AI Article Synopsis

  • Thyroid cancer negatively impacts quality of life (QOL) more than other cancers with worse prognoses, and the effects of indeterminate thyroid nodules on QOL were previously unexplored.
  • The study assessed patients with indeterminate biopsy results using a short Thyro-39 questionnaire, revealing that 44.4% of the 825 participants completed it, with notable findings on their symptoms.
  • Results showed that patients with benign molecular test results reported better QOL compared to those with suspicious results, particularly regarding symptoms of goiter and depression, indicating that benign results may help alleviate anxiety about malignancy.

Article Abstract

Objective: Thyroid cancer has a disproportionately negative effect on the quality of life (QOL) compared to malignancies with a worse prognosis. The QOL of patients with indeterminate thyroid nodules has not been previously evaluated. We aimed to assess the impact of molecular test results on the QOL of patients with indeterminate thyroid nodules.

Methods: A short version of the Thyroid-Related Patient-Reported Outcome (ThyPro-39) was used to assess the QOL of patients who underwent thyroid fine needle aspiration (FNA) biopsy throughout UCLA Health from May, 2016, to June, 2017. All patients with indeterminate biopsy results underwent molecular testing with either Afirma Gene Expression Classifier or ThyroSeq v2 at the time of the initial biopsy. The QOL associated with symptoms of goiter, anxiety, depression, and impaired daily life were analyzed.

Results: Of 825 consented patients, 366 completed the assessment (44.4% response rate). FNA results included 76% benign, 7% malignant, and 17% indeterminate. There were no differences in QOL between patients with a benign FNA and patients with an indeterminate result with benign molecular testing. In patients with an indeterminate FNA, symptoms of goiter (20.5 versus 10.4; P = .033) and depression (33.3 versus 21.0; P = .026) were worse for patients with suspicious versus benign molecular test results; however, no significant differences were observed in anxiety or impaired daily life.

Conclusion: A benign molecular test result may provide reassurance for patients with indeterminate thyroid nodules that the risk of malignancy is low. Long-term follow-up is necessary to determine if benign molecular test results maintain improved QOL.

Objective: Few prognostic analyses have been conducted for papillary thyroid cancer (PTC) patients with preablative stimulated Tg >10 ng/mL. We investigated the therapeutic responses and prognosis of these patients after the initial radioiodine (RAI) therapy.

Methods: We retrospectively assessed 256 patients with PTC who underwent RAI remnant ablation after total thyroidectomy, and all presTg levels were >10 ng/mL.

Aim: Both clonal hematopoiesis of indeterminate potential (CHIP) and type 2 diabetes mellitus (T2DM) are conditions closely associated with advancing age. This study delves into the possible implications and prognostic significance of CHIP and T2DM in patients diagnosed with ST-segment elevation myocardial infarction (STEMI).

Methods: Deep-targeted sequencing employing a unique molecular identifier (UMI) for the analysis of 42 CHIP mutations-achieving an impressive mean depth of coverage at 1000 × -was conducted on a cohort of 1430 patients diagnosed with acute myocardial infarction (473 patients with T2DM and 930 non-DM subjects).

Introduction: The rate of nondiagnostic and indeterminate cytology findings from fine-needle aspiration biopsy (FNAB) is quite high, resulting in repeated puncture and unnecessary surgery. The primary objective of this investigation is to compare diagnostic accuracy of core-needle biopsy (CNB) with repeat FNAB for thyroid nodules with initially inconclusive (nondiagnostic and/or atypia of undetermined significance) FNAB results.

Materials And Methods: A thorough search was performed on the Cochrane Library, Scopus, Europe PMC, and Medline databases until October 20th, 2024, employing a combination of pertinent keywords.

Background: This study aims to report the experience over 40 years and outcomes of 5070 patients who underwent a pelvic pouch procedure.

Methods: A retrospective analysis of a prospectively maintained IPAA database- (1983 - 2022) was performed. Patients were stratified based on the diagnosis: ulcerative colitis (UC), indeterminate colitis (IC), familial adenomatous polyposis (FAP), inflammatory bowel disease-dysplasia, Crohn's colitis (CD), and others.

Unlabelled: Many organizations recommend structured communication processes, including formal shared decision making (SDM), for patients undergoing lung cancer screening (LCS) using low-dose computed tomography (LDCT). We sought to understand if concordant and shared LCS decision making was associated with decisional conflict. In this prospective, observational study, we enrolled patients from 3 medical centers (2 Veterans Health Administration, 1 academic facility) after a decision-making interaction about undergoing LCS but before receiving the LDCT.
