Factors influencing adherence to cancer treatment in older adults with cancer: a systematic review

Development and evaluation of a sustainable video health education program for newly diagnosed breast cancer patients in Malaysia

PURPOSE

Wider breast cancer (BC) treatment options, short consultation time with physicians, lack of knowledge, and poor coping skills at the time of diagnosis may affect patients' decisions causing treatment delays and non-adherence. To address this gap, a breast care nurse video orientation program was started. Our aim was to evaluate the video on patients' knowledge, satisfaction, and treatment adherence.

METHODS

The video was developed using the BC delay explanatory model. A self-administered pre- and post-survey on 241 newly diagnosed BC patients in University Malaya Medical Center was performed. The Wilcoxon matched paired signed rank test was used to evaluate patients' pre and post perceived knowledge using a Likert scale 0 to 4 (0 = "no knowledge," 4 = "a great degree of knowledge"). Treatment adherence among participants were measured after 1-year follow-up.

RESULTS

Eighty percent of the patients reported that the video met or exceeded their expectations. In total 80.5% reported that the video was very effective and effective in improving their perspective on BC treatments. There was improvement in perceived knowledge for treatment options (mean scores; M = 0.93 versus M = 2.97) (p < 0.001) and also for perceived knowledge on types of operation, information on chemotherapy, radiotherapy, hormone therapy, healthy diet, physical activity after treatments, and care of the arm after operation(p < 0.001). In total 89.4%, 79.3%, and 85.9% adhered to surgical, chemotherapy, and radiotherapy recommended treatment, respectively.

CONCLUSION

The video improved patients' perceived knowledge and satisfaction. The program improved access not only to new BC patients but also the public and found sustainable using the YouTube platform.

The Use of Real-World Evidence for Oral Chemotherapies in Breast Cancer

Almost all patients with breast cancer will eventually receive chemotherapy drugs, the majority of which are administered as IV infusions. Real-world evidence indicates that while current treatment paradigms vary considerably from guideline recommendations, there is an increasing trend towards a preference for oral oncolytics among patients with breast cancer. Recent data have shown that oral anticancer therapeutics represent 25% of the oncology drug market share and that there is a high demand for these agents. Therefore, oral formulations of chemotherapy agents such as paclitaxel are currently under development. Although oral oncolytics are associated with several advantages over conventional intravenous drugs, maintaining adherence to therapy is a major barrier in achieving improved outcomes with these agents. Advanced practitioners can facilitate improved adherence to oral oncolytics by integrating evidence into practice to support better education and communication strategies to address patient concerns, overcome key hurdles, and ultimately, empower patients.

The Association Between Cardiac Mortality and Adjuvant Radiation Therapy Among Older Patients With Stage I Estrogen Positive Breast Cancer: A Surveillance, Epidemiology, and End Results (SEER)-Based Study on Cardiac Mortality and Radiation Therapy

PURPOSE

We evaluated the risk of cardiac mortality in older patients who receive adjuvant radiation therapy (RT) for stage I breast cancer to determine whether this risk persists in the modern era.

METHODS AND MATERIALS

Using the 2000 to 2015 Surveillance, Epidemiology, and End Results program data, we performed a population-based cohort study to evaluate the association between adjuvant breast RT, tumor laterality, and cardiac-specific survival (CSS) among patients 60 and older with stage I estrogen receptor positive breast cancer who received breast-conserving surgery and RT.

RESULTS

At a median follow-up of 6 years (range, 0-15.9 years), patients receiving RT for left-sided breast cancer demonstrated no difference in 5- and 10-year CSS compared with those with right-sided breast cancer (5 year 98.3% vs 98.2%, 10 year 94.3% vs 93.9%; log-rank P = .56). Cox proportional hazards regression analysis confirmed the lack of association of tumor laterality on adjusted 5-year CSS (hazard ratio [HR] = 0.96; 95% confidence interval [CI] = 0.87-1.06), breast-cancer specific survival (HR = 0.96; 95% CI = 0.85-1.09), and overall survival (HR = 0.98; 95% CI = 0.94-1.03). There was also no association of inner versus outer quadrant location on adjusted 5-year CSS for right-sided (HR = 1.06; 95% CI = 0.89-1.12) and left-sided breast cancer (HR = 0.95; 95% CI = 0.79-1.15).

CONCLUSIONS

With modern radiation therapy techniques, older patients who received left-sided RT for stage I estrogen-receptor positive breast cancer do not demonstrate an increased risk of cardiac mortality compared with patients with right-sided breast cancer. RT can be offered to older patients without concern for inducing cardiac-related death.

Ten-Year Single Institutional Analysis of Geographic and Demographic Characteristics of Patients Treated With Stereotactic Body Radiation Therapy for Localized Prostate Cancer

Objectives

Stereotactic Body Radiation Therapy (SBRT) offers definitive treatment for localized prostate cancer with comparable efficacy and toxicity to conventionally fractionated radiotherapy. Decreasing the number of treatment visits from over 40 to five may ease treatment burden and increase accessibility for logistically challenged patients. Travel distance is one factor that affects a patient’s access to treatment and is often related to geographic location and socioeconomic status. In this study, we review the demographic and geographic factors of patients treated with SBRT for prostate cancer for a single institution with over a decade of experience.

Methods

Patient zip codes from one thousand and thirty-five patients were derived from a large, prospectively maintained quality of life database for patients treated for prostate cancer with SBRT from 2008 to 2017. The geospatial distance between the centroid of each zip code to our institution was calculated using the R package Geosphere. Characteristics for seven hundred and twenty-one patients were evaluated at the time of analysis including: race, age, and insurance status. To assess the geographic reach of our institution, we evaluated the demographic features of each zip code using US Census data. Statistical comparisons for these features and their relation to distance traveled for treatment was performed using the Mann-Whitney U test. Finally, an unsupervised learning algorithm was performed to identify distinct clusters of patients with respect to median income, racial makeup, educational level, and rural residency.

Results

Patients traveled from 246 distinct zip codes at a median distance of 11.35 miles. Forty percent of patients were African American, 6.9% resided in a rural region, and 22% were over the age of 75. Using K-means cluster analysis, four distinct patient zip-code groups were identified based on the aforementioned demographic features: Suburban/high-income (45%), Urban (30%), Suburban/low-income (17%), and Rural (8%). For each of the clusters, the average travel distance for SBRT was significantly different at 11.17, 9.26, 11.75, and 40.2 miles, respectively (p-value: <0.001).

Conclusions

Distinct demographic features are related to travel distance for prostate SBRT. In our large cohort, travel distance did not prevent uptake of prostate SBRT in African American, elderly or rural patient populations. Prostate SBRT offers a diverse population modern treatment for their localized prostate cancer and particularly for those who live significant distances from a treatment center.

Lower Patient Anxiety and Unchanged Levels of Adherence to Hemato-Oncologic Treatment in Response to New Measures to Reduce Hospital Exposure Risk to COVID-19

OBJECTIVE

Hemato-oncology patients are at high risk for morbidity and mortality from coronavirus disease (COVID-19). The resultant heightened anxiety among these patients may negatively affect adherence to therapy and treatment-related outcome. We aimed to assess whether the adoption of precautionary measures provided by the medical team led to a reduction in COVID-19-related anxiety and, consequently, to successful execution of treatment plans.

METHODS

All adult hemato-oncology patients actively treated or being followed-up at the outpatient service at Tel Aviv Sourasky Medical Center between March 25 and May 3, 2020, were invited to answer a questionnaire that focused on their anxiety and adherence to treatment following new measures to reduce risk of infection during the first COVID-19 outbreak.

RESULTS

One hundred and fifty patients (representing 24% of those being approached), average age 67 years, 52% male, and 57% undergoing antineoplastic therapy, responded to the survey. The introduction of precautionary measures resulted in a significant reduction in anxiety level in all patients, irrespective of age, sex, or treatment status. Attendance to scheduled visits in day care and outpatient clinics remained unchanged. Adherence to planned blood and imaging tests were 81% and 73%, respectively, and 93% of the patients were satisfied with their medical care. Thirty-two percent of patients used telemedicine. Satisfaction with telemedicine was highest among non-actively treated patients and those experiencing high anxiety levels.

CONCLUSION

Reorganization of the hemato-oncology unit and provision of information to patients reduced COVID-19-related anxiety and enabled the same delivery of therapy as that prior to the pandemic.

Bidirectional information sharing between Nagoya Memorial Hospital and health insurance pharmacies using a communication sheet for pharmaceutical cooperation

Background

We collaborated with the regional pharmaceutical associations near Nagoya Memorial Hospital and created a communication sheet for pharmaceutical cooperation between the hospital and health insurance pharmacies.

Methods

The communication sheet for pharmaceutical cooperation was issued in October 2014. We conducted a questionnaire survey of both cancer patients and community pharmacists 1 year after the implementation of the use of this sheet. Based on the results of the survey, we modified our communication sheet and added a unified reply form in October 2016. We examined the number of replies from community pharmacists from October 2014 to April 2019. We then analyzed how community pharmacists instructed and communicated with cancer patients using the results of both the questionnaire survey and the reply form, which were compared before and after introducing the modified version of the communication sheet.

Results

During the 5 years of observation, 743 communication sheets were sent from Nagoya Memorial Hospital to community pharmacists. As a result of pharmaceutical cooperation in using the communication sheet, 96.4% of prescribed medication were immediately prepared in health insurance pharmacies on that day. The communication sheet also enhanced the conversations between cancer patients and pharmacists. The introduction of the unified reply form increased the response rate of community pharmacists from 1.7 to 69.5% (p < 0.001). The communication between community pharmacists and cancer patients was significantly hindered by prescriptions without an oral cancer drug and patient age < 65 years old (p < 0.05). However, this hindrance was reduced by the use of the modified form.

Conclusions

The communication sheet for pharmaceutical cooperation is useful for bidirectional information sharing between hospitals and health insurance pharmacies, which may enable pharmacists to provide cancer patients with medication instructions in coordination with hospitals and increase the quality of outpatient pharmacy services.

The Evolving Complexity of Treating Hormone Receptor-Positive, Human Epidermal Growth Factor Receptor-2 (HER2)-Negative Breast Cancer: Special Considerations in Older Breast Cancer Patients-Part II: Metastatic Disease

Breast cancer is a disease of aging, and the incidence of breast cancer is projected to increase dramatically as the global population ages. The majority of breast cancers that occur in older adults are hormone-receptor positive, human epidermal growth factor receptor-2 (HER2)-negative phenotypes, with favorable tumor biology; yet, because of underrepresentation in clinical trials, less evidence is available to guide the complex care for this population. Providing care for older patients with metastatic breast cancer, with coexisting medical conditions, increased risk of treatment toxicity, and frailty, remains a clinical challenge in oncology. In this review, we provide an overview of the current evidence from clinical trials and subanalyses of older adults with hormone receptor-positive, HER2-negative metastatic breast cancer, highlighting data on the safety and efficacy of oral therapies, including endocrine therapy alone or in combination with cyclin-dependent kinase (CDK) 4/6 inhibitors, phosphatidylinositol 3-kinase (PI3K) inhibitors, and mammalian target of rapamycin (mTOR) inhibitors. In addition, we note the significant underrepresentation of older and frail adults in these studies. Current and future directions in research for this special population, in order to address significant knowledge gaps, include the need to improve long-term adherence to hormonal and targeted therapy, prospective clinical trials that capture clinical and biological aging endpoints, and the need for a multidisciplinary approach with integration of geriatric and oncology principles.

Application of Extrusion-Based 3D Printed Dosage Forms in the Treatment of Chronic Diseases

Chronic disease management has been a significant burden in many countries. As most treatment options involve long-term pharmacotherapy, patient compliance has been a challenge, as patients have to remember taking medications on time at the prescribed dose for each disease state. Patients are often required to split the dosage unit, which may lead to under- or over-dose and dose-related adverse effects. However, 3D printing technologies have been used for fabricating personalized medications and multiple drugs in a single dose unit (polypills), which might greatly reduce treatment monitoring, dosing errors, and follow-ups with the health care providers. Extrusion-based 3D printing is the most used technology to fabricate polypills and to customize the dose, dosage form, and release kinetics, which might potentially reduce the risk of patient non-compliance. Although extrusion-based 3D printing has existed for some time, interest in its potential to fabricate dosage forms for treating chronic diseases is still in its infancy. This review focuses on the various extrusion-based 3D printing technologies such as fused deposition modeling, pressure-assisted microsyringe, and direct powder extrusion 3D printing in the preparation of customizable, multi-drug dosage forms for treating chronic diseases.

Self-reported medication adherence in differentiated thyroid cancer survivors: Role of illness perception and medication beliefs

BACKGROUND

To investigate medication adherence (MA) to Levothyroxine in differentiated thyroid cancer survivors and analyze the related factors for nonadherence.

METHODS

The Medication Adherence Report Scale (MARS), Hospital Anxiety and Depression Scale (HAD), Brief Illness Perception Questionnaire (B-IPQ), and Beliefs about Medicines Questionnaire (BMQ) were used to assess MA.

RESULTS

Nonadherence was reported in 77 of 197 patients (39.1%). Socioeconomic status and education levels were found to be significantly related to MA. The HAD scores, all items of B-IPQ, and BMQ were associated with MA and showed a correlation with the MARS scores. The primary predictors of MA were greater confidence in treatment modality (odds ratio [OR]: 0.48, 95% confidence interval (CI): 0.37-0.63) and greater belief that the medication had minimal risk of harm (OR: 3.35, 95% CI: 1.50-7.49).

CONCLUSIONS

Special attention should be paid to educational programs for differentiated thyroid carcinoma patients concerning the effectiveness and low risk of harm of medication in order to improve MA.

Engineered PLGA microparticles for long-term, pulsatile release of STING agonist for cancer immunotherapy

Activation of the stimulator of interferon gene (STING) pathway within the tumor microenvironment has been shown to generate a strong antitumor response. Although local administration of STING agonists has promise for cancer immunotherapy, the dosing regimen needed to achieve efficacy requires frequent intratumoral injections over months. Frequent dosing for cancer treatment is associated with poor patient adherence, with as high as 48% of patients failing to comply. Multiple intratumoral injections also disrupt the tumor microenvironment and vascular networks and therefore increase the risk of metastasis. Here, we developed microfabricated polylactic-co-glycolic acid (PLGA) particles that remain at the site of injection and release encapsulated STING agonist as a programmable sequence of pulses at predetermined time points that mimic multiple injections over days to weeks. A single intratumoral injection of STING agonist-loaded microparticles triggered potent local and systemic antitumor immune responses, inhibited tumor growth, and prolonged survival as effectively as multiple soluble doses, but with reduced metastasis in several mouse tumor models. STING agonist-loaded microparticles improved the response to immune checkpoint blockade therapy and substantially decreased the tumor recurrence rate from 100 to 25% in mouse models of melanoma when administered during surgical resection. In addition, we demonstrated the therapeutic efficacy of STING microparticles on an orthotopic pancreatic cancer model in mice that does not allow multiple intratumoral injections. These findings could directly benefit current STING agonist therapy by decreasing the number of injections, reducing risk of metastasis, and expanding its applicability to hard-to-reach cancers.

Conversations and Misconceptions About Chemotherapy in Arabic Tweets: Content Analysis

Background

Although chemotherapy was first introduced for the treatment of cancer more than 60 years ago, the public understanding and acceptance of chemotherapy is still debatable. To the best of our knowledge, no study has assessed the conversations and misconceptions about chemotherapy as a treatment for cancer on social media platforms among the Arabic-speaking populations.

Objective

The aim of this study was to assess the types of conversations and misconceptions that were shared on Twitter regarding chemotherapy as a treatment for cancer among the Arabic-speaking populations.

Methods

All Arabic tweets containing any of the representative set of keywords related to chemotherapy and written between May 1, 2017 and October 31, 2017 were retrieved. A manual content analysis was performed to identify the categories of the users, general themes of the tweets, and the common misconceptions about chemotherapy. A chi-square test for independence with adjusted residuals was used to assess the significant associations between the categories of the users and the themes of the tweets.

Results

A total of 402,157 tweets were retrieved, of which, we excluded 309,602 retweets and 62,651 irrelevant tweets. Therefore, 29,904 tweets were included in the final analysis. The majority of the tweets were posted by general users (25,774/29,904, 86.2%), followed by the relatives and friends of patients with cancer (1913/29,904, 6.4%). The tweets were classified into 9 themes; prayers and wishes for the well-being of patients undergoing chemotherapy was the most common theme (20,288/29,904, 67.8%), followed by misconceptions about chemotherapy (2084/29,904, 7.0%). There was a highly significant association between the category of the users and the themes of the tweets (χ²₄₀= 16904.4, P<.001).

Conclusions

Our findings support those of the previous infodemiology studies that Twitter is a valuable social media platform for assessing public conversations, discussions, and misconceptions about various health-related topics. The most prevalent theme of the tweets in our sample population was supportive messages for the patients undergoing chemotherapy, thereby suggesting that Twitter could play a role as a support mechanism for such patients. The second most prevalent theme of the tweets in our study was the various misconceptions about chemotherapy. The findings of our exploratory analysis can help physicians and health care organizations tailor educational efforts in the future to address different misconceptions about chemotherapy, thereby leading to increased public acceptance of chemotherapy as a suitable mode of treatment for cancer.

Effect of the Porosity, Roughness, Wettability, and Charge of Micro-Arc Coatings on the Efficiency of Doxorubicin Delivery and Suppression of Cancer Cells

Porous calcium phosphate coatings were formed by the micro-arc oxidation method on the surface of titanium for the loading and controlled release of the anticancer drug doxorubicin. The coatings’ morphology and microstructure were examined by scanning electron microscopy. The phase composition was determined with the help of X-ray diffraction analysis. Studies of the hydrophilic properties of the coatings and their zeta potential were carried out. Data on the kinetics of doxorubicin adsorption-desorption were obtained. In addition, the effect of calcium phosphate coatings impregnated with doxorubicin on the viability of the Neuro-2a cell line was revealed. The coating formed at low voltages of 200–250 V contained a greater number of branched communicating pores, and therefore they were able to adsorb a greater amount of doxorubicin. The surface charge also contributes to the process of the adsorption-desorption of doxorubicin, but this effect is not fully understood and further studies are required to identify it.

Decision-making in cancer care for people living with dementia

OBJECTIVE

Increasing numbers of people are expected to live with comorbid cancer and dementia. Cancer treatment decision-making for these individuals is complex, particularly for those lacking capacity, requiring support across the cancer care pathway. There is little research to inform practice in this area. This ethnographic study reports on the cancer decision-making experiences of people with cancer and dementia, their families, and healthcare staff.

METHODS

Participant observations, informal conversations, semi-structured interviews, and medical note review, in two NHS trusts. Seventeen people with dementia and cancer, 22 relatives and 19 staff members participated.

RESULTS

Decision-making raised complex ethical dilemmas and challenges and raised concerns for families and staff around whether correct decisions had been made. Whose decision it was and to what extent a person with dementia and cancer was able to make decisions was complex, requiring careful and ongoing consultation and close involvement of relatives. The potential impact dementia might have on treatment understanding and toleration required additional consideration by clinicians when evaluating treatment options.

CONCLUSIONS

Cancer treatment decision-making for people with dementia is challenging, should be an ongoing process and has emotional impacts for the individual, relatives, and staff. Longer, flexible, and additional appointments may be required to support decision-making by people with cancer and dementia. Evidence-based decision-making guidance on how dementia impacts cancer prognosis, treatment adherence and efficacy is required.

Understanding Barriers to Oral Therapy Adherence in Adults With Acute Myeloid Leukemia

Acute myeloid leukemia (AML) is a disease of older adults, with a median age at diagnosis of 68 years. The availability of oral anticancer medications has increased, although the standard treatment for AML remains in intravenous form. We aim to identify barriers to adherence to oral medications in patients with AML and proposed solutions for improvements. Following institutional review board approval, patients with AML and their caregivers were recruited to participate in focus groups. Sessions were digitally recorded, transcribed verbatim, and analyzed for thematic content using Dedoose qualitative software. 11 patients (five < 65 years; six ≥ 65 years) and 4 caregivers participated in these sessions. Three central themes emerged: 1) medication adherence challenges, 2) managing an oral adherence plan, and 3) strategies to improve oral adherence. Participants recommended written schedules, taking medications around meals, and using pillboxes and alarms. We believe that patients are an important source of insight into barriers and solutions to oral medication adherence.

Treatment guidelines of metastatic colorectal cancer in older patients from the French Society of Geriatric Oncology (SoFOG)

BACKGROUND

Several guidelines dedicated to metastatic colorectal cancer (mCRC) are available. Since 2013 no recent guidelines are specifically dedicated to older patients and based on a systematic review.

MATERIALS AND METHODS

A multidisciplinary Task Force with digestive oncologists, geriatricians and methodologists from the SoFOG was formed in 2016 to update recommendations on medical treatment of mCRC based on a systematic review of publications from 2000 to 2018. Search strategy has followed a standardized protocol from the formulation of clinical questions and definition of a search algorithm to the selection of complete articles for recommendations.

RESULTS

The four selected key questions were: For which older patients with mCRC can we considered: (1) Any chemotherapy, (2) Mono or poly-chemotherapy, (3) Anti-angiogenic therapy, (4) Other targeted therapy. Main recommendations for older patients are: (1) Omission of chemotherapy should be discussed with a geriatrician for patients with severe comorbidities, advanced dementia, uncontrolled psychiatric disorder or severe loss of autonomy. (2) If tumor response is not the main aim, a mono-chemotherapy with 5-fluorouracil combined with bevacizumab is recommended as first-line. (3) For patients with symptoms related to metastases or with a planned metastasis ablation, a doublet chemotherapy combined with bevacizumab or anti-EGFR antibody in the context of a RAS wild type tumor is recommended as first-line. Preliminary data suggest that regorafenib may be used, in its registered indication, in patients under 80 with a performance status of 0 and no autonomy alterations and that trifluridine-tipiracil may be used with a tight supervising of hematological function.

What do we really know about the role of caffeine on urinary tract symptoms? A scoping review on caffeine consumption and lower urinary tract symptoms in adults

AIMS

The purpose of this scoping review was to map out the existing literature on caffeine intake and lower urinary tract symptoms (LUTS) in adults.

METHODS

In this scoping review, we searched for all studies available until June 2019 in MEDLINE, Embase, CINAHL, Cochrane Central Register, PsycINFO, LILACS, LiSSa, Web of Science, and Joanna Briggs Institute electronic databases, in addition to a hand search of the bibliographies of all relevant articles and a gray literature search. Both intervention studies on the effects of caffeine reduction in adults with LUTS and observational studies on the association between caffeine intake and LUTS-related outcomes in adults were included and assessed for methodological quality by two independent reviewers.

RESULTS

Fourteen intervention and 12 observational studies were included. Overall, there was a decrease in urgency episodes (level of evidence 2, grade of recommendation B) and nocturnal enuresis episodes (4, C) with caffeine reduction. Observational studies reported an unclear association between caffeine intake and LUTS-related outcomes. Most importantly, this present review highlighted high heterogeneity in the studied populations, caffeine measures, and reported outcomes. There was also unknown or high risk of bias in most identified studies.

CONCLUSIONS

Caffeine reduction appears to reduce LUTS. Future studies on caffeine reduction interventions should target populations with urgency and urge urinary incontinence, which show the most promising results, and include valid and reliable measures of caffeine intake and LUTS. Finally, future studies should also use reporting guidelines to ensure lower risk of bias.

Comprehensive geriatric assessment is correlated to overall survival among gynaecologic oncology patients

OBJECTIVE

To investigate the correlation of comprehensive geriatric assessment to overall survival among older gynaecologic oncology patients.

METHODS

Between 2011 and 2017, patients >70 years had geriatric assessment before treatment. Geriatric assessment included the following tests: Old American resource and services, instrumental activities of daily living, modified Barthels index, mini-mental state examination, geriatric depression scale, mini-nutritional assessment, risk of falling and medication use. Overall survival was calculated for patients' groups below and above median tests scores. Univariate as well as multivariate analysis was done to evaluate the association between each variable and survival.

RESULTS

About 120 patients had geriatric assessment. Mean patients' age was 76.4 ± 5. A total of 78 Patients had ovarian cancer, 16 uterine cancer, 17 cervical cancer and 9 had other gynaecologic malignancies. No correlation was found between age, BMI (body mass index) and cancer type to overall survival. Patients with scores below cut-off values of modified Barthels index, instrumental activities of daily living, mini-nutritional assessment and mini-nutritional assessment had significantly shorter overall survival (P = 0.004, 0.031, 0.046 and 0.004, respectively). This remained significant in both univariate and multivariate analysis.

CONCLUSIONS

Gynaecologic oncology patients with lower geriatric assessment scores have significantly lower overall survival, irrespective of cancer type. Geriatric assessment tests allow objective assessment of older patients with worst prognosis before treatment planning.

Medication Adherence, Health Care Utilization, and Costs Among Patients Initiating Oral Oncolytics for Multiple Myeloma or Chronic Lymphocytic Leukemia/Small Lymphocytic Lymphoma

BACKGROUND

Oral oncolytic therapies have improved survival in hematologic cancers, such as chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) and multiple myeloma (MM), which are now being managed like chronic conditions. However, compared with other cancers, there is a lack of studies assessing adherence, health care resource utilization, and costs in patients with these cancers.

OBJECTIVE

To assess factors associated with adherence to oral oncolytic therapies, health care utilization, and costs in patients with CLL/SLL or MM.

METHODS

A retrospective database study was conducted using the IBM MarketScan Commercial Claims and Medicare Supplement databases. Adults (aged ≥ 18 years) diagnosed with and prescribed an oral oncolytic for CLL/SLL (ibrutinib or idelalisib) or MM (thalidomide, lenalidomide, or pomalidomide) between 2013 and 2016 and with continuous eligibility 6 months before and 12 months after oral oncolytic initiation were identified. Adherence to oral oncolytics was measured using the proportion of days covered (PDC) metric. Multiple linear regression and multivariable logistic regression were used to identify adherence predictors. Count models assessed the relationship between adherence and resource utilization, and generalized linear models assessed the relationship between adherence and health care costs.

RESULTS

A total of 701 and 2,385 patients were identified with CLL/SLL or MM, respectively. Mean PDC (SD) for CLL/SLL and MM patients was 75.3 (22.5) and 57.6 (26.5), respectively. For CLL/SLL patients, those aged ≥ 65 years (beta [B] = -4.00) had lower medication use. Among MM patients, multiple predictors of higher medication use emerged: aged ≥ 65 years (B = 3.44), higher than average outpatient resource utilization (B = 3.53), insurance plan other than preferred provider organization (PPO; B = -2.58), previous cancer therapy (B = -2.81), higher number of concurrent unique therapeutic classes (B = -0.35), and higher comorbidity burden (B = -2.55). Patients with CLL/SLL and enrolled in plans other than a PPO were more likely to be adherent (OR = 1.41, 95% CI = 1.01-1.98), whereas patients who were aged ≥ 65 years, were residents of the southern United States, and had visited the emergency department in the baseline period were less likely to be adherent. For MM patients, those aged ≥ 65 years (OR = 1.68, 95% CI = 1.38-2.04) and with higher than average outpatient services utilization (OR = 1.24, 95% CI = 1.01-1.52) were more likely to be adherent, whereas those enrolled in plans other than a PPO, previously treated with cancer therapy, and with higher comorbidity burden were less likely to be adherent. In both cohorts, adherent patients had significantly lower odds of health care utilization and incurred lower medical costs, but higher prescription costs, following oncolytic initiation; however, total costs were not significantly lower in those adherent.

CONCLUSIONS

Factors were identified that influenced adherence at the patient, treatment, and health system levels. These factors can be used to identify patients requiring interventions for improving medication-taking behavior and associated health care burden.

DISCLOSURES

This study received no outside funding. Dashputre was recently employed by Novartis; K. Gatwood has received speaker fees from Jazz Pharmaceuticals; and J. Gatwood has received research funding from Merck & Co. and GlaxoSmithKline, unrelated to this study..

Prognostic factors of adjuvant chemotherapy discontinuation among stage III colon cancer patients: A survey of medical oncologists and a systematic review and meta-analysis

Background

Factors that are prognostic of early discontinuation of adjuvant chemotherapy among stage III colon cancer patients have yet to be described. To address this gap, a survey of medical oncologists and a systematic review and meta‐analysis were conducted.

Methods

A survey was distributed in March 2019 to medical oncologists who treat colon cancer within Alberta, Canada. Clinicians were asked to rank the prognostic importance of a set of variables using a Likert scale and agreement was quantified using a weighted Cohen's kappa. In addition, we systematically searched four databases up to July 2019. Meta‐analyses were conducted using a random‐effects model.

Results

Of the 25 clinicians who were sent the survey, 14 responded. Overall, there was no agreement regarding which variables were prognostic of early discontinuation (weighted Cohen's kappa = 0.12; 95% CI = 0.05‐0.18). From an initial 3927 articles, 18 investigations were identified for inclusion in our review. Based upon evidence from both the survey and the systematic review, the following four variables were identified as being prognostic of early discontinuation: (a) comorbidity (OR_{2+ vs 0} = 1.53; 95% CI = 1.30‐1.79); (b) performance status (OR_{ECOG 2+ vs 0‐1} = 1.33; 95%CI = 1.07‐1.65); (c) T stage (OR_{T4 vs T1‐2} = 1.57; 95% CI = 0.99‐2.50); and (d) chemotherapy regimen (estimates not pooled due to heterogeneity). In addition to these factors, there was some suggestion that age, marital status/social support, muscle mass, N stage, and tumor grade had prognostic value.

Conclusions

Current evidence is heterogeneous and limited. Additional research is needed to confirm our findings and to explore additional prognostic factors.

The role of Internet cancer information for older adults with cancer: Perspectives of older adults and healthcare professionals

OBJECTIVE

Older adults with cancer have unique information and supportive care needs. There is a growing body of literature regarding the use of Internet health information, but less is known about the use of the Internet for cancer information amongst older adults with cancer.

MATERIALS AND METHODS

This is a secondary analysis of qualitative data from a mixed-methods study of the use of cancer-related Internet information amongst adults with cancer. In the present study, we include transcripts from two samples: 34 interviews with adults over age 55 (n = 17) with cancer, and interviews and focus groups with healthcare professionals (n = 21). Data were analysed using thematic analysis with an interest in age-related themes.

RESULTS

Our findings are grouped into three main themes: (a) independently augmenting healthcare services and supports; (b) supporting and situating information; and (c) mobilising family and support networks. Patients and healthcare providers described cancer-related Internet information as a beneficial resource to address gaps in information and supplement information from healthcare professionals from diagnosis and throughout treatment. Older adults reported using cancer-related Internet information to manage their cancer experience, although sometimes feeling technologically hesitant. However, healthcare professionals felt older adults were less likely than younger patients to seek cancer information from the Internet.

CONCLUSION

The use of cancer-related Internet information is growing amongst older adults with cancer. Older adults mobilise technology uniquely. Healthcare professionals can support these efforts by being aware and through initiating dialogue about information preferences.

A Brief Metric Framework for Patient Adherence to Doctor's Advice Based on Behavioral Economics

PURPOSE

This study tried to establish a metric framework of patient adherence to doctor's advice based on the expected utility and prospect theories, and it explained why the key to patient adherence to doctor's advice is patients' perceptions.

METHODS

Our framework is primarily based on two mature theories: expected utility theory and prospect theory. We started with a basic assumption: the doctor is rational and cares for patient's health utility. We analyzed the expected utility of therapy with a definite diagnosis. Then, we considered the impacts of the accuracy of diagnostic techniques. After that, we explored the patient's response to the doctors' advices based on behavioral economics. In addition, we launched a discrete choice experiment to test our main point: perception is the key to patients' adherence. A total of 200 undergraduate students participated in the discrete choice experiment.

RESULTS

Three main factors might impact a rational clinical decision: the therapeutic and side effects of the treatment, patient's true disease risk, and diagnostic accuracy. However, another factor, patient's individual percepion, was crucial for patient's adherence since it may bias the patient's estimations regarding the above three factors. As a result, doctors and patients would have a cognitive gap in the estimation of the disease and the treatment.

CONCLUSION

The results indicate that without the necessary information, better clinical techniques may not help to improve patient adherence, which support our theoretical reasoning forcefully. Therefore, improving patient adherence should be more of a process of empathy and communication rather than a promotion of medical technology.

Factors influencing medication-taking behaviour with adjuvant endocrine therapy in women with breast cancer: A qualitative systematic review

AIMS

To explore the experience and feelings associated with the endocrine therapy treatment trajectory in women with breast cancer and what affects medication taking behaviour.

DESIGN

Qualitative systematic review.

DATA SOURCES

Qualitative studies were extracted from PubMed, EMBASE, CINAHL, PsycINFO from inception of each database until February 2019.

REVIEW METHODS

The systematic search method SPIDER (sample, phenomenon of interest, design, evaluation, research type) was used. Thematic synthesis of the qualitative data was used.

RESULTS

A total of 478 were identified in the initial search. Only 17 articles met inclusion criteria and were included in this review. Five analytical themes and 17 descriptive subthemes were identified.

CONCLUSIONS

The systematic review highlights knowledge, balancing the scales, self-efficacy and support influence medication taking behaviour to women with breast cancer.

IMPACT

The medication taking behaviour of breast cancer women can be classified into four types: acceptance/persistence, bearing/suffering, hesitation/adjustment, refusing/abandoning. The four types can switch from one to another. Medication taking behaviour is affected by knowledge, balancing the scales, self-efficacy, and support. The medical institutions, communities, and families can gain knowledge of the treatment experiences of women to better understand medication taking behaviour and those at risk for non-adherence. Women wanted different types and amounts of information. Healthcare providers should be aware of patient preferences and take targeted interventions to help them receive treatment.

Metastatic behavior and overall survival according to breast cancer subtypes in stage IV inflammatory breast cancer

BACKGROUND

Distant metastatic disease is frequently observed in inflammatory breast cancer (IBC), with a poor prognosis as a consequence. The aim of this study was to analyze the association of hormone receptor (HR) and human epidermal growth factor receptor-2 (HER2) based breast cancer subtypes in stage IV inflammatory breast cancer (IBC) with preferential site of distant metastases and overall survival (OS).

METHODS

For patients with stage IV IBC, diagnosed in the Netherlands between 2005 and 2016, tumors were classified into four breast cancer subtypes: HR+/HER2-, HR+/HER2+, HR-/HER2+, and HR-/HER2-. Patient, tumor, and treatment characteristics and sites of metastases were compared. OS of the subtypes was compared using Kaplan-Meier curves and the log-rank test. Association between subtype and OS was assessed in multivariable models using logistic regression.

RESULTS

In total, 744 eligible patients were included: 340 (45.7%) tumors were HR+/HER2-, 148 (19.9%) HR-/HER2+, 131 (17.6%) HR+/HER2+, and 125 (16.8%) HR-/HER2-. Bone was the most common metastatic site in all subtypes. A significant predominance of bone metastases was found in HR+/HER2- IBC (71.5%), and liver and lung metastases in the HR-/HER2+ (41.2%) and HR-/HER2- (40.8%) subtypes, respectively. In multivariable analysis, the HR-/HER2- subtype was associated with significantly worse OS as compared to the other subtypes.

CONCLUSION

Breast cancer subtypes in stage IV IBC are associated with distinct patterns of metastatic spread and display notable differences in OS. The use of breast cancer subtypes can guide a more patient-tailored staging directed to metastatic site and extend of disease.

Adherence to Lenalidomide in Older Adults With Newly Diagnosed Multiple Myeloma

INTRODUCTION

One of the most common orally administered antimyeloma agents, lenalidomide, has significantly improved outcomes in multiple myeloma, including in older patients. However, despite its utilization and cost, the rates and factors related to adherence to lenalidomide in older adults with newly diagnosed multiple myeloma remain unknown.

PATIENTS AND METHODS

Data were collected from adults with newly diagnosed multiple myeloma over age 65 years being treated with lenalidomide therapy between the years 2007 and 2014 in the Surveillance, Epidemiology, and End Results (SEER)-Medicare linked databases. Adherence was measured as medication possession ratio (MPR), which was defined as the ratio of the number of days the patient had pills in their possession to the number of days in the observation period in the first year after myeloma diagnosis. MPR of < 90% was considered poor adherence.

RESULTS

A total of 793 patients were included in the analysis. The mean MPR in our cohort was 89.5 ± 9.3%. Overall, 38% (n = 302) of the patients were considered to have poor adherence. Factors associated with poor adherence included increasing age (adjusted odds ratio [aOR] = 1.03 per year; 95% confidence interval [CI], 1.00-1.05; P = .024), black race (aOR = 1.72; 95% CI, 1.08-2.73; P = .022), and polypharmacy (aOR = 1.04 per medication; 95% CI, 1.01-1.08; P = .008).

CONCLUSION

Over a third of older adults with newly diagnosed multiple myeloma were considered to have poor adherence to lenalidomide, using the MPR as a surrogate for adherence. This highlights the need to further understand factors and devise strategies to support adherence in this patient cohort.

Compliance to treatment guidelines and survival in women undergoing interval debulking surgery for advanced epithelial ovarian cancer

BACKGROUND

One of the primary treatment strategies for advanced epithelial ovarian cancers includes neoadjuvant chemotherapy (NACT) followed by interval debulking surgery (IDS) and adjuvant chemotherapy. Compliance to treatment is important to possibly improve outcomes.

AIM

To audit treatment compliance and its effect on overall survival (OS) and disease free survival (DFS) in women undergoing IDS.

METHODS AND RESULTS

Women diagnosed with advanced epithelial ovarian cancer undergoing IDS were included. Details of compliance to chemotherapy and surgery as per standard guidelines were assessed, and correlation with survival was studied. Reasons for protocol deviation at various levels were documented and analysed. A total of 182 patients were included. The total number of deviations was 134 with deviation at any level being 89 (48.9%) and at all levels 5%. Both patient- and treatment-related factors contributed towards deviation. Deviation or noncompliance towards treatment resulted in a significantly reduced 5-year OS (34.4% vs 58.2%; P = .001) compared with compliant patients, which retained its significance on multivariate analysis (P = .024) as well.

CONCLUSION

Deviation from treatment guidelines resulted in a significantly lower 5-year OS compared with those who remained treatment compliant. Both patient- and treatment-related factors contributed towards noncompliance and hence towards lower survival.

Factors associated with endocrine therapy adherence among post-menopausal women treated for early-stage breast cancer in Ontario, Canada

PURPOSE

Adherence to adjuvant endocrine therapy among post-menopausal breast cancer patients is an important survivorship care issue. We explored factors associated with endocrine therapy adherence and survival in a large real-world population-based study.

METHODS

We used health administrative databases to follow women (aged ≥ 66 years) who were diagnosed with breast cancer and started on adjuvant endocrine therapy from 2005 to 2010. Adherence was measured by medical possession ratio (MPR) and characterized as low (< 39% MPR), intermediate (40-79% MPR), or high (≥ 80% MPR) over a 5-year period. We investigated factors associated with adherence using a multinomial logistic regression model. Factors associated with all-cause mortality (5 years after starting endocrine therapy) were investigated using a multivariable Cox proportional hazards model.

RESULTS

We identified 5692 eligible patients starting adjuvant endocrine therapy who had low, intermediate, and high adherence rates of 13% (n = 749), 13% (n = 733), and 74% (n = 4210), respectively. Lower rates of adherence were associated with increased age [low vs. high adherence: odds ratio (OR) 1.03, 95% CI 1.02-1.05 (per year); intermediate vs. high adherence: OR 1.02, 95% CI 1.01-1.04 (per year)]. High adherence was associated with previous use of adjuvant chemotherapy (low versus high adherence OR 0.42, 95% CI 0.30-0.59) and short-term follow-up with a medical oncologist within 4 months of starting endocrine therapy (low versus high adherence OR 0.83, 95% CI 0.69-0.99). Unadjusted analysis showed increased survival among patients with high endocrine therapy adherence. However, an independent association was no longer clearly detected after controlling for confounders.

CONCLUSION

Interventions to improve adjuvant endocrine therapy adherence are warranted. Non-adherence may be a more significant issue among elderly patients. Short-term follow-up visit by a patient's medical oncologist after starting endocrine therapy may help to improve compliance.

Lumpectomy Plus Hormone or Radiation Therapy Alone for Women Aged 70 Years or Older With Hormone Receptor-Positive Early Stage Breast Cancer in the Modern Era: An Analysis of the National Cancer Database

PURPOSE

Deintensification of adjuvant therapy is being considered for older women with early-stage, biologically favorable breast cancer. Although radiation therapy (RT) can be omitted in some cases, toxicity from hormone therapy (HT) is not trivial, and adherence rates vary. We hypothesized that adjuvant RT alone would produce survival outcomes comparable to those with adjuvant HT alone among elderly patients treated with lumpectomy.

METHODS AND MATERIALS

We searched the National Cancer Database (2010-2014) for healthy women (aged ≥70 years, Charlson/Deyo [CD] score 0-1) with T1N0 hormone-receptor-positive, HER-2-negative breast cancer treated with lumpectomy and adjuvant HT or RT. Propensity scores were used to match patients for analysis.

RESULTS

We identified 2995 patients (median age, 78 years), most (81%) with a CD score of 0, clinical stage IA (77%), of whom 65% received HT alone and 35% received RT only after lumpectomy. On multivariate analysis of the matched cohort, older age (hazard ratio [HR] 1.10; 95% confidence interval [CI] 1.07-1.13; P < .001), CD score 1 (HR 1.92; 95% CI 1.37-2.70; P = .0002), and living in a metropolitan (vs urban) area (HR 3.09; 95% CI 1.43-6.67; P = .004) were associated with inferior overall survival (OS), whereas treatment with HT (vs RT) was not (HR 1.13; 95% CI 0.85-1.49; P = .406). At a median follow-up of 45 months, no difference was found in OS between HT versus RT cohorts (85% and 86%, respectively; P = .44).

CONCLUSIONS

For healthy, older women with biologically favorable breast cancer treated with lumpectomy, adjuvant RT or HT is associated with equivalent 5-year OS rates. A randomized controlled trial is warranted to explore these adjuvant monotherapy options in elderly patients with hormone receptor-positive breast cancer.

Surgery in the Older Patient with Breast Cancer

PURPOSE OF REVIEW

Breast cancer incidence and mortality increase with age. Older patients (≥ 70) are often excluded from studies. Due to multiple factors, it is unclear whether this population is best-treated using standard guidelines. Here, we review surgical management in older women with breast cancer.

RECENT FINDINGS

Geriatric assessments can guide treatment recommendations and aid in predicting survival and quality of life. Surgery remains a principal component of breast cancer treatment in older patients, though differences exist compared with younger women, including higher mastectomy rates and evidence-based support of omission of post-lumpectomy radiation or axillary dissection in subsets of patients. In those forgoing surgical management, there is increased use of endocrine therapy. Hospice is also a valuable element of end-of-life care. Physicians should utilize geriatric assessment to make treatment recommendations for older breast cancer patients, including omission of radiation therapy, alterations to standard surgeries, or enrollment in hospice care.

Acuerdos de Riesgo Compartido: Lecciones Para su Diseño e Implementación a la Luz de la Experiencia Internacional

BACKGROUND

Despite the growing interest in risk-sharing agreements as appropriate payment mechanisms for high-cost treatments, few practical resources facilitate their adoption.

OBJECTIVE

To identify and propose lessons for designing and implementing these models based on a review of the international experience, and to offer a concise model based on these lessons.

METHODS

The steps of the Joanna Briggs Institute were adopted, which included identifying the concept and its relevant variants in scientific and gray literature.

RESULTS

Forty-one references were examined in depth. The design of these payment mechanisms should be a process carried out by competent actors (payer, producer, specialists, patients, and a neutral entity); the design must be supported by a sound regulatory and contractual framework that structures its components and clarifies the functions of each actor. Finally, there are critical activities for each actor in each phase of the agreement's progress.

CONCLUSIONS

The participation of all actors and the clarification of critical elements and tasks are fundamental for the optimal development of the experiences.

The role of the pharmacist in improving medication beliefs and adherence in cancer patients

BACKGROUND

Multiple factors have been reported to affect adherence to medication, including beliefs about medicines, while specifically tailored pharmaceutical care services for patients may improve adherence. The aim was to assess the impact of counselling by an oncology pharmacist on patients' medication adherence and beliefs.

METHODS

An interventional prospective study was performed in the oncology department at a tertiary hospital in Northern Cyprus from November 2017 to April 2018. The Beliefs about Medicines Questionnaire was used to evaluate the balance between beliefs about necessity and concerns and medication beliefs before and after an educational intervention. The Morisky Green Levine Test 2018 was used to evaluate adherence.

RESULTS

In total, 81 patients (65.4% females; mean age: 59.1 ± 11.34 years; 34.6% hypertensive; 19.8% with diabetes) were analysed before and after receiving counselling from an oncology pharmacist. Pharmacist education significantly enhanced the mean patient necessity-concern balance scores by two-fold (M_T0(baseline) = -3.1 ± 8.6; M_{T1(posteducation)} =3.0 ± 7.3; p < 0.0001), with patients who received counselling for the first time experiencing the greatest benefit. Multivariate analysis showed that patients who had a negative balance between their beliefs about the necessity of the medication and their concerns were less likely to adhere to the medication (0.138 (0.025-0.772)).

CONCLUSION

Counselling by an oncology pharmacist was effective in decreasing patient concerns and increasing their understanding of the necessity of the medication, thus enhancing their adherence and consequently improving the care they received.

Patient-centered design in developing a mobile application for oral anticancer medications

OBJECTIVES

To develop and test the usability and feasibility of a customizable mobile application (app) designed to help educate patients about their oral anticancer medications (OAMs) and regimens.

SETTING

Outpatient cancer center and oncology pharmacy for urban, Midwestern academic health system.

PRACTICE DESCRIPTION

Clinically-supervised educational intervention to support patients learning about OAMs.

PRACTICE INNOVATION

With input from patient partners, our interdisciplinary team designed the first known tablet-based educational app that can interface with a patient's electronic medical record. The app is based on learning style and adherence theories and is customizable for individually prescribed OAMs. The app can accommodate multiple learning styles through text at 6th-grade reading level, pictures, animations, and audio voiceovers. Functionalities include interactive educational modules on 11 OAMs and case-based patient stories on common barriers to OAM adherence.

EVALUATION

Early phase testing provided the opportunity to observe the user interface with the app and app functionality. Data were summarized descriptively from observations and comments of patient subjects.

RESULTS

Thirty patient subjects provided input-19 in phase 1 usability testing and 11 in phase 2 feasibility testing. Comments provided by patient subjects during usability testing were largely positive. Responses included self-identification with patient stories, usefulness of drug information, preferences for text messages, and app limitations (e.g., perceived generational digital divide in technology use and potential patient inability to receive text messages). Using their feedback, modifications were made to the prototype app. Responses in feasibility testing demonstrated the app's usefulness across a wide range of ages. Highest opinion ratings on app usefulness were stated by patients who were newer to OAM therapy.

CONCLUSION

User feedback suggests the potential benefit of the app as a tool to help patients with cancer, particularly after the first months for those starting new OAM regimens. Processes and lessons learned are transferable to other settings.

Challenges and perceived unmet needs of Chinese migrants affected by cancer: Focus group findings

OBJECTIVES

Chinese migrant cancer survivors and carers face multiple barriers to accessing quality cancer information and support. This study aimed to explore the challenges and unmet needs experienced by the Australian Chinese community affected by cancer, and understand the contexts that hindered optimal care for this community.

METHODS

Adult cancer survivors and carers, whose native language is Mandarin or Cantonese, were recruited through community cancer support organizations. Bilingual researchers conducted focus groups with participants in either Mandarin or Cantonese. Focus groups were audio-recorded, transcribed, translated into English and thematically analyzed using qualitative methods.

FINDINGS

62 Chinese-speaking participants (34 cancer survivors and 28 carers) participated in one of the eight focus groups conducted. The three main themes were (1) unmet information and support needs (trust, wellness, and rights); (2) barriers compounding unmet needs (language, health literacy, culture); and (3) participants' recommendations regarding cancer information and support provision. Seven subthemes of unmet needs were also identified: Trust (e.g., communication barriers, health system barriers, comparison regarding the care received), wellness (e.g., cultural differences produce conflict on views about wellness, need for psychological, community, and spiritual support), and rights (e.g., low awareness of financial and legal assistance, other factors increasing or reducing vulnerability).

CONCLUSIONS

This study highlights the needs and provides new insights into the impact of language, culture and health literacy barriers on the unmet information and support needs of the Chinese community affected by cancer. The key findings will inform the development of culturally targeted information and support resources for this community.

Effectiveness of interventions to improve cancer treatment and follow-up care in socially disadvantaged groups

OBJECTIVE

To identify and characterize the interventions that aimed to improve cancer treatment and follow-up care in socially disadvantaged groups. To summarize the state of the art for clinicians and researchers.

METHODS

We conducted a systematic review following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Eligible studies were randomized controlled trials and quasi-experimental studies with a control group (usual care or enhanced usual care) conducted in Organization for Economic Co-operation and Development (OECD) member countries and published until 2016.

RESULTS

Thirty-one interventions were identified, the majority of which were conducted in the United States in patients with breast cancer. Most interventions aimed to decrease social inequalities based on ethnicity/race and/or socioeconomic level, with fewer interventions targeting inequalities based on geographical area. The most frequently assessed outcomes were quality of life (n = 20) and psychosocial factors (n = 20), followed by treatment adherence or satisfaction (n = 12,), knowledge (n = 11), pain management (n = 10), and lifestyle habits (n = 3).

CONCLUSIONS

The impact of interventions designed to improve cancer treatment and follow-up care in socially disadvantages groups is multifactorial. Multicomponent-intervention approaches and cultural adaptations are common, and their effectiveness should be evaluated in the populations of interest. More interventions are needed from outside the Unite States and in patients with cancers other than breast cancer, targeting gender or geographical inequalities and addressing key outcomes such as treatment adherence or symptom management.

Implementing value assessment in oncology practice: A single-center experience

Cancer treatment costs in the United States are rising. Evidence suggests that increased costs do not always correlate with improved outcomes. Several organizations have developed tools and frameworks to assess cancer treatment value; however, many centers have reported difficulty in implementing these tools and effectively incorporating value-based decision making into clinical practice. After evaluating existing frameworks, the Carbone Cancer Center at UW Health set out to create a value-based tool that could be used to inform the decisions of clinicians and patients. This tool was piloted in metastatic or advanced non-small cell lung cancer, specifically in the second-line setting to assess the value of immune checkpoint inhibitors nivolumab, atezolizumab, and pembrolizumab. The results of the pilot suggest that atezolizumab is the best value of the three agents in this patient population. Challenges and opportunities for improvement that were identified during the pilot process have helped refine the tool for use in a variety of disease states within oncology.

Barriers and Facilitators of Using Sensored Medication Adherence Devices in a Diverse Sample of Patients With Multiple Myeloma: Qualitative Study

Background

Many recently approved medications to manage multiple myeloma (MM) are oral, require supportive medications to prevent adverse effects, and are taken under complex schedules. Medication adherence is a concern; however, little attention has been directed toward understanding adherence in MM or associated barriers and facilitators. Advanced sensored medication devices (SMDs) offer opportunities to intervene; however, acceptability among patients with MM, particularly African American patients, is untested.

Objective

This study aimed to explore patients’ (1) perceptions of their health before MM including experiences with chronic medications, (2) perceptions of adherence barriers and facilitators, and (3) attitudes toward using SMDs.

Methods

An in-person, semistructured, qualitative interview was conducted with a convenience sample of patients being treated for MM. Patients were recruited from within an urban, minority-serving, academic medical center that had an established cancer center. A standardized interview guide included questions targeting medication use, attitudes, adherence, barriers, and facilitators. Demographics included the use of cell phone technology. Patients were shown 2 different pill bottles with sensor technology—Medication Event Monitoring System and the SMRxT bottle. After receiving information on the transmission ability of the bottles, patients were asked to discuss their reactions and concerns with the idea of using such a device. Medical records were reviewed to capture information on medication and diagnoses. The interviews were audio-recorded and transcribed. Interviews were independently coded by 2 members of the team with a third member providing guidance.

Results

A total of 20 patients with a mean age of 56 years (median=59 years; range=29-71 years) participated in this study and 80% (16/20) were African American. In addition, 18 (90%, 18/20) owned a smartphone and 85% (17/20) were comfortable using the internet, text messaging, and cell phone apps. The average number of medications reported per patient was 13 medications (median=10; range=3-24). Moreover, 14 (70%, 14/20) patients reported missed doses for a range of reasons such as fatigue, feeling ill, a busy schedule, forgetting, or side effects. Interest in using an SMD ranged from great interest to complete lack of interest. Examples of concerns related to the SMDs included privacy issues, potential added cost, and the size of the bottle (ie, too large). Despite the concerns, 60% (12/20) of the patients expressed interest in trying a bottle in the future.

Conclusions

Results identified numerous patient-reported barriers and facilitators to missed doses of oral anticancer therapy. Many appear to be potentially mutable if uncovered and addressed. SMDs may allow for capture of these data. Although patients expressed concerns with SMDs, most remained willing to use one. A feasibility trial with SMDs is planned.

Investigation of the relationship among fatigue, self-efficacy and quality of life during chemotherapy in patients with breast, lung or gastrointestinal cancer

To explore the relationship between fatigue and self-efficacy, and quality of life (QoL) during chemotherapy of patients with breast, lung or gastrointestinal cancers. This study is a descriptive-correlational research. The study population comprised of patients with breast, lung and gastrointestinal cancer treated at the outpatient chemotherapy unit. Patients' self-efficacy and QoL were assessed using Functional Assessment of Chronic Illness Therapy-Fatigue scale and Strategies Used by Patients to Promote Health scale. The sample included 236 patients receiving chemotherapy for lung cancer (30.9%), gastrointestinal (25.8%) or breast cancers (25.4%). The patients had little confidence in performing self-care self-efficacy during chemotherapy for the management of illness and chemotherapy-related side effects. The study found that the patients with cancer were moderately fatigued and all the domains of QoL of patients with cancer undergoing chemotherapy were considerably impaired. Positive correlations were found between self-efficacy scores and fatigue scores (p < 0.001), and QoL scores (p < 0.001). Better self-efficacy beliefs were associated with better QoL and lower fatigue. Improving the cancer patients' self-confidence in performing self-care behaviours may have a positive impact on performing cognitive and behavioural fatigue management strategies and can influence positively the patients' QoL during chemotherapy.

A systematic review of the impact of outpatient clinical pharmacy services on medication-related outcomes in patients receiving anticancer therapies

BACKGROUND

Patients receiving anticancer therapies are frequently prescribed complex and high-risk medication regimens, which at times can result in medication misadventures. The objective of this review was to assess the effect of outpatient clinical pharmacy services on medication-related outcomes in patients receiving anticancer therapies, including patients undergoing radiotherapy.

METHODS

A systematic review of original publications indexed in EMBASE, MEDLINE and Cochrane Library from June 2007 to June 2017. Eligible studies evaluated outpatient pharmacy clinic services for cancer patients and reported at least one medication-related quantitative outcome measure. Two authors independently reviewed full-text articles for inclusion, then extracted data and performed quality and risk of bias assessments.

RESULTS

Of 908 identified publications, 13 met predefined eligibility criteria; 1 randomised control trial, 2 controlled cohort studies and 10 uncontrolled before-after studies. Many excluded studies described outpatient pharmacy services but lacked medication-related outcomes. All included studies had informative practice model designs, with interventions for drug-related problems including drug dose optimisation ( n = 8), reduced drug interaction ( n = 6) and adverse drug reaction reporting ( n = 3). Most studies ( n = 11) reported on symptom improvement, commonly nausea ( n = 7) and pain ( n = 5). Of four studies in radiotherapy cohorts, pharmacist involvement was associated with improved symptoms, satisfaction and wellbeing scores.

CONCLUSION

Few studies have objectively assessed outpatient pharmacy cancer services, even fewer in the radiotherapy settings. Although the results support these services, significant heterogeneity and bias in the study designs prohibit robust conclusions and further controlled trials are required.

Preventing Treatment-Related Functional Decline: Strategies to Maximize Resilience

The majority of patients with cancer are older adults. A comprehensive geriatric assessment (CGA) will help the clinical team identify underlying medical and functional status issues that can affect cancer treatment delivery, cancer prognosis, and treatment tolerability. The CGA, as well as more abbreviated assessments and geriatric screening tools, can aid in the treatment decision-making process through improved individualized prediction of mortality, toxicity of cancer therapy, and postoperative complications and can also help clinicians develop an integrated care plan for the older adult with cancer. In this article, we will review the latest evidence with regard to the use of CGA in oncology. In addition, we will describe the benefits of conducting a CGA and the types of interventions that can be taken by the interprofessional team to improve the treatment outcomes and well-being of older adults.

Adherence to Oral Anticancer Medications: Evolving Interprofessional Roles and Pharmacist Workforce Considerations

Interprofessional care is exhibited in outpatient oncology practices where practitioners from a myriad of specialties (e.g., oncology, nursing, pharmacy, health informatics and others) work collectively with patients to enhance therapeutic outcomes and minimize adverse effects. Historically, most ambulatory-based anticancer medication therapies have been administrated in infusion clinics or physician offices. Oral anticancer medications (OAMs) have become increasingly prevalent and preferred by patients for use in residential or other non-clinic settings. Self-administration of OAMs represents a significant shift in the management of cancer care and role responsibilities for patients and clinicians. While patients have a greater sense of empowerment and convenience when taking OAMs, adherence is a greater challenge than with intravenous therapies. This paper proposes use of a qualitative systems evaluation, based on theoretical frameworks for interdisciplinary team collaboration and systems science, to examine the social interactionism involved with the use of intravenous anticancer treatments and OAMs (as treatment technologies) by describing patient, organizational, and social systems considerations in communication, care, control, and context (i.e., Kaplan’s 4Cs). This conceptualization can help the healthcare system prepare for substantial workforce changes in cancer management, including increased utilization of oncology pharmacists.

Adjuvant hormonal therapy for early breast cancer: an epidemiologic study of medication adherence

PURPOSE

The aim of this study was to determine the prevalence of adherence to adjuvant hormonal therapy (AHT) and to identify risk factors for medication non-adherence in clinical practice in patients with early-stage hormone receptor (HR)-positive breast cancer (BC) previously treated with chemotherapy.

METHODS

We carried out a cross-sectional, observational, prospective, and multicenter survey based on a structured self-report postal questionnaire (35 items investigating six areas). A sample of 474 patients was drawn from 676 patients potentially eligible. The structured and validated Morisky Medication Adherence Scale-4 items was used for measuring medication adherence. An analysis of risk factors for non-adherence to AHT was performed using a two-step approach: univariate, then multivariate analysis.

RESULTS

A total of 280 patients out of the 428 analyzed patients participated in the survey, yielding a response rate of 65.4% [60.9-69.9]. The prevalence of adherence to AHT was estimated at 68.6% [63.1-74.0], corresponding to a high level of adherence. Three risk factors for non-adherence to AHT were identified: > 2 medications to treat comorbidities (p-value = 0.003), age less than 65 years (p-value = 0.008), and patient management in a university hospital setting (p-value = 0.014).

CONCLUSIONS

Non-adherence is a common, complex, and multidimensional healthcare problem. This better understanding and knowledge of risk factors will allow healthcare providers (such as oncologists, general practitioners, pharmacists) to more easily identify patients at risk for non-adherence and help them provide appropriate information about AHT and its management, thus improving medication adherence in their patients.

Current Strategies of Endocrine Therapy in Elderly Patients with Breast Cancer

Currently, the growing population of the elderly is one of biggest problems in terms of increase in geriatric diseases. Lack of data from large prospective studies on geriatric breast cancer patients often makes it difficult for clinicians to make treatments decisions for them. Because both benefit and risk of treatment should be taken into account, treatment is usually determined considering life expectancy or comorbidities in elderly patients. Treatment of breast cancer is differentiated according to histologic classifications, and hormone therapy is even adopted for patients with metastatic breast cancer if tumor tissue expresses hormone receptors. Endocrine therapy can offer great benefit to elderly patients considering its equivalent efficacy to chemotherapy with fewer toxicities if it is appropriately used. Aromatase inhibitors are usually prescribed agents in hormone therapy for elderly breast cancer patients due to their physiology after menopause. Here, endocrine therapy for elderly patients with breast cancer in neoadjuvant, adjuvant, and palliative setting is reviewed along with predictive adverse events resulting from the use of hormone agents.

Older Patients' Recall of Online Cancer Information: Do Ability and Motivation Matter More than Chronological Age?

This study proposes and tests a model to provide a more comprehensive understanding of the contribution of chronological age versus age-related ability and motivation factors in explaining recall of online cancer information among older patients (n = 197). Results revealed that recall is not a matter of chronological age per se, but rather a matter of ability and motivation. Age-related ability and motivation factors explained 37.9% of the variance in recall. Health literacy, involvement with the webpage, and satisfaction with the emotional support were positively associated with recall. Furthermore, recall was negatively related to frailty, anger, future time perspective, and perceived cognitive load. The findings pose relevant opportunities for tailoring interventions to improve online information provision for older cancer patients.
