Title

Publisher : Faculty of Medicine Universitas Indonesia

Background: Fine-needle aspiration (FNA) is an effective and safe procedure for analyzing salivary gland lesions. Various morphological and overlapping cytomorphology features can bring difficulty in diagnosis of the salivary gland lesions. This study aimed to evaluate the diagnostic accuracy of fine needle aspiration cytology of salivary glands lesions.Methods: There were 107 cases of cytology and 39 cases of histopathology of salivary gland lesions collected and reviewed from the archives of Anatomical Pathology Department, Faculty of Medicine, Universitas Indonesia / Cipto Mangunkusumo Hospital from 2005-2009. Seven cases of cytology were excluded, due to unsatisfactory specimens. Diagnostic test was applied to analyze the 39 pairs of cytology-histopathology cases.Results: There were 100 cases of salivary gland lesions cytology obtained, consisted of 27 negatives, eight cases inconclusive and 65 cases of neoplastic lesions. Of the 39 pair cases, fourteen cases showed result discrepancies between cytology and histopathology, with 3 false-negative cases and 1 false-positive case. The sensitivity and specificity of cytology analysis in differentiating malignant from non-malignant lesions were 82.35%, and 95.45% respectively, NPV 87.5% and PPV 93.34%.Conclusion: This study showed diagnostic accuracy of FNA cytology salivary gland lesions was varied, with 82.35% sensitivity and 95.45% specificity in differentiating malignant from non-malignant hence this information can still be used for case management.

Overexpression of p53 in extra large (more than 10 cm) hepatocellular carcinoma Lalisang, Toar J.M.; Moenadjat, Yefta; Siregar, Nurjati C.; Stephanie, Marini

Background: Extra large hepatocellular carcinoma (HCC) of >10 cm managed in our center shows a specific characteristic in tropical regions. This type of HCC exhibits distinct p53 expression. This study aimed to determine the association between p53 expression and tumor size and behavior. Method: Subjects with HCC who underwent surgical resection in our hospital during 2012–2015 were enrolled in thisstudy. Subject’s characteristics, tumor size, histopathology findings, and tumor behavior were variables observed. Animmunohistochemical study on p53 expression was conducted to determine its association with those variables.Results: This study involved 38 subjects with tumor size ranging from 3 cm to 25 cm in diameter and 20 subjects (52.8%) with tumor size ranging from 10 cm to 25 cm in diameter. Only 13 samples were evaluated for p53 expression. Five subjects with >10 cm (extra large) tumor showed highly/overexpressed p53 (intensity>50%), two subjects with strong p53 expression (intensity>5%–50%), and two subjects with weak expression. Three subjects with <10 cm (large) tumor showed strong expression of p53 (5%–9%) and a subject with 3 cm tumor showed weak p53 expression (<5%). Highly expressed p53 was found in patients with microvascular invasion, inflammatory response, mitosis, and necrosis.Conclusion: Overexpression of p53 was associated with extra large and poorly differentiated HCC.

The low prevalence of colonic serrated adenocarcinoma with high KRAS mutational status at Cipto Mangunkusumo Hospital, Indonesia Rahadiani, Nur; Handjari, Diah R.; Stephanie, Marini; Krisnuhoni, Ening

Background: Serrated adenocarcinoma (SA), a subtype of colorectal carcinoma, and the KRAS mutation, a strong marker for the patient’s response to anti-epidermal growth factor receptor therapy, have a clinical importance because of its progressive nature and tendency for chemoresistance. The purposes of this study were to (1) determine the prevalence of SA, (2) evaluate the histomorphological characteristics of SA and classical adenocarcinoma based on its prognostic factors, (3) determine the prevalence of the KRAS mutation in SA cases, and (4) identify the main characteristics of SA cases and classical adenocarcinoma with a KRAS mutation.Methods: This study was conducted by reviewing hematoxylin-eosin-stained slides of colorectal carcinoma (CRC) cases from January 2013 to July 2015 at the Department of Anatomical Pathology Cipto Mangunkusumo General Hospital. The final diagnosis of SA was based on the Tuppurainen et al criteria and the KRAS mutation was evaluated using real-time polymerase chain reaction.Results: Among the 117 adenocarcinoma cases, there were 41 unequivocal SA, 11 equivocal SA, and 65 classical adenocarcinoma. The prevalence rates of unequivocal and equivocal SA among all CRC cases were 7.7% and 2.1%, respectively. There were 11 (28.2%) cases of wild-type KRAS and 28 (71.7%) cases of mutated KRAS among all unequivocal SA cases. Tumor budding (TB) was the predominant prognostic factor.Conclusion: The prevalence of SA among all CRC cases was 7.7%. The KRAS mutation was found in almost three-quarters of all SA cases.
