Cellphone enabled point-of-care assessment of breast tumor cytology and molecular HER2 expression from fine-needle aspirates. NPJ Breast Cancer 2021; 7:85. [PMID: 34215753 PMCID: PMC8253731 DOI: 10.1038/s41523-021-00290-0] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/11/2020] [Accepted: 06/03/2021] [Indexed: 12/13/2022] Open
Abstract
Management of breast cancer in limited-resource settings is hindered by a lack of low-cost, logistically sustainable approaches toward molecular and cellular diagnostic pathology services that are needed to guide therapy. To address these limitations, we have developed a multimodal cellphone-based platform—the EpiView-D4—that can evaluate both cellular morphology and molecular expression of clinically relevant biomarkers directly from fine-needle aspiration (FNA) of breast tissue specimens within 1 h. The EpiView-D4 is comprised of two components: (1) an immunodiagnostic chip built upon a “non-fouling” polymer brush-coating (the “D4”) which quantifies expression of protein biomarkers directly from crude cell lysates, and (2) a custom cellphone-based optical microscope (“EpiView”) designed for imaging cytology preparations and D4 assay readout. As a proof-of-concept, we used the EpiView-D4 for assessment of human epidermal growth factor receptor-2 (HER2) expression and validated the performance using cancer cell lines, animal models, and human tissue specimens. We found that FNA cytology specimens (prepared in less than 5 min with rapid staining kits) imaged by the EpiView-D4 were adequate for assessment of lesional cellularity and tumor content. We also found our device could reliably distinguish between HER2 expression levels across multiple different cell lines and animal xenografts. In a pilot study with human tissue (n = 19), we were able to accurately categorize HER2-negative and HER2-positve tumors from FNA specimens. Taken together, the EpiView-D4 offers a promising alternative to invasive—and often unavailable—pathology services and may enable the democratization of effective breast cancer management in limited-resource settings.

Abstract
CONTEXT.— The College of American Pathologists surveys provide national benchmarks of pathology practice for laboratories. OBJECTIVE.— To investigate breast fine-needle aspiration (FNA) biopsy practice in domestic and international laboratories in 2019. DESIGN.— We analyzed data from the College of American Pathologists Breast FNA Practice Supplemental Questionnaire that was distributed to laboratories participating in the 2019 College of American Pathologists Non-Gynecologic Cytopathology Education Program. RESULTS.— Sixty-one percent (499 of 816) of respondent laboratories routinely evaluated breast FNAs. Cystic lesions were the most common indication, and radiologists primarily performed FNAs in most settings. Forty-five percent (220 of 491) of laboratories performed ancillary studies on breast FNA samples, but 33.8% (70 of 207) did not report fixation time for breast biomarker studies. Only 54.5% (271 of 497) of laboratories had a standardized reporting system and only 16.8% (82 of 488) were aware of the International Academy of Cytology Yokohama Breast FNA Biopsy Cytology Reporting System. There were significant differences among different types of institutions in several aspects of breast FNA practice, including frequency of concurrent FNA and core needle biopsy for the same lesion, primary personnel who performed the FNA, etc. Significant differences existed between domestic and international laboratories in slide preparation, ancillary studies, fixation time reporting, standardized/descriptive diagnosis, and International Academy of Cytology Yokohama Reporting System awareness. CONCLUSIONS.— This is the first survey from the College of American Pathologists Cytopathology Committee to investigate breast FNA practices. The data reveal significant differences in breast FNA practice among different types of institutions and between domestic and international laboratories, and provide a baseline for future breast FNA studies in a variety of practice settings.

Abstract
OBJECTIVE The aim of this study is to evaluate the accuracy of sub-classification of breast diseases using Fine Needle Aspiration cytology (FNAC). MATERIALS AND METHODS A one-year prospective study of 180 consecutive patients with palpable breast lesions who underwent FNAC and subsequently open surgical biopsy for histological confirmation. FNAC was used to sub-classify breast lesions and then correlated with histological diagnosis. RESULTS A total of 180 patients were enrolled into the study but only 110 patients with histology report were used for test validity. Seventeen (15.5%) smears were C1; while 46 (41.8%), 5 (4.5%), 4 (3.6%) and 38 (34.6%) were C2, C3, C4 and C5, respectively. FNAC achieved sensitivity of 90.0%, specificity of 95.5%, false positive rate of 5.3%, false negative rate of 8.7%, positive predictive value of 94.7%, negative predictive value of 91.3% and overall diagnostic accuracy of 92.9%. Only 86 (78.2%) of the 110 smears could be sub-classified into different disease conditions of the breast on cytology. FNAC accurately sub-classified 25(78.1%) of fibroadenoma and 28(87.5%) of invasive ductal carcinoma. CONCLUSION FNAC can reasonably sub-classify fibroadenoma, invasive ductal carcinoma and mastitis but there is still a challenge with lobular carcinomas, metaplastic carcinomas, papillary carcinomas and fibrocystic changes.

Abstract
In recent times, the diagnosis of breast lesions has mostly become dependent on core needle biopsies (CNBs) with a gradual reduction in the rate of performing fine-needle aspiration cytology (FNAC). Both the procedures have their pros and cons and outsmart each other taking into account different parameters. Both the methods are found to be fraught with loopholes, taking into account different performance indices, diagnostic accuracy and concordance, patient benefit, and cost-effectiveness. Unlike the popular belief of an absolute superiority of CNB over FNAC, the literature review does not reveal a very distinct demarcation in many aspects. We recommend judicious use of these diagnostic modalities in resource-limited settings and screening programs taking into account parameters such as palpability and availability of an experienced cytopathologist.

Abstract
Fine-needle aspiration cytology (FNAC) of the breast is a rapid, cost-effective, and sensitive procedure to diagnose breast lesions, and was widely employed to diagnose breast lesions in the past. However, in recent times, core needle biopsy of the breast is gaining popularity and acceptability, although FNAC still looms large. There are some intrinsic disadvantages to FNAC, of which the most important is probably difficulty in classification of a significant percentage of breast lesions. Such lesions are usually denoted by the rubric “grey zone lesions of the breast.” This article attempts to review these grey zone lesions and highlight the difficulties in diagnosing them.

Abstract
Diagnostic patterns in breast cancer have greatly changed over the past few decades, and core needle biopsy (CNB) has become a reliable procedure for detecting breast cancer without invasive surgery. To estimate the changing diagnostic patterns of breast cancer in urban Shanghai, 11,947 women with breast lesions detected by preoperative needle biopsy between January 1995 and December 2012 were selected from the Shanghai Cancer Data base, which integrates information from approximately 50% of breast cancer patients in Shanghai. The CNB procedure uses an automated prone unit, biopsy gun, and 14-gauge needles under freehand or ultrasound guidance and was performed by experienced radiologists and surgeons specializing in needle biopsies. Diagnosis and classification for each patient were independently evaluated by pathologists. Over the indicated 8-year period, biopsy type consisted of 11,947 ultrasound-guided core needle biopsies (UCNBs), 2,015 ultrasound-guided vacuum-assisted biopsies (UVABs), and 654 stereotactic X-ray-guided vacuum-assisted biopsies (XVABs). For all the 11,947 women included in this study, image-guided needle biopsy was the initial diagnostic procedure. Approximately 81.0% of biopsied samples were histopathologically determined to be malignant lesions, 5.5% were determined to be high-risk lesions, and 13.5% were determined to be benign lesions. The number of patients choosing UCNB increased at the greatest rate, and UCNB has become a standard procedure for histodiagnosis because it is inexpensive, convenient, and accurate. The overall false-negative rate of CNB was 1.7%, and the specific false-negative rates for UCNB, UVAB, and XVAB, were 1.7%, 0%, and 0%, respectively. This study suggests that the use of preoperative needle biopsy as the initial breast cancer diagnostic procedure is acceptable in urban Shanghai. Preoperative needle biopsy is now a standard procedure in the Shanghai Cancer Center because it may reduce the number of surgeries needed to treat breast cancer.

Abstract
INTRODUCTION Fine-needle aspiration cytology (FNAC) method is safe, reliable and time saving outdoor procedure with little discomfort to the patient for detecting Carcinoma breast. The efficacy can further be enhanced when physical breast examination, mammography and FNAC (the triple test [TT]) are jointly taken into consideration. AIMS AND OBJECTIVES The aim was to evaluate the role of TT score (TTS) in palpable breast masses. MATERIALS AND METHODS This prospective study was carried out from May 2010 to April 2012. In the subjects referred to the Department of Pathology for FNAC of the breast mass, the TTS was calculated, and histopathological findings were noted. RESULTS In the study period TTS score was calculated in 200 cases out of 225 FNAC's of breast. Of 124 benign cases on cytology, only three showed discordant TTS. Out of 62 malignant cases, 61 showed concordant TTS and one case of mastitis on histopathology showed TTS of five. Out of all the benign lesions, two cases of fibrocystic disease and a single case of phylloides tumor gave a TTS ≥6. These cases were diagnosed as infiltrating ductal carcinoma and angiosarcoma respectively on histopathology. Histopathological correlation was possible in only 70 patients. Of these 70, 28 were from the benign category and 42 were from the malignant category. TTS of ≥6 has a sensitivity of 97.44%, specificity of 100%. FNAC has a sensitivity of 88.37%, specificity of 96.42%. CONCLUSIONS TT reliably guides evaluation of palpable breast masses. Histological correlation indicated TTS to be better diagnostic tool than FNAC alone.

Abstract
INTRODUCTION Benign as well as malignant breast lesions are quite common in Indian population. It is the second most common cancer site after cancer cervix. Fine-needle aspiration cytology (FNAC) is safe, reliable, and time saving outdoor procedure with little discomfort to the patient. FNAC is useful in diagnosis and further planning of treatment without need for biopsy. The current study was carried out with aims of studying the frequency of various breast lesions on FNAC in a rural area in India and its histopathological correlation. MATERIALS AND METHODS This was 2 years prospective study carried out from May 2010 to April 2012. Physical examination of breast mass by palpation was done. Smears were stained with May-Grunwald Giemsa and Papanicolaou stain. RESULTS Of the 225 cases, 131 were in the benign category and 65 belonged to the malignant category, while the cytology study of 13 cases was unsatisfactory. Seventy-six cases were available for histological correlation. Of 29 cytological benign cases, 26 were confirmed as benign, but 3 turned out to be malignant. Out of 36 cytological malignant cases, 35 were confirmed as malignant. FNAC was 88.37% sensitive and 96.42% specific in diagnosing malignant lesions. CONCLUSION Fine-needle aspiration cytology is a rapid and effective method for the primary categorization of palpable breast lumps into benign, malignant, atypical, suspicious, and unsatisfactory categories. Benign breast lesions are common than malignant lesions. Histological correlation indicated FNAC to be a good diagnostic tool.

Abstract
Fine-needle aspiration cytology (FNAC) is an established, highly accurate, and cost-effective method for diagnosing lesions in different organs, including the breast. The method is minimally invasive without unwanted side effects. FNAC forms part of the triple assessment of breast lesions. Despite some shortcomings of the reporting categories, FNAC as part of the triple assessment has proved its value in describing the findings most accurately. The diagnostic impact depends on experience of the operator, quality of preparation, and diagnostic skills of the cytopathologist. The highest accuracy is achieved at centers with a multidisciplinary approach. FNAC is often palpation guided from palpable breast masses, whereas ultrasonography guidance is more widely used on nonpalpable lesions. Inadequate sampling with FNAC is particularly seen in collagenous lesions and in submitted specimens sampled by physicians lacking experience with the FNAC procedure. A diagnostic biopsy is recommended when FNAC provides scant material. FNAC is considered to be a safe method for screening purposes, although moderately less sensitive than core needle biopsy. FNAC is most accurate when experienced cytopathologists are available to assess the adequacy of the aspirated material and advise on additional aspirations for ancillary tests when needed.

Abstract
Breast fine-needle aspiration biopsy (FNAB) by palpation is on the decline, due to its limitations in diagnostic accuracy, decreased sensitivity, and its replacement with core needle biopsy (CNB). Despite its decreasing utility, superficial fine-needle aspiration (FNA) in breast is still the main modality for evaluating metastatic lesions, recurrence, and axillary lymph node metastasis. New modalities including proteomic pattern expression and methylation profiling of breast lesions are other promising techniques that can be used as ancillary tests for refining the diagnosis of breast lesions using FNAB. Image-guided breast FNA proves to be a successful alternative with high sensitivity and specificity. In this review, the advantages, disadvantages, and inherent limitations of breast FNA and CNB, and new advanced techniques are discussed.

Abstract
BACKGROUND Non-operative pathology diagnoses constitute an essential part of the work-up of breast lesions. With fine needle aspiration (FNA) and core needle biopsy (CNB) both having unique advantages, there is an increasing acceptance of CNB. This paper aims to outline the scientific basis of this trend. Additionally, we provide an update on novel techniques that derive cytological specimens from CNB (i.e., touch imprint (TI) and core wash (CW) cytology) in an attempt to get the best of both worlds. METHODS In addition to using the authors' experience, we performed a search of the Medline database combining the search terms "breast cancer diagnosis", "core needle biopsy", "fine needle aspiration", "touch imprint cytology", "core wash cytology" and "complications". We defined a conclusive non-operative diagnosis as "malignant" in lesions that were malignant on follow-up and "benign" in lesions that were benign on follow-up. RESULTS CNB was more often conclusive than FNA in benign and malignant lesions in 4 prospective studies. Although the more rapid diagnoses by FNA result in less patient anxiety during diagnostic work-up, CNB allows for fairly reliable estimation of invasion, histological type, grade, and receptor expression. CW and TI cytology seem promising techniques with conclusiveness rates that are roughly comparable to that of FNA. CONCLUSIONS All new suspicious breast lesions require careful non-operative investigation by CNB. However, additional cytological assessment by FNA can still be useful as a same-day diagnosis decreases patient anxiety and facilitates surgical treatment planning. TI and CW cytology techniques are promising same-day diagnosis modalities.

Abstract
Over the past decade, core biopsy rapidly replaced fine needle aspiration (FNA) in evaluation of diseases of the female breast in many centers in the USA. The inability to diagnose invasive cancer by FNA, and the general feeling of unease in interpretation of cytologic specimens among pathologists who are not trained in cytopathology are among factors leading to decline in the use of FNA. At our institution, we continue to rely heavily on FNA for evaluation of breast masses. In this article, we discuss our multidisciplinary team approach which is essential in sustaining a successful breast cancer screening program. We also review the general utility of breast FNA and core biopsy in a comparative fashion. In the second part of this article which will appear in an upcoming issue, we will review the use of FNA and core biopsy in challenging breast lesions focusing on the pitfalls and limitations of both modalities in selected specific lesions.

Abstract
A new "rapid cell block" technique (RCB; the predecessor of Cellienttrade mark Automated Cell Block System) is efficient at recovering sparse material. We previously found that RCBs of breast fine-needle aspirations (FNAs) frequently allow histologic classification of problematic ductal proliferative lesions. Previous studies that did not emphasize cell blocks found that on-site evaluation (OSE) of breast FNAs improves diagnosis. The purpose of this study was to determine if RCB could replace the utility of OSE of breast FNAs. The study included 604 consecutive ultrasound-guided noncyst breast FNAs composed of three cohorts based on the presence or absence of immediate adequacy assessment, conventional (collodion bag) cell blocks (CCB), and RCB. The cohort with OSE together with CCB did not perform as well as the cohort without OSE but with RCB. In a third cohort, performance characteristics of RCBs and CCBs were compared in an independent review by two cytopathologists blinded to the final cytology and follow-up histology diagnosis. By itself, the RCB histologic section was diagnostic 97% of the time, and it provided a diagnostic accuracy superior to CCB by itself and comparable to that provided by the combination of the smears with CCB. Highest accuracy was obtained by combining smears/monolayer preparations and RCB. Replacing OSE with RCBs provided substantial cost savings and savings of time for cytopathologists, radiologists, and their assistants.

Abstract
BACKGROUND Fine-needle aspiration cytology (FNAC) of both palpable and non-palpable breast carcinomas has a high accuracy and sensitivity in dedicated centres. It is generally thought that low-grade carcinomas have a distinctly lower sensitivity due to discrete cellular atypia that may be difficult to appreciate. Grade 1 carcinomas make up about 45% of screening-detected breast carcinomas and about 20% of symptomatic breast cancers. The aim of this study was to evaluate the diagnostic sensitivity of grade 1 carcinomas and identify the critical features in the cytological diagnostic work-up of these tumours. METHODS There were FNAC smears from 494 histologically confirmed grade 1 carcinomas diagnosed during 1996-2004. The cytological diagnoses were compared with the histology. RESULTS A definitive malignant diagnosis (absolute sensitivity) was given in 382 cases (77.3%). Equivocal or suspicious diagnoses were given in 75 (15.2%), benign or probably benign (false negative) in 24 (4.8%). Thirteen cases (2.6%) were unsatisfactory. Complete sensitivity was 92.7%. Invasive ductal carcinomas comprised 81.3% of all cases; absolute sensitivity for these was 80.9%. Invasive lobular and tubular carcinomas comprised 7.3% and 5.9% of cases, respectively; absolute sensitivity for these diagnosis was 50.0% and 57.1%, respectively, significantly lower than for other subtypes (P <or= 0.0001) whereas the difference for complete sensitivity was less but still significant (P = 0.017). Absolute and complete sensitivities were lower for tumours less than 1 cm size compared with more than 1 cm (P <or= 0.00001). CONCLUSION Preoperative FNAC diagnosis of grade 1 breast carcinoma has a high sensitivity, especially in ductal carcinomas. Invasive lobular and tubular carcinomas were less likely to receive a definite preoperative diagnosis. The main reason for not reaching a definitive malignant diagnosis was sampling error due to small tumours less than 1 cm in diameter, irrespective of tumour subtype.

Abstract
Clinical mammography and needle biopsy are key tools for non-operative assessment of breast lesions. We evaluated the performance of all combined tests undertaken in Denmark in 2000. Clinical mammography and needle biopsy data were collected and linked to final cancer outcome, to determine sensitivity, specificity, and predictive values of clinical mammography, needle biopsy, and combined test. In 2000, 6709 combined tests were performed in 36 mammography clinics in Denmark. The combined test was consistently more sensitive than any single test, increasing the proportion of women correctly identified with breast cancer by 9% compared with clinical mammography alone. For concordant combined tests (i.e. either both benign or both malignant), specificity and positive predictive value were 100%, sensitivity was 99.1%, and positive predictive value was 99.6%. Therefore, Danish patients with a malignant concordant combined test can proceed directly to definitive surgery without fear of a false-positive diagnosis, and Danish women with a concordant benign combined test can omit surgery without fear of a false-negative diagnosis. In discordant cases, our results showed that any of the two tests with a suspicious or malignant result indicated a high risk of cancer, and excisional diagnostic biopsy therefore still has an important role to play.

Abstract
Evidence-based medicine (EBM) is a fashionable and an extremely hot topic for clinicians, patients and the health service planners. Evidence-based cytology (EBC) is an offshoot of EBM. The EBC is concerned with generating a reproducible, high quality and clinically relevant test result in the field of cytology. This is a rapidly evolving area with high practical importance. EBC is based entirely on research data. The various professional bodies on cytology design and recommend guidelines on the basis of evidences. Once the guideline is implemented and practiced then the experiences of the practicing cytopathologists may be used as a feed back to alter the existing guideline. The various facets of EBC are sampling and specimen adequacy, morphological identification and computer based expert system, integrated reporting, identification of the controversial areas and high quality researches for evidences. It is the duty of the individuals and institutions to practice EBC for better diagnosis and management of the patients. In this present paper, the various aspects of EBC have been discussed.

Abstract
BACKGROUND Numeric grading systems have been validated for the reporting of mammographic abnormalities and for breast cytology. The impact of integrating lesion grades from both disciplines on the accuracy of assessment of screen-detected lesions has not been investigated. METHODS In the current study, all lesions were prospectively classified using the Tabar radiologic grading system, as well as the National Health Service Breast Screening Programme (NHSBSP) cytologic reporting system. For lesions assessed between January 1996 and January 2003, based on final histology or 12 months of follow-up, positive predictive values (PPV) were calculated for each imaging grade and for each cytologic grouping. After integration of the data, changes in the PPV and the negative predictive values (NPV) of cytology among lesions with varying imaging grades were tracked. RESULTS Data were retrieved for 4806 lesions. The differences in the rates of malignancy for lesions in the different imaging grades were significant (Grade 5, 95.8%; Grade 4, 54.6%; Grade 3, 11.6%) (P < 0.001). Similarly, the cytologic categories stratified lesions into groups with significantly different rates of malignancy (positive, 99.5%; suspicious, 89.2%; atypical, 43.4%; benign, 5.7%; inadequate, 33.3%) (P < 0.001). Integration of cytologic results with the imaging grade of lesions led to significant improvements in the PPV and NPV. Positive smears were likely to represent malignant lesions in 99.9% of Grade 5 lesions, 99.2% of Grade 4 lesions, and 95.2% of Grade 3 lesions (P < 0.0001). Similarly, negative cytology corresponded to a nonmalignant lesion in 99% of Grade 3 lesions, 81.6% of Grade 4 lesions, and in only 45.5% of Grade 5 lesions (P < 0.001). CONCLUSIONS The integration of numeric grading schemes for breast imaging and cytology improves the accuracy of assessment of screen-detected lesions. Because 99.9% of Grade 5 lesions with positive cytology are malignant, core biopsy confirmation may not be required in this group.

Abstract
INTRODUCTION Fine-needle aspirates (FNAs) with scant cellularity are considered inadequate by current cytopathology standards. We hypothesized that such aspirates are clinically useful. METHODS A 10-year database of palpable breast lumps evaluated by FNA-based triple test (TT; FNA, breast imaging studies, and clinical breast examination) and triple test scores (TTSs; 3-9) was examined to identify FNAs with scant cellularity but without evidence of malignancy (negative SC-FNAs). These FNAs were correlated with the occurrence of any subsequent cancers (false-negative SC-FNAs) and with TTSs. RESULTS Among a total of 324 negative SC-FNAs, 9 cancers were subsequently found at sampled sites. Seven were associated with a suspicious or malignant TTS (scores of 5 or greater) and therefore still correctly diagnosed as malignant or suspicious for malignancy. The remaining two cancers were missed by both SC-FNA and TTS (false-negative rate for TTS of 0.6%); both had scores of 4 because of suspicious imaging. CONCLUSIONS Scantly cellular but negative FNAs are useful (can avoid unnecessary invasive breast biopsy) in the evaluation of palpable breast masses, especially when interpreted in the context of the TT and TTS.

Abstract
Lobular carcinoma in situ (LCIS) of the breast is a recognized marker for increased risk of invasive carcinoma and has well-established histologic criteria. However, its detection and diagnosis on FNA of breast has not been well defined. Cytology slides (all ThinPrep) of 11 cases with biopsy-proven LCIS at Beth Israel Deaconess Medical Center were reviewed. All 11 cases showed tight and/or loosely cohesive clusters of crowded mildly enlarged nuclei and ten of 11 showed at least moderate cellularity. Single epithelial cells, small but prominent nucleoli, intracytoplasmic lumina, and two distinct epithelial-cell populations were also noted in some cases. As none of these features is specific for LCIS, it would be prudent to report such lesions as atypical so that a core biopsy or excisional biopsy will be performed before definitive treatment. The original FNA diagnosis of the 11 cases ranged from epithelial proliferation without atypia to carcinoma. Three of the 11 cases had fibroadenomas on histology with extensive involvement by LCIS. Since management for LCIS is different from that for invasive carcinoma or DCIS, it should be considered and distinguished from the latter two in cases suspicious for carcinoma on FNA.

Abstract
BACKGROUND In 1996, the National Cancer Institute (NCI) recommended five categories for the diagnosis of breast aspiration cytology: benign, atypical, suspicious, malignant, and unsatisfactory. The authors evaluated the usefulness of separating inconclusive diagnoses into the aforementioned atypical and suspicious categories. The current study examined the correlation between cytologic and histologic findings made in breast aspiration cytology specimens that were categorized in accordance with these NCI guidelines. METHODS From 1992 to 2000, 7727 breast aspirations were performed at the University of Miami/Jackson Memorial Medical Center (Miami, FL). Aspirates were classified using criteria similar to the NCI recommendations. Four hundred eighty-nine aspirates (6%) were classified as being cytologically 'atypical' or 'suspicious'. Of those, 225 'atypical' aspirates and 162 'suspicious' aspirates had available histologic follow-up data and were included in the study. RESULTS Among the 'atypical' aspirates, 118 (52%) yielded malignant findings on histologic evaluation. Infiltrating ductal carcinoma (n = 87; 74%) was the most common malignant diagnosis, followed by infiltrating lobular carcinoma (n = 12; 10%). Among 'suspicious' aspirates, 135 (83%) yielded malignant findings on histologic analysis. The most common benign diagnosis in both 'atypical' and 'suspicious' aspirates was proliferative fibrocystic changes with or without atypia, followed by fibroadenoma. CONCLUSIONS Most aspirates that yielded suspicious findings on cytologic examination proved to be malignant, as did > 50% of aspirates that yielded atypical findings. Infiltrating lobular carcinoma commonly was underdiagnosed as being atypical on cytologic examination. Benign lesions with atypical or suspicious cytologic diagnoses included certain cases of atypical ductal hyperplasia. The authors concluded that the distinction between the atypical and suspicious categories, as recommended by the NCI, is not warranted. Therefore, they suggest the use of a single term, such as 'equivocal', to describe inconclusive diagnoses on breast fine-needle aspiration cytology.

Abstract
To determine the effect of stereotactic core-needle biopsy (SCNB) on the utilization of breast fine-needle aspirate (FNA) biopsy, we retrospectively reviewed 1,568 cases of breast FNAs that were obtained from 1,188 patients between the years 1990 and 2000. There were 378 positive and atypical cases and 497 negative and unsatisfactory cases in the pre-SCNB group (between 1990 and 1996; 7 years); and 225 positive and atypical cases and 468 negative and unsatisfactory cases in the post-SCNB group (between 1997 and 2000; 4 years). The average number of cases per year in the pre- and post-SCNB groups was 125 and 173, respectively. While the average positive/atypical cases per year in both groups remained relatively constant, the average negative/unsatisfactory cases per year were significantly increased in the post-SCNB group (117 in the post-SCNB vs. 71 in the pre-SCNB). The increase in this group was due to a true increase in the negative diagnoses, since unsatisfactory rate decreased in the post-SCNB group (12.6% in the post-SCNB vs. 9.3% in the pre-SCNB). The sensitivity, specificity, positive predictive value, and negative predictive value were 90%, 79%, 92%, and 82% in the pre-SCNB group and 93%, 86%, 91%, and 90% for the post-SCNB group, respectively. In conclusion, the implementation of SCNB did not result in a decrease in the total number of breast FNAs; however, the distribution of cases changed. FNA is increasingly used to complete the triple test in clinically and radiographically negative cases.

Abstract
The diagnosis of atypia in breast fine-needle aspiration (FNA) continues to be an area of debate in cytology practice. The aim of this study was to assess the clinical significance of this term and to evaluate potential morphological criteria, which would determine the patient's outcome. A computer-based search was carried out to retrieve breast FNAs performed between 1990 and 2000 that were diagnosed as atypical. Cases followed by surgical resection were reexamined for the presence of morphological features potentially differentiating benign and malignant lesions. Out of 1,568 breast FNAs, there were 64 cases (4%) with a diagnosis of atypia. Thirty-eight cases had surgical follow-up material that revealed malignancy in 14 cases (37%) and benign lesions in 24 cases (63%). The benign diagnostic categories included fibrocystic change (12/24), fibroadenoma (3/24), tubular adenoma (2/24), and nonspecific findings (7/24). The malignant diagnoses included ductal carcinoma (9/14), lobular carcinoma (3/14), ductal carcinoma in situ (DCIS; 1/14), and tubular carcinoma (1/14). The evaluation of cytological criteria used to differentiate benign from malignant lesions (i.e., cellularity, loss of cohesion, myoepithelial cells, nuclear enlargement, nuclear overlap, prominent nucleoli) revealed significant overlap between benign and malignant cases, particularly in cases of fibroadenoma, tubular adenoma, and proliferative breast disease. The surgical follow-up of four hypocellular cases revealed lobular carcinoma in two cases and ductal carcinoma in the remaining two cases. Our study confirmed that the diagnosis of atypia is clinically significant because it is associated with a high probability of malignancy. No morphological criterion is able to reliably differentiate benign and malignant lesions in cases diagnosed with atypia. Diagnosis of atypia is particularly significant in hypocellular cases. We recommended that breast FNAs with a diagnosis of atypia be evaluated further histologically.

Abstract
The use of ultrasound-guided fine-needle aspiration (FNA) biopsy for nonpalpable breast lesions varies considerably. This retrospective study stresses the role of breast FNA in evaluating sonographically suspicious nonpalpable breast masses using a probabilistic reporting system. One hundred and eight consecutive ultrasound-guided FNA biopsies diagnosed as positive (32), suspicious (8), atypical (11), benign (55), and unsatisfactory (2) were analyzed and correlated with 61 subsequent surgical specimens. All positive cytologies showed carcinoma on histology; suspicious cases were followed by 5 carcinomas, 2 fibroadenomas, and 1 papillary lesion. Follow-up of atypical cases included 4 carcinomas, 3 fibroadenomas, and 2 papillary lesions, while all 10 biopsies following benign cytology showed fibrocystic changes. Two cases with suspicious sonographic findings but unsatisfactory cytology had lobular carcinoma. The remainder of the benign and atypical cases were followed clinically and radiographically for at least 10 months and had no evidence of carcinoma. Positive predictive values were positive, 100%; suspicious, 63%; atypical, 36%; benign, 0%. Most (40/43; 93%) carcinomas were invasive. In conclusion, ultrasound-guided FNA for nonpalpable breast lesions is highly accurate, and probabilistic reporting helps direct patient management.

Abstract
Fine-needle aspiration cytology (FNAC) is an established, highly accurate method for diagnosing breast lesions. However, in recent years there has been increased use of core biopsy (CB) in this setting. The aim of this study was to evaluate the accuracy of FNAC and compare the quality assessment parameters of FNAC and CB in palpable and nonpalpable breast lesions. Data regarding FNAC, CB, and excision biopsy (EB) diagnoses were retrieved from the archives of our department. A total of 4,367 FNAC samples from the years 1999-2001 was reviewed. Of these, corresponding histology results were available for 1,275 lesions, of which 1,248 were primary breast epithelial lesions (788 EB, 199 CB, 261 EB+CB). All cases were analyzed for sensitivity and specificity of FNAC. Cases with both FNAC and CB were compared and quality assessment parameters were calculated using the methodology detailed in the National Health Service Breast Screening Program guidelines. High specificity and sensitivity, as calculated for satisfactory specimens, were achieved with the use of both FNAC and CB. False-positive and false-negative diagnoses were seen in 7/404 (1.7%) and 45/635 (7.1%) of biopsy-proven specimens sampled by FNAC. The corresponding values for CB were 0% and 5.7%, respectively. Inadequate sampling (15.1%) with use of FNAC was particularly seen in collagenous lesions and in submitted specimens sampled by physicians lacking experience with the FNAC procedure. FNAC is a valuable method, although moderately less sensitive than CB. CB is the preferred method for preoperative diagnosis when sampling FNAC provides scarce material and suspicion of a fibrotic and collagenous lesion such as lobular carcinoma and radial scar arises. FNAC is most accurate when experienced cytologists are available and when immediate assessment by professionals is performed for evaluation of material adequacy, so that additional aspirations can be done when needed.

Abstract
BACKGROUND Fine-needle aspiration biopsy (FNAB) has been used with variable success as a diagnostic test for benign and malignant breast lesions. The goal of this study was to examine the effects of training physicians in the fine-needle aspiration sampling-technique on the diagnostic accuracy of FNAB of palpable breast masses. The settings for this study were private physicians' offices and university clinics of primary care physicians, surgeons, and cytopathologists. METHODS We reviewed 1043 consecutive FNAB specimens of the breast obtained during 1 year (1992): 729 FNABs were performed by formally trained physicians (at least 150 FNABs performed previously under supervision during fellowship training or the equivalent) who had done at least 100 FNABs during the year; 314 FNABs were performed by physicians without formal training who had done a median of only 2 FNABs during the year (range, 1-43 FNABs). All FNAB specimens were reviewed microscopically and evaluated for cellularity and type of material present, for diagnostic accuracy, and for the rate of surgical intervention. A minimum of 2 years of follow-up was obtained by matching all cases to the population-based Northern California Cancer Registry. FNAB specimens were correlated with histologic specimens when they were available. RESULTS Using FNAB, the formally trained physicians missed 2% of cancers, whereas the physicians without formal training missed 25%. Among the patients with benign lesions seen by the formally trained physicians, 8% went on to surgery, whereas 30% of those seen by physicians without formal training did so. Specimens obtained by the formally trained physicians were significantly more cellular and were significantly less likely to be nondiagnostic. CONCLUSIONS FNAB, when performed by physicians who are well trained in the technique, is a highly accurate, cost-effective diagnostic method that carries minimal morbidity and could replace a large number of surgical biopsies. When performed by physicians without adequate training, FNAB is often misleading and potentially harmful.
