The Barretos short instrument for assessment of quality of life (BSIqol): development and preliminary validation in a cohort of cancer patients undergoing antineoplastic treatment

BACKGROUND

To be clinically useful, an instrument assessing health-related quality of life (HRQOL) should be easy to understand and quick to answer. Few instruments have been designed to be short, simple, and easily understandable by patients from all educational levels. The aim of the present study was to evaluate the psychometric properties of a brief general instrument developed to assess HRQOL.

METHODS

Results from a preliminary study regarding the initial development of the Barretos Short Instrument for Assessment of Quality of Life (BSIqol) with 80 cancer patients are presented. Out of all the patients, 59 completed the BSIqol on two occasions in order to evaluate the reproducibility test-retest. Validity analyses were done comparing scores from BSIqol with EORTC QLQ-C30 and Edmonton Symptom Assessment System (ESAS). In addition, BSIqol scores were analyzed in function of ECOG-PS, work activity, and financial income.

RESULTS

BSIqol demonstrated good internal consistency (Cronbach's α = 0.79) and adequate test-retest reliability, with intraclass coefficient correlation (ICC) varying from 0.736 to 0.946. There were adequate correlations between scores of BSIqol, EORTC QLQ-C30 and ESAS. The BSIqol was capable of discriminating between clinical subgroups, with different ECOG-PS and work activity. Patients completed the BSIqol in a median time <2 min. Only one patient reported some difficulty to answer the instrument.

CONCLUSIONS

BSIqol seems to be a straightforward and useful instrument for rapidly assessing HRQOL from cancer patients. Further studies are necessary to evaluate BSIqol in different populations and also to assess its responsiveness and define its minimal clinically important differences.

To Treat or Not to Treat? Dilemmas when Deciding on Antineoplastic Treatment in Patients With Far Advanced Cancers

Patients with advanced cancers and their oncologists are often faced with difficult treatment decisions, especially when there are borderline situations of expected benefit or increased risk of complications. In this narrative review, we will explore the decision-making process for patients with advanced cancers and provide insights on how to approach this complex task, while didactically dividing the oncologist's assessments according to a mnemonic rule of the ABCDE of therapeutic decision-making. Part A (advanced cancer) recalls that the rule is to be used specifically for advanced cancers. Parts B (potential benefits) and C (clinical conditions and risks) represents the traditional risk vs benefit scale. In Part D, we discuss ways to identify and understand patients' desires, values, preferences, and beliefs. The prognostic estimation, from Part E, may function as an "adjust" for the antineoplastic treatment decision-making. Treatment decisions need to be conducted by skilled oncologists, in a patient-centered care, aiming to promote valuable oncology with lower rates of aggressive care.

Health-Related quality of life by 31-item Cervantes scale in breast cancer survivors undergoing adjuvant endocrine therapy

INTRODUCTION

Instruments to manage adverse effects of endocrine therapy with Aromatase inhibitors (AI) may improve adherence and persistence to treatment and Health-Related Quality of Life (HRQL). The 31-item Cervantes Scale (CS-31) is an HRQL questionnaire with particularities of the perimenopausal and postmenopausal period that could be an appropriate instrument to assess HRQL in Breast Cancer (BC) survivors.

OBJECTIVE

This study aimed to perform additional validation of the CS-31 for BC survivors undergoing adjuvant endocrine therapy.

METHODS

This prospective study was performed at three time points named T0, T1, and T2: initial, intermediate, and final follow-up period, respectively, totaling 24 months of follow-up. At each time point, the participants completed the CS-31, Functional Assessment of Chronic Illness Therapy - Fatigue (FACIT-F), and Hospital Anxiety and Depression Scale (HADS). The internal consistency, construct validity, responsiveness analyses, and known-group validity of CS-31 were evaluated.

RESULTS

This study included 89 postmenopausal women diagnosed with hormone receptor-positive early BC in adjuvant endocrine therapy with AI. The internal consistency was good (Cronbach's alpha = 0.89). Construct validity received a positive rating, with 100% of results consistent with prior hypotheses. A prospective improvement in HRQL was identified for the CS-31 Global Score and FACIT-F Total Score and for most of their domains. Furthermore, women with anxiety and depression by HADS presented worse HRQL by CS-31.

CONCLUSION

The authors identified that the CS-31 seems to be appropriate for use in oncology medical routine and may help to monitor adverse effects and HRQL of BC survivors during adjuvant endocrine therapy.

Navigating Endocrine Sensitivity Assessment in Nonmetastatic Breast Cancer Through Early On-Treatment Ki67 Understanding

In the landscape of breast cancer management, precise assessment of endocrine sensitivity significantly influences therapeutic strategies. The utilization of Ki67, an immunohistochemical marker of tumor proliferation, in tumor rebiopsy holds paramount importance in unraveling breast cancer's response to endocrine therapy. This narrative review aims to elucidate the pivotal role of Ki67 in endocrine sensitivity assessment. We explore the nuanced process of Ki67 evaluation, its timing, and its implications for clinical outcomes in breast cancer patients. From a clinical perspective to pathological response and risk of recurrence, we navigate the spectrum of Ki67's impact. By delving into these facets, we underscore Ki67's potential to guide personalized treatment strategies, shedding light on the intricate interplay between endocrine therapy and clinical outcomes in breast cancer patients.

Dissecting the global leadership initiative on malnutrition criteria in advanced cancer: Reduced intake vs. inflammation

BACKGROUND & AIMS

The Global Leadership Initiative on Malnutrition (GLIM) criteria have been recommended for the diagnosis of malnutrition. It requires that the patient meets at least one phenotypic criterion and at least one aetiological criterion. For the latter, the patient must either demonstrate reduced food intake or have evidence of systemic inflammation. As both are common in advanced cancer, the aim of the present study was to determine, in patients who met the GLIM phenotypical criteria, which GLIM aetiological criteria (reduced food intake or systemic inflammation) is most useful in predicting overall survival (OS).

METHODS

Data from two cancer biobanks were combined. Inclusion criteria were: ≥18 years, advanced cancer (stage III or IV) and ability to provide written consent. Weight loss (WL) was selected as the phenotypic criterion of choice, as preliminary analysis demonstrated it to be a superior predictor of OS compared to body mass index. Malnutrition type 1 was defined as >5 % WL over 6 months and a C reactive protein (CRP) ≥3 mg/l. Further analysis was performed with a CRP >10 mg/l cut-off. Malnutrition type 2 was defined as >5 % WL over 6 months and reduced food intake, as reported in the Patient Generated Subjective Global Assessment. Survival was assessed using Kaplan-Meier methodology, log-rank tests and Cox proportional hazards models, with hazard ratios (HR) and confidence intervals (CI) reported.

RESULTS

In total, 176 patients were studied, with 147 events observed. The 3-month mortality rate was 32.4 % (CI: 25.1 to 39.0) and the 1-year mortality rate was 71.8 % (CI: 63.8 to 78.0). Malnutrition type 1 and malnutrition type 2 were observed in 37.8 % (HR: 2.27 [CI: 1.54 to 3.33], p < 0.001) and 26.3 % (HR: 1.74 [CI: 1.19 to 2.54], p = 0.005) of patients respectively, with both significantly increasing the risk of death. Following adjustment for relevant confounders both malnutrition type 1 (HR: 1.92 [CI: 1.25 to 2.94], p = 0.003) and malnutrition type 2 (HR: 1.61 [CI: 1.09 to 2.38], p = 0.019) remained significant predictors of OS. Median survival for patients with malnutrition type 1 was 2.14 (CI: 1.74 to 4.90) months compared to 9.5 (6.94-13.64) months for those without (p < 0.001). For malnutrition type 2, this was 2.37 (CI: 1.64 to 5.46) vs. 7.40 months (CI: 6.08 to 10.16), p = 0.004. When the CRP threshold was increased to >10 mg/l, malnutrition type 1 was observed in fewer patients (30.4%), median survival was shorter (1.91 [CI: 1.25 to 2.99] vs. 9.86 months [CI: 7.27 to 14.7], p < 0.001) and in both univariable (HR: 2.91 [CI: 1.94 to 4.63], p < 0.001) and multivariable (HR: 2.32 [CI: 1.50 to 3.60], p < 0.001) analyses, the risk of death increased.

CONCLUSION

The results suggest that the inflammatory component of GLIM appears superior compared to reduced intake in predicting OS and notably, a higher CRP threshold correlates with shorter OS. Therefore, whilst GLIM has multiple potential combinations, all treated with equal regard, these data suggest that the inflammatory aetiological component should be hierarchical to others.

Burial or cremation? Factors associated with preferences among patients with cancer in Brazil: a cross-sectional study

BACKGROUND

People living with life-limiting illnesses and their family caregivers consistently emphasize the importance of preparing for imminent death, with planned funerals being a common aspect of this preparation. Few studies have described the funeral rituals or post-mortem preferences of patients with cancer.

OBJECTIVE

To evaluate the percentage of patients with cancer who wish to be cremated and to identify the factors associated with this preference.

DESIGN AND SETTING

Cross-sectional study conducted at Barretos Cancer Hospital.

METHODS

A total of 220 patients with cancer completed a Sociodemographic and Clinical Questionnaire, the Duke University Religiosity Index, and burial or cremation preferences. Binary Logistic Regression was performed to identify independent variables associated with cremation.

RESULTS

Of the 220 patients, 25.0% preferred cremation and 71.4% preferred burial. Talks about death with family or close friends in their daily life (odds ratio, OR = 2.89; P = 0.021), patients that answered "other" (unsure, tends not be true and not true) for religious beliefs are what really lie behind my whole approach to life (OR = 20.34; P = 0.005), and education 9 to 11 years (OR = 3.15; P = 0.019) or ≥ 12 years (OR = 3.18; P = 0.024) were associated with cremation preference.

CONCLUSION

Most patients with Cancer in Brazil prefer burial after death. Discussions about death, religious beliefs and involvement, and educational level seem to influence the preference for cremation. A deeper understanding of ritual funeral preferences and their associated factors may guide policies, services, and health teams in promoting the quality of dying and death.

Biologically based therapies are commonly self-prescribed by Brazilian women for the treatment of advanced breast cancer or its symptoms

PURPOSE

Breast cancer (BC) might be associated with loss of function in affected patients, with a direct impact on their quality of life (QOL). Many women with metastatic BC seek relief of symptoms, including the use of complementary and alternative medicine (CAM) to cure cancer. The present study aimed to identify the pattern of CAM used by patients with metastatic BC and to assess the correlation between CAM use and scores on anxiety, depression, and QOL scales.

METHODS

A total of 126 women with metastatic BC were interviewed using four instruments: (1) a questionnaire containing socioeconomic, clinical, and demographic data and CAM use; (2) European Organization for Research and Treatment of Cancer Core Quality of Life Questionnaire (EORTC QLQ)-C30; (3) EORTC QLQ-BR23; and (4) the Hospital Anxiety and Depression Scale.

RESULTS

Fifty percent of the participants reported the use of at least one CAM modality. Biologically based practices were the most frequently used to treat BC and/or its symptoms, the most commonly discussed with the oncologists, and one of the CAM categories in which more patients reported a desire to learn more about. The overall use of CAM was not correlated with the scores on the anxiety, depression, and QOL scales. However, analysis of the association of the QOL scores with specific CAM modalities revealed some potential associations (especially for food supplements, art therapy, psychotherapy, and prayer).

CONCLUSIONS

Women with metastatic BC frequently make use of CAM to treat the cancer and/or its symptoms. Biologically based practices seem to be particularly important in Brazil. An association between specific CAM modalities and some QOL domains was suggested, but it needs further confirmation.

Go Wish card game-exploring end-of-life wishes of patients in oncology palliative care: a qualitative study

BACKGROUND

Among the methods that promote quality of life and care, discussing and remembering end-of-life (EOL) wishes for future care may contribute to decision-making about care and the promotion of a good death. Our aim was to investigate the most significant EOL desires among Brazilian cancer patients receiving palliative care (PC).

METHODS

This was an exploratory, descriptive, and qualitative study conducted in a Palliative Care Oncology Unit. Fifteen patients played the Go Wish card game (GWCG), choosing and categorizing cards into themes as very important, more or less important, and not important at all. The ten most important cards were discussed, and categories were defined for each card. Cards with the highest frequencies of choice were described. Patients were also asked, "What did playing the cards mean to you?". All data were analyzed using Bardin's content analysis and generated a word cloud to interpret the participants' narratives.

RESULTS

Out of the 36 cards, card 19, "I want my family and friends close to me", was the most frequently chosen. Out of the 15 patients studied, only one reported that they initially did not enjoy playing the cards. In this study, the GWCG was effective in fulfilling 90% of the patients' wishes, and this was only possible with the support of the researchers, members of the multi-professional team, and patients' families.

CONCLUSIONS

The use of the GWCG in the oncology PC setting made an important contribution to open discussions about patients' values and preferences, as well as being an easy-to-use, understandable, and flexible tool. Prioritizing the fulfillment of patients' wishes was one of the main strengths of this study. Our study suggests working with these wishes as a framework for person-centered care.

Translation and cultural adaptation of the Breast Cancer Treatment Outcome Scale (BCTOS) into Brazilian Portuguese

BACKGROUND

Breast conservative treatment (BCT) is safe when it is performed in association with radiotherapy. The number of referral for BCT has increased, and it has become an important treatment modality. Patients who undergo BCT present some characteristics that are associated with better quality of life compared with patients who undergo mastectomy without reconstruction. Instruments that measure the quality of life specifically used in cases of BCT are limited. One of these instruments is the Breast Cancer Treatment Outcome Scale (BCTOS), which has not yet been translated into Brazilian Portuguese. It contains 22 questions and four domains (functional, aesthetic, breast sensitivity and oedema).

METHODS

We performed the translation and cultural adaptation process using Beaton's and EORTC translations process. In summary, the translation process is based on Portuguese translation, translation summary, reverse translation into English, expert committee, pre-test (10 patients), questionnaire review and test of the final version (6 patients).

RESULTS

All 16 patients were submitted to quadrantectomy and mammary radiotherapy. Lymphedema was present in 4, altered strength in 5, and altered shoulder mobility in 6 patients. Considering the questionnaire, the reconciled version determined change in 2 items. Pre-test evaluation showed difficulties in 3 patients, but the questionnaire did not change. Test evaluation showed no problems.

CONCLUSION

The translation of BCTOS into Portuguese will help us to evaluate the quality of life in BCT patients evaluating treatment-related sequelae and may be useful for oncoplastic surgery evaluation.

Go Wish Card Game for Meaningful Conversations in the Oncology Healthcare Context: A Narrative Review

The Go Wish Card Game (GWCG) is emerging as a valuable tool for facilitating end-of-life (EoL) discussions, particularly in oncology care where patients face complex treatment decisions. This review investigates the GWCG's intended use, its application in oncology settings, and best practices for introducing it to patients. It also addresses the challenges and barriers to its implementation in clinical practice. A search for scientific evidence revealed a significant gap in the literature: while various sources, including qualitative studies and reviews, were reviewed, only a small portion focused on intervention outcomes. This underscores the need for more comprehensive studies to evaluate the GWCG's effectiveness, especially in EoL care. Despite its potential to foster meaningful conversations and support informed decision-making, successful implementation requires overcoming barriers such as patient resistance and the need for a sensitive, gradual approach to EoL topics. Further research, particularly clinical trials, is essential to confirm its broader applicability and effectiveness.

Pharmacologic Management of End-of-Life Delirium: Translating Evidence into Practice

End-of-life delirium affects a vast majority of patients before death. It is highly distressing and often associated with restlessness or agitation. Unlike delirium in other settings, it is considered irreversible, and non-pharmacologic measures may be less feasible. The objective of this review is to provide an in-depth discussion of the clinical trials on delirium in the palliative care setting, with a particular focus on studies investigating pharmacologic interventions for end-of-life delirium. To date, only six randomized trials have examined pharmacologic options in palliative care populations, and only two have focused on end-of-life delirium. These studies suggest that neuroleptics and benzodiazepines may be beneficial for the control of the terminal restlessness or agitation associated with end-of-life delirium. However, existing studies have significant methodologic limitations. Further studies are needed to confirm these findings and examine novel therapeutic options to manage this distressing syndrome.

Where do Brazilian cancer patients prefer to die? Agreement between patients and caregivers

Preferred place-of-death (PPoD) is considered an important outcome for the development of appropriate models of care and for improving health policies in countries with underdeveloped palliative care (PC) OBJECTIVES: To determine the concordance between the PPoD of a sample of Brazilian seriously-ill cancer patients and their caregivers, and its associated factors under four different end-of-life (EOL) scenarios: 1) health deterioration in the overall context; 2) health deterioration with severe and uncomfortable symptoms; 3) health deterioration receiving home-based visits as needed; 4) health deterioration receiving home-based visits as needed, when suffering severe and uncomfortable symptoms METHODS: Cross-sectional study at a large Brazilian cancer center, between February 2019 and July 2021. 190 adult cancer patients and their caregivers (n = 190) were analyzed RESULTS: Patient and/or caregiver PPoD concordance for EOL scenario one: 64% vs. 43% for death at home, 22% vs. 30% for death in a PC unit, 14% vs. 27% for death in hospital. Higher patient and/or caregiver PPoD concordance was found for death in hospital (41%; 49%) in EOL scenario two, and for death at home for scenario three (77%; 74%). Agreement coefficient was moderate for scenario two (k = 0.430; P < 0.001), and fair for EOL scenarios one, three and four (k = 0.237, P < 0.001; k = 0.296, P < 0.001; k = 0.307, P < 0.001, respectively). Associated disagreement factors were: performance status (OR:3.03), self-perceived health (OR: 6.99), marital status (OR:2.92), and hospital and/or emergency room proximity (OR:4.11). The presence of relevant persons (42.3% vs. 44.2%), followed by spirituality (38.5% vs. 27.9%) and the place-of-death (14.0% vs. 18.4%), were the most important factors in the EOL, when comparing patients and care givers opinions, respectively CONCLUSION: Low agreement between patients and caregivers on PPoD was identified. EOL clinical factors and deterioration, and PC support seem to influence PPoD.

Translation, Validity and Internal Consistency of the Quality of Dying and Death Questionnaire for Brazilian families of patients that died from cancer: a cross-sectional and methodological study

BACKGROUND

The Quality of Dying and Death Questionnaire (QoDD) may prove to be an important evaluation tool in the Brazilian context, and, therefore, can contribute to a more precise evaluation of the dying and death process, improving and guiding the end-of-life patient care.

OBJECTIVE

To translate and cross-culturally adapt the QoDD into Brazilian Portuguese and measure its validity (convergent and known-groups) and internal consistency.

DESIGN AND SETTING

A cross-sectional, methodological study was conducted at the Hospital de Câncer de Barretos, Brazil.

METHODS

A total of 78 family caregivers participated in this study. Semantic, cultural, and conceptual equivalences were evaluated using the content validity index. The construct validity was assessed through convergent validation and known groups analysis [presence of family members at the place of death; feel at peace with dying; and place of death (hospital versus home; hospital versus Palliative Care)]. Internal consistency was evaluated using Cronbach's alpha.

RESULTS

The questionnaire was translated into Brazilian Portuguese and presented evidence of a clear understanding of its content. Cronbach's alpha values were ≥ 0.70, except for the domains of treatment preference (α = 0.686) and general concerns (α = 0.599). The convergent validity confirmed a part of the previously hypothesized correlations between the Palliative Care Outcome Scale-Brazil (POS-Br) total scores and the QoDD domain scores. The QoDD-Br domains could distinguish the patients who died in palliative care and general wards.

CONCLUSION

The QoDD-Br is a culturally adapted valid instrument, and may be used to assess the quality of death of cancer patients.

Impact of Preoperative Counseling and Education on Decreasing Anxiety in Patients With Gynecologic Tumors: A Randomized Clinical Trial

OBJECTIVE

To evaluate the impact of counseling and preoperative education on reducing anxiety in patients undergoing surgery for gynecologic cancer.

METHODS

In this randomized clinical trial, patients with gynecological tumors undergoing surgical treatment between 15 and 60 days preoperatively, were included. The group was randomized to receive preoperative routine orientation plus preoperative counseling and education by nursing (experimental group [EG]) or receive preoperative routine orientation only (control group [CG]). We stratified the groups by surgical approach: open, laparoscopy, and robotic. We excluded patients treated in another service and with the need for an intensive care unit after surgery. We used the Hospital Anxiety and Depression Scale (HADS) to evaluate symptoms of anxiety and depression. The severity of symptoms was evaluated using the Edmonton Symptom Assessment System (ESAS-Br).

RESULTS

We analyzed 54 women (CG 27, EG 27). No significant differences were observed regarding ESAS scores (total, physical, emotional, well-being, and anxiety) between preoperative and postoperative evaluation. However, in the EG, comparing the preoperative versus postoperative moments, there was a significant reduction in total, emotional, and anxiety scores of ESAS (p = 0.012; p = 0.003; p = 0.001). No difference in anxiety symptoms by HADS scale was noted between the two groups, comparing preoperative and postoperative moments, CG (40.7% and 22.2%) and EG (37.0% and 25.9%) (p = 0.78; p = 0.75), respectively. Also, in depression symptoms (HADS scale), we found no difference comparing preoperative and postoperative moments (p = 0.34; p > 0.99). When we stratified by surgical approach or time between intervention and surgery ( ≤ 15, > 15 to ≤ 30, and > 30 days), no difference was observed in the anxiety and depression symptoms evaluation, in both groups.

CONCLUSIONS

The preoperative education by nurse orientation reduced the total, emotional, and anxiety symptoms of ESAS score between preoperative and postoperative moments. However, by the HADS scale, there was no difference in anxiety and depression symptoms.

Exploring patient awareness of palliative care - optimal timing and preferred approaches

OBJECTIVES

To explore patients' awareness levels of palliative care (PC) and how this awareness shapes their preferences regarding the timing and approach for discussing it.

METHODS

The study, conducted at a prominent institution specializing in oncology care, enrolled women aged 18-75 years who had been diagnosed with breast cancer. Patients completed guiding questions: Do you know what PC is?, When is the most appropriate time and the most appropriate way to discuss PC?. The interviews were conducted exclusively via video call and were recorded, transcribed, and then deleted.

RESULTS

The study involved 61 participants, averaging 49 years old. Almost half (47.5%) had completed high school. Qualitative data analysis revealed 9 thematic categories. Regarding the first question, 2 divergent categories emerged: care for life and threatening treatment. For the second question, opinions diverged into 4 categories: At an early stage, mid-course of the disease, as late as possible, and no time at all. For the third question, 3 categories emerged: communication and support, care setting and environment, and improving the PC experience.

SIGNIFICANCE OF RESULTS

This study reveals diverse perspectives on patients' awareness and preferences for discussing PC, challenging the misconception that it's only for end-of-life (EOL) situations. Comprehending PC influences when and how patients discuss it. If tied solely to EOL scenarios, discussions may be delayed. Conversely, understanding its role in enhancing advance support encourages earlier conversations. Limited awareness might delay talks, while informed patients actively contribute to shared decision-making. Some patients prefered early involvement, others find mid-treatment discussions stress-relieving. Community support, quiet environments, and accessible resources, underscoring the importance of a calm, empathetic approach, emphasizing the importance of understanding its role in advance support and providing valuable implications for enhancing patient care practices, theories, and policies.

The palliative care triage system in advanced cancer emergency care: development and initial validation

OBJECTIVE

We aimed to develop and validate a new emergency triage tool for use on patients with cancer undergoing palliative care (PC).

METHODS

In phase I, the new tool was developed after literature review and expert committee meetings. A prospective longitudinal study in phase II assessed the interobserver reliability of the tool. In phase III, a retrospective study of administrative data, the feasibility of routine use of the new tool and the associations with hospitalisation and survival times were evaluated.

RESULTS

The palliative care triage system (PCTS) was composed of check-list items and four colour-coded categories for maximum response time. In phase II, the PCTS was independently evaluated by two nurses for 102 attendances in the emergency department of the PC unit. An absolute agreement of 87.3% and a weighted kappa of 0.81 were observed. In phase III, all 493 attendances had the PCTS assessment registered in the medical records. The PCTS categories were associated with hospital admission (p<0.001) and survival times (p<0.001).

CONCLUSION

PCTS is a feasible tool to be used in routine ED triage of patients with advanced cancer undergoing PC. It is a valid instrument for predicting hospital admission rates and survival with high interobserver concordance rates.

The Magee 3 Equation Predicts Favorable Pathologic Response to Neoadjuvant Endocrine Therapy in Breast Cancer Patients

BACKGROUND

Breast cancer (BC) remains a significant health care challenge, and treatment approaches continue to evolve. Among these, neoadjuvant endocrine therapy (NET) has gained prominence, particularly for postmenopausal, hormone-receptor positive, HER2-negative (HR+/HER2-) BC patients. Despite this, a significant gap exists in identifying patients who stand to benefit from NET. The objective of this study was to assess whether Magee equations (MEs) could serve as predictors of response to NET.

METHODS

This retrospective study included adult patients with invasive BC who underwent NET followed by curative surgery. Assessment of sociodemographic, clinical, and tumor-related variables was conducted. The ME1, ME2, ME3, and ME mean were analyzed to explore their predictive role for NET response. Receiver operating characteristic (ROC) curves were employed, along with the determination of optimal cutoff points. Logistic regression models were utilized to identify the most significant predictors of pathological response.

RESULTS

Among the 75 female participants, the mean age was 69.4 years, with the majority being postmenopausal (n = 72, 96%) and having an ECOG-PS of 0/1 (n = 63, 84%). Most patients were classified as luminal A (n = 41, 54.7%). ME3 emerged as a promising predictor, boasting an AUC of 0.734, with sensitivity of 90.62% and specificity of 57.50% when the threshold was ≤ 19.97. In univariate analysis, clinical staging (p = 0.002), molecular subtype (p = 0.001), and ME3 (continuous = 0.001, original 3-tier: p = 0.013, new 2-tier: <0.001) categories exhibited significant associations with pathological response. In the multivariate model, clinical staging and new 2-tier ME3 (<20 vs. ≥20) were included as significant variables.

CONCLUSIONS

Patients with ME3 < 20 have a higher likelihood of presenting a pathological response, offering a cost-effective alternative tool to Oncotype DX. Larger future studies with a prospective design are awaited to confirm our findings.

Challenging Rationality: Examining the Belief in Cure Among Patients With Advanced Incurable Cancers

Citing a recently published study, this letter to the editor highlights again the critical role of prognostic awareness in the decision-making process for cancer therapeutics.

Adherence to Adjuvant Endocrine Therapy in Patients With Nonmetastatic Estrogen Receptor-Positive Breast Cancer: A Comprehensive Brazilian Real-World Data Study

PURPOSE

Adjuvant endocrine therapy (ET) improves the prognosis of patients with nonmetastatic estrogen receptor-positive (ER+) breast carcinoma; however, adherence is crucial to ensure its efficacy. In Brazil, data regarding adherence to ET are limited. We aimed to evaluate the adherence to ET across Brazil and the characteristics associated with adherence.

METHODS

Women with nonmetastatic ER+ invasive breast carcinoma who underwent ET for at least 6 months were enrolled. Adherence was assessed using the Morisky Medication Adherence Scale-8 (MMAS-8) and defined as an MMAS-8 score of 8. The groups were compared using the chi-square or exact chi-square tests for qualitative variables and the nonparametric Mann-Whitney test for quantitative variables.

RESULTS

Between June 2021 and September 2023, 726 patients were included in this analysis. The adherence to ET was 58.7%. The median age of the adherent women was higher than that of the nonadherent women (58.3 years v 54.8 years; P = .009). Factors associated with adherence were nonuse of ovarian suppression (P = .004), use of anti-human epidermal growth factor receptor 2 therapy (P = .007), high European Organisation for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire C30 scores on global health status (P = .0004), role functioning (P = .03), emotional functioning (P = .0007), cognitive functioning (P < .001), and social functioning (P = .0005), and EORTC BR23 scores on body image (P < .001) and future perspective domains (P = .0198).

CONCLUSION

More than one third of the patients evaluated were not adherent to ET. Although the study did not assess the impact of interventions to improve adherence to adjuvant ET, the 58.7% adherence rate shows that this study is of utmost importance.

Discrepancies in breast cancer's oncological outcomes between public and private institutions in the southeast region of Brazil: a retrospective cohort study

BACKGROUND

Brazil is a middle-income country with inequalities in its healthcare system. The disparities between public and private services affect the diagnosis and treatment of patients with breast cancer. The aim of this study is to assess whether disease-free survival (DFS) and overall survival (OS) are different in public and private specialized centers.

PATIENT AND METHODS

A retrospective cohort study with 1,545 breast cancer patients diagnosed from 2003 to 2011 at Barretos Cancer Hospital-BCH (public group, N = 1,408) and InORP Oncoclinicas (private group, N = 137) was conducted. A 1:1 propensity score matching (PSM) analysis was used to adjust the differences between the groups' characteristics (n = 137 in each group).

RESULTS

The median age at diagnosis was 54.4 years. Estimated DFS rates at 1, 5, and 10 years were 96.0%, 71.8%, and 59.6%, respectively, at BCH and 97.8%, 86.9%, and 78%, respectively, at InORP (HR: 2.09; 95% confidence interval [CI], 1.41-3.10; p < 0.0001). Estimated OS rates at 1, 5, and 10 years were 98.1%, 78.5%, and 65.4%, respectively, at BCH and 99.3%, 94.5%, and 91.9%, respectively, at InORP (HR: 3.84; 95% CI, 2.16-6.82; p < 0.0001). After adjustment by PSM, DFS and OS results in 1, 3, and 5 years remained worse in the public service compared to the private service.

CONCLUSION

Patients treated in a public center have worse DFS and OS after a follow-up period of more than 5 years. These results were corroborated after carrying out the PSM.
