Abstract

:
Breast Cancer (BC) is the leading cause of death due to cancer in women. Ensuring equitable, quality-assured and effective care has increased the complexity of BC management. This systematic review reports on the state-of-the art of available literature investigating the enactment of personalized treatment and patient-centered care models in BC clinical practice, building a framework for the delivery of personalized BC care within a Patient-Centered model. Databases were searched for articles (from the inception to December 2020) reporting on Patient-Centered or Personalized Medicine BC management models, assessing success factors or limits. Out of 1885 records, 25 studies were included in our analysis. The main success factors include clearly defined roles and responsibilities within a multi-professional collaboration, appropriate training programs and adequate communication strategies and adopting a universal genomic language to improve patients’ involvement in the decision-making process. Among detected barriers, delays in the use of genetic testing were linked to the lack of public reimbursement schemes and of clear indications in timing and appropriateness. Overall, both care approaches are complementary and necessary to effectively improve BC patient management. Our framework attempts to bridge the gap in assigning a central role played by shared decision-making, still scarcely investigated in literature.

1. Introduction

Among today’s major public health concerns, female Breast Cancer (BC) is responsible for an estimated 2.3 million new cases every year, surpassing lung cancer as the most commonly diagnosed cancer (11.7% of all cases) and leading cause of death due to cancer in women [1]. Efforts towards guaranteeing standardized, quality-assured and effective care have led to an increasing complexity and specialization of BC management, inevitably backed by an integration of multi-specialist inputs provided collaboratively through the efforts of several healthcare practitioners. Multidisciplinary care in BC, represented by the Breast Unit model, has become the gold-standard of patient-centered BC care and has been included among the determinants for accreditation and funding of facilities, given its capacity to improve patients’ quality of life and survival rates [2,3,4].
Complementarily, advances in diagnosis and treatment have equipped clinical practice with ensembles of newly developed targeted therapies [5] and personalized medicine techniques that are gradually improving outcomes and survival, as recent research is equipping specialists with a broader understanding of the biology and heterogeneity of BC, of mechanisms behind tumour resistance and with the possibility of predicting patients’ responses to therapies, especially when dedicated clinical governance tools (i.e., molecular tumour boards) are instituted within the care pathway.
Despite such documented progress, literature seems to highlight that the application of such innovations into routine clinical practice is proceeding at a slower pace compared to the generation of such findings [6], stressing the need to concentrate efforts on their implementation into real-life settings.
The aim of this systematic review is two-fold. First, to report on the state-of-the art of available literature investigating the enactment of personalized treatment and patient-centered care models in BC clinical practice. Second, to propose a comprehensive care management framework for the delivery of personalized care to patients with BC, within a patient-centered care model.

2. Materials and Methods

This systematic review was conducted and reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement [7].

2.1. Search Strategy

The electronic databases of Web of Science, PubMed, Scopus were searched to retrieve potential eligible articles, published in English from the inception to December 2020. A Boolean search string was created using the elements of the PICO model (P, population/patient; I, intervention/indicator; C, comparator/control; and O, outcome).
Furthermore, the search on Scopus was restricted to only humans, English language, “medicine” subject area, document types—articles, reviews, editorials, letters—and publication stage—final articles. Keywords such as “breast cancer management”; “breast units”; “personalized medicine”; “patient centeredness”; “patient-centered care”; “multidisciplinary team”; “tumor board”; “molecular tumor board”; “success factors”; “limits”; “cost effectiveness” were used.

2.2. Inclusion/Exclusion Criteria

Articles reporting breast cancer management in terms of patient-centered care and personalized medicine approaches were considered eligible. Studies mainly discussing breast cancer clinical therapeutics, clinical epidemiological data or surgical data were excluded.
For the purpose of our study, we used the European Commission definition, according to which “Personalized medicine” is “A medical model using characterization of individuals’ phenotypes and genotypes (e.g., molecular profiling, medical imaging, lifestyle data) for tailoring the right therapeutic strategy for the right person at the right time, and/or to determine the predisposition to disease and/or to deliver timely and targeted prevention” [8].
Similarly, we used the IOM (Institute of Medicine) definition of Patient-Centered care as “care that is respectful of and responsive to individual patient preferences, needs, and values” and that ensures “that patient values guide all clinical decisions” [9].
Relying on Rotter’s 2010 Cochrane Review, the key dimensions identified for Patient Centered Care were communication [10], audit/feedback [11], informative systems [12], evidence-based application [13], multidisciplinary approach [14] and education sessions [11]. With regards to Personalized Medicine, on the other hand, the European Council’s document of 2015 identifies the molecular board [15], evidence-based genetic testing [16] and shared-clinical decision-making [17]. As such, eligible studies were those fulfilling t the definitions of patient-centered care and/or personalized medicine in terms of inclusion of the aforementioned dimensions.
In parallel, when available, relative key success factors and barriers to implementation of such dimensions were reported.

2.3. Study Selection

After removing duplicate records, four researchers (C.C., A.M., R.P., R.P.) independently screened by title and abstract to outline records according to the inclusion criteria aforementioned. Then, the four researchers performed a full text screening of each article to determine eligibility. Disagreements were resolved through discussion with a fifth researcher (A.G.d.B.).
The reference lists of the included studies were hand-searched to locate additional studies via the snowball search method. The study selection was performed from December 2020 to February 2021.

2.4. Data Extraction and Synthesis

Data extraction was conducted by four independent researchers (C.C., A.M., R.P., R.P.) from the end of January to February 2021. A dedicated data extraction form on Excel was used to retrieve the following information for each eligible study:
  • Study identification (first author, title, journal, publication year);
  • Study characteristics (period, country, design);
  • Sample characteristics (stage of breast cancer, sample age, sample ethnicity);
  • Personalized Medicine and Patient centered aspects;
  • Barriers and/or success factors.

2.5. Quality Assessment

Three researchers (A.M., R.P., R.P.) independently conducted the methodological quality assessment, based on the different study designs. Disagreements were resolved by discussion with a fourth researcher (C.C.). The standardised critical appraisal tool (1) Scale for the Assessment of Narrative Review Article SANRA [18] was used to assess narrative reviews; (2) Critical Appraisal Skills Programme, CASP [19] for qualitative research; (3) JBI Critical Appraisal Checklist for cohort studies [20]; (4) JBI Critical Appraisal Checklist for text and opinion [21]; (5) The Newcastle-Ottawa Scale NOS for cross-sectional studies [22]; (6) JBI Critical Appraisal Checklist for systematic review and research syntheses [23]. To summarise the overall evidence quality, we decided to cluster the records retrieved into three categories, based on the number of quality criteria met: group 1, studies satisfied at least 75% of the quality criteria; group 2, studies encountering between 55% and 74% of the quality criteria; and group 3, studies met less than 55% of the quality criteria.

3. Results

A total of 1885 records were collected from all the databases searched. After removing duplicates, the remaining 1806 articles were screened by title and abstract. The full texts of the 83 retained papers were screened. Of these, 25 met the eligibility criteria and were included in the systematic review and in the qualitative analysis.
The process of study screening and selection is reported in Figure 1.

3.1. Results of Quality Assessment

The majority of the included articles were narrative reviews [24,25,26,27,28,29,30,31,32] (36%) and qualitative researches [33,34,35,36,37,38,39] (28%). As reported in Table 1, six [24,25,27,34,40,41] out of 25 articles (24%) were classified in group 1, since they satisfied at least 75% of the quality criteria, while the majority—11 [26,31,33,35,37,38,39,42,43,44,45] out of 25 articles (44%)—were allocated in group 2, meeting between 55% and 74% of the quality criteria. Lastly, 8 [28,29,30,32,36,46,47,48] out of 25 studies (32%) were inserted in group 3, satisfying less than 55% of the quality criteria.

3.2. Outcome Categories

Below, we report findings relative to the key dimensions of Patient Centered Care and Personalized Medicine, alongside relative key success factors and barriers as shown in Table 2.

3.2.1. Patient-Centered Care Key Dimensions

The patient-centered care category included five [27,36,37,42,44] out of twenty-five articles (20%). Findings relative to the key dimensions were:
  • Communication: the description and analysis of communicative skills of clinicians [36] (20%);
  • Audit and feedback: the measurement of quality indicators and compliance with the standards proposed by the European Society on Breast Cancer Specialists (EUSOMA) [27,42] (40%);
  • Informative systems: their utility and effectiveness for management of cancer-related data [37] (20%);
  • Evidence-based application (guidelines, critical pathway, and procedures): the improvement of patients outcome required necessarily the adherence to the guidelines [42,44] (40%).

3.2.2. Personalized Medicine Key Dimensions

Eleven [24,28,30,32,33,34,35,41,43,45,46] out of twenty-five articles (44%) provided information on personalized medicine for the treatment of breast cancer. Results about key dimensions were:
  • Molecular board (compositions and conditions for efficacy): the role, responsibilities and tasks of all members, in particular pathologists and surgeons [24,28,32,33,35] (45%);
  • Evidence-based genetic testing: the benefits and clinical validity of -omics technologies, focusing on BRCA and Oncotype DX [24,30,32,34,35,41,43,45,46] (82%);
  • Shared-clinical decision-making: a positive impact on the selection of targeted therapy and improvements in chemotherapy, endocrine, and chemo-endocrine therapy decisions [24,30,32,34,35,41,43,45,46] (82%).
Only three [24,32,35] out of eleven articles (27%) provided information on all three dimensions, indicating that the combination of these would be necessary and essential to ensure a more accurate and efficacy targeted treatment.

3.2.3. Key Dimensions for Applying Personalized Medicine and Patient-Centered Care

Nine [25,26,29,31,38,39,40,47,48] out of twenty-five articles (36%) reported information on both categories (PM and PC).
In particular, two [40,47] out of nine articles (22%) referred to the molecular board; eight [25,26,29,31,38,39,47,48] (89%) referred to evidence-based genetic testing.
Information on shared-clinical decision-making was reported by six [26,29,31,38,47,48] (66%): in particular, only one [31] described and analyzed several web supports to include the patient in the decision-making process.
Four [29,38,39,40] (44%) referred to communication, focusing on a greater sharing of information during genetic counselling.
One [48] (11%) referred to audit/feedback and two [26,39] (22%) to informative systems. Both agreed on the introduction of scientific tools, such as electronic medical records (EMR), to combine clinical and genomic data.
Evidence-based application was described by only one study [48] (11%), with the implementation of an integrated oncology clinical pathway model (IOCP).
Seven [25,26,29,31,39,40,47] (78%) referred to a multidisciplinary approach: most of them agreed on the need for education and training programs about genetic testing for all members of the multidisciplinary team.

3.3. Success Factors and Barriers in the Management of Breast Cancer Pathway

3.3.1. Success Factors

Analysis of the included articles revealed the following key success factors of the enactment of personalized treatment and patient-centered care models in BC clinical practice, which can be summarized as follows: multiprofessional/multispecialist collaboration; education and training on genetic testing; utilization of personalized medicine prevention techniques; clear communication between clinicians and patients; data derived benchmarking for quality improvement.
More specifically, appropriately training and assembling multi-professional and multi-specialist teams is described as an organizational strength for the treatment of BC [26,28,31,32,33,47]. In breast oncology practice, in fact, the team must necessarily include qualified specialists to bridge the gap between clinical knowledge and genetic potential, especially able to collect and evaluate genomic profiling data [31,33]. The importance of refining clinicians’ training on genetic testing and communication strategies is also linked to clinician-to-patient communication [36,38]: a communicative approach focused on patients and their background consent a better involvement of them in the decision-making process [43]. In addition, measuring and benchmarking the performance of clinical pathways through quality indicators allow us to identify, on one side, weak areas that require improvement and, on the other, those which adhered to clinical guidelines [42,44,48].
Lastly, another key success factor is found in the appropriateness of the genetic test selection process, which must take into account clinical utility and validity, analytical validity, as well as ethical, legal, and social implications [25].

3.3.2. Barriers

Our records allowed us to identify some general barriers that should be improved and overcome in the future, such as the lack of a universal language among health professionals, the uncertain composition of multidisciplinary teams and delays in the adoption of new technologies in clinical practice.
The need for proper training and education for geneticists and clinicians [24,25,39] is not supported by the adoption of a universal genomics vocabulary [41]. Additionally, the unclear definition of the scope of the genetic counseling—or an insufficiently involved geneticist—represents a barrier to proper and adequate communication with the patient [33,38]. From here, the need to define the role of genetic counseling through internal protocols, both before and after the execution of the tests, also serves as a barrier [40].
Moreover, there seems to be lack of clarity on the allocation of tasks and responsibilities among all members of the multidisciplinary team. Especially between oncologists and geneticists, the administration, interpretation and use of genetic tests and -omics technologies are fragmented [35], further confirming the importance of introducing new professional profiles trained and responsible for data collection and analysis, such as data manager [37].
The delay in the adoption of -omic technologies in clinical practice is associated to the lack of clarity in their appropriate timing and use [39,41,44]. Furthermore, the insufficient use of genetic testing is linked to the absence of public reimbursement schemes which disincentivizes their utilization [34,46].

4. Discussion

Authors should discuss the results and how they can be interpreted from the perspective of previous studies and of the working hypotheses. The findings and their implications should be discussed in the broadest context possible. Future research directions may also be highlighted.
We systematically reported on the state-of-the-art of available literature investigating the enactment of personalized treatment and patient-centered care models in BC clinical practice. We also aimed at highlighting the key success factors of such a shift, alongside relative barriers to implementation. The main success factors found in our included articles are the clear definition of roles and responsibilities within a multi-professional collaboration, backed by appropriate training and education programs. Last but not least, there is the need for an adequate communication strategy which includes the adoption of a universal genomic language and the active involvement of the patient in the decision-making process. Overall, it appears that -omics technology cannot rely on a solid organizational structure, neither at the micro level of single facilities or at the macro level of the health system. Compared to El-Alti et al. 2019 [49], which questions whether the relationship between personalized medicine and patient-centered care is a complementary or mutually exclusive one, our study takes a step further and answers the question by supporting the thesis by which these models are indeed synergically complementary.
In fact, PM alone is not sufficient to select the best treatment choice as it focuses mainly on somatic, biological and genetic features of the patient. It is here that the role played by Patient Centered Care ensures the active engagement of the patient by bringing his personal needs and preferences into the decision-making process. Nardini et al. 2021 [50] describe a new healthcare configuration that includes personalized, predictive, preventive, participatory and person-centered care approaches, to be applied to all areas of medicine. Agreeing with such findings, this review recognizes how both models together are needed to ensure a positive and effective change in the path of patient care and attempts to tailor such a transition to the context of breast cancer care.
With the next step being the delivery of personalized care, it becomes central to find solutions to the array of organizational challenges that come with it to allow, on one side, the high degree of specialization, scientific-technical advances and multidisciplinary and multiprofessional coordination, and, on the other, patient participation and the ability to respond to multiple care needs [51].
Internationally, clinical pathways have been recognized as a suitable tool to drive care towards patient-centeredness, and result from a translation of Evidence Based Medicine (EBM) principles into localized contexts (Figure 2), as a strategy to reduce unnecessary clinical variability, costs, fragmentation of care improving outcomes and quality of care [52]. However, it has been argued that committing to one or a few best recommendations and standards may slow down the pace of change in the landscape of oncological care and prevent providers and professionals from being able to deliver individualized treatments that synergize with patient preferences [53].
It is in the recognition of such limitations that it becomes necessary to bring personalized medicine into clinical practice by rendering it an integral part of clinical pathways. Their nature, in fact, allows for merging the ultimate therapeutic advancements and best current evidence with individual patient characteristics and preferences, while still attenuating unnecessary clinical variability.
Typically, patient preferences are left out in the construction process of the “classic Clinical Pathway model” as they are not considered among principal factors. However, when therapeutic options may lead to different results depending on patients’ preferences, patients’ participation in the decision-making process is a keystone of high-quality cancer care. Shared Decision-Making (SDM) can be defined as “an approach where physicians and patients share the best available evidence when faced with the task of making treatment decisions, and where patients are supported to consider options, to achieve informed preferences [54], with positive effects on patient satisfaction cost effectiveness and the number of malpractice lawsuits” [55,56,57] (Maes-Carballo et al., 2020) [58].
In light of the above, the BC Clinical Pathway constitutes an ideal context in which to set-up a SDM system as shown in Figure 3 that allows for a transformation of the standardized application of EBM (Figure 2) into a dynamic and personalized care pathway.
Structuring the pathway on specific moments of shared decision making—to be applied not only between patients and healthcare professionals, but also between healthcare professionals themselves; our model blends personalized medicine and patient centered care determinants, such as each patients’ genetic features (i.e., the genomic profile), impacts on the patient’s health status (including patient safety and treatment adverse effects) and patient reported measures (PROMs and PREMs).
Additionally, however, following the direction taken by Value-Based Healthcare and, in particular Bodenheimer’s Quadruple-Aim framework [59], the next generation of care pathway’s framework must include also other three dimensions: at an organizational micro level, the framework considers care-team sharing, being a determinant of team wellness; at a macro-organizational level, the principles of green oncology, waste containment and impacts on overall budget and accountability, to evaluate the broadest impact possible of the dynamic pathway.

5. Limitations

There are some limitations in this systematic review that should be taken into account when interpreting the results. First of all, broadly speaking, evidence in the current literature of primary studies clearly defining the combined use of personalized medicine and patient-centered care approaches were quite scarce. Secondly, heterogeneity in study designs, in outcome definition and in staging systems adopted (often not at all present in the included studies) prevented us from conducting a meta-analysis and issuing more conclusive results. Furthermore, according to the adopted quality assessment tools, most of the included studies were of moderate–poor quality.

6. Conclusions

In the last few years, patient-centered care has been found to be one of the key elements for improving the quality of breast cancer management. Clinical-care-pathways, especially oncological ones, have certainly contributed to the transparency of the decision-making process. The pressure that personalized medicine is placing in the field of oncology, however, highlights the need to structure organizational models that combine PC care models and PM together. The sustainability of the model proposed in this work would largely benefit from further developments and confirmations through additional research, as well as in ulterior organizational contexts.
