[Local recurrence in colon and rectal cancer]

Area of Science:

• Oncology
• Surgical Oncology
• Gastroenterology

Context:

• Colorectal cancer is the second leading cause of cancer death globally.
• Cancer recurrence after surgery significantly contributes to mortality.
• Tumor characteristics and invasion grade are primary drivers of locoregional recurrence.

Purpose:

• To highlight the importance of surgical technique and neoadjuvant therapy in rectal cancer.
• To emphasize the necessity of post-operative surveillance for detecting recurrence.
• To underscore the role of multidisciplinary evaluation in managing metastatic disease.

Summary:

• Effective surgical techniques, including mesorectal excision and achieving adequate margins, are vital in rectal cancer treatment.
• Selective neoadjuvant chemoradiotherapy plays a role in managing rectal cancer.
• Post-operative follow-up is essential for identifying asymptomatic recurrence, with curative surgery possible even in cases of distant metastases.

Impact:

• Improved surgical training can reduce recurrence rates.
• Timely detection of recurrence through surveillance can lead to successful salvage surgery.
• Multidisciplinary assessment is key to optimizing treatment strategies for colorectal cancer patients, including those with metastases.
