Purpose This study intends to translate and make any necessary cultural adaptations of the Pediatric PRO-CTCAE version for Italian oncological patients aged 7–18 years and their caregivers. Methods The questionnaire has been forward/backward translated into Italian and subjected to detailed verification by fluent Italian speakers, children and their parents, for use in clinical trials in Italian populations. The Italian version includes 130 questions that assess 62 symptoms. To verify the patients' comprehension some interviews were completed with 24 oncological children and adolescents in different age groups and 24 parents (M age  = 41.2). Caregivers were interviewed independently. Results A final Italian version of the Pediatric PRO-CTCAE was produced. Across the age range, most patients and caregivers were able to understand and answer the questions. The 7–9 years old had greater challenges completing two terms which were retested in a second round of interviews. There were no comprehension differences on the basis of trials enrollment phase. Conclusions The translation and adaptation of the Pediatric PRO-CTCAE confirms that this instrument is also suitable for assessing symptom toxicities among Italian cancer patients. Its rapid integration into care pathways is necessary to guarantee an early response to patient symptoms and to facilitate drug tolerability assessment. [ABSTRACT FROM AUTHOR]

Simple Summary: The prognosis of patients with primary disseminated multifocal Ewing sarcoma (PDMES) remains dismal. Previously, a combination of temozolomide and irinotecan (TEMIRI) was tested in patients with refractory or relapsed disease. The aim of our study was to evaluate the activity and tolerability of TEMIRI (two courses) as a front-line treatment in PDMES. With thirty-four patients enrolled, the Response Evaluation Criteria in Solid Tumors (RECIST), after TEMIRI, was acceptable with a manageable toxicity and a high percentage of patients showing an amelioration in their Eastern Cooperative Oncology Group (ECOG)/Lansky scores. TEMIRI in front-line therapy showed encouraging activity and deserves further evaluation combined with conventional treatments in non-metastatic patients; meanwhile, new treatment strategies for PDMES are urgently needed. Purpose: The main objective was to evaluate the activity and tolerability of TEMIRI as a front-line treatment in primary disseminated Ewing sarcoma (PDMES) using the RECIST 1.1 criteria. The secondary objectives included the assessment of toxicity and the performance status/symptom changes. Methods: Between 2012 and 2018, patients with PDMES received two courses of temozolomide 100 mg/sqm/day + irinotecan 50 mg/sqm/day for 5 days every 3 weeks as an amendment to the Italian Sarcoma Group/Associazione Italiana EmatoIogia ed Oncologia Pediatrica (ISG/AIEOP) EW-2 protocol (EUDRACT#2009-012353-37, Vers. 1.02). Results: Thirty-four patients were enrolled. The median age at diagnosis was 19 years (range 3–55). After TEMIRI, the RECIST response was as follows: a partial response in 20 (59%) patients, stable disease in 11 (32%), and disease progression in 3 (9%). The ECOG/Lansky score was improved in 25/34 (73.5%) cases, and a reduction or disappearance of pain was observed in 31/34 patients (91%). The incidence of grade 3–4 toxicity was 3%. The 3-year event-free survival (EFS) and overall survival (OS) were 21% (95% CI 6–35%) and 36% (95% CI: 18–54%), respectively. Conclusion: the smooth handling and encouraging activity demonstrated by up-front TEMIRI did not change the EFS in PDMES, so this result suggests the need for the further evaluation of the efficacy of TEMIRI in combination with conventional treatments in non-metastatic patients.

Osteosarcoma (OS) is a rare bone malignant tumour with a poor prognosis in the case of recurrence. So far, there is no agreement on the best systemic therapy for relapsed OS. The availability of next generation sequencing techniques has recently revolutionized clinical research. The sequencing of the tumour and its matched normal counterpart has the potential to reveal a wide landscape of genetic alterations with significant implications for clinical practice. The knowledge that the genomic profile of a patient's tumour can be precisely mapped and matched to a targeted therapy in real time has improved the development of precision medicine trials (PMTs). PMTs aiming at determining the effectiveness of targeted therapies could be advantageous for patients with a tumour refractory to standard therapies. Development of PMTs for relapsed OS is largely encouraging and is in its initial phase. Assessing OS features, such as its rarity, its age distribution, the technical issues related to the bone tissue origin, and its complex genomic landscape, represents a real challenge for PMTs development. In this light, a multidisciplinary approach is required to fully exploit the potential of precision medicine for OS patients. [ABSTRACT FROM AUTHOR]
