In the world of pediatric oncology, the use of cannabinoids for children with cancer is a topic of increasing interest. While cannabis-based products have gained popularity for symptom management, a recent systematic review suggests that there is still a lack of evidence regarding the dosing, safety, and efficacy of cannabinoids in pediatric cancer patients. Only a small number of randomized controlled trials reported on efficacy outcomes, and the heterogeneity among these trials made it difficult to pool the data. Furthermore, while cannabinoids were reported to be superior to active control groups for controlling nausea and vomiting, there is a significant knowledge gap when it comes to their impact on pain, mood, sleep, anxiety, and overall quality of life. Safety concerns were also raised, as patients using cannabinoids had higher risks of developing certain adverse effects. In conclusion, there is an urgent need for further research to explore the benefits and harms of cannabis in this vulnerable population, as well as the development of standardized guidelines for reporting cannabis-related adverse events.

Products studied
The researchers examined various cannabis-based products in their analysis. These included medical-grade cannabinoids, synthetic cannabinoids, and unspecified cannabis herbal extracts. By studying different types of products, the researchers were able to evaluate the overall landscape of cannabinoid use in children with cancer.
Efficacy of Cannabinoids
Indications for cannabinoid use in children with cancer
The most common indication for the use of cannabinoids in children with cancer was the management of nausea and vomiting. Among the included studies, 11 out of 19 focused on controlling these symptoms. However, there is still a knowledge gap regarding the impact of cannabinoids on other symptoms, such as pain, mood, sleep, anxiety, and health-related quality of life.
Superiority of cannabinoids compared to active control groups
Overall, the use of cannabinoids was reported to be superior to active control groups in the included studies. However, due to the limited number of randomized trials and the heterogeneity among the studies, it was not possible to pool efficacy data. This highlights the need for more research to establish a clearer understanding of the effectiveness of cannabinoids in children with cancer.
Knowledge gap regarding impact on pain, mood, sleep, anxiety, and quality of life
While the efficacy of cannabinoids in managing nausea and vomiting has been studied to some extent, there is still a lack of evidence regarding their impact on other symptoms commonly experienced by children with cancer. More research is needed to determine the effectiveness of cannabinoids in managing pain, improving mood, promoting better sleep, reducing anxiety, and enhancing overall quality of life in this population.
Safety of Cannabinoids
Higher risks of somnolence, high, dizziness, dry mouth, and increased appetite
The use of cannabinoids in children with cancer comes with certain risks. In the interventional studies included in the analysis, patients who used cannabinoids had a higher risk of experiencing somnolence, feeling high, dizziness, dry mouth, and increased appetite compared to control groups.
Adverse events reported in observational studies
Observational studies reported several cannabinoid-related adverse events (AEs). These adverse events included drowsiness, dizziness, headache, and euphoria. It is important to monitor and address these potential side effects when considering the use of cannabinoids in children with cancer.
Withdrawals due to adverse events
In two studies, participants receiving cannabinoids were more likely to withdraw from the study due to adverse events compared to those in the comparator groups. This suggests the need for caution and close monitoring when using cannabinoids in this population.
Lack of serious cannabis-related adverse events
Despite the potential risks associated with cannabinoid use in children with cancer, no serious cannabis-related adverse events were reported across all the included studies. This is an encouraging finding that supports the overall safety of cannabinoids in this population, although further research is needed to fully understand their long-term effects.
Need for Interventional Studies
Comparison of safety and efficacy of cannabinoids with available treatment options
To assess the true safety and efficacy of cannabinoids in children with cancer, it is important to compare them to the available treatment options. Interventional studies that directly compare cannabinoids with existing therapies can provide valuable insights into the potential benefits and risks of cannabinoid use.
