Hideaki Tsuyoshi, Yoshio Yoshida
Uterine leiomyosarcoma (u{\hyphen}LMS) and endometrial stromal sarcoma (ESS) are among the most frequent soft tissue sarcomas, which, in adults, lead to fatal lung metastases and have an extremely poor prognosis. Due to their rarity and heterogeneity, there are no suitable biomarkers for diagnosis and prognosis, though some biomarker candidates have appeared. Recently, The Cancer Genome Atlas (TCGA) projects dealing with u{\hyphen}LMS confirmed mutations and deletions in RB1, TP53, and PTEN. In addition, whole{\hyphen}exome sequencing of u{\hyphen}LMS has confirmed and demonstrated frequent alterations in TP53, RB1, α-thalassemia/mental retardation syndrome X-linked (ATRX), and mediator complex subunit 12 (MED12)...

A 24-year-old woman was admitted to the hospital for abdominal pain. Abdominal contrast-enhanced computed tomography( CT)revealed a cystic mass measuring 11×8 cm in the left lobe of the liver with extravasation. Vascular embolization was performed, but extravasation remained on CT images. She was then transferred to our hospital. We performed an emergency extended left hepatectomy. Histopathological examination revealed solid proliferation of spindle-shaped cells. Immunohistochemical staining showed that the tumor cells were positive for vimentin and negative for AE1/AE3...

Sarcoma is well-known rare cancer with few therapeutic options. Recent comprehensive genomic analyses of adult soft tissue sarcoma revealed few somatic mutations and massive copy number variations(CNVs)by the specific chromosomes. Those features are quite different from the genomics of carcinoma such as lung and colon cancers in which driver and passenger mutations play a central role in the pathogenesis. Furthermore, it has been demonstrated that substantial population of sarcoma patients has pathological germline variants of cancer predisposition genes...

BACKGROUND: Alveolar soft part sarcoma (ASPS) is a rare soft tissue tumor that typically affects young patients. Similar to other soft tissue sarcomas, it has high pulmonary metastasis ability, whereas compared with other soft tissue sarcomas, it has high brain metastasis ability. Because of the rarity of the disease, most studies on ASPS have been case reports and small series studies. METHOD: We performed a retrospective study to evaluate the clinical and pathological features and oncological results in a consecutive series of patients with localized or metastatic ASPS treated at our institute between 1994 and 2014...

Pelvic Ewing sarcoma is associated with a worse prognosis. Thromboembolic events are relatively common in pediatric patients with cancers including sarcomas. We have presented a case of Ewing sarcoma arising from the left iliac bone with tumor thrombus of inferior vena cava (IVC) which was obtained complete response by both chemotherapy and irradiation. Magnetic resonance imaging (MRI) scan demonstrated that the tumor arising from the left iliac bone extended into the left side of sacral bone, suggesting the difficulty of surgical resection...

Non-small-cell lung cancer (NSCLC) is a leading cause of cancer death worldwide, with 25% of cases harboring oncogenic Kirsten rat sarcoma ( KRAS ). Although KRAS direct binding to and activation of PI3K is required for KRAS -driven lung tumorigenesis, the contribution of insulin receptor (IR) and insulin-like growth factor 1 receptor (IGF1R) in the context of mutant KRAS remains controversial. Here, we provide genetic evidence that lung-specific dual ablation of insulin receptor substrates 1/2 ( Irs1 / Irs2 ), which mediate insulin and IGF1 signaling, strongly suppresses tumor initiation and dramatically extends the survival of a mouse model of lung cancer with Kras activation and p53 loss...

Background: The aberrant status of target genes and their associations with clinicopathologic characteristics are still unclear in primary lung adenocarcinoma. Methods: The common mutations and translocations of nine target genes were evaluated in 1,247 specimens of surgically-resected primary lung adenocarcinoma. Immunohistochemistry was used to analyze the expressions of programmed death-1 (PD-1)/programmed death-ligand 1 (PD-L1) in 731 specimens. The frequency of the aberrations and their associations with clinicopathologic characteristics were analyzed...

Ewing sarcoma (ES) is the second most common bone malignancy affecting children and young adults with poor prognosis due to high metastasis incidence. Our group previously described that EphA2, a tyrosine kinase receptor, promotes angiogenesis in Ewing sarcoma (ES) cells via ligand-dependent signaling. Now we wanted to explore EphA2 ligand-independent activity, controlled upon phosphorylation at S897 (p-EphA2S897 ), as it has been linked to metastasis in several malignancies. By reverse genetic engineering we explored the phenotypic changes after EphA2 removal or reintroduction...

OBJECTIVE: To determine if there are differences in overall survival (OS) or event-free survival (EFS) in patients with and without concomitant extra-adrenal metastases undergoing adrenal metastasectomy. BACKGROUND: There is growing interest in the use of local therapies in patients with oligometastatic disease. Previously published series have indicated that long-term survival is possible with resection. Adrenalectomy has been used to treat adrenal metastases in select patients...

Patient tumors grew in Gelfoam® histoculture with maintenance of tissue architecture, tumor-stromal interaction, and differentiated functions. In this chapter, we review the use of Gelfoam® histoculture to demonstrate proliferation indices of major solid cancer types explanted directly from surgery. Cell proliferation was visualized by histological autoradiography within the cultured tissues after [3 H]thymidine incorporation by the proliferating cells. Epilumination polarization microscopy enables high-resolution imaging of the autoradiography of each cell...

Next generation sequencing (NGS) is becoming increasingly integrated into oncological practice and clinical research. NGS methods have also provided evidence for clonal evolution of cancers during disease progression and treatment. The number of variants associated with response to specific therapeutic agents keeps increasing. However, the identification of novel driver mutations as opposed to passenger (phenotypically silent or clinically irrelevant) mutations remains a major challenge. We conducted targeted exome sequencing of advanced solid tumors from 44 pre-treated patients with solid tumors including breast, colorectal and lung carcinomas, neuroendocrine tumors, sarcomas and others...

In bone and soft tissue sarcomas (STS), surgery was to the only local curative treatment, but recently, radiation therapy and interventional radiology has evolved to potentially curative treatment, namely in small size tumours. Indication for local treatment in STS needs validation in multidisciplinary team. Most will agree on local treatment for single metastatic location in a well-controlled disease and for no local treatment in a rapidly evolving multi-metastatic disease. The challenge is in patients who are in between, for whom benefit of disease control on overall survival should be evaluated...

AIMS: Epithelioid sarcoma is a soft tissue sarcoma associated with a high rate of local recurrence after wide resection and high incidence of distant metastasis. Little is known about the clinical course and response to systemic treatments in epithelioid sarcoma patients. We carried out a retrospective analysis of clinical data from epithelioid sarcoma patients to provide a reference for the design of future epithelioid sarcoma-specific studies. PATIENTS AND METHODS: Data from patients with epithelioid sarcoma entered in prospective multi-sarcoma phase II/III trials were pooled: EORTC trial 62012 (doxorubicin versus doxorubicin/ifosfamide), 62043 (pazopanib), 62072 (pazopanib versus placebo) and 62091 (doxorubicin versus trabectedin)...
