Study summary

The goal of this type of observational study is to investigate the preliminary effect of 3D printed personalized extendable prosthesis replacement on limb salvage in children with osteosarcoma. The main question it aims to answer is:

Is 3D printed personalized extendable prosthesis replacement has a good outcome in limb salvage pediatric osteosarcoma?

Read the detailed description

Osteosarcoma is one of the most common primary malignant bone tumors in children and adolescents. In this study, the investigators try to investigate the preliminary effect of 3D printed personalized extendable prosthesis replacement on limb salvage in children with osteosarcoma.

Study population

children with osteosarcoma undergoing prosthesis replacement or limb amputation were admitted to our hospital

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • tumors of the extremities, with moderate soft-tissue invasion
  • the neurovascular bundle is not invaded, and the tumor can be excised totally
  • no lesions or metastases can be cured

Exclusion criteria

Exclusion Criteria:

  • recurrent tumors
  • poorly differentiated tumors
  • poor soft-tissue conditions
  • neurovascular invasion around tumors
  • ineffective chemotherapy with
Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Metastases

Cancer that has spread from where it began to other parts of the body. “Metastatic” cancer is cancer that has spread this way.
