Objective: To evaluate the role of Fine Needle Aspiration Cytology in the preoperative diagnosis of malignancy in parotid and submandibular gland neoplasm. Methods: This cross sectional study on 50 cases was conducted in the Department of Otolaryngology and Head-Neck Surgery of Sir Salimullah Medical College Mitford Hospital and Dhaka Medical College Hospital from January’2009 to June 2010. Results: Fine needle aspiration cytology findings of our all 50 cases were compared with postoperative histopathological reports. Out of the 50 cases, in 36(72%) cases of benign neoplasm and 7(14%) cases of malignant neoplasm, pre-operative FNAC findings and post operative histopathological findings were same. In 7 cases, FNAC and post operative histopathological findings did not matched. These were 2 (4%) false positive and 5 (10%) false negative result.In our study sensitivity of FNAC for reporting malignancy was 58.33%, specificity to rule out malignancy was 94.73% and overall accuracy in detecting malignant tumour was 86%. Positive predictive value and negative value were 77.77% and 87.80% respectively. It can be concluded that fine needle aspiration cytology is a safe, cheap and useful preoperative diagnostic tool in the diagnosis of malignancy in parotid and submandibular gland, but as fine needle aspiration cytology partly depends on operator skill, it may give false negative and false positive result. Conclusion: FNAC is a useful preoperative diagnostic tool for malignant parotid and submandibular glands with high specificity and sensitivity.

The National Public Health Program has established the organized mammography screening in Hungary. The aim of this study was to conduct an audit of “gray zone” smears of the organized mammography screening in comparison with histopathological diagnoses. Methods: Cytology results were rated to C3 atypia probably benign and C4 suspicious of malignancy. Results: 1361 women had aspiration cytology performed from a total of 47,718 mammography non-negative lesions. 105 (7.8%) were diagnosed as C3, whereas 78 (5.7) as C4. Of the 105 patients with C3 diagnosis 61 (58%) patients underwent surgical biopsy. Histology proved malignancy in 20 (32.8%) cases, and benign lesion in 41 (67.2%) cases. All (100%) of the 78 patients with C4 diagnosis had open biopsies; 69 (88.4%) cases were histologically malignant and 9 (11.6%) cases were benign lesions. Conclusion: The auditing results of fine needle aspiration cytology of “gray zone” in organized mammography screening meet the proposed threshold values. Authors conclude that the “gray zone” category in breast cytology is useful and of value if used judiciously. Orv. Hetil., 2011, 152, 292–295.

A Nemzeti Népegészségügyi Program az emlőrák szervezett szűrését biztosítja. Célkitűzés: Dolgozatunk célja a szervezett emlőrákszűrés során a mammográfia, illetve ultrahangvizsgálatokkal nem negatív elváltozások aspirációs citológiai diagnózisainak minőségbiztosítása. Módszer: A citológiai diagnózisokat 5 kategóriába (C1, C2, C3, C4, C5) soroltuk. A citológiai módszer diagnosztikus érzékenységét a szövettani eredményekhez viszonyítva elemeztük. Eredmények: Összesen 47718 mammográfiás és ultrahangvizsgálattal a kóros emlőelváltozásokból 1361 citológiai vizsgálatot végeztünk. A leggyakoribb diagnózis benignus (805 eset, 59, 1%), illetve carcinoma (187 eset, 13,7%) volt. Az összesített pozitív, negatív esetek számításánál a szenzitivitás 91%, a specificitás 88%, a pozitív prediktív érték 96,6%, a negatív prediktív érték 71%-nak (p<0,001) bizonyult. Megbeszélés: Megállapítottuk, hogy tanulmányunkban az emlőelváltozások vékonytű-aspirációs citológiai vizsgálatainak minőségbiztosítási eredményei megfelelnek, és több tekintetben jobbak a nemzetközileg elvárt követelményeknél.
