Retrospective-perspective Observational Cohort Study on Toxicity and Efficacy of Radiotherapy in Pediatric and Adult Patients With Pediatric Histology Treated at the Pediatric Radiotherapy of the CRO in Aviano

Observational Radiation Toxicity

For patients and families

In plain language

An automatic summary of structured registry data. It is an orientation aid, not a substitute for the official protocol or a physician assessment.

What is being studied
This is an observational study: the protocol does not assign a study treatment.
Who it may be relevant to
Registry conditions: Radiation Toxicity. Basic parameters: No limits · All.
What needs checking
Age, condition and sex are only basic indicators. Prior treatment, laboratory values and other mandatory requirements appear in the eligibility criteria below.

Overview

Radiotherapy key role in pediatric oncology, despite the potential side effects especially in the long term, including the risk of radioinduced second cancers. Very rarely malignant neoplasms typical of children and adolescents may present in adulthood, historically with a worse outcome, but for some of these histologies demonstrated recent results overlapping with those in pediatric age when treated with strategies similar to pediatric protocols and similar radiotherapy. Long-term data on outcome and incidence of potential toxicity late radiation therapy in these populations almost exclusively from epidemiologic studies or retrospective case series. Prospective data are lacking, particularly in patients treated with IMRT and specifically with certain IMRT modalities such as Helical Tomotherapy, for which the CRO pediatric radiotherapy has documented experience. The main objective is to evaluate the short- and long-term toxicity secondary to radiotherapy performed at the Pediatric Radiotherapy of the CRO in Aviano, with specific subgroup analyses aimed at highlighting any differences mainly by age, pathology and radiotherapy technique.

Detailed description

Radiotherapy key role in pediatric oncology, despite the potential side effects especially in the long term, including the risk of radioinduced second cancers.

Very rarely malignant neoplasms typical of children and adolescents may present in adulthood, historically with a worse outcome, but for some of these histologies demonstrated recent results overlapping with those in pediatric age when treated with strategies similar to pediatric protocols and similar radiotherapy.

Long-term data on outcome and incidence of potential toxicity late radiation therapy in these populations almost exclusively from epidemiologic studies or retrospective case series. Prospective data are lacking, particularly in patients treated with IMRT and specifically with certain IMRT modalities such as Helical Tomotherapy, for which the CRO pediatric radiotherapy has documented experience.

The main objective is to evaluate the short- and long-term toxicity secondary to radiotherapy performed at the Pediatric Radiotherapy of the CRO in Aviano, with specific subgroup analyses aimed at highlighting any differences mainly by age, pathology and radiotherapy technique.

Primary outcome measures

  • Incidence of acute radiotherapy-related side effects [Time frame: up to 10 years]
  • Incidence of chronic side effects related to radiotherapy [Time frame: up to 10 years]
  • Incidence of second cancers [Time frame: up to 10 years]
Secondary outcome measures (4)
  • Patient survival in terms of overall survival (OS, overall survival) and progression-free survival (PFS, progression-free survival) [Time frame: up to 10 years]
  • Adequacy of radiation treatment understood as compliance with the requirements in terms of target coverage [Time frame: up to 10 years]
  • Adequacy of radiation treatment understood as dose conformation to the target [Time frame: up to 10 years]
  • Homogeneity of dose to the target [Time frame: up to 10 years]

Eligibility criteria

Inclusion criteria

  • Pediatric, adolescent, and young adult (<25 years old) patients with malignant neoplasm
  • Adult patients (≥25 years) with malignant neoplasm with histology typical of pediatric age but rarely also found in adults and typically treated wherever possible in pediatric protocols (mainly: Central nervous system malignancies such as medulloblastomas and other embryonal tumors, ependymomas, and germ cell tumors; soft tissue and bone sarcomas such as rhabdomyosarcomas and Ewing's sarcomas; nephroblastomas; neuroblastomas)
  • Underwent radiation treatment at the Pediatric Radiotherapy Unit of the CRO in Aviano
  • Between October 24, 1991, and September 30, 2020, with regard to the retrospective phase of the study, and between October 1, 2020, and September 30, 2030, with regard to the prospective phase of the study
  • And who provide informed consent to the study if alive and traceable at the time of enrollment with regard to the retrospective phase of the study and necessarily with regard to the prospective phase. Regarding deceased or alive but untraceable patients enrollable in the retrospective phase of the study, since these are patients who had already given consent to data processing at the time of the radiation therapy being analyzed and registration/enrollment in any specific treatment/research protocols, no new consent is required for the study
