Background: The molecular genetic analysis of invasive breast cancer has identified breast cancer as a genetically complex disease. Ductal carcinoma in situ (DCIS) is thought to represent a preinvasive step in breast cancer progression, yet we know little about its biologic behavior or the genetic alterations present. Because of the increasing diagnosis of DCIS by mammography screening and the debate over how DCIS should be managed, there is a clear need to define the molecular events underlying the development of DCIS.Purpose: Our purpose was to identify patterns of genetic alterations in DCIS.Methods: A group of 30 formalin-fixed, paraffin-embedded blocks of tissue collected from 1987 through 1989 from 21 patients with DCIS was studied. Chromosomal imbalances were determined by interphase cytogenetic analysis using the fluorescence in situ hybridization (FISH) technique. DNA probes were used that recognize chromosome-specific repetitive sequence loci at the centromeres of chromosomes 1, 3, 4, 6, 7, 8, 9, 10, 11, 16, 17, and 18. FISH was also used to detect ERBB2 gene amplification in DCIS. To complement the FISH studies, microsatellite analysis of markers near the BRCA1 region of chromosome 17 was done on tissue microdissected from multiple areas of DCIS. Chromosomal imbalances were determined by comparisons of chromosomal indices (total number of hybridization spots per total number of nuclei counted) of normal and DCIS tissue, using the two-sided Mann-Whitney test.Results: Using FISH, we have identified patterns of DNA loss and gain of certain chromosome-specific centromeric markers in DCIS. We observed frequent gains of markers on chromosomes 3, 10, and 17 as well as loss of chromosome 18-specific centromeric sequences. ERBB2 gene amplification was detected in tumors from four of 15 patients studied and was clearly limited to the tumor cells within the ducts. Because of the availability of topologically distinct regions of tumors from individuals, we were able to show that paired tumor specimens from individuals share genetic alterations and also have unique ones, suggesting clonal diversity within tumors. The combination of FISH and microsatellite analyses suggested that alterations in chromosome 17 may be quite complex; three of five patients whose samples were analyzed had allelic imbalance at markers on the long arm of chromosome 17.Conclusions: FISH and microsatellite analyses are useful in detecting extensive genetic alterations in DCIS. Examinations of DCIS tissue using these techniques have identified chromosomes 1, 3, 10, 16, 17, and 18 as candidate sites worthy of immediate study.Implications: This approach may give direction to future research aimed at precisely mapping loci altered in DCIS and help in understanding the biologic events associated with tumor progression or recurrence.

Background: To determine whether, when primary breast cancer is treated by local excision supported by systemic therapy appropriate to the oestrogen receptor status (ER) of the tumour, local radiotherapy can be avoided.Methods: We carried out a randomised controlled trial in 585 patients aged less than 70 years with primary breast cancers of 4 cm or less in size in four specialist units and seven other hospitals in Scotland. After local excision of the tumour (1 cm margin) and an axillary lymph-node clearance or sample, all patients received systemic therapy with oral tamoxifen 20 mg daily or six 3-weekly intravenous bolus injections of cyclophosphamide 600 mg, methotrexate 50 mg, and fluorouracil 600 mg per m2, depending upon the ER concentration in the primary tumour. Patients were then randomly allocated to postoperative radical radiotherapy (50 Gy to breast with boost to the tumour bed) or to no further local treatment. The median follow-up of living patients was 5.7 years. The primary analysis was by intention to treat but since some patients did not receive systemic therapy appropriate to their ER status, a subsidiary analysis was restricted to 464 patients in whom all details of the protocol had been observed.Findings: In the primary analysis survival was equal in the radiotherapy and non-radiotherapy groups (hazard ratio [HR] 0.98, 95% CI 0.67-1.44). Event-free survival showed an advantage in the irradiated patients (HR 0.54, 95% CI 0.39-0.74), largely due to fewer loco-regional relapses (HR 0.20, 95% CI 0.12-0.33). The relapse rate in the ipsilateral breast was 24.5% in the non-irradiated group and 5.8% following breast irradiation. The subsidiary analysis confirmed these findings and indicated the advantage of radiotherapy irrespective of ER concentration. There was a non-significant trend towards fewer distant metastases in the irradiated group.Interpretation: After local excision of a primary breast cancer, we conclude that radiotherapy to the residual breast tissue is advisable even when selective adjuvant systemic therapy is given.

A 62-year-old man was admitted to the medical admissions ward with right thigh pain presumed to be a deep vein thrombosis (DVT). Subsequent duplex ultrasonography excluded a DVT but noted the presence of a significant amount of subcutaneous gas. A plain film radiograph was performed with the same finding raising the possibility of necrotising fasciitis (NF). Only at this point was digital rectal examination performed revealing a large rectal mass oozing pus and blood. CT imaging showed thickening of the rectum consistent with a tumour with gas and fluid in the perirectal space extending to the anterolateral right femur. Despite aggressive debridement and treatment, the patient deteriorated and died 6 weeks later. This case should serve as a reminder to consider digital rectal examination and the occurrence of a rectal perforation in all patients who present with suspicious thigh swellings., (2015 BMJ Publishing Group Ltd.)

Digital infrared thermal imaging (DITI) using a thermal camera has potential to be a useful tool for the production animal industry. Thermography has been used in both humans and a wide range of animal species to measure body temperature as a method to detect injury or inflammation. The objective of these experiments was to compare the temperature of the eye (EYE) or muzzle (MUZ) measured using DITI to vaginal (VT) and rectal temperature (RT) as measures of core body temperature in hair sheep and beef cattle. In Exp.1 EYE, VT and RT were measured in lactating, multiparous hair sheep ewes (St. Croix White, n = 10, and Dorper × St. Croix White, n = 10) in a non-febrile state 5 times over a 48-h period. Data loggers were used to measure VT and a digital veterinary thermometer was used to measure RT. There was a high correlation (P < 0.001) between VT and RT (r = 0.95), EYE and RT (r = 0.76) and EYE and VT (r = 0.77). In Exp. 2 EYE, MUZ, VT and RT were measured in multiparous, lactating ewes (St. Croix White, n = 2, and Barbados Blackbelly, n = 12) at -12, -1, 0, 1, 2, 3, 4, 6, 12, 24, 36, and 48 h after being administered lipopolysaccharide (LPS; n = 7; 0.2 µg/kg BW, i.v.) or saline (n = 7; 0.5 mL, i.v.). Data loggers were used to measure VT and a digital veterinary thermometer was used to measure RT. When data were combined across treatments (LPS and saline) there was a high correlation (P < 0.001) between VT and RT (r = 0.96), EYE and RT (r = 0.82), MUZ and RT (r = 0.72), and EYE and VT (r = 0.93). In Exp. 3 EYE, MUZ, VT and RT were measured in multiparous, non-lactating, pregnant Senepol cattle (n = 44) between 0900 and 1200 h on a single day. A digital veterinary thermometer was used to measure both VT and RT. There was a high correlation (P < 0.001) between VT and RT (r = 0.78), a moderate correlation (P < 0.001) between VT and EYE (r = 0.52), RT and EYE (r = 0.58) and EYE and MUZ (r = 0.48). There was no correlation (P > 0.10) between RT or VT and MUZ. The findings of these three studies indicate that temperature of the eye, measured using DITI, can be used as an indicator of core body temperature in hair sheep and beef cattle as an alternative to using vaginal or rectal temperature.

An 80-year-old man with papillary thyroid carcinoma of the neck underwent surgery and radioiodide therapy. He presented 11 years later with a lesion adjudged from fine needle aspiration to be a squamous cell carcinoma (SCC). Histological analysis of the excised mass revealed a lymph node overwhelmed with papillary thyroid carcinoma and moderately differentiated SCC thought to have transformed from papillary cells. A very small number of similar transformations specifically involving the 'tall cell variant' of papillary carcinoma transforming to spindle cell carcinoma have been reported previously. This case report demonstrates clear images of this rare occurrence and briefly considers factors leading to de-differentiation. The clinician should consider possible transformation from papillary thyroid cancer in cases of SCC of the head and neck as this variation may be more aggressive.

Background: The oncological safety of skin-sparing mastectomy (SSM) followed by immediate breast reconstruction (IBR) is debated owing to a presumed compromise in the completeness of mastectomy. Current evidence is poor as it is based mostly on short-term follow-up data from highly selected patients., Methods: A prospectively maintained institutional database was searched to identify patients who underwent SSM and IBR between 1995 and 2000. A retrospective review of medical records was carried out, including only patients with ductal carcinoma in situ and invasive breast cancer. During this time all patients treated with mastectomy were offered IBR regardless of tumour stage., Results: Follow-up data from 253 consecutive patients with IBR were reviewed. Patients with incomplete follow-up data and those undergoing SSM for recurrent disease following previous lumpectomy were disregarded, leaving 207 for analysis. Offering IBR to all women requiring mastectomy resulted in a large proportion of patients with advanced disease. During a median follow-up of 119 months, 17 (8·2 per cent) locoregional, six (2·9 per cent) local and 22 (10·6 per cent) distant recurrences were detected; the overall recurrence rate was 39 (18·8 per cent). Overall recurrence rate was associated with axillary lymph node metastasis (P = 0·009), higher stage (P < 0·001) and higher tumour grade (P = 0·031). The breast cancer-specific survival rate was 90·8 per cent (19 of 207 women died from recurrence)., Conclusion: Based on these long-term follow-up data, SSM combined with IBR is an oncologically safe treatment option regardless of tumour stage., (Copyright © 2012 British Journal of Surgery Society Ltd.

Objectives: To describe the effect of multidisciplinary care on survival in women treated for breast cancer., Design: Retrospective, comparative, non-randomised, interventional cohort study., Setting: NHS hospitals, health boards in the west of Scotland, UK., Participants: 14,358 patients diagnosed with symptomatic invasive breast cancer between 1990 and 2000, residing in health board areas in the west of Scotland. 13,722 (95.6%) patients were eligible (excluding 16 diagnoses of inflammatory cancers and 620 diagnoses of breast cancer at death)., Intervention: In 1995, multidisciplinary team working was introduced in hospitals throughout one health board area (Greater Glasgow; intervention area), but not in other health board areas in the west of Scotland (non-intervention area)., Main Outcome Measures: Breast cancer specific mortality and all cause mortality., Results: Before the introduction of multidisciplinary care (analysed time period January 1990 to September 1995), breast cancer mortality was 11% higher in the intervention area than in the non-intervention area (hazard ratio adjusted for year of incidence, age at diagnosis, and deprivation, 1.11; 95% confidence interval 1.00 to 1.20). After multidisciplinary care was introduced (time period October 1995 to December 2000), breast cancer mortality was 18% lower in the intervention area than in the non-intervention area (0.82, 0.74 to 0.91). All cause mortality did not differ significantly between populations in the earlier period, but was 11% lower in the intervention area than in the non-interventional area in the later period (0.89, 0.82 to 0.97). Interrupted time series analyses showed a significant improvement in breast cancer survival in the intervention area in 1996, compared with the expected survival in the same year had the pre-intervention trend continued (P=0.004). This improvement was maintained after the intervention was introduced., Conclusion: Introduction of multidisciplinary care was associated with improved survival and reduced variation in survival among hospitals. Further analysis of clinical audit data for multidisciplinary care could identify which aspects of care are most associated with survival benefits.

The breast cancer risk of women already under family history surveillance was accurately assessed according to national guidelines in an attempt to rationalize the service. Women attending two breast units in Glasgow between November 2003 and February 2005 were included. One thousand and five women under annual surveillance were assessed and had their relatives diagnoses verified. Four hundred and ninety-seven women were at significantly increased risk and eligible for follow-up. Five hundred and eight (50%) women attending were not eligible for family history surveillance, and 498 (98%) of these women accepted discharge. In conclusion, national guidelines have helped to more clearly define women who should undergo surveillance. This avoids unnecessary and potentially harmful routine investigations, and the service has been improved.

We demonstrate that intravenous delivery of human, or rat, pancreas-derived pathfinder (PDP) cells can totally regenerate critically damaged adult tissue and restore normal function across a species barrier. We have used a mouse model of streptozotocin (STZ)-induced diabetes to demonstrate this. Normoglycemia was restored and maintained for up to 89 days following the induction of diabetes and subsequent intravenous delivery of PDP cells. Normal pancreatic histology also appeared to be restored, and treated diabetic animals gained body weight. Regenerated tissue was primarily of host origin, with few rat or human cells detectable by fluorescent in situ hybridization (FISH). Crucially, the insulin produced by these animals was overwhelmingly murine in origin and was both types I and II, indicative of a process of developmental recapitulation. These results demonstrate the feasibility of using intravenous administration of adult cells to regenerate damaged tissue. Critically, they enhance our understanding of the mechanisms relating to such repair and suggest a means for novel therapeutic intervention in loss of tissue and organ function with age.

Background: Initial results of the UK/ANZ DCIS (UK, Australia, and New Zealand ductal carcinoma in situ) trial suggested that radiotherapy reduced new breast events of ipsilateral invasive and ductal carcinoma in situ (DCIS) compared with no radiotherapy, but no significant effects were noted with tamoxifen. Here, we report long-term results of this trial., Methods: Women with completely locally excised DCIS were recruited into a randomised 2×2 factorial trial of radiotherapy, tamoxifen, or both. Randomisation was independently done for each of the two treatments (radiotherapy and tamoxifen), stratified by screening assessment centre, and blocked in groups of four. The recommended dose for radiation was 50 Gy in 25 fractions over 5 weeks (2 Gy per day on weekdays), and tamoxifen was prescribed at a dose of 20 mg daily for 5 years. Elective decision to withhold or provide one of the treatments was permitted. The endpoints of primary interest were invasive ipsilateral new breast events for the radiotherapy comparison and any new breast event, including contralateral disease and DCIS, for tamoxifen. Analysis of each of the two treatment comparisons was restricted to patients who were randomly assigned to that treatment. Analyses were by intention to treat. All trial drugs have been completed and this study is in long-term follow-up. This study is registered, number ISRCTN99513870., Findings: Between May, 1990, and August, 1998, 1701 women were randomly assigned to radiotherapy and tamoxifen, radiotherapy alone, tamoxifen alone, or to no adjuvant treatment. Seven patients had protocol violations and thus 1694 patients were available for analysis. After a median follow-up of 12·7 years (IQR 10·9-14·7), 376 (163 invasive [122 ipsilateral vs 39 contralateral], 197 DCIS [174 ipsilateral vs 17 contralateral], and 16 of unknown invasiveness or laterality) breast cancers were diagnosed. Radiotherapy reduced the incidence of all new breast events (hazard ratio [HR] 0·41, 95% CI 0·30-0·56; p<0·0001), reducing the incidence of ipsilateral invasive disease (0·32, 0·19-0·56; p<0·0001) as well as ipsilateral DCIS (0·38, 0·22-0·63; p<0·0001), but having no effect on contralateral breast cancer (0·84, 0·45-1·58; p=0·6). Tamoxifen reduced the incidence of all new breast events (HR 0·71, 95% CI 0·58-0·88; p=0·002), reducing recurrent ipsilateral DCIS (0·70, 0·51-0·86; p=0·03) and contralateral tumours (0·44, 0·25-0·77; p=0·005), but having no effect on ipsilateral invasive disease (0·95, 0·66-1·38; p=0·8). No data on adverse events except cause of death were collected for this trial., Interpretation: This updated analysis confirms the long-term beneficial effect of radiotherapy and reports a benefit for tamoxifen in reducing local and contralateral new breast events for women with DCIS treated by complete local excision., Funding: Cancer Research UK and the Australian National Health and Medical Research Council., (Copyright © 2011 Elsevier Ltd.

Background: There is no consensus agreement regarding optimal management of locally excised ductal carcinoma in situ (DCIS) or features of greatest assistance in predicting disease behaviour. Cases in the UKCCCR/ANZ DCIS trial have been histologically reviewed to determine the features of prognostic importance., Method: A total of 72% of 1694 cases entered into the UKCCCR/ANZ DCIS trial had full pathological review. A large number of histological features were assessed, blinded to outcome and compared regarding ability to predict ipsilateral recurrence, as either DCIS or progression to invasive carcinoma., Results: Pathological features associated with ipsilateral recurrence in univariate analysis included high cytonuclear grade, larger lesion size, growth pattern, presence of necrosis or chronic inflammation, incompleteness (or uncertainty of completeness) of excision and smaller margin width. Receipt of post-operative radiotherapy was also a strong prognostic factor.We report a novel sub-division of the large group of high-grade lesions, which enables identification of a very poor prognosis sub-group; namely, DCIS that is of high cytonuclear grade, predominantly (>50%) solid architecture, bearing extensive comedo-type necrosis (>50% of ducts). In addition, we found little difference in ipsilateral recurrence rates between low- and intermediate-grade groups. Hazard ratios for low, intermediate, high and the new, very high, grade were 0.42, 0.33, 0.62 and 1.00, respectively, for ipsilateral in situ or invasive recurrence., Conclusion: We present a novel pathological classification for DCIS with substantially better prognostic discrimination for ipsilateral recurrence than the classical categorisation based on cytonuclear grade alone.

We have isolated a novel progenitor cell population from adult rat pancreatic ducts, termed pancreatic-derived progenitor cells (PDPCs). Here, we report the in vitro culture, selection, and characterization of Thy1.1-positive and Thy1.1-negative PDPC subpopulations. These cells exhibit bipotentiality for differentiation into both pancreatic and hepatic cell types. Significantly, they express Pdx-1. Using a serum-free FGF-4-containing differentiation protocol, we have observed a time course of both morphological and gene expression changes indicative of hepatic lineage differentiation for the Thy1.1-positive subpopulation. These cells express albumin and store glycogen, typical features of mature hepatocytes. The Thy1.1-positive subpopulation could also readily be induced to differentiate into a pancreatic lineage with characteristic morphological changes resulting in three-dimensional islet-like structures and the transcriptional expression of insulin and glucagon in addition to Pdx-1. No morphological evidence of islet-like clusters was observed using the Thy1.1-negative population. However, Thy1.1-negative cells grown in pancreatic differentiation medium did show insulin gene transcription. Glucagon was not expressed in the undifferentiated Thy1.1-negative cells, nor was it induced in vitro after differentiation. The detection of Pdx-1 transcriptional expression in both populations indicates their potential as a novel source of non-beta-cell-derived insulin.

The future challenge of breast surgery, the so-called oncoplastic approach is reviewed in this article. The authors discuss the most frequently applied surgical techniques as well as their indications. Medline and pubmed search was carried out using the following keywords and cross-references: "oncoplastic breast surgery", "breast reconstruction", "breast conserving surgery" and "reduction mammoplasty". Original and review papers published in English language and their references were included. In the literature surprisingly, a large variety of breast oncoplastic surgical procedures has been described. Although reconstructions with local flaps are relatively easy procedures, proper indications for these are critical in order to improve cosmesis after breast conservation. Applications of pedicled flaps are technically more demanding, and only properly trained oncoplastic breast or plastic surgeons are able to provide the possibly best aesthetic outcome after mastectomy or breast conserving surgery. Finally, carrying out free flap reconstructions after mastectomy should be assigned exclusively to plastic surgeons qualified in microsurgical techniques, and not to surgical oncologists. As conclusions oncoplastic approach will be an integral element of the surgical treatment of breast cancer in the future. Breast oncoplastic training is an interdisciplinary task, which combines surgical oncological management of breast cancers with aesthetic/reconstructive breast surgery.

Background: Traditional survival curves cannot easily be used to predict outcome for an individual patient on a year-to-year basis. This difficulty is partly overcome by yearly mortality analysis. This method was employed to analyse long-term follow-up of three cancers: colorectal, ovarian and breast cancer., Methods: The study used prospectively collected cancer registry data from geographically defined regions in Scotland. Cohort sizes were 7196 patients with breast cancer, 3200 with colorectal cancer and 1866 with ovarian cancer. Follow-up extended to 23 years., Results: Two distinct patterns of mortality emerged. Mortality rates for ovarian and colorectal cancer were initially high (41 and 21 per cent) but decreased rapidly; by 10 years patients had either died or were cured. The influence of stage diminished with follow-up. Breast cancer mortality was lower than that of colorectal or ovarian cancer, but remained raised in comparison to the general population throughout follow-up. The influence of breast cancer size reduced with follow-up, whereas that of nodal status persisted., Conclusion: Patients with breast cancer live at increased risk of death to the end of follow-up, supporting the concept of dormancy in breast cancer biology. This was not observed with colorectal or ovarian cancer., (Copyright (c) 2007 British Journal of Surgery Society Ltd.)

Background: Efficient histological quantification of tumour-infiltrating T and B lymphocyte (TIL) subsets in archival tissues would greatly facilitate investigations of the role of TIL in human cancer biology. We sought to develop such a method., Methods: Ten x40 digital images of 4 micro sections of 16 ductal invasive breast carcinomas immunostained for CD3, CD4, CD8, and CD20 were acquired (a total of 640 images). The number of pixels in each image matching a partition of Lab colour space corresponding to immunostained cells were counted using the 'Color range' and 'Histogram' tools in Adobe Photoshop 7. These pixel counts were converted to cell counts per mm(2) using a calibration factor derived from one, two, three or all 10 images of each case/antibody combination., Results: Variations in the number of labelled pixels per immunostained cell made individual calibration for each case/antibody combination necessary. Calibration based on two fields containing the most labelled pixels gave a cell count minimally higher (+5.3%) than the count based on 10-field calibration, with 95% confidence limits -14.7 to +25.3%. As TIL density could vary up to 100-fold between cases, this accuracy and precision are acceptable., Conclusion: The methodology described offers sufficient accuracy, precision and efficiency to quantify the density of TIL sub-populations in breast cancer using commonly available software, and could be adapted to batch processing of image files.

Sirtuins are genes implicated in cellular and organismal ageing. Consequently, they are speculated to be involved in diseases of ageing including cancer. Various cancers with widely differing prognosis have been shown to have differing and characteristic expression of these genes; however, the relationship between sirtuin expression and cancer progression is unclear. In order to correlate cancer progression and sirtuin expression, we have assessed sirtuin expression as a function of primary cell ageing and compared sirtuin expression in normal, 'nonmalignant' breast biopsies to breast cancer biopsies using real-time polymerase chain reaction (PCR). Levels of SIRT7 expression were significantly increased in breast cancer (P<0.0001). Increased levels of SIRT3 and SIRT7 transcription were also associated with node-positive breast cancer (P<0.05 and P<0.0001, respectively). This study has demonstrated differential sirtuin expression between nonmalignant and malignant breast tissue, with consequent diagnostic and therapeutic implications.

We have employed a biological chemistry approach to dissect the mechanisms underpinning cellular responses to oxidant stress and to develop biologically relevant anti-oxidants. We have used telomere biology to define cellular stress responses and have observed telomere independent, p21- and p16-dependent stasis following oxidative insult in human fibroblasts. This was accompanied by a [corrected] reduction in XRCC5 expression and a reduction in [corrected] SIRT 1 expression. Using these markers in conjunction with senescence-associated beta-galactosidase expression, we have developed and screened novel nitrone based anti-oxidant compounds. We have identified functional compounds that are unsuitable for use in primary human cells. This has allowed subsequent identification of suitably structured compounds that act as superior biological anti-oxidants, which have potential for use in clinical interventions.

Background: Early trials that compared breast and axillary treatments showed differing recurrence rates without significant differences in survival. Consequently, there was a wide range of opinion and practice in the management of breast cancer. The present study explored this variability in surgical management to determine the impact of breast and axillary treatment on recurrence and survival., Methods: The records of 2776 women with histologically confirmed invasive breast cancer diagnosed between 1986 and 1991 were reviewed. The relationship between adequacy of breast and axillary treatment, recurrence and survival was examined in 2122 women who had surgery with curative intent. A Cox proportional hazards model that included tumour size, node status, grade, socioeconomic status and use of adjuvant therapy was used., Results: Inadequate treatment was associated with a significantly higher risk of local recurrence after breast-conserving surgery (relative hazard ratio (RHR) 4.19 (95 per cent confidence interval (c.i.) 2.73 to 6.43); P < 0.001). Inadequate axillary treatment was associated with a significantly higher risk of regional recurrence (RHR 2.29 (95 per cent c.i. 1.65 to 3.16); P < 0.001). The risk of death from breast cancer was significantly higher if locoregional treatment was inadequate (RHR 1.29 (95 per cent c.i. 1.07 to 1.55); P = 0.008)., Conclusion: Adequate surgery is fundamental to the optimal treatment of breast cancer. Inadequate surgery resulted in higher recurrence rates despite adjuvant treatments.

Objective: The primary objective was to conduct a detailed analysis of individual variation in psychological morbidity in the year following surgery for breast cancer. The salience of the patients' "illness perceptions" to morbidity was examined as a secondary objective., Methods: Psychological morbidity was assessed with the General Health Questionnaire (GHQ-28) in a prospective study of 371 women having surgery for primary breast cancer. Patients also completed the Illness Perception Questionnaire (IPQ), Mental Adjustment to Cancer Scale (MAC) and the Eysenck Personality Scales (EPS). Assessments were made postoperatively and at 3, 6 and 12 months after surgery., Results: Whilst descriptive statistics indicated a general reduction in mean distress over the 12-month follow-up, close analysis showed that a quarter of all patients maintained clinically significant levels of distress throughout the period. Patients with chronically elevated distress were characterised by higher levels of neuroticism, greater symptom awareness, more pain and poorer self-rated general health. In the regression analysis, psychological morbidity across the 1-year follow-up was predicted principally by the immediate postoperative state of distress, IPQ symptom awareness and the perceived time line of the illness, general health and, to a more minor extent, by neuroticism., Conclusion: There is marked individual variation in psychological morbidity in the year following breast cancer surgery, which is reliably predicted by the patient's immediate postoperative state of distress, her perception of the impact of the symptoms and the time line of the disease. Subgroups of patients with chronically high distress are characterised by factors including personality and negative perceptions and beliefs about their illness.

Aim: To determine whether axillary recurrence reflects inadequate axillary treatment or adverse pathological features., Methods: The case-records were reviewed of 2122 women aged under 75 years, treated for invasive breast cancer during the time-period 1/1/86-31/12/91 in a geographically defined area. Data were abstracted on operations performed, pathological features, post-operative treatments and details of axillary recurrence. The risk of axillary recurrence was examined by pathological, treatment and patient factors., Results: Axillary recurrence was more than twice as likely after inadequate compared to adequate treatment of the axilla (adequate staging or axillary radiotherapy or clearance). Delayed treatment of the axilla was not as successful as adequate primary treatment: multiple axillary recurrences were twice as common, one third of which were uncontrolled at time of death. Inadequate surgical treatment was associated with increased rates of recurrence despite endocrine therapy, chemotherapy or radiotherapy. Lymphoedema was twice as common if axillary radiotherapy was combined with any axillary surgical procedure., Conclusions: Axillary recurrence is more common in tumours with adverse pathology but may also result from inadequate axillary treatment. In order to minimise axillary recurrence, optimal treatment of the axilla entails adequate staging (sampling of four or more nodes) and treatment (axillary clearance or radiotherapy and endocrine therapy) in all women.

We evaluated whether social deprivation affected decision-making for breast cancer surgery. Of 3419 patients, 53.6% had mastectomy and this was predicted by deprivation, age, tumour size and hospital, all of which retained significance on multivariate analysis, except deprivation. Pathological characteristics and surgical decision-making determined choice of operation not deprivation.

Immediate breast reconstruction (IBR) has been considered by some to lead to a delay in the delivery of adjuvant chemotherapy. Our aim was to determine whether IBR led to a delay when compared to conservation surgery and non-reconstructive mastectomy. Ninety-five cases of IBR receiving chemotherapy were reviewed. These were compared to 95 consecutively treated patients undergoing conservation surgery and 95 undergoing non-reconstructive mastectomy. Our data shows that IBR does not lead to a delay in the delivery of adjuvant chemotherapy when compared to standard non-reconstructive surgery and should not adversely affect breast cancer outcome.

Background: As a consequence of mammographic breast screening programmes, ductal carcinoma in situ is diagnosed with increasing frequency. Mastectomy for localised ductal carcinoma in situ is thought to be an over-treatment by many physicians, but there is much controversy as to whether complete local excision alone is sufficient. We aimed to assess the effectiveness of adjuvant radiotherapy and tamoxifen., Methods: We used a 2x2 factorial design in a randomised controlled trial. Between May, 1990, and August, 1998, 1701 patients recruited from screening programmes were randomised to both treatments in combination or singly, or to none, or to either one (eg, radiotherapy) with an elective decision to give or to withhold the other (ie, in this case tamoxifen). Patients had complete surgical excision of the lesion confirmed by specimen radiography and histology. Patients have been followed up at least once a year. Median follow-up was 52.6 (range 2.4-118.3) months. Our primary endpoint was the incidence of ipsilateral invasive disease., Findings: Ipsilateral invasive disease was not reduced by tamoxifen but recurrence of overall ductal carcinoma in situ was decreased (hazard ratio 0.68 [0.49-0.96]; p=0.03). Radiotherapy reduced the incidence of ipsilateral invasive disease (0.45 [0.24-0.85]; p=0.01) and ipsilateral ductal carcinoma in situ (0.36 [0.19-0.66]; p=0.0004), but there was no effect on the occurrence of contralateral disease. There was no evidence of interaction between radiotherapy and tamoxifen., Interpretation: Radiotherapy can be recommended for patients with ductal carcinoma in situ treated by complete local excision; however, there is little evidence for the use of tamoxifen in these women.

Background: The assessment of axillary nodal status remains divisive: inaccurate staging may result in untreated axillary disease, and appropriate adjuvant therapy not being delivered. The impact of inadequate axillary treatment on survival remains controversial. We analyse the impact of failure to adequately assess the axillary nodal status on survival., Methods: All women with confirmed breast cancer in a 15-year period were identified, and the original pathology reports examined, and details of radiotherapy obtained. The survival of women by axillary sample size was compared to a reference group of women and corrected for nodal status, tumour size, age, deprivation category and speciality of treating surgeon., Findings: Sampling less than four nodes is associated with a significantly increased risk of death. This cannot be due to understaging the extent of axillary disease nor is fully explainable by differential prescription of adjuvant therapies. We conclude that the survival of the women studied may have been adversely effected by inadequate axillary treatment.

Epidemiologists have established that women with small families, and particularly nulliparae, are prone to develop breast cancer later in life. We report that physiological mammary hypervascularity may be an intermediate reason against the background that breast-core vascularity is normal in pregnancy but pathological in the vascularisation of cancer. We examined breast 'core' vascularity in nulliparae during their potential reproductive life and in parous women after their last birth but before their menopause. Fifty clinically normal pre-menopausal non-pregnant women (100 breasts) were studied daily for one 'luteal positive' menstrual cycle. Their parity history varied from zero to five babies. Under controlled domestic conditions each wore a special electronic thermometric bra to automatically record breast 'core' temperature changes as a measure of mammary tissue blood flow. In the nulliparae there was a rise of breast vascularity throughout reproductive life. In the parous women, a year or so after each birth, breast vascularity was reset at a lower level than before the pregnancy; thereafter, as in nulliparae, there was progressive increase in mammary vascularity until the menopause.
