Abstract
AIMS Low-grade myofibroblastic sarcoma (LGMS) is a rarely metastasizing myofibroblastic tumour mostly affecting extremities and the head and neck of adults. Histologically, it shows long infiltrative fascicles of spindle cells with moderate nuclear atypia. By immunohistochemistry, it stains positive for smooth muscle actin (SMA) and sometimes for desmin. To date, no recurrent genetic abnormalities have been described. Ubiquitin-specific peptidase 6 (USP6) gene rearrangement is typically found in some benign bone and soft-tissue tumours including nodular fasciitis (NF), among others. Nevertheless, rare cases of USP6-rearranged tumours resembling NF with atypical features have been reported. METHODS AND RESULTS One index case of LGMS of the deltoid in a 56-year-old man presented the THBS2::USP6 translocation by RNA sequencing (Archer FusionPlex Sarcoma v2 panel). Further screening of 11 cases of LGMS using fluorescent in situ hybridization (FISH) analysis with a USP6 break-apart probe identified two additional cases. These cases were investigated with RNA-sequencing, and a RRBP1::USP6 translocation was detected in one. The other case was not assessable because of low-quality RNA. Noteworthy, rearranged LGMSs presented distinctive features including variable multinodular/plexiform architecture, prominent vasculature with occasional wall thickening, scattered osteoclast-like multinucleated giant cells, and peripheral lymphoid aggregates. CONCLUSION Our findings support the notion that among soft-tissue neoplasms with fibroblastic/myofibroblastic phenotype, USP6 rearrangement is not limited to benign tumours, and warrants further investigation of genetic changes in myofibroblastic sarcomas.

Abstract
Nodular fasciitis (NF) is a benign myofibroblastic proliferation characterized by rapid growth, a self-limiting course, and USP6 gene rearrangement. Although it can arise in the head and neck region, very few cases of NF involving the sinonasal tract have been reported to date. Herein we report a case of NF involving the nasal cavity presenting as a polypoid well-defined mass causing obstructive symptoms in a male with a history of multiple local surgeries. Although the mass had an unusual clinical presentation, the histopathologic and immunohistochemical findings were consistent with NF. Fluorescent in situ hybridization performed with break-apart probes flanking the USP6 locus on chromosome 17p13 revealed the presence of USP6 gene rearrangement. The patient remained free of disease 124 months after surgical treatment. Considering its remarkably benign behavior despite its alarming clinical and histologic features, the distinction of NF from sinonasal malignant tumors is essential.

Abstract
Recurrent laryngeal carcinoma presents differences from the primary tumor that largely depend on the treatment. In this article, we review the histologic and molecular treatment-induced changes that may affect the diagnosis of recurrent laryngeal carcinoma, the assessment of predictive markers, and the response to treatment with immune checkpoint inhibitors. Radiotherapy induces profound modifications that are strictly related to necrosis of different tissue components, fibrosis, and damage of the tumor vessels. Postradiotherapy recurrent/persistent laryngeal squamous cell carcinoma typically presents a discohesive growth pattern within a fibrotic background associated with significant changes of the tumor immune microenvironment, with both important immunosuppressive and immunostimulatory effects. Overall, the increase of immunoregulatory cells and immune checkpoints such as CTLA-4, TIM-3, PD-1, and PD-L1 induced by radiotherapy and chemotherapy strongly supports the use of immune checkpoint inhibitors in recurrent/persistent laryngeal carcinoma. Future studies aiming to identify predictive factors of the response to immune checkpoint inhibitors should consider such treatment-induced modifications.

Abstract
BACKGROUND In mice models, eosinophils have been divided into different subpopulations with distinct phenotypes and functions, based on CD62L and CD101 patterns of membrane expression. Limited data are available in humans. OBJECTIVE To investigate eosinophils subpopulations in peripheral blood (PB) and nasal polyp tissue (NP) from severe eosinophilic asthma (SEA) patients plus concomitant chronic rhinosinusitis with nasal polyps (CRSwNP). METHODS We recruited 23 SEA patients (14 with CRSwNP); as controls, we enrolled 15 non-severe asthma patients, 15 allergic rhinitis patients without asthma and 15 healthy donors. Eosinophils were isolated from PB and NP and analysed by FACS. Eotaxin-3 and eotaxin-1 mRNA expression in NP tissue was also evaluated. RESULTS A significantly higher percentage of circulating CD62Llow cells was observed in SEA, as compared with controls, expressing higher levels of CCR3, CD69 and lower levels of CD125 (IL-5R), CRTH2, CD86 and CD28 in comparison with CD62Lbright cells. In NP, eosinophils showed a high proportion of CD62Llow phenotype, significantly greater than that observed in PB. Surface expression of IL-3R, IL-5R, CD69 and CD86 was significantly higher in CD62Llow eosinophils from NP than in those from blood. Moreover, eotaxin-3 mRNA expression positively correlated with the percentage of CD62Llow cells in NP. CONCLUSION Two different eosinophil subphenotypes can be identified in blood and NP of SEA patients, with a preferential accumulation of CD62Llow inflammatory cells in NP.

Abstract
MiR-34c targeting MUC2 is higher in ITACs compared to the corresponding normal mucosa. MiR-34c is higher in differentiated compared to mucinous ITACs. Low nasal washings miR-34c correlates with higher disease extension. Mir-34c targets critical targetable cancer and inflammatory related pathways. Mir-34c is a noninvasive candidate biomarker for ITAC patients and exposed workers.
Introduction Sinonasal intestinal-type adenocarcinomas (ITACs) are rare and aggressive tumors, closely related to professional exposure to wood dusts or leather. Here we explored the role of non-coding RNAs controlling MUC2 in liquid biopsies and tumors from ITAC patients with the aim of identifying biomarkers and molecular mechanisms to improve early diagnosis, prognosis, and therapeutic approaches for this rare cancer. Methods MiR-34c-3p, lncRNA AF147447 and MUC2 were measured in tumors and normal mucosa, in nasal washings (NW) from the affected and non-affected nostril and in plasma from 17 ITAC patients. The Apparent Diffusion Coefficient (ADC) was also evaluated by Magnetic Resonance Imaging. Results MiR-34c was higher in ITACs compared to the corresponding normal mucosa (p = 0.021). Differentiated tumors exhibited higher miR-34c levels (p = 0.025) and lower ADC values (p<0.001) compared to mucinous ones and these parameters were also inversely correlated (r = 0.87; p = 0.001). High MUC2 tumor expression was associated with orbital extension (p = 0.010). Low miR-34c levels in NW were associated with orbital (p = 0.009) and intracranial (p = 0.031) extension and with advanced TNM stage (p = 0.054). Functional analysis identified Wnt, Focal adhesion, MAPK and inflammatory signalings among the pathways most enriched in mir-34c targets. Discussion Our results suggest measuring miR-34c in NW as a biomarker for early diagnosis and monitoring of ITAC patients and for the surveillance of wood and leather exposed workers. Further research on the involvement of miR-34c regulated pathways in ITAC tumorigenesis may also allow the development of new therapeutic approaches for this rare cancer.

Abstract
Clinical responses to anticancer therapies in advanced soft tissue sarcoma (STS) are unluckily restricted to a small subgroup of patients. Much of the inter-individual variability in treatment efficacy is as result of polymorphisms in genes encoding proteins involved in drug pharmacokinetics and pharmacodynamics. The nucleotide excision repair (NER) system is the main defense mechanism for repairing DNA damage caused by carcinogens and chemotherapy drugs. Single nucleotide polymorphisms (SNPs) of NER pathway key genes, altering mRNA expression or protein activity, can be significantly associated with response to chemotherapy, toxicities, tumor relapse or risk of developing cancer. In the present study, in a cohort of STS patients, we performed DNA extraction and genotyping by SNP assay, RNA extraction and quantitative real-time reverse transcription PCR (qPCR), a molecular dynamics simulation in order to characterize the NER pathway in STS. We observed a severe deregulation of the NER pathway and we describe for the first time the effect of SNP rs1047768 in the ERCC5 structure, suggesting a role in modulating single-stranded DNA (ssDNA) binding. Our results evidenced, for the first time, the correlation between a specific genotype profile of ERCC genes and proficiency of the NER pathway in STS.

Abstract
Recurrent salivary gland carcinomas (RSCs) are poorly characterized and their clinical features and treatment options have not yet been fully described. The goal of this study was to analyze the therapeutic strategies and oncological outcomes of RSC patients through a literature review analysis. This systematic review was performed according to the PRISMA statements. Inclusion criteria for the systematic review were based on the population, intervention, comparison, and outcomes according to (PICO) framework. Two thousand seven hundred and four records were selected and 1817 recurrences were studied. Three hundred and sixty-five patients underwent salvage surgery (20.1%) and their 5-year mortality rate, overall survival and disease-free survival were 35%, 70%, and 42%, respectively. RSCs are aggressive neoplasms with a high rate of distant metastases (28.9%). Salvage surgery can be considered in patients with limited local and/or regional recurrences, even in case of single distant relapse, appearing within the first 3 years of follow-up.

Abstract
PURPOSE Authors retrospectively analyzed possible prognostic factors in a series of patients affected by Ewing sarcoma of extremities (eEWS) and treated over a 20-year period at a single institution. METHODS Between 1997 and 2017, 88 bone eEWS were treated at our institution. Staging, age, gender, tumoral volume, local treatment, surgical margins, post-ChT necrosis were investigated for prognostic correlation with overall survival (OS) and event-free survival (EFS). Median follow-up was 74 months (1-236). RESULTS Staging of disease correlated with OS (81% vs 59%, p = 0.01) and not with EFS (68% vs 57%, p = 0.28) in localized vs metastatic eEWS at presentation. Age ≥ 14 years (p = 0.002) and volume ≥ 100 cm3 (p = 0.04) were significant negative prognostic factors. No difference was found in local treatment: OS was 76% vs 63% (p = 0.33), while EFS was 68% vs 49% (p = 0.06) after surgery alone or surgery + radiotherapy, respectively. Regarding surgical margins, OS was 76% vs 38% (p = 0.14), and EFS was 65% vs 33% (p = 0.14) in adequate vs not adequate, respectively. OS was 86% and 68% in good and poor responders, respectively (p = 0.13). CONCLUSION In eEWS, metastatic disease at presentation, age > 14 years and tumoral volume > 100 cm3 are negative prognostic factors. Intensified adjuvant ChT can improve prognosis in poor responders and metastatic patients.

Abstract
AIMS Secretory carcinoma (SC) (synonym: mammary analogue secretory carcinoma) is a low-grade salivary gland tumour that occurs in both major and minor salivary glands. SC is known for its wide morphological, architectural and immunohistochemical spectrum, which overlaps with those of several salivary gland neoplasms, including acinic cell carcinoma (AciCC) and intercalated duct-type intraductal carcinoma (IDC) in major salivary glands, and polymorphous adenocarcinoma (PAC) in minor salivary glands. These tumours share with SC some morphological features and SOX10 immunoreactivity; also, with the exception of AciCC, they all coexpress S100 and mammaglobin. METHODS AND RESULTS We compared MUC4 and mammaglobin expression in 125 salivary gland carcinomas (54 genetically confirmed SCs, 20 AciCCs, 21 PACs, and 30 IDCs) to evaluate the potential of these two markers to differentiate these entities. Moderate to strong diffuse MUC4 positivity was detected in 49 SCs (90.7%), as compared with none of the IDCs and PACs. In contrast, mammaglobin was frequently expressed in SCs (30 of 36 cases; 83.3%), IDCs (24/28; 85.7%), and PACs (7/19; 36.8%). Two of three high-grade SCs lost MUC4 expression in the high-grade tumour component. No significant correlation was found between MUC4 expression and the fusion variant in SC (ETV6-NTRK versus non-ETV6-NTRK). CONCLUSION The results of our study identify MUC4 as a sensitive (90.7%) and specific (100%) marker for SC, with high positive (100%) and negative (93.4%) predictive values. Thus, MUC4 may be used as a surrogate for SC in limited biopsy material and in cases with equivocal morphology.

Abstract
Synovial sarcoma (SS) is a malignant mesenchymal soft tissue neoplasm. Despite its name, the cells of origin are not synovial cells, but rather neural, myogenic, or multipotent mesenchymal stem cells have been proposed as possible cells originators. Unlike other sarcomas, an unusual presentation of long-term pain at the tumor site has been documented, but the exact mechanisms have not been fully clarified yet. The transient receptor potential ankyrin 1 (TRPA1) is a nonselective cation channel mainly expressed in primary sensory neurons, where it functions as a pain sensor. TRPA1 have also been described in multiple non-excitable cells, including those derived from neural crest stem cells such as glial cells and, in particular, Schwann cell oligodendrocytes and astrocytes. We evaluated TRPA1 expression in SS. We selected a cohort of 41 SSs, and by immunohistochemistry, we studied TRPA1 expression. TRPA1 was found in 92.6% of cases. Triple TRPA1/pS100/SOX10 and TRPA1/SLUG/SNAIL staining strongly supports a neural origin of SS. TRPA1 positivity was also observed in a subset of cases negative with pS100, SOX10 and/or SLUG/SNAIL, and these divergent phenotypes may reflect a process of tumor plasticity and dedifferentiation of neural-derived SSs. Given the functional diversity of TRPA1 and its expression in neuronal and non-neuronal multipotent neural crest stem cells, it remains to be determined whether TRPA1 expression in SSs neoplastic cells plays a role in the molecular mechanism associated with premonitory pain symptoms and tumor progression.

Abstract
Sensor-based technological therapy devices could be a possible neurorehabilitation strategy for motor rehabilitation in patients with stroke during the post-acute hospitalization, especially for treating upper extremities function limitations. The audio-visual feedback devices are characterized by interactive therapy games that allow training the movement of shoulders, elbows, and wrist, measuring the strength and the active range of motion of upper limb, registering data in an electronic database to quantitatively monitoring measures and therapy progress. This study aimed to investigate the effects of sensor-based motor rehabilitation in add-on to the conventional neurorehabilitation for improving the upper limb functions in patients with subacute stroke. Thirty-seven patients were enrolled in the study and randomly assigned to the experimental group and the control group. The training consisting of twelve sessions of upper limb training compared with twelve sessions of upper limb sensory-motor training, without robotic support. Both rehabilitation programs were performed for 40 minutes three times a week, for 4 weeks, in addition to conventional therapy. All patients were evaluated at the baseline (T0) and after 4 weeks of training (T1). The within-subject analysis showed a statistically significant improvement in both groups in all clinical scales. The analysis of effectiveness revealed that, compared with baseline (T0), the improvement percentage in the Modified Barthel Index was greater in the experimental group than the control group. The use of a sensor-based training with audio-video-feedback could be a useful complementary strategy for improving upper limb motor functions in patients with stroke during post-acute neurorehabilitation.

Abstract
Immunotherapy is a new option for head and neck squamous cell carcinoma. Very limited data are available for concurrent radio-immunotherapy in recurrent disease. Our case report adds to this very limited series, focusing on oligopression under immunotherapy.
Immune checkpoint inhibitors (ICIs) represent a recently introduced class of agents active in head and neck squamous cell carcinoma (HNSCC). For a subgroup of patients with recurrent or metastatic disease, long-term benefit can be achieved: maintaining a sustained response to immunotherapy is therefore a critical factor for its efficacy at an individual level. In analogy to targeted agents, a limited pattern of progression, or “oligoprogression”, can occur. For locally recurrent HNSCC, the potential biologic interplay between the efficacy of ICIs and the design of radiation fields chosen for primary treatment is currently unknown. Here, we report on a patient who presented two subsequent oligoprogressions successfully treated with re-irradiation without interrupting Nivolumab. Both oligoprogressive lesions developed in previously unirradiated areas. We hypothesize the existence of a synergistic effect with optimal spatial cooperation between ICIs and re-irradiation for oligoprogressive disease under immunotherapy.

Abstract
INTRODUCTION This case-series is aimed to describe the natural history of epithelioid sarcoma (ES) and to provide insights into the differential clinical behaviour of its two variants ("classic-type" and "proximal-type"). The value of a subtype-adapted grading system based on pathological features is explored. METHODS Data from consecutive, primary, localised, INI1-deleted ES operated at three Italian sarcoma reference centres (1995-2015) were included. Centralised pathological review was performed. Classic-type ES was broken down into "high-grade" and "low-grade", according to number of mitoses, evidence of necrosis and nuclear atypia. Five- and 10-year overall survival (OS) and crude cumulative incidence (CCI) of local recurrence (LR) and distant metastasis (DM) were estimated. RESULTS Fifty-two patients were included. 5- and 10-year OS estimates were 70% and 47% in the whole series, 57% and 37% in patients with proximal-type ES, 77% and 54% in patients with classic-type ES (P = 0.02). In classic-type ES, 5- and 10-year OS was higher for low-grade (95% and 72%, respectively) than high-grade tumours (P = 0.002). 5- and 10-year CCI estimates for LR were 21% and 33% in the whole series. 5- and 10-year CCI estimates for DM were 35% and 39% in the whole series, both 28% in classic-type ES, 47% and 59% in proximal-type ES (P = 0.03). CONCLUSIONS Suffering from a proximal- or a classic-type is the stronger predictor of outcome in patients with localised ES, with proximal-type ES patients having lower survival due to a higher tendency toward metastatic spreading. However, the "high-grade" classic-type ES was associated with outcomes close to proximal-type ES.

Abstract
Negative symptoms account for a clinical dimension of schizophrenia. They are partly the cause of functional disability of this disease. Clinical experience shows that antipsychotics have little or no effect on these symptoms. The aim of this review is to gather existing data on the treatment of negative symptoms with antidepressants. The combination of antipsychotics with antidepressants is a therapeutic strategy commonly used for the treatment of these symptoms. The pro-dopaminergic effects of antidepressants explain their effectiveness on negative symptoms. There are many comparative, randomized, controlled studies evaluating the efficacy of antidepressant associated with antipsychotic for the treatment of negative symptoms. Furthermore three meta-analyses have been conducted. The overall results suggest that the use of antidepressants may contribute to clinical improvement of negative symptoms in schizophrenia. The limitations of these studies are the small number of patients included and the definition and assessment of negative symptoms. The existing scales are not sufficiently discriminating. Further research using new measurement tools should help refine these results.

Abstract
It has been hypothesized that the development of sinonasal intestinal-type adenocarcinoma (ITAC) occurs through intestinal metaplasia (IM) of the respiratory and/or glandular epithelium. The aim of this study was to characterize the histological, immunohistochemical, and molecular features of sinonasal IM. Histologic slides from 29 consecutive surgical specimens of ITAC were retrieved. Sections were stained for CDX2, cytokeratin 20 (CK20), MUC2, and p53. The status of TP53 gene exons 4-9 was assessed separately in areas of IM and in ITAC. Foci of IM were detected in eight cases (27.5%). They were all positive for CK20 and CDX2, while MUC2 was detected in six cases (75%). In six cases (75%), the metaplastic foci showed signs of dysplasia, including nuclear enlargement with increased nucleus to cytoplasm ratio, nuclear hyperchromasia, loss of nuclear polarity, and presence of prominent nucleoli. P53 nuclear immunoreactivity was observed in four cases. TP53 gene sequencing was successfully performed in six cases and revealed the same mutation in both IM and ITAC in two cases (c.832C > T and c.215G > C), while another ITAC showed a mutation that was not present in the adjacent IM (c.536A > G). In conclusion, our study suggests a possible clonal relationship between areas of sinonasal IM and ITAC, indicating that IM may represent a precursor lesion of ITAC. Improving the knowledge on the morphological and molecular features of IM is a key step to identify reliable biomarkers to determine the risk of sinonasal ITAC development.

Abstract
Neuroendocrine neoplasms represent a rare subset of tumors in the sinonasal tract. Combined tumors, with an endocrine and a non-neuroendocrine component, are exceedingly rare, and mainly consist of a combination of neuroendocrine carcinoma with adenocarcinomas. We present the clinico-pathologic and immunohistochemical features of a neuroendocrine carcinoma combined with squamous cell carcinoma, arising in the maxillary sinus. In addition, we evaluated the clonal origin of the two components through analysis of TP53 gene status. Both components were positive for cytokeratins AE1/AE3, while the squamous cell carcinoma was positive for cytokeratin 5/6 and p63, and the neuroendocrine carcinoma showed immunoreactivity for neuron specific enolase, chromogranin, synaptophysin and CD56. In situ hybridization for human papilloma virus and Epstein-Barr virus were negative in both components. A missense mutation in TP53 exon 7 (c.734G>C) and strong nuclear immunostaining for p53 were detected only in the neuroendocrine carcinoma. This suggests that the tumor either derived from one precursor cell with squamous differentiation, which underwent TP53 mutation and acquisition of a neuroendocrine phenotype, or it derived from two separate clones, one with mutated TP53 and neuroendocrine differentiation, and the other with wild type TP53 and squamous differentiation (collision tumor).

Abstract
We describe the clinicopathological, immunohistochemical, and molecular features of 3 primary juxtacortical myoepithelioma/mixed tumor of bone. The patients were 2 males (13 and 23 years of age) and a 15-year-old female. The juxtacortical lesions were all located in the femur, and were surgically removed, 2 with wide margins and one with marginal margins. This latter tumor recurred locally 18 months later. The 3 patients were free of disease at 6 to 17 months follow-up. Histologically, all lesions showed a prominent multinodular architecture, and were formed by epithelioid and stellate elements, organized in solid sheets, or embedded in myxoid or chondroid matrix. Areas of osteoid formation were also observed. One tumor had the appearance of classical mixed tumor, showing aspects of duct formation and focal squamous differentiation. Immunohistochemically, all cases were positive for cytokeratins, epithelial membrane antigen, and S100 protein. The expression of other myoepithelial markers, including p63, glial fibrillary acid protein and calponin was more limited. No rearrangement of Ewing sarcoma region 1 (EWSR1) and fused in sarcoma (FUS) genes was observed by fluorescent in situ hybridization. To our knowledge, this is the first report of primary myoepitheliomas of bone arising at juxtacortical sites. These lesions must be distinguished from other benign and malignant bone and cartilage-forming surface tumors, including periosteal chondroma and chondrosarcoma, juxtacortical chondromyxoid fibroma, and periosteal and paraosteal osteosarcoma. The clinicoradiologic presentation and their histological and immunohistochemical features are distinctive enough to allow the separation from these entities.

Abstract
AIMS Sinonasal intestinal-type adenocarcinoma (ITAC) is an uncommon neoplasm morphologically similar to colorectal adenocarcinoma, with a well-recognized association with occupational exposure to wood or leather dusts. Here, we analyse several gene products with pivotal roles in tumorigenesis, including p53, p16, deleted in colon cancer (DCC), retinoblastoma, adenomatous polyposis coli, β-catenin, E-cadherin and CD10, and discuss their relation to clinical behaviour and to similar pathways in colorectal adenocarcinomas. METHODS AND RESULTS Immunohistochemical analysis of 62 ITACs was conducted on a tissue microarray. Aberrant expression of p53 and p16 were the most commonly observed alterations (61.3% and 64.5% of cases, respectively). Analysis according to the histological subtype showed that p53 overexpression was less frequent in mucinous ITACs (35.3% versus 71.1%, P = 0.018), while loss of DCC and E-cadherin were observed more frequently in this subtype (76.5% versus 31.1%, P=0.002 and 82.4% versus 31.1%, P<0.001, respectively). No correlation was found between the aberrant expression of these and clinical behaviour while mucinous adenocarcinomas had a significantly worse prognosis, with shorter disease-free interval and overall survival (P=0.005 and P<0.001, respectively). CONCLUSIONS Mucinous ITACs appear to follow a distinct molecular pathway(s) from the non-mucinous variants, and pursue an aggressive clinical behaviour.

Abstract
Several malignant tumours occurring in the sinonasal tract may present with an undifferentiated morphology. Overall, these lesions pose significant diagnostic difficulties for the surgical pathologist, especially in limited biopsy material, but their correct classification is becoming increasingly important for an appropriate treatment strategy. This review deals with the criteria for differential diagnosis of these neoplasms, with emphasis on recent advances in immunohistochemistry and molecular biology, as well as with previous progress in electron microscopy. Through careful microscopic examination of haematoxylin and eosin-stained sections, in the light of clinical information and imaging data, a list of differential diagnoses can be made and an appropriate panel of antibodies can be chosen to further categorize the tumour. An initial panel including cytokeratins, synaptophysin, S100 protein, desmin and CD45 may allow the classification of most lesions or may help to narrow the list of differential diagnoses. Further refinement can be obtained through second-line markers, including in-situ hybridization for Epstein-Barr virus, other neuroendocrine markers, melanocytic markers, myogenin, CD99, other lymphocyte markers, and CD138 and light chains. Finally, molecular analysis can further assist in the recognition of specific entities such as nuclear protein in testis midline carcinoma, Ewing's sarcoma/peripheral neuroectodermal tumour, alveolar rhadbomyosarcoma, and poorly differentiated synovial sarcoma.

Abstract
Sinonasal carcinomas are rare tumors with an aggressive clinical behaviour which frequently pose a number of problems regarding the interpretation of diagnostic findings and the treatment. In addition, in comparison with other malignancies of the head and neck region, an elevated fraction of sinonasal carcinomas can be attributed to occupational exposure. This review is focused on the recent advances in the molecular and phenotypic characterization of sinonasal carcinomas, and their possible implications for the interpretation of epidemiological data, as well as for the diagnosis and treatment of these rare malignancies. The increasing knowledge on their phenotypic and genotypic features is progressively leading to a refinement in diagnosis, especially for poorly differentiated and undifferentiated lesions, as well as to the identification of markers which can be potentially useful to identify the early phases of carcinogenesis, to detect subclinical disease, to predict the response to therapy, and finally, that may represent potential targets for alternative treatments.

Abstract
BACKGROUND The association between intestinal-type sinonasal adenocarcinoma and the occupational exposure to leather dusts has been widely documented, but the identification of precursor lesions in exposed workers has remained controversial. The purpose of this study was to investigate the histological changes and modifications in the phenotype of epithelial cells in nasal mucosa of leather workers. METHODS Biopsy specimens of the mucosa of the middle turbinate were obtained from 139 subjects who had been employed in leather factories for 10-48 years (median, 29 years). Tissue fragments were routinely processed for histological examination and immunostainings for cytokeratin 20, CDX-2, and MUC-2 were performed. RESULTS Regarding the surface epithelium, the most common histopathological finding was the presence of squamous metaplasia (64.7%), which was associated with mild to moderate dysplasia in 37 cases (41.1%), and goblet cell hyperplasia was identified in 30 biopsy specimens (21.6%). Positivity for MUC-2 was detected in goblet cells of 20 of the 30 samples with goblet cell hyperplasia (66.6%), whereas no immunostaining was observed for cytokeratin 20 and CDX-2. Presence of goblet cell hyperplasia was significantly associated with longer occupational exposure in leather tanning activities (p = 0.03). None of the alterations observed (squamous metaplasia, dysplasia, or goblet cell hyperplasia) showed correlation with smoking habits. Similarly, there was no correlation between squamous metaplasia with or without dysplasia and type and duration of occupational exposure. CONCLUSION Our data identify goblet cell hyperplasia as possible work-related alterations of nasal mucosa in leather workers. Additional investigations are needed to clarify the significance of these findings in the development of sinonasal intestinal-type carcinoma.

Abstract
Because the histopathological features of some primary adenocarcinomas of the sinonasal tract may show considerable overlap, we assessed the diagnostic value of a panel of immunohistochemical markers in the distinction between these malignancies. Paraffin-embedded tumour tissue sections from a series of 39 primary adenocarcinomas of the sinonasal tract, including 25 cases of intestinal-type adenocarcinoma (ITAC), 10 cases of salivary gland-type carcinoma and 4 cases of tubulopapillary low-grade adenocarcinoma were immunostained for CDX-2, cytokeratin 7 and cytokeratin 20. Diffuse nuclear staining for CDX-2 was identified in 80% of ITACs, while all non-ITACs were negative. Staining for cytokeratin 20 was positive in 84% of ITACs, including all cases negative for CDX-2, but negative in all other adenocarcinomas. Cytokeratin 7 was consistently positive in 88% of ITACs and in 100% of non-ITACs. Normal sinonasal epithelia expressed cytokeratin 7, but not CDX-2 and cytokeratin 20. Staining for CDX-2 and cytokeratin 20 has potential use in separating ITACs from other primary malignant glandular neoplasms of the nasal cavities and paranasal sinuses.

Abstract
Imatinib mesylate (IM), is a selective and competitive inhibitor of tyrosine kinases, including BCR-ABL, ABL, KIT, and the platelet-derived growth factor receptors (PDGF-R). It binds to the ATP-binding site of the target kinase and prevents the transfer of phosphate from ATP to the tyrosine residues of various substrates. At oral doses of 200-600 mg, the majority of patients with chronic myeloid leukaemia, Philadelphia chromosome-positive acute lymphoblastic leukemia expressing the BCR-ABL fusion protein and gastrointestinal stromal tumours (GIST) achieve a bio-molecular and clinical response, frequently complete, associated with limited toxicity. Several other human cancers, as small-cell lung carcinoma, melanoma, seminoma, some sarcomas, and adenoid cystic carcinomas may over-express KIT or PDGF-R, and clinical trials to evaluate the role of IM in the treatment of such cancers are currently ongoing. We determined c-KIT with Dako CD 117 antibody in 5 cases of advanced ocular melanoma (OM) and we found positive immuno-reactivity for CD 117 in three patients. We treated all patients with palliative-use IM at the oral dose of 400 mgr daily. We obtained in expressing positive immuno-reactivity for CD 117 patients: a reduction of malignant ascites in one, a partial remission in the neck nodes in another, and progression of liver metastases in the third. Evidences of progression has been reported in the other two patients expressing negative immuno-reactivity for CD 117. We conclude that the effect of IM should be assessed only in OM with positive immuno-histochemical c-kit (CD 117) expression. IM might be a potential therapeutic strategy for these patients.

Abstract
Lymph node involvement is the most important prognostic factor for patients who have undergone radical surgery for colorectal carcinoma. An accurate examination of the surgical specimens is mandatory for the correct assessment of the lymph node status of the tumor. The risk of understaging is particularly high for patients with tumors classified as Dukes B (TNM stage II). The aim of this study was to determine if a specified minimum number of lymph nodes examined per surgical specimen could have any effect on the prognosis of patients who had undergone radical surgery for Dukes B colorectal cancer. Between 1988 and 1995 a total of 140 patients underwent radical resection of Dukes B colorectal cancer by the same surgeon (C.C.). The relation between clinicopathologic variables and survival was estimated using the Kaplan-Meier method. The Cox proportional hazard regression model was used to identify the variables that can independently influence survival. A median of 12 lymph nodes (range 3-38) was examined per tumor specimen. The 5-year survival rate of Dukes B patients who had had eight or fewer lymph nodes examined after surgery was 54.9%, whereas the survival rate for those who had had nine or more lymph nodes examined was 79.9% (p < 0.001). Cox regression analysis identified the number of lymph nodes as the only independent prognostic factor (p = 0.01). Seventy patients with one to four metastatic lymph nodes (Dukes C patients) who had been operated on during the same period were included in the survival analysis for comparison. The 5-year survival rate of the Dukes B patients with eight or fewer lymph nodes examined was similar to that of the 70 Dukes C patients (54.9% and 51.8%, respectively). Examination of eight or fewer lymph nodes in Dukes B colorectal patients may be considered a high risk factor for missing positive lymph nodes in the surgical specimens. Our results suggest that harvesting and examining a minimum of nine lymph nodes per surgical specimen may be sufficient for reliable staging of lymph node-negative tumors.

Abstract
BACKGROUND It is unclear whether the extent of duodenal gastric metaplasia is due to Helicobacter pylori and/or acid. AIMS To investigate the role of Helicobacter pylori eradication in the regression of duodenal gastric metaplasia in patients with duodenal ulcer maintained in acid suppression conditions. METHODS . Duodenal (anterior, superior inferior walls of first part of duodenum) and gastric antrum biopsies were obtained from 44 Helicobacter pylori positive duodenal ulcer patients. Helicobacter pylori infection was diagnosed by rapid urease test, histology and 13C-Urea Breath Test. Patients were treated with 20 mg omeprazole tid associated with 250 mg clarithromycin and 500 mg amoxycillin four times daily for 10 days and maintained with 20 mg omeprazole daily for 18 weeks. Control endoscopies were performed at 6 and 18 weeks after beginning treatment. RESULTS Duodenal gastric metaplasia regression was observed in all (32/32) patients in whom Helicobacter pylori was eradicated, but in only 3 out of 6 patients in whom eradication was not achieved (p<0. 001). CONCLUSIONS . The present results suggest that Helicobacter pylori eradication associated with prolonged acid suppression may represent a good therapeutic strategy to achieve duodenal gastric metaplasia regression and highlight the combined role of acid and Helicobacter pylori in the pathogenesis of duodenal gastric metaplasia.

Abstract
BACKGROUND Intratumoral microvessel density (MVD) could be used as a prognostic factor in colorectal cancer. We retrospectively analyzed the value of microvessel count in predicting the clinical outcome of stage I and II (Dukes A and B) rectal cancer patients. METHODS Eighty-four patients who had undergone curative resection of lymph node-negative rectal cancer were included. Tumor type and differentiation, the depth of local invasion, venous invasion, the character of the invasive margin, and the degree of lymphocytic infiltration were evaluated for each tumor specimen. Immunohistochemical staining for the CD31 endothelial antigen was performed to highlight the microvessels. RESULTS The median value of MVD was 45 microvessels. Low MVD (microvessels < or = 45) was observed in 41 patients (48.8%), and high MVD (>45) was found in 43 (51.2%). The presence of conspicuous lymphocytic infiltration was significantly associated with increased vessel density. With uni- and multivariate survival analysis MVD did not show any prognostic significance. The character of the invasive margin was the only parameter with independent prognostic value. CONCLUSIONS MVD does not seem to provide any additional prognostic information when compared with standard histopathological parameters in lymph node-negative rectal cancer. It is likely that the strong association between MVD and the presence of conspicuous lymphocytic infiltration may interfere with its predictive value.

Abstract
We investigated the prognostic significance of microsatellite instability (MI) in 50 consecutive patients with sporadic mucinous colorectal cancer who had undergone only surgery. We evaluated MI and the pathological features with a possible prognostic value for each tumor, and the effect of the examined parameters on patients' outcome was statistically analyzed (univariate and multivariate analysis). All patients were followed-up for a minimum of 72 months or until death; in evaluating survival, only deaths of colorectal cancer were considered. DNA extracted from tumor sections and the corresponding normal tissue was analyzed by polymerase chain reaction at six microsatellite loci: D2S123, D3S1611, D3S49, D5S107, BAT26, BAT40. Alterations at two or more loci were detected in 36% of cases (MI+ tumors). MI+ and MI- cancers differed significantly in the pattern of growth, and most MI+ tumors showed an expanding type of growth (72.2%, P = .005). At univariate analysis, improved survival rate was significantly associated with MI, as well as with the following parameters: expanding cancer growth, Dukes stage, and absence of venous invasion. Nevertheless, at multivariate analysis, only the pattern of cancer growth and Dukes stage were independent prognostic factors, whereas the effect on survival of MI and venous invasion was found to be negligible. In our study, MI+ and MI- cancers differ only on the pattern of growth; therefore, our data suggest that the better survival rate in mucinous cancers with genomic instability is strictly related to their less aggressive type of growth.

Abstract
OBJECTIVE To find out whether tumour DNA content correlates with allelic loss of p53 and other pathological features in primary colorectal carcinomas. DESIGN Ongoing prospective study. SETTING University hospital, Italy. SUBJECTS 128 patients who had undergone radical resections for colorectal carcinoma. INTERVENTIONS Flow cytometric measurement of tumour DNA content and detection of allelic loss on the short arm of chromosome 17 by Southern blot (restriction fragment length polymorphism) analysis in fresh tumour specimens. MAIN OUTCOME MEASURES Correlation between DNA ploidy and deletion of p53, as well as between these two genetic events and clinicopathological variables. RESULTS Interpretable DNA histograms were obtained for 122 tumour specimens. Forty-three tumours (35%) were diploid and 79 (65%) aneuploid. The diploid tumours were significantly more common in the proximal colon (from the caecum to the splenic flexure) than in the distal colon (from the descending colon to the rectum) (p = 0.002). The allelic state on the short arm of chromosome 17 was evaluated in 80 heterozygous patients. Forty-four tumour specimens (55%) showed deletion of 17p. Allelic loss of p53 was significantly more common in the distal and rectal tumours than in the proximal ones (p < 0.0001). Aneuploidy was more common among those tumours which had shown deletion of p53 than in those that had not (p = 0.0008). CONCLUSIONS DNA aneuploidy was significantly associated with the deletion of the p53 gene. This suggests that the functional loss of p53 may favour the growth and establishment of an aneuploid cell population within tumours. Tumours of the proximal and distal colon differ in their genetic nature.

A rare case of adenocarcinoma of the duodenal bulb, arising from adenoma and submitted to Whipple's procedure is presented. A diagnostic delay of about 3 months, according to literature is observed. This delay is generally due to the low incidence of the illness, aspecific symptoms and frequent endoscopic and radiologic false negative, most of all in lesions of the third and fourth duodenal portions. Diagnostic tools for these duodenal tumors are endoscopy and upper gastrointestinal barium studies (UGI). CT is useful to determine preoperatively the stage of the illness and can occasionally show the primary duodenal lesion, as in this case. Surgical approach is still controversial, except in lesions of the second duodenal portion, where Whipple operation is the procedure of choice, if the tumor is resectable, of course. In the other duodenal portions some authors suggest segmental duodenal resections instead of Whipple's procedure.

Abstract
PURPOSE The clinical significance and prognostic value of the histopathologic parameters used in both the Dukes and Jass classifications were evaluated to select those with an independent effect on survival after radical surgery for colorectal cancer. METHODS The depth of local spread (limited to the bowel wall or extended beyond it), the number of metastatic lymph nodes (none, 1-4, more than 4), the character of the invasive margin (pushing or infiltrating), and the presence or absence of conspicuous peritumoral lymphocytic infiltration were assessed in 235 patients who had undergone radical resection for colorectal cancer. The influence of these variables on survival was studied by univariate and multivariate analysis. RESULTS No significant difference in survival was found between patients with conspicuous peritumoral infiltrate and those without it; moreover, multivariate analysis failed to show any independent prognostic value for either lymphocytic infiltration or depth of local invasion. However, the character of the invasive margin and the number of metastatic lymph nodes were identified as the only variables with any independent importance on survival. Based on these data, a new prognostic model may be proposed; it uses the character of the infiltrative margin as a discriminating factor among patients within the lymph node-negative (Dukes A and B stages) and lymph node-positive (Dukes C1 and C2 subsets) groups. A good prognosis for Dukes A, B, and C1 patients was associated with pushing tumors; C1 and C2 patients with infiltrating tumors had a poor prognosis. On the whole, the new prognostic model has allowed for the placement of 59.6 percent of our patients into groups that provide a confident prognosis. The clinical outcome of Dukes A and B patients with infiltrating tumors is still uncertain. CONCLUSIONS The character of the invasive margin is an important prognostic factor in colorectal cancer. The association of this parameter with the traditional Dukes classification may provide additional useful prognostic information and aid in the selection of those patients who could most benefit from adjuvant therapy.

Abstract
Primary hepatic carcinoid tumors are extremely rare; conversely, the liver is the most frequent site of metastases from gastrointestinal carcinoids. Clinically, primary lesions are characterized, in most cases, by the absence of an overt endocrine syndrome. Histologic findings and immunohistochemical demonstrations of chromogranin and neuron specific enolase, generally, enable the neuroendocrine origin of these neoplasms to be established. Prognosis after surgical treatment of primary hepatic carcinoids seems to be more favorable when compared with other hepatic carcinomas.

Abstract
Chordoma is a rare neoplasm arising in the cerebrospinal axis from nothochordal remnants. The commonest location is in the sacrococcygeal area, then in the sphenooccipital region and less frequently in other parts of the vertebral column. Chordoma has been found in all age groups, but the greatest incidence was found between the fifth and the seventh decades: there is a male predominance. Signs and symptoms of chordoma are related to tumor location and are often present for a long period of time because of the slow growth of the neoplasia. Sacrococcygeal chordomas may produce lower back pain, bladder or anorectal dysfunction or mass. Three histologic subtypes are currently considered: conventional, chondroid and dedifferentiated chordoma. Comparing with conventional chordoma, chondroid chordoma shows a better prognosis while dedifferentiated chordoma has a worse prognosis. However the malignant potential of chordoma is most likely due to incomplete surgical excision because of the multifocality of the neoplastic growth. For that reason, local recurrence is common and accounts in large part for the mortality for this tumor. The best treatment consists of a wide surgical excision coupled with adjuvant radiation therapy. We report a case of sacrococcygeal chordoma arised in a 48 year-old-man; the clinical features of the tumor showed a close resemblance with a pilonidal cyst. When the diagnosis of conventional chordoma was done the patient were treated by surgery and by intraoperative radiotherapy followed by external radiotherapy. This peculiar therapy was adopted in the attempt to reduce the risk of local recurrence. Six months after this treatment the patient was well and no signs of local recurrence was found by the magnetic resonance imaging.

Abstract
Two cases of adrenal cortical carcinoma in the pediatric age group are reported: the first case regards a fourteen month old female patient which presented with virilization and Cushing's syndrome: the second case regards a twelve year old boy with severe hypertension. Histopathologic distinction between benign and malignant adrenal cortical neoplasms is difficult: the usual cytologic criteria of benignity and malignancy in relation to prognosis are not very helpful while tumor size and tumor invasion appear to be the more important prognostic factors. Therefore early diagnosis, which is easier in the pediatric age because of the more frequent presentation of these neoplasms with hormonal effects, is essential.

Abstract
PURPOSE Colorectal signet-ring cell carcinoma (SRCC) is uncommon; discordant data have been previously reported about clinicopathologic features. Thirty-four cases of primary colorectal SRCC were retrospectively reviewed to clarify controversies. METHODS Primary colorectal SRCC was diagnosed when the following criteria were satisfied: 1) the tumor was primary; 2) histologic material was adequate; 3) signet-ring cell represented more than 50 percent of the cancer. RESULTS We identified 34 cases (1.1 percent) of 2,995 consecutive large bowel cancers collected at the Institute of Anatomic Pathology of Florence between 1985 and 1993. Patients ranged in age from 31 to 89 (mean, 63.5; median, 65) years; 19 were male, and 15 were female (male:female = 1.3:1). Fifteen tumors were located in the proximal colon, 11 in the rectum, and 8 in the distal colon. The gross shape was infiltrative in 24 cases and exophytic in 10; only 6 cases (17.6 percent) showed features of linitis plastica. Most cancers (61.8 percent) were Stage C, 29.4 percent were Stage B, and distant metastases were present in only three cases (8.8 percent). No Stage A case was found. Prognosis was extremely poor, and overall five-year survival rate was 9.1 percent. Survival was influenced significantly by tumor stage (P < 0.01). CONCLUSIONS Comparison of our data with the literature showed many differences that could be related to different applied diagnostic criteria. We underlined the importance of histology as reproducible criterion for diagnosis of primary colorectal SRCC.
