Combination chemotherapy for bone tumors in young adults

Neoadjuvant Three-component Chemotherapy Based on a Combination of Doxorubicin, Cisplatin and Methotrexate in Patients Aged 24-40 Years With Primary Bone Tumors to Increase the Response Rate Compared With Two-component Chemotherapy

Phase2; Phase3 Interventional Blokhin's Russian Cancer Research Center · NCT05057130

This study is testing a new combination of chemotherapy drugs for young adults with bone tumors to see if it helps shrink the tumors and improve their chances of recovery.

What this trial studies

This clinical trial investigates the effectiveness of a neoadjuvant chemotherapy regimen combining Doxorubicin, Cisplatin, and Methotrexate in patients aged 24 to 40 years with primary bone tumors, specifically osteosarcoma. Participants will receive two cycles of this three-component chemotherapy, with careful monitoring of drug administration and potential side effects. The study aims to improve tumor response rates and reduce the likelihood of recurrence by optimizing the use of Methotrexate, which has shown promise in previous studies despite concerns regarding its safety in older patients. The trial will assess the impact of this regimen on treatment outcomes and overall disease prognosis.

Who should consider this trial

Good fit: Ideal candidates are adults aged 24 to 40 with a histologically confirmed diagnosis of operable primary bone tumors.

Not a fit: Patients with inoperable tumors or those with specific types of sarcomas other than osteosarcoma may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could significantly improve the prognosis and response rates for young adults with primary bone tumors.

How similar studies have performed: Previous studies have shown promising results with similar chemotherapy regimens, indicating potential for success in this approach.
