Dynamics of Long-Term Patient-Reported Quality of Life and Health Behaviors After Adjuvant Breast Cancer Chemotherapy

Pooled analysis of NeoCARH and NeoCART trials: patient-reported outcomes in patients with early-stage breast cancer receiving platinum-based or anthracycline-based neoadjuvant chemotherapy

PURPOSE

Anthracycline-based or platinum-based neoadjuvant chemotherapy belongs to the standard treatment for early-stage breast cancer (EBC) that is either triple-negative or human epidermal growth factor receptor 2 positive (HER2 +). Currently, there is a paucity of data comparing their impact on health-related quality of life (HRQoL).

METHODS

Triple-negative or HER2 + EBC from our two prospective randomized controlled trials, neoCARH and neoCART, were divided into two groups based on the neoadjuvant chemotherapy regimens they received: anthracycline-based or platinum-based group. HRQoL was the exploratory endpoint in these two trials, which was assessed using the European Organization for Research and Treatment of Cancer Quality of Life-Core30 and Breast23 questionnaires. The primary variable of interest was the C30 summary score (C30-SumSc). Assessments were carried out at baseline, after neoadjuvant chemotherapy, and 1 year and 2 years after diagnosis.

RESULTS

The mean questionnaires' compliance rate was 95.0%. After neoadjuvant chemotherapy, 210 patients had evaluable HRQoL data, the mean least square change from baseline for the platinum-based group was - 15.997 (95% confidence interval (CI): - 17.877 to - 14.117), and it was - 20.156 (95% CI: - 22.053 to - 18.258) for the anthracycline-based group (difference: 4.159, 95% CI: 1.462 to 6.855, P = 0.003, minimal important difference = 3). For the majority of the domains of interest assessed by the C30 and BR23 questionnaires, the platinum-based group demonstrated superior outcomes in comparison to the anthracycline-based group.

CONCLUSION

Patients receiving platinum-based or anthracycline-based regimens both experienced worsened HRQoL after neoadjuvant chemotherapy; however, the former provided relatively better HRQoL compared with the latter.

An effort to improve the collection of patient-generated data: readability and understandability of patient-reported outcomes measures in a survivorship cohort

PURPOSE

In this study, we evaluated readability and understandability of nine French-language Patient-Reported Outcome Measures (PROMs) that are currently used in a contemporary longitudinal cohort of breast cancer survivors as part of an effort to improve equity in cancer care and research.

METHODS

Readability of PROMs was assessed using the Flesh Reading Ease Score (FRES), the Gunning's Fog Index (FOG), and the FRY graphics. Readability was considered ideal if mean score ≤ 6th-grade level and acceptable if between 6th and 8th grade. Understandability was evaluated using the Patient Education Materials Assessment Tool and defined as ideal if PEMAT ≥ 80%. The Evaluative Linguistic Framework for Questionnaires (ELF-Q) provided additional qualitative elements to assess understandability. Plain-language best practice was met if both readability and understandability were ideal.

RESULTS

None of the 9 PROMs evaluated had ideal readability scores and only 1 had an acceptable score. Understandability ranged from 55% to 91%, and only 3 PROMs had ideal scores. ELF-Q identified points for improvement in several understandability dimensions of the PROMs. None of the instruments met the definition of plain-language best practice.

CONCLUSION

None of the studied PROMs met the standards of readability and understandability. Future development and translation of PROMs should follow comprehensive linguistic and cultural frameworks to ensure plain-language standards and enhance equitable patient-centered care and research.

Patient-Reported Outcomes in OlympiA: A Phase III, Randomized, Placebo-Controlled Trial of Adjuvant Olaparib in gBRCA1/2 Mutations and High-Risk Human Epidermal Growth Factor Receptor 2-Negative Early Breast Cancer

PURPOSE

The OlympiA randomized phase III trial compared 1 year of olaparib (OL) or placebo (PL) as adjuvant therapy in patients with germline BRCA1/2, high-risk human epidermal growth factor receptor 2-negative early breast cancer after completing (neo)adjuvant chemotherapy ([N]ACT), surgery, and radiotherapy. The patient-reported outcome primary hypothesis was that OL-treated patients may experience greater fatigue during treatment.

METHODS

Data were collected before random assignment, and at 6, 12, 18, and 24 months. The primary end point was fatigue, measured with the Functional Assessment of Chronic Illness Therapy-Fatigue scale. Secondary end points, assessed with the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire, Core 30 item, included nausea and vomiting (NV), diarrhea, and multiple functional domains. Scores were compared between treatment groups using mixed model for repeated measures. Two-sided P values <.05 were statistically significant for the primary end point. All secondary end points were descriptive.

RESULTS

One thousand five hundred and thirty-eight patients (NACT: 746, ACT: 792) contributed to the analysis. Fatigue severity was statistically significantly greater for OL versus PL, but not clinically meaningfully different by prespecified criteria (≥3 points) at 6 months (diff OL v PL: NACT: -1.3 [95% CI, -2.4 to -0.2]; P = .022; ACT: -1.3 [95% CI, -2.3 to -0.2]; P = .017) and 12 months (NACT: -1.6 [95% CI, -2.8 to -0.3]; P = .017; ACT: -1.3 [95% CI, -2.4 to -0.2]; P = .025). There were no significant differences in fatigue severity between treatment groups at 18 and 24 months. NV severity was worse in patients treated with OL compared with PL at 6 months (NACT: 6.0 [95% CI, 4.1 to 8.0]; ACT: 5.3 [95% CI, 3.4 to 7.2]) and 12 months (NACT: 6.4 [95% CI, 4.4 to 8.3]; ACT: 4.5 [95% CI, 2.8 to 6.1]). During treatment, there were some clinically meaningful differences between groups for other symptoms but not for function subscales or global health status.

CONCLUSION

Treatment-emergent symptoms from OL were limited, generally resolving after treatment ended. OL- and PL-treated patients had similar functional scores, slowly improving during the 24 months after (N)ACT and there was no clinically meaningful persistence of fatigue severity in OL-treated patients.

Managing menopause after cancer

Globally, 9 million women are diagnosed with cancer each year. Breast cancer is the most commonly diagnosed cancer worldwide, followed by colorectal cancer in high-income countries and cervical cancer in low-income countries. Survival from cancer is improving and more women are experiencing long-term effects of cancer treatment, such as premature ovarian insufficiency or early menopause. Managing menopausal symptoms after cancer can be challenging, and more severe than at natural menopause. Menopausal symptoms can extend beyond hot flushes and night sweats (vasomotor symptoms). Treatment-induced symptoms might include sexual dysfunction and impairment of sleep, mood, and quality of life. In the long term, premature ovarian insufficiency might increase the risk of chronic conditions such as osteoporosis and cardiovascular disease. Diagnosing menopause after cancer can be challenging as menopausal symptoms can overlap with other common symptoms in patients with cancer, such as fatigue and sexual dysfunction. Menopausal hormone therapy is an effective treatment for vasomotor symptoms and seems to be safe for many patients with cancer. When hormone therapy is contraindicated or avoided, emerging evidence supports the efficacy of non-pharmacological and non-hormonal treatments, although most evidence is based on women older than 50 years with breast cancer. Vaginal oestrogen seems safe for most patients with genitourinary symptoms, but there are few non-hormonal options. Many patients have inadequate centralised care for managing menopausal symptoms after cancer treatment, and more information is needed about cost-effective and patient-focused models of care for this growing population.

Longitudinal patterns of patient-reported sleep disturbances after surgery for lung cancer

PURPOSE

The purpose of this study was to identify longitudinal heterogeneous trajectories of sleep status, adjusted for the effect of pain over time, among patients who had surgery for lung cancer and to quantify how disturbed sleep in the hospital affects functional recovery after discharge.

METHODS

We included patients from a surgical cohort (CN-PRO-Lung 1). All patients reported symptoms using the MD Anderson Symptom Inventory-Lung Cancer (MDASI-LC) daily during postoperative hospitalization. Group-based dual trajectory modeling was used to investigate trajectories of disturbed sleep and pain during the first 7 days of postoperative hospitalization. Cox regression was used to compare the recovery of walking ability between the different sleep trajectories.

RESULTS

Among 421 patients, disturbed sleep trajectories comprised low (31%), moderate (52%), and high (17%) groups. The surgical approach and number of chest tubes were associated with pain, and the number of chest tubes was also associated with sleep disturbances (OR = 1.99; 95% CI: 1.08-3.67). Recovery of walking ability after discharge was significantly slower in the high (median days = 16; 95% CI: 5-NA) and moderate disturbed sleep trajectory groups (median days = 5; 95%CI: 4-6) than in the low group (median days = 3; 95% CI: 3-4).

CONCLUSION

Changes in disturbed sleep among patients with lung cancer followed three distinct trajectories over the first 7 days of hospitalization after surgery. Dual trajectory analyses highlighted the high concordance between specific trajectories of disturbed sleep and pain. Patients at high sleep disturbance and high levels of pain may benefit from appropriate interventions for both symptoms in combination with the patient's surgical approach and the number of chest tubes.

Obesity correlates with the immunosuppressive ILC2s-MDSCs axis in advanced breast cancer

AIM

We investigated the relationship between the group 2 innate lymphoid cells (ILC2s)-myeloid-derived suppressor cells (MDSCs) axis and obesity-related breast cancer.

METHODS

Fifty-eight patients with breast cancer who had first relapse and metastasis between January 2019 and August 2021 were enrolled. The proportions of ILC2s and MDSCs in blood and the levels of cytokines in serum were detected with flow cytometry. Correlation analysis among clinical characteristics (such as body mass index [BMI]), cytokines, ILC2s, and MDSCs was conducted.

RESULTS

There was a significant difference in the proportions of ILC2s and MDSCs between the high BMI group and the normal BMI group (p < .05). In the triple-negative breast cancer (TNBC) patients, the proportions of ILC2s and MDSCs in the obese group were significantly higher than those in the nonobese group (p < .05). In all breast cancer patients, there was a positive correlation between BMI and the ILC2s-MDSCs axis (p < .05). However, there was no correlation observed between the number of metastases, progression-free survival, and the ILC2s-MDSCs axis (p > .05). Additionally, ILC2s showed positive correlations with MDSCs, interleukin-5 (IL-5), IL-10, IL-17A, (PD-L1), programmed cell death 2 ligand 2 (PD-L2), and molecular typing (p < .05). Similarly, MDSCs exhibited positive correlations with IL-5, IL-8, IL-9, IL-17A, PD-L1, and PD-L2 (p < .05). In patients with TNBC, there was a positive correlation between BMI and IL-5 (p < .05).

CONCLUSION

Conclusively, obesity may enhance the immunosuppressive effect of the ILC2-MDSC axis in advanced breast cancer. IL-5 may play a vital role in the ILC2-MDSC axis and obesity in TNBC.

Patient-Reported Quality of Life 6 Years After Breast Cancer

This cohort study assesses quality-of-life trajectories up to 6 years after breast cancer diagnosis among individuals in France.

Machine learning-derived model for predicting poor post-treatment quality of life in Korean cancer survivors

PURPOSE

A substantial number of cancer survivors have poor quality of life (QOL) even after completing cancer treatment. Thus, in this study, we used machine learning (ML) to develop predictive models for poor QOL in post-treatment cancer survivors in South Korea.

METHODS

This cross-sectional study used online survey data from 1,005 post-treatment cancer survivors in South Korea. The outcome variable was QOL, which was measured using the global QOL subscale of the European Organization of Cancer and Treatment for Cancer Quality of Life Questionnaire, where a global QOL score < 60.4 was defined as poor QOL. Three ML models (random forest (RF), support vector machine, and extreme gradient boosting) and three deep learning models were used to develop predictive models for poor QOL. Model performance regarding accuracy, area under the receiver operating characteristic curve, F1 score, precision, and recall was evaluated. The SHapely Additive exPlanation (SHAP) method was used to identify important features.

RESULTS

Of the 1,005 participants, 65.1% had poor QOL. Among the six models, the RF model had the best performance (accuracy = 0.85, F1 = 0.90). The SHAP method revealed that survivorship concerns (e.g., distress, pain, and fatigue) were the most important factors that affected poor QOL.

CONCLUSIONS

The ML-based prediction model developed to predict poor QOL in Korean post-treatment cancer survivors showed good accuracy. The ML model proposed in this study can be used to support clinical decision-making in identifying survivors at risk of poor QOL.

Omission of radiation therapy after breast-conserving surgery for biologically favourable tumours in younger patients: The wrong answer to the right question

In this perspective paper, the findings of the recently published LUMINA study are critically evaluated, with an emphasis on the need for careful interpretation and a thoughtful approach in clinical practice. The LUMINA trial, which investigates the role of adjuvant endocrine therapy in low-risk breast cancer patients, is assessed for its limitations, including a highly selective patient cohort and an insufficient follow-up period. The importance of long-term data and further trials to inform clinical decisions effectively is emphasized. While the LUMINA study does not support an immediate change in practice, it is seen as a foundation for generating hypotheses to guide ongoing clinical trials. This important study has served as inspiration to develop this perspective paper, which takes into account ongoing studies and the toxicity profile of postoperative treatments in low-risk recurrence breast cancer. The need for a patient-cantered approach is stressed, considering individual wishes and desires in decision-making, despite the complexity of articulating these aspects in guidelines. A wise interpretation of available findings is essential to ensure sound clinical decision-making before broadly applying omission of radiation therapy.

LUMINA: Using molecular biomarkers to guide decision making for breast radiotherapy

In this opinion piece, we respond to comments about the LUMINA trial by Meattini and colleagues in the Journal. LUMINA was a prospective cohort study which evaluated the omission of radiotherapy after breast conserving surgery (BCS) in patients treated with endocrine therapy with low risk clinico-pathologic features and luminal A breast cancer. We address their areas of concern including the single cohort design that required careful patient selection, the relatively short follow-up period of 5 years, and the limited follow-up on younger patients. The Ki67 biomarker was key to defining the luminal A phenotype. We clarify the evidence supporting the Ki67 criteria used. The compliance with endocrine therapy was high and similar to other contemporary trials. Based on the results of LUMINA, and mounting evidence from other trials, we feel comfortable offering our patients the option of no radiotherapy after BCS if they fit the trial eligibility criteria from LUMINA and have decided to receive adjuvant endocrine therapy. We concur that a patient-centered approach to treatment decision making should be used to make patients aware of all available information including the results of the LUMINA trial when deciding on post-operative breast radiotherapy.

Factors Associated with Poor Quality of Life in Breast Cancer Survivors: A 3-Year Follow-Up Study

The purpose of this study was to identify subgroups of quality of life (QOL) changes in breast cancer survivors (BCSs), and to determine factors associated with subgroups of consistently low or deteriorated QOL. We enrolled 101 women recently diagnosed with breast cancer in South Korea and asked them to complete a questionnaire at baseline (within 1 month of diagnosis), 1 year later (Year 1), 2 years later (Year 2), and 3 years later (Year 3). We assessed QOL using the global QOL subscale from the EORTC QLQ-C30. We defined low QOL as a global QOL score 10 points below the mean score of the general population. Based on low QOL as defined in this study, we identified subgroups of QOL changes over 3 years. We identified four subgroups of QOL changes: improved (47.4%), stable (30%), continuously low (8.8%), and deteriorated (13.8%), and considered the last two categories (22.6%) poor QOL. Logistic regression analyses demonstrated that significant determinants of poor QOL were insomnia at Year 1, fatigue and anxiety at Year 2, and fatigue, depression, and comorbidity at Year 3. In conclusion, persistent symptoms of insomnia, fatigue, anxiety, depression, and comorbidity are potential risk factors for poor QOL in BCSs.

The mediating role of cognitive emotion regulation in the relationship between self-concealment and quality of life among breast cancer chemotherapy patients

PURPOSE

This study aimed to explore whether self-concealment (SC) affects the quality of life (QOL), and whether cognitive emotion regulation (CER) mediates the relationship between SC and QOL among breast cancer chemotherapy patients.

METHODS

This cross-sectional study was conducted among 228 breast cancer chemotherapy patients from November 2021 to March 2022 in Anhui Province, China. Data were collected using the Self-Concealment Scale, Cognitive Emotion Regulation Questionnaire, and Short Form 36 Questionnaire. Descriptive statistics, independent-sample t test, one-way analysis of variance, and structural equation modeling were used to explore associations among SC, CER, and QOL.

RESULTS

QOL levels differed significantly by participant age, monthly per capita household income and home location. SC was negatively correlated with QOL. SSC was negatively correlated with adaptive-CER strategies and positively correlated with maladaptive-CER strategies. Adaptive-CER strategies were positively correlated with QOL. Maladaptive-CER strategies were negatively correlated with QOL. CER fully mediated the association between SC and QOL in breast cancer chemotherapy patients.

CONCLUSION

Nursing staff should help breast cancer chemotherapy patients reduce the use of maladaptive-CER strategies in the care of patients in the future. Helping patients reduce SC is more conductive to improving the QOL of breast cancer chemotherapy patients.

A qualitative study on the healthcare experiences of adolescents and young adults (AYA) with an uncertain or poor cancer prognosis

PURPOSE

Treatment advancements have improved life expectancy for adolescents and young adults (AYAs) with an uncertain and/or poor cancer prognosis (UPCP) and change clinical practice. This improved survival requires a different approach and specific expertise to meet the needs of this group. The aim of this study is to explore the health care experiences of AYAs with a UPCP.

METHODS

We conducted a multicenter qualitative study using semi-structured interviews and elements of the grounded theory by Corbin and Strauss.

RESULTS

Interviews were conducted with 46 AYAs with a UPCP. They were on average 33.4 years old (age range 23-44), and most of them were woman (63%). Additionally, five AYAs with a UPCP participated as AYA research partners in two focus groups. They were on average 31.8 years old and four of them were woman. AYAs with a UPCP reported four pillars for a satisfied healthcare experience: (1) trust, (2) tailored communication, (3) holistic empathic open attitude, and (4) care being offered (pro-)actively. They reported both optimal and suboptimal experiences about distrust based on a delay in diagnostic trajectory, lack of tailored communication and discussion of sensitive topics, preference for a holistic approach, and struggles with finding the way to get additional healthcare support.

CONCLUSION

For AYAs with a UPCP, it is important that both age-specific issues and issues related to the UPCP are understood and addressed; however, this seems not yet optimally implemented in clinical practice. This emphasizes the importance of providing this patient group with tailored care incorporating both aspects. Healthcare professionals need to be supported with training and tools to understand the healthcare needs of AYAs with a UPCP. AYAs can be empowered to take more control over their own healthcare needs.

Chemotherapy-Related Amenorrhea and Quality of Life Among Premenopausal Women With Breast Cancer

Importance

Younger survivors of breast cancer frequently report more treatment-related symptoms, mostly related to the menopausal transition.

Objective

To assess factors associated with chemotherapy-related amenorrhea (CRA) and to evaluate its association with long-term quality of life (QOL).

Design, Setting, and Participants

The prospective, longitudinal Cancer Toxicities Study, a multicenter French cohort study, includes women with a diagnosis of stage I to III breast cancer and collects data approximately yearly after diagnosis. The current study reports outcomes up to 4 years after diagnosis for participants enrolled from 2012 to 2017. Participants included premenopausal women younger than 50 years treated with chemotherapy and not receiving adjuvant ovarian function suppression. Data analysis was performed from September 2021 to June 2023.

Exposures

Clinical, socioeconomic, tumor, and treatment characteristics assessed at diagnosis (for the analysis of factors associated with CRA) and persistent CRA (for the QOL analysis).

Main Outcomes and Measures

The main outcome of interest was CRA at year 1 (Y1), year 2 (Y2), and year 4 (Y4) after diagnosis. Generalized estimating equations assessed associations of exposure variables with CRA. In the QOL analysis, QOL at Y4 (assessed with the European Organization for Research and Treatment of Cancer Quality of Life Questionnaires C30 and BR23) was the outcome of interest. Multivariable random-effect mixed models assessed the association of persistent CRA (ie, never recovering menses after treatment) with QOL.

Results

Among 1636 women, the mean (SD) age at diagnosis was 42.2 (5.6) years. Overall, 1242 of 1497 women (83.0%) reported CRA at Y1, 959 of 1323 women (72.5%) reported it at Y2, and 599 of 906 women (66.1%) reported it at Y4. Older age vs 18 to 34 years (adjusted odds ratio [OR] for 35 to 39 years, 1.84 [95% CI, 1.32 to 2.56]; adjusted OR for 40 to 44 years, 5.90 [95% CI, 4.23 to 8.24]; and adjusted OR for ≥45 years, 21.29 [95% CI, 14.34 to 31.61]) and receipt of adjuvant tamoxifen (adjusted OR, 1.97 [95% CI, 1.53 to 2.53]) were associated with higher likelihood of CRA. In the QOL analysis, 416 of 729 women (57.1%) had persistent CRA. However, late menses recovery among women aged 18 to 34 years with no menses at Y2 were reported by 11 of 21 women (52.4%) between Y2 and Y4. Persistent CRA was associated with worse insomnia (mean difference vs recovery at any time, 9.9 points [95% CI, 3.2 to 16.5 points]; P = .004), systemic therapy-related adverse effects (mean difference, 3.0 points [95% CI, 0.2 to 5.8 points]; P = .04), and sexual functioning (mean difference, -9.2 points [95% CI, -14.3 to -4.1 points]; P < .001) at Y4.

Conclusions and Relevance

In this cohort study of premenopausal women with breast cancer, persistent CRA was common, although some women recovered menses late, and was associated with worse long-term QOL. This study can help inform risk communication, personalized counseling, and early supportive care referrals for such patients.

Well-being trajectories in breast cancer and their predictors: A machine-learning approach

OBJECTIVE

This study aimed to describe distinct trajectories of anxiety/depression symptoms and overall health status/quality of life over a period of 18 months following a breast cancer diagnosis, and identify the medical, socio-demographic, lifestyle, and psychological factors that predict these trajectories.

METHODS

474 females (mean age = 55.79 years) were enrolled in the first weeks after surgery or biopsy. Data from seven assessment points over 18 months, at 3-month intervals, were used. The two outcomes were assessed at all points. Potential predictors were assessed at baseline and the first follow-up. Machine-Learning techniques were used to detect latent patterns of change and identify the most important predictors.

RESULTS

Five trajectories were identified for each outcome: stably high, high with fluctuations, recovery, deteriorating/delayed response, and stably poor well-being (chronic distress). Psychological factors (i.e., negative affect, coping, sense of control, social support), age, and a few medical variables (e.g., symptoms, immune-related inflammation) predicted patients' participation in the delayed response and the chronic distress trajectories versus all other trajectories.

CONCLUSIONS

There is a strong possibility that resilience does not always reflect a stable response pattern, as there might be some interim fluctuations. The use of machine-learning techniques provides a unique opportunity for the identification of illness trajectories and a shortlist of major bio/behavioral predictors. This will facilitate the development of early interventions to prevent a significant deterioration in patient well-being.

Patient-reported Quality of Life After Breast-conserving Surgery With Radiotherapy Versus Mastectomy and Reconstruction

OBJECTIVE

To compare long-term quality of life (QOL) outcomes in breast cancer survivors who received breast-conserving surgery with radiotherapy (BCS+RT) with those who received a mastectomy and reconstructive surgery (Mast+Recon) without radiotherapy and identify other important factors.

BACKGROUND

The long-term differences in patient-reported QOL outcomes following BCS+RT and Mast+Recon are not well understood.

METHODS

We identified patients from the Texas Cancer Registry with stage 0-II breast cancer diagnosed in 2009-2014 after BCS+RT or Mast+Recon without radiotherapy. Sampling was stratified by age and race and ethnicity. A paper survey was sent to 4800 patients which included validated BREAST-Q and PROMIS modules. Multivariable linear regression models were implemented for each outcome. Minimal clinically important difference for BREAST-Q and PROMIS modules, respectively, was 4 points and 2 points.

RESULTS

Of 1215 respondents (25.3% response rate), 631 received BCS+RT and 584 received Mast+Recon. The median interval from diagnosis to survey completion was 9 years. In adjusted analysis, Mast+Recon was associated with worse BREAST-Q psychosocial well-being (effect size: -3.80, P =0.04) and sexual well-being (effect size: -5.41, P =0.02), but better PROMIS physical function (effect size: 0.54, P =0.03) and similar BREAST-Q satisfaction with breasts, physical well-being, and PROMIS upper extremity function ( P >0.05) compared with BCS+RT. Only the difference in sexual well-being reached clinical significance. Older (≥65) patients receiving BCS+RT and younger (<50) patients receiving autologous Mast+Recon typically reported higher QOL scores. Receipt of chemotherapy was associated with detriments to multiple QOL domains.

CONCLUSIONS

Patients who underwent Mast+Recon reported worse long-term sexual well-being compared with BCS+RT. Older patients derived a greater benefit from BCS+RT, while younger patients derived a greater benefit from Mast+Recon. These data inform preference-sensitive decision-making for women with early-stage breast cancer.

Recommandations francophones pour la pratique clinique concernant la prise en charge des cancers du sein de Saint-Paul-de-Vence 2022-2023

With more than 60,000 new cases of breast cancer in mainland France in 2023 and 8% of all cancer deaths, breast cancer is the leading cancer in women in terms of incidence and mortality. While the number of new cases has almost doubled in 30 years, the percentage of patients at all stages alive at 5 years (87%) and 10 years (76%) testifies to the major progress made in terms of screening, characterisation and treatment. However, this progress, rapid as it is, needs to be evaluated and integrated into an overall strategy, taking into account the characteristics of the disease (stage and biology), as well as those of the patients being treated. These are the objectives of the St Paul-de-Vence recommendations for clinical practice. We report here the summary of the votes, discussions and conclusions of the Saint-Paul-de-Vence 2022-2023 RPCs.

Implementing a PROACTive Care Pathway to Empower and Support Survivors of Breast Cancer

PURPOSE

Optimal comprehensive survivorship care is insufficiently delivered. To increase patient empowerment and maximize the uptake of multidisciplinary supportive care strategies to serve all survivorship needs, we implemented a proactive survivorship care pathway for patients with early breast cancer at the end of primary treatment phase.

METHODS

Pathway components included (1) a personalized survivorship care plan (SCP), (2) face-to-face survivorship education seminars and personalized consultation for supportive care referrals (Transition Day), (3) a mobile app delivering personalized education and self-management advice, and (4) decision aids for physicians focused on supportive care needs. A mixed-methods process evaluation was performed according to the Reach, Effectiveness, Adoption, Implementation and Maintenance framework including administrative data review, pathway experience survey (patient, physician, and organization), and focus group. The primary objective was patient-perceived satisfaction with the pathway (predefined progression criteria for pathway continuation ≥70%).

RESULTS

Over 6 months, 321 patients were eligible for the pathway and received a SCP and 98 (30%) attended the Transition Day. Among 126 patients surveyed, 77 (66.1%) responded. 70.1% received the SCP, 51.9% attended the Transition Day, and 59.7% accessed the mobile app. 96.1% of patients were very or completely satisfied with the overall pathway, whereas perceived usefulness was 64.8% for the SCP, 90% for the Transition Day, and 65.2% for the mobile app. Pathway implementation seemed to be positively experienced by physicians and the organization.

CONCLUSION

Patients were satisfied with a proactive survivorship care pathway, and the majority reported that its components were useful in supporting their needs. This study can inform the implementation of survivorship care pathways in other centers.

Development and Content Validity of the Self-Care of Oral Anticancer Agents Index (SCOAAI)

OBJECTIVE

To develop and test the content validity of the Self-Care of Oral Anticancer Agents Index (SCOAAI).

DATA SOURCES

SCOAAI items were developed according to the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) criteria. The Middle Range Theory of Self-Care of Chronic Illnesses informed item generation. A four-phase procedure was followed; Phase 1: items were created based on a previous systematic review and a qualitative study; Phase 2: the SCOAAI comprehensibility and comprehensiveness were established through qualitative interviews with clinical experts and with patients (Phase 3); and Phase 4: the SCOAAI was then administered through an online survey to a group of clinical experts for the Content Validity Index (CVI) calculation.

CONCLUSION

The first version of the SCOAAI included 27 items. Five clinical experts and 10 patients tested the comprehensiveness and comprehensibility of instructions, items, and response options. Fifty-three experts (71.7% female, mean experience with patients on oral anticancer agents 5.8 years [standard deviation ± .2]; 66% nurses) participated in the online survey for content validity testing. The final version of the SCOAAI includes 32 items. Item CVI ranges between 0.79 and 1; the average Scale CVI is 0.95. Future studies will test the psychometric properties of the tool.

IMPLICATIONS FOR NURSING PRACTICE

The SCOAAI showed excellent content validity, confirming its usefulness for assessing self-care behaviors for patients on oral anticancer agents. By implementing this instrument, nurses could define and implement targeted interventions for improving self-care and obtaining more positive outcomes (eg, better quality of life, reduced hospitalizations and emergency department visits).

The Future of Breast Cancer Research in the Survivorship Field

Prevalence of survivors of breast cancer has been steadily increasing in the last 20 years. Currently, more than 90% of women diagnosed with early-stage breast cancer are expected to be alive at 5 years from diagnosis thanks to early detection and breakthrough innovations in multimodal treatment strategies. Alongside this advancement in clinical outcomes, survivors of breast cancer might experience several specific challenges and present with unique needs. Survivorship trajectories after diagnosis and treatment of breast cancer can be significantly impacted by long-lasting and severe treatment-related side effects, including physical problems, psychological distress, fertility issues in young women, and impaired social and work reintegration, which add up to patients' individual risk of cancer recurrence and second primary malignancies. Alongside cancer-specific sequelae, survivors still present with general health needs, including management of chronic preexisting or ensuing conditions. Survivorship care should implement high-quality, evidence-based strategies to promptly screen, identify, and address survivors' needs in a comprehensive way and minimize the impact of severe treatment sequelae, preexisting comorbidities, unhealthy lifestyles, and risk of recurrence on quality of life. This narrative review focuses on core areas of survivorship care and discuss the state of the art and future research perspectives in key domains including selected long-term side effects, surveillance for recurrences and second cancers, well-being promotion, and specific survivors' needs.

Baseline quality of life and chemotherapy toxicities in patients with early breast cancer

BACKGROUND

The authors used the French breast cancer Cancer and Toxicities (CANTO) cohort to study the associations between baseline quality of life and chemotherapy dose-reductions (CDRs) or postchemotherapy-toxicities (PCTs).

METHODS

In total, 3079 patients with breast cancer who received chemotherapy were included in this analysis. The associations between baseline physical functioning (PF) and fatigue measured using the European Organization for Research and Treatment of Cancer Quality-of-Life Questionnaire Core 30, and two endpoints-CDRs during adjuvant or neoadjuvant chemotherapy; and selected PCTs were estimated with odds ratios (ORs) and the corresponding 95% confidence intervals (CIs) using logistic regression models.

RESULTS

Among the 3079 patients from the CANTO cohort who were included, 718 (33.0%) received chemotherapy in the neoadjuvant setting, and 2361 (67.0%) received chemotherapy as adjuvant treatment. The chemotherapy included taxanes in 94.2% of patients and anthracyclines in 90.5% of patients. Overall, 15.5% of patients experienced CDRs and, 31.0% developed PCTs. Women with low baseline PF scores (<83) had higher multivariate odds of developing CDRs compared with those who had PF scores ≥83 (OR, 1.54; 95% CI, 1.13-2.09). The corresponding OR for PCTs was 1.50 (95% CI, 1.13-2.00). Women with high baseline fatigue scores had higher odds of CDRs (OR, 1.43; 95% CI, 1.13-1.76) and PCTs (OR, 1.32; 95% CI, 1.10-1.59).

CONCLUSIONS

By using the national CANTO cohort, baseline PF and fatigue were independently associated with CDRs and PCTs.

Community pharmacists’ measurement of health-related quality of life for breast cancer with positive hormone receptors: A prospective observational study

Objectives:

Many patients with hormone-receptor positive breast cancer undergo prolonged treatment. However, the long-term patient quality of life assessment has not been examined. Using community pharmacists’ assistance is one method for assessing long-term quality of life. Thus, this study aimed to understand the ongoing health-related quality of life and quality-adjusted life year among breast cancer patients so that community pharmacists may contribute to their pharmacotherapy.

Methods:

We conducted a prospective observational study with 22 breast cancer patients who had health-related quality of life at the initial measurement and 6 months later.

Results:

Regarding the health-related quality of life, quality-adjusted life year concerning all patients was 0.890 (95% confidence interval: 0.846–0.935). Quality-adjusted life year concerning those younger than 65 years was 0.907 (95% confidence interval: 0.841–0.973), and that for individuals older than 65 years was 0.874 (95% confidence interval: 0.804–0.943). The adjuvant chemotherapy group had a lower health-related quality of life at the initial measurement (0.887; 95% confidence interval: 0.833–0.941) but showed a higher quality of life 6 months later (0.951; 95% confidence interval: 0894–1.010). Quality-adjusted life year for individuals regarding adjuvant chemotherapy was 0.919 (95% confidence interval: 0.874–0.964). In contrast, the life-prolonged group had a higher health-related quality of life at the initial measurement, which was lower 6 months later.

Conclusions:

As a result of measuring quality of life using the EuroQol 5-dimensions-5-levels, this study revealed a decline in health-related quality of life in patients undergoing hormonal therapy for breast cancer. The study is expected to assist community pharmacists in managing outpatients.
