Self-perceptions of women after early breast cancer surgery

Surgery and health-related quality of life - A prospective follow up study on breast cancer patients in Finland

INTRODUCTION

The influence of different surgical approaches on breast cancer patients' Health-related Quality of life (HRQoL) is an important determinant when making decisions on the choice of treatment. Knowledge on how patients actually perceive different surgical treatments regarding long-term HRQoL is still scarce.

MATERIALS & METHODS

1065 patients with primary breast cancer operated on from 2008 to 2015 at Helsinki University Hospital, Finland were prospectively followed-up for two years. They filled in two HRQoL questionnaires, the EORTC QLQ C30 - BR 23 and the 15D, at baseline and at 3, 6, 12 and 24 months after surgery. Clinical data on treatments given and the course of recovery were collected from patient records. Patients were divided into four mutually exclusive groups according to surgical method: breast resection (n = 415), oncoplastic resection (n = 248), mastectomy (n = 351) and immediate reconstruction (n = 51). Clinical data were combined with HRQoL scores and analysed as multivariate modelling.

RESULTS

All groups experienced initially worsening overall HRQoL after baseline. Oncoplastic resection patients had the best body image and their HRQoL reached the highest level after treatments at 12 months whereas the reconstruction patients reached the highest HRQoL level first at 24 months. Mastectomy patients had the lowest scores throughout the 24-month follow-up.

CONCLUSION

Extensive surgery, in terms of immediate reconstruction, led to slower HRQoL recovery than oncoplastic techniques. Mastectomy patients are at risk of having the lowest HRQoL scores throughout their recovery after surgery.

The Impact of Patient Participation in Health Decisions Within Medical Encounters

Background: Although there are compelling moral arguments for patient participation in medical decisions, the link to health outcomes has not been systematically explored. Objective: Assess the extent to which patient participation in decision making within medical encounters is associated with measured patient outcomes. Methods: We conducted a primary search in PubMed—excluding non-English and animal studies—for articles on decision making in the context of the physician–patient relationship published through the end of February 2015, using the MeSH headings (Physician-Patient Relations [MeSH] OR Patient Participation [MeSH]) and the terms (decision OR decisions OR option OR options OR choice OR choices OR alternative OR alternatives) in the title or abstract. We also conducted a secondary search of references in all articles that met the inclusion criteria. Results: A thorough search process yielded 116 articles for final analysis. There was wide variation in study design, as well as measurement of patient participation and outcomes, among the studies. Eleven of the 116 studies were randomized controlled trials (RCTs). Interventions increased patient involvement in 10 (91%) of the 11 RCTs. At least one positive outcome was detected in 5 (50%) of the 10 RCTs reporting increased participation; the ratio of positive results among all outcome variables measured in these studies was much smaller. Although proportions differed, similar patterns were found across the 105 nonrandomized studies. Conclusions: Very few RCTs in the field have measures of participation in decision making and at least one health outcome. Moreover, extant studies exhibit little consistency in measurement of these variables, and results are mixed. There is a great need for well-designed, reproducible research on clinically relevant outcomes of patient participation in medical decisions.

A meta-analysis comparing breast conservation therapy alone to the oncoplastic technique

When immediate reconstruction is applied to breast conservation therapy (BCT), the benefits extend well beyond the minimization of poor cosmetic results. The purpose of this analysis was to compare literature outcomes between BCT alone and BCT with the oncoplastic approach.

METHODS

A meta-analysis was performed in PubMed using key words "oncoplastic," "partial breast reconstruction," and "breast conservation therapy." Case reports, series with less than 10 patients, and those with less than 1-year follow-up were excluded from the analysis. The 3 comparative groups included BCT with oncoplastic reduction techniques (Group A), BCT with oncoplastic flap techniques (Group B), and BCT alone (Group C).

RESULTS

Comparisons were made on 3165 patients in the BCT with oncoplastic group (Groups A and B, 41 papers) and 5494 patients in the BCT alone group (Group C, 20 papers). Demographics were similar, and tumor size was larger in the oncoplastic group (2.7 vs 1.2 cm). The weight of the lumpectomy specimen was 4 times larger in the oncoplastic group. The positive margin rate was significantly lower in the oncoplastic group (12% vs 21%, P < 0.0001). Reexcision was more common in the BCT alone group (14.6% vs 4%, P < 0.0001), however, completion mastectomy was more common in the oncoplastic group (6.5% vs 3.79%, P < 0.0001). The average follow-up was longer in the BCT alone group (64 vs 37 months). Local recurrence was 4% in the oncoplastic group and 7% in the BCT alone group. Satisfaction with the aesthetic outcome was significantly higher in the oncoplastic group (89.5% vs 82.9%, P < 0.001).

CONCLUSIONS

The oncoplastic approach to BCT allows a generous resection with subsequent reduction in positive margins. The true value on local recurrence remains to be determined. Patients are more satisfied with outcomes when the oncoplastic approach is used.

Expression of tenascin-C and its isoforms in the breast

Tenascin-C (TNC) is an extracellular matrix glycoprotein which is frequently up-regulated in a variety of pathological conditions including chronic inflammation and cancer. TNC has been implicated in the modulation of cell migration, proliferation, invasion and angiogenesis. Multiple isoforms of TNC can be generated through the alternative splicing of nine exons located in the fibronectin type III region of the molecule. The profile of isoforms expressed differs between cancers and normal breast, with the fully truncated TNC isoform being predominant in normal and benign tissues and higher molecular weight isoforms induced predominantly in cancer. The addition of extra domains within the fibronectin type III repeat domain greatly affects TNC function with multiple exon combinations available for splicing. Exons 14 and 16 are considered to be tumour-associated and have been shown to affect breast cell line invasion and growth in vitro to a greater extent than the full-length TNC isoform. This mini review will provide a summary of the literature to date regarding the expression of TNC isoforms in the breast and also discuss more recent developments in the field regarding exon AD1.

Satisfying patients' rights: a hospital patient survey

The aim of this project was to study the way in which patients' rights are being exercised in everyday hospital practice in Greece. Data were collected by using questionnaires and structured interviews with 600 patients. These patients were found to ignore the fact that special regulations exist regarding their rights. They considered their right to information was being respected, albeit to different degrees. Many patients allowed their doctors to make decisions. The right to confidentiality was not considered as a major priority by these patients because they doubted its applicability. They hesitated to protest when their rights were being violated. They thought that the most effective way of protecting their rights is either through the existence of someone with specialized knowledge or an internal hospital committee. These Greek patients appeared to be relatively satisfied with the way in which their rights were being exercised in hospital. However, a number of improvements could increase patient satisfaction regarding this issue.

Experiences and resources of breast cancer patients in short-stay surgery

Aimed at increasing the understanding and improving the quality of nursing care for breast cancer patients in short-stay surgery, this qualitative study set out to describe the experiences and, the intra- and extra-personal coping resources these patients. The data were collected among eight breast cancer patients (n = 8). On the whole the patients described short-stay surgery as a positive experience. They felt they had been discharged at the right time. The patients thought they had coped well and received valuable emotional, informational and instrumental support from health care personnel at each phase of the illness process. The breast cancer coordinator, in particular, served as a safety net for the patients. Informational support from health care personnel was considered adequate at the illness phase, but there was evidence of some lack of information at the care phase and current phase. Lack of knowledge about follow-up treatment was a major source of fear and anxiety for the patients. Later on, family members and friends served as important extra-personal coping resources, providing emotional and instrumental support. In addition, the patients' own intra-personal coping resources were essential during all the phases.

Quality of life and health status in breast carcinoma

Quality of life is of increasing importance in clinical oncology studies. When analysing publications concerning quality of life in breast cancer, however, the majority of the articles appear to study health status and not quality of life. Therefore five recommendations were formulated to apply reading a 'quality of life' article. With the use of these recommendations an article can be evaluated and the clinical significance can be assessed.

Do women newly diagnosed with breast cancer and consulting surgeon assess decision-making equally?

This study assesses the perception of the decision-making process of 25 surgeons and 194 patients (aged 21-81 years) who had newly diagnosed breast cancer and had to undergo mastectomy or breast-conserving surgery (BCS). The majority of women wanted to participate in decision-making. When it was medically possible to give a choice between BCS and mastectomy, only 59% of women received a choice. The main reason that 11% of the women went against surgeon's recommendations was fear of cancer recurrence. The most influential factors for women were the surgeon's recommendation, and fear of cancer recurrence. Medical assessment and the cosmetic result were the most influential factors for the surgeons. Female surgeons were more influenced by their assessment of the women's need for security, than male. In conclusion, not all women who are eligible for BCS receive an option. Women and surgeons emphasize influencing factors differently. The surgeon's gender was found to influence recommendation given.

A comparison of four treatment strategies for ductal carcinoma in situ using decision analysis

BACKGROUND

The goals of the current study were to compare four treatment approaches in the management of ductal carcinoma in situ (DCIS), to determine the conditions where mastectomy may be preferred to breast-conserving therapy (BCT), and to determine conditions where the addition of tamoxifen produces better results than BCT alone.

METHODS

A decision analysis model was used to compare four treatment approaches after local excision for DCIS: mastectomy, irradiation, irradiation plus adjuvant tamoxifen, or observation. The model weighed the potential benefits of each treatment approach (reduction of ipsilateral and/or contralateral breast carcinoma) against the potential risks of treatment-related toxicities. In addition, the model adjusted for the potential detrimental impact of local recurrence or treatment-related toxicity on health-related quality of life (HRQOL). Base-case estimates were obtained from published randomized trial data. One-way and two-way sensitivity analyses were performed.

RESULTS

According to the model, the optimal treatment for DCIS was strongly dependent on the individual's risk of local recurrence and the patient's attitudes toward mastectomy. Mastectomy was preferred in patients whose estimated 10-year risk of local recurrence was > 15%, provided that mastectomy resulted in a very low reduction in quality of life (i.e., utility estimate > 0.97). Conditions where the addition of tamoxifen was preferred to breast-conserving therapy alone included the following: estimated 10-year risk of local recurrence > 38%, estimated 10-year risk of developing a contralateral breast carcinoma > 6%, or a significant decrement in HRQOL associated with the development of an invasive local recurrence or salvage mastectomy (utility estimates < 0.85).

CONCLUSION

Based on this quality-adjusted model, BCT appeared to be the preferred treatment for DCIS. The most important determinants of optimal management for DCIS included the risk of local recurrence and the utility of mastectomy. Formal evaluation of utilities in the context of DCIS and more accurate determination of the risk of recurrence are required.

Outcome assessment in cancer management

The goals of cancer treatment may be prevention, cure, or palliation. In each case, the length and quality of survival are the ultimate outcomes to assess when evaluating the success of treatment. Some surrogate or intermediate endpoints, however, may be considered, such as toxicity or the tumor response. The first section of this article considers traditional outcomes and endpoints and intermediate or surrogate endpoints for survival and quality of life. The second section specifically addresses the issue of the quality-of-life outcome, which has become increasingly important over the last 2 decades. The last section suggests that combining survival and quality of life may not be easy. Costs are increasingly important in management of diseases, and the outcomes of cancer treatment frequently are measured against them. Although the definitions of cost-effectiveness and cost-utility are mentioned at the end of this article, the article does not deal with the problems of decision making for health resource allocation.
