Targeted Cancer Therapies

7.5K
The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
There are several types of targeted therapies against...

Cancer Therapies

7.6K
Cancer therapies are various modes of treatment, such as surgery, radiation therapy, and chemotherapy that are administered to cancer patients.
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...

Area of Science:

  • Oncology
  • Biotechnology
  • Medical Engineering

Background:

  • Reversible electroporation (EP) uses electrical pulses to increase cell membrane permeability, enabling targeted drug delivery.
  • Electrochemotherapy (ECT) utilizes EP for delivering chemotherapeutics like cisplatin and bleomycin, and also calcium or gene therapies.
  • ECT is validated for palliative treatment of cutaneous tumors, with demonstrated objective response rates of approximately 80%.

Purpose of the Study:

  • To review the applications and advancements of reversible electroporation (EP) in cancer therapy.
  • To assess the efficacy and safety of electrochemotherapy (ECT) for cutaneous and deep-seated tumors.
  • To identify areas for future research and international collaboration in EP-based cancer treatments.

Main Methods:

  • Review of existing evidence on reversible electroporation (EP) and electrochemotherapy (ECT).
  • Analysis of treatment outcomes, including objective response rates and regression of non-treated lesions.
  • Evaluation of advancements in electrode development for treating deep-seated tumors.
  • Consideration of novel applications like calcium EP and immunogene electrotransfer.

Main Results:

  • ECT demonstrates a mean objective response rate of ~80% for cutaneous tumors.
  • Regression of non-treated lesions suggests a potential in situ vaccination effect.
  • Advancements allow EP treatment of deep-seated tumors with demonstrated in vivo safety.
  • Calcium EP and immunogene electrotransfer are feasible but require further research.

Conclusions:

  • ECT is an effective palliative treatment for cutaneous tumors, with potential for broader applications.
  • Further development in electrode design and modeling is needed for optimal electrical coverage.
  • International collaboration and standardized data collection are crucial for advancing EP therapies and identifying optimal combination treatments.
