RESUMEN

OBJECTIVE: Our aim was to evaluate the performance of different follow-up strategies after treatment for cervical intraepithelial neoplasia (CIN) 2 or 3, including human papillomavirus (HPV) detection, cytology, or colposcopy, as well as their combinations. Additionally, we compared the influence of the persistence of HPV 16/18 versus that of other high-risk HPV genotypes (HR-HPV) in the recurrence risk. METHODS: Retrospective register-based study, including women who had an excision of the transformation zone for CIN2 or CIN3 at our institution, between January 2011 and December 2022. The outcome assessed was histopathological recurrence/persistence of CIN2 or worse. RESULTS: Of the 721 women included, 6.8% (49/721) had recurrence/persistence. The sensitivity, specificity, and positive and negative predictive values of the HPV test were 97.4%, 80%, 22.3%, and 99.8%, respectively, whereas for cotesting (HR-HPV and cytology), 86.8%, 90.1%, 34.4%, and 99.1%, respectively. The referral rates for colposcopy were 24.3% and 14.2%, respectively. The sensitivity of colposcopy was low (40.0%).Women who were initially positive for non-16/18 genotypes at baseline who became HPV16/18 positive during follow-up, had a statistically significant increased risk of CIN2 or worse, compared with those who tested positive only for other HR-HPV genotypes during both stages (hazard ratio = 4.98; 95% CI = 1.66-14.91). CONCLUSIONS: Human papillomavirus testing is the best strategy for follow-up after treatment of cervical HSIL. The addition of cytology triage decreases by more than 40% the referrals for colposcopy, without significantly missing cases of recurrence/persistence. Human papillomavirus 16/18 in the follow-up, regardless of being previously positive, is associated with higher risk of recurrence/persistence of HSIL.

RESUMEN

INTRODUCTION: Cervical cancer is a major public health issue in Uganda, with high incidence due to limited screening especially in rural areas. In 2019, HPV DNA testing using GeneXpert was rolled out to improve screening access. Assessing progress and challenges since its introduction is important. AIM: To determine genotype distribution and explore health worker experiences with HPV screening using GeneXpert in Uganda. METHODS: We conducted a retrospective cohort study where HPV screening data from 66 GeneXpert labs from March 2021-May 2023 country wide was analyzed. We used descriptive statistics to provide percentages and proportions from the data. Seven focus group discussions and five interviews were done with health workers to understand experiences. RESULTS: We extracted 24,497 HPV tests that were done, and 39.1% were HPV positive. Other high-risk HPV genotypes were the most common at 65%, followed by HPV 16 (17%) and HPV 18/45 (18%). 15% of the HPV positive cases had more than one genotype. Qualitative findings showed inconsistent health worker knowledge, high workload, and complex care seeking behaviors as main challenges. It also revealed low community awareness, care seeking from traditional healers, CONCLUSION: HPV DNA testing has been expanding since its rollout, but the yield of HPV cases is lower than expected, signaling need to address supply-side challenges. Limited information on HPV among health workers especially community health workers, demand-side barriers like myths, medical pluralism and social norms must also be tackled through trainings of health workers and awareness campaigns engaging communities. Although access to GeneXpert services has increased, health system weaknesses pose bottlenecks to screening HPV. Targeted interventions are required to strengthen HPV diagnosis, prevent cervical cancer and save lives.

RESUMEN

HPV16, with typical mutations that differ in geographical distribution and carcinogenic potency, has implications for cervical cancer screening, clinical diagnosis, and treatment. DNASTAR and MEGA were used to identify HPV16 variants and construct a phylogenetic tree. The most prevalent HPV genotypes were HPV16 (63.9%), HPV18 (26.7%), and other HPV (6.9%). HPV16 alterations were found in all E6, E7, and L1 genes, including 15 missense and 18 synonymous mutations. Missense mutations include R10G, Q14H, D25E, H78Y, L83V (E6); M29V, R35K, L78R, L95P (E7); H73Y, T176 N, N178T, T317P, T386S, L472F/I (L1). HPV16 sublineages include A1 (17.2%), A2 (0.9%), A3 (56.0%), A4 (19.0%), D1 (4.3%), and D3 (2.6%). Although several mutations in the oncoproteins E6, E7, and L1 have been detected, mutations known to be associated with cervical cancer risk, such as D25E and L83V, occur at a relatively low frequency. This suggests that HPV16 mutations are associated with cervical cancer through a complicated mechanism.

RESUMEN

BACKGROUND: Lung cancer screening (LCS) using low-dose computed tomography (LDCT) reduces lung cancer mortality but can lead to downstream procedures, complications, and other potential harms. Estimates of these events outside NLST (National Lung Screening Trial) have been variable and lacked evaluation by screening result, which allows more direct comparison with trials. OBJECTIVE: To identify rates of downstream procedures and complications associated with LCS. DESIGN: Retrospective cohort study. SETTING: 5 U.S. health care systems. PATIENTS: Individuals who completed a baseline LDCT scan for LCS between 2014 and 2018. MEASUREMENTS: Outcomes included downstream imaging, invasive diagnostic procedures, and procedural complications. For each, absolute rates were calculated overall and stratified by screening result and by lung cancer detection, and positive and negative predictive values were calculated. RESULTS: Among the 9266 screened patients, 1472 (15.9%) had a baseline LDCT scan showing abnormalities, of whom 140 (9.5%) were diagnosed with lung cancer within 12 months (positive predictive value, 9.5% [95% CI, 8.0% to 11.0%]; negative predictive value, 99.8% [CI, 99.7% to 99.9%]; sensitivity, 92.7% [CI, 88.6% to 96.9%]; specificity, 84.4% [CI, 83.7% to 85.2%]). Absolute rates of downstream imaging and invasive procedures in screened patients were 31.9% and 2.8%, respectively. In patients undergoing invasive procedures after abnormal findings, complication rates were substantially higher than those in NLST (30.6% vs. 17.7% for any complication; 20.6% vs. 9.4% for major complications). LIMITATION: Assessment of outcomes was retrospective and was based on procedural coding. CONCLUSION: The results indicate substantially higher rates of downstream procedures and complications associated with LCS in practice than observed in NLST. Diagnostic management likely needs to be assessed and improved to ensure that screening benefits outweigh potential harms.

RESUMEN

INTRODUCTION: In the absence of evidence on the effect of mammographic screening on overall mortality, comparing the number of deaths avoided with the number of deaths caused by screening would be ideal, but the only existing models of this type adopt a very narrow definition of harms. The objective of the present study was to estimate the number of deaths prevented and induced by various mammography screening protocols in Brazil. METHODS: A simulation study of cohorts of Brazilian women screened, considering various age groups and screening interval protocols, was performed based on life tables. The number of deaths avoided and caused by screening was estimated, as was the absolute risk reduction, the number needed to invite for screening-NNS, the net benefit of screening, and the ratio of "lives saved" to "lives lost". Nine possible combinations of balances between benefits and harms were performed for each protocol, in addition to other sensitivity analyses. RESULTS AND CONCLUSIONS: The most efficient protocol was biennial screening from 60 to 69 years of age, with almost three times more deaths avoided than biennial screening from 50 to 59 years of age, with a similar number of deaths avoided by biennial screening from 50 to 69 years of age and with the greatest net benefit. Compared with the best scenario of annual screening from 40 to 49 years of age, the NNS of the protocol with biennial screening from 60 to 69 years of age was three-fold lower. Even in its best scenario, the addition of annual screening from 40 to 49 years of age to biennial screening from 50 to 69 years of age results in a decreased net benefit. However, even in the 50-69 year age group, the estimated reduction in breast cancer mortality for Brazil was half that estimated for the United Kingdom.

RESUMEN

INTRODUCTION: Older adults with cancer who are being considered for cancer surgery are heterogenous, with variation in their physical, mental, and social baselines and risk of postoperative complications. Due in part to the complex nature of this population, the optimal preoperative evaluation method is not clearly defined. In this study we investigated whether geriatric-8 (G8), a screening tool for older patients with cancer that determines the need for a full geriatric assessment, is suitable for assessing the risk of postoperative complications in this population being considered for surgery. MATERIALS AND METHODS: Studies that enrolled older patients undergoing cancer surgery and compared prevalence of postoperative complications in G8 "high" (≥15) patients and G8 "low" (<15) patients were identified using PubMed and EMBASE. A meta-analysis was conducted to calculate the risk ratio of postoperative complication rate. Postoperative mortality was systematically reviewed. RESULTS: Eleven studies published between 2017 and 2022 were included in our analysis with a total of 2,691 older patients who underwent various types of cancer surgery and were characterized by their G8 scores: 1,255 G8 high (≥15) patients and 1,436 G8 low (<15) patients. G8 low patients had a significantly higher prevalence of postoperative complications than G8 high patients (risk ratio [95% confidence interval]: 1.56 [1.18-2.07], p = 0.002, I2 = 79%). DISCUSSION: G8 can be an effective and efficient preoperative tool to assess risk of postoperative complications in older adults undergoing cancer surgery and identify potential need for further evaluation of an individual's risk with a comprehensive geriatric assessment.

RESUMEN

INTRODUCTION: The etiological assessment after an acute unprovoked pulmonary embolism (PE) represents an essential step in the overall management of the patient, with the aim of adapting the duration and type of anticoagulant to be used, avoiding recurrence and thus improving overall morbidity and mortality, but this is not such a simple question to answer. PURPOSE: The main objective of this work is to know the benefit of a limited etiology strategy versus an extensive strategy after a first episode of acute non-provoked PE, first on all-cause mortality, and then the superiority of one strategy over another on the diagnosis of cancer at 1 year in patients admitted to a cardiac intensive care unit. METHODS: This is a single-center, retrospective study from 2014 to 2021, which includes all patients, admitted to a cardiac intensive care unit for a first episode, at high or high intermediate risk of mortality at day 30. The included patients were divided into 2 groups: those who received a limited cancer screening strategy, and those who received, in addition to the latter, an injected cerebral and cervical-thoracic-abdominal scan, and the determination of tumor markers. All data were extracted from the medical hospital files. RESULTS: In total, we included 130 patients. The mean age of our patients was 87.19 (SD = 6.1), with a female predominance with a percentage of 55.4%. Eighty-seven patients benefited from an extensive cancer screening strategy, versus 43 patients who benefited from a limited strategy. First, for mortality at 1 year, 27 deaths were found between the 2 groups but without significant difference (hazard ratio; 0.53; P = 0.16), and for the mean duration from embolic episode to death, there was a mean of 20 weeks for the limited strategy group and 24 weeks for the extensive strategy group, with a nonsignificant difference ( P = 0.106). For the diagnosis of cancer at 1 year, 28 patients were diagnosed with cancer: 13 patients in the limited strategy group versus 15 in the extensive strategy group, with no significant difference (hazard ratio, 1.983; P = 0.082). The mean time to diagnosis was 22 weeks in the limited strategy group and 20 weeks in the extensive strategy, with no significant difference ( P = 0.729). CONCLUSION: To date, no scientific evidence has been established for the extensive versus the limited strategy, therefore, a minimal etiological workup is also effective in the detection of cancer after unprovoked PE.

RESUMEN

Current US lung cancer screening recommendations limit eligibility to adults with a pack-year (PY) history of ≥20 years and the first 15 years since quit (YSQ). The authors conducted a systematic review to better understand lung cancer incidence, risk and mortality among otherwise eligible individuals in this population beyond 15 YSQ. The PubMed and Scopus databases were searched through February 14, 2023, and relevant articles were searched by hand. Included studies examined the relationship between adults with both a ≥20-PY history and ≥15 YSQ and lung cancer diagnosis, mortality, and screening ineligibility. One investigator abstracted data and a second confirmed. Two investigators independently assessed study quality and certainty of evidence (COE) and resolved discordance through consensus. From 2636 titles, 22 studies in 26 articles were included. Three studies provided low COE of elevated lung cancer incidence beyond 15 YSQ, as compared with people who never smoked, and six studies provided moderate COE that the risk of a lung cancer diagnosis after 15 YSQ declines gradually, but with no clinically significant difference just before and after 15 YSQ. Studies examining lung cancer-related disparities suggest that outcomes after 15 YSQ were similar between African American/Black and White participants; increasing YSQ would expand eligibility for African American/Black individuals, but for a significantly larger proportion of White individuals. The authors observed that the risk of lung cancer not only persists beyond 15 YSQ but that, compared with individuals who never smoked, the risk may remain significantly elevated for 2 or 3 decades. Future research of nationally representative samples with consistent reporting across studies is needed, as are better data from which to examine the effects on health disparities across different populations.

RESUMEN

BACKGROUND: Guidelines recommend shared decision-making (SDM) around mammography screening for women ≥ 75 years old. OBJECTIVE: To use microsimulation modeling to estimate the lifetime benefits and harms of screening women aged 75, 80, and 85 years based on their individual risk factors (family history, breast density, prior biopsy) and comorbidity level to support SDM in clinical practice. DESIGN, SETTING, AND PARTICIPANTS: We adapted two established Cancer Intervention and Surveillance Modeling Network (CISNET) models to evaluate the remaining lifetime benefits and harms of screening U.S. women born in 1940, at decision ages 75, 80, and 85 years considering their individual risk factors and comorbidity levels. Results were summarized for average- and higher-risk women (defined as having breast cancer family history, heterogeneously dense breasts, and no prior biopsy, 5% of the population). MAIN OUTCOMES AND MEASURES: Remaining lifetime breast cancers detected, deaths (breast cancer/other causes), false positives, and overdiagnoses for average- and higher-risk women by age and comorbidity level for screening (one or five screens) vs. no screening per 1000 women. RESULTS: Compared to stopping, one additional screen at 75 years old resulted in six and eight more breast cancers detected (10% overdiagnoses), one and two fewer breast cancer deaths, and 52 and 59 false positives per 1000 average- and higher-risk women without comorbidities, respectively. Five additional screens over 10 years led to 23 and 31 additional breast cancer cases (29-31% overdiagnoses), four and 15 breast cancer deaths avoided, and 238 and 268 false positives per 1000 average- and higher-risk screened women without comorbidities, respectively. Screening women at older ages (80 and 85 years old) and high comorbidity levels led to fewer breast cancer deaths and a higher percentage of overdiagnoses. CONCLUSIONS: Simulation models show that continuing screening in women ≥ 75 years old results in fewer breast cancer deaths but more false positive tests and overdiagnoses. Together, clinicians and 75 + women may use model output to weigh the benefits and harms of continued screening.

RESUMEN

BACKGROUND: There is little evidence on the balance between potential benefits and harms of mammography screening in women 75 years and older. The aim of this systematic review was to synthesise the evidence on the outcomes of mammography screening in women aged 75 years and older. METHODS: A systematic review of mammography screening studies in women aged 75 years and over. RESULTS: Thirty-six studies were included in this review: 27 observational studies and 9 modelling studies. Many of the included studies used no or uninformative comparison groups resulting in a potential bias towards the benefits of screening. Despite this, there was mixed evidence about the benefits and harms of continuing mammography screening beyond the age of 75 years. Some studies showed a beneficial effect on breast cancer mortality, and other studies showed no effect on mortality. Some studies showed some harms (false positive tests and recalls) being comparable to those in younger age-groups, with other studies showing increase in false positive screens and biopsies in older age-group. Although reported in fewer studies, there was consistent evidence of increased overdiagnosis in older age-groups. CONCLUSION: There is limited evidence available to make a recommendation for/against continuing breast screening beyond the age of 75 years. Future studies should use more informative comparisons and should estimate overdiagnosis given potentially substantial harm in this age-group due to competing causes of death. This review was prospectively registered with PROSPERO (CRD42020203131).

RESUMEN

Human papillomavirus (HPV) is a DNA oncogenic virus. HPV infection is the most common sexually transmitted disease, and is capable of infecting mucosal and cutaneous membranes of the anogenital, upper aerodigestive tract, and other head and neck mucosal regions. Although HPV infection is generally asymptomatic and can be easily resolved by the immune system, if it persists and progresses, it can lead to cancer. HPV is permanently responsible for 5% of human cancers. Malignant lesions related to HPV include oral and respiratory squamous cell carcinomas, and cervical and anogenital cancers. Currently, no specific treatment is available for HPV infection, and therapeutic procedures (tissue ablation, chemotherapy, cryotherapy, and immunomodulation) cannot eliminate the virus completely. Vaccination and cervical screening are two methods that have been developed to provide protection against oncogenic HPV. Unfortunately, no effective protocol for vaccination, prevention, testing, or treatment has yet been proposed in the developing countries. In this review, we have reviewed the knowledge gained from recent studies on virology, pathogenesis, clinical manifestations, epidemiology, prevention, and treatment of HPV infection.

RESUMEN

Childhood and young adult survivors of Hodgkin lymphoma are at an elevated risk of developing breast cancer. Breast cancer risk is felt to originate from chest wall radiation exposure prior to the third decade of life, with incidence beginning to rise approximately eight to ten years following Hodgkin lymphoma treatment. Although incidence varies according to age at radiation exposure, dosage, and treatment fields, cohort studies have documented a cumulative incidence of breast cancer of 10-20% by 40 years of age. Women with a history of chest radiation for Hodgkin lymphoma are counselled to begin screening with bilateral breast MRI at 25 years of age, or eight years after radiation, whichever occurs later. Outside of high-risk surveillance, the optimal management approach for women with prior radiation exposure continues to evolve. When diagnosed with breast malignancy, evidence supports consideration of unilateral therapeutic and contralateral prophylactic mastectomy, although breast conserving surgery may be considered following multidisciplinary assessment. This review will address the epidemiology, characteristics, screening and management guidelines, and breast-cancer prevention efforts for Hodgkin lymphoma survivors treated with radiation therapy in adolescence and young adulthood.

RESUMEN

Breast cancer is the most common cancer among U.S. women and its incidence increases with age. Endogenous estrogen exposure, proliferative benign breast disease, breast density, and family history may also indicate increased risk for breast cancer. Early detection with screening mammography reduces breast cancer mortality, but the net benefits vary by age. Assessing a patient's individual breast cancer risk can guide decisions regarding breast cancer screening. All women benefit from healthy behaviors which may reduce breast cancer risk. Some women at increased risk for breast cancer may benefit from risk-reducing medications. Use of screening measures remains suboptimal, especially for uninsured women.

RESUMEN

OBJECTIVE: This study aimed to assess the incidence of early cancer therapy-related cardiac dysfunction (CTRCD) and the characteristics of left and right heart deformations during anthracycline chemotherapy. METHODS: We prospectively enrolled a cohort of 351 chemotherapy-naïve women with breast cancer and cardiovascular risk factors who were scheduled to receive anthracycline. The left ventricular ejection fraction (LVEF), left ventricular global longitudinal strain (LV-GLS) and right ventricular and left atrial longitudinal strains were evaluated using echocardiography at baseline, before every subsequent cycles and at 3 weeks after the final anthracycline dose. CTRCD was defined as a new LVEF reduction by ≥10 percentage points to an LVEF<50% and/or a new relative decline in GLS by >15% from the baseline value. RESULTS: Eighteen (5.1%) patients had evidence of asymptomatic CTRCD during anthracycline treatment, and 50% developed CTRCD before completing the chemotherapy regimen. In the CTRCD group, while LV-GLS decrease significantly after the first dose of anthracycline, the reduction of right ventricular free-wall longitudinal strain and left atrial reservoir strain were observed after the second dose. Other strain indices could not be used to identify early CTRCD. CONCLUSIONS: Cardiotoxicity appeared soon after the initiation of anthracycline chemotherapy. Among the left-heart and right-heart mechanics, LV-GLS remains the best deformation indicator for detecting early CTRCD.

RESUMEN

BACKGROUND: Oesophageal cancer has significant morbidity and mortality but late diagnosis is common since early signs of disease are frequently misinterpreted. Project DELTA aims to enable earlier detection and treatment through targeted screening using a novel risk prediction algorithm for oesophageal cancer (incorporating risk factors of Barrett's oesophagus including prescriptions for acid-reducing medications (CanPredict)), together with a non-invasive, low-cost sampling device (CytospongeTM). However, there are many barriers to implementation, and this paper identifies key ethical and legal challenges to implementing these personalised prevention strategies for Barrett's oesophagus/oesophageal cancer. METHODS: To identify ethical and legal issues relevant to the deployment of a risk prediction tool for oesophageal cancer into primary care, we adopted an interdisciplinary approach, incorporating targeted informal literature reviews, interviews with expert collaborators, a multidisciplinary workshop and ethical and legal analysis. RESULTS: Successful implementation raises many issues including ensuring transparency and effective risk communication; addressing bias and inequity; managing resources appropriately and avoiding exceptionalism. Clinicians will need support and training to use cancer risk prediction algorithms, ensuring that they understand how risk algorithms supplement rather than replace medical decision-making. Workshop participants had concerns about liability for harms arising from risk algorithms, including from potential bias and inequitable implementation. Determining strategies for risk communication enabling transparency but avoiding exceptionalist approaches are a significant challenge. Future challenges include using artificial intelligence to bolster risk assessment, incorporating genomics into risk tools, and deployment by non-health professional users. However, these strategies could improve detection and outcomes. CONCLUSIONS: Novel pathways incorporating risk prediction algorithms hold considerable promise, especially when combined with low-cost sampling. However immediate priorities should be to develop risk communication strategies that take account of using validated risk algorithms, and to ensure equitable implementation. Resolving questions about liability for harms arising should be a longer-term objective.

RESUMEN

BACKGROUND & AIMS: Worldwide, hepatocellular carcinoma (HCC) is a common malignancy. We aimed to prospectively determine the incidence and risk factors of HCC in a U.S. METHODS: The multicenter Hepatocellular Carcinoma Early Detection Strategy study of the National Institutes of Health prospectively enrolled patients with cirrhosis who underwent standard surveillance for HCC. Demographics, medical and family history, etiology of liver disease, and clinical features were evaluated for associations with HCC. RESULTS: Between April 10, 2013 and December 31, 2021, 1723 patients were enrolled and confirmed eligible. During median follow-up of 2.2 years (range, 0-8.7 years), there were 109 incident cases of HCC for an incidence rate of 2.4 per 100 person-years: 88 (81%) patients with very early/early Barcelona Clinic Liver Cancer stage (0, A), 20 (18%) intermediate stage (B), and 1 (1%) unknown stage. Risk factor analyses were restricted to 1325 patients, including 95 incident HCC, with at least 6 months of follow-up. The majority were men (53.2%), obese or severely obese (median body mass index, 30.2 kg/m2), and white (86.3%); 42.0% had history of hepatitis C virus infection, 20.7% had alcoholic liver disease, and 24.9% had nonalcoholic fatty liver disease. Fourteen risk factors for HCC were significant (P < .05) in univariate analyses, and a multivariate subset was selected using stepwise logistic regression. The multivariate subset contained gender (P < .001; male; odds ratio [OR], 2.47; 95% confidence interval [CI], 1.54-4.07), years with cirrhosis (P = .004; OR, 1.06; 95% CI, 1.02-1.1), family history of liver cancer (P = .02; yes; OR, 2.69; 95% CI, 1.11-5.86), age (per 5 years; P = .02; OR, 1.17; 95% CI, 1.03-1.33), obesity (P = .02; yes; OR, 1.7; 95% CI, 1.08-2.73), aspartate aminotransferase (log(1+AST); P = .06; OR, 1.54; 95% CI, 0.97-2.42), alpha-fetoprotein (log(1+AFP); P = .07; OR, 1.32; 95% CI, 0.97-1.77), and albumin (P = .10; OR, 0.7; 95% CI, 0.46-1.07). CONCLUSIONS: Thus far, this is the largest prospective and geographically diverse study of a U.S. cohort of patients with cirrhosis that validates known risk factors for HCC (gender, age, obesity, years with cirrhosis, family history of liver cancer, baseline AFP, albumin, and AST). The incidence of HCC was 2.4% per 100 person-years.

RESUMEN

Cancer and cardiovascular diseases (CVD) often share common risk factors, and patients with CVD who develop cancer are at high risk of experiencing major adverse cardiovascular events. Additionally, cancer treatment can induce short- and long-term adverse cardiovascular events. Given the improvement in oncological patients' prognosis, the burden in this vulnerable population is slowly shifting towards increased cardiovascular mortality. Consequently, the field of cardio-oncology is steadily expanding, prompting the need for new markers to stratify and monitor the cardiovascular risk in oncological patients before, during, and after the completion of treatment. Advanced non-invasive cardiac imaging has raised great interest in the early detection of CVD and cardiotoxicity in oncological patients. Nuclear medicine has long been a pivotal exam to robustly assess and monitor the cardiac function of patients undergoing potentially cardiotoxic chemotherapies. In addition, recent radiotracers have shown great interest in the early detection of cancer-treatment-related cardiotoxicity. In this review, we summarize the current and emerging nuclear cardiology tools that can help identify cardiotoxicity and assess the cardiovascular risk in patients undergoing cancer treatments and discuss the specific role of nuclear cardiology alongside other non-invasive imaging techniques.

RESUMEN

Importance: Cervical cancer screening is associated with reduced cervical cancer mortality; however, clinical trials have also shown an association between excisional procedures for cervical neoplasia and an increased risk of preterm delivery (PTD). National screening guidelines must weigh adverse effects on birth outcomes against benefits of cancer prevention. Objective: To ascertain the population-level association between the number of guideline-recommended cervical cancer screenings and downstream PTD risk among females aged 18 to 24 years. Design, Setting, and Participants: This cross-sectional study used a difference-in-differences approach based on variation in the recommended number of cervical cancer screenings (over time and across individuals giving birth at different ages) to estimate the association between the cumulative recommended number of screenings (by the time of childbirth) and PTD risk. National Vital Statistics System data from females aged 18 to 24 years who had a singleton, nulliparous birth in the US between 1996 and 2018 were used. Regression models were adjusted for maternal educational level, race and ethnicity, comorbidities, marital status, and prenatal care visits. Data were analyzed between June 2020 and March 2023. Exposure: A constructed variable capturing the cumulative number of guideline-recommended cervical cancer screenings for an individual based on their age and year of childbirth. Main Outcomes and Measures: Binary indicators for PTD and very preterm delivery (VPTD), defined as delivery before 37 and 34 weeks' gestational age, respectively, and gestational age was measured in weeks from the first day of the last menstrual period. Results: Among 11 333 151 females aged 18 to 24 years who gave birth between 1996 and 2018, 2 069 713 were Black (18.3%), 2 601 225 were Hispanic (23.0%), 6 068 498 were White (53.5%) individuals, and 593 715 (5.2%) were individuals of other race or ethnicity (Alaska Native; American Indian; Asian; Pacific Islander; multiracial; or unknown or missing race or ethnicity). Mean (SD) age was 20.9 (1.9) years, and 766 001 individuals (6.8%) had hypertension or diabetes. The mean (SD) number of guideline-recommended screenings by time of childbirth was 2.4 (2.2). Overall, PTD and VPTD occurred in 1 140 490 individuals (10.1%) and 333 040 (2.9%) of births, respectively. One additional recommended screening was associated with a 0.073 (95% CI, 0.026-0.120) percentage-point increase in PTD risk but no statistically significant change in VPTD risk. Females with hypertension or diabetes had a higher increase in PTD risk than those without these comorbidities (0.26 [95% CI, 0.11-0.4] vs 0.06 [95% CI, 0.01-0.10] percentage points; Wald test P < .001). Conclusions and Relevance: Findings of this cross-sectional study suggest that additional recommended cervical cancer screenings before birth were associated with an increased risk of PTD. These results can be used in future simulation models integrating oncological trade-offs to help ascertain optimal screening strategies.
