BACKGROUND: Cytokines are the communicators of immune system and are involved in all immune responses. The aim of this study was to assess the correlation among plasma cytokines, patient and tumor characteristics, and clinical outcome in chemonaive testicular germ-cell tumor (TGCT) patients. PATIENTS AND METHODS: This study included 92 metastatic chemotherapy-naive TGCT patients treated with platinum-based chemotherapy from July 2010 to March 2014. Plasma was isolated before first administration of chemotherapy, and the concentration of 51 plasma cytokines were analyzed using multiplex bead arrays...

INTRODUCTION: Intracranial teratomas are rare germ cell neoplasms that contain tissues derived from all three germ cell layers and most commonly occurring during childhood. This is the first report of pineal region mixed mature teratoma and germinoma in two fraternal brothers of fraternal triplets. CASE PRESENTATION: We report the case of a mixed mature teratoma and germinoma of the pineal region in two brothers of fraternal triplets. Older brother was initially diagnosed at the age of 11 years with the pure teratoma of the pineal region but the review of the pathology 3 years after initial surgery revealed the mixed mature teratoma with 5% germinomatous component...

Primary intracranial choriocarcinoma (PICCC), a type of germ-cell tumor, is a very rare primary tumor of the central nervous system that generally arises in the pineal or suprasellar region. We present a case of a teenage boy with PICCC of the bilateral basal ganglia, an anatomic site for which we were unable to find the previous reports. We offer discussion of the differential diagnosis, imaging characteristics, and prognosis of PICCC and germ-cell tumors of the basal ganglia, in the hope that it will increase awareness and allow for early detection...

PURPOSE OF REVIEW: We review current management strategies for patients with relapsed and refractory germ cell tumors (GCTs), defined as relapsed or persistent disease following at least one line of cisplatin-based chemotherapy. Additionally, we discuss future directions in the management of these patients. RECENT FINDINGS: Recent studies involving targeted therapies have been disappointing. Nevertheless, studies of the management of refractory germ cell cancer are ongoing, with a focus on optimal utilization of high-dose chemotherapy and autologous stem cell transplant, as well as the role of immune checkpoint inhibitors in refractory germ cell tumors...

Telomerase is expressed in more than 85% of cancer cells. Tumor cells with metastatic potential may have a high telomerase activity, allowing cells to escape from the inhibition of cell proliferation due to shortened telomeres. Human telomerase primarily consists of two main components: hTERT, a catalytic subunit, and hTR, an RNA template whose sequence is complimentary to the telomeric 5'-dTTAGGG-3' repeat. In humans, telomerase activity is typically restricted to renewing tissues, such as germ cells and stem cells, and is generally absent in normal cells...

Germ cell tumors and particularly seminomas reflect the epigenomic features of their parental primordial germ cells, including genomic DNA hypomethylation and expression of pluripotent cell markers. Because the DNA hypomethylation might be a result of TET dioxygenase activity, we examined expression of TET1-3 enzymes and the level of their product, 5-hydroxymethylcytosine, in a panel of histologically characterized seminomas and non-seminomatous germ cell tumors. Expression of TET dioxygenase mRNAs was quantified by real-time PCR...

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...

Cryptorchidism is the most common predisposing factor in the development of testicular germ cell tumors. Seminoma is the most common malignancy developing in a cryptorchid testis, usually has lymphatic but rarely hematogenous metastasis. The Urinary Bladder is an extremely rare site of metastasis of seminoma metastasis. A 29-year-old male patient presented to us with a history of infertility and an intra-abdominal mass. He was investigated and treated and was found to have an intra-abdominal seminoma with synchronous urinary bladder metastasis...

BACKGROUND: Pediatric germ cell tumors account for approximately 3.5 % of all childhood cancers for children under the age of 15 years. Up to one-third are extragonadal neoplasms. Germ cell tumors are a heterogeneous group of malignant tumors with a wide variety of histopathological features. Yolk sac tumor is the predominant variant in newborns and younger children. We report for the first time, the presentation of a primary yolk sac tumor in the abdominal wall of a small child. CASE PRESENTATION: An 18-month-old white girl underwent resection of a small, round subcutaneous lump (1...

BACKGROUND: The safety and efficacy of chemotherapy for patients undergoing concomitant hemodialysis have not been fully established and optimal doses of anti-cancer drugs and best timing of hemodialysis remains unclear. Although chemosensitive cancers, such as germ cell tumors, treated with chemotherapy should have sufficient dose intensity maintained to achieve the desired effect, many patients with cancer undergoing hemodialysis might be under-treated because the pharmacokinetics of anti-cancer drugs in such patients remains unknown...

Testicular germ cell cancer (TGCT) is the most common malignancy among young adult males, which has become important due to its increased incidence and mortality in the population worldwide. The etiology is multifactorial. Recent studies have shown some associations between the development of isolated TGCT and certain risk factors, such as exposure to endocrine disruptors, cryptorchidism, and family history of cancer, in order to identify the key pieces in carcinogenesis. Some of the most important findings in recent years is the association of different genes, such as c-KIT/KITLG, expression of the miR-371-373 cluster and protein expression as c-KIT and POU5F1 in the development of this neoplasia, and the identification of new molecular markers as TGFBR3 gene, identifying aberrant methylation patterns in promoter regions of several genes, expression of miR-1297 which regulates PTEN and protein expression as DMTR1...

RNA-binding proteins (RBPs) and miRNAs are capable of controlling processes in normal development and cancer. Both of them could determine RNA transcripts fate from synthesis to decay. One such RBP, Dead end (Dnd1), is essential for regulating germ-cell viability and suppresses the germ-cell tumors development, yet how it exerts its functions in breast cancer has remained unresolved. The level of Dnd1 was detected in 21 cancerous tissues paired with neighboring normal tissues by qRT-PCR. We further annotated TCGA (The Cancer Genome Atlas) mRNA expression profiles and found that the expression of Dnd1 and Bim is positively correlated (p = 0...

Adult mesenchymal stromal cell-based interventions have shown promising results in a broad range of diseases. However, their use has faced limited effectiveness owing to the low survival rates and susceptibility to environmental stress on transplantation. We describe the cellular and molecular characteristics of multilineage-differentiating stress-enduring (Muse) cells derived from adipose tissue (AT), a subpopulation of pluripotent stem cells isolated from human lipoaspirates. Muse-AT cells were efficiently obtained using a simple, fast, and affordable procedure, avoiding cell sorting and genetic manipulation methods...

Breast cancer being one of the common cancers has high morbidity and mortality. Despite the conventional treatment, the burden of the disease increases year after year. There is a need for newer drugs that target the different mechanisms in the pathogenesis. The interaction of cyclins with cyclin dependent kinases (CDKs) plays a major role in the abnormal cell cycle in cancer and it is considered to be an important target. Palbociclib is a CDK inhibitor currently approved for the treatment of breast cancer...
