Abstract
In Morocco, through the finding of the Casablanca population-based registry, all cancers are estimated at 35000 new cases par year and 3.2% are aged less or equal 20 years [1]. In our centre, we treated patient from Casablanca region and the half south of Morocco and we treated children and adults in the same unit. During ten years (2004–2014), we’ve irradiated 5510 children that represented 4% of all patients. The most frequent tumour were the CNS tumours (20.7%) followed by lymphoma (20.7%) specially Hodgkin disease in 75% of all lymphoma. The bone sarcoma was noted in 17.9% and the carcinoma and the epithelial tumours were 16%. We needed anaesthesia for the simulation and the treatment (for all the sessions) in 1% of all cases. We started using conformational radiation therapy since 2008. The locally stages were noted in 75% correlated with the delay of diagnosis. All children were treated by the 2 linear accelerators during all the day especially during the morning. The median time to start radiation was more than 1 month in 68% and 12% more than 3 months. We used the SIOP recommendations and all cases were discussed during the multidisciplinary paediatric oncology committee of the hospital. More time was necessary for the treatment planification since the CT simulation, dosimetry and given radiation.
Highlights
Pediatric cancers represent less than 1% of all cancer
The absolute number of irradiated children is estimated to be quite low and recently new techniques like intensity modulated radiation therapy, protontherapy are used in pediatric oncology and can reduce the late effects
All children received radiation therapy included in multimodal treatment
Summary
Pediatric cancers represent less than 1% of all cancer. Children’ type cancers are very different than for adults. The most common cancers are, breast, prostate, and lung [2]. Radiotherapy is a part of multimodal therapy concepts in pediatric oncology. Significant increase in survival in pediatric oncology was reported in the last 25 years, and the Conventional RT is frequently associated with severe side effects like Growth and musculoskeletal, endocrine and fertility disorders, neuropsychological and secondary cancers [3]. The absolute number of irradiated children is estimated to be quite low and recently new techniques like intensity modulated radiation therapy, protontherapy are used in pediatric oncology and can reduce the late effects
