Abstract:
Although osteosarcoma (OS) is a rare malignancy, it is ranked among the leading causes of cancer-related death in the pediatric age group. The cancer's low prevalence and its large tumor heterogeneity make it difficult to obtain meaningful progress in patient survival. In this review we present an overview of current clinical trials which largely focus on stimulation of the immune system or rely on the inhibition of kinases such as Src and mTOR. The potential efficacy of tumor-targeted TNFalpha is discussed, as well as the importance of preclinical validation of new targets. To improve the success of future clinical trials, clinicians and basic researchers need to intensify their exchange. Finally, a case is made for individualized treatment of OS patients, based on interdisciplinary cooperation in dedicated Sarcoma Centers.
Insights
Osteosarcoma (OS) is a rare pediatric cancer with poor survival rates. This review highlights current clinical trials and emphasizes the need for better preclinical validation and individualized treatment strategies for osteosarcoma.
Area of Science:
- Oncology
- Pediatric Oncology
- Cancer Research
Background:
- Osteosarcoma (OS) is a rare but aggressive bone cancer, a leading cause of cancer death in children and adolescents.
- Tumor heterogeneity and low prevalence present significant challenges in developing effective treatments and improving patient survival rates.
- Current therapeutic strategies often involve immune system stimulation or kinase inhibition (e.g., Src, mTOR).
Purpose of the Study:
- To review current clinical trials for osteosarcoma.
- To discuss novel therapeutic targets and the importance of preclinical validation.
- To advocate for enhanced collaboration and individualized treatment approaches for osteosarcoma patients.
Main Methods:
- Review of existing clinical trials for osteosarcoma.
- Discussion of targeted therapies, including tumor-targeted TNFalpha.
- Emphasis on preclinical validation and interdisciplinary cooperation.
Main Results:
- Current trials focus on immunotherapy and kinase inhibitors (Src, mTOR).
- Tumor-targeted TNFalpha shows potential efficacy.
- Preclinical validation is crucial for advancing new therapeutic targets.
Conclusions:
- Improved osteosarcoma patient survival requires intensified exchange between clinicians and basic researchers.
- Individualized treatment strategies, facilitated by interdisciplinary cooperation in Sarcoma Centers, are essential for future success.
- Further research into novel targets and robust preclinical validation is critical for advancing osteosarcoma therapy.

Cancer Therapies
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
Tumor Progression
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
