Evaluation of ABO/Rh blood group distributions in papillary thyroid cancer patients

The study aimed to evaluate the ABO/Rh blood group distributions and their relationship with clinical-pathological features in papillary thyroid cancer patients. It was planned as a retrospective case-controlled study. The blood group distributions of the patients were contrasted with that of the general population. Additionally, the association between clinical-pathological variables and blood group distribution was assessed. Two hundred and ninety-three patients were involved in the study. The median age was 48 years, and the majority of patients were female (84.3%). The most common variants of papillary thyroid cancer were follicular, classical, and oncocytic. The majority of the patients had stage 1 (91.1%) disease at the time of diagnosis. ABO blood group distributions in the patient (47.4% A, 11.9% B, 8.2% AB, 32.4% O) and control (42% A, 16% B, 8% AB, 34% O) groups were found to be similar ( P = .8). In terms of Rh factor, there was a comparable distribution for the characteristics of the patient and healthy control group ( P = .6). There was no association between clinical and pathological variables and blood group distributions (gender, age, tumor stage, tumor location, and pathological tumor variant). Comparing patients with papillary thyroid carcinoma to the healthy control group, the prevalence of the A blood group numerically increased while the prevalence of the B blood group numerically decreased, but it was not statistically significant. In addition, ABO/Rh blood type and clinical and pathological variables did not relate.
