Abstract
Background Oral cavity is the most prevalent site of head and neck squamous cell carcinomas (HNSCCs). Most often diagnosed at a locally advanced stage, treatment is multimodal with surgery as the cornerstone. The aim of this study was to explore the molecular landscape of a homogenous cohort of oral cavity squamous cell carcinomas (OCSCCs), and to assess the prognostic value of tumor mutational burden (TMB), along with classical molecular and clinical parameters. Patients and methods One hundred and fifty-one consecutive patients with OCSCC treated with upfront surgery at the Institut Curie were analyzed. Sequencing of tumor DNA from frozen specimens was carried out using an in-house targeted next-generation sequencing panel (571 genes). The impact of molecular alterations and TMB on disease-free survival (DFS) and overall survival (OS) was evaluated in univariate and multivariate analyses. Results Pathological tumor stage, extranodal spread, vascular emboli, and perineural invasion were associated with both DFS and OS. TP53 was the most mutated gene (71%). Other frequent molecular alterations included the TERT promoter (50%), CDKN2A (25%), FAT1 (17%), PIK3CA (14%), and NOTCH1 (15%) genes. Transforming growth factor-β pathway alterations (4%) were associated with poor OS (P = 0.01) and DFS (P = 0.02) in univariate and multivariate analyses. High TMB was associated with prolonged OS (P = 0.01 and P = 0.02, in the highest 10% and 20% TMB values, respectively), but not with DFS. Correlation of TMB with OS remained significant in multivariate analysis (P = 0.01 and P = 0.005 in the highest 10% and 20% TMB values, respectively). Pathological tumor stage combined with high TMB was associated with good prognosis. Conclusion Our results suggest that a high TMB is associated with a favorable prognosis in patients with OCSCC treated with upfront surgery. High TMB is associated with a favorable prognosis in patients with OCSCC treated with upfront surgery Pathological tumor stage combined with high TMB is associated with good prognosis TP53 was the most mutated gene (71%). Other frequent molecular alterations included the TERT promoter (50%) TGFβ pathway alterations were associated with poor outcomes, although it was only observed in 4% of the patients

Abstract
OBJECTIVES According to the Renal Tumor Study Group (RTSG) of the International Society of Paediatric Oncology (SIOP), diagnostic biopsy of renal tumors prior to neoadjuvant chemotherapy is not mandatory unless the presentation is atypical for a Wilms tumor (WT). This study addresses the relevance of this strategy as well as the accuracy and safety of image-guided needle biopsy. METHODS Clinical, radiological, and pathological data from 317 children (141 males/176 females, mean age: 4 years, range, 0-17.6) consecutively treated in one SIOP-affiliated institution were retrospectively analyzed. RESULTS Presumptive chemotherapy for WT was decided for 182 patients (57% of the cohort), 24 (8%) were operated upfront, and 111 (35%) were biopsied at diagnosis. A non-WT was confirmed after surgery in 5/182 (3%), 11/24 (46%), and 28/111 (25%), respectively. Age at diagnosis was the most commonly (46%) used criterion to go for biopsy but a nine-year threshold should be retrospectively considered more relevant. Tumor volumes of clear cell sarcoma of the kidney and WT were significantly higher than those of other tumors (P = 0.002). The agreement between core-needle biopsy (CNB) and final histology was 99%. No significant morbidity was associated with CNB. CONCLUSION The use of SIOP criteria to identify patients eligible for presumptive WT neoadjuvant chemotherapy or upfront surgery avoided biopsy in 65% of children and led to a 97% rate of appropriate preoperative chemotherapy. Image-guided CNB is a safe and accurate diagnostic procedure. The relevance of SIOP biopsy criteria might be improved by using an older age threshold (9 years instead of 6 years) and by adding initial tumor volume.

Abstract
BACKGROUND We aimed at identifying deleterious genomic alterations from untreated head and neck squamous cell carcinoma (HNSCC) patients, and assessing their prognostic value. PATIENTS AND METHODS We retrieved 122 HNSCC patients who underwent primary surgery. Targeted NGS was used to analyse a panel of 100 genes selected among the most frequently altered genes in HNSCC and potential therapeutic targets. We selected only deleterious (activating or inactivating) single nucleotide variations, and copy number variations for analysis. Univariate and multivariate analyses were performed to assess the prognostic value of altered genes. RESULTS A median of 2 (range: 0-10) genomic alterations per sample was observed. Most frequently altered genes involved the cell cycle pathway (TP53 [60%], CCND1 [30%], CDKN2A [25%]), the PI3K/AKT/MTOR pathway (PIK3CA [12%]), tyrosine kinase receptors (EGFR [9%], FGFR1 [5%]) and cell differentiation (FAT1 [7%], NOTCH1 [4%]). TP53 mutations (p = 0.003), CCND1 amplifications (p = 0.04), CDKN2A alterations (p = 0.02) and FGFR1 amplifications (p = 0.003), correlated with shorter overall survival (OS). The number of genomic alterations was significantly higher in the HPV-negative population (p = 0.029) and correlated with a shorter OS (p < 0.0001). Only TP53 mutation and FGFR1 amplification status remained statistically significant in the multivariate analysis. CONCLUSION These results suggest that genomic alterations involving the cell cycle (TP53, CCND1, CDKN2A), as well as FGFR1 amplifications and tumour genomic alterations burden are prognostic biomarkers and might be therapeutic targets for patients with HNSCC.

Abstract
Whereas neuroblastoma (NB) with MYCN amplification presents a poor prognosis, no single marker allows to reliably predict outcome in tumours without MYCN amplification. We report here an extensive analysis of 147 NB samples at diagnosis, without MYCN amplification, by chromosomal comparative genomic hybridisation (CGH), providing a comprehensive overview of their genomic imbalances. Comparative genomic hybridisation profiles showed gains or losses of entire chromosomes (type 1) in 71 cases, whereas partial chromosome gains or losses (type 2), including gain involving 17q were observed in 68 cases. Atypical profiles were present in eight cases. A type 1 profile was observed more frequently in localised disease (P<0.0001), and in patients of less than 12 months at diagnosis (P<0.0001). A type 2 genomic profile was associated with a higher risk of relapse in the overall population (log-rank test; P<0.0001), but also in the subgroup of patients with localised disease (log-rank test, P=0.007). In multivariate analysis, the genomic profile was the strongest independent prognostic factor. In conclusion, the genomic profile is of prognostic impact in patients without MYCN amplification, making it a help in the management of low-stage NB. Further studies using higher-resolution CGH are needed to better characterise atypical genomic alterations.

Abstract
BACKGROUND The study was designed in order to evaluate the degree of correlation of mitotic index (MI), Ki67 (MIB1) score and S-phase fraction (SPF) as markers of cell proliferation and prognosis in breast cancer. MATERIALS AND METHODS The series analysed corresponded to 257 consecutive invasive breast carcinoma, treated at the Institut Curie, France, in 1995. Nottingham histological grade and MIB1 semiquantitative and quantitative score were assessed on histological sections, whereas SPF was calculated using flow cytometry analysis of fine-needle aspiration products. Proliferation indices were compared to pathological data and to overall survival (OS) and disease-free survival (DFS) (minimum follow-up: 72 months). RESULTS The median values for the proliferation markers were 9/10 HPF for MI, 32.4% for MIB1 and 3.7% for SPF. A high rate of correlation (r=0.96; p<0.001) was observed between semi-quantitative and quantitative MIBI evaluation. A positive correlation was found between the three markers (r ranging from 0.54 to 0.61;p<0.001). Univariate analysis of markers associated to disease outcome showed that MIB1, axillary node status (N) and progesterone receptor (PR) status were significantly associated with OS and that MIB1 and SPF were associated with DFS, together with node and hormone receptor status. In multivariate analysis, when proliferation markers were adjusted on the N and PR status, only MIB1 retained a prognostic value for OS (RR= 1.83) [1.00;3.35] and SPF for DFS (RR= 1.58) [1.02-2.44] (p=0.04). CONCLUSION A good level of correlation was observed between the values of the three markers of tumour cell proliferation analysed. In this series of invasive breast cancers, MIB1 immunostaining was found to be a prognostic marker of both OS and DFS. The median (32.4%) was a valuable cut-off value for prognostic assessment. Semi-quantitative and quantitative evaluations provided very similar values. MIB1 can thus be considered as a reliable prognostic maker, usable in small size tissue specimens which are inappropriate for MI or SPF analysis. The impact of MIB1 compared to that of the other proliferative markers will be further assessed in a subgroup of T1N0M0 for which the prognostic assessment is of major interest.

Abstract
BACKGROUND Desmoplastic small round cell tumor (DSRCT) is a recently described neoplasm. This entity is well defined, with distinct clinical, pathologic and immunohistochemical features. Molecular studies have shown a specific reciprocal translocation t(11;22)(p13;q12). To our knowledge, no report of DSRCT with molecular confirmation on cytologic material has been reported before. CASE Fine needle aspiration (FNA) was performed on an intraabdominal mass in a 37-year-old man. A May-Grunwald-Giemsa-stained preparation showed clusters of small round tumor cells associated with desmoplastic stromal cells, highly suggestive of DSRCT. FNA of a supraclavicular node showed cytologic features similar to those of the primary abdominal mass, including a prominent desmoplastic reaction of the stroma. Immunocytochemical studies showed myogenic and epithelial differentiation. Molecular analysis was performed on FNA, revealing the EWS/ WT1 chimeric transcript and thus confirming the cytologic diagnosis. CONCLUSION Cytomorphologically, a definitive diagnosis of DSRCT may be difficult, as this tumor bears considerable resemblance to other small round cell tumors. The diagnosis can be confirmed by ancillary techniques, such as immunocytochemistry, and particularly by molecular analysis, which may also be performed on cytologic material.

Abstract
The assessment of apoptosis in solid tumors is of interest because of its biological role in tumor evolution and response to therapy. A commonly used method for apoptosis measurement is the TUNEL 3' end-labeling technique, which has shown wide variations in results when applied to solid tumors. Thirty-one fine needle breast carcinoma samples were analyzed by fluorescent TUNEL assay and DNA content using image analysis and flow cytometry. TUNEL positivity, seen both in cells with apoptotic morphology and in a subset of morphologically normal cells, was categorized into five staining patterns and quantitated. Values for patterns of TUNEL-positive cells were compared with TUNEL positivity measured by flow cytometry. Flow cytometric quantitation showed a mean of 24.3% positive cells, which correlated (P < 0.02) with total positive cells (all patterns) measured by image (22.4%). Image analysis quantitation of morphologically apoptotic cells (4.2%) did not correlate with flow cytometric TUNEL positivity and the majority of TUNEL-stained cells were morphologically normal (17%). Image analysis allows discrimination of TUNEL-positive morphologically apoptotic and nonapoptotic cells, which are included in the total number of TUNEL-positive events measured by flow cytometry.

Abstract
BACKGROUND Because false-positive cytologic diagnoses in breast tumors are rare, few cases have been reported, although their consequences may be highly detrimental to the patient. The authors report the Institut Curie's experience, by using a multidisciplinary approach. METHODS Of 9334 benign breast tumors examined preoperatively for cytologic diagnosis by fine-needle sampling (FNS), the 23 (0.25%) FNS cases considered to be false-positive were retrospectively reviewed and analyzed. RESULTS Tumors were situated close to the nipple in 7 cases and away from the nipple in 16 cases. Tumor stage was T0 for 1 case, T1 for 18 cases, and T2 for 4 cases. Radiologically, six tumors were classified as malignant, seven as indeterminate or suspicious, and nine as benign. Three of six tumors studied by flow cytometry were DNA aneuploid. Based on a multidisciplinary clinicopathologic review, 20 FNS cases were finally classified as false-positive, and the remaining 3 tumors with malignant FNS and subsequent benign histology were classified as true-positive, because local and/or metastatic progression was observed in the short term. CONCLUSIONS The authors' review suggests two categories of false-positive cases: the first in which cytologic benign patterns are overdiagnosed, and the second in which atypical morphologic criteria were present. Nevertheless, as shown by the malignant course in three cases, patients with malignant preoperative FNS and corresponding benign histology always require close clinical follow-up. Finally, surgical overtreatment rate could be decreased if all radiologically benign tumors with positive/suspicious FNS were subject to intraoperative frozen section examination.

Abstract
Fine-needle samplings of nine examples of primary neuroendocrine carcinoma of salivary glands were evaluated for their cytologic characteristics and were correlated with the corresponding histological sections. Consistent cytological findings were dispersed or loose clusters of poorly differentiated small- to intermediate-sized cells and occasional smudged nuclei. Mild to moderate nuclear pleomorphism, scant or absent cytoplasm, and nuclear molding were also observed. Rosette-like patterns and multinucleated cells were occasionally seen. Immunostaining of one recent case showed positivity for chromogranin and keratin. The differential diagnosis of primary and metastatic tumors with neuroendocrine features of the salivary glands is discussed.

Abstract
BACKGROUND Metastatic tumors to the salivary glands are common, but documentation in the cytologic literature has been limited. The current study presents the authors' experience with fine-needle aspiration (FNA) in metastatic nonlymphomatous tumors to the salivary glands. METHODS From a retrospective review of 1675 salivary gland lesions (1535 patients), the authors collected 40 salivary gland lesions (39 patients who had histories of extrasalivary cancer) that were diagnosed cytologically as metastases to the salivary glands and were correlated histologically. RESULTS FNAs of 34 parotid gland and 6 submandibular gland tumors were performed. The cytologic diagnoses of metastases of squamous cell carcinoma (15 cases), melanoma (12 cases), carcinoma (5 cases), rhabdomyosarcoma (3 cases), and retinoblastoma (2 cases) were confirmed (95%) histologically. Two (5%) FNAs were false-negative. CONCLUSIONS In patients who had a history of extrasalivary cancer, cytology examination was very helpful and sufficient for adequate patient management.

Abstract
The rates of cell proliferation and programmed cell death (apoptosis) reflect tumor cell dynamics and are considered to directly influence biological progression and tumor response to therapy. Bax and Bcl-2 are members of a gene family that influence apoptosis and have been used as surrogate markers in the evaluation of this process. Sixty-three fine-needle tumor samples from an equal number of patients with breast carcinomas were analyzed for Bax, Bcl-2, and DNA content by flow cytometry. The results were correlated with classical clinicopathological parameters. Bax values varied widely among tumors and showed no significant correlation with any of the clinicopathological parameters analyzed. Bcl-2 levels ranged from 4% to 91%, correlated positively with estrogen (P = 0.0004) and progesterone (P = 0.0045) receptor positivity, and were more associated with low S-phase tumor values. In contrast, high S-phase values correlated with estrogen receptor negativity, high grade, and DNA aneuploidy. The study results indicate that Bcl-2 and S-phase analysis of fine-needle samples of breast carcinomas provide a convenient tool for the assessment of these tumors.

Abstract
PURPOSE The aim of this study was to assess the diagnostic accuracy of sonography alone and combined sonographic assessment and sonographically guided fine-needle aspiration cytology in solid, nonpalpable lesions of the breast. METHODS We retrospectively evaluated the sonograms from a series of 174 consecutive nonpalpable masses that were cytologically diagnosed using fine-needle aspiration under sonographic guidance and then histologically verified through surgical excision. We examined the relationships between the findings from sonography, combined sonographic assessment and cytopathology, and histology. RESULTS Histologically, 95 lesions (55%) were malignant and 79 (45%) were benign. The overall sensitivity of sonography alone for diagnosing cancer was 98. 9% (94 of 95 lesions), and the specificity was 45.6% (36 of 79 lesions). One (3%) of 37 masses considered at sonography to be benign was correctly diagnosed on cytologic examination to be cancer. By establishing the benign status of 11 of 13 masses that were indeterminate at sonography, cytology increased the specificity of the combined method (to 56.3%). Cytology appropriately suspected or confirmed malignancy in 79 (84%) of 94 carcinomas considered at sonography to be suspicious or malignant. CONCLUSIONS In this study, sonography alone demonstrated a high sensitivity but limited specificity in evaluating nonpalpable breast masses. The addition of sonographically guided cytology substantially increased the specificity of the combined method without compromising sensitivity.

Abstract
The OGG1 gene, which codes for a DNA repair protein with antimutator activity, is located on chromosome 3p25, a frequent site of allelic deletions in many types of human tumors, including renal clear cell cancers. We present the analysis of 99 renal tumors for alterations in the OGG1 gene to determine its association with tumorigenesis. Loss of heterozygosity in the 3p25 region was found for 85% of the informative cases. We detected somatic missense mutations of the OGG1 gene in 4 of the 99 tumor samples. Biochemical analysis of the mutant proteins revealed that a substitution at codon 46 impairs the enzymatic activity. We also describe the occurrence of several polymorphisms as well as aberrantly spliced OGG1 transcripts.

Abstract
BACKGROUND Fine-needle sampling, although a practical and noninvasive method of tissue acquisition, has rarely been used for HER-2/neu fluorescent in situ hybridization (FISH). To assess HER-2/neu gene amplification in mammary carcinoma, FISH signals on cytology and corresponding tissue biopsies were detected visually and measured by image analysis. The results were correlated with patient and tumor characteristics. METHODS In situ HER-2/neu DNA probe hybridization was performed on 61 cytology specimens and on 47 corresponding frozen sections of breast carcinomas. Tumors were classified by visual evaluation as unamplified, moderately amplified, or highly amplified. Multiparametric image analysis was performed using the Discovery automated image analyzer (Becton Dickinson, Leiden, Netherlands). The integrated fluorescence ratio (IFR) was calculated for each sample as the integrated FISH fluorescence of the tumor cells divided by the integrated FISH fluorescence of internal control cells containing two spots. The percentage positive nuclear area (PPN), calculated as the area of FISH fluorescence divided by the area of nuclear DNA fluorescence, and the PPR, ratio of the PPN of the tumor cells divided by the control cells, were also calculated for each sample. RESULTS Visual analysis yielded 46 unamplified and 15 (24.6%) amplified (seven moderately amplified and eight highly-amplified) tumors. Strong (P < 0.001) correlation between results on cytological and histological materials was obtained. The FISH spots on the cytological preparations were more easily visualized and scored than those on the corresponding tissue sections. Visual HER-2/neu signal scoring was strongly correlated with IFR (P = 0.0001) and PPR (P = 0.0001). Within the tumors classified as highly amplified by visual examination, quantitation of the degree of amplification fluorescence signal was possible using image analysis. CONCLUSIONS Cytologic specimens were a suitable and representative source of materials for detection and quantitation of HER-2/neu gene amplification by FISH and image analysis.

Abstract
Preoperative fine-needle samplings (FNS) of 26 histologically proven carcinoma ex pleomorphic adenomas (24 primary tumors and 2 local recurrences in 24 patients) were retrospectively reviewed in order to evaluate their cytologic characteristics. Histologically, 17 were high-grade and 9 were low-grade carcinomas; 10 carcinomas were intratumoral (in situ), and 16 were infiltrative. A cytologic diagnosis of malignancy was established in 13 (50%) cases, 2 (7.7%) were suspicious, and 11 (42.3%) were negative for malignancy (10 pleomorphic adenomas, 1 inflammation). The majority (76.5%) of high-grade carcinomas were correctly diagnosed by FNS, regardless of invasiveness. Paradoxically, most (77.8%) negative results were encountered in low-grade carcinomas. Accurate diagnosis of malignancy on FNS is achieved in high-grade tumors and low sensitivity may cause interpretative difficulties in low-grade tumors. Diagn. Cytopathol. 1999; 21:163-166.

Abstract
BACKGROUND Restricted presentation of malignancy at both lacrimal and parotid salivary glands are unusual occurrences that may pose clinical and diagnostic difficulties. METHODS We applied certain clinicopathological criteria to distinguish between lacrimal and parotid gland primaries in a series of 11 patients with synchronous and/or metachronous tumors of similar histology at both sites. RESULTS Of eight patients with primary lacrimal carcinomas, seven had metachronous metastases to parotid glands. All three patients with primary parotid carcinomas had concurrent metastases to lacrimal glands. Patients with primary lacrimal tumors metastasizing to the parotid gland appear to have better clinical outcome in comparison with those with parotid primary with secondary lacrimal metastases. CONCLUSION Careful examination of parotid glands in the assessment of any lacrimal gland tumor with high-grade adenocarcinoma morphology is recommended to rule out the possibility of a parotid primary.

Abstract
Cytologic results of preoperative fine-needle sampling (FNS) of 15 salivary basal-cell tumors are presented, described, and compared with histologic results. Eleven of the FNAS showed individual and clusters of homogeneous basaloid cells with scanty cytoplasm, occasional peripheral palisading, and naked nuclei and were diagnosed as basal-cell adenoma. Four samples showed, in addition, three-dimensional cell clusters with mild cytonuclear atypia, occasional mitosis, and/or focal necrosis and were diagnosed as basal-cell adenocarcinoma. Basal-cell tumors must be diagnostically differentiated from adenoid cystic carcinoma and metastatic basal-cell carcinoma. Although the adenomas diagnosed by cytologic examination and four suspected carcinomas in our series were verified by histologic testing, the bland cytologic features of basal-cell adenocarcinoma may not always allow diagnosis on cytologic examination.

Abstract
Fine-needle sampling (FNS) of five cases of epithelial-myoepithelial carcinoma, three primary tumors, and two local recurrences, was performed preoperatively in five patients. Cytologic diagnoses of malignancy were established in all tumors (three were reported as adenoid cystic carcinoma, two as adenocarcinoma not otherwise specified). Material for cytologic evaluation was satisfactory in all cases. Adenoid cystic carcinoma, polymorphous low-grade adenocarcinoma, papillary cystadenocarcinoma and cellular type of pleomorphic adenoma are the main differential diagnoses.

Abstract
Fine-needle samplings (FNS) of 21 salivary duct carcinomas, histologically correlated, including 19 primaries, one local recurrence, and one lymph node metastasis from 19 patients, are reported. Cytologic diagnosis of high-grade adenocarcinoma was established in 15 (71%). Five (24%) cases were misclassified as high-grade mucoepidermoid carcinomas and one (5%) as squamous-cell carcinoma. The histologic evaluation in all cases showed cytomorphologic features resembling mammary duct carcinoma with marked cytonuclear atypia and occasional oncocytic appearance. Our cytohistologic correlations indicate that irregular clusters of high-grade adenocarcinoma cells with necrotic background and oncocytic features suggest a cytologic diagnosis of either primary salivary duct carcinoma or metastatic mammary carcinoma.

Abstract
BACKGROUND Automated image cytometry can allow concurrent quantification of several parameters in each individual cell within a population, opening new possibilities for diagnosis and prognosis. In this study, the authors investigated the capacity of this method for performing a bivariate analysis of DNA ploidy and synthesis in fine-needle samplings obtained without aspiration from breast tumors. METHODS Samplings from 25 unselected cases of ductal infiltrative breast adenocarcinoma and 2 cases of fibroadenoma were analyzed. For each case, 3-5 slides (containing approximately 1000 cells each) were quantified to assess experimental precision. Ploidy was determined by fluorescent staining of DNA using 4,6-diamidino-2-phenylindole (DAPI). Contaminating lymphocytes were taken as internal controls to calculate DNA indices. DNA synthesis was analyzed by immunofluorescent detection of 5-bromodeoxyuridine (BrdU) incorporation. Measurements were compared with flow cytometric data obtained from the same patients. RESULTS Relative error in determination of DNA indices was generally below 5%. Determination of proliferation indices were more variable, with a mean relative error of 25%. Two different populations of BrdU positive cells were detected systematically, one in the diploid and another in the aneuploid fraction. For both cytometric methods, DNA indices were similar in all 27 cases, whereas BrdU labeling indices showed no significant correlation in 13 cases. The remaining cases were not comparable due to lack of flow cytometric data. Labeling indices obtained by image cytometry did not reveal any significant correlation with Scarff-Bloom-Richardson grading or clinical staging. CONCLUSIONS Automated image cytometry allows concurrent measurement of ploidy and cell proliferation within individual breast carcinoma cells. Statistical reliability can be reached with a relative small number of cells (1000), which is crucial for samples in which the cell number is too low for flow cytometry analysis. Visual control for artifact elimination and better characterization of cell populations makes this a powerful tool for tumor cell investigation. Automated image cytometry allows the obtainment of valuable prognostic parameters of traditional flow cytometry with the relatively small number of cells obtained in aspiration procedures.

Abstract
Histologic findings from two consecutive series of fine-needle biopsies of nonpalpable breast lesions were compared. The first series included 243 tumors sampled stereotactically, and the second 198 tumors sampled under ultrasound guidance. The results, together with data from the literature, demonstrated that: 1) the diagnostic efficacy of stereotactic fine-needle cytology of lesions seen on mammograms only as microcalcifications is inadequate; 2) ultrasound-guided fine-needle cytology is an extremely reliable diagnostic tool for lesions that are not seen only as microcalcifications.

Abstract
We retrospectively compared fine-needle samplings (FNS) from two recently individualized low-grade papillary salivary carcinomas, polymorphous low-grade adenocarcinoma (PLGAC) and papillary cystadenocarcinoma (PCAC), to define the cytologic criteria allowing the correct diagnosis. Twelve PLGACs in 10 patients and 5 PCACs in 4 patients were investigated by FNS preoperatively. In both entities, smears contained variable proportions of malignant cells, occasionally arranged in pseudopapillary formations. In contrast to PCAC, PLGAC showed stromal fragments and hyaline globules resembling pleomorphic adenoma or adenoid cystic carcinoma. Cytologic diagnoses of malignancy were established in 10 (83.3%) PLGACs and in 4 (80%) PCACs. Two (16.7%) PLGACs were misdiagnosed as pleomorphic adenoma, and 1 (20%) PCAC as a salivary cyst.

Abstract
Fine-needle biopsy under ultrasound guidance is widely used in the diagnosis of subclinical breast lesions seen on mammograms. This minimally invasive procedure requires little time and is reliable for the diagnosis of lesions in a central or peripheral (axillary extension, upper part of the superomedial quadrant, mammary fold) location, or in small-sized breasts. The procedure is done in real time, allowing reliable verification of the specimen. The cytologic results are available almost immediately. Close collaboration between the radiologist and pathologist is essential.

Abstract
BACKGROUND In contrast to most major salivary gland malignancies, mucoepidermoid carcinoma has been rarely documented and tentatively accepted as carcinoma ex pleomorphic adenoma. The authors present the cytologic and clinical findings for six examples of these rare tumors. METHODS The six examples were identified during an extensive review of the authors' salivary gland files, and all were high grade mucoepidermoid carcinomas on histologic evaluation. RESULTS Overall, mucoepidermoid carcinomas cytologically presented as non-specific high grade malignancies and consisted of highly malignant cells, in clusters or isolated, that were rarely associated with intracellular and extracellular mucin. In only two cases, a background of cellular and stromal elements consistent with pleomorphic adenoma was identified. CONCLUSIONS Although it is nearly impossible cytologically to distinguish these lesions from other high grade primary or metastatic carcinomas (such as poorly differentiated squamous cell carcinomas, adenosquamous carcinomas, and salivary duct carcinomas), this limitation is not dramatic, as a cytologic diagnosis of high grade malignancy per se allows for proper preoperative patient management.

Abstract
Fine-needle samples of 75 non-Hodgkin's lymphomas were investigated for apoptosis immediately and after 24 h of culture after in vitro irradiation (2 Gy, 10 Gy, and nonirradiated controls). Apoptotic cells were simultaneously quantified by fluorescence microscopic enumeration of apoptotic cells using Hoechst 33342 staining, and by flow cytometric detection of sub-G1 peak cells. The nonirradiated controls showed a similar mean percent apoptotic cells using both methods, analyzed immediately (9% by morphology vs. 10% by flow) or after 24 h of culture (40% by morphology vs. 41% by flow). In the irradiated samples, the mean percent apoptotic cells quantified by morphology was higher than by flow cytometry (64% by morphology vs. 55% by flow after 2 Gy irradiation, and 71% vs. 58% after 10 Gy). The results of the two methods were correlated, although large differences were seen between the techniques in individual tumors. In our system, flow cytometric sub-G1 peak analysis appears to underestimate apoptosis. Of these two methods, we find the Hoechst morphology method to be more reliable for quantitation of apoptosis utilizing fresh fine-needle sample material, in that discrimination of apoptotic cells from debris is easier and that both early and late apoptotic cells are detectable.

Abstract
BACKGROUND The early diagnosis of nonpalpable breast lesions is a medical challenge because of the low specificity of different radiologic modalities. Fine-needle aspiration cytology (FNAC) assisted by a stereotactic guidance is an adjunctive diagnostic approach in the management of these lesions. The primary purpose of this article was to assess the diagnostic accuracy of FNAC in patients with nonpalpable breast lesions. METHODS Three hundred and seventy-one lesions from 357 patients (all female) underwent FNAC using the stereotactically guided technique. Of these cases, 243 lesions from 238 patients subsequently were acquired by surgical excisional biopsies and formed the basis of this study. Statistical analyses of the cytologic and the histologic diagnoses of these cases were performed. RESULTS Histologically, 107 lesions (44%) were benign and 136 lesions (56%) were malignant. Of the 136 malignant lesions, cytology was concordant in 73 lesions (53.7%), suspicious in 15 lesions (11.0%), false-negative in 12 lesions (8.8%) (benign), and unsatisfactory in 36 lesions (26.5%). Among the 107 benign lesions, cytology was concordant with histology in 75 lesions (70.1%), whereas 4 lesions (3.7%) and 28 lesions (26.2%) were cytologically suspicious and unsatisfactory, respectively. No false-positive cytologies were found in the current series. CONCLUSIONS The current prospective study indicates that mammography combined with FNAC provides an accurate and practical diagnostic approach for the majority of nonpalpable lesions. Patients with unsatisfactory and false-negative lesions should undergo excisional biopsy.

Abstract
BACKGROUND The value of ultrasound-guided fine-needle aspiration cytology (FNAC) in the diagnosis of nonpalpable breast lesions remains a subject of debate. To determine the accuracy of this procedure in these lesions, a comparative analysis with open surgical biopsy in 188 patients was performed. METHODS Six hundred and fifty-four nonpalpable breast lesions detected by ultrasound in 585 patients were subjected to FNAC. Of these, 198 lesions (30.3%) from 188 patients were surgically excised. RESULTS Histologically, 105 lesions (53%) were malignant and 93 (47%) were benign. Among carcinomas, 65 cases (61.9%) were concordant, whereas 21 cases (20%) were suspicious, 12 cases (11.4%) were false-negative (benign), and 7 cases (6.7%) were unsatisfactory for diagnosis. Among benign lesions, 80 cases (86%) were concordant, whereas 5 cases (5.4%) were suspicious, and 8 cases (8.6%) were unsatisfactory. No false-positive diagnoses were made. The sensitivity of the FNAC method was 87.8%, the specificity was 94.5%, and the positive predictive value was 94.6%. CONCLUSIONS These results indicate that, with the exception of random microcalcified lesions, ultrasound-guided FNAC is a valuable and reliable technique in the diagnosis of nonpalpable breast lesions.

Abstract
PURPOSE Prospective investigation of spontaneous and in vitro radiation-induced apoptosis to predict early response to palliative radiotherapy in patients with non-Hodgkin's lymphomas. PATIENTS AND METHODS Fine-needle sampling was performed in 28 tumor sites (26 patients) and yielded adequate cell numbers in 27 cases. Apoptotic cells were counted by fluorescence microscopy immediately after sampling and after 24-h culture (spontaneous apoptosis) and 24 h after 2- and 10-Gy in vitro irradiation (radiation-induced apoptosis). Early response to low-dose in vivo radiotherapy (mostly 4 Gy in two fractions over 3 days) was evaluated 15 days after treatment. RESULTS The tumor response rates at 15 days were 11 (39%) complete responses, nine (32%) responses of greater than 50% reduction in volume, six (21%) responses of less than 50% reduction in volume and two (7%) cases of no response. Tumors achieving complete or major response after in vivo irradiation had higher percentages of apoptotic cells after in vitro irradiation, while no significant differences in terms of spontaneous apoptosis were observed between responders and non-responders. CONCLUSION Spontaneous and in vitro radiation-induced apoptosis can be easily and quickly assessed on cells obtained by fine-needle sampling of non-Hodgkin's lymphoma lesions. The present results suggest that in vitro radiation-induced apoptosis could be used as a predictive assay of early response to low-dose in vivo irradiation in patients with non-Hodgkin's lymphomas.

Abstract
We investigated the interrelationship between p53 gene alterations, MDR1 gene expression, and S-phase fraction (SPF) in breast carcinomas treated primarily with chemotherapy or radiotherapy and correlated the results with patient outcome to determine the potential clinical significance of these factors. In a consecutive series of 64 fine-needle samplings of breast cancer patients who underwent either neoadjuvant chemotherapy (n = 53) or radiotherapy (n = 11), p53 (exons 5-9) gene alterations by denaturating gradient gel electrophoresis and subsequent direct sequencing, MDR1 gene expression by semiquantitative reverse transcription-PCR, and SPF by DNA flow cytometry were determined. Our results show that p53 mutations (n = 20) were significantly associated (P = 0.01) with high SPF but not with de novo MDR1 gene expression. Most patients with wild-type p53 tumors were found to be resistant to neoadjuvant chemotherapy. No correlation was observed between p53 mutations and the induction of MDR1 gene expression during treatment. Although a significant correlation between shorter distant disease-free survival and high (>/=5%) SPF (P = 0.016) was found, no correlation between distant disease-free survival and p53 status or intrinsic MDR1 gene expression was found. Poor overall survival was observed in patients with tumors with high SPF (P < 0.0004) or lacking MDR1 gene expression (P = 0.03) before treatment, but not with p53 alterations. These data suggest that SPF remains the most relevant biological factor for breast cancer patients treated by primary chemotherapy or radiotherapy and that p53 and MDR1 status may identify a small subset of patients that may resist therapy or pursue an aggressive course.

Abstract
Fine-needle sampling (FNS) of 22 acinic cell carcinomas, including 17 primary tumors, 4 local recurrences, and 1 lymph node metastasis was performed preoperatively in 17 patients. Cytologic diagnoses were concordant with histology in 3 (13.7%) cases, whereas 15 (68.2%) cases were cytologically classified as malignant, 2 (9.1%) as suspicious, and 1 (4.5%) as benign (pleomorphic adenoma). The material was unsatisfactory for cytologic evaluation in 1 (4.5%) case. Preoperative FNS technique is, therefore, useful in acinic cell carcinoma with a concordant malignant/suspicious rate of 91%.

Abstract
BACKGROUND It has been suggested that metastasizing pleomorphic adenomas may represent unrecognized malignancy. METHODS The cytologic and clinical characteristics of two metastasizing pleomorphic adenomas diagnosed by fine-needle sampling are reported. RESULTS Both showed malignant evolution: the primary tumors arose from the palate and the parotid salivary glands, respectively. Metastases occurred simultaneously with local recurrence in the first patient and after a second local recurrence in the second patient. Both patients were treated by surgery and radiotherapy but died of disseminated disease 8 and 4 years after initial diagnosis. No histologic evidence of malignancy was observed on cytology smears or histology sections in either case. CONCLUSION Clinically, our cases support the hypothesis that metastasizing pleomorphic adenomas represent unrecognized malignancy, because the biologic course of two tumors led to unequivocally lethal outcome.

Abstract
Fine-needle sampling (FNS) of 50 mucoepidermoid carcinomas, including 44 primary tumors, five local recurrences, and one lymph node metastasis, was performed preoperatively in 44 patients. Concordant cytologic diagnoses were established in only 19 (38%) tumors, whereas 15 (30%) were classified as carcinoma, five (10%) as suspicious, and six (12%) as benign tumors. The material was insufficient for cytologic evaluatin in five (10%) cases. The tumors were classified histologically as high-, intermediate-, and low-grade in 15, 13, and 22 cases, respectively. The quality of diagnosis did not vary between high- and intermediate-grade, but was lower in low-grade tumors: Malignancy was diagnosed or suspected in 13 (87%) high-grade tumors, 11 (85%) intermediate-grade tumors, and 15 (68%) low-grade tumors. In conclusion, FNS is an accurate technique in high- or intermediate-grade mucoepidermoid carcinomas, but quite unsatisfactory in low-grade tumors.

Abstract
Fine-needle sampling (FNS) of 75 adenoid cystic carcinomas, including 44 primary tumors, 18 local recurrences, 10 lymph node, and 3 distant metastases, was performed in 66 patients. Concordant cytologic diagnoses were established in 68 tumors (90.7%), whereas 4 (5.4%) were classified as malignant (adenocarcinoma), 1 (1.3%) as suspicious, and 1 (1.3%) as pleomorphic adenoma. The material was insufficient for cytologic evaluation in 1 (1.3%) tumor. Adenoid cystic carcinoma is, in our opinion, easy to diagnose using the FNS technique.

Abstract
DNA quantitation using fluorescent dyes is of interest in image cytometry in that it is nondestructive in its mode of staining and is compatible with techniques such as FISH and immunofluorescence, allowing multicolor analysis of a wide range of cellular markers of interest. Optimal preparation techniques were sought using human peripheral blood lymphocytes and fine needle samples of breast carcinomas. Unfixed (air-dried only), ethanol, ethanol/acetic acid, and paraformaldehyde/ethanol fixations were tested. Unfixed or fixed cells were placed on slides as a drop or by cytocentrifugation, stained with 4',6-diamidino-2-phenylindole dihydrochloride and DNA content was measured using image analysis. Histogram quality was evaluated using G0G1 peak coefficient of variation, and compared to those generated by flow cytometry. Drop preparations of ethanol/acetic acid fixed and cytospin preparations of paraformaldehyde/ethanol fixed cells appeared to give the best histograms for image analysis, which were inferior in quality to those generated by flow cytometry. Comparison of breast carcinoma histograms generated by flow and image showed the same DNA aneuploid populations but with slightly higher DNA indices measured by image analysis.

Abstract
Fine-needle sampling (FNS) of 71 Warthin's tumors was performed preoperatively in 70 patients. Cytologic diagnoses were concordant with histology in 50 (70.4%) tumors, whereas 14 (19.7%) cases were cytologically misclassified as benign lesions. Material for cytologic evaluation was unsatisfactory in seven (9.9%) cases, and no suspicious or false-positive diagnoses were observed. FNS is therefore a reliable preoperative technique for assessment of Warthin's tumor with a concordant/benign diagnostic rate of 90.1%.
