Breast Cancer and Anaesthesia: Genetic Influence.

Area of Science:

• Oncology
• Anesthesiology
• Cancer Biology

Background:

• Breast cancer is a heterogeneous disease with significant inter-subject variability.
• Surgical treatment is crucial, but the perioperative period impacts patient survival and recurrence.
• Individualized medicine is increasingly relevant due to tumor heterogeneity and variable biomarkers.

Purpose of the Study:

• To review current evidence on the effects of anesthetic agents and techniques on long-term oncologic outcomes in breast cancer surgery.
• To explore the biomolecular mechanisms linking anesthesia to cancer progression and metastatic spread.
• To highlight the need for prospective randomized clinical trials in cancer and anesthesia research.

Main Methods:

• Systematic review of existing literature on anesthesia, analgesia, and breast cancer outcomes.
• Analysis of studies investigating the pro-tumoral effects of perioperative agents.
• Examination of evidence on anesthetic techniques influencing cancer cell survival and growth.

Main Results:

• Growing evidence suggests anesthetic and analgesic agents may influence cancer recurrence and metastatic progression.
• Anesthetic techniques can affect the physiopathological mechanisms governing residual cancer cell survival post-surgery.
• The interaction between anesthetic agents and tumor biology is complex and requires further elucidation.

Conclusions:

• The perioperative anesthetic management may significantly influence breast cancer patient survival and recurrence.
• Understanding the pro-tumoral effects of anesthetic agents is critical for optimizing cancer care.
• High-quality clinical trials are essential to establish definitive evidence on the relationship between anesthesia and oncologic outcomes.
