RESUMO

Despite widespread vaccination rates, we are living with high transmission rates of SARS-CoV-2. Although overall hospitalisation rates are falling, the risk of serious infection remains high for patients who are immunocompromised because of haematological malignancies. In light of the ongoing pandemic and the development of multiple agents for treatment, representatives from the Haematology Society of Australia and New Zealand and infectious diseases specialists have collaborated on this consensus position statement regarding COVID-19 management in patients with haematological disorders. It is our recommendation that both patients with haematological malignancies and treating specialists be educated regarding the preventive and treatment options available and that patients continue to receive adequate vaccinations, keeping in mind the suboptimal vaccine responses that occur in haematology patients, in particular, those with B-cell malignancies and on B-cell-targeting or depleting therapy. Patients with haematological malignancies should receive treatment for COVID-19 in accordance with the severity of their symptoms, but even mild infections should prompt early treatment with antiviral agents. The issue of de-isolation following COVID-19 infection and optimal time to treatment for haematological malignancies is discussed but remains an area with evolving data. This position statement is to be used in conjunction with advice from infectious disease, respiratory and intensive care specialists, and current guidelines from the National COVID-19 Clinical Evidence Taskforce and the New Zealand Ministry of Health and Cancer Agency Te Aho o Te Kahu COVID-19 Guidelines.

RESUMO

Patients with cancer demonstrate an increased vulnerability for infection and severe disease by SARS-CoV-2, the causative agent of COVID-19. Risk factors for severe COVID-19 include comorbidities, uncontrolled disease, and current line of treatment. Although COVID-19 vaccines have afforded some level of protection against infection and severe disease among patients with solid tumors and hematologic malignancies, decreased immunogenicity and real-world effectiveness have been observed among this population compared with healthy individuals. Characterizing and understanding the immune response to increasing doses or differing schedules of COVID-19 vaccines among patients with cancer is important to inform clinical and public health practices. In this article, we review SARS-CoV-2 susceptibility and immune responses to COVID-19 vaccination in patients with solid tumors, hematologic malignancies, and those receiving hematopoietic stem cell transplant or chimeric-antigen receptor T-cell therapy.

RESUMO

BACKGROUND: Patients without human immunodeficiency virus (HIV) are increasingly recognized as being at risk for cryptococcosis. Knowledge of characteristics of cryptococcosis in these patients remains incomplete. METHODS: We conducted a retrospective study of cryptococcosis in 46 Australian and New Zealand hospitals to compare its frequency in patients with and without HIV and describe its characteristics in patients without HIV. Patients with cryptococcosis between January 2015 and December 2019 were included. RESULTS: Of 475 patients with cryptococcosis, 90% were without HIV (426 of 475) with marked predominance in both Cryptococcus neoformans (88.7%) and Cryptococcus gattii cases (94.3%). Most patients without HIV (60.8%) had a known immunocompromising condition: cancer (n = 91), organ transplantation (n = 81), or other immunocompromising condition (n = 97). Cryptococcosis presented as incidental imaging findings in 16.4% of patients (70 of 426). The serum cryptococcal antigen test was positive in 85.1% of tested patients (319 of 375); high titers independently predicted risk of central nervous system involvement. Lumbar puncture was performed in 167 patients to screen for asymptomatic meningitis, with a positivity rate of 13.2% where meningitis could have been predicted by a high serum cryptococcal antigen titer and/or fungemia in 95% of evaluable cases. One-year all-cause mortality was 20.9% in patients without HIV and 21.7% in patients with HIV (P = .89). CONCLUSIONS: Ninety percent of cryptococcosis cases occurred in patients without HIV (89% and 94% for C. neoformans and C. gattii, respectively). Emerging patient risk groups were evident. A high level of awareness is warranted to diagnose cryptococcosis in patients without HIV.

RESUMO

Revaccination after receipt of a hematopoietic cell transplant (HCT) or cellular therapies is a pillar of patient supportive care, with the potential to reduce morbidity and mortality linked to vaccine-preventable infections. This review synthesizes national, international, and expert consensus vaccination schedules post-HCT and presents evidence regarding the efficacy of newer vaccine formulations for pneumococcus, recombinant zoster vaccine, and coronavirus disease 2019 in patients with hematological malignancy. Revaccination post-cellular therapies are less well defined. This review highlights important considerations around poor vaccine response, seroprevalence preservation after cellular therapies, and the optimal timing of revaccination. Future research should assess the immunogenicity and real-world effectiveness of new vaccine formulations and/or vaccine schedules in patients post-HCT and cellular therapy, including analysis of vaccine response that relates to the target of cellular therapies.

RESUMO

PURPOSE: To understand the drivers and barriers for COVID-19 vaccination in people with cancer in Australia. METHODS: A cross-sectional, online survey, distributed nationally following the establishment of community vaccination programs, wider availability of COVID-19 vaccines and emergence of new variants. Consisting of 21 questions, the survey was designed to determine the behavioural and social drivers of vaccination, participant demographics, underlying disease and treatment, and vaccination status. It was open from the 10th of August 2021 to the 7th of September 2021, recruiting people who had a previous history of cancer (diagnosed or treated in the past 5 years). RESULTS: A total of 1506 responses were included in the final analysis. Overall, 87.8% reported a positive attitude toward vaccination and 83.1% had received at least one dose of a COVID-19 vaccine. Perceived risk of COVID-19 infection (for self and others) and engagement with a trusted health professional were key drivers for vaccination, while concerns about vaccine development, safety and side effects were barriers. Concerns about vaccination mostly stemmed from a place of misinformation, rather than a broader disregard of vaccines. Just over a third (497, 34.3%) of the respondents were concerned that the vaccine would impact their cancer treatment. CONCLUSION: Overall, participants had positive attitudes toward COVID-19 vaccination and thought it was safe. Findings supported the role of health professionals and cancer organisations as trusted information providers and calls for more, credible information to help people with cancer make informed decisions about the COVID-19 vaccine.

RESUMO

Infection remains a significant contributor to morbidity and mortality in patients with myeloma. This guideline was developed by a multidisciplinary group of clinicians who specialise in the management of patients with myeloma and infection from the medical and scientific advisory group from Myeloma Australia and the National Centre for Infections in Cancer. In addition to summarising the current epidemiology and risk factors for infection in patients with myeloma, this guideline provides recommendations that address three key areas in the prevention of infection: screening for latent infection, use of antimicrobial prophylaxis and immunoglobulin replacement and vaccination against leading respiratory infections (severe acute respiratory syndrome coronavirus 2, influenza and Streptococcus pneumoniae) and other preventable infections. This guideline provides a practical approach to the prevention of infection in patients with myeloma and harmonises the clinical approach to screening for infection, use of prophylaxis and vaccination to prevent infectious complications.

RESUMO

Patients with post-haemopoietic stem cell transplant or chimeric antigen receptor T -cell (CAR-T) therapy face a significant risk of morbidity and mortality from coronavirus disease 2019 because of their immunosuppressed state. As case numbers in Australia and New Zealand continue to rise, guidance on management in this high-risk population is needed. Whilst we have learned much from international colleagues who faced high infection rates early in the pandemic, guidance relevant to local health system structures, medication availability and emerging therapies is essential to equip physicians to manage our patients optimally.

RESUMO

INTRODUCTION: Home-based treatment of febrile neutropenia (FN) in children with cancer with oral or intravenous antibiotics is safe and effective. There are limited data on the economic impact of this model of care. We evaluated the cost-effectiveness of implementing an FN programme, incorporating home-based intravenous antibiotics for carefully selected patients, in a tertiary paediatric hospital. METHODS: A decision analytic model was constructed to compare costs and outcomes of the home-based FN programme, with usual in-hospital treatment with intravenous antibiotics. The programme included a clinical decision rule to stratify patients by risk for severe infection and home-based eligibility criteria using disease, chemotherapy and patient-level factors. Health outcomes (quality of life) and probabilities of FN risk classification and home-based eligibility were based on prospectively collected data between 2017 and 2019. Patient-level costs were extracted from hospital administrative records. Cost-effectiveness was expressed as the incremental cost per quality-adjusted life year (QALY). FINDINGS: The mean health care cost of home-based FN treatment in low-risk patients was Australian dollars (A$) 7765 per patient compared to A$20,396 for in-hospital treatment (mean difference A$12,632 [95% CI: 12,496-12,767]). Overall, the home-based FN programme was the dominant strategy, being more effective (0.0011 QALY [95% CI: 0.0011-0.0012]) and less costly. Results of the model were most sensitive to proportion of children eligible for home-based care programme. CONCLUSION: Compared to in-hospital FN care, the home-based FN programme is cost-effective, with savings arising from cheaper cost of caring for children at home. These savings could increase as more patients eligible for home-based care are included in the programme.

RESUMO

BACKGROUND: High-intensity chemotherapy and advances in novel immunotherapies have seen the emergence of cytomegalovirus (CMV) infections in cancer patients other than allogeneic haemopoietic cell transplantation (HCT). Aim To evaluate the epidemiology, clinical characteristics and outcomes of CMV infection in this population. METHODS: A retrospective review of cancer patients other than allogeneic HCT who had CMV DNAemia and/or disease from July 2013 till May 2020 at a quaternary cancer centre was performed. RESULTS: Of 11 485 cancer patients who underwent treatment during this period, 953 patients had CMV DNA testing performed and 238 of them had CMV DNAemia. After excluding patients with allogeneic HCT, 62 patients with CMV DNAemia were identified, of whom 10 had concurrent CMV disease. The most frequent underlying malignancies were B-cell lymphoproliferative disease (LPD) (31%; 19/62), T-cell LPD (21%; 13/62), chronic lymphocytic leukaemia (11%; 7/62) and multiple myeloma (10%; 6/62). Most patients had lymphopenia (77%; 48/62), multiple cancer therapies (63%; 39/62 received ≥2 previous therapies), co-infection (56%; 35/62 had ≥1 co-infection) and corticosteroid therapy (48%; 30/62) within 1 month before CMV diagnosis. CMV DNAemia and disease were observed in patients receiving novel immunotherapies, including bispecific antibody therapy, chimeric-antigen receptor T-cell therapy and immune checkpoint inhibitors. CONCLUSION: Patients with haematological malignancy, particularly B-cell LPD, T-cell LPD, chronic lymphocytic leukaemia and multiple myeloma, were frequently identified to have CMV DNAemia and disease. Lymphopenia, multiple cancer therapies, co-infection and recent receipt of systemic corticosteroids were also commonly observed. Future studies are necessary to determine optimal identification and management of CMV in these patients.

RESUMO

BACKGROUND: Antimicrobial Stewardship (AMS) is a key method to tackle antimicrobial resistance (AMR). In Australia, private hospitals have a higher rate of inappropriate prescribing and non-compliance with antimicrobial guidelines, yet this phenomenon is poorly described. Private hospitals make up 49% of hospitals in Australia, making it vital to understand AMS in this setting. METHODS: This study aimed to explore capabilities, opportunities and motivations for AMR and AMS with stakeholders at an Australian private hospital, and identify barriers and enablers 5 years post-implementation of an AMS program comparing with pre-implementation findings. A mixed-methods study was performed, involving three focus groups with stakeholders. All doctors, nurses and pharmacists at the hospital were invited to complete a survey on their experiences with and awareness of AMR, AMS and antimicrobial prescribing. RESULTS: Thirteen staff took part in the focus groups, 100 staff responded to the survey. Staff understood the importance of the AMS program, but active engagement was low. Staff felt more thorough feedback and monitoring could improve prescribing behaviour, but acknowledged difficulty in private hospitals in changing habits of staff who valued autonomy in making prescribing decisions. Half of respondents felt the current AMS restrictions should continue. Executive engagement may be needed to drive system changes across a complex network. CONCLUSION: AMS awareness increased post-implementation, but staff remained sceptical of its benefits. Engagement and education of medical consultants regarding local benefits of AMS must improve. Enhanced understanding of feedback provision, methods for engagement, and advocacy from leadership will ensure success and longevity for the program.

RESUMO

BACKGROUND: Seroprotection and seroconversion rates are not well understood for 2-dose inactivated influenza vaccination (IIV) schedules in autologous hematopoietic stem cell transplantation (autoHCT) patients. METHODS: A randomized, single-blind, controlled trial of IIV in autoHCT patients in their first year post-transplant was conducted. Patients were randomized 1:1 to high-dose (HD) IIV followed by standard dose (SD) vaccine (HD-SD arm) or 2 SD vaccines (SD-SD arm) 4 weeks apart. Hemagglutination inhibition (HI) assay for IIV strains was performed at baseline, 1, 2, and 6 months post-first dose. Evaluable primary outcomes were seroprotection (HI titer ≥40) and seroconversion (4-fold titer increase) rates and secondary outcomes were geometric mean titers (GMTs), GMT ratios (GMRs), adverse events, influenza-like illness (ILI), and laboratory-confirmed influenza (LCI) rates and factors associated with seroconversion. RESULTS: Sixty-eight patients were enrolled (34/arm) with median age of 61.5 years, majority male (68%) with myeloma (68%). Median time from autoHCT to vaccination was 2.3 months. For HD-SD and SD-SD arms, percentages of patients achieving seroprotection were 75.8% and 79.4% for H1N1, 84.9% and 88.2% for H3N2 (all P > .05), and 78.8% and 97.1% for influenza-B/Yamagata (P = .03), respectively. Seroconversion rates, GMTs and GMRs, and number of ILI or LCIs were not significantly different between arms. Adverse event rates were similar. Receipt of concurrent cancer therapy was independently associated with higher odds of seroconversion (OR, 4.3; 95% CI, 1.2-14.9; P = .02). CONCLUSIONS: High seroprotection and seroconversion rates against all influenza strains can be achieved with vaccination as early as 2 months post-autoHCT with either 2-dose vaccine schedules.

RESUMO

PURPOSE OF REVIEW: This review aims to summarize available guidelines as well as the emerging evidence for the prevention and treatment of invasive fungal diseases in high-risk haematology patients. RECENT FINDINGS: Primary mould-active prophylaxis is the strategy used in many centres to manage the risk of invasive fungal disease in high-risk haematology patients, and posaconazole remains the antifungal of choice for most of these patients. Data on the use of other antifungals for primary prophylaxis, including isavuconazole, are limited. There is considerable interest in identifying a strategy that would limit the use of mould-active agents to the patients who are the most likely to benefit from them. In this regard, a recent trial demonstrated that the preemptive strategy is noninferior to the empiric strategy. For primary treatment of invasive aspergillosis, two randomized trials found isavuconazole and posaconazole to be noninferior to voriconazole. Isavuconazole does not appear to require therapeutic drug monitoring. SUMMARY: Prophylaxis and treatment of invasive fungal diseases in high-risk haematology patients is a rapidly evolving field. Critical clinical questions remain unanswered, especially regarding the management of suspected invasive fungal diseases breaking through mould-active prophylaxis, and the duration of antifungal therapy for invasive mould infections.

RESUMO

PURPOSE: Contention surrounds how best to screen patients for latent and undiagnosed infection prior to cancer treatment. Early treatment and prophylaxis against reactivation may improve infection-associated morbidity. This study sought to examine rates of screening and prevalence of latent infection in overseas-born patients receiving cancer therapies. METHODS: A single-centre retrospective audit of 952 overseas-born patients receiving chemotherapy, targeted agents and immunotherapy between January 1 and December 31 2019 was undertaken at Peter MacCallum Cancer Centre. Pre-treatment screening for hepatitis B (HBV), hepatitis C (HCV), human immunodeficiency virus (HIV), latent tuberculosis (LTBI), toxoplasmosis and strongyloidiasis was audited. RESULTS: Approximately half of our overseas-born patients were screened for HBV (58.9%) and HCV (50.7%). Fewer patients were screened for HIV (30.5%), LTBI (18.3%), strongyloidiasis (8.6%) or toxoplasmosis (8.1%). Although 59.7% of our patients were born in countries with high epidemiological risk for latent infection, according to World Health Organization data, 35% were not screened for any infection prior to commencement of therapy. CONCLUSION: The prevalence of latent infections amongst overseas-born patients with cancer, and complexities associated with risk-based screening, likely supports universal latent infection screening amongst this higher-risk cohort.

RESUMO

BACKGROUND: Home-based management of low-risk febrile neutropenia (FN) is safe, improves quality of life and reduces healthcare expenditure. A formal low-risk paediatric program has not been implemented in Australia. We aimed to describe the implementation process and evaluate the clinical impact. METHOD: This prospective study incorporated three phases: implementation, intervention and evaluation. A low-risk FN implementation toolkit was developed, including a care-pathway, patient information, home-based assessment and educational resources. The program had executive-level endorsement, a multidisciplinary committee and a nurse specialist. Children with cancer and low-risk FN were eligible to be transferred home with a nurse visiting daily after an overnight period of observation for intravenous antibiotics. Low-risk patients were identified using a validated decision rule, and suitability for home-based care was determined using disease, chemotherapy and patient-level criteria. Plan-Do-Study-Act methodology was used to evaluate clinical impact and safety. RESULTS: Over 18 months, 292 children with FN were screened: 132 (45%) were low-risk and 63 (22%) were transferred to home-based care. Compared with pre-implementation there was a significant reduction in in-hospital median LOS (4.0 to 1.5 days, p < 0.001) and 291 in-hospital bed days were saved. Eight (13%) patients needed readmission and there were no adverse outcomes. A key barrier was timely screening of all patients and program improvements, including utilising the electronic medical record for patient identification, are planned. CONCLUSION: This program significantly reduces in-hospital LOS for children with low-risk FN. Ongoing evaluation will inform sustainability, identify areas for improvement and support national scale-up of the program.

RESUMO

Antifungal prophylaxis can reduce morbidity and mortality from invasive fungal disease (IFD). However, its use needs to be optimised and appropriately targeted to patients at highest risk to derive the most benefit. In addition to established risks for IFD, considerable recent progress in the treatment of malignancies has resulted in the development of new 'at-risk' groups. The changing epidemiology of IFD and emergence of drug resistance continue to impact choice of prophylaxis, highlighting the importance of active surveillance and knowledge of local epidemiology. These guidelines aim to highlight emerging risk groups and review the evidence and limitations around new formulations of established agents and new antifungal drugs. It provides recommendations around use and choice of antifungal prophylaxis, discusses the potential impact of the changing epidemiology of IFD and emergence of drug resistance, and future directions for risk stratification to assist optimal management of highly vulnerable patients.

RESUMO

Australia and New Zealand have achieved excellent community control of COVID-19 infection. In light of the imminent COVID-19 vaccination roll out in both countries, representatives from the Haematology Society of Australia and New Zealand and infectious diseases specialists have collaborated on this consensus position statement regarding COVID-19 vaccination in patients with haematological disorders. It is our recommendation that patients with haematological malignancies, and some benign haematological disorders, should have expedited access to high-efficacy COVID-19 vaccines, given that these patients are at high risk of morbidity and mortality from COVID-19 infection. Vaccination should not replace other public health measures in these patients, given that the effectiveness of COVID-19 vaccination, specifically in patients with haematological malignancies, is not known. Given the limited available data, prospective collection of safety and efficacy data of COVID-19 vaccination in this patient group is a priority.

RESUMO

INTRODUCTION: A multi-centre study to determine the outcomes and risks for invasive fungal disease (IFD) in myeloma (MM) patients treated with second-generation immunomodulatory drugs, proteasome inhibitors and monoclonal antibodies was conducted. METHODS: Clinical and microbiology records were reviewed to capture patient demographics, disease characteristics, treatment, IFD episodes and outcomes. Categorical and continuous variables between patients with IFD and without IFD were compared using chi-square test, Fisher's exact test and Mann-Whitney rank sum test, respectively, with P-value < .05 considered statistically significant. RESULTS: Five out of 148 (3.4%) MM patients were diagnosed with five episodes of IFI: 3 were proven, 1 probable and 1 possible. Median time from commencement of new generation therapy to IFD diagnosis was 4.0 months (Interquartile range [IQR]: 3.4-5.7). In patients with IFD, median cumulative steroid dose over 60 days was 1119 mg (IQR: 1066-1333 mg). None of the patients with IFD had prolonged neutropenia (neutrophil count < 0.5 × 109 /L for more than 10 days). Common sites of infection were the respiratory tract (40.0%) and bloodstream (40.0%). Cryptococcus neoformans (n = 2) and Candida krusei (n = 1) were the fungal pathogens isolated in the three proven cases. 30-day mortality rate was 40.0%. Patients with IFD were younger (median 58 versus 68 years, P = .52) and treated with more lines of therapy (median 5 vs 3, P = .04). CONCLUSION: IFD rate is low in heavily treated MM patients treated with second-generation therapy including monoclonal antibodies. Patients do not appear to have traditional risk factors such as prolonged neutropenia.

RESUMO

BACKGROUND: Vancomycin-resistant enterococcus (VRE) is an important cause of infection in immunocompromised populations. Few studies have described the characteristics of vanB VRE infection. We sought to describe the epidemiology, treatment and outcomes of VRE bloodstream infections (BSI) in a vanB predominant setting in malignant hematology and oncology patients. METHODS: A retrospective review was performed at two large Australian centres and spanning a 6-year period (2008-2014). Evaluable outcomes were intensive care admission (ICU) within 48 h of BSI, all-cause mortality (7 and 30 days) and length of admission. RESULTS: Overall, 106 BSI episodes were observed in 96 patients, predominantly Enterococcus faecium vanB (105/106, 99%). Antibiotics were administered for a median of 17 days prior to BSI, and 76/96 (79%) were neutropenic at BSI onset. Of patients screened before BSI onset, 49/72 (68%) were found to be colonised. Treatment included teicoplanin (59), linezolid (6), daptomycin (2) and sequential/multiple agents (21). Mortality at 30-days was 31%. On multivariable analysis, teicoplanin was not associated with mortality at 30 days. CONCLUSIONS: VRE BSI in a vanB endemic setting occurred in the context of substantive prior antibiotic use and was associated with high 30-day mortality. Targeted screening identified 68% to be colonised prior to BSI. Teicoplanin therapy was not associated with poorer outcomes and warrants further study for vanB VRE BSI in cancer populations.

RESUMO

INTRODUCTION: A pandemic coronavirus, SARS-CoV-2, causes COVID-19, a potentially life-threatening respiratory disease. Patients with cancer may have compromised immunity due to their malignancy and/or treatment, and may be at elevated risk of severe COVID-19. Community transmission of COVID-19 could overwhelm health care services, compromising delivery of cancer care. This interim consensus guidance provides advice for clinicians managing patients with cancer during the pandemic. MAIN RECOMMENDATIONS: During the COVID-19 pandemic: In patients with cancer with fever and/or respiratory symptoms, consider causes in addition to COVID-19, including other infections and therapy-related pneumonitis. For suspected or confirmed COVID-19, discuss temporary cessation of cancer therapy with a relevant specialist. Provide information on COVID-19 for patients and carers. Adopt measures within cancer centres to reduce risk of nosocomial SARS-CoV-2 acquisition; support population-wide social distancing; reduce demand on acute services; ensure adequate staffing; and provide culturally safe care. Measures should be equitable, transparent and proportionate to the COVID-19 threat. Consider the risks and benefits of modifying cancer therapies due to COVID-19. Communicate treatment modifications, and review once health service capacity allows. Consider potential impacts of COVID-19 on the blood supply and availability of stem cell donors. Discuss and document goals of care, and involve palliative care services in contingency planning. CHANGES IN MANAGEMENT AS A RESULT OF THIS STATEMENT: This interim consensus guidance provides a framework for clinicians managing patients with cancer during the COVID-19 pandemic. In view of the rapidly changing situation, clinicians must also monitor national, state, local and institutional policies, which will take precedence.

RESUMO

PURPOSE OF REVIEW: With the introduction of new targeted therapies for hematological malignancies comes the challenges of both assessing the risk of developing an IFD while being treated with these agents, as well as managing the drug--drug interactions between azole antifungals and the agents. RECENT FINDINGS: New targeted therapies for hematological malignancy include chimeric antigen receptor T cells (CAR T cells), Bi-specific T-cell Engager (BiTE) blinatumomab, and the antibody-drug conjugate (ADC) of calicheamicin inotuzumab ozogamicin for acute lymphoblasic leukemia (ALL) and lymphoma; the Bruton's tyrosine kinase (BTK) inhibitor ibrutinib and phosphatidylinositol 3-kinase (PI3Kδ) inhibitor idelalisib for lymphoma and graft-versus-host disease (GVHD); FMS-like tyrosine kinase 3 (FLT3) inhibitors, such as midostaurin, sorafenib and gilteritinib for acute myeloid leukemia (AML); and the BCL-2 inhibitor venetoclax for a range of hematological malignancies including lymphoma and leukemia. This review summarizes recommendations for IFD prophylaxis using these therapies and evidence for managing concomitant azole administration. SUMMARY: Whilst some evidence exists to guide IFD prophylaxis using new targeted therapies for hematological malignancies, there is an overall lack of descriptive, robust studies specifically describing IFD risk and management. With the emergence of novel agents, clinical judgment must be used to assess the risk of developing an IFD. Care must also be taken when administering azoles with drug--drug interactions, often requiring dose adjustment of the cancer therapies.
