Osteosarcomas are malignant tumors of bone, most commonly seen in children and adolescents. Despite advances in modern medicine, the poor survival rate of metastatic osteosarcoma has not improved in two decades. In the present study we have investigated the effect of Riluzole on a human and mouse metastatic osteosarcoma cells. We show that LM7 cells secrete glutamate in the media and that mGluR5 receptors are required for the proliferation of LM7 cells. Riluzole, which is known to inhibit glutamate release, inhibits proliferation, induces apoptosis and prevents migration of LM7 cells...

PURPOSE: Tumor relapse is the most frequent cause of death in stage 4 neuroblastomas. Since genomic information on the relapse precursor cells could guide targeted therapy, our aim was to find the most appropriate tissue for identifying relapse-seeding clones. EXPERIMENTAL DESIGN: We analyzed 10 geographically and temporally separated samples of a single patient by SNP array and validated the data in 154 stage 4 patients. RESULTS: In the case study, aberrations unique to certain tissues and time points were evident besides concordant aberrations shared by all samples...

Bone marrow (BM) adipocytes are abundant in BM and may be involved in the process of bone metastasis. However, their behaviors in metastatic BM niches during bone metastasis have not been fully explored. In this study, intracardiac transplantation of B16-F10 melanoma cells into immunocompetent C57BL/6 mice was performed. Tibial marrow sections were stained with hematoxylin and eosin, Masson's trichrome, tartrate-resistant acid phosphatase, and fatty acid-binding protein 4 (FABP4) and analyzed using a histomorphometric system...

Three cases of metabolic bone disease in the setting of metastatic neuroendocrine tumor (NET) are illustrated with associated etiopathologies.  One of these cases harbored mixed lesions in the form of vertebral metastasis (biopsy proven) while the other skeletal lesions were caused due to metabolic bone disease related to multiple parathyroid adenomas. While the metastatic lesion was positive on 68Ga-DOTATATE positron emission tomography-computed tomography (PET-CT), the lesions of metabolic bone disease were negative and the 18F-fluoride PET-CT demonstrated the features of metabolic bone scan...

Isolated bone marrow metastasis of testicular tumor is very rare. Here, we report this case of a 21-year-old male who was admitted to our hospital with generalized body pain, which was severe and weakness for one month. He had a history of an operative intervention for the left testicular mass about 6 months ago which was diagnosed as mixed germ cell tumor on histopathological examination. The blood investigations showed anemia, low platelets, and elevated tumor markers. Bone marrow aspiration and biopsy examination showed metastatic deposits of mixed germ cell tumor...

Renal cell carcinoma (RCC) is a common tumor of the urinary tract. It is known to have variable presentations due to the extremely vascular nature of the organ. RCC are known to metastasize to lungs, bone, and brain commonly but atypical metastasis to various sites are reported in literature but as very rare pathology. We report a case of a 60-year-old female who presented with multiple inguinal and axillary lymph node enlargements which on excision biopsy showed metastatic RCC. RCC can present with synchronous metastatic deposits in the various organs...

BACKGROUND: Bone metastases (BMs) occur commonly in patients with metastatic renal cell carcinoma (mRCC). Tyrosine kinase inhibitors (TKIs) have improved the outcomes for patients with mRCC. However, data on the outcomes of mRCC patients with BMs treated with TKIs are limited. We describe the outcomes of patients with BMs treated with TKI therapy and compare them with the outcomes from a pre-TKI group. PATIENTS AND METHODS: Using an institutional tumor registry, a retrospective review of patients with mRCC from 2002 to 2003 and 2006 to 2007 was performed...

BACKGROUND: The skeleton is the most common site of colonization by metastatic cancers. Zoledronic acid (ZA) has been shown to be effective for the treatment of bone metastases regardless of whether the bone lesions are osteolytic or osteoblastic. Biochemical markers of bone turnover may be useful tools to quantify the degree of bone remodeling in the presence of bone metastases. The aim of this work was to establish the correlation between tumor dispersion (bioluminescence) and biochemical markers of bone turnover in two osteolytic and osteoblastic metastasis models in mice...

A 71-year-old female presented with melena and anemia. She had a past medical history of renal cell carcinoma diagnosed six years earlier and treated with left nephrectomy. Gastroscopy and colonoscopy showed no abnormalities. Renal cell carcinoma (RCC) is the third commonest urological malignancy, and approximately 25-50% of patients develop metastatic disease after surgery of the primary tumor. The most common sites of metastasis involve lung, lymph nodes, liver, bone and adrenal glands.

Bone marrow-derived mesenchymal stem cells (MSCs) can localize in injured, inflamed, and cancerous tissues after systemic infusion. However, the dynamic homing profile of MSCs in the peripheral blood is not well characterized. Here, using in vivo flow cytometry to noninvasively monitor the dynamics of fluorescence-labeled cells, we found different clearance kinetics of systemically infused MSCs between healthy and tumor mouse models. The circulation times of MSCs in healthy mice and mice with subcutaneous tumors, orthotopically transplanted liver tumors, or metastatic lung tumors were 30, 24, 18, and 12 hours, respectively, suggesting that MSCs actively home to tumor environments...

: Thyroid cancer with cranial metastasis in a pregnant woman is very rare. In the literature, most cases are diagnosed early from neurogenic signs or symptomatic thyroid gland. Pregnancy also contributes to a hesitation toward early surgical and medical treatments. We reported a scalp tumor in a physically healthy 37-year-old pregnant female with a follicular thyroid carcinoma (FTC) with lung, bone and cranial metastasis in initial presentation. Silent neurogenic and physical examinations make an early diagnosis very challenging...

INTRODUCTION: Phyllodes tumors (PTs) are rare fibroepithelial tumors of the breast which are classified as benign, borderline, or malignant. Malignant PTs account for <1% of malignant breast tumors, and borderline tumors have potential to progress to malignant tumors. Metastatic recurrences are most commonly documented in bone and lungs. We report an extremely rare presentation of recurrent malignant PTs involving the brain, lung, lymph nodes, and bone. CASE: A 66-year-old female presented with a large breast mass...

Metastasectomy represents the standard treatment for improving survival in patients with lung metastases (LMs) from bone (BS) or soft-tissue sarcoma (STS). Recently, radiofrequency ablation (RFA) of the LMs has been proved to be a useful option which can promise the similar effect to metastasectomy. The aim of this study was to determine prognostic factors, including tumor volume doubling time (TVDT), for post-metastatic survival in BS and STS patients treated with metastasectomy and/or RFA of the lung. Forty-eight patients with LMs were retrospectively reviewed...

Little is known about how megakaryocytes affect metastasis apart from serving as the source of platelets. We noted an increase in the number of megakaryocytes in the femurs of metastases-bearing athymic mice four weeks following intracardiac inoculation of MDA-MB-231 human breast cancer cells. How did the megakaryocytes relate to the metastases? Did megakaryocytes prepare a niche or did they increase in response to metastases? To test these possibilities, we examined two models of experimental metastasis, intracardiac inoculation of human MDA-MB-231 into athymic mice, and intramammary injection of mouse tumor cells, 4T1...

The hypothesis that microvesicle (MV)-mediated microRNA transfer converts non-cancer stem cells into cancer stem cells (CSCs) leading to therapy resistance remains poorly investigated. Here we provide direct evidence supporting this hypothesis, by demonstrating how MV derived from cancer associated fibroblasts (CAF) transfer miR-221 to promote hormonal therapy resistance (HTR) in models of luminal breast cancer. We determined that CAF-derived MV horizontally transferred miR221 to tumor cells and, in combination with hormone therapy activated an ERlo/Notchhi feed-forward loop responsible for the generation of CD133hi CSC...

Bone metastases are responsible for some of the most devastating complications of renal cell carcinoma (RCC). However, pro-metastatic factors leading to the highly osteolytic characteristics of RCC bone metastasis have barely been explored. We previously developed novel bone-seeking RCC cell lines by the in vivo selection strategy and performed a comparative proteome analysis on their total cell lysate. Here, we focused on STIP1 (stress-induced phosphoprotein 1), the high up-regulated protein in the bone-seeking cells, and explored its clinical relevance and functions in RCC bone metastasis...

BACKGROUND: Acute lymphoblastic leukemia (ALL), the commonest malignancy of childhood, is known to manifest with a myriad of atypical presentations. Nephromegaly is a rare presentation of childhood ALL with hepatic mass being even rarer. CASE PRESENTATION: We present a 3 year-old child with unilateral renal mass and hepatic mass lesion with normal blood counts, initially suspected to have metastatic Wilms tumor based on clinical, radiological and WT1 positivity on immunocytochemistry of renal mass...

Although the FAM84B gene lies within chromosome 8q24, a locus frequently altered in prostate cancer (PC), its alteration during prostate tumorigenesis has not been well studied. We report here FAM84B upregulation in DU145 cell-derived prostate cancer stem-like cells (PCSLCs) and DU145 cell-produced lung metastases compared to subcutaneous xenograft tumors. FAM84B protein was detected in bone metastases and primary PCs. Nanostring examination of 7 pairs of tumor adjacent normal and PC tissues revealed elevations in FAM84B mRNA levels in all carcinomas...

Although chondrosarcoma is a common malignant bone tumor, cases arising in the rib are relatively rare. We experienced a case of chondrosarcoma arising in the right 10th rib during follow-up after lung cancer surgery. Although the finding of an osteolytic mass suggested a metastatic bone tumor, 18F-fluorodeoxyglucose positron-emission tomography demonstrated low fluorodeoxyglucose uptake, and a primary bone tumor was suspected. The bone tumor was resected and diagnosed as chondrosarcoma. Four years after resection, there has been no recurrence or metastasis...
