There has been a persistent demand for an innovative modality in real-time histologic imaging, distinct from the conventional frozen section technique. We developed an artificial intelligence-driven real-time evaluation model for gastric cancer tissue using confocal laser endomicroscopic system. The remarkable performance of the model suggests its potential utilization as a standalone modality for instantaneous histologic assessment and as a complementary tool for pathologists' interpretation.

A peritumoral lymphoid cuff is frequently seen in GI tract schwannomas and correlates well with regional lymphadenopathy. However, in a significant subset (29.7%), a lymphoid cuff was not present warranting continued need for caution in the preoperative radiologic and postoperative pathologic diagnoses.

Tumor multiplicity has prognostic value and could be used to subclassify invasive breast cancer at early stages. Adjuvant chemotherapy would be necessary for multiple masses of T1-2 N0 M0, hormone-receptor-positive, and HER2-negative cancer.

PNLH is an uncommon but distinct entity with a benign nature, and understanding the radiological and clinicopathological characteristics of PNLH is important.

High PD-L1 SP142 expression on ICs was significantly associated with favorable clinicopathological parameters and better outcomes in patients with TNBC. Our observations suggest that high IC PD-L1 expression can be used as an independent prognostic marker for predicting better DFS in patients with TNBC.

High TB is associated with adverse features of BC. High TB on pre-NAC biopsy can be used as a predictive biomarker for non-pCR in NAC-treated patients with BC.

Purpose Pancreatic ductal adenocarcinoma (PDAC) is an aggressive tumor with a poor prognosis that poses challenges for diagnosis using traditional tissue-based techniques. DNA methylation alterations have emerged as potential and promising biomarkers for PDAC. In this study, we aimed to assess the diagnostic potential of a novel DNA methylation assay based on epigenetic-specific peptide nucleic acid (Epi-sPNA) in both tissue and plasma samples for detecting PDAC. Materials and methods The study

Using the fifteen cytomorphologic criteria described by this study, pulmonary AdCC could be successfully distinguished from small cell carcinoma. Such a comprehensive approach to an individual case is recommended for the cytologic diagnosis of pulmonary AdCC.

BACKGROUND/AIM: Mohs micrographic surgery (MMS) is a specialized procedure for removing skin tumors. Intraoperative assessment of the resection margin (RM) status using frozen section examination is a crucial component of MMS. This study aimed to identify significant clinicopathological characteristics that could help surgeons determine the optimal surgical extent. PATIENTS AND METHODS: One hundred and fifty-one patients with primary skin tumors were included. The relationship between RM involve

Our observations of the low sensitivity of GE, high discordance rate between gross and microscopic methods, and high sensitivity and specificity of FSA support the necessity of intraoperative FSA for assessing RM status during BCS.

BACKGROUND/AIM: The Oncotype DX Recurrence Score (ORS) predicts the likelihood of recurrence and the benefit of chemotherapy in patients with estrogen receptor (ER)-positive, human epidermal growth factor receptor 2 (HER2)-negative early-stage breast carcinoma (ESBC). Tumor budding (TB) is a poor prognostic factor in breast carcinoma. This study aimed to determine the clinicopathological significance of TB in predicting ORS in patients with ESBC. PATIENTS AND METHODS: We included 359 patients wi
