Although adrenal incidentalomas have become a common indication for adrenalectomy, this has not resulted in patients with ACC being diagnosed earlier or treated at a lower stage of disease at the national level. The most important predictors of survival in these patients are tumor grade, tumor stage, and surgical resection.
If utilized in the appropriate patient population, a selective approach to lateral cervical LND for PTC can be a successful alternative to the routine modified radical LND. Levels I and V do not require resection unless there is clinical or radiological evidence of disease. Guidelines for which patients may be considered for this less aggressive approach to level II nodal metastases are suggested.
ECM1 and TMPRSS4 are excellent diagnostic markers of malignant thyroid nodules and may be used to improve the diagnostic accuracy of FNA biopsy. ECM1 is also a marker of the extent of disease in differentiated thyroid cancers.
Objective Evaluate patient choices and outcomes following positive cfDNA.Method Retrospective cohort study of women with positive cfDNA through two academic centers between March 2012 and December 2014. Patients were screened based on ACOG indications. Medical records reviewed for counseling, ultrasound findings, diagnostic testing, karyotype and outcome.Results CfDNA was positive in 114 women; 105 singletons and 9 twin pairs. CfDNA was positive for autosomal trisomy (21, 18, 13) in 96 (84.2%) and sex chromosome aneuploidy in 18 (15.8%). Certified genetic counselors performed 95% of post-cfDNA counseling. Prenatal diagnostic testing was pursued by 71/114 (62%). Karyotype was available in 91/105 (86.7%) singletons and confirmed aneuploidy in 75/91 (82.4%); the PPV of cfDNA with any ultrasound finding was 93.6% versus 58.6% without a finding. An abnormal sonographic finding was seen in 4/16 (25%) singletons with false positive cfDNA. Fetal termination occurred in 53/79 (67%) singletons and 3/5 (60%) twins with prenatal abnormal or unknown karyotype for autosomal trisomy. Eleven fetuses (11/56, 19.6%) were terminated for suspected autosomal trisomy without karyotype confirmation.Conclusion Patient choices following positive cfDNA are varied. Ultrasound modifies the PPV of cfDNA. Termination rates for aneuploidy are not higher than historical controls. Recommendation for karyotype confirmation prior to termination is not universally followed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
