Abstract
PURPOSE To identify the individual genes or gene modules that lead to the OncoptypeDx 21-gene recurrence score's reduced performance after 5 years and thereby identify indices of residual risk that may guide selection of patients for extended adjuvant therapy. EXPERIMENTAL DESIGN We conducted a retrospective assessment of the relationship between (i) the individual genes and gene modules of the Recurrence Score and (ii) early (0-5 years) and late (5-10 years) recurrence rates in 1,125 postmenopausal patients with primary estrogen receptor-positive breast cancer treated with anastrozole or tamoxifen in the Arimidex, Tamoxifen, Alone or Combined (ATAC) randomized clinical trial. RESULTS In the HER2-negative population (n = 1,009), estimates of recurrence risk were similar between years 0-5 and 5-10 for proliferation and invasion modules but markedly different for the estrogen module and genes within it (all split at the median): for low estrogen module, annual recurrence rates were similar across the two time windows (2.06% vs. 2.46%, respectively); for high estrogen module, annual rates were 1.14% versus 2.72%, respectively (P interaction = 0.004). Estrogen receptor transcript levels showed inverse prediction across the time windows: HR, 0.88 (0.73-1.07) and 1.19 (0.99-1.43), respectively (P interaction = 0.03). Similar time-, module-, and estrogen-dependent relationships were seen for distant recurrence. CONCLUSIONS Patients with tumors with high estrogen receptor transcript levels benefit most from 5 years' endocrine therapy but show increased recurrence rates after 5 years and may benefit from extended therapy. Improved prognostic profiles may be created by considering period of treatment and follow-up time.

Abstract
IMPORTANCE Critical illness results in disability and reduced health-related quality of life (HRQOL), but the optimum timing and components of rehabilitation are uncertain. OBJECTIVE To evaluate the effect of increasing physical and nutritional rehabilitation plus information delivered during the post-intensive care unit (ICU) acute hospital stay by dedicated rehabilitation assistants on subsequent mobility, HRQOL, and prevalent disabilities. DESIGN, SETTING, AND PARTICIPANTS A parallel group, randomized clinical trial with blinded outcome assessment at 2 hospitals in Edinburgh, Scotland, of 240 patients discharged from the ICU between December 1, 2010, and January 31, 2013, who required at least 48 hours of mechanical ventilation. Analysis for the primary outcome and other 3-month outcomes was performed between June and August 2013; for the 6- and 12-month outcomes and the health economic evaluation, between March and April 2014. INTERVENTIONS During the post-ICU hospital stay, both groups received physiotherapy and dietetic, occupational, and speech/language therapy, but patients in the intervention group received rehabilitation that typically increased the frequency of mobility and exercise therapies 2- to 3-fold, increased dietetic assessment and treatment, used individualized goal setting, and provided greater illness-specific information. Intervention group therapy was coordinated and delivered by a dedicated rehabilitation practitioner. MAIN OUTCOMES AND MEASURES The Rivermead Mobility Index (RMI) (range 0-15) at 3 months; higher scores indicate greater mobility. Secondary outcomes included HRQOL, psychological outcomes, self-reported symptoms, patient experience, and cost-effectiveness during a 12-month follow-up (completed in February 2014). RESULTS Median RMI at randomization was 3 (interquartile range [IQR], 1-6) and at 3 months was 13 (IQR, 10-14) for the intervention and usual care groups (mean difference, -0.2 [95% CI, -1.3 to 0.9; P = .71]). The HRQOL scores were unchanged by the intervention (mean difference in the Physical Component Summary score, -0.1 [95% CI, -3.3 to 3.1; P = .96]; and in the Mental Component Summary score, 0.2 [95% CI, -3.4 to 3.8; P = .91]). No differences were found for self-reported symptoms of fatigue, pain, appetite, joint stiffness, or breathlessness. Levels of anxiety, depression, and posttraumatic stress were similar, as were hand grip strength and the timed Up & Go test. No differences were found at the 6- or 12-month follow-up for any outcome measures. However, patients in the intervention group reported greater satisfaction with physiotherapy, nutritional support, coordination of care, and information provision. CONCLUSIONS AND RELEVANCE Post-ICU hospital-based rehabilitation, including increased physical and nutritional therapy plus information provision, did not improve physical recovery or HRQOL, but improved patient satisfaction with many aspects of recovery.

Abstract
Infiltration of the tumor microenvironment by nerve fibers is an understudied aspect of breast carcinogenesis. In this study, the presence of nerve fibers was investigated in a cohort of 369 primary breast cancers (ductal carcinomas in situ, invasive ductal and lobular carcinomas) by immunohistochemistry for the neuronal marker PGP9.5. Isolated nerve fibers (axons) were detected in 28% of invasive ductal carcinomas as compared to only 12% of invasive lobular carcinomas and 8% of ductal carcinomas in situ (p = 0.0003). In invasive breast cancers, the presence of nerve fibers was observed in 15% of lymph node negative tumors and 28% of lymph node positive tumors (p = 0.0031), indicating a relationship with the metastatic potential. In addition, there was an association between the presence of nerve fibers and the expression of nerve growth factor (NGF) in cancer cells (p = 0.0001). In vitro, breast cancer cells were able to induce neurite outgrowth in PC12 cells, and this neurotrophic activity was partially inhibited by anti-NGF blocking antibodies. In conclusion, infiltration by nerve fibers is a feature of the tumor microenvironment that is associated with aggressiveness and involves NGF production by cancer cells. The potential participation of nerve fibers in breast cancer progression needs to be further considered.

Abstract
Abstract
Background: Several randomised clinical trials have shown the benefit of tamoxifen in healthy women to reduce their risk of breast cancer. Here, we report the blinded median 16 year follow-up of the IBIS-I trial to update the long-term prevention of breast cancer with tamoxifen treatment.
Methods: 7154 pre- and postmenopausal women were randomised to receive daily 20mg tamoxifen (N=3579) or matching placebo (N=3575) for 5 years. The primary endpoint of this analysis was the occurrence of breast cancer (invasive and ductal carcinoma in situ (DCIS)). Secondary endpoints included overall mortality, other cancers, and breast cancer specific mortality. Cox proportional hazard models were used to assess occurrence of breast cancer and survival. All statistical tests were two-sided.
Results: After a median of 16.2 years (IQR 14.4 to 17.7) of follow-up, a total of 589 breast cancers have been reported (tamoxifen: 246 (6.9%) vs. placebo: 343 (9.6%)). Tamoxifen reduced the incidence of all breast cancer overall by 29% (HR=0.71 (0.60-0.83), P<0.0001) (Figure 1). Invasive ER-positive (ER+) breast cancers were reduced by 35% (HR=0.65 (0.53-0.80), P<0.0001) (Figure 1), but no effect was seen for invasive ER-negative (ER-) breast cancers (HR=1.06 (0.71-1.58), P=0.8). A non-significant 30% reduction in DCIS was seen with tamoxifen (36 vs. 51, HR=0.70 (0.46-1.07); P=0.1). The overall risk reduction was similar in years 0-10 (HR=0.71) and years 10-20 (HR=0.70). Similar effects were seen in pre- and postmenopausal women (HR 0.71 vs. 0.71). All-cause mortality was non-significantly increased in women randomised to tamoxifen (173 vs. 158, OR=1.10 (0.88-1.38), P=0.4). The excess in deaths with tamoxifen is smaller than in the 96 month update. No differences in breast cancer mortality was seen (24 tamoxifen vs. 27 placebo; OR=0.89 (0.49-1.60), P=0.7). A non-significant increase in other cancers than breast were reported by women on tamoxifen (350 vs. 315, OR=1.12 (0.95-1.32); P=0.2). Specifically more endometrial cancers (28 vs. 17), non-melanoma skin cancers (108 vs. 85), and lung cancer (32 vs. 20) were found in those randomised to tamoxifen.
Conclusion: This updated analysis of the IBIS-I trial confirms the significant reduction in breast cancer occurrence with tamoxifen in the post-treatment follow-up period. These results indicate tamoxifen has a long-term preventive effect on invasive ER+ breast cancer in both pre- and postmenopausal women.

Abstract
Abstract
Background
Industry-sponsored clinical trials often have duration of patient follow-up that is defined according to regulatory requirements. However, in diseases such as endocrine-responsive, early breast cancer, recurrences occur after protocol follow-up, and monitoring of long-term toxicity is important. It is challenging to continue patient follow-up after industry sponsorship ends. Transferring responsibility for additional follow-up to the participating academic centers is required. One such example is the long-term follow-up (LTFU) of patients in the Breast International Group (BIG) 1-98 Trial. We present the procedures and current status of the BIG 1-98 LTFU protocol.
Methods
In 2010, the BIG 1-98 trial embarked on a new LTFU protocol to gather data on patient outcomes for an additional five years after study completion (2011-2015). Industry sponsorship ceased at the end of 2010. The LTFU study is designed as an observational, non-interventional study to continue the collection of simplified and updated data on survival, disease status, and long-term adverse events from centers participating in the 4-arm option. The International Breast Cancer Study Group (IBCSG) is sponsoring BIG 1-98 LTFU, and per case reimbursement is available.
Results
The potential BIG 1-98 LTFU cohort consists of the 148 academic medical centers that participated in the 4-arm option with a maximum of 6843 patients enrolled to the parent study. In May 2014, approximately 3 years after initiation of the LTFU protocol, 96 centers had agreed to participate, of which 67 sites had activated the protocol and submitted LTFU data; 31 additional centers were not participating, and the status of 21 centers was unknown.

Because the original BIG 1-98 informed consent indicated life-long follow-up, only three countries required patient re-consent in order to participate. At least one LTFU data submission has occurred for 73% of patients participating in the LTFU (May 2014).
Conclusion
Long-term follow-up for a large-scale clinical trial is feasible, but challenging. The methods used for BIG 1-98 LTFU will be described and the status will be updated at the meeting.

Abstract
Abstract
Background: Cognitive impairment is a potential side-effect of breast cancer (BC) treatment. Estrogen is an important neuromodulator that affects cognition. Estrogen depletion by oophorectomy or GnRH agonists may adversely affect cognition in non-oncological settings, but there are few data regarding the cognitive effects of ovarian function suppression (OFS) in women with breast cancer.
Patients and Methods: Between November 2003 and January 2011, 3066 premenopausal women with hormone receptor-positive BC were randomised on the SOFT trial to 5 years of adjuvant endocrine therapy with tamoxifen alone, tamoxifen+OFS or exemestane+OFS. OFS was achieved by the GnRH agonist triptorelin, oophorectomy or ovarian irradiation. Prior chemotherapy was allowed, provided women had premenopausal estradiol levels at enrolment. Women eligible for Co-SOFT must not have received any prior adjuvant endocrine therapy. At study entry (t1), and approximately 1 year after SOFT randomisation (t2), objective cognitive function was assessed with a brief computerized test battery comprising 7 tasks (CogState Ltd: cogstate.com). Subjective cognitive function, psychological distress, fatigue, insomnia and quality of life were also assessed. Co-SOFT recruited 86 of a planned 321 patients from 27 of 426 SOFT centres between November 2007 and January 2011, when Co-SOFT was closed as the SOFT trial completed accrual. The protocol-specified primary comparison was the change in the composite score of the CogState tasks over 1 year for women randomised to tamoxifen versus tamoxifen+OFS. However, due to low accrual this was modified, prior to any analysis, to compare the tamoxifen versus the pooled tamoxifen+OFS and exemestane+OFS groups. Cognitive test scores were standardized according to age-specific norms, averaged to compute the composite score and then change between t1 and t2 calculated; a negative change in composite score indicates deterioration in cognitive function. Change in composite score was compared using Wilcoxon rank sum test.
Results: Of 86 Co-SOFT enrolled patients, 74 underwent both t1 and t2 CogState testing and were included in the primary analysis (7 withdrew consent/declined assessment, 5 missed testing due to scheduling). Of these 74 women, 20 were randomised to tamoxifen and 54 to OFS+tamoxifen (28) or OFS+exemestane (26). Baseline characteristics were well balanced between the 2 groups. During the first year 49 women utilised GnRH alone for OFS, 4 had GnRH followed by oophorectomy and 1 had oophorectomy alone. There was no significant difference in the changes in the CogState composite scores from t1 and t2 for patients randomised to tamoxifen alone compared with OFS+oral endocrine therapy (median, -0.057 versus -0.146 respectively, p=0.51). There were no significant between-group differences in the changes from t1 and t2 for any of the 7 individual cognitive tasks comprising the composite score.
Conclusions: The results of this 1-year longitudinal substudy suggest that the addition of OFS to oral endocrine therapy does not significantly affect cognitive function in the setting of adjuvant BC treatment. Co-SOFT was limited by small sample size, so further investigation of the impact of OFS on cognitive function in BC patients is warranted.

Abstract
Abstract
Background: Arthralgia is a well known side effect of aromatase inhibitors and low oestrogen levels and postmenopausal status are associated with this event. Anastrozole reduced the incidence of oestrogen receptor positive, invasive breast cancer by 58% in the IBIS-II trial. However, timing, severity and risk factors for arthralgia have not been assessed in detail in this trial.
Methods: The IBIS-II trial randomised postmenopausal women at high risk to receive 1mg anastrozole or matching placebo for 5 years. Date of occurrence of arthralgia along with severity (mild, moderate, severe) were recorded at each yearly follow-up visit. Age, body mass index (BMI), and previous hormone replacement therapy (HRT) were investigated as potential risk factors for arthralgia. All analyses were done by the use of logistic regression.
Results: 3864 postmenopausal women (anastrozole: 1920, placebo: 1944) were enrolled in the IBIS-II trial. 58.5% of women randomised to anastrozole reported arthralgia at any time during the trial compared with 52.8% on placebo (OR=1.26 (1.11-1.43), P=0.0004). The majority of arthralgias were reported within the first 18 months of randomisation, with a decline thereafter (Table). 17.5% of women who reported arthralgia withdrew from the trial compared to 13.9% without any of these symptoms (OR=1.31 (1.10-1.57)), and the withdrawal was significantly greater for those with severe symptoms compared to mild (OR=5.97 (4.27-8.33)). Women who used HRT before trial entry had a significant higher risk of developing arthralgia than their counterparts irrespective of allocated treatment (OR=1.45 (1.27-1.64), P<0.001). Increasing BMI (lowest vs. highest BMI group: OR=1.30 (1.11-1.53)) and age (lowest vs. highest age group: OR=1.23 (1.01-1.50)) were also significant risk factors for arthralgia. HRT and BMI remained highly significant in a multivariate model.
Conclusion: Arthalgia was common in the IBIS-II trial irrespective of treatment. However it increased in severity in the active treatment arm mainly in the 18 month period after randomisation. Severe arthralgia led to significantly more withdrawals from the trial than mild symptoms irrespective of treatment. Major risk factors for arthralgia in both arms were previous HRT use and obesity.

Abstract
ABSTRACT Kyoto Breast Cancer Consensus Conference, Kyoto, Japan, 18–20 February 2014 The loco-regional management of breast cancer is increasingly complex with application of primary systemic therapies, oncoplastic techniques and genetic testing for breast cancer susceptibility. Personalization of loco-regional treatment is integral to optimization of breast cancer care. Clinical and pathological tumor stage, biological features and host factors influence loco-regional treatment strategies and extent of surgical procedures. Key issues including axillary staging, axillary treatment, radiation therapy, primary systemic therapy (PST), preoperative hormonal therapy and genetic predisposition were identified and discussed at the Kyoto Breast Cancer Consensus Conference (KBCCC2014). In the first of a two part conference scene, consensus recommendations for axillary management are presented and focus on the following topics: indications for completion axillary lymph node dissection in primary surgical patients with ≤2 macrometastases or any sentinel nodal deposits after PST; the timing of sentinel lymph node biopsy in the context of PST; use of axillary irradiation as a component of primary treatment plans and the role of intraoperative node assessment in the post-Z0011 era.

Abstract
Abstract
Background: AIMSS is experienced by approximately half of women taking an aromatase inhibitor (AI), impairing quality of life and in some leading to AI discontinuation. There is a lack of evidence for effective AIMSS treatments.
Aim: To investigate the importance of AIMSS in Australian women with early breast cancer.
Method: A survey invitation was distributed to 2390 members of the BCNA Review and Survey Group in April 2014. The online questionnaire consisted of 45 questions covering demographics, AI use, clinical manifestations and risk factors for AIMSS, reasons for AI discontinuation and efficacy of interventions used for AIMSS. AIMSS was defined as joint pain or stiffness that developed or worsened after commencing an AI.
Results: Of 594 respondents, 370 (62%) were eligible. Reasons for exclusion were: preinvasive disease, locally advanced/metastatic breast cancer, or other reason.
Eligible respondents had a median age range of 50-59 years. Duration of AI use varied (26%1year, 64% 1-5years, 10% 5years). 57% had received adjuvant chemotherapy. 43% of these commenced AI within 3 months of chemotherapy and 30% within 3-6 months of chemotherapy. A vitamin D test was performed in 64% of women and 68% were currently using vitamin D supplements. Joint pain during menopause was reported by 22% of respondents.
AIMSS occurred in 302/370 women (81%). Of those who developed AIMSS, sites affected were feet (68%), hands or wrists (65%), knees (62%), hips (56%), shoulders or elbows (49%), back (46%), or neck (3%). 34% of women had considered stopping an AI because of AIMSS.
99 (27%) of respondents had discontinued AI for any reason and of these 68% discontinued because of AIMSS. Non-AIMSS symptoms identified as reasons for discontinuation included fatigue, vaginal/urinary symptoms and hot flushes. In respondents who discontinued AI, 20% ceased use in the first 3 months, 30% during months 3-12 and 38%12 months. 42% of respondents who discontinued an AI restarted the same or a different AI after a treatment break.
To manage AIMSS 23% of respondents used doctor prescribed medications (eg anti-inflammatories, codeine, morphine,), 55% over the counter (OTC) or complementary medicines (eg low dose anti-inflammatories, paracetamol, chondroitin, fish or krill oil, glucosamine, and vitamin D) and 29% alternative therapies (eg acupuncture, massage, Tai Chi and yoga). Respondents identified the following in each of the above categories as most successful in relieving AIMSS symptoms: doctor prescribed anti-inflammatories, paracetamol and yoga. Doctor prescribed medications and OTC/complementary medicine either completely or significantly relieved AIMSS in 12% and 25% of cases respectively. 27% of respondents found that one or more of the interventions that they had used to manage AIMSS helped prevent AI discontinuation.
Conclusion: AIMSS is a significant issue for Australian women and is an important reason for AI discontinuation. Women use a number of interventions to manage AIMSS, however their efficacy appears limited. Effective AIMSS interventions are needed, to improve quality of life and reduce AI discontinuation.

Abstract
ABSTRACT Kyoto Breast Cancer Consensus Conference, Kyoto, Japan, 18–20 February 2014 The loco-regional management of breast cancer is increasingly complex with application of primary systemic therapies, oncoplastic techniques and genetic testing for breast cancer susceptibility. Personalization of loco-regional treatment is integral to optimization of breast cancer care. Clinical and pathological tumor stage, biological features and host factors influence loco-regional treatment strategies and extent of surgical procedures. Key issues including axillary staging, axillary treatment, radiation therapy, primary systemic therapy (PST), preoperative hormonal therapy and genetic predisposition were identified and discussed at the Kyoto Breast Cancer Consensus Conference (KBCCC2014). In the second of a two part conference scene, consensus recommendations for radiation treatment, primary systemic therapies and management of genetic predisposition are reported and focus on the following topics: influence of both clinical response to PST and stage at presentation on recommendations for postmastectomy radiotherapy; use of regional nodal irradiation in selected node-positive patients and those with adverse pathological factors; extent of surgical resection following downstaging of tumors with PST; use of preoperative hormonal therapy in premenopausal women with larger, node-negative luminal A-like tumors and managing increasing demands for contralateral prophylactic mastectomy in patients with a unilateral sporadic breast cancer.

Abstract
BACKGROUND Patients undergoing vascular surgery procedures constitute a 'high-risk' group. Fatal and disabling perioperative complications are common. Complications arise via multiple aetiological pathways. This mechanistic redundancy limits techniques to reduce complications that target individual mechanisms, for example, anti-platelet agents. Remote ischaemic preconditioning (RIPC) induces a protective phenotype in at-risk tissue, conferring protection against ischaemia-reperfusion injury regardless of the trigger. RIPC is induced by repeated periods of upper limb ischaemia-reperfusion produced using a blood pressure cuff. RIPC confers some protection against cardiac and renal injury during major vascular surgery in proof-of-concept trials. Similar trials suggest benefit during cardiac surgery. Several uncertainties remain in advance of a full-scale trial to evaluate clinical efficacy. We propose a feasibility trial to fully evaluate arm-induced RIPC's ability to confer protection in major vascular surgery, assess the incidence of a proposed composite primary efficacy endpoint and evaluate the intervention's acceptability to patients and staff. METHODS/DESIGN Four hundred major vascular surgery patients in five Irish vascular centres will be randomised (stratified for centre and procedure) to undergo RIPC or not immediately before surgery. RIPC will be induced using a blood pressure cuff with four cycles of 5 minutes of ischaemia followed by 5 minutes of reperfusion immediately before the start of operations. There is no sham intervention. Participants will undergo serum troponin measurements pre-operatively and 1, 2, and 3 days post-operatively. Participants will undergo 12-lead electrocardiograms pre-operatively and on the second post-operative day. Predefined complications within one year of surgery will be recorded. Patient and staff experiences will be explored using qualitative techniques. The primary outcome measure is the proportion of patients who develop elevated serum troponin levels in the first 3 days post-operatively. Secondary outcome measures include length of hospital and critical care stay, unplanned critical care admissions, death, myocardial infarction, stroke, mesenteric ischaemia and need for renal replacement therapy (within 30 days of surgery). DISCUSSION RIPC is novel intervention with the potential to significantly improve perioperative outcomes. This trial will provide the first evaluation of RIPC's ability to reduce adverse clinical events following major vascular surgery.

Abstract
BACKGROUND Ovarian failure is a common toxic effect of chemotherapy. Studies of the use of gonadotropin-releasing hormone (GnRH) agonists to protect ovarian function have shown mixed results and lack data on pregnancy outcomes. METHODS We randomly assigned 257 premenopausal women with operable hormone-receptor-negative breast cancer to receive standard chemotherapy with the GnRH agonist goserelin (goserelin group) or standard chemotherapy without goserelin (chemotherapy-alone group). The primary study end point was the rate of ovarian failure at 2 years, with ovarian failure defined as the absence of menses in the preceding 6 months and levels of follicle-stimulating hormone (FSH) in the postmenopausal range. Rates were compared with the use of conditional logistic regression. Secondary end points included pregnancy outcomes and disease-free and overall survival. RESULTS At baseline, 218 patients were eligible and could be evaluated. Among 135 with complete primary end-point data, the ovarian failure rate was 8% in the goserelin group and 22% in the chemotherapy-alone group (odds ratio, 0.30; 95% confidence interval [CI], 0.09 to 0.97; two-sided P=0.04). Owing to missing primary end-point data, sensitivity analyses were performed, and the results were consistent with the main findings. Missing data did not differ according to treatment group or according to the stratification factors of age and planned chemotherapy regimen. Among the 218 patients who could be evaluated, pregnancy occurred in more women in the goserelin group than in the chemotherapy-alone group (21% vs. 11%, P=0.03); women in the goserelin group also had improved disease-free survival (P=0.04) and overall survival (P=0.05). CONCLUSIONS Although missing data weaken interpretation of the findings, administration of goserelin with chemotherapy appeared to protect against ovarian failure, reducing the risk of early menopause and improving prospects for fertility.

Abstract
BACKGROUND Four previously published randomised clinical trials have shown that tamoxifen can reduce the risk of breast cancer in healthy women at increased risk of breast cancer in the first 10 years of follow-up. We report the long-term follow-up of the IBIS-I trial, in which the participants and investigators remain largely masked to treatment allocation. METHODS In the IBIS-I randomised controlled trial, premenopausal and postmenopausal women 35-70 years of age deemed to be at an increased risk of developing breast cancer were randomly assigned (1:1) to receive oral tamoxifen 20 mg daily or matching placebo for 5 years. Patients were randomly assigned to the two treatment groups by telephone or fax according to a block randomisation schedule (permuted block sizes of six or ten). Patients and investigators were masked to treatment assignment by use of central randomisation and coded drug supply. The primary endpoint was the occurrence of breast cancer (invasive breast cancer and ductal carcinoma in situ), analysed by intention to treat. Cox proportional hazard models were used to assess breast cancer occurrence and mortality. The trial is closed to recruitment and active treatment is completed, but long-term follow-up is ongoing. This trial is registered with controlledtrials.com, number ISRCTN91879928. FINDINGS Between April 14, 1992, and March 30, 2001, 7154 eligible women recruited from genetics clinics and breast care clinics in eight countries were enrolled into the IBIS-I trial and were randomly allocated to the two treatment groups: 3579 to tamoxifen and 3575 to placebo. After a median follow up of 16.0 years (IQR 14.1-17.6), 601 breast cancers have been reported (251 [7.0%] in 3579 patients in the tamoxifen group vs 350 [9.8%] in 3575 women in the placebo group; hazard ratio [HR] 0.71 [95% CI 0.60-0.83], p<0.0001). The risk of developing breast cancer was similar between years 0-10 (226 [6.3%] in 3575 women in the placebo group vs 163 [4.6%] in 3579 women in the tamoxifen group; hazard ratio [HR] 0.72 [95% CI 0.59-0.88], p=0.001) and after 10 years (124 [3.8%] in 3295 women vs 88 [2.6%] in 3343, respectively; HR 0.69 [0.53-0.91], p=0.009). The greatest reduction in risk was seen in invasive oestrogen receptor-positive breast cancer (HR 0.66 [95% CI 0.54-0.81], p<0.0001) and ductal carcinoma in situ (0.65 [0.43-1.00], p=0.05), but no effect was noted for invasive oestrogen receptor-negative breast cancer (HR 1.05 [95% CI 0.71-1.57], p=0.8). INTERPRETATION These results show that tamoxifen offers a very long period of protection after treatment cessation, and thus substantially improves the benefit-to-harm ratio of the drug for breast cancer prevention.

Abstract
BACKGROUND Aromatase inhibitors prevent breast cancer in postmenopausal women at high risk of the disease but are associated with accelerated bone loss. We assessed effectiveness of oral risedronate for prevention of reduction in bone mineral density (BMD) after 3 years of follow-up in a subset of patients in the IBIS-II trial. METHODS The double-blind IBIS-II trial recruited 3864 healthy, postmenopausal women at increased risk of breast cancer and randomly allocated them oral anastrozole (1 mg/day) or matched placebo. 1410 (36%) postmenopausal women were then enrolled in a bone substudy and stratified at baseline according to their lowest baseline T score at spine or femoral neck (stratum I: T score at least -1·0; stratum II: T score at least -2·5 but less than -1·0; stratum III: T score less than -2·5 but greater than -4·0). Women in stratum I were monitored only; women in stratum III were all given risedronate (35 mg/week). Women in stratum II were randomly assigned (1:1) to risedronate (35 mg/week) or matched placebo by use of a block randomisation schedule via a web-based programme. The primary outcome of this per-protocol analysis (done with all women with a baseline and 3 year DXA assessment) was the effect of risedronate versus placebo for osteopenic women in stratum II randomly allocated to anastrozole (1 mg/day). Secondary outcomes included effect of anastrozole (1 mg/day) on BMD in women not receiving risedronate (strata I and II) and in osteoporotic women who were all treated with risedronate (stratum III). The trial is ongoing, but no longer recruiting. This trial is registered, number ISRCTN31488319. FINDINGS Between Feb 2, 2003, and Sept 30, 2010, 150 (58%) of 260 women in stratum II who had been randomly allocated to anastrozole and either risedronate or placebo had baseline and 3 year assessments. At the lumbar spine, 3 year mean BMD change for the 77 women receiving anastrozole/risedronate was 1·1% (95% CI 0·2 to 2·1) versus -2·6% (-4·0 to -1·3) for the 73 women receiving anastrozole/placebo (p<0·0001). For the total hip, 3 year mean BMD change for women receiving anastrozole/risedronate was -0·7% (-1·6 to 0·2) versus -3·5% (-4·6 to -2·3) for women receiving anastrozole/placebo (p=0·0001). 652 (65%) of 1008 women in strata I and II who were not randomly allocated to risedronate had both baseline and 3 year assessments. Women not receiving risedronate in stratum I and II who received anastrozole (310 women) had a significant BMD decrease after 3 years of follow-up compared with women who received placebo (342 women) at the lumbar spine (-4·0% [-4·5 to -3·4] vs -1·2% [-1·7 to -0·7], p<0·0001) and total hip (-4·0% [-4·4 to -3·6] vs -1·8% [-2·1 to -1·4], p<0·0001). 106 (79%) of 149 women in stratum III had a baseline and a 3 year assessment. The 46 women allocated to anastrozole had a modest BMD increase of 1·2% (-0·1 to 2·6) at the spine compared with a 3·9% (2·6 to 5·2) increase for the 60 women allocated to placebo (p=0·006). For the total hip, a small 0·3% (-0·9 to 1·5) increase was noted for women allocated anastrozole compared with a 1·5% (0·5 to 2·5) increase for women allocated placebo, but the difference was not significant (p=0·12). The most common adverse event reported was arthralgia (stratum I: 94 placebo and 114 anastrozole; stratum II: 39 placebo/placebo, 25 placebo/risedronate, 34 anastrozole/placebo, and 34 anastrozole/risedronate; stratum III: 21 placebo/risedronate, 17 anastrozole/risedronate). Other adverse events included hot flushes, alopecia, abdominal pain, and back pain. INTERPRETATION Risedronate counterbalances the effect of anastrozole-induced bone loss in osteopenic and osteoporotic women and might be offered in combination with anastrozole treatment to provide an improved risk-benefit profile.

Abstract
BACKGROUND Decision aids may improve informed consent in clinical trial recruitment, but have not been evaluated in this context. This study investigated whether decision aids (DAs) can reduce decisional difficulties among women considering participation in the International Breast Cancer Intervention Study-II (IBIS-II) trial. METHODS The IBIS-II trial investigated breast cancer prevention with anastrazole in two cohorts: women with increased risk (Prevention), and women treated for ductal carcinoma in situ (DCIS). Australia, New Zealand and United Kingdom participants were randomised to receive a DA (DA group) or standard trial consent materials (control group). Questionnaires were completed after deciding about participation in IBIS-II (post decision) and 3 months later (follow-up). RESULTS Data from 112 Prevention and 34 DCIS participants were analysed post decision (73 DA; 73 control); 95 Prevention and 24 DCIS participants were analysed at follow-up (58 DA; 61 control). There was no effect on the primary outcome of decisional conflict. The DCIS-DA group had higher knowledge post decision, and the Prevention-DA group had lower decisional regret at follow-up. CONCLUSIONS This was the first study to evaluate a DA in the clinical trial setting. The results suggest DAs can potentially increase knowledge and reduce decisional regret about clinical trial participation.

Abstract
Background Breast cancer is the most common malignancy in women world-wide. Triple negative breast cancer (TNBC) is a highly aggressive subtype that lacks expression of hormone receptors for estrogen, progesterone and human epidermal growth factor 2; and is associated with a high propensity for metastatic spread. Several studies have identified critical roles for microRNAs in breast cancer, but the role of two critical enzymes involved in microRNA biogenesis, Dicer and Drosha, is not well understood, particularly with respect to metastatic progression in this subtype. Methods We examined the expression of Dicer and Drosha in a series of invasive 35 TNBCs with matched normal adjacent tissues (n = 18) and lymph node metastases (n = 15) using semi-quantitative real time RT-PCR. The relationship of their expression with clinical features including age at diagnosis, lymph node positivity and tumour size was analysed. Results We report that Dicer was significantly decreased while Drosha was significantly increased in tumours when compared to normal adjacent tissues. While there was no difference in Drosha expression in lymph node metastases when compared to the primary tumour, Dicer was significantly increased. There was no correlation between the expression of either Dicer or Drosha to age at diagnosis, lymph node positivity and tumour size. Conclusions In conclusion, Dicer and Drosha are dysregulated in TNBC and matched lymph node metastases however, the clinical relevance of this is still not known. The altered expression of Dicer and Drosha may serve as markers for disrupted miRNA biogenesis in TNBC.

Abstract
BACKGROUND Aromatase inhibitors effectively prevent breast cancer recurrence and development of new contralateral tumours in postmenopausal women. We assessed the efficacy and safety of the aromatase inhibitor anastrozole for prevention of breast cancer in postmenopausal women who are at high risk of the disease. METHODS Between Feb 2, 2003, and Jan 31, 2012, we recruited postmenopausal women aged 40-70 years from 18 countries into an international, double-blind, randomised placebo-controlled trial. To be eligible, women had to be at increased risk of breast cancer (judged on the basis of specific criteria). Eligible women were randomly assigned (1:1) by central computer allocation to receive 1 mg oral anastrozole or matching placebo every day for 5 years. Randomisation was stratified by country and was done with blocks (size six, eight, or ten). All trial personnel, participants, and clinicians were masked to treatment allocation; only the trial statistician was unmasked. The primary endpoint was histologically confirmed breast cancer (invasive cancers or non-invasive ductal carcinoma in situ). Analyses were done by intention to treat. This trial is registered, number ISRCTN31488319. FINDINGS 1920 women were randomly assigned to receive anastrozole and 1944 to placebo. After a median follow-up of 5·0 years (IQR 3·0-7·1), 40 women in the anastrozole group (2%) and 85 in the placebo group (4%) had developed breast cancer (hazard ratio 0·47, 95% CI 0·32-0·68, p<0·0001). The predicted cumulative incidence of all breast cancers after 7 years was 5·6% in the placebo group and 2·8% in the anastrozole group. 18 deaths were reported in the anastrozole group and 17 in the placebo group, and no specific causes were more common in one group than the other (p=0·836). INTERPRETATION Anastrozole effectively reduces incidence of breast cancer in high-risk postmenopausal women. This finding, along with the fact that most of the side-effects associated with oestrogen deprivation were not attributable to treatment, provides support for the use of anastrozole in postmenopausal women at high risk of breast cancer.

Abstract
BACKGROUND The susceptibility to type 2 diabetes of people of south Asian descent is established, but there is little trial-based evidence for interventions to tackle this problem. We assessed a weight control and physical activity intervention in south Asian individuals in the UK. METHODS We did this non-blinded trial in two National Health Service (NHS) regions in Scotland (UK). Between July 1, 2007, and Oct 31, 2009, we recruited men and women of Indian and Pakistani origin, aged 35 years or older, with waist circumference 90 cm or greater in men or 80 cm or greater in women, and with impaired glucose tolerance or impaired fasting glucose determined by oral glucose tolerance test. Families were randomised (using a random number generator program, with permuted blocks of random size, stratified by location [Edinburgh or Glasgow], ethnic group [Indian or Pakistani], and number of participants in the family [one vs more than one]) to intervention or control. Participants in the same family were not randomised separately. The intervention group received 15 visits from a dietitian over 3 years and the control group received four visits in the same period. The primary outcome was weight change at 3 years. Analysis was by modified intention to treat, excluding participants who died or were lost to follow-up. We used linear regression models to provide mean differences in baseline-adjusted weight at 3 years. This trial is registered, number ISRCTN25729565. FINDINGS Of 1319 people who were screened with an oral glucose tolerance test, 196 (15%) had impaired glucose tolerance or impaired fasting glucose and 171 entered the trial. Participants were in 156 family clusters that were randomised (78 families with 85 participants were allocated to intervention; 78 families with 86 participants were allocated to control). 167 (98%) participants in 152 families completed the trial. Mean weight loss in the intervention group was 1.13 kg (SD 4.12), compared with a mean weight gain of 0.51 kg (3.65) in the control group, an adjusted mean difference of -1.64 kg (95% CI -2.83 to -0.44). INTERPRETATION Modest, medium-term changes in weight are achievable as a component of lifestyle-change strategies, which might control or prevent adiposity-related diseases.

A rehabilitation intervention to promote physical recovery following intensive care: a detailed description of construct development, rationale and content together with proposed taxonomy to capture processes in a randomised controlled trial.

[PMID: 24476530 PMCID: PMC4016544 DOI: 10.1186/1745-6215-15-38] [Citation(s) in RCA: 19] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/24/2013] [Accepted: 01/08/2014] [Indexed: 12/17/2022] Open
Abstract
BACKGROUND Increasing numbers of patients are surviving critical illness, but survival may be associated with a constellation of physical and psychological sequelae that can cause ongoing disability and reduced health-related quality of life. Limited evidence currently exists to guide the optimum structure, timing, and content of rehabilitation programmes. There is a need to both develop and evaluate interventions to support and expedite recovery during the post-ICU discharge period. This paper describes the construct development for a complex rehabilitation intervention intended to promote physical recovery following critical illness. The intervention is currently being evaluated in a randomised trial (ISRCTN09412438; funder Chief Scientists Office, Scotland). METHODS The intervention was developed using the Medical Research Council (MRC) framework for developing complex healthcare interventions. We ensured representation from a wide variety of stakeholders including content experts from multiple specialties, methodologists, and patient representation. The intervention construct was initially based on literature review, local observational and audit work, qualitative studies with ICU survivors, and brainstorming activities. Iterative refinement was aided by the publication of a National Institute for Health and Care Excellence guideline (No. 83), publicly available patient stories (Healthtalkonline), a stakeholder event in collaboration with the James Lind Alliance, and local piloting. Modelling and further work involved a feasibility trial and development of a novel generic rehabilitation assistant (GRA) role. Several rounds of external peer review during successive funding applications also contributed to development. RESULTS The final construct for the complex intervention involved a dedicated GRA trained to pre-defined competencies across multiple rehabilitation domains (physiotherapy, dietetics, occupational therapy, and speech/language therapy), with specific training in post-critical illness issues. The intervention was from ICU discharge to 3 months post-discharge, including inpatient and post-hospital discharge elements. Clear strategies to provide information to patients/families were included. A detailed taxonomy was developed to define and describe the processes undertaken, and capture them during the trial. The detailed process measure description, together with a range of patient, health service, and economic outcomes were successfully mapped on to the modified CONSORT recommendations for reporting non-pharmacologic trial interventions. CONCLUSIONS The MRC complex intervention framework was an effective guide to developing a novel post-ICU rehabilitation intervention. Combining a clearly defined new healthcare role with a detailed taxonomy of process and activity enabled the intervention to be clearly described for the purpose of trial delivery and reporting. These data will be useful when interpreting the results of the randomised trial, will increase internal and external trial validity, and help others implement the intervention if the intervention proves clinically and cost effective.

Abstract
BACKGROUND Neoadjuvant chemotherapy has a sound rationale for use in women with large operable breast cancer, and achievement of pathological complete response (pCR) is prognostic. Epirubicin and cyclophosphamide followed by docetaxel is a standard chemotherapy regimen for early breast cancer. In metastatic breast cancer the combination of gemcitabine and a taxane has shown promising results. This phase II study investigated the efficacy and safety of incorporating gemcitabine into neoadjuvant therapy. METHODS Female patients with operable breast cancer that was clinically T2 (≥3 cm) or T3-4, N0-1, M0 were enrolled to receive 24 weeks of neoadjuvant chemotherapy using epirubicin and cyclophosphamide followed by docetaxel and gemcitabine, plus trastuzumab if HER2-positive. The primary endpoint was the pathological complete response (pCR) rate in the breast in separate HER2-negative and HER2-positive cohorts. Secondary endpoints included pCR in both the breast and axillary lymph nodes, clinical and radiological response rates, disease free survival and safety. RESULTS 81 patients were enrolled: 63 HER2-negative and 18 HER2-positive. 67 (84%) completed all cycles of chemotherapy, and 78 (96%) proceeded to surgery. pCR was achieved by 12 (20%) patients with HER2-negative, and 9 (53%) with HER2-positive disease. At the first interim analysis, addition of prophylactic G-CSF was recommended due to excess neutropenia. The HER2-negative cohort was closed to accrual because it did not meet the pre-specified target for pCR, and the HER2-positive cohort was closed due to slow accrual. At a median follow-up of 24 months, 12 of 81 (15%) patients had experienced a relapse of their breast cancer. CONCLUSION Neoadjuvant gemcitabine, when added to docetaxel, after epirubicin and cyclophosphamide, did not reach the pre-specified expectations for pCR rate in HER2-negative tumours. Excess neutropenia was observed, requiring growth factor support. Addition of gemcitabine to docetaxel in this schedule cannot be recommended.

Abstract
There may be a relationship between the incidence of vasomotor and arthralgia/myalgia symptoms and treatment outcomes for postmenopausal breast cancer patients with endocrine-responsive disease who received adjuvant letrozole or tamoxifen. Data on patients randomized into the monotherapy arms of the BIG 1-98 clinical trial who did not have either vasomotor or arthralgia/myalgia/carpal tunnel (AMC) symptoms reported at baseline, started protocol treatment and were alive and disease-free at the 3-month landmark (n = 4,798) and at the 12-month landmark (n = 4,682) were used for this report. Cohorts of patients with vasomotor symptoms, AMC symptoms, neither, or both were defined at both 3 and 12 months from randomization. Landmark analyses were performed for disease-free survival (DFS) and for breast cancer free interval (BCFI), using regression analysis to estimate hazard ratios (HR) and 95 % confidence intervals (CI). Median follow-up was 7.0 years. Reporting of AMC symptoms was associated with better outcome for both the 3- and 12-month landmark analyses [e.g., 12-month landmark, HR (95 % CI) for DFS = 0.65 (0.49-0.87), and for BCFI = 0.70 (0.49-0.99)]. By contrast, reporting of vasomotor symptoms was less clearly associated with DFS [12-month DFS HR (95 % CI) = 0.82 (0.70-0.96)] and BCFI (12-month DFS HR (95 % CI) = 0.97 (0.80-1.18). Interaction tests indicated no effect of treatment group on associations between symptoms and outcomes. While reporting of AMC symptoms was clearly associated with better DFS and BCFI, the association between vasomotor symptoms and outcome was less clear, especially with respect to breast cancer-related events.
