ultrasonography and fine needle Aspiration Cytology can spare breast cancer patients unnecessary sentinel lymph node biopsy
Annals of Surgical Oncology, 2006Co-Authors: Maartje C Van Rijk, Eline E Deurloo, Omgo E Nieweg, Kenneth G A Gilhuijs, J L Peterse, Emiel Th J Rutgers, R Kroger, Bin B R KroonAbstract:Some 30% to 40% of the breast cancer patients scheduled for sentinel node biopsy have axillary metastasis. Pilot studies suggest that ultrasonography is useful in the preoperative detection of such nodes. The aims of this study were to evaluate the sensitivity of preoperative ultrasonography and fine-needle Aspiration Cytology for detecting axillary metastases and to assess how often sentinel node biopsy could be avoided. Between October 1999 and December 2003, 726 patients with clinically negative lymph nodes were eligible for sentinel node biopsy. A total of 732 axillae were examined. Preoperative ultrasonography with subsequent fine-needle Aspiration Cytology in case of suspicious lymph nodes was performed in all patients. The sentinel node procedure was omitted in patients with tumor-positive axillary lymph nodes in lieu of axillary lymph node dissection. Ultrasound and fine-needle Aspiration Cytology established axillary metastases in 58 (8%) of the 726 patients. These 58 were 21% of the total of 271 patients who were proven to have axillary metastasis in the end. Of the patients with ultrasonographically suspicious lymph nodes and negative Cytology, 31% had tumor-positive sentinel nodes. Patients with preoperatively established metastases by ultrasonography and fine-needle Aspiration Cytology had more tumor-positive lymph nodes (P < .001) than patients with metastases established later on. The sensitivity of ultrasonography and fine-needle Aspiration Cytology is 21%, and unnecessary sentinel node biopsy is avoided in 8% of the patients. This approach improves the selection of patients eligible for sentinel node biopsy.

adequacy of cytologic samples by ultrasound guided percutaneous transthoracic fine needle Aspiration Cytology of peripheral pulmonary nodules for morphologic diagnosis and molecular evaluations comparison with computed tomography guided percutaneous transthoracic fine needle Aspiration Cytology
Archives of Pathology & Laboratory Medicine, 2020Co-Authors: Immacolata Cozzolino, Andrea Ronchi, Gaetana Messina, Marco Montella, Floriana Morgillo, Giovanni Vicidomini, Virginia Tirino, Anna Grimaldi, Federica Zito Marino, Mario SantiniAbstract:Context.— Fine-needle Aspiration Cytology (FNAC) of pulmonary nodules is usually guided by computed tomography (CT), whereas ultrasonography (US) is generally considered not applicable for such pur...

ultrasound guided fine needle Aspiration Cytology prior to sentinel lymph node biopsy in melanoma patients
Annals of Surgical Oncology, 2006Co-Authors: Christiane Voit, Martina Kron, Gregor Schafer, Alfred Schoengen, H Audring, Ansgar Lukowsky, Markus Schwurzervoit, Wolfram Sterry, Helmut Winter, Jurgen RademakerAbstract:Background Sentinel lymph node biopsy (SLNB) allows early detection of metastases, thereby enabling early treatment in melanoma patients likely to benefit from adjuvant therapies. This prospective study analyzes the possible benefits of additional ultrasound (US) and fine needle Aspiration Cytology (FNAC) of sentinel nodes (SN) prior to SLNB.

primary pulmonary botryomycosis diagnosed by fine needle Aspiration Cytology a case report
Acta Cytologica, 2006Co-Authors: Jesus Veraalvarez, Miguel Marigilgomez, Maria Dolores Garciaprats, Manuel Abascalagorreta, Pascual ValadanAbstract:BACKGROUND: Primary pulmonary botryomycosis is an uncommon suppurative bacterial infection of the lung. Cytologic findings by conventional methods and thin-layer preparations in1 case are presented. CASE: A 45-year-old man had primary pulmonary botryomycosis diagnosed by fine needle Aspiration Cytology (FNAC). Aspiration smears were characterized by densely packed microorganisms surrounded by polymorphonuclear leukocytes. Microbiologic analysis of cytologic material revealed colonies of Streptococcus constellatus. CONCLUSION: FNAC diagnosis of pulmonary botryomycosis offers the opportunity to distinguish this bacterial infection from lung cancer and avoid unnecessary surgery.

diagnostic value of fine needle Aspiration Cytology in lymph node metastasis of nasopharyngeal carcinoma
Hainan Medical Journal, 2007Co-Authors: Yang HuaAbstract:Objective To investigate the diagnostic value of fine needle Aspiration Cytology(FNAC) in lymph node metastasis of nasopharyngeal carcinoma. Methods FNAC was performed in fleet-lymph nodes, then we contradistinguished the Cytology diagnosis and histological diagnosis. Results 101 cases were diagnosed as lymph node metastasis of nasopharyngeal carcinoma by Cytology, comparied with histologic diagnosis, the diagnostic accuray of Cytology was 98%(99/101), 3 cases were false negative, 2 cases were falsepositive. Conclusions FNAC is of great value to confirm the diagnosis of lymph nodes metastasis of nasopharyngeal carcinoma, especially, for the patients with lymph nodes metastasis without nasopharyngeal symptom.
