Correlation of Ultrasound Findings and Fine-Needle Aspiration Cytology for the Diagnosis of Axillary Lymph Node Metastasis in Patients with Breast Carcinoma.

Objective: Ultrasound-guided fine-needle aspiration cytology (USG-FNAC) is used for the detection of axillary lymph node (ALN) metastasis in patients with breast carcinoma (BC). US findings have a good diagnostic accuracy with high sensitivity and specificity. The aim of this study is to correlate the detection of ALN metastases on US with FNAC in BC patients.

Metastatic breast carcinoma in pleural fluid: Correlation of receptor and HER2 status with the primary carcinoma-a pilot study.

Background: Documenting the four molecular subtypes of breast carcinoma is significant as they determine response to therapy, disease free interval and survival. Our aim was to document the subtypes defined by immunohistochemistry (IHC) expression of estrogen receptor (ER), progesterone receptor (PR) and human epidermal growth factor receptor 2 (HER2): namely ER + PR+ HER2+; ER + PR + HER2-; ER-PR-HER2+; and ER-PR-HER2- in metastatic breast carcinoma in pleural fluid and compare them with their expression in the primary breast tumor.

Methods: Over a period of 18 months, 13 cases of invasive breast carcinoma with metastases to the pleural cavity were studied for subtypes.

Subclassification of pulmonary non-small cell lung carcinoma in fine needle aspirates using a limited immunohistochemistry panel.

Background: Newer treatment modalities require subtyping of non-small cell lung carcinomas (NSCLC). Morphological differentiation is often difficult and various immunohistochemical (IHC) panels have been used to maximize the proportion of accurately subtyped NSCLC.

Aim: The aim of this study was to subtype NSCLC on fine needle aspirates (FNA) using a minimal antibody panel.
