Clinical–Pathologic Characteristics and Long-term Outcomes of Left Flexure Colonic Cancer: A Retrospective Analysis of an International Multicenter Cohort

BACKGROUND: Colorectal cancer seldom presents at the splenic flexure. Small series on left flexure tumors reported a high occurrence of negative prognostic factors called into question as causes of poor prognosis. However, because of the small number of cases, no definite conclusions can be drawn. OBJECTIVE: The aim of this study was to compare clinical-pathologic characteristics and short- and long-term outcomes of left flexure tumors with other colonic locations. DESIGN: This was a retrospective analysis of consecutive patients who underwent surgery for tumors at the splenic flexure. Each tumor was paired in a 1 to 1 fashion with a right-sided and sigmoid tumor. SETTINGS: The study was conducted in 10 international centers. PATIENTS: A total of 641 patients with left flexure tumors were included in the study. MAIN OUTCOME MEASURES: Overall survival and cancer-specific survival were measured. RESULTS: Left flexure tumors presented more frequently with stenosis (30.5%; p
