Optimum duration of neoadjuvant letrozole to permit breast conserving surgery.

The aim of this multicenter, prospective, longitudinal phase IV study was to establish the optimal duration of neoadjuvant letrozole that would allow breast conservation surgery (BCS) in patients with early breast cancer who were initially unsuitable. Primary, invasive, estrogen-receptor- and/or progesterone-receptor-positive breast cancer patients, with large tumors (≥T2 i.e., >20 mm) not initially suitable for BCS, received 2.5 mg letrozole p.o. daily. Patients continued treatment until they became eligible for BCS, progressed, failed to meet criteria for BCS and withdrew for scheduled mastectomy, withdrew for other reasons, or completed 12 months of letrozole treatment without a BCS decision being made. A total of 146 patients were enrolled; seven patients who did not have a valid postbaseline tumor assessment were excluded from the final efficacy analysis. At study closure, 69 % of patients (96 of 139) were eligible for BCS. The median time to achieve a tumor response sufficient to allow BCS with neoadjuvant letrozole was 7.5 months (95 % CI 6.3-8.5 months). Letrozole was well tolerated, and most adverse events were mild-to-moderate (grade 1-2). The results from this trial suggest that extended letrozole therapy in the neoadjuvant setting (7.5 months), as opposed to conventional treatment of 4 months, is optimal to achieve maximum reduction in tumor volume sufficient for BCS.

The relationship between lymphovascular invasion and angiogenesis, hormone receptors, cell proliferation and survival in patients with primary operable invasive ductal breast cancer.

BACKGROUND: Several well-established tumour prognostic factors are used to guide the clinical management of patients with breast cancer. Lymphovascular invasion and angiogenesis have also been reported to have some promise as prognostic factors. The aim of the present study was to examine the prognostic value of tumour lymphovascular invasion and microvessel density compared with that of established prognostic factors in invasive ductal breast cancer. METHODS: In addition to hormone receptor status and Ki-67 proliferative activity, lymphovascular invasion and microvessel density and their relationship with survival were examined in patients with invasive ductal breast cancer. Full sections and tissue microarrays (n = 384 patients) were utilised to assess these factors and were scored by appropriate methods. RESULTS: On univariate analysis tumour size (P < 0.05), lymph node involvement (P < 0.01), lymphovascular invasion (P < 0.05), microvessel density (P < 0.05) and local- regional treatment (P < 0.01) were associated with poorer survival in ER negative tumours. On multivariate analysis in ER negative tumours lymph node involvement (P < 0.01) and local- regional treatment (P < 0.05) were independently associated with poorer cancer-specific survival. On univariate analysis tumour grade (P < 0.05), lymph node involvement (P < 0.001), HER-2 (P < 0.05), Ki-67 (P < 0.01) and lymphovascular invasion (P < 0.001) were associated with poorer survival in ER positive tumours. On multivariate analysis lymph node involvement (P < 0.001), Ki-67 (P < 0.001) and lymphovascular invasion (P < 0.05) were independently associated with poorer cancer-specific survival in ER positive tumours. CONCLUSION: Lymphovascular invasion but not microvessel density was independently associated with poorer survival in patients with ER positive but not ER negative invasive ductal breast cancer.

Comparison of visual and automated assessment of HER2 status and their impact on outcome in primary operable invasive ductal breast cancer.

AIMS: To compare visual and computerized image analysis of HER2 immunohistochemistry (IHC) with fluorescence in-situ hybridization (FISH) for HER2 status, and to examine the relationships with outcome in patients with primary operable invasive ductal breast cancer. METHODS AND RESULTS: Tissue microarrays for 431 breast cancer patients were used to compare different approaches to the assessment of HER2 status. The cores were scored visually and with the Slidepath Tissue IA system, using the NICE-approved scoring system for the HercepTest, as well as by FISH. The agreement between visual and image analysis of HER2 IHC was excellent [interclass correlation coefficient (ICCC) = 0.95, rs = 0.90, r = 0.91, k = 0.81, and P < 0.001]. The agreement of HER2 FISH with visual and image analysis of HER2 IHC was also excellent (ICCC = 0.95 and ICCC = 0.92, respectively). Univariate survival analysis showed equivalent associations of visual and image analysis of HER2 and HER2 FISH with both recurrence-free survival (all P < 0.01) and cancer-specific survival (all P < 0.05) in patients with invasive ductal breast cancer. CONCLUSION: Computerized image analysis of HER2 IHC gives results comparable to those obtained with visual assessment, with possible advantages in diagnostic pathology.

Breast cancer outcomes by steroid hormone receptor status assessed visually and by computer image analysis.

AIMS: To compare the assessment of steroid hormone receptor immunohistochemistry by eye and by computer-aided image analysis, and to examine their relationships with survival in breast cancer. METHODS AND RESULTS: Allred scores and weighted histoscores for oestrogen receptor (ER) and progesterone receptor (PR) immunohistochemistry were determined by eye (visual histoscore) for 459 primary invasive ductal breast carcinomas in triplicate tissue microarrays. Histoscores were also determined by computerized image analysis (automated histoscore). ER and PR status determined by these different methods were compared with each other and in their ability to predict survival over at least 142 months of follow-up. Allred and visual histoscore were highly associated for ER and PR (both P < 0.001). By univariate analysis, Allred score and visual histoscore for ER and PR were highly associated with recurrence-free and cancer-specific survival (both P < 0.001) in patients with invasive ductal breast cancer overall, in those who received tamoxifen, and in those with recurrence on tamoxifen. Visual and automated histoscores were in excellent agreement for ER and PR (both P < 0.001), and were equally effective in predicting recurrence and survival for patients with invasive breast cancer who received tamoxifen. CONCLUSIONS: Automated histoscore appears to be a valid alternative to visual histoscore or Allred score for determining ER and PR status.

When to start an aromatase inhibitor: now or later?

Among women who have undergone surgery for breast cancer, the risk of recurrence, especially distant metastases, peaks 1-2 years postsurgery. Recent clinical trial evidence suggests that initial adjuvant therapy with an aromatase inhibitor (AI) can reduce this early risk of recurrence. According to the recently updated St Gallen consensus statement, initial AI therapy is the preferred strategy for adjuvant endocrine therapy in postmenopausal women with hormone receptor-positive breast cancer.

Extreme Oncoplasty: Breast Conservation in Patients with Large, Multifocal, and Multicentric Breast Cancer.

INTRODUCTION: Extreme Oncoplastic Breast Conservation Surgery (EOBCS) is offered in selected patients with multifocal or multicentric breast cancer (MFMC). Recent evidence has suggested that EOBCS may be a valuable resource for patients with MFMC who may avoid the risk associated with mastectomy in favour of the benefits of breast conservation without risking their oncological outcomes. Our study examined the practice of EOBCS in two regional breast units in Glasgow, United Kingdom. MATERIALS AND METHODS: A prospectively collected database of 50 patients treated with EOBC in two breast units in Glasgow between 2007 and 2018 were evaluated, and clinical outcomes were observed. RESULTS: Fifty patients (median age 55) underwent EOBCS, of which 43 (86%) had invasive disease. Median tumour size was 55mm (50-90) and multifocal disease was identified in 22 (44%) patients. Nine patients (18%) were found to have positive margins and underwent a second procedure, with 6 (12%) proceeding to mastectomy. Five-year disease free survival rate was 91.5%, while cancer-specific survival was 95.7%. CONCLUSION: EOBCS is oncologically safe in short-term follow-up. Large scale studies are required to confirm these preliminary results, in order to offer EOBCS as a valid option to patients with advanced or multifocal breast cancer.

A prospective cohort study of the safety of breast cancer surgery during COVID-19 pandemic in the West of Scotland.

INTRODUCTION: In order to minimise the risk of breast cancer patients for COVID-19 infection related morbidity and mortality prioritisation of care has utmost importance since the onset of the pandemic. However, COVID-19 related risk in patients undergoing breast cancer surgery has not been studied yet. We evaluated the safety of breast cancer surgery during COVID-19 pandemic in the West of Scotland region. METHODS: A prospective cohort study of patients having breast cancer surgery was carried out in a geographical region during the first eight weeks of the hospital lockdown and outcomes were compared to the regional cancer registry data of pre-COVID-19 patients of the same units (n = 1415). RESULTS: 188 operations were carried out in 179 patients. Tumour size was significantly larger in patients undergoing surgery during hospital lockdown than before (cT3-4: 16.8% vs. 7.4%; p < 0.001; pT2 - pT4: 45.5% vs. 35.6%; p = 0.002). ER negative and HER-2 positive rate was significantly higher during lockdown (ER negative: 41.3% vs. 17%, p < 0.001; HER-2 positive: 23.4% vs. 14.8%; p = 0.004). While breast conservation rate was lower during lockdown (58.6% vs. 65%; p < 0.001), level II oncoplastic conservation was significantly higher in order to reduce mastectomy rate (22.8% vs. 5.6%; p < 0.001). No immediate reconstruction was offered during lockdown. 51.2% had co-morbidity, and 7.8% developed postoperative complications in lockdown. There was no peri-operative COVID-19 infection related morbidity or mortality. CONCLUSION: breast cancer can be safely provided during COVID-19 pandemic in selected patients.

Patterns and predictors of early recurrence in postmenopausal women with estrogen receptor-positive early breast cancer.

Previous studies suggest that disease recurrence peaks at around 2 years in patients with early stage breast cancer (EBC), but provide no data regarding recurrence type. This retrospective analysis aimed to identify early recurrence types and risk factors in estrogen receptor-positive (ER+) EBC patients treated with adjuvant tamoxifen following breast cancer surgery. Postmenopausal women diagnosed with ER+ EBC from 1995 to 2004 were evaluated. Annual hazard ratios (HR) for recurrence at different sites were calculated. Time-dependent Cox regression analysis was used to identify predictors of recurrence within 2.5 years of diagnosis, including factors that were more strongly predictive of early than later recurrence. Of 3,614 patients evaluated, 476 developed recurrence during the 5-year median follow-up. Cumulative recurrence rates at 2.5 years (95% confidence interval) were: overall 6.3% (5.5-7.1), locoregional 1.1% (0.7-1.5), contralateral 0.5% (0.3-0.7), and distant 4.8% (4.0-5.6). The annual HR of overall recurrence peaked at 2 years (4.3% per annum). The majority of this peak represented distant recurrence (3.4% per annum). In Cox regression analysis, tumor size and grade, lymph node involvement, lymphovascular invasion, and symptomatic presentation were significant independent predictors of early recurrence. Age at diagnosis was independently predictive of recurrence within 2.5 years of diagnosis but not later recurrence. This study identified an early recurrence peak at 2 years, most of which were distant recurrences. Implementing an aromatase inhibitor after an initial 2-3 years of tamoxifen fails to address this early peak of distant recurrence and the potential breast cancer-associated mortality.

Variation in the management of elderly patients in two neighboring breast units is due to preferences and attitudes of health professionals.

Introduction: Elderly breast cancer patients have been shown to be managed less aggressively than younger patients. There is evidence that their management varies between institutions. We audited the management of elderly patients in two neighboring units in Glasgow and aimed to identify reasons for any differences in practice found. Methods: Patients aged ≥70 years, who were managed for a new diagnosis of breast cancer in the two units between 2009 and 2013, were identified from a prospectively maintained database. Tumor pathology, treatment details, postcode and consultant in charge of care were obtained from the same database. Comorbidities were obtained from each patient's electronic clinical record. Questionnaires were distributed to members of each multidisciplinary teams. Results: 487 elderly patients in Unit 1 and 467 in Unit 2 were identified. 76.2% patients in Unit 1 were managed surgically compared to 63.7% in Unit 2 (p<0.0001). There was no difference between the two units in patient age, tumor pathology, deprivation or comorbidity. 16.2% patients managed surgically in Unit 1 had a comorbidity score of 6 and above compared to 11% of surgically managed patients in Unit 2 (p=0.036). Responses to questionnaires suggested that staff at Unit 1 were more confident of the safety of general anesthetic in elderly patients and were more willing to consider local anesthetic procedures. Conclusion: A higher proportion of patients aged >70 years with breast cancer were managed surgically in Unit 1 compared to Unit 2. Reasons for variation in practice seem to be related to attitudes of medical professionals toward surgery in the elderly, rather than patient or pathological factors.

Oncoplastic breast conservation occupies a niche between standard breast conservation and mastectomy - A population-based prospective audit in Scotland.

INTRODUCTION: The role of oncoplastic breast conservation (OBC) surgery is not fully defined in terms of whether it is equivalent to standard breast conservation (SBC), or more an alternative to mastectomy, or whether it occupies its own niche somewhere between the two. Therefore, we have carried out a population-based prospective audit of the current OBC practice in Scotland. METHODS: All patients diagnosed with breast cancer in the whole of Scotland between 01/01/2014 and 31/12/2015 were prospectively recorded within the National Managed Clinical Networks databases. Patients treated with OBC were compared to patients who had SBC, mastectomy and mastectomy with immediate reconstruction (MIR). RESULTS: 8075 patients were included (OBC:217(2.7%); SBC:5241(64.9%); mastectomy:1907(23.6%); MIR:710(8.8%)). OBC patients were younger than SBC or mastectomy, but older than MIR (p < 0.0001). OBC patients were between SBC and mastectomy patients in terms of clinical and pathological tumour size (all p < 0.001), rates of lobular cancers (v.SBC:p = 0.015 and v.mastectomy:p < 0.001), high-grade tumours (v.SBC:p = 0.030 and v.mastectomy:p = 0.008), ER negative (v.SBC: p = 0.042) and HER-2 positive (v.SBC: p = 0.003) tumours, and nodal metastasis (v.mastectomy: p < 0.001). More OBC patients received (neo)adjuvant chemo- and hormonal therapy (p ≤ 0.001), adjuvant radiotherapy (p = 0.005), trastuzumab (p < 0.001) than SBC. More OBC patients presented through screening (v.mastectomy/MIR: p < 0.0001). Time to surgery from diagnosis was longer for OBC than SBC/mastectomy (p < 0.0001), but shorter than MIR (p = 0.007). CONCLUSION: This national audit demonstrates that OBC occupies its own niche between SBC, mastectomy and MIR in the surgical treatment of breast cancer in Scotland. We recommend that OBC should be recorded separately in other national breast cancer registries.

Guidance for the management of breast cancer treatment-induced bone loss: a consensus position statement from a UK Expert Group.

In postmenopausal women, the use of aromatase inhibitors increases bone turnover and induces bone loss at sites rich in trabecular bone at an average rate of 1-3% per year leading to an increase in fracture incidence compared to that seen during tamoxifen use. The bone loss is much more marked in young women with treatment-induced ovarian suppression followed by aromatase inhibitor therapy (average 7-8% per annum). Pre-treatment with tamoxifen for 2-5 years may reduce the clinical significance of the adverse bone effects associated with aromatase inhibitors, particularly if this leads to a shortening in the duration of exposure to an aromatase inhibitor. However, skeletal status should still be assessed at the commencement of aromatase inhibitor therapy. The rate of bone loss in women who experience a premature menopause before the age of 45 or are receiving ovarian suppression therapy is accelerated by the concomitant use of aromatase inhibitors. These patients are considered to be at high risk of clinically important bone loss and should have a baseline dual energy X-ray absorptiometry (DXA) assessment of bone mineral density (BMD). Randomised clinical trials in postmenopausal women indicate that bisphosphonates prevent the bone loss and accelerated bone turnover associated with aromatase inhibitor therapy and are a promising strategy for the prevention and treatment of osteoporosis in this setting. Treatment initiation recommendations are based on a combination of risk factors for osteoporotic fracture and BMD levels. Bisphosphonates, along with a healthy lifestyle and adequate intake of calcium and vitamin D are the treatments of choice to prevent bone loss. Due to the rate of bone loss associated with breast cancer treatments, and uncertainties about the interaction between aromatase inhibitor use and BMD for fracture risk, the threshold for intervention has been set at a higher level than that generally recommended for postmenopausal osteoporosis. Management recommendations have been summarised in two algorithms, one for women experiencing a premature menopause and the other for postmenopausal women requiring adjuvant aromatase inhibitor therapy.

The SANAD study of effectiveness of carbamazepine, gabapentin, lamotrigine, oxcarbazepine, or topiramate for treatment of partial epilepsy: an unblinded randomised controlled trial.

BACKGROUND: Carbamazepine is widely accepted as a drug of first choice for patients with partial onset seizures. Several newer drugs possess efficacy against these seizure types but previous randomised controlled trials have failed to inform a choice between these drugs. We aimed to assess efficacy with regards to longer-term outcomes, quality of life, and health economic outcomes. METHODS: SANAD was an unblinded randomised controlled trial in hospital-based outpatient clinics in the UK. Arm A recruited 1721 patients for whom carbamazepine was deemed to be standard treatment, and they were randomly assigned to receive carbamazepine, gabapentin, lamotrigine, oxcarbazepine, or topiramate. Primary outcomes were time to treatment failure, and time to 12-months remission, and assessment was by both intention to treat and per protocol. This study is registered as an International Standard Randomised Controlled Trial, number ISRCTN38354748. FINDINGS: For time to treatment failure, lamotrigine was significantly better than carbamazepine (hazard ratio [HR] 0.78 [95% CI 0.63-0.97]), gabapentin (0.65 [0.52-0.80]), and topiramate (0.64 [0.52-0.79]), and had a non-significant advantage compared with oxcarbazepine (1.15 [0.86-1.54]). For time to 12-month remission carbamazepine was significantly better than gabapentin (0.75 [0.63-0.90]), and estimates suggest a non-significant advantage for carbamazepine against lamotrigine (0.91 [0.77-1.09]), topiramate (0.86 [0.72-1.03]), and oxcarbazepine (0.92 [0.73-1.18]). In a per-protocol analysis, at 2 and 4 years the difference (95% CI) in the proportion achieving a 12-month remission (lamotrigine-carbamazepine) is 0 (-8 to 7) and 5 (-3 to 12), suggesting non-inferiority of lamotrigine compared with carbamazepine. INTERPRETATION: Lamotrigine is clinically better than carbamazepine, the standard drug treatment, for time to treatment failure outcomes and is therefore a cost-effective alternative for patients diagnosed with partial onset seizures.

The SANAD study of effectiveness of valproate, lamotrigine, or topiramate for generalised and unclassifiable epilepsy: an unblinded randomised controlled trial.

BACKGROUND: Valproate is widely accepted as a drug of first choice for patients with generalised onset seizures, and its broad spectrum of efficacy means it is recommended for patients with seizures that are difficult to classify. Lamotrigine and topiramate are also thought to possess broad spectrum activity. The SANAD study aimed to compare the longer-term effects of these drugs in patients with generalised onset seizures or seizures that are difficult to classify. METHODS: SANAD was an unblinded randomised controlled trial in hospital-based outpatient clinics in the UK. Arm B of the study recruited 716 patients for whom valproate was considered to be standard treatment. Patients were randomly assigned to valproate, lamotrigine, or topiramate between Jan 12, 1999, and Aug 31, 2004, and follow-up data were obtained up to Jan 13, 2006. Primary outcomes were time to treatment failure, and time to 1-year remission, and analysis was by both intention to treat and per protocol. This study is registered as an International Standard Randomised Controlled Trial, number ISRCTN38354748. FINDINGS: For time to treatment failure, valproate was significantly better than topiramate (hazard ratio 1.57 [95% CI 1.19-2.08]), but there was no significant difference between valproate and lamotrigine (1.25 [0.94-1.68]). For patients with an idiopathic generalised epilepsy, valproate was significantly better than both lamotrigine (1.55 [1.07-2.24] and topiramate (1.89 [1.32-2.70]). For time to 12-month remission valproate was significantly better than lamotrigine overall (0.76 [0.62-0.94]), and for the subgroup with an idiopathic generalised epilepsy 0.68 (0.53-0.89). But there was no significant difference between valproate and topiramate in either the analysis overall or for the subgroup with an idiopathic generalised epilepsy. INTERPRETATION: Valproate is better tolerated than topiramate and more efficacious than lamotrigine, and should remain the drug of first choice for many patients with generalised and unclassified epilepsies. However, because of known potential adverse effects of valproate during pregnancy, the benefits for seizure control in women of childbearing years should be considered.

A population-based audit of surgical practice and outcomes of oncoplastic breast conservations in Scotland - An analysis of 589 patients.

INTRODUCTION: Current evidence for oncoplastic breast conservation (OBC) is based on single institutional series. Therefore, we carried out a population-based audit of OBC practice and outcomes in Scotland. METHODS: A predefined database of patients treated with OBC was completed retrospectively in all breast units practicing OBC in Scotland. RESULTS: 589 patients were included from 11 units. Patients were diagnosed between September 2005 and March 2017. High volume units performed a mean of 19.3 OBCs per year vs. low volume units who did 11.1 (p = 0.012). 23 different surgical techniques were used. High volume units offered a wider range of techniques (8-14) than low volume units (3-6) (p = 0.004). OBC was carried out as a joint operation involving a breast and a plastic surgeon in 389 patients. Immediate contralateral symmetrisation rate was significantly higher when OBC was performed as a joint operation (70.7% vs. not joint operations: 29.8%; p < 0.001). The incomplete excision rate was 10.4% and was significantly higher after surgery for invasive lobular carcinoma (18.9%; p = 0.0292), but was significantly lower after neoadjuvant chemotherapy (3%; p = 0.031). 9.2% of patients developed major complications requiring hospital admission. Overall the complication rate was significantly lower after neoadjuvant chemotherapy (p = 0.035). The 5 year local recurrence rate was 2.7%, which was higher after OBC for DCIS (8.3%) than invasive ductal cancer (1.6%; p = 0.026). 5-year disease-free survival was 91.7%, overall survival was 93.8%, and cancer-specific survival was 96.1%. CONCLUSION: This study demonstrated that measured outcomes of OBC in a population-based multi-centre setting can be comparable to the outcomes of large volume single centre series.

Oncological Outcomes and Complications After Volume Replacement Oncoplastic Breast Conservations-The Glasgow Experience.

INTRODUCTION: Oncoplastic breast conservation surgery (OBCS) combines the principles of surgical oncology and plastic surgery. OBCS has now become a growing option for the treatment of breast cancer and forms a part of breast-conserving therapy (BCT). We sought to investigate and report our experience in two breast units in Glasgow (Victoria Infirmary and Western Infirmary) on volume replacement OBCS. MATERIALS AND METHODS: Details of patients treated with volume replacement OBCS were identified from a prospectively recorded database from November 2010 to October 2015. The clinical records included in the oncoplastic dataset were analyzed for demographics, tumor, treatment characteristics, and recurrences. The data were analyzed for follow-up to determine the pattern and timing of recurrence up to April 2016. The primary outcome of this study was tumor-free margin resection rates, and the secondary outcomes were locoregional and distant recurrence rates as these correlate with the overall oncological safety of volume replacement oncoplastic breast surgery (OPBS). RESULTS: A total of 30 volume replacement oncoplastic breast conservation procedures have been carried out in this time period. The mean age of the former group was 51 years. Twice as many patients presented symptomatically than had tumors detected on screening. The mean preoperative tumor size on radiology was 25.4 mm. Patients underwent 13 thoracoepigastric flaps, 5 lateral intercostal artery perforator (LICAP) flaps, 2 thoracodorsal artery perforator (TDAP) flaps, 1 lateral thoracic artery perforator (LTAP) flap, 1 crescent flap volume replacement surgery, and 8 matrix rotations. Two patients had neoadjuvant chemotherapy. Fourteen patients had adjuvant chemotherapy, and all patients were treated with adjuvant radiotherapy. Twenty-two patients were treated with hormonal therapy and four patients were treated with Herceptin. The rate of incomplete excision was 10%. Median follow-up time was 48.5 months. Only one regional recurrence was detected. Eight patients encountered some form of complication. CONCLUSION: This study continues to show the relative oncological safety of volume replacement oncoplastic conservations as an option for reconstruction in breast cancer patients. Further research is urgently needed to build robust evidence supporting the long-term oncological safety.

Six-year follow-up of patients treated with oncoplastic reduction mammoplasty: A cohort study.

BACKGROUND: Current evidence for the oncological safety of oncoplastic breast conservation is poor as it is based mostly on short-term follow-up data. Hence, we report long-term recurrence rates in patients treated with oncoplastic reduction mammoplasty (ORM). METHODS: A prospectively maintained database was searched to identify patients who underwent ORM between 2005 and 2010. A retrospective review of medical records was carried out, including patients with ductal carcinoma in situ and invasive breast cancer. RESULTS: Follow-up data from 65 consecutive patients with ORM were reviewed, of which 50 patients were eligible to measure long-term recurrence rates. The average weight of the resected tissue was 272 g altogether. The mean preoperative tumour size was 2.95 cm on imaging. 64% of patients had stage II - III cancers. Incomplete excision rate after ORM was 16.1%, completion mastectomy rate was 10.7%. During a median follow-up of 72 months, 2% local, 6% distant recurrence rates were detected. The breast cancer-specific survival rate was 96% per cent. CONCLUSIONS: Based on these long-term follow-up data, ORM is an oncologically safe treatment option.

Imaging Results Following Oncoplastic and Standard Breast Conserving Surgery.

BACKGROUND: Oncoplastic breast-conserving surgery (OBCS) requires more complex surgical techniques than standard wide local excision (WLE) and the postoperative complication rate may be higher. Since these can have an impact on postoperative imaging, we compared imaging and biopsy results after OBCS and WLE. METHODS: Findings for patients undergoing OBCS (n = 83) or standard WLE (n = 128) were compared. Numbers, indications and outcomes of mammograms, breast ultrasounds, magnetic resonance imaging scans and biopsies done within 2 years after surgery were analysed. RESULTS: OBCS was applied for more advanced malignancy. Significantly more patients required breast ultrasound after OBCS than WLE (20/71 vs. 17/116; p = 0.024). Breast Imaging Reporting and Data System (BI-RADS) category 3 or 4 ultrasound results were found only in patients with OBCS (6/29 vs. 0/19; p = 0.034). Significantly more biopsies were required after OBCS (9/71 vs. 3/116; p = 0.006). New lumps or lumpiness were the commonest indications, and pathology confirmed fat necrosis in the majority (7/12). The rate of fat necrosis after OBCS was 18% on clinical examination (13/71), 15% with ultrasound (11/71) and 7% confirmed on pathology (5/71). CONCLUSION: Patients treated with OBCS require significantly more ultrasound scans and consequent biopsies than patients who underwent WLE. This is mainly due to fat necrosis developing after OBCS in the majority of cases.

Use of a visual analogue scale in a daily patient diary: modelling cross-sectional time-series data on health-related quality of life.

An economic evaluation of beta interferon therapy collected quality of life data from 62 people with relapsing-remitting multiple sclerosis, currently in remission. Each completed a postal questionnaire consisting of the Euroqol EQ-5D questionnaire, the MSQOL-54 (a disease-specific measure incorporating the SF36) and other data including health services use. This was completed at the beginning and end of 6-weeks during which a daily diary was kept. The diary asked about daily activities, symptoms experienced, the impact of symptoms, general health status and current health status using the Euroqol Visual Analogue Scale (EQ VAS). The diary had an excellent completion rate, producing data with good face validity. The resulting cross-sectional time-series data provide information about the stability and variability of the EQ VAS in repeated measurement and its sensitivity to health state changes. EQ VAS scores were stable at the population level over time; greater variation in scores was observed between rather than within individuals. Panel data techniques are used to relate EQ VAS scores to recorded symptoms and baseline general health status, paying particular attention to the role of individual heterogeneity and the dynamic nature of responses. The EQ VAS was sensitive to the presence of symptoms, their severity and their type. It is concluded that appropriately analysed panel data can provide insights useful in the measurement of health-related quality of life.

[Level of knowledge about epilepsy among Polish patients with epilepsy and their families in the European study SPOKE (Sanofi-Synthelabo Programme for Outcome Knowledge of Epilepsy)]. / Poziom wiedzy na temat padaczki wsród polskich pacjentów i ich rodzin w badaniu europejskim SPOKE (Sanofi-Synthelabo Programme for Outcome Knowledge of Epilepsy).

BACKGROUND AND PURPOSE: The main aim of the European Study SPOKE (Sanofi-Synthelabo Programme for Outcome Knowledge of Epilepsy) designed by the Department of Neurosciences, Walton Hospital in Liverpool and the Centre for Health Services Research at the University of Newcastle upon Tyne, England, was to describe levels of knowledge about epilepsy among people with epilepsy and their families. It was equally important to identify gaps in understanding the most important aspects of the illness as well as to identify characteristics of people who score poorly on the Epilepsy Knowledge Questionnaire (EKQ). Another aim was to consider the implications of identified gaps in knowledge for future educational and psychosocial interventions. MATERIAL AND METHODS: The study was conducted in 10 European countries and included 6156 people with epilepsy and 6506 members of their families. Results presented here relate to data for Poland only, where the examined population consisted of 1028 patients with epilepsy. 1033 questionnaires were returned by carers. RESULTS: Over 40% of all respondents had frequent seizures, and one third were seizure free. Scores on the Epilepsy Knowledge Questionnaire were high for the majority of respondents, but generally lower than in most of the countries. With reference to some aspects of illness important gaps in knowledge have been demonstrated. For example, it was shown that a significant number of respondents provided incorrect answers to questions relating to aspects of the etiology of epilepsy and administration of antiepileptic drug medication. There were a number of significant differences between the profiles of high and low scorers on the EKQ; high scorers were likely to have spent longer on education, have lower scores on the impact of epilepsy scale and report better adjustment to their epilepsy. CONCLUSIONS: The results of the study once again underline the importance of continued information among patients with epilepsy and their families in order to achieve.
