Hypothesis

Cisplatin may have additive activity with temozolomide due to ablation of the DNA repair protein O6-alkylguanine-DNA alkyltransferase (MGMT).

Conclusion

The combination of cisplatin and temozolomide is well tolerated in children and adolescents, generating no toxicity greater than that of the single agents.

Supporting Evidence

  • 39 patients with refractory or recurrent solid tumors were treated.
  • Partial responses were observed in several patients with malignant gliomas and neuroblastomas.
  • Low MGMT activity correlated with increased severity of thrombocytopenia.

Takeaway

Doctors tested a new medicine combination to help kids with tough cancers, and it worked without making them sicker than usual.

Methodology

This phase I/II study used the Continual Reassessment Method to determine safe doses and evaluate toxicity and antitumor activity in pediatric patients.

Potential Biases

Potential bias due to the study design and patient selection criteria.

Limitations

The study included a small sample size and was limited to specific patient cohorts.

Participant Demographics

Median age was approximately 13 years; included 25 males and 14 females.
