Examining the development of information needs assessment tools for use in the cancer context: A scoping and critical review.

BACKGROUND: Information needs are one of the most common unmet supportive care needs of those living with cancer. Little is known about how existing tools for assessing information needs in the cancer context have been created or the role those with lived cancer experience played in their development. OBJECTIVES: This review aimed to characterize the development and intended use of existing cancer specific information needs assessment tools. METHODS: A systematic scoping review was conducted using a peer-reviewed protocol informed by recommendations from the Joanna Briggs Institute and the Prefered Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) checklist. RESULTS: Twenty-one information needs assessment tools were included. Most tools were either breast cancer (n = 8) or primary tumor nonspecific (n = 8). Patients and informal carers participated in initial identification of questionnaire items in the minority of cases (n = 6) and were more commonly involved in reviewing the final questionnaire before use or formal psychometric testing (n = 9). Most questionnaires were not assessed for validity or reliability using rigorous quantitative psychometric testing. SIGNIFICANCE OF RESULTS: Existing tools are generally not designed to provide a rigorous assessment of informational needs related to a specific cancer challenge and are limited in how they have been informed by those with lived cancer experience. Tools are needed that both rigirously address information needs for specific cancer challenges and that have been developed in partnership with those who have experienced cancer. Future directions should include understanding barriers and facilitators to developing such tools.

No evidence of disease versus residual disease in long-term responders to first-line HER2-targeted therapy for metastatic breast cancer.

BACKGROUND: Long-term response to HER2-targeted therapies is infrequent in metastatic breast cancer (MBC). We evaluated clinical characteristics of HER2-positive MBC patients with no evidence of disease (NED) vs residual disease (RES) experiencing long-term response to first-line HER2-targeted therapy. METHODS: Patients receiving first-line chemotherapy-trastuzumab (CT) or taxane-trastuzumab-pertuzumab (THP) with response duration ≥2-fold higher than in phase II/III trials (CT [18.2 months]; THP [40.4 months]) were included. Clinical characteristics and radiographic review for NED or RES was evaluated by Cox-regression (hazard ratio; HR) or Kaplan-Meier (log-rank). Characteristics associated with NED were evaluated by logistic regression (Odds; OR). RESULTS: From 01/2005-01/2016, N = 103 (4.6%) patients were identified. In multivariate analyses, NED (N = 46) showed improved progression-free (PFS) and overall survival (OS) [p < 0.001] versus RES (N = 57), with high 5-year PFS/OS for NED (93.2%/97.4%) relative to RES (10.6%/61.3%). Premenopausal status (p = 0.006), de-novo metastases (p = 0.002), and no palliative radiotherapy (p = 0.01) were associated with NED. Overall, 6/7 (85.7%) patients with NED were alive and disease-free after discontinuing HER2 treatment (≥1 year) versus 1/17 (5.9%) with RES. CONCLUSIONS: Long-term responders with NED have better survival compared to RES. Premenopausal status and de novo metastatic disease are associated with NED. Prospective studies of HER2 therapy discontinuation with NED in MBC are warranted.

The Impact of Chronic Kidney Disease in Patients With Locally Advanced Rectal Cancer Treated With Neoadjuvant Chemoradiation.

BACKGROUND: Patients with chronic kidney disease are commonly excluded from clinical trials. The impact of chronic kidney disease on outcomes in patients with locally advanced rectal cancer has not been previously studied. OBJECTIVE: This study aimed to investigate the impact of chronic kidney disease on outcomes in patients with locally advanced rectal cancer. DESIGN: This is a multi-institutional, retrospective cohort study. SETTINGS: This study was conducted at academic and community cancer centers participating in the Canadian Health Outcomes Research Database Consortium Rectal Cancer Database. PATIENTS: Consecutive patients with locally advanced rectal cancer undergoing neoadjuvant chemoradiation before curative-intent surgery from 2005 to 2013 were selected. MAIN OUTCOME MEASURES: Disease-free survival, overall survival, pathologic complete response, and neoadjuvant chemotherapy/radiotherapy completion rate were the primary outcomes measured. RESULTS: A total of 1254 patients were included. Median age was 62, and 29%/69% had clinical stage II and III disease. Median estimated creatinine clearance was 93 mL/min, with 11% <60 mL/min (n = 136). There was no significant difference in the completion rate of neoadjuvant chemotherapy (82% vs 85%, p = 0.36) or radiotherapy (93% vs 95%, p = 0.45) between patients with and without chronic kidney disease. Patients with chronic kidney disease were less likely to receive adjuvant chemotherapy (63% vs 77%, p < 0.01). On multivariate analysis, patients with chronic kidney disease had decreased disease-free survival (HR, 1.37; 95% CI, 1.03-1.82; p = 0.03) but not overall survival (HR, 1.23; 95% CI, 0.88-1.75; p = 0.23) or pathologic complete response (OR, 0.83; 95% CI, 0.50-1.39; p = 0.71). LIMITATIONS: This study was limited by its retrospective design and by limited events for overall survival analysis. CONCLUSIONS: In patients with locally advanced rectal cancer undergoing neoadjuvant chemoradiation, baseline chronic kidney disease was associated with less use of adjuvant chemotherapy and decreased disease-free survival. Chronic kidney disease was not independently associated with neoadjuvant chemotherapy/radiotherapy completion rate, pathologic complete response, or overall survival. These data suggest that patients with locally advanced rectal cancer with chronic kidney disease may have distinct outcomes and, accordingly, the results of landmark clinical trials may not be generalizable to this population.

LA REPERCUSIN DE LA ENFERMEDAD RENAL CRNICA EN PACIENTES CON CNCER DE RECTO LOCALMENTE AVANZADO TRATADOS CON QUIMIORRADIOTERAPIA NEOADYUVANTE: ANTECEDENTES:Los pacientes con enfermedad renal crónica generalmente se excluyen de los ensayos clínicos. La repercusión de la enfermedad renal crónica en el desenlace en pacientes con cáncer de recto localmente avanzado no se ha estudiado previamente.OBJETIVO:Investigar la repercusión de la enfermedad renal crónica en los desenlaces en pacientes con cáncer de recto localmente avanzado.DISEÑO:Estudio de cohorte retrospectivo multiinstitucional.ESCENARIO:Centros oncológicos académicos y comunitarios que participan en la base de datos de cáncer rectal del consorcio CHORD.PACIENTES:Pacientes consecutivos con cáncer de recto localmente avanzado, tratados con quimiorradioterapia neoadyuvante, previa a la cirugía con intención curativa del 2005 al 2013.PRINCIPALES VARIABLES EVALUADAS:Sobrevida libre de enfermedad, sobrevida global, respuesta patológica completa, tasa de conclusión de quimioterapia / radioterapia neoadyuvante.RESULTADOS:Se incluyeron 1254 pacientes. El promedio de edad fue de 62, y el 29% / 69% tenían enfermedad en estadio clínico II y III, respectivamente. El promedio de la depuración de creatinina estimada fue de 93 mililitros / minuto, con un 11% <60 mililitros / minuto (n = 136). No hubo diferencias significativas en la tasa de conclusión de la quimioterapia neoadyuvante (82% vs 85%, p = 0,36) o radioterapia (93% vs 95%, p = 0,45) entre pacientes con y sin enfermedad renal crónica. Los pacientes con enfermedad renal crónica tenían menos probabilidades de recibir quimioterapia adyuvante (63% contra el 77%, p <0,01). En el análisis multivariado, los pacientes con enfermedad renal crónica tenían una sobrevida libre de enfermedad menor (HR 1,37, IC 95% 1,03-1,82, p = 0,03) pero no en la sobrevida global (HR 1,23, IC 95% 0,88-1,75, p = 0,23) o respuesta patológica completa (OR 0,83, IC 95% 0,50-1,39, p = 0,71).LIMITACIONES:Diseño retrospectivo y acontecimientos limitados para el análisis de sobrevida global.CONCLUSIONES:En pacientes con cáncer de recto localmente avanzado tratados con quimiorradioterapia neoadyuvante, la enfermedad renal crónica de base se asoció con un menor uso de quimioterapia adyuvante y una menor sobrevida libre de enfermedad. La enfermedad renal crónica no se asoció de forma independiente con la tasa de conclusión de la quimioterapia / radioterapia neoadyuvante, la respuesta patológica completa o la sobrevida global. Estos datos sugieren que los pacientes con cáncer de recto localmente avanzado con enfermedad renal crónica pueden tener resultados distintos y, en consecuencia, los resultados de los ensayos clínicos de referencia pueden no ser generalizables a esta población.

Hospitalizations among early-stage colon cancer patients receiving adjuvant chemotherapy: a real-world study.

OBJECTIVE: To assess the patterns of hospitalizations among early-stage colon cancer patients receiving adjuvant chemotherapy and to identify high-risk groups that may benefit from more careful monitoring in a real-world, population-based context. METHODS: This is a population-based study using linked administrative databases from the province of Alberta, Canada. Any events of hospitalization among patients with non-metastatic colon cancer undergoing upfront surgery followed by adjuvant chemotherapy were reviewed. Multivariable logistic regression analysis was used to examine factors associated with risk of hospitalization, and the impact of hospitalization on overall survival was assessed through Kaplan-Meier estimates and Multivariable Cox regression analysis. RESULTS: A total of 2257 patients were considered eligible and were included in the current analysis, including 483 patients (21.4%) who were hospitalized within 6 months of the start of adjuvant chemotherapy, and 1774 patients (78.6%) who were not. The following factors were associated with a higher hospitalization risk: older age (OR: 1.02; 95% CI 1.01-1.03), higher comorbidity (OR: 1.48; 95% CI 1.31-1.67), women (OR for men versus women: 0.79; 95% CI 0.64-0.98), living in the North zone (OR for Edmonton zone versus North zone: 0.60; 95% CI 0.42-0.87), and CAPOX chemotherapy (OR for CAPOX versus FOLFOX: 1.50; 95% CI 1.12-2.00). Patients with a history of hospitalization during adjuvant chemotherapy had a worse overall survival compared to patients who were not hospitalized (P < 0.001). CONCLUSION: In this study, one out of five colon cancer patients were hospitalized during adjuvant chemotherapy. Older individuals, women, those with higher comorbidity, and those receiving adjuvant CAPOX were more likely to be hospitalized.

Information Access and Use by Patients With Cancer and Their Friends and Family: Development of a Grounded Theory.

BACKGROUND: Information has been identified as a commonly unmet supportive care need for those living with cancer (ie, patients and their friends and family). The information needed to help individuals plan their lives around the consequences of cancer, such as the receipt of health care, is an example of an important informational need. A suitable theory to guide the development of interventions designed to meet this informational need has not been identified by the authors. OBJECTIVE: The aim of this study is to generate a grounded theory capable of guiding the development of interventions designed to assist those living with cancer in meeting their informational needs. METHODS: Classic grounded theory was used to analyze data collected through digitally recorded one-on-one audio interviews with 31 patients with cancer and 29 friends and family members. These interviews focused on how the participants had accessed and used information to plan their lives and what barriers they faced in obtaining and using this information. RESULTS: The theory that emerged consisted of 4 variables: personal projects, cancer as a source of disruption to personal projects, information as the process of accessing and interpreting cancer-related data (CRD) to inform action, and CRD quality as defined by accessibility, credibility, applicability, and framing. CRD quality as a moderator of personal project disruption by cancer is the core concept of this theory. CONCLUSIONS: Informational resources providing accessible, credible, applicable, and positively framed CRD are likely key to meeting the information needs of those affected by cancer. Web-based informational resources delivering high-quality CRD focused on assisting individuals living with cancer in maintaining and planning their personal projects are predicted to improve quality of life. Research is needed to develop and integrate resources informed by this theoretical framework into clinical practice.

Neutrophil-to-lymphocyte and platelet-to-lymphocyte ratios as predictive and prognostic markers in patients with locally advanced rectal cancer treated with neoadjuvant chemoradiation.

BACKGROUND: A standard therapy for locally advanced rectal cancer (LARC) includes fluoropyrimidine (FP)-based neoadjuvant chemoradiation (nCRT). Previous studies have inconsistently demonstrated that baseline neutrophil- and platelet-to-lymphocyte ratios (NLR and PLR) are predictive of response to nCRT or prognostic of outcomes in LARC. METHODS: We reviewed patients with LARC undergoing nCRT followed by surgery from 2005 to 2013 across 8 Canadian cancer centres. Outcome measures of interest were pathological complete response (pCR), disease-free survival (DFS) and overall survival (OS). Logistic regression and Cox proportional hazard models were used to assess for associations between baseline hematologic variables and outcomes. RESULTS: Of 1527 identified patients, 1237 (81%) were included in the DFS/OS analysis. Median age was 62 (range 23-88), 69% were male, and 80% had performance status (PS) 0-1. Twenty-six percent had elevated NLR (≥ 4), and 66% had elevated PLR (≥ 150). Ninety-seven percent of patients received FP-based nCRT, with 96% receiving ≥44 Gy. 81% completed neoadjuvant chemotherapy and 95% completed neoadjuvant radiotherapy, with a pCR rate of 18%. After a median follow-up time of 71 months, 8% developed local recurrence, 22% developed distant recurrence and 24% died. 5-year DFS and OS were 69% (95% CI 66-72%) and 79% (95% CI 77-82%), respectively. In multivariate analyses, elevated baseline NLR and PLR were neither prognostic for DFS and OS nor predictive of pCR. CONCLUSIONS: NLR and PLR were not found to be independently prognostic for DFS or OS and did not predict for pCR in patients with LARC undergoing nCRT followed by surgery.

Immediate-term cognitive impairment following intravenous (IV) chemotherapy: a prospective pre-post design study.

BACKGROUND: Cognitive impairment is commonly reported in patients receiving chemotherapy, but the acuity of onset is not known. This study utilized the psychomotor vigilance test (PVT) and trail-making test B (TMT-B) to assess cognitive impairment immediately post-chemotherapy. METHODS: Patients aged 18-80 years receiving first-line intravenous chemotherapy for any stage of breast or colorectal cancer were eligible. Patient symptoms, peripheral neuropathy and Stanford Sleepiness Scale were assessed. A five-minute PVT and TMT-B were completed on a tablet computer pre-chemotherapy and immediately post-chemotherapy. Using a mixed linear regression model, changes in reciprocal transformed PVT reaction time (mean 1/RT) were assessed. A priori, an increase in median PVT reaction times by > 20 ms (approximating PVT changes with blood alcohol concentrations of 0.04-0.05 g%) was considered clinically relevant. RESULTS: One hundred forty-two cancer patients (73 breast, 69 colorectal, median age 55.5 years) were tested. Post-chemotherapy, mean 1/RT values were significantly slowed compared to pre-chemotherapy baseline (p = 0.01). This corresponded to a median PVT reaction time slowed by an average of 12.4 ms. Changes in PVT reaction times were not correlated with age, sex, cancer type, treatment setting, or use of supportive medications. Median post-chemotherapy PVT reaction time slowed by an average of 22.5 ms in breast cancer patients and by 1.6 ms in colorectal cancer patients. Post-chemotherapy median PVT times slowed by > 20 ms in 57 patients (40.1%). Exploratory analyses found no statistically significant association between the primary outcome and self-reported anxiety, fatigue or depression. TMT-B completion speed improved significantly post-chemotherapy (p = 0.03), likely due to test-retest phenomenon. CONCLUSIONS: PVT reaction time slowed significantly immediately post-chemotherapy compared to a pre-chemotherapy baseline, and levels of impairment similar to effects of alcohol consumption in other studies was seen in 40% of patients. Further studies assessing functional impact of cognitive impairment on patients immediately after chemotherapy are warranted.

Impact of Cumulative Chemotherapy Dose on Survival With Adjuvant FEC-D Chemotherapy for Breast Cancer.

BACKGROUND: Reductions in adjuvant chemotherapy dose <85% for historical regimens (ie, cyclophosphamide/methotrexate/fluorouracil) are known to affect breast cancer survival. This threshold, in addition to early versus late dose reductions, are poorly defined for third-generation anthracycline/taxane-based chemotherapy. In patients with breast cancer receiving adjuvant 5-fluorouracil/epirubicin/cyclophosphamide followed by docetaxel (FEC-D), we evaluated the impact of chemotherapy total cumulative dose (TCD), and early (FEC) versus late (D only) dose reductions, on survival outcomes. PATIENTS AND METHODS: Women with stage I-III, hormone receptor-positive/negative, HER2-negative breast cancer treated with adjuvant FEC-D chemotherapy from 2007 through 2014 in Alberta, Canada, were included. TCD for cycles 1 to 6 of <85% or ≥85% was calculated. Average cumulative dose was also calculated for early (cycles 1-3) and late (cycles 4-6) chemotherapy. Survival outcomes (disease-free survival [DFS] and overall survival [OS]) were estimated using Kaplan-Meier and multivariate analysis. Cohorts were evaluated for uniformity. RESULTS: Characteristics were reasonably balanced for all cohorts. Overall, 1,302 patients were evaluated for dose reductions, with 16% being reduced <85% (n=202) relative to ≥85% (n=1,100; 84%). Patients who received TCD ≥85% relative to <85% had superior 5-year DFS (P=.025) and OS (P<.001) according to Kaplan-Meier analysis, which remained significant on univariate and multivariate analyses. In stratified late and early dose reduction cohorts, DFS and OS showed a significant inferior survival trend for dose reduction early in treatment administration in 5-year Kaplan-Meier (P=.002 and P<.001, respectively) and multivariate analyses (hazard ratio [HR], 1.46; P=.073, and HR, 1.77; P=.011, respectively). Dose delays of <14 or ≥14 days and granulocyte colony-stimulating factor use did not affect outcomes. CONCLUSIONS: Chemotherapy TCD <85% for adjuvant FEC-D affects breast cancer survival. Late reductions (D only) were not shown to adversely affect DFS or OS. Conversely, early reductions (FEC±D) negatively affected patient outcomes.

Baxter elastomeric pumps: Weighing as an alternative to visual inspection.

Purpose Elastomeric pumps are used to administer 46-hour infusions of 5-fluorouracil (5FU). Baxter suggests patients visually monitor their pumps to ensure that infusions are proceeding correctly. This can be confusing and lead to concerns about under- or over-dosing. Baxter has not considered weighing pumps as a validated method for monitoring. This study aims to validate weighing as a more accurate method for patients and healthcare professionals, and describe real life Baxter Infusor™ variability. Methods Patients who had been started on a 46-hour 5FU infusion returned to the clinic approximately 24 h after starting treatment. The pump was weighed on a StarFrit kitchen scale, and date, time, and weights recorded. Patients were asked if they had a preference for weighing or visually inspecting their pump. Results Pumps ( n = 103) were weighed between 17.25 and 27.5 h after connection. The average weight of a pump was 189 g. Of 103 pumps weighed, 99 weighed less than expected, corresponding to average flow rates of 5.69 mL/h over the elapsed time. The expected flow rate is 5 mL/h with 10% variability. Average flow rates within the 17.25- to 27.5-hour window were 4.561 mL/h, which is 8.78% slower than expected, but within the 10% known variability. Forty-seven percent of patients didn't have a preference for either method, but for those who did have a preference, more than twice as many preferred weighing. Conclusion With proper education, weighing Baxter Infusors at home with kitchen scales can be an accepted and objective alternative to the current recommendation of visual inspection.

Drug development for breast, colorectal, and non-small cell lung cancers from 1979 to 2014.

BACKGROUND: Understanding the drug development pathway is critical for streamlining the development of effective cancer treatments. The objective of the current study was to delineate the drug development timeline and attrition rate of different drug classes for common cancer disease sites. METHODS: Drugs entering clinical trials for breast, colorectal, and non-small cell lung cancer were identified using a pharmaceutical business intelligence database. Data regarding drug characteristics, clinical trials, and approval dates were obtained from the database, clinical trial registries, PubMed, and regulatory Web sites. RESULTS: A total of 411 drugs met the inclusion criteria for breast cancer, 246 drugs met the inclusion criteria for colorectal cancer, and 315 drugs met the inclusion criteria for non-small cell lung cancer. Attrition rates were 83.9% for breast cancer, 87.0% for colorectal cancer, and 92.0% for non-small cell lung cancer drugs. In the case of non-small cell lung cancer, there was a trend toward higher attrition rates for targeted monoclonal antibodies compared with other agents. No tumor site-specific differences were noted with regard to cytotoxic chemotherapy, immunomodulatory, or small molecule kinase inhibitor drugs. Drugs classified as "others" in breast cancer had lower attrition rates, primarily due to the higher success of hormonal medications. Mean drug development times were 8.9 years for breast cancer, 6.7 years for colorectal cancer, and 6.6 years for non-small cell lung cancer. CONCLUSIONS: Overall oncologic drug attrition rates remain high, and drugs are more likely to fail in later-stage clinical trials. The refinement of early-phase trial design may permit the selection of drugs that are more likely to succeed in the phase 3 setting. Cancer 2017;123:4672-4679. © 2017 American Cancer Society.

The Evolution of Metastatic Colorectal Cancer Clinical Trials: Application of the ASCO Framework for Assessing Value.

Background: Phase III trials in metastatic colorectal cancer (mCRC) have collectively led to progressive advancements in patient outcomes over the past decades. This study characterizes the evolution of mCRC phase III trials through assessing the value of cancer therapy, as measured by the ASCO Value Framework. Methods: Phase III trial results of systemic therapy for mCRC published between 1980 and 2015 were identified, and their outcome, statistical significance, journal impact factor, and citation by the 2016 NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines) for CRC were recorded. For each trial, the net health benefit (NHB) score was calculated using the June 2015 (original) and May 2016 (revised) ASCO Value Framework: Advanced Disease. Results: There were 114 mCRC phase III trials eligible for calculation of the NHB score. Using the revised framework, the median NHB score was 4.6 (range, -30 to 43.5); 12% of trials received bonus points. Trials with statistically significant results had higher NHB scores compared with nonsignificant trials (median NHB score, 21.6 vs 2.9; P<.0001). Clinical trials cited in the NCCN Guidelines had higher NHB scores than those not cited (median score, 8.0 vs 0.3; P=.02). In multivariate linear regression analysis, the only significant predictor of high NHB score was statistically significant studies. Conclusions: The median NHB score for mCRC phase III trials was 4.6. Higher NHB scores are associated with statistically significant studies and are cited in the NCCN Guidelines, a surrogate for practice-changing trials. The 2016 ASCO Value Framework may not fully capture the benefits on an individual patient level.

Baxter elastomeric pumps: Feasibility of weight estimates.

Purpose Elastomeric pumps are used to infuse a 46-h fluorouracil protocol and patients are asked to visually inspect the pump daily. The pump has a variability of ±10% and there are additional patient variables that can increase this. The feasibility of weighing the pump rather than a visual inspection along with the secondary objective to confirm the pump's variability in real world conditions was undertaken. Methods Empty pumps were weighed using both pharmacy and kitchen scales. Pumps upon completion of the 46-h infusion were also weighed using both pharmacy and kitchen scales. Results The kitchen scale was as accurate as the pharmacy grade scale. Disconnected pumps showed the expected variability from using these infusor pumps along with a few showing greater variability likely due to patient variables. Conclusion Weighing pumps appears to be feasible both at the pharmacy and home level. Next steps would be to weigh pumps during the infusion to validate an alternate method to simple visual inspection for patients to confirm proper infusing of the pump at their home.

Media Reporting of Practice-Changing Clinical Trials in Oncology: A North American Perspective.

INTRODUCTION: Media reporting of clinical trials impacts patient-oncologist interactions. We sought to characterize the accuracy of media and Internet reporting of practice-changing clinical trials in oncology. MATERIALS AND METHODS: The first media articles referencing 17 practice-changing clinical trials were collected from 4 media outlets: newspapers, cable news, cancer websites, and industry websites. Measured outcomes were media reporting score, social media score, and academic citation score. The media reporting score was a measure of completeness of information detailed in media articles as scored by a 15-point scoring instrument. The social media score represented the ubiquity of social media presence referencing 17 practice-changing clinical trials in cancer as determined by the American Society of Clinical Oncology in its annual report, entitled Clinical Cancer Advances 2012; social media score was calculated from Twitter, Facebook, and Google searches. The academic citation score comprised total citations from Google Scholar plus the Scopus database, which represented the academic impact per clinical cancer advance. RESULTS: From 170 media articles, 107 (63%) had sufficient data for analysis. Cohen's κ coefficient demonstrated reliability of the media reporting score instrument with a coefficient of determination of 94%. Per the media reporting score, information was most complete from industry, followed by cancer websites, newspapers, and cable news. The most commonly omitted items, in descending order, were study limitations, exclusion criteria, conflict of interest, and other. The social media score was weakly correlated with academic citation score. CONCLUSION: Media outlets appear to have set a low bar for coverage of many practice-changing advances in oncology, with reports of scientific breakthroughs often omitting basic study facts and cautions, which may mislead the public. The media should be encouraged to use a standardized reporting template and provide accessible references to original source information whenever feasible.

Adult patient perspectives on clinical trial result reporting: A survey of cancer patients.

BACKGROUND: The provision of study results to research participants is supported by pediatric and adult literature. This study assessed adult cancer patient preferences surrounding aggregate result disclosure to study participants. METHODS: A 46-item questionnaire was given to 250 adult cancer patients who had participated in oncology trials at a single center. Respondents answered questions surrounding their preferences for timing, content, and modality of communication for dissemination of study results. RESULTS: Questionnaire completion rate was 76% (189/250). Most patients (92%) strongly felt a right to know study results. Patients preferred result dissemination via letter for trials with positive outcomes, but preferred in-person clinic visits for negative outcomes. Despite this, a majority of participants (59%) found letters acceptable to inform participants of negative results. Only a minority (36%) of the participants found Internet-based disclosure acceptable for negative trial results. Unfortunately, very few patients (8%) recalled having received the results for a study they participated in, and of these patients, less than half fully understood the results they were given. CONCLUSION: Most clinical trial participants feel they have a right to study result disclosure, regardless of trial outcome. In-person visits are preferred for negative results, but more feasible alternatives such as letters were still acceptable for the majority of participants. However, Internet-based disclosure was not acceptable to most participants in oncology trials. Time and cost allocations for result disclosure should be considered during grant and ethics board applications, and clear guidelines are required to help researchers share the results with patients.

Comparison of oncology drug approval between Health Canada and the US Food and Drug Administration.

BACKGROUND: The drug approval timeline is a lengthy process that often varies between countries. The objective of this study was to delineate the Canadian drug approval timeline for oncology drugs and to compare the time to drug approval between Health Canada (HC) and the US Food and Drug Administration (FDA). METHODS: In total, 54 antineoplastic drugs that were approved by the FDA between 1989 and 2012 were reviewed. For each drug, the following milestones were determined: the dates of submission and approval for both the FDA and HC and the dates of availability on provincial drug formularies in Canadian provinces and territories. The time intervals between the aforementioned milestones were calculated. RESULTS: Of 54 FDA-approved drugs, 49 drugs were approved by HC at the time of the current study. The median time from submission to approval was 9 months (interquartile range [IQR], 6-14.5 months) for the FDA and 12 months (IQR, 10-21.1 months) for HC (P < .0006). The time from HC approval to the placement of a drug on a provincial drug formulary was a median of 16.7 months (IQR, 5.9-27.2 months), and there was no interprovincial variability among the 5 Canadian provinces that were analyzed (P = .5). CONCLUSIONS: The time from HC submission to HC approval takes 3 months longer than the same time interval for the FDA. To the authors' knowledge, this is the first documentation of the time required to bring an oncology drug from HC submission to placement on a provincial drug formulary.

Colorectal Cancer Patients' Reported Frequency, Content, and Satisfaction with Advance Care Planning Discussions.

(1) Background: This observational cohort study describes the frequency, content, and satisfaction with advance care planning (ACP) conversations with healthcare providers (HCPs), as reported by patients with advanced colorectal cancer. (2) Methods: The patients were recruited from two tertiary cancer centers in Alberta, Canada. Using the My Conversations survey with previously validated questions, the patients were asked about specific ACP elements discussed, with which HCPs these elements were discussed, their satisfaction with these conversations, and whether they had a goals of care designation (GCD) order. We surveyed and analyzed data from the following four time points: enrollment, months 1, 2, and 3. (3) Results: In total, 131 patients were recruited. At enrollment, 24% of patients reported discussing at least one ACP topic. From enrollment to month 3, patients reported a high frequency of discussions (80.2% discussed fears, 71.0% discussed prognosis, 54.2% discussed treatment preferences at least once); however, only 44.3% of patients reported discussing what is important to them in considering health care preferences. Patients reported having ACP conversations most often with their oncologists (84.7%) and cancer clinic nurses (61.8%). Patients reported a high level of satisfaction with their ACP conversations, with over 80% of patients reported feeling heard and understood. From enrollment to month 3, there was an increase in the number of patients with a GCD order from 53% to 74%. (4) Conclusions: Patients reported more frequent conversations compared to the literature and clinical documentation. While the satisfaction with these conversations is high, there is room for quality improvement, particularly in eliciting patients' personal goals for their treatment.

Programmed death 1 pathway inhibition in metastatic renal cell cancer and prostate cancer.

Programmed death 1 (PD-1) is a T cell co-inhibitory receptor with two ligands, PD-L1 and PD-L2. In cancer, this pathway plays a major role in immune resistance in the tumor environment. Blockade of this pathway can enhance antitumor immune responses. This review discusses the preclinical rationale for PD-1 pathway inhibition in advanced renal cell carcinoma and prostate cancer, in addition to the clinical activity and toxicity of the anti-PD-L1 antibody BMS-936559, as well as anti-PD-1 antibodies MK-3475 and BMS-936558.

Navigating the Cancer Journey Using Web-Based Information: Grounded Theory Emerging From the Lived Experience of Cancer Patients and Informal Caregivers With Implications for Web-Based Content Design.

BACKGROUND: The internet is an important source of information for many informal caregivers and patients living with cancer. A better understanding of how individuals use the internet to meet their informational needs is important for guiding intervention development. OBJECTIVE: The objectives of this study were to develop a theory describing why individuals living with cancer use the internet to find information, characterize the challenges faced with existing web-based content, and provide recommendations for web-based content design. METHODS: Adults (≥18 years) with a history of being patients with cancer or informal caregivers were recruited from Alberta, Canada. After providing informed consent, participants were engaged through digitally recorded one-on-one semistructured interviews, focus groups, a web-based discussion board, and emails. Classic grounded theory guided the study procedures. RESULTS: A total of 21 participants took part in 23 one-on-one interviews and 5 focus groups. The mean age was 53 (SD 15.3) years. Breast, gynecological, and hematological cancers were the most common cancer types (4/21, 19% each). In total, 67% (14/21) of patients, 29% (6/21) of informal caregivers, and 5% (1/21) of individuals reporting both roles participated. Participants experienced many new challenges in their cancer journey and used the internet to become better oriented to them. For each challenge, internet searching attempted to address one or more of 3 key orientation questions: why the challenge was happening, what to expect, and options for managing it. Better orientation resulted in improved physical and psychosocial well-being. Content that was well laid out, concise, free of distractions, and that addressed the key orientation questions was identified as the most helpful in assisting with orientation. Creators of web-based content are encouraged to 1) clearly identify the cancer challenge and population the content is addressing, as well as the presence of any potentially distressing information; 2) provide versions of the content in different formats, including printer-friendly, audio, video, and alternative languages; 3) state who created the content, including the individuals, organizations, and processes involved; 4) place hyperlinks after the key orientation questions have been addressed; and 5) ensure that the content is optimized for discovery by search engines (ie, Google). CONCLUSIONS: Web-based content plays an essential role for many living with cancer. Clinicians are encouraged to take active steps to help patients and informal caregivers find web-based content that meets their informational needs. Content creators also have a responsibility to ensure that the content they create assists and does not hinder those navigating the cancer journey. Research is needed to better understand the many challenges that individuals living with cancer face, including how they are temporally related. In addition, how to optimize web-based content for specific cancer challenges and populations should be considered an important area for future research.

Clinical and metabolomic characterization of Brivanib-Induced hypertension in metastatic colorectal cancer.

BACKGROUND: Trials of tyrosine kinase inhibitors (TKI) have not demonstrated dramatic benefits in advanced colorectal cancer (CRC), and this may be a function of poor patient selection. TKI-induced hypertension is reportedly a surrogate marker for treatment benefit for some tumor types. Our objective was to determine whether hypertension was associated with benefit in the context of CRC treatment, and also to gain insight on the pathogenesis of TKI-induced hypertension by monitoring associated changes in the circulating metabolome. PATIENTS AND METHODS: Clinical data were acquired from clinical trial patients with metastatic CRC randomized to cetuximab ± the TKI brivanib (N = 750). Outcomes were evaluated as a function of treatment-induced hypertension. For metabolomic studies, plasma samples were taken at baseline, as well as at 1, 4, and 12 weeks after treatment initiation. Samples were submitted to gas chromatography-mass spectrometry to identify treatment-related metabolomic changes associated with TKI-induced hypertension, compared to pre-treatment baseline. A model based on changes in metabolite concentrations was generated using orthogonal partial least squares discriminant analysis (OPLS-DA). RESULTS: In the brivanib treated group, 95 patients had treatment-related hypertension within 12 weeks of initiating treatment. TKI-induced hypertension was not associated with a significantly higher response rate, nor was it associated with improved progression-free or overall survival. In metabolomic studies, 386 metabolites were identified. There were 29 metabolites that changed with treatment and distinguished patients with and without TKI-induced hypertension. The OPLS-DA model for brivanib-induced hypertension was significant and robust (R2 Y score = 0.89, Q2 Y score = 0.70, CV-ANOVA = 2.01 e-7). Notable metabolomic features previously reported in pre-eclampsia and associated with vasoconstriction were found. CONCLUSION: TKI-induced hypertension was not associated with clinical benefit in metastatic CRC. We have identified changes in the metabolome that are associated with the development of worsening brivanib-induced hypertension that may be useful in future efforts of characterizing this toxicity.

A phase II study of the halichondrin B analog eribulin mesylate in gemcitabine refractory advanced pancreatic cancer.

BACKGROUND: Eribulin mesylate is a halichondrin B analog that inhibits microtubule dynamics. Pre-clinical studies have suggested anti-tumor activity in pancreatic cancer. This phase II study of eribulin in patients with advanced pancreatic cancer previously treated with gemcitabine was conducted by the Princess Margaret Hospital Phase II consortium. PATIENTS AND METHODS: Eligibility criteria included locally advanced or metastatic pancreatic adenocarcinoma and previous treatment with gemcitabine. The study was a single arm phase II trial using a Simon 2-stage design. The primary endpoint was response rate, secondary endpoints included time to progression and overall survival. RESULTS: Fifteen patients were enrolled, 14 received treatment, and 12 were evaluable for response. The median age was 61, and the majority of patients were ECOG performance status 1. Grade 3 or greater adverse events included neutropenia (29%), fatigue (14%), peripheral neuropathy (7%) and thrombosis (7%). There were no complete or partial responses and therefore the study was closed after the first stage. The best response was stable disease in 5/12 (42%) of patients. Of these five patients, three had stable disease for 9 months or greater. Median time to progression was 1.4 months, and median overall survival was 6.1 months. CONCLUSION: Eribulin was well tolerated but did not result in any objective responses in gemcitabine refractory pancreatic cancer. However, several patients had prolonged stable disease, suggesting that further studies of eribulin in pancreatic cancer may be warranted.
