Increased FOXJ1 protein expression is associated with improved overall survival in high-grade serous ovarian carcinoma: an Ovarian Tumor Tissue Analysis Consortium Study.

BACKGROUND: Recently, we showed a >60% difference in 5-year survival for patients with tubo-ovarian high-grade serous carcinoma (HGSC) when stratified by a 101-gene mRNA expression prognostic signature. Given the varied patient outcomes, this study aimed to translate prognostic mRNA markers into protein expression assays by immunohistochemistry and validate their survival association in HGSC. METHODS: Two prognostic genes, FOXJ1 and GMNN, were selected based on high-quality antibodies, correlation with protein expression and variation in immunohistochemical scores in a preliminary cohort (n = 134 and n = 80, respectively). Six thousand four hundred and thirty-four (FOXJ1) and 5470 (GMNN) formalin-fixed, paraffin-embedded ovarian neoplasms (4634 and 4185 HGSC, respectively) represented on tissue microarrays from the Ovarian Tumor Tissue Analysis consortium underwent immunohistochemical staining and scoring, then univariate and multivariate survival analysis. RESULTS: Consistent with mRNA, FOXJ1 protein expression exhibited a linear, increasing association with improved overall survival in HGSC patients. Women with >50% expression had the most favourable outcomes (HR = 0.78, 95% CI 0.67-0.91, p < 0.0001). GMNN protein expression was not significantly associated with overall HSGC patient survival. However, HGSCs with >35% GMNN expression showed a trend for better outcomes, though this was not significant. CONCLUSION: We provide foundational evidence for the prognostic value of FOXJ1 in HGSC, validating the prior mRNA-based prognostic association by immunohistochemistry.

Validated biomarker assays confirm that ARID1A loss is confounded with MMR deficiency, CD8+ TIL infiltration, and provides no independent prognostic value in endometriosis-associated ovarian carcinomas.

ARID1A (BAF250a) is a component of the SWI/SNF chromatin modifying complex, plays an important tumour suppressor role, and is considered prognostic in several malignancies. However, in ovarian carcinomas there are contradictory reports on its relationship to outcome, immune response, and correlation with clinicopathological features. We assembled a series of 1623 endometriosis-associated ovarian carcinomas, including 1078 endometrioid (ENOC) and 545 clear cell (CCOC) ovarian carcinomas, through combining resources of the Ovarian Tumor Tissue Analysis (OTTA) Consortium, the Canadian Ovarian Unified Experimental Resource (COEUR), local, and collaborative networks. Validated immunohistochemical surrogate assays for ARID1A mutations were applied to all samples. We investigated associations between ARID1A loss/mutation, clinical features, outcome, CD8+ tumour-infiltrating lymphocytes (CD8+ TILs), and DNA mismatch repair deficiency (MMRd). ARID1A loss was observed in 42% of CCOCs and 25% of ENOCs. We found no associations between ARID1A loss and outcomes, stage, age, or CD8+ TIL status in CCOC. Similarly, we found no association with outcome or stage in endometrioid cases. In ENOC, ARID1A loss was more prevalent in younger patients (p = 0.012) and was associated with MMRd (p < 0.001) and the presence of CD8+ TILs (p = 0.008). Consistent with MMRd being causative of ARID1A mutations, in a subset of ENOCs we also observed an association with ARID1A loss-of-function mutation as a result of small indels (p = 0.035, versus single nucleotide variants). In ENOC, the association with ARID1A loss, CD8+ TILs, and age appears confounded by MMRd status. Although this observation does not explicitly rule out a role for ARID1A influence on CD8+ TIL infiltration in ENOC, given current knowledge regarding MMRd, it seems more likely that effects are dominated by the hypermutation phenotype. This large dataset with consistently applied biomarker assessment now provides a benchmark for the prevalence of ARID1A loss-of-function mutations in endometriosis-associated ovarian cancers and brings clarity to the prognostic significance. © 2021 The Pathological Society of Great Britain and Ireland.

The use of intraperitoneal chemotherapy for advanced ovarian cancer - The experience of a tertiary referral centre.

BACKGROUND: Platinum-based chemotherapy is the backbone of the medical management of ovarian cancer. The dose, route and timing of treatment are ongoing areas of debate. Intraperitoneal (IP) chemotherapy is an alternative delivery method treatment to the conventional intravenous (IV) route for patients with epithelial ovarian cancer, with efficacy supported by Level 1 evidence. AIMS: To compare the outcomes and feasibility of IP to IV delivery of platinum-based chemotherapy in patients with advanced epithelial ovarian cancer. MATERIALS AND METHODS: In a single institution, patients receiving adjuvant chemotherapy (IP and IV) for Stages III and IV epithelial ovarian cancer over the period January 2006-December 2018 were identified through a prospectively maintained database. All patients with an IP port inserted were included. A control group of patients treated with IV chemotherapy was created using criteria identified during the study and in the randomised trials that tested IP chemotherapy. Assessments were made for relapse-free survival (RFS) and overall survival (OS) for each cohort. RESULTS: A total of 639 patients received adjuvant chemotherapy (73 IP and 566 IV) during the study period. Both the IP group and matched IV control group (65 patients) had a median RFS of 26 months. The median OS in the IP group was 63.9 months, and in the IV group was 57.2 months. At ten years, a significantly higher proportion of patients were alive in the IP group cohort (16% vs 3%, relative risk 5.5, 95% CI 1.29-24, P = 0.012). IP chemotherapy was well tolerated by our cohort. In the IP group, 73% had four or more IP cycles and 99% received six or more cycles of chemotherapy. CONCLUSIONS: Our cohort had a high rate of completion of IP chemotherapy with excellent rates of completion of six cycles of any treatment. The RFS and OS in the IP chemotherapy group were comparable to each other and reflected those in the published literature. A significantly higher proportion of patients in the IP cohort were alive at ten years than in the IV cohort.

Mainstream genetic testing for high-grade ovarian, tubal and peritoneal cancers: A tertiary referral centre experience.

BACKGROUND: Fifteen percent of ovarian, tubal, and peritoneal (OTP) invasive epithelial cancers are linked to an underlying heritable pathogenic variant (PV) in the BRCA1/2 cancer susceptibility genes. Identifying a PV has management implications for an affected individual and relatives. Cancer team-facilitated genetic testing (mainstreaming) aims to provide equitable systematic access to genetic testing for appropriate patients. AIM: To evaluate a multi-disciplinary team (MDT)-led mainstream germline genetic testing program for OTP cancer at a tertiary referral centre. MATERIALS AND METHODS: We conducted a retrospective review of our MDT-led mainstream genetic testing program initiated in June 2017. We included all patients diagnosed with OTP cancer registered with the hospital gynaecological oncology MDT from program initiation to December 2020. Patients were considered eligible for testing if they were diagnosed with a high-grade epithelial OTP AND ≤70 years, OR if >70 with a first/second degree relative with breast and/or ovarian cancer OR Jewish ancestry. RESULTS: Of 205 women diagnosed with high-grade epithelial OTP cancer, 140 were eligible for mainstreaming. Eight-five percent were mainstreamed, with the gynae-oncologists facilitating 64.5% of tests. The overall PV detection rate in BRCA1/2 was 10.1% (BRCA1 n = 9, BRCA2 n = 3). The median turnaround time (TAT) was 44.5 days (range 16-118). All women with PV were referred to the Familial Cancer Service for further assessment and five (of six eligible; 83%) were subsequently treated with polyadenosine diphosphate ribose polymerase inhibitors. Cascade testing was undertaken in 75% of families with a mean of three relatives tested per proband. CONCLUSION: Mainstreamed genetic testing is feasible, with an acceptable TAT, ensuring adequate opportunity to inform treatment decisions. Tumour testing and inclusion of moderate-risk cancer predisposition genes in mainstreaming represent potential pathways that will require further exploration.

Policies are Needed to Increase the Reach and Impact of Evidence-Based Parenting Supports: A Call for a Population-Based Approach to Supporting Parents, Children, and Families.

Parents can be essential change-agents in their children's lives. To support parents in their parenting role, a range of programs have been developed and evaluated. In this paper, we provide an overview of the evidence for the effectiveness of parenting interventions for parents and children across a range of outcomes, including child and adolescent mental and physical health, child and adolescent competencies and academic outcomes, parental skills and competencies, parental wellbeing and mental health, and prevention of child maltreatment and family violence. Although there is extensive research showing the effectiveness of evidence-based parenting programs, these are not yet widely available at a population level and many parents are unable to access support. We outline how to achieve increased reach of evidence-based parenting supports, highlighting the policy imperative to adequately support the use of these supports as a way to address high priority mental health, physical health, and social problems.

Feasibility of Microlearning for Improving the Self-Efficacy of Cancer Patients Managing Side Effects of Chemotherapy.

Lung cancer patients have a high symptom burden that negatively affects their quality of life. Increasing patient self-efficacy to deal with treatment side effects can ameliorate their symptom burden. Education programs can help enhance patient self-efficacy by giving patients more control over their condition through increased disease literacy. This study aimed to evaluate the feasibility of microlearning for delivering lung cancer patients' information on side effects of chemotherapy. Secondary objectives of the program are to understand the acceptability of microlearning for delivery this type of education to lung cancer patients and the potential impact of microlearning on patient self-efficacy, knowledge and confidence managing side effects of chemotherapy. A mixed-methods prepost test (or quasi-experimental) study design was used to better enable patients to identify and manage the side effects of their condition and chemotherapy. Participants were patients diagnosed with stage II to stage IV lung cancer, who had a life expectancy of greater than 3 months and were aged 18 years or older. Multiple validated scales were used to assess patient self-efficacy pre- and post-intervention. The online program was evaluated using quantitative data of completion rates extracted from the online platform. Semi-structured interviews were used to explore the impact of the online program on perceived self-efficacy and quality of life. Twenty-three participants agreed to participate in the study and five agreed to complete a semi-structured interview. Participants found the content comprehensive, relevant and engaging. The program improved perceived disease literacy and helped participants develop coping strategies to manage side effects. Participants also found the platform easy to use and navigate. Additional courses and features were requested. Patients with a diagnosis of cancer receive a large amount of information about the side effects of chemotherapy and how to manage them. This information is often provided soon after diagnosis or upon commencement of therapy, which can be overwhelming for some patients. Microlearning, a method of online learning that spaces distributing of content over several weeks, may be a useful tool for supporting delivering of health information to this group of patients.

Impact of the EndoPredict genomic assay on treatment decisions for oestrogen receptor-positive early breast cancer patients: benefits of physician selective testing.

PURPOSE: Genomic tests improve accuracy of risk prediction for early breast cancers but these are expensive. This study evaluated the clinical utility of EndoPredict®, in terms of impact on adjuvant therapy recommendations and identification of parameters to guide selective application. METHODS: Patients with ER-positive, HER2-negative, and early-stage invasive breast cancer were tested with EndoPredict®. Two cohorts were recruited: one consecutively and another at clinical team discretion. Systemic treatment recommendations were recorded before and after EndoPredict® results were revealed to the multidisciplinary team. RESULTS: 233 patients were recruited across five sites: 123 consecutive and 110 at clinical team discretion. In the consecutive cohort 50.6% (62/123) cases were classified high risk of recurrence by EndoPredict®, compared with 62.7% (69/110) in the selective cohort. A change in treatment recommendation was significantly more likely (p < 0.0001) in the selective cohort (43/110, 39.1%) compared to the consecutive group (11/123, 8.9%). The strongest driver of selective recruitment was intermediate grade histology, whilst logistic regression modelling demonstrated that nodal status (p < 0.001), proliferative rate (p = 0.001), and progesterone receptor positivity (p < 0.001) were the strongest discriminators of risk. CONCLUSION: Whilst molecular risk can be predicted by traditional variables in a high proportion of cases, EndoPredict® had a greater impact on treatment decisions in those cases selected for testing at team discretion. This is indicative of the robust ability of the clinical team to identify cases most likely to benefit from testing, underscoring the value of genomic tests in the oncologists' tool kit.

Whole-genome characterization of chemoresistant ovarian cancer.

Patients with high-grade serous ovarian cancer (HGSC) have experienced little improvement in overall survival, and standard treatment has not advanced beyond platinum-based combination chemotherapy, during the past 30 years. To understand the drivers of clinical phenotypes better, here we use whole-genome sequencing of tumour and germline DNA samples from 92 patients with primary refractory, resistant, sensitive and matched acquired resistant disease. We show that gene breakage commonly inactivates the tumour suppressors RB1, NF1, RAD51B and PTEN in HGSC, and contributes to acquired chemotherapy resistance. CCNE1 amplification was common in primary resistant and refractory disease. We observed several molecular events associated with acquired resistance, including multiple independent reversions of germline BRCA1 or BRCA2 mutations in individual patients, loss of BRCA1 promoter methylation, an alteration in molecular subtype, and recurrent promoter fusion associated with overexpression of the drug efflux pump MDR1.

Improving Cancer MDT performance in Western Sydney - three years' experience.

BACKGROUND: While multidisciplinary teams (MDTs) are now considered an essential part of cancer care decision-making, how they perform varies widely. The authors hypothesised that a comprehensive, multipronged improvement program, and associated annual member survey, could strengthen MDT performance across a whole cancer service. METHODS: The study comprised the introduction of a structured program, the Tumour Program Strengthening Initiative (TPSI) linked with an annual survey of member's perceptions of their performance. Three iterations of the survey have been completed (2017, 2018 and 2019). Generalised estimating equations (GEEs) were used to test for a difference in the proportion of positive survey responses between 2017 and 2019 adjusted for team clustering. RESULTS: Twelve teams participated in TPSI. One hundred twenty-nine, 118 and 146 members completed the survey in 2017, 2018 and 2019, respectively. Of the 17 questions that were asked in all three years, nine showed significant improvement and, of these, five were highly significant. Documenting consensus, developing Terms of Reference (TORs), establishing referral criteria and referring to clinical practice guidelines showed most improvement. Questions related to patient considerations, professional development and quality improvement (QI) activities showed no significant change. CONCLUSIONS: TPSI resulted in sustained and significant improvement. The MDT survey not only allowed MDT members to identify their strengths and weaknesses but also provided insights for management to flag priority areas for further support. Overall program improvement reflected the strengthening of the weakest teams as well as further improvement in highly performing MDTs. Importantly, the initiative has the potential to achieve behaviour change amongst clinicians.

Developing an Intranet-Based Lymphedema Dashboard for Breast Cancer Multidisciplinary Teams: Design Research Study.

BACKGROUND: A large quantity of data is collected during the delivery of cancer care. However, once collected, these data are difficult for health professionals to access to support clinical decision making and performance review. There is a need for innovative tools that make clinical data more accessible to support health professionals in these activities. One approach for providing health professionals with access to clinical data is to create the infrastructure and interface for a clinical dashboard to make data accessible in a timely and relevant manner. OBJECTIVE: This study aimed to develop and evaluate 2 prototype dashboards for displaying data on the identification and management of lymphedema. METHODS: The study used a co-design framework to develop 2 prototype dashboards for use by health professionals delivering breast cancer care. The key feature of these dashboards was an approach for visualizing lymphedema patient cohort and individual patient data. This project began with 2 focus group sessions conducted with members of a breast cancer multidisciplinary team (n=33) and a breast cancer consumer (n=1) to establish clinically relevant and appropriate data for presentation and the visualization requirements for a dashboard. A series of fortnightly meetings over 6 months with an Advisory Committee (n=10) occurred to inform and refine the development of a static mock-up dashboard. This mock-up was then presented to representatives of the multidisciplinary team (n=3) to get preliminary feedback about the design and use of such dashboards. Feedback from these presentations was reviewed and used to inform the development of the interactive prototypes. A structured evaluation was conducted on the prototypes, using Think Aloud Protocol and semistructured interviews with representatives of the multidisciplinary team (n=5). RESULTS: Lymphedema was selected as a clinically relevant area for the prototype dashboards. A qualitative evaluation is reported for 5 health professionals. These participants were selected from 3 specialties: surgery (n=1), radiation oncology (n=2), and occupational therapy (n=2). Participants were able to complete the majority of tasks on the dashboard. Semistructured interview themes were categorized into engagement or enthusiasm for the dashboard, user experience, and data quality and completeness. CONCLUSIONS: Findings from this study constitute the first report of a co-design process for creating a lymphedema dashboard for breast cancer health professionals. Health professionals are interested in the use of data visualization tools to make routinely collected clinical data more accessible. To be used effectively, dashboards need to be reliable and sourced from accurate and comprehensive data sets. While the co-design process used to develop the visualization tool proved effective for designing an individual patient dashboard, the complexity and accessibility of the data required for a cohort dashboard remained a challenge.

Pamiparib in combination with tislelizumab in patients with advanced solid tumours: results from the dose-escalation stage of a multicentre, open-label, phase 1a/b trial.

BACKGROUND: Rationale exists for combined treatment with immune checkpoint inhibitors and poly (ADP-ribose) polymerase (PARP) inhibitors in a variety of solid tumours. This study aimed to investigate the safety and antitumour effects of pamiparib, an oral PARP 1/2 inhibitor, combined with tislelizumab, a humanised anti-PD-1 monoclonal antibody, in patients with advanced solid tumours and to determine the optimum doses for further evaluation. METHODS: We did a multicentre, open-label, phase 1a/b study at five academic sites or community oncology centres in Australia. We recruited adults (aged ≥18 years) with advanced solid tumours who had received one or more previous lines of therapy, with an Eastern Cooperative Oncology Group performance score of 1 or less, and a life expectancy of 12 weeks or more. Patients were enrolled into one of five dose-escalation cohorts, with dose-escalation done in a 3 + 3 design. Cohorts 1-3 received intravenous tislelizumab 2 mg/kg every 3 weeks plus 20, 40, or 60 mg oral pamiparib twice daily, respectively; cohorts 4 and 5 received 200 mg intravenous tislelizumab every 3 weeks plus 40 or 60 mg oral pamiparib twice daily, respectively. The primary endpoints of the phase 1a dose-escalation part of the study were safety and tolerability, including the occurrence of dose-limiting toxicities and determination of the maximum tolerated dose and recommended phase 2 dose. All primary endpoints were analysed in the safety analysis set, which included all patients who received at least one dose of tislelizumab or pamiparib, with the exception of the occurrence of dose-limiting toxicities, which was analysed in the dose-limiting toxicity analysis set, which included all patients who received at least 90% of the first scheduled tislelizumab dose and at least 75% of scheduled pamiparib doses, or who had a dose-limiting toxicity event during cycle 1. Reported here are results of the phase 1a dose-escalation stage of the trial. This trial is registered with ClinicalTrials.gov, number NCT02660034, and is ongoing. FINDINGS: Between Jan 22, 2016, and May 16, 2017, we enrolled 49 patients (median age 63 years [IQR 55-67]), all of whom received at least one dose of pamiparib or tiselzumab. Four patients had dose-limiting toxicities (intractable grade 2 nausea [n=1] and grade 3 rash [n=1] in cohort 4, and grade 2 nausea and vomiting [n=1] and grade 4 immune-mediated hepatitis [n=1] in cohort 5). The recommended phase 2 dose was tislelizumab 200 mg every 3 weeks plus pamiparib 40 mg twice daily (the dose given in cohort 4). The most common treatment-emergent adverse events were nausea (in 31 [63%] of 49 patients), fatigue (26 [53%]), diarrhoea (17 [35%]), and vomiting (15 [31%]). 23 (47%) of 49 patients had immune-related adverse events, of whom nine (39%) had asymptomatic grade 3-4 hepatic immune-related adverse events, which were reversible with corticosteroid treatment. The most common adverse event of grade 3 or worse severity was anaemia (in six [12%] patients) and no grade 5 adverse events were reported. Hepatitis or autoimmune hepatitis was the only serious adverse event to occur in two or more patients (in four [8%] patients). At a median follow-up of 8·3 months (IQR 4·8-12·8), ten (20%) of 49 patients achieved an objective response according to Response Evaluation Criteria in Solid Tumours (RECIST) version 1.1, including two complete responses and eight partial responses. INTERPRETATION: Pamiparib with tislelizumab was generally well tolerated and associated with antitumour responses and clinical benefit in patients with advanced solid tumours supporting further investigation of the combination of pamiparib with tislelizumab.

Attitudes of health professionals to using routinely collected clinical data for performance feedback and personalised professional development.

OBJECTIVES: To learn the attitudes of health professionals, health informaticians and information communication technology professionals to using data in electronic health records (eHRs) for performance feedback and professional development. DESIGN: Qualitative research in a co-design framework. Health professionals' perceptions of the accessibility of data in eHRs, and barriers to and enablers of using these data in performance feedback and professional development were explored in co-design workshops. Audio recordings of the workshops were transcribed, de-identified, and thematically analysed. SETTING, PARTICIPANTS: A total of nine co-design workshops were held in two major public hospitals in Sydney: three for nursing staff (ten participants), three for doctors (15 participants), and one each for information communication technology professionals (six participants), health informaticians (four participants), and allied health professionals (13 participants). MAIN OUTCOME MEASURES: Key themes related to attitudes of participants to the secondary use of eHR data for improving health care practice. RESULTS: Six themes emerged from the discussions in the workshops: enthusiasm for feeding back clinical data; formative rather than punitive use; peer comparison, benchmarking, and collaborative learning; data access and use; capturing complex clinical narratives; and system design challenges. Barriers to secondary use of eHR data included access to information, measuring performance on the basis of eHR data, and technical questions. CONCLUSIONS: Our findings will inform the development of programs designed to utilise routinely collected eHR data for performance feedback and professional development.

An Investigation of the Impact of Childhood Trauma on Quality of Caregiving in High Risk Mothers: Does Maternal Substance Misuse Confer Additional Risk?

The quality of caregiving is often compromised when mothers have co-occurring difficulties such as substance misuse and problems associated with extreme emotional dysregulation. These, in turn, are associated with poor child outcomes. The aim of the current study was twofold. First, to investigate the potential differences in risk factors associated with poor child outcome by comparing three groups: substance misusing mothers (Substance Misusing Mothers; SMM); mothers matched on demographic characteristics (Matched Comparison Mothers; MCM) and mothers recruited from the community (Matched Control Comparison; MCC). Second, to investigate the underlying mechanisms which are associated with poor child outcome by testing a mediated moderation model to ascertain (i) whether environmental risk and borderline psychopathology was a mediator between maternal childhood trauma and quality of caregiving and (ii) maternal substance misuse status moderated outcome. There were no significant differences found between the SMM and MCM groups on the key variables, but significant differences on all variables for both SMM and MCM compared to CCM. The moderated mediation analysis found that while there was significant mediation of environmental risk and borderline pathology between maternal childhood trauma and child outcome, this was not moderated by maternal substance abuse status. The importance of environmental-risk as a mechanism leading to reduced caregiving quality suggest treatment programs need to consider targeting these factors in high risk families.

Response rates to second-line platinum-based therapy in ovarian cancer patients challenge the clinical definition of platinum resistance.

OBJECTIVE: The aim of this study was to compare response rates and survival in women with "platinum resistant" epithelial ovarian cancer (EOC) who received further platinum-based or non­platinum chemotherapy for treatment at first relapse. METHODS: Patients with high-grade EOC (including fallopian tube and peritoneal cancer) of all histologies recruited to the Australian Ovarian Cancer Study (AOCS) and treated with platinum-based primary chemotherapy were included. Response to second-line chemotherapy, overall survival (OS) and survival after treatment for first progression (OS2) were determined in all histologies and separately in women with high-grade serous tumors. RESULTS: Of the 341 patients classified as platinum-resistant by the 6-month threshold, 243 (71%) were treated with chemotherapy at relapse. CA-125 response rates to platinum-based chemotherapy were significantly higher compared to non­platinum chemotherapy (51% vs 21%, P < 0.001). Among patients with a platinum-free interval (PFI) of 3-6 months, OS2 in patients treated with platinum was significantly longer compared to individuals receiving non­platinum-based treatment (median 17.67 months, 95% CI: 14.79-20.75 vs. 10.62 months, 95% CI: 8.02-12.72, P = 0.022). The patterns were similar when restricted to patients with high-grade serous histology. In patients with PFI <3 months, there was no significant difference in response or survival according to type of second-line treatment. CONCLUSIONS: Our findings further question the use of a 6-month PFI as an arbitrary threshold for subsequent treatment decision-making. Some patients considered "platinum resistant" still derive clinical benefit from platinum-based chemotherapy. Biomarkers of platinum sensitivity are needed in clinical practice to identify potential responders who should be offered re-treatment with platinum.

Multidisciplinary teams and ICT: a qualitative study exploring the use of technology and its impact on multidisciplinary team meetings.

BACKGROUND: Multidisciplinary teams (MDTs) are an integral component in the delivery of health care. This is particularly evident in the delivery of cancer care, where multidisciplinary teams are internationally recognized as the preferred method for service delivery. The use of health information systems and technology are key enabling factors for building the capacity of MDTs to engage in improvement and implementation projects but there is scant research on how MDTs make use of technology and information systems or the kinds of systems needed for them to undertake improvement and implementation research. This paper reports findings on how seven MDTs in cancer care utilized technological and information systems and the barriers and enabling factors that impacted on their uptake. METHODS: Seven multidisciplinary teams from two large metropolitan hospitals participated in the study. Qualitative methods including structured observations and semi structured interviews that explored how teams engaged in research and improvement activities were utilized. Participants were also observed and interviewed in relation to their use of data and health information systems. Findings were subject to content analysis and key themes were identified. Interviews were transcribed and de-identified and key themes were subsequently discussed with participants to allow for member checking and further clarification of findings. RESULTS: A total of 43 MDT meetings across seven tumor streams were observed. Of these, observation notes from 13 meetings contained direct references to emerging technologies and health information systems. Findings from 15 semi-structured interviews were also analyzed in relation to how MDTs used technology in weekly meetings, and the perceived impact of technology. Three broad themes emerged: (1) methods for data collection and use by MDTs, (2) the impact of technology on the MDT meeting environment, and (3) the impact of technology and information systems on clinical decision making. CONCLUSION: The study demonstrates that real time data collection and imaging may improve patient centered care coordination. However, ICTs can be used sub-optimally by teams. We therefore urge additional research to identify the enabling factors that support better collection and use of outcome data from ICT.

A randomized phase III study evaluating pegylated liposomal doxorubicin versus capecitabine as first-line therapy for metastatic breast cancer: results of the PELICAN study.

PURPOSE: The PELICAN trial evaluates for the first time efficacy and safety of pegylated liposomal doxorubicin (PLD) versus capecitabine as first-line treatment of metastatic breast cancer (MBC). METHODS: This randomized, phase III, open-label, multicenter trial enrolled first-line MBC patients who were ineligible for endocrine or trastuzumab therapy. Cumulative adjuvant anthracyclines of 360 mg/m2 doxorubicin or equivalent were allowed. Left ventricular ejection fraction of >50 % was required. Patients received PLD 50 mg/m2 every 28 days or capecitabine 1250 mg/m2 twice daily for 14 days every 21 days. The primary endpoint was time-to-disease progression (TTP). RESULTS: 210 patients were randomized (n = 105, PLD and n = 105, capecitabine). Adjuvant anthracyclines were given to 37 % (PLD) and 36 % (capecitabine) of patients. No significant difference was observed in TTP [HR = 1.21 (95 % confidence interval, 0.838-1.750)]. Median TTP was 6.0 months for both PLD and capecitabine. Comparing patients with or without prior anthracyclines, no significant difference in TTP was observed in the PLD arm (log-rank P = 0.64). For PLD versus capecitabine, respectively, overall survival (median, 23.3 months vs. 26.8 months) and time-to-treatment failure (median, 4.6 months vs. 3.7 months) were not statistically significantly different. Compared to PLD, patients on capecitabine experienced more serious adverse events (P = 0.015) and more cardiac events among patients who had prior anthracycline exposure (18 vs. 8 %; P = 0.31). CONCLUSION: Both PLD and capecitabine are effective first-line agents for MBC.

Embedding continuous quality improvement processes in multidisciplinary teams in cancer care: exploring the boundaries between quality and implementation science.

Objective The aim of the present study was to identify key enabling factors for engaging multidisciplinary teams (MDTs) in cancer care across the spectrum of translational research and quality improvement (QI) projects. Methods The study was conducted in two large Sydney metropolitan hospitals. Qualitative methods, including structured observations of MDT meetings and semi-structured interviews with MDT leaders and champions, were used to identify how teams interact with and generate research and implementation initiatives. Enabling factors for and barriers to the engagement of MDTs in translational research and QI were identified. Results Four key enabling factors emerged from the analysis of data generated from observing 43 MDT meetings and 18 semi-structured interviews: (1) access to high-quality data around individual and team performance; (2) research-active team leaders; (3) having experts, such as implementation scientists, embedded into teams; and (4) having dedicated research or QI-focused meetings. Barriers included a lack of time, administrative support, research expertise and access to real-time data. Conclusions The identification of enabling factors for and barriers to translational research and QI provides evidence for how multidisciplinary cancer care teams may best be engaged in research and QI that aims to improve service and care outcomes. What is known about the topic? MDTs are key to the delivery of cancer care in Australia, but there is scant research into how teams can best be engaged in translating research from basic science through to implementation science and QI. What does this paper add? This paper provides new evidence from an immersive study of cancer care MDTs in two large metropolitan hospitals in Sydney (NSW, Australia), regarding the key enabling factors for and barriers to successful engagement in translational research and QI in cancer care. What are the implications for practitioners? Cancer care professionals in MDTs are presented with an opportunity to embed translational research and QI into cancer care. MDTs can operate as an ideal vehicle to look beyond individual patient outcomes to broader trends and population health outcomes.

Serous ovarian and primary peritoneal cancers: A comparative analysis of clinico-pathological features, molecular subtypes and treatment outcome.

OBJECTIVE: Primary peritoneal cancer is rare and considered equivalent to stage III/IV ovarian cancer, but questions remain concerning its underlying biology, prognosis and optimal management. METHODS: Clinico-pathological and treatment details of primary peritoneal (n=120) and ovarian cancer (n=635) were obtained on women recruited to the Australian Ovarian Cancer Study. Log-rank test was used to compare survival and cox proportional hazards models were fitted to obtain hazard ratios and 95% confidence intervals, both unadjusted and adjusted for age, grade, FIGO stage, residual disease and treatment with neoadjuvant chemotherapy. Molecular subtype was determined by gene expression profiling using published data. RESULTS: Compared with advanced serous ovarian cancer, primary peritoneal cancer patients were older (mean age 65.5 vs. 60.2years, p<0.001), more often treated with neoadjuvant chemotherapy (38.4% vs. 11.4%, p<0.001). Gene expression profiling classified a substantially higher proportion of primary peritoneal carcinomas as C1 (mesenchymal, reactive stromal infiltration) subtype (70.6% vs. 32.1%, p=0.029), which was associated with lower complete surgical resection rate. Women with primary peritoneal cancer had significantly shorter progression-free (11.6 vs. 13.6months, p=0.007) and overall survival (31.7 vs. 39.8months, p=0.012). In multivariate analysis, residual disease and neoadjuvant chemotherapy were both independently associated with increased risk of progression and death. CONCLUSIONS: Primary peritoneal cancer patients were more frequently treated with neoadjuvant chemotherapy and had inferior survival. Different tumor biology characterized by activated stromal fibrosis in primary peritoneal cancer may underlie the differences in treatment and clinical outcome.

A mixed methods approach to developing and evaluating oncology trainee education around minimization of adverse events and improved patient quality and safety.

BACKGROUND: Adverse events are a significant quality and safety issue in the hospital setting due to their direct impact on patients. Additionally, such events are often handled by junior doctors due to their direct involvement with patients. As such, it is important for health care organizations to prioritize education and training for junior doctors on identifying adverse events and handling them when they occur. The Cancer Cup Challenge is an educational program focuses on quality improvement and adverse event awareness targeting for junior oncology doctors across three international sites. METHODS: A mixed methodology was used to develop and evaluate the program. The Qstream spaced learning platform was used to disseminate information to participants, as it has been demonstrated to impact on both knowledge and behavior. Eight short case based scenarios with expert feedback were developed by a multidisciplinary advisory committee containing representatives from the international sites. At the conclusion of the course impact on participant knowledge was evaluated using analysis of the metrics collected by the Qstream platform. Additionally, an online survey and semi-structured interviews were used to evaluate engagement and perceived value by participants. RESULTS: A total of 35 junior doctors registered to undertake the Qstream program, with 31 (88.57 %) successfully completing it. Analysis of the Qstream metrics revealed 76.57 % of cases were answered correctly on first attempt. The post-program survey received 17 responses, with 76.47 % indicating cases for the course were interesting and 82.35 % feeling cases were relevant. Finally, 14 participants consented to participate in semi-structured interviews about the program, with feedback towards the course being generally very positive. CONCLUSIONS: Our study demonstrates that an online game is well accepted by junior doctors as a method to increase their quality improvement awareness. Developing effective and sustainable training for doctors is important to ensure positive patient outcomes are maintained in the hospital setting. This is particularly important for junior doctors as they are working closely with patients and learning skills and behaviors, which will influence their practice throughout their careers.
