Healthcare providers have reported challenges with coordinating care for patients with cancer. Digital technology tools have brought new possibilities for improving care coordination. A web- and text-based asynchronous system (eOncoNote) was implemented in Ottawa, Canada for cancer specialists and primary care providers (PCPs). This study aimed to examine PCPs' experiences of implementing eOncoNote and how access to the system influenced communication between PCPs and cancer specialists. As part of a larger study, we collected and analyzed system usage data and administered an end-of-discussion survey to understand the perceived value of using eOncoNote. eOncoNote data were analyzed for 76 shared patients (33 patients receiving treatment and 43 patients in the survivorship phase). Thirty-nine percent of the PCPs responded to the cancer specialist's initial eOncoNote message and nearly all of those sent only one message. Forty-five percent of the PCPs completed the survey. Most PCPs reported no additional benefits of using eOncoNote and emphasized the need for electronic medical record (EMR) integration. Over half of the PCPs indicated that eOncoNote could be a helpful service if they had questions about a patient. Future research should examine opportunities for EMR integration and whether additional interventions could support communication between PCPs and cancer specialists.

Dermatofibrosarcoma protuberans (DFSP) is a cutaneous sarcoma that has remained a challenge for oncologic and reconstructive surgeons due to a high rate of local recurrence. The objective of this study is to investigate the oncologic and reconstructive benefits of employing a multidisciplinary two-step approach to the treatment of DFSP. A retrospective review was conducted using a prospectively collected database of all patients who underwent resection and reconstruction of large DFSPs by a multidisciplinary team, including a Mohs micrographic surgeon, surgical oncologist, dermatopathologist, and plastic and reconstructive surgeon, at one academic institution from 1998-2018. Each patient underwent Mohs micrographic surgery for peripheral margin clearance (Step 1) followed by wide local excision (WLE) of the deep margin by surgical oncology and immediate reconstruction by plastic surgery (Step 2). 57 patients met inclusion criteria. Average defect size after WLE (Step 2): 87.3 cm2 (range 8.5-1073.5 cm2). Mean follow-up time was 37 months (range 0-138 months). There were no cases of recurrence. A two-step multidisciplinary surgical treatment approach for DFSP minimizes risk of recurrence, decreases patient discomfort, and allows immediate reconstruction after deep margin clearance.

BACKGROUND: In India, caregivers are an integral part of the illness experience, especially in cancer, to the extent that they can become proxy decision-makers for the patient. Further, owing to acute resource constraints in the Indian healthcare system, it may be difficult for oncologists to assess and elicit questions from each patient/caregiver. Consequently, there is a need to address these unique aspects of oncology care in India to improve patient outcomes and understanding of their illness and treatment. This can be achieved through a Question Prompt List (QPL), a checklist used by care recipients during medical consultations. RECENT FINDINGS: This narrative review will first introduce research on the development and effectiveness of the QPL, and then it will highlight current gaps in oncology care in India and explore how the QPL may aid in closing these gaps. A literature search of the empirical research focused on the development, feasibility and acceptability of the QPL in oncology settings was conducted. The final review included 40 articles pertaining to QPL research. Additionally, psycho-oncology research in India centered on information needs and experiences was reviewed. Current Indian psycho-oncology research reports patients' want to be actively involved in their cancer care and a need for more illness information. However, a high demand on physicians' resources and the family caregivers' interference can be barriers to meeting patients' information/communication needs. International research demonstrates that a QPL helps structure and decrease consultation time, improves patient satisfaction with care, and improves the quality of communication during medical encounters. CONCLUSION: QPLs for Indian patients and caregivers may focus on the scope of medical consultations to address patient needs while influencing the course and content of the patient-caregiver-physician interactions. Further, it can address the resource constraints in Indian oncology care settings, thus reducing the physician's burden.

The emergency caused by COVID-19 pandemic has imposed a sudden reorganization of the healthcare structures and has created consequences in cancer patients management. General clinical recommendations for cancer patients were released, even if limited clinical cancer-specific data were available. A number of critical issues have come out during COVID-19 pandemic in the management of patients with metastatic breast cancer (MBC). To explore the changes in the treatment of patients with MBC during COVID-19 pandemic, we promoted a survey to the oncologists operating in the Italian breast units. The results of this survey show that Italian oncologists have tried to ensure continuity of care for patients with MBC. De-escalation of cancer treatments, especially monotherapy administration, and greater use of oral anticancer drugs are the main changes that emerge from this survey. Some subgroups of patients, especially the elderly and endocrine-responsive patients, have been undertreated during the COVID-19 pandemic.

Gender parity within academic oncology is important. We hypothesized that gender differences exist in subspecialty choice and academic rank among medical oncologists. We performed a cross-sectional study of adult medical oncologists at the top 15 cancer centers. Gender, rank, subspecialty (breast, thoracic, gastrointestinal, and genitourinary) and board certification year were recorded. 570 medical oncologists were identified (60% men; 40% women). More women practice breast oncology (OR 3.1, p < 0.001), but less practice genitourinary oncology (OR 0.37, p < 0.001). 22% of women were full professors vs 34% of men (OR 0.55, p = 0.001). Gender differences persist in academic adult medical oncology.

PURPOSE: In response to the COVID-19 pandemic, the ASCO launched a Global Webinar Series to address various aspects of cancer care during the pandemic. Here we present the lessons learned and recommendations that have emerged from these webinars. METHODS: Fifteen international health care experts from different global regions and oncology disciplines participated in one of the six 1-hour webinars to discuss the latest data, share their experiences, and provide recommendations to manage cancer care during the COVID-19 pandemic. These sessions include didactic presentations followed by a moderated discussion and questions from the audience. All recommendations have been transcribed, categorized, and reviewed by the experts, who have also approved the consensus recommendations. RESULTS: The summary recommendations are divided into different categories, including risk minimization; care prioritization of patients; health care team management; virtual care; management of patients with cancer undergoing surgical, radiation, and systemic therapy; clinical research; and recovery plans. The recommendations emphasize the protection of patients and health care teams from infections, delivery of timely and appropriate care, reduction of harm from the interruption of care, and preparation to handle a surge of new COVID-19 cases, complications, or comorbidities thereof. CONCLUSION: The recommendations from the ASCO Global Webinar Series may guide practicing oncologists to manage their patients during the ongoing pandemic and help organizations recover from the crisis. Implementation of these recommendations may improve understanding of how COVID-19 has affected cancer care and increase readiness to manage the current and any future outbreaks effectively.

BACKGROUND: Patients suffering from cancers are increasingly numerous in general practice consultations. The General Practitioner (GP) should be at the heart of the management of patients. Several studies have examined the perceptions of GPs confronted with the patient suffering from cancer and the relationships of GPs with oncologists, but few studies have focused on the patients' perspective. We studied the three-way relationship between the oncologist, the GP, and the patient, from the patient's point of view. METHODS: A questionnaire validated by a group consisting of GPs, oncologists, nurses, an epidemiologist and quality analyst, was administered over a three-week period to patients suffering from cancer receiving chemotherapy in a day hospital. RESULTS: The analysis was based on 403 questionnaires. Patients had confidence in the GP's knowledge of oncology in 88% of cases; 49% consulted their GP for pain, 15% for cancer-related advice, and 44% in emergencies. Perceived good GP/oncologist communication led patients to turn increasingly to their GP for cancer-related consultations (RR = 1.14; p = 0.01) and gave patients confidence in the GP's ability to manage cancer-related problems (RR = 1.30; p < 0.01). Mention by the oncologist of the GP's role increased the consultations for complications (RR = 1.82; p < 0.01) as well as recourse to the GP in an emergency (RR = 1.35; p < 0.01). CONCLUSION: Patients suffering from cancer considered that the GP was competent, but did not often consult their GP for cancer-related problems. There is a discrepancy between patients' beliefs and their behaviour. When the oncologist spoke to patients of the GP's role, patients had recourse to their GP more often. Systematically integrating a GP consultation to conclude cancer diagnosis disclosure, could improve management and care coordination.

INTRODUCTION: Narrative medicine makes explicit the experience of disease and enhances the subjective view in the cure. In addition, the narrative approach involves personal experience and emotional resonances of the health care professional leading him to redefine the values in terms of health and disease. The IMPERO study aims to explore the personal "life experience" of health care professionals involved in studies exploring a new methodological clinical approach: the use of a digital narrative diary in collecting and integrating theme-oriented narration in clinical practice. METHODS: Qualitative study based on the interviews of three health care professionals (two oncologists and one nurse) involved in the AMENO study. The main topic of the interviews was the "perceived" and the intimate experience of each health care professional, particularly on the meaning and the role regarding their personal and professional experience while coping with patients narration. The analysis of data focuses on three aspects: a) the health care professionals' point of view using the diary as a tool for narrative-based medicine; b) the work environment as a framework for the use of the digital diary; c) the mental construction concerning the meaning of the tool and its preliminary use in clinical practice. RESULTS: The diary is appreciate as a tool for the application of narrative-based medicine; the reading/writing format is considered of high quality and suitable for clinical practice processes. The narration drives a change in the patient-health care professional relationship: the patient is valued as an "individual". An atmosphere of empathy and greater intimacy is created. The perceptions developed over the years of clinical practice, which reflect personal and professional concepts (knowledge and individual believes in illness, health, healing, etc.), influence the perception of the narrative instrument and its clinical use. The work context influences the use of the diary, limiting its potential. Narrative medicine is a way of reorganizing the criteria that contribute in defining the quality of patient care by focusing on the patient-health care professional relationship. DISCUSSION: The approach of narrative medicine must be reviewed in the light of the relational systemic theory which allows us to understand several aspects: the training in narrative medicine itself, the acquisition of professional skills by practitioners, and the organizational development of the institutions (the organizational structures but also the values and professional culture of work).

PURPOSE: To study factors that have an impact on the conduct of high-quality goals of care (GoC) discussions and productivity of oncologists among four different practice settings in patients with advanced cancer. METHODS: Solid-tumor oncologists from community, academic, municipal, and rural hospitals were randomly assigned to receive a coaching model of communication skills to help them facilitate a GoC discussion with newly diagnosed patients with advanced cancer who had a less-than-2-year prognosis. Patients were surveyed after the first restaging visit regarding the quality of the GoC discussion on a scale of 0 to 10 (0, worst; 10, best) with a score of 8 or better indicating a high-quality GoC discussion. Productivity was measured by work revenue value units (wRVUs) per hour for the day each oncologist saw the study patient after imaging. RESULTS: The four sites differed significantly in the socioeconomic patient populations they served and in the characteristics of the oncologists who cared for the patients. Overall median productivity across the four sites was 3.6 wRVU/hour, with the highest observed in the community hospital (4.3 wRVU/hour) and the lowest in the rural setting (2.9 wRVU/hour; P < .001). There was no significant difference in productivity observed when high-quality GOC discussion occurred versus when it did not (3.6 v 3.7 wRVU/hour; P = .86). CONCLUSION: Despite differences in patient populations and oncologists' characteristics between the four practice settings, the conduct of high-quality GoC discussions did not affect productivity.

Imaging has a key role in the assessment of paediatric renal tumours, especially when the initial treatment approach is to proceed to standard chemotherapy without histological confirmation. In Europe, according to the International Society of Paediatric Oncology guidelines, core needle biopsy is not routinely done unless the child is older than 10 years. Between age 6 months and 9 years, the child is treated with a standard regimen of preoperative chemotherapy unless there are concerns about non-Wilms' tumour pathology. Atypical imaging findings could therefore stratify a child into a different treatment protocol, and can prompt the need for pretreatment histology. This review details the latest protocols and techniques used in the assessment of paediatric renal tumours. Important imaging findings are discussed, especially the features that might prompt the need for a pretreatment biopsy. Local radiology practices vary, but both MRI and CT are widely used as routine imaging tests for the assessment of paediatric renal tumours in Europe. Advances in imaging technology and MRI sequences are facilitating the development of new techniques, which might increase the utility of imaging in terms of predicting tumour histology and clinical behaviour. Several of these new imaging techniques are outlined here.

BACKGROUND: Patients receiving radiotherapy for the treatment of cancer can have complex medication requirements related to the management of side-effects and impaired swallowing ability. This study surveyed patients and clinicians to identify service gaps and unmet medication management needs. METHODS: Patient and clinician surveys were developed by a multidisciplinary team based on previously validated questionnaires. The patient survey focused on medication use and adherence. The clinician survey was based around a clinical case study and focused on identifying service gaps and practice variations. This survey was disseminated to radiation oncologists, pharmacists and nurses involved with the care of head and neck or lung cancer patients in Victoria. RESULTS: A total of 93 surveys were completed including 53 patient surveys and 40 clinician surveys. Radiotherapy patients reported high medication usage with up to 53% taking five or more medications daily. When asked the same set of questions relating to medication education requirements, patients receiving polypharmacy reported greater needs (72%) than recognised by the surveyed multidisciplinary clinician group (58%). They also reported a non-adherence rate of 46%. In addition, further disparities were identified in clinician practices and their approach to clinical situations which may result in conflicting advice and confusion for patients. CONCLUSION: While recognising deficiencies relating to the provision of medication information, oncologists, nurses and pharmacists underestimated patient needs for medication information, education and follow-up. Findings support the rationale for integration of pharmacy services within the radiotherapy clinics to support patient care and bridge service gaps relating to medication management.

BACKGROUND: Overwhelming randomized controlled trial evidence demonstrates that exercise has positive health impacts during and after treatment for breast cancer. Yet, evidence generated by studies in which exercise programs are delivered outside a tightly controlled randomized trial setting is limited. The purpose of this study was to assess the effectiveness of an evidence-based exercise program with real-world implementation on physical fitness and quality of life (QoL). PATIENTS AND METHODS: Oncologists referred women with early-stage breast cancer who were scheduled to receive adjuvant chemotherapy. The program consisted of supervised aerobic and resistance exercise of moderate to vigorous intensity 3 times per week until the end of treatment (chemotherapy ± radiotherapy), then twice per week for 10 weeks, followed by once per week for 10 weeks. Health-related physical fitness and QoL were assessed at baseline, end of treatment, end of program, and 1-year follow-up. RESULTS: A total of 73 women were enrolled. Estimated peak VO2 (VO2peak), QoL, and body weight were maintained between baseline and end of treatment, whereas muscular strength improved (P<.01). By the end of the program, VO2peak, heart rate recovery, waist circumference, and some aspects of QoL were improved (all P<.01) relative to baseline. One year later, VO2peak, QoL, and waist circumference were maintained relative to end of program, whereas the improvements in strength and heart rate recovery had dissipated (all P<.01). CONCLUSIONS: Evidence-based exercise programming delivered with real-world implementation maintained VO2peak, strength, and QoL during adjuvant treatment and improved these measures after treatment completion among women with breast cancer. Continued guidance and support may be required for long-term maintenance of strength improvements in this population.

Background: In Canada, requests for public reimbursement of cancer drugs are predominately initiated by pharmaceutical manufacturers. Clinician-led submissions provide a mechanism to initiate the drug funding process when industry does not submit a request for funding consideration. Although such requests are resource-intensive to produce, Cancer Care Ontario (cco) has the capacity to facilitate clinician-led submissions. In 2014, cco began developing a cancer drug prioritization framework that allocates resources to systematically address a growing number of clinician-identified funding gaps with clinician-led submissions. Methods: Cancer site-specific drug advisory committees established by cco consist of health care practitioners whose roles include identifying and prioritizing funding gaps. The committees submit their identified gaps to a cross-cancer-site prioritization exercise in which the requests are ranked based on a set of guiding principles derived from health technology assessment. The requests are then sequentially allocated the resources needed to meet submission requirements. Whether the funding gap is of provincial or pan-Canadian relevance determines where the submission is filed for assessment. Results: Since its inception, the cco framework has identified 17 funding gaps in 9 cancer sites. In 4 prioritizations, the framework supported 6 submissions. As of June 2018, the framework had contributed to the eventual funding of more than 9 new drug-indication pairs, with more awaiting funding consideration. Conclusions: The cco prioritization framework has enabled clinicians to effectively and systematically identify, prioritize, and fill funding gaps not addressed by industry. Ultimately, the framework helps to ensure that patients can access evidence-informed and cost-effective therapies. The framework will continue to evolve as it encounters new challenges, including funding requests for rare indications.

Hospital-physician integration has substantially grown in the United States for the past decade, particularly in certain medical specialties, such as oncology. Yet evidence is scarce on the relation between integration and outpatient specialty care use and spending. We analyzed the impact of oncologist integration on outpatient provider-administered chemotherapy use and spending in Medicare, where prices do not depend on providers' integration status or negotiating power. We addressed oncologists' selective integration and patients' nonrandom choice of oncologists using an instrumental variables method. We found that integrated oncologists reduced the quantity of outpatient chemotherapy drugs but used more expensive treatments. This led to an increase in chemotherapy-drug spending after integration. These findings suggest that changes in treatment patterns-treatment mix and quantity-may be an important mechanism by which integration increases spending. We also found that integration increased spending on chemotherapy administration (the act of injection). This is because integration shifted billing of chemotherapy to hospital outpatient departments, where Medicare payments for chemotherapy administration are higher than those in physician offices. As integration increases, efforts should continue to assess how integration influences patient care and explore policy options to ensure desirable outcomes from integration.

CONTEXT: To date, established risk factors for prostate cancer (PCa) are limited to age, race, family history, and certain genetic polymorphisms. Despite great research efforts, available evidence on potentially modifiable risk factors is conflicting. Moreover, most studies on PCa risk factors did not consider the impact of prostate-specific antigen (PSA) testing on PCa diagnosis. OBJECTIVE: To provide a detailed overview of the latest evidence on the role of metabolic diseases, drugs, and dietary factors for risk of PCa incidence, recurrence, and survival in men exposed to PSA testing. EVIDENCE ACQUISITION: A systematic review of the English-language literature was performed using the MEDLINE, Cochrane Central Register of Controlled Trials, and Web of Science databases according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses recommendations. Randomized, case-control, or cohort studies published during the periods 2008-2017 (on drugs and metabolic diseases) and 2003-2017 (on dietary factors), with extensive follow-up (≥8-10yr for studies on PCa risk; ≥2-5yr for studies on PCa recurrence, progression, and survival, depending on the review subtopic) and adjusting of the analyses, beyond established risk factors, for either rate of PSA testing (for risk analyses) or PCa stage and primary treatment (for survival analyses), were eligible for inclusion. EVIDENCE SYNTHESIS: Overall, 39 reports from 22 observational studies were included. Studies were heterogeneous regarding definitions of exposure or outcomes, length of follow-up, risk of bias, and confounding. For some risk factors, evidence was insufficient to assess potential effects, while for others there was no evidence of an effect. For selected risk factors, namely metformin, aspirin and statin use, diabetes, obesity, and specific dietary intakes, there was low-quality evidence of modest effects on PCa risk. CONCLUSIONS: Current evidence from long-term observational studies evaluating the effect of drugs, metabolic diseases, and dietary factors for PCa risk considering the impact of PSA testing is still not conclusive. Future research is needed to confirm the associations suggested by our review, exploring their potential biological explanations and selecting those risk factors most likely to trigger effective public health interventions. PATIENT SUMMARY: We reviewed the available studies published in the recent literature on the potential role of drugs, metabolic diseases, and food and dietary factors for the risk of prostate cancer, considering the impact of prostate-specific antigen testing on prostate cancer diagnosis. We found that for some factors data are currently insufficient to make definitive conclusions, while for others available studies seem to indicate an effect on the risk of prostate cancer.
