cTNM – TNM classification; BMI – Body Mass Index, upper limb circumference: 1–10 cm above the lateral epicondyle of humerus, 2–10 cm below the lateral epicondyle of humerus, 3 – mid-metacarpal region without the thumb; numbers in the table correspond to the p value; p-value from paired Student’s t-test
