The development and initial evaluation of the Diarrhoea Management Diary (DMD) in patients with metastatic breast cancer.

PURPOSE: Chemotherapy-induced diarrhoea (CID) is a common, but often underreported problem in patients with breast cancer that has a profound effect on quality of life. It is best measured from a patient's perspective, but tools are limited. The aim of this study was to develop and evaluate the Diarrhoea Management Diary (DMD), a self-report measure to assess CID, use of self-management strategies and treatment adherence. METHODS: The DMD was constructed using an iterative process of instrument development: concept elicitation (literature review), item generation and reduction (cognitive debriefing), and pilot testing in the target population. After translation into eight languages, the DMD was used in an international randomised trial for women receiving lapatinib and capecitabine for metastatic breast cancer with or without prophylactic octreotide. Patterns of missing data and sensitivity to change were examined. RESULTS: The understandability and completeness of the 8-item DMD was confirmed in cognitive interviews and pilot testing. Practicability of the DMD was evaluated in 62 women with metastatic breast cancer (median age 57). Up to 68% reported CID at any given time-point, and 19% had diarrhoea at each time-point. Patients also described efficacy of different strategies for diarrhoea management. Missing data were associated with study discontinuation. DMD missing item response was 0.9%. Sensitivity to change was good at most assessment points. CONCLUSIONS: Although further psychometric testing is recommended, initial evaluation of the DMD showed good content validity and practicability in international research with cancer patients.

Adjuvant chemotherapy in elderly women with breast cancer: patients' perspectives on information giving and decision making.

BACKGROUND: Decisions about adjuvant chemotherapy in older women with early stage breast cancer (EBC) are often challenging. Uncertainty about benefits due to limited data about treatment efficacy and outcomes complicates decision making. This qualitative study explored older patients' experiences and preferences towards information giving and ultimate decisions about adjuvant chemotherapy. METHODS: Clinicians from 24 UK breast cancer teams reported on adjuvant chemotherapy decisions for women aged ≥70 years with EBC from April 2010 to December 2011. Women who were offered chemotherapy were invited to participate in structured interviews. Self-reported quality of life (QoL) and functional ability were assessed. Qualitative methods were used to identify themes associated with information giving and decision making. RESULTS: A total of 58/95 eligible women (61%) participated. Median age was 73 years (range 70-83). Mean total scores for QoL and functional ability were average. The majority of women preferred to make their treatment decisions collaboratively with a clinician (59%) or on their own (19%). The main reasons influencing decisions to accept chemotherapy were categorised as prevention of recurrence and clinician recommendation. Side effects, length of treatment, impact on QoL, low survival benefits and clinician recommendation influenced decisions to decline chemotherapy. The majority (80%) were satisfied with information provision, the communication with their clinician and explanation of treatment. CONCLUSIONS: Older women with EBC preferred to be involved in clinical decision making. Clinician recommendation plays a significant role in either accepting or declining chemotherapy. Well-informed decision making and effective communication between clinicians, older women and their family members are therefore important.

Pain and health-related quality of life in patients with advanced solid tumours and bone metastases: integrated results from three randomized, double-blind studies of denosumab and zoledronic acid.

PURPOSE: This analysis evaluated patient-reported outcomes and analgesic use in patients with bone metastases from solid tumours across three comparative studies of denosumab and zoledronic acid. METHODS: Pooled data were analysed from three identically designed double-blind phase III studies comparing subcutaneous denosumab 120 mg with intravenous zoledronic acid 4 mg monthly in patients with bone metastases from breast cancer (n = 2,046), castration-resistant prostate cancer (n = 1,901) or other solid tumours (n = 1,597). Pain severity, pain interference, health-related quality of life and analgesic use were quantified. RESULTS: At baseline, approximately half of patients had no/mild pain (53 % [1,386/2,620] denosumab; 50 % [1,297/2,578] zoledronic acid). Denosumab delayed onset of moderate/severe pain by 1.8 months (median, 6.5 vs 4.7 months; hazard ratio, 0.83; 95 % CI, 0.76-0.92; p < 0.001; 17 % risk reduction) and clinically meaningful increases in overall pain interference by 2.6 months (median, 10.3 vs 7.7 months; hazard ratio, 0.83; 95 % CI, 0.75-0.92; p < 0.001; 17 % risk reduction) compared with zoledronic acid. Strong opioid use and worsening of health-related quality of life were less common with denosumab. CONCLUSIONS: Across three large studies of patients with advanced solid tumours and bone metastases, denosumab prevented progression of pain severity and pain interference more effectively than zoledronic acid.

Evaluation of an educational program to improve communication with patients about early-phase trial participation.

BACKGROUND: Discussing early-phase cancer trials is challenging; most offer little personal benefit to patients with life-limiting illnesses who frequently have a poor understanding of and misconceptions about the therapeutic aims. We evaluated an evidence-based training program aimed at enhancing communication. METHODS: Prior to and after the intervention, 47 health care professionals (HCPs) experienced in early-phase trial recruitment were audio taped discussing trials with patient simulators who completed postinterview evaluations. Coders rated the interviews for the presence of information areas required to elicit ethical consent. HCPs reported their self-confidence on 15 different aspects of trial discussion. RESULTS: Significant objective and subjective improvements in communication were found after the workshop. Analyses of audio tapes showed positive shifts in: establishing the patient's knowledge of their prognosis (odds ratio [OR], 2.7; p = .002), discussing symptomatic care (OR, 3.8; p < .001), the aims of the trial (OR, 2.6; p =.002), and the unlikelihood of medical benefit (OR, 3.0; p = .021). Patient simulator ratings showed improvements in: the awareness of palliative care and symptom control (OR, 2.1; p = .004), the voluntariness of participation (OR, 3.7; p = .015), the opportunity to ask questions (OR, 2.9; p = .044), and the time to consider participation (OR, 6.1; p = .009). HCPs' self-confidence increased significantly for all 15 items (OR range, 1.5-2.9; p ≤ .001). CONCLUSION: This short, intensive workshop changed communication skills competency and self-efficacy in ways likely to promote valid, ethically informed consent from patients contemplating trial entry.

Patient-reported outcome instruments used to assess pain and functioning in studies of bisphosphonate treatment for bone metastases.

PURPOSE: When treating metastatic bone disease, relief of bone pain is often a key outcome. Because pain cannot be quantified with objective clinical measures, patient-reported outcome (PRO) measures are required to assess patients' subjective experience. The goal of the current review was to examine measures used to assess pain, as well as the impact of pain on functional status and health-related quality of life (HRQL), in trials of bisphosphonates for the treatment of bone metastases. METHODS: A literature search focused on articles published from January 1999 to April 2009. RESULTS: A total of 49 articles were located that used PROs to assess pain-related outcomes of bisphosphonate treatment for bone metastases. The Brief Pain Inventory was the most commonly used multi-item instrument. However, the most common approach for assessing pain was to administer a single-item scale such as a visual analog scale, numerical rating scale, or verbal rating scale. Of the 49 studies, 19 included a PRO assessing functional status or HRQL. CONCLUSIONS: Although pain is an important outcome of trials examining treatment for bone metastases, the current review suggests that there is little consistency in PRO measurement across studies. Furthermore, presentation of measures often lacked clear description, information on measurement properties, citations, clarity regarding method of administration, and consistent instrument names. Recommendations are provided for instrument validation within the target population, assessment of content validity, use of PRO instruments recently developed for patients with bone metastases, clear description of instruments, and implementation of measures consistent with recommendations from instrument developers.

Anastrozole and letrozole: an investigation and comparison of quality of life and tolerability.

Previous studies have demonstrated that both anastrozole and letrozole are well tolerated. Letrozole suppresses estrogen to a greater degree than anastrozole in the serum and breast tumor. Concerns have been raised that greater potency may adversely affect patients' quality of life (QOL). One hundred eighty-one postmenopausal women with invasive estrogen receptor-positive breast cancers were randomized to receive either 12 weeks of letrozole followed by 12 weeks of anastrozole or the reverse sequence. One hundred and six received immediate adjuvant aromatase inhibitors (AIs) following surgery, and 75 received extended adjuvant therapy. The Functional Assessment of Cancer Therapy Endocrine Subscale (FACT-B-ES) QOL questionnaires were completed to assess QOL on each drug. Additional side-effect profiles were collected. Each patient completed a patient preference form. Twenty-one patients withdrew before study end, 10/179 (5.6%) while taking letrozole and 4/173 (2.3%) while taking anastrozole (P = 0.12). Tamoxifen-naïve patients had a higher mean ES (endocrine symptoms subscale) score at entry versus those having extended therapy (66.0 vs. 61.9; P = 0.001). There was no significant change in FACT-B-ES (overall) scores or ES scores while patients were taking anastrozole or letrozole and no significant differences between drugs. Nearly 80% of patients reported one or more side effects with either agent. No differences in frequency, grade, or range of side effects were seen between drugs. Of 160 patients, 49 (30.6%) preferred letrozole, 57 (35.6%) preferred anastrozole, and 54 (33.8%) had no preference (P = 0.26, Pearson's Chi-squared test). In conclusion, both AIs are equally well tolerated. There were no significant differences in QOL scores between the two drugs.

Endocrine Treatment and Targeted Therapy for Hormone Receptor-Positive, Human Epidermal Growth Factor Receptor 2-Negative Metastatic Breast Cancer: ASCO Guideline Update.

PURPOSE: To update recommendations of the ASCO systemic therapy for hormone receptor (HR)-positive metastatic breast cancer (MBC) guideline. METHODS: An Expert Panel conducted a systematic review to identify new, potentially practice-changing data. RESULTS: Fifty-one articles met eligibility criteria and form the evidentiary basis for the recommendations. RECOMMENDATIONS: Alpelisib in combination with endocrine therapy (ET) should be offered to postmenopausal patients, and to male patients, with HR-positive, human epidermal growth factor receptor 2 (HER2)-negative, PIK3CA-mutated, ABC, or MBC following prior endocrine therapy with or without a cyclin-dependent kinase (CDK) 4/6 inhibitor. Clinicians should use next-generation sequencing in tumor tissue or cell-free DNA in plasma to detect PIK3CA mutations. If no mutation is found in cell-free DNA, testing in tumor tissue, if available, should be used as this will detect a small number of additional patients with PIK3CA mutations. There are insufficient data at present to recommend routine testing for ESR1 mutations to guide therapy for HR-positive, HER2-negative MBC. For BRCA1 or BRCA2 mutation carriers with metastatic HER2-negative breast cancer, olaparib or talazoparib should be offered in the 1st-line through 3rd-line setting. A nonsteroidal aromatase inhibitor (AI) and a CDK4/6 inhibitor should be offered to postmenopausal women with treatment-naïve HR-positive MBC. Fulvestrant and a CDK4/6 inhibitor should be offered to patients with progressive disease during treatment with AIs (or who develop a recurrence within 1 year of adjuvant AI therapy) with or without one line of prior chemotherapy for metastatic disease, or as first-line therapy. Treatment should be limited to those without prior exposure to CDK4/6 inhibitors in the metastatic setting.Additional information can be found at www.asco.org/breast-cancer-guidelines.

A Rasch and confirmatory factor analysis of the general health questionnaire (GHQ)--12.

BACKGROUND: The General Health Questionnaire (GHQ) - 12 was designed as a short questionnaire to assess psychiatric morbidity. Despite the fact that studies have suggested a number of competing multidimensional factor structures, it continues to be largely used as a unidimensional instrument. This may have an impact on the identification of psychiatric morbidity in target populations. The aim of this study was to explore the dimensionality of the GHQ-12 and to evaluate a number of alternative models for the instrument. METHODS: The data were drawn from a large heterogeneous sample of cancer patients. The Partial Credit Model (Rasch) was applied to the 12-item GHQ. Item misfit (infit mean square >or= 1.3) was identified, misfitting items removed and unidimensionality and differential item functioning (age, gender, and treatment aims) were assessed. The factor structures of the various alternative models proposed in the literature were explored and optimum model fit evaluated using Confirmatory Factor Analysis. RESULTS: The Rasch analysis of the 12-item GHQ identified six misfitting items. Removal of these items produced a six-item instrument which was not unidimensional. The Rasch analysis of an 8-item GHQ demonstrated two unidimensional structures corresponding to Anxiety/Depression and Social Dysfunction. No significant differential item functioning was observed by age, gender and treatment aims for the six- and eight-item GHQ. Two models competed for best fit from the confirmatory factor analysis, namely the GHQ-8 and Hankin's (2008) unidimensional model, however, the GHQ-8 produced the best overall fit statistics. CONCLUSIONS: The results are consistent with the evidence that the GHQ-12 is a multi-dimensional instrument. Use of the summated scores for the GHQ-12 could potentially lead to an incorrect assessment of patients' psychiatric morbidity. Further evaluation of the GHQ-12 with different target populations is warranted.

Communication and informed consent in phase 1 trials: a review of the literature from January 2005 to July 2009.

OBJECTIVE AND METHODS: A review conducted in 2005 identified many of the communication difficulties experienced by patients and doctors when discussing phase 1 (P1) oncology trials. The current paper is an update of the area and focuses on studies that measure patient comprehension of information given during the P1 trial discussion and ways to enhance understanding. A literature search was performed for relevant articles published between January 2005 and July 1st 2009. RESULTS: Only 12/109 studies met the criteria for inclusion in the review. One study recorded the actual trial discussion and compared patients' understanding with what the clinician had communicated. The others used interview techniques and surveys to elicit patients' understanding of P1 trials, motivations for considering trials and expectations of benefit. Two examined interventions to aid patient understanding. CONCLUSION: Explaining potential participation in a P1 trial with a patient with cancer is not an easy task: the doctor must ensure that the patient has an accurate understanding of their condition and that standard treatments have now been exhausted. This must be followed by admission of the probable lack of any therapeutic benefit from the P1 drug together with the possibility that there might be unwanted side effects, many of which are unknown. These are all challenging subjects. New educational initiatives informed through research conducted with patients and health care professionals are currently being developed and clearly much needed.

Effects of anastrozole on cognitive performance in postmenopausal women: a randomised, double-blind chemoprevention trial (IBIS II).

BACKGROUND: Mild cognitive impairments have been recorded in cross-sectional studies of women with breast cancer receiving endocrine treatment. More comprehensive studies were warranted because aromatase inhibitors are being used increasingly in both chemoprevention and adjuvant settings. We report findings from the cognitive subprotocol of the International Breast Intervention Study (IBIS II), a double-blind placebo-controlled trial of anastrozole in postmenopausal women at high risk of developing breast cancer. We aimed to study and compare the effect of anastrozole versus placebo on memory and attention in these women. METHODS: Between Jan 3, 2003, and Dec 21, 2005, participants were recruited into the cognitive subprotocol from five UK centres. Cognitive assessments were done before randomisation, at 6 months, and at 24 months. 227 of 249 women approached completed a comprehensive set of standardised cognitive tasks at baseline and were randomly assigned to receive anastrozole (1 mg/day for 5 years) or placebo. Psychological morbidity, endocrine symptoms, and self-reported cognitive complaints were also measured. The main outcomes were cognitive task scores at baseline, 6 months, and 24 months. Analyses were done by intention to treat. This study is registered as an International Standard Randomised Controlled Trial, number ISRCTN31488319. FINDINGS: 111 women were assigned to anastrozole and 116 women to placebo. At 6 months, ten women in each group were excluded from analysis, leaving a total of 207 of 227 (91%) women available for further assessments. At 24 months, 24 women were excluded from the anastrozole group and 32 from the placebo group, leaving 151 of 227 (67%) women. We did not note any significant differences between the groups for any of the cognitive tasks. By 6 months, 13 women in both groups reported changes to their memory and this had decreased to five women in the placebo group and three women in the anastrozole group by the 24-month assessment. Significantly more women in the anastrozole group complained of hot flushes at 24 months (23 of 76 [30%] vs 11 of 73 [15%], p=0.032, not corrected for multiple comparison), but this was the only difference in reported endocrine symptoms. INTERPRETATION: These findings show little or no impairment of cognitive performance with the use of anastrozole compared with placebo in postmenopausal women at high risk of developing breast cancer who were able to tolerate endocrine-related side-effects. Future studies assessing cognition should be done within randomised trials with baseline assessments to ascertain the true extent of the putative effects that treatments for breast cancer might have on memory and attention.

Sexual functioning in 4,418 postmenopausal women participating in UKCTOCS: a qualitative free-text analysis.

OBJECTIVE: Sexual well-being can contribute significantly to the overall quality of women's lives. This qualitative study aimed to examine sexual activity, functioning, and satisfaction in a large sample of postmenopausal women from the UK Collaborative Trial of Ovarian Cancer Screening (UKCTOCS) METHODS:: Thematic analysis was used to evaluate the free-text data of the Fallowfield Sexual Activity Questionnaire (FSAQ) completed by UKCTOCS participants at baseline before annual screening. RESULTS: A total of 24,305 women completed the baseline FSAQ and 4,525 (19%) provided free-text data, with 4,418 comments eligible for analysis. Median age was 64 years; 65% had a partner and 22.5% were sexually active. Four interrelated themes were derived: partner availability, physical and sexual health, mental well-being, and interpersonal relationships. Primary reason for absence of sexual activity was lack of a partner, mainly due to widowhood (n = 1,000). Women discussed how partner's medical condition (27%) or sexual dysfunction (13.5%), their own physical health (18%) or menopause-related symptoms (12.5%), and prescribed medication (7%) affected sexual activity. Impact of low libido in self (16%) or partner (7%), relationship problems (10.5%) or logistics (6%), and perceptions of ageing (9%) were also mentioned. Few (3%) referred to positive sexual experiences or had sought medical help for sexual problems (6%). CONCLUSIONS: This qualitative analysis explored postmenopausal women's perspective on their sexual functioning. Having an intimate partner and good physical health are key factors for continuation of sexual activity and satisfaction. Further sexual education for healthcare professionals is needed to raise awareness about sexuality and sexual difficulties in later life. : Video Summary: Supplemental Digital Content 1, http://links.lww.com/MENO/A426.

Recognition and management of treatment-related side effects for breast cancer patients receiving adjuvant endocrine therapy.

In postmenopausal women with hormone receptor-positive early-stage breast cancer, the use of aromatase inhibitors (AIs) to suppress estrogen is associated with improved clinical outcomes compared with tamoxifen therapy. Women receiving such endocrine therapy may experience treatment-related side effects that negatively affect health-related quality of life (QoL) and adherence to therapy. In published clinical trials and in clinical practice, adverse events (AEs) constitute the main reason for nonadherence to endocrine treatment. Serious AEs are sometimes resolved by switching to a different agent, whereas other side effects can often be managed to allow patients to remain on therapy without sacrificing QoL. Across all adjuvant endocrine trials, regardless of the treatment received, vasomotor symptoms such as hot flashes are the most common side effects. Other frequently reported side effects, such as vaginal discharge, vaginal dryness, dyspareunia, and arthralgia, vary in prevalence between tamoxifen and AIs. Here we provide an overview of reported AEs of adjuvant endocrine therapy, focusing on those that are amenable to pharmacologic or nonpharmacologic management without treatment discontinuation. Also highlighted are specific management strategies that may improve patient QoL and thereby optimize adherence to therapy, which in turn might improve patient outcomes.

Rasch fit statistics and sample size considerations for polytomous data.

BACKGROUND: Previous research on educational data has demonstrated that Rasch fit statistics (mean squares and t-statistics) are highly susceptible to sample size variation for dichotomously scored rating data, although little is known about this relationship for polytomous data. These statistics help inform researchers about how well items fit to a unidimensional latent trait, and are an important adjunct to modern psychometrics. Given the increasing use of Rasch models in health research the purpose of this study was therefore to explore the relationship between fit statistics and sample size for polytomous data. METHODS: Data were collated from a heterogeneous sample of cancer patients (n = 4072) who had completed both the Patient Health Questionnaire - 9 and the Hospital Anxiety and Depression Scale. Ten samples were drawn with replacement for each of eight sample sizes (n = 25 to n = 3200). The Rating and Partial Credit Models were applied and the mean square and t-fit statistics (infit/outfit) derived for each model. RESULTS: The results demonstrated that t-statistics were highly sensitive to sample size, whereas mean square statistics remained relatively stable for polytomous data. CONCLUSION: It was concluded that mean square statistics were relatively independent of sample size for polytomous data and that misfit to the model could be identified using published recommended ranges.

A randomized trial of exemestane after two to three years of tamoxifen therapy in postmenopausal women with primary breast cancer.

BACKGROUND: Tamoxifen, taken for five years, is the standard adjuvant treatment for postmenopausal women with primary, estrogen-receptor-positive breast cancer. Despite this treatment, however, some patients have a relapse. METHODS: We conducted a double-blind, randomized trial to test whether, after two to three years of tamoxifen therapy, switching to exemestane was more effective than continuing tamoxifen therapy for the remainder of the five years of treatment. The primary end point was disease-free survival. RESULTS: Of the 4742 patients enrolled, 2362 were randomly assigned to switch to exemestane, and 2380 to continue to receive tamoxifen. After a median follow-up of 30.6 months, 449 first events (local or metastatic recurrence, contralateral breast cancer, or death) were reported--183 in the exemestane group and 266 in the tamoxifen group. The unadjusted hazard ratio in the exemestane group as compared with the tamoxifen group was 0.68 (95 percent confidence interval, 0.56 to 0.82; P<0.001 by the log-rank test), representing a 32 percent reduction in risk and corresponding to an absolute benefit in terms of disease-free survival of 4.7 percent (95 percent confidence interval, 2.6 to 6.8) at three years after randomization. Overall survival was not significantly different in the two groups, with 93 deaths occurring in the exemestane group and 106 in the tamoxifen group. Severe toxic effects of exemestane were rare. Contralateral breast cancer occurred in 20 patients in the tamoxifen group and 9 in the exemestane group (P=0.04). CONCLUSIONS: Exemestane therapy after two to three years of tamoxifen therapy significantly improved disease-free survival as compared with the standard five years of tamoxifen treatment.

After going through chemotherapy I can't see another needle.

Needle anxiety not only impacts on a patient's quality of life but can delay or prevent future medical care. Our survey of women with breast cancer indicated that 78/208 women (37.5%) reported feeling anxious about injections. Patients who reported needle anxiety were significantly younger (t(206)=3.72; P<0.01), with a lower body mass index (BMI) (t(182)=2.16; P<0.05), experience of chemotherapy (chi(2)(1)=8.29; P<0.01), a lower internal health locus of control (t(187)=2.28; P<0.05) and higher levels of state (t(197)=-3.58; P<0.01) and trait anxiety (t(197)=-2.30; P<0.05). Patients repeatedly highlighted the experience of chemotherapy as having caused their needle anxiety. Patient discourse suggests that chemotherapy related needle anxiety is a result of physical (e.g. finding a suitable vein) and environmental (e.g. the chemotherapy room) factors. Patients with cancer require psychosocial support during all stages of care, this should include the application of techniques to prevent or ameliorate the development of anxiety caused by certain aspects of cancer treatments, such as the development of chemotherapy-related needle anxiety.

Health-related quality of life in patients undergoing drug therapy for advanced non-small-cell lung cancer.

Health-related quality of life (HRQoL) is increasingly recognized as an important outcome in the treatment of advanced non-small-cell lung cancer (NSCLC). This article reviews HRQoL data from a literature search that identified 32 randomized trials of conventional chemotherapy in patients with advanced NSCLC. In common with much of the research in this area, interpretation of the data from some trials was limited by weaknesses in data collection and reporting of HRQoL results. Nevertheless, the trials comparing chemotherapy with best supportive care consistently identified that some components of HRQoL improved with chemotherapy, despite the associated toxicity of many of the regimens used. Novel targeted therapies promise efficacy without the toxicity typically observed with conventional chemotherapy, and this article also reviews HRQoL data from trials of gefitinib (IRESSA), the first epidermal growth factor receptor tyrosine kinase inhibitor to have demonstrated prospectively defined, clinically meaningful improvements in disease-related symptoms and HRQoL in patients with advanced NSCLC. In all trials reviewed, HRQoL findings to date support the incorporation of well-validated measures of HRQoL and symptom improvement in all future trials of drug therapy in advanced NSCLC patients. Ideally, the trials should have a prospectively defined HRQoL hypothesis, include measures to improve compliance with HRQoL assessments, and address the clinical meaning of the HRQoL findings.

For the Benefit of Others: Reasons Why Women with Breast Cancer Participate in RCTs.

BACKGROUND: Appreciation of the barriers and drivers affecting enrolment in randomised clinical trials (RCTs) is important for future trial design, communication and information provision. METHODS: As part of an intervention to facilitate UK multidisciplinary team communication about RCTs, women with breast cancer who discussed trials with doctors or research nurses completed questionnaires examining i) clarity of trial information and ii) reasons for their trial decision. RESULTS: 152 women completed the questionnaires; 113/152 (74%) consented to RCT enrolment. Patients' satisfaction with communication about the trial information was very good, irrespective of participation decisions. Acceptors' and decliners' responses to 9/16 statements concerning decisions about trial participation differed significantly. 'Wanting to help with doctor's research' influenced 100% acceptors compared to 57% of decliners (p < 0.001). Decliners were more likely to be 'worried about randomisation' (20 vs. 39%; p < 0.035) and to 'want doctor to choose treatment rather than be randomised' (31 vs. 53%; p < 0.031). Primary reason for trial acceptance was altruism; 'I feel that others with my illness will benefit from the results of the trial', 58/108 (54%). CONCLUSION: A majority of women accepted RCT entry citing altruistic motivations as the primary driver for participation. Trial design and setting (metastatic or adjuvant) had little impact on participation.

Implementing the UK Medical Research Council (MRC) RT01 trial (ISRCTN 47772397): methods and practicalities of a randomised controlled trial of conformal radiotherapy in men with localised prostate cancer.

BACKGROUND AND PURPOSE: Radiotherapy is the most frequently used treatment for men with localised prostate cancer. Conformal radiotherapy (CFRT) is a relatively new development. MRC RT01 was set-up to explore optimum CFRT dose. PATIENTS AND METHODS: RT01 was an international multi-centre randomised controlled trial for men with T1b-T3a, N0, M0 prostate cancer that evolved from a single-centre pilot trial of similar design. All men received at least 3 months of pre-radiotherapy hormone treatment, before randomisation to standard (64 Gy) or high dose (74 Gy) radical CFRT. Accrual was completed in December 2001 with 843 men randomised from 25 centres in less than 4 years. RT01 has been a catalyst for implementing CFRT across UK. In addition to the Trial Management Group, independent Data Monitoring and Ethics Committee and independent Trial Steering Committee, a Quality of Life and Health Economics (QL/HE) group, a radiotherapy Quality Assurance (QA) Group and a Radiography Trial Implementation Group were set up. The QL/HE group ensured implementation, compliance, analysis and interpretation of the QL and HE data in the trial. The inauguration of QA and Radiography groups facilitated inter-centre collaboration. The QA Group ensured procedures were in place before and during trial participation, and monitored quality and consistency with systems including a physics questionnaire, a clinical examples exercise, a standard operating procedure document, designing and building a phantom, and convening a complications modelling subgroup. The Radiography group agreed and implemented technique improvements. RESULTS: More centres participated than initially predicted, enabling recruitment better than scheduled. The trial expedited the implementation of CFRT in many UK radiotherapy centres. Additionally, the QA and Radiography groups helped ensure smooth initiation and established consistency in planning, dosimetry and delivery of prostate CFRT services at participating UK centres. Considerable data has been collected; a series of papers will be produced, although mature clinical trial results are not anticipated until 2006-2008.

Evolution of breast cancer treatments: current options and quality-of-life considerations.

Data from patient self-report questionnaires provide valuable information about side effects that patients may view as having a significantly detrimental impact on their quality of life and yet are not always recognised as important by healthcare professionals. Such information is very important in enabling patients to make informed choices regarding treatment options. Despite this, formal data collection from patient self-report assessments still fails to influence management decisions as much as traditional outcome measures such as disease-free survival, or clinician-recorded symptoms. There are now a number of different options for the treatment of patients with breast cancer. These include antioestrogens, aromatase inhibitors and oestrogen receptor antagonists for postmenopausal women, and chemotherapy and ovarian ablation (via oophorectomy, irradiation or with luteinising hormone-releasing hormone agonists) for premenopausal women. However, there are still surprisingly few published reports from comprehensive quality-of-life studies comparing such treatments and thus little is known about the relative impacts of each of these on quality of life. Here, the evolution of hormonal therapies for breast cancer is reviewed and the differences between the tolerability profiles of currently available treatment options are highlighted.
