Abstract
Undifferentiated pleomorphic sarcoma (UPS), once termed as malignant fibrous histiocytoma, has always been diagnosed exclusively in clinical practice because it lacks any defined resemblance to normal mesenchymal tissue. Although myxofibrosarcoma (MFS) has been separated from UPS due to its fibroblastic differentiation with myxoid stroma, UPS and MFS are still identified as a sarcoma group in terms of molecular landscapes. In this review article, we will describe the associated genes and signaling pathways involved in the process of sarcoma genesis and make a summary of conventional management, targeted therapy, immunotherapy, and some novel potential treatments of UPS/MFS. With the progressive advancements in medical technology and a better understanding about the pathogenic mechanism of UPS/MFS in the coming decades, new lights will be shed on the successful management of UPS/MFS.

Abstract
Pleomorphic undifferentiated sarcoma (PUS), also called malignant fibrous histiocytoma, is a soft tissue sarcoma which occurs predominantly in the extremities. Its origin is a poorly defined mesenchymal cell, which derives to histiocytic and fibroblastic cells. The patient, a 58 year-old man, presented a lesion located in the forearm composed by spindle cells and multinucleated giant cells, which expressed vimentin and adopted a histological pattern formed by irregular-swirling fascicles. Cells were cultured in vitro and a new cell line was established. We characterized this new cell line by histological analyses, cytogenetics (using G-bands and spectral karyotype technique) and cytometric analyses. Cells were grown in culture for more than 100 passages. They had elongated or polygonal morphology. The cells presented a saturation rate of 70,980 cells/cm2, a plating efficiency of 21.5% and a mitotic index of 21 mitoses per field. The cell line was tumorigenic in nude mice. The ploidy study using flow cytometry revealed an aneuploid peak with a DNA index of 1.43. A side population was detected, demonstrating the presence of stem and progenitor cells. Cytogenetics showed a hypotriploid range with many clonal unbalanced rearrangements. Loss of p53 gene was evidenced by MLPA. We describe, for the first time, the characterization of a new human PUS TP53-null cell line called mfh-val2. Mfh-val2 presents a wide number of applications as a TP53-null cell line and a great interest in order to characterize genetic alterations influencing the oncogenesis or progression of PUS and to advance in the biological investigation of this tumor.

Abstract
Cancer stem cells (CSCs) have been reported in many tissues. However, CSCs have yet to be identified in a human malignant fibrous histiocytoma (MFH) cell line. Elevated aldehyde dehydrogenase 1 (ALDH1) has been proposed as a stem cell marker for isolating CSCs from cancer. The aim of the present study was to identify a population with elevated ALDH in the human NMFH-1 cell line. ALDH⁺ and ALDH- cell populations were isolated and compared for CSC characteristics. ALDH enzymatic activity was used as a marker to identify the cells in the NMFH-1 line. Self-renewal, differentiation capacity, and tumorigenicity of the NMFH-1 ALDH⁺ cell population were then examined using a spheroid formation assay and xenograft model in nude mice. Chemoresistance levels, ABCG2 drug transport gene expression, and stem cell-associated gene expression were compared in these NMFH-1 populations. The ALDH⁺ population was better able to form spheres in anchorage-independent serum-starved conditions. Furthermore, the mRNA expression of key stem cell-related genes was enhanced in these cells. Increased expression of the drug transporter gene, ABCG2, was detected. Compared with ALDH-, the ALDH⁺ subpopulation had higher levels of chemoresistance to doxorubicin (DXR) and cisplatin (CDDP). Additionally, the ALDH⁺ cells more efficiently formed tumors when implanted into BALB/c nude mice. ALDH1 may therefore be used as a marker for the isolation of cells that exhibit several characteristics of CSCs from the NMFH-1 cell line. This finding may lead to the development of novel therapies to specifically kill ALDH1⁺ subpopulations (CSCs).

Establishment of a new human pleomorphic malignant fibrous histiocytoma cell line, FU-MFH-2: molecular cytogenetic characterization by multicolor fluorescence in situ hybridization and comparative genomic hybridization. JOURNAL OF EXPERIMENTAL & CLINICAL CANCER RESEARCH : CR 2010; 29:153.

Abstract
Background Pleomorphic malignant fibrous histiocytoma (MFH) is one of the most frequent malignant soft tissue tumors in adults. Despite the considerable amount of research on MFH cell lines, their characterization at a molecular cytogenetic level has not been extensively analyzed. Methods and results We established a new permanent human cell line, FU-MFH-2, from a metastatic pleomorphic MFH of a 72-year-old Japanese man, and applied multicolor fluorescence in situ hybridization (M-FISH), Urovysion™ FISH, and comparative genomic hybridization (CGH) for the characterization of chromosomal aberrations. FU-MFH-2 cells were spindle or polygonal in shape with oval nuclei, and were successfully maintained in vitro for over 80 passages. The histological features of heterotransplanted tumors in severe combined immunodeficiency mice were essentially the same as those of the original tumor. Cytogenetic and M-FISH analyses displayed a hypotriploid karyotype with numerous structural aberrations. Urovysion™ FISH revealed a homozygous deletion of the p16INK4A locus on chromosome band 9p21. CGH analysis showed a high-level amplification of 9q31-q34, gains of 1p12-p34.3, 2p21, 2q11.2-q21, 3p, 4p, 6q22-qter, 8p11.2, 8q11.2-q21.1, 9q21-qter, 11q13, 12q24, 15q21-qter, 16p13, 17, 20, and X, and losses of 1q43-qter, 4q32-qter, 5q14-q23, 7q32-qter, 8p21-pter, 8q23, 9p21-pter, 10p11.2-p13, and 10q11.2-q22. Conclusion The FU-MFH-2 cell line will be a particularly useful model for studying molecular pathogenesis of human pleomorphic MFH.

Abstract
The presence of a near-haploid karyotype is a rare finding in human malignancies, most frequently occurring in acute leukemia. In solid tumors, a near-haploid karyotype has been reported in fewer than 40 cases. We report two nearly identical near-haploid karyotypes from two distinctly different tumor types. The first case is a biphasic malignant mesothelioma from a 53-year-old white woman forming a large retroperitoneal mass. Cytogenetic evaluation revealed a primary hyperdiploid cell population as well as near-haploid and hypertetraploid populations with an overall karyotype of 27,XX,i(5)(p10),+7,add(15)(p11.2),+dic(1;20)(p13;p13)[2]/54,idemx2[90]/101-108,idemx4[19]. The second case is a large pelvic mass from a 48-year-old man. Histologic examination identified a malignant peripheral nerve sheath tumor displaying a karyotype of 26,X,+i(5)(p10),+7,der(15)t(1;15)(q12;p12),+20[5]/52,idemx2[20]. Herein we discuss the potential relationship between these two disparate neoplasms with nearly identical near-haploid karyotypes and present a literature review.

Abstract
Malignant fibrous histiocytoma (MFH) occurs most commonly in the extremities and trunk, but rarely in the intestine. Here we report two cases of primary intestinal MFH. The first case was a 70-year old man admitted for recurrent right lower quadrant abdominal pain. At laparotomy, a tumor was found originating from the cecum, with a suspicious metastatic nodule on the surface of the right lobe of the liver. A right hemicolectomy was performed followed by an ileotransverse end-to-end anastomotic reconstruction. The second case was a 43-year old man with intussusceptions of the small intestine. An emergent laparotomy revealed 4 pedunculated masses in the small bowel and a partial resection of the small intestine was performed. Though the symptoms were not typical, based on histological and immunohistochemical studies, the patients were diagnosed as MFH of the intestine. They were not treated with chemotherapy or radiotherapy and both died within 3 mo. MFH of the intestine is an extremely rare neoplasm with an aggressive biological behavior. The pathogenesis of this disease has not been clarified to date. Complete surgical excision is preferred, adjuvant chemotherapy or radiotherapy may be advisable.

Abstract
We established a novel human myxofibrosarcoma cell line NMFH-1 and analyzed it with spectral karyotyping and comparative genomic hybridization (CGH). NMFH-1 cells are composed of two different types of cells, small, spindle-shaped mononuclear cells and bizarre multinucleated giant cells, which were maintained in vitro over 200 passages. Xenografted tumor showed typical features of myxofibrosarcoma, which included bizarre multinucleated giant cells. Cytogenetic analyses revealed complex abnormalities, including a t(17;22)(q2?2;q13), which has been found in dermatofibrosarcoma protuberans. Subsequent reverse-transcription polymerase chain reaction revealed that the cell line did not have the COL1A1-PDGFB gene fusion. Significant gains of the 1q12 approximately q23 and 8q13 approximately qter regions and loss of the 9p21 approximately pter and 13q12 regions often found in MFH were observed by CGH analysis. We investigated the origin of multinucleated giant cells in xenografted tumor through DNA in situ hybridization. In this system, the human-specific Alu sequence and the mouse L1 sequence were used as specific cell markers of identity. In situ hybridization revealed neoplastic proliferation of the multinucleated giant cells of human origin.

Abstract
Inflammatory leiomyosarcoma, a rare entity first described in 1995, has been characterized by smooth muscle differentiation, a near-haploid karyotype, and a surprisingly good prognosis. The morphology is similar to that of conventional leiomyosarcoma admixed with a chronic inflammatory infiltrate. Thus far, only 15 cases have been reported in the English language literature. We report the clinical and pathological features of 3 additional cases of inflammatory leiomyosarcoma. Two women (ages 64 and 25, respectively) and 1 man (age 32) presented with a thigh, ovary, and lung mass, respectively. Inflammatory symptoms, such as anorexia, fever, night sweats, abdominal pain, and diarrhea, coincided with the thigh and ovarian primaries. Immunohistochemical studies revealed diffuse positivity for desmin and poor expression for other smooth muscle and skeletal muscle markers (muscle-specific actin [0/3], alpha-smooth muscle actin 1/3 [focal], calponin [1/3], caldesmon [0/3], and myogenin [0/3]). CD68 was diffusely positive in both the histiocytes and spindle cell component in all cases. Ultrastructural evaluation of 1 case (lung primary) lacked definitive smooth muscle differentiation. Cytogenetic analysis in 1 of 2 cases that were karyotyped, identified a near-haploid karyotype, which has been reported in other cases of inflammatory leiomyosarcoma. The other case showed 2 clonal populations of cells with interstitial deletions of the short arm of chromosome 8 and the long arm of chromosome 9, respectively. The case without cytogenetic data was intimately associated with an ovarian mature teratoma. These data also suggest that inflammatory leiomyosarcoma may lack smooth muscle differentiation, characterized by diffuse immunoreactivity for desmin but lack of immunoreactivity for alpha-smooth muscle actin, calponin, and caldesmon. In addition, 2 of the 3 cases developed distant metastases to the lungs, which suggests that these lesions may have a worse prognosis than previously believed.

Abstract
Although a number of malignant fibrous histiocytoma (MFH) cell lines have been reported, their characterization at a molecular cytogenetic level has not been fully established. In this study, we established a new human cell line, designated as FU-MFH-1, from a storiform-pleomorphic MFH arising in the retroperitoneum of a 61-year-old woman, and applied comparative genomic hybridization (CGH) and fluorescence in situ hybridization (FISH) with chromosome painting probes for the characterization of chromosome alterations. FU-MFH-1 cells were spindle, round, or polygonal in shape with oval nuclei, and were maintained continuously in vitro for over 50 passages for more than 12 months. G-banding analysis was performed and FU-MFH-1 revealed a complex karyotype with an abnormal chromosome 19 containing a homogeneously staining region (hsr). CGH analysis showed a high-level amplification of 12q13-->q21. The high-level amplification detected by CGH was refined by FISH. These results showed that the hsr was composed of amplified DNA sequences from 12q. Our study emphasizes the usefulness of CGH as a powerful tool for chromosomal localization of amplified sequences. The FU-MFH-1 cell line should be useful for biologic and molecular pathogenetic investigations of human MFH.

Abstract
We analysed six malignant peripheral nerve sheath tumors (MPNSTs) from four patients using metaphase preparations and compared the results with those obtained by using comparative genomic hybridization (CGH). All six tumors showed structural and numerical chromosomal aberrations, mostly of chromosomes 1, 5, 7-10, 14-17, 19, 21, and 22. The number of chromosomes per tumor cell ranged from 42 to 104. We could not find a recurrent specific pattern of structural changes after comparing the MPNSTs of different patients. However, aberrations of different tumors from the same patient were nearly identical. In the four patients, we found a total of 117 breakpoints, mostly in 21q11.2 (seven times), in 8q11.2 and 14q10 (six times each), in 5q11.2 and 15q26 (four times each), in 8p11.2, 10q11.2, 16q22, 19q13.3, and 22q10 (three times each). In three MPNSTs, double minute chromosomes (dmin) we detected with metaphase investigations and high-level amplifications by using CGH, respectively. C-MYC gene amplification and loss of the P53 gene could be ruled out by locus-specific probes for the common gain of 8q and for losses of 17p. When comparing the CGH results with those of karyotyping an overlap in the most frequent gains in 7q, 8q, 15q, and 17q was observed. However, we found more frequent losses in 19q in the metaphase investigations.

Abstract
The human COMA cell line has been established from a storiform pleomorphic malignant fibrous histiocytoma (MFH). As expected for this tumor type, a very complex karyotype was observed after R-banding analysis. An extensive analysis by 24-color painting, comparative genomic hybridization (CGH), and fluorescence in situ hybridization (FISH) was performed. Twelve complex marker chromosomes recurrently observed were clearly identified; among them, three were systematically present in all analyzed metaphases. Amplifications detected by CGH were refined by FISH with probes specific for various candidate loci. A significant aneuploidy and numerous micronuclei were observed, which could be related to the anomalies of centriole numbers detected in a proportion of cells. Such an analysis, performed on a series of MFH cell lines, would allow the delineation of the genomic alterations specific for the oncogenesis or progression of this complex tumor type or both.

Abstract
To search for new recurrent genetic aberrations in malignant fibrous histiocytoma (MFH), a combination of conventional cytogenetic, comparative genomic hybridization (CGH), and Southern blot analyses was applied to a series of 34 tumors. Cytogenetic analysis revealed the presence of multiple structural and numerical aberrations, including marker chromosomes, telomeric associations, double minutes, and ring chromosomes. The most frequent genomic imbalances in this series of neoplasms as detected by CGH were gains of 1q21-q22 (69%), 17q23-qter (41%), and 20q (66%), and losses of 9p21-pter (55%), 10q (48%), 11q23-qter (55%), and 13q10-q31 (55%). Southern blot analyses with p16(INK4A) (CDKN2A; 9p21) and RB1 (13q14) probes provided clear indications for frequent deletions of these tumor suppressor genes, and as such, substantiated the CGH results. Additionally, examination of the TP53 and MDM2 genes showed frequent loss and amplification, respectively. These data indicate that genes involved in the RB1- and TP53-associated cell cycle regulatory pathways may play prominent roles in the development of human MFH.
