Breast screening: the psychological sequelae of false-positive recall in women with and without a family history of breast cancer.

The psychological effects of false-positive mammography were evaluated in 124 women who had taken part in the U.K. National Health Service Breast Screening Programme. In addition, the effects of recall on women with and without a family history were compared. These women were asked to complete the Hospital Anxiety and Depression Scale (HADS) before being invited to attend for screening, at recall and 5 weeks and 4 months after recall. At screening and at recall, the women were asked to complete the Health Questionnaire (HQ) which measures stress-related behaviour changes in the previous week. In the week before screening, compared with women who did not have a family history of breast cancer, women with a family history had lower scores on HADS depression and reported fewer stress-related behaviour changes. At recall, regardless of family history, the women were more likely to have borderline or clinically significant anxiety than at baseline or screening. Nevertheless, for most women, recall-induced anxiety was relatively transient (less than 5 weeks). Compared with women without a family history, women with a family history were more anxious 4 months after recall, although their anxiety scores tended to be lower (P < 0.06) than at baseline. A strength of the present study is that the initial baseline measure was uncontaminated by the screening process. Women who did not complete questionnaires at one or more of the subsequent time points scored higher on HADS depression at baseline, indicating that the results are likely to have underestimated the effects of recall. Screening appears to be less stressful for women with a family history than for those without a history. However, for both groups recall causes short term distress. Breast screening programmes should ensure that steps are taken to minimise the number of women who are recalled for unnecessary investigations.

Does the insertion of more than one wire allow successful excision of large clusters of malignant calcification?

AIM: To determine whether the insertion of more than one localization wire for larger areas of malignant microcalcification reduces the need for re-excision. METHOD: This is a retrospective study of 101 cases of malignant calcifications preoperatively marked by one or more wires. Surgical and histopathology data were obtained from hospital records. Mammograms and specimen radiographs were evaluated without knowledge of the eventual outcome, i.e., whether further surgery was required or not. All cases had a preoperative diagnosis of malignancy. RESULT: In this study the group of patients in which two or more wires were inserted had mammographically larger lesions (p<0.000001) but did not have a greater chance of needing re-excision (p=0.822). Mammograms that demonstrated flecks of microcalcification outlying the main cluster were also more likely to require further surgery (p<0.01). Calcifications associated with high-grade ductal carcinoma in situ (DCIS) had three times the risk of requiring further surgery (p<0.01). However, as reported in other studies re-excision was not related to breast size (p=0.63) [Kollias J, Gill PG, Beamond B, Rossi H, Langlois S, Vernon-Roberts E. Clinical and radiological predictors of complete excision in breast-conserving surgery for primary breast cancer. Aust N Z J Surg 1998;68:702-6]. CONCLUSION: It was previously suggested that the risk of re-excision for DCIS is related to the size of the initial lesion [Cheng L, Al-Kaisi NK, Gordon NH, Liu AY, Gebrail F, Shenk RR. Relationship between the size and margins of ductal carcinoma in situ of the breast and residual disease. J Nat Cancer Inst 1997;89:1356-60]. However, in the present study larger clusters of microcalcification that have been 'bracketed' by two or more wires do not appear to have a greater requirement for re-excision. Grading of the malignant microcalcifications preoperatively may encourage the surgeon to take a wider margin. Careful examination of the mammograms at localization to include outlying flecks could help to reduce the need for further surgery.
