Background: The aim of the study was to measure women’s decisions about breast reconstruction (BR) after mastectomy and to assess the factors contributing to their decisions, in a context involving shared decision-making and maximum patient autonomy.Methods: Women who were about to undergo mastectomy for primary breast cancer were systematically offered choices concerning BR and time of reconstruction (intervention always covered by the French National Insurance System). Self-administered questionnaires were used prior to the operation.Results: Among the 181 respondents, 81% opted for BR and 19% for mastectomy alone. In comparison with those who chose mastectomy alone, those opting for BR more frequently recognized the importance of discussing these matters with the surgeon and their partner (adjusted odds ratio [ORadj] = 13.45 and 3.59, respectively; P < .05) and realized that their body image was important (ORadj = 10.55, P < .01); fears about surgery prevented some of the women from opting for BR (ORadj = 0.688, P < .05). Among the women opting for BR, 83% chose immediate breast reconstruction (IBR) and 17% chose delayed breast reconstruction (DBR). The preference for IBR was mainly attributable to the fact that these women had benefited more frequently from doctor–patient discussions (ORadj = 3.49, P < .05) but was also attributable to the patients’ physical and functional characteristics: they were in a poorer state of health (P < .05). The surgeons predicted their patients’ preferences fairly accurately.Conclusions: In a context of maximum autonomy, the great majority of the women chose IBR. The patients’ choices were explained mainly by their psychosocial characteristics. The indication for BR should be properly discussed between patients and surgeons before mastectomy.

Despite the acceptance that health gain is the most important attribute of health care, other aspects of health care may affect utility. The aim of this paper is to report an experiment to test the impact of providing different levels of information in the context of the EuroWill study, a joint contingent valuation (CV) of multiple health programmes. Three hundred and three respondents were simultaneously asked for their willingness-to-pay (WTP) for three health care programmes: more heart operations, a new breast cancer treatment and a helicopter ambulance service. To test for the impact of variation in information, three versions of one of the programmes (heart) were provided. Results show that WTP for all three programmes tended to be significantly higher for respondents who were provided additional positive information about the heart programme. Our results show that CV of health care programmes, which only take into account medical outcomes, may lead to the value of such programmes not being adequately estimated, and that the impact of information may even be more decisive in the context of joint evaluation of multiple, rather than single, programmes.

Objectives. This study aimed to determine whether cancer patients report different information-seeking behaviors (ISBs), investigate why they searched for information, and determine the relationship between their ISBs and their socioeconomic and behavioral characteristics. The authors also explored the relationship between ISB and participation in the medical decision-making process as well as the patients’ health state. Methods. A sample of 4270 French cancer survivors aged 18 or older was interviewed at 2 years following diagnosis. Rather than deciding a priori who should be considered an information seeker, the authors chose to statistically define the different ISBs using cluster analysis. Results. The authors identified 4 distinct profiles: Stereotypical high-information seekers and acquainted seekers are generally highly educated. They search for information due to their own motivation or because they are close to the medical profession. Constrained information seekers are characterized by a low socioeconomic status. They perceive themselves as “dropouts” of the health care system. Finally, the general information seekers did not systematically resort to any specific ISB. The authors show that after adjustment, belonging to a specific ISB was associated with the likelihood of participating in the medical decision-making process and, more surprisingly, with health state. Conclusions. A key finding of this study is that social disparities are significantly associated with the different ISBs. If these relationships are found in other samples, it would further support the need for medical teams to pay more attention to patients with lower levels of education, particularly in health care systems that have acknowledged equality as a founding principle. The clusters determined in this study offer a potential theoretical framework that can be used in future studies.

Purpose:To assess the impact of BRCA1/2 test results on carriers’ reproductive decision-making and the factors determining their theoretical intentions about preimplantation genetic diagnosis (PGD) and prenatal diagnosis (PND).Methods:Unaffected BRCA1/2 mutation carriers of childbearing age (N = 605; 449 women; 151 men) were included at least 1 year after the disclosure of their test results in a cross-sectional survey nested in a national cohort. Multivariate adjustment was performed on the data obtained in self-administered questionnaires.Results:Response rate was 81.0%. Overall, 32.5% and 50% said that they would undergo PGD/PND, respectively, at a theoretical next pregnancy, whereas only 12.1% found termination of pregnancy (TOP) acceptable. Theoretical intentions toward PGD did not depend on gender/age, but were higher among those with no future childbearing plans (adjusted odds ratio (AOR) 95% confidence interval (CI): 3.5 (1.9–6.4)) and those having fewer relatives with cancer (AOR 1.5 95% CI (1.0–2.3)). Greater TOP acceptability was observed among males and those with lower educational levels; 85.4% of respondents agreed that information about PGD/PND should be systematically delivered with the test results.Conclusions:The closer to reproductive decision-making BRCA1/2 carriers are, i.e., when they are more likely to be making future reproductive plans, the less frequently they intend to have PGD. Carriers’ theoretical intentions toward PND are discussed further.Genet Med 2012:14(5):527–534

BACKGROUND Using data from the PACS 01 randomized trial, we evaluated the cost-effectiveness of anthracyclines plus docetaxel (Taxotere; FEC-D) versus anthracyclines alone (FEC100) in patients with node-positive breast cancer. PATIENTS AND METHODS Costs and outcomes were assessed in 1996 patients and the incremental cost-effectiveness ratios (ICERs) were estimated, using quality-adjusted life years (QALYs) as outcome. To deal with uncertainty due to sampling fluctuations, confidence regions around the ICERs were calculated and cost-effectiveness acceptability curves were drawn up. Sensitivity analyses were also carried out to assess the robustness of conclusions. RESULTS The mean cost of treatment was 33% higher with strategy FEC-D, but this difference decreased to 18% at a 5-year horizon. The ICER of FEC-D versus FEC100 was estimated to be 9665euro per QALY gained (95% confidence interval euro2372-euro55 515). The estimated probability that FEC-D was cost-effective reached >96% for a threshold of euro50 000 per QALY gained. If the price of taxane decreased slightly, the ICER would reach some very reasonable levels and this strategy would therefore be much more cost-effective. CONCLUSION The sequential use of FEC100 followed by docetaxel appears to be a cost-effective alternative, even when uncertainty is taken into account.

Governments across Europe are required to make decisions about how best to allocate scarce health care resources. There are legitimate arguments for eliciting societal vales in relation to health care resource allocation given the roles of the general public as payers and potential patients. However, relatively little is known about the views of the general public on general principles which could guide these decisions. In this paper we present five societal viewpoints on principles for health care resources allocation and develop a new approach, Q2S, designed to investigate the extent to which these views are held across a range of European countries. An online survey was developed, based on a previously completed study Q methodology, and delivered between November 2009 and February 2010 across nine countries to 33,515 respondents. The largest proportion of our respondents (44%), were found to most associate themselves with an egalitarian perspective. Differences in views were more strongly associated with countries than with socio-demographic characteristics. These results provide information which could be useful for decision makers in understanding the pluralistic context in which they are making health care resource allocation decisions and how different groups in society may respond to such decisions.

The aim of this study was to evaluate and to compare in terms of toxicity the modulations of dose intensity of cyclophosphamide and doxorubicin in adjuvant chemotherapy for high-risk breast cancer. Four cycles of sequential high-dose chemotherapy with doxorubicin and cyclophosphamide (AC), supported with G-CSF and peripheral blood stem cells (PBSC) were administered to 81 women. Three successive cohorts were studied: doxorubicin (75 mg/m2) + cyclophosphamide (3000 mg/m2) every 21 days (group 1), doxorubicin (75 mg/m2) + cyclophosphamide (3000 mg/m2) every 15 days (group 2), and doxorubicin (75 mg/m2) + cyclophosphamide (6000 mg/m2) every 21 days (group 3). Seventy-five patients received four cycles of treatment with a total of 310 cycles administered. The received dose intensity of doxorubicin was higher in group 2 and that of cyclophosphamide was lower in group 1 than in the other two groups. Hematological and extra-hematological toxicities, as well as the number and duration of hospitalizations for toxicity, were significantly higher in group 3. We conclude that the group 3 regimen is associated with toxicities comparable to autologous transplantation. Increasing dose intensity of doxorubicin and cyclophosphamide is feasible in an outpatient setting and safe in groups 1 and 2 with the support of hematopoietic factor and PBSC.

ABSTRACT The ANRS-IPERGAY trial consisted in providing sexual activity-based antiretroviral prophylaxis for HIV prevention (PrEP) with a package of prevention tools (counselling, condoms, HIV and sexually transmitted infections’ screening) to highly exposed HIV-negative men who have sex with men (MSM). Few data exist concerning the patient-physician relationship in the particular context of PrEP, where physicians discuss sexual behaviours with MSM who are not classic patients, in that consultation is for prevention purposes, not for illness. This study took place during the open-label extension of ANRS-IPERGAY trial when all participants received PrEP. In this qualitative study, we examined how physicians perceived their relationship with participants in the ANRS-IPERGAY trial. Of all 30 physicians involved in the trial who were contacted by email to participate in an interview about their opinions and perceptions of ANRS-IPERGAY 18 volunteered to participate in the current sub-study. We performed a vertical analysis for each interview to identify the extract in each physician’s discourse concerning their relationship with MSM participants, and conducted a horizontal analysis to construct the thematic tree and subsequently investigate differences and similitudes between themes. An analysis of all physicians’ discourses showed that the participant-physician relationship during the trial could be described through 4 themes: (i) personal experience of the relationship, (ii) trust and non-judgement, (iii) positive relational climate and (iv) influence of physician’s characteristics (age, gender, etc.) on relationship. We found that the particular context of PrEP led some physicians to adopt a patient-as-partner approach during consultations rather than a paternalist or hierarchical approach. Indeed, the close follow-up provided by the trial and the active role of patients in their own prevention care trajectory, are more compatible with the patient-as-partner approach. The prescription of PrEP may lead to an evolution in patient-physician relationships and may even modify the professional identity of physicians.

Context Despite huge advances in the fight against HIV concerning diagnosis, clinical efficacy of antiretroviral treatments (ART), patient survival and quality of life, there is still no cure. Recent developments in HIV cure research have opened the way for clinical trials which could lead to a temporary or definitive end to ART. However, ethical questions exist about related trial-participation risks. The main goal of the ANRS-APSEC survey was, using Q-methodology, to investigate the viewpoints of people living with HIV (PLWH) and HIV healthcare providers (HHP) regarding motivations for and barriers to participation in HIV Cure-related clinical trials (HCRCT). Materials and methods Thirty-three statements were defined encompassing seven dimensions: treatment and follow-up; risks; benefits; patient-physician relationship; beliefs and attitudes; information; target population. Forty-one PLWH and 41 HHP from five French HIV services were asked to rank-order the statements. Results Five main viewpoints were elicited from “the most motivated” to “the most reluctant” vis-à-vis HCRCT participation. All placed importance on the wish to participate in HIV research. This result is in line with the HIV-specific culture of joint mobilization. For some viewpoints, the motivation to participate in/propose HCRCT was primarily conditioned by side-effects and/or by constraints, which overall were more accepted by PLWH than HHP. Some viewpoints placed particular importance on HCRCT recruitment strategies. Finally, some expressed a high acceptance of risks and constraints but emphasized the need for information. Conclusion HIV cure research clinical trials (HCRCT) constitute a risky yet unavoidable step towards the goal of finding a cure. To improve future HCRCT and informed consent designs, based on PLWH and HHP preferences and expectations, we need greater knowledge about how these populations perceive the risks and the benefits of HCRCT. Our results confirmed the importance of careful, studied HCRCT design, management and communication, to ensure PLWH and HHP acceptability and convergence of their expectations.
