RESUMO

OBJECTIVE: To describe the clinical, pathological and genomic characteristics of pancreatic cancer with DNA mismatch repair deficiency (MMRD) and proficiency (MMRP). DESIGN: We identified patients with MMRD and MMRP pancreatic cancer in a clinical cohort (N=1213, 519 with genetic testing, 53 with immunohistochemistry (IHC)) and a genomic cohort (N=288 with whole-genome sequencing (WGS)). RESULTS: 12 out of 1213 (1.0%) in the clinical cohort were MMRD by IHC or WGS. Of the 14 patients with Lynch syndrome, 3 (21.4%) had an MMRP pancreatic cancer by IHC, and 4 (28.6%) were excluded because tissue was unavailable for testing. MMRD cancers had longer overall survival after surgery (weighted HR after coarsened exact matching 0.11, 95% CI 0.02 to 0.78, p=0.001). One patient with an unresectable MMRD cancer has an ongoing partial response 3 years after starting treatment with PD-L1/CTLA-4 inhibition. This tumour showed none of the classical histopathological features of MMRD. 9 out of 288 (3.1%) tumours with WGS were MMRD. Despite markedly higher tumour mutational burden and neoantigen loads, MMRD cancers were significantly less likely to have mutations in usual pancreatic cancer driver genes like KRAS and SMAD4, but more likely to have mutations in genes that drive cancers with microsatellite instability like ACV2RA and JAK1. MMRD tumours were significantly more likely to have a basal-like transcriptional programme and elevated transcriptional markers of immunogenicity. CONCLUSIONS: MMRD pancreatic cancers have distinct clinical, pathological and genomic profiles. Patients with MMRD pancreatic cancer should be considered for basket trials targeting enhanced immunogenicity or the unique genomic drivers in these malignancies.

RESUMO

Safety of regorafenib in hepatocellular carcinoma (HCC) recurrence after liver transplantation (LT) has been recently demonstrated. We aimed to assess the survival benefit of regorafenib compared with best supportive care (BSC) in LT patients after sorafenib discontinuation. This observational multicenter retrospective study included LT patients with HCC recurrence who discontinued first-line sorafenib. Group 1 comprised regorafenib-treated patients, whereas the control group was selected among patients treated with BSC due to unavailability of second-line options at the time of sorafenib discontinuation and who were sorafenib-tolerant progressors (group 2). Primary endpoint was overall survival (OS) of group 1 compared with group 2. Secondary endpoints were safety and OS of sequential treatment with sorafenib + regorafenib/BSC. Among 132 LT patients who discontinued sorafenib included in the study, 81 were sorafenib tolerant: 36 received regorafenib (group 1) and 45 (group 2) received BSC. Overall, 24 (67%) patients died in group 1 and 40 (89%) in group 2: the median OS was significantly longer in group 1 than in group 2 (13.1 versus 5.5 months; P < 0.01). Regorafenib treatment was an independent predictor of reduced mortality (hazard ratio, 0.37; 95% confidence interval [CI], 0.16-0.89; P = 0.02). Median treatment duration with regorafenib was 7.0 (95% CI, 5.5-8.5) months; regorafenib dose was reduced in 22 (61%) patients for adverse events and discontinued for tumor progression in 93% (n = 28). The median OS calculated from sorafenib start was 28.8 months (95% CI, 17.6-40.1) in group 1 versus 15.3 months (95% CI, 8.8-21.7) in group 2 (P < 0.01). Regorafenib is an effective second-line treatment after sorafenib in patients with HCC recurrence after LT.

RESUMO

BACKGROUND: Routine early palliative care (EPC) improves quality of life (QoL) for patients with advanced cancer, but it may not be necessary for all patients. We assessed the feasibility of Symptom screening with Targeted Early Palliative care (STEP) in a phase II trial. METHODS: Patients with advanced cancer were recruited from medical oncology clinics. Symptoms were screened at each visit using the Edmonton Symptom Assessment System-revised (ESAS-r); moderate to severe scores (screen-positive) triggered an email to a palliative care nurse, who called the patient and offered EPC. Patient-reported outcomes of QoL, depression, symptom control, and satisfaction with care were measured at baseline and at 2, 4, and 6 months. The primary aim was to determine feasibility, according to predefined criteria. Secondary aims were to assess whether STEP identified patients with worse patient-reported outcomes and whether screen-positive patients who accepted and received EPC had better outcomes over time than those who did not receive EPC. RESULTS: In total, 116 patients were enrolled, of which 89 (77%) completed screening for ≥70% of visits. Of the 70 screen-positive patients, 39 (56%) received EPC during the 6-month study and 4 (6%) received EPC after the study end. Measure completion was 76% at 2 months, 68% at 4 months, and 63% at 6 months. Among screen-negative patients, QoL, depression, and symptom control were substantially better than for screen-positive patients at baseline (all P<.0001) and remained stable over time. Among screen-positive patients, mood and symptom control improved over time for those who accepted and received EPC and worsened for those who did not receive EPC (P<.01 for trend over time), with no difference in QoL or satisfaction with care. CONCLUSIONS: STEP is feasible in ambulatory patients with advanced cancer and distinguishes between patients who remain stable without EPC and those who benefit from targeted EPC. Acceptance of the triggered EPC visit should be encouraged. CLINICALTRIALS: gov identifier: NCT04044040.

RESUMO

Emergency department visits and hospitalisations (ED+H) during systemic therapy are undesirable for both patients and the health system. We undertook a systematic literature review and meta-analysis to evaluate the frequency of unplanned all-cause and treatment-related ED+H among adults receiving adjuvant or palliative-intent systemic therapy for all cancers. Randomised controlled trials (RCT) and observational studies (OS) reporting ED+H were identified from Medline and EMBASE from inception to June 2016. Quality was assessed using modified STROBE, CONSORT or PRISMA guidelines, depending on study type. A total of 112 OS (308,662 patients) and 26 RCTs (16,081 patients) met inclusion criteria. Most articles focused on palliative treatment (59%) delivered as first-line, in breast, lung and colorectal cancers. Only 20 articles reported ED frequency. Treatment-related and all-cause hospitalisations were more common in routine practice than in RCTs (29% vs. 16% and 42% vs. 28% respectively); frequency varied by treatment intent and tumour site. Methodological issues were common, particularly poor definition of the at-risk period. Hospitalisations are common, especially in unselected populations, but few articles report this and do so poorly. Routine, standardised reporting of ED+H during chemotherapy should be included in RCT reports and evaluated in routine care following adoption of new treatments.

RESUMO

BACKGROUND: Cancer patients receiving chemotherapy have high symptom needs that can negatively impact quality of life and result in high rates of unplanned acute care visits. Remote monitoring tools may improve symptom management in this patient population. OBJECTIVE: This study aimed to design a prototype tool to facilitate remote management of chemotherapy-related toxicities. METHODS: User needs were assessed using a participatory, user-centered design methodology that included field observation, interviews, and focus groups, and then analyzed using affinity diagramming. Participants included oncology patients, caregivers, and health care providers (HCPs) including medical oncologists, oncology nurses, primary care physicians, and pharmacists in Ontario, Canada. Overarching themes informed development of a Web-based prototype, which was further refined over 2 rounds of usability testing with end users. RESULTS: Overarching themes were derived from needs assessments, which included 14 patients, 1 caregiver, and 12 HCPs. Themes common to both patients and HCPs included gaps and barriers in current systems, need for decision aids, improved communication and options in care delivery, secure access to credible and timely information, and integration into existing systems. In addition, patients identified missed opportunities, care not meeting their needs, feeling overwhelmed and anxious, and wanting to be more empowered. HCPs identified accountability for patient management as an issue. These themes informed development of a Web-based prototype (bridges), which included toxicity tracking, self-management advice, and HCP communication functionalities. Usability testing with 11 patients and 11 HCPs was generally positive; however, identified challenges included tool integration into existing workflows, need for standardized toxicity self-management advice, issues of privacy and consent, and patient-tailored information. CONCLUSIONS: Web-based tools integrating just-in-time self-management advice and HCP support into routine care may address gaps in systems for managing chemotherapy-related toxicities. Attention to the integration of new electronic tools into self-care by patients and practice was a strong theme for both patients and HCP participants and is a key issue that needs to be addressed for wide-scale adoption.

RESUMO

PURPOSE OF REVIEW: Many studies have examined the effects of adjuvant bisphosphonates on long-term breast cancer outcomes. However, results have been inconsistent. Here, we review the evidence for their role in early breast cancer. RECENT FINDINGS: In a recent meta-analysis, no significant decreases in recurrence or breast cancer mortality were observed in the overall population. In postmenopausal women, statistically significant, but modest, reductions in distant recurrence were observed, driven by decreased bone recurrence. This translated to decreased breast cancer mortality. While most individual studies were not performed exclusively in postmenopausal patients and were not adequately powered to detect subgroup effects based on menopausal status, observed effects were highly consistent. Adjuvant bisphosphonates in postmenopausal women should be considered in individual cases of high-risk patients, where the absolute benefit justifies associated risks. There is no evidence supporting their routine use in premenopausal women except in selected patients receiving ovarian function suppression.

RESUMO

Background: Pancreatic ductal adenocarcinoma (PDAC) presents significant challenges in diagnosis, staging, and appropriate treatment. Furthermore, patients with PDAC often experience complex symptomatology and psychosocial implications that require multi-disciplinary and inter-professional supportive care management from health professionals. Despite these hurdles, the implementation of inter-professional clinic approaches showed promise in enhancing clinical outcomes. To assess the effectiveness of such an approach, we examined the impact of the Wallace McCain Centre for Pancreatic Cancer (WMCPC), an inter-professional clinic for patients with PDAC at the Princess Margaret Cancer Centre (PM). Methods: This retrospective cohort study included all patients diagnosed with PDAC who were seen at the PM before (July 2012-June 2014) and after (July 2014-June 2016) the establishment of the WMCPC. Standard therapies such as surgery, chemotherapy, and radiation therapy remained consistent across both time periods. The cohorts were compared in terms of survival rates, disease stage, referral patterns, time to treatment, symptoms, and the proportion of patients assessed and supported by nursing and allied health professionals. Results: A total of 993 patients were included in the review, comprising 482 patients pre-WMCPC and 511 patients post-WMCPC. In the multivariate analysis, adjusting for ECOG (Eastern Cooperative Oncology Group) and stage, it was found that post-WMCPC patients experienced longer median overall survival (mOS, HR 0.84, 95% CI 0.72-0.98, p = 0.023). Furthermore, the time from referral to initial consultation date decreased significantly from 13.4 to 8.8 days in the post-WMCPC cohort (p < 0.001), along with a reduction in the time from the first clinic appointment to biopsy (14 vs. 8 days, p = 0.022). Additionally, patient-reported well-being scores showed improvement in the post-WMCPC cohort (p = 0.02), and these patients were more frequently attended to by nursing and allied health professionals (p < 0.001). Conclusions: The implementation of an inter-professional clinic for patients diagnosed with PDAC led to improvements in overall survival, patient-reported well-being, time to initial assessment visit and pathological diagnosis, and symptom management. These findings advocate for the adoption of an inter-professional clinic model in the treatment of patients with PDAC.

RESUMO

BACKGROUND: An especially significant event in the patient-oncologist relationship is the initial consultation, where many complex topics-diagnosis, treatment intent, and often, prognosis-are discussed in a relatively short period of time. This study aimed to measure patients' understanding of the information discussed during their first medical oncology visit and their satisfaction with the communication from medical oncologists. METHODS: Between January and August 2021, patients without prior systemic treatment of their gastrointestinal malignancy (GI) attending the Princess Margaret Cancer Centre (PMCC) were approached within 24 h of their initial consultation to complete a paper-based questionnaire assessing understanding of their disease (diagnosis, treatment plan/intent, and prognosis) and satisfaction with the consultation. Medical oncology physicians simultaneously completed a similar questionnaire about the information discussed at the initial visit. Matched patient-physician responses were compared to assess the degree of concordance. RESULTS: A total of 184 matched patient-physician surveys were completed. The concordance rates for understanding of diagnosis, treatment plan, treatment intent, and prognosis were 92.9%, 59.2%, 66.8%, and 59.8%, respectively. After adjusting for patient and physician variables, patients who reported treatment intent to be unclear at the time of the consultation were independently associated with lower satisfaction scores (global p = 0.014). There was no statistically significant association between patient satisfaction and whether prognosis was disclosed (p = 0.08). CONCLUSION: An in-depth conversation as to what treatment intent and prognosis means is reasonable during the initial medical oncology consultation to ensure patients and caregivers have a better understanding about their cancer.

RESUMO

Background: With the emergence of mutation-based systemic therapies for patients with advanced thyroid cancer, molecular profiling has become an important component of care. Although next-generation sequencing (NGS) gene panels are accessible to clinicians, there is no consensus on the optimal approach to testing. This study investigates the clinical application of NGS results in the management of advanced thyroid cancer. Methods: Patients with advanced thyroid cancer with NGS completed as part of the Integrated Molecular Profiling in Advanced Cancers Trial (IMPACT; NCT01505400) or Ontario-wide Cancer TArgeted Nucleic Acid Evaluation (OCTANE; NCT02906943) clinical trials at the Princess Margaret Cancer Centre were included. Electronic medical records were reviewed to collect clinicopathologic and treatment data. The OncoKB framework was used to categorize molecular alterations based on levels of actionability. Patients with an actionable alteration by OncoKB framework who had treatment with a drug targeting the alteration were categorized as receiving "matched" therapy. Time-to-event data were analyzed using the Kaplan-Meier method. This study was approved by the University Health Network Research Ethics Board (ID# 19-5888). Results: NGS was performed on 118 patients with advanced thyroid cancer between 2013 and 2020. The most common molecular alterations included BRAF V600E (62%) and NRAS (15%) mutations in papillary thyroid cancer, RET alterations (78%) in medullary thyroid cancer, and BRAF V600E (38%) and TP53 (62%) mutations in anaplastic thyroid cancer. Actionable alterations were found in 87% of patients, and 57% of patients had at least one Level 1 or 2 alteration for which Food and Drug Administration (FDA)-approved drug is available. BRAF and RET alterations made up 86% of Level 1 and 2 alterations. A matched therapeutic approach was undertaken in 13% of patients. Conclusion: This study uses a structured framework to analyze the actionability and clinical use of NGS results in advanced thyroid cancer. Most patients had at least one potentially actionable mutation and 57% of patients had at least one Level 1 or 2 alteration, predominantly driven by BRAF V600E and RET alterations. This study rationalizes the need for routine multigene NGS testing or reflex BRAF and RET testing in the management of patients with advanced thyroid cancer.

RESUMO

BACKGROUND: People with cancer are at risk for initial, late, and long-term effects of cancer and its treatments. Cancer rehabilitation (CR) focuses on prevention/treatment of these sequelae and optimization of physical, social, and vocational functioning. Our center has a multidisciplinary impairment-driven outpatient CR program, but referrals of patients with GI cancer were low. AIMS: We aimed (for 2019, relative to 2018) (1) to increase CR referrals of patients with GI cancer by 50% and (2) to increase the proportion of referrals coming from oncologists. Balancing measures included inappropriate referrals and cancellations. METHODS: A rapid cycle improvement approach was used to optimize GI referrals to the CR program. Barriers to CR referral were identified through a literature review and informal interviews of GI clinicians. Barriers included (a) knowledge of CR program existence, (b) awareness of the referral process, (c) time, and (d) lack of CR program exposure. The team used Plan-Do-Study-Act (PDSA) cycles every 2 months from January to December 2019 to address barriers. A p-chart was used to analyze the results. RESULTS: PDSA cycles included CR program advertisement, a presentation to GI staff, nurse-led patient identification, patient-facing posters, and clinician thank-you emails. The p-chart showed a 100% relative increase in referral numbers and an improvement in the percentage of patients referred by oncologists from 51% to 75%. There was no significant change in inappropriate referrals or cancellations. CONCLUSION: Through PDSA cycles, we improved the total number of patients with GI cancer and percentage referred by an oncologist to a CR program. Future work will assess sustainability.

RESUMO

OBJECTIVES: Radiotherapy is a key cancer treatment modality but is poorly understood by doctors. We sought to evaluate radiation oncology (RO) teaching in medical schools within the United Kingdom (UK) and Republic of Ireland (RoI), as well as any impacts on RO teaching delivery from the coronavirus disease 2019 (COVID-19) pandemic. METHODS: A bespoke online survey instrument was developed, piloted and distributed to oncology teaching leads at all UK and RoI medical schools. Questions were designed to capture information on the structure, format, content and faculty for RO teaching, as well as both the actual and the predicted short- and long-term impacts of COVID-19. RESULTS: Responses were received from 29/41 (71%) UK and 5/6 (83%) RoI medical schools. Pre-clinical and clinical oncology teaching was delivered over a median of 2 weeks (IQR 1-6), although only 9 (27%) of 34 responding medical schools had a standalone RO module. RO teaching was most commonly delivered in clinics or wards (n = 26 and 25 respectively). Few medical schools provided teaching on the biological basis for radiotherapy (n = 11) or the RO career pathway (n = 8), and few provide teaching delivered by non-medical RO multidisciplinary team members. There was evidence of short- and long-term disruption to RO teaching from COVID-19. CONCLUSIONS: RO teaching in the UK and RoI is limited with minimal coverage of relevant theoretical principles and little exposure to radiotherapy departments and their non-medical team members. The COVID-19 pandemic risks exacerbating trainee doctors' already constrained exposure to radiotherapy. ADVANCES IN KNOWLEDGE: This study provides the first analysis of radiotherapy-related teaching in the UK and RoI, and the first to explore the impact of the COVID-19 pandemic on radiationoncology teaching.

RESUMO

BACKGROUND: We assessed long-term patient-reported dysphagia and xerostomia outcomes following definitive surgical management with transoral robotic surgery (TORS) in patients with oropharyngeal cancer (OPC) via a cross-sectional survey study. METHODS: Patients with OPC managed with primary oropharyngeal surgery as definitive treatment at least 1 year ago between 2015 and 2019 were identified. The M. D. Anderson Dysphagia Inventory (MDADI) and Xerostomia Inventory (XI) scores were compared across treatment types (i.e., no adjuvant therapy [TORS-A] vs. adjuvant radiotherapy [TORS+RT] vs. adjuvant chemoradiotherapy [TORS+CT/RT]). RESULTS: The sample had 62 patients (10 TORS-A, 30 TORS+RT, 22 TORS+CT/RT). TORS-A had clinically and statistically significantly better MDADI scores than TORS+RT (p = 0.03) and TORS+CT/RT (p = 0.02), but TORS+RT and TORS+CT/RT were not significantly different. TORS-A had clinically and statistically significantly less XI than TORS+RT (p < 0.01) and TORS+CT/RT (p < 0.01). CONCLUSIONS: Patients with OPC who have undergone TORS+RT or TORS+CT/RT following surgery face clinically worse dysphagia and xerostomia outcomes relative to patients who undergo TORS-A.

RESUMO

In a retrospective review, we identified 332 patients with 338 pathologically diagnosed primary oropharyngeal carcinomas (OPC) between January 2013 and March 2020 with known p16/HPV status from a tumor registry at Northwestern Memorial Hospital. The tumors predominantly involved the palatine tonsil (51 %) and the base of the tongue/lingual tonsil (38 %). The most common type of cancer was non-keratinizing squamous cell carcinoma (60 %), and the majority of primaries were p16 positive/HPV-mediated (86 %). A cohort of p16 positive/HPV mediated OPC (27/283, 9.5 %) presented with aggressive clinical behavior, including multiple distant metastases at unusual sites. Tumor size >2 cm and the presence of tumor anaplasia/multinucleation were significantly associated with an increased rate of distant metastases in p16 positive/HPV mediated cases, both in unadjusted and adjusted analyses (all P < 0.05). Of the 332 individuals in the overall cohort, 38 individuals died due to their disease within the observed follow-up time. Among the 283 patients with p16 positive/HPV mediated tumors, survival was estimated at 97 % (95 % CI 95 %, 100 %) at 1 year, 95 % (95 % CI 92 %, 98 %) at 2 years, and 80 % (95 % CI 72 %, 89 %) at 5 years. The presence of tumor anaplasia/multinucleation and distant metastasis were both significantly associated with poorer disease-specific survival in p16 positive/HPV mediated cases (both P < 0.05), with the survival effect of tumor anaplasia/multinucleation likely mediated in part through its association with distant metastasis. For p16 positive/HPV-mediated OPC, age, smoking status, tumor status, and lymph node status were not significantly associated with disease-specific survival in our study.

RESUMO

Background: The COVID-19 pandemic has put enormous pressure on hospital resources, and has affected all aspects of patient care. As operative volumes decrease, cancer surgeries must be triaged and prioritized with careful thought and attention to ensure maximal benefit for the maximum number of patients. Peritoneal malignancies present a unique challenge, as surgical management can be resource intensive, but patients have limited non-surgical treatment options. This review summarizes current data on outcomes and resource utilization to help inform decision-making and case prioritization in times of constrained health care resources. Methods: A rapid literature review was performed, examining surgical and non-surgical outcomes data for peritoneal malignancies. Narrative data synthesis was cross-referenced with relevant societal guidelines. Peritoneal malignancy surgeons and medical oncologists reviewed recommendations to establish a national perspective on case triage and mitigating treatment strategies. Results and Conclusions: Triage of peritoneal malignancies during this time of restricted health care resource is nuanced and requires multidisciplinary discussion with consideration of individual patient factors. Prioritization should be given to patients where delay may compromise resectability of disease, and where alternative treatment options are lacking. Mitigating strategies such as systemic chemotherapy and/or surgical deferral may be utilized with close surveillance for disease stability or progression, which may affect surgical urgency. Unique hospital capacity, and ability to manage the complex post-operative course for these patients must also be considered to ensure patient and system needs are aligned.

RESUMO

BACKGROUND: Despite a lack of improvement in overall survival (OS) with doxorubicin-based combinations over doxorubicin alone in advanced STS, the role of multi-agent chemotherapy remains poorly defined. METHODS: We conducted a systematic review and meta-analysis to evaluate benefits and harms of multi-agent chemotherapy in advanced STS. Eligible studies were randomized trials of chemotherapy in advanced STS comparing single agent to multi-agent therapy. Data from studies reporting a hazard ratio (HR) and 95% confidence intervals (CI) for OS and progression-free survival (PFS) were pooled in a meta-analysis. Meta-regression was utilized to explore the association between efficacy (OS and PFS) and both toxicity and dose intensity. RESULTS: We identified 22 trials published between 1974 and April 2016 and comprising 5044 patients. Overall, multi-agent chemotherapy was associated with improved OS (HR:0.79, p = 0.02), and borderline improvement in PFS (HR:0.86, p = 0.05). While the effect on OS was similar in trials with non-anthracycline controls compared to those with anthracycline controls (HR for OS 0.73 vs. 0.82, p for difference = 0.63) there was a non-significantly greater effect for multi-agent chemotherapy on PFS in non-anthracycline RCT (HR for PFS 0.73 vs. 0.91, p for difference = 0.13). Compared to studies with cytotoxic therapy-based multi-agent therapy, a non-significantly greater magnitude of effect among studies with biological/cytostatic experimental groups was seen (HR for OS 0.64 vs. 0.86, p for difference = 0.37). There was a borderline significant association between dose reductions (which were more common in combination arms) and worse PFS (beta = 0.70, p = 0.053). CONCLUSION: Multi-agent chemotherapy is associated with a modest, but statistically significant improvement in outcomes in STS. Combining chemotherapy with non-cytotoxic agents might represent a promising strategy.

RESUMO

PLAIN ENGLISH SUMMARY: The Experience Based Design (EBD) approach involves patients, staff and members of the public working together to improve a service. This paper evaluates the methods that are used to involve patients and members of the public in a project that aimed to improve the patient experience at Manchester Clinical Research Facility (MCRF). The aim was to explore what helps staff and members of the public to work well together. An evaluation questionnaire was used to get feedback from staff and public contributors. Questions included whether each person felt that they were able to shape the project; if they received enough training; whether they had enough time to complete each task; how well they thought the group worked together; and what could be improved. The findings showed that both staff and public contributors felt valued and that they were able to shape the project from the beginning. Training in EBD and research methodology, and providing enough time to complete each task helped to build relationships and increase confidence when contributing to the project. Personal benefits included a feeling of ownership over a worthwhile and rewarding project, increased awareness of public involvement and gaining new skills. The recommendations for successful involvement of patients and the public in EBD projects will hopefully be helpful for similar projects in the future. ABSTRACT: Background The Experience Based Design (EBD) approach promotes the effective involvement of patients and public contributors by enabling patients, public contributors and staff to co-design projects that aim to improve the patient experience. This approach allows patients and members of the public to have a role in shaping and improving current services. This paper aims to evaluate the EBD process from a public involvement perspective, exploring the barriers and facilitators to building successful working relationships. Methods An open-ended evaluation questionnaire was developed to gain feedback from staff and public contributors who co-produced an EBD project that aimed to improve the patient experience at Manchester CRF. Questions explored what worked well, how the project could be improved, and the benefits of being involved. Results Our findings highlight the importance of providing opportunities for staff, patients and members of the public to build relationships in order to feel confident in voicing their opinions. This can be achieved by training both staff and public contributors in EBD methodology to reduce any power imbalance that may exist. Negotiating adequate time to complete tasks and debate the best way forward also allows everyone to fully contribute to the project. Each individual felt that their contribution was valued and that they shaped the final action plan. Both public contributors and staff listed a number of personal benefits from their involvement in the project. This included a feeling of ownership over a worthwhile and rewarding project, increased awareness of public involvement in EBD projects and gaining new skills. Conclusion This evaluation provides recommendations for best practice for effectively involving public contributors in an EBD methodology. These findings aim to encourage a more consistent approach to EBD across organisations.

RESUMO

In the last few years there have been significant advances in knowledge related to the treatment of post-menopausal women with early stage breast cancer. These include new information about the survival benefits with hormonal therapies and bone targeted treatments as well as identification of patient populations who may be able to avoid toxic treatments. In this paper we discuss these advances and provide suggested management algorithms.

RESUMO

PURPOSE: Randomized controlled trials (RCTs) in soft tissue sarcoma (STS) have used varying end points. The surrogacy of intermediate end points, such as progression-free survival (PFS), response rate (RR), and 3-month and 6-month PFS (3moPFS and 6moPFS) with overall survival (OS), remains unknown. The quality of efficacy and toxicity reporting in these studies is also uncertain. METHODS: A systematic review of systemic therapy RCTs in STS was performed. Surrogacy between intermediate end points and OS was explored using weighted linear regression for the hazard ratio for OS with the hazard ratio for PFS or the odds ratio for RR, 3moPFS, and 6moPFS. The quality of reporting for efficacy and toxicity was also evaluated. RESULTS: Fifty-two RCTs published between 1974 and 2014, comprising 9,762 patients, met the inclusion criteria. There were significant correlations between PFS and OS (R = 0.61) and between RR and OS (R = 0.51). Conversely, there were nonsignificant correlations between 3moPFS and 6moPFS with OS. A reduction in the use of RR as the primary end point was observed over time, favoring time-based events (P for trend = .02). In 14% of RCTs, the primary end point was not met, but the study was reported as being positive. Toxicity was comprehensively reported in 47% of RCTs, whereas 14% inadequately reported toxicity. CONCLUSION: In advanced STS, PFS and RR seem to be appropriate surrogates for OS. There is poor correlation between OS and both 3moPFS and 6moPFS. As such, caution is urged with the use of these as primary end points in randomized STS trials. The quality of toxicity reporting and interpretation of results is suboptimal.

RESUMO

IMPORTANCE: Understanding the risk of hospitalization due to treatment-related toxic effects is essential for patients, their clinicians, and health systems. Unplanned hospitalizations represent potential gaps in patient care; definition of these gaps allows characterization and identification of areas for quality improvement. OBJECTIVE: To compare the rates of hospitalization in patients with metastatic non-small-cell lung cancer (mNSCLC) receiving chemotherapy in the "real world" vs clinical trial settings and to identify factors associated with hospitalization. EVIDENCE REVIEW: A systematic review of Medline and EMBASE was conducted for records dating from database inception (1946 and 1974, respectively) through December 2014 to identify articles reporting rates of hospitalization during chemotherapy in patients with cancer. Both observational studies and clinical trials were eligible. This report focuses on patients with mNSCLC receiving chemotherapy because data were available for this clinical scenario in both the clinical trial and observational setting, allowing comparison. Summary statistics were used to describe results, and the χ2 test was used to compare hospitalization rates. FINDINGS: Of the 74 articles reporting hospitalization rates during chemotherapy, 10 studies, all published after 2004, examined chemotherapy in mNSCLC, 5 randomized clinical trials (3962 patients) and 5 observational studies (8624 patients). Chemotherapy regimens included doublet therapy, single-agent therapy, or chemotherapy type unspecified. The real world cohort was older (71 vs 63 years). All real world studies reported on comorbidities, while clinical trials reported performance status. The aggregate hospitalization rate among real world patients was significantly higher than among trial patients (51% vs 16%) (odds ratio, 7.7; 95% CI, 7.0-8.4; P < .001). Performance status and type of chemotherapy were associated with hospitalization during chemotherapy in clinical trials, while type of chemotherapy was a risk factor in observational studies. CONCLUSIONS AND RELEVANCE: Clinical trials in mNSCLC consistently report significantly lower rates of hospitalization than reports of real world cohorts of patients undergoing similar therapies. However, very few clinical trials report hospitalization information.
