Management of the axilla in breast cancer patients: critical review, regional modified Delphi consensus and implementation in the Tuscan breast network.

PURPOSE: Data from recently trials have provided practice-changing recommendations in management of the axilla in early breast cancer (eBC). However, further controversies have been raised, resulting in heterogeneous diffusion of these recommendations. Our purpose was to obtain a better homogeneity. MATERIAL AND METHODS: In 2021, the Tuscan Breast Network (TBN) established a consensus with the aim to update recommendations in this area. We performed a literature review on axillary management in eBC patients which led to an expert Delphi consensus aiming to explore the gray areas, build consensus and propose evidence-based suggestions for an appropriate management. Thereafter, we investigate their implementation in clinical practice. RESULTS: (1) DCIS patients should have SLN biopsy only in case of mastectomy or in conservative surgery if tumor is in a location that would preclude future nodal sampling or in case of a mass; (2) ALND may be omitted for 1-2 positive SLN patients undergoing BCS in T1-2 tumors with 1-2 SLN positive, eligible for whole-breast irradiation and adjuvant systemic therapies; (3) consider the option of RNI in patients with 1-3 positive lymph nodes and one or more high-risk characteristics; (4) the population identified in 2) should NOT undergo lymph node irradiation as an alternative to axillary surgery and (5) patients with clinically (pre-operatively) positive axilla, or undergoing primary systemic therapy, or outside the criteria reported in 2) must receive additional ALND and/or RT as per local policy. CONCLUSION: This consensus provided a practical tool to stimulate local and national breast surgical and radiotherapy protocols.

Neoadjuvant Systemic Therapy in Early Breast Cancer: Results of a Prospective Observational Multicenter BRIDE Study.

To evaluate the rate of early breast cancer (EBC) patients treated with neoadjuvant systemic therapy (NAT) in Italy, criteria of patient selection and types of therapies delivered, an analysis of 1276 patients with stage I-II-III was conducted out of 1633 patients enrolled in the multicenter prospective observational BRIDE study. A total of 177 patients (13.9%) were treated with NAT and 1099 (85.9%) with surgery; in multivariate analysis, menopausal status, cT, cN, grade, HER2-positive and Triple negative (TN) subgroups were significantly associated with the decision to administer NAT. The type of NAT delivered was influenced by EBC subtype. NAT was administered to 53.2% of HER2+/HR-negative, 27.9% of HER2+/HR+, 7.1% of HER2-negative/HR+ and 30.3% of TN EBC patients. The pCR rates were similar to the ones reported in the literature: 74.2% in HER2+/HR-negative, 52.3% in HER2+/HR+, 17.2% in HER2-negative/HR+ and 37.9% in TN. In clinical practice, patient and tumor characteristics influenced oncologists in the decision to administer NAT in EBC and in the choice of the type of systemic therapy, according to ESMO and AIOM Guidelines. Currently, it is recommended always to evaluate the use of NAT in EBC, mainly in HER2+ and TN patients, considering that pCR is associated with significantly better survival of the patient and that effective therapies are now available for residual disease.

Presence and Role of Associations of Cancer Patients and Volunteers in Specialist Breast Centres: An Italian National Survey of Breast Centres Associated with Senonetwork.

This article aims to present the results of a national, cross-sectional, voluntary, online survey on the presence and roles of associations of breast cancer patients and volunteers in Italian specialist breast centres. The survey was developed according to standard methods. The questionnaire was pre-tested by a random sample of three breast centres, loaded onto the SurveyMonkey platform, and piloted by one volunteer breast centre. The breast centre clinical leads were invited to participate via email. A link to the online instrument was provided. No financial incentives were offered. The results were reported using standard descriptive statistics. The response rate was 82/128 (65%). Members of associations were routinely present in 70% Italian breast centres. Breast centres most often reporting their presence were those certified by the European Society of Breast Cancer Specialists. Patient support (reception and information, listening, identification of needs, and psychological support) was the primary area where associations were reported to offer services. The magnitude of this phenomenon warrants a study to investigate the impact of the activities of associations on the quality of life of patients and on the cost-benefit ratio of the service, and the modes of their interactions with the nursing staff and the medical staff.

Integrating mammography screening programmes into specialist breast centres in Italy: insights from a national survey of Senonetwork breast centres.

BACKGROUND: Despite recommendations, mammography screening is often insufficiently integrated into specialist breast centres. A national, cross-sectional, voluntary, online survey on this issue was carried out among the Italian breast centres associated with Senonetwork, the Italian network of breast cancer services. METHODS: A 73-item questionnaire was created, pre-tested and piloted. Centres integrating and not integrating a screening programme were compared using the unified theory of acceptance and use of technology (UTAUT) model. Centres' clustering was performed using the Gower's distance metric. Groups and clusters were compared with the equality-of-means test. RESULTS: The response rate was 82/128 (65%). Overall, 84% (69/82) breast centres reported a collaboration with a screening programme in performing and/or reading mammograms and in the diagnostic work-up of women with abnormal screening results. The same proportion was observed among those centres responding to all questions (62/74). Performance expectancies (or the perceived usefulness of integration in terms of clinical quality, patient convenience, ease of job, and professional growth), satisfaction and motivation were higher in those centres collaborating with the screening programme. Effort expectancy indicators (or the degree to which the respondents believe that the integration is easy to implement) and those concerning the existence of facilitating conditions were lower both in centres collaborating and not collaborating with the screening programme. Among the former, six clusters of centres, distributed from 'no integration' to 'high', were identified. In cluster analysis, the highest level of integration was associated with higher agreement that integration eases the job, offers better opportunities for professional growth, and makes the working environment more satisfactory. The least integrated cluster assigned the lowest score to the statement that local health authority made available the resources needed. CONCLUSIONS: While confirming the positive effects of integrating screening programmes into breast centres, this survey has brought to light specific difficulties that must be faced. The results provide insights into the importance of integration focusing on the perspectives of professional career and motivation. The deficiency of facilitating conditions to integration is modifiable. Screening professionals' societies may have a role as initiators of the integration. Other supporting actions may be included in health laws at the national and regional level.

A direct method for the identification of patterns of care using administrative databases: the case of breast cancer.

OBJECTIVES: To identify and provide lists of procedures and drugs related to diagnosis and treatment of breast cancer. These lists can be used for the estimation of the cost of illness. METHODS: The method consists of identifying lists of procedures/interventions/drugs related to the tumour of interest, drawn by a panel of expert clinicians and oncologists on the basis of clinical guidelines and current practice. The lists are applied to data referring to breast cancer female patients, collected by population-based Cancer Registries and linked at individual level with information on health care treatments. A comparison with lists obtained via the matched control method is implemented. RESULTS: The distribution of administered procedures and drug prescriptions is coherent with the patient clinical pathway: surgery is the main cause of hospitalization in the first year since diagnosis, diagnostic and monitoring interventions are more frequent in the following years (recurrences detection), and at end-of-life (palliative care). Most outpatient services are due to diagnosis and monitoring, one third of services in the first year since diagnosis is radiotherapy and chemotherapy. Drugs prescribed to patients and sold in pharmacy include hormonal drugs as first course treatment and analgesics as palliative care. CONCLUSIONS: This direct method represents a valid alternative to the matched control method in describing patterns of care and costs related to the entire disease pathway. It is particularly suitable in case of cancer sites with complex patterns of care, such as breast cancer. The lists of codes developed here are based on international classification systems and can be easily applicable to other countries.

ALTERTASTE: improving food pleasure and intake of oncology patients receiving chemotherapy.

ALTERTASTE is a prospective study to evaluate changes in taste/flavor perception and food preferences in patients treated with adjuvant or neoadjuvant chemotherapy for breast or colorectal cancer. The study adopts a longitudinal approach. Taste and odor responsiveness, food preferences and habits, emotions elicited by foods, and quality of life will be measured at six-time points: before chemotherapy (T0), after two cycles (T1, after around 1 month), after four cycles (T2, after around 2 months), after six cycles (T3, after around 4 months), at the end of chemotherapy (T4, after around 6 months) and 3 months after the conclusion of the therapy (T5). In addition, patients will be characterized for oral responsiveness and their psychological traits and attitudes toward food. The ALTERTASTE trial is expected to improve the understanding of the impact of chemotherapy on taste and smell and the repercussions of these alterations on food behaviors. Furthermore, the trial aims to develop an easy and reliable procedure to test smell, taste and food behavior alterations to allow a routine measure with patients. Clinical trial registration: NCT04495387 (ClinicalTrials.gov).

Lay abstract Malnutrition (under- or over-nutrition) is highly prevalent in cancer patients receiving chemotherapy and is an important predictor of morbidity, mortality, treatment response and toxicity. Alterations in taste and smell are frequently reported as side effects of chemotherapy and may contribute strongly to malnutrition through an impact on eating behaviors and to a worse quality of life. ALTERTASTE is a prospective longitudinal study to evaluate changes in taste/flavor perception and food preferences in patients treated with chemotherapy for breast, colon or rectal cancer. Taste and odor responsiveness, food preferences and habits, emotions elicited by foods, and quality of life will be measured at six-time points: before chemotherapy (T0), after two cycles (T1, after around 1 month), after four cycles (T2, after around 2 months), after six cycles (T3, after around 4 months), at the end of chemotherapy (T4, after around 6 months) and 3 months after the conclusion of the therapy (T5). In addition, patients will be characterized for oral responsiveness and psychological traits and attitudes toward food. The ALTERTASTE trial is expected to improve the understanding of the impact of chemotherapy on taste and smell and the repercussions of these alterations on food behaviors.

Patterns of care and cost profiles of women with breast cancer in Italy: EPICOST study based on real world data.

OBJECTIVES: To estimate total direct health care costs associated to diagnosis and treatment of women with breast cancer in Italy, and to investigate their distribution by service type according to the disease pathway and patient characteristics. METHODS: Data on patients provided by population-based Cancer Registries are linked at individual level with data on health-care services and corresponding claims from administrative databases. A combination of cross-sectional approach and a threephase of care decomposition model with initial, continuing and final phases-of-care defined according to time occurred since diagnosis and disease outcome is adopted. Direct estimation of cancer-related costs is obtained. RESULTS: Study cohort included 49,272 patients, 15.2% were in the initial phase absorbing 42% of resources, 79.7% in the continuing phase absorbing 44% of resources and 5.1% in the final phase absorbing 14% of resources. Hospitalization was the most important cost driver, accounting for over 55% of the total costs. CONCLUSIONS: This paper represents the first attempt in Italy to estimate the economic burden of cancer at population level taking into account the entire disease pathway and using multiple current health care databases. The evidence produced by the study can be used to better plan resources allocation. The model proposed is replicable to countries with individual health care information on services and claims.

Adjuvant endocrine therapy in premenopausal patients with hormone receptor-positive early breast cancer: Evidence evaluation and GRADE recommendations by the Italian Association of Medical Oncology (AIOM).

Premenopausal women with hormone receptor-positive early breast cancer are candidates for adjuvant endocrine therapy, as recommended by the major international guidelines. To date, adjuvant endocrine options for premenopausal women include tamoxifen with or without ovarian function suppression (OFS) or an aromatase inhibitor with OFS. Multiple strategies for endocrine treatment of premenopausal women with hormone-responsive breast cancer have been assessed, and the results of randomised clinical trials have been reported over the last years. Despite this evidence, the optimal algorithm for endocrine therapy for premenopausal women with hormone receptor-positive early stage invasive breast cancer shows open questions regarding the role of OFS in addition to tamoxifen and the optimal use of hormonal agents. The panel of the Italian Association of Medical Oncology (AIOM) Clinical Practice Guidelines on Breast Cancer applied the Grades of Recommendation, Assessment, Development and Evaluation (GRADE) methodology on three critical questions on the choice of the adjuvant hormonal therapy in premenopausal breast cancer patients to summarise available evidence and to create recommendations to help physicians in their clinical practice.

Severe thrombocytopenia after trastuzumab retreatment: a case report.

BACKGROUND: Trastuzumab prolongs survival of human epidermal growth factor receptor 2-positive breast cancer patients in both the adjuvant and metastatic settings. Currently toxicity data are not available on retreatment of metastatic breast cancer patients who relapse after adjuvant trastuzumab. We report one patient with metastatic breast cancer who developed acute thrombocytopenia after trastuzumab infusion. This patient had trastuzumab treatment in the adjuvant setting. CASE PRESENTATION: A 70-year-old Caucasian woman received a diagnosis of metastatic breast cancer four years after her initial diagnosis of locally advanced, hormone receptors-positive, human epidermal growth factor receptor 2-positive breast cancer. Trastuzumab retreatment was planned. Less than 24 hours after trastuzumab infusion, the patient was admitted to the hospital for the appearance of diffuse petechial hemorrhages and ecchymosis. The patient was confirmed to have a severe trastuzumab-induced thrombocytopenia. A rapid and complete recovery was observed after high-dose intravenous corticosteroids and immunoglobulin. No trastuzumab retreatment was attempted. CONCLUSION: Among the reported cases of trastuzumab-induced thrombocytopenia, this is the first report in the literature occurring in a patient retreated with trastuzumab after adjuvant therapy.

Initial treatment for newly diagnosed elderly colorectal cancer patients: patterns of care in Italy and the United States.

Cancer is a major component of health-care expenditures in most developed countries. The costs of cancer care are expected to increase due to rising incidence (as the population ages) and increasing use of targeted anticancer therapies. However, epidemiological analysis of patterns of care may be required prior to empirically well-grounded cost analyses. Additionally, comparisons of care between health-care delivery systems and countries can identify opportunities to improve practice. They can also increase understanding of patient outcomes and economic consequences of differences in policies related to cancer screening, treatment, and programs of care. In this study, we compared patterns of colorectal cancer treatment during the first year following diagnosis in two cohorts of elderly patients from some areas of Italy and the United States using cancer registry linked to administrative data. We evaluated hospital use, initial treatments (surgery, chemotherapy, and radiation), and timeliness of surgery and adjuvant therapy, taking into account patient characteristics and clinical features, such as stage at diagnosis and the cancer subsite. We observed greater use of adjuvant chemotherapy in stage III and IV colon cancer patients and adjuvant therapy in all stages of rectal cancer patients in the US cohort. We found a higher rate of open surgeries in the Italian cohort, a similar rate of hospitalization, but a higher number of hospital days in the Italian cohort. However, in spite of structural differences between the United States and Italy in health-care organization and delivery as well as in data collection, patterns of care and the timing of care in the year after diagnosis are generally similar among patients within stage of disease at diagnosis. Comparative studies of the costs associated with patterns of cancer care will be important for future research.

Cost profiles of colorectal cancer patients in Italy based on individual patterns of care.

BACKGROUND: Due to changes in cancer-related risk factors, improvements in diagnostic procedures and treatments, and the aging of the population, in most developed countries cancer accounts for an increasing proportion of health care expenditures. The analysis of cancer-related costs is a topic of several economic and epidemiological studies and represents a research area of great interest to public health planners and policy makers. In Italy studies are limited either to some specific types of expenditures or to specific groups of cancer patients. Aim of the paper is to estimate the distribution of cancer survivors and associated health care expenditures according to a disease pathway which identifies three clinically relevant phases: initial (one year following diagnosis), continuing (between initial and final) and final (one year before death). METHODS: The methodology proposed is based on the reconstruction of patterns of care at individual level by combining different data sources, surveillance data and administrative data, in areas covered by cancer registration. RESULTS: A total colorectal cancer-related expenditure of 77.8 million Euros for 18012 patients (corresponding to about 4300 Euros per capita) is estimated in 2006 in two Italian areas located in Tuscany and Veneto regions, respectively. Cost of care varies according to the care pathway: 11% of patients were in the initial phase, and consumed 34% of total expenditure; patients in the final (6%) and in the continuing (83%) phase consumed 23% and 43% of the budget, respectively. There is an association between patterns of care/costs and patients characteristics such as stage and age at diagnosis. CONCLUSIONS: This paper represents the first attempt to attribute health care expenditures in Italy to specific phases of disease, according to varying treatment approaches, surveillance strategies and management of relapses, palliative care. The association between stage at diagnosis, profile of therapies and costs supports the idea that primary prevention and early detection play an important role in a public health perspective. Results from this pilot study encourage the use of such analyses in a public health perspective, to increase understanding of patient outcomes and economic consequences of differences in policies related to cancer screening, treatment, and programs of care.

Feasibility of evaluating quality cancer care using registry data and electronic health records: a population-based study.

OBJECTIVE: To evaluate the quality of patients care, a set of indicators of the standards of cancer care were defined. PARTICIPANTS: We developed a set of indicators to assess the implementation in daily practice of recommendation produced by a regional network (Istituto Toscano Tumori). This set was tested in a retrospective study in the resident population of the Tuscany Region; the regional health system is organized on 12 local health authorities which refer to three macro areas (Area Vasta). The study included incident colorectal, lung and breast cancer cases listed in 2004 for the Tuscan Cancer Registry, a population-based registry which collected tumor cases diagnosed in all residents in Tuscany. Electronic data from registry database were used to determine the compliance with each indicator for patients in 2004. To validate the results, an ad hoc clinical survey including the same geographical area for the year 2006 was performed. INTERVENTION: None. MAIN OUTCOME MEASURES: The proportion of patients who fulfilled each of the indicators. RESULTS: Our study showed the feasibility of the evaluation of the quality of cancer care using cancer registry population-based data and major computerized information systems. The estimation of the selected indicators confirmed a good homogeneity among areas, and globally revealed a good intraregional performance. CONCLUSIONS: Further work is needed to develop specific quality measures, particularly about structural data and to continually revise indicators of quality of care. Data from a cancer registry, however, can be useful to evaluate quality of cancer care.
