Oral mucositis in paediatric acute lymphoblastic leukemia patients receiving methotrexate-based chemotherapy: case series

Authors:

ABSTRACT

Aim

Oral mucositis (OM) is a painful and inflammatory ulcerative lesion occurring as an adverse effect during chemotherapy in children with acute lymphoblastic leukemia (ALL). This condition may cause significant systemic anomalies such as malnutrition, opportunistic infections, and delay in the chemotherapy course. This report aims to describe a case series of 11 ALL patients treated with methotrexate as chemotherapy agent. CASE SERIES: Each patient was carefully followed-up and orally examined for 14 days after their chemotherapy session. OM occurred in all children. Then, the Multinational Association of Supportive Care in Cancer and the International Society of Oral Oncology (MASCC/ISOO) management protocol for OM was applied to them. The mean time of the lesion total resolution was 3.7 days.

Conclusion

It is necessary to emphasise the importance of early detection of OM through a close clinical oral examination of children and adolescents with ALL undergoing methotrexate chemotherapy. Pain/infection control and the maintenance of good levels of oral hygiene are fundamental during the management of OM. Therefore, paediatric dentists need to be part of the oncology care team, and thus contributing and helping with ALL treatment.
