RESUMO

Palliative care improves patients' symptoms, quality of life and family satisfaction with caregiving, reduces hospital admissions and promotes alignment of medical care with the patient's needs and goals. This article proposes the utility of integrating three psychosocial theories into standard palliative care with implications for care planning, early palliative care and optimizing quality of life. First, Control Theory focuses on the complex juxtaposition of promoting agency/empowerment in patients and carers and coping with often highly uncertain outcomes. Second, Optimal Matching Theory accounts for the alignment of need and provision of care to potentiate the quality of life effects of supportive care in a complex social process involving health care providers, patients and carers. Third, Hope Theory represents a dynamic process, which is marked by variation in the qualities of hope as the patient and carer confront challenges during palliative care. Future work will be translational in nature to adapt both assessment and interventions based on this theoretically driven augmentation of palliative care as well as to evaluate whether it provides a conceptual framework that has incremental utility in palliative care planning.

RESUMO

OBJECTIVES: To characterise the restrictiveness of eligibility criteria in contemporary renal cell carcinoma (RCC) trials, using recommendations from the American Society of Clinical Oncology (ASCO)-Friends of Cancer Research (FCR) initiative. METHODS: vPhase I-III trials assessing systemic therapies in patients with RCC starting between 30 June 2012 and 30 June 2022 were identified. Eligibility criteria regarding brain metastases, prior or concurrent malignancies, hepatitis B virus (HBV) or hepatitis C virus (HCV) infection, and human immunodeficiency virus (HIV) infection were identified and stratified into three groups: exclusion, conditional inclusion, and not reported. Descriptive statistics were used to determine the frequency of eligibility criteria. Fisher's exact test or chi-square test were used to calculate their associations with certain trial characteristics. RESULTS: A total of 423 RCC trials were initially identified of which 112 (26.5%) had sufficient accessible information. Exclusion of patients with HIV infection, HBV/HCV infection, brain metastases, and prior or concurrent malignancies were reported in 74.1%, 53.6%, 33.0%, and 8.0% of trials, respectively. In the context of HIV and HBV/HCV infection, patients were largely excluded from trials evaluating immunotherapy (94.4% and 77.8%, respectively). In addition, brain metastases were excluded in trials assessing targeted therapy (36.4%), combined therapy (33.3%), and immunotherapy (22.2%). Exclusion of patients with prior or concurrent malignancies was less frequently reported, accounting for 9.1%, 8.3%, and 5.6% targeted therapy, combined therapy and immunotherapy trials, respectively. CONCLUSION: A substantial proportion of RCC trials utilise restrictive eligibility criteria, excluding patients with fairly prevalent comorbidities. Implementing the ASCO-FCR recommendations will ensure resulting data are more inclusive and aligned with patient populations in the real-world.

RESUMO

We sought to examine differences in anxiety, depression and coping strategies among younger (<64-year old) and older (≥65-year old) patients. Patients were assessed at baseline (T1), mid-point (T2) and on the last day of treatment (T3) using the Hospital Anxiety and Depression Scale and the Ways of Coping. A linear mixed modeling approach was used. The study included 200 patients (gender: 70% women; diagnosis: 30% breast, 22% hematological, 18% gastrointestinal; disease stage: 60% advanced). Older patients who used an emotion-focused coping strategy had a greater decrease in anxiety at T3 compared to those that used problem-focused coping (p = .002).

RESUMO

We sought to determine racial and ethnic differences in perceptions (quality of communication, expectations, and concerns) of germline or somatic DNA sequencing (genomic profiling). Patients with prostate, urothelial, or kidney cancer were surveyed using a questionnaire that assessed previous experience, beliefs, expectations, and concerns regarding genomic profiling. Descriptive statistics and chi-square tests were used to identify factors associated with patients' perceptions of genomic profiling. A total of 150 consecutive patients were enrolled. The majority were male (74%) with a mean age of 68 years old. Most patients underwent somatic testing (54%), 24% undertook germline testing, and 21% undertook both tests. Significant differences were found across racial and/or ethnicity concerning factors that could have influenced patients' decision to pursue genomic profiling, including ability to guide the type of treatment (White: 54.1% vs. other ethnic groups: 43.9%, p = 0.04) and potential to improve treatment response (White: 10.1% vs. other ethnic groups: 22.0%, p = 0.04). Other ethnic group of patients were more concerned about learning that the cancer was less treatable or aggressive (43.8% vs. 27.7%, p = 0.01) and anxious about what would be learnt from genomic profiling (34.4% vs. 21.3, p = 0.01) as compared to White patients. Our findings reinforce the importance of developing culturally tailored education to help patients participate actively in decisions about genomic profiling.

RESUMO

BACKGROUND: We explored changes in perceptions of cure among patients with genitourinary (GU) cancers starting Immune checkpoint inhibitors (ICIs) therapy. MATERIALS AND METHODS: This longitudinal study assessed patients before starting therapy and 3-months later with a questionnaire that included patient perceptions of ICIs and the Patient-Reported Outcomes Measurement Information System (PROMIS) Anxiety scale. General linear modeling was used to investigate changes in expectation of cure over time, and chi-square tests were used to determine the association between expectation of cure and perceptions of ICIs and anxiety. RESULTS: A total of 45 patients were recruited (73% male, 84% diagnosed with renal cell carcinoma). The proportion of patients who possessed an accurate expectation of cure increased over time (55.6%-66.7%, P = .001). An accurate expectation of cure was associated with lower rates of anxiety over time. Patients with inaccurate expectation of cure reported more severe side effects and worse self-reported ECOG score at the follow-up assessment (P = .04). CONCLUSION: We found that patients with GU metastatic cancer treated with ICI therapy have increasingly accurate expectations of cure over time. Accurate expectation of cure is associated with decreased anxiety. Further research is needed to fully explore this dynamic over time and help inform interventions that can help patients develop accurate expectations.

RESUMO

BACKGROUND: There is a lack of consensus regarding the optimal method of assessing health-related quality of life (HR-QOL) among patients with metastatic renal cell carcinoma (mRCC). This study explored the perceived relevance of items that make up the Functional Assessment of Cancer Therapy Kidney Symptom Index-19 (FKSI-19), as judged by patients with mRCC. METHODS: This was a multinational cross-sectional survey. Eligible patients responded to a questionnaire composed of 18 items that assessed the perceived relevance of each item in the FKSI-19 questionnaire. Open-ended questions assessed additional issues deemed relevant by patients. Responses were grouped as relevant (scores 2-5) or nonrelevant (score 1). Descriptive statistics were collated, and open-ended questions were analyzed and categorized into descriptive categories. Spearman correlation statistics were used to test the association between relevance and clinical characteristics. RESULTS: A total of 151 patients were included (gender: 78.1 M, 21.9F; median age: 64; treatment: 38.4 immunotherapy, 29.8 targeted therapy, 13.9 immuno-TKI combination therapy) in the study. The most relevant questions evaluated fatigue (77.5), lack of energy (72.2), and worry that their condition will get worse (71.5). Most patients rated blood in urine (15.2), fevers (16.6), and lack of appetite (23.2) as least relevant. Qualitative analysis of open-ended questions revealed several themes, including emotional and physical symptoms, ability to live independently, effectiveness of treatment, family, spirituality, and financial toxicity. CONCLUSION: There is a need to refine widely used HR-QOL measures that are employed among patients diagnosed with mRCC treated with contemporary therapies. Guidance was provided for the inclusion of more relevant items to patients' cancer journey.

RESUMO

BACKGROUND: This study sought to determine the feasibility and acceptability of a remote geriatric assessment (GA) and implementation (GAIN) program in Brazil. The authors also explored the effect of this program on health-related quality of life (HR-QOL) outcomes 3 months after initiating treatment. METHODS: This is a longitudinal study enrolling older adults (65+ years), diagnosed with any type of solid tumor, scheduled to initiate chemotherapy in a networked Brazilian cancer center. The GA was performed through telehealth. We assessed the feasibility of the remote GA, acceptability to patients, and changes in patient-centered outcomes (HR-QOL, mood, function) from baseline to month 3. Linear mixed model analysis was done, adjusting for age, gender, race, income, and disease stage. RESULTS: Fifty-six patients completed all intended assessments. Notably, the threshold of feasibility was 70% and there was 92% complete adherence. Average age was 76 years old (SD = 7.2). Most patients were female (57%), married (59%), and had a college degree (46%). The most common diagnoses were gastrointestinal (39%) and gynecological cancers (18%); most were diagnosed at an advance disease stage (77%). A total of 32 patients were referred to a remote appointment and 86% followed this recommendation(s). Significant improvement in Functional Assessment of Cancer Therapy - General FACT-G (mean difference, 6.04; p < .001), Geriatric Depression Scale (mean difference, -0.86; p = .008), and instrumental activities of daily living ratio (mean difference, 0.17; p < .001) were found. CONCLUSION: Remote GAIN is feasible and acceptable to older adults with cancer receiving treatment in Brazil. The authors also found significant improvement in HR-QOL outcomes over time. Notably, this GAIN program could guide early detection of chemotherapy toxicity and improving patient-reported outcomes in low-resource environments.

RESUMO

BACKGROUND: The integration of a biopsychosocial screening (BPS) program has been proposed by international agencies to better identify and effectively manage unmet needs among patients with cancer. We sought to evaluate the effect of a BPS program on hospital admissions and length of stay (LOS) among a diverse sample of patients with cancer and receiving treatment in Brazil. METHODS: A retrospective analysis was performed from March 2020 to December 2021. Eligible patients were diagnosed with cancer and were receiving treatment at a private practice in Brazil. Clinical characteristics, participation in the BPS program, hospital admissions, reason, and LOS in hospital were evaluated. We compared the number of hospital admissions and LOS between groups (participation v no participation). T test and Chi-square test were used to test for differences between groups. RESULTS: A total of 1,014 patients were included in the analysis. Baseline clinical characteristics were well balanced between groups (n = 459 patients who participated and n = 555 patients who did not). The median age of patients was 63 years. Breast and hematological cancers were the most common types of cancer; 60% were diagnosed at an advanced disease stage. A smaller proportion of patients who participated in the BPS program were hospitalized compared with patients who did not participate (8% v 32%, P = .001). Patients who participated in the program also spent less days in the hospital compared with patients who did not participate in the program (M = 4.2 days v 9.8 days, P = .001). CONCLUSION: Engagement in a BPS program was associated with reduced hospital admissions and LOS. This study provides novel insight into the potential broader implications of BPS programs for clinical care systems. Future studies are needed to explore the mechanisms behind such associations.

RESUMO

Stereotactic body radiation therapy (SBRT) has been shown to be safe and effective for delaying systemic treatment change among patients with metastatic renal cell carcinoma (mRCC). In this study, we sought to assess the genomic signatures of patients with mRCC who underwent SBRT for oligoprogression. A total of 30 patients with oligoprogressive disease were identified, the majority of whom had clear cell renal cell carcinoma (83.3%) and were receiving first-line treatment (53.3%). Genomic and transcriptomic sequencing were available in 20 and 16 patients, respectively. Duration of systemic treatment (DOT) was categorized as that prior (DOT[P]) and subsequent (DOT[S]) to radiation treatment. The median DOT(P) and DOT(S) were 15.1 and 18.3 mo, respectively, with a median DOT(S)/DOT(P) ratio of 1.4. Patients who had a DOT(S)/DOT(P) ratio of ≥1 had increased expression in pathways related to cell proliferation and development. In contrast, among patients with a ratio of ≤1, the reactive oxygen species pathway was enriched. This study highlights the potential role of genomics and transcriptomics to refine radiation treatment selection in patients with mRCC. PATIENT SUMMARY: In this study, we looked at mutations and genomic expressions among kidney cancer patients who responded better to stereotactic body radiotherapy. We found that enriched expression of certain pathways might play a role in response to radiotherapy.

RESUMO

OBJECTIVE: Fear of cancer recurrence or progression (FCR) is considered one of the most common unmet needs among patients with cancer. This study sought to translate and evaluate the psychometric properties of the Fear of Cancer Recurrence scale (FCR4/7) and Fear of Cancer Recurrence Inventory-Short Form (FCRI-SF). METHODS: This study involved three phases: (1) translation and cultural adaptation of the FCR4/7 and FCRI-SF measures, (2) validity and reliability testing of the Portuguese version of these measures, and (3) examining patient's perceptions of these measures. Eligible patients were diagnosed with localized breast cancer, and patients with metastatic cancer. Descriptive analyses were collated, and psychometric analysis were conducted (confirmatory factor analysis). RESULTS: A total of 200 patients were recruited (100 patients with localized and 100 patients with metastatic cancer). A significant proportion of patients reported moderate to severe FCR (FCR7: 32.0% and FCRI-SF: 43.0%). Female gender, younger age and metastatic cancer were associated with higher levels of FCR. Psychometric analyses suggested that the Portuguese versions of the FCR4/7 and FCRI-SF were valid, unidimensional in nature, with acceptable reliability coefficients across all scales. In a sub-sample qualitative analysis (n = 75), most patients were satisfied with the relevance of both measures. CONCLUSION: Our findings suggest the Portuguese versions of the FCR4/7 and FCRI-SF are valid tools to assess FCR among patients with localized and metastatic cancer. Future research can now extend our understanding of FCR and assess this construct among Portuguese speaking patients, to guide the development of effective and targeted interventions for patients globally.

RESUMO

Since the approval of the COVID-19 vaccines, their safety and efficacy has been widely demonstrated in patients with cancer. However, there remain patients with reservations regarding vaccination. We aimed to assess genitourinary cancer patients' perceptions of the vaccines as well as barriers and influencers of decision-making through the completion of a questionnaire. While vaccine-associated concerns were observed, most patients with genitourinary cancers were willing to receive the vaccine. Moving forward, differing strategies could be considered to enhance patient education on the utility of vaccination in the setting of cancer and beyond.

RESUMO

OBJECTIVE: Previous studies have suggested the benefit of routine screening for biopsychosocial symptoms among patients with cancer. In recognition of the lack of data from low- and middle-income countries, this study sought to test and determine the effect of a mHealth program to screen biopsychological symptoms among patients with advanced breast or gynecological cancer. METHODS: This was a quasi-experimental pre-post study conducted in a public hospital located in central western Brazil. Patients diagnosed with advanced breast of gynecological cancer who were about to initiate chemotherapy treatment at this institution and had access to Internet by smartphone, computer or tablet were invited to participate. Patients received training on using the app Comfort, a program developed to rate their physical and emotional symptoms during the 6-month of the proposed study. Patients were also asked to complete the EuroQOL 5D (EQ-5D-3L) every month. Mann-Whitney U test was used to determine differences among groups of patients (engaged and non-engaged). RM-ANOVA was used to determine the effect of time on mean visual analog scale (VAS) score. RESULTS: A total of 125 patients were recruited (median age = 46.6 years old, 41.6% married). Mostly, patients possessed lower levels of education and had relatively low monthly incomes. Notably, 67.2% of patients engaged with the Comfort program, and few patients (4%) withdrew due to lack of engagement with the program or issues with internet connection. In general, patients who engaged with the program reported improvement in physical and emotional symptoms (p < 0.01), as well as in their overall quality of life (VAS; p = 0.009), compared with patients who did not engage with the program. CONCLUSIONS: This is the first mHealth program developed in Brazil for patients in a low resource setting. Our findings suggest that Comfort could be an effective resource to assist patients and health care providers track symptoms and improve patients' quality of life.

RESUMO

BACKGROUND: Relinquishing control (RC) of outcomes to God is a long-standing form of religious coping with serious illness. Placing cancer outcomes "in God's hands" has been positively related to coping and quality of life (QOL). However, the mechanisms involved in this relationship have not been established. A serial mediation model [i.e., RC (X)-Meaning/Peace (M1)-Coping Efficacy (M2)-Symptoms, Physical QOL, Functional QOL (Ys)] tested the hypothesis that Meaning/Peace alone and in conjunction with coping would mediate the RC-QOL relationship. METHOD: 548 persons with a cancer diagnosis completed the Religious Problem-Solving Scale (RPSS), FACIT-Sp Meaning and Peace Scales, Cancer Behavior Inventory (coping efficacy), and measures of Physical Quality of Life (PQOL), Functional Quality of Life (FQOL) and Symptoms. RESULTS: As hypothesized, the single mediation effects of Meaning/Peace were significant [Indirect Effects: PQOL: .23 (95% CI: 0.15, 0.34); FQOL: 0.46 (95% CI: 0.33, 0.61); Symptoms: -0.18 (95% CI: -0.27, -0.10)]. In addition, mediation was confirmed for the serial mediation model (i.e., Meaning/Peace - Coping Efficacy as serial mediators) with significant indirect effects [Indirect Effects: PQOL: 0.37 (95% CI: 0.27, 0.48); FQOL: 0.57 (95% CI: 0.42, 0.72); Symptoms: -0.25 (95% CI: -0.35, -0.17)]. CONCLUSIONS: In the mediation models tested, the RC-QOL and RC-Symptoms relationships were mediated by the confluence of a sense of peace perhaps due to patients' feelings that outcomes were "in God's hands" and a sense of coherence between their current situation and a spiritually-based meaning system. Meaning/Peace was also related to coping efficacy, suggesting that these mediating constructs could be used to inform evidence-based interventions, such as Meaning-Centered therapies, that are sensitive to the belief systems of cancer patients and enhance QOL.

RESUMO

INTRODUCTION: Health agencies and guidelines have proposed various recommendations regarding breast and prostate cancer screening intervals for older adults. However, there is limited data about factors that could impact older individuals' adherence to these guideline-based intervals. This study emphasized the differences in screening rates between men and women undergoing screening for breast (mammogram) and prostate (prostate-specific antigen [PSA] test) cancer. It also investigated the socio-demographic and emotional factors associated with screening time intervals. MATERIALS AND METHODS: This cross-sectional design study used data from the National Social Life Health and Aging Project Wave 3 (NSHAP-W3, 2015). The outcome measures were screening time intervals (PSA test or mammogram). Individuals were asked, "About how long has it been since you last had a screening?" Response categories ranged from 1 = within the past year to 5 = never. Differences in screening time intervals were evaluated and displayed by age group (PSA vs. mammogram). The association between the outcome measures and participants' characteristics was evaluated via ordinal logistic regression. RESULTS: There were 2320 participants included: 52% women and 48% men. They had a mean age of 66.9 years old, were mostly White (74%) and college graduates (68%). The average time interval between screenings was greater for PSA testing than mammography (mean [M] = 2.28 vs. M = 1.89, p < 0.001). The middle age groups (PSA: 60-79 and mammogram: 65-74), had significantly more frequent screenings compared to the youngest group (50-54). In contrast, older (80+) individuals did not display shorter screening time intervals compared to the youngest group. Furthermore, shorter time intervals between screenings were associated with higher household income (mammogram: odds ratio [OR] = 0.804; PSA: OR = 0.785, p < 0.05), African American descent (mammogram: OR = 0.458, p < 0.001), and higher frequency of physical activity (PSA: OR = 0.921, p = 0.030). Lastly, women who responded "yes" to skipping care due to lack of insurance reported longer periods between mammograms (OR = 1.784, p = 0.002). DISCUSSION: Findings from this real-world US population representative database highlight the role of age, income, and insurance in the timing between screenings; participants aged between 60 and 79 years old, African American women, and physically active men are more likely to pursue earlier screening. These results emphasize the importance of socioeconomic and lifestyle factors when seeking to impact screening timing.

RESUMO

BACKGROUND: Colorectal cancer (CRC) is the 2nd leading cause of cancer death in the United States. The American Cancer Society (ACS) Nutrition and Physical Activity Guidelines are associated with longer survival among CRC survivors, but few report behaviors consistent with the guidelines. METHODS: The Tools To Be Fit study, based on the Multiphase Optimization Strategy (MOST) framework, is a full factorial experimental to optimize a remotely delivered 48-week diet and physical activity intervention for non-metastatic CRC survivors. The intervention includes a core component (booklet and personal report). CRC survivors (N = 400) are additionally randomly assigned to one of 16 combinations of four candidate components, each with 2 options: 1) text messaging (on/off); 2) self-monitoring modality (digital/paper); 3) health coaching (on/off); and 4) support person coaching (on/off). OUTCOMES: Our primary outcome is adherence to the ACS guidelines after 48 weeks using a score that includes physical activity from accelerometers, dietary intake from a food frequency questionnaire, and body mass index (BMI) measured by a technician. Secondary outcomes include the ACS score after 24 weeks and score components at 24 and 48 weeks. Exploratory outcomes include adherence and change in Social Cognitive Theory constructs. We will explore moderation by sociodemographic, clinical, and psychological/behavioral factors; and change in the ACS score in relation to change in levels of insulin, insulin sensitivity, inflammation, gut microbiome structure, fatigue, depression, and sleep disturbance. DISCUSSION: The proposed study aims to inform a randomized controlled trial to determine whether an optimized intervention reduces risk of recurrence among CRC survivors.

RESUMO

Chemotherapy and radiotherapy are first-line treatments in the management of advanced solid tumors. Whereas these treatments are directed at eliminating cancer cells, they cause significant adverse effects that can be detrimental to a patient's quality of life and even life-threatening. Diet is a modifiable risk factor that has been shown to affect cancer risk, recurrence, and treatment toxicity, but little information is known how diet interacts with cancer treatment modalities. Although dietary interventions, such as intermittent fasting and ketogenic diets, have shown promise in pre-clinical studies by reducing the toxicity and increasing the efficacy of chemotherapeutics, there remains a limited number of clinical studies in this space. This review surveys the impact of dietary interventions (caloric restriction, intermittent and short-term fasting, and ketogenic diet) on cancer treatment outcomes in both pre-clinical and clinical studies. Early studies support a complementary role for these dietary interventions in improving patient quality of life across multiple cancer types by reducing toxicity and perhaps a benefit in treatment efficacy. Larger, phase III, randomized clinical trials are ultimately necessary to evaluate the efficacy of these dietary interventions in improving oncologic or quality of life outcomes for patients that are undergoing chemotherapy or radiotherapy.

RESUMO

Herein we report the impact of localized delivery of an anti-mouse PD-1-specific monoclonal antibody (aPD1) on Renca tumors in the resulting T cell responses and changes in broader immune gene expression profiles. Renca is a BALB/c mice syngeneic tumor that has been used to model human renal cell carcinoma In this study, T cell subsets were examined in tumors and draining lymph nodes of mice treated with localized PD-1 with and without the addition of adenosine deaminase (ADA), an enzyme that catabolizes adenosine (ADO), identified as an immune checkpoint in several types of human cancers. The biologics, aPD1, or aPD1 with adenosine deaminase (aPD1/ADA), were formulated with the self-assembling peptides Z15_EAK to enhance retention near the tumor inoculation site. We found that both aPD1 and aPD1/ADA skewed the local immune milieu towards an immune stimulatory phenotype by reducing Tregs, increasing CD8 T cell infiltration, and upregulating IFNÉ£. Analysis of tumor specimens using bulk RNA-Seq confirmed the impact of the localized aPD1 treatment and revealed differential gene expressions elicited by the loco-regional treatment. The effects of ADA and Z15_EAK were limited to tumor growth delay and lymph node enlargement. These results support the notion of expanding the use of locoregional PD-1 blockade in solid tumors.

RESUMO

A 40-year-old unmarried Brazilian woman, Ms A, received a diagnosis of papillary renal cell carcinoma (RCC) in February 2020; she underwent nephrectomy the following month. In August, she began to experience generalized pain with subsequent scans revealing metastatic disease to the supraclavicular lymph node, liver, and vagina. In October 2020, Ms A started first-line systemic combination treatment with nivolumab (Opdivo; 3 mg/kg) plus ipilimumab (Yervoy; 1 mg/kg) every 3 weeks for 4 doses, followed by nivolumab (3 mg/kg) every 2 weeks, to be taken for 2 years. In April 2021, follow-up testing revealed a partial response to therapy, and a complete response was evident in August 2021. Ms A was first screened for biopsychosocial distress by the supportive care team in October 2020, and she completed the Edmonton Symptom Assessment System (ESAS) evaluation.During her fourth cycle of treatment in October 2020, the patient was assessed with the ESAS. During her medical visits, Ms A also expressed concern regarding her physical symptoms and admitted frequent self-monitoring for signs of recurrence or progression. Her oncologist prescribed tramadol for pain and the supportive care team recommended increased engagement in physical activity. Upon further assessment, the patient reported a belief that her psychosocial symptoms, worry about recurrence or progression, and time spent self-monitoring were a normal part of her cancer experience.
