Effect of sex on psychological distress and fatigue over time in a prospective cohort of cancer survivors.

BACKGROUND: Studies indicate a higher level of distress in women than men with cancer, but whether this difference is retained over time is unknown. We studied the frequency and level of distress and fatigue during time according to gender in a cohort of cancer survivors. PATIENTS AND METHODS: In this prospective study, cancer survivors were invited to undergo a psychological session immediately before the medical visit. Distress was assessed by the distress thermometer, and fatigue was assessed by the ESAS-r scale. Patients underwent follow-up visits to assess changes over time. RESULTS: A total of 305 patients and 568 visits were performed with a median follow-up of 15.8 months. At baseline, females, young age, and breast cancer patients had significantly higher distress. However, there was an increase in distress of 0.29 points every 6 months in males (95% CI, 0.09-0.50) versus no change in females (0.03 points, 95% CI, - 0.09-0.15; p-interaction = 0.01). The different behavior of cancer distress during time according to gender was more evident in subjects aged 68 or older due to increasing physical problems in men (p-interaction = 0.005). There was no change in fatigue with time according to sex. CONCLUSIONS: Women, younger age, and breast cancer patients had increased cancer distress at the initial visit. However, women tend to stabilize during follow-up, whereas men tend to worsen their distress, especially because of physical and emotional problems, suggesting different coping capabilities. TRIAL REGISTRATION: The study is registered at ClinicalTrials.gov NCT05122052. IMPLICATIONS FOR CANCER SURVIVORS: Interventions aimed at improving recognition of emotions related to disease experience in male cancer survivors appear necessary.

Patient- versus physician-reported outcomes in a low-dose tamoxifen trial in noninvasive breast cancer.

BACKGROUND: We recently conducted a de-escalation trial of low-dose tamoxifen 5 mg/day ("babytam", BT) or placebo given for 3 years in 500 women with noninvasive breast cancer. Women on babytam had a 52% reduction of recurrence (invasive breast cancer or DCIS) after 5 years. Since menopausal symptoms are major reasons for treatment withdrawal during tamoxifen preventive therapy, we compared and analyzed the patient-reported outcomes (PROs) with the physician-reported adverse events and studied their association with recurrence. METHODS: Menopausal symptoms recorded by physicians using the Common Terminology Criteria (CTCAEs) were compared with a patient self-reported validated questionnaire reviewed by a research nurse at baseline and every 6 months up to 36 months. Hot flashes (HF), the main outcome measure, were detected through a self-report 7-day diary for frequency and intensity. Treatment adherence and efficacy were assessed by the Kaplan-Meier curves and the Cox model. RESULTS: The number of HF events at 12, 24, and 36 months for PROs versus CTCAEs was 246 versus 12, 238 versus 8, and 210 versus 4, respectively. The majority of events were grade 1. There was no difference in PROs between babytam and placebo except for HF daily frequency, which increased by 1.5 events (95% CI, 1.1-1.8) on placebo to 2.1 on babytam (95% CI, 1.7-2.5, p = 0.05). The presence of HF at baseline was a favorable prognostic factor for recurrence and a predictive factor for response to babytam. Adherence was similar between babytam and placebo. CONCLUSIONS: The use of PROs is effective for identifying frequent mild grade menopausal symptoms which are underestimated by physicians but important prognostic and predictive factors. Research nurse can use these results as a tool to reassure patients about symptoms, improve adherence to treatment, and limit dropouts.

Pharmacokinetics, safety, and activity of trabectedin as first-line treatment in elderly patients who are affected by advanced sarcoma and are unfit to receive standard chemotherapy: A phase 2 study (TR1US study) from the Italian Sarcoma Group.

BACKGROUND: Although elderly patients (≥70 years) represent 30% of new diagnoses of soft tissue sarcoma (STS), they are underrepresented in clinical trials and are often unfit to receive standard anthracycline-based chemotherapy. Trabectedin is registered as a second-line treatment for advanced STS and is characterized by a favorable safety profile. METHODS: The aim of this single-arm, phase 2 study was to investigate trabectedin (scheduled dose, 1.3-1.5 mg/m2 ) as a first-line treatment in elderly patients with advanced stage STS who are inoperable and are unfit to receive standard anthracycline-based chemotherapy. The coprimary endpoints were progression-free survival at 3 months (PFS3) and the rate of clinically limiting toxicities (CLTs). We also conducted an ancillary study on pharmacokinetics. RESULTS: Twenty-four patients (12 men and 12 women) with a median age of 79 years (interquartile range [IQR], 74-83 years) were enrolled. The histological subtype was leiomyosarcoma in 46%, liposarcoma in 33%, and other histotypes in 21%. The median number of trabectedin courses was 4 (IQR, 3-6), with 7 patients (29%) receiving ≥6 cycles. Eight patients (33%) required dose reductions. The most frequent grade 3/4 adverse events were neutropenia in 9 patients (38%), fatigue in 5 patients (21%), and aminotransferase elevation in 5 patients (21%). PFS3, median PFS, and overall survival were 71% (80% CI, 57%-81%), 4 months, and 12 months, respectively. Ten patients (42% [80% CI, 28%-57%]) experienced CLTs. Trabectedin Cmax , half-life, clearance, and distribution volume were 1.28 ng/mL (standard deviation [SD], 0.58 ng/mL), 26.70 hours (SD, 9.09 hours), 39.98 L/h/m2 (SD, 14.08 L/h/m2 ), and 1460 L/m2 (SD, 561 L/m2 ), respectively. CONCLUSION: Trabectedin can be administered safely to elderly patients with STS who are unfit to receive anthracyclines. Pharmacokinetics in the elderly population was superimposable to historical data.

HCV elimination plan leads to significant benefits in managing liver-related diseases and hospital interventions: a regional simulation.

OBJECTIVES: This article presents a 3-year budget impact simulation on the effects of a chronic Hepatitis C (HCV) eradication plan in real-life costs incurred by the Regional Health Service. METHODS: The Liguria Region network performed a prospective 3-year (2017-2019) timeframe horizon trends simulation analysis focusing on management interventions and costs. It involved all the eight prescribing centers in the region, starting from retrospective historical performance data and assuming the impact of sustained viral response rates for patients treated for HCV. Data on hospital admissions, medical visits, number of patients, and deaths were collected through the healthcare database. RESULTS: At the beginning of 2017, 2,940 patients were eligible for HCV treatment with direct-acting antivirals. Assuming to treat this entire population with a success rate of 90%, the events related to liver complications in the horizon would decrease to 5,538 cumulatively (-35%), with a 27% reduction of direct costs, showing a global savings of 24,779.024 Euros. CONCLUSION: Treating the entire eligible HCV population would lead to significant benefits and savings in managing liver-related diseases and their direct costs, opening opportunities to re-think new settings for the future organization of liver disease management in the regional health system.

Worry and risk perception of breast cancer in a prevention trial of low dose tamoxifen in midlife postmenopausal hormone users.

OBJECTIVE: There is increasing interest in combining postmenopausal hormone therapy (HT) and SERMs in midlife women. We previously showed that refusal to participate in a prevention trial of low dose tamoxifen in HT users was associated with higher worry about breast cancer. Given this counterintuitive finding, we studied which factors influenced worry and risk perception of breast cancer. METHODS: We assessed the relationships of breast cancer worry and risk perception with age, age at menopause, Gail risk, education, adherence to mammographic screening, BMI, smoking, physical activity, alcohol use, anxiety and depression in 457 midlife HT users who were eligible to participate in the trial. RESULTS: Women with menopause <48 years were more worried about breast cancer than women with menopause >52 years (OR = 5.0, 95% CI, 1.2-21.1). Worry was also associated with high absolute risk perception and former smoking. Factors associated with higher risk perception were age>60 years, at-risk life style, worry about breast cancer and depression. CONCLUSIONS: The inverse association between early menopause and worry about breast cancer is in contrast with the known protective effect of early menopause on breast cancer risk and seems to reflect a feeling of aging and disease vulnerability. Our findings indicate that worry about cancer has an affective construct which is independent of breast cancer biology but is engaged in health decision making. Increasing breast cancer risk awareness in subjects high in worry without a plan of emotional coping may therefore be counterproductive because of avoidant attitudes.

Association of Biomarkers with Serious Cardiac Adverse Events during Abiraterone Acetate Treatment in Castration Resistant Prostate Cancer.

BACKGROUND: Abiraterone acetate is an effective drug for castration-resistant prostate cancer, but cardiac serious adverse events (SAEs) may occur. We studied their association with N-terminal pro-brain natriuretic peptide (NT-proBNP) and troponin T (TnT) during abiraterone therapy. PATIENTS AND METHODS: In a single institution, 17 patients were treated with abiraterone acetate 1 g daily with concomitant prednisone and then switched to dexametasone plus canrenone. Blood samples for PSA, NT-proBNP, and TnT were obtained at baseline and after 1, 3, and 6 months. RESULTS: Five patients (29.4%) experienced G3 to 4 cardiac SAEs after a median of 13 weeks (range, 9-32), including pulmonary edema, heart failure, acute coronary syndrome, sinus bradycardia with syncope, and pulmonary edema. At baseline, 4 weeks, and 3 months, median NT-proBNP and TnT levels were higher in patients with subsequent cardiac SAEs (P= .03 and P= .04 for NT-proBNP and TnT at 3 months, respectively). After switching to dexametasone and introducing canrenone, no additional cardiac SAEs were noted. Overall response rate was 67%. CONCLUSIONS: Our study suggests a higher than expected risk of cardiac SAEs during abiraterone treatment which may well be due to the small sample size and the unrestricted entry criteria. However, baseline and frequent NT-proBNP and TnT monitoring predicted a higher risk for cardiac SAE. Larger studies should confirm our findings.

Cost of HAART in Italy: multicentric evaluation and determinants from a large HIV outpatient cohort.

BACKGROUND: As HIV infection turned into a chronic treatable disease, now ranking as one of the most costly in medicine, long-term sustainability of highly active antiretroviral treatment (HAART) expenses became a major issue, especially in countries with universal access to care. Identification of determinants of higher HAART costs may therefore help in controlling costs of care, while keeping high levels of retention in care and viral suppression. METHODS: With this aim, we enrolled a large multicentric sample of consecutive unselected human immunodeficiency virus (HIV) patients followed at five sites of care in Italy, and evaluated annual individual HAART costs in relation to a number of sociodemographic, clinical, and laboratory variables. RESULTS: We enrolled 2,044 patients, including 1,902 on HAART. Mean HAART costs were €9,377±€3,501 (range 782-29,852) per year, with remarkable site-based differences, possibly related to the different composition of local assisted populations. Percentages of patients on viral suppression were homogeneously high across all study sites. The factors identified by cross-validation were line of HAART, diagnosis of acquired immune deficiency syndrome, current CD4 T-cell count, and detectable HIV viremia >50 copies/mL. In the final multivariable model, HAART costs were independently directly associated with more advanced HAART line (P<0.001) and inversely correlated with current CD4 T-cell count (P=0.024). Site of care held independent prediction of higher costs, with marked control of expenses at sites 2 (P=0.001) and 5 (P<0.001). CONCLUSION: Higher costs of HAART were strongly associated with previous treatment failures, detectable HIV viremia, and lower CD4 T-cell count at the time of evaluation, with no correlation at all with sex, age, hepatitis C virus coinfection, and nadir CD4 T-cell counts. Newer drugs, which are typically those associated with high prices, at the time of the analysis were still prevalently prescribed to rescue and maintain viral suppression in patients with more complex treatment history. Further analyses of the contribution of the single drug/regimen to the estimated cost are warranted.

An observational study of nasal cavity toxicity in cancer patients treated with bevacizumab.

BACKGROUND: The nasal cavity is a vulnerable zone which may be damaged by vascular disorders. We systematically assessed the frequency and severity of nasal cavity alterations during bevacizumab treatment, to determine its clinical relevance and factors contributing to its onset. PATIENTS AND METHODS: We conducted a hospital-based cohort study in 47 consecutive patients with advanced cancers who were on treatment with chemotherapy and bevacizumab at different doses. All patients underwent otolaryngology (ENT) examination at the time of study initiation. RESULTS: The mean number of cycles at first ENT examination was 16 (standard deviation = 14). A total of 45 patients (96%) showed nose mucosal lesions, of whom 30% had erosions and 62% had grade 1 - 2 epistaxis. One patient had septal perforation. Grades 1 - 4 sinus disorders were noted in 60%. There was a significant trend to a higher risk of grade ≥ 2 nasal events for bevacizumab doses > 7.5 mg/kg, concomitant taxane use and digital nasal self-manipulation. CONCLUSIONS: We found a high incidence of nasal cavity lesions in patients receiving bevacizumab, with evidence for a dose-related effect. Most cases were low grade and manageable without drug interruption, but severe toxicity may rarely occur. Oncologists should be aware of this unusual event.

SWS: accessing SRS sites contents through Web Services.

BACKGROUND: Web Services and Workflow Management Systems can support creation and deployment of network systems, able to automate data analysis and retrieval processes in biomedical research. Web Services have been implemented at bioinformatics centres and workflow systems have been proposed for biological data analysis. New databanks are often developed by taking into account these technologies, but many existing databases do not allow a programmatic access. Only a fraction of available databanks can thus be queried through programmatic interfaces. SRS is a well know indexing and search engine for biomedical databanks offering public access to many databanks and analysis tools. Unfortunately, these data are not easily and efficiently accessible through Web Services. RESULTS: We have developed 'SRS by WS' (SWS), a tool that makes information available in SRS sites accessible through Web Services. Information on known sites is maintained in a database, srsdb. SWS consists in a suite of WS that can query both srsdb, for information on sites and databases, and SRS sites. SWS returns results in a text-only format and can be accessed through a WSDL compliant client. SWS enables interoperability between workflow systems and SRS implementations, by also managing access to alternative sites, in order to cope with network and maintenance problems, and selecting the most up-to-date among available systems. CONCLUSIONS: Development and implementation of Web Services, allowing to make a programmatic access to an exhaustive set of biomedical databases can significantly improve automation of in-silico analysis. SWS supports this activity by making biological databanks that are managed in public SRS sites available through a programmatic interface.

Biowep: a workflow enactment portal for bioinformatics applications.

BACKGROUND: The huge amount of biological information, its distribution over the Internet and the heterogeneity of available software tools makes the adoption of new data integration and analysis network tools a necessity in bioinformatics. ICT standards and tools, like Web Services and Workflow Management Systems (WMS), can support the creation and deployment of such systems. Many Web Services are already available and some WMS have been proposed. They assume that researchers know which bioinformatics resources can be reached through a programmatic interface and that they are skilled in programming and building workflows. Therefore, they are not viable to the majority of unskilled researchers. A portal enabling these to take profit from new technologies is still missing. RESULTS: We designed biowep, a web based client application that allows for the selection and execution of a set of predefined workflows. The system is available on-line. Biowep architecture includes a Workflow Manager, a User Interface and a Workflow Executor. The task of the Workflow Manager is the creation and annotation of workflows. These can be created by using either the Taverna Workbench or BioWMS. Enactment of workflows is carried out by FreeFluo for Taverna workflows and by BioAgent/Hermes, a mobile agent-based middleware, for BioWMS ones. Main workflows' processing steps are annotated on the basis of their input and output, elaboration type and application domain by using a classification of bioinformatics data and tasks. The interface supports users authentication and profiling. Workflows can be selected on the basis of users' profiles and can be searched through their annotations. Results can be saved. CONCLUSION: We developed a web system that support the selection and execution of predefined workflows, thus simplifying access for all researchers. The implementation of Web Services allowing specialized software to interact with an exhaustive set of biomedical databases and analysis software and the creation of effective workflows can significantly improve automation of in-silico analysis. Biowep is available for interested researchers as a reference portal. They are invited to submit their workflows to the workflow repository. Biowep is further being developed in the sphere of the Laboratory of Interdisciplinary Technologies in Bioinformatics - LITBIO.

Web services and workflow management for biological resources.

BACKGROUND: The completion of the Human Genome Project has resulted in large quantities of biological data which are proving difficult to manage and integrate effectively. There is a need for a system that is able to automate accesses to remote sites and to "understand" the information that it is managing in order to link data properly. Workflow management systems combined with Web Services are promising Information and Communication Technologies (ICT) tools. Some have already been proposed and are being increasingly applied to the biomedical domain, especially as many biology-related Web Services are now becoming available. Information on biological resources and on genomic sequences mutations are two examples of very specialized datasets that are useful for specific research domains. RESULTS: The architecture of a system that is able to access and execute predefined workflows is presented in this paper. Web Services allowing access to the IARC TP53 Mutation Database and CABRI catalogues of biological resources have been implemented and are available on-line. Example workflows which retrieve data from these Web Services have also been created and are available on-line. CONCLUSION: We present a general architecture and some building blocks for the implementation of a system that is able to remotely execute workflows of biomedical interest and show how this approach can effectively produce useful outputs. The further development and implementation of Web Services allowing access to an exhaustive set of biomedical databases and the creation of effective and useful workflows will improve the automation of in-silico analysis.
