Coping with chemotherapy for breast cancer: Asking women what works

The effect of an interactive nurse support program developed with a mobile application on patient outcomes in breast cancer patients who received outpatient chemotherapy: A randomized controlled trial

PURPOSE

To determine the effect of the interactive nurse support program developed with a mobile application on patient outcomes (symptom management, quality of life, perception of social support, anxiety) in breast cancer patients who received outpatient chemotherapy.

METHODS

The randomized controlled study was conducted in the outpatient chemotherapy unit of a public hospital between 2021 and 2023. The study sample consisted of 100 breast cancer patients receiving anthracycline-cyclophoshamide chemotherapy. Patients in the control group received standard care, and patients in the intervention group were applied an interactive nurse support program developed with a mobile application throughout four chemotherapy cycles. Memorial Symptom Assessment Scale (MSAS), EORTC QLQ-C30, EORTC QLQ-BR23 Scales, Multidimensional Perceived Social Support Scale (MPSSS), Beck Anxiety Scale (BAS) were used in data collection. Data were collected five times, including before chemotherapy (t0) and at the end of the first week after each chemotherapy (t1, t2, t3, t4).

RESULTS

MSAS, BAS total scores, EORTC QLQ-C30 and EORTC QLQ-BR23 Scales "Symptom Dimension" scores of the patients in the intervention group were found to be significantly lower than the control group at t1, t2, t3, t4 (p˂0.05). EORTC QLQ-C30 Scale "General Well-Being", "Functional Status", EORTC QLQ-BR23 "Functional Status" scores, MPSSS total scores of the patients in the intervention group were found to be significantly higher than the control group at t1, t2, t3, t4 measurements (p˂0.05).

CONCLUSIONS

The interactive nurse support program developed with the mobile application is effective on patient outcomes in breast cancer patients who received outpatient chemotherapy.

Effect of training based on Orem's self-care deficit theory on breast cancer patients' management of chemotherapy-related side effects and self-care behaviors: A randomized controlled trial

PURPOSE

To examine the effects of training based on Orem's self-care deficit theory on breast cancer patient's physical, social, and psychological well-being and self-care behaviors during chemotherapy.

METHODS

This randomized controlled trial was based on a pretest-posttest experimental design. The study sample consisted of 62 breast cancer patients (n = 31 for each of the intervention and control groups) receiving cyclophosphamide-epirubicin or cyclophosphamide-adriamycin treatment in the medical oncology department of a university hospital in Tekirdağ, Turkey. The breast cancer patients in the intervention group received training based on Orem's self-care deficit theory regarding physical, social, and psychological well-being and self-care behaviors during chemotherapy. The researcher conducted two face-to-face follow-ups (during the second and third chemotherapy cycles, 3 weeks apart) and a posttest assessment. Pretest and posttest symptom scores and self-care survey results were compared for both groups.

RESULTS

The Nightingale Symptom Assessment Scale (N-SAS) first follow-up, second follow-up, and posttest scores showed that the intervention group experienced fewer negative changes in quality of life than the control group based on the physical, social, and psychological subdimension and total scale scores (p < .05). The most positive changes in the intervention group's self-care behaviors were observed for items about caring for and protecting hair, using protective gloves when doing chores, monitoring weight, and limiting social meetings when blood values were low to protect against possible infection.

CONCLUSION

Training based on Orem's self-care deficit theory positively influenced breast cancer patients' management of chemotherapy-related side effects and self-care behaviors. Chemotherapy-related side effects should be evaluated frequently. Moreover, patients' needs should be determined, and training should be tailored to their needs.

Coping With Side Effects: A Daily Diary Study in Women With Breast Cancer Living With Adjuvant Endocrine Therapy

OBJECTIVE

Adjuvant endocrine therapy (AET) is increasingly being prescribed for up to 10 years to people diagnosed with hormone receptor-positive breast cancer. AET intake is often accompanied by side effects that significantly impact the well-being of people. The way individuals cope with medication-related side effects might play a pivotal role in their emotional adaption.

METHODS

This intensive-longitudinal study investigated the association between self-reported coping strategies (Brief COPE) and psychological well-being (Patient Health Questionnaire-4) among women undergoing AET. A multilevel factor analysis resulted in the identification of four coping factors, namely, problem-focused, support-focused, meaning-focused, and avoidance-focused coping. Daily coping efforts and experienced side effects were analyzed as predictors of psychological well-being using multilevel modeling.

RESULTS

A total of 215 women (Mage = 56.5 ± 10.9 years) participated, resulting in a total of n = 2080 daily surveys (M = 9.67 ± 1.08). On average, women reported 3.7 ± 2.2 different side effects per day. Days characterized by an elevated frequency of side effects and increased burden were associated with diminished well-being. Using more problem- and meaning-focused strategies than usual to cope with side effects correlated positively with well-being. Conversely, employing more support- and avoidance-focused coping strategies than usual was linked to reduced psychological well-being. Exploratory analyses focusing on individual coping strategies provided nuanced insights into coping behaviors.

CONCLUSION

The present findings underscore the relationship between women's coping efforts concerning medication-related side effects during AET and their daily well-being. Psychosocial education (e.g., cognitive behavioral therapy) may offer valuable benefits for patients by helping them develop adaptive coping strategies to manage side effects.

Patients' and Clinicians' Perceptions of the Clinical Utility of Predictive Risk Models for Chemotherapy-Related Symptom Management: Qualitative Exploration Using Focus Groups and Interviews

BACKGROUND

Interest in the application of predictive risk models (PRMs) in health care to identify people most likely to experience disease and treatment-related complications is increasing. In cancer care, these techniques are focused primarily on the prediction of survival or life-threatening toxicities (eg, febrile neutropenia). Fewer studies focus on the use of PRMs for symptoms or supportive care needs. The application of PRMs to chemotherapy-related symptoms (CRS) would enable earlier identification and initiation of prompt, personalized, and tailored interventions. While some PRMs exist for CRS, few were translated into clinical practice, and human factors associated with their use were not reported.

OBJECTIVE

We aim to explore patients' and clinicians' perspectives of the utility and real-world application of PRMs to improve the management of CRS.

METHODS

Focus groups (N=10) and interviews (N=5) were conducted with patients (N=28) and clinicians (N=26) across 5 European countries. Interactions were audio-recorded, transcribed verbatim, and analyzed thematically.

RESULTS

Both clinicians and patients recognized the value of having individualized risk predictions for CRS and appreciated how this type of information would facilitate the provision of tailored preventative treatments or supportive care interactions. However, cautious and skeptical attitudes toward the use of PRMs in clinical care were noted by both groups, particularly in relationship to the uncertainty regarding how the information would be generated. Visualization and presentation of PRM information in a usable and useful format for both patients and clinicians was identified as a challenge to their successful implementation in clinical care.

CONCLUSIONS

Findings from this study provide information on clinicians' and patients' perspectives on the clinical use of PRMs for the management of CRS. These international perspectives are important because they provide insight into the risks and benefits of using PRMs to evaluate CRS. In addition, they highlight the need to find ways to more effectively present and use this information in clinical practice. Further research that explores the best ways to incorporate this type of information while maintaining the human side of care is warranted.

Stress symptoms occur in patients undergoing chemotherapy treatment independently of the level of physical activity

The cancer patient is undergoing a set of procedures that affect the physical and psychological balance, which can generate stressful situations in the organism. In turn, physical activity helps to treat stress, promoting well-being and reducing anxiety. Our study aimed to verify the influence of physical activity practice on stress symptoms in patients undergoing oncological chemotherapy treatment. For this, we used Lipp's Inventory of Stress Symptoms (ISSL) and the International Physical Activity Questionnaire (IPAQ) in 56 patients with cancer. Our data show that 45.4% of the participants exhibited stress scores, of which, 21.8% were at near to exhaustion, and 23.6% at exhaustion. We observed that 30% of them are considered sufficiently active, 25% insufficiently active, 45% sedentary. No association was observed between physical activity and stress. These findings indicate that stress symptoms occur in patients undergoing chemotherapy treatment regardless of the level of physical activity.

Psychological Aspects of Breast Cancer

Breast cancer is the most commonly diagnosed cancer in women. Associated psychological symptoms include stress, adjustment difficulties, anxiety, depression, impaired cognitive function, sleep disturbances, altered body image, sexual dysfunction, and diminished overall well-being. Distress screening and assessment identifies women who will benefit from therapeutic interventions. Addressing these symptoms improves compliance with treatment and outcomes including disease-related outcomes, psychological symptoms, and quality of life. The most effective treatments include teaching coping skills such as expressing emotion, along with other structured cognitive behavioral, interpersonal, and mindfulness approaches. Patients should be provided these psychosocial supports throughout their cancer journey.

Patient Understanding of Chemotherapy and Goals of Care as Provided by Different Care Team Members

Chemotherapy can be challenging and overwhelming for patients, but when patients are knowledgeable about chemotherapy, their comfort level, overall satisfaction, and coping improve. It is currently unknown whether patients prefer information about chemotherapy to be provided by specific care team members and whether demographic characteristics affect learning preferences. We developed a 31-question questionnaire that asked patients when chemotherapy information was discussed and who they wanted that information to come from. The questionnaire was given to 50 patients who had completed 1 cycle of chemotherapy. Patients were evenly distributed among age categories of 45 to 64 years, 65 to 74 years, and 75 years or older. Thirty participants (60%) were women, 33 (66%) had high school degrees, and 23 (46%) were receiving their first chemotherapy regimen. Sixty percent of patients best understood goals of care from oncologists, 70% wanted goals of care to come from oncologists, and 61% best understood and wanted to understand logistics of chemotherapy from oncologists. Sixty-six percent of patients understood adverse effects when they were explained by nursing staff, and 56% wanted explanations of adverse effects to come from nursing staff. Patients did not prefer a specific care team member or information source when receiving financial cost information. Patients often preferred to receive chemotherapy information from their oncologist; however, other members of the care team also provided information to patients in a way that was understood.

How do I deal with breast cancer: a qualitative inquiry into the coping strategies of Iranian women survivors

Background

Breast cancer is the most frequent cancer in Iran. Understanding the coping strategies employed by cancer survivors can provide valuable information for designing interventions to help them adapt to the problems produced by cancer and its treatment. This study aimed to explore the coping strategies of BC survivors in Iran.

Methods

This qualitative study was conducted in Mashhad, Northeast Iran, between April and December 2021. Fourteen BC survivors were selected through purposive sampling. The data were collected using semi-structured interviews. Data were analyzed using conventional content analysis adopted by Graneheim and Lundman. MAXQDA 12 software was used for data organization. Components of trustworthiness, including credibility, dependability, confirmability, and transferability, were considered.

Results

The main categories that emerged from the participants' data analysis were “behavioral coping strategies” and “emotional coping strategies.” Behavioral coping strategies included efforts to adopt healthy nutrition, attempts to improve a healthy lifestyle, maintenance of everyday activities, use of specialized cancer support consultation services, and seeking to increase health literacy about BC. The emotional coping strategies consisted of denial as a temporary escape route, positive thinking and focusing on the positive aspects of life, reinforcement of spirituality, and seeking the support of relatives.

Conclusion

Our findings provide an in-depth understanding of Iranian women’s strategies for coping with BC. A trained team of oncologists, psychiatrists, mental health professionals, and reproductive health specialists needs to contribute significantly to improving the coping ability of patients with cancer, which could lead to enhanced health promotion and a higher quality of life.

Psychological Distress, Coping Strategies, and Quality of Life in Breast Cancer Patients Under Neoadjuvant Therapy: Protocol of a Systematic Review

Introduction

Women with breast cancer eligible for neoadjuvant therapy (NAT) present a disorder of biopsychosocial variables and alteration of their quality of life. They cope with this changing by adopting psychological adjustment strategies, either passive or active. This systematic review aims to investigate the psychological distress, coping strategies, and quality of life in breast cancer patients under neoadjuvant therapy.

Methods

Cochrane Library, PubMed, ScienceDirect, Scopus, Web of Science, and Wiley Online library represent the databases that were searched to identify relevant published articles until September 27, 2021. Full-text published articles, written in English and assessing the main outcomes (namely: psychological distress, coping strategies, and quality of life) in women with breast cancer under NAT will be included. Also, we will integrate papers dealing with the related bio psychosocial variables to the main variables. The paper selection, data extraction, and quality assessment of selected studies will be performed independently by two researchers, and disagreements will be resolved through discussions. We will bring together the results of all of the included studies to draw conclusions based on the body of evidence. The narrative approach will be adopted to analyze the results and conclusions extracted and we would perform quantitative groupings if we have similar data.

Ethics and dissemination

Ethical approval is not required as the proposed systematic review will not use primary data. The results of this review will be disseminated through publication in a peer-reviewed journal and conference presentation(s). PROSPERO registration number: CRD42021230300.

Existential Meaning-Making Coping in Iran: A Qualitative Study among Patients with Cancer

This article is written on the basis of a study on meaning-making coping in Iran. The study is a part of an international project in 10 countries with different religious and cultural backgrounds. This article aims to discuss the secular existential meaning-making coping methods employed by Iranian cancer patients. Interviews were conducted with 27 participants with various kinds of cancer. Nine secular existential meaning-making coping strategies emerged from the analyses of the qualitative interviews. These coping methods are as follows: Ignoring the illness, Distraction, Altruism, Encounter with others, Nature, Discourse of the self, Visualization, Positive solitude, and Positive thinking and transformational orientation. It seems that, using these strategies, our sample of Iranian cancer patients/survivors have been denying/ignoring their illness, and/or empowering themselves. We discuss the results, considering the potential influence of cultural elements, including Iranian Islam, Persian mysticism, and Persian literature, on the selection of the coping strategies. The study contributes to our understanding of coping via elucidating how seriously ill individuals in Iran try to manage the challenges caused by a health crisis.

Pre-surgery supportive and goal-oriented strategies are associated with lower post-surgery perceived distress in women diagnosed with breast cancer

BACKGROUND

Psycho-oncology literature pointed out that individual health outcomes may depend on patients' propensity to adopt approach or, conversely, avoidant coping strategies. Nevertheless, coping factors associated with postoperative distress remain unclear, unfolding the lack of tailored procedures to help breast cancer patients manage the psychological burden of scheduled surgery. In view of this, the present study aimed at investigating: 1. pre-/post-surgery distress variations occurring among women diagnosed with breast cancer; 2. the predictivity of approach and avoidant coping strategies and factors in affecting post-surgery perceived distress.

METHODS

N = 150 patients (mean age = 59.37; SD =  ± 13.23) scheduled for breast cancer surgery were administered a screening protocol consisting of the Distress Thermometer (DT) and the Brief-COPE. The DT was used to monitor patients' distress levels before and after surgery (± 7 days), whereas the Brief-COPE was adopted only preoperatively to evaluate patients' coping responses to the forthcoming surgical intervention. Non-parametric tests allowed for the detection of pre-/post-surgery variations in patients' perceived distress. Factor analysis involved the extraction and rotation of principal components derived from the Brief-COPE strategies. The predictivity of such coping factors was investigated through multiple regression (Backward Elimination).

RESULTS

The Wilcoxon Signed-Rank Test yielded a significant variation in DT mean scores (TW = -5,68 < -zα/2 = -1,96; p < .001) indicative of lower perceived distress following surgery. The four coping factors extracted and Varimax-rotated were, respectively: 1. cognitive processing (i.e., planning + acceptance + active coping + positive reframing); 2. support provision (i.e., instrumental + emotional support); 3. emotion-oriented detachment (i.e., self-blame + behavioral disengagement + humor + denial); 4. goal-oriented detachment (i.e., self-distraction). Among these factors, support provision (B = .458; β = - .174; t = - 2.03; p = .045), encompassing two approach coping strategies, and goal-oriented detachment (B = .446; β = - .176; t = - 2.06; p = .042), consisting of one avoidant strategy, were strongly related to post-surgery distress reduction.

CONCLUSION

The present investigation revealed that the pre-surgery adoption of supportive and goal-oriented strategies led to postoperative distress reduction among breast cancer patients. These findings highlight the importance of timely psychosocial screening and proactive interventions in order to improve patients' recovery and prognosis.

Information seeking for coping with cancer: a systematic review

Purpose

Information seeking can be used to make sense of a situation or solve a problem. Information seeking can be considered a coping strategy when facing illness, crisis or other life-changing events. Cancer is a globally occurring, life-threatening disease, and this review aims to provide an overview of the existing literature on the active information seeking behaviour of cancer patients specifically focussing on how active information seeking serves as a coping strategy.

Design/methodology/approach

This study adheres to current guidelines for conducting systematic reviews and consequently, thorough literature searches were conducted in four databases: Medline, Embase, CINAHL and Scopus which resulted in 7,179 publications. Following a careful screening process, this systematic review identifies 14 studies on the use of information seeking to cope with cancer.

Findings

The included studies consist of both qualitative and quantitative approaches to analysing the use of information seeking to cope with cancer. The included studies have focussed primarily on demographic factors, the impact of affect, information needs, sources and coping strategies.

Research limitations/implications

A number of research gaps within library and information science are identified. Bringing research in this field into information science could allow for a greater understanding of information literacy, the use of existing information and the process of information searching when using information seeking to cope with serious illness.

Originality/value

This systematic review focusses on how information seeking serves as a coping strategy for cancer patients and provides an overview of the recent literature.

Optimization assisted Kalman filter for cancer chemotherapy dosage estimation

Cancer is regarded to be the earth's most deadly disease, with one of the highest mortality rates among people. "Surgery, radiotherapy, chemotherapy, hormone therapy, and immunotherapy" were all options for treat cancer. Chemotherapy is a medication that is most often deployed for treating cancer, as cancer cells develop and proliferate faster than other cells in the body. Even though chemotherapy is an effective method to treatment various kinds of cancers, the treatment includes risk as it causes side effects due to improper drug usage. The application of a controller-based strategy for determining the optimal rate of drug injection during treatment has risen dramatically in recent years. Thereby, this work develops a robust controller for controlling the dosage of drugs that is carried out under parameter estimation. In addition, a Modified Regularized Error Function-based Extended Kalman filter (MREF-EKF) is introduced for estimating the tumor cells and it can be exploited for diverse conditions. Moreover, the overfitting issue that occurs during drug dosage estimation is also solved using this approach. Further, to improve the performance of the developed approach, the initial state of EKF is fine-tuned via Mean fitness-based Particle Swarm Update (MF-PSU), which is the enhanced version of Particle Swarm Optimization (PSO). At last, the supremacy of the presented approach is proved with respect to convergence analysis and error analysis. For instance, our method outperforms existing GWO + ek + m, AGWO + ek + m, and PSO + ek + m approaches in convergence analysis at noise level 0.41 by 0.009%, 0.002%, and 4.9% respectively. In error analysis, the error values for tumor cells have reached a minimum error value of zero for all noise levels (0.41, 0.43, and 0.55). The findings of this study can help for a better understanding of our presented robust controller's effectiveness in controlling the dosage of drugs.

Psychological distress among Chinese patients with breast cancer undergoing chemotherapy: Concordance between patient and family caregiver reports

AIMS

To examine patient-caregiver concordances about psychological distress among Chinese patients with breast cancer undergoing chemotherapy and identify factors related to concordance among patients and family caregivers.

DESIGN

Cross-sectional study.

METHODS

From October 2019 to June 2020, 137 patient-caregiver dyads were enrolled. Sociodemographic information, the distress thermometer (including the problem list), the Distress Disclosure Index and the Family Adaptability and Cohesion Evaluation Scale were used to collect data. Data were analysed using intraclass correlation coefficients (ICC), kappa statistics, two related samples test, chi-square tests and/or Fisher's exact tests and binary logistic regression.

RESULTS

Overall, fair agreement was identified between patients' and caregivers' reports (intraclass correlation coefficients [ICC] = .528). Patients reported significantly higher psychological distress scores than paired caregiver reports. Lower psychological distress concordance was found among patients with comorbidities (odds ratio [OR], 0.352; 95% confidence interval [CI], 0.155-0.798) and lower levels of self-disclosure (OR, 0.402; 95% CI, 0.186-0.868).

CONCLUSION

There was relatively low concordance between patients' reports and caregivers' perceptions of psychological distress. Family caregivers tended to underestimate patients' psychological distress. A comorbid condition and lower levels of self-disclosure contributed to this bias.

IMPACT

Having an awareness of the incongruence between patient and caregiver may help healthcare providers better interpret caregiver assessments. Healthcare providers should reinforce patient-caregiver dyadic psychosocial education to improve concordance. More psychological care and substantial emotional support should be provided for Chinese breast cancer patients undergoing chemotherapy by family caregivers and healthcare providers.

Expanding Application of the Long-Term Quality of Life Instrument to the Population of Women Undergoing Treatment of Advanced Breast Cancer

BACKGROUND

The Long-Term Quality of Life (LTQL) instrument was designed for female cancer survivors who have completed treatment and includes an existential spirituality subscale that is omitted in many other quality of life scales. Women with advanced breast cancer are now living longer, while also expressing greater spiritual concerns.

OBJECTIVE

The objective of this analysis was to test the psychometric properties of the LTQL among women undergoing treatment of advanced breast cancer.

METHODS

This secondary analysis was based on a sample of 385 women. Validity was evaluated using a confirmatory factor analysis and associations with Functional Assessment of Cancer Therapy-Breast Cancer. Internal consistency reliability was assessed using Cronbach's α for each subscale of the LTQL.

RESULTS

The mean age was 56 years, 84% of participants were white, and 69% had metastasis. Model fit indices for the confirmatory factor analysis were acceptable, with the root mean square error of approximation of 0.076 (90% confidence interval, 0.071-0.081) and a comparative fit index of 0.91. The LTQL subscale scores were significantly correlated with the subscales of the Functional Assessment of Cancer Therapy-Breast Cancer of similar conceptual content. Internal consistency reliability for the subscales ranged from 0.80 to 0.86.

CONCLUSIONS

The factor structure of the LTQL was consistent with previous findings in long-term female cancer survivors. The instrument has adequate psychometric properties for use among women with advanced breast cancer.

IMPLICATIONS FOR PRACTICE

The LTQL can be used to assess the physical, psychosocial, and existential spiritual domains of quality of life among women with advanced breast cancer as well as in long-term female cancer survivors.

Chemotherapy-Induced Nausea and Vomiting in Breast Cancer Patients: A Multicenter Prospective Observational Study

Objective:

This study aimed to assess the occurrence of chemotherapy-induced nausea and vomiting (CINV) in acute phase (24 h after chemotherapy) and delayed phase (2–5 days after chemotherapy) after standard antiemetic therapy and to explore the risk factors of CINV in the acute and delayed phases.

Methods:

This prospective and observational study analyzed the data of 400 breast cancer patients scheduled for chemotherapy in two hospitals. The self-report survey was developed to assess the occurrence of CINV and their associated factors. On day 2 and day 6 of chemotherapy, CINV was evaluated by the Multinational Association of Supportive Care in Cancer Antiemetic Tool (MAT). The incidence of acute and delayed CINV was expressed as frequency and percentage.

Results:

Among 400 patients, 29.8% and 23.5% experienced acute and delayed CINV, respectively. Logistic regression analysis showed that the risk factors associated with acute CINV included pain/insomnia, history of CINV, and highly emetogenic chemotherapy. The history of motion sickness (MS), history of CINV, number of chemotherapy cycles completed, and the incidence of acute CINV were significant risk factors for delayed CINV (all P < 0.05).

Conclusions:

The results of this study are helpful for nurses to identify high-risk patients with CINV, formulate effective treatment plans, and reduce the incidence of CINV.

Active Participation, Mind-Body Stabilization, and Coping Strategies with Integrative Medicine in Breast Cancer Patients

PURPOSE

Increasing numbers of breast cancer survivors have led to a growing demand for integrative medicine. When patients have completed treatments associated with severe side effects, attention turns to reducing psychological symptoms, coping behavior, and self-care. The aim of this study was to assess patient-reported benefits in relation to active participation, mind-body stabilization, and coping strategies in breast cancer patients receiving integrative medicine.

METHODS

In a cross-sectional study, health counseling and treatment provided by a standardized integrative medicine consultancy service at the University Breast Center of Franconia were evaluated in 75 breast cancer patients over a 15-month period. At the baseline, the patients answered a questionnaire on their medical history, symptoms, and the treatment goals they were hoping to achieve with integrative medicine. Patient-reported outcomes relative to active participation, mind-body stabilization, and coping strategies were analyzed.

RESULTS

A large majority of the patients had previous experience with integrative medicine (91%). Most reported that they achieved their treatment goals with integrative medicine. Ninety-one percent achieved active participation in cancer treatment, 90% mind-body stabilization, and 79% improvement in coping strategies. Besides active participation, which was greatest in patients with stable disease, the success of integrative therapy was independent of age, concomitant diseases, previous integrative medicine experience, treatment state, and systemic cancer therapy.

CONCLUSION

Breast cancer patients benefit from the counseling and treatment provided with integrative medicine in mind-body stabilization and coping with cancer. Active participation in cancer treatment is important for the patients. Integrative treatment services should form part of routine patient care.

Perceived social support, coping strategies, anxiety and depression among women with breast cancer: Evaluation of a mediation model

PURPOSE

Depression and anxiety are now considered as common adverse reactions to cancer. Prior research has shown that social support and functional coping strategies alleviate depressive and anxious symptoms of cancer patients but the exact relationship between social support and coping strategies in amelioration of the symptoms is yet to be elaborated.

METHODS

The current study examined the relationship between social support, coping strategies and depressive-anxious symptomatology and explored the possible role of coping strategies in mediating the relationship between social support, depression and anxiety in Iranian breast cancer patients (N = 221). Anxiety and depressive symptoms were measured using the Depression-Anxiety-Stress (DASS-21) scale, social support was measured using the Medical Outcome Survey, Social Support Scale (MOSS-SSS), and coping strategies were measured using the brief COPE.

RESULTS

All of the social support subscales were negatively correlated with depression and anxiety. Most of the coping strategies were negatively correlated with depressive-anxious symptoms. When controlling for covariates, mediation analysis revealed that active coping, positive reframing and acceptance partially mediated the association of social support of different types with depression. Positive reframing also partially mediated the relationship of the total social support and positive social interactions with anxiety.

CONCLUSIONS

High levels of social support may relieve depressive and anxious symptoms of breast cancer patients through functional coping. The management of breast cancer patients should also focus on providing patients with social support and educating them on the practice of functional coping strategies.

Regularized error function-based extended Kalman filter for estimating the cancer chemotherapy dosage: impact of improved grey wolf optimization

Objectives

The main aim of this work is to introduce a robust controller for controlling the drug dosage.

Methods

The presented work establishes a novel robust controller that controls the drug dosage and it also carried out parameters estimation. Along with this, a Regularized Error Function-based EKF (REF-EKF) is introduced for estimating the tumor cells that could be adapted for different conditions. It also assists in solving the overfitting problems, which occur during the drug dosage estimation. Moreover, the performance of the adopted controller is compared over other conventional schemes, and the attained outcomes reveal the appropriate impact of drug dosage injection on immune, normal, and tumor cells. It is also ensured that the presented controller does a robust performance on the parameter uncertainties. Moreover, to enhance the performance of the proposed system and for fast convergence, it is aimed to fine-tune the initial state of EKF optimally using a new Improved Gray Wolf Optimization (GWO) termed as Adaptive GWO (AGWO). Finally, analysis is held to validate the betterment of the presented model.

Results

The outcomes, the proposed method has accomplished a minimal value of error with an increase in time, when evaluated over the compared models.

Conclusions

Thus, the improvement of the proposed REF-EKF-AGWO model is proved from the attained results.

Robust controller for cancer chemotherapy dosage using nonlinear kernel-based error function

It is well-known that chemotherapy is the most significant method on curing the most death-causing disease like cancer. These days, the use of controller-based approach for finding the optimal rate of drug injection throughout the treatment has increased a lot. Under these circumstances, this paper establishes a novel robust controller that influences the drug dosage along with parameter estimation. A new nonlinear error function-based extended Kalman filter (EKF) with improved scaling factor (NEF-EKF-ISF) is introduced in this research work. In fact, in the traditional schemes, the error is computed using the conventional difference function and it is deployed for the updating process of EKF. In our previous work, it has been converted to the nonlinear error function. Here, the updating process is based on the prior error function, though scaled to a nonlinear environment. In addition, a scaling factor is introduced here, which considers the historical error improvement, for the updating process. Finally, the performance of the proposed controller is evaluated over other traditional approaches, which implies the appropriate impact of drug dosage injection on normal, immune and tumor cells. Moreover, it is observed that the proposed NEF-EKF-ISF has the ability to evaluate the tumor cells with a better accuracy rate.

"I Wish Someone Had Told Me That Could Happen": A Thematic Analysis of Patients' Unexpected Experiences With End-Stage Kidney Disease Treatment

BACKGROUND

Preparedness regarding prognosis and treatment options enables patients to cope with uncertainties, make value-based treatment decisions, and set treatment goals. Yet, little is known about the expectedness of end-stage kidney disease (ESKD) patients' treatment experiences beyond their desire for better treatment education.

OBJECTIVE

To describe unexpected adverse treatment experiences among ESKD patients.

METHOD

The authors conducted 7 focus groups with 55 dialysis patients and living-donor kidney transplantation recipients receiving medical care in Baltimore, Maryland. Data were analyzed thematically. Themes present in different treatment groups were highlighted to provide insight into common experiences.

RESULTS

The authors identified 5 themes: (1) psychological reactions, (2) constrained freedom of choice, (3) treatment delivery and logistics, (4) morbidity, and (5) finances.

CONCLUSION

Patients were unprepared for nonclinical, logistical, and clinical aspects of ESKD treatment. The need for providers' use of tailored preparatory techniques and the development of pretreatment interventions to help patients know what to expect from and feel psychologically prepared for treatment, particularly with respect to nonclinical implications, is critical. These efforts have great potential to improve patients' treatment experiences.

Reduced symptom burden with the support of an interactive app during neoadjuvant chemotherapy for breast cancer - A randomized controlled trial

Objectives

Neoadjuvant chemotherapy causes distressing symptoms, which have to be managed by patients at home. Assessing and acting upon relevant patient-reported symptoms regularly with the support of mHealth such as apps, has shown to decrease symptom burden and improve health-related quality of life (HRQoL). There is a lack of apps for patients with breast cancer which are tested in rigorous trials and only a few include interactive components for immediate clinical management. The aim of this study was to evaluate whether the use of the interactive app Interaktor improves patients’ levels of symptom burden and HRQoL during neoadjuvant chemotherapy for breast cancer.

Materials and methods

This randomized controlled trial included patients in an intervention group (n = 74) and a control group (n = 75), recruited at two university hospitals in Stockholm, Sweden. The intervention group used Interaktor for symptom reporting, self-care advice and support from health-care professionals during treatment, and the control group received standard care alone. Self-reported symptoms and HRQoL were assessed at two time points to determine differences between the groups.

Results

The intervention group rated statistically significant less symptom prevalence in nausea, vomiting, feeling sad, appetite loss and constipation. Overall symptom distress and physical symptom distress were rated statistically significant lower in the intervention group. Further, emotional functioning was rated statistically significant higher in the intervention group.

Conclusions

By using the Interaktor app in clinical practice, patients get individual support when managing treatment-related symptoms during neoadjuvant chemotherapy for breast cancer, leading to decreased symptom burden and improved emotional functioning.

•

Using the app Interaktor reduced symptom burden in patients with breast cancer.

•

The use of Interaktor enhanced emotional functioning during treatment.

•

Interaktor provided individual support during neoadjuvant chemotherapy.

A single exercise session improves side-effects of chemotherapy in women with breast cancer: an observational study

Background

To measure changes in four common chemotherapy related side-effects (low energy, stress, nausea and pain) immediately after a single exercise session within the first week after treatment.

Methods

Thirty-eight patients with chemotherapy-treated breast cancer, participating in a multi-centre randomised controlled study, the Physical Training and Cancer study (Phys-Can) were included in this sub-study. The Phys-Can intervention included endurance and resistance training. Before and after a single training session (endurance or resistance) within the first week of chemotherapy, energy and stress were measured with the Stress-Energy Questionnaire during Leisure Time, and nausea and pain were assessed using a Visual Analog Scale 0–10. Paired t-tests were performed to analyse the changes, and linear regression was used to analyse associations with potential predictors.

Results

Thirty-eight participants performed 26 endurance training sessions and 31 resistance training sessions in the first week after chemotherapy. Energy and nausea improved significantly after endurance training, and energy, stress and nausea improved significantly after resistance training. Energy increased (p = 0.03 and 0.001) and nausea decreased (p = 0.006 and 0.034) immediately after a single session of endurance or resistance training, and stress decreased (p = 0.014) after resistance exercise.

Conclusions

Both endurance and resistance training were followed by an immediate improvement of common chemotherapy-related side-effects in patients with breast cancer. Patients should be encouraged to exercise even if they suffer from fatigue or nausea during chemotherapy.

The effect of informational-emotional support program on illness perceptions and emotional coping of cancer patients undergoing chemotherapy

PURPOSE

The present study aims to assess the effect of a nurse-led informational-emotional support program on illness perceptions and emotional coping of cancer patients undergoing chemotherapy.

METHODS

We used a quasi-experimental design, pre- and post-test. A total of 80 cancer patients undergoing chemotherapy were selected by convenience sampling method and assigned to experimental (n = 40) and control groups (n = 40). The nurse-led informational-emotional support program included five face-to-face sessions, educational booklet, and five phone follow-ups, and was conducted for the experimental group over 10 weeks. The control group received routine cares. The outcomes were assessed at baseline and end of intervention and included illness perceptions, which were assessed using the Illness Perception Questionnaire-Revised (IPQ-R), and emotional coping as the secondary outcome using the Coping Through Emotional Approach Scale. Data were analyzed in SPSS using multivariate analysis of covariance (MANCOVA) models, t test, paired t test, and chi-square.

RESULTS

Between group analysis showed that the mean scores of global illness perceptions and subscales including timeline, consequences, controllability, and coherence significantly increased in the experimental group compared to the control (P < 0.001), but no significant change was observed in two groups in the subscale of emotional representation (P < 0.571) and in the secondary outcome including emotional coping (P < 0.08).

CONCLUSIONS

A 10-week nurse-led informational-emotional support program can lead to changed illness perceptions without changing emotional coping. The effect of this support program should be studied on the coping and illness perceptions over the trajectory of cancer, especially in end stages in the future.
