Surgery for Colorectal Cancer - Trends, Developments, and Future Perspectives

Area of Science:

• Oncology
• Surgical Oncology
• Gastroenterology

Background:

• Colorectal surgery is a primary treatment for colon cancer, but technical aspects influencing recurrence-free survival remain debated.
• Key areas of debate include complete mesocolic excision (CME), metastatic disease management, hyperthermic intraperitoneal chemotherapy (HIPEC), and recurrent disease treatment.
• Emerging surgical techniques require validation for radical resection efficacy.

Purpose of the Study:

• To review the current literature on critical issues in oncologic colorectal surgery.
• To evaluate the impact of complete mesocolic excision (CME) and lymph node dissection.
• To assess treatment strategies for metastatic and recurrent colorectal cancer, including peritoneal spread.

Main Methods:

• A structured literature review was conducted.
• The review focused on identifying the state-of-the-art regarding key challenges in colorectal surgery.

Main Results:

• The literature highlights the importance of complete mesocolic excision (CME) and lymph node dissection.
• Current strategies for metastatic disease, including peritoneal spread, are reviewed.
• Treatment options for recurrent colorectal cancer are discussed.

Conclusions:

• Complete elimination of malignancy through surgery is fundamental for long-term tumor-free survival.
• Multimodal treatment approaches are essential for achieving optimal oncologic outcomes.
• Surgical techniques and strategies significantly impact recurrence-free survival in colorectal cancer.
