AI Article Synopsis

  • The study investigates the effectiveness of frozen biopsy in diagnosing central neck metastasis in patients with papillary thyroid cancer (PTC).
  • Approximately 53% of the 252 patients studied showed central neck metastasis, with frozen biopsy demonstrating a high sensitivity (92%) and specificity (99%) for detecting it.
  • The results indicate that frozen biopsy is a reliable method for accurately determining the number of metastatic lymph nodes during surgery, with a diagnostic accuracy of 91% compared to traditional permanent biopsy.

Article Abstract

Background: Nodal metastasis in papillary thyroid cancer (PTC) usually occurs in the central compartment of the ipsilateral neck and spreads laterally. The purpose of this study was to evaluate the diagnostic accuracy of frozen biopsy for quantitative nodal evaluation of central neck metastasis in PTC.

Methods: In all, 252 patients with PTC underwent total thyroidectomy with bilateral central neck dissection (CND). All tissues from ipsilateral CND were examined by frozen biopsy.

Results: Among them, 53% of patients had central neck metastasis. The sensitivity and specificity of frozen biopsy for central neck metastasis were 92% and 99%, respectively. The positive predictive value and the negative predictive value were 99% and 84%, respectively. The diagnostic accuracy for the exact number of metastatic nodes was 91% compared to permanent biopsy.

Conclusions: Frozen biopsy for quantitative analysis of central compartment is a useful tool for the precise evaluation of central lymphatic status intraoperatively with a high sensitivity and specificity.

Management of thyroid nodules with atypia of undetermined significance/follicular lesion of undetermined significance (AUS/FLUS) cytology is challenging because of uncertain malignancy risk. Intraoperative frozen section pathology provides real-time diagnosis for AUS/FLUS nodules undergoing surgery, but its accuracy is limited. This study aimed to develop an integrated predictive model combining clinical, ultrasound and IOFS features to improve intraoperative malignancy risk assessment.

With advanced mass spectrometry (MS)-based proteomics, genome-scale proteome coverage can be achieved from bulk tissues. However, such bulk measurement lacks spatial resolution and obscures tissue heterogeneity, precluding proteome mapping of tissue microenvironment. Here we report an integrated wet collection of single microscale tissue voxels and Surfactant-assisted One-Pot voxel processing method termed wcSOP for robust label-free single voxel proteomics.

Introduction: EUS-guided fine-needle organoid creation (EUS-FNO) from pancreatic cancer (PC) has been increasingly important for precision medicine. The cost for pancreatic organoid creation is substantial and close to 2000 USD/specimen in our institution, and the specimen has to be processed immediately after tissue acquisition so the more passes and specimens, the higher cost of organoid creation will incur. To date, no prospective comparison trial has answered how many needle passes of EUS-FNO needed for a successful organoid creation.
