Meta-Analysis Review
BACKGROUND
This is the third update of a review that was originally published in the Cochrane Library in 2002, Issue 2. People with cancer, their families and carers have a high prevalence of psychological stress, which may be minimised by effective communication and support from their attending healthcare professionals (HCPs). Research suggests communication skills do not reliably improve with experience, therefore, considerable effort is dedicated to courses that may improve communication skills for HCPs involved in cancer care. A variety of communication skills training (CST) courses are in practice. We conducted this review to determine whether CST works and which types of CST, if any, are the most effective.
OBJECTIVES
To assess whether communication skills training is effective in changing behaviour of HCPs working in cancer care and in improving HCP well-being, patient health status and satisfaction.
SEARCH METHODS
For this update, we searched the following electronic databases: Cochrane Central Register of Controlled Trials (CENTRAL; 2018, Issue 4), MEDLINE via Ovid, Embase via Ovid, PsycInfo and CINAHL up to May 2018. In addition, we searched the US National Library of Medicine Clinical Trial Registry and handsearched the reference lists of relevant articles and conference proceedings for additional studies.
SELECTION CRITERIA
The original review was a narrative review that included randomised controlled trials (RCTs) and controlled before-and-after studies. In updated versions, we limited our criteria to RCTs evaluating CST compared with no CST or other CST in HCPs working in cancer care. Primary outcomes were changes in HCP communication skills measured in interactions with real or simulated people with cancer or both, using objective scales. We excluded studies whose focus was communication skills in encounters related to informed consent for research.
DATA COLLECTION AND ANALYSIS
Two review authors independently assessed trials and extracted data to a pre-designed data collection form. We pooled data using the random-effects method. For continuous data, we used standardised mean differences (SMDs).
MAIN RESULTS
We included 17 RCTs conducted mainly in outpatient settings. Eleven trials compared CST with no CST intervention; three trials compared the effect of a follow-up CST intervention after initial CST training; two trials compared the effect of CST and patient coaching; and one trial compared two types of CST. The types of CST courses evaluated in these trials were diverse. Study participants included oncologists, residents, other doctors, nurses and a mixed team of HCPs. Overall, 1240 HCPs participated (612 doctors including 151 residents, 532 nurses, and 96 mixed HCPs).Ten trials contributed data to the meta-analyses. HCPs in the intervention groups were more likely to use open questions in the post-intervention interviews than the control group (SMD 0.25, 95% CI 0.02 to 0.48; P = 0.03, I² = 62%; 5 studies, 796 participant interviews; very low-certainty evidence); more likely to show empathy towards their patients (SMD 0.18, 95% CI 0.05 to 0.32; P = 0.008, I² = 0%; 6 studies, 844 participant interviews; moderate-certainty evidence), and less likely to give facts only (SMD -0.26, 95% CI -0.51 to -0.01; P = 0.05, I² = 68%; 5 studies, 780 participant interviews; low-certainty evidence). Evidence suggesting no difference between CST and no CST on eliciting patient concerns and providing appropriate information was of a moderate-certainty. There was no evidence of differences in the other HCP communication skills, including clarifying and/or summarising information, and negotiation. Doctors and nurses did not perform differently for any HCP outcomes.There were no differences between the groups with regard to HCP 'burnout' (low-certainty evidence) nor with regard to patient satisfaction or patient perception of the HCPs communication skills (very low-certainty evidence). Out of the 17 included RCTs 15 were considered to be at a low risk of overall bias.
AUTHORS' CONCLUSIONS
Various CST courses appear to be effective in improving HCP communication skills related to supportive skills and to help HCPs to be less likely to give facts only without individualising their responses to the patient's emotions or offering support. We were unable to determine whether the effects of CST are sustained over time, whether consolidation sessions are necessary, and which types of CST programs are most likely to work. We found no evidence to support a beneficial effect of CST on HCP 'burnout', the mental or physical health and satisfaction of people with cancer.

Review
BACKGROUND
The loss of muscle mass, known as sarcopenia, is a natural process of aging that is associated with adverse health outcomes regardless of age. Because cancer is a disease of aging, interest in sarcopenia and its potential impact in multiple cancer populations has increased significantly. Bioelectrical impedance analysis (BIA) is a guideline-accepted method for sarcopenia detection. This systematic review assesses the literature pertaining to BIA use in the detection of sarcopenia in adults with cancer.
MATERIALS AND METHODS
In this systematic review, a search of the literature for randomized controlled trials and observational studies was conducted using MEDLINE, Cochrane CENTRAL, and EMBASE, through July 15, 2019. The study is registered at Prospero (CRD 42019130707). For study inclusion, patients had to be aged 18 years or older and diagnosed with solid or hematological neoplasia, and BIA had to be used to detect sarcopenia.
RESULTS
Through our search strategy, 5,045 articles were identified, of which 24 studies were selected for inclusion in the review (total number of 3,607 patients). In five studies, BIA was rated comparable to axial computed tomography (CT) scan, calf circumference, or grip strength for sarcopenia screening. In 14 studies, BIA-identified sarcopenia was associated with adverse clinical outcomes.
CONCLUSION
BIA is an accurate method for detecting sarcopenia in adults with cancer prior to treatment and is a viable alternative to CT, dual-energy x-ray absorptiometry, and magnetic resonance imaging in oncology clinical practice.
IMPLICATIONS FOR PRACTICE
Bioelectrical impedance analysis (BIA) is an attractive method for identifying sarcopenic patients in clinical practice because it provides an affordable, noninvasive test that can be completed within a few minutes during a clinic visit. BIA does not require highly skilled personnel, and results are immediately available. This systematic review summarizes the literature pertaining to BIA assessment of sarcopenia in adults with cancer, with a focus on its use in diverse cancer populations.

Neurology Apr 2021To define the clinical characteristics, management, and outcome of neurologic immune-related adverse events (n-irAEs) of immune checkpoint inhibitors (ICIs).
OBJECTIVE
To define the clinical characteristics, management, and outcome of neurologic immune-related adverse events (n-irAEs) of immune checkpoint inhibitors (ICIs).
METHODS
Systematic review of the literature following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines.
RESULTS
A total of 694 articles were identified. Two hundred fifty-six articles, with 428 individual patients, met the inclusion criteria. Reports regarding neuromuscular disorders (319/428, 75%) were more frequent than those on CNS disorders (109/428, 25%). The most common n-irAEs reports were myositis (136/428, 32%), Guillain-Barré syndrome and other peripheral neuropathies (94/428, 22%), myasthenic syndromes (58/428, 14%), encephalitis (56/428, 13%), cranial neuropathies (31/428, 7%), meningitis (13/428, 3%), CNS demyelinating diseases (8/428, 2%), and myelitis (7/428, 2%). Other CNS disorders were detected in 25/428 (6%) patients. Compared with the whole sample, myasthenic syndromes were significantly more Ab positive (33/56, 59%; < 0.001). Anti-programmed cell death protein 1/programmed cell death ligand 1 was more frequent in myasthenic syndromes (50/58, 86%; = 0.005) and less common in meningitis (2/13, 15%; < 0.001) and cranial neuropathies (13/31, 42%; = 0.005). Anti-cytotoxic T-lymphocyte antigen-4 ICIs were more frequent in meningitis (8/13, 62%; < 0.001) and less common in encephalitis (2/56, 4%; = 0.009) and myositis (12/136, 9%; = 0.01). Combination of different ICIs was more frequent in cranial neuropathies (12/31, 39%; = 0.005). Melanoma was more frequent in patients with peripheral neuropathies (64/94, 68%; = 0.003) and less common in encephalitis (19/56, 34%; = 0.001). The highest mortality rate was reached in myasthenic syndromes (28%).
CONCLUSION
Considering the increasing use of ICI therapy in the forthcoming future, this information can be valuable in assisting neurologists and oncologists in early n-irAEs diagnosis and treatment.

Review
The use of tyrosine kinase inhibitors (TKI) has gained significant importance in veterinary cancer patients over the last decade. Toceranib phosphate has been licensed for the treatment of dogs with mast cell tumours. Its molecular similarity to sunitinib, a TKI used in human medicine, has led many veterinary oncologists to use this agent for multiple neoplastic diseases. The aim of the current study was to perform a systematic review of the evidence for the use of toceranib in dogs with non-mast cell neoplasia. Two electronic databases were searched. Publications were included if toceranib was used as a treatment option in canine patients. Studies and case reports were excluded if toceranib was used as part of a multi-modal treatment plan and response or outcome data related to toceranib therapy were not described. A total of 28 studies were included from 122 references. The most common types of neoplasias identified were neuroendocrine tumours, anal gland sac adenocarcinoma, and osteosarcoma. Multiple other neoplasias had one or two studies identified to describe the use of toceranib. Results of the study support that toceranib phosphate may have efficacy against certain types of neoplasia under certain conditions, such as neuroendocrine tumours, gastrointestinal stromal tumours and anal sac adenocarcinomas, while it is probably not effective for the management of metastatic osteosarcoma based on the findings of the review.

PURPOSE
To update evidence-based guideline recommendations to practicing oncologists and others on systemic therapy for patients with human epidermal growth factor receptor 2 (HER2)-positive advanced breast cancer.
METHODS
An Expert Panel conducted a targeted systematic literature review (for both systemic treatment and CNS metastases) and identified 545 articles. Outcomes of interest included efficacy and safety.
RESULTS
Of the 545 publications identified and reviewed, 14 were identified to form the evidentiary basis for the guideline recommendations.
RECOMMENDATIONS
HER2-targeted therapy is recommended for patients with HER2-positive advanced breast cancer, except for those with clinical congestive heart failure or significantly compromised left ventricular ejection fraction, who should be evaluated on a case-by-case basis. Trastuzumab, pertuzumab, and taxane for first-line treatment and trastuzumab deruxtecan for second-line treatment are recommended. In the third-line setting, clinicians should offer other HER2-targeted therapy combinations. There is a lack of head-to-head trials; therefore, there is insufficient evidence to recommend one regimen over another. The patient and the clinician should discuss differences in treatment schedule, route, toxicities, etc during the decision-making process. Options include regimens with tucatinib, trastuzumab emtansine, trastuzumab deruxtecan (if either not previously administered), neratinib, lapatinib, chemotherapy, margetuximab, hormonal therapy, and abemaciclib plus trastuzumab plus fulvestrant, and may offer pertuzumab if the patient has not previously received it. Optimal duration of chemotherapy is at least 4-6 months or until maximum response, depending on toxicity and in the absence of progression. HER2-targeted therapy can continue until time of progression or unacceptable toxicities. For patients with HER2-positive and estrogen receptor-positive or progesterone receptor-positive breast cancer, clinicians may recommend either standard first-line therapy or, for selected patients, endocrine therapy plus HER2-targeted therapy or endocrine therapy alone.Additional information is available at www.asco.org/breast-cancer-guidelines.

BACKGROUND
The development of immune checkpoint inhibitors (ICIs) represents a paradigm shift in the treatment of cancers. Despite showing remarkable efficacy, these agents can be associated with life-threatening immune-related adverse events. In recent years, several cases of myocarditis with myositis and/or myasthenia gravis overlap syndrome (IM3OS) have been reported. However, given the rarity, the clinical features and outcomes of these cases remain poorly understood. We, therefore, attempted to systematically review and summarize all cases of IM3OS reported in the literature.
MATERIALS AND METHODS
Studies reporting IM3OS were identified in Embase and MEDLINE. Only case reports and case series published in journals or presented at conferences were included. We conducted a systematic review according to the PRISMA Harms guidelines.
RESULTS
A total of 60 cases were eligible. The patients' median age was 71 years, and the majority (67%) were males; melanoma was the most common indication for ICIs (38%). The most-reported symptoms were fatigue (80%) and muscle weakness (78%). The median number of doses to the development of IM3OS was one. The average creatine kinase level was 9,645 IU/L. Cardiac arrhythmias occurred in 67% of patients, and 18% had depressed ejection fraction. Initial treatment consisted of immunosuppression with high-dose steroids and supportive therapies. Sixty percent of the patients died in hospital because of acute complications.
CONCLUSION
IM3OS can be associated with significant mortality and morbidity. Prospective studies are needed to understand the optimal approach to diagnose and manage these patients and to develop biomarkers to predict the occurrence and severity of this rare but serious condition.
IMPLICATIONS FOR PRACTICE
Clinicians should suspect coexisting myositis and/or myasthenia gravis in all patients with immune checkpoint inhibitor-induced myocarditis, given their propensity to occur together. Early recognition and prompt treatment with the help of a multidisciplinary team might help improve the outcomes of this life-threatening condition.

Review
PURPOSE
Complications of anesthesia for pediatric radiation therapy are imperative for both radiation oncologists and anesthesiologists to clinically assess and manage. We performed the first systematic review to date addressing this important issue.
METHODS
A systematic search of PubMed and EMBASE was conducted using Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Searches were not restricted based on publication date. Nine original investigations were identified, analyzed, and collated for this report.
RESULTS
General anesthesia has proven superior to conscious sedation with regard to maintaining satisfactory procedural sedation while maintaining low respiratory and cardiovascular complication rates. Although agents such as ketamine (complication rates approaching 23%-24%) have been used in the past, other agents such as propofol and volatile anesthetics have lower complication rates because of improved drug side effect profiles (0.01%-3.5%). Most common complications are respiratory-based (eg, airway obstruction, broncho/laryngospasm, desaturation, apnea), followed by those that are cardiovascular-based (eg, tachy/bradycardia, arrhythmias, hypotension) and nausea/vomiting. Though procedure duration and anesthetic dose can be associated with higher complication risks, prior or concurrent chemotherapy does not confer added risks other than neutropenia-related sepsis. Other potential complications include those with vascular access devices, observed in up to 20% to 25%, with peripherally inserted central catheters having the highest rates of vascular complications and port catheters the lowest.
CONCLUSIONS
Rates of anesthetic complications encountered in pediatric radiation therapy are similar, if not lower, than rates reported in controlled operating room settings, implying that anesthesia for pediatric radiation therapy is safe, with low complication rates periprocedurally. Propofol infusion and oxygen delivery via nasal cannula offer the lowest immediate anesthetic complication rates and are hence most recommended for use. Though the long-term neurocognitive consequences of multiple anesthetics in pediatric patients have yet to be clearly defined, health care providers should be cognizant of the potentially serious implications.

Meta-Analysis Review
Prostate cancer is the second most common cause of cancer-related mortality in men. In patients undergoing a failure after radical treatment, one of the therapeutic option is androgen deprivation: despite initial response rates, a progression to a state of castration resistance is observed in most of the patients. In the present article, we conducted a systematic review and meta-analysis of all clinical trials assessing treatment for nmCRPC with next-generation androgen receptor inhibitors. We performed a review and meta-analysis of phase III randomized controlled trials comparing new agents (apalutamide, enzalutamide, darolutamide) with placebo as control arm, in the setting of nmCRPC. Patients treated with next-generation ARIs had a 26% reduction in the risk of death compared with placebo; compared with other ARIs, darolutamide had the lowest rate of grade 3 and 4 AEs and the lowest therapy discontinuation rate due to any grade AEs. This meta-analysis shows that treatment with new ARIs is safe and significantly reduces the risk of death and of metastasis onset in nmCRPC patients. Under way studies on new biomarkers such as genomic classifiers will probably allow the stratification in more specific subsets of disease. New imaging modalities such as PSMA-PET have shown greater sensibility and specificity than conventional imaging in metastases detection. All patients were randomized in a 2:1 fashion, with a total of 2,694 who underwent next-generation ARIs (806 apalutamide, 955 darolutamide, 933 enzalutamide) and 1,423 in the placebo arm.

Review
BACKGROUND
Historically, radiation oncologists have been cautious about re-irradiating brain tumors because of concerns about the risks of late central nervous system (CNS) toxicity, especially radionecrosis, that may occur several months to years following treatment. Today there are still limited prospective data addressing this approach.
MATERIALS AND METHODS
Systematic review of published trials reporting clinical results after re-irradiation of patients with different types of brain tumors was performed.
RESULTS
Data mainly related to glioblastoma, anaplastic glioma, medulloblastoma, ependymoma and meningioma have been published. Randomized studies are scarce. As in first-line scenarios, efficacy of radiotherapy is influenced by histology. Based on the reported outcomes, preliminary recommendations for dose/fractionation regimens can be given.
CONCLUSION
Re-irradiation of brain tumors is increasingly considered as our understanding of brain tolerance to radiation evolves and developments in radiation technology and imaging make highly accurate targeting of recurrent tumors possible. With developments in systemic therapy, further exploration of the role of re-irradiation on its own or in combination with novel agents is needed.

Meta-Analysis Review
OBJECTIVE
High mortality from cancer and rising patient numbers can trigger distress among oncologists because of a heavy and emotionally demanding workload. This systematic review and meta-analysis assesses the prevalence of high levels of distress among oncologists.
METHODS
The Preferred Reporting Items for Systematic Reviews and Meta-Analyses protocol is registered at the PROSPERO international prospective register (ref. 2015:CRD42015016325). We categorised data items according to the following distress factors: burnout, psychiatric morbidity, stress, depression, disrupted sleep, stress-induced physical symptoms, and substance use. We meta-analysed the prevalence of burnout and psychiatric morbidity using random effects models with MetaXL software.
RESULTS
The meta-analyses showed that 32% of 4876 oncologists had high burnout (±CI 28%-36%) and 27% of 2384 had high psychiatric morbidity (±CI 23%-32%). Studies also showed that 42% to 69% feel stressed at work, >12% of oncologists screen positive for depression, many oncologists suffer from sleep deprivation, up to 30% drink alcohol in a problematic way, and up to 20% of junior oncologists use hypnotic drugs, and some frequently experience stress-induced complaints such as ulcers, gastric problems, headaches, and arrhythmia.
CONCLUSIONS
Occupational distress reduces career satisfaction, affects patient care, and increases the chances of oncologists switching to another area of medicine; therefore, future research should explore appropriate interventions.
