[Retinoids: use in combating cancer]

Area of Science:

• Biochemistry and Molecular Biology: Focuses on retinoids, vitamin A analogues, and their mechanism of action via nuclear receptors.
• Oncology: Investigates the role of retinoids in cancer prevention and therapy across various malignancies.

Context:

• Retinoids modulate cell growth and differentiation, exhibiting anti-cancer properties in preclinical models.
• Clinical use of retinoids is established for certain human cancers, including promyelocytic leukemia, often in combination therapy.

Purpose:

• To explore the efficacy of retinoids in preventing and treating human malignancies.
• To evaluate the role of retinoids in managing mammary carcinoma through ongoing clinical trials.
• To highlight the importance of assessing estrogen or retinyl receptor status prior to retinoid treatment.

Summary:

• Retinoids, vitamin A derivatives, regulate gene transcription through nuclear receptors, impacting cell growth and differentiation.
• They demonstrate efficacy in inhibiting chemically induced carcinogenesis and treating certain human cancers, though challenges like resistance exist.
• Current research includes clinical trials for mammary carcinoma, emphasizing the need to identify receptor presence in tumor tissues for personalized treatment.

Impact:

• Establishes retinoids as significant agents in cancer therapy and prevention.
• Identifies key factors for optimizing retinoid treatment efficacy, such as receptor status.
• Provides a basis for further research into retinoid-based cancer treatments and overcoming therapeutic resistance.
