ABSTRACT
The psychological care of adolescent with cancer and their caregiver is a crucial aspect to assure adherence of care and clinical advantages especially for foreign families which leave their country in search of specialized oncological treatment. In these particular familiar conditions, it is even more important to examine the concordance between adolescent patients and caregiver on their experience from an emotional point of view in order to address their needs and to provide personalized support and management.
This case report explores the agreement between a 16 years-old male young patient with multi-treatment metastatic nasopharyngeal carcinoma and his mother about their emotional and behavioral symptoms. The administration of different reliable and valid instruments (i.e., Child Behavior Checklist – CBCL, Youth Self-Report – YSR, Hospital Anxiety and Depression Scale – HADS and Impact of Event Scale-Revised – IES-R) for assessing symptoms evidence a bias between adolescent and caregiver which report more problems than adolescent did. In order to ensure a personalized management for the family as a whole, a complete assessment of the psychological state of patients and caregivers through multiple informants is recommended especially when they are experiencing multiple traumatic experiences.

IMPACT STATEMENT 
The study highlights the importance of structured psychosocial support for adolescent cancer patients and caregivers, emphasizing understanding emotions and behaviors to provide holistic care addressing both physical and psychological needs.
