RESUMO

In France, about 2000 new cases of anal cancer are diagnosed annually. Squamous cell carcinoma is the most common histological type, mostly occurring secondary to persistent HPV16 infection. Invasive cancer is preceded by precancerous lesions. In addition to patients with a personal history of precancerous lesions and anal cancer, three groups are at very high risk of anal cancer: (i) men who have sex with men and are living with HIV, (ii) women with a history of high-grade squamous intraepithelial lesions (HSILs) or vulvar HPV cancer, and (iii) women who received a solid organ transplant more than 10 years ago. The purpose of screening is to detect HSILs so that they can be treated, thereby reducing the risk of progression to cancer. All patients with symptoms should undergo a proctological examination including standard anoscopy. For asymptomatic patients at risk, an initial HPV16 test makes it possible to target patients at risk of HSILs likely to progress to cancer. Anal cytology is a sensitive test for HSIL detection. Its sensitivity is greater than 80% and exceeds that of proctological examination with standard anoscopy. It is indicated in the event of a positive HPV16 test. In the presence of cytological abnormalities and/or lesions and a suspicion of dysplasia on clinical examination, high-resolution anoscopy is indicated. Performance is superior to that of proctological examination with standard anoscopy. However, this technique is not widely available, which limits its use. If high-resolution anoscopy is not possible, screening by a standard proctological examination is an alternative. There is a need to develop high-resolution anoscopy and triage tests and to evaluate screening strategies.

RESUMO

In France, recent advances in cervical cancer screening include an organized cervical cancer-screening program and the introduction of HPV testing as a first-line test for women aged 30-65 years. The HPV test, performed on a cervical smear taken by a health professional, could also be performed on a vaginal self-sample in certain indications. The detection kits used to test for HPV should target high-risk HPV, be validated for screening and meet the performance requirements for this indication. Although no longer used as a first-line test in women aged 30-65 years, cytological examination of cervical cells remains important, particularly in the triage of HPV positive women. The interest of other biological techniques, such as HPV genotyping, viral load, cellular expression of p16/Ki-67 proteins and the methylation of cellular or viral genes, still needs to be clarified, but they could help to refine the triage strategy of HPV-positive women and limit the need for colposcopy and unnecessary stress for patients.

RESUMO

Simple and standardized approaches for genome analysis of human papillomavirus (HPV) by next-generation sequencing are needed. The aim of the study was to develop a protocol for direct deep sequencing of high-risk (hr) HPV strains, based on the widely used commercial Hybrid Capture 2 (QIAGEN) test, without any additional probe design. This protocol was applied to 15 HPV-positive and two HPV-negative cervical samples or cell lines and validated at the genotype level by comparing the sequencing results to those obtained using a commercial genotyping kit. The performance of our protocol, presented in this proof-of-principle study, supports its use for accurate characterization of genetic variants of hrHPV.

RESUMO

BACKGROUND: There is scarce data available about epidermal growth factor receptor (EGFR) mutations other than common exon 19 deletions and exon 21 (L858R) mutations. PATIENTS AND METHODS: EGFR exon 18 and/or exon 20 mutations were collected from 10 117 non-small-cell lung cancer (NSCLC) samples analysed at 15 French National Cancer Institute (INCa)-platforms of the ERMETIC-IFCT network. RESULTS: Between 2008 and 2011, 1047 (10%) samples were EGFR-mutated, 102 (10%) with rare mutations: 41 (4%) in exon 18, 49 (5%) in exon 20, and 12 (1%) with other EGFR mutations. Exon 20 mutations were related to never-smoker status, when compared with exon 18 mutations (P < 0.001). Median overall survival (OS) of metastatic disease was 21 months [95% confidence interval (CI) 12-24], worse in smokers than in non-smoker patients with exon 20 mutations (12 versus 21 months; hazard ratio [HR] for death 0.27, 95% CI 0.08-0.87, P = 0.03). Under EGFR-tyrosine kinase inhibitors (TKIs), median OS was 14 months (95% CI 6-21); disease control rate was better for complex mutations (6 of 7, 86%) than for single mutations (16 of 40, 40%) (P = 0.03). CONCLUSIONS: Rare EGFR-mutated NSCLCs are heterogeneous, with resistance of distal exon 20 insertions and better sensitivity of exon 18 or complex mutations to EGFR-TKIs, probably requiring individual assessment.

RESUMO

OBJECTIVES: High risk human papilloma-viruses (HR HPV) are associated with risk of cervical dysplasia and carcinoma. The risk is increased in patients with immune deficiency or auto-immune disease as systemic lupus erythematosus. Currently, no data are available about the human papillomavirus status in women with systemic sclerosis (SSc). METHODS: Thirty-one women with SSc were evaluated for cervical HPV infection and dysplasia, and compared to fifty age-matched control. Cervical swabs were tested by the INNO-LiPA assay®. Serum antibodies against HPV 16 and 18 were assessed using enzyme-linked immunosorbent assay in the SSc group. RESULTS: The overall HPV frequency was comparable between SSc and controls (32% vs. 38%), as well as the HR HPV frequency (28% vs. 34%), but infection by ≥2 HPV was two times more frequent in the SSc group (50% vs. 26% of the HPV positive samples). The most prevalent genotype was 52 in the SSc group (12%), and 52/53 in the control group (8% for both). Pap smears were within the normal range. Seropositivity for HPV 16 and 18 was 13% and 6.5%, respectively. A diffuse systemic sclerosis and a younger age at first intercourse were more frequent in cases of overall HPV positivity. Current smoking and a higher number of sexual partners were only observed in cases of seropositivity. CONCLUSIONS: This is the first study to evaluate HPV status in women with SSc. HR HPV52 was the most common genotype with a greater multi-HPV infection rate. This result needs to be confirmed in a larger study.

RESUMO

BACKGROUND: Tumour necrosis factor alpha (TNF-α) inhibitors are associated with an increased risk of infections and with a still debatable risk of skin cancer. Furthermore, cutaneous human papillomavirus (HPV) infection may be involved in skin cancer. OBJECTIVES: Our primary objective was to assess the HPV DNA prevalence in psoriasis patients treated with TNF inhibitors and the secondary objective was to assess the same parameter before and during treatment. METHODS: Plucked eyebrow hairs were collected from 151 consecutive patients with moderate to severe chronic plaque psoriasis, including 48 patients treated with anti-TNF-α agents, 21 patients treated with methotrexate (MTX) and 82 patients with no previous systemic treatment. Among them, 38 patients were subsequently treated with either MTX or anti-TNF-α agents. HPV genotyping was performed using the HPV type-specific E7 PCR bead-based multiplex allowing the detection of 27 genus-α types, 25 genus-ß types, 16 genus-γ types and one single genus-µ type. Follow-up provided a total of 972.7 person-months of overall exposure for patients treated with TNF inhibitors and 326.9 person-months for patients treated with MTX. RESULTS: Our data confirm the high prevalence of ß-HPV infection in healthy skin of psoriasis patients (68.9%), with no significant difference between untreated patients (64.6%), patients treated with MTX (76.2%) and patients treated with anti-TNF-α agents (72.9%). The mean number of different HPV types and the distribution of HPV types were similar in different groups of patients. Moreover, in prospectively treated patients, we did not observe any change in the HPV DNA prevalence in the distribution of HPV types and the number of HPV types after a mean duration of treatment of 332 ± 39.8 days. CONCLUSION: Despite the small number of patients in our cohort, our results are quite encouraging in view of the increased use of anti-TNF-α agents in different auto inflammatory immune diseases.

RESUMO

BACKGROUND: Episodes of CMV-viruria have been reported in hematopoietic stem cell transplant (HSCT) recipients, but their context of occurrence, pathophysiology, and clinical significance remain misunderstood. METHODS: Uurine samples from 517 recipients were collected. Clinical features of recipients with or without episodes of CMV-viruria were retrospectively compared. RESULTS: CMV-viruria was detected in 15.5 % of cases. Age, sex, type of transplantation, HLA-matching, conditioning regimen, and immunosuppressive therapies did not differ between patients with and without CMV-viruria. CMV-seropositive status (R + ) was more frequent among CMV-viruric recipients. Cumulated mortality did not differ between the two groups but graft-versus-host diseases occurred more frequently among CMV-viruric patients (p = 0.04). No reduction of the estimated glomerular filtration rates was observed in CMV-viruric recipients. CONCLUSIONS: CMV-viruria primarily occurs in CMV-seropositive recipients and is not related to the degree of immunosuppression. We suggest that CMV-viruria is primarily related to the inability of the graft immune system to contain CMV-replication in R + patients. CMV-viruria is not associated with increased mortality or renal dysfunction.

RESUMO

The performance of an in-house protocol for virus detection on commercialized electrostatic wipes (EWs) was assessed experimentally by impregnating them with suspensions of cytomegalovirus, adenovirus, and influenza virus, and by determining the recovery efficiency, repeatability, and detection limit of the protocol. The protocol was sensitive enough to detect 4 log10 gene copies of virus. At room temperature, influenza RNA was stable on EWs for at least four days. When EWs were placed high in 32 influenza-infected patients' rooms, influenza RNA was detectable in 75% (N = 24) of EWs, suggesting that EWs are simple and reliable methods for influenza virus airborne detection.

RESUMO

OBJECTIVE: To assess the expected impact in France of a quadrivalent HPV 6/11/16/18 vaccine on the occurrence of genital HPV-induced lesions in women. METHODS: A Markov model based on a quadrivalent vaccination of 14-year-old girls as recommended in France was performed to assess the number of subjects needed to vaccinate to prevent an HPV-related event during their lifetime and the expected annual number of cases which could be prevented by vaccination. This model was based on prevalence data reported in four large French studies (EDiTH I-IV) reporting an HPV 6/11/16/18 prevalence of 82% (95% CI: 78.5-85.1) in cervical cancer (CC), 64% (95% CI: 59.7-68.1) in CIN2/3, 34% (95% CI: 28.9-38.1) in low-grade squamous intraepithelial lesions (LSIL) and 83% (95% CI 77.6-87.8) in female external acuminata condylomata (EAC) cases. RESULTS: Using a theoretical vaccine efficacy of 100%, 130 young women need to be vaccinated to prevent a case of CC, 17 for a case of CIN2/3 and 13 for a case of EAC. Immunization of 80% of 14-year-old girls could prevent 2495 CC (72%), 17,985 CIN2/3 (54%), 8004 CIN1 (27%), and 22,531 EAC female cases (65%) in France annually. CONCLUSION: A good adhesion to the preferentially recommended HPV quadrivalent vaccination would thus substantially reduce the burden of female genital lesions in France.

RESUMO

OBJECTIVES: To evaluate the value of high-risk HPV (HR HPV) testing in screening and post-treatment follow-up of high-grade squamous intraepithelial cervical lesions (HSIL). METHODS: A systematic review of the literature from 2000 to 2019 was conducted including the following keywords: "human papilloma virus", "HPV testing", "cervical squamous intraepithelial lesion", "cervical cancer". RESULT: Numerous recent randomized studies and meta-analyzes have concordant results in favor of HR HPV superiority over cervical smear in the screening and post-treatment monitoring of HSIL. In screening, the sensitivity of the HR HPV tests is 63% to 98% whereas that of the cervical smear is only 38% to 65% for the detection of HSIL+ (HSIL and invasive cancers). A negative HR HPV test is associated with less than 5% risk of LIEHG+at 6 years. In addition, after removal of a LIEHG, HR HPV tests have a sensitivity>90% and specificity>80% to predict treatment failure. After surgicale exision, a negative HR HPV test is associated with a risk of failure<2% (negative predictive value of 98%), and 12-25% if it is positive. CONCLUSIONS: HR HPV tests are effective, allowing early detection of LIEHG+ identification of low-risk women in case of negative test, and a prediction of the risk of failure after treatment.

RESUMO

The study was aimed to evaluate the feasibility of detecting human papillomavirus (HPV) in women with normal or abnormal cervical smears using the Roche Amplicor MWP HPV Test. We compared by AMPLICOR Test and Hybrid Capture II (HCII) Test, the prevalence of HR-HPV in 470 cervical samples including 55 samples with WNL cytology, 208 ASC-US, 193 LGSIL and 14 HGSIL. Samples with discordant results were retested with INNO-LiPA Genotyping HPV Test v2. The HR-HPV positivity in WNL cytology samples was similar (21.8%) by AMPLICOR and HCII. In ASC-US, the HPV positivity was 42.3% by both tests. In LGSIL, HPV positivity was 66.3% and 66.8% by AMPLICOR and HCII, respectively. In HGSIL, 92.8% of samples were positive by AMPLICOR and 85.7% by HCII. The agreement of both tests was 96.2% with a Kappa value of 0.92. Eighteen cases were discordant: 9 HCII positive/AMPLICOR negative and 9 HCII negative/AMPLICOR positive. The INNO-LiPA test revealed HPV positivity in every case. Interestingly, all HCII+/AMPLICOR- samples were found to harbour HPV53. As for the HCII-/AMPLICOR+ samples, 8 demonstrated a multiple infection with HR 16- and/or 18- and/or 56-phylogenetically related HPV types. Moreover, two of these samples were co-infected with HPV6 and two other with HPV54. By using consensus HR-HPV as our reference HPV positivity, the sensitivity (96.6%) and specificity (100%) of AMPLICOR was similar to that of HCII Test. The AMPLICOR HPV Test is sensitive, specific, feasible and appropriate for routine HPV detection.

RESUMO

Cervical cancer, the second most common cancer in young women in France, is still today imperfectly screened even with the advent of primary prevention for this cancer in the form of prophylactic HPV vaccination. Indeed, the cervical Pap smear and its cytologic analysis, both operator and reader dependent, have limited sensitivities requiring repeated samplings and above all, producing a high rate of falsely negative tests. Although most cancers occur in women who are either not or insufficiently screened, the problem with cervical smears is the fact that cancers are also often diagnosed in young women having follow-ups in accordance with professional guidelines. The absence of an organized screening in France results in an inadequate female population coverage. Nowadays, it is unanimously recognized that high-risk papillomaviruses (HR HPV) represent the only independent risk factor for cervical cancer and that there cannot be any disease without this virus. It is therefore this strong association between a viral agent and the cervical cancer which opened the door firstly, to the notion of prophylactic vaccination and secondly, to the integration of HR HPV testing in the screening for precancerous lesions. Molecular biological techniques based on the HR HPV genome detection within the female genital tract have shown a very high sensitivity without any inter and intraobserver variability and an excellent negative predictive value. Their integration in the primary screening for cervical cancer would improve the relevance of the latter and would suit the need for a wider population coverage and even for an organized screening thanks to the possibility for self-sampling. The specificity of these tests is inferior to that of the cervical smear, but the management of the falsely positive HPV tests has proved to be efficient by sorting residual cells obtained from liquid-based cytology. What is urgent in France is the need for an organized screening programme in order to improve population coverage and, this does not go against neither a vaccination promotion nor the integration of new technologies. Moreover, the last three randomized trials published in October 2007 have shown that it was quite safely possible to extend the time interval between two consecutive viral testing and thus improving the cost-effectiveness of cervical cancer screening. The aim of this work was to analyze publications on the subject in order to conclude, according to proof levels obtained by different studies, on its usefulness in the secondary prevention of cervical cancer.

RESUMO

INTRODUCTION: Cervical intraepithelial neoplasia (CIN) 2 and CIN3 lesions clearly represent precancerous states even if some of them would heal spontaneously. Management is based on surgical excision of part of the uterine cervix because such lesions can potentially progress into carcinomas. In most cases, this treatment leads to the cure of intraepithelial lesions. However, even after such an efficient treatment, theses patients are still at a higher risk of developing an invasive cervical cancer. That is why guidelines recommend a specific follow-up in order to screen for residual disease (incomplete excision) or for recurrences (after a complete excision). The actual problem in the follow-up strategy lies in the screening tools in use - cervical smears and colposcopy - whose sensitivities are low and hence, not quite sufficient when applied to a high risk population. These intraepithelial lesions are due to high risk human papillomaviruses (HPV) and there cannot be any lesion progression without HPV. Consequently, a viral testing would help in identifying a high risk subpopulation of women after cone loop cervical excision. MATERIAL AND METHODS: We studied, retrospectively, the contribution of HPV testing (Hybrid Capture 2((R))) in the follow-up after CIN2-3 treatment in 386 cone loop cervical excisions performed at a single centre during 80 months. RESULTS: Between three to six months follow-up after surgery, HPV remained present in 22.5% cases. The sensitivity of HPV testing in the screening for residual lesions or for recurrences was 100%, that of cervical smears cytology was 72%, whereas that of the pathological analysis of margins reached only 67%. The negative predictive value of a negative HPV detection associated with a normal cytology was 100%. DISCUSSION: Owing to its clinical relevance, HPV testing optimises postoperative follow-up and leads to the rapid and efficient selection of a subgroup, representing less than one upon three patients who are really at risk of an invasive lesion and to wholly reassure the others. Indeed, a negative HPV testing, associated with a normal cervical cytology, obtained after surgery correspond to a negative predictive value of almost 100% and this allows us to increase the time-interval between two screenings and to rapidly place the patient in a routine follow-up.

RESUMO

BACKGROUND: Despite the availability of safe and effective HPV vaccines in France, more than 80% of girls remain unvaccinated. SETTING: A regional university hospital referral center in France. OBJECTIVE: To estimate the overall prevalence and distribution of HPV in vaccinated, sexually active young French women who were screened for cervical cancer by cytology and HPV testing. METHODS: High-risk HPV (HR-HPV) prevalence, genotype-specific prevalence and extent of multiple infections were assessed in 125 cervical samples from females with available vaccine data using hc2 assay and INNO-LiPA assay. HPV status was analyzed in accordance with cytological data. RESULTS: In our series, mean age was 23 years, overall prevalence of HR-HPV was 52% and was correlated with the lesion grade. The diversity of HPV genotypes was broad. Single HR-HPV infections were identified in 11%, 21% and 47% of women with NILM, ASC-US/-H and LSIL respectively. Multiple infections with HR-HPV were detected in 28% of the specimens. Only 24.5% of women with NILM presented infections with 2 genotypes or more, vs 28% of women with ASC-US/-H and 35% of women with LSIL. The overall prevalence of genotypes covered by the quadrivalent vaccine was low (5.9%); with 4.2%, 0%, 0.8% and 0.8% for HPV 16, HPV 18, HPV 6 and HPV 11 respectively. CONCLUSION: Among HPV-vaccinated young women, HR-HPV are detected at a high rate, and an association with the grade of cytological abnormalities was observed. However, HPV 16 and 18, both targeted by the vaccines, are remarkably rare among young French women since program implementation.

RESUMO

BACKGROUND: High burden of high risk human papillomavirus (HR HPV) has been shown to be predictive for the development of high grade cervical lesions and invasive cancers. However, low viral load cannot inevitably exclude progression towards cervical diseases. Moreover, few studies addressed whether viral load could predict infection clearance. OBJECTIVES: We carried out a retrospective study to analyze the variations of HPV16 load over time as a predictive marker of clinical outcome. STUDY DESIGN: The population consisted of 38 women who were found HR HPV positive by HCII test at study entry. Among them, 13 had developed a CIN2/3 (cases) and 25 had a negative HCII test and a normal cytology (controls) at study exit. The HPV16 DNA loads were quantified in 132 longitudinal cervical samples using quantitative real-time PCR. RESULTS: At study entry, the median of HPV16 load was not statistically different between controls and cases. However, when using a cut-off value of 200 copies/10(3) cells, the rate of cumulative incidence of CIN2/3 at 18 months increased from 14% in women with a load200 copies/10(3) cells. The longitudinal analysis performed on follow-up samples showed that in cases the progression to CIN2/3 was linked to HPV16 burden increasing over time, whereas in controls a decrease of at least 1 log HPV16 DNA load was observed over>or=2 time points. CONCLUSIONS: These results show that kinetics of HPV load, rather than a single HPV detection, might be more reliable to estimate whether a HPV infection will progress or be cleared.

RESUMO

OBJECTIVES: To assess opinions, practices and difficulties of general practitioners (GP) of Besançon concerning human papillomavirus (HPV) vaccination. MATERIALS AND METHODS: A survey among the 140 GP of Besançon, France, was conducted in 2015. RESULTS: A percentage of 77.1 reported being favourable to HPV vaccination and 72.9% practices HPV vaccination. The 2 main concerns about HPV vaccination for GP are the fear of side effects (for 40.6% of GP) and the doubt on efficacy. According to GP, the hepatitis B vaccination controversy, the fear of side effects, the limited clinical efficacy experience and the lack of confidence in health authorities are concerns about HPV vaccination for 77.1%, 76%, 74% and 49% of patients, respectively. CONCLUSION: Courses for GP on HPV vaccination must be pursued and reinforced. A school-based program could be developed to facilitate communication between GP and patients to improve HPV vaccination coverage.

RESUMO

Prescription of an HPV test in practice will enable the clinician to optimize the monitoring and the management of patients, especially in the context of cervical cancer screening. Numerous HPV tests are available that present different analytical and clinical sensitivity and specificity. International recommendations on clinical performance of HPV tests used for cervical cancer screening have been published by a group of experts, and tests that meet these performance criteria should be used. Apart from the HPV detection kit, the whole circuit from sampling to report of the results must be considered. This implies that the pre-analytical (sampling, quality of sample collection medium, storage condition and sample transportation…) and post-analytical steps (quality of result reporting, providing expert advices…) are also standardized. For this purpose, medical-biology laboratories are subjected to a COFRAC certification, as defined by the international standard ISO 15189 providing quality criteria for any clinical laboratory test and HPV test in particular.

RESUMO

In the present study, we compare the sensitivity of CaSki and HeLa cells (HPV positive, wild-type p53) and C33A cells (HPV negative, mutated p53) to a protein kinase inhibitor, the staurosporine (ST). We show that ST can reversibly arrest the three cervical-derived cell lines, either in G1 or in G2/M. Beyond certain ST concentrations or/and over 24 h exposure, the cells underwent apoptosis. This process took place in G1 and G2/M for C33A and CaSki plus HeLa cell lines, respectively. By using an in vitro cell-free system, we demonstrated that cytoplasmic extracts from apoptotic cells were sufficient to induce hallmarks of programmed cell death on isolated nuclei. Moreover, we found that only G2/M cytoplasmic extracts from viable CaSki and HeLa cells supplemented with ST, triggered apoptosis while exclusively G1 cytoplasmic fractions from C33A cells were efficient. Our study describes a possible involvement of the HPV infection or/and p53 status in this different ST-induced apoptosis susceptibility.

RESUMO

The aim was to determine the relevance of human papillomavirus (HPV) testing in identifying high-grade cervical intraepithelial neoplasia or worse (CIN2/3+) in a hospital population (n=3574) characterised by a high rate of cytological abnormalities and high-risk HPV infections. According to the results of the initial Papanicolaou and HPV test, women were directly referred for colposcopy/biopsy or recalled for a control visit. Sensitivity and specificity were corrected for verification bias. HPV-testing sensitivity was 94.3%, higher than that of cytological testing at any cut-off point (65.1%-86.8%), while specificity was greater for cytology than for HPV testing (99.3% or 91.8% versus 83.4%). The combination of both tests allowed 100% sensitivity and negative predictive value. We conclude that HPV testing is a relevant tool for the detection of cervical disease. The best way of combining cytology and HPV detection in screening programmes should be evaluated in large-scale studies.
