3-year surveillance, 5-year return to regular screening) 3. In addition, the risks for some rare combinations could not be estimated with confidence. We will illustrate how risk estimates are used to determine management using hypothetical patient examples. J Low Genit Tract Dis 2020;24:102–31. Her colposcopic biopsy shows CIN 1. Scenario 4 describes management after a colposcopy at which CIN 2+ was not found (i.e., colposcopy/biopsy results were CIN 1 or normal). For immediate risks greater than 4%, the recommended management is determined by the immediate CIN 3+ risk. Colposcopy performed for low-grade abnormalities, which confirms the absence of CIN 2+ reduces risk. We used prevalence-incidence mixture models.8–10 The model is a mixture of logistic regression for events present at the time of the current visit (prevalent disease) and proportional hazards model for events occurring after the current visit (incident disease). and N.W.) Table 1A addresses patients without a documented recent HPV test result. risk-based; management guidelines; cervical screening; HPV. following colposcopy/biopsy finding less than CIN 2 (no treatment), Follow-up after Demarco M, Egemen D, Raine-Bennett TR, et al.

It addresses the need for simplicity and stability in clinical guidelines while anticipating continued technologic advances in cervical screening methods. She presents for follow-up at 1 year and her cotest result is HPV-positive ASC-US. NSQIP Risk Calculator . Implementing the 2019 ASCCP Risk Based Management Guidelines for Abnormal Cervical Cancer Screening Tests in Your Practice Patty Cason, MS, FNP-BC Envision Sexual and Reproductive . It is important to emphasize that for a given patient over time, a clinician is likely to consult various tables as the management scenarios are encountered, from initial abnormality to resolution. Therefore, the 2019 guidelines recommend referral for colposcopy for abnormal results occurring on subsequent rounds of follow-up testing. Basically, the heart attack can be predicted using this calculator. New data indicate that a patient's risk of developing cervical precancer or cancer can be estimated using current screening test results and previous screening test and biopsy results, while considering personal factor… Generalizability to other clinical settings/populations is thought to be good, as outlined in the methods article.3 Nonetheless, the recommendation confidence score should not be misinterpreted as the true probability that a recommendation is absolutely correct. At a population level, the risk of CIN 3+ for screening participants at any given age is highest at the time of the initial HPV-based screen (0.45% immediate CIN 3+ risk for patients new to HPV testing in KPNC aged 25–65 years). Therefore, patients with a negative cytology history will still be managed by Table 1A. Patient 7: A 32-year-old woman has a history of CIN 3 that was treated with diagnostic loop electrosurgical excisional procedure (LEEP), followed by 1 negative HPV test. The calculator keeps a check on the functioning of your heart. (2020) 2019 ASCCP Risk-Based Management Consensus Guidelines … has received HPV tests and assays at a reduced or no cost from Roche, Becton Dickinson, Arbor Vita Corporation, and Cepheid for research. The accumulation of individuals in the 30- to 34-year age group reflects the start of cotesting at 30 years and older from 2003 until KPNC guidelines changed in 2013 to recommend beginning cotesting at age 25 years. We estimated immediate and 5-year risks of CIN 3+ for combinations of current test results paired with history of screening test and colposcopy/biopsy results. The 2019 American Society for Colposcopy and Cervical Pathology (ASCCP) Risk-Based Management Consensus Guidelines describe 6 clinical actions that providers can use when managing patients with abnormal cervical cancer screening test results: treatment; optional treatment or colposcopy/biopsy; colposcopy/biopsy; 1-year surveillance; 3-year surveillance; and return to 5-year regular screening.1 These clinical actions are recommended based on a patient's risk of either currently having or subsequently developing cervical intraepithelial neoplasia grade 3 (CIN 3), adenocarcinoma in-situ (AIS), or cancer (defined subsequently as CIN 3+). The risk-based management tables shown in abbreviated form in this article underlie the 2019 ASCCP Risk-Based Consensus Management Guidelines. The recommended management is colposcopy because her immediate estimated risk is greater than 4% (the colposcopy threshold) and less than 25% (the treatment or colposcopy threshold). She presents for follow-up and her second HPV test result is also negative. 2019 ASCCP risk-based management consensus guidelines for abnormal Perkins RB, Guido RS, Castle PE, et al. For instance, a “Recommendation confidence score” of 95% for a recommendation of 1-year surveillance means 95% statistical confidence that the recommended management is correct when considering the KPNC data, rather than colposcopy or 3-year surveillance. This patient's immediate CIN 3+ risk is less than 4%, so the 5-year risk is used to determine the recommended management. We estimated risk of CIN 3+ at years 0, 1, 2, 3, 4, and 5; most decisions considered the immediate risks at year 0 and the 5-year risks (see Figure 2 and Cheung et al. A negative cotest after HPV-negative ASC-US warrants return to screening at 5-year intervals (5-year CIN 3+ risk is 0.14%, which is less than the 0.15% 5-year surveillance threshold). J Low Genit Tract Dis 2020;24:132-43. Determining suggested management based on calculated risk. Perkins RB, Guido RS, Castle PE, et al. to Egemen et al.) This patient has a history of treated CIN 3, therefore consult Table 5A. In the KPNC database, 290 women had this result combination, among whom 21 had CIN 3+, leading to a recommendation confidence score of 86%. leftmost column presents the oldest test result in the screening J Low Genit Tract Dis 2020;24:144–7. Although we had high statistical confidence in most of our estimates, the measure “Recommendation confidence score” is given more as a warning when the percentage is low, signifying lack of confidence in the recommendation because of data limitations (lack of observations or small number of observed cases). Surgical consultations can require patients to deal with difficult and complex information, provoking anxiety that diminishes their ability to process information or recall vital details. presented with its corresponding standard error (SE) and 95% lower (LL95) result as a percentage (%) of total screened, the total number of patients informative in risk estimation (N Egemen D, Cheung LC, Chen X, et al. Each risk estimate is The QRISK ® 3 algorithm calculates a person's risk of developing a heart attack or stroke over the next 10 years. 2019 ASCCP Risk-Based Management Consensus Guidelines for abnormal cervical cancer screening tests and cancer precursors. The 2019 guidelines comprehensively use and expand upon the principle of “equal management for equal risks” that was introduced in the 2012 guidelines.2 Specifically, management is based on a patient's risk of CIN 3+, regardless of what combination of test results yields that risk level. Demographics. Patient 3: A 32-year-old woman presents for follow-up. Castle PE, Kinney WK, Cheung LC, et al. NSQIP Risk Calculator. By continuing to use this website you are giving consent to cookies being used. Exploration of numerous potential risk factors led to the determination that a patient's CIN 3+ risk can be estimated based on current human papillomavirus (HPV) and cytology test results and recent history of test results, colposcopic evaluation and biopsy results, and treatments. has received cervical screening results at reduced or no cost from commercial research partners (Qiagen, Roche, BD, MobileODT, Arbor Vita) for independent evaluations of screening methods and strategies. All registration fields are required. A high percent suggests statistical precision, defined as adequate numbers of CIN 3+ events to generate a stable risk estimate and confidence that the estimate is yielding the correct recommendation based on the KPNC data. While they are evolutionary, Among the 8% of the population that initially tested HPV positive, immediate CIN 3+ risks ranged from 2.1% for HPV-positive NILM (below the colposcopy threshold), to 4.3% and 4.4% for HPV-positive ASC-US and LSIL, respectively (defining the colposcopy threshold), to 25% and 26% for HPV-negative HSIL+ and HPV-positive ASC-H, respectively (defining the treatment or colposcopy threshold), to 49% for HPV-positive HSIL+. following results not requiring immediate colposcopic referral, Receipt Risk calculation can be achieved by using a mobile phone App or a free web-based risk calculator available on the ASCCP website, as well as by referring to the tables published in Engemen et al. An HPV-negative test is virtually as reassuring as a negative cotest. The “current results” are those for which the clinician is seeking guidance, either an HPV test or cotest result (see Tables 1A–2C4A–5B) or a colposcopy/biopsy result (see Table 3).
