RESUMEN

BACKGROUND: Renal cell carcinoma (RCC), one of the most fatal urologic tumors, accounts for approximately 3% of all adult cancers and exhibits a high metastatic index at diagnosis and a high rate of relapse. Radical or partial nephrectomy is a curative option for nonmetastatic RCCs. Targeted therapy has been shown to improve the survival of patients with metastatic RCCs. However, the underlying cellular and molecular events associated with RCC pathogenesis are not well known. METHODS: To investigate the clinical role of the transcription factor activator protein (AP)-2α in RCC, methylated CpG island recovery assays and microarray analysis were employed. COBRA and RT‒qPCR assays were performed to assess AP-2α expression in RCC. RESULTS: A negative correlation was noted between AP-2α mRNA expression levels and methylation status. Multivariate analyses showed that AP-2α mRNA was a major risk factor not only for overall and disease-free survival in RCC but also for disease-free survival in clear cell RCC. CONCLUSIONS: Our results indicated that AP-2α expression was deregulated in RCC and associated with overall patient survival and disease-free survival. Such findings suggest that AP-2α might play an important role in the pathogenesis of RCC.

RESUMEN

This is a retrospective cohort study by analyzing a multi-institutional electronic medical records database in Taiwan to compare long-term effectiveness and risk of major adverse cardiac events (MACE) in chemotherapy-naïve metastatic castration-resistant prostate cancer (mCRPC) patients treated with enzalutamide (ENZ) or abiraterone (AA). Patients aged 20 years and older and newly receiving androgen receptor targeted therapies ENZ or AA from September 2016 to December 2019 were included. We followed patients from initiation of therapies to the occurrence of outcomes (prostate-specific antigen (PSA) response rate, PSA progression free survival (PFS), overall survival (OS), and MACE), death, the last clinical visit, or December 31, 2020. We performed multivariable Cox proportional hazard models to compare ENZ and AA groups for the measured outcomes. A total of 363 patients treated with either ENZ (n = 157) or AA (n = 206) were identified. The analysis found a significantly higher proportion of patients with a PSA response rate higher than 50% among those receiving ENZ than among those receiving AA (ENZ vs AA: 75.80% vs 63.59%, P = .01). However, there was no significant difference in PSA PFS (adjusted hazard ratio: 0.86; 95% CI 0.63-1.17) and OS (0.68: 0.41-1.14) between the use of ENZ and AA in chemotherapy-naïve mCRPC patients. Regarding the cardiovascular (CV) safety outcome, there was a significantly lower risk of MACE in patients receiving ENZ, compared to patients receiving AA (0.20: 0.07-0.55). The findings suggest that enzalutamide may be more efficacious for PSA response and suitable for chemotherapy-naïve mCRPC patients with high CV risk profile.

RESUMEN

BACKGROUND: Lymph node invasion is associated with poor outcome in patients with renal cell carcinoma (RCC). PATIENTS AND METHODS: Patients with RCC within a single center from 2001 to 2018 were retrospectively obtained from the Chang Gung Research Database. Patient gender, physical status, Charlson Comorbidity Index, tumor side, histology, age at diagnosis, and body mass index (BMI) were compared. The overall survival (OS) and cancer-specific survival (CSS) of each group were estimated using the Kaplan-Meier method. Log-rank tests were used to compare between the subgroups. RESULTS AND CONCLUSIONS: A total of 335 patients were enrolled, of whom 76 had pT3N0M0, 29 had pT1-3N1M0, 104 had T1-4N0M1, and 126 had T1-4N1M1 disease. Significant OS difference was noted between pT3N0M0 and pT1-3N1M0 groups with 12.08 years [95% confidence interval (CI), 8.33-15.84] versus 2.58 years (95% CI, 1.32-3.85), respectively (P < 0.005). No significant difference was observed in OS between pT1-3N1M0 and T1-4N0M1 groups with 2.58 years (95% CI, 1.32-3.85) versus 2.50 years (95% CI, 1.85-3.15, P = 0.72). The OS of N1M1 group was worse than that of N0M1 group with 1.00 year (95% CI, 0.74-1.26) versus 2.50 years (95% CI, 1.85-3.15, P < 0.05). Similar results were also observed in CSS. In summary, we claim that RCC with lymph node (LN) invasion should be reclassified as stage IV disease in terms of survival outcome.

RESUMEN

BACKGROUND: Urinary incontinence is a common complication among patients with prostate cancer who have undergone radical prostatectomy. Guided by social cognitive theory and a framework for the recovery of health and well-being, we propose to develop and test a self-management intervention for patients with prostate cancer who experience urinary incontinence after undergoing radical prostatectomy. METHODS: In this study, a self-management intervention for urinary incontinence (SMI-UI) is developed, comprising a mobile self-management application, a self-management handbook, and professional support. The feasibility, acceptability, and effectiveness of this intervention will be assessed. Patient data from the urology departments of two hospitals will be collected through convenience sampling by adopting an experimental, parallel, and random assignment research design. Patients experiencing urinary incontinence after undergoing radical prostatectomy will be invited to participate. After completing the pretest questionnaire, patients will be randomly divided into the experimental and attention control groups. The experimental group will undergo a 12-week SMI-UI, whereas the attention control group will receive an intervention consisting of a single dietetic education information package. The two groups will be tested 12 and 16 weeks after the pretest. In this study, we recorded the sociodemographic and clinical variables; recruitment rate; retention rate; satisfaction with the intervention; cancer-related self-efficacy; urination symptoms and disturbance; social participation and satisfaction; resilience; and demoralization. TRIAL REGISTRATION: ClinicalTrials.gov ID: NCT05335967 [date of registration 04-04-2022].

RESUMEN

OBJECTIVE: To assess the relationship between resilience and quality of life (QOL) of kidney cancer patients, including influencing factors. METHODS: Based on a cross-sectional study design, participants (N = 103) were recruited from patients who were admitted to the urology clinic of a medical center in Taiwan between April 2020 and January 2021. Data collection was accomplished via a questionnaire. The study variables included demographic information, disease attributes, happiness level, depression, cancer-related self-efficacy, resilience, and QOL. One-way analysis of variance, Pearson correlation coefficients, independent-sample t-tests, hierarchical regression, and process analysis were the statistical methods used to analyze the data. RESULTS: Kidney cancer patients who were less depressed exhibited better cancer-related self-efficacy and have better resilience. In non-depressed individuals, higher levels of happiness and better resilience resulted in better QOL. Resilience is a mediator that affects the relationship between depression and QOL. CONCLUSIONS: Patients with better emotional state experience better resilience and QOL. Patients' better cancer-related self-efficacy is related to better resilience while better resilience is associated with better QOL. Clinical care providers need to evaluate and improve cancer-related self-efficacy, emotional state, and resilience of kidney cancer patients, which will improve their resilience and QOL.

RESUMEN

OBJECTIVE: This study aimed to investigate psychological resilience and demoralisation and their predictors and mediators in prostate cancer survivors (PCSs). METHODS: A cross-sectional research design was used. PCSs (N = 122; mean time since diagnosis = 54.79 months, range in 13 years and 2 months) were recruited using convenience sampling at the outpatient department of a hospital in Taiwan. Data collection was conducted using self-report structured questionnaires, including one for demographic and disease characteristics, the Expanded Prostate Cancer Index Composite, Cancer Survivors' Self-Efficacy Scale, Connor-Davidson Resilience Scale and the Demoralisation Scale. RESULTS: In PCSs, a lower most-recent level of prostate-specific antigen and higher cancer-specific self-efficacy were associated with better psychological resilience. Further, fewer hormonal, bowel and urinary symptoms and bother; higher cancer-specific self-efficacy; and better psychological resilience were associated with less demoralisation. Cancer-specific self-efficacy was a mediator for the relationship between urinary symptoms and bother and demoralisation, while psychological resilience mediated the relationship between cancer-specific self-efficacy and demoralisation. CONCLUSIONS: The results reveal that cancer-specific self-efficacy is a protective factor against demoralisation and increases psychological resilience in PCSs. Better psychological resilience and fewer physical symptoms and bother are associated with less demoralisation in PCSs.

RESUMEN

BACKGROUND: We aimed to determine whether cardiovascular (CV) risk in patients with prostate cancer (PCa) differs between those who receive gonadotropin-releasing hormone (GnRH) agonist (GnRHa) therapy and those who receive GnRH antagonist therapy. METHODS: Using the Taiwan National Health Insurance Research Database, we analyzed data by comparing 666 participants receiving GnRH antagonists and 1332 propensity score-matched participants treated with GnRHa in a 1:2 fashion during the period from May 1, 2015, to September 30, 2018. Cox proportional-hazards models were used to estimate the treatment effect on CV outcomes. Furthermore, we conducted an in vitro study to investigate the effect of a GnRHa (leuprolide) or a GnRH antagonist (degarelix) on matrix metalloproteinase-9 (MMP-9) expression and invasion ability in THP-1 differentiated macrophages. RESULTS: GnRH antagonist therapy was associated with a lower risk of composite CV events of myocardial infarction, ischemic stroke, or CV death (hazard ratio [HR], 0.48; 95% confidence interval [CI], 0.25-0.90) than GnRHa therapy, with a mean follow-up period of 1.21 years. Significantly lower risks of CV death (HR, 0.21; 95% CI, 0.06-0.70) and all-cause mortality (HR, 0.77; 95% CI, 0.61-0.97) were observed in the GnRH antagonist group. In the in vitro study, leuprolide, but not degarelix, significantly increased the expression of MMP-9 activity and the invasive ability of THP-1 differentiated macrophages through gelatin zymography and the matrix invasion assay, respectively. CONCLUSION: GnRH antagonists were associated with reduced risk CV events compared with the GnRHa among patients with PCa, which may be through effects on macrophages.

RESUMEN

AIMS: To understand the effectiveness of a couple-based psychosocial information package (PIP) and multimedia psychosocial intervention (MPI) on patients with prostate cancer and their partners. DESIGN: A random assignment and quasi-experimental design were used. METHODS: From August 2015-March 2018, 103 newly diagnosed patients with prostate cancer and their partners were divided into a control group (CG) (N = 50), PIP group (N = 25) and MPI group (N = 28). The CG received usual care, the PIP group received information manuals and telephone counselling for 6-week and the MPI group received multimedia films and manuals and professional support for 6 weeks. The three groups were posttested 6, 10, 18 and 24 weeks after the pre-test. The outcome measurements included disease appraisals, emotion status, relationship satisfaction, health-related quality of life (HRQOL) and satisfaction with MPI. RESULTS/FINDINGS: Partners in the MPI and PIP groups experienced significant improvements in positive and negative affect or mental HRQOL as compared with the CG. The effectiveness of MPI and PIP on negative affect, mental HRQOL, however, were not statistically significant in patients with prostate cancer. Nevertheless, patients were satisfied with the MPI. CONCLUSION: Nurses can provide different types of interventions for partners, depending on personal preferences and available resources. IMPACT: There is a lack of studies that focus on the effectiveness of couple-based psychosocial intervention on both the patients with prostate cancer and their partners in Asia. Partners in the multimedia psychosocial intervention group and psychosocial information package group experienced improvements in positive affect, negative affect or health-related quality of life as compared with the control group. Patients in both intervention groups experienced similar negative affect and health-related quality of life as compared with the control group. The couple-based psychosocial interventions can be provided by nurses based on partners' preferences and available resources.

RESUMEN

Immune checkpoint inhibitors (ICIs) are a novel treatment option for cancer therapy, which help direct the immune system to recognize and target cancer cells. ICIs have been shown to provide significant mortality benefits for cancer patients, but they are also associated with immune-mediated toxicity. Unlike most immune-related adverse events, which are a common occurrence, reversible and can be treated effectively with glucocorticoid therapy, ICI-associated cardiotoxicities are uncommon, with serious complications and a relatively high mortality even when treated with glucocorticoids. ICI-associated cardiotoxicity can manifest in various ways, including myocarditis, arrhythmias and conduction disease, pericardial disease, myocardial infarction, non-inflammatory cardiomyocyte dysfunction, and even Takotsubo-like cardiomyopathy. The present review summarizes the current understanding of ICI-associated cardiotoxicities, examining the epidemiology and timing of onset, as well as their clinical presentation, diagnostic modalities, pathophysiology, clinical management and outcomes. Although the literature describing ICI-associated cardiotoxicity remains limited to case reports, case series and early clinical trials, strategies for the surveillance, diagnosis and management of this potentially fatal cardiovascular complication of cancer therapy have been proposed.

RESUMEN

Cellulitis is a common infection of the skin and soft tissue. Susceptibility to cellulitis is related to microorganism virulence, the host immunity status and environmental factors. This retrospective study from 2001 to 2013 investigated relationships between the monthly incidence rate of cellulitis and meteorological factors using data from the Taiwanese Health Insurance Dataset and the Taiwanese Central Weather Bureau. Meteorological data included temperature, hours of sunshine, relative humidity, total rainfall and total number of rainy days. In otal, 195 841 patients were diagnosed with cellulitis and the incidence rate was strongly correlated with temperature (γS = 0.84, P < 0.001), total sunshine hours (γS = 0.65, P < 0.001) and total rainfall (γS = 0.53, P < 0.001). The incidence rate of cellulitis increased by 3.47/100 000 cases for every 1° elevation in environmental temperature. Our results may assist clinicians in educating the public of the increased risk of cellulitis during warm seasons and possible predisposing environmental factors for infection.

RESUMEN

AIMS: To explore health-related quality of life (HRQOL) and its individual or mutual influences in people with prostate cancer and their spouses. BACKGROUND: Few studies have explored the influence of prostate cancer-specific anxiety of these people and their spouses on their individual or mutual HRQOL. DESIGN: Repeated-measures design. METHODS: Data on 48 dyadic of people and their spouses were collected from August 2015 - December 2016. Before the people' treatment for prostate cancer, the first data collection occurred for the people and their spouses. The second to fifth data collections were conducted 6, 10, 18, and 24 weeks after the initial measurement. The variables concerned health status, marital satisfaction, positive affect, negative affect, prostate cancer-specific anxiety, and HRQOL. The Actor-Partner-Interdependence Model was adopted for data analysis. RESULTS: The people who had better physical HRQOL were those with good self-reported health status, higher positive affect and lower prostate cancer-specific anxiety. Better physical HRQOL was observed in the spouses who had good self-reported health status and had lower prostate cancer-specific anxiety. The people with localized cancer stages and lower negative affect had a better mental HRQOL. Better mental HRQOL was detected in spouses who had higher marital satisfaction, higher positive affect and lower negative affect. CONCLUSION: Nurses can improve the HRQOL of people and their spouses by implementing activities that promote health and energy and reduce stress and by administering a mindfulness intervention.

RESUMEN

OBJECTIVES: To analyze and present the demography, clinical behavior, especially the risk factors of tumor hemorrhage and management of sporadic angiomyolipoma (SAML), tuberous sclerosis complex associated angiomyolipoma (TSCAML) and epithelioid angiomyolipoma (EAML) in our institution. METHODS: A retrospective study of 587 patients who were diagnosed with renal angiomyolipoma in our institution between January 2000 and May 2015 was done. The AMLs were diagnosed by ultrasonography, CT, or MRI. EAML was confirmed by histopathology. Medical records and follow-up results were analyzed using the SPSS version 22 software. RESULTS: Out of 587 cases of renal AMLs, 87.4% were SAMLs, 8.7% were TSCAMLs and 3.9% were EAMLs. Most of the AML patients were asymptomatic. The most common presenting symptoms included flank pain and abdominal pain. The median tumor size of SAML, TSCAML, EAML were 4.7, 2.7, 10.5 cm respectively. Approximately half of SAMLs were conservatively treated, almost all TSCAMLs were treated conservatively, while all EAMLs were surgically treated. The median tumor size of hemorrhagic SAML cases was 8 cm versus non-hemorrhagic cases of 4.1 cm. The optimal cut-off point on the ROC curve for predicting SAML tumor hemorrhage was 7.35 cm. CONCLUSION: A larger tumor size, younger patient's age and higher BMI value correlated with a higher risk of tumor hemorrhage. For tumor sizes less than 7.35 cm, we recommend active surveillance or TAE for hemorrhage prevention. We also suggest that surgical management should be considered for patients with tumors larger than 7.35 cm, symptomatic and progressive AML, or suspicious EAML.

RESUMEN

BACKGROUND: Electronic learning (e-learning) through mobile technology represents a novel way to teach emergent otorhinolaryngology-head and neck surgery (ORL-HNS) disorders to undergraduate medical students. Whether a cognitive style of education combined with learning modules can impact learning outcomes and satisfaction in millennial medical students is unknown. OBJECTIVE: The aim of this study was to assess the impact of cognitive styles and learning modules using mobile e-learning on knowledge gain, competence gain, and satisfaction for emergent ORL-HNS disorders. METHODS: This randomized controlled trial included 60 undergraduate medical students who were novices in ORL-HNS at an academic teaching hospital. The cognitive style of the participants was assessed using the group embedded figures test. The students were randomly assigned (1:1) to a novel interactive multimedia (IM) group and conventional Microsoft PowerPoint show (PPS) group matched by age, sex, and cognitive style. The content for the gamified IM module was derived from and corresponded to the textbook-based learning material of the PPS module (video lectures). The participants were unblinded and used fully automated courseware containing the IM or PPS module on a 7-inch tablet for 100 min. Knowledge and competence were assessed using multiple-choice questions and multimedia situation tests, respectively. Each participant also rated their global satisfaction. RESULTS: All of the participants (median age 23 years, range 22-26 years; 36 males and 24 females) received the intended intervention after randomization. Overall, the participants had significant gains in knowledge (median 50%, interquartile range [IQR]=17%-80%, P<.001) and competence (median 13%, IQR=0%-33%, P=.006). There were no significant differences in knowledge gain (40%, IQR=13%-76% vs 60%, IQR=20%-100%, P=.42) and competence gain (0%, IQR= -21% to 38% vs 25%, IQR=0%-33%, P=.16) between the IM and PPS groups. However, the IM group had a higher satisfaction score (8, IQR=6-9 vs 6, IQR=4-7, P=.01) compared with the PPS group. Using Friedman's two-way nonparametric analysis of variance, cognitive styles (field-independent, field-intermediate, or field-dependent classification) and learning modules (IM or PPS) had significant effects on both knowledge gain (both adjusted P<.001) and satisfaction (both adjusted P<.001). CONCLUSIONS: Mobile e-learning is an effective modality to improve knowledge of emergent ORL-HNS in millennial undergraduate medical students. Our findings suggest the necessity of developing various modules for undergraduate medical students with different cognitive styles.

RESUMEN

It has been suggested that stress stimuli from the microenvironment maintain a subset of tumor cells with stem-like properties, including drug resistance. Here, we investigate whether Sp1, a stress-responsive factor, regulates stemness gene expression and if its inhibition sensitizes cancer cells to chemotherapy. Hydrogen peroxide- and serum deprivation-induced stresses were performed in glioblastoma (GBM) cells and patient-derived cells, and the effect of the Sp1 inhibitor mithramycin A (MA) on these stress-induced stem cells and temozolomide (TMZ)-resistant cells was evaluated. Sp1 and stemness genes were not commonly overexpressed in clinical GBM samples. However, their expression was highly induced by stress stimuli. Using MA, we demonstrated Sp1 as a critical stemness-related transcriptional factor protecting GBM cells against stress- and TMZ-induced death. Thus, Sp1 inhibition may prevent recurrence of malignant cells persisting after primary therapy.

RESUMEN

AIMS AND OBJECTIVES: To determine the individual and mutual predictors of the marital satisfaction of couples in which the husband experienced prostate cancer. BACKGROUND: Marital satisfaction of patients with prostate cancer has been insufficiently studied in Asian countries as compared with Western countries. DESIGN: This study used a prospective and repeated-measures design. METHODS: Seventy Taiwanese couples in which the husband had prostate cancer completed measures at 6 and 12 months post-treatment. Assessments of physical symptoms, marital satisfaction, coping behaviour and psychological distress were made. Multiple linear regression was used to analyse the data. RESULTS: The marital satisfaction of patients with prostate cancer and that of their spouses were significantly correlated. At 6 months, spouses' marital satisfaction, patients' appraisal of prostate cancer as a threat and patients' serum prostate-specific antigen levels were found to be the predictors of patients' marital satisfaction. Furthermore, patients' marital satisfaction and their spouses' psychological distress were predictors of spouses' marital satisfaction. At 12 months, spouses' marital satisfaction and patients' appraisal of prostate cancer as harm were predictors of patients' marital satisfaction. Finally, spouses' marital satisfaction (at 6 months) and appraisal of prostate cancer as a threat were predictors of spouses' marital satisfaction. CONCLUSIONS: At 6 months post-treatment, patients' and spouses' marital satisfaction will influence each other. However, at 12 months, patients' marital satisfaction exerts an insignificant effect on spouses' marital satisfaction. Moreover, patients' serum prostate-specific antigen level or the negative appraisal of prostate cancer affects their marital satisfaction. Spouses' marital satisfaction is affected by psychological distress and their negative appraisal of prostate cancer. RELEVANCE TO CLINICAL PRACTICE: The results can be used to develop interventions for prostate cancer couples. Such an intervention can be used to modify couples' appraisal of prostate cancer by changing incorrect thinking or to ease the psychological distress to improve marital satisfaction.

RESUMEN

We evaluated changes in psychosocial adjustment over time and its associated factors in prostate cancer patients. A total of 69 patients with prostate cancer were surveyed at pre-diagnosis, 1 month and 6 months post-treatment. The questionnaires distributed to the patients consisted of the Psychosocial Adjustment to Illness Scale and the UCLA Prostate Cancer Index. The generalized estimating equations were used to analyse the collected data. The results of adjustments to psychological distress, the domestic environment and the social environment worsened post-treatment. However, the adjustment to health-care orientation was worst at the time of pre-diagnosis and improved during post-treatment. Patients who perceived an unfavourable health status reported poor adjustment in psychological distress. Patients exhibiting poor urinary function poorly adjusted to the domestic environment. Patients with sexual dysfunction exhibited poor adjustment to the social environment. Patients with low education demonstrated poor adjustment to health-care orientation. Further studies should assess the psychosocial adjustment among prostate cancer patients and provide interventions following pre-diagnosis.

RESUMEN

PURPOSE: Nephroureterectomy with bladder cuff excision may not be sufficient as monotherapy for patients with pT3N0M0 upper tract urothelial carcinoma. The efficacy of postoperative adjuvant chemotherapy in this setting remains controversial. We evaluated the efficacy of adjuvant chemotherapy for patients with pT3N0M0 upper tract urothelial carcinoma in overall, cancer specific and recurrence-free survival. MATERIALS AND METHODS: We retrospectively reviewed records on 171 consecutive patients with pT3N0M0 upper tract urothelial carcinoma treated with radical nephroureterectomy between 2004 and 2014 at 2 branches of the same institution. Postoperative adjuvant chemotherapy was gemcitabine/cisplatin or cisplatin/fluorouracil/leucovorin. Overall, cancer specific and recurrence-free survival rates were estimated using the Kaplan-Meier method. The values of prognostic factors were evaluated by Cox regression analysis. RESULTS: Postoperative adjuvant chemotherapy was administered in 60 patients vs nonadjuvant therapy in 111 patients. Median followup was 35.8 months. Between the adjuvant and nonadjuvant treatment groups there were statistically significant differences in 5-year cancer specific (80.5% vs 57.6%, p = 0.010) and recurrence-free (74.4% vs 52.9%, p = 0.026) survival rates. Although there was no statistically significant difference in overall survival (71.9% vs 49.0%, p = 0.072), there was a trend of better overall survival in the patients who received postoperative chemotherapy. On multivariable analysis age (p = 0.018), tumor location (p = 0.003) and adjuvant chemotherapy (p = 0.001) were predictors of cancer specific survival. CONCLUSIONS: Adjuvant chemotherapy improves cancer specific and recurrence-free survival in patients with pT3N0M0 upper tract urothelial carcinoma after radical nephroureterectomy.

RESUMEN

AIMS AND OBJECTIVES: To identify the changes and associated factors in decisional conflict and regret in patients with localised prostate cancer up to six months postprimary treatment. BACKGROUND: Various treatments of differing qualities can be used for patients with localised prostate cancer; these treatments may cause conflicts in treatment decision-making and post-treatment regret. DESIGN: A quantitative longitudinal study. METHODS: A total of 48 patients were recruited from a 3700-bed medical centre in northern Taiwan and assessed at pretreatment and one and six months post-treatment. Demographic characteristics, clinical information and results from the psychosocial adjustment to illness scale, decisional conflict scale and decision regret scale were collected. Data were analysed based on the generalised estimating equations models. RESULTS: The overall decisional conflict substantially improved over time. However, the feeling of being less informed was high and did not improve considerably during the study period. Education level, decision preferences and psychosocial adjustment were associated with decisional conflict and influenced decision-making. The feeling of ineffective decision-making and decisional regret was low, post-treatment. Psychosocial adjustment was associated with effective decision-making and decisional regret. CONCLUSION: In patients with localised prostate cancer, decisional conflict reduced considerably up to six months post-treatment. Moreover, the patients were satisfied with their treatment decision-making and believed that they had made the correct choice up to six months post-treatment. However, patients may have experienced feelings of being less informed pre- and post-treatment, particularly those with lower education levels, a preference for passive roles, or inferior psychosocial adjustment. Consequently, health professionals must provide adequate medical information and psychosocial intervention to help patients in the decision-making process. RELEVANCE TO CLINICAL PRACTICE: Nurses and healthcare providers must provide localised prostate cancer patients with adequate information and psychosocial intervention to reduce decisional conflict.

RESUMEN

BACKGROUND: The reliability and validity of the traditional Chinese version of the Cancer Survivors' Self-Efficacy Scale (CS-SES-TC) has not been assessed. OBJECTIVE: To assess the psychometric properties of the Traditional Chinese version of the CS-SES-TC. METHODS: Participants were recruited from the outpatient departments of a hospital in Taiwan. A single questionnaire was administered to 300 genitourinary cancer survivors. The scales included in the initial questionnaire were the CS-SES-TC, the General Self-Efficacy Scale, the Center for Epidemiologic Studies Depression Scale (CES-D), and the Functional Assessment of Cancer Therapy-General scale (FACT-G). Data obtained from 300 survivors were used to confirm the structure through confirmatory factor analysis (CFA). RESULTS: The CFA results indicate that the 11-item CS-SES-TC is consistent with the original scale. Furthermore, it was identified as a unidimensional scale, with the model showing acceptable goodness-of-fit (CFI = 0.99, TLI = 0.97). The factor loading of each item in the CS-SES-TC was above 0.6 and had convergent validity. Based on multiple-group CFA testing, the change (ΔCFI) between the unconstrained and constrained models was ≤ 0.01, indicating that measurement invariance holds for gender. The participants' CS-SES-TC scores were positively correlated with their FACT-G scores and negatively correlated with their CES-D scores. The scales exhibited concurrent validity and discriminant validity. The CS-SES-TC had a Cronbach's α in the range of .97-.98. CONCLUSION: The CS-SES-TC had acceptable reliability and validity. Healthcare workers can use this scale for ongoing assessment of the cancer-related self-efficacy of cancer survivors.

RESUMEN

This study aims to examine changes in body image (BI) over time and factors related to BI among patients with prostate cancer who receive hormone therapy (HT). A cross-sectional design and longitudinal design were utilized. Patients with prostate cancer who received HT were recruited from the urology outpatient departments in two hospitals in Taiwan between August 2017 and December 2020. Cross-sectional data were collected from 177 patients who had started HT for prostate cancer. Longitudinal data were collected from 34 newly diagnosed patients before receiving HT and at 1, 3, 6, and 12 months after HT. The variables measured included hormonal symptoms and distress, self-efficacy, and BI. The results showed that BI dissatisfaction ranged from 6.1% to 17.2%. Hormonal symptoms and distress (e.g. lack of vitality) were correlated with BI dissatisfaction. Education on the side effects of HT and coping strategies can be provided to patients to prevent BI dissatisfaction.
