RESUMO
INTRODUCTION: Treatment of women with oestrogen-receptor positive breast cancer who are high risk for general anaesthetic remains controversial. Current guidance is based on studies pre-dating aromatase inhibitors (AIs) which may have also included hormone-receptor negative patients. Such studies have demonstrated improved disease-free survival and local disease control following surgery when compared with primary hormone therapy (PHT) alone. However uncertainty persists regarding benefit of surgery over optimal hormone treatment in patients with significant co-morbidity. METHOD: Retrospective cohort study comparing efficacy of PHT in oestrogen-receptor positive breast cancer patients considered unsuitable for surgery. Co-morbidity was scored retrospectively using the Charlson Index. Overall survival and disease specific survival were noted and multivariate analysis performed to identify predictors of treatment failure. RESULTS: 106 patients treated for breast cancer at Southampton University Hospital with PHT without surgery were identified (Mean age 84.1 years, range 48-101). 94.3% had a probability of 10 year survival of 2.25% or less according to the age-weighted Charlson score. Kaplan-Meier analysis demonstrated a four-year survival of 30% and breast cancer specific survival of 60%. Cox proportional hazards model demonstrated high-grade disease (grade III vs. grade I/II: HR = 2.007; 95% Confidence Interval (CI) = 1.004-4.014. P = 0.049) and ultrasound axillary staging (indeterminate/definite lymphatic involvement vs. no involvement: HR = 1.944; 95% CI = 1.010-3.742. P = 0.047) independently predicted early failure of PHT. CONCLUSION: A high proportion of elderly and comorbid patients die with breast cancer rather than from breast cancer. Elderly comorbid patients who initially respond to primary hormone therapy have a less than 30% incidence of delayed treatment failure during their life time; however patients with grade III disease or an abnormal axillary ultrasound are twice as likely to fail first choice PHT.

Sclerosing lymphocytic lobulitis (SLL) and amyloidosis of the breast are both rare. We report the case of a 59 year old woman who presented with suspicious microcalcifications on routine screening mammography. Wire-guided excision biopsy showed features typical of SLL but also localised amyloid deposits within the specimen. Amyloidosis and SLL may have similar immunological causes. This patient represents the first documented association of these two disorders.

AIMS: To investigate the role of needle core biopsy (NCB) in the preoperative assessment of impalpable breast lesions, mainly derived from the NHS Breast Screening Programme (NHSBSP) and to assess our own modifications to a suggested system for the classification of breast NCBs. METHODS: The NCB, fine needle aspiration cytology (FNAC), and radiology scores from 298 women with non-palpable breast lesions presenting between January 1997 and December 1998, together with the open biopsy results (where available) were collated and analysed. RESULTS: The mean follow up period was 15.8 months (range, 5-28). The 298 NCB specimens were categorised as follows: unsatisfactory/non-representative (B1; n = 61; 20.5%), benign but uncertain whether representative (B2r; n = 52; 17.4%), benign (B2; n = 103; 34.6%), lesions possibly associated with malignancy but essentially benign (B3a; n = 9; 3.0%), atypical epithelial proliferations (B3b; n = 10; 3.4%), suspicious of malignancy (B4; n = 7; 2.3%), and malignant (B5; n = 56; 18.7%). Excision biopsy was performed in 43 cases within the B1 (n = 19), B2r (n = 8), B2 (n = 8), and the B3a (n = 8; data unavailable in one case) categories, revealing malignancy in 18 (42.8%) cases and in 65 cases within the B3b, B4, and B5 categories, revealing malignancy in 64 cases (98.5%). The sensitivity of NCB for malignancy was 87.7%, with a specificity and positive predictive value of 99.3% and 98.5%, respectively. FNAC had an inadequacy rate of 58.7%, a complete sensitivity of 34.5% and a specificity of 47.6%. CONCLUSIONS: This study confirms the value of NCB in the preoperative assessment of impalpable breast lesions. Two new categories are suggested for the NCB classification; category B2r for benign breast tissue where representativeness is uncertain, and the subdivision of category B3 into B3a for benign lesions potentially associated with malignancy (for example, radial scars and intraduct papillomas) and B3b for more worrisome atypical epithelial proliferations. These will aid the accurate audit of NCB and identify more clearly the intellectual pathway leading to a particular assessment.

AIMS: Mastectomy and axillary clearance are standard operations for the treatment of breast carcinoma. Drainage of the mastectomy site and axilla is often required to allow accumulating blood and inflammatory fluids to escape. However, there is a lack of data relating to how long suction drains should stay in situ after major breast surgery. In our study we have tried to address this deficit by comparing the efficacy of 5-day post-operative drainage with 8-day post-operative drainage. METHODS: Patients requiring mastectomy and axillary clearance were randomized to having drains removed on day 5 or day 8 post-operatively. The number of lymphoceles, aspirations and total aspiration volumes in chest and axillary drains were compared. RESULTS: From a total of 121 patients enrolled into the study, 64 patients were randomized to the 5-day group and 57 to the 8-day group. There were significant differences regarding the number of aspirations and total aspiration volumes in chest and axillary drains between the two groups, favouring 8-day drainage. However the number of lymphoceles drained in the 5-day group was significantly higher than the 8-day group. CONCLUSIONS: Five-day post-operative drainage is as safe as 8-day post-operative drainage in the management of patients undergoing major breast surgery, but results in an increase in lymphocele aspiration and aspiration volume.

Presence or absence of lymph node metastases is the most accurate prognostic indicator in breast cancer. Clinical examination is unreliable in detecting involved nodes. Preoperative ultrasound scan of the axilla has been performed in 140 consecutive women with breast cancer. The sensitivity for involved nodes was 66% which was significantly higher than clinical examination (42%) (P = less than 0.01). However ultrasound gave more false positives than clinical examination and thus no overall improvement in prognostic information was achieved.

INTRODUCTION: In vivo labelling of human breast tumours with bromodeoxyuridine (BrdUrd) and analysis by flow cytometry (FCM) allows the labelling index (LI), S phase duration (t(s)) and the potential doubling time (t(pot)) of the tumour to be estimated. METHODS: The data for a series of tumour specimens from 75 patients with invasive breast carcinoma were reported in 1991, correlated with their lymph-node status, tumour size and grade. RESULTS AND CONCLUSIONS: This study reports the follow-up data over 10 years in respect of time to recurrence and death from the disease. There were no significant correlations between proliferation data and outcome measures. No adverse events were identified which could be attributed to the use of the halogenated pyrimidine label in vivo.

AIMS: To assess the changes in blood haemoglobin concentration and serum iron indices as a consequence of breast operations for cancer in our unit. METHODS: Haematological parameters were measured in 109 patients undergoing definitive operative treatment for breast carcinoma. RESULTS: A mean fall in haemoglobin of 2.1 g (P=0.001) occurred in patients undergoing mastectomy and axillary clearance and of 1.3 g (P<0.001) in patients undergoing wide local excision and axillary clearance. The transferrin saturation (serum iron/total iron binding capacity) in both sets of patients after surgery fell on average to levels that would be expected to impair subsequent red cell production. CONCLUSION: The changes in iron indices that occurred were unrelated to the degree of blood loss consistent with a possible inflammatory effect of the operation. Oral iron therapy is unlikely to be of benefit to operative breast patients if they have normal pre-operative iron stores.

Antibiotic prophylaxis has been used to good effect in the prevention of post-operative wound infections in patients undergoing gastrointestinal operations. We have assessed the use of a single dose of intravenous antibiotic (Augmentin 1.2 g), given with induction of anaesthesia as prophylaxis, against post-operative wound infection in women undergoing clean, elective breast surgery. Three hundred and thirty-four patients were recruited. Of the 164 receiving antibiotic prophylaxis 29 (17.7%) had wound infections compared with 32 (18.8%) in the placebo group (P=0.79). There were no significant differences in any other post-operative infective complications. Antibiotic prophylaxis is probably not required in clean, elective breast surgery.

Many patients diagnosed with breast cancer will develop metastases and these have diverse presentations. We have reviewed 100 consecutive patients who have died with metastatic breast cancer, to determine the frequency, sites and mode of presentation of recurrent disease. The commonest site of failure was loco-regional (n = 61), this usually presented with a mass, but a minority of patients also complained of pain. Bone metastases developed in 60 patients and produced bone pain, pathological fracture (n = 6) or cord compression (n = 5). Pulmonary metastases producing shortness of breath were diagnosed in 34 patients and were asymptomatic in a further 10. Intra-abdominal metastases were found at some time in 23 patients, most commonly in the liver (n = 20) and the majority complained of epigastric pain (n = 17). Brain metastases occurred in 23 patients and produced a wide range of symptoms including those of a space-occupying lesion (n = 10), cranial nerve palsy (n = 7), diabetes insipidus (n = 3), focal limb weakness (n = 2) and meningitis (n = 1). Three patients had choroid metastases producing reduced visual acuity. Recurrent breast carcinoma can present in a variety of ways, therefore any new symptom or sign should be considered to represent recurrence until proved otherwise.

A prospective study of the axillary nodal status of women found to have an invasive breast cancer within the prevalence screening round is reported. Thirty-one per cent of patients were lymph node positive. Twenty-two per cent of patients with an impalpable tumour and 41% of those with a palpable tumour had involved axillary lymph nodes. Only 6% of patients with a tumour of less than 10 mm had diseased axillary nodes. Of the factors examined only the size of the invasive component of the primary tumour was related to the axillary lymph node status. This proportion of patients with positive lymph nodes is higher than might be expected and is likely to represent those patients with potentially symptomatic breast tumours detected by breast screening in the first round.

Thirty patients with early breast cancer have been studied prospectively to assess whether being offered a choice of surgery (simple mastectomy or wide excision plus radiotherapy) influences levels of anxiety and depression pre- and post-operatively. A significantly higher percentage of the patients not offered a choice of surgery experienced clinical levels of anxiety and depression pre-operatively and up to 2 months post-operatively compared with patients offered a choice; the results were also similar for the husbands of these patients. At 6 months, differences between the 2 groups were not statistically significant, although the trend remained the same with more patients not offered a choice of treatment showing high levels of anxiety and depression. Patients offered a choice of surgery had similar pre-operative levels of anxiety and depression to patients with benign breast disease and patients undergoing surgery for non-cancerous conditions. This study indicates that with proper counselling patients and husbands suffer less stress if they are allowed to take an active part in the treatment of their cancer.

The effects of carbohydrate, lipid, and nitrogen metabolism of recently available lipid emulsions containing either 50% medium-chain triglyceride (MCT) and 50% long-chain triglyceride (LCT) or 100% LCT were compared in elective surgical patients. Postoperative urinary urea excretion was similar during isocaloric MCT/LCT and LCT infusions (1.9 mg/kg/min) and was decreased compared with a standard infusion of 5% glucose (1 mg/kg/min). Plasma glucose and insulin concentrations were similar during both lipid and low dose glucose infusions. However, plasma triglyceride and nonesterified fatty acid concentrations were decreased during the MCT/LCT infusion compared with the LCT infusion, suggesting that the MCT/LCT emulsion was cleared from the circulation faster than pure LCT. Ketone body concentrations were similar during all three infusions. MCT/LCT emulsion can be safely infused perioperatively and has similar nitrogen conserving properties to LCT in these circumstances.

Stereotactic core biopsy (SCB) is performed on mammographically suspicious, non-palpable lesions of the breast. Reported sensitivities of SCB for the detection of ductal carcinoma in situ (DCIS) vary from 41% to 93%. We have developed a simple mathematical model to predict the probability of retrieving at least one diagnostic core from a focus of DCIS. We make recommendations of the number of samples needed for different sized areas of microcalcification. The sensitivity of SCB is affected by needle placement accuracy, diameter of the area of microcalcification (d), histological density of DCIS (x) (calculated as 7.5% by previous studies) and number of core samples (n) removed. The probability of achieving at least one representative core sufficient for diagnosis (P(core)) is defined as: P(core) = 1-(1 + p ([1- (x/100)]d - 1 ))n, where rho is the probability of a SCB accurately targeting the area of microcalcification. At least seven core samples should be removed in small foci (<5 mm) of DCIS to achieve a 0.75 probability of an accurate diagnosis. The probability of a diagnostic biopsy of larger areas of DCIS (>10 mm) is 0.95 when five cores are removed. This formula serves as an explanation to patients why SCB may fail to diagnose DCIS, and justifies the retrieval of more core samples to increase the probability of an accurate diagnosis and to reduce the chance of a non-representative core. In the absence of sufficient samples, a wire-guided open biopsy is necessary to exclude DCIS.

The size of the skin ellipse for a mastectomy varies between patients and the accurate marking and tailoring of the skin flaps is often learnt by the surgical trainee only with increasing experience. Within the Breast Unit, a mathematical model was calculated to predict the required width of the skin ellipse for a successful mastectomy. Measurements of the straight-line distance from mid-clavicular point to the infra-mammary fold and maximum vertical height of the nipple above the infra-mammary fold were taken with the patient relaxed and supine. A close correlation (r = 0.85) was noted. Further analysis demonstrated a linear relationship between the pre-operative height to which the nipple could be suspended above the infra-mammary fold and the required maximum skin ellipse width (r = 0.87, P < 0.001). This linear relationship is easy to remember and is a useful check to ensure that the skin flaps intended will be just right. This same technique may be applicable to skin ellipses elsewhere.

Fifty-one consecutive women with early breast cancer underwent wide excision and axillary clearance. After wide excision five biopsies were taken from the walls of the cavity. On histological examination tumour was present in the cavity biopsies in 13 cases (25%). The presence of ductal carcinoma in situ in the primary tumour was not associated with an increased number of positive cavity biopsies. In nine cases incomplete excision was due to separate foci of invasive or in situ carcinoma, in two cases tumour was contiguous with the primary carcinoma and in two, separate foci and contiguous disease both occurred. The high incidence of residual local tumour after wide excision of breast cancer demands the need for postoperative irradiation to the breast and frequent review.

The advent of mammographic breast screening has increased the detection of ductal carcinoma in situ (DCIS), which now accounts for 15-20% of all breast cancer. While symptomatic DCIS has been treated satisfactorily by mastectomy, this may be an overtreatment of smaller screen-detected lesions. Although local excision, with or without radiotherapy, is associated with a significant risk of local recurrence of DCIS or invasive cancer, salvage surgery is usually successful. The long-term breast-specific mortality rate of treatment by mastectomy and local excision are similar. Whereas mastectomy is still appropriate for women with lesions > 30 mm in diameter or centrally placed and for those women who demand the best possible disease-free survival, local surgery should otherwise be considered.
