Why do older women delay presentation with breast cancer symptoms?

Women who delay their presentation with breast cancer for three months or longer are more likely to be diagnosed with later stage disease and have poorer survival. Older women, who are at greater risk of developing breast cancer, are also more likely to delay their presentation. Factors associated with delayed presentation were assessed in 69 women (>65 years) with breast cancer. Previous factors identified for women of all ages were confirmed (having a non-lump symptom p=0.003) or strengthened (non-disclosure of symptom discovery to a relative or close friend p=0.001). Additional factors for delay in this older group included reservations about seeing their GP (p=0.02) and fear of the consequences of cancer (p=0.04). These factors should inform the design of interventions to reduce delays.

Treatment of mammary duct fistula by fistulectomy and saucerization.

This study was designed to assess the efficacy and long-term outcome of fistulectomy and saucerization for treatment of mammary duct fistulae. Mammary fistula is a chronic condition that represents the final step in what has been termed "mammary duct associated inflammatory disease sequence." The treatment is primarily surgical and may include healing by secondary intention or primary closure with or without antibiotics. Reported series are small and often include variable surgical strategies applied without consistency. A consecutive series of 53 patients who had 59 mammary duct fistulae were treated by fistulectomy with saucerization. The median age was 32 years. Wounds were allowed to heal by secondary intention and antibiotics were not used. We reviewed the case records to establish the incidence of recurrent fistula and the time to complete healing. The long-term cosmetic outcome was determined by a postal survey. After a median follow-up of 6 years there had been no relapse in 92%. There was significant delay in healing in six cases (range: 10 to 30 weeks). Thirty-eight patients (83%) gave a definite history of regularly smoking between 10 and 20 cigarettes a day. Two thirds of the patients were either pleased or satisfied with the final cosmetic result of the surgery, but more than 90% said that it left them with some distortion of the nipple. Fistulectomy and saucerization achieves long-term cure in the majority of patients with mammary duct fistula, but it results in some degree of distortion of the nipple. The strong relationship between smoking and the occurrence of mammary duct fistulae is again demonstrated.

Breast reconstruction.

The majority of women who are undergoing mastectomy can also have breast reconstruction. In most breast units, implants and latissimus dorsi flaps can be performed. The more sophisticated transverse rectus abdominis myocutaneous (TRAM) flap-based reconstructions are generally performed by plastic surgeons so that there may be logistic problems in using these techniques for immediate reconstruction. Decisions on technique will also depend on the patient's build and co-existing medical conditions together with the likelihood of need for postoperative radiotherapy as part of the primary local treatment.

Breast duct microendoscopy in nipple discharge: microbrush improves cytology.

BACKGROUND: Breast duct microendoscopy is a new technique that allows direct visualization of the mammary ductal epithelia and has the potential to provide greater accuracy in the diagnosis of benign and malignant breast conditions. We have already established the feasibility of BDME on mastectomy specimens and in patients both under general and local anesthesia. It was the aim of this study to investigate the use of BDME in patients with pathological nipple discharge and to explore the feasibility of using an endoluminal microbrush to take cytology samples from specific lesions. MATERIALS AND METHODS: Breast duct microendoscopy was offered to all patients undergoing surgery for nipple discharge. Surgery included microdochectomy (younger women) and total duct excision (especially in postmenopausal women). The microbrush was used to collect samples whenever an endoluminal papilloma was seen on endoscopy. The results of microbrush cytology samples were compared to ductal lavage samples. RESULTS: Fifty consecutive patients undergoing microdochectomy or total duct excision for nipple discharge had breast microendoscopy (28 general, and 22 under local anesthesia). Thirty-one patients had microdochectomy and nineteen had total duct excision. Visualiza- tion of discharging ducts was accomplished in 100% cases. Endoluminal abnormalities were seen in 33 (66%) patients and dilated ducts were seen in 17 patients. Among the 33 patients, 15 had single papilloma, 3 multiple papilloma and 15 inflammation (erythema, fronds, adhesions). Seven out of eight patients with an intraductal papillorna who had microbrush cytology showed papillary cells whereas only 2 out of 11 patients who had ductal lavage were positive for papillary cells. Thus the sensitivity of the brush cytology technique for the diagnosis of papilloma was 87.5% and the sensitivity of ductal lavage 18% (p = 0.0055). CONCLUSION: Breast duct microendoscopy is an effective way of establishing the etiology of nipple discharge. The microbrush increases the sensitivity of cytology significantly.

Gigantomastia: A problem of local recurrence.

Gigantomastia by definition means bilateral benign progressive breast enlargement to a degree that requires breast reduction surgery to remove more than 1800 g of tissue on each side. It is seen at puberty or during pregnancy. The etiology for this condition is still not clear, but surgery remains the mainstay of treatment. We present a unique case of Gigantomastia, which was neither related to puberty nor pregnancy and has undergone three operations so far for recurrence.

Smoking and prognosis in women with breast cancer.

The hypothesis was that smokers might have more aggressive types of breast cancer because of either delayed diagnosis or higher grade and hence have a worse prognosis. A cohort of breast cancer patients completed a lifestyle questionnaire at the time of diagnosis, including whether they were current smokers, ex-smokers or lifelong non-smokers. Ex-smokers were asked when they had stopped. The participants were 166 women with stage I/II invasive breast cancer diagnosed between October 1984 and March 1987. Participants were divided into three groups: current smokers, ex-smokers and non-smokers. Survival curves were produced by using Cox proportional hazards analysis, with outcome variables for overall and breast cancer-specific survival together with distant relapse-free survival. Smoking was the third most important predictor of distant relapse-free, breast cancer-specific and overall survival after stage and age at diagnosis. These results suggest that smokers are not only more likely to die of other diseases, but also have a higher mortality from breast cancer, compared with those with the disease who have never smoked. The best prognosis, however, was found in those who had given up smoking.

Gigantomastia unrelated to pregnancy or puberty: a case report.

Idiopathic gigantomastia occurs during puberty and pregnancy but a spontaneous case has not been reported in the literature. An unusual case is described, which required urgent bilateral mastectomy to control systemic sepsis and extreme discomfort.

Assessment of breast problems.

Patients with discrete breast lumps, irrespective of age, should be referred for assessment. Premenopausal women with equivocal lumps can be re-checked two weeks later and, if still present or dubious, sent to a breast clinic. Almost all women with breast pain do not need referral unless the symptoms are severe or prolonged. Careful examination will detect those individuals with underlying rib cage pain who can be reassured and given analgesics, if necessary, but not referred. Blood-containing nipple discharge is an indication for referral but such cases can be reassured that, in the absence of a lump, it is unlikely they have breast cancer. Most women who suspect their family history of breast cancer places them at increased risk can be safely reassured and do not need to be kept under surveillance. All those women who are eligible for the NHS screening programme should be encouraged to attend when invited.

Benign breast disease.

Benign breast disorders (BBD), classified by the ANDI system (aberrations of normal development and involution), constitute the major workload in breast clinics. Breast pain (mastalgia) is classified as cyclical, and non-cyclical extramammary causes such as ribircage pain have to be identified. Most patients need reassurance alone but those with moderate/severe pain present for > 6 months may need treatment: randomised trials have shown danazol, bromocriptine and tamoxifen to be effective. Fibroadenoma is the commonest benign solid lump in women aged 15-30 years. The diagnosis must be confirmed by triple assessment. Cysts occur usually in women of middle to late reproductive life. After ultrasound has confirmed the lump as cystic, it can be aspirated. Nipple discharge should be tested for the presence of haemoglobin (Hb). Those with HB+ discharge may require microdochectomy for treatment and diagnosis, common causes being duct papilloma and duct ectasia. Breast abscesses may occur during lactation or in women with duct ectasia and are treated by incision or aspiration together with antibiotics.

Serum alpha L-fucosidase enzyme activity in ovarian and other female genital tract tumors.

OBJECTIVES: To assess the value of serum alpha-L-fucosidase as a tumor marker in the diagnosis of ovarian and other female genital tract tumors. METHODS: One-hundred fifty-one patients were studied; 101 had different genital tract tumors (malignant ovarian tumors (48), carcinoma of the cervix (13), endometrial carcinoma (6), carcinoma of the vulva (6) and benign tumors (28)). A control group of 50 healthy female patients was included. Serum alpha-L-fucosidase activity was determined in all patients and controls. Serum CA 125 level was also determined in patients with malignant ovarian tumors. RESULTS: patients with malignant ovarian tumors showed the lowest level of alpha-L-fucosidase activity in comparison to other malignant and benign tumors of the female genital tract and also in comparison to malignant ovarian tumors. RESULTS: Patients with malignant ovarian tumors showed the lowest level of alpha-L-fucosidase activity in comparison to other malignant and benign tumors of the female genital tract and also in comparison to control group. The majority of ovarian carcinoma patients (90%) had a serum level of < 275 u/ml of alpha-L-fucosidase activity, while more than 90% of the control group and other genital tumors had a serum level of > 275 u/ml. The sensitivity and specificity of serum alpha-L-fucosidase activity in diagnosing epithelial ovarian tumors were 88.5% and 98%, respectively (using a cut-off level of < 275 u/ml). The corresponding figures for CA 125 were 96.2% and 100% (using a cut-off level of > 35 u/ml). CONCLUSIONS: Serum alpha-L-fucosidase enzyme activity can be useful as a tumor marker in diagnosing advanced malignant epithelial ovarian tumors. Its sensitivity and specificity are comparable to CA 125. However, there is a lack of data to support its usefulness in the diagnosis of early stage disease (Stage 1). The cost of doing the test is one-third that of CA 125 and the test can be more widely applied in developing countries.

A controlled trial of adjuvant tamoxifen, with or without prednisolone, in post-menopausal women with operable breast cancer.

A randomised clinical trial has been conducted to compare adjuvant tamoxifen, 20 mg daily, with tamoxifen and prednisolone, 7.5 mg daily, in post-menopausal women with operable breast cancer. There were 254 evaluable patients, of whom 128 were given tamoxifen alone and 126 received tamoxifen and prednisolone. After a median follow-up of 48 months there was no significant difference in relapse-free or overall survival of the two groups. Furthermore, with survival slightly favouring tamoxifen, confidence intervals on the hazard ratio established that a difference in favour of tamoxifen plus prednisolone of even 5% at 5 years was very unlikely (P < 0.02). Thus, despite the relatively small number of patients in this trial, the data clearly establish that prednisolone is not of value as an additional adjuvant agent.

Early drain removal following modified radical mastectomy: a randomized trial.

The dilemma of increasing costs of medical care and shrinking health budgets has stimulated attempts to implement stricter control on expenditure without affecting the quality of care. This study shows that in patients with operable breast cancer, a policy of early discharge after a mastectomy did not have deleterious effects on wound healing and was well accepted by patients. In a randomized trial, drains were removed after either 3 or 6 days postmastectomy, and in both groups of patients there was no difference between the mean volumes of seromas aspirated or the number of aspirations and return visits to the hospital. This suggests that a policy of early discharge is safe, acceptable, economical, and may improve bed utilization.

Fine needle aspiration cytology of palpable breast lesions.

Fine needle aspiration cytology is a safe diagnostic technique for breast cancer and can identify certain benign lesions, which can be excised without affecting surrounding tissue. The combination of experienced operator and cytologist can yield high sensitivity and specificity, together with important prognostic information.

Steroid hormones in lymph and blood from women with early breast cancer.

Postoperative levels of steroid hormones have been measured in lymph and blood of 28 patients undergoing iridium implants as part of conservative treatment for operable breast cancer. The aim was to establish whether there were higher levels of hormones in lymph draining from necrosing tumour cells compared with peripheral blood levels. No differences were found in the ratios of estradiol, dehydroxyepiandrosterone sulphate or sex hormone-binding globulin in those patients with complete compared with incomplete excision of the primary tumour. However, premenopausal patients who had an incompletely excised primary tumour had increased levels of free testosterone in lymph draining from the tumour site on the third and fourth postoperative days. Thus androgens may have an important role in the intracellular metabolism of some breast cancers.
