarded for a cancer missed by screening mammography even if the cancer was missed as a consequence of the small failure rate of the test. Younger women living in metropolitan areas and women who had realistic expectations of the accuracy of the tests were more likely to favour financial compensation. CONCLUSION: Unrealistically high expectations of the sensitivity of screening mammography were common in this group of women. Many women favoured financial compensation for missed cancers even if the cancer was missed solely because of the failure rate of the test. Public education is required to inform women of the limited sensitivity of breast cancer tests but this may not reduce claims for financial compensation when cancers are missed.

The application of the 99Tcm phosphate bone scan to the study of breast cancer.

Comparison of the gamma camera bone scan and radiological survey in 190 patients with breast cancer has confirmed the superiority of the bone scan in the positive diagnosis of skeletal metastases. In 47 patients with known (X-ray positive) bony metastases the scan was positive in all but 2, and in 24 (50 per cent) the scan showed more lesions than the X-ray had indicated. In 60 patients with a clinical suspicion of bone metastases but negative X-rays, the scan was positive in 29 (48 per cent). Eighty-three patients with primary breast cancer were studied at the time of initial presentation. All had a normal radiographic skeletal survey but 24 (27 per cent) had scan evidence of occult metastases. It is concluded that a bone scan is indicated in all patients with breast cancer where skeletal metastases are suspected. Repeated bone scans may introduce new therapeutic possibilities, by providing an earlier objective index of progression of metastatic disease and also by providing a quantitative method of assessing the response to therapy.
