RESUMO

OBJECTIVE: In this retrospective investigation of patient pathways to psycho-oncological treatment (POT), we compared the number of POT referrals before and after implementation of electronic screening for POT needs and investigated psychosocial predictors for POT wish at a nuclear medicine department. METHODS: We extracted medical chart information about number of referrals and extent of follow-up contacts. During standard referral (November 2014 to October 2015), POT needs were identified by clinical staff only. In the screening-assisted referral period (November 2015 to October 2016), identification was supported by electronic screening for POT needs. Psychosocial predictors for POT wish were examined using logistic regression. RESULTS: We analysed data from 487 patients during standard referral (mean age 56.4 years; 60.2% female, 88.7% thyroid carcinoma or neuroendocrine tumours) of which 28 patients (5.7%) were referred for POT. Of 502 patients in the screening-assisted referral period (mean age 57.0 years; 55.8% female, 86.6% thyroid carcinoma or neuroendocrine tumours), 69 (13.7%) were referred for POT. Of these, 36 were identified by psycho-oncological (PO) screening and 33 by clinical staff. After PO-screening implementation, referrals increased by a factor of 2.4. The strongest predictor of POT wish was depressive mood (P < .001). During both referral periods, about 15% of patients visited the PO outpatient unit additionally to inpatient PO consultations. CONCLUSIONS: Our results provide evidence from a real-life setting that PO screening can foster POT referrals, reduce barriers to express the POT wish, and hence help to meet psychosocial needs of this specific patient group. Differences between patients' needs, wish, and POT uptake should be further investigated.

RESUMO

PURPOSE: Health behavior (HB) has been identified as contributing to breast cancer (BC) disease outcome. The present study was subjected to gain more in-depth insight into breast cancer survivors' (BCS) HB and its associations with patient quality of life (QOL) outcome. We investigated HB focusing on eating disturbances comparing the latter with a reference population sample (PS). MATERIALS AND METHODS: The research cohort included 303 BCS completing a comprehensive patient-reported-outcome assessment on HB (eating disturbances, exercise, substance use) and QOL. Data from an age- and education-matched reference PS (n = 303) on eating disturbances were included. RESULTS: Overall, 30% of BCS were overweight; 11.7% of BCS (2-11 years after diagnosis, mean = 5.2 years) reported eating disturbances compared with 5% of PS (P < .05). Approximately three-fourths of BCS indicated they exercise regularly, one-fourth smoke regularly, and 30% consume alcohol. Lower consumption of analgesics and tranquilizers, higher frequency of exercise, lower eating concern (EDE-Q), younger age, and lower body mass index were significant predictors for better physical QOL. Lower eating and shape concern were next to age-identified predictive for better psychological QOL. DISCUSSION: Obesity and eating disturbances are a considerable HB problem in women with a history of BC. Considering that HB is predictive for long-term QOL in BCS, routine counseling on HB should be integrated into survivorship care to increase patient education and contribute to behavioral changes.

RESUMO

BACKGROUND: Cancer survivorship is of increasing importance in post-treatment care. Sexual health (SH) and femininity can be crucial issues for women surviving cancer. We aimed to determine a more complete understanding of the contribution that a breast cancer (BC) diagnosis and its treatment exert on patients' follow-up SH. For this purpose, self-reported levels and predictors of SH in breast cancer survivors (BCS) were compared with those of women with no previous or current BC (WNBC). METHODS: BCS and WNBC underwent a comprehensive, cross-sectional patient-reported outcome (PRO) assessment. Validated PRO instruments were used to measure SH, body image, anxiety and depression and menopausal symptoms. Assessments were performed within the routine clinical setting. Instruments used were the Sexual Interest and Desire Inventory - Female, Sexual Activity Questionnaire, Body Image Scale, Hospital Anxiety and Depression Scale and the Menopause-Specific Quality of Life Questionnaire. RESULTS: One hundred five BCS (average time since diagnosis of 3 years) and 97 WNBC with a mean age of 49 years completed the assessment. SH was significantly worse in BCS compared to WNBC (p = 0.005; BCS SIDI-F mean = 24.9 vs. WNBC mean = 29.8). 68.8% of BCS and 58.8% of WNBC met criteria of a hypo-active sexual desire disorder. Higher depressive symptoms, higher age and lower partnership satisfaction were predictive for poorer SH in BCS. CONCLUSION: SH problems are apparent in BCS and differ significantly from those seen in the general population. Consequently, BC survivorship care should include interventions to ameliorate sexual dysfunction and provide help with depressive symptoms and partnership problems, which are associated with poor BCS SH.

RESUMO

OBJECTIVE: We investigated the psychosocial consequences of genetic counseling and testing (GCT) for hereditary breast and ovarian cancer (HBOC) at follow-up in a "real-life" sample of counselees at an Austrian tertiary care center. METHODS: The study cohort included counselees who had undergone genetic counseling for HBOC and completed a follow-up self-report questionnaire battery on psychosocial outcomes (quality of life, psychological distress, satisfaction with counseling and decisions). For comparison of distress, we recruited a reference sample of breast cancer survivors (BCS; n=665) who had not requested GCT in the same setting. RESULTS: Overall, counselees did not exhibit increased levels of anxiety and depression when compared to BCS. No specific follow-up deleterious psychosocial consequences were detected among the former group. Of the 137 counselees, 22.6% and 9.8% experienced clinically relevant levels of anxiety and depression, respectively, at an average follow-up time of 1.8years. However, both anxiety and depression significantly decreased with time and were alike between counselees with and without cancer diagnosis. Follow-up cancer worry seems to be significantly higher among counselees who had not undergone genetic testing or were undecided about it than among counselees who had been tested. CONCLUSION: Our results strongly support GCT as part of routine care for patients with HBOC. The risk factors of increased distress in specific subgroups of counselees, such as recent cancer diagnosis or uncertainty about testing, warrant further exploration and specific attention in clinical routines. Particularly, the psychological needs of undecided counselees warrant ongoing attention and potential follow-ups.

RESUMO

INTRODUCTION: The efficacy of adjuvant endocrine treatment with aromatase inhibitors (AIs), inhibiting the conversion of androgens to estrogen in adipose tissue, might depend on the overall volume of adipose tissue. However, little evidence is available regarding the pharmacokinetic behavior of AIs in women with obesity. The aim of this study was to investigate the interaction between body mass index (BMI) and anastrozole treatment as well as estrogenic activity. PATIENTS AND METHODS: A total of 216 postmenopausal patients with early-stage breast cancer who were receiving AI treatment with anastrozole constituted the final sample included in the analysis. During a regular 3-month after-care check-up, sociodemographic and clinical data and BMI were assessed. Blood samples were collected during routine blood testing. Measurement of AI plasma levels was performed by liquid chromatography-tandem mass spectrometry. Follicle stimulating hormone (FSH) and estradiol were measured within the routine blood examination. RESULTS: A median anastrozole plasma concentration of 34.7 ng/mL (mean, 37.4), with a large interindividual variability, was observed (SD, 15.1; range, 5.4-86.5). After age adjustment, it was found that anastrozole plasma concentrations significantly increased with BMI (r = 0.241; P = .001). Anastrozole serum concentrations in women with obesity (BMI ≥ 30) exceeded those of women with normal weight (BMI ≤ 25) by 25%. Women with excess weight had lower mean FSH levels, indicating higher estrogenic activity, compared with women with normal weight. CONCLUSION: This study indicates that BMI is a vital factor in anastrozole metabolism, as measured by anastrozole plasma concentration and FSH levels. Further research is mandatory to clarify results on the association of obesity and AI treatment efficacy to allow adapting AI treatment accordingly.

RESUMO

BACKGROUND: The European Organisation for Research and Treatment of Cancer (EORTC) Quality of Life Group is currently developing computerized adaptive testing measures for the Quality of Life Questionnaire Core-30 (QLQ-C30) scales. The work presented here describes the development of an EORTC item bank for emotional functioning (EF), which is one of the core domains of the QLQ-C30. METHODS: According to the EORTC guidelines on module development, the development of the EF item bank comprised four phases, of which the phases I-III are reported in the present paper. Phase I involved defining the theoretical framework for the EF item bank and a literature search. Phase II included pre-defined item selection steps and a multi-stage expert review process. In phase III, feedback from cancer patients from different countries was obtained. RESULTS: On the basis of literature search in phase I, a list of 1750 items was generated. These were reviewed and further developed in phase II with a focus on relevance, redundancy, clarity, and difficulty. The development and selection steps led to a preliminary list of 41 items. In phase III, patient interviews (N = 41; Austria, Denmark, Italy, and the UK) were conducted with the preliminary item list, resulting in some minor changes to item wording. The final list comprised 38 items. DISCUSSION: The phases I-III of the developmental process have resulted in an EF item list that was well accepted by patients in several countries. The items will be subjected to larger-scale field testing in order to establish their psychometric characteristics and their fit to an item response theory model.

RESUMO

BACKGROUND: Current studies on adherence to endocrine therapy in breast cancer patients suffer from methodological limitations due to a lack of well-validated methods for assessing adherence. There is no gold standard for measuring adherence. The aim of our study was to compare four different approaches for evaluating adherence to anastrozole therapy for breast cancer with regard to concordance between methods. METHODS: Outpatients with early breast cancer treated with anastrozole completed the multi-method assessment of adherence. We implemented a self-report scale (the Simplified Medication Adherence Questionnaire), physician- ratings, refill records and determination of anastrozole serum concentration. RESULTS: Comparison of the four approaches using Spearman rank correlation revealed poor concordance across all methods reflecting weak correlations of 0.2-0.4. Considering this data incomparability across methods, we still observed high adherence rates of 78%-98% across measures. CONCLUSION: Our findings contribute to the growing body of knowledge on the impact that methodological aspects exert on the results of adherence measurement in breast cancer patients receiving endocrine treatment. Our findings suggest that the development and validation of instruments specific to patients receiving endocrine agents is imperative in order to arrive at a more accurate assessment and to subsequently obtain more precise estimates of adherence rates in this patient population.

RESUMO

BACKGROUND: Diagnosis and treatment of ovarian cancer (OC) entail severe symptom burden and a significant loss of quality of life (QOL). Somatic and psychological impairments may persist well beyond active therapy. Although essential for optimal symptom management as well as for the interpretation of treatment outcomes, knowledge on the course of QOL-related issues is scarce. This study aimed at assessing the course of depressive symptoms, anxiety, fatigue and QOL in patients with OC over the course of chemotherapy until early after-care. METHODS: 23 patients were assessed longitudinally (eight time points) with regard to symptom burden (depression, anxiety, fatigue, and QOL) by means of patient-reported outcome instruments (HADS, MFI-20, EORTC QLQ-C30/-OV28) and clinician ratings (HAMA/D) at each chemotherapy cycle and at the first two aftercare visits. RESULTS: Statistically significant decrease over time was found for depressive symptoms and anxiety as well as for all fatigue scales. With regard to QOL, results indicated significant increase for 11 of 15 QOL scales, best for Social (effect size = 1.95; p < 0.001), Emotional (e.s. = 1.62; p < 0.001) and Physical Functioning (e.s. = 1.47; p < 0.001). Abdominal Symptoms (e.s. = 1.01; p = 0.009) decreased, Attitudes towards Disease and Treatment (e.s. = 1.80; p < 0.001) improved significantly over time. Analysis of Sexual Functioning was not possible due to a high percentage of missing responses (61.9%). CONCLUSIONS: The present study underlines the importance of longitudinal assessment of QOL in order to facilitate the identification of symptom burden in OC patients. We found that patients show high levels of fatigue, anxiety and depressive symptoms and severely impaired QOL post-surgery (i.e. at start of chemotherapy) but condition improves considerably throughout chemotherapy reaching nearly general population symptoms levels until aftercare.

RESUMO

Adjuvant endocrine treatment-related adverse effects have a strong impact on patients' quality of life and thereby limit therapy's risk benefit ratio resulting in morbidity and treatment discontinuation. Still, many AI adverse effects remain untreated given that they are unrecognized by conservative methods (e.g., proxy ratings). The ability of complementary patient-reported outcomes (PROs) to provide a more comprehensive assessment of side-effects is to be explored. A cross-sectional study sample of 280 postmenopausal, early stage breast cancer patients was subjected to a comprehensive PRO assessment (FACT-B/+ES) at their after-care appointment. Prevalence and severity of patient-reported physical side-effects and psychosocial burden related to adjuvant AI therapy were compared with prevalences derived from pivotal phase IV trials (ATAC 2005, BIG1-98 2005). Across all symptom categories, highest prevalence rates were found for joint pain (59.6%), hot flushes (52%), lost interest in sexual intercourse (51.4%), and lack of energy (40.3%). Overall, PROs resulted in significantly higher prevalence rates as compared to physician ratings for all symptoms published in pivotal clinical trials except vaginal bleeding and nausea. The treatment duration exerted no significant impact on symptom frequency (P > 0.05). Established prevalence rates of endocrine treatment-related toxicity seem to be underestimated. The incorporation of PRO data should be mandatory or at least highly recommended in clinical treatment planning to arrive at a more accurate assessment of a patient's actual symptom burden enabling improved individualized management of side-effects and mediating the preservation of treatment adherence.

RESUMO

The application of cytochrome P450 2D6 (CYP2D6) genotyping to allow a personalized treatment approach for breast cancer patients undergoing endocrine therapy has been repeatedly discussed. However, the actual clinical relevance of the CYP2D6 genotype in the endocrine treatment of breast cancer still remains to be elucidated. A major prerequisite for the successful and valid evaluation of the CYP2D6 genotype with regard to its pharmacokinetic and clinical relevance is the availability of a comprehensive, accurate and cost-effective CYP2D6 genotyping strategy. Herein we present a CYP2D6 genotyping assay employing polymerase chain reaction (PCR)-ion pair reversed-phase high-performance liquid chromatography-electrospray ionization time-of-flight mass spectrometry (ICEMS). The genotyping strategy involves the simultaneous amplification of nine variable regions within the CYP2D6 gene by a two-step PCR protocol and the direct analysis of the generated PCR amplicons by ICEMS. The nucleotide composition profiles generated by ICEMS enable the differentiation of 37 of the 80 reported CYP2D6 alleles. The assay was applied to type the CYP2D6 gene in 199 Austrian individuals including 106 breast cancer patients undergoing tamoxifen treatment. The developed method turned out to be a highly applicable, robust and cost-effective approach, enabling an economical CYP2D6 testing for large patient cohorts.

RESUMO

Tryptophan-degrading enzyme indoleamine 2,3-dioxygenase (IDO) represents an antimicrobial and antitumoral immune effector mechanism, but IDO also suppresses T-cell responses and thus can cause immune system failure. Therefore, IDO was proposed as an immunoescape mechanism of tumor cells. Compared to healthy controls, accelerated tryptophan degradation was observed in the blood of 20 patients with ovarian carcinoma as is reflected by an increased kynurenine to tryptophan ratio (kyn/trp) which allows an estimate of IDO activity. Higher FIGO stage but not tumor grading was associated with a higher rate of tryptophan degradation. Kyn/trp correlated strongly with concentrations of cytokine IL-6, of soluble interleukin-2 receptor-α and 75 kDa TNF-α receptor and of the macrophage marker neopterin (all p<0.001 or p<0.01) but not with TNF-α. Findings further supports the concept that increased IDO activity in ovarian cancer patients relates to immune activation pathways. Accordingly, accelerated tryptophan degradation appears to represent an immune escape mechanism. However IDO activity is not necessarily a spontaneous activity of ovarian cancer cells rather it is elicited by the activated immune system although an additional spontaneous activity of tumor cells cannot be ruled out.

RESUMO

There is substantial evidence that circulating estrogens promote the proliferation of breast cancer. Consequently, adjuvant hormonal treatment strategies targeting estrogen action have been established. Such hormonal therapies include selective estrogen receptor modulators, such as tamoxifen, which interfere at the estrogen receptors directly, or non-steroidal aromatase inhibitors, such as anastrozole and letrozole, which inhibit estrogen synthesis through blocking the aromatase, a key enzyme of estrogen production. Despite considerable therapeutic success, in several cases, the use of these drugs is limited by side effects that have been described to significantly impair the adherence of patients to endocrine treatment. However, objective data concerning patient adherence and its clinical relevance are limited. One promising approach to check patient-reported adherence is drug monitoring in human plasma. Therefore, a liquid chromatography-tandem mass spectrometry method to determine the plasma concentrations of tamoxifen, anastrozole, and letrozole has been developed and fully validated according to guidelines for clinical and forensic toxicology. The validation criteria evaluated were selectivity, linearity, accuracy and precision, limit of quantification, recovery and matrix effects, sample stability, and carryover. The six-point calibration curves showed linearity over the range of concentrations from 25 to 500 ng/ml for tamoxifen, 5 to 200 ng/ml for anastrozole, and 10 to 300 ng/ml for letrozole. The intra- and inter-day precision and accuracies were always better than 15%. The validated procedure was successfully applied to a clinical study (Patient-Reported Outcomes in Breast Cancer Patients undergoing Endocrine Therapy, PRO-BETh). A major aim of PRO-BETh study is the comprehensive evaluation of adherence to treatment in pre- and post-menopausal women with breast cancer. Plasma samples of 310 breast cancer patients undergoing anti-estrogen therapy were analyzed. Eight samples did not contain a quantifiable amount of drug, strongly indicating non-adherence of the corresponding patients to adjuvant breast cancer treatment. Furthermore, plasma concentrations at the lower end of the observed plasma level distribution might represent a hint but not a confirmation for non-adherence in terms of non-daily and irregular intake of the prescribed drug.

RESUMO

OBJECTIVE: In breast cancer patients the diagnosis, treatment and aftercare of the physical disease cause a large amount of psychosocial distress, which can have a variety of negative consequences on patients' physical and mental well-being. Although about one-third of the patients show heightened psychosocial distress that may require psychooncological interventions its detection in daily clinical routine is poor and referral to mental health professionals is insufficient. The aim of the study was to develop a short screening tool for the detection of need for psychooncological treatment (POT) in breast cancer patients. METHODS: Over a period of six months, 115 breast cancer outpatients attending the Department of Gynaecology at Innsbruck Medical University were consecutively included in the study. Logistic regression analysis and ROC analyses were used to identify the most predictive item set from a set of questionnaires (EORTC-QLQ-C30, HADS and Hornheide Screening Instrument) and other additional questions. RESULTS: Data from 105 breast cancer patients (mean age 58.8, SD 12.3) were available for analysis. A logistic regression equation containing the EORTC-QLQ-C30 scales Emotional Functioning and Role Functioning as well as the yes-no question after psychiatric/psychological/psychotherapeutic treatment at any point in lifetime showed highest predictive power with regard to need of POT (AUC=0.88; CI 95% 0.82-0.95). A pilot study (n=20) investigating applicability of a computerized version of this screening tool in oncological routine showed high acceptance and feasibility. CONCLUSION: The developed PO-screening tool showed high diagnostic accuracy regarding POT needs. The short assessment time and good usability of its computerized version allowed easy implementation in daily oncological routine.

RESUMO

Quality of life (QOL) has become a widely used outcome parameter in the evaluation of treatment modalities in clinical oncology research. By now, many of the practical problems associated with measuring QOL in clinical practice can be overcome by the use of computer-based assessment methods. QOL assessment in oncology is dominated by two measurement systems, the FACT scales and the EORTC QLQ-C30 with its modules. The amount of human resources required to implement routine data collection has been reduced significantly by advanced computer technology allowing data collection in busy clinical practice. Monitoring of QOL can contribute to oncologic care by facilitating detection of physical and psychological problems and tracking the course of disease and treatment over time. Furthermore, the integration of screening for psychosocial problems into QOL monitoring contributes to the identification of patients who are in need of psychooncologic interventions. Computer-based QOL monitoring does not replace the direct physician-patient communication but enables to identify specific impairments and symptoms including psychological problems. Beyond clinical practice, QOL data can be used for research purposes and may help health care planners to determine those patient services that should be maintained or ones that should be developed.

RESUMO

BACKGROUND AND OBJECTIVE: As long-term survivors of hematopoietic cell transplantation (HCT) become more numerous, studies addressing the issue of long-term follow-up are necessary. In this study, we report on the quality of life (QOL) of HCT-patients, who were alive at least at 5 yr after transplantation in comparison to an age- and sex-matched sample of healthy controls assessed in the same time-period and the same geographical region. DESIGN AND METHODS: The European Group of Research and Treatment of Cancer (EORTC)-QOL Questionnaire (EORTC-QLQ C30) was sent by post to 39 HCT-survivors. Thirty-four patients answered the questionnaire. Patients were compared with 68 healthy controls from the same geographical region. Patients and controls completed the EORTC in the same time period. RESULTS: Mann-Whitney U-tests identified significantly lower QOL on the dimensions of physical and social functioning and on the financial impact symptom scale. CONCLUSIONS: Patients who had survived their HCT for more than 5 yr did generally well in terms of global QOL. This is consistent with Kiss et al. (J Clin Oncol 2002;20:2334-2343), who found that chronic myeloid leukemia patients who were alive at least 10 yr after HCT report lower physical functioning in comparison to healthy controls. Problems in the areas of social functioning and financial difficulty can possibly be addressed by intensive rehabilitation processes integrating patients, family members and significant others. Interdisciplinary (medical, psychological and social) treatment of patients should not come to an end after the acute phase of the illness but should continue during check-ups following transplantation.

RESUMO

The aims of this study were to derive population-based reference values for the Functional Assessment of Cancer Therapy Scale-General (FACT-G) and to investigate the impact of sociodemographic variables (e.g. age, sex, health status) on these quality of life (QOL) scores, and to compare the normative QOL scores with those of various groups of cancer survivors. A random sample of 2 000 members of the Austrian public were sent questionnaires containing the FACT-G and questions relating to demographic data and health status. A total of 968 questionnaires were returned giving an overall response rate of 50.6% (females 48.3%, age 49.3 +/- 16.8). Subjects with higher education reported higher QOL values; divorced and widowed persons had significantly lower QOL scores. Higher age was also associated with lower QOL scores. After bone marrow transplantation, patients generally showed lower QOL scores than the age- and sex-matched population-based sample, whilst in breast cancer survivors there was reduced QOL regarding social well-being. Survivors of Hodgkin's disease were found to have higher functional and social well-being scores than those of the general population sample. Sociodemographic variables should always be taken into consideration when interpreting QOL scores. Furthermore, unless patient data are compared with normative values, phenomena such as adaptation and response shift might be missed or misinterpreted.

RESUMO

BACKGROUND: Although fatigue is a commonly reported symptom in cancer patients it is rarely investigated, especially in patients with ovarian carcinoma. The main focus of the current study was to assess fatigue in these patients and to investigate the impact of fatigue and other clinical and psychosocial variables on their quality of life (QOL). METHODS: Ninety-eight ovarian carcinoma survivors (average age of 57.4 +/- 12.5 years) were included in the study. All women had received cancer therapy but had not been treated for at least 6 months. The average time elapsed since first diagnosis was 5.7 +/- 5.5 years. Fatigue was measured with the Multidimensional Fatigue Inventory (MFI-20) and QOL was measured with the Functional Assessment of Cancer Therapy (FACT)-ovarian carcinoma part and the European Organization for Research and Treatment of Cancer Care Questionnaire, including the ovarian carcinoma module. RESULTS: Thirty-two of 98 ovarian carcinoma patients (32.7%, 95% confidence interval, 23.5-42.9%) reported MFI-20 General Fatigue scores >/= 12.0 and therefore could be characterized as suffering from fatigue. This group of patients had a significantly lower QOL, had higher scores of anxiety and depression, and perceived that they had less social support. In a multiple regression model, mental adjustment, social support, anxiety, and depression as well as fatigue were significant predictors of QOL (FACT-generic part total score) whereas clinical and sociodemographic variables were not. CONCLUSION: A remarkably high proportion of ovarian carcinoma survivors suffered from fatigue. Because this symptom is a key predictor of QOL, it should be given more attention in aftercare programs.
