Abstract:
Tumor-Treating Fields (TTFields) use intermediate-frequency and low-intensity electric fields to inhibit tumor cells. However, their mechanisms are still not well understood. This article reviews their key antitumor mechanisms at the cellular and molecular levels, including inhibition of proliferation, induction of death, disturbance of migration, and activation of the immune system. The multifaceted biological effects in combination with other cancer treatments are also summarized. The deep insight into their mechanism will help develop more potential antitumor treatments.
Insights
Tumor-Treating Fields (TTFields) use electric fields to fight cancer by stopping tumor cell growth and triggering cell death. Understanding these mechanisms can lead to better cancer therapies.
Area of Science:
- Oncology
- Biophysics
- Cancer Biology
Background:
- Tumor-Treating Fields (TTFields) are an FDA-approved cancer therapy using intermediate-frequency electric fields.
- The precise mechanisms by which TTFields exert their antitumor effects are not fully elucidated.
- Further understanding of TTFields' biological impact is crucial for optimizing their clinical application.
Purpose of the Study:
- To review the key antitumor mechanisms of TTFields at cellular and molecular levels.
- To summarize the combined effects of TTFields with other cancer treatments.
- To provide insights for developing novel antitumor strategies based on TTFields.
Main Methods:
- Literature review of studies investigating TTFields' effects on cancer cells.
- Analysis of cellular and molecular mechanisms, including proliferation, apoptosis, migration, and immunomodulation.
- Synthesis of data on TTFields in combination therapies.
Main Results:
- TTFields inhibit tumor cell proliferation and induce apoptosis.
- TTFields disrupt cancer cell migration and invasion.
- TTFields can modulate the tumor microenvironment and activate the immune system.
Conclusions:
- TTFields possess multifaceted antitumor mechanisms, impacting cell division, death, and movement.
- Combining TTFields with other therapies can enhance treatment efficacy.
- A deeper understanding of TTFields' mechanisms will facilitate the development of more effective cancer treatments.

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...

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...
