OBJECTIVE: To evaluate several metabolic changes in patients with differentiated thyroid carcinoma (DTC ) which enhance cardiovascular risk in the western region of Nepal. MATERIALS AND METHODS: This hospital based case control study was carried out using data retrieved from the register maintained in the Department of Biochemistry of the Manipal Teaching Hospital, Pokhara, Nepal between 1st January, 2009 and 31st December, 2011. The variables collected were age, gender, BMI, glucose, insulin, HbA1C, CRP, fibrinogen, total cholesterol, triglycerides, HDL, LDL, VLDL, f-T3, f-T4, TSH. One way ANOVA was used to examine statistical significance of differences between groups, along with the Post Hoc test LSD for comparison of means. RESULTS: fT3 values were markedly raised in DTC cases (5.7±SD1.4) when compared to controls (2.2±SD0.9). Similarly, fT4 values were also moderately raised in cases of DTC (4.9±SD1.3 and 1.7 ±SD0.9). In contrast, TSH values were lowered in DTC cases (0.39±SD0.4) when compared to controls (4.2 ±SD 1.4). Mean blood glucose levels were decreased while insulin was increased and HDL reduced (39.5±SD4.7 as compared to the control 43.1±SD2.2). CONCLUSION: Cardiovascular risk may be aggravated by insulin resistance, a hypercoagulable state, and an atherogenic lipid profile in patients with differentiated thyroid cancer.
