    Abstract:
    Real-time polymerase chain reaction procedure was used to evaluate bioptic tumor samples from patients suffering cervical carcinoma (CC) stages I-IV. Out of 110 patients, high-risk human papillomavirus (HPV) infection was identified in 98 (89.1%), HPV type 16--63, HPV type 18--10 and HPV type 45--5. One of genotypes 31.33, 35, 39, 52, 58, 59 was established in 8 and a combination of several genotypes of the virus--12 patients. Frequency of remission in CC patients associated with HPV type 16 who had survived 3 years was significantly higher than in the same category associated with HPV type 18 (p=0.03). Relapse frequency and mortality rates in patients with tumors associated with one of viruses 31.33, 35, 39, 52, 58 or 59 were higher as compared with HPV type 16--associated cases 2 years (p=0.03) or 3 years on (p=0.11), respectively. A similar trend was established for squamous-cell tumors stages 1 and 2 (p=0.07) (p=0.12), respectively. No difference was observed in efficacy of therapy for infection with one or a combination of several genotypes of high-risk HPV. Hence, the genotype of virus is believed to be a factor of prognosis in CC early cancers. However, a definitive conclusion cannot be reached until results of a larger body of evidence and longer follow-up are available.
