B Introduction: b Primary cutaneous B-cell lymphomas (PCBCL) are rare lymphoproliferative disorders characterized by an indolent course and a life-long tendency to relapse. B Methods: b We retrospectively collected data on patients diagnosed with primary cutaneous marginal zone lymphoma (PCMZL) and follicular center lymphoma (PCFCL) who received at least one cycle of ILR from 2010 to 2022 at our Center. All patients experienced at least a partial response (PR), with 58% of complete responses (CR), the majority (80%) reached with only one ILR cycle. [Extracted from the article]

Background: Endometrial cancer is a hormone-dependent cancer, and estrogens play a relevant role in its etiology. However, little is known about the effects of environmental pollutants that act as xenoestrogens or that influence estrogenic activity through different pathways., Objective: We aimed to assess the relationship between the combined estrogenic activity of mixtures of xenoestrogens present in serum samples and the risk of endometrial cancer in the Screenwide case-control study., Methods: The total effective xenoestrogen burden (TEXB) attributable to organohalogenated compounds ( TEXB- α ) and to endogenous hormones and more polar xenoestrogens ( TEXB- β ) was assessed in serum from 156 patients with endometrial cancer (cases) and 150 controls by combining chemical extraction and separation by high-performance liquid chromatography with the E-SCREEN bioassay for estrogenicity., Results: Median TEXB- α and TEXB- β levels for cases (0.30 and 1.25  Eeq pM / mL , respectively) and controls (0.42 and 1.28  Eeq pM / mL , respectively) did not significantly differ ( p = 0.653 and 0.933, respectively). An inverted-U risk trend across serum TEXB- α and TEXB- β levels was observed in multivariate adjusted models: Positive associations were observed for the second category of exposure in comparison to the lowest category of exposure [ odds ratio  ( OR ) = 2.11 (95% CI: 1.13, 3.94) for TEXB- α , and OR = 3.32 (95% CI: 1.62, 6.81) for TEXB- β ], whereas no significant associations were observed between the third category of exposure and the first [ OR = 1.22 (95% CI: 0.64, 2.31) for TEXB- α , and OR = 1.58 (95% CI: 0.75, 3.33) for TEXB- β ]. In mutually adjusted models for TEXB- α and TEXB- β levels, the association of TEXB- α with endometrial cancer risk was attenuated [ OR = 1.45 (95% CI: 0.61, 3.47) for the second category of exposure], as well as estimates for TEXB- β ( OR = 2.68 ; 95% CI: 1.03, 6.99). Most of the individual halogenated contaminants showed no associations with both TEXB and endometrial cancer., Conclusions: We evaluated serum total xenoestrogen burden in relation to endometrial cancer risk and found an inverted-U risk trend across increasing categories of exposure. The use of in vitro bioassays with human samples may lead to a paradigm shift in the way we understand the negative impact of chemical mixtures on human health effects. These results are relevant from a public health perspective and for decision-makers in charge of controlling the production and distribution of chemicals with xenoestrogenic activity. https://doi.org/10.1289/EHP13202.

Data on the role of circadian related factors in the etiology of endometrial cancer are scarce. We collected individual data on night shift work or daily sleep duration from 7,207 cases and 22,027 controls participating in 11 studies from the Epidemiology of Endometrial Cancer Consortium (E2C2). Main analyses were performed among postmenopausal women: 6,335 endometrial cancer cases and 18,453 controls. Using individual data, study-specific odd ratios (ORs) and their corresponding 95% confidence intervals (CIs) were estimated with logistic regression and pooled analyses were conducted using random-effects meta-analyses. A non-significant inverse association was observed between endometrial cancer and night shift work (OR=0.89, 95%CI=0.72-1.09; I 2 =0.0%, P heterogeneity= 0.676). Associations did not vary by shift type (permanent or rotating), or duration of night work. Categorizations of short (<7h) or long (≥9h) sleep duration were not associated with endometrial cancer risk (OR short =1.02, 95%CI=0.95-1.10; I 2 =55.3%, P heterogeneity =0.022; OR long =0.93, 95%CI=0.81-1.06; I 2 =11.5%, P heterogeneity =0.339). No associations were observed per 1-h increment of sleep (OR=0.98, 95%CI=0.95-1.01; I 2 =46.1%, P heterogeneity =0.063), but an inverse association was identified among obese women (OR=0.93, 95%CI=0.89-0.98 per 1-h increment; I 2 =12.7%, P heterogeneity =0.329). Overall, these pooled analyses provide evidence that night shift work and sleep duration are not strong risk factors for endometrial cancer in postmenopausal women., Competing Interests: Declaration of competing interest The authors of this paper have no conflicts of interest to disclose relevant to the present work., (Copyright © 2023 Elsevier Ltd.

Background: Endometrial cancer is the most common gynaecological tumour in developed countries and disease burden is expected to increase over the years. Identifying modifiable risk factors may help developing strategies to reduce the expected increasing incidence of these neoplasms., Objective: This study evaluates the association between occupational exposure to pesticides and endometrial cancer using data from a recent case-control study in Spain., Methods: The analyses included data from 174 consecutive incident endometrial cancer cases and 216 hospital controls frequency-matched by age. Data were collected through structured epidemiological questionnaires and exposure to pesticides was assessed using a Spanish job-exposure matrix (MatEmESp)., Results: Overall, 12% of controls and 18% of cases were occupationally exposed to pesticides. We observed a positive association between occupational exposure to pesticides and endometrial cancer (OR = 2.08; 95% CI = 1.13-3.88 compared to non-exposed). In general, exposures that occurred farther in the past were significantly associated with endometrial cancer. Exposure to insecticides, fungicides and herbicides were positively associated with endometrial cancer (OR = 2.08; 95% CI = 1.13-3.88, OR = 4.40; 95% CI = 1.65-13.33, and OR = 5.25; 95% CI = 1.84-17.67, respectively). The agricultural, poultry and livestock activities scenario was associated with endometrial cancer (OR = 4.16; 95% CI = 1.59-12.32), while the cleaning exposure scenario was not (OR = 1.22; 95% CI = 0.55-2.67)., Conclusions: Assessment of occupational exposure to pesticides assessed using a Spanish job-exposure matrix revealed a positive association with endometrial cancer. The elucidation of the role of pesticide compounds on endometrial cancer should shed a light on the aetiology of this tumour., (© 2023. The Author(s).)

Purpose: Current diagnostic methods for endometrial cancer lack specificity, leading to many women undergoing invasive procedures. The aim of this study was to evaluate somatic mutations in urine to accurately discriminate patients with endometrial cancer from controls., Experimental Design: Overall, 72 samples were analyzed using next-generation sequencing (NGS) with molecular identifiers targeting 47 genes. We evaluated urine supernatant samples from women with endometrial cancer (n = 19) and age-matched controls (n = 20). Cell pellets from urine and plasma samples from seven cases were sequenced; further, we also evaluated paired tumor samples from all cases. Finally, immunohistochemical markers for molecular profiling were evaluated in all tumor samples., Results: Overall, we were able to identify mutations in DNA from urine supernatant samples in 100% of endometrial cancers. In contrast, only one control (5%) showed variants at a variant allele frequency (VAF) ≥ 2% in the urine supernatant samples. The molecular classification obtained by using tumor samples and urine samples showed good agreement. Analyses in paired samples revealed a higher number of mutations and VAF in urine supernatants than in urine cell pellets and blood samples., Conclusions: Evaluation of somatic mutations using urine samples may offer a user-friendly and reliable tool for endometrial cancer detection and molecular classification. The diagnostic performance for endometrial cancer detection was very high, and cases could be molecularly classified using these noninvasive and self-collected samples. Additional multicenter evaluations using larger sample sizes are needed to validate the results and understand the potential of urine samples for the early detection and prognosis of endometrial cancer., (©2023 American Association for Cancer Research.)

Introduction: New approaches are being developed to early detect endometrial cancer using molecular biomarkers. These approaches offer high sensitivities and specificities, representing a promising horizon to develop early detection strategies., Objective: To evaluate the effectiveness and cost-effectiveness of introducing molecular testing to detect endometrial cancer in women with postmenopausal bleeding compared to the current strategy using the national healthcare service perspective., Methods: A Markov model was developed to assess the two early detection strategies. The model predicts the number of hysterectomies, lifetime expectancy, quality-adjusted life-years, endometrial cancer prevalence and incidence, mortality from endometrial cancer and the lifetime cost of screening, diagnosis, and treatment. Strategies were compared using the incremental cost-effectiveness ratio., Results: The molecular strategy reduces 1.9% of the overall number of hysterectomies and the number of undetected cancer cases by 65%. Assuming a molecular test cost of 310€, the molecular strategy has an incremental cost of -32,952€ per QALY gained, being more effective and less expensive than the current strategy., Conclusions: The introduction of molecular testing to diagnose endometrial cancer in women presenting postmenopausal bleeding provides more health benefit at a lower cost, and therefore has the potential to be cost-effective., (© 2023.

Background: The incidence of endometrial cancer is increasing worldwide. While delays in diagnosis reduce survival, case molecular misclassification might be associated with under- and over-treatment. The objective of this study was to evaluate genetic alterations to detect and molecularly classify cases of endometrial cancer using non-invasive samples., Methods: Consecutive patients with incident endometrial cancer (N = 139) and controls (N = 107) from a recent Spanish case-control study were included in this analysis. Overall, 339 cervicovaginal samples (out of which 228 were clinician-collected and 111 were self-collected) were analysed using a test based on next-generation sequencing (NGS), which targets 47 genes. Immunohistochemical markers were evaluated in 133 tumour samples. A total of 159 samples were used to train the detection algorithm and 180 samples were used for validation., Findings: Overall, 73% (N = 94 out of 129 clinician-collected samples, and N = 66 out of 90 self-collected samples) of endometrial cancer cases had detectable mutations in clinician-collected and self-collected samples, while the specificity was 80% (79/99) for clinician-collected samples and 90% (19/21) for self-collected samples. The molecular classifications obtained using tumour samples and non-invasive gynaecologic samples in our study showed moderate-to-good agreement. The molecular classification of cases of endometrial cancer into four groups using NGS of both clinician-collected and self-collected cervicovaginal samples yielded significant differences in disease-free survival. The cases with mutations in POLE had an excellent prognosis, whereas the cases with TP53 mutations had the poorest clinical outcome, which is consistent with the data on tumour samples., Interpretation: This study classified endometrial cancer cases into four molecular groups based on the analysis of cervicovaginal samples that showed significant differences in disease-free survival. The molecular classification of endometrial cancer in non-invasive samples may improve patient care and survival by indicating the early need for aggressive surgery, as well as reducing referrals to highly specialized hospitals in cancers with good prognosis. Validation in independent sets will confirm the potential for molecular classification in non-invasive samples., Funding: This study was funded by a competitive grant from Instituto de Salud Carlos III through the projects PI19/01835, PI23/00790, and FI20/00031, CIBERESP CB06/02/0073 and CIBERONC CB16/12/00231, CB16/12/00234 (Co-funded by European Regional Development Fund.

Background: Endometrial cancer risk stratification may help target interventions, screening, or prophylactic hysterectomy to mitigate the rising burden of this cancer. However, existing prediction models have been developed in select cohorts and have not considered genetic factors., Methods: We developed endometrial cancer risk prediction models using data on postmenopausal White women aged 45-85 years from 19 case-control studies in the Epidemiology of Endometrial Cancer Consortium (E2C2). Relative risk estimates for predictors were combined with age-specific endometrial cancer incidence rates and estimates for the underlying risk factor distribution. We externally validated the models in 3 cohorts: Nurses' Health Study (NHS), NHS II, and the Prostate, Lung, Colorectal and Ovarian (PLCO) Cancer Screening Trial., Results: Area under the receiver operating characteristic curves for the epidemiologic model ranged from 0.64 (95% confidence interval [CI] = 0.62 to 0.67) to 0.69 (95% CI = 0.66 to 0.72). Improvements in discrimination from the addition of genetic factors were modest (no change in area under the receiver operating characteristic curves in NHS; PLCO = 0.64 to 0.66). The epidemiologic model was well calibrated in NHS II (overall expected-to-observed ratio [E/O] = 1.09, 95% CI = 0.98 to 1.22) and PLCO (overall E/O = 1.04, 95% CI = 0.95 to 1.13) but poorly calibrated in NHS (overall E/O = 0.55, 95% CI = 0.51 to 0.59)., Conclusions: Using data from the largest, most heterogeneous study population to date (to our knowledge), prediction models based on epidemiologic factors alone successfully identified women at high risk of endometrial cancer. Genetic factors offered limited improvements in discrimination. Further work is needed to refine this tool for clinical or public health practice and expand these models to multiethnic populations., (© The Author(s) 2023. Published by Oxford University Press.)

Purpose: Endometrial cancer (EC) incidence has been rising over the past 10 years. Delays in diagnosis reduce survival and necessitate more aggressive treatment. We aimed to develop and validate a simple, noninvasive, and reliable triage test for EC to reduce the number of invasive diagnostic procedures and improve patient survival., Methods: We developed a test to screen and triage women with suspected EC using 726 cervical smear samples from women with and without EC, and validated the test in 562 cervicovaginal samples using three different collection methods (cervical smear: n = 248; vaginal swab: n = 63; and self-collection: n = 251) and four different settings (case/control: n = 388; cohort of women presenting with postmenopausal bleeding: n = 63; a cohort of high-risk women with Lynch syndrome: n = 25; and a nested case/control setting from a screening cohort and samples taken up to 3 years before EC diagnosis: n = 86)., Results: We describe the W omen's cancer risk ID entification - q uantitative polymerase chain reaction test for E ndometrial C ancer (WID-qEC), a three-marker test that evaluates DNA methylation in gene regions of GYPC and ZSCAN12 . In cervical, self-collected, and vaginal swab samples derived from symptomatic patients, it detected EC with sensitivities of 97.2% (95% CI, 90.2 to 99.7), 90.1% (83.6 to 94.6), and 100% (63.1 to 100), respectively, and specificities of 75.8% (63.6 to 85.5), 86.7% (79.3 to 92.2), and 89.1% (77.8 to 95.9), respectively. The WID-qEC identified 90.9% (95% CI, 70.8 to 98.9) of EC cases in samples predating diagnosis up to 1 year. Test performance was similar across menopausal status, age, stage, grade, ethnicity, and histology., Conclusion: The WID-qEC is a noninvasive reliable test for triage of women with symptoms suggestive of ECs. Because of the potential for self-collection, it could improve early diagnosis and reduce the reliance for in-person visits., Competing Interests: Chiara HerzogStock and Other Ownership Interests: Sola Diagnostics GmbHPatents, Royalties, Other Intellectual Property: Named inventor on a patent combining epigenetic signatures for detection and risk stratification for breast cancer (WID-qtBC, Women's cancer risk identification—quantitative trait Breast Cancer) Paula Peremiquel-TrillasHonoraria: WerfenTravel, Accommodations, Expenses: Werfen Joan BrunetConsulting or Advisory Role: MSD Oncology, AstraZeneca SpainTravel, Accommodations, Expenses: GlaxoSmithKline Jordi PonceConsulting or Advisory Role: Medtronic, Abex, KCI Xavier Matias-GuiuConsulting or Advisory Role: AstraZeneca, Lilly, Amgen, Janssen, GlaxoSmithKlineTravel, Accommodations, Expenses: GlaxoSmithKline, Roche Laia AlemanyOther Relationship: Integrated DNA Technologies (Inst), Roche (Inst)Uncompensated Relationships: Roche (Inst) Adam RosenthalConsulting or Advisory Role: AbcodiaResearch Funding: Abcodia (Inst) David CibulaConsulting or Advisory Role: AstraZeneca, Sotio, Roche, GlaxoSmithKline, Novocure, Akeso Biopharma, MSD, Mersana Karin SundströmConsulting or Advisory Role: Merck (Inst)Research Funding: Merck (Inst) Laura CostasHonoraria: Roche Sequencing SolutionsOther Relationship: Integrated DNA Technologies (Inst), Roche (Inst)Uncompensated Relationships: Roche (Inst) Martin WidschwendterPatents, Royalties, Other Intellectual Property: I am a shareholder of Sola Diagnostics GmbH, which holds an exclusive license to the intellectual property that protects the commercialization of the WID tests.

Screenwide is a case-control study (2017−2021) including women with incident endometrial and ovarian cancers (EC and OC), BRCA1/2 and MMR pathogenic variant carriers, and age-matched controls from three centers in Spain. Participants completed a personal interview on their sociodemographic factors, occupational exposure, medication, lifestyle, and medical history. We collected biological specimens, including blood samples, self-collected vaginal specimens, cervical pap-brush samples, uterine specimens, and, when available, tumor samples. The planned analyses included evaluation of the potential risk factors for EC/OC; evaluation of molecular biomarkers in minimally invasive samples; evaluation of the cost-effectiveness of molecular tests; and the generation of predictive scores to integrate different epidemiologic, clinical, and molecular factors. Overall, 182 EC, 69 OC, 98 BRCA pathogenic variant carriers, 104 MMR pathogenic variant carriers, and 385 controls were enrolled. The overall participation rate was 85.7%. The pilot study using 61 samples from nine EC cases and four controls showed that genetic variants at the variant allele fraction > 5% found in tumors (n = 61 variants across the nine tumors) were detected in paired endometrial aspirates, clinician-collected cervical samples, and vaginal self-samples with detection rates of 90% (55/61), 79% (48/61), and 72% (44/61) by duplex sequencing, respectively. Among the controls, only one somatic mutation was detected in a cervical sample. We enrolled more than 800 women to evaluate new early detection strategies. The preliminary data suggest that our methodological approach could be useful for the early detection of gynecological cancers.

Background: Circadian disruption caused by night work has been associated with hormonal-related cancers such as breast and prostate cancer. Data on the role of circadian factors in the aetiology of endometrial cancer, an oestrogen-associated cancer, are scarce., Methods: We examined the association between endometrial cancer and night shift work, chronotype (a characteristic correlating with preference for morning or evening activity) and sleep duration, in 180 incident cases and 218 hospital controls. Participants were interviewed face-to-face by trained interviewers to collect information on sociodemographic factors, familial, medical, occupational history (including work shifts), sleep duration and chronotype, and other lifestyle factors. We used logistic regression models adjusted for potential confounders to estimate ORs and 95% CIs., Results: After adjustment by potential confounders, we found an inverse not statistically significant association between ever worked in night shifts and endometrial cancer (OR=0.64; 95% CI=0.35 to 1.16). Associations were irrespective of shift type (permanent or rotating nights) or duration of night work. We did not observe any statistically significant association between endometrial cancer and sleep duration, while inconsistent patterns were observed for chronotype and endometrial cancer risk., Conclusions: These data do not support a role for circadian disruption in the carcinogenesis of endometrial cancer., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2022.

This study aimed to assess whether surgical practice had a significant impact on oncological outcomes among women who underwent robot-assisted radical hysterectomy for early-stage cervical cancer (≤IB1 or IIA1, FIGO 2009). The secondary objective was to audit the pre-surgical quality indicators (QI) proposed by the European Society of Gynaecological Oncology (ESGO). The top 5 of 10 centers in Spain and Portugal were included in the analysis. The hospitals were divided into group A ( n = 118) and group B ( n = 97), with recurrence rates of <10% and >10%, respectively. After balancing both groups using the propensity score, the ORs for all events were higher and statistically significant for group B (recurrences OR = 1.23, 95% CI = 1.13-1.15, p -value = 0.001; death OR = 1.10, 95% CI = 1.02-1.18, p -value = 0.012; disease-specific mortality OR r = 1.11, 95% CI = 1.04-1.19, p -value = 0.002). A higher surgical volume, higher participation in clinical trials, higher rate of MRI use for diagnosis, greater use of sentinel lymph node biopsies, and a favorable learning curve with low rates of early recurrences were observed among the centers with better oncological outcomes. These factors might have a significant impact on oncological outcomes not only after robot-assisted surgery, but also after laparoscopies and open surgeries in the treatment of cervical cancer.

Ovarian cancer is the most lethal gynaecological cancer in very-high-human-development-index regions. Ovarian cancer incidence and mortality rates are estimated to globally rise by 2035, although incidence and mortality rates depend on the region and prevalence of the associated risk factors. The aim of this study is to assess changes in incidence and mortality of ovarian cancer in Catalonia by 2030. Bayesian autoregressive age-period-cohort models were used to predict the burden of OC incidence and mortality rates for the 2015-2030 period. Incidence and mortality rates of ovarian cancer are expected to decline in Catalonia by 2030 in women ≥ 45 years of age. A decrease in ovarian-cancer risk was observed with increasing year of birth, with a rebound in women born in the 1980s. A decrease in mortality was observed for the period of diagnosis and period of death. Nevertheless, ovarian-cancer mortality remains higher among older women compared to other age groups. Our study summarizes the most plausible scenario for ovarian-cancer changes in terms of incidence and mortality in Catalonia by 2030, which may be of interest from a public health perspective for policy implementation.

Introduction: Cervical cytology is a well-stablished cervical cancer screening method. However, due to the anatomical continuity of the genital tract, it can also detect signs of endometrial disease. Our aim was to estimate the sensitivity of cervical cytology in endometrial cancer detection and prognosis in a large population over a 30-year period in a large academic tertiary hospital in Spain., Methodology: We performed a search for women diagnosed with endometrial cancer from 1990 to 2020, who were surgically treated and had a previous cervical cytology result. Information Technologies Department databases from Bellvitge University Hospital and the Screenwide case-control study's database were used. Cervical cytology results were classified as abnormal when squamous lesions, glandular atypia or malignant cells were identified., Results: Overall, we evaluated 371 women with endometrial cancer and a documented cervical cytology performed within 3 years previous to surgical treatment. Overall, the sensitivity of cervical cytology for endometrial cancer detection was 25.6%. Several clinico-pathological characteristics, such as non-endometrioid histology and a higher stage, were correlated with higher sensitivity., Discussion: We observed a low sensitivity of cervical cytology to effectively diagnose endometrial cancer. However, recent technological advances using genomics and epigenomics may offer a promising perspective to detect endometrial cancer with high sensitivity in these cervical specimens., (© 2021 The Authors.

Endometrial cancer is currently one of the most common gynecological cancers. Reported incidence rates vary in Spain depending on the region. We estimated what the incidence and mortality of endometrial cancers in Catalonia will be by 2030 and compared the predictions with data from 2010. Bayesian autoregressive age-period-cohort models were employed to predict incidence and mortality rates for 2015-2030. The incidence of endometrial cancer for women younger than 65 years was predicted to be lower in 2030 than in 2010, whereas it was predicted to be higher for women aged 65-74 years. Moreover, mortality rates for women aged ≥65 in 2030 are likely to exceed the rates in 2010. Five-year relative survival for all ages was slightly higher in the period 2005-2009 (79.3 %, 95 %CI: 75.8 %-82.9 %) compared with those in 1995-1999 (76.0 %, 95 %CI: 72.1 %-80.2 %). This plausible new scenario might be useful to plan new clinical and preventive strategies in the near future., (Copyright © 2020 Elsevier B.V. All rights reserved.)

Cervico-vaginal cytology is primarily a cervical cancer screening test. The anatomical continuity of the uterine cavity with the cervix makes the Papanicolaou (Pap) test accessible to evaluate signs of disease shed from the endometrium. Our aim was to determine the sensitivity of routine Pap test in endometrial carcinoma detection and its relationship with clinico-pathologic factors. We performed a systematic review of studies reporting Pap test results prior to diagnosis of or surgery for endometrial carcinoma between 1990 and 2018 in PubMed or Web of Science. Two independent reviewers extracted data and assessed study quality using an adapted Newcastle-Ottawa Quality Assessment Scale and Quality Assessment of Diagnostic Accuracy Studies tool. We identified 45 studies including a total of 6599 women with endometrial cancer. Abnormal Pap test results prior to diagnosis of or surgery for endometrial carcinoma were observed in 45% (95% CI, 40%-50%) of study participants. This percentage was significantly higher among those of non-endometrioid histology compared with endometrioid subtypes (77% [95% CI, 66%-87%] vs 44% [95% CI, 34%-53%], respectively; P heterogeneity <.001). Several clinico-pathologic factors were related to a higher percentage of abnormal Pap test results, including high-stage, myometrial invasion >50%, high histological grade, positive peritoneal cytology, presence of lymph node metastasis, cervical involvement, and lymphovascular invasion (P heterogeneity <.05 for all variables). Routine cervical cytology can detect endometrial cancer in almost half of patients, whereas sensitivity is higher among individuals with non-endometrioid histology or more advanced cancers. This review summarizes the current clinical and prognostic value of cervical cytology in endometrial carcinoma. Recent technological developments using molecular biomarkers may improve accuracy for early cancer detection., (© 2020 American Cancer Society.)

Due to the anatomical continuity of the uterine cavity with the cervix, genomic exploitation of material from routine Pap smears and other noninvasive sampling methods represent a unique opportunity to detect signs of disease using biological material shed from the upper genital tract. Recent research findings offer a promising perspective in the detection of endometrial cancer, but certain questions need to be addressed in order to accelerate the implementation of novel technologies in a routine screening or clinical setting. We discuss here new perspectives on detection of endometrial cancer using genomic and other biomarkers in minimally invasive sampling methods with a special focus on public health classic screening criteria, highlighting current gaps in knowledge., (© 2019 UICC.)

Introduction: The current availability of genomic information represents an opportunity to develop new strategies for early detection of cancer. New molecular tests for endometrial cancer may improve performance and failure rates of histological aspirate-based diagnosis, and provide promising perspectives for a potential screening scenario. However, the selection of relevant biomarkers to develop efficient strategies can be a challenge., Materials and Methods: We developed an algorithm to identify the largest number of patients with endometrial cancer using the minimum number of somatic mutations based on The Cancer Genome Atlas (TCGA) dataset., Results: The algorithm provided the number of subjects with mutations (sensitivity) for a given number of biomarkers included in the signature. For instance, by evaluating the 50 most representative point mutations, up to 81.9% of endometrial cancers can be identified in the TCGA dataset. At gene level, a 92.9% sensitivity can be obtained by interrogating five genes., Discussion: We developed a computational method to aid in the selection of relevant genomic biomarkers in endometrial cancer that can be adapted to other cancer types or diseases., (Copyright © 2019 Elsevier Ltd.
