Abstract
INTRODUCTION: Human papillomavirus (HPV) is the leading cause of cervical cancer and early detection is crucial for effective prevention. The standard HPV detection method, cervical smear PCR, entails discomfort and deters many women. Therefore, it is challenging to screen large populations for HPV from cervical smear samples. In this study, we investigated the sensitivity of detecting HPV by PCR in concentrated urine samples. METHODS: Urine and cervical smear samples were collected from 126 patients (ages 20–35) at Acibadem Altunizade Hospital. Urine samples were concentrated by a tool (MyMagiCon). The presence of HPV DNA in cervical smear and urine samples was determined by PCR. RESULTS: Among 126 patients, HPV was detected in 57 either in at least one of the sample types (cervical smear, urine, and concentrated urine). Among all HPV-positive patients, HPV was identified in 87.7% of swab samples, 86% of concentrated urine samples, and only 73.7% of unconcentrated urine samples. The χ2 test comparing cervical smear and concentrated urine samples yielded a Kappa value of 0.78 (95% confidence), indicating strong statistical correlation within this study. Additionally, PCR from concentrated urine samples, identified six HPV-positive samples that were HPV negative in cervical smear samples of the same patients. CONCLUSION: It was possible to identify HPV in concentrated urine samples by PCR with a sensitivity almost equal to cervical smear sampling. Since obtaining urine is much easier than obtaining cervical smear samples, this may enable easy screening of large populations for HPV. This may have a big effect in the prevention of cervical cancer.
