RESUMO

INTRODUCTION: We assessed the impact of a nationwide screening programme to reduce the risk of anal cancer in a large cohort of high-risk patients with HIV. METHODS: From a large database from one referral centre, all high-risk patients with HIV (men who have sex with men, history of anal or genital warts, or previous cervix human papillomavirus-related lesions) who were eligible to enter the French anal cancer screening programme (2011-2020) were retrospectively included. Adherence to the screening programme was defined as no interval >18 months between two visits. Standardized management included perianal visualization and standard anoscopy with biopsies of macroscopic abnormalities. RESULTS: Overall, 700 patients with HIV were included (median follow-up 8.4 years [interquartile range 4.3-9.2] and 1491.6 patient-years), and 336 had one or more proctology visit. A total of 13 patients were diagnosed with anal squamous cell carcinomas. The risk of anal cancer was higher with anal intra-epithelial neoplasia grade 3 (AIN3; hazard ratio [HR] 44.5 [95% confidence interval {CI} 11.2-176.6], p < 0.001), AIN2 (HR 11.9 [95% CI 2.1-66.9], p = 0.005), or high-grade dysplasia (HR 23.4 [95% CI 7.9-69.1], p < 0.001) than with low-grade dysplasia or no lesion. Among the patients who were strictly adherent to the screening programme (4.6% [32/700]), we did not report any AIN or anal cancer, but we also did not observe any significant reduction in the risk of anal cancer (p = 0.51), AIN3 (p = 0.28), high-grade dysplasia (p = 0.19), or any AIN lesions (p = 0.10) compared with non-adherent patients. In contrast, screened patients were more likely to be diagnosed with anal warts (HR 3.71 [95% CI 2.14-6.42], p < 0.001). CONCLUSION: Macroscopic high-grade dysplasia lesions are associated with a higher risk of developing anal cancer. Despite finding no cases of cancer during the screening programme, we also did not demonstrate a clear benefit from our screening programme for the prevention of anal cancer in high-risk patients with HIV.

RESUMO

BACKGROUND: The most effective treatment for anal fistula is fistulotomy, but it involves a risk of anal incontinence. To reduce this morbidity, sphincter-sparing treatments have been developed, but their success in real life is often less than 50%. The aim is to determine the clinical healing rate 6 months after radiofrequency treatment. METHODS: We planned to evaluate 50 patients from three French proctology centres. Treatment efficacy was evaluated at 6 and 12 months by means of clinical and magnetic resonance imaging examination. We evaluated morbidity and healing prognostic factors. RESULTS: Fifty patients with a mean age of 51 years (22-82) were included. Eleven patients had a low trans-sphincteric fistula (LTS), 21 patients had a high trans-sphincteric fistula (HTS), eight had a complex fistula and nine had Crohn's disease fistula. After 6 months, 17 patients (34.7%) had a clinically healed fistula, including five (45.5%) with LTS fistula, seven (33.3%) with HTS fistula, one (12.5%) with complex fistula, four (44.4%) with Crohn's disease, with no significant difference between these fistula types (p: 0.142). At 12 months, the healing rate was identical. MRI in 15 out of 17 clinically healed patients showed a deep remission of 73.3% at 12 months. Energy power was associated with the success of the treatment. There was an 8.2% incidence of post-surgical complications with 4.1% being abscesses (one required surgical management). Postoperative pain was minor. No new cases or deterioration of continence have been shown. CONCLUSION: Radiofrequency is effective in 34.7% of the cases as an anal fistula treatment in this first prospective study, with low morbidity and no effect on continence. Clinical healing was deep (MRI) in three-quarters at 1 year. The increase in energy power during the procedure seems to be a key point to be analysed to optimise results.

RESUMO

Squamous Cell Carcinoma of the Anal canal (SCCA) is a rare disease associated with a Human Papillomavirus (HPV) infection in most cases, predominantly the HPV16 genotype. About 15% of SCCA are diagnosed in metastatic stage and some will relapse after initial chemoradiotherapy (CRT). Treatment of patients by Docetaxel, Cisplatin and 5-fluorouracil (DCF) has been recently shown to improve their complete remission and progression-free survival. The aim of this retrospective study was to explore the impact of HPV infection, HPV DNA integration, TERT promoter mutational status and somatic mutations of oncogenes on both progression-free (PFS) and overall survivals (OS) of patients treated by DCF. Samples obtained from 49 patients included in the Epitopes-HPV02 clinical trial, diagnosed with metastatic or non-resectable local recurrent SCCA treated by DCF, were used for analyses. Median PFS and OS were not associated with HPV status. Patients with episomal HPV had an improved PFS compared with SCCA patients with integrated HPV genome (p=0.07). TERT promoter mutations were rarely observed and did not specifically distribute in a subset of SCCA and did not impact DCF efficacy. Among the 42 genes investigated, few gene alterations were observed, and were in majority amplifications (68.4%), but none were significantly correlated to PFS. As no biomarker is significantly associated with patients' survival, it prompts us to include every patient failing CRT or with metastatic disease in DCF strategy.

RESUMO

BACKGROUND: Crohn's disease (CD) is complicated by perianal fistulas in approximately 20% of patients. Achieving permanent fistula closure remains a challenge for physicians. An association between serum anti-tumor necrosis factor-α concentrations and clinical outcomes in patients with CD has been demonstrated; however, little information is available on serum adalimumab (ADA) concentrations and remission of perianal fistulas in such patients. AIM: To study the relationship between serum ADA concentrations and clinical remission of CD-associated perianal fistulas. METHODS: This cross-sectional study of patients with CD-associated perianal fistulas treated with ADA was performed at four French hospitals between December 2013 and March 2018. At the time of each serum ADA concentration measurement, we collected information about the patients and their fistulas. The primary study endpoint was clinical remission of fistulas defined as the absence of drainage (in accordance with Present's criteria), with a PDAI ≤ 4, absence of a seton and assessment of the overall evaluation as favorable by the proctologist at the relevant center. We also assessed fistula healing [defined as being in clinical and radiological (magnetic resonance imaging, MRI) remission] and adverse events. RESULTS: The study cohort comprised 34 patients who underwent 56 evaluations (patients had between one and four evaluations). Fifteen patients had clinical remissions (44%), four of whom had healed fistulas on MRI. Serum ADA concentrations were significantly higher at evaluations in which clinical remission was identified than at evaluations in which it was not [14 (10-16) vs 10 (2-15) µg/mL, P = 0.01]. Serum ADA concentrations were comparable at the times of evaluation of patients with and without healed fistulas [11 (7-14) vs 10 (4-16) µg/mL, P = 0.69]. The adverse event rate did not differ between different serum ADA concentrations. CONCLUSION: We found a significant association between high serum ADA concentrations and clinical remission of CD-associated perianal fistulas.

RESUMO

AIM: In patients with fistulizing perianal Crohn's disease (CD), the need for a secondary surgical step is not defined. The aim was to assess the efficacy of surgical closure compared to a single seton removal in patients with drained fistulizing perianal CD treated with adalimumab. METHODS: This was a multicentre, randomized controlled trial, comparing seton removal + surgical closure (closure group) to seton removal alone (control group) with a stratification according to the American Gastroenterological Association classification. The primary end-point was fistula closure at month 12 defined by the association of the following criteria: no seton, absence of a visible external opening, absence of discharge from the tract after finger compression, absence of an internal opening, absence of perianal pain/abscess and absence of fistula-related abnormalities. RESULTS: Among the 64 included patients (262 expected) (48 complex fistula, 75%), 33 were randomized to the closure group and 31 to the control group. In the closure group, 26 patients (78.8%) had glue. At month 12, overall fistula closure was achieved in 35 of the evaluable 58 patients (60%): 18/32 (56%) in the surgery group and 17/26 (65%) in the control group (P = 0.479). In the closure group, fistula closure was observed in 13/25 (52%) and 5/7 (71%) patients with complex and simple fistula respectively (P = 0.426), compared with 12/18 (67%) and 5/8 (63%), respectively in the control group (P = 1.000). CONCLUSIONS: Seton removal alone seems to be no more effective than a secondary surgical step (in particular glue injection) in patients having fistulizing perianal CD controlled by an initial drainage combined with adalimumab. The results should be interpreted with caution.

RESUMO

INTRODUCTION: for localized T1N0 squamous cell carcinoma of the anus (SCCA) standard radiotherapy (RT) may result in overtreatment and alternative strategies are debated. METHODS: T1N0M0 SCCA treated between 2015 and 2020 by local excision (LE) or RT were analyzed from the French prospective FFCD ANABASE cohort. Treatment strategies, recurrence-free and colostomy-free survivals (RFS, CFS) and prognostic factors were reported. RESULTS: among 1135 SCCA patients, 99 T1N0M0 were treated by LE(n = 17,17.2%), or RT (n = 82,82.8%) including RT alone (n = 65,79.2%) or chemo-RT (n = 17, 20.7%). Median follow-up was 27.2 months [0.03-54.44]. Median tumor size were 11.4 mm [0.9-20] and 15.3 mm [2-20] in the LE and RT groups respectively. Mean RT tumor dose was 59.4 Gy [18-69.4 Gy]. One patient in LE group and 9 in RT group had a pelvic recurrence, either local (60%), nodal (10%) or both (30%). RFS and CFS at 24 months were 92.2%[95%CI,83.4-96.4] and 94.6%[95%CI,86.1-98.0], at 36 months 88.1%[95%CI,77.1-94.2] and 88.5%[95%CI,77.0-94.5], in LE and RT group respectively, without any significative difference (HR = 0.57;[95%CI,0.07-4.45];p = 0.60). By univariate analysis, male gender was the only prognostic factor(HR = 5.57;95%CI, 1.76-17.63; p = 0.004). CONCLUSION: this cohort confirms the heterogeneity of T1N0M0 SCCA management, questioning the place of RT alone, reduced dose or RT volume, and the safety of LE.

RESUMO

PURPOSE: Anal dysplasia is caused by chronic infection with the human papillomavirus and exposes to the risk of anal cancer. The aim of this study was to evaluate the distribution of dysplasia anal grade among patients operated on for multiple anal condylomas with no macroscopic differences. METHODS: This is a cross-sectional study of patients operated on for multiple anal condylomas including a mapping of dysplasia by performing systematically for each patient one biopsy on visible lesion from each of the 4 quadrants on anal margin and in anal canal. All biopsies were read independently by 2 different pathologists. RESULTS: Among 72 patients, 60 were men and 48 were human immunodeficiency virus (HIV)-infected with a median age of 37.5 years. The proportion of high-grade squamous intraepithelial lesion (HSIL) was higher in the anal canal (41.7%) compared to the margin (20.8%) (P = 0.004). HSIL frequency did not differ according to the quadrant (anterior, posterior, right, and left) of the 2 areas. HSIL on anal canal was not associated with HSIL on anal margin and vice versa (P = 0.390). Neither age nor sex was associated to HSIL but HIV positivity increased the risk of HSIL on the anal margin (P = 0.010). CONCLUSION: Anal dysplasia is heterogeneously distributed in the anal canal as well as between anal canal and anal margin. The diagnostic of the grade of dysplasia for a person should require multiple biopsies on the canal and anal margin.

RESUMO

AIM: The treatment of perianal fistulas in Crohn's disease remains challenging. Fibrin glue injection has previously shown short-term efficacy in a randomized controlled trial. No long-term data are available to assess the benefit of this treatment. METHODS: This retrospective multicentre study included all patients with drained fistulas treated by at least one fibrin glue injection between January 2004 and June 2015 in three tertiary French centres. The primary end-point was the rate of complete clinical remission at 1 year after injection defined by the closure of all fistula tracts with no need for iterative anal surgery or for optimization of immunosuppressants and/or biologics. RESULTS: In all, 119 patients (median age 33 years, complex fistulas 65%, median previous anal surgery two, median Harvey Bradshaw score 3, immunosuppressants exposure 50%, anti-tumor necrosis factor exposure 60% with median time of administration of 1.1 year) were analysed with a median follow-up of 18.3 months. The complete clinical remission rate at 1 year was 45.4%. The primary end-point was achieved in 63% of the cases in the combination therapy group and 37% in other patients. The only predictor of complete clinical remission at 1 year was combination therapy at the time of injection (P = 0.01). The rate of early reintervention after glue injection was 2.5%. The cumulative incidence of iterative anal surgery and ostomy in the whole population was 54% and 5.6% respectively at 5 years. CONCLUSION: An adjunct of fibrin glue to conventional medical therapy may be an effective and safe treatment for perianal fistulas in patients with Crohn's disease.

RESUMO

PURPOSE: Anal squamous cell carcinoma is associated with multiple risk factors, including infection with human papillomavirus and human immunodeficiency virus, immunosuppression, multiple sex partners, receptive anal sex and tobacco smoking. The aim of our study was to identify prognostic factors associated with poor outcomes after radiotherapy for anal cancer. METHODS: We analysed retrospectively the medical records of 171 patients treated by (chemo)radiotherapy for non-metastatic anal cancer in our institution from 2000 to 2015. Patients and tumour characteristics, treatments (chemotherapy, radiotherapy [RT] and surgery) and outcomes were reported. Colostomy-free survival (CRF), disease-free survival and overall survival (OS) at 5 years were studied. Univariate and multivariate analyses were performed by logistic regression to determine factors associated with poor progression-free survival (PFS). RESULTS: Patients' characteristics were as follows: median age, 62 years (range = 36-89); gender, 45 men (26%) and 126 women (74%); HIV serology, positive: 21 patients (12%); tobacco smoking, 86 patients (50%), among whom 28 patients and 58 patients were current and former smokers, respectively. Tumours were classified as locally limited (T1-2, N0, M0) for 86 patients (50%) and locally advanced (T3-4 or N+, M0) for 85 patients (50%). The median total dose was 64.4 Gy (range = 54-76.6), and 146 patients were treated by concurrent chemoradiotherapy. Factors associated with poor PFS in univariate analysis were as follows: tumour size >4 cm, lymph node involvement, tobacco smoking, no initial surgical excision and anal warts at diagnosis. In multivariate analysis, only tobacco smoking status was significantly associated with poor PFS (hazard ratio = 2.85, 95% confidence interval [1.25-6.50], p = 0.013). Five-year PFS for non-smokers, former smokers and current smokers was 88.1%, 76.7% and 73.8%, respectively (p = 0.038). Tobacco smoking was also associated with poor overall survival (p = 0.03), locoregional relapse-free survival (LRFS; p = 0.05) and CFS (p = 0.02). CONCLUSIONS: Tobacco smoking status is associated with poor OS, LRFS, PFS and CFS in patients treated for anal cancer by high RT dose ± chemotherapy.

RESUMO

INTRODUCTION: Studies have shown that the PD-1/PD-L1 immunomodulatory pathway slows down anti-tumor immunity in a number of cancers. The description of the expression of these molecules has never been performed in anal low-grade/high grade squamous intra-epithelial lesions (LSIL/HSIL respectively). MATERIALS AND METHODS: Patients followed in the AIN3 cohort were routinely sampled. For each selected sample, an immunohistochemical study was performed with anti-CD8, PD-1, PD-L1 antibodies. The presence and distribution of CD8+ lymphocytes, and the presence of PD-1+ lymphocytes and PD-L1+ epithelial cells were assessed. The comparison of these characteristics was performed between the HSIL and LSIL groups. RESULTS: 33 patients were included and 78 samples selected (60 HSIL and 18 LSIL). CD8+ lymphocytes were observed more frequently in HSIL versus LSIL in the lamina propria or intra epithelial (respectively 90% vs. 60%, p = 0.01; and 62% vs. 33%, p = 0.04). PD-1+ lymphocytes were observed more frequently in HSIL versus LSIL (41% vs 11%, p = 0.03). There was no difference between HSIL and LSIL for PD-L1+ epithelial cells. CONCLUSIONS: Anal dysplastic lesions are accompanied by an inflammatory lymphocytic infiltrate expressing CD8 and PD-1, more frequent in high-grade lesions. These results highlight the involvement of the PD-1/PD-L1 pathway in the natural history of anal dysplasia.

RESUMO

Human papillomaviruses (HPV) infection is now known to be responsible for almost all cervical cancers, and for a substantial fraction of Head and Neck cancers (HNCs). However, comprehensive epidemiological and economic data is lacking in France, especially for rarer potentially HPV-related cancers, which include anal, vulvar and vaginal cancers. Using the national comprehensive database of French public and private hospital information (PMSI), we assessed prevalence and incidence of patients with in-hospital diagnosis for potentially HPV-related cancers in 2013, and estimated costs related to their management over a 3-year period after diagnosis in France. Concerning female genital cancers, 7,597, 1,491 and 748 women were hospitalized for cervical, vulvar and vaginal cancer in 2013, respectively, with 3,120, 522 and 323 of them being new cases. A total of 4,153 patients were hospitalized for anal cancer in 2013, including 1,661 new cases. For HNCs, 8,794 and 14,730 patients were hospitalized for oral and oropharyngeal cancer in 2013, respectively; 3,619 and 6,808 were new cases. Within the 3 years after cancer diagnosis, the average cost of hospital care per patient varied from €28 K for anal cancer to €41 K for oral cancer. Most expenditures were related to hospital care, before outpatient care and disability allowance; they were concentrated in the first year of care. The total economic burden associated with HPV-potentially related cancers was about €511 M for the French National Health Insurance over a 3 years period (2011 to 2013), ranging from €8 M for vaginal cancer to €222 M for oropharyngeal cancer. This study reported the most up-to-date epidemiological and economic data on potentially HPV-related cancers in France. These results may be used to evaluate the potential impact of new preventive strategies, namely the generalized organized screening of cervical cancer and the nine-valent HPV vaccine, indicated in the prevention of cervical, vaginal, vulvar and anal cancers.

RESUMO

Background: The aim of this study was to investigate the presence of minority variants (MVs) in high-risk human papillomavirus (HPV) types (HPV-16, -52, and -58) from cervical and anal smears. Methods: Whole HPV genome ultra-deep sequencing (UDS) was performed on cervical and anal smears collected during patient follow-up. Bioinformatics analyses were performed using Bowtie2 (Geneious). Results: We assessed 55 HPV-16-positive, 20 HPV-52-positive, and 17 HPV-58-positive samples, with significant differences in patient characteristics for the 2 anatomic sites. HPV-16 MVs were detected in 20 samples (36%), with no difference between cervical and anal samples. We did not find an association between the presence of MVs and cytovirological parameters. Seven HPV-16 genomes (13%) were apolipoprotein B messenger RNA editing, catalytic polypeptide-like 3 (APOBEC) edited. Among the cervical HPV-16-positive samples, most MVs (55%) resulted from APOBEC-related mutations. MVs were detected in 10 HPV-52-positive (50%) and 12 HPV-58-positive (71%) samples, with no difference between cervical and anal samples. No APOBEC-related mutations were found on HPV-58 or HPV-52 genomes. Conclusions: Overall, high-risk HPV MVs were found in about half of all cases in both anal and cervical samples. Interestingly, we reported for the first time a differential impact of APOBEC3 mutagenic activity depending on high-risk HPV type.

RESUMO

AIM: To establish consensual definitions of anoperineal lesions of Crohn's (APLOC) disease and assess interobserver agreement on their diagnosis between experts. METHODS: A database of digitally recorded pictures of APLOC was examined by a coordinating group who selected two series of 20 pictures illustrating the various aspects of APLOC. A reading group comprised: eight experts from the Société Nationale Française de Colo Proctologie group of study and research in proctology and one academic dermatologist. All members of the coordinating and reading groups participated in dedicated meetings. The coordinating group initially conducted a literature review to analyse verbatim descriptions used to evaluate APLOC. The study included two phases: establishment of consensual definitions using a formal consensus method and later assessment of interobserver agreement on the diagnosis of APLOC using photos of APLOC, a standardised questionnaire and Fleiss's kappa test or descriptive statistics. RESULTS: Terms used in literature to evaluate visible APLOC did not include precise definitions or reference to definitions. Most of the expert reports on the first set of photos agreed with the main diagnosis but their verbatim reporting contained substantial variation. The definitions of ulceration (entity, depth, extension), anal skin tags (entity, inflammatory activity, ulcerated aspect), fistula (complexity, quality of drainage, inflammatory activity of external openings), perianal skin lesions (abscess, papules, edema, erythema) and anoperineal scars were validated. For fistulae, they decided to follow the American Gastroenterology Association's guidelines definitions. The diagnosis of ulceration (κ = 0.70), fistulae (κ = 0.75), inflammatory activity of external fistula openings (86.6% agreement), abscesses (84.6% agreement) and erythema (100% agreement) achieved a substantial degree of interobserver reproducibility. CONCLUSION: This study constructed consensual definitions of APLOC and their characteristics and showed that experts have a fair level of interobserver agreement when using most of the definitions.

RESUMO

INTRODUCTION: This document is a summary of the French Intergroup guidelines regarding the management of anal carcinomas, published in November 2016. METHODS: It is a collaborative work produced under the auspices of the majority of the French medical societies involved in the management of anal cancer. It is based on the previous guidelines published in 2010. Recommendations are graded in three categories, according to the amount of evidence found in the literature. RESULTS: Non-metastatic anal carcinomas can be divided into two risk groups, according to magnetic resonance imaging (MRI) or endorectal-ultrasonograpy. Localized small cancers (T1N0) are mainly treated by exclusive radiation therapy in the case of cancers of the anal canal, or by surgery in the case of cancers of the anal margin. The recommended treatment of locally advanced tumours (T2-T4, N0-N2) is definitive concomitant radio-chemotherapy. Salvage surgery should be reserved for patients with poor response, tumour progression or local relapse after radio-chemotherapy, or in cases of persistent vaginal fistula or total anal incontinence after the cessation of radio-chemotherapy. In the case of metastatic tumours, current therapeutic recommendations are based on less robust evidence; with chemotherapy playing a major role. CONCLUSION: These recommendations are permanently being reviewed, and each individual case must be discussed inside a multidisciplinary team.

RESUMO

Patients with inflammatory bowel disease [IBD] may develop, similarly to individuals from general population, rare cases of human papilloma virus [HPV]-related anal canal squamous cell carcinoma [SCC] and intra-epithelial precursor lesions, as well as very rare cases of anal canal adenocarcinoma. Patients with chronic perianal Crohn's disease [CD] are at substantial risk of developing SCC or adenocarcinoma from the fistula-lining epithelium, as well as SCC or adenocarcinoma arising from chronic anorectal ulcerations or strictures. Based on this lesion stratification, we provide in this review tailored incidence estimates and we propose an IBD-specific classification of all types of anal neoplasia that may occur in patients with IBD. After reviewing putative carcinogenesis of all types of neoplasia, we conclude that HPV vaccination could reduce the incidence of HPV-related lesions, although an anal screening programme related to these lesions is not mandatory on the sole basis of IBD. By contrast, we point out that all patients with chronic perianal CD should be explored in depth, including biopsies under anaesthesia and fistula curettage when necessary, in case of any change in anal symptoms ─in particular new, increasing, unexplained pain. Finally, we conclude that there is an urgent need for elaborating and evaluating surveillance algorithms in patients with chronic perianal CD, in order to avoid cancers with late diagnosis and poor prognosis.

RESUMO

Background: In 2006, the HPV (Human papillomavirus) 6/11/16/18 quadrivalent vaccine was approved by the European Medicines Agency and obtained its marketing authorization in both girls and boys. Currently, the French guidelines recommend and refund vaccination of girls aged 11 to 14 with a catch-up program for females from 15 to 19 years old. Discussion: In France, HPV vaccination coverage tends to decrease. At the end of 2015, the vaccination coverage with three doses reached only 14% in 16-year-old girls (three doses). Although men are also affected by HPV-related diseases such as anal cancer, ano-genital warts, penile cancer or upper aerodigestive tract cancer, vaccine recommendations in France are for girls only. To face the high prevalence of anal cancer and related diseases, the best option is vaccination. Moreover, by offering men a way to prevent diseases against which they do not have any protection yet, universal vaccination could better take into account the ethical issues of prevention. In this paper, we present the point of view of different medical specialties concerning the potential benefit of extending vaccination to boys. Conclusion: HPV vaccination of both genders could benefit from a better public acceptance and contribute to a better coverage, especially in countries with low vaccination rates.

RESUMO

Despite effective highly active antiretroviral treatment, anal cancer incidence has recently strongly increased in HIV-infected population. Treatment strategy in HIV-infected patients does not differ from general population. HIV-infected patients treated by chemo-radiotherapy are exposed to high-grade toxicities and should be closely monitored to deliver the optimal treatment. Close collaboration between oncologist and infectiologist is highly recommended to adjust antiretroviral therapy if necessary.

RESUMO

BACKGROUND: Data on the current management of inflammatory bowel disease are scarce. METHODS: This was a nationwide survey among 65 private gastroenterologists treating patients with inflammatory bowel disease in France in 2012. RESULTS: A total of 375 inflammatory bowel disease patients were analysed: 48% had ulcerative colitis. One third of inflammatory bowel disease patients had a history of hospitalisation, and 40% of Crohn's disease patients had prior surgery. Two thirds of inflammatory bowel disease patients had active disease. Significantly fewer ulcerative colitis patients were treated with anti-tumour necrosis factor therapy than Crohn's disease patients (18.9% vs. 38.9%; p<0.0001). Among patients treated with anti-tumour necrosis factor, only 4.5% were receiving concomitant immunomodulators. Half of inflammatory bowel disease patients had undergone a colonoscopy within the past year. For colorectal cancer screening, random biopsies and chromoendoscopy were performed in 75% and 40% of cases, respectively. An endoscopic score was used for only 10% of inflammatory bowel disease patients. About one third of inflammatory bowel disease patients had imaging studies within the past year (magnetic resonance enterography in 65%). An abdominal computed tomography scan was prescribed for 12% of inflammatory bowel disease patients. CONCLUSIONS: Many patients still have active disease in the biologics era, and the number of patients receiving combination therapy is low in private practice. Chromoendoscopy and endoscopy scores are not often used.

RESUMO

PURPOSE: To study recent trends in the incidence of anal cancer in HIV-infected patients receiving long-term combined antiretroviral treatment (cART) compared with the general population. PATIENTS AND METHODS: From the French Hospital Database on HIV, we identified 263 cases of invasive anal squamous cell carcinoma confirmed histologically between 1992 and 2008. We compared incidence rates of anal cancer across four calendar periods: 1992-1996 (pre-cART period), 1997-2000 (early cART period), and 2001-2004 and 2005-2008 (recent cART periods). Standardized incidence ratios (SIRs) were calculated by using general population incidence data from the French Network of Cancer Registries. RESULTS: In HIV-infected patients, the hazard ratio (HR) in the cART periods versus the pre-cART period was 2.5 (95% CI, 1.28 to 4.98). No difference was observed across the cART calendar periods (HR, 0.9; 95% CI, 0.6 to 1.3). In 2005-2008, HIV-infected patients compared with the general population had an excess risk of anal cancer, with SIRs of 109.8 (95% CI, 84.6 to 140.3), 49.2 (95% CI, 33.2 to 70.3), and 13.1 (95% CI, 6.8 to 22.8) for men who have sex with men (MSM), other men, and women, respectively. Among patients with CD4 cell counts above 500/µL for at least 2 years, SIRs were 67.5 (95% CI, 41.2 to 104.3) when the CD4 nadir was less than 200/µL for more than 2 years and 24.5 (95% CI, 17.1 to 34.1) when the CD4 nadir was more than 200/µL. CONCLUSION: Relative to that in the general population, the risk of anal cancer in HIV-infected patients is still extremely high, even in patients with high current CD4 cell counts. cART appears to have no preventive effect on anal cancer, particularly in MSM.
