CD301 and LSECtin glycan-binding receptors of innate immune cells serve as prognostic markers and potential predictors of immune response in breast cancer subtypes. Glycobiology 2024; 34:cwae003. [PMID: 38206856 PMCID: PMC10987291 DOI: 10.1093/glycob/cwae003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/25/2023] [Revised: 12/18/2023] [Accepted: 12/18/2023] [Indexed: 01/13/2024] Open
Abstract
Glycosylation is a prominent posttranslational modification, and alterations in glycosylation are a hallmark of cancer. Glycan-binding receptors, primarily expressed on immune cells, play a central role in glycan recognition and immune response. Here, we used the recombinant C-type glycan-binding receptors CD301, Langerin, SRCL, LSECtin, and DC-SIGNR to recognize their ligands on tissue microarrays (TMA) of a large cohort (n = 1859) of invasive breast cancer of different histopathological types to systematically determine the relevance of altered glycosylation in breast cancer. Staining frequencies of cancer cells were quantified in an unbiased manner by a computer-based algorithm. CD301 showed the highest overall staining frequency (40%), followed by LSECtin (16%), Langerin (4%) and DC-SIGNR (0.5%). By Kaplan-Meier analyses, we identified LSECtin and CD301 as prognostic markers in different breast cancer subtypes. Positivity for LSECtin was associated with inferior disease-free survival in all cases, particularly in estrogen receptor positive (ER+) breast cancer of higher histological grade. In triple negative breast cancer, positivity for CD301 correlated with a worse prognosis. Based on public RNA single-cell sequencing data of human breast cancer infiltrating immune cells, we found CLEC10A (CD301) and CLEC4G (LSECtin) exclusively expressed in distinct subpopulations, particularly in dendritic cells and macrophages, indicating that specific changes in glycosylation may play a significant role in breast cancer immune response and progression.

Abstract
In contrast with the other organs such as the lung, small cell tumors have been less studied in the breast due to their relatively less frequency. Although rare, neuroendocrine neoplasms, some lymphomas, and some small cell sarcomas such as undifferentiated small round cell sarcoma and rhabdomyosarcoma can be seen in small cell morphology in the breast. Many cytological specimens such as fine-needle aspiration biopsies and touch imprint cytology are used for diagnosis and further prognostic/predictive marker determination in primary breast masses, sentinel and axillary lymph nodes, and metastatic masses. Lobular carcinoma deserves to be considered in the small cell tumor group because of its small, monomorphic, discohesive, scant cytoplasmic cytological features. Since so many different types of tumors in the breast can have small cell characteristics, they should be divided into small cell neuroendocrine tumors and small cell nonneuroendocrine tumors. When evaluating small cell breast tumors cytologically, wide tumor diversity should be kept in mind, and clinical, hematological, and radiological features should be taken into consideration.

Abstract
Background: Breast lesions extend from benign to malignant ones. The National Cancer Institute recommended categories for the diagnosis of breast cytology. There are some lesions in the breast which are called intermediate or gray lesions. It includes C3 (atypical, probably benign) and C4 (suspicious, favor malignant) which needs to be evaluated. Materials and Methods: This study was conducted in the Department of Pathology, Uttar Pradesh University of Medical Sciences, Saifai, Etawah (Uttar Pradesh). Fine-needle aspiration cytopathology (FNAC) was the diagnostic tool. The present study was undertaken to determine the gray lesions of the breast and its correlation with histopathology and other associated parameters. Immunohistochemistry was applied where ever necessary. One hundred and fifty one cases of gray lesions of the breast were included. Results: C3 was seen in 85 (56.29%) and C4 in 66 (43.70%) patients. The maximum number of patients was of 31–40, (33.77%) years age group, the youngest patient was 12-year-old female, whereas the oldest was 86 years male. Histopathology evaluation confirmed malignancy in 35 (23.17%) cases, and infiltrating ductal carcinoma was the frequent malignancy (24 [68.5%]). Sensitivity, specificity, positive predictive value, and negative predictive value of C4 category for the diagnosis of malignancy were, respectively, 81.48%, 50%, 68.7%, and 64.2%. Conclusion: FNAC is an excellent diagnostic tool. It has some limitations, especially with the gray lesions, which may lead to miss interpretation in diagnosis, so a scope of mistake to the cytopathologist is always there. These lesions need to be evaluated because of the risk of malignancy. However, gray lesions can be reduced by cytology followed by histopathology examination along with ancillary radiological investigations such as mammography and ultrasonography.

Diagn Cytopathol 2021; 49:1022-1031. [PMID: 34133084 DOI: 10.1002/dc.24808] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/22/2020] [Revised: 04/14/2021] [Accepted: 05/19/2021] [Indexed: 11/11/2022]
Abstract
BACKGROUND Recently the International Academy of Cytology (IAC) introduced a new reporting system for breast fine-needle aspiration cytology that classifies cytologic diagnoses into five-categories: (I) insufficient material, (II) benign, (III) atypical, (IV) suspicious of malignancy, and (V) malignant. The current study was undertaken to categorize the breast lesions utilizing the newly proposed IAC Yokohama classification system and evaluate the risk of malignancy (ROM) for respective categories and the diagnostic yield of this technique. METHODS All FNAs of breast lesions over 2.5 years were categorized retrospectively using the newly proposed IAC Yokohama reporting system. The ROM was calculated along with sensitivity, specificity, positive and negative predictive value, diagnostic accuracy, false positive, and false-negative rate using the histological diagnosis as the gold standard. RESULTS The 512 cases were distributed as follows: Category I (insufficient material) 7.4%, Category II (benign) 74%, Category III (atypical) 5.7%, Category IV(suspicious) 1.4%, and Category V (malignant) 11.5%. Histopathological correlation was available in 285 (55.7%) cases. The respective ROM calculated was 33.3%, 0.5%, 13.3%, 83.3%, and 100% for Category I-V. The Sensitivity, Specificity, Positive and Negative Predictive Value, and Diagnostic accuracy were 95%, 99.5%, 98.27%, 98.6, and 98.5% respectively. CONCLUSIONS Despite previous attempts to establish a standardized diagnostic terminology, there has been a lack of a single internationally approved standardized reporting system allowing substantial diagnostic clarity and incorporating distinct diagnostic categories, each linked with a specific ROM and recommended management. This System also provides enhanced communication between pathologists and attending clinicians for the benefit of the patient.

Abstract
BACKGROUND The International Academy of Cytology (IAC) Yokohama reporting system was recently proposed to serve as a standardized diagnostic platform for the cytological interpretation of breast fine needle aspiration biopsy (FNAB). Five cytological categories were suggested, linked to a certain risk of malignancy (ROM). The aim of this study was to assess the potency of this newly proposed reporting guideline, with a review of literatures. METHODS This is a retrospective study over 8-year duration in which all the breast FNABs performed in our institution were recategorized in accordance to the IAC Yokohama reporting system. Kappa coefficient was used to evaluate the agreement between the proposed cytological category and corresponding histological diagnosis, with the level of significance set at 5%. Cyto-histopathological correlation and its diagnostic performance were also assessed. RESULTS A total of 1136 breast FNABs were analyzed, including 31 repeat FNABs. Of these, 521 (47.1%) cases had matched histopathological results. Respective ROM for each category was: "insufficient" 13.6%, "benign" 0.4%, "atypical" 25.0%, "suspicious" 85.7%, and "malignant" 100%. There was substantial agreement (κ=0.757) between cytology and histopathological results. Our data revealed a high-diagnostic specificity, sensitivity, positive and negative predictive value of 99.3% (95% CI: 97.6%-99.9%), 94.2% (95% CI: 87.9%-97.9%), 98.0% (95% CI: 92.5%-99.5%), 98.0% (95% CI: 96.1%-99.1%) respectively when both the "suspicious" and "malignant" cases were considered as positive tests, with area under the curve of 0.993. CONCLUSIONS The IAC Yokohama system is a reliable, evidence-based, and standardized reporting system that helps to facilitate communication among cytopathologists, radiologists, and surgeons toward individualized patient management.

Abstract
Abstract
Background
Breast cancer is a major public health problem worldwide. It is recommended that small breast lesions or those suspicious for malignancy be evaluated via histopathological examination (“core biopsy” or surgical specimens), and lesions that are probably benign and palpable should be examined via fine-needle aspiration cytology (FNAC). This study aimed to assess the accuracy of FNAC for the diagnosis of small breast lesions.
Methods
We reviewed all anatomopathological reports of FNACs collected between January 1, 2000 and December 31, 2019 (n = 24,721) in a private community pathology service. Lesions up to 1.0 cm (≤1.0 cm) (n = 8334) were included for evaluation and classified according to the recommendation of the International Academy of Cytology Yokohama System for Reporting Breast Fine Needle Aspiration Biopsy Cytopathology in the following categories: (1) insufficient/inadequate; (2) benign; (3) atypical, probably benign; (4) suspicious of malignancy; and (5) malignant. Subsequently, the results of the FNACs were compared to those of the respective histopathological examinations (n = 785).
Results
FNAC had a specificity of 99.6%; sensitivity, 97.4%; positive predictive value, 99.6%; negative predictive value, 97.6%; and accuracy, 98.5%.
Conclusions
FNAC is a reliable method for diagnosing small breast lesions (≤1.0 cm).

Abstract
BACKGROUND The International Academy of Cytology (IAC) Yokohama system is a recently proposed system for reporting breast cytology by fine needle aspiration biopsies (FNAB). Multiple studies are needed to confirm the risk of malignancy (ROM) of the various reporting categories of this system. The present article studies the accuracy of the IAC Yokohama system in our center. METHODS Over a period of 1 year (September 2018-August 2019), all cases of breast masses assessed by FNAB and histological correlation were studied retrospectively. Sensitivity, specificity, negative predictive value (NPV) and positive predictive value (PPV) and overall accuracy of the IAC Yokohama system for diagnosing malignancy were assessed. The rates of malignancy (ROM) of each diagnostic category were also estimated. RESULTS Three hundred and twenty-one FNABs had cyto-histological correlation. The percent sensitivity (with 95% Confidence Intervals) when the atypical, suspicious of malignancy and the malignant categories were regarded as positive for malignancy were 98.2% [95.5%, 99.5%], 96.0% [92.5%, 98.2%], and 86.7% [81.5%, 90.8%] respectively. The percent specificity (with 95% Confidence intervals) for the same categories in the same order were 59.5% [47.4%, 70.7%], 91.9% [83.2%, 97.0%], and 100% [95.1%, 100%] respectively. The area under curve (AUC) for diagnosing malignancy was 0.981[0.963, 0.993]. The ROM for the benign, atypical, suspicious of malignancy and malignant category were 8.3% [2.3%, 20.0%], 17.2% [5.8%, 35.8%], 77.8% [57.7%, 91.4%], and 100% [98.1%, 100%] respectively. CONCLUSION The IAC Yokohama system is suitable for accurately reporting breast lesions on FNAB.

Abstract
OBJECTIVE Phyllodes tumors are fibroepithelial breast lesions with many cytological and histopathological similarities to fibroadenomas. The aim of this study was to investigate cytological findings in benign phyllodes tumors. STUDY DESIGN Seventy-six histologically proven cases of benign phyllodes tumors were selected from 1982 to 2017. Cytological criteria, including cellularity, the number and shape of epithelial clusters, the shape and number of stromal fragments, and the presence of atypia, were evaluated. RESULTS Cytological slides were hypercellular and showed dimorphic populations of cells. The epithelial clusters were moderate in amount and had a bonsai-like configuration. The stromal fragments consisted of oval-to-spindle shaped cells with preservation of the cytoplasm. Some popcorn-like cells and intranuclear inclusions in stromal cells and deposition of pinkish and amorphous material at the border of the stromal fragments were also noted in the stromal cells. CONCLUSION Stromal hypercellularity and large amounts of stromal fragments, the presence of bonsai-like epithelial clusters, and deposition of amorphous pinkish material at the border of the stromal fragments, as well as newly observed findings including the presence of intranuclear inclusions and popcorn-like nuclei in the stromal cells, can aid in the diagnosis of phyllodes tumors.

Abstract
INTRODUCTION Granulomatous Mastitis (GM) is a rare, benign, inflammatory disease of the breast. It is a well known mimicker of malignancy, clinically and radiologically. Patients are often subjected to number of tests for the right diagnosis. Non-specific Granulomatous Mastitis (NGM) and Tubercular Mastitis (TBM) are chief among the various causes of GM. They are important to be diagnosed early as their treatment varies significantly. Fine Needle Aspiration Cytology (FNAC) is simple, patient friendly and primary investigation modality in cases of lump in breast. AIM To find out the utility of FNAC in differentiating NGM and TBM. MATERIALS AND METHODS All cases of granulomatous mastitis diagnosed on cytology over eight years were retrospectively retrieved. The clinical and radiological history was obtained from the patient file. The slides were stained with haematoxylin and eosin stain as well as Leishman stains. Special stains like Periodic Acid Schiff (PAS) and Ziehl Neelsen (ZN) stain were used for fungus and Mycobacteriumtuberculosis respectively. Histopathological correlation of the available cases was done. Clinical presentation and cytological morphology of individual cases was studied in detail. RESULTS Twenty one cases of GM obtained, of which 16 were NGM and five were TBM. Both diseases were common among young reproductive women who presented with unilateral breast lump of varying duration. Almost 25% of NGM and 60% of TBM has clinical suspicion of malignancy. About 30% had radiological suspicion of malignancy. Nearly 62.5% of NGM patients had painful swelling and none of tubercular mastitis patients had pain. About 31% of NGM patients underwent prior abscess drainage and 40% of TBM patients gave history of tuberculosis. Almost 6.25% of NGM and 60% of TBM had axillary lymphadenopathy. Cytologically epithelioid cells were identified in 100% of patients whereas, granulomas were seen in 62.5% and 80% of NGM and TBM smears respectively. Langhans giant cells were frequent among TBM and foreign body giant cell among NGM. Caseous necrosis was seen in 60% of TBM and absent in NGM smears. CONCLUSION Though, NGM and TBM is said to have overlapping features, our study highlights few clinical and cytological differences which aid in differentiating the two entities at primary level. FNAC along with special stain must be advocated as the primary tool of diagnosis in cases of GM.
