Abstract
Objectives The aims of this study was to investigate the use of cytologic samples for subclassification of lung adenocarcinoma and the cytologic-histologic correlation in lung adenocarcinoma subtypes using small samples. Methods and Methods Cytological characteristics of lung adenocarcinoma subtypes were summarized by a literature review. Cytology samples from 115 patients with lung adenocarcinoma confirmed by small biopsies were classified by subtype. The diagnostic concordance of subtypes between biopsy and cytology samples was assessed. Results Among the 115 cases, 62 (53.9%) had acinar predominant pattern, 16 (13.9%) were papillary predominant pattern, 29 (25.2%) had solid predominant pattern, 3 (2.6%) had lepidic predominant pattern, and 5 (4.3%) had micropapillary predominant pattern. All corresponding cytologic samples were classified into five subtypes based on cytomorphology features, with concordance rates of 74.2% (46 patients) in c-acinar subtype, 56.3% (nine patients) in c-papillary subtype, 24.1% (seven patients) in c-solid subtype, 66.7% (two patients) in c-lepidic subtype, and 40% (two patients) in c-micropapillary subtype. Collectively, the cytology and small biopsy concordance rate was approximately 57.4%. Conclusion Subtyping of lung adenocarcinoma using cytologic specimens is challenging and the consistency rate varies with the subtype. Acinar predominant tumors have an excellent cytologic-histologic correlation compared to tumors with predominant solid or micropapillary pattern. Evaluating cytomorphologic features of different lung adenocarcinoma subtypes can reduce the false-negative rate of lung adenocarcinoma, particularly for the mild, atypical micropapillary subtype, and improve diagnostic accuracy.

Diagn Cytopathol 2020; 49:18-24. [PMID: 32841545 DOI: 10.1002/dc.24589] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/09/2018] [Revised: 07/03/2020] [Accepted: 08/03/2020] [Indexed: 01/21/2023]
Abstract
BACKGROUND Fine needle aspiration cytology (FNAC) is the first diagnostic step in patient with cervical lymphadenopathy because of its simplicity, safety and early availability of the results. Liquid-based cytology (LBC) is an alternative processing method which is used for both gynecological and nongynecological samples. Literature reviewed show few studies comparing LBC with conventional preparation (CP). AIM The present study was undertaken to evaluate the efficacy of LBC and comparison of LBC and CP in cervical lymphadenopathy. MATERIALS AND METHODS In this prospective study, a total of 75 cases of FNAC with cervical lymphadenopathy were included. The first pass was used for CP followed by LBC with the use of SurePath (SP) technique. Both the smears were compared for cellularity, background containing blood, cell debris, lymphoglandular bodies, stromal fragments, cytoarchitectural pattern, etc., by semiquantitative scoring system. RESULTS There was no statistical difference in the cellularity, cell architecture, and monolayer cells (P > .05). On the basis of background containing blood, cell debris, lympho-glandular bodies, stromal fragments (P < .001), nuclear, and cytoplasmic details (P < .05), LBC was found to be superior to CP. CONCLUSION LBC is a relatively simple technique and superior to CP in respect of better nuclear and cytoplasmic details with loss of background blood and debris. It has a diagnostic accuracy equivalent to that of CP. However, use of both LBC and CP can result in better diagnostic accuracy.

Abstract
Aims and Objectives: The aim of this work was to study the application of Modified Millipore technique (MMT) as a liquid-based tool to have multiple monolayer cellular smears for the routine cytology and Immunocytochemistry. Materials and Methods: In this study, we included 32 effusion fluid samples and 30 fine-needle aspiration cytology (FNAC) samples. From each of the samples, at first routine conventional smear was prepared. The residual samples were processed by MMT to make multiple smear preparation. Both the conventional and MMT of the monolayer cells were evaluated. The various cytomorphological features including the cellularity, background information, nuclear morphology, and cytoplasmic preservation were compared in these two techniques. Result: There were a total of 15 cases of fluid samples and 27 cases of FNAC. Statistical analysis of Mann–Whitney U test showed that the monolayer preparation by MMT and liquid-based cytology of fluid and FNAC smears are of same quality (P > 0.01). Conclusion: Monolayer preparation by MMT is cheap and effective. This technique can be used in routine laboratory for multiple monolayer cell preparations.

Abstract
OBJECTIVES The diagnostic yield of endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) cytology widely varies depending on the treatment method used. Liquid-based cytology (LBC) has gained popularity in the gynecological field because of its efficacy in collection of target cells and simplicity in the manipulation of specimens. Since the introduction of EUS-FNA at our institution, we have used LBC for the diagnosis of pancreatic mass lesions. This study aims to investigate the diagnostic efficacy of EUS-FNA with LBC in patients with pancreatic mass lesions during the learning curve for EUS-FNA. METHODS In this study, we retrospectively enrolled 222 patients with pancreatic mass lesions who were diagnosed using EUS-FNA with LBC between 2011 and 2016. The diagnostic yields for EUS-FNA with LBC for pancreatic mass lesions were evaluated. RESULTS The diagnostic sensitivity, specificity, and accuracy for malignancy were found to be 93.9%, 95.1%, and 94.1%, respectively. CONCLUSIONS This study suggests that EUS-FNA with LBC for specimens provides good diagnostic efficacy in patients with pancreatic mass lesions even during the learning curve for EUS-FNA.

Abstract
Phaeohyphomycosis is a chronic subcutaneous fungal infection caused by dematiaceous fungi, commonly involving the extremities, which present as single or multiple lesions mimicking a benign tumor. Fine-needle aspiration cytology (FNAC) is an easy method for the diagnosis of the lesion. Morphology of the fungus is characteristic with no difficulty for cytopathologist for identification; with a close differential diagnosis of Candida and Aspergillosis. The special stains like periodic acid schiff (PAS) highlights the fungus and the Masson Fontana confirm the melanin pigment and dematiaceous nature of the fungi. Liquid-based cytology (LBC) preparation of the aspirated material was attempted, which is not usually performed on day to day basis. However, in our case the conventional smears were better for appreciating the fungal morphology.

Abstract
Context Liquid-based cytology (LBC) is being extensively used for the evaluation of both gynecological and non-gynecological specimens. Suspension of cells in monolayer makes better morphological assessment possible. Along with this, inherent morphological changes such as altered, reduced, or lost background material, fragmented cell clusters, smaller cell size, nucleolar prominence, etc., need to be considered. Aim Present study was aimed at comparative evaluation of utility of LBC versus conventional smear (CS) in assessing breast lesions and whether it can be used as an alternative to conventional preparation. Settings and Design Present study was a prospective study in which 75 cases of breast fine-needle aspiration cytology from patients with palpable breast lumps constituted the study group. Material and Methods The first pass was used for CS and LBC; a second pass was given. The representative CS and LBC smears were compared using several criteria. Statistics Each feature was scored individually and evaluated statistically using Wilcoxon's signed rank test on the SPSS program. Results A statistically significant difference was found in informative background and background blood-debris, whereas the difference was not statistically significant in other features such as cellularity, cytoarchitectural pattern, presence of monolayer, and nuclear and cytoplasmic details. Conclusion LBC is a promising technique in the field of cytology. It has the potential to decrease the number of slides screened per case and decrease the turn-around-time.

Abstract
Background: Among all diagnostic techniques for breast lesions, fine-needle aspiration (FNA) is the simplest, most reliable and cheapest one. Aim: To compare liquid-based and conventional cytology in diagnosis of breast mass. Materials and Methods: About 101 patients with breast mass were enrolled. The aspirated materials were divided into two parts. One was poured into a liquid medium and the other part was directly spread on clean glass slides. Conventional and liquid-based preparations were compared using several criteria including adequacy (presence of the epithelial cluster or myoepithelial cells), overall cellularity, presence of single epithelial cells, presence of myoepithelial cells, epithelial architecture, nuclear detail, nuclear atypia and inflammatory/proteinaceous background and final diagnosis. Results: Among 101 cases, 85 (84.1%) were malignant and 16 (15.9%) were benign. Conventional and liquid-based cytology were similar according to adequacy (P = 0.65), cellularity (P = 0.13), epithelial architecture (P = 0.15), presence of myoepithelial cells (P = 0.61), nuclear detail (P = 0.57) and nuclear atypia (P = 0.44), while there were a significant difference between the two methods according to the presence of single epithelial cells (P < 0.001) and background (P < 0.001). Conclusion: Liquid-based cytology of breast specimens is an accurate diagnostic tool with high diagnostic yield in benign and malignant lesions.

Diagnostic Utility and Efficacy of Conventional Versus SurePath® Liquid-based Cytology in Head and Neck Pathology: A Study in an Indian Tertiary Care Hospital. IRANIAN JOURNAL OF PATHOLOGY 2018; 13:188-195.

Abstract
BACKGROUND & OBJECTIVE Liquid-based cytology (LBC) is an emerging pathological method for better establishment of the diagnosis in almost all the organs of the body. It is currently used both for the gynecological and non-gynecological (fine-needle aspirates (FNAs)/fluid) specimens in most of the developed and few developing countries. The current study aimed at assessing and illustrating the cytological morphology on SurePath® LBC technique when used on FNAs from head and neck lesions, compared to the conventional smears (CS). METHODS In the current prospective study, a total of 1000 FNAs obtained from swellings of head and neck region were simultaneously processed both by the standard conventional and SurePath® LBC techniques. Both of these preparations were studied, compared with a semi-quantitative scoring system, and statistically analyzed. P-value <0.05 was considered statistically significant. RESULTS LBC smears were better, compared to CS ones, due to the presence of evenly dispersed cells (P≤0.001), clearance of obscuring elements / background debris (P≤0.001), and better cellular details (P≤0.001). However, these abilities of LBC often became its own nemesis and made the interpretation difficult. CONCLUSION LBC, though costly, is an acceptable, simple, and valuable technique. However, CS still cannot be considered inferior to it, and it is recommended that in most of the cases LBC, along with CS, should be reported before reaching a final diagnosis. This is beneficial especially in the developing countries such as India where most of the centers are devoid of LBC technique and hence, are not familiar with many cytomorphological features and potential diagnostic pitfalls unique to it.

Abstract
INTRODUCTION Liquid biopsies, especially the analysis of circulating tumor DNA (ctDNA), as a novel and non-invasive method for the diagnosis and monitoring of non-small cell lung cancer (NSCLC) have already been implemented in clinical settings. The majority of ctDNA is released from apoptotic or necrotic tumor cells, thus reflecting the genetic profile of a tumor. Numerous studies have reported a high concordance in mutation profiles derived from liquid biopsy and tissue biopsy, especially in driver genes. Liquid biopsy could overcome the clonal heterogeneity of tumour biopsy, as it provides a single snapshot of a tumour tissue. Moreover, non-invasiveness is the biggest advantage for liquid biopsy, and the procedure can be repeatedly performed during the treatment for the purpose of monitoring. Therefore, ctDNA could act as a potential complementary method for tissue biopsies in diagnosis, prognostic, treatment response and resistance. Areas covered: This review summarizes the recent advancements in liquid biopsy with a focus on NSCLC, including its applications and technologies associated with assessing ctDNA. The authors conclude the review by discussing the challenges associated with liquid biopsy. Expert commentary: The analysis of ctDNA represents a promising method for liquid biopsy, which will be a novel and potentially complementary method in diagnosis, treatment and prognostic in NSCLC at all stages.
