The predictive effect of primary tumour location in the treatment of metastatic colorectal cancer: a Canadian consensus statement.

In recently published data, the predictive value of primary tumour location for the treatment of metastatic colorectal cancer with available biologic therapies has been explored. Recognizing the potential effect of those data on clinical practice, we convened a meeting of Canadian experts who treat metastatic colorectal cancer to develop a set of national, evidence-based treatment guidelines based on primary tumour location. This report summarizes the relevant evidence and presents the consensus recommendations of those experts.

An initiative to provide emergency healthcare for older people in the community: the impact on carers.

The increase in the size and age of the UK older population has had a major effect on emergency services. Many older people will visit the emergency department but not necessarily require significant clinical intervention. The Paramedic Practitioner in Older People's Support (PPOPS) scheme was set up to provide community-based clinical assessment of older patients contacting the emergency services with minor acute conditions as an alternative approach to emergency department transfer. Patient carers were followed-up to evaluate the impact of this scheme when compared with standard transfer to the emergency department. Postal questionnaires, including items on the level of care provided, satisfaction with care received and carer impact, were administered to 561 carers. The overall response rate was 71.5% (401/561). The carers were predominantly female, approximately 60 years of age and family members, with more than three-quarters providing some form of physical care before the patient episode. Overall, carers did report an increase in the level of care provided before episode, significantly more so in the emergency department group (p=0.003). These increases related to more input needed in supporting physical activities. The carers in the PPOPS group were more likely to report greater satisfaction with their impression of care and staff attitude and would prefer treatment at home for the patient than those in the emergency department group (p<0.001). A minor health event does impact on the life of a carer. However, community-based schemes, such as PPOPS, do not increase the burden on carers and have high levels of satisfaction among this important group of the community.

Impact of COVID-19 on Canadian medical oncologists and cancer care: Canadian Association of Medical Oncologists survey report.

Background: The covid-19 pandemic has presented unprecedented professional and personal challenges for the oncology community. Under the auspices of the Canadian Association of Medical Oncologists, we conducted an online national survey to better understand the impact of the pandemic on the medical oncology community in Canada. Methods: An English-language multiple-choice survey, including questions about demographics, covid-19 risk, use of personal protective equipment (ppe), personal challenges, and chemotherapy management was distributed to Canadian medical oncologists. The survey was open from 30 March to 4 April 2020, and attracted 159 responses. Results: More than 70% of medical oncologists expressed moderate-to-extreme concern about personally contracting covid-19 and about family members or patients (or both) contracting covid-19 from them. Despite that high level of concern, considerable variability in the use of ppe in direct cancer care was reported at the time of this survey, with 33% of respondents indicating no routine ppe use at their institutions and 69% indicating uncertainty about access to adequate ppe. Of the respondents, 54% were experiencing feelings of nervousness or anxiety on most days, and 52% were having feelings of depression or hopelessness on at least some days. Concern about aging parents or family and individual wellness represented the top personal challenges identified. The management of cancer patients has been affected, with adoption of telemedicine reported by 82% of respondents, and cessation of clinical trial accrual reported by 54%. The 3 factors deemed most important for treatment decision-making were■ cancer prognosis and anticipated benefit from treatment,■ risk of treatment toxicity during scarce health care access, and■ patient risk of contracting covid-19. Conclusions: This report describes the results of the first national survey assessing the impact of the covid-19 on Canadian medical oncologists and how they deliver systemic anticancer therapies. We hope that these data will provide a framework to address the challenges identified.

Is it cost effective to introduce paramedic practitioners for older people to the ambulance service? Results of a cluster randomised controlled trial.

BACKGROUND: A scheme to train paramedics to undertake a greater role in the care of older people following a call for an emergency ambulance was developed in a large city in the UK. OBJECTIVES: To assess the cost effectiveness of the paramedic practitioner (PP) scheme compared with usual emergency care. METHODS: A cluster randomised controlled trial was undertaken of PP compared with usual care. Weeks were allocated to the study group at random to the PP scheme either being active (intervention) or inactive (control). Resource use data were collected from routine sources, and from patient-completed questionnaires for events up to 28 days. EQ-5D data were also collected at 28 days. RESULTS: Whereas the intervention group received more PP contact time, it reduced the proportion of emergency department (ED) attendances (53.3% vs 84.0%) and time in the ED (126.6 vs 211.3 minutes). There was also some evidence of increased use of health services in the days following the incident for patients in the intervention group. Overall, total costs in the intervention group were 140 UK pounds lower when routine data were considered (p = 0.63). When the costs and QALY were considered simultaneously, PP had a greater than 95% chance of being cost effective at 20 000 UK pounds per QALY. CONCLUSION: Several changes in resource use are associated with the use of PP. Given these economic results in tandem with the clinical, operational and patient-related benefits, the wider implementation and evaluation of similar schemes should be considered.

Comparison of gemcitabine versus the matrix metalloproteinase inhibitor BAY 12-9566 in patients with advanced or metastatic adenocarcinoma of the pancreas: a phase III trial of the National Cancer Institute of Canada Clinical Trials Group.

PURPOSE: To compare the selective matrix metalloproteinase inhibitor BAY 12-9566 with the nucleoside analog gemcitabine in the treatment of advanced pancreatic cancer. METHODS: Patients with advanced pancreatic adenocarcinoma who had not previously received chemotherapy were randomly assigned to receive BAY 12-9566 800 mg orally bid continuously or gemcitabine 1,000 mg/m2 administered intravenously on days 1, 8, 15, 22, 29, 36, and 43 for the first 8 weeks, and then days 1, 8, and 15 of each subsequent 28-day cycle. The primary end point was overall survival; secondary end points were progression-free survival, tumor response, quality of life, and clinical benefit. The planned sample size of the study was 350 patients. Two formal interim analyses were planned. RESULTS: The study was closed to accrual after the second interim analysis on the basis of the recommendation of the National Cancer Institute of Canada Clinical Trials Group Data Safety Monitoring Committee. There were 277 patients enrolled onto the study, 138 in the BAY 12-9566 arm and 139 in the gemcitabine arm. The rates of serious toxicity were low in both arms. The median survival for the BAY 12-9566 arm and the gemcitabine arm was 3.74 months and 6.59 months, respectively (P <.001; stratified log-rank test). The median progression-free survival for the BAY 12-9566 and gemcitabine arms was 1.68 and 3.5 months, respectively (P <.001). Quality-of-life analysis also favored gemcitabine. CONCLUSION: Gemcitabine is significantly superior to BAY 12-9566 in advanced pancreatic cancer.

Inflammatory breast carcinoma: comparison of survival of those diagnosed clinically, pathologically, or with both features.

There still remains some controversy as to whether or not there is a survival difference in patients with inflammatory breast carcinoma (IBC) with regard to whether they were diagnosed clinically, pathologically, or with both features. We conducted a retrospective chart review of all the patients diagnosed with IBC who were treated at the Nova Scotia Cancer Treatment and Research foundation between the years of 1990 and 1994, inclusive. Fifty-seven patients' charts were reviewed for recurrence or death up until Feb. 16, 1996. The overall survival of the 57 patients was 32 per cent (confidence interval, 16-48%) and 12 per cent (confidence interval, 0-26%) at 3 and 5 years, respectively. The survival times according to presentation (clinical, pathological, or both) at 3 and 5 years were 31 and 10 per cent for the clinically diagnosed group, 56 per cent at 3 years for the pathologically diagnosed group (5-year survival times could not be calculated), and 34 and 20 per cent for the group diagnosed both clinically and pathologically, respectively. Analysis by the log-rank test revealed that there was no significant difference in survival between these three groups. We conclude that there was no statistically significant difference in survival between those patients who presented clinically, pathologically, or with both features.

Pro-innovation bias: the case of the Giant Texas SmokeScream.

A common approach to promoting improvements in school health instruction involves development and dissemination of new curricula and teaching materials. Ironically, potential effects of innovative materials on student outcomes and actual teacher instructional practices rarely are considered important in decisions concerning use of new material. This study examined the impact of a new curricular innovation, the Giant Texas SmokeScream (GTSS), on 512 middle grade students' knowledge, perceptions, and behavioral intent about smoking. The data provided a basis for discussion of what Rogers labeled "pro-innovation bias." Data indicated the program had no effect on students. The GTSS program itself, although popular with schools, was questioned as being atheoretical in its approach to health education and ineffective in its outcomes. These data illustrate the need for programs to be based on sound theory and evaluated rigorously prior to general adoption. Additionally, program evaluations focused solely on student effects are insufficient in their assessment of adoption and implementation practices.

A meta-analysis examining effects of school sexuality education programs on adolescents' sexual knowledge, 1960-1997.

This study analyzed and synthesized findings from selected studies conducted from 1960 through 1997 regarding effects of school sexuality education on adolescents' sexual knowledge. This purpose was achieved using meta-analysis. Sixty-seven studies that met the selection criteria were included in the meta-analysis. The 67 studies reported 72 outcomes regarding sexual knowledge, which were grouped into six independent variables related to knowledge about sexuality. A weighted effect size method developed by Hedges and Olkin was calculated using all studies. For all studies, 97% of weighted effect sizes were positive. The weighted average effect size on sexual knowledge across all studies of 0.41 was statistically significant, indicating a significant difference occurred between control and experimental groups' mastery of objectives related to sexual knowledge. It was concluded that sexuality education programs positively affect overall sexual knowledge.

Opinions of rural Texas parents concerning elementary school health education.

Parents of elementary school children in rural east-central Texas were surveyed about their attitudes toward and knowledge of Comprehensive School Health Education. Data indicated widespread support for health education compared to other subject areas. Parents felt alcohol and other drugs, nutrition, and first aid were the most important topics to be covered in elementary school, while sexuality, cancer, and stress were the least important. Parents were most comfortable discussing alcohol and other drugs, family life, and growth and development with their children and least comfortable discussing exercise, cancer, and sexuality. Implications for school health programs are discussed.

School violence: prevalence and intervention strategies for at-risk adolescents.

This study investigated the effects of social-cognitive group intervention on violence avoidance beliefs among at-risk adolescents. Fifty high school students were randomly assigned to an experimental or a control group. The experimental group participated in ten, 2-hour weekly sessions of a social-cognitive intervention. Both groups were administered a questionnaire before, immediately following, and 3 months after the intervention. Findings showed that the social-cognitive intervention did not result in significant differences between the groups on violence avoidance beliefs at posttest or follow-up. In addition, drug/alcohol users and nonusers, fighters and nonfighters, and students threatened at school and those not threatened were compared. Students who used drugs/alcohol and fought in school had significantly lower scores (i.e., a greater belief in using violence as a coping technique) than did students who did not engage in those behaviors.

Eastern Canadian colorectal cancer consensus conference: application of new modalities of staging and treatment of gastrointestinal cancers.

The annual Eastern Canadian Colorectal Cancer Consensus Conference was held in Ottawa, Ontario, October 22-23, 2010. Health care professionals involved in the care of patients with colorectal cancer participated in presentation and discussion sessions for the purpose of developing the recommendations presented here. This consensus statement addresses current issues in the management of colorectal cancer, such as the use of epidermal growth factor inhibitors in metastatic colon cancer, the benefit of calcium and magnesium with oxaliplatin chemotherapy, the role of microsatellites in treatment decisions for stage II colon cancer, the staging and treatment of rectal cancer, and the management of colorectal and metastatic pancreatic cancers.

Canadian Expert Group consensus recommendations: KRAS testing in colorectal cancer.

Monoclonal antibodies against the epidermal growth factor receptor (anti-egfr) when used in the treatment of metastatic colorectal cancer are associated with improved survival. Patients whose tumours harbor a KRAS mutation in codon 12 or 13 have been shown not to benefit from anti-egfr antibodies. The importance of KRAS mutation status in the management of patients with metastatic colorectal cancer has led to the elaboration of Canadian consensus recommendations on KRAS testing, with the aim of standardizing practice across Canada and reconciling testing access with the clinical demand for testing. The present guidelines were developed at a Canadian consensus meeting held in Montreal in April 2010. The best available evidence and expertise were used to develop recommendations for various aspects of KRAS testing, including indications and timing for testing, sample requirements, recommendations for reporting requirements, and acceptable turnaround times.
