The Influence of Supportive Oncodermatology Interventions on Patient Quality of Life: A Cross-Sectional Survey

BACKGROUND

Dermatologic adverse events (dAEs) secondary to anticancer treatments reduce patients’ quality of life (QOL) and result in interruptions in anticancer therapy.

OBJECTIVE

Determine if a comprehensive supportive oncodermatology program improves patients’ QOL scoring.

METHODS

This was a cross-sectional survey of adult cancer patients enrolled in the George Washington University Supportive Oncodermatology Clinic. All patients were above age 18 years and received dermatologic care between May 1, 2017 and November 1, 2019. Fifty-five patents meeting inclusion criteria were invited to complete an online survey with questions adapted from the Dermatology Life Quality Index (DLQI) and Patient Satisfaction Questionnaire (PSQ-18).

RESULTS

Survey initiation rate was 61.8% (34/55) and completion rate 88.2% (30/34). Average QOL score prior to treatment was 6.5 (moderate effect on QOL) and 3.8 (small effect) afterwards (P=0.0005; 95% CI -3.9 to -1.). Average satisfaction score was 4.15 ± 0.7 (satisfied). Impact on treatment adherence earned the lowest score (3.67, neutral to satisfied).

LIMITATIONS

Recall bias Conclusion: Enrollment was significantly associated with improved QOL. Dermatologic care also resulted in overall satisfied patient outcomes, although many patients were unsure if these dermatologic interventions aided in anticancer treatment adherence, highlighting the need for evidence-based management strategies for dAEs.

A catalyst for transforming health systems and person-centred care: Canadian national position statement on patient-reported outcomes

Background

Patient-reported outcomes (pros) are essential to capture the patient's perspective and to influence care. Although pros and pro measures are known to have many important benefits, they are not consistently being used and there is there no Canadian pros oversight. The Position Statement presented here is the first step toward supporting the implementation of pros in the Canadian health care setting.

Methods

The Canadian pros National Steering Committee drafted position statements, which were submitted for stakeholder feedback before, during, and after the first National Canadian Patient Reported Outcomes (canpros) scientific conference, 14-15 November 2019 in Calgary, Alberta. In addition to the stakeholder feedback cycle, a patient advocate group submitted a section to capture the patient voice.

Results

The canpros Position Statement is an outcome of the 2019 canpros scientific conference, with an oncology focus. The Position Statement is categorized into 6 sections covering 4 theme areas: Patient and Families, Health Policy, Clinical Implementation, and Research. The patient voice perfectly mirrors the recommendations that the experts reached by consensus and provides an overriding impetus for the use of pros in health care.

Conclusions

Although our vision of pros transforming the health care system to be more patient-centred is still aspirational, the Position Statement presented here takes a first step toward providing recommendations in key areas to align Canadian efforts. The Position Statement is directed toward a health policy audience; future iterations will target other audiences, including researchers, clinicians, and patients. Our intent is that future versions will broaden the focus to include chronic diseases beyond cancer.

Recommendations for spiritual care in cancer patients: a clinical practice guideline for oncology nurses in Iran

BACKGROUND

In spite of the necessity of implementing spiritual care practices for cancer patients, there is no clear process in this regard in palliative care programs of the health system of countries. The present study was designed with the aim of developing a clinical practice guideline of spiritual care in cancer patients for oncology nurses in the current context.

METHODS

This is a multi-method study which was conducted in five stages within the framework of the National Institute for Health and Care Excellence (NICE) guideline. A research committee consisting of four focal and 16 secondary members was formed. The stages included determining the scope of the study, developing guideline (a qualitative study and a systematic review, triangulation of the data, and producing a preliminary draft), consultation stage (validation of the guideline in three rounds of the Delphi study), as well as revision and publication stages.

RESULTS

The clinical guideline of spiritual care with 84 evidence-based recommendations was developed in three main areas, including the human resources, care settings, and the process of spiritual care.

CONCLUSIONS

We are hoping by applying this clinical guideline in oncology settings to move towards an integrated spiritual care plan for cancer patients in the context of our health system. Healthcare organizations should support to form spiritual care teams under supervision of the oncology nurses with qualified healthcare providers and a trained clergy. Through holistic care, they can constantly examine the spiritual needs of cancer patients alongside their other needs by focusing on the phases of the nursing process.

Micro RNA Molecules as Modulators of Treatment Resistance, Immune Checkpoints Controllers and Sensitive Biomarkers in Glioblastoma Multiforme

Based on genome sequencing, it is estimated that over 90% of genes stored in human genetic material are transcribed, but only 3% of them contain the information needed for the production of body proteins. This group also includes micro RNAs representing about 1%–3% of the human genome. Recent studies confirmed the hypothesis that targeting molecules called Immune Checkpoint (IC) open new opportunities to take control over glioblastoma multiforme (GBM). Detection of markers that indicate the presence of the cancer occupies a very important place in modern oncology. This function can be performed by both the cancer cells themselves as well as their components and other substances detected in the patients’ bodies. Efforts have been made for many years to find a suitable marker useful in the diagnosis and monitoring of gliomas, including glioblastoma.

Development of a core information set for colorectal cancer surgery: a consensus study

OBJECTIVE

'Core information sets' (CISs) represent baseline information, agreed by patients and professionals, to stimulate individualised patient-centred discussions. This study developed a CIS for use before colorectal cancer (CRC) surgery.

DESIGN

Three phase consensus study: (1) Systematic literature reviews and patient interviews to identify potential information of importance to patients, (2) UK national Delphi survey of patients and professionals to rate the importance of the information, (3) international consensus meeting to agree on the final CIS.

SETTING

UK CRC centres.

PARTICIPANTS

Purposive sampling was conducted to ensure CRC centre representation based upon geographical region and caseload volume. Responses were received from 63/81 (78%) centres (90 professionals). Adult patients who had undergone CRC surgery were eligible, and purposive sampling was conducted to ensure representation based on age, sex and cancer location (rectum, left and right colon). Responses were received from 97/267 (35%) patients with a wide age range (29-87), equal sex ratio and cancer location. Attendees of the international Tripartite Colorectal Conference were eligible for the consensus meeting.

OUTCOMES

Phase 1: Information of potential importance to patients was extracted verbatim and operationalised into a Delphi questionnaire. Phase 2: Patients and professionals rated the importance information on a 9-point Likert scale, and resurveyed following group feedback. Information rated of low importance were discarded using predefined criteria. Phase 3: A modified nominal group technique was used to gain final consensus in separate consensus meetings with patients and professionals.

RESULTS

Data sources identified 1216 pieces of information that informed a 98-item questionnaire. Analysis led to 50 and 23 information domains being retained after the first and second surveys, respectively. The final CIS included 11 concepts including specific surgical complications, short and long-term survival, disease recurrence, stoma and quality of life issues.

CONCLUSIONS

This study has established a CIS for professionals to discuss with patients before CRC surgery.

Tumor Board Conferences for Multidisciplinary Skin Cancer Management: A Survey of US Cancer Centers

Background: Tumor board conferences (TBCs) are used by oncologic specialists to review patient cases, exchange knowledge, and discuss options for cancer management. These multidisciplinary meetings are often a cornerstone of treatment at leading cancer centers and are required for accreditation by certain groups, such as the American College of Surgeons' Commission on Cancer. Little is known regarding skin cancer TBCs. The objective of this study was to characterize the structure, function, and impact of existing skin cancer TBCs in the United States. Methods: A cross-sectional online survey was administered to physician leaders of skin cancer TBCs at NCI-designated Comprehensive and Clinical Cancer Centers. Results: Of the 59 centers successfully contacted, 14 (24%) reported not having a conference where skin cancer cases were discussed, and 45 (76%) identified 53 physician leaders. A total of 38 physicians (72%) completed the survey. Half of the meeting leaders were medical and/or surgical oncologists, and dermatologists led one-third of meetings. TBCs had a moderate to significant impact on patient care according to 97% of respondents. All respondents indicated that the meetings enhanced communication among physicians and provided an opportunity for involved specialists and professionals to discuss cases. The most frequently cited barrier to organizing TBCs was determining a common available date and time for attendees (62%). The most common suggestion for improvement was to increase attendance, specialists, and/or motivation. Conclusions: Results showed overall consistency in meeting structure but variability in function, which may be a reflection of institutional resources and investment in the conference. Future directions include defining metrics to evaluate changes in diagnosis or management plan after tumor board discussion, attendance, clinical trial enrollment, and cost analysis. Results of this survey may aid other institutions striving to develop and refine skin cancer TBCs.

Understanding Long-Term Cancer Survivors' Preferences for Ongoing Medical Care

BACKGROUND

Due to risk for treatment-related late effects and concerns about cancer recurrence, long-term cancer survivors have unique medical needs. Survivors' preferences for care may influence adherence and care utilization.

OBJECTIVE

To describe survivors' preferences for care and factors associated with preferred and actual care.

DESIGN

Cross-sectional analysis of participants in a longitudinal study using mailed questionnaires.

PARTICIPANTS

Survivors of ten common cancers (n = 2,107, mean years from diagnosis 8.9).

MAIN MEASURES

(1) Survivors' preferences for primary care physician (PCP) and oncologist responsibilities across four types of care: cancer follow-up, cancer screening, preventive health, and comorbid conditions. (2) Survivor-reported visits to PCPs and oncologists.

KEY RESULTS

The response rate was 42.1%. Most long-term survivors preferred PCPs and oncologists share care for cancer follow-up (63%) and subsequent screening (65%), while preferring PCP-led preventive health (77%) and comorbid condition (83%) care. Most survivors (88%) preferred oncologists involved in cancer follow-up care, but only 60% reported an oncologist visit in the previous 4 years, and 96% reported a PCP visit in the previous 4 years. In multivariable regressions, those with higher fear of cancer recurrence were less likely to prefer PCP-led cancer follow-up care (OR = 0.96, CI = 0.93-0.98), as did survivors with advanced cancer stage (OR = 0.56, CI = 0.39-0.79). Those with higher fear of recurrence (OR = 1.03, CI = 1.01-1.04) or who preferred oncologist-led cancer follow-up care (OR = 2.08, CI = 1.63-2.65) had greater odds of seeing an oncologist in the last 4 years.

CONCLUSIONS

Most cancer survivors preferred PCPs and oncologists share care for cancer follow-up and screening, yet many had not seen an oncologist recently. Survivors preferred PCP-led care for other preventive services and management of comorbid conditions. These findings highlight the important role PCPs could play in survivor care, suggesting the need for PCP-oriented education and health system policies that support high-quality PCP-led survivor care.

[Should older patients with cancer visit a geriatrician as well? The value of geriatric assessments]

The value of geriatric assessments The ASCO guideline for Geriatric Oncology recommends submitting older patients with cancer to a geriatric assessment. Although we recognise the importance of awareness of geriatric problems in older patients with cancer, this approach where two different doctors are treating the same patient is not ideal for several reasons. We therefore recommend educating medical oncologists on geriatric problems, aging and different treatment goals.

A Multicenter Comparison of Complementary and Alternative Medicine (CAM) Discussions in Oncology Care: The Role of Time, Patient-Centeredness, and Practice Context

BACKGROUND

Little is known about how complementary and alternative medicine (CAM) is discussed in cancer care across varied settings in the U.S.

METHODS

In two practices affiliated with one academic medical center in southern California (SoCal), and one in the upper Midwest (UM), we audio-recorded patient-clinician interactions in medical oncology outpatient practices. We counted the frequency and duration of CAM-related conversations. We coded recordings using the Roter Interaction Analysis System. We used chi-square tests for bivariate analysis of categorical variables and generalized linear models for continuous variables to examine associations between dialogue characteristics, practice setting, and population characteristics with the occurrence of CAM discussion in each setting followed by multivariate models adjusting for clinician clustering.

RESULTS

Sixty-one clinicians and 529 patients participated. Sixty-two of 529 (12%) interactions included CAM discussions, with significantly more observed in the SoCal university practice than in the other settings. Visits that included CAM were on average 6 minutes longer, with CAM content lasting an average of 78 seconds. In bivariate tests of association, conversations containing CAM included more psychosocial statements from both clinicians and patients, higher patient-centeredness, more positive patient and clinician affect, and greater patient engagement. In a multivariable model including significant bivariate terms, conversations containing CAM were independently associated with higher patient-centeredness, slightly longer visits, and being at the SoCal university site.

CONCLUSION

The frequency of CAM-related discussion in oncology varied substantially across sites. Visits that included CAM discussion were longer and more patient centered.

IMPLICATIONS FOR PRACTICE

The Institute of Medicine and the American Society of Clinical Oncology have called for more open discussions of complementary and alternative medicine (CAM). But little is known about the role population characteristics and care contexts may play in the frequency and nature of those discussions. The present data characterizing actual conversations in practice complements a much larger literature based on patient and clinician self-report about CAM disclosure and use. It was found that CAM discussions in academic oncology visits varied significantly by practice context, that the majority were initiated by the patient, and that they may occur more when visit time exists for lifestyle, self-care, and psychosocial concerns.

Association of Industry and Academic Sponsorship With Negative Phase 3 Oncology Trials and Reported Outcomes on Participant Survival: A Pooled Analysis

Importance

Only 3.4% of cancer drugs evaluated in phase 1 trials are approved by the US Food and Drug Administration, with most failing in phase 3 trials.

Objective

To investigate whether an association exists between the sponsorship and conduct of a negative phase 3 randomized clinical trial (RCT) investigating a cancer drug that lacked supporting phase 2 trial evidence for that drug, and to evaluate the association with overall survival among patients randomized to the experimental arm of such phase 3 trials.

Data Sources

Articles in the Lancet, Lancet Oncology, JAMA, JAMA Oncology, and Journal of Clinical Oncology published between January 2016 and June 2018 were searched.

Study Selection

Phase 3 RCTs of cancer drugs that failed to improve the primary end point were selected and any prior phase 2 trial of the same drug that supported the phase 3 trial was selected without any date or journal restrictions.

Data Extraction and Synthesis

Percentages of negative phase 3 RCTs of cancer drugs that lacked any phase 2 evidence, had a negative phase 2 trial, or had a positive phase 2 study were extracted. Associations were assessed using the Fisher exact test. Pooled hazard ratios and 95% CIs for the overall survival of patients enrolled in these negative phase 3 RCTs were estimated using a random-effects model.

Main Outcomes and Measures

Negative phase 3 RCTs with a lack of a phase 2 trial or the presence of a negative phase 2 trial and overall survival of enrolled patients in the phase 3 RCTs.

Results

In this meta-epidemiological study, 67 negative phase 3 RCTs on cancer drugs, which included 64 600 patients, met the criteria of being sponsored by industry or academic groups, of which 42 RCTs (63%) were industry sponsored and the remaining 25 RCTs (37%) were academic. A phase 2 trial was not available for 28 of these trials (42%). Of 29 trials (43%) with a phase 2 trial available, 8 trials (28%) failed to meet their primary end points and 5 of those were industry sponsored. There was no association with overall survival for patients participating in these negative phase 3 RCTs (pooled hazard ratio, 0.99; 95% CI, 0.96-1.02). When the pooled analysis was limited to the 27 RCTs with a hazard ratio above 1.00, the overall pooled hazard ratio for overall survival was 1.11 (95% CI, 1.06-1.16). No association between having a negative or undefined phase 2 trial and trial sponsorship was found using the Fisher exact test.

Conclusions and Relevance

More than 40% of the negative phase 3 RCTs in oncology published in these 5 journals were conducted without a supporting phase 2 trial and were sponsored by both academia and industry. Running such trials not only may risk loss of resources owing to a failed trial but also may be associated with decreased patient survival. Further research and regulations in this area appear warranted.

Meeting report from the joint IARC-NCI international cancer seminar series: a focus on colorectal cancer

Despite significant progress in our understanding of the etiology, biology and genetics of colorectal cancer, as well as important clinical advances, it remains the third most frequently diagnosed cancer worldwide and is the second leading cause of cancer death. Based on demographic projections, the global burden of colorectal cancer would be expected to rise by 72% from 1.8 million new cases in 2018 to over 3 million in 2040 with substantial increases anticipated in low- and middle-income countries. In this meeting report, we summarize the content of a joint workshop led by the National Cancer Institute and the International Agency for Research on Cancer, which was held to summarize the important achievements that have been made in our understanding of colorectal cancer etiology, genetics, early detection and treatment and to identify key research questions that remain to be addressed.

Reasons for complementary therapy use by cancer patients, information sources and communication with health professionals

BACKGROUND

Cancer patients are known to commonly use complementary therapies (CT). However, it is emphasized that patients do not share sufficient information with health professionals about this subject and that the subject is ignored in oncology practice. The aim of the study is to assess cancer patients' reasons for using complementary therapy, information resources and communication with health professionals.

METHODS

The study is a descriptive, cross-sectional study. In this study, a questionnaire was used by the researchers. A questionnaire form consisting of 3 parts was used. In the first part of this form, there were questions about the gender, age and educational status of the patients (8 questions). In the second part, there were questions about disease and treatment information (3 questions), and the third part had questions about the use of complementary therapies (9 questions). To determine the use of complementary therapy, patients were asked 'Do you currently use complementary treatment?' (Yes or No). 183 patients included in the study completed the questionnaire about complementary therapies.

RESULTS

In this study, it was determined that 37.7% of the patients were using complementary therapies. The most commonly used complementary therapy was natural products (46.4%). The most common reason for using complementary therapy was to provide support for treatment. Almost half of the cancer patients (48.5%) did not talk about this issue with their physicians, and 41.1% of them did not talk about CT with their nurses. The study found that the most important reason why the patients did not talk about CT was that they were not asked about it by health professionals.

CONCLUSION

This study determined that almost half of patients could not receive information about CT from health professionals. Patients expect physicians and nurses to initiate communication on this subject. Providing healthcare professionals with evidence-based counseling about CT is essential for improving patient safety and patient outcomes.

Adherence of Mexican physicians to clinical guidelines in the management of breast cancer: Effect of the National Catastrophic Health Expenditure Fund

Aim

To assess the adherence of physicians to the Medical-Care Guidelines for Malignant Breast Tumors in Mexico, before and after the allocation of federal subsidies from the Catastrophic Health Expenditure Fund (FPGC by its Spanish initials) to accredited hospitals, a strategy implemented with the view of offering free treatment to women with breast cancer (BC).

Material and methods

Based on a cross-sectional design, we gathered information on 479 BC patients who had been attended to at in four FPGC-accredited hospitals. Analysis centered on those treated within either three years before or three years after the accreditation of their attending hospitals. The four hospitals analyzed were located in the North, South, West and Center of the country. Information on all medical procedures performed during treatment was drawn from hospital medical records. Information on the socio-demographic characteristics of the patients was obtained by means of face-to-face interviews conducted in their homes.

Results

Adherence of physicians to the Guidelines grew by 12.8 percent (from 43.4 to 56.2 percent) after FPGC accreditation (p<0.001) and varied according to the clinical stage of the disease, with much lower levels of adherence observed in the advanced stages (p<0.05).

Conclusions

The FPGC strategy increased the adherence of physicians to the Medical-Care Guidelines for Malignant Breast Tumors in Mexico.

Evaluating the Strength of the Association Between Industry Payments and Prescribing Practices in Oncology

BACKGROUND

Financial relationships between physicians and the pharmaceutical industry are common, but factors that may determine whether such relationships result in physician practice changes are unknown.

MATERIALS AND METHODS

We evaluated physician use of orally administered cancer drugs for four cancers: prostate (abiraterone, enzalutamide), renal cell (axitinib, everolimus, pazopanib, sorafenib, sunitinib), lung (afatinib, erlotinib), and chronic myeloid leukemia (CML; dasatinib, imatinib, nilotinib). Separate physician cohorts were defined for each cancer type by prescribing history. The primary exposure was the number of calendar years during 2013-2015 in which a physician received payments from the manufacturer of one of the studied drugs; the outcome was relative prescribing of that drug in 2015, compared with the other drugs for that cancer. We evaluated whether practice setting at a National Cancer Institute (NCI)-designated Comprehensive Cancer Center, receipt of payments for purposes other than education or research (compensation payments), maximum annual dollar value received, and institutional conflict-of-interest policies were associated with the strength of the payment-prescribing association. We used modified Poisson regression to control confounding by other physician characteristics.

RESULTS

Physicians who received payments for a drug in all 3 years had increased prescribing of that drug (compared with 0 years), for renal cell (relative risk [RR] 1.81, 95% confidence interval [CI] 1.58-2.07), CML (RR 1.22, 95% CI 1.08-1.39), and lung (RR 1.69, 95% CI 1.58-1.82), but not prostate (RR 0.97, 95% CI 0.93-1.02). Physicians who received compensation payments or >$100 annually had increased prescribing compared with those who did not, but NCI setting and institutional conflict-of-interest policies were not consistently associated with the direction of prescribing change.

CONCLUSION

The association between industry payments and cancer drug prescribing was greatest among physicians who received payments consistently (within each calendar year). Receipt of payments for compensation purposes, such as for consulting or travel, and higher dollar value of payments were also associated with increased prescribing.

IMPLICATIONS FOR PRACTICE

Financial payments from pharmaceutical companies are common among oncologists. It is known from prior work that oncologists tend to prescribe more of the drugs made by companies that have given them money. By combining records of industry gifts with prescribing records, this study identifies the consistency of payments over time, the dollar value of payments, and payments for compensation as factors that may strengthen the association between receiving payments and increased prescribing of that company's drug.

Communicating Risks of Adjuvant Chemotherapy for Breast Cancer: Getting Beyond the Laundry List

PURPOSE

According to the Institute of Medicine, high-quality cancer care should include effective communication between clinicians and patients about the risks and benefits, expected response, and impact on quality of life of a recommended therapy. In the delivery of oncology care, the barriers to and facilitators of communication about potential long-term and late effects, post-treatment expectations, and transition to survivorship care have not been fully defined.

PATIENTS AND METHODS

We collected qualitative data through semistructured interviews with medical oncologists and focus groups with breast cancer survivors and applied the Theoretical Domains Framework to systematically analyze and identify the factors that may influence oncologists' communication with patients with breast cancer about the long-term and late effects of adjuvant therapy.

RESULTS

Eight key informant interviews with medical oncologists and two focus groups with breast cancer survivors provided data. Both oncologists and patients perceived information on long-term effects as valuable in terms of improved clinical communication but had concerns about the feasibility of inclusion before treatment. They described the current approaches to communication of therapy risks as a brief laundry list that emphasized acute adverse effects and minimized more long-term issues. We describe the barriers to communication about potential long-term effects from the perspectives of both groups.

CONCLUSION

This study provides insight into oncologists' communication with patients with breast cancer regarding the potential long-term and late effects of adjuvant chemotherapy and about setting realistic expectations for life after treatment. Opportunities to improve oncologists' communication about the potential toxicities of therapy, particularly regarding long-term and late effects, should be examined further.

Changes in the Use of Comprehensive Geriatric Assessment in Clinical Trials for Older Patients with Cancer over Time

BACKGROUND

The objective of this study was to describe the implementation of comprehensive geriatric assessment (CGA) in clinical trials dedicated to older patients before and after the creation of the International Society of Geriatric Oncology in the early 2000s.

SUBJECTS, MATERIALS, AND METHODS

All phase I, II, and III trials dedicated to the treatment of cancer among older patients published between 2001 and 2004 and between 2011 and 2014 were reviewed. We considered that a CGA was performed when the authors indicated an intention to do so in the Methods section of the article. We collected each geriatric domain assessed using a validated tool even in the absence of a clear CGA, including nutritional, functional, cognitive, and psychological status, comorbidity, comedication, overmedication, social status and support, and geriatric syndromes.

RESULTS

A total of 260 clinical trials dedicated to older patients were identified over the two time periods: 27 phase I, 193 phase II, and 40 phase III trials. CGA was used in 9% and 8% of phase II and III trials, respectively; it was never used in phase I trials. Performance status was reported in 67%, 79%, and 75% of phase I, II, and III trials, respectively. Functional assessment was reported in 4%, 11%, and 13% of phase I, II, and III trials, respectively. Between the two time periods, use of CGA increased from 1% to 11% (p = .0051) and assessment of functional status increased from 3% to 14% (p = .0094).

CONCLUSION

The use of CGA in trials dedicated to older patients increased significantly but remained insufficient.

IMPLICATIONS FOR PRACTICE

This article identifies the areas in which research efforts should be focused in order to offer physicians well-addressed clinical trials with results that can be extrapolated to daily practice.

Are network growth and the contributions to congresses associated with publication success? A pediatric oncology model

BACKGROUND

The consistent focus of 'Advances in Neuroblastoma Research' congresses on the topic neuroblastoma sets it as a model for a circumscribed scientific community.

METHODS

The contributions of authors, institutions and countries to congress abstracts and their collaborations were compared to the Hirsch index (h-index) calculated from the Web of Science publication output on the topic 'neuroblastoma'.

RESULTS

From 1975 to 2016, 18 congresses were held. 8459 authors affiliated to 553 institutions of 53 countries presented 3,993 abstracts. The number of coauthors increased over the years from 2 to 7. A considerable proportion of authors, institutions and countries presented only once (53.7%/25.7%/13.2%). Authors with a high number of abstracts and with a large local network were often among those with a higher publication rate and success (R2 = 0.508 for Pearson's correlation between weight and h-index, R2 = 0.474 for degree centrality, R2 = 0.364 for lobby-index). Closeness and betweenness centralities were less correlated (R2 = 0.127/R2 = 0.33, resp.). The institutions showed a similar impact of local interactions on publication success (degree centrality R2 = 0.417, weight R2 = 0.308), while countries demonstrated a higher correlation of betweenness centrality and h-Index (R2 = 0.704) emphasizing their brokerage role. Of 553 institutions, 520 collaborated within 13 communities and belonged to the large scientific network. 33 satellite institutions had no connections to the central network. They attended 1-4 congresses over a period of 1-16 years.

CONCLUSION

A large scientific network has been developed during the recent 42 years. Growth and interaction at congresses were correlated to publication success. Weight is suggested as a useful and simple estimate.

Production Trends, Collaboration, and Main Topics of the Integrative and Complementary Oncology Research Area: A Bibliometric Analysis

BACKGROUND

The prevalence of cancer has increased over time worldwide. Nevertheless, the number of deaths has been reduced during the past 2 decades. Thus, one-third of the cancer patients are users of complementary and alternative therapies, looking for other types of interventions. The main aim of the present study is to understand the current status of the research in integrative and complementary oncology. Three different aspects were analyzed: production trends, country collaboration, and leading research topics.

METHODS

The dataset was obtained from the documents indexed under the Integrative and Complementary Medicine category of the Web of Science database from 1976 to 2017. VOSviewer and SciMAT software were employed to perform the bibliometric analysis.

RESULTS

The Journal of Ethnopharmacology, China Medical University and the People's Republic of China are the leading producers in the field. Regarding the collaboration, the United States and China present a close connection. The scientific community is focused on the following topics: apoptosis, breast cancer, oxidative stress, chemotherapy, and nuclear factor-Kappa-B (NF-Kappa-B).

CONCLUSIONS

The present article shows potentially important information that allows understanding of the past, present, and future of research in integrative and complementary oncology. It is a useful evidence-based framework on which to base future research actions and academic directions.

[Interconsultation on palliative care for patients with cancer in a general hospital. Features and opportunity]

The international recommendations point to the early integration of palliative care (PC) in cancer through simultaneous care and training of primary teams. The PC Unit of the Hospital General de Agudos E. Tornú conducts interconsultations for hospitalized patients in the hospital and provides training to the treatment teams. The profile of the interconsultations carried out could provide important information about the characteristics of the PC intervention within the institution. The objective of this study was to retrospectively analyze the first-time interconsultations of cancer patients carried out over 2 years, focusing on temporality, identification of problems by the treating team and the PC interconsultation team, the promptness of response and the prognostic capacity of the latter. In the period, 168 interconsultations were carried out. Most patients had advanced disease, poor performance status, no possibility of oncological treatment and recent diagnosis. In approximately 25% of the cases, evidence of early intervention and participation of the pc team in decision making was found. The opportunity of PC intervention is discussed and areas needing improvement are indicated, such as the identification of non-physical symptoms and prognosis, to be considered in future care and educational activities.

Achieving Thoracic Oncology data collection in Europe: a precursor study in 35 Countries

BACKGROUND

A minority of European countries have participated in international comparisons with high level data on lung cancer. However, the nature and extent of data collection across the continent is simply unknown, and without accurate data collection it is not possible to compare practice and set benchmarks to which lung cancer services can aspire.

METHODS

Using an established network of lung cancer specialists in 37 European countries, a survey was distributed in December 2014. The results relate to current practice in each country at the time, early 2015. The results were compiled and then verified with co-authors over the following months.

RESULTS

Thirty-five completed surveys were received which describe a range of current practice for lung cancer data collection. Thirty countries have data collection at the national level, but this is not so in Albania, Bosnia-Herzegovina, Italy, Spain and Switzerland. Data collection varied from paper records with no survival analysis, to well-established electronic databases with links to census data and survival analyses.

CONCLUSION

Using a network of committed clinicians, we have gathered validated comparative data reporting an observed difference in data collection mechanisms across Europe. We have identified the need to develop a well-designed dataset, whilst acknowledging what is feasible within each country, and aspiring to collect high quality data for clinical research.

Applying Artificial Intelligence to Address the Knowledge Gaps in Cancer Care

BACKGROUND

Rapid advances in science challenge the timely adoption of evidence-based care in community settings. To bridge the gap between what is possible and what is practiced, we researched approaches to developing an artificial intelligence (AI) application that can provide real-time patient-specific decision support.

MATERIALS AND METHODS

The Oncology Expert Advisor (OEA) was designed to simulate peer-to-peer consultation with three core functions: patient history summarization, treatment options recommendation, and management advisory. Machine-learning algorithms were trained to construct a dynamic summary of patients cancer history and to suggest approved therapy or investigative trial options. All patient data used were retrospectively accrued. Ground truth was established for approximately 1,000 unique patients. The full Medline database of more than 23 million published abstracts was used as the literature corpus.

RESULTS

OEA's accuracies of searching disparate sources within electronic medical records to extract complex clinical concepts from unstructured text documents varied, with F1 scores of 90%-96% for non-time-dependent concepts (e.g., diagnosis) and F1 scores of 63%-65% for time-dependent concepts (e.g., therapy history timeline). Based on constructed patient profiles, OEA suggests approved therapy options linked to supporting evidence (99.9% recall; 88% precision), and screens for eligible clinical trials on ClinicalTrials.gov (97.9% recall; 96.9% precision).

CONCLUSION

Our results demonstrated technical feasibility of an AI-powered application to construct longitudinal patient profiles in context and to suggest evidence-based treatment and trial options. Our experience highlighted the necessity of collaboration across clinical and AI domains, and the requirement of clinical expertise throughout the process, from design to training to testing.

IMPLICATIONS FOR PRACTICE

Artificial intelligence (AI)-powered digital advisors such as the Oncology Expert Advisor have the potential to augment the capacity and update the knowledge base of practicing oncologists. By constructing dynamic patient profiles from disparate data sources and organizing and vetting vast literature for relevance to a specific patient, such AI applications could empower oncologists to consider all therapy options based on the latest scientific evidence for their patients, and help them spend less time on information "hunting and gathering" and more time with the patients. However, realization of this will require not only AI technology maturation but also active participation and leadership by clincial experts.

Undertreatment of High-Risk Localized Prostate Cancer in the California Latino Population

Background: The NCCN Clinical Practice Guidelines in Oncology recommend definitive therapy for all men with high-risk localized prostate cancer (PCa) who have a life expectancy >5 years or who are symptomatic. However, the application of these guidelines may vary among ethnic groups. We compared receipt of guideline-concordant treatment between Latino and non-Latino white men in California. Methods: California Cancer Registry data were used to identify 2,421 Latino and 8,636 non-Latino white men diagnosed with high-risk localized PCa from 2010 through 2014. The association of clinical and sociodemographic factors with definitive treatment was examined using logistic regression, overall and by ethnicity. Results: Latinos were less likely than non-Latino whites to receive definitive treatment before (odds ratio [OR], 0.79; 95% CI, 0.71-0.88) and after adjusting for age and tumor characteristics (OR, 0.84; 95% CI, 0.75-0.95). Additional adjustment for sociodemographic factors eliminated the disparity. However, the association with treatment differed by ethnicity for several factors. Latino men with no health insurance were considerably less likely to receive definitive treatment relative to insured Latino men (OR, 0.34; 95% CI, 0.23-0.49), an association that was more pronounced than among non-Latino whites (OR, 0.63; 95% CI, 0.47-0.83). Intermediate-versus high-grade disease was associated with lower odds of definitive treatment in Latinos (OR, 0.75; 95% CI, 0.59-0.97) but not non-Latino whites. Younger age and care at NCI-designated Cancer Centers were significantly associated with receipt of definitive treatment in non-Latino whites but not in Latinos. Conclusions: California Latino men diagnosed with localized high-risk PCa are at increased risk for undertreatment. The observed treatment disparity is largely explained by sociodemographic factors, suggesting it may be ameliorated through targeted outreach, such as that aimed at younger and underinsured Latino men.

A prospective comparison of cancer clinical trial availability and enrollment among adolescents/young adults treated at an adult cancer hospital or affiliated children's hospital

BACKGROUND

Low cancer clinical trial (CCT) enrollment may contribute to survival disparities affecting adolescents and young adults (AYAs) (ages 15-39 years). The objective of this study was to evaluate whether differences in CCT availability related to treatment site could explain the low CCT enrollment.

METHODS

This prospective, observational cohort study was conducted at an academic children's hospital and its affiliated but geographically separated adult cancer hospital within a National Cancer Institute-designated Comprehensive Cancer Center. For consecutive, newly diagnosed AYA patients, it was determined whether an appropriate CCT existed nationally, was available at the treatment site, and was used for enrollment. Proportions of AYAs in these categories were compared between sites using the chi-square test.

RESULTS

One hundred fifty-two consecutive AYA patients were included from the children's hospital (n = 68; ages 15-20 years) and the adult cancer hospital (n = 84; ages 18-39 years). Although there was no difference in CCT existence for individual AYA patients by site (children's hospital [36 of 68 patients; 52.9%] vs adult cancer hospital [45 of 84 patients; 53.6%]; P = .938), CCT availability was significantly lower at the adult cancer hospital (14 of 84 patients [16.7%] vs 30 of 68 [44.1%] at the children's hospital; P < .001). The proportion of AYAs enrolled was low at both sites (8 of 68 patients [11.8%] vs 6 of 84 patients [7.1%], respectively; P = .327). Fewer existing CCTs were available at the adult cancer hospital (4 of 27 patients [14.8%] vs 8 of 14 patients [57.1%], respectively), and those were directed toward solid tumors and new agents.

CONCLUSIONS

Efforts to improve low CCT enrollment among AYAs should be differentiated by treatment site. In the adult setting, these efforts should be aimed at improving CCT availability by overcoming site-level barriers to opening existing CCTs.

The Emerging Potential for Network Analysis to Inform Precision Cancer Medicine

Precision cancer medicine promises to tailor clinical decisions to patients using genomic information. Indeed, successes of drugs targeting genetic alterations in tumors, such as imatinib that targets BCR-ABL in chronic myelogenous leukemia, have demonstrated the power of this approach. However, biological systems are complex, and patients may differ not only by the specific genetic alterations in their tumor, but also by more subtle interactions among such alterations. Systems biology and more specifically, network analysis, provides a framework for advancing precision medicine beyond clinical actionability of individual mutations. Here we discuss applications of network analysis to study tumor biology, early methods for N-of-1 tumor genome analysis, and the path for such tools to the clinic.
