OBJECTIVE To determine the diagnostic accuracy of ultrasound guided fine needle aspiration (FNA) cytology and core needle biopsy (CNB) of axillary lymph nodes pre-operatively in newly diagnosed operable primary breast cancer. METHODS An observational study for all patients who underwent pre-operative FNA cytology or CNB during September 2013-August 2014 was conducted at our institution (Count...

BACKGROUND Endoscopic ultrasound guided fine needle aspiration biopsy (EUS-FNA) is a recent innovation in the evaluation of gastrointestinal and pulmonary malignancies. AIMS To review the experience with EUS-FNA of a large single centre. METHODS 333 consecutive patients underwent EUS-FNA. Follow up data were available on 327 lesions in 317 patients, including 160 lymph nodes, 144 pancreatic...

BACKGROUND/AIMS Endoscopic ultrasound-guided fine needle aspiration and/or biopsy (EUS-FNA/B) have been used to diagnose subepithelial tumors (SETs) and extraluminal lesions in the gastrointestinal tract. Our group previously reported the usefulness of EUS-FNA/B for rectal and perirectal lesions. This study reports our expanded experience with EUS-FNA/B for rectal and perirectal lesions in term...

RATIONALE Assessment of mediastinal lymph nodes is recommended in patients with non-small cell lung cancer without distant metastases. Linear transesophageal endoscopic ultrasound with real-time guided fine-needle aspiration (EUS-FNA) is a promising, nonsurgical tool for mediastinal staging. OBJECTIVES We conducted a randomized controlled trial comparing surgical staging with EUS-FNA. METHO...

The aim of this retrospective study is to evaluate the diagnostic yields of combining fine needle aspiration (FNA) with brushing cytology (BC) in clinical work-up of pancreatic ductal adenocarcinoma. The study included a total of 97 patients who underwent both FNA and BC along with histologic/clinical follow-up (F/U). Cytologic diagnoses were categorized as negative for neoplasm (NEG), atypical...

background: to reduce uncertainties of patient positioning, the computerized tomography (ct) images acquired at the treatment planning time can be compared with those images obtained during radiation dose delivery. this can be followed during dose delivery procedure as image guided radiotherapy (igrt) to verify the prescribed radiation dose delivery to the target as well as to monitor radiation...

To compare the value of cytokeratin fragment 21-1 (CYFRA 21-1) concentration in the fine-needle biopsy aspirates (fine needle aspirate [FNA] CYFRA 21-1) with cytopathology of fine-needle aspiration biopsy (FNA cytology) and to assess whether CYFRA 21-1 concentrations from ultrasound-guided fine-needle aspiration biopsy (US-FNAB) specimens (FNA CYFRA 21-1) is not inferior to FNA cytology in the ...

OBJECTIVE We aimed to assess the adequacy and efficacy of ultrasound (US)-guided fine-needle aspiration (US-FNA) for small solid thyroid nodules (SSTNs) with the largest diameter <5 mm and compared these according to nodule size. STUDY DESIGN Among 656 SSTNs in 569 patients, each SSTN was classified into 1 of 4 groups according to the largest diameter: 1 mm ≤ group A < 2 mm; 2 mm ≤ group B < ...

background: breast conservation therapy (bct) is the standard of care for early stage breast cancer. the procedure can be a challenge for the surgeon if the lesion is non-palpable. for excision of non-palpable breast lesions, they should be localized precisely before surgery. there are different techniques such as the wgl (wire guided localization), roll (radio-guided occult lesion localization...
