2020 ASCO, 2023 NCCN, 2023 MASCC/ESMO, and 2019 CCO: a comparison of antiemetic guidelines for the treatment of chemotherapy-induced nausea and vomiting in cancer patients

Chemotherapy-induced nausea and vomiting (CINV) is a common toxicity that may impair the quality of life of patients with various malignancies ranging from early to end stages. In light of frequent changes to the guidelines for optimal management of CINV, we undertook this narrative review to compare the most recent guidelines published by ASCO (2020), NCCN (2023), MASCC/ESMO (2023), and CCO (2019). The processes undertaken by each organization to evaluate existing literature were also described. Although ASCO, NCCN, MASCC/ESMO, and CCO guidelines for the treatment and prevention of CINV share many fundamental similarities, the literature surrounding low and minimal emetic risk regimens is lacking. Current data regarding adherence to these guidelines is poor and warrants further investigation to improve care.

An Exploration of the Pillars of Leadership in Cancer Education

Leadership plays a key role in cancer education (CE) and the success of its practices. Leaders in CE must effectively use their leadership skills to be able to communicate, collaborate, and educate their team members. There is a lack of formalized and standardized curriculums for institutions in developing leadership programs, including what themes to focus on in CE. In this article, the authors describe key pillars of leadership in CE that have presented themselves throughout their experience and within the literature. A search was conducted using the Ovid MEDLINE® database and articles were reviewed for eligibility. In this review, thirty articles were selected for their relevance to CE. With this literature search and the authors' reflections, four pillars of leadership in CE were identified: (1) leadership development, (2) collaboration, (3) diversity and equity, and (4) implementation. Within these themes, key areas of importance were discussed further, and barriers to CE leadership were identified. By reflecting upon pillars of leadership in CE, this article may be helpful for developing future leadership programs within CE. It is vital that initiatives continue to be held and barriers are addressed to increase leadership effectiveness within CE.

Patient-reported experience with the use of Mepitel Film for prevention of acute radiation dermatitis in breast cancer

BACKGROUND AND PURPOSE

Mepitel Film (MF) has been demonstrated to reduce the severity of radiation dermatitis (RD) in patients receiving breast cancer radiotherapy (RT). The objective of this study was to characterize patient-reported experience with MF use, including its impact on daily activities and wellbeing.

MATERIALS AND METHODS

This single-institution study analyzed anonymized responses to a questionnaire completed by patients who used MF for the prevention of RD during breast cancer RT.

RESULTS

Of the 254 patients contacted, 192 patients completed the survey. Most patients disagreed or strongly disagreed that MF limited their ability to perform their daily activities, including household chores (88%, n = 169/191), their ability to work (83%, n = 157/189), or their ability to sleep (85%, n = 163/191). Furthermore, patients agreed or strongly agreed MF was comfortable on their skin (67%, n = 126/189) and protected their skin from rubbing against clothing (86%, n = 161/188). Some patients agreed or strongly agreed that MF affected their ability to shower (31%, n = 50/162), wear bras (28%, n = 51/185), and impacted their level of pruritus (35%, n = 67/189). However, most patients agreed or strongly agreed that their overall experience with MF was positive (92%, n = 173/189) and would recommend MF to a friend undergoing breast cancer RT (88%, n = 166/188).

CONCLUSION

MF use is associated with positive patient-reported experience during breast RT with minimal impact on daily activities.

Quality of life issues in patients with bone metastases: A systematic review

INTRODUCTION

Bones are frequent sites of metastatic disease, observed in 30-75% of advanced cancer patients. Quality of life (QoL) is an important endpoint in studies evaluating the treatments of bone metastases (BM), and many patient-reported outcome tools are available. The primary objective of this systematic review was to compile a list of QoL issues relevant to BM and its interventions. The secondary objective was to identify common tools used to assess QoL in patients with BM, and the QoL issues they fail to address.

METHODS

A search was conducted on Ovid MEDLINE, EMBASE, and Cochrane Central Register of Controlled Trials databases between 1946 and 27 January 2023 with the keywords "bone metastases", "quality of life", and "patient reported outcomes". Specific QoL issues in original research studies and the QoL tools used were extracted.

RESULTS

The review identified the QoL issues most prevalent to BM in the literature. Physical and functional issues observed in patients included pain, interference with ambulation and daily activities, and fatigue. Psychological symptoms, such as helplessness, depression, and anxiety were also common. These issues interfered with patients' relationships and social activities. Items not mentioned in existing QoL tools were related to newer treatments of BM, such as pain flare, flu-like symptoms, and jaw pain due to osteonecrosis.

CONCLUSIONS

This systematic review highlights that QoL issues for patients with BM have expanded over time due to advances in BM-directed treatments. If they are relevant, additional treatment-related QoL issues identified need to be validated prospectively by patients and added to current assessment tools.

Quality of life in patients with malignant spinal cord compression: a systematic review

INTRODUCTION

Malignant spinal cord compression (MSCC) is an oncological emergency that may result in a devastating combination of malignancy and disability. Existing quality of life (QoL) questionnaires commonly used in MSCC literature (EORTC QLQ-C30, BM-22, Brief Pain Inventory, and Spine Oncology Study Group Outcomes) may not capture all the commonly reported symptoms and lack specificity to MSCC. The primary objective of this systematic review is to determine unmet patient needs and underreported QoL issues and compile a comprehensive list of QoL issues. The secondary objective of this review is to compile all existing QoL tools and questionnaires and determine whether any QoL issues are not addressed in the existing tools currently used in the literature.

METHODS

A literature search was conducted on Ovid MEDLINE, EMBASE, and Cochrane Central Register of Controlled Trials databases between 1946 and February 6, 2023, to compile all QoL issues and existing questionnaires used to assess QoL in patients with MSCC. All study designs were included given that they discussed QoL issues specific to patients with MSCC.

RESULTS

The results of this systematic review identified the most frequently discussed QoL issues in the literature studying MSCC. This included direct symptoms of MSCC such as back pain, paralysis, limb weakness/numbness, and urinary/bowel incontinence. Indirect symptoms coming from radiotherapy treatment such as dysphagia, painful swallowing, mouth pain, dry mouth, diarrhea, fatigue, and nausea/vomiting were also noted. Other symptoms resulting from corticosteroid treatment included difficulty sleeping, blurring of vision, weight gain, and mood disturbance. Patients also experienced psychosocial issues such as anxiety, depression, emotional distress, low self-esteem, concerns about dependence on others, concerns about getting home, and fear about their prognosis and future.

CONCLUSION

This review highlights the QoL issues specific to patients with MSCC and QoL tools capturing these issues. Relevance of QoL issues identified in this systematic review must be prospectively validated by patients and healthcare professionals with experience in treating MSCC.

Perceptions of healthcare professionals on the use of Mepitel Film for the prevention of acute radiation dermatitis in breast cancer

INTRODUCTION

Randomized clinical trials support Mepitel Film (MF) as a prophylactic treatment for radiation dermatitis (RD) in patients undergoing breast radiotherapy. Although several studies have canvassed the opinion of patients on using MF, no such studies have been done to investigate the perception of healthcare professionals (HCPs). The objective of this study was therefore to investigate the perceptions of HCPs on MF as a treatment option for RD.

METHODS

Anonymized responses to a web-based survey sent to HCPs at a single institution managing patients using MF during breast radiotherapy were analyzed.

RESULTS

Of the 28 HCPs contacted, 22 completed the survey, including 6 radiation oncologists (ROs), 11 radiation therapists (RTTs), and 5 nurses. Most HCPs reported MF was better at preventing severe RD than the standard of care and improved radiation-induced skin reactions (n = 20/22, 91%, and n = 19/22, 86%, respectively). MF was recommended for mastectomy patients without reconstruction (n = 15/21, 71%). The majority of HCPs believed that patients' families could be trained to apply and remove MF (n = 19/22, 86%). Many HCPs perceived that implementation of MF would be difficult in terms of maintaining patient flow and wide-scale implementation within their institution (n = 11/22, 50%, and n = 10/22, 46%, respectively). Most HCPs perceived that fewer than 50% of their patients could afford MF if priced at $100 CAD (n = 15/20, 75%).

CONCLUSION

These findings provide insights into the possibility of MF to be incorporated into standard practice of care for RD. Although most HCPs were satisfied with MF as a prophylactic treatment for RD, there are concerns about its resource-intensive operationalization and financial accessibility to patients. Future research should focus on ways to improve HCP experience with MF and to improve its implementation into clinical settings as standard of care.

StrataXRT for the prevention and treatment of radiation dermatitis: a critical review

PURPOSE

The primary objective is to systematically review primary studies, such as randomized control trials (RCTs), feasibility, exploratory, and case studies; and the secondary objective is to evaluate all secondary articles, such as reviews, guidelines, and editorials, relevant to the use of StrataXRT for the prevention and/or management of radiation dermatitis (RD) in cancer patients.

METHODS

A literature search was conducted up to February 26, 2023, for articles investigating the use of StrataXRT for the prevention and treatment of RD, in the following databases: Ovid MEDLINE, Embase, Cochrane Central Register of Controlled Trials (CENTRAL), and Google Scholar. The keywords "StrataXRT", "dermatitis", "radiotherapy", and "radiation" were used to identify relevant articles.

RESULTS

Twenty-seven articles from 2018 to 2022 were identified to fulfill the inclusion criteria of this review, of which nine are primary studies and 18 are secondary papers. Significant heterogeneity was observed in the current literature studying the effects of StrataXRT, making it difficult to make cross-trial comparisons. There is a suggestion of the efficacy of StrataXRT in the prevention and treatment of RD.

CONCLUSION

The findings of this review recommend further adequately powered RCTs with robust methodology including patient and clinician assessments to determine the efficacy of StrataXRT in preventing and treating RD. This is essential to improve the quality of life of patients and identify which groups of patients would benefit most from StrataXRT.

Mepitel film for the prevention and treatment of acute radiation dermatitis in breast cancer: a systematic review and meta-analysis of randomized controlled trials

PURPOSE

This systematic review and meta-analysis aimed to evaluate the efficacy of Mepitel film in preventing or treating acute radiation dermatitis (RD) in patients with breast cancer in randomized controlled trials (RCTs).

METHODS

Embase, APA PsychInfo, Journals@Ovid Full Text, Ovid MEDLINE, PubMed, and Cochrane Trials were searched until December 12, 2022, to identify RCTs on the use of Mepitel film for preventing or treating acute RD from breast cancer radiotherapy. Per-protocol analysis was used to compare outcomes, calculate pooled effect sizes, odds ratio (OR), and 95% confidence intervals (CI), and to create forest plots using random effects analysis in RevMan 5.4.

RESULTS

Three RCTs were included in this review. Mepitel film significantly reduced the incidence of grade 3 RD (OR 0.15 95% CI 0.06, 0.37, p<0.0001) and grade 2 or 3 RD (OR 0.16 95% CI 0.04, 0.65, p=0.01) as scored on either the CTCAE or the RTOG scale. Additionally, Mepitel film significantly reduced RISRAS mean scores assessed by patients and combined researcher and patient (standardized mean difference (SMD) -7.59, 95% CI -14.42, -0.76, p=0.03; SMD -15.36, 95% CI -30.01, -0.71 p=0.04) but not the researcher component of the assessment tool (SMD -17.55, 95% CI -36.94, 1.84, p=0.08).

CONCLUSION

Mepitel film reduced the incidence of acute RD and improved patient-reported outcomes with minimal side effects, the main one being itchiness. Future research should assess the feasibility of Mepitel film with respect to specific patient-reported outcomes such as health-related quality of life issues associated with its use.

StrataXRT for the prevention of acute radiation dermatitis in breast cancer: a systematic review and meta-analysis of randomized controlled trials

PURPOSE

To evaluate the overall efficacy of StrataXRT, a topical gel dressing, in preventing acute radiation dermatitis (RD) in breast cancer patients undergoing radiotherapy (RT).

METHODS

A systematic search was conducted on April 25, 2023 in Ovid MEDLINE, Embase, and Cochrane Central Register of Controlled Trials. Randomized controlled trials (RCTs) assessing the effectiveness of StrataXRT in preventing acute RD in breast cancer patients undergoing adjuvant RT to the breast or chest wall with or without regional nodes were included. Pooled incidence odds ratio (OR) and 95% confidence interval (CI) were calculated using a random-effects model, with analysis and forest plots generated in RevMan v5.4.

RESULTS

The analysis included three RCTs with a total of 189 patients assessed using per-protocol analysis. Two RCTs compared StrataXRT to standard of care, while the third compared it with Mepitel film and was reported separately. In the former RCTs, the odds ratio (OR) for developing acute grade 3 RD favored StrataXRT at 0.05 (95% CI, 0.01-0.22; P < 0.0001). The OR for developing acute grades 2-3 RD was 0.32 (95% CI, 0.03-3.18; P = 0.33). The RCT comparing StrataXRT with Mepitel film showed insignificant ORs for grade 3 and grades 2-3 RD. One RCT reported significantly lower erythema index (P = 0.008) and melanin index (P = 0.015) in StrataXRT patients. The use of StrataXRT did not raise additional safety concerns.

CONCLUSION

StrataXRT may help prevent severe acute RD in breast cancer RT patients. Further high quality, large-scale studies are needed to confirm these findings.

Investigation of the composition of arterial plaques based on arterial waveforms and material properties

Stroke is mainly caused by a narrowing of the carotid artery from a build-up of plaque. The risk of plaque rupture and subsequent stroke is dependent on plaque composition. Advances in imaging modalities offer a non-invasive means to assess the health of blood vessels and detect damage. However, the current diagnosis fails to identify patients with soft lipid plaque that are more susceptible to fissure, resulting in stroke. The aim of this study was to use waveform analysis to identify plaque composition and the risk of rupture. We have investigated pressure and flow by combining an artificial blood flow circuit with tubing containing different materials, to simulate plaques in a blood vessel. We used fat and bone to model lipid and calcification respectively to determine if the composition of plaques can be identified by arterial waveforms. We demonstrate that the arterial plaque models with different percentages of calcification and fat, results in significantly different arterial waveforms. These findings imply that arterial waveform analysis has the potential for further development to identify the vulnerable plaques prone to rupture. These findings could have implications for improved patient prognosis by speed of detection and a more appropriate treatment strategy.
