Tumor cell motility as a novel target in cancer--experimental and clinical results
1Klinik für Urologie, Med. Einrichtungen der Universität Essen, Essen, Germany.
Background:
Surgery, chemotherapy and radiotherapy are the mainstay of tumor management. However, in systemic disease cure can be achieved in yet a few tumor entities. Based on cell biological research we have characterized the process of tumor progression and metastasis and disclosed that the loss of cell-cell adhesion in association with an increased tumor cell motility is an essential feature of the malignant potential of a tumor.
Methods:
According to this principle we derived therapeutical methods differing from hitherto existing treatments by being exclusively focused on tumor cell motility. Characterization of so-called anti-motility factors was performed biochemically as well as with motility assays by in vitro studies in established bladder carcinoma cell lines.
Results:
We evaluated the potential therapeutic benefit in a model of chemically induced bladder carcinoma followed by a phase I/II trial applying antimotility factors in patients with advanced bladder cancer.
Conclusion:
Both basic research as well as the results of first clinical trials confirm, that advanced carcinomas can be influenced by inhibition of tumor cell motility.
Insights
Targeting tumor cell motility offers a novel approach to cancer treatment. This strategy, focusing on inhibiting cancer cell movement, shows promise in advanced carcinomas.
Area of Science:
- Oncology
- Cell Biology
- Cancer Research
Background:
- Standard cancer treatments like surgery, chemotherapy, and radiotherapy are insufficient for systemic disease.
- Tumor progression and metastasis are characterized by loss of cell-cell adhesion and increased tumor cell motility.
- Tumor cell motility is a key feature of malignant potential.
Purpose of the Study:
- To develop novel therapeutic methods targeting tumor cell motility.
- To characterize anti-motility factors for cancer treatment.
Main Methods:
- Biochemical characterization and in vitro motility assays were used to identify anti-motility factors.
- Studies utilized established bladder carcinoma cell lines.
- Therapeutic approaches focused exclusively on inhibiting tumor cell motility.
Main Results:
- The therapeutic benefit of anti-motility factors was evaluated in a chemically induced bladder carcinoma model.
- A phase I/II clinical trial was conducted in patients with advanced bladder cancer.
- Results demonstrated the potential of anti-motility factors in treating advanced bladder cancer.
Conclusions:
- Basic research and early clinical trials confirm that advanced carcinomas can be influenced by inhibiting tumor cell motility.
- Targeting tumor cell motility represents a promising therapeutic strategy for advanced cancers.
