Cancers evolve as a consequence of multiple somatic lesions, with competition between subclones and sequential subclonal evolution. Some driver mutations arise either early or late in the evolution of different individual tumors, suggesting that the final malignant properties of a subclone reflect the sum of mutations acquired rather than the order in which they arose. However, very little is known about the cellular consequences of altering the order in which mutations are acquired. Recent studies of human myeloproliferative neoplasms show that the order in which individual mutations are acquired has a dramatic impact on the cell biological and molecular properties of tumor-initiating cells...

BACKGROUND: Angiosarcoma is a rare malignant neoplasm derived from endothelial cells and its prognosis is poor because advanced angiosarcoma is resistant to standard chemotherapy, and new therapies are urgently needed. Heat shock protein 90 (HSP90) has been identified as a molecular chaperone that regulates various cancer-related proteins. Numerous clinical trials are testing the effectiveness of HSP90 inhibitors in various types of malignancies. OBJECTIVES: To investigate the role of HSP90 in the pathogenesis of angiosarcoma and whether inhibition of HSP90 may have anti-tumor activity...

Breast cancer is one of the most common malignant neoplasms diagnosed in females worldwide. Bone morphogenetic proteins (BMPs), which belong to the TGF-β superfamily, regulate a wide range of cellular responses including cell proliferation, differentiation, adhesion, migration and apoptosis in breast cancer. BMPs can bind to type I and II serine/threonine kinase receptors to regulate cell proliferation, invasion, migration, and apoptosis. Type I receptors are expressed in various breast cancer cell lines and primary tumor samples...

Patients with non-muscle-invasive or muscle-invasive bladder cancer undergoing surgery and currently available conventional therapy remain having a high risk of tumor recurrence or progression, respectively. Novel targeted molecular therapy is therefore expected to improve patient outcomes. Meanwhile, substantially higher incidence of bladder cancer in men has prompted research on androgen-mediated androgen receptor (AR) signaling in this malignancy. Indeed, preclinical evidence has suggested that AR signaling plays an important role in urothelial carcinogenesis and tumor outgrowth as well as resistance to some of the currently available conventional non-surgical therapies...

MicroRNAs (miRNAs) in cancer development have attracted much attention in recent years. miR-29 is known to critically affect cancer progression by functioning as a tumor suppressor. However, it may also act as an oncogene under certain situations. The prognostic value of miR-29 family in cancer progression is still under debate and reported results are inconsistent. Therefore, we reported here a meta-analysis and systematic review to analyze the prognostic role of miR-29 family in cancer. We screened 20 published studies and calculated pooled hazard ratios (HRs) and corresponding 95% confidence intervals (CIs) for overall survival (OS) or disease-free survival/recurrence-free survival (DFS/RFS)...

This review concentrates on three salivary gland tumors that have been accepted in the recent literature as new neoplastic entities: mammary analog secretory carcinoma (MASC), sclerosing polycystic adenoma (SPA) and cribriform adenocarcinoma of tongue and other minor salivary glands (CAMSGs). MASC is a distinctive low-grade malignant salivary cancer that harbors a characteristic chromosomal translocation, t(12;15) (p13;q25) resulting in an ETV6-NTRK3 fusion. SPA is a rare lesion often mistaken histologically for low-grade salivary carcinoma...

Oral metastatic tumor, which is uncommon and represents less than 1% of malignant oral neoplasms, usually arises from a primary mucosal or cutaneous cancer located in the head and neck regions. Metastasis of hepatocellular carcinoma (HCC) to the oral cavity, especially to gingiva, is extremely rare. A 50-year-old man, who was a chronic alcoholic and hepatitis B virus carrier, presented with abdominal distension and weight loss for the past 3 months. Three-phased contrast-enhanced abdominal CT revealed numerous conglomerated masses in the liver, suggesting huge HCCs arising in the background of liver cirrhosis with a large amount of ascites...

BACKGROUND: Childhood germ cell tumors (GCTs) are a rare assortment of neoplasms, with mostly unknown etiology, that are believed to originate very early in life. Few studies have examined risk factors by histologic subtype, despite evidence of different risk profiles. MATERIALS AND METHODS: In this population-based case-control study, 451 childhood malignant GCT cases ages 0-5 years were identified from the California Cancer Registry. Differentiating between common histologic subtypes, we identified 181 yolk sac tumors, 216 teratomas, and 54 rarer subtypes...

PURPOSE: Malignant phyllodes tumor of the breast (MPTB) accounts for less than 1% of whole breast neoplasm. Surgery is regarded as the primary treatment of choice in patients with MPTB, but the necessity of postoperative radiation therapy (RT) has been a subject of debate. Our aim was to evaluate effects of postoperative RT for MPTB using a large population database. METHODS: Using the Surveillance, Epidemiology, and End Results Program (SEER) database (1983-2013), clinico-pathologic prognostic factors were evaluated...

BACKGROUND: p16 (INK4A) (p16) functions as a tumor suppressor gene in various malignancies. Aberrant p16 methylation has been proposed to be essential in ovarian carcinogenesis. However, it is unclear whether p16 can be used as a diagnostic marker owing to the small sample sizes in previous studies. METHODS: To determine whether p16 promoter methylation is associated with epithelial ovarian cancer and can thus be used as a diagnostic marker, we performed a meta-analysis of published studies...

Background. Malignant neoplasms arising in Meckel's diverticulum, a vitelline duct remnant, are rare yet well-documented. Case Presentation. A 53-year-old previously healthy female presented with an enlarging midline abdominal wall mass. A computed tomography scan revealed a mass involving the linea alba, bilateral rectus abdominis, and subcutaneous fat. Extensive clinical workup failed to demonstrate other lesions, except local and paratracheal/hilar lymphadenopathy. Histopathologic examination of the resected tumor demonstrated a spectrum of serous neoplasia including serous cystadenoma, papillary serous carcinoma with numerous Psammoma bodies, and a poorly differentiated component...

The prostate-specific membrane antigen (PSMA) is expressed by both prostate cancer and other neoplasms. We report the case of a 65-year-old man with castration-resistant metastatic prostate cancer who underwent Ga-PSMA ligand PET/CT for restaging of disease. Ga-PSMA ligand accumulation was noted in a thyroid lesion, suspicious for thyroid malignancy on complementary ultrasound. Subsequent resection and histopathological analysis showed follicular thyroid adenoma with PSMA expression in tumor neovasculature endothelial cells, but not in thyroid epithelial cells...

: More and better accessibility to screening and increasing women's knowledge about the main symptomatic breast cancer signs result in detection of this neoplasm at an early stage, allowing a conservative surgical treatment. Breast conserving therapy (BCT) due to breast carcinoma involves the use of adjuvant radiotherapy which carries a risk the secondary radiation-induced malignancy. Angiosarcoma of the breast is an extremely rare radiation-induced malignant tumor following breast conserving therapy (BCT), first described by Schmidt in 1887...
