Abstract
A 56-year-old woman debuted with a palpable painless mass in the anterior thorax wall at the level of the second and third right parasternal intercostal space, which progressively increased in size over 5 months accompanied by localized skin rash, mild dyspnea and chest pain when changing position. Imaging studies showed a soft tissue mass measuring 75 × 62 mm and a density of 34 Hounsfield Units that had caused the lysis of the costal arches and grew expansively towards the anterior mediastinum, without identifying mediastinal adenopathies only by this imaging method. Core biopsy was performed, which was initially diagnosed as histiocytic sarcoma (HS); however, when the diagnostic panel was expanded to include molecular and NGS studies, the final diagnosis was anaplastic large cell lymphoma with ALK::ATIC fusion. Here, we report a very rare neoplasm with unusual clinical presentation, histopathology and molecular features.

Abstract
Small-cell lung carcinoma (SCLC) cell lines have been widely utilized as a preclinical model of this highly aggressive disease. However, since their creation decades ago, novel tumor entities have been defined that might clinicopathologically mimic SCLC, which notably includes thoracic SMARCA4-deficient undifferentiated tumor (SMARCA4-UT). Multiomic reassessment of the presumed SCLC cell lines with high YAP1 expression reveals that nearly all of these tumors represent unsuspected SMARCA4-UT. See related article by Ng et al., p. 1846.

Abstract
Thoracic SMARCA4-deficient undifferentiated tumor is a newly recognized disease entity characterized as a high-grade malignant neoplasm with an undifferentiated or rhabdoid phenotype. The tumor was initially identified as a subtype of thoracic sarcoma with SMARCA4 loss, but further investigation resulted in its classification as a subtype of epithelial malignancies in the current World Health Organization classification. SMARCA4-deficient undifferentiated tumor is highly aggressive and has a poor prognosis. Because of its rarity, an optimal treatment strategy has not yet been identified. In this review, we summarize the literature on SMARCA4-deficient undifferentiated tumor in terms of its clinical characteristics, diagnosis, treatment strategy and future perspectives.

Abstract
Background Thoracic SMARCA4-deficient undifferentiated tumor (SMARCA4-UT) is a distinct clinicopathological entity with an aggressive clinical course. Additionally, SMARCA4/BRG1 deficiency can be observed in a few patients with non-small cell lung cancer (NSCLC). We aimed to compare the clinicopathological, immunohistochemical and prognostic features of SMARCA4-deficient NSCLC (SMARCA4-dNSCLC) with those of thoracic SMARCA4-UT. Methods Patients with BRG1-deficient tumors in the lung or thorax were enrolled in the study from the Department of Pathology of West China Hospital, Sichuan University, from January 2014 to June 2022. We retrospectively collected the clinicopathological and immunohistochemical features and outcomes of these patients. Results Seventy-two patients had tumors in the lung or thorax with BRG1-deficient expression, including 52 patients with SMARCA4-dNSCLC and 20 patients with thoracic SMARCA4-UT. Among the patients with SMARCA4-dNSCLC, 98.1% were male, 85.7% were smokers, and 79.5% (35/44) had tumor-node-metas-tasis (TNM) III-IV tumors. Among the patients with thoracic SMARCA4-UT, all were males who smoked, and 93.75% (15/16) had TNM III-IV tumors. Pure solid architecture and necrosis were the predominant pathological features. Rhabdoid morphology was observed in some SMARCA4-dNSCLCs (10/52, 19.2%) and thoracic SMARCA4-UTs (11/20, 55%). In most patients with thoracic SMARCA4-UT, the tumors exhibited scattered weak expression or negative expression of epithelial markers, and positive expression of CD34 and Syn. Overall survival (OS) and progression-free survival (PFS) were not significantly different between patients with SMARCA4-dNSCLC and patients with thoracic SMARCA4-UT (p = 0.63 and p = 0.20, respectively). Conclusions Thoracic SMARCA4-DTs include SMARCA4-dNSCLC and thoracic SMARCA4-UT. Both have overlapping clinicopathological features and poor prognosis. We hypothesize that thoracic SMARCA4-UT may be the undifferentiated or dedifferentiated form of SMARCA4-dNSCLC. However, further studies with larger cohorts and longer follow-up periods are needed.

Abstract
NUT carcinoma and thoracic SMARCA4-deficient undifferentiated tumour are unique entities in the 5th edition of the World Health Organisation (WHO) Classification of Thoracic Tumours, whose definitions include molecular genetic abnormalities. These aggressive tumours require rapid work-ups on biopsies, but a broad list of differential diagnoses poses challenges for practising pathologists. This review provides an update on their key clinicopathological and molecular characteristics, as well as controversies regarding tumour classification and diagnostic strategy. Phenotypical assessment plays a substantial role in diagnosis because recurrent and predictable clinicopathological findings exist, including robust immunohistochemical phenotypes. Accurate diagnosis is crucial for appropriate management and a clearer understanding of the disease.

Abstract
Comprehensive genomic profiling (CGP) is implemented to detect actionable gene aberrations and design matched therapies. Although malignant thoracic tumors are commonly detected through respiratory endoscopy, it is questionable whether the small specimens obtained thereof are sufficient for CGP. Therefore, this study aimed to investigate the suitability of respiratory endoscopy for sampling primary and metastatic thoracic tumors for CGP. Patients whose specimens were collected through respiratory endoscopy and assessed by pathologists to determine their suitability for CGP at our institution between June 2019 and May 2022 were reviewed retrospectively. The suitability of each procedure as a sampling technique for CGP and, in the cases actually analyzed, the distribution of the detected gene aberration were assessed. In total, 122 patients were eligible for analysis; the median age was 61 (range, 29-86) years, and 71 (58.2%) patients were male. Primary intrathoracic tumors were found in 91 (74.6%) cases, including 84 (68.9%) primary lung cancers; the remaining thoracic metastases of extrathoracic origin included various types. The suitability rates of specimens obtained using conventional bronchoscopy with and without cryobiopsy, endobronchial ultrasound-guided transbronchial needle aspiration, and medical thoracoscopy were 82.8% (24/29), 70.4% (19/27), 72.9% (35/48), and 100% (18/18), respectively. Of the 96 cases judged suitable, 83 were subjected to CGP, and all but one were successfully analyzed. Finally, 47 (56.6%) patients had at least one actionable gene aberration and eight (9.6%) were treated with the corresponding targeted therapies. In conclusion, specimens obtained through respiratory endoscopy are suitable for CGP; medical thoracoscopy and cryobiopsy in conventional bronchoscopy are particularly useful.

Abstract
BACKGROUND Few studies have been conducted on comprehensive genomic profiling (CGP) panels in Japanese patients with thoracic malignancies after completing standard treatment. Consequently, its value in clinical practice remains unclear. METHODS We conducted a retrospective study of Japanese patients with thoracic malignancies who underwent CGP between June 2019 and November 2022 at our hospital. We evaluated the detection rate of actionable genetic alterations and percentage of patients who received genomically-matched therapy. Furthermore, we examined the value of the CGP panel in patients who underwent multiplex gene-panel testing prior to their initial treatment. This study was performed in accordance with the principles of the Declaration of Helsinki. RESULTS The study included 56 patients, of whom 47 (83.9%) had actionable genetic alterations and 8 (14.3%) received genomically-matched therapy. Of these, four patients were treated with approved drugs and three patients were treated with investigational agents. In addition, one patient was treated with approved drugs using the patient-directed care system. Of the 17 patients who had multiplex gene-panel testing performed at the start of their initial therapy, two (11.8%) were newly identified by the CGP panel and subsequently received genomically-matched therapy. EGFR L718Q and MET amplification were observed in two of the seven patients with epidermal growth factor receptor-tyrosine kinase inhibitor resistance. CONCLUSIONS The CGP panel could identify genetic alterations, thereby facilitating genomically-matched therapy, even in patients with thoracic malignancies who could not be identified using multiplex gene-panel testing.

Abstract
Nuclear protein in testis (NUT) carcinoma is an extremely rare and undifferentiated malignancy characterized by the rearrangement of NUT gene (NUTM1, Nuclear Protein in Testis). NUT carcinoma is a challenging disease which is difficult to diagnose and treat. Due to its rarity, lack of experience and need of specific molecular study it can be un/misdiagnosed. Therefore, NUT carcinoma should be included in differential diagnosis of poorly differentiated/undifferentiated and rapidly progressive malignancy in children and young adults, occurring in the head, neck or thorax. We report a case of NUT carcinoma presented with pleural effusion in adulthood.

Abstract
DEK::AFF2 carcinomas of the head and neck region have been recently described and reported to have aggressive clinical behavior but exceptional sensitivity to immunotherapy. We report a case of a 26-year-old female, never smoker, with a 5.2-cm left lower lobe central lung mass, with morphologic features identical to those reported for DEK::AFF2 head and neck carcinomas, including mixed papillary exophytic and invasive components, squamous/basaloid features, and monomorphic cytomorphology. DEK (exon 7)::AFF2 (exon 9) fusion was identified by whole-transcriptome RNA sequencing. This is the first report of thoracic DEK::AFF2 carcinoma, indicating that these tumors are not confined to the head and neck region but can involve both upper and lower respiratory tracts. This entity should be considered in the differential diagnosis of squamous cell carcinomas in never smokers lacking other known oncogenic mutations.

Abstract
BACKGROUND Challenging emerging entities with distinctive molecular signatures may benefit from algorithms for diagnostic work-up. METHODS Fusion sarcomas (2020-2021, during pandemic) were diagnosed by clinicoradiology, morphology, phenotype, and next-generation sequencing (NGS). RESULTS Six fusion sarcomas in two males and four females involved the chest-wall, neck, or extremities; ages ranged 2-73, median 18 years. Sizes ranged 5.3-25.0, median 9.1 cm. These include high grade 1) TPR-NTRK1 of proximal femur with a larger rounded soft tissue mass, previously considered osteosarcoma yet without convincing tumor matrix. A pathologic fracture necessitated emergency hemipelvectomy (NED) and 2) novel KANK1-NTRK2 sarcoma of bone and soft tissue with spindled pleomorphic to epithelioid features (AWD metastases). 3) Novel ERC1-ALK unaligned fusion, a low grade infiltrative deep soft tissue hand sarcoma with prominent-vascularity, myopericytoid/lipofibromatosis-like ovoid cells, and collagenized stroma, was successfully treated with ALK-inhibitor (Crizotinib), avoiding amputation. These NTRK and ALK tumors variably express S100 and CD34 and were negative for SOX10. 4) and 5) CIC-DUX4 round cell tumors (rapid metastases/demise), one with COVID superinfection, were previously treated as Ewing sarcoma. These demonstrated mild pleomorphism and necrosis, variable myxoid change and CD99 reactivity, and a distinctive dot-like-Golgi WT1 immunostaining pattern. 6) A chest wall/thoracic round cell sarcoma, focal CD34/ keratins/CK7, revealed nuclear-STAT6, STAT6-NAB2 by NGS, confirming malignant solitary fibrous tumor, intermediate-risk-stratification (AWD metastases). CONCLUSIONS Recent fusion sarcomas include new KANK1-NTRK2 and ERC1-ALK, the latter successfully treated by targeted-therapy. ALK/NTRK fusion partners TPR and KANK1 suggest unusual high-grade morphology/behavior. Clinicoradiologic, morphologic, and phenotypic algorithms can prompt molecular-targeted immunostains or NGS for final classification and promising inhibitor therapy.

Abstract
Most inflammatory myofibroblastic tumors (IMTs) harbor ALK fusions but oncogene fusions involving ROS1, RET, NTRK, and PDGFR also occur. The recognition that most IMTs harbor receptor tyrosine kinase fusions has provided a rationale for the use of tyrosine kinase inhibitors to target these oncogenic drivers in advanced IMTs. Crizotinib has been effective in ALK and ROS1-positive IMTs but resistance eventually develops. Here we report the successful use of lorlatinib in a patient with heavily pretreated ROS1-positive IMT of the chest wall with acquired crizotinib-resistance and metastasis to the brain.

Abstract
INTRODUCTION Inactivating mutations of the SMARCA4 (SWI/SNF-related, matrix-associated, actin-dependent regulator of chromatin, subfamily A, member 4) gene and/or loss of the BRG1 (brahma-related gene 1) protein defines SMARCA4-deficient thoracic sarcoma (SMARCA4-dTS), an aggressive neoplasm with a usually fatal outcome. Similar SMARCA4 mutations/BRG1 loss is also seen in a subset of non-small cell lung carcinomas (NSCLCs; SMARCA4-dNSCLCs) that lack alterations in currently targetable oncogenic drivers, that is, EGFR, ALK, and ROS1. There is limited knowledge on the cytomorphological features of these SMARCA4-deficient thoracic neoplasms. METHODS We retrospectively analysed the cytology of 2 cases each of SMARCA4-dNSCLC and SMARCA4-dTS to understand their cytomorphological overlap, if any, and identify features that would prompt testing for BRG1 loss. RESULTS All 4 patients were males presenting with advanced disease, with a mean age of 41.5 years (SMARCA4-dTS) and 58.5 years (SMARCA4-dNSCLC) at presentation. The cytology of the 2 SMARCA4-dTSs was strikingly similar, showing predominantly singly dispersed rhabdoid phenotype tumour cells with perinuclear cytoplasmic condensations in an inflammatory or necrotic background. The cytology raised suspicion for a wide range of differentials, including melanoma, high-grade lymphoma, germ cell tumour, undifferentiated carcinoma, and undifferentiated sarcoma. SMARCA4-dNSCLCs, on the other hand, were recognizable as poorly differentiated (adeno)carcinomas and were easily distinguished from SMARCA4-dTSs, with both cases showing cohesive clusters of frequently large tumour cells with abundant pale cytoplasm. CONCLUSION A diagnosis of SMARCA4-dTS is possible on cytology with appropriate ancillary testing and a high index of suspicion. The cytology of SMARCA4-dNSCLCs does not overlap with SMARCA4-dTS; rather, it resembles that of any poorly differentiated (adeno)carcinoma in the limited numbers analysed in this study.

Abstract
BACKGROUND Neuroblastoma is a biologically and clinically heterogeneous disease. Based on recent studies demonstrating an association between the primary tumor site, prognosis, and commonly measured tumor biological features, we hypothesized that neuroblastomas arising in different sites would show distinct genomic features reflective of the developmental biology of the sympathicoadrenal nervous system. METHODS We first compared genomic and epigenomic data of primary diagnostic neuroblastomas originating in the adrenal gland (n = 646) compared to thoracic sympathetic ganglia (n = 118). We also evaluated association of common germline variation with these primary sites in 1027 European-American neuroblastoma patients. RESULTS We observed higher rates of MYCN amplification, chromosome 1q gain, and chromosome 11q deletion among adrenal tumors, which were highly predictive of functional RNA signatures. Surprisingly, thoracic neuroblastomas were more likely to harbor ALK driver mutations than adrenal cases among all cases (odds ratio = 1.89, 95% confidence interval = 1.04 to 3.43), and among cases without MYCN amplification (odds ratio = 2.86, 95% confidence interval = 1.48 to 5.49). Common germline single nucleotide polymorphisms (SNPs) in BARD1 (previously associated with high-risk neuroblastoma) were found to be strongly associated with predisposition for origin at adrenal, rather than thoracic, sites. CONCLUSIONS Neuroblastomas arising in the adrenal gland are more likely to harbor structural DNA aberrations including MYCN amplification, whereas thoracic tumors show defects in mitotic checkpoints resulting in hyperdiploidy. Despite the general association of ALK mutations with high-risk disease, thoracic tumors are more likely to harbor gain-of-function ALK aberrations. Site of origin is likely reflective of stage of sympathetic nervous system development when malignant transformation occurs and is a surrogate for underlying tumor biology.

Abstract
Intratumor mutational heterogeneity has been documented in primary non-small-cell lung cancer. Here, we elucidate mechanisms of tumor evolution and heterogeneity in metastatic thoracic tumors (lung adenocarcinoma and thymic carcinoma) using whole-exome and transcriptome sequencing, SNP array for copy-number alterations (CNAs), and mass-spectrometry-based quantitative proteomics of metastases obtained by rapid autopsy. APOBEC mutagenesis, promoted by increased expression of APOBEC3 region transcripts and associated with a high-risk APOBEC3 germline variant, correlated with mutational tumor heterogeneity. TP53 mutation status was associated with APOBEC hypermutator status. Interferon pathways were enriched in tumors with high APOBEC mutagenesis and IFN-γ-induced expression of APOBEC3B in lung adenocarcinoma cells, suggesting that the immune microenvironment may promote mutational heterogeneity. CNAs occurring late in tumor evolution correlated with downstream transcriptomic and proteomic heterogeneity, although global proteomic heterogeneity was significantly greater than transcriptomic and CNA heterogeneity. These results illustrate key mechanisms underlying multi-dimensional heterogeneity in metastatic thoracic tumors.

Abstract
BACKGROUND SMARCA4-deficient thoracic sarcoma is a recently proposed entity of soft tissue tumors associated with an extremely poor prognosis. Its cytologic features have not been well described in the literature yet. CASE A woman in her early 30s who presented with chest pain was found to have a tumor in the right chest wall. Cytologic smears revealed numerous atypical round-to-polygonal cells appearing singly or in loosely cohesive clusters. These cells had a well-defined cell border, scant-to-moderate cytoplasm, and enlarged vesicular nuclei with prominent nucleoli. In addition, some cells with eosinophilic globular intracytoplasmic inclusions and eccentrically located nuclei, consistent with rhabdoid cells, were observed. Immunocytochemically, the cells were at least focally positive for cytokeratin CAM5.2 and CD34 and showed a significantly reduced BRG1/SMARCA4 expression. The diagnosis was confirmed by histological, immunohistochemical, and genetic analysis of a metastatic lesion to the left axillary lymph node. CONCLUSION Although the cytologic features of SMARCA4-deficient thoracic sarcoma are not fully unique, they are sufficiently characteristic to suspect this tumor in cases of supporting clinical and radiological features, which may promote additional immunological or molecular testing to establish a definitive diagnosis.

Abstract
Neuroblastoma is a unique malignancy in infants often presenting with either localized or metastatic disease. The study was carried out to explore the risk stratification of the poor prognosis for patients underwent surgical treatment.60 patients diagnosed with neuroblastoma were primarily enrolled in the study from April 2008 to April 2016. All the patients underwent surgical treatment and received 5-year follow-up. Clinical variables, including age, International Neuroblastoma Staging System (INSS) stage, tumor size and site, histology, and MYCN status were retrospectively analyzed, and EFS was chosen as the endpoint.The median age of patients was 8.2 months and average follow-up period was 40.2 ± 8.6 months. Among 60 patients, complete remission was achieved in 35 patients and partial remission in 14 subjects. Poor prognosis including patient death and tumor progression were overserved in 11 patients. Cox multifactor regression analysis revealed that age, histology and MYCN status had significant prognostic effect on event-free survival (EFS) rate for neuroblastoma patients underwent surgical treatment.In our study, we identified a series of prognostic factors including age, histology, and MYCN status predicting the prognosis of neuroblastoma patients after surgical treatment.

Abstract
INTRODUCTION Next-generation sequencing (NGS) allows for the identification of a growing number of therapeutic and prognostic molecular targets. However, NGS typically requires greater quantities of DNA than traditional molecular testing does. Endobronchial ultrasound transbronchial needle aspiration (EBUS-TBNA) is a minimally invasive procedure used to sample central thoracic lesions, but it is not well established whether this technique provides sufficient material for NGS. METHODS We performed a retrospective review of EBUS-TBNA at our institution (3/1/14-9/28/16). NGS was performed using a comprehensive hybrid-capture based assay (MSK-IMPACT) that detects >340 gene mutations. Samples found to be diagnostic for malignancy and for which MSK-IMPACT had been attempted were identified. Pathologic and clinical data were obtained from the medical record, and the results of MSK-IMPACT were examined. RESULTS In total, 784 EBUS-TBNA procedures were performed during the study period. MSK-IMPACT was requested for 115 malignant samples and was successful for 99 (86.1%), identifying an average of 12.7 mutations at a mean coverage depth of 806X. NGS was performed on paraffin-embedded cell blocks in 93 cases (93.9%) and on cell-free DNA in needle rinse fluid in 6 cases. The success rate of the assay improved significantly from the first third of cases (76.3%), to 92.3% for the final one-third of cases (p < 0.05). CONCLUSIONS EBUS-TBNA reliably provided adequate tissue for hybrid capture NGS, and is a suitable option for comprehensive NGS testing in patients with thoracic malignancies.

Abstract
INTRODUCTION The reported prevalence of ALK receptor tyrosine kinase gene (ALK) rearrangement in NSCLC ranges from 2% to 7%. The primary standard diagnostic method is fluorescence in situ hybridization (FISH). Recently, immunohistochemistry (IHC) has also proved to be a reproducible and sensitive technique. Reverse-transcriptase polymerase chain reaction (RT-PCR) has also been advocated, and most recently, the advent of targeted next-generation sequencing (NGS) for ALK and other fusions has become possible. This study compares anaplastic lymphoma kinase (ALK) evaluation with all four techniques in resected NSCLC from the large European Thoracic Oncology Platform Lungscape cohort. METHODS A total of 96 cases from the European Thoracic Oncology Platform Lungscape iBiobank, with any ALK immunoreactivity were examined by FISH, central RT-PCR, and NGS. An H-score higher than 120 defines IHC positivity. RNA was extracted from the same formalin-fixed, paraffin-embedded tissues. For RT-PCR, primers covered the most frequent ALK translocations. For NGS, the Oncomine Solid Tumour Fusion Transcript Kit (Thermo Fisher Scientific, Waltham, MA) was used. The concordance was assessed using the Cohen κ coefficient (two-sided α ≤ 5%). RESULTS NGS provided results for 77 of the 95 cases tested (81.1%), whereas RT-PCR provided results for 77 of 96 (80.2%). Concordance occurred in 55 cases of the 60 cases tested with all four methods (43 ALK negative and 12 ALK positive). Using ALK copositivity for IHC and FISH as the criterion standard, we derived a sensitivity for RT-PCR/NGS of 70.0%/85.0%, with a specificity of 87.1%/79.0%. When either RT-PCR or NGS was combined with IHC, the sensitivity remained the same, whereas the specificity increased to 88.7% and 83.9% respectively. CONCLUSION NGS evaluation with the Oncomine Solid Tumour Fusion transcript kit and RT-PCR proved to have high sensitivity and specificity, advocating their use in routine practice. For maximal sensitivity and specificity, ALK status should be assessed by using two techniques and a third one in discordant cases. We therefore propose a customizable testing algorithm. These findings significantly influence existing testing paradigms and have clear clinical and economic impact.

Abstract
A socially-housed New Zealand white rabbit presented with a large subcutaneous mass on the ventral thorax approximately 11 mo after the intrahepatic delivery of a suspension of VX2 carcinoma cells to induce hepatocellular carcinoma as part of a nanoparticle study. The mass and closely associated axillary lymph node were removed en bloc. Immunohistochemical staining identified the mass as an undifferentiated carcinoma. The rabbit demonstrated no appreciable pathology at the study end point at 16 mo after VX2 inoculation. An additional rabbit from the same VX2 injection cohort was found at necropsy to have an unanticipated intraabdominal mass, also identified as an undifferentiated carcinoma. This case report summarizes the molecular analysis of both tumors through a novel PCR assay, which identified the delayed and aberrant onset of VX2 carcinoma in an extended timeframe not previously reported.

Abstract
Nomogram has demonstrated its capability in individualized estimates of survival in diverse cancers. Here we retrospectively investigated 1195 patients with esophageal squamous-cell carcinoma (ESCC) who underwent radical esophagectomy at Zhejiang Cancer Hospital in Hangzhou, China. We randomly assigned two-thirds of the patients to a training cohort (n = 797) and one-third to a validation cohort (n = 398). Cox proportional hazards regression analyses were performed using the training cohort, and a nomogram was developed for predicting 3-year and 5-year overall survival rates. Multivariate analysis identified tumor length, surgical approach, number of examined lymph node, number of positive lymph node, extent of positive lymph node, grade, and depth of invasion as independent risk factors for survival. The discriminative ability of the nomogram was externally determined using the validation cohort, showing that the nomogram exhibited a sufficient level of discrimination according to the C-index (0.715, 95% CI 0.671–0.759). The C-index of the nomogram was significantly higher than that of the sixth edition (0.664, P-value<0.0001) and the seventh edition (0.696, P-value<0.0003) of the TNM classification. This study developed the first nomogram for ESCC, which can be applied in daily clinical practice for individualized survival prediction.

Abstract
CONTEXT Consumptive hypothyroidism (CH) is a rare form of hypothyroidism due to increased catabolic activity of type 3 iodothyronine deiodinase (DIO3) that can occur in large tumors. PATIENTs with CH typically present with markedly increased requirements for exogenous thyroid hormone and resolution after removal of the source of ectopic DIO3. DIO3 is encoded by DIO3, an imprinted gene expressed on the paternal allele that is located in a DIO3/delta-like 1 homolog (DLK1) gene locus regulated by a common control region, intergenic differentially methylated region (IGDMR). Because DIO3 is an imprinted gene, loss of imprinting at the IGDMR is thought to play a role in its increased expression; however, the molecular mechanism for DIO3 in CH currently is not known. OBJECTIVE The aim of the study was to determine the molecular mechanism for CH in an adult patient. SETTING The study was conducted in the Department of Endocrinology of a tertiary care center in Singapore. PATIENT We report the case of an adult Asian female patient with a large intrathoracic fibrous tumor and severe hypothyroidism that resolved after tumor resection. RESULTS The patient's tumor expressed increased levels of DIO3 and DLK1 mRNA and protein levels. Methylation-specific PCR of the IGDMR showed similar hypomethylation in placenta, thyroid, leukocytes, and tumor. Western blotting showed activation of sonic hedgehog (SHH) and MAPK signaling pathways that can increase DIO3 and DLK1 expression. CONCLUSIONS Loss of imprinting did not account for overexpression of DIO3 in the patient's tumor. Instead SHH and MAPK/ERK pathway activation was associated with systemic thyroid hormone catabolism and growth of the tumor. These findings raise the possibility that other tumors that have increased SHH and MAPK/ERK signaling also may have intratumor or systemic effects on thyroid hormone function.

Abstract
Pheochromocytomas (PCCs) and paragangliomas (PGLs) are rare neuroendocrine neoplasias of neural crest origin that can be part of several inherited syndromes. Although their mRNA profiles are known to depend on genetic background, a number of questions related to tumor biology and clinical behavior remain unanswered. As microRNAs (miRNAs) are key players in the modulation of gene expression, their comprehensive analysis could resolve some of these issues. Through characterization of miRNA profiles in 69 frozen tumors with germline mutations in the genes SDHD, SDHB, VHL, RET, NF1, TMEM127, and MAX, we identified miRNA signatures specific to, as well as common among, the genetic groups of PCCs/PGLs. miRNA expression profiles were validated in an independent series of 30 composed of VHL-, SDHB-, SDHD-, and RET-related formalin-fixed paraffin-embedded PCC/PGL samples using quantitative real-time PCR. Upregulation of miR-210 in VHL- and SDHB-related PCCs/PGLs was verified, while miR-137 and miR-382 were confirmed as generally upregulated in PCCs/PGLs (except in MAX-related tumors). Also, we confirmed overexpression of miR-133b as VHL-specific miRNAs, miR-488 and miR-885-5p as RET-specific miRNAs, and miR-183 and miR-96 as SDHB-specific miRNAs. To determine the potential roles miRNAs play in PCC/PGL pathogenesis, we performed bioinformatic integration and pathway analysis using matched mRNA profiling data that indicated a common enrichment of pathways associated with neuronal and neuroendocrine-like differentiation. We demonstrated that miR-183 and/or miR-96 impede NGF-induced differentiation in PC12 cells. Finally, global proteomic analysis in SDHB and MAX tumors allowed us to determine that miRNA regulation occurs primarily through mRNA degradation in PCCs/PGLs, which partially confirmed our miRNA-mRNA integration results.

Abstract
Although it rarely occurs in children, acute arterial thromboembolism can cause significant morbidity and mortality. Rapid diagnosis and prompt treatment can increase the chances of survival with a functional limb. We describe the case of a 10-year-old boy with acute bilateral lower extremity ischemia due to arterial thromboemboli originating from a rare cancer. We discuss diagnosis of and treatment strategies for acute arterial thromboembolism in the pediatric population, as well as the rare cancer the patient was diagnosed with.

Abstract
Most mantle cell lymphoma patients show remarkable disseminated disease at the initial diagnosis. We describe two cases of mantle cell lymphoma mainly involving thoracic lesions at the initial presentation of the disease. The clinical presentations were right hilar lymphadenopathy in one case and right pleural thickness in the other. The diagnosis of mantle cell lymphoma was confirmed by immunohistochemistry, including CD5, CD20, and cyclin D1, and the presence of t(11 ; 14)(q13 ; q32) by fluorescence in situ hybridization. These thoracic manifestations at the initial diagnosis should be taken into consideration for the clinical spectrum of mantle cell lymphoma.

Abstract
We here report a rare case of synovial sarcoma of the chest wall. A 71-year-old Japanese woman noticed a left anterior chest wall mass after twice having had surgery for lung cancer. An aspiration biopsy diagnosed synovial sarcoma. She then underwent a surgical resection. Pathology examination revealed a biphasic-type synovial sarcoma. When the prepared RNA from the tumor was subjected to a polymerase chain reaction, SYT-SSX1 fusion gene transcripts were demonstrated. Patients with the SYT-SSX1 fusion gene have a worse clinical outcome than patients with SYT-SSX2-positive tumors. After a second surgery, performed in 1 year later, there was no evidence of recurrence for 30 months; however, careful observation may be required.

Abstract
Valproic acid (VPA) is an established drug in the long-term therapy of epilepsy. Recently, VPA has demonstrated antitumor activity as a histone deacetylase (HDAC) inhibitor. In this study, the anticancer properties of VPA on neural crest-derived human tumor cell lines G361 melanoma, U87MG glioblastoma and SKNMC Askin tumor cells were investigated. The effect of VPA on cell growth, apoptotic activity and invasive ability were evaluated. Firstly, VPA induced cell growth inhibition and apoptotic activity, as demonstrated by sulforhodamine B protein assay, annexin V assay and by Western blot analysis for Bcl2 and Bax expression levels, in all three cell lines. In addition, VPA led to a decrease of HDAC-1 protein level, as assessed by Western blot analysis. Treatment with VPA caused a decrease in the invasive ability of all three cell lines. Since the invasion process involves a complex system of tightly regulated proteases, matrix metalloproteinases (MMPs) and their tissue-specific inhibitors (TIMPs), the effect of VPA on MMP and TIMP expressions was analysed. Exposure to VPA resulted in a decrease of MMP2 and MMP9 activity and expression level, as assesssed by gelatin zymography and Western blot analysis. In addition, exposure to VPA led to enhanced expression of TIMP1, as assessed by Western blot. Taken together, our results, besides providing further evidence that VPA may represent a promising therapeutic strategy in cancer treatment, may help in the design of new protocols geared at the treatment of neural crest-derived tumors.

Abstract
Recently, nuclear genes encoding two mitochondrial complex II subunit proteins, SDHD and SDHB, have been found to be associated with the development of familial pheochromocytomas and paragangliomas (hereditary pheochromocytoma/paraganglioma syndrome: HPPS). Growing evidence suggests that a mutation of SDHB is highly associated with abdominal (or thoracic) paraganglioma and the following distant metastasis (malignant paraganglioma). Previously, we identified a novel heterozygous G to A point mutation at the first base of intron 3 of the SDHB gene (IVS3+1G>A) in a malignant abdominal paraganglioma from a Japanese patient. In the present study, we report another case of SDHB mutation (R46Q) in a Japanese patient with both abdominal and thoracic paraganglioma following malignant metastasis. In addition, we identified an asymptomatic carrier of SDHB mutation in this family. Our report highlights the pathogenic role of the SDHB mutation (R46Q) in malignant paraganglioma. We also discuss the desired protocol that should be adopted to follow up an asymptomatic carrier of this mutation.

Abstract
Malignant mesothelioma is a devastating disease that has been associated with loss of Neurofibromatosis type 2 (NF2) and genetic lesions affecting RB and P53 pathways. We introduced similar lesions in the mesothelial lining of the thoracic cavity of mice. Mesothelioma developed at high incidence in Nf2;Ink4a/Arf and Nf2;p53 conditional knockout mice with median survival times of approximately 30 and 20 weeks, respectively. Murine mesothelioma closely mimicked human malignant mesothelioma. Conditional Nf2;Ink4a/Arf mice showed increased pleural invasion compared to conditional Nf2;p53 mice. Interestingly, upon Ink4a loss in the latter mice median survival was significantly reduced and all tumors were highly invasive, suggesting that Ink4a loss substantially contributes to the poor clinical outcome of malignant mesothelioma.

Abstract
Previous studies have indicated that genome instability is involved in the lymphomagenesis of pyothorax-associated lymphoma (PAL), which develops in patients with a long-standing history of pyothorax. One of the well-known causes of genome instability is telomere dysfunction. In the present study, the condition of telomeres was analyzed in the cell lines and clinical samples from PAL. Telomere length (TL) in PAL cell lines was extremely short (<4.5 kbp). TL in tumor samples was broad in range, and shorter than that in the peripheral blood leukocytes from the matched patients. Three of five PAL cell lines showed frequent loss of telomere signals (telomere erosion); however, telomerase activity in PAL cell lines was similar to that in Burkitt lymphoma cell lines. Rb expression was detected in three PAL cell lines and four of 15 clinical samples, respectively. Rb protein expressed in three PAL cell lines was heavily phosphorylated, indicating that function of Rb protein was suppressed. p16(INK4a) expression was not detected in either cell lines or clinical samples. The promoter region in p16(INK4a) was heavily methylated in all cell lines as well as the clinical samples. Inactivation of the p16(INK4a)/Rb pathway may allow continuous cell division and critical telomere shortening, which induce genome instability, finally leading to malignant transformation. Taken together, telomere dysfunction and inactivation of the p16(INK4a)/Rb pathway might play a role for PAL development.

Abstract
Desmoid tumors may occur sporadically or as part of the extraintestinal manifestations of familial adenomatous polyposis. Different phenotypes have been described and some genotype-phenotype correlations have been raised, associated with different sites of germline mutations in the adenomatous polyposis coli (APC) gene. We report on a 42-year-old woman ascertained for a large desmoid tumor of the anterior chest wall with pleural involvement, which persistently recurred despite a decade of treatment including hormone therapy, chemotherapy, and surgery. Spontaneous disappearance of the tumor was later noted after 1 year without any treatment and confirmed after 4 years of regular follow-up. Repeated colonoscopies were normal in the proband and DNA sequencing showed a frameshift mutation due to a single adenosine deletion at position 5772 (codon 1924). This mutation, located in the exon 15 at the 3' end of the APC gene, leads to an unusual and late onset phenotype. The pedigree revealed other isolated or familial adenomatous polyposis-associated cases of desmoid tumors. This family report shows that a molecular analysis of the APC gene should be performed in familial desmoid tumors for accurate genetic counseling and follow-up.

Abstract
We report on the case of a female twin with congenital thoracic neuroblastoma after conception via intracytoplasmatic sperm injection (ICSI). Birth occurred at 37 + 1-week gestation per primary sectio caesarea. Acute respiratory distress necessitated intubation and mechanical ventilation. Ultrasound and magnetic resonance imaging (MRI) showed a mass in the right upper thorax compressing the trachea. The tumor was subtotally excised and histological analysis revealed neuroblastoma. No further treatment was given. The residual primary tumor regressed spontaneously. Four years after diagnosis, both twins are healthy and normally developed.

Abstract
We present the case of large desmoid tumor of the anterior chest wall with pleural involvement, which persistently progressed despite hormonotherapy, chemotherapy and surgery. After many years of therapeutic failures, given the tumor size and its hemodynamic repercussions, the patient was presumed to be incurable and only supportive measures were given. One year later, the desmoid tumor had completely disappeared. Even though wide surgical excision is an essential element in the treatment of desmoid tumors, spontaneous regression may occur in very advanced disease.

Abstract
We report a case of intrathoracic desmoid tumor without familial adenomatous polyposis and demonstrate beta-catenin mutation of exon 3. A 15-year-old male presented with a desmoid tumor after having sustained an assault. In an examination for a mutation of the beta-catenin gene, an activating mutation from ACC (Thr) to GCC (Ala) at codon 41 was found. Immunohistochemical staining showed that accumulated beta-catenin protein was predominantly localized in the nuclei of desmoid cells, and cyclin D1 protein was also overexpressed. These findings might suggest that an activating mutation of the beta-catenin gene affected regulation of the cyclin D1 gene, resulting in the generation of intrathoracic sporadic desmoid tumor, which arose at the site of posttraumatic injury.

Abstract
In this retrospective study, we analyse epidemiology, clinical symptoms and therapeutic results in a group of 23 children with neuroblastoma. Half of them were less than 2 years of age; in 19 of 23, the primitive tumour was abdominal; 35% of them were initially metastatic. The overall survival was 83% at 5 years and the event free survival, 75% at 5 years. Pronostic factors are age, extension of the disease at diagnosis, biologic parameters and genetic study of the neuroblast cells (amplification of N-myc oncogen). Our study shows the deleterious effect of bone lesions.

Abstract
Synovial sarcoma (SS), an aggressive neoplasm accounting for up to 14% of soft tissue sarcomas, was recently recognized as a primary tumor in the lung and pleura. SS is characterized by the chromosomal translocation t(X;18)(SYT-SSX) found in more than 95% of the tumors. We report a cooperative study from the French Sarcoma Group and the Mesopath Group on 40 t(X;18)(SYT-SSX)-positive primary intrathoracic SS. There were 22 males and 18 females, whose age ranged from 16 to 79 years (median, 47 years). Neoplasms were mostly circumscribed and of large size (median, 7.5 cm; range, 2-16 cm). Thirty-nine tumors were monophasic SS, including 24 (60%) monophasic fibrous and 15 (37.5%) poorly differentiated cases, and one lesion was a biphasic SS. A larger proportion of poorly differentiated tumors were observed among intrathoracic SS as compared with soft tissue SS. Immunohistochemically, 90% of the cases reacted with at least one epithelial marker. CD34 was focally expressed in 3 cases. SYT-SSX1 fusion transcripts were detected in 22 cases (56.4%) and SYT-SSX2 fusion transcripts in 17 cases. Median and 5-year disease-specific survival in 33 patients was 50 months and 31.6%. Median and 5-year disease-free survival was 24 months and 20.9%. Patient sex, age, tumor size, histologic subtype, grade, and SYS-SSX fusion type had no significant impact on outcome. In conclusion, intrathoracic SS are rare but aggressive tumors with poor prognosis. In this unusual location, the detection of SYT-SSX fusion transcripts is a valuable diagnostic adjunct.

Abstract
Malignant rhabdoid tumor (MRT) is a highly malignant pediatric cancer, which arises in various sites such as the kidney, brain, and soft tissues. Cytogenetic studies have revealed alterations of 22q11 in MRT. Recently, deletions and mutations of the SNF5/INI1 locus in 22q11.2 have been reported in MRT, suggesting that SNF5/INI1 is a tumor suppressor gene for MRT. Here we report our molecular cytogenetic study for a newly established cell line from extrarenal MRT with t(1;22)(p36;q11.2). Consequently, the reciprocal translocation was associated with the interstitial deletion of a small segment including SNF5/INI1, and another, chromosome 22, showed terminal deletion, the breakpoint of which was located 70-80 kb centromeric to SNF5/INI1, resulting in homozygous deletion of SNF5/INI1 in this cell line.

Abstract
CONTEXT Germline mutations of the genes encoding succinate dehydrogenase subunits B (SDHB) and D (SDHD) predispose to paraganglioma syndromes type 4 (PGL-4) and type 1 (PGL-1), respectively. In both syndromes, pheochromocytomas as well as head and neck paragangliomas occur; however, details for individual risks and other clinical characteristics are unknown. OBJECTIVE To determine the differences in clinical features in carriers of SDHB mutations and SDHD mutations. DESIGN, SETTING, AND PATIENTS Population-based genetic screening for SDHB and SDHD germline mutations in 417 unrelated patients with adrenal or extra-adrenal abdominal or thoracic pheochromocytomas (n = 334) or head and neck paragangliomas (n = 83), but without syndromic features, from 2 registries based in Germany and central Poland, conducted from April 1, 2000, until May 15, 2004. MAIN OUTCOME MEASURES Demographic and clinical findings with respect to gene mutation in SDHB vs SDHD compared with nonmutation carriers. RESULTS A total of 49 (12%) of 417 registrants carried SDHB or SDHD mutations. In addition, 28 SDHB and 23 SDHD mutation carriers were newly detected among relatives of these carriers. Comparison of 53 SDHB and 47 SDHD total mutation carriers showed similar ages at diagnosis but differences in penetrance and of tumor manifestations. Head and neck paragangliomas (10/32 vs 27/34, respectively, P<.001) and multifocal (9/32 vs 25/34, respectively, P<.001) tumors were more frequent in carriers of SDHD mutations. In contrast, SDHB mutation carriers have an increased frequency of malignant disease (11/32 vs 0/34, P<.001). Renal cell cancer was observed in 2 SDHB mutation carriers and papillary thyroid cancer in 1 SDHB mutation carrier and 1 SDHD mutation carrier. CONCLUSIONS In contrast with SDHD mutation carriers (PGL-1) who have more frequent multifocal paragangliomas, SDHB mutation carriers (PGL-4) are more likely to develop malignant disease and possibly extraparaganglial neoplasias, including renal cell and thyroid carcinomas. Appropriate and timely clinical screening is recommended in all patients with PGL-1 and PGL-4.

Abstract
Synovial sarcoma (SS) is characterized by a chromosomal translocation resulting in the expression of an SYT-SSX chimeric transcript, usually SYT-SSX1 or SYT-SSX2. Synovial sarcoma typically originates in the limbs, and its location in the thorax is rare. Synovial sarcomas are usually classified into three histologic subtypes: biphasic, monophasic and poorly differentiated tumors. The detection of the characteristic chimeric transcript often contributes to a histopathological diagnosis, especially when the tumor arises in an unusual location. Previous studies have shown that SYT-SSX1 is the most common SYT-SSX fusion transcript in biphasic synovial sarcomas of the limbs. Here, we report two cases of synovial sarcoma originating in the thorax. The presence of SYT-SSX2 chimeric transcripts was confirmed by reverse transcript polymerase chain reaction (RT-PCR) and a direct sequencing analysis in both cases. The tumor in case 1 originated from the pericardium, which is an exceedingly rare site for primary synovial sarcoma; only three other cases of synovial sarcoma originating in the pericardium have been previously reported. Case 2 exhibited a biphasic synovial sarcoma of the mediastinum containing an SYT-SSX2 fusion transcript, which is a rare fusion type in biphasic synovial sarcomas of the limbs. We reviewed previous reports of thoracic synovial sarcomas containing an analysis of the SYT-SSX fusion transcript and found that case 2 in the present study was the first description of a biphasic synovial sarcoma of the thorax with an SYT-SSX2 fusion transcript. However, the number of reported cases was not sufficient to conclude that SYT-SSX2 fusion in biphasic synovial sarcoma of the thorax is, indeed, rare. Further genetic analysis is needed to fully understand the biological and clinical features of synovial sarcoma originating in the thorax.

Abstract
Mammary carcinoma frequently metastasizes to specific organs, including the regional lymph nodes, the lung and bone marrow. The mechanisms that guide organ-specific metastasis and the molecular players that are involved remain to be established. To gain insight into this problem, we used an orthotopic model of breast cancer in which the MDA-MB-435 cells are implanted into the mouse mammary fat pad. Sublines that preferentially metastasized to specific sites were isolated by excising metastatic tumors and growing explants of these tumors in culture. Cells lines that preferentially metastasize to the lymph node and thoracic cavity were obtained. The gene expression profiles of primary tumors from these sublines were then compared with cDNA arrays containing 5,800 known genes. In tumors that preferentially metastasize to the lymph node, several genes encoding adhesion and matrix proteins were upregulated. Genes encoding proteins involved in metabolism were downregulated. One of the upregulated genes in lymph-homing tumors was CD73. Immunohistochemistry showed that the CD73 protein is also upregulated in primary tumors of this cell line and that its expression is elevated in the lymph node metastases. CD73 is a transmembrane protein that has previously been implicated in the homing of normal lymphocytes to the nodes. This raises the hypothesis that tumors preferentially metastasize to lymph nodes by using CD73 to mimic part of the lymphocyte homing process.

Abstract
Like malignant fibrous histiocytoma (MFH), dedifferentiated liposarcoma represents a distinct subtype of liposarcoma and is characterized by an abrupt transition from well-differentiated liposarcoma (WDL) to highgrade dedifferentiated liposarcoma (DDL) . In addition, specific cytogenetic aberrations support the close biological relationship between WDL and DDL. Recent observations indicated the significance of cell cycle aberrations in tumor progression from the low-malignant, well differentiated to its dedifferentiated form, the prognosis of which is poor. Thus, alterations of mdm2 and p53 genes belong to the most frequently reported alterations in these two subtypes of liposarcoma. In previous investigations, we reported that loss of heterozygosity at the Rb gene locus, telomerase activity, hTERT, and c-Myc expression were associated with tumor progression in liposarcomas. In this study, we report on a case of a WD/DDL, in which both tumor components were separated using laser microdissection (P.A.L.M.) for the investigation of hTERT mRNA expression on a LightCycler. Macroscopically selected and histologically proven cryosections of low malignant and highly malignant tumor areas were cytogenetically investigated to confirm the diagnosis and to find additional chromosomal alterations with tumor progression.

Abstract
OBJECTIVE Pigment epithelium-derived factor is known to be an inhibitor of angiogenesis. We hypothesized that in vivo gene transfer of pigment epithelium-derived factor may inhibit tumor angiogenesis and growth in syngeneic models of thoracic malignancies. METHODS An adenovirus vector encoding the human pigment epithelium-derived factor cDNA (AdPEDF) was used to transduce human lung cancer cells in vitro. Transgene expression was assessed using Western analysis. Three different murine flank tumors (2 lung, 1 colon) were then established in syngeneic mice and treated intratumorally with phosphate-buffered saline, AdPEDF, or an empty vector (AdNull). Endpoints measured included transgene expression, tumor size, and animal survival, as well as microvessel density within the tumor. Additionally, a murine pulmonary metastasis model was established by intravenous injection of a syngeneic colon adenocarcinoma cell line expressing a marker gene (beta-galactosidase). One day later, treatment (phosphate-buffered saline, AdNull, or AdPEDF) was administered intrapleurally. Tumor burden (gross and histologic inspection, lung weight, and beta-galactosidase expression) was then evaluated 13 days after vector dosing, and survival was recorded. RESULTS AdPEDF-derived expression of pigment epithelium-derived factor was demonstrated in vitro and in vivo. In syngeneic murine lung cancer flank tumors, intratumoral administration of AdPEDF significantly inhibited tumor growth (P <.01), prolonged mouse survival (P <.01), and decreased microvessel density (P <.01) compared with control groups. In the pulmonary metastasis model, AdPEDF-treated mice exhibited significantly reduced lung lesions, lung weight (P <.0005), beta-galactosidase expression (P <.05), and animal survival was prolonged (P <.05). CONCLUSION Gene transfer of pigment epithelium-derived factor suppresses tumor vascularization and growth, while prolonging survival in syngeneic murine models of thoracic malignancies.

Abstract
Neurofibromas are benign tumors arising from neuroectodermal tissues. They may occur as solitary lesions, or multiple, in which case they are referred to as neurofibromatosis, or von Recklinghausen's disease. We report about a 17-year-old patient with neurofibromatous elephantiasis located in the lateral aspect of the left hemithorax. CT showed massive chest wall infiltration and retroperitoneal tumor growth, but no abnormalities of the cranium. Our surgical treatment consisted of a two-stage, palliative tumor debulking and defect coverage with a splitthickness skin graft. The operative and postoperative course was uneventful.
