RESUMO

Men who have sex with men living with HIV (MSM LWH) are at highest risk for human papillomavirus (HPV)-associated anal cancer. There is no consensus on the optimal screening initiation age. This study aimed to assess the prevalence and severity of anal HPV disease among MSM LWH under the age of 35, which is a currently proposed screening age threshold. Between 2014 and 2020, 1255 18-to-34-year-old MSM LWH underwent anal cytology screening. 916 were co-tested for high-risk HPV (HR-HPV). 467 underwent high-resolution anoscopy (HRA) and biopsy. Cancer registry data were queried. Predictors of abnormal cytology (ie, ≥ASCUS) and histological high-grade squamous intraepithelial lesions (HSIL) were evaluated using unadjusted logistic regression models. Median age was 28 years (range, 18-34). 19% received at least one dose of HPV vaccine. Abnormal cytology rate was 65%. HR-HPV and HPV16 prevalence were 87% and 30%. Biopsy results were benign (10%), LSIL (43%) and HSIL (47%). No cases of prevalent or incident anal cancers were detected. Findings were similar between age subgroups (18-24, 25-29 and 30-34) except for a higher prevalence of AIN 3 in the 30-34 group (19%). Abnormal cytology was significantly associated with HR-HPV infection. Histological HSIL was associated with HR-HPV infection and cytological LSIL or worse. The absence of anal cancer in a large cohort of MSM LWH under the age of 35, despite high prevalence of anal HR-HPV infection and precancer, supports an age-based anal cancer screening strategy for MSM LWH.

RESUMO

An estimated 38 million people live with human immunodeficiency virus (HIV) worldwide and are at excess risk for multiple cancer types. Elevated cancer risks in people living with HIV (PLWH) are driven primarily by increased exposure to carcinogens, most notably oncogenic viruses acquired through shared transmission routes, plus acceleration of viral carcinogenesis by HIV-related immunosuppression. In the era of widespread antiretroviral therapy (ART), life expectancy of PLWH has increased, with cancer now a leading cause of co-morbidity and death. Furthermore, the types of cancers occurring among PLWH are shifting over time and vary in their relative burden in different parts of the world. In this context, the International Agency for Research on Cancer (IARC) and the US National Cancer Institute (NCI) convened a meeting in September 2022 of multinational and multidisciplinary experts to focus on cancer in PLWH. This report summarizes the proceedings, including a review of the state of the science of cancer descriptive epidemiology, etiology, molecular tumor characterization, primary and secondary prevention, treatment disparities and survival in PLWH around the world. A consensus of key research priorities and recommendations in these domains is also presented.

RESUMO

BACKGROUND: Women with human immunodeficiency virus (WWH) have an elevated risk for human papillomavirus (HPV)-associated anal cancer. Primary anal cancer screening results from this population could inform practice guidelines. METHODS: In total, 381 WWH with anal cytology screening, high-risk HPV (hrHPV) testing and genital (cervical or vaginal) cotesting within 6 months were identified during 2012-2019. Those with anal cytology of atypical squamous cells of undetermined significance (ASCUS) or worse underwent high-resolution anoscopy and biopsy. Independent predictors of anal hrHPV, HPV16, and histological anal high-grade squamous intraepithelial lesions (aHSIL) were identified using adjusted logistic regression models. RESULTS: Prevalence of anal hrHPV, HPV16, and ASCUS or worse cytology was 61%, 13%, and 68%. Histological aHSIL was detected in 42% of WWH with ASCUS or worse anal cytology. Prevalence of genital hrHPV, HPV16, and ASCUS or worse cytology was 30%, 4%, and 28%. Genital hrHPV predicted anal hrHPV (odds ratio [OR], 5.05), while genital HPV16 predicted anal HPV16 (OR, 9.52). Genital hrHPV and anal HPV16 predicted histological aHSIL (ORs, 2.78 and 10.9). CONCLUSIONS: Anal HPV disease was highly prevalent in this primary screening cohort of WWH. While genital screening results predicted anal disease, rates of isolated anal HPV disease were substantial, supporting universal anal cancer screening for this population.

RESUMO

BACKGROUND: Methods for screening agents earlier in development and strategies for conducting smaller randomized controlled trials (RCTs) are needed. METHODS: We retrospectively applied a tumor growth model to estimate the rates of growth of pancreatic cancer using radiographic tumor measurements or serum CA 19-9 values from 3033 patients with stages III-IV PDAC who were enrolled in 8 clinical trials or were included in 2 large real-world data sets. RESULTS: g correlated inversely with OS and was consistently lower in the experimental arms than in the control arms of RCTs. At the individual patient level, g was significantly faster for lesions metastatic to the liver relative to those localized to the pancreas. Regardless of regimen, g increased toward the end of therapy, often by over 3-fold. CONCLUSIONS: Growth rates of PDAC can be determined using radiographic tumor measurement and CA 19-9 values. g is inversely associated with OS and can differentiate therapies within the same trial and across trials. g can also be used to characterize changes in the behavior of an individual's PDAC, such as differences in the growth rate of lesions based on metastatic site, and the emergence of chemoresistance. We provide examples of how g can be used to benchmark phase II and III clinical data to a virtual reference arm to inform go/no go decisions and consider novel trial designs to optimize and accelerate drug development.

RESUMO

Nonalcoholic fatty liver disease (NAFLD) affects an estimated 17% of pregnant patients in the USA. However, there are limited data on the impact of maternal NAFLD on pediatric outcomes. We prospectively evaluated outcomes in infants born to mothers with and without NAFLD in pregnancy over their first 2 years of life. Maternal subjects were identified through an ongoing prospective study in which pregnant individuals were screened for NAFLD. Pediatric outcomes of infants born to these mothers-including adverse neonatal outcomes and weight and weight-for-length percentile at 6, 12, 18, and 24 months-were prospectively evaluated. Multivariate logistic regression was performed to evaluate the association of maternal NAFLD with pediatric outcomes, as well as to adjust for potentially confounding maternal characteristics. Six hundred thirty-eight infants were included in our cohort. The primary outcomes assessed were weight and growth throughout the first 2 years of life. Maternal NAFLD was also not associated with increased infant birth weight or weight-for-gestational-age percentile or weight or weight-for-length percentile over the first 2 years of life. Maternal NAFLD was significantly associated with very premature delivery before 32 weeks, even after adjustment for confounding maternal characteristics (aOR = 2.83, p = 0.05). Maternal NAFLD was also significantly associated with neonatal jaundice, including after adjusting for maternal race (aOR = 1.67, p = 0.03). However, maternal NAFLD was not significantly associated with any other adverse neonatal outcomes.    Conclusion: Maternal NAFLD may be independently associated with very premature birth and neonatal jaundice but was not associated with other adverse neonatal outcomes. Maternal NAFLD was also not associated with any differences in infant growth over the first 2 years of life. What is Known: • Maternal NAFLD in pregnancy may be associated with adverse pregnancy and neonatal outcomes, but the findings are inconsistent across the literature. What is New: • Maternal NAFLD is not associated with any differences in weight at birth or growth over the first 2 years of life. • Maternal NAFLD is associated with very premature delivery and neonatal jaundice, but is not associated with other adverse neonatal outcomes.

RESUMO

PURPOSE: The risk of prostate cancer among persons living with human immunodeficiency virus (PWH) is not well understood and may be obscured by different opportunities for detection. MATERIALS AND METHODS: We identified 123,472 (37,819 PWH and 85,653 comparators) men enrolled in the Veterans Aging Cohort Study, a prospective national cohort of PWH and demographically matched, uninfected comparators in 2000-2015. We calculated rates of prostate specific antigen (PSA) testing by human immunodeficiency virus (HIV) status and fit multivariable Poisson models comparing the rates of PSA testing, prostate biopsy, and cancer incidence. RESULTS: The mean age at enrollment was 52 years. Rates of PSA testing were lower in PWH versus uninfected comparators (0.58 versus 0.63 tests per person-year). Adjusted rates of PSA screening and prostate biopsy were lower among PWH (incidence rate ratio [IRR] 0.87, 95% CI 0.75-0.84 and IRR 0.79 95% CI 0.74-0.83, respectively). The crude IRR for prostate cancer was lower in PWH versus controls (IRR 0.90, 95% CI 0.83-0.97). However, in a multivariable model adjusting for PSA testing, cancer incidence was similar by HIV status (IRR=0.93, 95% CI 0.86-1.01, p=0.08). Among patients who received a prostate biopsy, incidence of prostate cancer did not differ significantly by HIV status (IRR 1.06, 95% CI 0.98-1.15, p=0.15). Among incident cancers, there were significant differences in the distributions of Gleason grade (p=0.05), but not cancer stage (p=0.14) by HIV status. CONCLUSIONS: When accounting for less PSA testing among PWH, the incidence of prostate cancer was similar by HIV status. These findings suggest that less screening contributed to lower observed incidence of prostate cancer in PWH.

RESUMO

BACKGROUND: Screening strategies for high-risk human papillomavirus (hrHPV)-associated anal cancer are evolving. Herein, we compare anal cytology to hrHPV DNA testing and 2 novel cytology/hrHPV cotesting algorithms among 3 high-risk populations. METHODS: Anal cytology, hrHPV DNA testing, and high-resolution anoscopy (HRA)-guided biopsy results were analyzed from 1837 participants (1504 HIV-infected men who have sex with men (MSM), 155 HIV-uninfected MSM, and 178 HIV-infected women). Performance to detect histological high-grade squamous intraepithelial lesions (HSIL)/cancer was compared between 4 strategies with distinct HRA referral thresholds: cytology (atypical squamous cells of undetermined significance, ASCUS); hrHPV testing (any hrHPV positive); algorithm A (benign cytology/HPV16/18 positive or ASCUS/hrHPV positive); and algorithm B (benign or ASCUS/hrHPV positive). RESULTS: Histological HSIL/cancer was detected in 756 (41%) participants. Cytology had the lowest sensitivity (0.76-0.89) but highest specificity (0.33-0.36) overall and for each subgroup. Algorithm B was the most sensitive strategy overall (0.97) and for MSM (HIV-infected 0.97; HIV-uninfected 1.00). For women, hrHPV testing and both algorithms yielded higher sensitivity than cytology (0.96, 0.98, and 0.96). Specificity was low for all strategies/subgroups (range, 0.16-0.36). CONCLUSIONS: Screening algorithms that incorporate cytology and hrHPV testing significantly increased sensitivity but decreased specificity to detect anal precancer/cancer among high-risk populations.

RESUMO

Non-AIDS-defining cancers are a growing source of morbidity for people with HIV globally. Although people living with HIV have a disproportionately increased risk of developing virally mediated cancers, cancer burden for common non-AIDS-defining cancers that are not virally associated and are linked to ageing, such as prostate cancer, is becoming higher than for virally mediated cancers. Ageing, behavioural, and HIV-specific factors drive the incidence and affect the outcomes of non-AIDS-defining cancers, presenting different challenges for addressing global morbidity and mortality from non-AIDS-defining cancer. Although large population-based studies have shown that people living with HIV with non-AIDS-defining cancers have poorer cancer outcomes than do people without HIV, current guidelines emphasise that people living with HIV with non-AIDS-defining cancers should receive standard, guideline-based treatment, and infectious disease and oncology providers should work closely to address potential drug interactions between antiretroviral therapy and antineoplastic treatment. Most trials target preventive measures focusing on non-AIDS-defining cancers. However, treatment trials for the optimal management of people living with HIV and non-AIDS-defining cancer, including interventions such as immunotherapies, are needed to improve non-AIDS-defining cancer outcomes.

RESUMO

INTRODUCTION: There are limited data on the incidence, predictors, and time to future liver abnormalities in patients with intrahepatic cholestasis of pregnancy (ICP). METHODS: Single-center retrospective study of pregnant women with and without ICP who delivered from 2005 to 2009 evaluating incidence and time to future liver abnormalities. Women returning for care with liver function tests at a minimum of 6 months postpartum were included. Liver disease diagnoses and liver functions test abnormalities were compared. Time to development of alanine aminotransferase (ALT) >25 U/L, alkaline phosphatase (ALP) >140 U/L, and diagnosis of liver disease (through imaging or clinical evaluation) were compared between women with and without ICP using Kaplan-Meier methods and Cox regression models. RESULTS: A total of 255 women with ICP and 131 age-matched control subjects with delivery during the same period were identified. Subjects in both groups were similar in follow-up time, age at pregnancy, prepregnancy body mass index, and ethnicity (≥75% were Hispanic in both groups). On univariate analyses, ICP was associated with increased incidence of ALT >25 U/L P < 0.01 ALP >140 U/L (P < 0.01) and liver disease (P = 0.03). Adjusting for metabolic factors, ICP diagnosis was associated with risk of future liver abnormalities: postpartum ALT >25 U/L (hazard ratio [HR] 1.9, P < 0.01), ALP >140 U/L (HR 3.4, P < 0.01), and liver disease (HR 1.5, P = 0.05). DISCUSSION: In our cohort of urban women, ICP diagnosis predicted risk of future liver disease and abnormal liver tests. Women with pregnancies complicated by ICP may benefit from surveillance for postpartum liver abnormalities.

RESUMO

In April 2020, in light of COVID-19-related blood shortages, the US Food and Drug Administration (FDA) reduced the deferral period for men who have sex with men (MSM) from its previous duration of 1 year to 3 months.Although originally born out of necessity, the decades-old restrictions on MSM donors have been mitigated by significant advancements in HIV screening, treatment, and public education. The severity of the ongoing COVID-19 pandemic-and the urgent need for safe blood products to respond to such crises-demands an immediate reconsideration of the 3-month deferral policy for MSM.We review historical HIV testing and transmission evidence, discuss the ethical ramifications of the current deferral period, and examine the issue of noncompliance with donor deferral rules. We also propose an eligibility screening format that involves an individual risk-based screening protocol and, unlike current FDA guidelines, does not effectively exclude donors on the basis of gender identity or sexual orientation. Our policy proposal would allow historically marginalized community members to participate with dignity in the blood donation process without compromising blood donation and transfusion safety outcomes.

RESUMO

BACKGROUND: Practice variation has been well documented across the US health care system but has not been explored in reconstructive surgical choice after keratinocyte carcinoma (KC) extirpation. OBJECTIVE: Assess practice variation in utilization of complex (flap or graft) reconstruction after excision of KC on the nose among a multidisciplinary group of reconstructive surgeons (Mohs micrographic and plastic surgery). MATERIALS AND METHODS: A randomly selected subset of surgically treated, routine, primary, invasive KCs on the nose between 2000 to 2012 at the Veterans Affairs (VA)-Boston Healthcare System were assessed. Patient factors, tumor factors, and individual surgeons with sufficient case volume were fit to a multivariate logistic regression model to assess between-surgeon differences in the odds of performing a complex reconstruction. RESULTS: Ten surgeons met the case volume threshold for analysis, encompassing 338 KC on the nose excised and reconstructed from 2000 to 2012. After adjusting for patient age, tumor diameter, and location, 6 surgeons performed significantly more complex reconstructions than the reference surgeon, and the case-adjusted predicted probability of complex reconstruction ranged from 7% to 99% (p ≤ .0001). CONCLUSION: Marked practice variation in reconstruction choice exists among surgeons after extirpation of KC on the nose at one VA health care system. High-quality comparative studies regarding optimal nasal reconstruction after extirpation of KC are needed.

RESUMO

BACKGROUND: The social determinants of health that influence steps in the entire Hepatitis C Virus (HCV) treatment cascade must be identified to achieve HCV elimination goals. This project aimed to evaluate the association of these factors with HCV treatment completion and return for sustained virologic response (SVR) testing. METHODS: We used retrospective cohort data from our primary care-based HCV treatment program that provides comprehensive harm reduction care to those who use or formerly used drugs. Among persons who began direct-acting antiviral HCV treatment between December 2014 and March 2018, we identified two outcomes: HCV treatment completion and return for SVR assessment 12 weeks after treatment end. Several predictors were ascertained including sociodemographic information, substance use, psychiatric symptoms and history, housing instability, and HCV treatment regimen. We then evaluated associations between predictors and outcomes using univariate and multivariable statistical methods. RESULTS: From a cohort of 329 patients treated in an urban primary care center, multivariable analysis identified housing instability as a single significant predictor for HCV treatment completion (odds ratio [OR]: 0.3; 95% confidence interval [CI]: 0.1-0.9). Among patients completing treatment, 226 (75%) returned for SVR assessment; the sole predictor of this outcome was Medicaid as primary insurance (compared to other insurances; OR 0.3; 0.1-0.7). CONCLUSIONS: Innovative strategies to help unstably housed persons complete HCV treatment are urgently needed in order to reach HCV elimination targets. Educational and motivational strategies should be developed to promote individuals with Medicaid in particular to return for SVR viral load testing, a critical post-treatment component of the HCV treatment cascade.

RESUMO

BACKGROUND: There are limited data regarding the clinical impact of coronavirus disease 2019 (COVID-19) on people living with human immunodeficiency virus (PLWH). In this study, we compared outcomes for PLWH with COVID-19 to a matched comparison group. METHODS: We identified 88 PLWH hospitalized with laboratory-confirmed COVID-19 in our hospital system in New York City between 12 March and 23 April 2020. We collected data on baseline clinical characteristics, laboratory values, HIV status, treatment, and outcomes from this group and matched comparators (1 PLWH to up to 5 patients by age, sex, race/ethnicity, and calendar week of infection). We compared clinical characteristics and outcomes (death, mechanical ventilation, hospital discharge) for these groups, as well as cumulative incidence of death by HIV status. RESULTS: Patients did not differ significantly by HIV status by age, sex, or race/ethnicity due to the matching algorithm. PLWH hospitalized with COVID-19 had high proportions of HIV virologic control on antiretroviral therapy. PLWH had greater proportions of smoking (P < .001) and comorbid illness than uninfected comparators. There was no difference in COVID-19 severity on admission by HIV status (P = .15). Poor outcomes for hospitalized PLWH were frequent but similar to proportions in comparators; 18% required mechanical ventilation and 21% died during follow-up (compared with 23% and 20%, respectively). There was similar cumulative incidence of death over time by HIV status (P = .94). CONCLUSIONS: We found no differences in adverse outcomes associated with HIV infection for hospitalized COVID-19 patients compared with a demographically similar patient group.

RESUMO

BACKGROUND: Electrocautery ablation (EA) is a common treatment modality for patients with anal high-grade squamous intraepithelial lesions (HSILs), but to the authors' knowledge its effectiveness has been understudied. The objective of the current study was to determine ablation outcomes and to identify clinicopathological factors associated with postablation disease recurrence. METHODS: A total of 330 people living with HIV with de novo intra-anal HSIL who were treated with EA from 2009 to 2016 were studied retrospectively. Using long-term, surveillance high-resolution anoscopy biopsy data, treatment failures were classified as local recurrence (HSIL noted at the treated site at the time of surveillance) or overall recurrence (HSIL noted at treated or untreated sites). The associations between these outcomes and clinical factors were analyzed using Cox proportional hazards models. RESULTS: Approximately 88% of participants were men who have sex with men. The median age of study  participants was 45.5 years (range, 35-51 years) and approximately 49% had multiple index HSILs (range, 2-6 index HSILs). At a median of 12.2 months postablation (range, 6.3-20.9 months postablation), approximately 45% of participants had developed local recurrence whereas 60% had developed overall recurrence. Current cigarette smoking, HIV viremia (HIV-1 RNA ≥100 copies/mL), and multiple index HSILs were found to be predictive of local recurrence. Overall recurrence was more common in current smokers and those with multiple index lesions. In multivariable models that included human papillomavirus (HPV) genotypes, baseline and persistent infections with HPV-16 and/or HPV-18 were found to be significantly associated with both local and overall recurrence. CONCLUSIONS: EA is an effective treatment modality for anal HSIL in people living with HIV, but rates of disease recurrence are substantial. Multiple index HSILs, HIV viremia, current cigarette smoking, and both baseline and persistent infection with HPV-16 and/or HPV-18 appear to negatively impact treatment success. Ongoing surveillance is imperative to capture recurrence early and improve long-term treatment outcomes.

RESUMO

Women living with HIV (WLHIV) are at increased risk for human papillomavirus (HPV)-associated anal cancer. Given the "field effect" of HPV pathogenesis, some recommend that anal cancer screening should be limited to WLHIV with prior genital disease. This study aimed to characterize the relationship between anal and genital disease in WLHIV in order to better inform anal cancer screening guidelines. We retrospectively studied 153 WLHIV with biopsy-proven anal high-grade squamous intraepithelial lesions (AHSIL) and long-term evaluable cervical/vaginal/vulvar histopathology. Based on the absence or presence of genital HSIL, subjects were categorized as having isolated AHSIL or multicentric HSIL. Demographics, HIV parameters and cervical/anal HPV status were recorded. Chi-square test was used for bivariate analyses. Of 153 WLHIV with AHSIL, 110 (72%) had isolated AHSIL, while 43 (28%) had multicentric HSIL (28 cervical, 16 vulvar, and 8 vaginal HSIL). The median genital surveillance was 8 years (range 1-27). Cervical HPV16/18 infection was associated with multicentric disease (P = 0.001). Overall, 53% of multicentric cases presented genital HSIL preceding AHSIL with median interval 13 years (range 2-23). Paired anal and cervical high-risk HPV results were available for 60 women within 12 months of AHSIL diagnosis: 30 (50%) had anal infection alone, while 30 (50%) had anal/cervical coinfection by 16/18 (15%), non-16/18 (13%), or different types (22%). In conclusion, WLHIV frequently develop AHSILs without pre-existing genital disease or after long latency following a genital HSIL diagnosis. Our findings support anal cancer screening for WLHIV irrespective of prior genital disease.

RESUMO

BACKGROUND: Data on patients with coronavirus disease 2019 (COVID-19) who return to hospital after discharge are scarce. Characterization of these patients may inform post-hospitalization care. OBJECTIVE: To describe clinical characteristics of patients with COVID-19 who returned to the emergency department (ED) or required readmission within 14 days of discharge. DESIGN: Retrospective cohort study of SARS-COV-2-positive patients with index hospitalization between February 27 and April 12, 2020, with ≥ 14-day follow-up. Significance was defined as P < 0.05 after multiplying P by 125 study-wide comparisons. PARTICIPANTS: Hospitalized patients with confirmed SARS-CoV-2 discharged alive from five New York City hospitals. MAIN MEASURES: Readmission or return to ED following discharge. RESULTS: Of 2864 discharged patients, 103 (3.6%) returned for emergency care after a median of 4.5 days, with 56 requiring inpatient readmission. The most common reason for return was respiratory distress (50%). Compared with patients who did not return, there were higher proportions of COPD (6.8% vs 2.9%) and hypertension (36% vs 22.1%) among those who returned. Patients who returned also had a shorter median length of stay (LOS) during index hospitalization (4.5 [2.9,9.1] vs 6.7 [3.5, 11.5] days; Padjusted = 0.006), and were less likely to have required intensive care on index hospitalization (5.8% vs 19%; Padjusted = 0.001). A trend towards association between absence of in-hospital treatment-dose anticoagulation on index admission and return to hospital was also observed (20.9% vs 30.9%, Padjusted = 0.06). On readmission, rates of intensive care and death were 5.8% and 3.6%, respectively. CONCLUSIONS: Return to hospital after admission for COVID-19 was infrequent within 14 days of discharge. The most common cause for return was respiratory distress. Patients who returned more likely had COPD and hypertension, shorter LOS on index-hospitalization, and lower rates of in-hospital treatment-dose anticoagulation. Future studies should focus on whether these comorbid conditions, longer LOS, and anticoagulation are associated with reduced readmissions.

RESUMO

OBJECTIVES: The primary objective was to compare the performance of 3 different abbreviated MRI (AMRI) sets extracted from a complete gadoxetate-enhanced MRI obtained for hepatocellular carcinoma (HCC) screening. Secondary objective was to perform a preliminary cost-effectiveness analysis, comparing each AMRI set to published ultrasound performance for HCC screening in the USA. METHODS: This retrospective study included 237 consecutive patients (M/F, 146/91; mean age, 58 years) with chronic liver disease who underwent a complete gadoxetate-enhanced MRI for HCC screening in 2017 in a single institution. Two radiologists independently reviewed 3 AMRI sets extracted from the complete exam: non-contrast (NC-AMRI: T2-weighted imaging (T2wi)+diffusion-weighted imaging (DWI)), dynamic-AMRI (Dyn-AMRI: T2wi+DWI+dynamic T1wi), and hepatobiliary phase AMRI (HBP-AMRI: T2wi+DWI+T1wi during the HBP). Each patient was classified as HCC-positive/HCC-negative based on the reference standard, which consisted in all available patient data. Diagnostic performance for HCC detection was compared between sets. Estimated set characteristics, including historical ultrasound data, were incorporated into a microsimulation model for cost-effectiveness analysis. RESULTS: The reference standard identified 13/237 patients with HCC (prevalence, 5.5%; mean size, 33.7 ± 30 mm). Pooled sensitivities were 61.5% for NC-AMRI (95% confidence intervals, 34.4-83%), 84.6% for Dyn-AMRI (60.8-95.1%), and 80.8% for HBP-AMRI (53.6-93.9%), without difference between sets (p range, 0.06-0.16). Pooled specificities were 95.5% (92.4-97.4%), 99.8% (98.4-100%), and 94.9% (91.6-96.9%), respectively, with a significant difference between Dyn-AMRI and the other sets (p < 0.01). All AMRI methods were effective compared with ultrasound, with life-year gain of 3-12 months against incremental costs of US$ < 12,000. CONCLUSIONS: NC-AMRI has limited sensitivity for HCC detection, while HBP-AMRI and Dyn-AMRI showed excellent sensitivity and specificity, the latter being slightly higher for Dyn-AMRI. Cost-effectiveness estimates showed that AMRI is effective compared with ultrasound. KEY POINTS: • Comparison of different abbreviated MRI (AMRI) sets reconstructed from a complete gadoxetate MRI demonstrated that non-contrast AMRI has low sensitivity (61.5%) compared with contrast-enhanced AMRI (80.8% for hepatobiliary phase AMRI and 84.6% for dynamic AMRI), with all sets having high specificity. • Non-contrast and hepatobiliary phase AMRI can be performed in less than 14 min (including set-up time), while dynamic AMRI can be performed in less than 17 min. • All AMRI sets were cost-effective for HCC screening in at-risk population in comparison with ultrasound.

RESUMO

BACKGROUND: People living with HIV have high rates of anal human papillomavirus infection and anal precancer/cancer. OBJECTIVE: This study aims to: 1) determine human papillomavirus subtype distribution among people living with HIV with anal high-grade squamous intraepithelial lesions; 2) compare the clinicopathological characteristics of patients with anal high-grade squamous intraepithelial lesions by human papillomavirus 16 status; and 3) investigate high-risk human papillomavirus negative anal high-grade squamous intraepithelial lesion cases. DESIGN: In this retrospective study, 700 people living with HIV who have biopsy-proven anal high-grade squamous intraepithelial lesions were reviewed for demographics, cytological diagnoses, and human papillomavirus testing results for human papillomavirus 16, 18, and 12 other high-risk types. For human papillomavirus-negative subjects, corresponding biopsies were genotyped by using real-time polymerase chain reaction. SETTINGS: This study was conducted in a large urban HIV clinic system and major referral center for anal cancer screening. PATIENTS: Median age was 46 years (range, 20-76). Ninety-one percent of the patients were men who have sex with men. MAIN OUTCOME MEASURES: The primary outcome measure was the association between demographic variables and human papillomavirus 16 status. RESULTS: Anal cytology was unsatisfactory (5%), benign (13%), atypical squamous cells of undetermined significance (35%), low-grade squamous intraepithelial lesion (36%), and high-grade squamous intraepithelial lesions (11%). Human papillomavirus cotesting results were negative (n = 38, 5%), human papillomavirus 16 (n = 303, 43%), human papillomavirus 18 (n = 78, 11%), or exclusively non-16/18 types (n = 281, 40%). Human papillomavirus 16 positivity was associated with ≥3 high-grade lesions and ≥ low-grade squamous intraepithelial lesion cytology (p < 0.001). Age, race/ethnicity, sex, smoking, CD4+ T-cell count, and HIV viral load did not differ by status of human papillomavirus 16 (p > 0.05). For human papillomavirus-negative cases, human papillomavirus genotyping of biopsies was positive for high-risk (n = 14, 36%) or possibly carcinogenic types (n = 12, 32%), or negative (n = 12, 32%). LIMITATIONS: This was a retrospective data analysis, and it pooled the results for 12 high-risk human papillomavirus types rather than individual types. CONCLUSIONS: Nearly all people living with HIV and anal high-grade squamous intraepithelial lesions test positive for high-risk human papillomavirus on anal swabs; negative results may be due to sampling error, L1-based polymerase chain reaction assay, or human papillomavirus types not captured by standard clinical assays. Patients who have human papillomavirus 16-positive anal high-grade squamous intraepithelial lesions are indistinguishable from others based on demographic and clinical characteristics, underscoring the potential role of human papillomavirus testing for anal cancer screening.

PACIENTES PORTADORES DE VIH CON PRECURSORES DE CÁNCER DE ANO: CARACTERÍSTICAS CLINICOPATOLÓGICAS Y DISTRIBUCIÓN DEL SUBTIPO VPH: Los pacientes portadores de VIH tienen altas tasas de infección por VPH y alto riesgo de desarrolar lesiones precáncerosas / cáncerosas del ano.(1) Determinar la distribución del subtipo de VPH entre las personas portadoras de VIH con lesiones intraepiteliales escamosas anales de alto grado. (2) Comparar las características clinicopatológicas de pacientes con lesiones intraepiteliales escamosas anales de alto grado del subtipo VPH 16. (3) Investigar casos de lesiones intraepiteliales escamosas anales de alto grado negativas para el VPH de alto riesgo.Estudio retrospectivo sobre 700 personas portadoras de VIH con lesiones intraepiteliales escamosas anales de alto grado confirmadas por biopsia. Los datos fueron revisados para determinar información demográfica, diagnósticos citológicos y resultados de tipización en el VPH subtipos 16 y 18, y otros 12 tipos de alto riesgo. Para los individuos negativos al VPH, se analizó el genotipo en las biopsias correspondientes mediante test de PCR en tiempo real.Extenso sistema de clinicas urbanas tratando VIH y un importante centro de referencia para la detección del cáncer analla mediana de edad poblacional fue de 46 años (rango, 20-76). 91% eran hombres que tenían sexo con hombres.Asociación entre las variables demográficas y el estado del VPH subtipo16.la citología anal fue insatisfactoria (5%), benigna (13%), células escamosas atípicas de importancia indeterminada (35%), lesión intraepitelial escamosa de bajo grado (36%) y lesiones intraepiteliales escamosas de alto grado (11%). Los resultados de la prueba conjunta del VPH fueron negativos (n = 38, 5%), el virus del VPH subtipo 16 (n = 303, 43%), el VPH subtipo 18 (n = 78, 11%) o los subtipos exclusivamente no 16/18 (n = 281, 40%). La positividad del VPH subtipo 16 se encotraba asociado con ≥3 lesiones de alto grado y ≥ células escamosas atípicas en la prueba de citología de indeterminada importancia (p < 0.001). La edad, la raza / etnia, el sexo, el tabaquismo, el recuento de células T CD4 + y la carga viral del VIH no difirieron según el estado del VPH subtipo 16 (p > 0.05). Para los casos negativos al VPH, el genotipo del virus del papiloma humano de las biopsias fue positivo para los tipos de alto riesgo (n = 14, 36%) o posiblemente carcinogénicos (n = 12, 32%), o negativo (n = 12, 32%).Análisis de datos retrospectivos, con resultados agrupados para 12 tipos de VPH de alto riesgo en lugar de tipos individuales.Casi todas las personas portadoras de VIH con lesiones intraepiteliales escamosas anales de alto grado dan positivo para el VPH de alto riesgo al muestreo de hisopos anales; Los resultados negativos pueden deberse a un error en el muestreo y al análisis de PCR basado en L1 o subtipos de VPH no obtenidos en los ensayos clínicos estándar. Los pacientes con lesiones intraepiteliales escamosas anales de alto grado positivas para el VPH subtipo 16 no son identificables de los demás, en función de las características demográficas y clínicas, lo que minimiza el rol potencial de la prueba del VPH en la detección del cáncer anal.

RESUMO

BACKGROUND: The addition of cisplatin or cetuximab to radiation therapy (RT) improves outcomes in comparison with RT alone in the nonoperative management of head and neck squamous cell carcinoma (HNSCC), but limited data exist for comparing these approaches. Using Veterans Health Affairs data, this study compared the outcomes of patients treated with RT plus cisplatin or cetuximab. METHODS: Patients with stage III to IVb HNSCC who had been treated nonsurgically with RT and cisplatin or cetuximab from 2000 to 2016 within the Veterans Health Affairs system were identified. Patients were analyzed by the drug used in the first treatment cycle (intent to treat). Overall survival (OS) was compared by treatment group with Cox regression models, and propensity score (PS) methods were used to account for a treatment allocation bias. The risk of toxicities was determined, with logistic regression models fit into propensity-matched cohorts. RESULTS: A total of 4520 patients were included in the analysis with a median follow-up of 3 years: 83% received cisplatin. Cisplatin patients were younger (P < .001) and had fewer comorbidities (P < .001). In an unmatched analysis, cetuximab was associated with inferior OS (P < .001). After PS matching, cetuximab treatment remained statistically significantly associated with inferior OS (1.7 vs 4.1 years; hazard ratio, 1.61; 95% confidence interval, 1.44-1.79; P < .001). These differences remained significant across all primary HNSCC subsites and in comparison with low- and high-dose cisplatin. CONCLUSIONS: Cetuximab with RT yields inferior OS in comparison with cisplatin for the nonoperative management of stage III to IVb HNSCC. According to this study, cisplatin may be the most appropriate partner for RT in this setting.

RESUMO

PURPOSE: Lung cancer risk models optimise screening by identifying subjects at highest risk, but none of them consider emphysema, a risk factor identifiable on baseline screen. Subjects with a negative baseline low-dose CT (LDCT) screen are at lower risk for subsequent diagnosis and may benefit from risk stratification prior to additional screening, thus we investigated the role of radiographic emphysema as an additional predictor of lung cancer diagnosis in participants with negative baseline LDCT screens of the National Lung Screening Trial. METHODS: Our cohorts consist of participants with a negative baseline (T0) LDCT screen (n=16 624) and participants who subsequently had a negative 1-year follow-up (T1) screen (n=14 530). Lung cancer risk scores were calculated using the Bach, PLCOm2012 and Liverpool Lung Project models. Risk of incident lung cancer diagnosis at the end of the study and number screened per incident lung cancer were compared between participants with and without radiographic emphysema. RESULTS: Radiographic emphysema was independently associated with nearly double the hazard of lung cancer diagnosis at both the second (T1) and third (T2) annual LDCT in all three risk models (HR range 1.9-2.0, p<0.001 for all comparisons). The number screened per incident lung cancer was considerably lower in participants with radiographic emphysema (62 vs 28 at T1 and 91 vs 40 at T2). CONCLUSION: Radiographic emphysema is an independent predictor of lung cancer diagnosis and may help guide decisions surrounding further screening for eligible patients.
