Abstract
PURPOSE Adenoid cystic carcinoma (ACC) is an uncommon salivary gland cancer with no approved therapies available to treat advanced, incurable disease. Recent molecular profiling efforts have identified two important subtypes: the more aggressive ACC-I is characterized by Notch pathway alterations and MYC amplification whereas ACC-II demonstrates a more indolent phenotype and TP63 overexpression. EXPERIMENTAL DESIGN This retrospective observational cohort study involved de-identified samples from 438 patients with ACC with tumor samples sent for commercially-available molecular profiling (Caris Life Sciences). Next-generation whole-exome and whole-transcriptomic sequencing was performed on primary and metastatic samples. Immunostaining for PD-L1 and RNA deconvolution (quanTIseq) was used to explore the tumor immune microenvironment (TME). Real-world clinical and survival outcome metrics were extracted from insurance claims data. RESULTS MYC expression was 1.61-fold higher (39.8 vs. 24.7; P < 0.0001) among NOTCH1-mutant ACC-I tumors, whereas MYB/L1 fusion rates were similar among ACC-I/II. The median B-cell fraction in the TME was higher among ACC-II (7.1% vs. 5.8%; P < 0.01), although infiltrating T cells subsets were low among either ACC subgroup (both <1%). When pooling systemic treatment categories, ACC-I patients had worse outcomes with available therapies (HR, 3.06; 95% confidence interval, 1.65-5.68; P < 0.01), with no significant difference in overall survival between ACC-I/II based on chemotherapy or VEGFR tyrosine kinase inhibitor exposure in smaller subsets. CONCLUSIONS We confirmed the previously reported associations with MYC and TP63 in the prognostically relevant subgroups of ACC-I and -II, respectively, and report immunologic differences among these subtypes. Survival outcomes are comparatively worse in ACC-I regardless of treatment type.

Abstract
OBJECTIVES Non-Hodgkin's lymphoma (NHL) risk assessment is crucial in Sjögren's syndrome (SS). We studied the prevalence of clonal immunoglobulin gene rearrangements in minor salivary glands (MSG) and their correlations with lymphoma occurrence and with previously established NHL predictors. METHODS Molecular B-cell expansion was studied in fresh-frozen MSG of 207 patients with either suspected SS or with suspected lymphoma during SS, using a standardised multiplex PCR assay combined with heteroduplex analysis by microcapillary electrophoresis. The assignation of clonal cases was based on EuroClonality consortium guidelines. RESULTS Among 207 studied patients, 31 (15%) had MSG monoclonal B-cell infiltration. Monoclonality was significantly more frequent in patients with SS (28/123, 22.8%) compared with patients without SS (3/84, 3.6%, P<0.001). Monoclonal B-cell infiltration in MSG of SS patients correlated significantly with ongoing salivary gland NHL, salivary gland swelling, CD4+ T-cell lymphopenia, rheumatoid factor (RF) activity, low complement levels and type 2 mixed cryoglobulinemia. The accumulation of biological risk factors was associated with a higher rate of MSG B-cell monoclonality given that patients with only positive RF had no probability of MSG B-cell monoclonality, RF-positive patients with 1 or 2 other risk factors had a 25.0% and 85.7% probability of MSG B-cell monoclonality, respectively. CONCLUSION The detection of MSG monoclonal B-cell expansion by this easy-to-perform molecular assay is useful, both at the time of diagnosis and during the course of SS. Monoclonal B-cell expansion is associated with a subset of SS patients presenting either ongoing lymphoma or other established lymphoma predictive factors.

Abstract
Warthin tumour (WT) is a benign tumour of the salivary gland that proliferates in both glandular epithelial and lymphoid tissue components, and rarely exhibits cystic changes. T follicular helper cells (Tfh) are involved in the formation and maintenance of germinal centres, the differentiation of B cells into plasma cells, and the maintenance of helper T cell type 2 (Th2)-dominant humoral immune responses. T-bet induces differentiation into helper T cell type 1 (Th1) by suppressing differentiation into Tfh and enhances cellular immune responses. The objective of this study was to enhance our understanding of the immune responses and relationship between Tfh and Th1 cells in patients with WTs. In this study, we classified WTs (n = 64) into solid-type (n = 25) and cyst-type (n = 39). We also performed immunostaining of the Tfh markers CXCR5 and CD40 L, and the Th1 marker T-bet for statistical analysis. The cyst-type exhibited significant atrophy of the germinal centre area (P = 0.0019), significantly fewer Tfh-positive lymphocytes in germinal centres (P < 0.0001), and significantly more T-bet-positive lymphocytes in the epithelium (P = 0.0017). We observed that Tfh were involved in the formation and maintenance of lymphoid follicles in WTs. In the cyst-type, Th2-dominant humoral immune responses were suppressed, and Th1-dominant cellular immune responses may have caused damage to tumour tissue.

Abstract
Salivary duct carcinoma (SDC) commonly expresses androgen receptor (AR) and HER2, giving rise to treatment implications. SDC may also express programmed-death-ligand-1 (PD-L1), a predictive marker of response to checkpoint inhibitors. PD-L1 can be associated with genomic instability and high density of tumor infiltrating lymphocytes (TILs). Evaluation of HER2 immunohistochemistry (IHC) in SDC is not standardized, and relationships between ERBB2 copy numbers, PD-L1 expression and TILs in SDC are unknown. We evaluated 32 SDCs for HER2, AR and PD-L1 expression (IHC), ERBB2 status (FISH) and TILs (slide review). HER2 was scored with three different systems (breast, gastric, proposed salivary gland). PD-L1 was evaluated with the combined positive score. Most patients were older men, presenting at advanced clinical stage with nodal or distant metastases. During follow-up (mean 5 years, range 6 months to 21 years), 25 of the 32 patients (78%) died of SDC. We propose a HER2 IHC scoring system which accurately predicts underlying ERBB2 amplification or increased copy numbers in SDC. Most tumors had increased ERBB2 copy numbers (19/32 amplification, 6/32 aneusomy), a finding associated with higher TIL densities (p = 0.045) and PD-L1 expression (p = 0.025). Patients with TILs ≥ 40% had better prognoses (Log-Rank p = 0.013), with TILs being favorable prognosticators in univariate analysis (Hazard ratio: 0.18, p = 0.024). A subset of SDCs with increased ERBB2 copy numbers have higher TILs and PD-L1 expression. TILs ≥ 40% are associated with better prognosis.

Abstract
The survival rate for head and neck cancer patients has not substantially changed in the last two decades. We previously showed that two rV-neuT intratumoral injections induced an efficient antitumor response and rejection of transplanted Neu (rat ErbB2/neu oncogene-encoded protein)-overexpressing salivary gland tumor cells in BALB-neuT mice (BALB/c mice transgenic for the rat ErbB2/neu oncogene). However, reiterated poxviral vaccinations increase neutralizing antibodies to viral proteins in humans that prevent immune response against the recombinant antigen expressed by the virus. Curcumin (CUR) is a polyphenol with antineoplastic and immunomodulatory properties. The aim of this study was to employ CUR administration to boost the anti-Neu immune response and anticancer activity induced by one rV-neuT intratumoral vaccination in BALB-neuT mice. Here, we demonstrated that the combined rV-neuT+CUR treatment was more effective at reducing tumor growth and increasing mouse survival, anti-Neu humoral response, and IFN-γ/IL-2 T-cell release in vitro than the individual treatment. rV-neuT+CUR-treated mice showed an increased infiltration of CD4+/CD8+ T lymphocytes within the tumor as compared to those that received the individual treatment. Overall, CUR enhanced the antitumoral effect and immune response to Neu induced by the rV-neuT vaccine in mice. Thus, the combined treatment might represent a successful strategy to target ErbB2/Neu-overexpressing tumors.

Abstract
OBJECTIVES To investigate if indicators of a heavier involvement of mucosa-associated lymphoid tissue (MALT) in primary Sjögren's syndrome (pSS), i.e. persistent salivary gland (SG) swelling and cryoglobulinaemia, might better evaluate the lymphoma risk compared to the ESSDAI. Therefore, the current concept of disease activity of pSS should be re-evaluated, based solely on ESSDAI. METHODS A cohort of 255 pSS patients, including 30 pSS with B-cell lymphoma, was investigated. Three subgroups were distinguished, i.e. pSS developing lymphoma in the follow-up (n=12), pSS with lymphoma at cohort inclusion (n=18), and control pSS not developing lymphoma in the follow-up (n=225). SG swelling, cryoglobulinaemia and ESSDAI were evaluated at baseline, in the follow-up to one year before lymphoma diagnosis, and at lymphoma diagnosis. RESULTS SG swelling and/or cryoglobulinaemia at baseline were significantly higher (p=0.0003) in pSS patients evolving into lymphoma if compared to pSS controls, while ESSDAI showed no significant difference. Both SG swelling and cryoglobulinaemia persisted and sometimes developed ex novo in the follow-up. SG swelling and cryoglobulinaemia were present in 24/30 (80%) cases the time of lymphoma diagnosis, and lymphoma itself was usually of MALT/marginal zone histotype (90%), leading to peculiar manifestation of lymphoma in pSS. CONCLUSIONS The autoimmune and lymphoproliferative involvement of MALT is the biological substrate of pSS. If this involvement is heavier, as reflected by SG swelling and cryoglobulinaemia, disease activity may be considered higher, and the risk of lymphoma is increased. The current concept and evaluation of activity of pSS, based solely on the ESSDAI, needs revision.

Abstract
OBJECTIVES ACA-positive/primary Sjögren's syndrome (pSS) represents a distinct overlapping entity with intermediate features in between limited systemic sclerosis (lSSc) and pSS. Few data are available on their general risk for lymphoproliferative complications, specifically regarding adverse predictors at the level of minor salivary gland (MSG) histology. The objectives of this work are: a) to characterise, through a detailed immunohistochemistry study, the organisation of the lymphomonocitic infiltrates in ACA-positive/pSS patient vs. ACA-negative/pSS patients focusing on the presence of GC-like structures in minor salivary gland biopsies; b) to compare the frequency of traditional clinical and serological risk factors for lymphoma between the two subgroups. METHODS We analysed 28 MSG samples from ACA-positive/pSS patients and 43 consecutive MSGs from ACA-negative/pSS, using sequential IHC staining for CD3, CD20 and CD21 in order to define the T/B cell segregation within the periductal infiltrates and presence of ectopic GC-like on the detection of GC-like structures. Clinical and serological data of all the patients were retrieved and analysed. RESULTS Ectopic lymphoid structures (ELS) with GC-like structures were observed in 7 out of 28 ACA-positive/pSS patients (25%) and in 13 out of 43 ACA-negative/pSS patients (30.2%). Similarly, no statistical significant difference was found between the two groups as far as the classical pSS risk factors for lymphoproliferative complications was concerned (i.e. salivary gland enlargement, purpura, low C4, leukocytopenia, clonal gammopathy). Finally, the 3 cases of non-Hodgkin's lymphoma observed were equally distributed between the two subsets. CONCLUSIONS Overall, this study indicates that ACA-positive/and ACA-negative pSS patients apparently present a similar risk for lymphoproliferative complications as suggested indirectly by the analogies between the two groups observed at the histopathology level.

Abstract
A cell line was established from a transplantable adenocarcinoma, containing viral particles of the A and B type, derived from a tumor appearing spontaneously in the submaxillary region of a male mouse of the C3H/He strain. This line, after 480 days in vitro, did not change the original epithelial-like morphology, the viral expression, the membrane immunofluorescence and the degree of agglutination by various plant lectins. After 208 days of culture, the presence of up to 3 pairs of metacentric chromosomes appeared in about 55% of the cells. However, this change in the chromosomal pattern was not sufficient, at least within the limits of our observation, to modify significantly the other parameters investigated, with the possible exception of the oncogenicity, which showed a modest decrease after 296 days of culture.

Abstract
Mammary analogue secretory carcinoma (MASC) of salivary glands is a newly recognized tumor entity. To explore a more practical and convenient immunohistochemical approach to distinguish MASC from other tumors arising from salivary glands as well as to expand the immunologic and genetic lineage of MASC, we examined 17 MASCs using clinicopathologic, immunohistochemical, and molecular analyses. Eighteen cases of acinic cell carcinoma, 18 cases of adenoid cystic carcinoma, 22 cases of mucoepidermoid carcinoma, and 14 cases of basal cell adenocarcinoma were brought in for comparison. Seventeen MASCs shared similar architectures with not only intraluminal or intracellular secretion but also low-grade vesicular nuclei. In addition, they were all immunoreactive for S-100 and SOX-10, whereas only 3 of 17 demonstrated reactivity for GATA-3 and P63, and 4 of 17 were focally positive for CD117. ETV6 translocation was detected in 10 cases by fluorescence in situ hybridization, whereas intact ETV6 was noted in 2 cases. Our data proposed a combined immunohistochemical panel to distinguish MASC from other tumors arising from salivary glands and expanded the immunologic and genetic lineage of MASC.

Abstract
PURPOSE The purpose of this study was to examine whether cytomegalovirus (CMV) is present in different histological types of salivary gland cancer (SGC) by detecting CMV immediate-early (IE) and early gene products, and to determine the presence of its association with the overexpression of interleukin (IL)-6. METHODS Immunohistochemical analysis of 92 cases of different histological types of SGC was performed to determine the presence of IL-6 and CMV antigen and its intensity in tumor tissue. Twenty samples of normal salivary gland tissue obtained during autopsy served as healthy controls. RESULTS CMV antigens were not found in healthy acinar tissue of salivary glands, but were expressed in epithelium of salivary gland ducts. Negative expression of CMV antigens was also found in salivary gland tissue surrounding tumors. On the other hand, CMV was detected in 65/92 SGC cases (70.6%). Higher expression of IL-6 was found in SGC (70.7%) than in normal tissue (20%). There was a high association of CMV antigen presence with the presence of IL-6, and with the IL-6 expression intensity. CONCLUSIONS Positive expression of CMV antigens in a high percentage of SGC cells suggests that it might play an important role in carcinogenesis by increasing IL-6 production and leading to inhibition of apoptosis and tumor development.

Abstract
BACKGROUND Salivary gland tumors are among malignancies that have high recurrence rate. Immune responses in salivary gland tumors have not been well elucidated. T helper type 1 (Th1) and Th2 cytokines have been reported to play a role in the outcome of head and neck cancers. OBJECTIVE To evaluate the serum levels of interferon gamma (IFN-γ), as the hallmark of Th1 cytokines, and interleukin-4 (IL-4), as the hallmark of Th2 cytokines, in patients with benign and malignant salivary gland tumors in comparison with healthy controls. METHODS Fifty patients with benign and 14 patients with malignant salivary gland tumors, as well as 23 healthy individuals were recruited. Serum levels of IFN-γ and IL-4 were measured using ELISA method. Nonparametric tests were used for data analysis. RESULTS Serum levels of IFN-γ and IL-4 were found not to be significantly different in patients compared to the control group (0.68±0.29 vs. 1.03±0.57pg/ml, p=0.58 for IFN-γ, 4.57±1.57vs. 4.41±1.31pg/ml, p=0.28 for IL-4). IFN-γ and IL-4 serum levels were also not significantly different between patients with benign and malignant salivary gland tumors (p=0.54 and p=0.86, respectively). CONCLUSION The systemic levels of IL-4 and IFN-γ seem not to be associated with salivary gland tumor in our study. Investigation of other cytokines produced by Th1 and Th2 cells are warranted.

Abstract
Myoepithelial cells play a central role in glandular tumors, regulating the progression of in situ to invasive neoplasias, with the tumor microenvironment being shown to be involved in both initiation and progression. This study aimed to analyze the in vitro effects of fibroblast growth factor-2 (FGF-2) and hepatocyte growth factor (HGF) in myoepithelial cells under the influence of the fibronectin matrix extracellular protein. Benign myoepithelial cells were obtained from pleomorphic adenoma and cultured on a fibronectin substratum. FGF-2 and HGF were supplemented at different concentrations and time intervals, in order to evaluate cell proliferation, morphology and immunophenotype. Individually, FGF-2 and HGF supplementation did not alter myoepithelial cell proliferation, morphology or immunophenotype. The fibronectin substratum provoked an increase in cell proliferation and immunopositivity for α-smooth muscle actin and FGF-2. The myoepithelial cell morphology changed when the fibronectin substratum and FGF-2 acted together, highlighting the importance of the fibronectin extracellular matrix protein on the behavior of these cells.

Abstract
Polymorphous low-grade adenocarcinoma (PLGA) originating mostly in the minor salivary glands of the posterior hard and soft palate is characterised by its indolent growth and a slower rate of metastasis. Seldom does the PLGA present an aggressive behaviour and demonstrate distant metastasis, as in the present case where a 73-year-old female patient with a swelling in the maxillary alveolus was diagnosed as PLGA exhibiting high-grade transformation, subsequently metastasizing to the abdomen and lungs. The importance of immunomarkers, c-kit and ki-67 in deciphering the clinical behaviour of this PLGA is highlighted. Distant metastasis to the abdomen has not yet been reported; hence, this case of PLGA emphasises the importance of immunohistochemistry in assessing its aggressiveness and understanding a novel aspect of its pathogenesis.

Abstract
In carcinoma ex pleomorphic adenoma (CXPA), pleomorphic adenoma (PA) and diverse carcinoma components showing luminal (ductal) or non-luminal (myoepithelial) differentiation coexist. To elucidate the clinicopathological implications of cellular differentiation in CXPA and the potential role of p53, vascular endothelial growth factor (VEGF), c-erbB-2, c-kit, and glucose transporter 1 (Glut-1) in carcinogenesis, we analyzed 11 CXPAs with luminal differentiation (CXPAs-LD) and 6 CXPAs with non-luminal differentiation (CXPAs-NLD) and compared protein expressions in residual PAs and carcinomas by immunohistochemistry. Among the CXPAs-LD, 5 were invasive and 8 were histologically high-grade tumors. The 5-year survival rate was 72.7%. P53, c-erbB-2, VEGF, and Glut-1 were more immunoreactive in carcinoma components than in PAs (P = 0.008, 0.004, 0.002, and 0.024, respectively); c-erbB-2 overexpression was associated with high histological grade (P = 0.024). Carcinoma components frequently lacked c-kit expression (P = 0.009). CXPAs-NLD were all low-grade and invasive with a larger mean tumor size (5.2 cm) than CXPAs-LD (3.3 cm) (P = 0.040). The patients remained disease-free without significant immunohistochemical expression. The immunoprofiles and clinical course of CXPA differed according to cellular differentiation. Therefore, it is important to report the histological subtype and to assess potential biomarkers in diagnostic and therapeutic trials.

Abstract
NK and γδ T cells can eliminate tumor cells in many experimental models, but their effect on the development of tumors caused by virus infections in vivo is not known. Polyomavirus (PyV) induces tumors in neonatally infected mice of susceptible strains and in adult mice with certain immune deficiencies, and CD8+ αβ T cells are regarded as the main effectors in anti-tumor immunity. Here we report that adult TCRβ knockout (KO) mice that lack αβ but have γδ T cells remain tumor-free after PyV infection, whereas TCRβ×δ KO mice that lack all T cells develop tumors. In addition, E26 mice, which lack NK and T cells, develop the tumors earlier than TCRβ×δ KO mice. These observations implicate γδ T and NK cells in the resistance to PyV-induced tumors. Cell lines established from PyV-induced tumors activate NK and γδ T cells both in culture and in vivo and express Rae-1, an NKG2D ligand. Moreover, these PyV tumor cells are killed by NK cells in vitro, and this cytotoxicity is prevented by treatment with NKG2D-blocking antibodies. Our findings demonstrate a protective role for NK and γδ T cells against naturally occurring virus-induced tumors and suggest the involvement of NKG2D-mediated mechanisms. Virus-induced tumors account for a large fraction of malignancies in both humans and mice. These tumors express viral antigens and have been thought to be controlled mostly by αβ TCR+ CD8 T lymphocytes that are specific for viral peptides. We found that mice lacking αβ T cells are protected from the formation of tumors induced by the small DNA virus polyoma (PyV) if they have γδ T and NK cells. Moreover, cell lines we established from the virus-induced tumors induced NK and γδ T cell activation, and expressed Rae-1, a cellular stress molecule which serves as ligand for NKG2D, an activating receptor on NK and γδ T cells. NK and γδ T cells seemed to mount antitumor but not antiviral responses, as their presence did not change the amount of persisting virus significantly. Our studies suggest that mice have a multipronged host defense against PyV-induced tumors that includes γδ T and NK cells in addition to αβ T cell responses. Merkel cell virus, a tumor causing polyomavirus in humans, is closely related to PyV with a similar biology, making it very important to understand mechanisms involved in host control of tumor development in the course of these life-long persistent infections.

Abstract
Individuals with acquired immunodeficiency syndrome (AIDS) manifest an increased risk of cancer, particularly cancers caused by oncogenic viruses. Because some salivary gland and nasopharyngeal cancers are associated with Epstein Barr virus, the impact of AIDS on these cancers needs further evaluation. We used linked U.S. AIDS and cancer registry data (N = 519,934 people with AIDS) to derive standardized incidence ratios (SIRs) comparing risk of salivary gland and nasopharyngeal cancers to the general population. For salivary gland cancers (N = 43 cases), individuals with AIDS had strongly elevated risks for lymphoepithelial carcinoma (SIR 39, 95% CI 16-81) and squamous cell carcinoma (SIR 4.9, 95% CI 2.5-8.6). Among nasopharyngeal cancers (N = 39 cases), risks were elevated for both keratinizing and nonkeratinizing carcinomas (SIR 2.4, 95% CI 1.5-3.7 and SIR 2.4, 95% CI 1.2-4.4, respectively). The elevated risks of salivary gland and nasopharyngeal cancers among people with AIDS suggest that immunosuppression and oncogenic viral infections are etiologically important.

Abstract
Warthin tumor was first described in the American literature, by Aldred Warthin, in 1929, the pathologist who named this tumor papillary cystadenoma lymphomatosum, but since than it was also knew as adenolymphoma, cystadenolymphoma, and Warthin tumor. Because of its microscopically appearance and unknown origin, this tumor entity is still fascinating head and neck surgeons and pathologist. We evaluate the histopathological aspect of Warthin tumors using Hematoxylin-Eosin stain, and immunohistochemical and histological techniques. We reviewed the medical record of patients with salivary gland tumors diagnosed at County Hospital of Timisoara from 2002-2008. In six years, 22 cases with Warthin tumor were diagnosed and among them 17 men and five women, with average age 58.47. The analysis showed that 77.27% of Warthin tumors occurred in men, and the main histopathological aspect was with 50% epithelial component. The stromal component showed a prominent B-cell population by staining with CD20, and histological techniques for mucin were positive, and reticulin fibers were revealed while using Gordon-Sweets stain. The standard and the histological and immunohistochemical techniques highlighted the complex and variable microscopical appearance of Warthin tumor that the pathologist should consider when a diagnosis for this tumor is to be considered.

Abstract
We proceeded with intratumoral injection therapy of dendritic cells (DC) in combination with hyperthermia for 41 cancer patients in the past two years. We confirmed a total of two CR cases (one of them already reported). We report two successful cases in this paper. Case 1: A uterine cervical cancer patient with metastases in cervical and abdominal lymphnodes was treated with intratumoral DC injection therapy combined with hyperthermia in cervical. She showed a CR not only in cervical but also in abdominal lymph nodes. Case 2: A sialyl grand cancer patient with metastases in cervical and axillary lymphnodes was treated with intratumoral DC injection therapy combined with hyperthermia in cervical. She showed a PR.

Abstract
Primary giant-cell tumor of the salivary gland is a rare lesion with an incompletely characterized histogenesis. To the best of our knowledge, only 16 cases have been previously documented in the English-language literature. We report a new case, which occurred in a 75-year-old man who presented with a parotid mass and cervical lymphadenopathy. The patient underwent a left total parotidectomy and cervical lymph node dissection. As far as we know, ours is the only reported case of a primary giant-cell tumor of the salivary gland in which the patient presented with lymph node metastasis. Because so little is known about giant-cell tumor of the salivary gland, we use the occasion of this case report to describe the cytologic, histologic, and immunohistochemical characteristics that we observed.

Abstract
CONCLUSIONS In computer-assisted analysis of acinic cell cancer (ACC) morphological characteristics of CD34 immunoreactivity were detected. Bigger vessel size, vessel irregularity, and lower intensity of CD34-positive vessel staining may indicate unfavorable prognosis. OBJECTIVES Salivary gland cancer (SGC) is a morphologically diverse group of malignancies, the most common histological types being mucoepidermoid, adenoid cystic and ACC, which has the most favorable prognosis of the three. The aim of this research was to study the applicability of automated image analysis as prognostic criteria in ACC. PATIENTS AND METHODS In a nationwide study covering SGC patients in Finland during 1991-1996, 34 patients with ACC (15 males, 19 females, aged 19-95 years, mean 55 years) were included. Parameters were measured from CD34-stained samples. RESULTS In all, 10 385 vessels were measured, of which 9873 were from specimens from patients who were alive 5 years after treatment (n=32, group I) and 512 were from patients who died of disease (n=2, group II). The following results were found in group II versus group I: mean vessel size 469 microm vs 272 microm (p=0.024); vessel irregularity 28.3 microm vs 22.3 microm (p<0.001); CD34 staining intensity 0.555 microm vs 0.584 microm (p=0.024).

Abstract
The proliferative activity of the tumor cells and the expression of tumor-associated genes and sex steroid hormone receptors were investigated immunohistochemically in ten cases of carcinoma ex pleomorphic adenoma (Ca-ex-PA) of the salivary glands. These were analyzed in benign and malignant components separately, and then were compared with ten cases of the other malignant tumors [adenocarcinomas, not otherwise specified (ACN) and salivary duct carcinomas (SDC)] and ten cases of pleomorphic adenomas (PA). The results obtained in this study were as follows: (1) malignant component of Ca-ex-PA showed a higher incidence of PCNA and Ki67 than benign component of Ca-ex-PA. A significant difference between benign component of Ca-ex-PA and PA was not observed. (2) A significant difference in the incidence of p53, c-erbB-2, EGFR overexpression was observed only between malignant component of Ca-ex-PA and benign component of Ca-ex-PA. (3) The incidence of PCNA, Ki67, p53, c-erbB-2 overexpression in malignant component of Ca-ex-PA showed the highest data among the four groups. These results suggest that Ca-ex-PA acquired the particular biological behavior in contrast to the other salivary neoplasms in the long-standing process while PA undergoes malignant transformation.

Abstract
UNLABELLED We aimed to increase the efficiency of adenoviral vectors by limiting adenoviral spread from the target site and reducing unwanted host immune responses to the vector. We complexed adenoviral vectors with DDAB-DOPE liposomes to form adenovirus-liposomal (AL) complexes. AL complexes were delivered by intratumoral injection in an immunocompetent subcutaneous rat tumor model and the immunogenicity of the AL complexes and the expression efficiency in the tumor and other organs was examined. Animals treated with the AL complexes had significantly lower levels of beta-galactosidase expression in systemic tissues compared to animals treated with the naked adenovirus (NA) (P<0.05). The tumor to non-tumor ratio of beta-galactosidase marker expression was significantly higher for the AL complex treated animals. NA induced significantly higher titers of adenoviral-specific antibodies compared to the AL complexes (P<0.05). The AL complexes provided protection (immunoshielding) to the adenovirus from neutralizing antibody. Forty-seven percent more beta-galactosidase expression was detected following intratumoral injection with AL complexes compared to the NA in animals pre-immunized with adenovirus. CONCLUSIONS Complexing of adenovirus with liposomes provides a simple method to enhance tumor localization of the vector, decrease the immunogenicity of adenovirus, and provide protection of the virus from pre-existing neutralizing antibodies.

Abstract
Salivary duct carcinoma (SDC) is an uncommon malignant tumor, characterized by aggressive behavior and poor prognosis. SDC usually arises from ductal epithelium of the major salivary glands, and it is quite infrequent elsewhere. We present a rare case of a 73-year-old man with SDC, which is possibly originated from the paranasal sinuses or the lacrimal system. Microscopic evaluation revealed that the tumor cells, with pleomorphic nuclei and abundant eosinophilic cytoplasm, formed cell nests and duct-like structure. A cribriform growth pattern was also seen. Immunohistochemical staining was positive for cytokeratins (CAM 5.2 and 34betaE12), gross cystic disease fluid protein 15 (GCDFP-15), and androgen receptor protein, while p63 and involucrin were negative. The patient already had multiple metastasis of the tumor in the lung at diagnosis, and he could not undergo definitive surgical procedures, because of severe restrictive lung disease. Although SDC in the sinonasal tract is quite rare, SDC should be in the differential diagnosis in these regions, due to its aggressive behavior and poor prognosis.

Abstract
OBJECTIVES In the present study, we attempted to identify cyclooxygenase-2 (COX-2) expression and Ki-67 index in carcinoma ex-pleomorphic adenoma (Ca ex-PA) using quantitative immunohistochemical analysis and to compare the benign component of the neoplasia. We also aimed to relate the overexpression of COX-2 with the pathways of malignant transformation of Ca ex-PA as evidenced by distinct morphological features. MATERIALS AND METHODS Forty Ca ex-PA from patients treated at Department of Otolaryngology, Yokohama City University Medical Center, Yokohama, Japan, from 1999 to 2005, were selected. All Ca ex-PA showed only one malignant histological component: adenocarcinoma (23 cases), adenoid-cystic carcinoma (10), epithelial-myoepithelial carcinoma (7). The tissues were stained with monoclonal antibodies to COX-2 and Ki-67. The results were analyzed using quantitative immunohistochemical analysis. We also analyzed the association of the histological classification of the carcinomatous component. RESULTS In the immunohistochemical analysis of COX-2 and Ki-67 index, significant increase was observed in Ca ex-PA, especially with adenocarcinoma, compared to pleomorphic adenoma and sialadenitis. Quantitative assessment is more sensitive as a measure of cellular protein content as compared to standard optical density measurement. CONCLUSIONS The data support the hypothesis that increased COX-2 expression is associated with early events in malignant transformation of pleomorphic adenoma.

Abstract
Mucosa-associated lymphoid tissue (MALT) lymphoma presentation in the oral cavity is very rare. Reported herein is a case of intraoral MALT lymphoma of the minor salivary gland in a 70-year-old woman with Sjogren's syndrome. Unexpectedly, a spontaneous clinically and histologically confirmed regression occurred 1 month after the tumor biopsy for diagnosis. Considering that salivary MALT lymphoma is associated with Sjogren's syndrome and that the chronic inflammation caused by Sjogren's syndrome persisted, it is hypothesized that the tumor clone might be present in the regressed lesion. Minimal residual tumor clone identical with the primary lesion was detected using the polymerase chain reaction (PCR) clonality assay for immunoglobulin heavy chain gene (IgH) rearrangement. No recurrence was clinically evident 38 months after the diagnosis. Spontaneous regression of MALT lymphoma should be examined at the molecular level in addition to clinical and histological evaluations. When minimal residual disease is detected, close follow up is necessary for early detection of the tumor relapse.

Abstract
In four patients with chronic sclerosing sialadenitis, serum immunoglobulin G4 concentration was markedly increased and abundant infiltration of immunoglobulin G4-positive plasma cells was observed in the salivary glands. Autoimmune pancreatitis occurred in the two patients during follow up. Chronic sclerosing sialadenitis and autoimmune pancreatitis would appear to show essentially the same pathophysiological mechanism. Measurement of serum immunoglobulin G4 concentration is useful in differentiating chronic sclerosing sialadenitis from neoplasia.

Abstract
Neural cell adhesion molecule (NCAM) is a type of cell surface glycoprotein and a member of the immunoglobulin superfamily. It has been reported that NCAM may be associated with perineural invasion by malignant salivary gland tumors such as adenoid cystic carcinoma. We have previously demonstrated that NCAM is constitutively expressed in the human salivary gland tumor cell line HSG, in vitro. In the present study, we have aimed to clarify the hypothesis that NCAM-mediated inhibition of salivary gland tumor proliferation is caused by homophilic binding and involves the prevention of signal transduction for perineural invasion using HSG cells. NCAM mRNA and protein expression was found to decrease in a dose-dependent manner upon treatment with the anti-NCAM antibody (MAb NCAM) for 24 h. The MTT assay showed a significant reduction in the number of viable HSG cells. Confocal laser microscopy showed that HSG cells underwent apoptosis after treatment with MAb NCAM. The activation of caspases 3, 7 and 9 was observed in HSG cells after treatment with MAb NCAM, thus confirming that apoptosis was induced by the activated caspases. Apaf-1 activity was also detected in HSG cells in a dose-dependent manner after treatment with MAb NCAM. The up-regulation of TGF-beta1-mediated NCAM expression appeared to lead to the activation of homophilic NCAM binding, further accelerating HSG cell proliferation. In addition, the localization of NCAM in adenoid cystic carcinomas (ACCs) was examined using an immunohistochemical method. NCAM was slightly to moderately positive in 9 of 13 cases (69.2%) of ACC. These findings suggest that NCAM is associated not only with a cell-to-cell adhesion mechanism, but also with tumorigenesis, including growth, development and perineural invasion in human salivary gland tumors.

Abstract
Several proliferation markers, such as DNA ploidy, Ki67, MiB1 and proliferating cell nuclear antigen have been shown to correlate with clinical course and prognosis in several epithelial tumours and lymphomas. In the present study, the prognostic relevance of these markers was evaluated in major salivary gland carcinomas. A sample of 36 cases out of 85 patients submitted to surgery for major salivary gland carcinomas at our institution between 1987 and 1997 were studied. The sample comprised 8 adenoid-cystic carcinomas, 6 ductal carcinomas, 11 mucoepidermoid carcinomas and 11 acinic cell carcinomas. Follow-up ranged from 1 to 12 years (mean 6.2). In some patients, DNA ploidy (euploid or aneuploid) was studied by flow cytometry. In others, proliferation activity was studied by means of monoclonal antibody MiB1, identifying cells in the proliferative cycle. In some patients, both techniques were used. Follow-up was related to these indices, TNM and stage. Even if ploidy suggested a favourable outcome in diploid cancer (13 favourable vs. 2 unfavourable) and poor outcome in aneuploid cancer (4 favourable vs. 5 unfavourable), the difference was not statistically significant with p = 0.06 in Fisher's exact test. Instead, the proliferative tumour cell fraction, evaluated by MiB1, was statistically correlated with prognosis. Comparing survival curves by Log rank Test it yielded p = 0.007 using an MiB1 cut-off of 5. Applying a cut-off of 20 yielded p = 0.001. Of particular interest were MiB1 values in acinic cell carcinomas for which grading is challenging and lacks consensus. In our group of acinic cell carcinomas, survival correlated with values of MiB1 > or < 15 with p = 0.009 in Log rank test. In conclusion, despite a trend towards correlation between ploidy and prognosis, the present study yielded p = 0.06, whereas the proliferative fraction assessed by MiB1 was significantly correlated with outcomes. Indeed, "growth fraction" in acinic cell carcinomas may stratify different classes of risk.

Abstract
BACKGROUND Peptide sequence homology between the gene product of human MUC4 and rat sialomucin complex (SMC) has recently been reported. Each contains a mucin subunit with antiadhesive activity linked to the plasma membrane by means of a transmembrane subunit with two epidermal growth factor (EGF)-like domains that act as ligand for ErbB2. This study investigates MUC4 and ErbB2 receptor expression in major and minor salivary gland mucoepidermoid carcinoma and correlates patterns of expression with clinical outcomes. METHODS MUC4 antigens and ErbB2 receptor expression are localized by immunohistochemical studies that use archival formalin-fixed and paraffin-embedded tissue. Clinical outcomes are determined by retrospective chart review of all patients (n = 28) with available archived pathologic specimens at the University of Miami-affiliated hospitals treated between 1994 and 2000. RESULTS Median survival time was 24 months (range, 2-60 months) among the nine patients who died, whereas median follow-up time in the remaining 19 patients is 33.4 months (range, 4.7-73 months). A trend toward a reduction in MUC4 antigen expression in high-grade tumors (55% expression) compared with low-grade (91% expression) and intermediate-grade (100% expression) tumors is identified (chi square, p =.0975). Patients with tumors expressing MUC4 antigens are at reduced risk of death (hazard ratio [HR], 0.20; p =.0531). Adjustment for pathologic grade, T stage, and age results in a much higher risk of death for patients whose tumors do not express MUC4 antigens, although this does not meet statistical significance (HR, 26.6; p =.1). Analysis of recurrence adjusting for T stage reveals that patients whose tumors do not express MUC4 antigens are at increased risk of recurrence compared with patients whose tumor expresses MUC4 antigens (HR, 6.37; p =.03). ErbB2 receptor staining is noted in seven of 28 patients, with five of these seven showing 2+ and 3+ membrane-staining patterns. Adjustment for pathologic grade and age suggests that patients whose tumors express high levels of ErbB2 (2+, 3+) are at increased risk of death compared with patients with low or no expression of ErbB2 (HR, 2.29; p =.32). MUC4 antigen positivity is seen in two of the five cases with 2+ and 3+ staining for ErbB2. CONCLUSIONS.: These findings suggest MUC4 antigen positivity is associated with reduced risk of death and reduced risk of recurrence and may identify a subset of patients with more favorable prognosis. Although limited by small sample size, analysis reveals ErbB2 overexpression is not consistently associated with MUC4 antigen positivity and might be associated with increased risk of death.

Abstract
OBJECTIVE The aim of this study was to investigate the mechanism(MDR) of multidrug resistance(MDR) of mucoepidermoid carcinoma in salivary gland. METHODS 40 cases of mucoepidermoid carcinoma in salivary gland were examined the MDR gene product P-glycoprotein using a monoclonal antibody JSB-1. And 10 of them were also investigated by detecting the expression of GST-pi. All the cases had not been accepted any therapy before the samples were collected. RESULTS 1. Positive expression of JSB-1 was observed in 27 of the 40 specimens. The positive expression was related not only with clinical stage, but also with differentiation degree. 2. The GST-pi positive expression was found in 9 of 10 cases. There was no significant different between the positive expression of JSB-1 and GST-pi. CONCLUSION JSB-1 and GST-pi play an important role in MDR of mucoepidermoid carcinoma.

Abstract
The diagnosis of salivary gland myoepithelioma, an entity with heterogeneous cytomorphology and inconsistent immunophenotype, rests on conventional histology. However, the clinical course cannot be predicted reliably from cytomorphological and immunophenotypic analysis. The present study determined the immunophenotype of a representative series of 12 myoepitheliomas and 21 malignant myoepitheliomas. Among the seven markers tested, antibodies against cytokeratins 5/6, S-100 protein, and vimentin produced the most consistent reactivity profile. Comparative genomic hybridization (CGH) profiles of 12 myoepitheliomas showed chromosomal losses in three of 12 cases. In myoepithelial carcinomas, however, ten of 19 tissues investigated by CGH lacked detectable cytogenetic aberrations. In five cases, aberrations involved chromosome 8, in line with observations in salivary gland carcinomas of other differentiation. One case that was represented in three separately localized manifestations of the disease proved informative as to the relevance of gross aberration for tumour development, as these tumours differed in their CGH profiles. Staining for cytokeratins 5/6 is a useful addition to the established immunohistological marker panel in the work-up of myoepitheliomas, because of its reliable expression in most cases and because it may underline the epithelial nature of the lesion. CGH proved to be of limited value as a diagnostic adjunct; the presence of numerous gross cytogenetic aberrations should raise the suspicion of malignancy. The low frequency of aberrations detectable by CGH in overtly malignant myoepithelial neoplasms suggests that gross cytogenetic alterations were acquired in the course of tumour progression and points to the relevance of genetic changes not resolved by CGH.

Abstract
BACKGROUND OK-PSA, a lipoteichoic acid (LTA)-related molecule isolated from a streptococcal agent OK-432, enhances anti-tumor immunity as a potent inducer of Th1-type cytokines. Recently, we obtained the data suggesting that natural killer (NK) cells may play a significant role for OK-PSA-induced cytokine production in vitro. MATERIALS AND METHODS We conducted the animal experiments using athymic nude mice bearing human salivary adenocarcinoma to examine the role of NK cells in OK-PSA-induced anti-tumor immunity. OK-PSA was peritumorally injected into the mice. Cytokines in the sera were analyzed by ELISA. mRNAs for cytokines were detected by RT-PCR. 51Cr release test was performed to measure killer cell activities. RESULTS OK-PSA markedly increased the amounts of IFN-gamma, tumor necrosis factor (TNF)-alpha, interleukin (IL)-2, IL-12 and IL-18 that are generally called "Th1-type cytokines" in the sera derived from tumor-bearing nude mice, and also accelerated the killing activities of tumor-infiltrating lymphocytes as well as of draining lymph node cells. Furthermore, OK-PSA administration resulted in significant inhibition of tumor growth, but the effect of OK-PSA was almost completely inhibited by the deletion of NK cells using anti-asialo GM1 antibody. CONCLUSION These findings strongly suggested that NK cells are closely involved in OK-PSA-mediated anti-tumor immunity.

Abstract
We report the case of a patient with lymphoma of the salivary gland, at first diagnosed as lymphoma of mucosa-associated lymphoid tissue (MALT lymphoma) but later found to infiltrate the bone marrow. At diagnosis, the patient had a polyclonal increase of gamma-globulins. Five years after initial diagnosis, the patient presented with monoclonal gammopathy and infiltration of the bone marrow with neoplastic cells. Initially, the patient had received chemotherapy with different protocols (including etoposide, cyclophosphamide, fludarabin, methotrexate, and vincristine), none of which induced a lasting response. Therapy with rituximab (chimeric anti-CD20 monoclonal antibody) finally led to partial remission. Eighteen months after rituximab, progressive lymphoma in the abdomen and a monoclonal gammopathy developed. The bone marrow showed infiltration by lymphoplasmacytoid cells (monoclonal expression of the light-chain type lambda, positive for CD20, heterogeneous expression of CD45). The patient achieved another short clinical response with 4 cycles of the CHOP-protocol, but soon the lymphoma progressed again. Five years and 8 months after the initial diagnosis, the patient died from septicemia and progressive lymphoma. By polymerase chain reaction (PCR) for the IgH gene it was shown that lymphoma cells were initially oligoclonal in the salivary gland and, later, biclonal in the bone marrow. Sequencing of two bands of apparently same length showed that these manifestations of lymphoma were not identical. Taken together, our data show that the initial low-grade oligoclonal MALT lymphoma was no longer present and a more aggressive biclonal lymphoma with plasmacytoid differentiation had developed. The new lymphoma was clonally distinct and produced high amounts of monoclonal IgG lambda by immunoelectrophoresis. The relationship of the second lymphoma to the initial MALT lymphoma is discussed.

Abstract
To clarify the clinicopathologic, immunohistologic, and genotypic features of follicular lymphoma arising from the salivary glands, we examined 20 cases of operatively resected primary salivary gland lymphoma and identified 6 such cases. There were 4 women and 2 men with ages ranging from 38 to 64 years (median 50 years). The tumor arose from the parotid gland in 4 cases and the submandibular gland in the remaining 2. Four patients were stage IE and 2 were stage IIE-1. The median follow-up period was 49 months and all patients were alive and well at the time of going to press. Histologically, 5 patients were follicular lymphoma grade 2, and 1 was grade 3. In all specimens in noninfiltrating salivary gland tissue, there was periductal lymphocytic infiltration near the lymphoma. Moreover, myoepithelial sialoadenitis was noted in 2 lesions. An immunohistochemical study revealed all 6 cases were CD10+, CD79a+, bcl-6+, CD3-, CD5-, CD21-, CD23-, and CyclinD1-. The tumor cells expressed bcl-2 in 3 cases and p53 oncoprotein in 4 cases. Two cases revealed clonal bands with polymerase chain reaction (PCR) assay for the immunoglobulin heavy (IgH) gene. The bcl-2/IgH translocation at the major breakpoint region was detected in 1 case (16%). We found a relatively high incidence of follicular lymphomas (30%) in salivary gland lymphomas. Among the mucosa-associated lymphoid tissue (MALT) system, follicular lymphomas appeared to occur frequently in the salivary glands as well as the duodenum and skin. Moreover, follicular lymphoma arising from the salivary glands appeared to have some of the characteristics of MALT-type lymphoma including indolent prognosis, presence of myoepithelial sialoadenitis, and rarity of the BCL-2 gene rearrangement.

Abstract
OBJECTIVE To find whether there is any synergistic effect of radiation combined with interleukin-2(IL-2) activated tumor draining lymph nodes lymphocytes (DNL) from oral-carcinoma patients on high-lung metastatic salivary adenoid cystic carcinoma cell line(ACC-M). METHODS Colony-forming test was used to investigate antitumor effect and analyzed using linear-quadratic(LQ) equation and single hit multi targets equation. RESULTS The ratio of effect to targets was 25:1. The cytotoxicity of DNL was 49.06%. Radiation combined with DNL showed higher antitumor activity compared with radiation alone, alpha value, Dq and S2 were 0.7688 and 0.342 0; 1.5901 and 0.5995; 0.4481 and 0.1135 respectively(P < 0.05). CONCLUSIONS It indicates that in initial region of survival curve, DNL significantly increased sublethal damage on ACC-M.

Abstract
Salivary gland mucosa associated lymphoid tissue (MALT) type lymphomas are B-cell neoplasms that develop out of a reactive infiltrate, often associated with Sjögren's syndrome. Previous reports from our laboratory involving 10 patients suggested these lymphomas expressed a restricted immunoglobulin (Ig) V(H) gene repertoire with over use of V1-69 gene segments. To better determine the frequency of V1-69 use and whether there may also be selection for CDR3 structures, we sequenced the V(H) genes from 15 additional cases. Over half of the potentially functional V(H) genes (8 of 14) used a V(H)1 family V1-69 gene segment, whereas the other cases used different gene segments from the V(H)1 (V1-46), V(H)3 (V3-7, V3-11, V3-30.3, V3-30.5), and V(H)4 (V4-39) families. The 8 V1-69 V(H) genes used 5 different D segments in various reading frames, but all used a J4 joining segment. The V1-69 CDR3s showed remarkable similarities in lengths (12-14 amino acids) and stretches of 2 to 3 amino acids between the V-D and D-J junctions. They did not resemble CDR3s typical of V1-69 chronic lymphocytic leukemias. This study extends our earlier work in establishing that salivary gland MALT lymphomas represent a highly selected B-cell population. Frequent use of V1-69 appears to differ from MALT lymphomas that develop at other sites. The high degree of CDR3 similarity among the V1-69 cases suggests that different salivary gland lymphomas may bind similar, if not identical epitopes. Although the antigen specificities are presently unknown, similar characteristic CDR3 sequences are often seen with V1-69 encoded antibodies that have anti-IgG or rheumatoid factor activity.

Abstract
OBJECTIVE To investigate the possibility that various salivary gland tumors that look histologically similar could express p53 oncoprotein and Ki-67 proliferation antigen differentially and possibly aid in distinguishing benign from malignant lesions. STUDY DESIGN Intraoral paraffin-embedded biopsy specimens of salivary gland tumors were used. Thirty-eight pleomorphic adenomas, 17 adenoid cystic carcinomas, 23 monomorphic adenomas, and 17 polymorphous low-grade adenocarcinomas were stained with p53 and Ki-67 antibodies by using an immunoperoxidase detection system. Each case was evaluated in terms of staining intensity and percentage of cells staining. RESULTS Ki-67 and p53 antigens are expressed in generally low levels in the histologically well-differentiated salivary tumors that were studied here, both benign and malignant. Only 1 solid-type adenoid cystic carcinoma showed a high percentage of cells expressing p53. CONCLUSIONS The histologically well-differentiated salivary tumors studied do not show differential expression of p53 and Ki-67, in spite of their differing courses of biologic behavior. These antibodies should not be relied on to distinguish benign from malignant lesions of the salivary glands; however, they might be markers for those lesions that are dedifferentiating histologically and, therefore, might be displaying more aggressive behavior.

Abstract
Immunohistochemical detection of cell proliferation-associated antigens was investigated in 28 cases of adenoid cystic carcinoma (ACC) and 20 cases of pleomorphic adenoma (PA), using antibodies against DNA topoisomerase type II alpha (topo-II) (Ki-S1) and Ki-67 (MIB-1). The correlation of staining indices with clinicopathological data, histological features and prognosis was also studied. The topo-II value was significantly higher in ACC than in PA (P<0.0001), and highest in the solid growth pattern of ACC. In addition, significant relationships were found between topo-II values and clinical features such as local recurrence, surgical margins, and distant metastases. By log-rank test, the topo-II index was also correlated significantly with patient survival (P<0.01). The values of topo-II index paralleled those of Ki-67 index in ACC, and a correlation coefficient of 0.97 was obtained. Topo-II may be considered an additional marker for estimating the proliferating fraction of cells and for predicting the short-term prognosis for patients with salivary gland tumors.

Abstract
It has been reported that certain chemotherapeutic agents exhibit effects that enhance the antitumor host responses in the patients with malignant diseases. In the present study, we investigated whether cis-diamminedichloroplatinum (cisplatin) and 5-fluorouracil (5-FU) may induce cytokines and effector cells with antitumor efficacy in vivo and in vitro. The cultivation of human peripheral blood mononuclear cells (PBMC) in the presence of cisplatin (0-1.0 microg/ml) or 5-FU (0-5.0 microg/ml) resulted in the significant augmentation of natural killer (NK) and lymphokine-activated killer (LAK) cell activities as well as generation of interferon (IFN) gamma, tumor necrosis factor (TNF) alpha, beta interleukin(IL)-1beta, IL-6 and IL-12 in vitro. In addition, all of these activities were almost completely neutralized by addition of anti-asialoGM1 antibody and complement (P < 0.05). In an in vivo model, the administration of anti-asialoGM1 antibody significantly shortened the survival time extended by the treatment with cisplatin or 5-FU (P < 0.05), both on nude mice bearing salivary gland tumors and on syngeneic MethA-tumor-bearing BALB/c mice. Furthermore, high levels of NK and LAK activities and significant increases of the numbers of cells positive for asialoGM1, IFNgamma, TNFalpha, or IL-1beta were detected in the spleen cells derived from animals given cisplatin or 5-FU as compared with those given saline (P < 0.001-0.05). These findings clearly indicate that cisplatin and 5-FU are potent inducers of several types of cytokines and effector cells carrying antitumor activity mediated by asialoGM1-positive cells (mainly NK cells) for the most part, and that these abilities are closely associated with the in vivo antitumor effect of these agents.

Abstract
The monoclonal antibody 44-3A6 detects a cell-surface protein that has been shown to be a useful marker in distinguishing adenocarcinomas from other histologic tumor types in a variety of tissues. The objective of this study was to determine whether 44-3A6 could be used as a tool in the classification of salivary gland neoplasms. These complex tumors share overlapping pathologic features but distinct clinical outcomes. This study used 44-3A6 to immunohistochemically describe the pattern and frequency of this antigen in salivary gland neoplasms. Formalin-fixed, paraffin-embedded tissue sections of 22 benign and 26 malignant salivary tumors were evaluated. The patient population consisted of 25 (52.1%) women and 23 (47.9%) men selected from archival pathology files to reflect a range of salivary gland diseases. Normal surrounding salivary glands were found to have intense focal staining almost exclusively localized to ductal luminal cells. There was little staining of either myoepithelial or acinar cells. A wide spectrum of expression was found between and within tumor types, but a trend toward more expression of this antigen with decreasing differentiation was seen. A significant increase in staining was also seen in those tumors with ductal differentiation (n = 41) as opposed to those with predominantly acinar (i.e., acinic cell carcinoma) or myoepithelial (i.e., myoepithelioma; n = 8) differentiation (2.6 vs. 1.3, p < 0.05). No correlation was found between staining intensity and facial paralysis, pain, skin involvement, TNM stage, residual disease, or disease-free or total survival. Therefore this antigen appears to designate a duct luminal phenotype in normal and neoplastic salivary tissues.

Abstract
Helicobacter pylori is a common cause of chronic gastritis and has been implicated as the main agent responsible for the development of lymphomas of mucosa associated lymphoid tissue (MALT) in the stomach. An uncommon cause of salivary gland swelling is salivary lymphoepithelial lesion (SLEL), which shows histological features of acquired MALT and is associated with the development of MALT-type lymphomas. Since H. pylori has been identified in the oral cavity, we hypothesised that this organism might act as a potential antigen for the development of MALT in salivary glands. Routinely processed biopsies of 20 SLEL were screened for H. pylori DNA using a sensitive two-stage PCR technique to amplify the 16S ribosomal RNA gene. Immunoglobulin heavy chain gene monoclonality was determined by amplifying the VDJ gene using a nested PCR technique. All SLEL had histological features of organised MALT and 14 cases showed Ig heavy chain gene monoclonality consistent with MALT lymphoma. None of the SLEL contained H. pylori DNA. In contrast to the putative role of H. pylori as an antigenic stimulus in gastric MALT lymphomas, it appears not to play a role locally in the development of MALT or MALT lymphomas of the salivary gland.

Abstract
Primary extranodal malignant non-Hodgkin's lymphoma arising from the mucosa-associated lymphoid tissue (MALT-type lymphoma) represents a subtype of B-cell lymphoid malignancies with distinct clinicopathological features and is often associated with a favorable prognosis. Unlike the situation in nodal non-Hodgkin's lymphoma of B-cell lineage, few data are still available concerning the chromosomal constitution of MALT-type lymphomas. Until now, cytogenetic data from 29 low-grade MALT lymphomas with karyotypic alterations have been reported from different institutions, and virtually no data were available for high-grade MALT-type lymphomas. We have analyzed the cytogenetics of 44 MALT lymphomas arising in the stomach, parotid gland, thyroid gland, lung, breast, and conjunctiva. Clonal chromosome aberrations have been detected in 13 of 20 (65%) low-grade and 20 of 24 (83%) high-grade tumors. More than half of the low-grade lymphomas with abnormal karyotypes (7 of 13 cases, 53%) displayed clonal t(11;18)(q21;q21), thus specifically associating this translocation with MALT-type lymphomas for the first time in a larger series. In contrast, t(11;18) was not found in a single case of 20 high-grade MALT-type lymphomas with abnormal karyotypes, nor were translocations t(14;18) or t(3;14), characterizing about 10-35% of primary nodal large cell lymphomas. Instead, these lymphomas were associated with t(8;14)(q24;q32) in three cases, frequent deletions in the long arm of chromosome 6, and partial or whole gains of chromosomes 3, 7, 17, 18, and 21.

Abstract
The criteria for distinguishing benign lymphoepithelial lesions (BLEL) from low grade B-cell lymphomas of mucosa-associated lymphoid tissue (MALT) type in salivary glands and the significance of genotypically documented clonality in this setting are controversial. In addition, the clinical implications of a neoplastic diagnosis are unclear. The histopathologic features of 68 specimens from 49 patients with at least one salivary gland biopsy with LEL together with available clinical data were, therefore, reviewed. Paraffin section immunohistochemical (IHC) stains for kappa, lambda, CD3, CD20, and CD43; in situ hybridization (ISH) for kappa and lambda; and polymerase chain reaction (PCR) for immunoglobulin (Ig) HC rearrangement were performed. The 61 salivary gland specimens were classified as BLEL-13, BLEL with monocytoid B-cell (MBC) halos (BLEL-halo-8), low grade B-cell lymphoma of MALT type with confluent zones of MBC or other atypical lymphocytes (ML-MALT-24), low grade B-cell lymphoma of MALT type with monoclonal plasma cells (ML-MALT-PC-12), and high grade B-cell lymphoma of MALT type (MALT-high grade-4). Soft tissue and perineural invasion was not observed in BLEL and was most common in the MALT lymphomas. Lymph node involvement was identified in six patients at the time of their salivary gland MALT lymphomas but in none with BLEL. CD43+ B cells were seen most commonly in ML-MALT but were present in all other categories except MALT-high grade. Clonal B cells were identified by PCR in 5 of 12 BLEL, 5 of 8 BLEL-halo, 17 of 22 ML-MALT, 6 of 10 ML-MALT-PC, and 3 of 3 MALT-high grade biopsies. All ML-MALT-PC were clonal by ISH or IHC. Repeat biopsies in 14 patients most commonly showed a BLEL/ML-MALT lesion in an ipsilateral or contralateral salivary gland with one transformation to a MALT-high grade. Although only a few patients are known to have received chemoradiation or radiation therapy, most patients with low-grade lesions have pursued an indolent course. These data show the presence of two types of borderline lesions within the spectrum of lymphoid proliferations associated with salivary gland LEL. One has clonal B cells without histological features of neoplasia and the other nonconfluent MBC extending beyond the confines of LEL ("halos"). They share some features with the infrequent nonneoplastic BLEL and others with the more common low-grade B-cell lymphomas of MALT. A few high-grade B-cell lymphomas of MALT were also identified including a rare example of transformation from a low- to high-grade lesion. The optimal therapeutic approach for the borderline and low-grade lesions and the reason why so many of the lymphoproliferative lesions associated with LEL remain localized to the neck remain to be defined.

Abstract
The NOTCH4 gene, the human counterpart of the mouse mammary tumor gene, int-3, has been recently localized near the boundary of the HLA class II and class III regions. This gene is one of candidates for development of salivary gland tumor. Microsatellite polymorphism of (CTG)n repeat in the signal peptide domain of NOTCH4 was analyzed in Japanese including the patients with salivary gland tumor. Four alleles consisting of 6, 9, 10 and 11 repetitions of CTG (Leu) were observed and found to be in linkage disequilibria with HLA class I and class II alleles. No significant association of this microsatellite polymorphism with the disease were observed in 26 samples of salivary gland tumor. In this neoplasia, neither large-scale deletion nor translocation was detected around the NOTCH4 gene using genomic Southern hybridization analysis by the NOTCH4 cDNA as a probe.

Abstract
Salivary gland mucosa-associated lymphoid tissue (MALT) type lymphomas are typically indolent B-cell neoplasms that are often associated with Sjogren's syndrome. To better define the cell of origin and evaluate whether antigen receptor stimulation may be playing a role in tumor growth, the Ig heavy and light chain variable genes (VH and VL) expressed by five salivary gland MALT lymphomas were cloned and sequenced. Comparison to known germline sequences indicated that three of the lymphoma VH genes were derived from 51p1, a member of the VH1 family, while the other two used different VH gene segments from the VH3 family, 22-2B and HG19. All five of the VL genes belonged to the VkIII family, with three derived from Humkv325 and the other two from the Vg and Humkv328 genes. Numerous point mutations relative to the proposed germline genes were present in all of the lymphoma VH and VL genes. In addition, the VH and VL genes from each lymphoma showed intraclonal sequence heterogeneity indicative of ongoing somatic hypermutation. Because the process of Ig gene hypermutation is thought to occur at the germinal center stage of B-cell development, these findings suggest the MALT lymphoma cell of origin may be a germinal center B cell. Selection against mutations that result in replacement of amino acids suggested that Ig stimulation may be important for lymphoma growth. The possibility that antigen receptor stimulation may be involved in the growth of salivary gland MALT lymphomas is further suggested by the noted restricted use of VH and VL gene segments.

Abstract
OBJECTIVE This study investigates the distribution of the alpha chain of the integrin family of extracellular matrix receptors in a series of adenomas and carcinomas of salivary gland origin to determine if the malignant phenotype is associated with modification of the expression of these receptors. STUDY DESIGN Cryostat sections of 36 tumor specimens were stained by a standard streptavidin-biotin-peroxidase technique using primary monoclonal antibodies against alpha 1-6 and alpha v integrin chains. The immunohistochemical reaction was scored using a three-point scale and the results were analyzed using Fisher's exact test. RESULTS In salivary adenomas, alpha 2, alpha 3, alpha 4, alpha 6, and alpha v chains were widely expressed in most of the cases studied. The alpha 1 subunit was prominently expressed by the epithelial cells of Warthin's tumor, whereas a minority of pleomorphic adenomas showed immunoreactivity for this antigen. We observed alpha 5 subunit expression only in the mesenchymal-like component of pleomorphic adenomas. In salivary carcinomas, integrin alpha chain expression was heterogeneous, varying greatly between different histotypes and within the same histotype. The distribution of the antigens was similar to that of adenomas, except for the alpha 6 chain, which localized not only at the interface between cell and matrix, but also at sites of cell-cell contact. When the immunohistochemical levels of integrin alpha chain expression were compared in adenomas and carcinomas, expression significantly decreased for the alpha 6 and alpha v chains (p = 0.0007; p = 0.002, respectively). CONCLUSIONS Loss of alpha 6 and alpha v integrin subunits occurring in salivary gland carcinomas could modify the adhesive properties of malignant cells, contributing to the invasive potential of these tumors.
