Foreign patients and multicultural challenges in pediatric oncology: The experience of the Istituto Nazionale dei Tumori in Milan.

This paper describes the complexity of the clinical management of foreign minors suffering from cancer, through the clinical experience of an Italian referral center. The study includes 50 patients less than 18 years (22% of the patients admitted to the unit in 2023), 32 foreigners who were Italian resident and 18 who had come to Italy specifically to receive cancer treatment. Patients who migrate for healthcare reasons often arrive at the referral center with advanced disease or relapse.

Prolonged 14-day continuous infusion of high-dose ifosfamide for patients with relapsed and refractory high-grade osteosarcoma: a retrospective multicentre cohort study.

Background: The prognosis of patients with Relapsed/Refractory Osteosarcoma (R/R OS) remains dismal without an agreement on systemic therapy. The use of High-Dose Ifosfamide (14 g/sqm) with an external pump in outpatient setting (14-IFO) in R/R OS patients is limited. This study represents the first retrospective cohort analysis focused on evaluating the activity and toxicity of 14-IFO in this setting.

Current practices of follow-up programs for childhood cancer survivors in Italy.

Introduction: Quality of life in childhood cancer survivors is largely affected by survivorship care and transition from treatment to long-term follow-up (LTFU). Referring to evidence-based recommendations, we wanted to evaluate LTFU care for survivors through a survey among the Italian Association for Pediatric Hematology-Oncology (AIEOP) centers. The project aimed to evaluate the availability of services in Italy, investigate strengths and weaknesses, analyze improvements of awareness in the field, and identify the gaps that need to be addressed by different centers.

End-of-Life transfusion support at hospice and pediatric oncology unit: Bridging the gap between benefits and therapeutic alliance.

Objectives: Although transfusion support is commonly used in oncological palliative care, there is still a paucity of literature. We examined the transfusion support provided in the terminal stage of the disease and compared the approach at a pediatric oncology unit and a pediatric hospice.

Case Description: This case series analyzed patients treated at the Fondazione IRCCS Istituto Nazionale dei Tumori di Milano (INT)'s pediatric oncology unit who died between January 2018 and April 2022.

Treating secondary malignant neoplasms: A burden of childhood cancer survivors.

Each year approximately 35,000 children and adolescents are diagnosed with cancer in Europe. Five-year survival rates have improved and now reach 80% in most European countries, thanks to a combination of chemotherapy, radiotherapy, and surgery. To date, there are more than 44,000 Italians still living several years after being diagnosed with cancer in developmental age.

Acute Kidney Injury with SARS-CoV-2 Infection in Pediatric Patients Receiving High-Dose Methotrexate Chemotherapy: A Report of Three Cases.

Background: Methotrexate is renally excreted. HDMTX (high dose-methotrexate)-induced acute kidney injury (AKI) is a non-oliguric decrease in glomerular filtration rate (GFR) heralded by an acute rise in serum creatinine. Moreover, AKI is also a frequent complication of COVID-19.

Relapse after non-metastatic rhabdomyosarcoma: The impact of routine surveillance imaging on early detection and post-relapse survival.

Background: Patients with rhabdomyosarcoma (RMS) whose disease relapses have little chance of being cured, so front-line treatments are usually followed up with surveillance imaging in an effort to detect any recurrences as early as possible, and thereby improve post-relapse outcomes. The real benefit of such routine surveillance imaging in RMS remains to be demonstrated, however. This retrospective, single-center study examines how well surveillance imaging identifies recurrent tumors and its impact on post-relapse survival.

Secondary osteosarcoma: a challenge indeed.

Background: The risk of survivors developing a secondary bone sarcoma after being treated for pediatric cancers is well established. The aim of this study was to examine the clinical characteristics and outcomes of patients with secondary osteosarcoma (SOS).

Methods: The study concerns survivors of childhood and adolescence primary neoplasms (PN) treated with chemotherapy, with or without radiotherapy and surgery, subsequently diagnosed with SOS.

Relapse after nonmetastatic rhabdomyosarcoma: Salvage rates and prognostic variables.

Background: Patients with relapsing rhabdomyosarcoma (RMS) pose a therapeutic challenge, and the survival rate is reportedly poor. We describe a retrospective series of relapsing RMS patients treated at a referral center for pediatric sarcoma, investigating the pattern of relapse, salvage rates, and factors correlating with final outcomes.

Methods: The analysis concerned 105 patients <21 years old treated from 1985 to 2020 with initially localized RMS at first relapse.

Relapsing pediatric non-rhabdomyosarcoma soft tissue sarcomas: The impact of routine imaging surveillance on early detection and post-relapse survival.

Purpose: The chances of patients with relapsing pediatric non-rhabdomyosarcoma soft tissue sarcomas (NRSTS) being cured are limited. This retrospective single-institutional study examines the potential role of routine surveillance imaging for detecting recurrent tumor, and its impact on post-relapse survival.

Methods: The analysis concerned 86 patients < 21 years old with relapsing NRSTS treated from 1985 to 2020.

Ultra Short Course Chemotherapy for Early-Stage Non-Hodgkin's Lymphoma in Children.

Early-stage non-Hodgkin's lymphomas (ES-NHL) are associated with high survival rates. To minimize the risk of long-term sequelae, the duration and intensity of chemotherapy have been progressively reduced. Between 1988 and 2018, children with ES-NHL were treated at a single institute with two subsequent protocols.

How ten-years of reirradiation for paediatric high-grade glioma may shed light on first line treatment.

Purpose: Recurrence incidence for paediatric/adolescent high-grade glioma (HGG) exceeds 80%. Reirradiation (reRT) palliates symptoms and delays further progression. Strategies for reRT are scarce: we retrospectively analysed our series to develop rational future approaches.

Metastatic rhabdomyosarcoma: Evidence of the impact of radiotherapy on survival. A retrospective single-center experience.

Background: The prognosis for patients with metastatic rhabdomyosarcoma (RMS) remains largely unsatisfactory despite the adoption of intensive multimodal therapy. To assess the role of different treatments adopted over the years, we retrospectively analyzed a cohort of patients <21 years old with metastatic RMS, treated from 1990 to 2020 at a referral center for pediatric sarcomas.

Methods: Patients were treated using a multimodal approach that included surgery, radiotherapy, and chemotherapy (both high-dose chemotherapy and maintenance therapy in some cases).

Adult-type non-rhabdomyosarcoma soft tissue sarcomas in pediatric age: Salvage rates and prognostic factors after relapse.

Purpose: Though the prognosis for patients with pediatric non-rhabdomyosarcoma soft tissue sarcomas (NRSTS) is generally good, the chances of being cured after relapse are limited. This report describes a series of relapsing NRSTS patients treated at a referral center for pediatric sarcoma, investigating the pattern of relapse, salvage rates, and factors correlating with the final outcome.

Methods: The analysis concerned 103 patients <21 years old with relapsing adult-type NRSTS treated from 1985 to 2020.

Trabectedin-irinotecan, a potentially promising combination in relapsed desmoplastic small round cell tumor: report of two cases.

Effective new drugs are urgently needed for desmoplastic small round cell tumor (DSRCT), an extremely rare and aggressive disease with a generally poor prognosis. We describe two heavily-pretreated young patients with advanced-stage DSRCT given third-line treatment with a combination of trabectedin and irinotecan, based on our preclinical data demonstrating its effect on patient-derived xenografts. This trabectedin-irinotecan treatment showed a limited toxicity.

Managing Care during the COVID-19 Pandemic: The Point of View and Fears of Pediatric Cancer Patients' Families.

(1) Background: When the COVID-19 pandemic arrived, changes had to be made to several management aspects at our Pediatric Oncology Unit. We investigated how the families perceived these changes. (2) Methods: Two questionnaires were developed at the Pediatric Oncology Unit of the Istituto Nazionale dei Tumori in Milan in order to explore how the pandemic had affected the experience of patients who had been or were being treated at our hospital, as well as their families.

Prolonged COVID-19 infection in a child with lymphoblastic non-Hodgkin lymphoma: which is the best management?

During the coronavirus disease 2019 (COVID-19) pandemic, oncologists have managed patients at higher risk of having a severe course of this infection. This raises new questions about their correct management, as well as the difficulty of distinguishing tumor/treatments complications from those related to COVID-19. We report a case of an 11-year-old boy undergoing treatment for T-cell lymphoblastic lymphoma who experienced a prolonged COVID-19 course.

Extraosseous Ewing sarcoma in children and adolescents: A retrospective series from a referral pediatric oncology center.

Background: Extraosseous Ewing sarcoma is a rare entity and less is known about its clinical behavior and optimal treatment than for its counterpart in bone. This study is a retrospective analysis on a cohort of patients <21 years treated according to a "soft tissue sarcoma approach."

Methods: The "extraosseous" origin of the tumor was established on radiological findings, based on the lack of any bone involvement.

Italian pediatric and adult oncology communities join forces for a national project dedicated to adolescents and young adults with cancer.

Adolescents and young adults with cancer have substantially different clinical and psychological needs compared to those of pediatric patients and of older adult patients. We describe the development of an Italian national project dedicated to adolescents and young adults with cancer.

Treating rare tumors with the assistance of the expert virtual consultation system: two cases of juvenile granulosa cell tumors.

Background: The lack of internationally recognized guidelines for very rare tumors, such as juvenile granulosa cell tumors (JGCTs), which are nonepithelial, unusual ovarian tumors, is a challenge for pediatric oncologists, especially in developing countries with limited resources and experience in treating rare tumors.

Methods: We report clinical data of 2 girls with JGCTs treated at the Pediatric Cancer and Blood Disorders Center of Armenia with the assistance of the EXPeRT (European Cooperative Study Group for Pediatric Rare Tumors) international cooperation panel.

Case Presentation: Two girls (16 and 15 years old) with JGCTs of the ovaries, stage Ic, underwent surgery and, with consultation through an online advisory board (http://vrt.

Langerhans cell histiocytosis in adults: a retrospective, single-center case series.

Langerhans cell histiocytosis is rare in adults, and most of what we know about its diagnosis and treatment comes from pediatric studies. We report clinical findings and results of treatment in a retrospective series of 63 consecutive adult patients (18-76 years old), treated at our pediatric unit from 1990 to 2020 using the same approach as for children. Patients were classified as having single-system disease (SS-LCH) in 41 cases, which was unifocal in 34 of them and multifocal in 7, or multisystem disease (MS-LCH) in 17 and primary pulmonary (pLCH) in 5.

Children and adolescent solid tumours and high-intensity end-of-life care: what can be done to reduce acute care admissions?

Unlabelled: Despite improvements in survival, cancer remains the leading cause of non-accidental death in children and adolescents, who risk receiving high-intensity end-of-life (HI-EOL) care.

Objective: To analyse treatments for relapses (particularly in the last weeks of life), assess their impact on the EOL, identify patients most likely to receive HI-EOL care and examine whether palliative care services can contain the intensity of EOL care.

Methods: This retrospective study involved patients treated at the paediatric oncology unit of the Istituto Nazionale Tumori in Milan who died between 2018 and 2020.

SARS-CoV-2 vaccination for adolescents and young adult patients treated at a specialist pediatric oncology unit.

This brief report describes the SARS-CoV-2 vaccination program at our pediatric oncology unit. Adopting Italian regulations, patients treated for cancer within the previous 6 months were offered vaccination with the Pfizer-BioNtech vaccine if aged ≥16 years, and with the Pfizer-BioNtech or Moderna vaccine if aged ≥18 years. From March 24 to April 28, 2021, 80/89 adolescent and young adult patients enrolled were vaccinated, while nine refused the vaccine due to fear of side effects, disbelief regarding the pandemic, or lack of trust in the scientific community.
