Aim: To evaluate the role of postchemotherapy FDG PET and compare it with other predictive factors in paediatric Hodgkin's disease (HD). Materials and methods: In this retrospective study, 98 paediatric patients with HD (enrolled in eight Italian centres) were analysed. Their mean age was 13.8 years (range 5-19 years). A PET scan was performed at the end of chemotherapy and reported as positive or negative on the basis of visual and/or semiquantitative analysis. True outcome was defined as remission or disease on the basis of combined criteria (clinical, instrumental and/or histological) with a mean follow-up period of 25 months. Statistical analyses were performed for the postchemotherapy PET results and other potential predictive factors (age cut-off, stage, presence of bulky masses and therapeutic group) with respect to patient outcome and progression-free survival (PFS). Results: Overall the patients had a mean PFS of 23.5 months (range 4-46 months): 87 achieved remission (88.8%) and 11 showed disease. Of the 98 patients, 17 were positive on postchemotherapy PET. Seven patients (41%) showed disease during follow-up, and relapse occurred in only four out of the 81 patients who were negative on PET (p=0.0001). Kaplan-Meier analysis demonstrated significant correlations between PFS and the postchemotherapy PET result (p=0.0001) and a cut-off age at diagnosis of 13.3 years (p=0.0337), whereas disease stage (p=0.7404), therapeutic group (p=0.5240) and presence of bulky masses (p=0.2208) were not significantly correlated with PFS. Multivariate analysis confirmed a statistically significant correlation with PFS only for the postchemotherapy PET findings (p=0.0009). Conclusion: In paediatric HD, age at diagnosis and postchemotherapy PET results are the main predictors of patient outcome and PFS, with FDG PET being the only independent predictive factor for PFS. © Springer-Verlag 2011.

Background: A joint analysis of clinical data from centres within the European section of the International Society of Intraoperative Radiation Therapy (ISIORT-Europe) was undertaken in order to define the range of intraoperative radiotherapy (IORT) techniques and indications encompassed by its member institutions. Materials and methods: In 2007, the ISIORT-Europe centres were invited to record demographic, clinical and technical data relating to their IORT procedures in a joint online database. Retrospective data entry was possible. Results: The survey encompassed 21 centres and data from 3754 IORT procedures performed between 1992 and 2011. The average annual number of patients treated per institution was 42, with three centres treating more than 100 patients per year. The most frequent tumour was breast cancer with 2395 cases (63.8 %), followed by rectal cancer (598 cases, 15.9 %), sarcoma (221 cases, 5.9 %), prostate cancer (108 cases, 2.9 %) and pancreatic cancer (80 cases, 2.1 %). Clinical details and IORT technical data from these five tumour types are reported. Conclusion: This is the first report on a large cohort of patients treated with IORT in Europe. It gives a picture of patient selection methods and treatment modalities, with emphasis on the main tumour types that are typically treated by this technique and may benefit from it. © 2013 Springer Heidelberg Berlin.
