Characterization of patients in present study (J-HERS 2021)
The age distribution of the included patients is shown in Table 1. Most patients (74%) visited the clinics for cervical cancer screening, 14% visited for examinations of abnormal cytology results or follow-up regarding a history of CIN, and 12% visited for common obstetrics and gynecologic disorders or follow-up regarding benign diseases. Two hundred and ninety-nine patients (20%) underwent prophylactic HPV vaccination (Table.1). Among them, 54 (19%) received bivalent vaccines, 28 (10%) received quadrivalent vaccines, 5 (1.8%) received nonavalent vaccines, and 191 (69%) did not know the type of vaccine they had received. There was no so much difference in the rate of HPV vaccination according to the reason for the clinic visit (Table 1). Aveilable data showed that 156 subjects (79%) received the HPV vaccine at 12 to 16 years of age.
