Kylie Minogue's breast cancer: effects on referrals to a rapid access breast clinic in the UK.

We examine the effect of the announcement of Kylie's breast cancer on referrals to a rapid access breast clinic in the United Kingdom. General practitioner referrals were examined, concentrating on June 2005; the month following Kylie's diagnosis. Time series analysis with autoregressive integrated moving average modeling was used to forecast data. There was a significant increase in referrals and radiographic investigations, with no increase in the number of malignant diagnoses. It is encouraging that media campaigns appear to make women more 'breast aware;' however there may also be a detrimental effect with increased radiation exposure, anxiety and cancer phobia.

Antibiotic prescription for patients referred to a specialist breast clinic.

Hospital referral is indicated as an emergency for breast infections not settling with oral antibiotics. Referrals to a breast clinic over a period of 6 months were assessed for prior antibiotic prescription. A total of 1078 patients were seen during this period. 91 (8%) patients had been prescribed antibiotics, 71% of which had been prescribed for non-infective conditions. Of those patients treated for infection, 42% had the wrong antibiotic prescribed. The final diagnoses for patients inappropriately prescribed antibiotics were chest wall pain in 23% and duct ectasia in 14%. Although the reasons for prescription of antibiotics are mutifactorial, careful examination of the patient will diagnose chest wall pain. Delayed prescribing may be appropriate for some patients.

Tamoxifen and pregnancy.

Women are conventionally advised to stop tamoxifen before attempting pregnancy. The risks of congenital malformations or late teratogenic manifestations in adulthood are unknown. Following an informed discussion about the uncertainties of tamoxifen exposure on pregnancy women should be offered the choice whether to continue or stop tamoxifen before attempting pregnancy. An unexpected pregnancy in a women taking tamoxifen could continue if the pregnant woman accepts the possibility of a teratogenic effect that tamoxifen could have on the fetus.

Final diagnoses following C3 (atypical, probably benign) breast cytology.

Fine needle aspiration cytology is part of the triple assessment of breast lesions. The final diagnoses are reported in patients with breast lesions that produce C3 or atypical, probably benign cytology. C3 cytology was obtained from 61 breast lesions between January 1998 and December 1999. Ten (16%) of these lesions were malignant, only three of which were clinically or radiologically suspicious or malignant. Three were diagnosed by core biopsy, but three required excision biopsy after a benign core, and four diagnosed by excision without core. For benign lesions; in five the core was considered diagnostic, three were excised to confirm benignity, 11 monitored and 32 excised without core. Core biopsy should be performed in preference to cytology in the assessment of breast lesions. Where C3 cytology is obtained, core biopsy should be performed, but excision biopsy may still be required. The definition of C3 cytology should be changed to indeterminate.

Replace fine needle aspiration cytology with automated core biopsy in the triple assessment of breast cancer.

All patients presenting with a symptomatic breast lump are assessed by means of triple assessment (clinical examination, radiology in the form of mammography and cytology by means of a fine needle aspiration) performed by the clinician in the rapid access breast clinic at the Royal Gwent Hospital, Newport, UK. In our initial experience, it was found that a significant number of patients were returning to clinic for the results of the triple assessment to find that the cytology was not conclusive and hence needed a core biopsy, thus delaying diagnosis and definitive treatment. Therefore, a prospective study was carried out over a 6-month period, where all patients presenting with a symptomatic lump with a clinical or radiological suspicion of breast cancer had, in addition to the standard triple assessment, an automated core biopsy, thus giving rise to the quadruple assessment of the breast lump. A total of 52 patients with a clinical or radiological suspicion of breast cancer were included over this 6-month period. Of these 52 patients, 31 had a definitive diagnosis of breast cancer on fine needle aspiration (sensitivity 60%) compared with 50 of the 52 patients on core biopsy (sensitivity 96%). When radiology was diagnostic of breast cancer (R 5), the sensitivity of cytology was 61% compared with 97% with core biopsy. However, when radiology was not diagnostic of cancer (R 1-4), the sensitivity of cytology fell to 53% while the sensitivity of core biopsy remained high at 95%. The overall cellularity rate for cytology was 96%, which exceeds the BASO requirement for fine needle aspiration cytology. From these results, we conclude that automated core biopsy has a superior diagnostic power when compared with fine needle aspiration cytology and hence should replace fine needle aspiration cytology in the assessment of symptomatic breast lumps.

The long-term course of mastalgia.

Mastalgia is a common condition in women of reproductive years. We have assessed the long-term course in patients with severe mastalgia by distributing a postal questionnaire to 212 patients previously studied in 1983 who had attended the mastalgia clinic at the University Hospital of Wales, Cardiff. 175 patients (83%) responded, with an original diagnosis of cyclical mastalgia (CM) in 120 and non-cyclical mastalgia (NCM) in 55. The median age of onset of breast pain was 36 years (range 12-63 years). The average duration of pain was long (median 12 years), especially if it started in the second or third decade of life. Pain persisted in 68 (57%) of CM and 35 (64%) of NCM patients. In CM patients resolution was commonly associated with a 'hormonal' event, notably the menopause; in NCM patients it more often seemed to be spontaneous. Severe mastalgia ran a chronic relapsing course often requiring repeated drug treatments.

The effect of danazol on discrete benign breast lumps.

Surgical biopsy of benign breast lumps produces a significant surgical workload, morbidity and cost. A double-blind placebo-controlled trial of danazol 200 mg daily was carried out with the aim of reducing the size of solid discrete breast lumps, thereby avoiding surgical biopsy in benign cases. Twenty-two women with lumps diagnosed as benign by clinical examination, mammography and cytology were randomized to take danazol and 26 placebo. The patients were assessed monthly by two clinicians until surgical biopsy. Twenty patients in each treatment group were evaluated and five patients discontinued treatment (two on danazol, three on placebo) and three (all on placebo) were found to be malignant. There was no difference in the number of lumps which responded to treatment with danazol or placebo. There was a reduction in the number of lumps which subsequently developed in the breasts treated with danazol during the 12-month follow-up period, but this failed to achieve statistical significance. Danazol does not promote resolution of solid discrete benign breast lumps. Careful selection of women over 25 years for surgery with solid discrete breast lumps is required, utilizing a dedicated breast cytologist with a multidisciplinary approach, to avoid missing breast cancers.

Drug therapy of mastalgia. What are the options?

Severe breast pain or mastalgia is a common symptom, affecting up to 70% of the female population at some time in their lives. It accounts for approximately 50% of referrals to a specialised breast clinic, two-thirds of patients having cyclical and one-third experiencing noncyclical mastalgia, or pain arising from the chest wall deep to the breast. After exclusion of breast cancer and proper reassurance, 85% of patients can be discharged from the clinic without specific treatment. In only 15% of patients is the pain severe enough to affect their lifestyle and warrant drug therapy. Using EF-12 (gammalinolenic acid; gamolenic acid) as first-line therapy, with danazol and bromocriptine usually as second-line agents, a clinically useful improvement in pain can be anticipated in 92% of patients with cyclical and 64% with noncyclical mastalgia. Patients with severe recurrent or refractory mastalgia may require treatment with tamoxifen, goserelin or testosterone, but the short and long term adverse effects of these drugs preclude their use as first-line agents. Chest wall pain is usually self-limiting, but symptomatic relief can often be obtained using steroidal and local anaesthetic injections or nonsteroidal anti-inflammatory drugs.

Plasma fatty acid profiles in benign breast disorders.

Breast pain (mastalgia) and macroscopic breast cysts present commonly. Mastalgia may be improved by dietary manipulation to reduce saturated fat or supplement essential fatty acid intake. Fatty acid profiles were measured in women with mastalgia and breast cysts, before and during treatment with evening primrose oil, a rich source of essential fatty acids. The fatty acid profiles of both groups of patients were abnormal, with increased proportions of saturated fatty acids and reduced proportions of essential fatty acids. Treatment with evening primrose oil improved the fatty acid profiles towards normal, but this was not necessarily associated with a clinical response.

A case control study of factors associated with macroscopic breast cysts.

Women who have a breast cyst aspirated are at increased risk of developing breast cancer. We present an age-matched case control study comparing the reproductive characteristics of 352 women who had a breast cyst aspirated with a control group of 352 contemporaneous clinically normal women. Women with breast cysts were more likely to be nulliparous [odds ratio (OR) = 2.28, 95% confidence interval (CI) = 1.34-3.88] or have a late age at first live birth (chi 2 trend = 5.6, P less than 0.025), and a late menopause (chi 2 trend = 4.3, P less than 0.05). They were less likely to have ever used the oral contraceptive pill (OR = 0.38, 95% CI = 0.26-0.55) or to have used the pill for a short duration (chi 2 trend = 16.8, P less than 0.001), and were less likely to have had a hysterectomy (OR = 0.58, 95% CI = 0.36-0.93). They were more likely to wear a small bra (chi 2 trend = 18.6, P less than 0.001) and bra cup (chi 2 trend = 5.6, P less than 0.025). Nulliparity, late age at first live birth and late menopause are factors common to breast cancer risk.

Drug treatments for mastalgia: 17 years experience in the Cardiff Mastalgia Clinic.

Mastalgia commonly presents to medical practitioners. The majority of patients can be managed by exclusion of cancer and reassurance. In some the severity of pain affects the quality of life and drug treatment should be considered. Since its inception 324 patients with cyclical mastalgia and 90 with non-cyclical mastalgia have received a therapeutic trial of drug treatment in the Cardiff Mastalgia Clinic. Overall 92% of those with cyclical mastalgia and 64% with non-cyclical mastalgia obtained a clinically useful response to therapy. Danazol was the most effective drug, with bromocriptine and evening primrose oil having equivalent efficacy. Many fewer adverse events were complained of by patients treated with evening primrose oil than danazol or bromocriptine.

Reproductive factors associated with mastalgia.

Mastalgia has been classified as an aberration of the normal, rather than a disease. We present an age-matched, case-control study which compares the reproductive factors of patients with severe cyclical and noncyclical mastalgia with control groups of women who presented to a breast clinic but in whom no clinical abnormality was found and who did not later develop breast disease. There were few statistically significant differences in reproductive factors between the cases and controls, which lends some support to the concept that mastalgia can be considered to be an aberration of the normal.
