RESUMO

Chronic lymphocytic leukemia (CLL) therapies differ in efficacy, side effects, route, frequency, and duration of administration. We assessed patient preferences for treatment attributes and evaluated associations with disease stage, treatment line, and socio-demographic characteristics in a cross sectional, observational study conducted at 16 Italian hematology centers. Study visits occurred between February and July 2020; 401 adult patients with CLL (201 Watch and Wait (W&W), 200 treated) participated in a discrete choice experiment (DCE), composed of 8 choices between pairs of treatment profiles with different levels of 5 attributes of currently available CLL treatments (length of response, route and duration of administration, risk of side effects including diarrhea, infections, or organ damage). Health-related quality of life was assessed with the EQ-5D-5L, EORTC QLQ-C30 and QLQ CLL-16. Previously treated patients had longer disease duration (7 vs. 5 years), higher prevalence of serious comorbidities (45.5% vs. 36.2%) and high-risk molecular markers (unmutated IGHV 55.6% vs. 17.1%; TP53 mutation 15.2% vs. 4.0%). Health-related quality of life scores were similar between groups. In the DCE, W&W patients rated "possible occurrence of infections" highest (relative importance [RI] = 36.2%), followed by "treatment and relevant duration" (RI = 28.0%) and "progression-free survival (PFS)" (RI = 16.9%). Previously treated patients rated "treatment and relevant duration" highest (RI = 33.3%), followed by "possible occurrence of infections" (RI = 28.8%), "possible occurrence of organ damage" (RI = 19.4%), and "PFS" (RI = 9.8%). Concern over infection was rated highest overall; unexpectedly PFS was not among the most important criteria in either group, suggesting that the first COVID-19 pandemic wave may have influenced patient preferences and concerns about CLL therapy options.

RESUMO

INTRODUCTION: Age has historically been considered the main criterion to determine eligibility for intensive chemotherapy in patients with acute myeloid leukemia (AML), but age alone can no longer be considered an absolute indicator in determining which patients should be defined as unfit. Assessment of fitness for a given treatment today serves an important role in tailoring therapeutic options. AREAS COVERED: This review examines the main options used in real life to define eligibility for intensive and nonintensive chemotherapy in patients with AML, with a main focus on the Italian SIE/SIES/GITMO Consensus Criteria. Other published real-life experiences are also reviewed, analyzing the correlation between these criteria and short-term mortality, and thus expected outcomes. EXPERT OPINION: Assessment of fitness is mandatory at diagnosis to tailor treatment to the greatest degree possible, evaluating the patient's individual profile. This is especially relevant when considering the availability of newer, less toxic therapeutic regimens, which have shown promising results in patients with AML who are older or considered unfit for intensive treatment. Fitness assessment is now a fundamental part of AML management and a critical step that can potentially influence outcomes and not just predict them.


In patients with acute myeloid leukemia (AML), age has generally been considered as the main factor to determine if intensive chemotherapy can be carried out (fitness). However, this has been gradually changing in recent years. In addition to age, comorbidities and overall performance status are also important in determining if the patient should undergo intensive chemotherapy and have an important role in tailoring therapeutic options. Consensus criteria to define eligibility for intensive and nonintensive chemotherapy in patients with AML have been proposed, which have been shown to correlate well with expected outcomes. Today, given the evolution of the treatment armamentarium, assessment of a patient's 'fitness' is compulsory to select the most appropriate treatment for each patient.

RESUMO

Chronic lymphocytic leukemia (CLL) is the most common form of adult leukemia in the western world. In Italy, venetoclax was approved for use in patients with CLL as monotherapy in 2017 and in combinations in 2019. As a result of this delayed approval, there are relatively few real-world studies from Italian clinical practice and much of the data are in heavily pretreated patients. We have collected the available studies in Italian routine practice. Three studies confirm the effectiveness and tolerability of this agent in patients with relapsed/refractory CLL and high-risk disease characteristics, many of whom had received prior B-cell receptor signaling treatment. Addition of rituximab to venetoclax produced more complete responses in patients with relapsed/refractory CLL, while higher disease burden and progression while receiving a prior Bruton's tyrosine kinase inhibitor were both associated with poorer outcomes in patients treated with venetoclax. Venetoclax was well-tolerated with low discontinuation rates. No studies of venetoclax plus obinutuzumab for the first-line treatment of patients with CLL were available due to the short time since approval in Italy. Several cohorts addressed the impact of COVID-19 on patient management and outcomes, suggesting that treated patients and those in clinical observation had similar rates of COVID-19-related hospital admission, intensive care unit admission, and mortality. Overall, the responses and tolerance to venetoclax observed in the Italian real-world setting confirm the tolerability and effectiveness of venetoclax regimens in high-risk patients.

RESUMO

Enormous advances have been made in the understanding and treatment of human epidermal growth factor receptor 2-positive breast cancer (HER2+ BC) in the last 30 years that have resulted in survival gains for affected patients. A growing body of evidence suggests that hormone receptor-positive (HR+)/HER2+ BC and HR-negative (HR-)/HER2+ BC are biologically different, with complex molecular bidirectional crosstalk between the estrogen receptor and HER2 pathway potentially affecting sensitivity to both HER2-targeted and endocrine therapy in patients with HR+/HER2+ BC. Subgroup analyses from trials enrolling patients with HER2+ BC and the results of clinical trials specifically designed to evaluate therapy in patients with HR+/HER2+ BC are helping to guide treatment decisions. In this context, encouraging results with strategies aimed at delaying or reversing drug resistance, including extended adjuvant therapy and the addition of drugs targeting alternative pathways, such as cyclin-dependent kinase (CDK) 4 and 6 inhibitors, have recently emerged. We have reached the point where tailoring the treatment according to risk and biology has become the paradigm in early BC. However, further clinical trials are needed that integrate translational research principles and identify and consider specific patient subgroups and biomarkers.

RESUMO

Sarcomas are rare malignant neoplasms that develop from mesenchymal cells and include a heterogeneous and large group of histological subtypes that may occur at any anatomical site. Soft tissue sarcomas (STS), the focus of this review, account for ≈70‒80% of sarcomas and represent <1% of all cancers. The heterogeneity of STS applies to both their topography and morphology, and 5-year survival can vary widely depending on disease stage and the complex interplay between anatomical site and histology for different STS subtypes. The rarity and heterogeneity of STS, together with other factors, such as the lack of clinical expertise often lead to difficulties and delays in making an accurate diagnosis and to the inappropriate management of each STS subtype. Therefore, this group of cancers requires special attention and approaches to diagnosis and treatment. Epidemiological data on STS are limited, and concerns have been raised regarding accurate registration of STS in cancer registries, including issues related to details of the histotypes. This review provides an overview of the epidemiology of STS in Italy, focusing on data from the Italian Association of Cancer Registries (AIRTUM), and compares findings with those from other European countries. Based on these data, and considering that STS is among the most common group of rare cancers, the relevance of multidisciplinary care for STS patients through reference centres, clinical networks and collaborative disease-specific groups is discussed.

RESUMO

INTRODUCTION: The medical treatment of patients suffering from myelodysplastic syndromes has significantly changed during the last ten years, and this may have impacted the epidemiology of infectious complications. Some 'real world' experiences raised the issue of infections in this setting and the possible negative consequences for patients and health system: the higher the rate of hospitalizations and need for anti-infective therapies, the higher the treatment delays/withdrawal and consecutive the worse the outcome. AREAS COVERED: The main epidemiological data on myelodysplastic patients are reviewed. Potential risk factors are described, including those related to the disease itself, patient's characteristics, health conditions and the environment. Expert commentary: The complexity of MDS treatment is expected to increase further, with the introduction of other drugs and combined therapies. Defining the level of risk at time of treatment prescription will become more and more important, in order to better manage the infectious risk and the febrile events eventually occurring.

RESUMO

Correct definition of the level of risk of invasive fungal infections is the first step in improving the targeting of preventive strategies. We investigated the potential relationship between pre-hospitalization exposure to sources of fungi and the development of invasive fungal infections in adult patients with newly diagnosed acute myeloid leukemia after their first course of chemotherapy. From January 2010 to April 2012, all consecutive acute myeloid leukemia patients in 33 Italian centers were prospectively registered. Upon first admission, information about possible pre-chemotherapy risk factors and environmental exposure was collected. We recorded data regarding comorbid conditions, employment, hygienic habits, working and living environment, personal habits, hobbies, and pets. All invasive fungal infections occurring within 30 days after the first course of chemotherapy were recorded. Of the 1,192 patients enrolled in this study, 881 received intensive chemotherapy and were included in the present analysis. Of these, 214 developed an invasive fungal infection, including 77 proven/probable cases (8.7%). Of these 77 cases, 54 were proven/probable invasive mold infections (6.1%) and 23 were proven yeast infections (2.6%). Upon univariate analysis, a significant association was found between invasive mold infections and age, performance status, diabetes, chronic obstructive pulmonary disease, smoking, cocaine use, job, hobbies, and a recent house renovation. Higher body weight resulted in a reduced risk of invasive mold infections. Multivariate analysis confirmed the role of performance status, job, body weight, chronic obstructive pulmonary disease, and house renovation. In conclusion, several hospital-independent variables could potentially influence the onset of invasive mold infections in patients with acute myeloid leukemia. Investigation of these factors upon first admission may help to define a patient's risk category and improve targeted prophylactic strategies. (Clinicaltrial.gov: NCT01315925)

RESUMO

OBJECTIVES: To investigate the incidence, treatment and outcome of breakthrough invasive fungal infections (IFIs) in adult acute myeloid leukaemia (AML) patients after posaconazole prophylaxis. METHODS: From January 2010 to April 2012, all consecutive patients with newly diagnosed AML were prospectively registered at 33 participating Italian centres. All cases of IFIs occurring within 30 days after the end of the first induction chemotherapy were recorded. The strategy of antifungal treatment (empirical, pre-emptive or targeted) and the drugs used were analysed. ClinicalTrials.gov code: NCT01315925. RESULTS: In total, 1192 patients with newly diagnosed AML were enrolled in the study, of whom 510 received posaconazole prophylaxis and were included in the present analysis. Of these patients, 140 (27%) needed systemic antifungal treatment. Among the 127 evaluable cases, an empirical approach was utilized in 102 patients (80%), a pre-emptive approach in 19 patients (15%) and targeted therapy in 6 patients (5%). Only five patients died of IFIs (three in the empirical group and two in the targeted group; 4%). A critical review of IFI diagnoses at 30 days demonstrated that among the patients treated empirically, ∼30% were not affected by IFIs but rather only by fever of unidentified origin. A comparison between the empirical and the pre-emptive groups showed no significant differences regarding the attributable and overall mortalities. CONCLUSIONS: This study confirms that posaconazole prophylaxis reduces the incidence of breakthrough IFIs and does not modify the efficacy of subsequent systemic antifungal treatment, regardless of the approach (empirical or pre-emptive) or the antifungal drug used.

RESUMO

Gliotoxin (GT) belongs to the epipolythiodioxopiperazine class of toxins secreted from certain fungi including Aspergillus fumigatus, which is the most prolific producer of this secondary metabolite. Recently, enhanced amounts of GT were found in in vitro biofilm-grown A. fumigatus mycelium. To further correlate the A. fumigatus biofilm growth phenotype with the enhanced secretion of GT, a polyclonal antibody (pAb) was produced by immunizing mice against GT. By an indirect immunofluorescent assay, pAb was then able to recognize specifically GT onto A. fumigatus Af293 biofilm formed on human pulmonary epithelial cells. Then, treating Af293 biofilms with a compound which reduces the GT disulfide bonds provoked shutdown of the GT-specific immunofluorescence (IF) signals along the hyphae. To explore the potential of GT for diagnostic use, pAb was shown to react with GT on hyphae into Aspergillus culture-positive respiratory tract specimens from patients with probable invasive aspergillosis (IA) and into tissue specimens from the lungs of patients with proven IA. As the presence of fungal hyphae in clinical specimens strongly indicates the in vivo A. fumigatus growth as a biofilm, anti-GT antibodies could be a specific and sensitive diagnostic tool for detecting A. fumigatus biofilm-associated clinical infections.

RESUMO

BACKGROUND: The soluble pattern-recognition receptor known as long pentraxin 3 (PTX3) has a nonredundant role in antifungal immunity. The contribution of single-nucleotide polymorphisms (SNPs) in PTX3 to the development of invasive aspergillosis is unknown. METHODS: We screened an initial cohort of 268 patients undergoing hematopoietic stem-cell transplantation (HSCT) and their donors for PTX3 SNPs modifying the risk of invasive aspergillosis. The analysis was also performed in a multicenter study involving 107 patients with invasive aspergillosis and 223 matched controls. The functional consequences of PTX3 SNPs were investigated in vitro and in lung specimens from transplant recipients. RESULTS: Receipt of a transplant from a donor with a homozygous haplotype (h2/h2) in PTX3 was associated with an increased risk of infection, in both the discovery study (cumulative incidence, 37% vs. 15%; adjusted hazard ratio, 3.08; P=0.003) and the confirmation study (adjusted odds ratio, 2.78; P=0.03), as well as with defective expression of PTX3. Functionally, PTX3 deficiency in h2/h2 neutrophils, presumably due to messenger RNA instability, led to impaired phagocytosis and clearance of the fungus. CONCLUSIONS: Genetic deficiency of PTX3 affects the antifungal capacity of neutrophils and may contribute to the risk of invasive aspergillosis in patients treated with HSCT.

RESUMO

Several studies in mouse model of invasive aspergillosis (IA) and in healthy donors have shown that different Aspergillus antigens may stimulate different adaptive immune responses. However, the occurrence of Aspergillus-specific T cells have not yet been reported in patients with the disease. In patients with IA, we have investigated during the infection: a) whether and how specific T-cell responses to different Aspergillus antigens occur and develop; b) which antigens elicit the highest frequencies of protective immune responses and, c) whether such protective T cells could be expanded ex-vivo. Forty hematologic patients have been studied, including 22 patients with IA and 18 controls. Specific T cells producing IL-10, IFN-γ, IL-4 and IL-17A have been characterized through enzyme linked immunospot and cytokine secretion assays on 88 peripheral blood (PB) samples, by using the following recombinant antigens: GEL1p, CRF1p, PEP1p, SOD1p, α1-3glucan, ß1-3glucan, galactomannan. Specific T cells were expanded through short term culture. Aspergillus-specific T cells producing non-protective interleukin-10 (IL-10) and protective interferon-gamma (IFN-γ) have been detected to all the antigens only in IA patients. Lower numbers of specific T cells producing IL-4 and IL-17A have also been shown. Protective T cells targeted predominantly Aspergillus cell wall antigens, tended to increase during the IA course and to be associated with a better clinical outcome. Aspergillus-specific T cells could be successfully generated from the PB of 8 out of 8 patients with IA and included cytotoxic subsets able to lyse Aspergillus hyphae. Aspergillus specific T-cell responses contribute to the clearance of the pathogen in immunosuppressed patients with IA and Aspergillus cell wall antigens are those mainly targeted by protective immune responses. Cytotoxic specific T cells can be expanded from immunosuppressed patients even during the infection by using the above mentioned antigens. These findings may be exploited for immunotherapeutic purposes in patients with IA.

RESUMO

Invasive fungal infections are a frequent complication after intensive chemotherapy. The aims of this prospective study were to describe the use of antifungal therapy and to report which strategy was routinely adopted to guide the introduction of antifungal therapy. A total of 321 febrile episodes in 160 paediatric patients affected by acute leukaemia or non-Hodgkin-lymphoma were investigated. Antifungal therapy was used in 100 of 321 febrile episodes (31%), and classified as empiric in 73 episodes, diagnostic-driven in 25 episodes and targeted in 2 episodes. Switching to a second-line antifungal therapy was needed in 28 of 100 episodes (28%) and was classified as empiric in 10 episodes (36%), diagnostic-driven in 17 episodes (61%) and targeted in 1 episode (4%). In 9 of 28 episodes (32%), switching to a third-line antifungal therapy was performed and was classified as empiric in 2 episodes (22%), diagnostic-driven in 6 episodes (67%) and targeted in 1 episode (11%). Invasive fungal infections was reported in 23 of 100 episodes: confirmed in 4 episodes, probable in 8 episodes, and possible in 11 episodes. Attributable mortality was 2.8%. Antifungal therapy was still used mostly empirically, whereas as fever persisted, its modification was guided by a diagnostic-driven approach.

RESUMO

BACKGROUND: The aim of this study was to develop and validate a reliable clinical prediction rule that could be employed to identify patients at higher likelihood of mortality among those with hematological malignancies (HMs) and bacterial bloodstream infections (BBSIs). METHODS AND FINDINGS: We conducted a retrospective cohort study in nine Italian hematological units. The derivation cohort consisted of adult patients with BBSI and HMs admitted to the Catholic University Hospital (Rome) between January 2002 and December 2008. Survivors and nonsurvivors were compared to identify predictors of 30-day mortality. The validation cohort consisted of patients hospitalized with BBSI and HMs who were admitted in 8 other Italian hematological units between January 2009 and December 2010. The inclusion and exclusion criteria were identical for both cohorts, with type and stage of HMs used as matching criteria. In the derivation set (247 episodes), the multivariate analysis yielded the following significant mortality-related risk factors acute renal failure (Odds Ratio [OR] 6.44, Confidential Interval [CI], 2.36-17.57, P<0.001); severe neutropenia (absolute neutrophil count <100/mm(3)) (OR 4.38, CI, 2.04-9.43, P<0.001); nosocomial infection (OR, 3.73, CI, 1.36-10.22, P = 0.01); age ≥65 years (OR, 3.42, CI, 1.49-7.80, P = 0.003); and Charlson Comorbidity Index ≥4 (OR, 3.01, CI 1.36-6.65, P = 0.006). The variables unable to be evaluated at that time (for example, prolonged neutropenia) were not included in the final logistic model. The equal-weight risk score model, which assigned 1 point to each risk factor, yielded good-excellent discrimination in both cohorts, with areas under the receiver operating curve of 0.83 versus 0.93 (derivation versus validation) and good calibration (Hosmer-Lemshow P = 0.16 versus 0.75). CONCLUSIONS: The risk index accurately identifies patients with HMs and BBSIs at high risk for mortality; a better initial predictive approach may yield better therapeutic decisions for these patients, with an eventual reduction in mortality.

RESUMO

BACKGROUND: To analyze the efficacy of antifungal prophylaxis (AFP) with posaconazole and itraconazole in a real-life setting of patients with acute myeloid leukemia (AML) during the first induction of remission. METHODS: From January 2010 to June 2011, all patients with newly diagnosed AML were consecutively registered and prospectively monitored at 30 Italian hematological centers. Our analysis focused on adult patients who received intensive chemotherapy and a mold-active AFP for at least 5 days. To determine the efficacy of prophylaxis, invasive fungal disease (IFD) incidence, IFD-attributable mortality, and overall survival were evaluated. RESULTS: In total, 515 patients were included in the present analysis. Posaconazole was the most frequently prescribed drug (260 patients [50%]) followed by fluconazole (148 [29%]) and itraconazole (93 [18%]). When comparing the groups taking posaconazole and itraconazole, there were no significant differences in the baseline clinical characteristics, whereas there were significant differences in the percentage of breakthrough IFDs (18.9% with posaconazole and 38.7% with itraconazole, P< .001). The same trend was observed when only proven/probable mold infections were considered (posaconazole, 2.7% vs itraconazole, 10.7%, P= .02). There were no significant differences in the IFD-associated mortality rate, while posaconazole prophylaxis had a significant impact on overall survival at day 90 (P= .002). CONCLUSIONS: During the last years, the use of posaconazole prophylaxis in high-risk patients has significantly increased. Although our study was not randomized, it demonstrates in a real-life setting that posaconazole prophylaxis confers an advantage in terms of both breakthrough IFDs and overall survival compared to itraconazole prophylaxis.

RESUMO

PURPOSE OF REVIEW: The aim of the present review is to analyze the main parameters that may influence the onset of bacterial, fungal and viral infections in patients with myelodysplastic syndromes, acute myeloid leukemia and acute lymphoid leukemia. RECENT FINDINGS: The identification of factors influencing the onset of infections in high-risk patients is becoming one of the most important strategies to identify those patients who would really benefit from prophylactic and timely treatment. During the past few years several studies have been conducted to evaluate the impact of risk factors that may influence both the onset and the outcome of infections. The role of some of them is well defined (i.e. neutropenia, central venous catheters), whereas other factors are now emerging as new possible causative factors (i.e. iron overload, hospitalization). SUMMARY: Many factors have to be considered when evaluating the infectious risk in hematological patients. In current clinical practice the good knowledge of these factors may favor a better management of infectious risk, with a reduction of mortality rate.

RESUMO

We report the first known case of a breakthrough pulmonary infection caused by Aspergillus nomius in an acute myeloid leukemia patient receiving caspofungin therapy. The isolate was identified using matrix-assisted laser desorption ionization-time-of-flight mass spectrometry (MALDI-TOF MS) and sequencing-based methods. The organism was found to be fully susceptible, in vitro, to echinocandin antifungal agents.
