Breast cancer is the most common malignancy in women. The most frequent metastatic sites are lung, bone, liver and brain. On the other hand, gastric metastases are rare. Synchronous bilateral breast cancer (SBBC) occurs rarely. Lobular carcinoma is the histological type most often associated with bilateral breast carcinomas and gastric metastases. We made a retrospective study including four patients followed in the Salah Azaiez Institute, for a bilateral breast cancer with gastric metastases. We analyzed the epidemiological, anatomoclinical and therapeutic particularities of this rare entity...

BACKGROUND: Osteosarcoma (OS) is a common bone malignant tumor, which is the eighth leading form of pediatric cancer. Despite the modern chemotherapeutic development of OS, a number of patients with OS have a high risk of lung metastasis and local relapse after chemotherapy. OBJECTIVE: This review study focused on the role of long non coding RNAs (lncRNAs) in OS progression, and presented update reports on OS treatment by targeting specific lncRNAs. METHOD: We have acquired information on OS and lncRNAs from scientific databases like google scholar, pubmed and scopus, and reviewed for this study...

Osteosarcoma harbors highly metastatic properties, accounting for postoperative recurrence and metastasis. Actin-like protein 6A (ACTL6A) regulates cell proliferation, migration and differentiation. However, the biologic role of ACTL6A in osteosarcoma remains unknown. In this study, the results showed that, by analysis of frozen fresh primary tumor tissues, matched non-cancerous bone tissues (NCBTs) and biopsy lung metastatic nodule tissues from 30 osteosarcoma patients after radical surgical resection, ACTL6A was overexpressed in osteosarcoma tissues compared with matched NCBTs, and its expression level was associated with osteosarcoma metastasis...

Non-small-cell lung cancer (NSCLC) is the third most common cancer that spreads to the bone, resulting in osteolytic lesions caused by hyperactivation of osteoclasts. Activating mutations in epidermal growth factor receptor-tyrosine kinase (EGF-TK) is frequently associated with NSCLC, and afatinib is a first-line therapeutic drug, irreversibly targeting EGF-TK. However, the effects of afatinib on osteoclast differentiation and activation as well as the underlying mechanism remain unclear. Afatinib dramatically suppressed receptor activator of nuclear factor κB (RANK) ligand (RANKL)-induced osteoclast formation in bone marrow macrophages (BMMs)...

BACKGROUND: Thyroid metastases to distant sites are uncommon incidents, most often metastasizing to the lungs and bones. Rates of metastasis to the kidney are particularly low, ranging from 2.8-3.8% for papillary and 6-20% for follicular variants of well-differentiated thyroid cancers (WDTCs). In rare instances, tumor-to-tumor metastasis between two true primary neoplasms can occurs. This medical phenomenon has previously occurred as a clear cell renal cell carcinoma (CCRCC) spreading to a WDTC...

Osteosarcomas are common bone malignancies in children and adolescents. LDOC1 (leucine zipper, down-regulated in cancer 1), a tumor suppressor, is down-regulated in many cancers. In this study, we investigated the role of LDOC1 in tumor metastasis and its prognostic significance in osteosarcomas. We established osteosarcoma cells stably expressing LDOC1, driven by an HIV-based lentiviral system. We investigated the impact of LDOC1 on migration and invasion abilities in these cells using a transwell assay. LDOC1-associated changes in expression of metastasis-promoting genes were analyzed with a quantitative real-time polymerase chain reaction primer array...

BACKGROUND: Lung cancer remains the most common cause of cancer-related death, with high rates of recurrence and poor outcomes. An abnormally high expression of activating transcription factor 3 (ATF3) in various cancers suggests an oncogenic role; however, its function in lung cancer is largely unknown. METHODS: Sixty-four pairs of lung cancer tissues were collected for ATF3 expression analysis by quantitative real-time PCR, immunoblotting, and immunohistochemistry staining...

Meningiomas represent the most common tumours of the central nervous system in adults. Risk factors include ionizing radiation, female hormones exposure, head trauma, cell phone use, breast cancer and family history of meningioma. Despite complete surgical resection, natural history of meningiomas often includes local recurrence but very few metastatic meningiomas have been reported. Here, we report the case of a metastatic meningioma. A 43-year-old woman was firstly treated for a symptomatic parietal meningioma WHO grade II by surgical resection followed by an irradiation of the surgical bed...

Lung cancer is the common cause of death from cancer, and most lung cancer patients die of metastasis. MicroRNAs (miRNAs) function as either oncogenes or tumor suppressors, playing crucial role not only in tumorigenesis, but also in tumor invasion and metastasis. There are several studies showed that miR-26a is involved in carcinogenesis, however, its role in tumor metastasis need to be elucidated. In this study, we showed that ectopic expression of miR-26a enhanced migration and invasion of lung cancer cells...

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: 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...
