Merath K, et al. - In order to characterize the presentation and oncologic outcomes of intrahepatic cholangiocarcinoma (ICC) patients undergoing curative-intent resection according to category of body mass index (BMI), researchers assessed 790 patients who underwent resection of ICC as normal weight (BMI 18.5–24.9 kg/m²), overweight (BMI 25.0–29.9 kg/m²) and obese (BMI≥30 kg/m²) according to the World Health Organization definition. Out of 790 patients undergoing curative-intent resection of ICC in the analytic cohort, 50.5% had normal weight, 34.7% were overweight, and 14.8% were obese. Observations revealed an association of increasing BMI with incremental increases in the risk of recurrence following curative-intent resection of ICC. Increased BMI was an independent risk factor for tumor recurrence, on multivariable analysis.
