Assessing the Theoretical Efficacy of Combination Therapy Against Gram-Negative Infections in Neutropenic Pediatric Cancer Patients: Insights from the Statistical Analysis of Survey Data.

: Empirical antibacterial therapy for febrile neutropenia reduces mortality due to Gram-negative blood stream infections (BSIs). Pediatric guidelines recommend monotherapy with an antipseudomonal beta-lactam or a carbapenem and to add a second anti-Gram-negative agent in selected situations. We evaluated the changes in the proportions of resistance of beta-lactam monotherapies vs.

Letermovir for Cytomegalovirus infection in pediatric patients undergoing allogenic hematopoietic stem cell transplantation: a real-life study by the Infectious Diseases Working Group of Italian Association of Pediatric Hematology-Oncology (AIEOP).

Letermovir prophylaxis revolutionized the approach to Cytomegalovirus infection in adult hematopoietic stem cell transplant (HCT), while data in pediatric setting are still lacking. We retrospectively analyzed 87 HCT children transplanted in 11 AIEOP centers receiving letermovir as off-label indication between January 2020 and November 2022. Letermovir was used as primary, secondary prophylaxis or CMV treatment in 39, 26 and 22 cases, respectively; no discontinuation due to toxicity was reported.

Use of music therapy in pediatric oncology: an Italian AIEOP multicentric survey study in the era of COVID-19.

Unlabelled: Music therapy (MT) is a complementary therapy offered to children, young adults, and their families in pediatric oncology and palliative care. We performed a survey to collect information about MT in pediatric oncology in Italy. The outbreak of COVID-19 unavoidably changed the scenario of MT, suggesting some considerations presented in this survey.

High-Risk Acute Myeloid Leukemia: A Pediatric Prospective.

Pediatric acute myeloid leukemia is a clonal disorder characterized by malignant transformation of the hematopoietic stem cell. The incidence and the outcome remain inferior when compared to pediatric ALL, although prognosis has improved in the last decades, with 80% overall survival rate reported in some studies. The standard therapeutic approach is a combined cytarabine and anthracycline-based regimen followed by consolidation with allogeneic stem cell transplantation (allo-SCT) for high-risk AML and allo-SCT for non-high-risk patients only in second complete remission after relapse.

Consensus on COVID-19 Vaccination in Pediatric Oncohematological Patients, on Behalf of Infectious Working Group of Italian Association of Pediatric Hematology Oncology.

Vaccines represent the best tool to prevent the severity course and fatal consequences of the pandemic by the new Coronavirus 2019 infection (SARS-CoV-2). Considering the limited data on vaccination of pediatric oncohematological patients, we developed a Consensus document to support the Italian pediatric hematological oncological (AIEOP) centers in a scientifically correct communication with families and patients and to promote vaccination. The topics of the Consensus were: SARS-CoV-2 infection and disease (COVID-19) in the pediatric subjects; COVID-19 vaccines (type, schedule); who and when to vaccinate; contraindications and risk of serious adverse events; rare adverse events; third dose and vaccination after COVID-19; and other general prevention measures.

Antibiotic Resistant Bloodstream Infections in Pediatric Patients Receiving Chemotherapy or Hematopoietic Stem Cell Transplant: Factors Associated with Development of Resistance, Intensive Care Admission and Mortality.

Bloodstream infections (BSI) are a severe complication of antineoplastic chemotherapy or hematopoietic stem cell transplantation (HSCT), especially in the presence of antibiotic resistance (AR). A multinational, multicenter retrospective study in patients aged ≤ 18 years, treated with chemotherapy or HSCT from 2015 to 2017 was implemented to analyze AR among non-common skin commensals BSI. Risk factors associated with AR, intensive care unit (ICU) admission and mortality were analyzed by multilevel mixed effects or standard logistic regressions.

Posaconazole delayed-release tablets in paediatric haematology-oncology patients.

Background: To date, there are few studies that describe pharmacokinetics, safety and efficacy of posaconazole delayed-release tablet (DRT) formulation in the paediatric population.

Objectives: We evaluated retrospectively posaconazole plasma concentrations and safety of posaconazole DRT in paediatric haematology-oncology patients.

Patients And Methods: Posaconazole DRT was assessed in 28 haematological paediatric patients with a median age 15 of years (range 5-18) and a median body weight of 50 kg (range 22-83 kg).

A comparative effectiveness trial of two faecal immunochemical tests for haemoglobin (FIT). Assessment of test performance and adherence in a single round of a population-based screening programme for colorectal cancer.

Aim: To compare acceptability and diagnostic accuracy of a recently available faecal immunochemical test (FIT) system (HM-JACKarc) with the FIT routinely used in an established screening programme (OC-Sensor).

Design: Randomised controlled trial (ISRCTN20086618) within a population-based colorectal cancer (CRC) screening programme. Subjects eligible for invitation in the Umbria Region (Italy) programme were randomised (ratio 1:1) to be screened using one of the FIT systems.

Cervical human papilloma virus (HPV) DNA primary screening test: Results of a population-based screening programme in central Italy.

Objective To present the results of the first and second round human papilloma virus (HPV)-based screening programme in the Umbria region after three years. Methods From August 2010 to November 2011, the entire female population aged 35-64 in a local health district was invited for HPV testing (HPV-DNA cobas4800 on a liquid-based cytology sample). HPV-negative women were re-invited after three years.

Use of Cytology, E6/E7 mRNA, and p16INK4a-Ki-67 to Define the Management of Human Papillomavirus (HPV)-Positive Women in Cervical Cancer Screening.

Objectives: We measured the accuracy of p16(INK4a)-Ki67 (CINtec PLUS, Roche, Mannheim, Germany), and E6/E7mRNA (types 16/18/31/33/45 NucliSENS easyQ, bioMérieux, Boxtel, The Netherlands) as triage test, alone and combined with cytology.

Methods: Six thousand two hundred and seventy two women were recruited in a population-based screening using HPV DNA as primary test; 396 were positive and were tested for cytology and biomarkers. All tests were performed on the same sample.

Role of p16(INK4a) cytology testing as an adjunct to enhance the diagnostic specificity and accuracy in human papillomavirus-positive women within an organized cervical cancer screening program.

Objective: We evaluated the performance of cytologic p16(INK4a) (p16) immunostaining within a cervical cancer screening program for the categories of atypical squamous cells of undetermined significance (ASC-US) and low-grade squamous intraepithelial lesion (LS after triage with high-risk human papillomavirus (HR-HPV) testing and atypical squamous cells, cannot exclude high-grade intraepithelial squamous lesion (ASC-H) and high-grade squamous intraepithelial lesion (HSIL). We also verified whether the routine introduction of p16 staining might enhance the specificity and positive predictive value (PPV) for cervical intraepithelial neoplasia grade 2 or higher (CIN2+) lesions predicted by a cytological screening test.

Study Design: Performance of the p16 cytology test was estimated in 578 cytological samples, of which 213 were HR-HPV+ ASC-US, 186 were HR-HPV+ LSIL, 74 were ASC-H, 56 were HSIL-CIN2 and 49 were HSIL-CIN3.

Objective: To evaluate the FocalPoint Location-Guided Screening (FPGS) performance in computer-assisted primary screening of Papanicolaou-stained cervicovaginal smears.

Study Design: A total of 37,306 routine consecutive conventional Pap slides were prospectively processed on the FPGS. Each slid designated by the instrument as Review was reported according to results obtained using a GS Review Station.

Age has no influence on mobilization of peripheral blood stem cells in acute myeloid leukemia.

The upper age limit for autologous stem cell transplantation (ASCT) in acute myeloid leukemia (AML) is increasing and peripheral blood (PB) represents the standard source of stem cell (SC). However, no data are available on the impact of age on SC mobilization in AML. We analyzed a cohort of 150 consecutive AML patients in first complete remission in order to make a comparison between patients up to 60 years and above 60 years, by evaluating CD34+ cells mobilization into PB and the number of leukapheresis needed to collect at least one single SC graft.

HFE gene mutations in patients with acute leukemia.

An increased incidence of HFE gene mutations has been described in hematologic malignancies. In the present study, we investigated the allelic frequency of HFE gene mutations in 154 adult patients with acute leukemia (AL) [107 acute myeloid leukemia (AML), 20 acute promyelocytic leukemia (APL) and 27 acute lymphoblastic leukemia (ALL)]. The allelic frequency of the H63D mutation was 29% in AL patients and 25% in the healthy controls [P = 0.

Myeloablative chemotherapy followed by autologous stem cell infusion may overcome the adverse prognostic impact of FLT3 (foetal liver tyrosine kinase 3) mutations in patients with acute myeloid leukaemia and normal karyotype.

In this study, we analysed the prognostic relevance of foetal liver tyrosine kinase 3 (FLT3) mutations in 73 patients with acute myeloid leukaemia (AML) with normal karyotype, who survived induction and consolidation and received autologous stem cell transplantation (ASCT) after successful mobilization of peripheral blood stem cell (PBSC). There were 44 males and 29 females with a median age of 54 years (range 20-77). Overall, 16 out of 73 autografted patients (22%) had FLT3 mutations.

Feasibility of autologous peripheral blood stem cell transplantation in elderly patients with acute myeloid leukemia.

Most studies showing that autologous stem cell transplantation (ASCT) is feasible in older patients with acute myeloid leukemia (AML) referred to highly selected patients considered as eligible after complete remission (CR) achievement and bone marrow or peripheral blood stem cell (PBSC) collection. This study evaluated the feasibility of ASCT from 155 consecutive AML patients aged over 60 years (median age 72 years, range 61 - 94) programmed to receive ASCT by using PBSCs after CR achievement. Overall, 90 out of 155 patients (58%) were judged as eligible for aggressive chemotherapy and 45 (50%) achieved CR.

Presence of FLT3 mutations does not impair stem cell mobilization and feasibility of autologous peripheral blood stem cell transplantation in acute myeloid leukemia.

Fetal liver tyrosine kinase 3 (FLT3) mutations represent a powerful prognostic indicator in acute myeloid leukemia (AML). Further, interaction between FLT3 and its ligand plays a role in normal hematopoiesis. Accordingly, FLT3 mutations may affect mobilization of peripheral blood stem cells (PBSCs) and feasibility of autologous stem cell transplantation (ASCT) in AML.

Therapeutic results in patients with relapsed diffuse large B cell Non-Hodgkin's lymphoma achieving complete response only after autologous stem cell transplantation.

Forty patients with relapsed diffuse large B cell lymphoma (DLBCL) autografted in partial response (PR) (n = 23) or in refractory relapse (RR) (n = 17) achieved complete remission (CR) after autologous stem cell transplantation (ASCT). Salvage treatment consisted of ifosphamide, epirubicin and etoposide (IEV) in 33 patients and Cisplatinum, ARA-C and dexamethasone (DHAP) in 7 patients. All PR and 8 RR patients were conditioned with BEAM, while 9 RR cases received the BCV regimen.

Vinorelbine plus intermediate dose cyclophosphamide is an effective and safe regimen for the mobilization of peripheral blood stem cells in patients with multiple myeloma.

High dose cyclophosphamide (HD-Cy) is commonly used to mobilize stem cells in multiple myeloma (MM). However, timing of collection is variable and incidence of side effects is substantial. We evaluated a combination of vinorelbine (VNB) (25 mg/m(2) day 1) plus Cy (1.

Ifosfamide, epirubicin and etoposide (IEV) regimen as salvage and mobilization therapy for refractory or early relapsing patients with aggressive non-Hodgkin's lymphoma.

The prognosis of early relapsing or refractory aggressive non-Hodgkin's lymphoma (NHL) is still poor. Effective salvage therapy should be able to induce high response rate as well as to mobilize hematopoietic precursors. A combination of ifosfamide, epirubicin and etoposide (IEV) was given to 28 patients with refractory or relapsing high grade NHL (4 lymphoblastic lymphoma and 24 large cell lymphoma).

Outpatient-based peripheral blood stem cell transplantation for patients with multiple myeloma.

Introduction: There is a growing demand for autologous stem cell transplantation (ASCT) in newly diagnosed patients with multiple myeloma (MM), resulting in an increasing pressure on available hospital beds. In addition, more rational utilization of health resources should induce physicians to attempt therapeutic strategies aiming at reduction of costs. The aim of this study was to explore the feasibility and safety of performing ASCT on an outpatient basis, according to an early discharge method.

Fludarabine plus cyclophosphamide for the treatment of advanced chronic lymphocytic leukemia.

Objectives: Therapeutic results in advanced chronic lymphocytic leukemia (CLL) are still unsatisfactory in terms of complete remission achievement and duration, in spite of the extensive use of purine analogs. The objective of this study was to describe the clinical characteristics and treatment results from a series of 32 patients managed with a therapeutic program based on the combination of fludarabine and cyclophosphamide (CTX).

Methods: Thirty-two patients (median age 63 yr, range 42-75 yr) with newly diagnosed (47%) or refractory-relapsed (53%) CLL were programmed to receive six courses of a 3-d combination of fludarabine at 30 mg/m2/d plus CTX at 300 mg/m2/d.
