Objective To determine how patients with breast cancer want their doctors to communicate with them. Design Qualitative study. Setting Breast unit and patients' homes. Participants 39 women with breast cancer. Main outcome measure Patients' reports of doctors' characteristics or behaviour that they valued or deprecated. Results Patients were not primarily concerned with doctors' communication skills. Instead they emphasised doctors' enduring characteristics. Specifically, they valued doctors whom they believed were technically expert, had formed individual relationships with them, and respected them. They therefore valued forms of communication that are currently not emphasised in training and research and did not intrinsically value others that are currently thought important, including provision of information and choice. Conclusions Women with breast cancer seek to regard their doctors as attachment figures who will care for them. They seek communication that does not compromise this view and that enhances confidence that they are cared for. Testing and elaborating our analysis will help to focus communication research and teaching on what patients need rather than on what professionals think they need.
BackgroundOestrogen receptor beta (ERβ) modulates ERα activity; wild type ERβ (ERβ1) and its splice variants may therefore impact on hormone responsiveness of breast cancer. ERβ2/ERβcx acts as a dominant negative inhibitor of ERα and expression of ERβ2 mRNA has been proposed as a candidate marker for outcome in primary breast cancer following adjuvant endocrine therapy. We therefore now assess ERβ2 protein by immunostaining and mRNA by quantitative RT-PCR in relation to treatment outcome.MethodsERβ2-specific immunostaining was quantified in 141 primary breast cancer cases receiving adjuvant endocrine therapy, but no neoadjuvant therapy or adjuvant chemotherapy. The expression of mRNA for ERβ2/ERβcx was measured in 100 cases by quantitative RT-PCR. Statistical analysis of breast cancer relapse and breast cancer survival was performed using Kaplan Meier log-rank tests and Cox's univariate and multivariate survival analysis.ResultsHigh ERβ2 immunostaining (Allred score >5) and high ERβ2 mRNA levels were independently associated with significantly better outcome across the whole cohort, including both ERα positive and negative cases (Log-Rank P < 0.05). However, only ERβ2 mRNA levels were significantly associated with better outcome in the ERα + subgroup (Log-Rank P = 0.01) and this was independent of grade, size, nodal status and progesterone receptor status (Cox hazard ratio 0.31 P = 0.02 for relapse; 0.17 P = 0.01 for survival). High ERβ2 mRNA was also associated with better outcome in node negative cases (Log Rank P < 0.001).ERβ2 protein levels were greater in ERα positive cases (T-test P = 0.00001), possibly explaining the association with better outcome. Levels of ERβ2 protein did not correlate ERβ2 mRNA levels, but 34% of cases had both high mRNA and protein and had a significantly better outcome (Log-Rank relapse P < 0.005).ConclusionHigh ERβ2 protein levels were associated with ERα expression. Although most cases with high ERβ2 mRNA had strong ERβ2 immunostaining, mRNA levels but not protein levels were independently predictive of outcome in tamoxifen-treated ERα + tumours. Post-transcriptional control needs to be considered when assessing the biological or clinical importance of ERβ proteins.
Current evidence for the value of ADMs in IBBR is limited. Use in practice should therefore be considered experimental, and evaluation within registries or well designed and conducted studies, ideally RCTs, is recommended to prevent widespread adoption of a potentially inferior intervention.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
