Background/Aims: The prematurely closed Stent-In II trial in patients with left-sided obstructive colon cancer may have influenced clinical decision making in The Netherlands. The aim of this study was to evaluate treatment of left-sided malignant colon obstruction at a population level since then. Methods: Short-term outcomes of all patients who underwent resection for left-sided obstructive colon cancer between 2009 and 2012 were assessed based on a prospective national registry. Results: In total, 1,816 evaluable patients were included; acute resection was performed in 1,485 (81.8%), and endoscopic stent or decompressing stoma followed by resection in 196 (10.8%) and 135 (7.4%), respectively. The use of endoscopic stenting significantly decreased from 18% (2009) to 6% (2012). Overall 30-day or in-hospital mortality rate was 6.9, 5.6, and 3.7%, respectively (p = 0.107). Mortality rate after acute resection was 2.9% in patients >70 years, but mortality rates up to 32.2% were observed in high-risk elderly patients. Conclusion: Acute resection as first choice treatment seems justified for patients >70 years of age given a mortality rate of 3%. For the elderly frail patients, mortality rates over 30% after acute resection stress the need for alternative treatment strategies.

This study showed both NLR and PLR to be independently associated with survival in patients who were treated for skeletal metastasis.
