RESUMO

BACKGROUND: To determine whether age is a barrier against acceptability of cervicovaginal self-sampling in screening for cervical cancer at two gynecology outpatient clinics. METHODS: This is a cross-sectional study involving 116 women over 21 years of age with an abnormal Pap smear. Clinical and laboratorial data were recorded in electronic files. Women received detailed self-collection instructions. After the self-sampling procedure (Evalyn Brush®), women were instructed to answer a questionnaire about vaginal self-sampling acceptability that consisted of seven multiple-choice items. The participants were divided into three age brackets: 21 to 29 years, 30 to 49 years, and 50 years and over. Chi-square, Fischer exact, Kolmogorov-Smirnov and Kruskal-Wallis tests were used. RESULTS: The analysis of the participants' perception of the procedure stratified according to age groups showed a decline in the fear of hurting oneself during the procedure as age increased. Most participants reported that it was very easy to understand how to use the self-sampling brush and that it was easy to use it. Most of them were neither embarrassed nor afraid of getting hurt during the procedure. The majority preferred self-sampling to collection by a healthcare professional. The main reason was practicality: the possibility of choosing the place and time for sampling. CONCLUSIONS: The participating women found self-collection simple to understand and easy to accept regardless of age. The younger women indicated more fear and discomfort in self-sampling, which points to the need for attraction strategies that are more appealing to the younger generations.

RESUMO

The objective of this study was to evaluate human papillomavirus (HPV) and Chlamydia trachomatis (CT) infections in RA patients pre- and post-TNF blocker. Fifty female RA patients (ACR criteria), who were eligible to anti-TNF therapy [n = 50 at baseline (BL) and n = 45 after 6 months of treatment (6 M)], and 50 age-matched healthy controls were prospectively enrolled. They were assessed for demographic data, gynecologic, sexual, cervical cytology and histological evaluations, disease parameters and current treatment. HPV DNA and CT DNA testing in cervical specimens were done using Hybrid Capture II assays. At BL, the median current age of RA patients and controls was 49 (18-74) versus 49 (18-74) years, p = 1.0. A trend of lower frequency of HPV infection was observed in AR patients pre-anti-TNF compared with controls (14 vs. 30%, p = 0.054). Further evaluation of AR patients with and without HPV infection before anti-TNF therapy showed that the former group had higher frequency of sexual intercourses (100 vs. 48%, p = 0.014), higher median number of sexual partners [1 (1-1) vs. 0 (0-1), p = 0.032] and higher frequency of abnormal cervical cytology (43 vs. 7%, p = 0.029). Current age, disease duration, disease parameters and treatments were alike in both groups (p > 0.05). At 6 M after TNF blockage, HPV infection remained unchanged in five patients, whereas two became negative and one additional patient turned out to be positive (p = 1.0). CT infection was uniformly negative in RA patients pre- and post-TNF blockage and in controls. Anti-TNF does not seem to increase short-term risk of exacerbation and/or progression of HPV and CT infections in RA patients.

RESUMO

OBJECTIVE: To compare the effects of fractional CO2 laser and microablative fractional radiofrequency treatment with promestriene topical estrogen on sexual function and genitourinary syndrome of menopause symptoms. METHODS: This was a prospective randomized open-label clinical trial conducted with 62 postmenopausal women assigned to three intervention groups: a) topical promestriene for 90 days (n = 17); b) fractional CO2 laser treatment (n = 24); and c) microablative fractional radiofrequency treatment (n = 21). Each of the latter two groups underwent three treatment sessions at 4-week intervals. At baseline and at the end of the study, all participants had a gynecological examination that included vaginal pH measurement, and the completion of the Vaginal Symptom Score, the Vaginal Health Index, and the Female Sexual Function Index. For the energy treatment groups, adverse effects were evaluated after each session. Group homogeneity was assessed at baseline, and results were evaluated over time (from baseline to the end of treatment) and between groups over time. RESULTS: All baseline parameters were similar among studied groups. At the end of the study, all 3 treatments had produced similar effects: a reduction of vaginal pH, and an improvement of vulvovaginal symptoms (Vaginal Symptom Score and Vaginal Health Index scores) as well as sexual function (higher total Female Sexual Function Index scores, and in the desire, arousal, lubrication and pain domain scores), with no differences observed between groups. Side-effects were slight for both energy treatment groups, mainly represented by vaginal discharge. CONCLUSION: The present study suggests that the two energy treatments were efficient along with promestriene at improving postmenopausal genitourinary and sexuality symptoms. Clinical trial identification numberNCT04717245.

RESUMO

OBJECTIVES: Robust evidence now supports human papillomavirus (HPV) testing as a more effective option to screening and as more sensitive than cytology in detecting high-grade cervical intraepithelial neoplasia . Our goal was to analyze the performance of the Hybrid Capture II (HC2) assay for high-risk HPV (hrHPV) in women undergoing gynecological examination at a public health hospital as part of the evaluation of HPV screening as an alternative or complement to cytology. STUDY DESIGN: This analysis is a subset of a cross-sectional study carried out at a large public hospital serving a predominantly low-resource population. A total of 705 women were enrolled; the sensitivity and specificity of each test were estimated and compared. RESULTS: The analysis identified 272 hrHPV-positive women (mean age 36.3 years) and 433 hrHPV-negative women (mean age 41.2 years). HPV testing showed a significantly increased sensitivity of the HC2 assay versus cytology (84.5 vs. 69.7%; p < 0.0001) but a lower specificity (49.90 vs. 88.78%; p < 0.0001). CONCLUSION: The combination of both methods seems to be useful in improving detection of cervical lesions.

RESUMO

BACKGROUND: The development of efficient strategies for managing high-risk human papillomavirus (HR-HPV)-positive women is a major challenge when human papillomavirus-based primary screening is being performed. The objectives of this study were to evaluate the comparative effectiveness of HR-HPV testing based on self-collection (SC) and HR-HPV testing based on collection by a health professional (HP) and to assess the potential usefulness of HR-HPV testing combined with testing with the biomarkers p16/Ki-67, α-mannosidase, and superoxide dismutase 2 (SOD2). METHODS: This was a cross-sectional study of 232 women admitted for colposcopy because of an abnormal Papanicolaou smear. The collected material underwent liquid-based cytology, HR-HPV detection, and immunocytochemical testing (p16/Ki-67, α-mannosidase, and SOD2). The gold standard was the histopathological result; the positive reference was CIN2+. RESULTS: The overall accuracy of HR-HPV testing was 76.6%; the results for the SC group (78.1%) and the HP group (75.2%) were similar. The positive predictive values (HP, 76.5%; SC, 80.0%), the negative predictive values (HP, 66.7%; SC, 64.3%), the positive likelihood values (HP, 1.35; SC, 1.36), and the negative likelihood values (HP, 0.21; SC, 0.19) were also similar. p16/Ki-67 showed higher sensitivity than the other 2 biomarkers: 78.1% versus 45.8% for α-mannosidase and 44.5% for SOD2. The specificities of the biomarkers were equivalent: 71.4% for p16/Ki-67, 77.8% for α-mannosidase, and 71.2% for SOD2. In the HP group, accuracy also leaned more heavily toward the final score (using α-mannosidase and SOD2) without statistical significance (80.8% vs 77.9%). The contrast with the SC group yielded the same level of accuracy. CONCLUSIONS: SC, when associated with testing with biomarkers, is as accurate as collection by HPs in the detection of women at risk for cervical cancer.

RESUMO

INTRODUCTION: Solid organ transplant (SOT) recipients are at increased risk of Human Papillomavirus (HPV) persistent infection and disease. This study aimed to evaluate HPV seroprevalence, cervical HPV prevalence, genotype distribution, and frequency of HPV-related cervical lesions in SOT recipients in comparison to immunocompetent women. METHODS: Cross-sectional study including SOT and immunocompetent women aged 18 to 45 years who denied previous HPV-related lesions. Cervical samples were screened for HPV-DNA by a polymerase chain reaction (PCR)-based DNA microarray system (PapilloCheck®) and squamous intraepithelial lesions (SIL) by liquid-based cytology. A multiplexed pseudovirion-based serology assay (PsV-Luminex) was used to measure HPV serum antibodies. RESULTS: 125 SOT and 132 immunocompetent women were enrolled. Cervical samples were collected from 113 SOT and 127 immunocompetent women who had initiated sexual activity. HPV-DNA prevalence was higher in SOT than in immunocompetent women (29.6% vs. 20.2%, p = 0.112), but this difference was not statistically significant. High-risk (HR)-HPV was significantly more frequent in SOT than in immunocompetent women (19.4% vs. 7.9%, p = 0.014). Simultaneous infection with ≥2 HR-HPV types was found in 3.1% of SOT and 0.9% of immunocompetent women. HPV seropositivity for at least one HPV type was high in both groups: 63.8% of 105 SOT and 69.7% of 119 immunocompetent women (p = 0.524). Low-grade (LSIL) and high-grade SIL (HSIL) were significantly more frequent in SOT (9.7% and 5.3%, respectively) than in immunocompetent women (1.6% and 0.8%, respectively) (p = 0.001). CONCLUSIONS: These results may reflect the increased risk of HPV persistent infection and disease progression in SOT women due to chronic immunosuppression.

RESUMO

OBJECTIVES: This study aimed to verify whether human papillomavirus (HPV) testing after conization treatment has some potential usefulness for predicting patients' outcome. STUDY DESIGN: One hundred and twenty women were treated for HSIL by conization with large loop excision of the transformation zone (LLETZ). Cytology, colposcopy-guided biopsy, and hybrid capture 2 (HC2) HPV DNA tests were performed before the surgical procedure and every 6 months for 2 years at follow-up. RESULTS: More than 90% of the patients tested positive for high-risk HPV prior to the surgical intervention. Six months after the cervical conization, 74.75% of the patients tested negative for high-risk HPV DNA, and 19.41% were positive. Of the women who were HC2 negative, 72 showed normal cytological smears, 3 ASC-US, 2 LSIL, and 1 HSIL. Of those who were HC2 positive, 8 showed normal smears, 2 ASC-US, 2 ASC-H, 5 LSIL, and 1 case had HSIL, AGC, and squamous cells invasive carcinoma. Clinically, the HSIL case with a negative HPV test did not show any sign of high-grade lesions, and the clinical follow-up did not show residual lesions. CONCLUSIONS: Negative HPV tests correlated with freedom from high-grade disease after 2 years of postconization follow-up, which strongly suggests that negative HPV tests predict the absence of cervical disease.

RESUMO

OBJECTIVE: To evaluate the effectiveness of electrosurgery fulguration as a treatment for Bartholin's gland cysts. Retrospective study with a comparative control group performed on Hospital Brigadeiro and in the Disciplina de Ginecologia do Departamento de Obstetrícia e Ginecologia, Hospital das Clínicas, Faculdade de Medicina da Universidade de São Paulo from February 2005 to March 2009. Patients: Patients with Bartholin's gland cyst were divided into three treatment groups: group 1 electrosurgery (n=169 cases); group 2 - gland excision with the conventional technique using a cold scalpel (n = 51 cases); group 3 - marsupialization (n=11 cases). We reviewed the clinical and surgical history, physical examination, description of the surgical technique, postoperative results (success and complications), and follow-up data. RESULTS: There is no difference between groups in relation to intraoperative bleeding, hematoma, and complete healing in a single treatment session. However, electrosurgery shows the lower percentage of recurrences 18 (10,7%) compared to the Marsupialization technique (group 3, p=.031). Recurrences occurred in 18 (10,7%), 3 (5,9%), and 4 (36,4%) cases. After retreatment by the same technique, there was a complete cure rate of 90% (152/169) for group 1, and 98% (50/51) for group 2. The cost of group 1 was lower than that of other groups. CONCLUSION: The fulguration with electrosurgery of the capsule of Bartholin's cyst is an effective method of treatment, andthe cost of this technique is lower than the conventional technique and marsupialization.

RESUMO

BACKGROUND: To evaluate human papillomavirus (HPV), Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) infections in juvenile idiopathic arthritis (JIA) patients. METHODS: After exclusion, 33 female adolescent and young JIA patients (ILAR criteria) and 28 healthy controls were selected for this study. Demographic data, gynecological, sexual function, cervical cytology and histological abnormalities were evaluated. JIA clinical/laboratorial parameters and treatment were also assessed. HPV-DNA, CT-DNA and NG-DNA testing in cervical specimens were performed by Hybrid Capture 2 assays. RESULTS: The mean current age was similar in JIA patients and controls (23.3 ± 6.24 vs. 26.1 ± 6.03 years, p = 0.09). The frequencies of sexual intercourse (76% vs. 89%, p = 0.201) and abnormal cervical cytology (24% vs. 11%, p = 0.201) were similar in JIA compared to controls. The higher frequency of HPV infection in JIA patients than controls (30% vs. 11%, p = 0.155) did not reach statistical significance. CT (0% vs. 7%, p = 0.207) and NG infections (0% vs. 4%, p = 0.459) were also alike in both groups. Further evaluation of JIA patients with abnormal and normal cervical cytology showed that the former group had a higher frequency of HPV infection (87% vs. 12%, p = 0.0002) with a low frequency of HPV vaccination (0% vs. 8%, p = 1.0). No differences were evidenced between these two JIA groups regarding demographic data, sexual function and clinical/laboratorial parameters. The frequencies of methotrexate (p = 0.206) and biological agent use (p = 0.238) were similar in both JIA groups. CONCLUSIONS: To our knowledge, this was the first study to assess lower genital infections in JIA patients allowing the identification of HPV as main cause of cervical dysplasia. Methotrexate and biological agents do not seem to increase risk of lower genital tract infections in JIA patients.

RESUMO

Cervical cancer continues to be a public health problem in developing countries. Previous studies have shown that cervical cancer cells display markers of aerobic glycolysis, indicating that these tumors are likely to secrete lactate. Mostly, lactate is recognized as a molecule capable of suppressing immune responses, through inhibition of T cells, Mϕs, and dendritic cells. We and others have previously shown that Mϕs are frequent cells infiltrating cervical cancers with the ability to inhibit antitumor immune responses and promote tumor growth through angiogenesis. Here, we have tested the hypothesis that lactate, secreted by cervical cancer cells, can modulate Mϕ phenotype. First, we showed higher lactate plasma concentrations in patients with increasing cervical lesion grades, with maximum concentration in the plasma of cancer patients, which supported our hypothesis. We then inhibited lactate production in tumor cell spheroids established from cervical cancer derived cell lines, using the lactate dehydrogenase inhibitor, oxamate, prior to co-culture with monocytes. Lactate mediated part of the crosstalk between tumor cells and Mϕs, promoting secretion of IL-1ß, IL-10, IL-6, and up-regulation of hypoxia induced factor-1α expression, and down-regulation of p65-NFκB phosphorylation in Mϕs. We also showed that Mϕs from co-cultures treated with oxamate were better inducers of T cell activation. Of note, experiments performed with inhibition of the monocarboxylate transporters rendered similar results. Our data confirms the hypothesis that lactate, secreted by cervical tumor cells, influences the phenotype of tumor Mϕs, promoting a suppressive phenotype.

RESUMO

Cervical cancer is the last stage of a series of molecular and cellular alterations initiated with Human Papillomavirus (HPV) infection. The process involves immune responses and evasion mechanisms, which culminates with tolerance toward tumor antigens. Our objective was to understand local and systemic changes in the interactions between HPV associated cervical lesions and the immune system as lesions progress to cancer. Locally, we observed higher cervical leukocyte infiltrate, reflected by the increase in the frequency of T lymphocytes, neutrophils and M2 macrophages, in cancer patients. We observed a strong negative correlation between the frequency of neutrophils and T cells in precursor and cancer samples, but not cervicitis. In 3D tumor cell cultures, neutrophils inhibited T cell activity, displayed longer viability and longer CD16 expression half-life than neat neutrophil cultures. Systemically, we observed higher plasma G-CSF concentration, higher frequency of immature low density neutrophils, and tolerogenic monocyte derived dendritic cells, MoDCs, also in cancer patients. Interestingly, there was a negative correlation between T cell activation by MoDCs and G-CSF concentration in the plasma. Our results indicate that neutrophils and G-CSF may be part of the immune escape mechanisms triggered by cervical cancer cells, locally and systemically, respectively.

RESUMO

This study characterized and related yeasts of the genus Candida isolated from vaginal mucous membranes of women with lesions caused by high-risk HPV for cervical cancer. Forty-two women treated at the Lower Genital Tract Pathology Clinic of the University of São Paulo Medical School Hospital of Clinics were examined, with 30 high-grade (G1) uterine lesions with a mean age of 36.5 years ± 11. 1 and 12 with low grade (G2) uterine lesions with a mean age of 34.7 years ± 15.5. Clinical conditions and laboratory data on HPV were collected from patients' medical records; the socio-demographic data obtained from an appropriate questionnaire. For the study of association between the variables, Odds Ratio analysis was used from the STATA 13.1 program. Patients G1 had a higher prevalence for diabetes and the results indicated 27% prevalence of Candida spp. in vaginal mucosa, in G2 this was 33% in vaginal mucosa. Among the species found in vaginal mucosa of patients, Candida albicans was the most isolated with 88%, followed by C. tropicalis (8%) and C. glabrata (4%). The strains of C. albicans isolated from mucosa presented sensitivity to all antifungal agents tested, unlike the C. tropicalis strain isolated in G2 in vaginal mucosa, which presented a resistance profile to fluconazole. Thus, monitoring and supervision through clinical and laboratory testing of HPV patients is important, reinforcing the need for care, treatment and prevention of HPV-related infections and Candida spp.

RESUMO

SUMMARY OBJECTIVE To evaluate the effectiveness of electrosurgery fulguration as a treatment for Bartholin's gland cysts. DESIGN Retrospective study with a comparative control group performed on Hospital Brigadeiro and in the Disciplina de Ginecologia do Departamento de Obstetrícia e Ginecologia, Hospital das Clínicas, Faculdade de Medicina da Universidade de São Paulo from February 2005 to March 2009. Patients: Patients with Bartholin's gland cyst were divided into three treatment groups: group 1 electrosurgery (n=169 cases); group 2 - gland excision with the conventional technique using a cold scalpel (n = 51 cases); group 3 - marsupialization (n=11 cases). We reviewed the clinical and surgical history, physical examination, description of the surgical technique, postoperative results (success and complications), and follow-up data. RESULTS There is no difference between groups in relation to intraoperative bleeding, hematoma, and complete healing in a single treatment session. However, electrosurgery shows the lower percentage of recurrences 18 (10,7%) compared to the Marsupialization technique (group 3, p=.031). Recurrences occurred in 18 (10,7%), 3 (5,9%), and 4 (36,4%) cases. After retreatment by the same technique, there was a complete cure rate of 90% (152/169) for group 1, and 98% (50/51) for group 2. The cost of group 1 was lower than that of other groups. CONCLUSION The fulguration with electrosurgery of the capsule of Bartholin's cyst is an effective method of treatment, andthe cost of this technique is lower than the conventional technique and marsupialization.


RESUMO OBJETIVO Avaliar a eficácia da fulguração da eletrocirurgia como tratamento para os cistos da glândula de Bartholin. MÉTODOS Estudo retrospectivo, grupo controle comparativo realizado no Hospital Brigadeiro e disciplina de Ginecologia do Departamento de Obstetrícia e Ginecologia do Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo, de fevereiro de 2005 a março de 2009. Pacientes com cisto de glândula de Bartholin foram divididos em três grupos de tratamento: grupo 1 - eletrocirurgia (n = 169 casos); grupo 2 - excisão da glândula com técnica convencional utilizando bisturi frio (n = 51 casos); grupo 3 - marsupialização (n = 11 casos). Revisamos a história clínica e cirúrgica, o exame físico, a descrição da técnica cirúrgica, os resultados pós-operatórios (sucesso e complicações) e os dados de acompanhamento. RESULTADOS Não há diferença entre os grupos em relação ao sangramento intraoperatório, hematoma e cicatrização completa em uma única sessão de tratamento. No entanto, a eletrocirurgia mostrou o percentual mínimo de recidivas, 18 (10,7%), em relação à técnica de marsupialização (grupo 3, p = 0,031). Recorrências ocorreram em 18 (10,7%), três (5,9%) e quatro (36,4%) casos. Após o retratamento pela mesma técnica, houve taxa de cura completa: 90% (152/169) para o grupo 1 e 98% (50/51) para o grupo 2. O custo do grupo 1 foi menor do que os dos outros grupos. CONCLUSÃO A fulguração com eletrocirurgia da cápsula do cisto de Bartholin é um método efetivo de tratamento, mas o custo dessa técnica é menor do que a técnica de convenção e a marsupialização.

RESUMO

Invasive cervical cancer (ICC) is the third most frequent cancer among women worldwide and is associated with persistent infection by carcinogenic human papillomaviruses (HPVs). The combination of large populations of viral progeny and decades of sustained infection may allow for the generation of intra-patient diversity, in spite of the assumedly low mutation rates of PVs. While the natural history of chronic HPVs infections has been comprehensively described, within-host viral diversity remains largely unexplored. In this study we have applied next generation sequencing to the analysis of intra-host genetic diversity in ten ICC and one condyloma cases associated to single HPV16 infection. We retrieved from all cases near full-length genomic sequences. All samples analyzed contained polymorphic sites, ranging from 3 to 125 polymorphic positions per genome, and the median probability of a viral genome picked at random to be identical to the consensus sequence in the lesion was only 40%. We have also identified two independent putative duplication events in two samples, spanning the L2 and the L1 gene, respectively. Finally, we have identified with good support a chimera of human and viral DNA. We propose that viral diversity generated during HPVs chronic infection may be fueled by innate and adaptive immune pressures. Further research will be needed to understand the dynamics of viral DNA variability, differentially in benign and malignant lesions, as well as in tissues with differential intensity of immune surveillance. Finally, the impact of intralesion viral diversity on the long-term oncogenic potential may deserve closer attention.

RESUMO

INTRODUCTION: Infections are frequent in childhood-systemic lupus erythematosus (C-SLE) patients, including human papillomavirus (HPV). HPV infection may cause genital and anal warts named condyloma acuminatum (CA). To our knowledge, none case was reported and the prevalence of CA in C-SLE population was not performed. CASE REPORTS: From January 1983 to May 2012, 5,682 patients were followed at the Pediatric Rheumatology Unit from of our University Hospital and 289 (5%) of them met the American College of Rheumatology classification criteria for C- SLE. Four (1.4%) of our female patients had CA. The median age at diagnosis was 13 years. Three of them were sexually active and all of them had active disease and had high risk HPV anogenital warts. Pap smears showed low-grade squamous intraepithelial lesion, guided biopsies identified chronic cervicitis, vulvar, vaginal, anal and/or cervix intraepithelial neoplasia. All of them were under corticosteroids and immunosuppressive drugs. The visible genital warts lesions were eradicated. DISCUSSION: Our patients requires rigorous gynecologic follow-up due to the severe anogenital dysplasia. HPV vaccine should be indicated in all C-SLE prior to sexual activity.

RESUMO

Abstract Background: To evaluate human papillomavirus (HPV), Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) infections in juvenile idiopathic arthritis (JIA) patients. Methods: After exclusion, 33 female adolescent and young JIA patients (ILAR criteria) and 28 healthy controls were selected for this study. Demographic data, gynecological, sexual function, cervical cytology and histological abnormalities were evaluated. JIA clinical/laboratorial parameters and treatment were also assessed. HPV-DNA, CT-DNA and NG-DNA testing in cervical specimens were performed by Hybrid Capture 2 assays. Results: The mean current age was similar in JIA patients and controls (23.3 ± 6.24 vs. 26.1 ± 6.03 years, p = 0.09). The frequencies of sexual intercourse (76% vs. 89%, p = 0.201) and abnormal cervical cytology (24% vs. 11%, p = 0.201) were similar in JIA compared to controls. The higher frequency of HPV infection in JIA patients than controls (30% vs. 11%, p = 0.155) did not reach statistical significance. CT (0% vs. 7%, p = 0.207) and NG infections (0% vs. 4%, p = 0.459) were also alike in both groups. Further evaluation of JIA patients with abnormal and normal cervical cytology showed that the former group had a higher frequency of HPV infection (87% vs. 12%, p = 0.0002) with a low frequency of HPV vaccination (0% vs. 8%, p = 1.0). No differences were evidenced between these two JIA groups regarding demographic data, sexual function and clinical/laboratorial parameters. The frequencies of methotrexate (p =0.206) and biological agent use (p =0.238) were similar in both JIA groups. Conclusions: To our knowledge, this was the first study to assess lower genital infections in JIA patients allowing the identification of HPV as main cause of cervical dysplasia. Methotrexate and biological agents do not seem to increase risk of lower genital tract infections in JIA patients.

RESUMO

Cervical cancer and its precursor lesions represent a significant public health problem for developing and less-developed countries. Cervical carcinogenesis is strongly correlated with persistent high-risk human papillomavirus (HPV) infection, which is mostly associated with expression of the p16 and E6 HPV-related proteins. The aim of this present study was to determine the expression of the p16 and E6 proteins in females with high-grade lesions treated with conization, and to discuss the role of these proteins as prognostic markers following treatment. In total, 114 females were treated for high-grade cervical intraepithelial neoplasia (CIN, grades 2/3) by conization with large loop excision of the transformation zone (LLETZ). Following surgery, the patients returned within 30-45 days for post-operative evaluation. A follow-up was conducted every 6 months for 2 years. At each follow-up appointment, a Pap smear, colposcopy and HPV DNA test were performed. E6 and p16 immunohistochemical tests were conducted on the surgical specimens. The positive expression of p16 was correlated with the presence of lesions with increased severity in the surgical specimens (P= 0.0001). The expression of E6 did not demonstrate the same correlation (P=0.131). The HPV DNA hybrid, collected in the first post-operative consultation as a predictor of the cytological abnormalities identified at the 24-month follow-up assessment, presented a sensitivity of 55.6%, a specificity of 84.8%, a positive predictive value of 33.3% and a negative predictive value of 93.3%. The role of p16INK4A as a marker of CIN was also demonstrated; the expression of p16 and E6, however, did not appear to be of any prognostic value in predicting the clearance of high-risk HPV following conization. A negative hybrid capture test was correlated with a disease-free outcome.
