Human papillomavirus 18 as a poor prognostic factor in stage I-IIA cervical cancer following primary surgical treatment. Obstet Gynecol Sci 2014; 57:492-500. [PMID: 25469338 PMCID: PMC4245343 DOI: 10.5468/ogs.2014.57.6.492] [Citation(s) in RCA: 14] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/27/2014] [Revised: 06/24/2014] [Accepted: 07/15/2014] [Indexed: 11/08/2022] Open
Abstract
OBJECTIVE This study evaluates the effect of the specific human papillomavirus (HPV) genotype as a prognostic factor in stage I-IIA cervical cancer patients following primary surgical treatment. METHODS The medical records of 116 cervical cancer patients treated with primary surgical treatment were reviewed. The HPV genotypes were categorized into following groups: negative and unclassified, HPV 16, HPV 18, and other high risk (HPV 31, 33, 35, 45, 51, 52, 56, and 58). RESULTS Among the HPV genotypes, HPV 16 predominated (40.52%), followed by intermediate risk and unclassified (25%), HPV 18, 45, and 56 (17.24%) and negative (17.24%). In univariate analysis, HPV genotypes (P=0.03), parametrial spread (P=0.02), depth of invasion (DOI) (P<0.01) and lymph-vascular space invasion (P=0.02) were significantly associated with progression free survival (PFS). In multivariate analysis, HPV 18 (hazard ratio [HR], 5.2; 95% confidence interval [CI], 1.29 to 20.90; P=0.02) and ≥one half of DOI (HR, 5.4; 95% CI, 1.08 to 27.31; P=0.04) were significantly associated with PFS. HPV genotypes are not significantly associated with overall survival. CONCLUSION HPV 18 was a poor prognostic factor for the PFS in stage I-IIA cervical cancer patients following primary surgical treatment. Careful long-term observation and regular exams are recommended for cervical cancer patients with HPV 18 compared to those with other HPV genotypes.

HPV-18 is a poor prognostic factor, unlike the HPV viral load, in patients with stage IB-IIA cervical cancer undergoing radical hysterectomy. Gynecol Oncol 2011; 121:546-50. [PMID: 21334052 DOI: 10.1016/j.ygyno.2011.01.015] [Citation(s) in RCA: 25] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/08/2010] [Revised: 12/16/2010] [Accepted: 01/12/2011] [Indexed: 11/24/2022]
Abstract
OBJECTIVES This study was conducted to determine the prognostic significance of the human papillomavirus (HPV) genotype using the HPV DNA chip (HDC) test and the HPV viral load by the hybrid capture II assay (HC2) in FIGO stage IB-IIA cervical cancer undergoing radical hysterectomy. METHODS Between January 2001 and December 2005, 204 consecutive patients who underwent radical hysterectomy with pelvic lymphadenectomy for International Federation of Gynecology and Obstetrics (FIGO) stage IB1-IIA cervical cancer were retrospectively reviewed. The Cox proportional hazard models adjusted for covariates were used for analyses and a receiver operating characteristic (ROC) curve was used to determine the HPV viral load in predicting disease progression. RESULTS Of the 204 cases, the HDC was positive in 195 (95.6%) and the HC2 was positive in 192 (94.1%). The 5-year progression-free survival (PFS) was 78.4%. On multivariate analysis, HPV-18 positivity was an independent prognostic factor predictive for disease progression. The risk of recurrence was higher for HPV-18 positivity (hazard ratio=2.664; 95% confidence interval [CI], 1.437-4.938; P=0.003). The 5-year PFS rate for patients who were HPV-18-negative was 83.8%, which was higher than the 5-year PFS for patients who were HPV-18-positive (54.1%; P<0.001). The area under the ROC curve for the HPV viral load was 0.550 (P=0.314; 95% CI, 0.455-0.644). CONCLUSIONS The HPV-18 genotype is a reliable prognostic factor of early-stage cervical cancer; however, the HPV viral load may not be helpful in predicting disease prognosis.

Clinical effect of human papillomavirus genotypes in patients with cervical cancer undergoing primary radiotherapy. Int J Radiat Oncol Biol Phys 2010; 78:1111-20. [PMID: 20231068 DOI: 10.1016/j.ijrobp.2009.09.021] [Citation(s) in RCA: 40] [Impact Index Per Article: 2.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/10/2009] [Revised: 09/04/2009] [Accepted: 09/04/2009] [Indexed: 11/24/2022]
Abstract
PURPOSE To study the prognostic value of the human papillomavirus (HPV) genotypes in cervical cancer patients undergoing radiotherapy. PATIENTS AND METHODS A total of 1,010 patients with cervical cancer after radiotherapy between 1993 and 2000 were eligible for this study. The HPV genotypes were determined by a genechip, which detects 38 types of HPV. The patient characteristics and treatment outcomes were analyzed using the Cox regression hazard model and classification and regression tree decision tree method. RESULTS A total of 25 genotypes of HPV were detected in 992 specimens (98.2%). The leading 8 types were HPV16, 58, 18, 33, 52, 39, 31, and 45. These types belong to two high-risk HPV species: alpha-7 (HPV18, 39, 45) and alpha-9 (HPV16, 31, 33, 52, 58). Three HPV-based risk groups, which were independent of established prognostic factors, such as International Federation of Gynecology and Obstetrics stage, age, pathologic features, squamous cell carcinoma antigen, and lymph node metastasis, were associated with the survival outcomes. The high-risk group consisted of the patients without HPV infection or the ones infected with the alpha-7 species only. Patients co-infected with the alpha-7 and alpha-9 species belonged to the medium-risk group, and the others were included in the low-risk group. CONCLUSION The results of the present study have confirmed the prognostic value of HPV genotypes in cervical cancer treated with radiotherapy. The different effect of the alpha-7 and alpha-9 species on the radiation response deserves additional exploration.

Abstract
Human papillomavirus (HPV) infections are generally long lasting, and a host immune response to infection is hard to detect. Nevertheless immunocompromised subjects control HPV infection less well than those with intact immunity. Immune responses are best documented for the papillomavirus groups that cause evident human disease, particularly those responsible for anogenital cancers and genital warts. Humoral immunity to the viral capsid has been shown sufficient for protection against infection, while innate and adaptive cell mediated immunity appears important for eventual elimination of HPV infection. However, molecular and cellular mechanisms responsible for protection from and clearance of HPV infection are not completely established.

Abstract
OBJECTIVE The aim of this study is to use a novel ELISA, based on five recombinant HPV-16 and HPV-18 proteins, for detection HPV-specific antibodies in a case-control study. PATIENTS AND METHODS L1, E6 and E7 genes have been over expressed in Escherichia coli as double fused proteins. These recombinant proteins were used in a GST-capture ELISA as coating antigens. Human sera were collected from women with cervical cancer. Negative human sera were collected from patients apparently healthy and may be affected by other infectious agents. RESULTS Most of the sera showed a positive reactivity to at least one of the HPV-16 or HPV-18 proteins (52/71). A percentage of 39.50% of the sera from HPV-16 infected women and 21.12% of the sera from women infected by HPV-18 genotype recognised at least one of the HPV-16 or HPV-18 proteins. Sera showed different reactivity to L1, E6 and E7 antigens, and only a few serum samples reacted to L1, E6 and E7 HPV-16, E6 and E7 HPV-18 (co-infection). Differences of reactivity between cases and controls were significant (P<0.0001). CONCLUSION This novel ELISA, based on recombinant HPV-16 and HPV-18 antigens, is able to detect antibodies in women infected by HPV genotypes. The assay is easy to perform and has low cost, making it suitable for monitoring the natural history of HPV infections as well as for detecting pre-existing HPV antibodies in women who receive vaccination.

Abstract
PURPOSE Our aim was to evaluate the prognostic significance of human papillomavirus (HPV) genotype in early-stage cervical carcinoma primarily treated with surgery in a large tertiary referral medical center. PATIENTS AND METHODS Consecutive patients who underwent primary surgery for invasive cervical carcinoma of International Federation of Gynecology and Obstetrics (FIGO) stage I to IIA between 1993 and 2000 were retrospectively reviewed. Polymerase chain reaction (PCR) using a general primer set followed by reverse-blot detection of 38 types of HPV DNA in a single reaction was performed for genotyping. E6 type-specific PCR was performed to validate multiple types. RESULTS A total of 1,067 eligible patients were analyzed. HPV DNA sequences were detected in 95.1% of the specimens, among which 9.6% contained multiple types. HPV 16 was detected in 63.8% of the samples, and HPV 18 was detected in 16.5% of the samples. The median follow-up time of surviving patients was 77 months. By multivariate analysis, FIGO stage, lymph node metastasis, depth of cervical stromal invasion, grade of differentiation, and HPV 18 positivity were significantly related to cancer relapse. FIGO stage II, deep stromal invasion, parametrial extension, HPV 18 positivity, and age older than 45 years were significant predictors for death. Using the seven selected variables from either recurrence-free or overall survival analysis, death-predicting (P < .0001) and relapse-predicting (P < .0001) models classifying three risk groups (low, intermediate, and high risk) were constructed and endorsed by internal validation. CONCLUSION The independent prognostic value of HPV genotype is confirmed in this study. The prognostic models could be useful in counseling patients and stratifying patients in future clinical trials.

Abstract
OBJECTIVE To evaluate if pretreatment HPV titers in cancer cervix could predict radiation response and survival outcomes. METHODS Twenty-one patients of cancer cervix were treated by radiotherapy (RT) alone. HPV titers were estimated using DNA Hybrid Capture II test. Loco-regional response at 1 month of RT--complete or partial response (CR and PR respectively) and survival outcomes--local disease-free (LDFS), disease-free (DFS) and overall (OS) survivals were evaluated against pre- and posttreatment HPV titers. RESULTS Pretreatment HPV titers ranged from 0.81 to 3966.10 RLU/cut off (mean +/- SD: 1264.39 +/- 1148.22, median: 1129.98). Of the demographic features evaluated, mean HPV titers were significantly different only for patients achieving CR or PR at completion of RT (mean +/- SD for CR vs. PR: 1616.31 +/- 1146.86 vs. 384.57 +/- 538.80, P = 0.022). HPV titers at end of RT ranged from 0.12 to 487.42 RLU/cut off (mean +/- SD: 37.31 +/- 108.60, median: 2.33). Patients with higher pretreatment HPV titers (>1000 RLU/cutoff) had a higher CR (P = 0.022) and better survival compared to those with < or =1000 RLU/cutoff (LDFS, P = 0.004; DFS, P = 0.005; OS, P = 0.012). At completion of RT, those having > or =99.5% fall in HPV had superior survival outcomes than those with <99.5% reduction (LDFS, P = 0.002; DFS, P = 0.002; OS, P = 0.004). CONCLUSIONS Higher pretreatment HPV titers (>1000 RLU/cutoff) could be considered as a predictor of radiotherapy response and survival in cancer cervix. A reduction in these titers to 99.5% of their baseline values at end of radiotherapy is also associated with better survival outcomes.

Abstract
OBJECTIVE Molecular and environmental co-factors are known risk factors for cervical cancer. The aim of this study was to define the prognostic significance of HPV 18 and its phylogenetically related viruses and smoking on survival in patients with early stage cervical cancer. METHODS HPV typing was performed on stage IB-IIB cervical tumors. Subjects positive for HPV 18 or 45 were compared to the remainder of the cohort and to women with tumors containing HPV 16, 31, or 52. Tobacco use was ascertained by patient questionnaire. RESULTS Tumors of 255 women were evaluated. The presence of HPV 18 or 45 was associated with decreased survival. In a multivariable Cox proportional hazards analysis comparing patients with HPV 18 or 45 containing tumors to the rest of the cohort, the hazard ratio for death from cervical cancer was 2.08 (95% CI, 1.07-4.04). The hazard ratio for death from cervical cancer was 2.41 (95% CI, 1.17-4.96) when the HPV 18 and 45 group was compared to women with HPV 16 or its related viruses, 31 and 52. Smoking was associated with a decreased survival for women with HPV 18 or 45, even after adjusting for other known prognostic factors (P = 0.031). CONCLUSIONS In addition to pathologic indicators, molecular and environmental co-factors are important determinates of outcome in early stage cervical cancer. The presence of HPV 18 or 45 is associated with a decreased survival. The adverse effect of HPV 18 and 45 on survival is compounded by tobacco use.

Abstract
OBJECTIVES The principal aim of the study was to verify whether HPV infection in healthy women, as determined by HPV DNA detection, was associated with an increased risk of development of cervical lesions. METHODS Cervical smears collected at enrolment into the prospective study conducted in Prague during 1975-83 were tested for the presence of HPV DNA by means of a polymerase chain reaction (PCR) using the general GP5/6 primers and a mixture of primers specific for the E6 gene. 120 smears from patients in whom cervical neoplasia had been detected in the course of the prospective study and 208 smears from control women who had remained healthy throughout the observation period were analysed. Patients and controls were matched by age, number of sexual partners, age at first intercourse, and smoking habit. Patients were divided into three groups, A, B, and C, according to their cytological, colposcopic, and histological findings at enrolment. Group A consisted of 67 women found ill at enrolment, group B of 26 women with slightly suspicious findings, while group C comprised 27 women with normal findings at enrolment. In addition, sera taken at enrolment from these patients and controls were tested for the presence of antibodies reactive with virus-like particles (VLPs) of HPV 16, 18, and 33. RESULTS For the whole cohort, there was a statistically highly significant difference in the presence of HPV DNA between patients and controls. Furthermore, the difference in the presence of HPV DNA between patients and controls was highly significant not only in those who had been found ill at enrolment (group A) but, most importantly, also in women who had developed the disease in the course of the follow up (groups B and C). Women positive for HPV DNA possessed HPV antibodies to VLP16, 18 and 33 significantly more often than those who were free of HPV DNA. CONCLUSION This indicated that healthy women who were positive for HPV DNA at enrolment were at an increased risk of developing cervical neoplasia (OR = 18.5; CI 5.9 to 57.6).

Abstract
To obtain information on the incidence and the clinical significance of infection with various types of the human papillomavirus (HPV) in cancer of the uterine cervix, we retrospectively examined the HPV status of 106 patients who had received radical radiotherapy for cervical cancer stages IB to IIIB. DNA was extracted from formalin-fixed, paraffin-embedded biopsies and PCR was carried out to identify HPV types 16, 18, 31, 35, 33 and 45. To detect additional HPV types, consensus PCR products were cloned and sequenced. A catalyzed signal-amplified colorimetric in situ hybridization was carried out in 84 of 106 specimens as a positive control. Response to therapy, progression-free survival (PFS) and cervical cancer-specific survival (CCSS) were the statistical endpoints. Survival analysis was carried out using univariate and multivariate analysis (Cox regression). Ninety-six patients (90.6%) were HPV-positive and 42/96 (43.7%) were positive for multiple HPV types. Eight patients had persistent disease after radiotherapy. From these 8 patients, 7 were infected with multiple HPV types and only 1 patient had an infection with a single HPV type. After a median follow up period of 50 months, patients with multiple HPV infection had a significantly shorter PFS and CCSS compared to those with single HPV infection (24.8% and 34.9% vs. 64% and 60.8%, Log rank, p < 0.01 and 0.04). In multivariate analysis, the presence of multiple HPV types (RR 1.9), node status (RR 2.3), tumor size (RR 3.2) and histologic type (RR 4.8) were independent prognostic factors of CCSS. Our results demonstrate that the presence of multiple HPV types is associated with poor response and with reduced survival in cervical cancer patients who receive radiotherapy as the primary treatment.

Abstract
The aim of this study was to retrospectively examine whether the occurrence of squamous cell carcinoma (SCC) antigen tumour marker in the serum has prognostic significance in operable SCC of the cervix at the International Federation of Gynaecology and Obstetrics (FIGO) stages IA2-IIB. A total of 129 patients who had undergone a radical hysterectomy for SCC of the uterine cervix at the Department of Gynecology of the Martin-Luther University, Halle-Wittenberg in 1991-2000 were included. SCC antigen (Ag) was measured by IMx SCC-Ag microparticle enzyme immunoassay (Abbott Laboratories, Abbott Park, IL, USA). To assess the prognostic value of SCC antigen in the serum, we used a step-by-step multivariate analysis based on the Cox proportional hazard regression model. Using a cut-off value of 3.0 ng/ml, we detected preoperative SCC antigen in the serum as an independent prognostic factor in SCC of the cervix, both for recurrence-free and overall survival (P=0.003 and 0.0078). In this retrospective analysis the value of the SCC antigen tumour marker correlates with prognosis in operable SCC of the cervix, independent of tumour size, pelvic nodal status, cervical stroma infiltration, parametrial spread and tumour grading.

Abstract
OBJECTIVES We wished to evaluate whether the presence of antibodies to HPV or to the HPV oncoproteins E6 and E7 or type of HPV DNA is related to prognosis among cervical cancer patients. METHODS Blood samples were drawn from 313 patients with incident, untreated cervical cancer on admission to two hospitals in Sweden. Patients were followed from enrollment in 1984-1991 until death or up to June 1999. Clinical information was obtained from a review of medical records. Survival and cause of death were ascertained from both medical records and population-based cancer registries. The correlation of survival with antibodies to HPV16, to oncoproteins E6 and E7, and to type of HPV DNA was evaluated using multivariate Cox regression analysis, including stage, age, histology, and hospital in the model. RESULTS Stage was the only significant prognostic factor influencing cervical cancer patient survival (OR = 3.62, 95% CI = 2.71-4.83). Age over 50 was associated with increased death rate among stage I-IIa patients (OR = 2.29, 95% CI = 1.12-4.68). Presence of antibodies to the oncoproteins E6 and E7 or to the HPV16 capsid or type of HPV DNA did not associate significantly with disease prognosis. CONCLUSIONS Antibodies to HPV16 capsids and to oncoproteins E6 and E7 or type of HPV DNA do not appear to be useful as indicators of cervical cancer prognosis.

Abstract
OBJECTIVE Infection with high-risk human papillomavirus (HPV) types such as HPV-16 is a major risk factor for the development of cervical cancer. HPV-16 capsid antibodies are detectable in approximately 50% of patients with HPV-16 DNA-positive cervical cancer. We investigated the prognostic significance of HPV capsid antibodies for survival in patients with cervical cancer in comparison with conventional clinicopathologic features such as staging, histologic grading, histology, age, and treatment modality. STUDY DESIGN Serum samples from 68 patients with cervical cancer and 65 healthy female control subjects were analyzed by enzyme-linked immunosorbent assay for HPV-specific immunoglobulin G (IgG) antibodies to baculovirus expressed HPV-6, HPV-11, HPV-16, and HPV-18 L1 virus-like particles (VLPs). RESULTS HPV-16 L1 IgG antibodies were detectable in 6 of 65 (9%) of the control subjects and in 19 of 68 (28%) of the patients with cervical cancer (P =.007). In the subgroup of patients with HPV-16 DNA-positive cervical cancer (comprising 50% of the investigated samples), HPV-16 L1 antibodies were detected in 40%. HPV-16 L1 seropositivity was in univariate and multivariate analysis in addition to International Federation of Gynecology and Obstetrics stage, the only independent positive prognostic factor for overall survival (P =.01). CONCLUSION Antibodies to HPV-16 L1 were found to be an independent prognostic factor for overall survival in patients with cervical cancer. Thus, HPV-16 infection may be involved not only in oncogenesis but also in tumor development and behavior.

Abstract
The causal role of human papillomavirus infections in cervical cancer has been documented beyond reasonable doubt. The association is present in virtually all cervical cancer cases worldwide. It is the right time for medical societies and public health regulators to consider this evidence and to define its preventive and clinical implications. A comprehensive review of key studies and results is presented.

Abstract
OBJECTIVE The present study was designed to analyse the relationship between apoptosis related proteins (bcl-2 and bax), tumour suppressor protein p53, proliferation markers (PCNA and mitotic index), human papillomavirus (HPV) and angiogenesis in cervical cancer and their impact on clinical outcome. STUDY DESIGN Tumours from 111 patients were assessed by immunohistochemistry for the expression of bcl-2, bax, p53 and PCNA, by PCR for the presence of HPV-DNA, for the quantification of the mitotic index and the microvessel density (CD 31). The results were correlated with various histopathologic characteristics and survival. RESULTS The multiple Cox's regression analysis for overall survival of all prognostic variables gave as best model: bcl-2 (P<0.001), lymphovascular permeation (P=0.004), mitotic index (P=0.019), tumour grade (P=0.048) and FIGO stage (P=0.070). Subanalysis was performed for the patients where the lymph node status was known (n=79). Adding the lymph node status gave as best model for overall survival bcl-2 (P=0.001), lymphovascular permeation (P=0.003) and mitotic index (P=0.044). However, they hardly influenced the association. CONCLUSION In the apoptotic pathway of cervical cancer, bcl-2 is one of most important proteins. It can probably not only mediate cell death but also regulate cell growth. A better understanding of their relations will probably provide the basis for more rational cancer therapies in the future.

Abstract
PURPOSE To determine the association between human papillomavirus (HPV) type and prognosis of patients with invasive cervical carcinoma. PATIENTS AND METHODS Patients diagnosed with International Federation of Gynecology and Obstetrics (FIGO) stage IB to IV cervical cancer between 1986 and 1997 while residents of three Washington State counties were included (n = 399). HPV typing was performed on paraffin-embedded tumor tissue using polymerase chain reaction methods. Patients were observed for a median of 50.8 months. Total mortality (TM) and cervical cancer-specific mortality (CCSM) were determined. Hazards ratios (HR) adjusted for age, stage, and histologic type were estimated using multivariable models. RESULTS Eighty-six patients had HPV 18-related tumors and 210 patients had HPV 16-related tumors. Cumulative TM among patients with HPV 18-related tumors and among patients with HPV 16-related tumors were 33.7% and 27.6%, respectively; cumulative CCSM in these two groups were 26.7% and 18.1%, respectively. Compared with patients with HPV 16-related cancers, patients with HPV 18-related cancers were at increased risk for TM (HR(TM), 2.2; 95% confidence interval [CI], 1.3 to 3.6) and CCSM (HR(CCSM), 2.5; 95% CI, 1.4 to 4.4). The HPV18 associations were strongest for patients with FIGO stage IB or IIA disease (HR(TM), 3.1; 95% CI, 2.3 to 4.2; and HR(CCSM), 5.8; 95% CI, 3.9 to 8.7), whereas no associations were observed among patients with FIGO stage IIB to IV disease. Virtually identical associations were found in the subset of patients with squamous cell carcinoma (n = 219). CONCLUSION HPV 18-related cervical carcinomas, particularly those diagnosed at an early stage, are associated with a poor prognosis. Elucidating the mechanism or mechanisms underlying this association could lead to new treatment approaches for patients with invasive cervical carcinoma.

Abstract
The objective of this study was to assess whether the presence of human papillomavirus (HPV) DNA and/or several genotypes of HPV DNA in cervical cancer are correlated with several clinicopathologic parameters of well-defined prognostic significance and whether virologic parameters are predictors of long-term survival in cancer patients. Two hundred twenty three cases of cervical cancer patients included in this retrospective study underwent follow-up evaluation. Survival and cause of death were examined for 204 (91.4%) patients, with a mean follow-up time of 4.4 years. HPV DNA was detected using the highly sensitive polymerase chain reaction (PCR) method followed by HPV DNA sequencing for HPV genotyping. These results were correlated with well-defined clinicopathologic parameters and survival data. HPV DNA was detected by PCR in 150 of 193 (73.4%) tissue specimens of cervical cancer patients. DNA sequence analysis revealed the presence of HPV 16 (n = 68, 45.3%), HPV 18 (n = 49, 32.6%) and rare HPV types (n = 33, 22.1%). HPV genotypes correlated significantly with histologic tumor types, node status, tumor oxygenation, blood vessel invasion, and lymph space involvement. The presence of HPV DNA in cervical cancer as well as the genotype of HPV 16 could also be confirmed as significant prognostic factors in the univariate Cox regression analysis (RR 2.856, P < 0.003 resp. RR 3.444, P < 0.0001). In the multivariate analysis, however, HPV DNA status failed to be of prognostic relevance. Exclusively HPV 16 appears to have an independent impact on the overall survival in cervical patients (RR 3.653, P < 0.002). We conclude that the detection of HPV 16 genotype may play an important adjunct role in assessing prognosis of cervical cancer patients. The clinical impact of the presence of HPV DNA in primary tumors of uterine cervix remains to be investigated in further studies, and the exact mechanisms by which HPV influences the prognosis of cervical cancer patients have to be defined.

Abstract
A group of 21 cervical-carcinoma patients was followed longitudinally. All patients had undergone intensive radiotherapy. In the course of a more than 5-year observation period, 2 patients died of cervical cancer, 1 from other causes, 3 were lost from follow-up, and 15 survived without any signs of the disease. Sera taken before, up to 17 months after and more than 5 years after the start of therapy, were tested by ELISA for IgG antibodies reactive with a broad spectrum of HPV-derived antigens, glycoprotein G of HSV 2, whole virion antigen of HCMV, and a synthetic peptide corresponding to the immuno-dominant region of EBNA 1. The therapy was associated with a marked decrease in E2 and E7 antibodies in nearly all patients possessing pre-existing antibodies; the changes in VLP antibody levels in the treated women were more rare and less pronounced. In the course of the observation period, seroconversion to gG HSV2 positivity was seen in 5 patients, while, a marked increase in pre-existing gG HSV2 antibodies was observed in 5 out of 7 originally seropositive patients. At enrollment, only 2 patients were free of HCMV antibody and only 1 was free of EBNA1 antibody; no seroconversion relative to either antigen was seen during the observation period.

Abstract
BACKGROUND Human papillomavirus (HPV) is the main cause of cervical neoplasia. Because few population-based studies have investigated the prevalence of type-specific infection in relation to cervical disease, we studied a high-risk population, estimating the prevalence of HPV infection and the risk associated with various HPV types. METHODS We screened 9175 women in Guanacaste, Costa Rica, to obtain a referent standard final diagnosis, and tested 3024 women for more than 40 types of HPV with a polymerase chain reaction-based system. RESULTS Among women with normal cytology, HPV infections peaked first in women younger than 25 years, and they peaked again at age 55 years or older with predominantly non-cancer-associated types of HPV and uncharacterized HPV types. Low-grade squamous intraepithelial lesions (LSILs) (n = 189) decreased consistently with age. The prevalence of high-grade squamous intraepithelial lesions (HSILs) (n = 128) peaked first around age 30 years and again at age 65 years or older. Seventy-three percent of LSILs were HPV positive, with HPV16 being the predominant type (16% of positive subjects). HPV was found in 89% of HSILs and 88% of cancers, with HPV16 being strongly predominant (51% and 53% of positive subjects). Virtually all HSILs and cancers had cancer-associated HPV types, with high odds ratios (ORs) and attributable fractions around 80%. Risk for HPV16 was particularly high (OR for HSILs = 320, 95% confidence interval [CI] = 97-1000; OR for cancer = 710, 95% CI = 110-4500). CONCLUSIONS We confirm the early decline of HPV infection with age but note increased prevalence after menopause, which could be related to a second peak of HSILs, an observation that warrants further investigation. At least 80% of HPVs involved in cervical carcinogenesis in this population have been characterized. Polyvalent vaccines including the main cancer-associated HPV types may be able to prevent most cases of cervical disease in this region.

Abstract
HPV types are carcinogenic agents in cervical cancer. This view is supported by epidemiological and biological evidence. The oncogenic products and capsid proteins of high risk HPV types are potential targets against which effective immunity may be generated by vaccination. Both therapeutic and prophlylactic immunisation are potential strategies to deal with the widespread problem of HPV infection and possibly established cervical neoplasia. Clinical trials are now underway to evaluate candidate vaccines.

Abstract
Sera collected in the course of a prospective study carried out in Prague in 1975-1983 were assayed for the presence of human papillomavirus (HPV) antibodies. Women with cervical neoplasia proven by biopsy at enrollment possessed antibodies to peptides derived from E2, E4 and E7 proteins of HPV16 and to virus-like particles (VLPs) of HPV16, -18 and -33 significantly more frequently than matched controls. Women without cervical neoplasia at enrollment who developed the disease in the course of the study differed from matched controls by a higher prevalence of antibodies against VLPs of HPV16 and -18 but not against early antigens of HPV16. In 19 of the latter subjects, paired serum specimens were tested, the first samples having been taken at enrollment and the second at diagnosis. Development of the disease was associated with seroconversion from negativity to positivity to at least one HPV antigen in 11 (57.9%) women.

Abstract
Cancer of the cervix is the second most common cancer in women after cancer of the breast, and the commonest in developing countries. In the last decade the etiology of cervical cancer has been unequivocally established--over 90% of the cases in all countries are related to infections to some strains of human papillomavirus (HPV). These infections are common in young age groups and resolve spontaneously in most instances. The typical HPV deoxyribonucleic acid (DNA) prevalence after the third decade lies between five and 15% of women. These findings form the basis of new strategies for screening and prevention of cervical cancer.
