A 55-year-old patient with stage IV rectal cancer (synchronous liver metastases, 3 bilobar, technically resectable) is evaluated for treatment strategy. Which management approach is supported by current ESMO guidelines for potentially resectable synchronous colorectal liver metastases?
- A Rectal surgery first, then systemic chemotherapy, then liver resection
- B Liver-first strategy with hepatectomy before rectal resection after downsizing chemotherapy ✓
- C Simultaneous resection of rectum and liver in a single operation
- D Systemic chemotherapy alone without surgical consideration
Explanation
For synchronous potentially resectable colorectal liver metastases (CRLM) from rectal primary, ESMO and NCCN guidelines support a liver-first approach (reverse strategy) when the rectal primary is not obstructing or threatening perforation. This strategy addresses the metastatic disease first (the principal determinant of survival), avoids delaying liver resection while the primary rectal cancer is managed, and allows assessment of chemotherapy response before committing to major hepatectomy. Simultaneous rectal and liver resection is associated with high morbidity. A rectal-first approach risks delaying liver resection in patients with progressive metastases.
