Oncolytic viruses: A novel treatment strategy for breast cancer

Area of Science:

• Oncology
• Virology
• Biotechnology

Background:

• Breast cancer remains a leading cause of mortality in women, with conventional therapies often facing resistance and severe side effects.
• The limitations of existing treatments necessitate the exploration of novel therapeutic strategies for breast cancer.

Purpose of the Study:

• To review and summarize the current landscape of viro-therapeutic agents for breast cancer treatment.
• To propose novel combinatorial strategies involving recombinant viruses, transgenes, and drugs for enhanced efficacy.

Main Methods:

• Comprehensive literature review of DNA- and RNA-containing viruses investigated for breast cancer virotherapy.
• Analysis of various virotherapy mechanisms, including direct oncolysis, transgene expression, and immune response induction.
• Exploration of proposed combinatorial treatment strategies using recombinant viruses.

Main Results:

• Several viruses, including adenovirus, herpes virus, vaccinia, reovirus, Newcastle Disease virus, measles virus, and vesicular stomatitis virus, have shown potential in breast cancer virotherapy.
• Recombinant viruses engineered with transgenes and used in combinatorial treatments demonstrate efficacy against human breast cancer.
• Virotherapy offers multiple mechanisms for targeting cancer cells and stimulating anti-tumor immunity.

Conclusions:

• Virotherapy represents a developing and promising frontier in breast cancer treatment, offering an alternative to conventional therapies.
• Combinatorial approaches using engineered viruses hold significant potential for improving treatment outcomes in breast cancer.
• Further research into viro-therapeutic agents and strategies is crucial for advancing breast cancer care.
