Impact of preexisting mental illness on breast cancer endocrine therapy adherence

Predictors of self-care in patients with cancer treated with oral anticancer agents: A systematic review

BACKGROUND

In the last two decades, the use of oral anticancer agents (OAAs) has increased in cancer patients. Despite this, patients and their caregivers face some challenging issues (side effects, drug-to-drug interactions, etc.) related to OAA administration. The three dimensions of self-care by Riegel et al., self-care maintenance (i.e., stability of patient condition), self-care monitoring (i.e., detection of side effects), and self-care management (i.e., management of side effects), may be implemented to avoid negative outcomes. However, knowledge of self-care determinants is necessary to recognise people at risk of poor self-care behaviours.

AIMS

Determine which are the predictors of self-care maintenance, self-care monitoring and self-care management in patients with cancer taking OAA.

METHODS

A systematic review with narrative synthesis was conducted. We included studies on adult patients with cancer using any kind of oral anticancer agent and describing a predictor of self-care. The search was performed on PubMed, CINAHL/PsycINFO, and Web of Science.

RESULTS

Of 3,061 records, 45 studies were included in this review. Forty-six predictors organised into 14 categories were identified. In general, all studies focused only on adherence, considered as a self-care maintenance component, and none of them focused on other dimensions of self-care. The predictors of OAA adherence most reported were age, side effects, and socioeconomic factors (e.g., insurance status, and annual income).

CONCLUSIONS

This systematic review highlighted the literature gap on the analysis of determinants of self-care behaviours in patients taking OAAs. This element could be a starting point for future research that can provide elements to support the oncology nursing research agenda, aimed at recognising patients at risk of poor self-care.

Cancer characteristics in patients with schizophrenia: a 25-year retrospective analysis

Schizophrenia is associated with higher cancer-related mortality, perhaps due to delayed diagnosis and limited access to treatment. The study aimed to compare patients diagnosed with cancer with and without schizophrenia to determine whether these groups differ in terms of oncological variables and survival outcomes. This was a retrospective, observational cohort study that included 30.990 patients diagnosed with cancer between 1997 and 2021. We performed univariate and bivariate analyses for the sociodemographic and clinical variables, and constructed Kaplan-Meier survival curves and used the log-rank test to perform the comparisons. All variables were compared for each cancer type. One hundred and sixty-two (0.52 %) patients had a confirmed diagnosis of schizophrenia (ICD-9 criteria). The mean age at diagnosis was significantly lower in the schizophrenia group. A significantly higher proportion of the schizophrenia group was diagnosed with cancer through the emergency department and a lower percentage through scheduled appointments. A smaller percentage of patients in the schizophrenia group received radical treatment for cancer. The mortality rate was higher in the schizophrenia group and median survival was lower. These findings suggest that cancer patients with schizophrenia have worse outcomes than patients without schizophrenia in terms of oncological variables and survival.

Elevated neopterin and decreased IL-4, BDNF levels and depression in lymphoma patients receiving R-CHOP chemotherapy

Objective

Depression is the most commonly observed psychological manifestation experienced by individuals diagnosed with cancer. The purpose of the study was to investigate the association between levels of IL-4, BDNF, neopterin, and depressive symptoms in lymphoma patients receiving consecutive cycles of chemotherapy.

Methods

Newly diagnosed lymphoma patients scheduled to receive R-CHOP chemotherapy were enrolled. Effects of R-CHOP on circulatory biomarkers and depressive symptoms were assessed at three-time points [baseline assessment 7 days before the first dose of chemotherapy (TP1), interim assessment after the third cycle of chemotherapy (TP2), and follow-up assessment after the 6th cycle of chemotherapy (TP3)].

Results

Seventy lymphoma patients, with a mean age of 44.17 ± 13.67 years, were enrolled. Patients receiving R-CHOP were found significantly increased neopterin levels between given time points TP1 vs. TP2, TP1 vs. TP3, and TP2 vs. TP3 (p < 0.001). However, IL-4 and BDNF levels significantly decreased with consecutive cycles of chemotherapy (p < 0.001). On Patient Health Questionnaire assessment (PHQ-9), scores of items like loss of interest, feeling depressed, sleep problems, loss of energy, and appetite problems were found significantly affected with consecutive cycles of chemotherapy (p < 0.001). The study found weak negative correlations between IL-4, BDNF, and neopterin levels and changes in PHQ-9 scores at both TP2 and TP3, suggesting a potential inverse relationship between these markers and depression symptoms.

Conclusion

In conclusion, the present study suggests a potential link between elevated neopterin levels, decreased IL-4, and BDNF levels, and the presence of depression in lymphoma patients receiving R-CHOP chemotherapy. This study provides valuable insights into understanding the emotional challenges faced by cancer patients, offering information for more personalized interventions and comprehensive support approaches within the oncology setting.

Disparities in cancer care in individuals with severe mental illness: A narrative review

Individuals with severe mental illness (SMI) have higher mortality rates from cancer than individuals without SMI. The aim of this paper is to highlight these disparities in cancer care in individuals with SMI and suggest potential solutions. We conducted a narrative review of published papers, focusing on mortality, incidence, behavioral and provider risk factors, screening, diagnosis, treatment, and palliative care among individuals with SMI and cancer. The literature does not provide a clear consensus on whether a difference in cancer incidence exists among individuals with SMI compared to the general population. However, it is evident that individuals with SMI have higher mortality from cancer. Factors such as increased cancer related risk behavior, mental health stigma, and difficulty accessing cancer care contribute to this mortality difference. The literature also indicates lower screening rates, delayed and improper diagnosis and treatment, as well as inadequate clinical trial enrollment in individuals with SMI. While the literature is inconclusive regarding disparities in palliative care, we outline key concepts to provide the best possible end of life care to this population. We also summarize strategies to address disparities at the screening, diagnostic, and treatment levels and describe general strategic approaches to improve cancer care in individuals with SMI. We highlight patient-related, physician-related, and healthcare/systems-related factors leading to disparities in cancer care in individuals with SMI. Future research must examine the effectiveness of proposed solutions to guide evidence-based practices.

Association between trajectories of adherence to endocrine therapy and risk of treated breast cancer recurrence among US nonmetastatic breast cancer survivors

BACKGROUND

Endocrine therapy is the mainstay treatment for breast cancer (BC) to reduce BC recurrence risk. During the first year of endocrine therapy use, nearly 30% of BC survivors are nonadherent, which may increase BC recurrence risk. This study is to examine the association between endocrine therapy adherence trajectories and BC recurrence risk in nonmetastatic BC survivors.

METHODS

This retrospective cohort study included Medicare beneficiaries in the United States (US) with incident nonmetastatic BC followed by endocrine therapy initiation in 2010-2019 US Surveillance, Epidemiology, and End Results linked Medicare data. We calculated monthly fill-based proportion of days covered in the first year of endocrine therapy. We applied group-based trajectory models to identify distinct endocrine therapy adherence patterns. After the end of the first-year endocrine therapy trajectory measurement period, we estimated the risk of time to first treated BC recurrence within 4 years using Cox proportional hazards models.

RESULTS

We identified 5 trajectories of adherence to endocrine therapy in BC Stages 0-I subgroup (n = 28,042) and in Stages II-III subgroup (n = 7781). A trajectory of discontinuation before 6 months accounted for 7.0% in Stages 0-I and 5.8% in Stages II-III subgroups, and this trajectory was associated with an increased treated BC recurrence risk compared to nearly perfect adherence (Stages 0-I: adjusted hazard [aHR] = 1.84, 95% CI = 1.46-2.33; Stages II-III: aHR = 1.38, 95% CI = 1.07-1.77).

CONCLUSIONS

Nearly 7% of BC survivors who discontinued before completing 6 months of treatment was associated with an increased treated BC recurrence risk compared to those with nearly perfect adherence among Medicare nonmetastatic BC survivors.

Clinical factors associated with patterns of endocrine therapy adherence in premenopausal breast cancer patients

INTRODUCTION

Patients with hormone receptor positive breast cancer are recommended at least five years of adjuvant endocrine therapy, but adherence to this treatment is often suboptimal. We investigated longitudinal trends in adjuvant endocrine therapy (AET) adherence among premenopausal breast cancer patients and identified clinical characteristics, including baseline comorbidities and non-cancer chronic medication use, associated with AET adherence.

METHODS

We included stage I-III premenopausal breast cancer patients diagnosed during 2002-2011 and registered in the Danish Breast Cancer Group clinical database who initiated AET. We used group-based trajectory modeling to describe AET adherence patterns. We also linked patients to Danish population-based registries and fit multinomial logistic models to compute odds ratios (ORs) and 95% confidence intervals (95% CIs) associating clinical characteristics with AET adherence patterns.

RESULTS

We identified three adherence patterns among 4,353 women-high adherers (57%), slow decliners (36%), and rapid decliners (6.9%). Women with stage I disease (vs. stage II; OR: 1.9, 95% CI 1.5, 2.5), without chemotherapy (vs. chemotherapy; OR: 4.3, 95% CI 3.0, 6.1), with prevalent comorbid disease (Charlson Comorbidity Index score ≥ 1 vs. 0; OR: 1.6, 95% CI 1.1, 2.3), and with a history of chronic non-cancer medication use (vs. none; OR: 1.3, 95% CI 1.0, 1.8) were more likely to be rapid decliners compared with high adherers.

CONCLUSIONS

Women with stage I cancer, no chemotherapy, higher comorbidity burden, and history of chronic non-cancer medication use were less likely to adhere to AET. Taking steps to promote adherence in these groups of women may reduce their risk of recurrence.

Treatment and Mortality Following Cancer Diagnosis Among People With Non-affective Psychotic Disorders in Ontario, Canada: A Retrospective Cohort Study

BACKGROUND AND HYPOTHESIS

People with psychotic disorders have a higher risk of mortality following cancer diagnosis, compared to people without psychosis. The extent to which this disparity is influenced by differences in cancer-related treatment is currently unknown. We hypothesized that, following a cancer diagnosis, people with psychotic disorders were less likely to receive treatment and were at higher risk of death than those without psychosis.

STUDY DESIGN

We constructed a retrospective cohort of cases of non-affective psychotic disorder (NAPD) and a general population comparison group, using Ontario Health (OH) administrative data. We identified cases of all cancers diagnosed between 1995 and 2019 and obtained information on cancer-related treatment and mortality. Cox proportional hazards models were used to compare the probability of having a consultation with an oncologist and receiving cancer-related treatment, adjusting for tumor site and stage. We also compared the rate of all-cause and cancer-related mortality between the two groups, adjusting for tumor site.

STUDY RESULTS

Our analytic sample included 24 944 people diagnosed with any cancer. People with NAPD were less likely to receive treatment than people without psychosis (HR = 0.87, 95% CI = 0.82, 0.91). In addition, people with NAPD had a greater risk of death from any cause (HR = 1.68, 95% CI = 1.60, 1.76), compared to people without NAPD.

CONCLUSIONS

The lower likelihood of receiving cancer treatment reflects disparities in accessing cancer care for people with psychotic disorders, which may partially explain the higher mortality risk following cancer diagnosis. Future research should explore mediating factors in this relationship to identify targets for reducing health disparities.

Compliance with medical regimen among hematological cancer patients and its association with symptoms of posttraumatic stress disorder and adjustment disorder

Background

Hematological cancer patients must comply with extensive medical instructions to prevent cancer progression or relapse. Psychological comorbidities and patient characteristics have been shown to affect compliance. However, the impact of posttraumatic stress disorder (PTSD) and adjustment disorder (AjD) on compliance in cancer patients remains unclear. This study aims to evaluate compliance in hematological cancer patients more comprehensively and to investigate its association with PTSD and AjD symptomatology as well as sociodemographic and medical factors.

Methods

Hematological cancer patients were cross-sectionally assessed via validated questionnaires for PTSD (PCL-5) and AjD (ADMN-20), and three internally developed items on compliance with medical regimen, with two referring to compliance behavior and one item assessing perceived difficulties with complying. Each compliance item was analyzed descriptively. Multiple linear regression models tested the association between compliance and PTSD and AjD symptomatology, sociodemographic and medical factors.

Results

In total, 291 patients were included (response rate 58%). Nine out of ten patients reported to either never (67%) or rarely (25%) change their medical regimen. However, 8% reported to change it once in a while or often. Compliance behavior was mostly rated as very easy (36%) or easy (45%) to implement. Nevertheless, 19% perceived it to be partly difficult or difficult to follow medical regimen. Symptoms of AjD (β = 0.31, p < 0.001) were associated with more difficulties to comply. Higher compliance behavior in turn was associated with stem cell transplantation (SCT) treatment (β = -0.21, p < 0.001) and lower education (β = -0.19, p = 0.002).

Conclusion

Although most patients indicated that they comply with medical regimen, a considerable subgroup of patients indicated subjectively perceived difficulties and thus seem to require additional support in implementing medical instructions possibly through improved medical communication and patient health literacy or shared decision-making.

Severe mental illness and the risk of breast cancer: A two-sample, two-step multivariable Mendelian randomization study

BACKGROUND

Based on epidemiological reports, severe mental illness (SMI) and breast cancer (BC) risk are linked positively. However, it is susceptible to clinical confounding factors, such as smoking, alcohol consumption, etc. Here, we performed a two-sample, two-step multivariable Mendelian randomization (MR) research to explore how the SMI etiologically influences BC risk and to quantify mediating effects of known modifiable risk factors.

METHODS

Data concerning the single nucleotide polymorphism (SNP)-associated with schizophrenia, bipolar disorder (BD), major depressive disorder (MDD), and BC were obtained from two large consortia: the Breast Cancer Association Consortium (BCAC) and the Psychiatric Genomics Consortium (PGC). Then, the correlations of the previous SMI with the BC prevalence and the potential impact of mediators were explored through the two-sample and two-step MR analyses.

RESULTS

In two-sample MR, schizophrenia increased BC incidence (odds ratio (OR) 1.06, 95% confidence interval (CI) 1.02-1.10, P = 0.001). In subgroup analysis, schizophrenia increased ER+ BC (OR 1.06, 95% CI 1.03-1.10, P = 0.0009) and ER-BC (OR 1.06, 95% CI 1.01-1.11, P = 0.0123) incidences. Neither MDD nor BD elevated the BC risk. In two-step MR, smoking explained 11.29% of the schizophrenia-all BC risk association.

CONCLUSIONS

Our study indicates that schizophrenia increases susceptibility to breast cancer, with smoking playing a certain mediating role. Therefore, BC screening and smoking should be incorporated into the health management of individuals with schizophrenia.

Symptoms of posttraumatic stress disorder and adjustment disorder in hematological cancer patients with different treatment regimes

BACKGROUND

Symptoms of posttraumatic stress disorder (PTSD) and adjustment disorder (AjD) are common in hematological cancer patients as they face severe stressors during their serious disease and often intensive treatment, such as stem cell transplantation (SCT). Aims of the present study were to provide frequency and risk factors for PTSD and AjD based on updated diagnostic criteria that are lacking to date.

MATERIAL AND METHODS

In a cross-sectional study, hematological cancer patients were assessed for stressor-related symptoms via validated self-report questionnaires based on updated criteria for PTSD (PCL-5) and AjD (ADMN-20). Frequency and symptom severity were estimated among the total sample and SCT subgroups (allogeneic, autologous, no SCT). SCT subgroups were compared using Chi-squared-tests and ANOVAs. Linear regression models investigated sociodemographic and medical factors associated with symptomatology.

RESULTS

In total, 291 patients were included (response rate: 58%). 26 (9.3%), 66 (23.7%) and 40 (14.2%) patients met criteria for cancer-related PTSD, subthreshold PTSD and AjD, respectively. Symptom severity and frequency of criteria-based PTSD and AjD did not differ between SCT subgroups (all p > 0.05). Factors associated with elevated symptomatology were younger age (PTSD: p < 0.001; AjD: p = 0.02), physical comorbidity (PTSD: p < 0.001; AjD: p < 0.001) and active disease (PTSD: p = 0.12; AjD: p = 0.03).

CONCLUSION

Based on new criteria, a considerable part of hematological cancer patients reports PTSD and AjD symptoms. Younger patients and patients with physical symptom burden might be particularly at risk and need to be monitored closely to enable effective treatment at an early stage.

Investigation of Factors Affecting Adherence to Adjuvant Hormone Therapy in Early-Stage Breast Cancer Patients: A Comprehensive Systematic Review

PURPOSE

Adherence and persistence to adjuvant hormone therapy (AHT) are seldom maintained among early-stage hormone receptor-positive breast cancer (BC) survivors, despite the significant clinical benefits of long-term AHT. As the factors influencing adherence to AHT remain unclear, this study aimed to comprehensively identify such factors and classify them into specific dimensions.

METHODS

PubMed, Cochrane Library, Embase, PsycINFO, and CINAHL were searched for qualified articles. The search mainly focused on three components: early-stage (0-III) BC, oral AHT administration, and adherence to AHT, with keywords derived from MeSH and entry terms. The factors identified were then classified into six categories based on a modified WHO multidimensional model.

RESULTS

Overall, 146 studies were included; the median sample size was 651 (range, 31-40,009), and the mean age of the population was 61.5 years (standard deviation, 8.3 years). Patient- and therapy-related factors were the most frequently investigated factors. Necessity/concern beliefs and self-efficacy among patient-related factors were consistently related to better adherence than depression. Although drug side effects and medication use cannot be modified easily, a refined prescription strategy for the initiation and switching of AHT is likely to increase adherence levels.

CONCLUSION

An effective psychological program that encourages positive views and beliefs about medication and management strategies for each therapy may be necessary to improve adherence to AHT. Social support and a sense of belonging can be enhanced through community participation and social media for better adherence to AHT. Patient-centered communication and appropriate recommendations by physicians may be attributable to better adherence outcomes. Findings from systematically organized factors that influence adherence to AHT may contribute to the establishment of intervention strategies to benefit patients with early-stage BC to achieve optimal health.

Predictors of quality of life and mental health in breast cancer survivors in Northern Iran

BACKGROUND AND PURPOSE

The global incidence of breast cancer is the highest among all cancers and is the primary reason for cancer-related fatalities. Our study aimed to assess the predictors of quality of life (QOL) and mental health in breast cancer survivors in Northern Iran.

METHODS

This cross-sectional study was done on 96 female breast cancer survivors between the ages of 20 and 65 and was based on convenience samples. We gathered information through demographic and fertility data, a QOL survey, and the Hospital Anxiety and Depression Scale (HADS). A significance level of P < 0.05 was set for the analysis.

RESULTS

In this study, results showed that 11.5% of women had the optimal quality of life, 31.3% favorable quality of life, and 57.3% undesirable quality of life. The average HADS score was 20.14 ± 3.07, with anxiety scores of 10.21 ± 2.31 and depression scores of 9.93 ± 1.64. On multiple linear regression, marital relationship and the number of children were predictors of quality of life (β=-17.624, p = 0.023 and β=-7.427, p = 0.016, respectively), as well as the husband's education and having no history of other cancers in the woman, were the most important predictors of HADS (β = 0.763, p = 0.039 and β=-0.528, p = 0.016, respectively).

CONCLUSION

It is crucial to provide exceptional care to breast cancer patients during treatment and post-recovery. Emotional and psychological support is a fundamental requirement for their well-being.

The Impact of Psychiatric Diagnoses on Patient-reported Satisfaction and Quality of Life in Postmastectomy Breast Reconstruction

OBJECTIVE

The purpose of this study was to determine the prevalence of psychiatric diagnoses among a sample of breast reconstruction patients and measure the association between these diagnoses and reconstruction-related, patient-reported outcomes.

BACKGROUND

The impact of psychiatric disorders in conjunction with breast cancer diagnosis, treatment, and reconstruction have the potential to cause significant patient distress but remains not well understood.

METHODS

A retrospective review of postmastectomy breast reconstruction patients from 2007 to 2018 at Memorial Sloan Kettering Cancer Center was conducted. Patient demographics, comorbidities, cancer characteristics, psychiatric diagnoses, and BREAST-Q Reconstruction Module scores (measuring satisfaction with breast, well-being of the chest, psychosocial, and sexual well-being) at postoperative years 1 to 3 were examined. Mixed-effects models and cross-sectional linear regressions were conducted to measure the effect of psychiatric diagnostic class type and number on scores.

RESULTS

Of 7414 total patients, 50.1% had at least 1 psychiatric diagnosis. Patients with any psychiatric diagnoses before reconstruction had significantly lower BREAST-Q scores for all domains at all time points. Anxiety (50%) and depression (27.6%) disorders were the most prevalent and had the greatest impact on BREAST-Q scores. Patients with a greater number of psychiatric diagnostic classes had significantly worse patient-reported outcomes compared with patients with no psychiatric diagnosis. Psychosocial (β: -7.29; 95% confidence interval: -8.67, -5.91), and sexual well-being (β: -7.99; 95% confidence interval: -9.57, -6.40) were most sensitive to the impact of psychiatric diagnoses.

CONCLUSIONS

Mental health status is associated with psychosocial and sexual well-being after breast reconstruction surgery as measured with the BREAST-Q. Future research will need to determine what interventions (eg, screening, early referral) can help improve outcomes for breast cancer patients with psychiatric disorders undergoing breast reconstruction.

Telehealth-Based Music Therapy Versus Cognitive Behavioral Therapy for Anxiety in Cancer Survivors: Rationale and Protocol for a Comparative Effectiveness Trial

BACKGROUND

Cancer survivors represent one of the fastest growing populations in the United States. Unfortunately, nearly 1 in 3 survivors experience anxiety symptoms as a long-term consequence of cancer and its treatment. Characterized by restlessness, muscle tension, and worry, anxiety worsens the quality of life; impairs daily functioning; and is associated with poor sleep, depressed mood, and fatigue. Although pharmacological treatment options are available, polypharmacy has become a growing concern for cancer survivors. Music therapy (MT) and cognitive behavioral therapy (CBT) are evidence-based, nonpharmacological treatments that have demonstrated effectiveness in treating anxiety symptoms in cancer populations and can be adapted for remote delivery to increase access to mental health treatments. However, the comparative effectiveness of these 2 interventions delivered via telehealth is unknown.

OBJECTIVE

The aims of the Music Therapy Versus Cognitive Behavioral Therapy for Cancer-related Anxiety (MELODY) study are to determine the comparative effectiveness of telehealth-based MT versus telehealth-based CBT for anxiety and comorbid symptoms in cancer survivors and to identify patient-level factors associated with greater anxiety symptom reduction for MT and CBT.

METHODS

The MELODY study is a 2-arm, parallel-group randomized clinical trial that aims to compare the effectiveness of MT versus CBT for anxiety and comorbid symptoms. The trial will enroll 300 English- or Spanish-speaking survivors of any cancer type or stage who have experienced anxiety symptoms for at least 1 month. Participants will receive 7 weekly sessions of MT or CBT delivered remotely via Zoom (Zoom Video Communications, Inc) over 7 weeks. Validated instruments to assess anxiety (primary outcome), comorbid symptoms (fatigue, depression, insomnia, pain, and cognitive dysfunction), and health-related quality of life will be administered at baseline and at weeks 4, 8 (end of treatment), 16, and 26. Semistructured interviews will be conducted at week 8 with a subsample of 60 participants (30 per treatment arm) to understand individual experiences with the treatment sessions and their impact.

RESULTS

The first study participant was enrolled in February 2022. As of January 2023, 151 participants have been enrolled. The trial is expected to be completed by September 2024.

CONCLUSIONS

This study is the first and largest randomized clinical trial to compare the short- and long-term effectiveness of remotely delivered MT and CBT for anxiety in cancer survivors. Limitations include the lack of usual care or placebo control groups and the lack of formal diagnostic assessments for psychiatric disorders among trial participants. The study findings will help guide treatment decisions for 2 evidence-based, scalable, and accessible interventions to promote mental well-being during cancer survivorship.

Impact of pre-existing mental health disorders on the receipt of guideline recommended cancer treatments: A systematic review

OBJECTIVE

Disparities in cancer outcomes for individuals with pre-existing mental health disorders have already been identified, particularly for cancer screening and mortality. We aimed to systematically review the influence on the time from cancer diagnosis to cancer treatment, treatment adherence, and differences in receipt of guideline recommended cancer treatment.

METHODS

We included international studies published in English from 1 January 1995 to 23 May 2022 by searching MEDLINE, Embase, and APA PsycInfo.

RESULTS

This review identified 29 studies with 27 being published in the past decade. Most studies focused on breast, non-small cell lung and colorectal cancer and were of high or medium quality as assessed by the Newcastle Ottawa Scale. All studies were from high-income countries, and mostly included patients enrolled in national health insurance systems. Five assessed the impact on treatment delay or adherence, and 25 focused on the receipt of guideline recommended treatment. 20/25 studies demonstrated evidence that patients with pre-existing mental health disorders were less likely to receive guideline recommended therapies such as surgery or radiotherapy. In addition, there was a greater likelihood of receiving less intensive or modified treatment including systemic therapy.

CONCLUSIONS

Across different cancer types and treatment modalities there is evidence of a clear disparity in the receipt of guideline recommended cancer treatment for patients with pre-existing mental health disorders. The effect of pre-existing mental health disorders on treatment delay or adherence is under-researched. Future research needs to include low- and middle-income countries as well as qualitative investigations to understand the reasons for disparities in cancer treatment.

Preventing metastatic recurrence in low-risk ER/PR + breast cancer patients-a retrospective clinical study exploring the evolving challenge of persistence with adjuvant endocrine therapy

PURPOSE

In the genomic era, more women with low-risk breast cancer will forego chemotherapy and rely on adjuvant endocrine therapy (AET) to prevent metastatic recurrence. However, some of these patients will unfortunately relapse. We sought to understand this outcome. Preliminary work suggested that early discontinuation of AET, also known as non-persistence, may play an important role. A retrospective analysis exploring factors related to our breast cancer patients' non-persistence with AET was performed.

METHODS

Women who underwent Oncotype-DX® testing between 2011 and 2014 with minimum 5 years follow-up were included. 'Low risk' was defined as Oncotype score < 26. Outcomes of recurrence and persistence were determined by chart review. Patient, tumor and treatment factors were collected, and persistent versus non-persistent groups compared using multivariable ANOVA and Fisher Chi square exact test.

RESULTS

We identified six cases of distant recurrence among low-risk patients with a median follow-up of 7.7 years. Among them, five of six patients (83%) were non-persistent with AET. The non-persistence rate in our cohort regardless of recurrence was 57/228 (25%). Non-persistent patients reported more severe side effects compared with persistent patients (p = 0.002) and were more likely to be offered a switch in endocrine therapy, rather than symptom-relief (p = 0.006). In contrast, persistent patients were 10.3 times more likely to have been offered symptom-alleviating medications compared with non-persistent patients (p < 0.001). A subset analysis revealed that patients who persisted with therapy had a higher Oncotype-DX® score than patients who discontinued early (p = 0.028).

CONCLUSION

Metastatic recurrence in low-risk breast cancer patients may be primarily due to non-persistence with endocrine therapy. Further work is needed to optimize care for patients who struggle with side effects. To our knowledge, these are the first published data suggesting that Oncotype-DX® score may influence persistence with AET.

Factors associated with initiation and continuation of endocrine therapy in women with hormone receptor-positive breast cancer

Background

Despite benefits of endocrine therapy (ET) for patients with hormone-receptor (HR)-positive breast cancer, many patients do not initiate or discontinue ET against recommendations.

Methods

We identified variables associated with ET initiation and continuation, analyzing pooled data from two longitudinal studies at a National Cancer Institute comprehensive cancer center in St. Louis, Missouri. The sample included 533 women with newly diagnosed, non-metastatic, HR-positive breast cancer who completed interviews at enrollment and 6, 12, and 24 months after definitive surgical treatment. Logistic regression models estimated the adjusted odds ratio and 95% confidence interval (aOR [95% CI]) for each of self-reported ET initiation by the 12-month interview and continuation for ≥12 months by the 24-month interview in association with self-reported diabetes, elevated depressed mood, menopausal-symptom severity and obesity, adjusting for race, age, insurance status, chemotherapy, and radiation therapy.

Results

Overall, 81.4% (434/533) of patients initiated ET, and 86.5% (371/429) continued ET ≥12 months. Patients with diabetes had lower odds of initiating ET (0.50 [0.27-0.91]). Patients reporting greater menopausal-symptom severity had lower odds of continuing ET (0.72 [0.53-0.99]).

Conclusion

Efforts to increase ET initiation among patients with diabetes and better manage severe menopausal symptoms among ET users might promote ET continuation.

Colorectal cancer treatment in people with severe mental illness: a systematic review and meta-analysis

AIMS

People with severe mental illness (SMI) have a greater risk of dying from colorectal cancer (CRC), even though the incidence is lower or similar to that of the general population This pattern is unlikely to be solely explained by lifestyle factors, while the role of differences in cancer healthcare access or treatment is uncertain.

METHODS

We undertook a systematic review and meta-analysis on access to guideline-appropriate care following CRC diagnosis in people with SMI including the receipt of surgery, chemo- or radiotherapy. We searched for full-text articles indexed by PubMed, EMBASE, PsychInfo and CINAHL that compared CRC treatment in those with and without pre-existing SMI (schizophrenia, schizoaffective, bipolar and major affective disorders). Designs included cohort or population-based case-control designs.

RESULTS

There were ten studies (sample size = 3501-591 561). People with SMI had a reduced likelihood of surgery (RR = 0.90, 95% CI 0.92-0.97; p = 0.005; k = 4). Meta-analyses were not possible for the other outcomes but in results from individual studies, people with SMI were less likely to receive radiotherapy, chemotherapy or sphincter-sparing procedures. The disparity in care was greatest for those who had been psychiatric inpatients.

CONCLUSIONS

People with SMI, including both psychotic and affective disorders, receive less CRC care than the general population. This might contribute to higher case-fatality rates for an illness where the incidence is no higher than that of the general population. The reasons for this require further investigation, as does the extent to which differences in treatment access or quality contribute to excess CRC mortality in people with SMI.

Factors Influencing Adherence to Antipsychotic Medications in Women with Delusional Disorder: A Narrative Review

BACKGROUND

Adherence to medication regimens is of great importance in psychiatry because drugs sometimes need to be taken for long durations in order to maintain health and function.

OBJECTIVE

To review influences on adherence to antipsychotic medications, the treatment of choice for delusional disorder (DD), and to focus on adherence in women with DD.

METHOD

A non-systematic narrative review of papers published since 2000 using PubMed and Google Scholar and focusing on women with DD and medication adherence.

RESULTS

Several factors have been identified as exerting influence on adherence in women with persistent delusional symptoms who are treated with antipsychotics. Personality features, intensity of delusion, perception of adverse effects, and cognitive impairment are patient factors. Clinical time spent with the patient, clarity of communication and regular drug monitoring are responsibilities of the health provider. Factors that neither patient nor clinician can control are the social determinants of health such as poverty, easy access to healthcare, and cultural variables.

CONCLUSIONS

There has been little investigation into factors that influence adherence in the target population discussed here -e.g. women with DD. Preliminary results of this literature search indicate that solutions from outside the field of DD may apply to this population. Overall, a solid therapeutic alliance appears to be the best hedge against non-adherence.

Precancer and cancer-associated depression and anxiety among older adults with blood cancers in the United States

For patients with blood cancers, comorbid mental health disorders at diagnosis likely affect the entire disease trajectory, as they can interfere with disease information processing, lead to poor coping, and even cause delays in care. We aimed to characterize the prevalence of depression and anxiety in patients with blood cancers. Using the Surveillance, Epidemiology, and End Results-Medicare database, we identified patients ≥67 years old diagnosed with lymphoma, myeloma, leukemia, or myelodysplastic syndromes between 2000 and 2015. We determined the prevalence of precancer depression and anxiety and cancer-associated (CA) depression and anxiety using claims data. We identified factors associated with CA-depression and CA-anxiety in multivariate analyses. Among 75 691 patients, 18.6% had at least 1 diagnosis of depression or anxiety. Of the total cohort, 13.7% had precancer depression and/or precancer anxiety, while 4.9% had CA-depression or CA-anxiety. Compared with patients without precancer anxiety, those with precancer anxiety were more likely to have subsequent claims for CA-depression (odds ratio [OR] 2.98; 95% CI 2.61-3.41). Other factors associated with a higher risk of CA- depression included female sex, nonmarried status, higher comorbidity, and myeloma diagnosis. Patients with precancer depression were significantly more likely to have subsequent claims for CA-anxiety compared with patients without precancer depression (OR 3.01; 95% CI 2.63-3.44). Female sex and myeloma diagnosis were also associated with CA-anxiety. In this large cohort of older patients with newly diagnosed blood cancers, almost 1 in 5 suffered from depression or anxiety, highlighting a critical need for systematic mental health screening and management for this population.

Gynecological Health Concerns in Women with Schizophrenia and Related Disorders: A Narrative Review of Recent Studies

Sex and age are important factors influencing physical and mental health in schizophrenia. Our goal was to review the recent literature for associations between gynecological conditions and psychotic illness and to propose integrated strategies for their management in order to improve overall health outcomes in women. We addressed the following questions: What are the prevalence and risk factors of gynecological disorders in women with schizophrenia or delusional disorder (DD)? What are the rates of uptake of gynecological cancer screening and mortality in this population? What role does menopause play? We found an increased incidence of breast cancer in women with schizophrenia. Other gynecological comorbidities were less frequent, but the field has been understudied. Low rates of breast and cervical cancer screening characterize women with schizophrenia. Menopause, because of endocrine changes, aging effects, and resultant comorbidity is associated with high rates of aggressive breast cancer in this population. Uterine and ovarian cancers have been less investigated. Psychosocial determinants of health play an important role in cancer survival. The findings lead to the recommendation that primary care, psychiatry, gynecology, oncology, and endocrinology collaborate in early case finding, in research into etiological links, and in improvement of prevention and treatment.

Current Status and Problems of Breast Cancer Treatment with Schizophrenia

BACKGROUND

Schizophrenia is a devastating mental disease that affects approximately 1% of the world's population. Breast cancer is the second most common type of cancer in the world that causes death in women. It is often unclear whether patients with schizophrenia receive recommended cancer treatment that met the guideline. This study characterized breast cancer treatment disruptions in schizophrenia patients and sought to identify and resolve correctable predictors of those disruptions.

MATERIALS AND METHODS

A retrospective cohort study was conducted on 55 primary breast cancer patients diagnosed with schizophrenia and treated for breast cancer. We evaluated the characteristics of the breast cancer patients with schizophrenia compared to those of 610 breast cancer patients without schizophrenia.

RESULTS

Compared to the control group, the schizophrenia group had significantly advanced T and N factors and disease stage. Significantly fewer patients in the schizophrenia group than in the control group received chemotherapy (P < .0001) or recommended cancer treatment (P = .0004). Within the schizophrenia group, the patients in need of ADL support were significantly less likely to receive recommended cancer treatment.

CONCLUSION

Patients with schizophrenia are often diagnosed with breast cancer in advanced stages. In addition, patients with schizophrenia with reduced ADL are less likely to receive chemotherapy or recommended cancer treatment. It is highly recommended that patients with schizophrenia undergo breast cancer screening so that they can be diagnosed early and treated adequately.

Drawing Test Form for Depression: The Development of Drawing Tests for Predicting Depression Among Breast Cancer Patients

OBJECTIVE

The aim of this study is to develop a drawing test form and it's scoring system for measuring depressive symptoms of breast cancer patients.

METHODS

We enrolled 95 breast cancer patients in this study which was conducted from September 2016 to May 2018. First, we observed items of the Diagnostic Drawing Series (DDS) which were significantly different between patients with and without depression, and also we reviewed previous studies on the drawing style of Korean women with depression. Second, we developed the Drawing Test Form for Depression (DTF-D) by composition of those drawing styles observed significant items in previous literatures and formative elements of DDS which was significantly different between depressed and non-depressed group. The receiver operating characteristic (ROC) curve analysis was used to define the appropriate score of the DTF-D in accordance with the depression measured with Patient Health Questionnaire-9 (PHQ-9) score >9.

RESULTS

We developed the DTF-D by compositing 8 items including Harmony, Tilt, Symbol, Space utilization, Surrounded, Description, Pen pressure, and Quality of line. The ROC analysis revealed the optimal cut-off score of 7 points of DTF-D in accordance with the clinical depression (PHQ-9 score >9) with the area under the receiver operating characteristics curve showed good discrimination (0.82), sensitivity (0.85), and specificity (0.64).

CONCLUSION

The DTF-D is expected to serve as an evaluative projective drawing test from for identifying depression in breast cancer patients.

Association of Modifiable Risk Factors With Early Discontinuation of Adjuvant Endocrine Therapy: A Post Hoc Analysis of a Randomized Clinical Trial

IMPORTANCE

Early discontinuation of adjuvant endocrine therapy (ET) is problematic among breast cancer survivors, with previous studies suggesting that up to 50% of women do not adhere to the recommended full 5 years of ET treatment.

OBJECTIVE

To identify the association between early discontinuation of ET in the Trial Assigning Individualized Options for Treatment (TAILORx) and modifiable risk factors, polypharmacy, and types of additional medications such as antidepressants and opioids.

DESIGN, SETTING, AND PARTICIPANTS

This post hoc analysis includes a subgroup of 954 patients with breast cancer in TAILORx, a randomized clinical trial conducted from April 7, 2006, to October 6, 2010. All participants received a diagnosis of hormone receptor-positive, ERBB2-negative, axillary node-negative breast cancer and started ET within a year of study entry. Analyses were conducted in the intent-to-treat population. Statistical analysis took place from January 15, 2020, to April 6, 2021.

MAIN OUTCOMES AND MEASURES

Participants completed measures on cancer-related health-related quality of life including physical well-being and social well-being prior to initiating ET. Early discontinuation of ET was defined as discontinuation less than 4 years from initiation for reasons other than death or recurrence. Kaplan-Meier estimates were used to calculate discontinuation, and Cox proportional hazards regression joint prediction models were used to analyze the association between rates of adherence to ET with patient-level factors.

RESULTS

A total of 954 women (mean [SD] age, 56.6 [8.9] years) were included in this analysis. In a joint model, receipt of chemoendocrine therapy (vs receipt of ET only; hazard ratio [HR], 0.57; 95% CI, 0.35-0.92; P = .02) and age older than 40 years (vs ≤40 years; HR for 41-50 years, 0.39; 95% CI, 0.18-0.85; P = .02; HR for 51-60 years, 0.28; 95% CI, 0.13-0.60; P = .001; HR for 61-70 years, 0.40; 95% CI, 0.18-0.86; P = .02; and HR for >70 years, 0.23; 95% CI, 0.07-0.77; P = .02) were associated with a lower probability of early discontinuation of ET. Adjusted for these factors, a history of depression compared with no history of depression (HR, 1.82; 95% CI, 1.19-2.77; P = .005), worse physical well-being compared with better physical well-being (HR, 2.12; 95% CI, 1.30-3.45; P = .002), and worse social well-being compared with better social well-being (HR, 1.94; 95% CI, 1.20-3.13; P = .006) were individually and significantly associated with a higher probability of early discontinuation of ET. Only antidepressant use at study baseline was associated with early discontinuation (HR, 1.87; 95% CI, 1.23-2.84; P = .003).

CONCLUSIONS AND RELEVANCE

In this post hoc analysis of a randomized clinical trial, baseline patient-reported health-related quality of life components, such as poor social well-being, poor physical well-being, and comorbid depression, were significant risk factors for early discontinuation of endocrine therapies. These results support systematic screening for patient-reported outcomes and depressive symptoms to identify women at risk for discontinuation of ET.

Association of Depression with In-Patient and Post-Discharge Disposition and Expenditures Among Medicare Beneficiaries Undergoing Resection for Cancer

BACKGROUND

The impact of depression on utilization of post-discharge care and overall episode of care expenditures remains poorly defined. We sought to define the impact of depression on postoperative outcomes, including discharge disposition, as well as overall expenditures associated with the global episode of surgical care.

METHOD

The Medicare 100% Standard Analytic Files were used to identify patients undergoing resection for esophageal, colon, rectal, pancreatic, and liver cancer between 2013 and 2017. The impact of depression on inpatient outcomes, as well as home health care and skilled nursing facilities utilization and expenditures, was analyzed.

RESULTS

Among 113,263 patients, 14,618 (12.9%) individuals had depression. Patients with depression were more likely to experience postoperative complications (odds ratio [OR] 1.36, 95% confidence interval [CI] 1.31-1.42), extended length of stay (LOS) (OR 1.41, 95% CI 1.36-1.47), readmission within 90 days (OR 1.20, 95% CI 1.14-1.25), as well as 90-day mortality (OR 1.35, 95% CI 1.27-1.42) (all p < 0.05). In turn, the proportion of patients who achieved a textbook outcome following cancer surgery was lower among patients with depression (no depression: 53.3% vs. depression: 45.3%; OR 0.70, 95% CI 0.68-0.73). Patients with a preexisting diagnosis of depression had higher odds of additional post-discharge expenditures compared with individuals without a diagnosis of depression (OR 1.42; 95% CI 1.35-1.50); patients with a preexisting diagnosis of depression ($10,500, IQR $3,200-$22,500) had higher median post-discharge expenditures versus patients without depression ($6600, IQR $2100-$17,400) (p < 0.001). On multivariable analysis, after controlling for other factors, depression remained associated with a 19.0% (95% confidence interval [CI] 15.7-22.3%) increase in post-discharge expenditures.

CONCLUSIONS

Patients with depression undergoing resection for cancer had worse in-patient outcomes and were less likely to achieve a TO. Patients with depression were more likely to require post-discharge care and had higher post-discharge expenditures.

Association of pre-existing mental illness with all-cause and cancer-specific mortality among Medicare beneficiaries with pancreatic cancer

BACKGROUND

Among patients with pancreatic cancer, the association of pre-existing mental illness with long-term outcomes remains unknown.

METHODS

Individuals diagnosed with pancreatic adenocarcinoma were identified in the SEER-Medicare database. Patients were classified as having mental illness if an ICD9/10CM code for anxiety, depression, bipolar disorder, schizophrenia or other psychotic disorder was recorded.

RESULTS

Among the 54,234 Medicare beneficiaries with pancreatic cancer, roughly 1 in 12 (n = 4793, 8.83%) individuals had a diagnosis of a mental illness. The majority (n = 4029, 84.1%) had anxiety or depression, while 16% (n = 764) had bipolar/schizophrenic disorders. On multivariable analysis, among patients with early stage cancer, individuals with pre-existing anxiety/depression and bipolar/schizophrenic disorders had 22% (OR 0.78, 95% CI 0.69-0.86) and 46% (OR 0.54, 95% CI 0.42-0.70) reduced odds, respectively, to undergo cancer-directed surgery. Furthermore, patients with a pre-existing history of bipolar/schizophrenic disorders had a 20% (HR 1.20, 95% CI 1.21-1.40) higher risk of all-cause mortality and 27% (HR 1.27, 95% CI 1.17-1.37) higher risk of pancreatic cancer-specific mortality compared to individuals without a history of mental illness.

CONCLUSION

One in twelve patients with pancreatic cancer had a pre-existing mental illness. Individuals with mental illness were more likely to have worse overall and cancer-specific long-term outcomes.

Impact of mental illness on end-of-life emergency department use in elderly patients with gastrointestinal malignancies

Background

Elderly patients with gastrointestinal cancer and mental illness have significant comorbidities that can impact the quality of their care. We investigated the relationship between mental illness and frequent emergency department (ED) use in the last month of life, an indicator for poor end‐of‐life care quality, among elderly patients with gastrointestinal cancers.

Methods

We used SEER‐Medicare data to identify decedents with gastrointestinal cancers who were diagnosed between 2004 and 2013 and were at least 66 years old at time of diagnosis (median age: 80 years, range: 66–117 years). We evaluated the association between having a diagnosis of depression, bipolar disorders, psychotic disorders, anxiety, dementia, and/or substance use disorders and ED use in the last 30 days of life using logistic regression models.

Results

Of 160,367 patients included, 54,661 (34.1%) had a mental illness diagnosis between one year prior to cancer diagnosis and death. Patients with mental illness were more likely to have > 1 ED visit in the last 30 days of life (15.6% vs. 13.3%, p < 0.01). ED use was highest among patients with substance use (17.7%), bipolar (16.5%), and anxiety disorders (16.4%). Patients with mental illness who were male, younger, non‐white, residing in lower income areas, and with higher comorbidity were more likely to have multiple end‐of‐life ED visits. Patients who received outpatient treatment from a mental health professional were less likely to have multiple end‐of‐life ED visits (adjusted odds ratio 0.82, 95% confidence interval 0.78–0.87).

Conclusions

In elderly patients with gastrointestinal cancers, mental illness is associated with having multiple end‐of‐life ED visits. Increasing access to mental health services may improve quality of end‐of‐life care in this vulnerable population.

Exploring the lengthiest ambulatory breast surgery clinic appointments: is the patient the problem?

Background

Prolonged outpatient clinic appointments can disrupt schedules, impacting patients and providers. We sought to define features of the longest ambulatory appointments in a breast surgery clinic, and to ascertain whether patients attending these appointments consistently have protracted appointments.

Methods

A single-institution retrospective cohort study was conducted of breast surgery clinic patients, January 2017 to May 2019, and the longest 1% of appointments identified using a real-time patient tracking system. A primary chart review was performed, and data abstracted. Other appointments attended by these patients were identified, and the ratio of appointments >75th percentile duration (protracted appointments) to the total appointments during the study period was calculated, enabling comparison for patients with consistently protracted (ratio >50%) vs. sporadically protracted appointments (≤50%). Descriptive analysis was performed, and results reported as medians with inter-quartile ranges.

Results

A total of 15,265 clinic appointments were identified, and the longest 148 (exceeding 244 minutes) analyzed. Median appointment length was 264 minutes (inter-quartile range: 253-290). 70% were new patient appointments, and 54% of patients underwent a test/investigation that day. A minority were obese (39%), smokers (41%), diagnosed with a psychiatric comorbidity (34%), had a genetic cancer syndrome (22%), or received unexpected news at their appointment (16%). Of 118 patients with multiple appointments, 26% had consistently protracted appointments and 74% sporadically protracted appointments.

Conclusions

The lengthiest appointments are usually newly diagnosed cancer patients. Only a minority of patients have consistently protracted appointments, implying that a patient's previously prolonged appointment may not predict future long appointments.

Association between preexisting mental illnesses and mortality among medicaid-insured women diagnosed with breast cancer

BACKGROUND

We investigated the impact of preexisting mental illnesses on all-cause and cause-specific mortality among Medicaid-insured women diagnosed with breast cancer.

METHODS

Data from the New York State Cancer Registry for 10,444 women diagnosed with breast cancer from 2004 to 2016 and aged <65 years at diagnosis were linked with Medicaid claims. Women were categorized as having depression or a severe mental illness (SMI) if they had at least three relevant diagnosis claims with at least one claim within three years prior to breast cancer diagnosis. SMI included schizophrenia, bipolar disorder, and other psychotic disorders. Estimated menopausal status was determined by age (premenopausal age <50; postmenopausal age ≥50). Hazard ratios (HR) and 95% confidence intervals (95%CI) were calculated with Cox proportional hazards regression, adjusting for potential confounders.

RESULTS

Preexisting SMI was associated with greater all-cause (HR = 1.36; 95%CI 1.18, 1.57) and cancer-specific (HR = 1.21; 95%CI 1.03, 1.44) mortality compared to those with no mental illnesses. No association was observed between preexisting depression and mortality. Among racial/ethnic subgroups, the association between SMI and all-cause mortality was observed among non-Hispanic white (HR = 1.47; 95%CI 1.19, 1.83) and non-Hispanic Asian/Pacific Islander (HR = 2.59; 95% 1.15, 5.87) women. Additionally, mortality hazards were greatest among women with preexisting SMI that were postmenopausal (HR = 1.49; 95%CI 1.25, 1.78), obese (HR = 1.58; 95%CI 1.26, 1.98), and had documented tobacco use (HR = 1.42; 95%CI 1.13, 1.78).

CONCLUSION

Women with preexisting SMI prior to breast cancer diagnosis have an elevated mortality hazard and should be monitored and treated by a coordinated cross-functional clinical team.

Post-surgery anxiety and depression in prostate cancer patients: prevalence, longitudinal progression, and their correlations with survival profiles during a 3-year follow-up

Background

Anxiety and depression are more frequent in cancer patients than general population and may be correlated with cancer prognosis; however, their value in prostate cancer patients is largely unknown. We aimed to evaluate prevalence of anxiety and depression in prostate cancer survivors post the surgeries, and their correlations with patients’ disease-free survival (DFS) and overall survival (OS).

Methods

A hundred and ninety-four patients with prostate cancer who underwent radical prostatectomy were enrolled. After discharged from hospital, patients were assessed for post-surgery anxiety and depression every 3 months using Zung Self-rating Anxiety/Depression Scale (SAS/SDS) for a total of 36 months. In addition, disease conditions, DFS, and OS were also documented.

Results

SAS score (P < 0.001), anxiety rate (P = 0.004), SDS score (P < 0.001), and depression rate (P < 0.001) gradually elevated from baseline to month 36 in prostate cancer patients. Anxiety at baseline (P = 0.009) and anxiety at 3 years (P = 0.017) were correlated with worse DFS, and anxiety at baseline (P = 0.009) was also correlated with shorter OS in prostate cancer patients. Furthermore, depression at baseline (P = 0.005) and depression at 2 years (P = 0.008) were associated with unfavorable DFS, and depression at baseline (P = 0.001), 1 year (P = 0.025), and 2 years (P = 0.008) were associated with worse OS in prostate cancer patients. Moreover, multivariate Cox’s proportional hazards regression analysis elucidated that depression at baseline (P = 0.027) was an independent predictive factor for shorter DFS in prostate cancer patients.

Conclusion

Anxiety and depression both gradually deteriorate, and they correlate with unfavorable survival profile in prostate cancer patients after radical prostatectomy.

Breast cancer endocrine therapy adherence in health professional shortage areas: Unique effects on patients with mental illness

OBJECTIVE

Evaluate whether breast cancer endocrine therapy adherence is affected by access to primary and mental health care, particularly among at-risk patients with mental illness.

METHODS

The study included 21,892 SEER-Medicare women aged 68 or older with stage I-IV ER+ breast cancer, 2007 to 2013. Patient home counties during breast cancer diagnosis, if evaluated for HPSA care shortage status, were categorized as least, moderate, or highest shortage; unevaluated counties (no known shortage) were a fourth category. Endocrine therapy initiation and discontinuation were analyzed with Cox regression, and daily adherence with longitudinal linear regression.

RESULTS

After multivariate adjustment, patients in high primary care shortage counties were less likely to initiate endocrine therapy, reference least shortage [HR 0.92 (95% CI 0.86-0.97)]. Unevaluated counties had more oncologists per capita, fewer residents below the federal poverty level, and higher incomes. Mental health shortages were not associated with outcomes, however subgroups living in unevaluated counties were less likely to discontinue: patients with bipolar and psychotic disorders [discontinuation HR 0.35 (95% CI 0.17-0.73)], substance use [HR 0.48 (95% CI 0.24-0.95)], anxiety disorders [HR 0.56 (95% CI 0.35-0.90)].

CONCLUSIONS

Poor primary care access was associated with a lower likelihood of initiating endocrine therapy but living in counties without established mental health shortages may reduce the harmful association between mental illness and incomplete treatment receipt. Patients with mental illness may be more equipped to complete cancer treatment if given better mental health care access, suggesting a need for care coordination between primary and mental health care.

The Patient's Voice: Adherence, Symptoms, and Distress Related to Adjuvant Endocrine Therapy After Breast Cancer

BACKGROUND

While adjuvant endocrine therapy (AET) for early-stage, hormone-sensitive breast cancer confers a 40-50% reduction in recurrence risk, adherence to AET is suboptimal, and no efficacious interventions exist to improve adherence. A qualitative study was conducted to understand patient experiences on AET, motivators and barriers to adherence, side effects, and distress, with the goal of developing a patient-centered, evidence-based intervention.

METHOD

From November 2017 to November 2018, female patients with early-stage, hormone receptor-positive breast cancer taking AET were recruited. Patients with low and high medication adherence of varying ages, levels of distress, and years taking AET were purposefully enrolled. In-depth semi-structured interviews were conducted, audio recorded, and transcribed. Study staff created a thematic framework, and three independent researchers coded interviews using NVivo 11, achieving high inter-coder agreement (Kappa = .96).

RESULTS

Thirty interviews were conducted with patients who were, on average, 55.13 years old (SD = 12.37) and had been taking AET for a mean of 1.76 years (SD = 0.75). The sample was stratified by adherence level (low = 20; high = 10). Recurrent themes related to adherence included a commitment to AET to prevent recurrence despite distressing side effects, lack of strategies to cope with symptoms and distress, and desire for emotional support from others taking AET. Patients were highly accepting of a proposed psychosocial intervention to manage AET.

CONCLUSION

Patients are committed to taking AET to prevent breast cancer recurrence, but need and desire psychosocial support and skills training. Themes from this study are modifiable targets for a psychosocial, evidence-based intervention to promote adherence, coping with side effects, and distress management.

Post-diagnostic antipsychotic use and cancer mortality: a population based cohort study

BACKGROUND

Many antipsychotics elevate prolactin, a hormone implicated in breast cancer aetiology however no studies have investigated antipsychotic use in patients with breast cancer. This study investigated if antipsychotic use is associated with an increased risk of cancer-specific mortality among breast cancer patients.

METHODS

A cohort of 23,695 women newly diagnosed with a primary breast cancer between 1st January 1998 and 31st December 2012 was identified from the UK Clinical Practice Research Datalink linked to English cancer-registries and followed for until 30th September 2015. Time-dependent Cox proportional hazards models were used to calculate adjusted hazard ratios (HRs) and 95% confidence intervals (CIs) of breast cancer-specific mortality comparing use of antipsychotics with non-use, overall, and by prolactin elevating activitiy. Analyses were repeated restricting to patients with a history of severe mental illness to control for potential confounding by indication.

RESULTS

In total 848 patients were prescribed an antipsychotic and of which 162 died due to their breast cancer. Compared with non-use, antipsychotic use was associated with an increased risk of breast-cancer specific mortality (HR 2.25, 95%CI 1.90-2.67), but this did not follow a dose response relation. Restricting the cohort to patients with severe mental illness attenuated the association between antipsychotic use and breast cancer-specific mortality (HR 1.11, 95%CI 0.58-2.14).

CONCLUSIONS

In this population-based cohort of breast cancer patients, while the use of antipsychotics was associated with increased breast cancer-specific mortality, there was a lack of a dose response, and importantly null associations were observed in patients with severe mental illness, suggesting the observed association is likely a result of confounding by indication. This study provides an exemplar of confounding by indication, highlighting the importance of consideration of this important bias in studies of drug effects in cancer patients.

Receipt of psychological counseling and integrative medicine services among breast cancer survivors with anxiety

PURPOSE

To define the prevalence and risk factors of anxiety and examine rates and predictors of psychotherapy and integrative medicine service use in breast cancer survivors on aromatase inhibitors (AIs).

METHODS

Observational study of patients with histologically confirmed stage 0-III hormone receptor-positive breast cancer taking a third-generation AI at the time of enrollment. Patients completed self-report measures of anxiety and utilization of psychotherapy and integrative medicine services at a single time-point. We used multivariate logistic regression analyses to identify factors associated with anxiety and receipt of anxiety treatment services.

RESULTS

Among the 1085 participants, the majority were younger than 65 years of age (n = 673, 62.0%) and white (n = 899, 82.9%). Approximately one-third (30.8%) reported elevated anxiety (≥ 8 on the anxiety subscale of the Hospital Anxiety and Depression Scale). Of patients with elevated anxiety, only 24.6% reported receiving psychological counseling, 25.3% used integrative medicine services, and 39.8% received either type of treatment since their diagnosis. Patients with an education level of high school or less were less likely to receive psychological counseling (AOR, 0.43, 95% CI 0.19-0.95) and integrative medicine services (OR 0.30, 95% CI 0.12-0.72) than patients with higher levels of education.

CONCLUSIONS

Anxiety is common in breast cancer patients treated with AIs yet the majority of anxious patients do not receive evidence-based treatment, even when these treatments are available. Better systematic anxiety screening and treatment initiation are needed to reduce disparities in care by education level.

Effects of Previous Medication Regimen Factors and Bipolar and Psychotic Disorders on Breast Cancer Endocrine Therapy Adherence

BACKGROUND

Endocrine therapy adherence remains a barrier to optimal estrogen receptor-positive breast cancer outcomes. We theorized that experience navigating difficult medication regimen factors, such as route of administration complexity, might improve subsequent adherence after stressful cancer diagnoses but not for patients with bipolar and psychotic disorders at risk of poor access and nonadherence.

MATERIALS AND METHODS

We included 21,894 women aged ≥ 68 years at their first surgically treated stage I-IV estrogen receptor-positive breast cancer (2007-2013) from the Surveillance, Epidemiology, and End Results-Medicare data set, of whom 5.8% had bipolar or psychotic disorders. We required continuous fee-for-service Medicare (parts A and B) data for ≥ 36 months before and 18 months after the cancer diagnosis. The medication regimen factors in the part D claims for 4 months before included the number of all medications used, pharmacy visits, and administration complexity (medication regimen complexity index subscale). Cox regression analysis was used to model the time to initiation and discontinuation, with longitudinal linear regression for adherence to endocrine therapy.

RESULTS

Women with more frequent previous medication use and pharmacy visits were more likely to initiate, 4+ medications and 2+ visits versus no medication (hazard ratio [HR], 1.47; 95% confidence interval [CI], 1.33-1.63), to adhere (6.0%; 95% CI, 4.3-7.6), and to continuously use their endocrine therapy (discontinuation HR, 0.48; 95% CI, 0.39-0.59). Medication administration complexity had modest effects. Difficult medication regimens were more common for patients with bipolar and psychotic disorders but had no statistically significant effects.

CONCLUSIONS

Experience with frequent previous medication use and pharmacy visits might increase the likelihood of endocrine therapy use for most patients but not for those with bipolar and psychotic disorders.

Feasibility Study of a Novel Protease-Activated Fluorescent Imaging System for Real-Time, Intraoperative Detection of Residual Breast Cancer in Breast Conserving Surgery

BACKGROUND

Obtaining tumor-free margins is critical to prevent recurrence after lumpectomy for breast cancer. Unfortunately, current approaches leave positive margins that require second surgeries in 20-40% of patients. We assessed the LUM Imaging System for real-time, intraoperative detection of residual tumor.

METHODS

Breast lumpectomy cavity walls and excised specimens were assessed with the LUM Imaging System after 1 mg/kg intravenous LUM015, a protease-activatable fluorescent agent. Fluorescence at potential sites of residual tumor in lumpectomy cavity walls was evaluated intraoperatively with a sterile hand-held probe, with real-time predictive results displayed on a monitor intraoperatively, and later correlated with histopathology.

RESULTS

In vivo lumpectomy cavities and excised specimens were imaged after LUM015 injection in 45 women undergoing breast cancer surgery. Invasive ductal and lobular cancers and intraductal cancer (DCIS) were included. A total of 570 cavity margin surfaces in 40 patients were used for algorithm development. Image analysis and display took approximately 1 s per 2.6-cm-diameter circular margin surface. All breast cancer subtypes could be distinguished from adjacent normal tissue. For all imaged cavity surfaces, sensitivity for tumor detection was 84%. Among 8 patients with positive margins after standard surgery, sensitivity for residual tumor detection was 100%; 2 of 8 were spared second surgeries because additional tissue was excised at sites of LUM015 signal. Specificity was 73%, with some benign tissues showing elevated fluorescent signal.

CONCLUSIONS

The LUM015 agent and LUM Imaging System allow rapid identification of residual tumor in the lumpectomy cavity of breast cancer patients and may reduce rates of positive margins.

Relationship between preexisting mental disorders and prognosis of gynecologic cancers: A case-control study

AIM

Cancer treatment involves long-term therapy and follow-up, with mental disorders (MD) often affecting the treatment process. Hence, in this study, we retrospectively analyze cases involving gynecologic cancer with MD and clarify the relationship between psychosis and cancer prognosis.

METHODS

Patients with both gynecologic cancer and MD from January 2003 to August 2016 were recruited in this study. Cases were limited to those whose MD had been diagnosed before their cancer. Control patients without MD were also analyzed. Both cases and controls were adjusted for age, cancer type, and cancer stage.

RESULTS

A total of 54 patients with gynecologic cancer and MD, as well as 108 controls without MD, were included. The median age of the patients was 52 years. Details regarding cancer type were as follows: 11 ovarian cancers, 26 uterine corpus cancers and 17 cervical cancers. Among these, 25 schizophrenia cases, 15 depressive disorders, 4 bipolar disorders and 10 other MD were recorded. No significant differences in the 5-year survival rate were found between patients and controls. In advanced-stage cervical cancer, however, the prognosis was significantly poor given the low rate of initial treatment completion. Moreover, patients with advanced-stage cervical cancer had significantly lower chemotherapy completion rates compared to those with other gynecologic malignancies.

CONCLUSION

Mental disorders do not affect the prognosis of gynecologic cancers, except for advanced cervical cancer. Accordingly, improving the low rate of initial treatment completion seems to be a focal point for better prognosis in advanced cervical cancer.
