Study of the role of various diagnostic methods in patients with benign and neoplastic cervical diseases

Abstract

Introduction . Cervical intraepithelial neoplasias that have been recognized as a precursor of squamous cell carcinoma are subject to active detection for the purpose of eradication. Human papillomavirus (HPV) exposure of women is the major risk factor for carcinogenesis, which is a necessary part for the formation of a pre-tumour and malignant phenotype. Cervical intraepithelial neoplasias that precede the development of squamous cell carcinoma should be actively detected and treated early. The identification of patients with HPV is an important part of subsequent therapies. Inosine pranobex is used as one of the components of the treatment of HPV-associated diseases. Aim . To study the role of various diagnostic methods in patients with benign and neoplastic cervical processes. Materials and methods . The study included 311 women who were 21–64 years old. Colposcopy, cytological examination, HPV testing, preliminary biopsy, cervical excise with histological evaluation of tissue sampling were carried out. Results . HPV 16 was more often detected in a malignant tumour and CIN 3; HPV type 31 and 33 were more often detected in CIN 2 and CIN 3; HPV type 18 was detected in almost all patient with CIN, and malignant and benign neoplastic disorders in preliminary biopsy, that was not typical of results of the excision. In excision CIN 1 were confirmed in 17.07%, CIN 2 in 31.88%, CIN 3 in 66.67%. Preliminary results of benign process in 6.67% turned out to be CIN 1, and in 6.67% – CIN 2, that confirms the need for a comprehensive evaluation. Studies of prevalence of various types of HPV showed that the established sequence of recommended tests, which consists of extended colposcopy, cytology and identification of HPV types, if necessary, does not always correspond to the biopsy results and histological findings on cervical excision specimens. According to our sources, the final result can be determined after excision procedure of cervical tissue and histological examination of the tissue obtained. Conclusion . No strong correlations between examination methods and cervical pathology have been revealed. The final diagnosis is made after cervical biopsy. High prevalence of different types of HPV raises the question of need for complex therapy with inclusion the inosine pranobex.
