Potential of MRI in Assessing Treatment Response After Neoadjuvant Radiation Therapy Treatment in Breast Cancer Patients: A Scoping Review. Clin Breast Cancer 2024:S1526-8209(24)00136-8. [PMID: 38906720 DOI: 10.1016/j.clbc.2024.05.010] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/09/2023] [Revised: 05/07/2024] [Accepted: 05/26/2024] [Indexed: 06/23/2024]
Abstract
The objective of this scoping review is to evaluate the potential of Magnetic Resonance Imaging (MRI) and to determine which of the available MRI techniques reported in the literature are the most promising for assessing treatment response in breast cancer patients following neoadjuvant radiotherapy (NRT). Ovid Medline, Embase, CINAHL, and Cochrane databases were searched to identify relevant studies published from inception until March 13, 2023. After primary selection, 2 reviewers evaluated each study using a standardized data extraction template, guided by set inclusion and exclusion criteria. A total of 5 eligible studies were selected. The positive and negative predictive values for MRI predicting pathological complete response across the studies were 67% to 88% and 76% to 85%, respectively. MRI's potential in assessing postradiotherapy tumor sizes was greater for volume measurements than uni-dimensional longest diameter measurements; however, overestimation in surgical tumor sizes was observed. Apparent diffusion coefficient (ADC) values and Time to Enhance (TTE) was seen to increase post-NRT, with a notable difference between responders and nonresponders at 6 months, indicating a potential role in assessing treatment response. In conclusion, this review highlights tumor volume measurements, ADC, and TTE as promising MRI metrics for assessing treatment response post-NRT in breast cancer. However, further research with larger cohorts is needed to confirm their utility. If MRI can accurately identify responders from nonresponders to NRT, it could enable a more personalized and tailored treatment approach, potentially minimizing radiation therapy related toxicity and enhancing cosmetic outcomes.

Front Public Health 2021; 9:678785. [PMID: 34604152 PMCID: PMC8484711 DOI: 10.3389/fpubh.2021.678785] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/25/2021] [Accepted: 08/26/2021] [Indexed: 11/13/2022] Open
Abstract
Background: Intravenous (IV) ribavirin is not approved in US and European Union, but it is authorized in China. Significant teratogenic and embryocidal effects of ribavirin have been found in almost all animal studies, it is critical to investigate the prevalence and trends of the utilization of IV ribavirin among reproductive age population. Objective: To evaluate the prevalence and trends of IV ribavirin use among reproductive-age population in 2010–2017. Methods: The study design of our study is retrospective cross-sectional study based on healthcare database. We identified and extracted the data of residents aged 18–44 years by using Yinzhou healthcare information database at 21 January, 2018. A cohort of IV ribavirin users were identified through outpatient prescription records in 3 general hospitals and 24 community health centers from 2010 to 2017. We reported the number, proportion, and prevalence of the exposure to IV ribavirin stratified by sex, age, marital status, education level, occupation, hospital level, calendar year, diagnosis, and dosage. The overall trends of IV ribavirin use, and the trends in different levels of hospital and common diagnoses were further analyzed and described. Result: During the study period, the prevalence of IV ribavirin use among reproductive-age adults was 6.02% (48,287/801,667). Relatively higher prevalence were found in adults aged 40–44 (8.04%, 95% CI: 7.90–8.17), unmarried patients (8.91%, 95% CI: 8.74–9.08), and who had more than 9 years of education (6.82%, 95% CI: 6.74–6.90). Compared to secondary and tertiary hospitals, IV ribavirin was more likely to be dispensed in primary hospitals (19.44%, 95% CI: 19.28–19.61). The most common diagnoses were acute upper respiratory infections (AURIs), accounting for 80% of the patients exposed to IV ribavirin. For patients with AURIs, the prevalence of IV ribavirin was nearly 30%. Overall, the prevalence of IV ribavirin use decreased from 1.72% in 2010 to 0.24% in 2017. Conclusion: We found IV ribavirin was mainly used for AURIs which suggested that a large amount of IV ribavirin use was probably inappropriate. The prevalence was decreasing by 87% over the past 8 years, and we encourage clinicians and pharmacists to continually avoid inappropriate use of IV ribavirin.

Healthcare providers' adherence to breast cancer guidelines in Europe: a systematic literature review. Breast Cancer Res Treat 2020; 181:499-518. [PMID: 32378052 PMCID: PMC7220981 DOI: 10.1007/s10549-020-05657-8] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/25/2020] [Accepted: 04/27/2020] [Indexed: 12/19/2022]
Abstract
Purpose Clinical guidelines’ (CGs) adherence supports high-quality care. However, healthcare providers do not always comply with CGs recommendations. This systematic literature review aims to assess the extent of healthcare providers’ adherence to breast cancer CGs in Europe and to identify the factors that impact on healthcare providers’ adherence. Methods We searched for systematic reviews and quantitative or qualitative primary studies in MEDLINE and Embase up to May 2019. The eligibility assessment, data extraction, and risk of bias assessment were conducted by one author and cross-checked by a second author. We conducted a narrative synthesis attending to the modality of the healthcare process, methods to measure adherence, the scope of the CGs, and population characteristics. Results Out of 8137 references, we included 41 primary studies conducted in eight European countries. Most followed a retrospective cohort design (19/41; 46%) and were at low or moderate risk of bias. Adherence for overall breast cancer care process (from diagnosis to follow-up) ranged from 54 to 69%; for overall treatment process [including surgery, chemotherapy (CT), endocrine therapy (ET), and radiotherapy (RT)] the median adherence was 57.5% (interquartile range (IQR) 38.8–67.3%), while for systemic therapy (CT and ET) it was 76% (IQR 68–77%). The median adherence for the processes assessed individually was higher, ranging from 74% (IQR 10–80%), for the follow-up, to 90% (IQR 87–92.5%) for ET. Internal factors that potentially impact on healthcare providers’ adherence were their perceptions, preferences, lack of knowledge, or intentional decisions. Conclusions A substantial proportion of breast cancer patients are not receiving CGs-recommended care. Healthcare providers’ adherence to breast cancer CGs in Europe has room for improvement in almost all care processes. CGs development and implementation processes should address the main factors that influence healthcare providers' adherence, especially patient-related ones. Registration: PROSPERO (CRD42018092884).

Abstract
AIM To assess the adherence of physicians to the Medical-Care Guidelines for Malignant Breast Tumors in Mexico, before and after the allocation of federal subsidies from the Catastrophic Health Expenditure Fund (FPGC by its Spanish initials) to accredited hospitals, a strategy implemented with the view of offering free treatment to women with breast cancer (BC). MATERIAL AND METHODS Based on a cross-sectional design, we gathered information on 479 BC patients who had been attended to at in four FPGC-accredited hospitals. Analysis centered on those treated within either three years before or three years after the accreditation of their attending hospitals. The four hospitals analyzed were located in the North, South, West and Center of the country. Information on all medical procedures performed during treatment was drawn from hospital medical records. Information on the socio-demographic characteristics of the patients was obtained by means of face-to-face interviews conducted in their homes. RESULTS Adherence of physicians to the Guidelines grew by 12.8 percent (from 43.4 to 56.2 percent) after FPGC accreditation (p<0.001) and varied according to the clinical stage of the disease, with much lower levels of adherence observed in the advanced stages (p<0.05). CONCLUSIONS The FPGC strategy increased the adherence of physicians to the Medical-Care Guidelines for Malignant Breast Tumors in Mexico.

Abstract
Aims and background Project RIGHT (Research for the Identification of the most effective and hIGHly accepted clinical guidelines for cancer Treatment) is promoted by the Italian Association of Medical Oncology (AIOM) to evaluate the concordance between AIOM breast cancer guidelines and clinical practice in Italy. In RIGHT-1, feasibility and the appropriateness of indicators were assessed in patients with early breast cancer. RIGHT-2 evaluated the compliance with guidelines in a nationwide program. Methods Thirty-five Italian centers participated in the RIGHT-2 survey. Ten indicators were evaluated to verify an agreement between 2005 AIOM breast cancer guidelines and practice. Patients with clinical stage I-II invasive breast cancer, age ≤70 years, who had their first visit at the oncology center between October 2005 and November 2006 were included. Results In RIGHT-2, ≥90% adherence for the diagnosis indicator and three therapy indicators were observed. The lowest degree of compliance (0%) was observed for the follow-up indicator in asymptomatic patients. Conclusions In RIGHT-2, compliance to the 2005 AIOM breast cancer guidelines was 64%. When the follow-up indicator was eliminated, overall adherence to AIOM guidelines was 71%. The results highlight the need to continue improving the already good standards of breast cancer care.

Abstract
Postoperative radiotherapy (RT) is the standard of care for early stage breast cancer. It reduces the risk for local recurrence and prolongs survival. We assessed whether, the omission of RT because of patient's preference may influence the prognosis and, thus, the quality of cancer care. Detailed information from a prospectively collected database of a breast cancer center was analyzed. Multiple regression analysis and univariate and multivariate analysis for risk factors for recurrence were performed. The entire cohort of primary breast cancer patients in a given time period was analyzed. Data from 1903 patients undergoing treatment at breast cancer center between 2003 and 2008 were used. All patient underwent breast conserving surgery and RT was performed for all patients of the cohort. Local tumor control and disease-free survival were calculated. After a median follow-up of 2.18 years (maximum 6.39 years), 5.5% of patients did not follow guideline-based recommendations for RT. There was a significant correlation between noncompliance and patient's age, adjuvant hormonal therapy (97.0%), and adjuvant chemotherapy (96.8%). Seventy local recurrences occurred that corresponds to a local recurrence rate of 3.9%. The difference in regard to local recurrence-free 5-year survival between the compliant patients and the noncompliant patients is absolute 17.9 (93.3% and 75.4%). Noncompliant patients had suffered a 5.02-fold increased risk of local recurrence than compliant patients. The omission of RT after breast-conserving surgery results in a higher local failure rate and significantly worsens clinical outcome. Age may play an important role because of the comorbidities of aged patients or the assumed low RT tolerance in this group. On a clinical level, this data suggests that improvement is needed to correct this situation, and the question remains as to how best to improve RT compliance.

Abstract
Lumpectomy is performed in a small but growing proportion of men with breast cancer. It is unknown whether men undergoing breast-conserving surgery (BCS) receive care compliant with breast cancer treatment guidelines. Patients with breast cancer in the surveillance, epidemiology, and end results (SEER) database who underwent lumpectomy between 1983 and 2009 were identified. Gender differences in the receipt of lymph node staging and adjuvant radiation therapy were assessed. Multivariate logistic regression was utilized to evaluate the independent association of gender on these outcomes. The influence of gender on breast cancer-specific survival (BCSS) was analyzed. 382,030 of 824,408 (46.3 %) women compared to 712 of 6,039 (11.8 %) men with breast cancer underwent lumpectomy. Men were older, more likely to be black, less likely to have stage I disease and more likely to have stage IV disease. Only 59.2 % of men had lymph nodes sampled at the time of surgery compared to 81.6 % of women (p < 0.0001). In addition, only 35.4 % of men received adjuvant breast radiation therapy compared to 69.8 % of women (p < 0.0001). After controlling for age, race, stage, grade, and year of diagnosis, female gender was significantly associated with receiving adjuvant radiation therapy (OR 2.9, 95 % CI 2.4-3.4) and lymph node staging (OR 1.6, 95 % CI 1.3-1.90). Five- and ten-year BCSS were 88.0 and 83.5 % for men compared to 93.2 and 88.2 % for women (p < 0.001). Men with breast cancer are less likely to receive lymph node staging or adjuvant radiation therapy following BCS compared to women.

Abstract
AIM The study aim was to determine the frequency with which women decline clinicians' treatment recommendations and variations in this frequency by age, cancer and service descriptors. DESIGN The study included 36,775 women diagnosed with early invasive breast cancer in 1998-2005 and attending Australian and New Zealand breast surgeons. Rate ratios for declining treatment were examined by descriptor, using bilateral and multiple logistic regression analyses. Proportional hazards regression was used in exploratory analyses of associations with breast cancer death. RESULTS 3.4% of women declined a recommended treatment of some type, ranging from 2.6% for women under 40 years to 5.8% for those aged 80 years or more, and with parallel increases by age presenting for declining radiotherapy (p<0.001) and axillary surgery (p=0.006). Multiple regression confirmed that common predictors of declining various treatments included low surgeon case load, treatment outside major city centres, and older age. Histological features suggesting a favourable prognosis were often predictive of declining various treatments, although reverse findings also applied with women with positive nodal status being more likely to decline a mastectomy and those with larger tumours more likely to decline chemotherapy. While survival analyses lacked statistical power due to small numbers, higher risks of breast cancer death were suggested, after adjusting for age and conventional clinical risk factors, (1) for women not receiving breast surgery for unstated reasons (RR=2.29; p<0.001); and (2) although not approaching statistical significance p≥ 0.200), for women declining radiotherapy (RR=1.22), a systemic therapy (RR1.11), and more specifically, chemotherapy (RR=1.41). CONCLUSIONS Women have the right to choose their treatments but reasons for declining recommendations require further study to ensure that choices are well informed and clinical outcomes are optimized.

Abstract
Background Great variability in breast cancer (BC) treatment practices according to patient, tumour or organisation of care characteristics has been reported but the relation between these factors is not well known. In two French regions, we measured compliance with Clinical Practice Guidelines for non-metastatic BC care management and identified factors associated with non-compliance at clinical and organisational levels. Methods Eligible patients had invasive unilateral BC without distant metastases and at least two contacts with one of the two regional healthcare systems (2003-2004) in the first year after diagnosis. Medical data were collected from patient medical records in all public and private hospitals (99 hospitals). The care process was defined by 20 criteria: clinical decisions for treatment and therapeutic procedures. Each criterion was classified according to level of compliance ("Compliant", "Justifiable" and "Not Compliant") and factors of non-compliance were identified (mixed effect logistic regression). Results 926 women were included. Non-compliance with clinical decisions for treatment was associated with older patient age (OR 2.1; 95%CI: 1.3-3.6) and region (OR 3.0; 95%CI: 1.2-7.4). Non-compliance with clinical decisions for radiotherapy was associated with lymph node involvement or the presence of peritumoural vascular invasion (OR 1.5; 95%CI: 1.01-2.3) and non-compliance with overall treatment (clinical decisions for treatment + therapeutic procedures) was associated with the presence of positive lymph nodes (OR 2.0; 95%CI: 1.2-3.3), grade III versus grade I (OR 2.9; 95%CI: 1.4-6.2), and one region of care versus another (OR 3.5; 95%CI: 1.7-7.1). Finally, heterogeneity of compliance in overall treatment sequence was identified between local cancer units (p < 0.05). Conclusion This study provides interesting insights into factors of non-compliance in non-metastatic BC management and could lead to quality care improvements.

OBJECTIVE To assess the compliance of the surveillance colonoscopy waiting list with ACPGBI/BSG guidelines for colonoscopy follow-up and to measure the impact of adjusting referrals to be inline with the guidelines. DESIGN AND SETTING This is a quantitative five-stage clinical audit cycle involving a large patient cohort from the Kent and Medway Cancer Network, which includes seven hospitals across four NHS Hospital Trusts and an estimated population of 1.8 million. PARTICIPANTS 3020 patients were waiting for a surveillance colonoscopy. Their notes were reviewed and the indications for colonoscopy were compared with the ACPGBI/BSG 2002 guidelines. INTERVENTIONS Those patients whose referral to the surveillance colonoscopy waiting list was not found to be compliant were adjusted to be inline with the guidelines. MAIN OUTCOME MEASURES The impact of adjusting the surveillance colonoscopy waiting list on the diagnostic colonoscopy service was assessed by measuring the average waiting times for a colonoscopy before and after the intervention. RESULTS Around 22% (n = 664) of surveillance colonoscopy referrals were inline with the guidelines, 51% (n = 1540) could be cancelled from the list and 27% (n = 816) could be given a new date. Implementing these recommendations reduced the average wait for a diagnostic colonoscopy from 76.8 to 56.0 days (P = 0.0022). CONCLUSION Following guidelines for surveillance colonoscopy can reduce waiting times for diagnostic colonoscopy. This allows a faster patient journey for diagnostic colonoscopy and a uniform plan for duration and frequency of surveillance colonoscopy. However, this action promoted serious debate on the social, moral and ethical issues.

Abstract
BACKGROUND Palliative care should be provided according to the individual needs of the patient, caregiver and family, so that the type and level of care provided, as well as the setting in which it is delivered, are dependent on the complexity and severity of individual needs, rather than prognosis or diagnosis [1]. This paper presents a study designed to assess the feasibility and efficacy of an intervention to assist in the allocation of palliative care resources according to need, within the context of a population of people with advanced cancer. METHODS/DESIGN People with advanced cancer and their caregivers completed bi-monthly telephone interviews over a period of up to 18 months to assess unmet needs, anxiety and depression, quality of life, satisfaction with care and service utilisation. The intervention, introduced after at least two baseline phone interviews, involved a) training medical, nursing and allied health professionals at each recruitment site on the use of the Palliative Care Needs Assessment Guidelines and the Needs Assessment Tool: Progressive Disease - Cancer (NAT: PD-C); b) health professionals completing the NAT: PD-C with participating patients approximately monthly for the rest of the study period. Changes in outcomes will be compared pre-and post-intervention. DISCUSSION The study will determine whether the routine, systematic and regular use of the Guidelines and NAT: PD-C in a range of clinical settings is a feasible and effective strategy for facilitating the timely provision of needs based care.

Abstract
Although treatment recommendations have been advocated for all women with early breast cancer regardless of age, it is generally accepted that different treatments are preferred based on the age of the patient. The aim of this study was to assess the pattern of breast cancer surgery after adjusting for other major prognostic factors in relation to patient age. Data on cancer characteristics and surgical procedures in 31,298 patients with early breast cancer reported to the National Breast Cancer Audit between 1999 and 2006 were used for the study. There was a close association between age and surgical treatment pattern after adjusting for other prognostic factors, including tumor size, histologic grade, number of tumors, lymph node positivity, lymphovascular invasion (LVI), and extensive intraduct component. Breast Conserving Surgery (BCS) was highest among women aged <or=40 years (OR = 1.140; 95% CI: 1.004-1.293) compared to women aged 51-70 years (reference group). BCS was lowest in women aged >70 years (OR = 0.498, 95% CI: 0.455-0.545). Significantly more women aged <or=50 years underwent more than one operation for breast conservation (20.4-24.8%) compared with women aged >50 years (11.4-17.0%). Women aged >70 years were more likely to receive no surgical treatment, 3.5% versus 1.0-1.3% in all other age groups (<or=40, 41-50 51-70 years). There is an association between patient age and the type of breast cancer surgery for women in Australia and New Zealand. Women age <or=40 years are more likely to undergo BCS despite having adverse histologic features and have more than one procedure to achieve breast conservation. Older women (>70 years) more commonly undergo mastectomy and are more likely to receive no surgical treatment.

Abstract
BACKGROUND The Tamoxifen and Exemestane Adjuvant Multinational (TEAM) trial investigates the efficacy and safety of adjuvant exemestane alone and in sequence after tamoxifen in postmenopausal women with hormone-sensitive early breast cancer. As there was a nationwide participation in The Netherlands, we studied the variations in patterns of care in the Comprehensive Cancer Centre Regions (CCCRs) and compliance with national guidelines. METHODS Clinicopathological characteristics, carried out local treatment strategies and adjuvant chemotherapy data were collected. RESULTS From 2001 to January 2006, 2754 Dutch patients were randomised to the study. Mean age of patients was 65 years (standard deviation 9). Tumours were < or =2 cm in 46% (within CCCRs 39%-50%), node-negative disease varied from 25% to 45%, and PgR status was determined in 75%-100% of patients. Mastectomy was carried out in 55% (45%-70%), sentinel lymph node procedure in 68% (42%-79%) and axillary lymph node dissections in 77% (67%-83%) of patients, all different between CCCRs (P < 0.0001). Adjuvant chemotherapy was given in 15%-70% of eligible patients (P < 0.001). DISCUSSION In spite of national guidelines, breast cancer treatment on specific issues widely varied between the various Dutch regions. These data provide valuable information for breast cancer organisations indicating (lack of) guideline adherence and areas for breast cancer care improvement.

Abstract
BACKGROUND Besides basic, illness- and patient-oriented research, outcomes research is regarded as the fourth pillar of modern health care systems. Outcomes research investigates both the desirable and adverse effects of medical and surgical interventions under day-to-day conditions. METHOD Because of rigorous entry criteria and selection of eligible subjects, the efficacy of a certain treatment derived from clinical experiments (i.e. classic randomized trials) may not necessarily be transferred to common patient populations or clinical settings. Apart from efficacy, a valuable (thus reimbursable) diagnostic or therapeutic procedure must prove its effectiveness in clinical practice as well. Demanding study designs are necessary to model effectiveness and to separate the observed intervention-related effects from bias and confounding. RESULTS Registries and pragmatic randomized trials may represent the most appropriate modalities to establish outcomes research in trauma and orthopaedic surgery. Good examples for interventions still needing proof of effectiveness are kyphoplasty and vertebroplasty, navigated surgery, damage control, interlocking implants and bone growth factors. Revealing over- and undersupply, generating negative lists (i.e. interventions of questionable or almost nil effectiveness) and integrating patients as co-therapists requires networking between hospitals and private practitioners. CONCLUSION Also, since outcomes research is a societal need, its development and funding must be ensured by all providers and payers of health care services.

Abstract
OBJECTIVE To explore an approach to measuring the quality of decisions made in the treatment of early stage breast cancer, focusing on patients' decision-specific knowledge and the concordance between patients' stated preferences for treatment outcomes and treatment received. METHODS Candidate knowledge and value items were identified after an extensive review of the published literature as well as reports on 27 focus groups and 46 individual interviews with breast cancer survivors. Items were subjected to cognitive interviews with six additional patients. A preliminary decision quality measure consisting of five knowledge items and four value items was pilot tested with 35 breast cancer survivors who also completed the control preferences scale and the decisional conflict scale (DCS). RESULTS Preference for control and knowledge did not vary by treatment. The mean of the participants' knowledge scores was 54%. There was no correlation between the knowledge scores and the informed subscale of the DCS (Pearson r = .152, n = 32, p = 0.408). Patients who preferred to keep their breast were over five times as likely to have breast-conserving surgery than those who did not (OR 5.33, 95% CI (1.2, 24.5), p = 0.06). Patients who wanted to avoid radiation were six times as likely to choose mastectomy than those who did not (OR 6.4, 95% CI (1.34, 30.61), p = 0.04). CONCLUSION Measuring decision quality by assessing patients' decision-specific knowledge and concordance between their values and treatment received, is feasible and important. Further work is necessary to overcome the methodological challenges identified in this pilot work. PRACTICE IMPLICATIONS Guidelines for early stage breast cancer emphasize the importance of including patients' preferences in decisions about treatment. The ability of doctors and patients to make decisions that reflect the considered preferences of well-informed patients can and should be measured.

Abstract
To identify actionable elements for improving best practice, this study examined the relative effects of patient, surgeon and hospital factors on surgical treatment variation of 2,929 early breast cancer patients, diagnosed from January 1998 to January 2002 in the region of the Comprehensive Cancer Centre North-Netherlands. Multilevel logistic regression was used to analyze the hierarchically structured data. Apart from the patient level, 43.3% of the treatment variation was due to the hospital and 56.7% to the surgeon, after adjustment for patient characteristics. Although hospital factors like volume, teaching status, and management and policy contributed to this variation, multidisciplinary care seemed the most important actionable hospital factor. Although the surgeon was shown to be an important starting point for quality improvement, actionable elements seemed difficult to identify as factors like surgeon experience and volume were not conclusive and significant variance on this level remained (sigma2 = 0.149, SE 0.053). We conclude that multidisciplinary care can improve best practice and that further research into actionable surgeon factors is needed.
