PURPOSE: To examine the clinical presentation, treatment and results in children and adolescents with primary mediastinal (PM) and retroperitoneal (RP) germ cell tumors (GCTs). METHODS: The TGM95 trial for malignant GCTs was conducted in France between 1995 and 2005 to evaluate a strategy adapted to prognostic factors with cisplatin-based chemotherapy and surgical management. We reviewed patients with TGCTs at PM and RP sites. RESULTS: Among 239 patients, there were 16 patients with PM and 5 with RP tumors, which represent 9% of all patients, highlighting the rarity of these extragonadal locations...

Importance: Cancer occurs in 0.05% to 0.1% of all pregnancies. Despite literature reporting good oncologic and fetal outcomes in women treated for cancer during pregnancy, as many as 44% of gynecologists would offer termination, and 37% would not administer chemotherapy or radiotherapy in pregnancy. Objectives: The aims of this study were to summarize current recommendations for the treatment of cervical and ovarian cancers in pregnancy and to review updates on existing knowledge regarding the safety of surgical and chemotherapeutic treatments in pregnancy, including both oncologic and fetal outcomes...

Melanoma antigen (MAGE) genes are conserved in all eukaryotes and encode for proteins sharing a common MAGE homology domain. Although only a single MAGE gene exists in lower eukaryotes, the MAGE family rapidly expanded in eutherians and consists of more than 50 highly conserved genes in humans. A subset of MAGEs initially garnered interest as cancer biomarkers and immunotherapeutic targets due to their antigenic properties and unique expression pattern that is primary restricted to germ cells and aberrantly re-activated in various cancers...

Germ cell tumors (GCT) are a rare form of childhood cancer that originate from the primordial germ cell. Recent genome-wide association studies (GWAS) have identified susceptibility alleles for adult testicular GCT (TGCT). We test whether these SNPs are associated with GCT in pediatric and adolescent populations. This case-parent triad study includes individuals with GCT diagnosed between ages 0-19. We evaluated 26 SNPs from GWAS of adult TGCT and estimated main effects for pediatric GCT within complete trios (N=366) using the transmission disequilibrium test...

BACKGROUND: Childhood and adolescent cancers are uncommon, but they have important economic and health impacts on patients, families, and health care systems. Few studies have measured the economic burden of care for childhood and adolescent cancers. OBJECTIVES: To estimate costs of cancer care in population-based cohorts of children and adolescents from the public payer perspective. METHODS: We identified patients with cancer, aged 91 days to 19 years, diagnosed from 1995 to 2009 using cancer registry data, and matched each to three noncancer controls...

BACKGROUND: Pancreatic cancer has become the third leading cause of cancer death with minimal improvements in outcome for over 40 years. Recent trials of therapies that target-defective DNA maintenance using poly (ADP-ribose) polymerase (PARP) inhibitors are showing promising results, yet invariably patients recur and succumb to disease. Mechanisms of resistance to platinum-based and PARP inhibitor therapy in other cancer types include secondary mutations, which restore the integrity of DNA repair through an increasing number of different mechanisms...

Desmoids tumors, characterized by monoclonal proliferation of myofibroblasts, could occur in 5-10% of patients with familial adenomatous polyposis (FAP) as an extra-colonic manifestation of the disease. FAP can develop when there is a germ-line mutation in the adenomatous polyposis coli gene. Although mild or attenuated FAP may follow mutations in 5΄ extreme of the gene, it is more likely that 3΄ extreme mutations haveamore severe manifestation of thedisease. A 28-year-old woman was admitted to the Cancer Institute of Iran with an abdominal painful mass...

Biofilms, sedimented microbial communities embedded in a biopolymer matrix cause vast majority of human bacterial infections and many severe complications such as chronic inflammatory diseases and cancer. Biofilms' resistance to the host immunity and antibiotics makes this kind of infection particularly intractable. Antimicrobial peptides (AMPs) are a ubiquitous facet of innate immunity in animals. However, AMPs activity was studied mainly on planktonic bacteria and little is known about their effects on biofilms...

Studies have suggested mosaic loss of chromosome Y (mLOY) in blood-derived DNA is common in older men. Cohort studies investigating mLOY and mortality have reported contradictory results. Previous work found that a 1.6 Mb deletion of the AZFc region on the Y chromosome (the 'gr/gr' deletion) is associated with both male infertility and increased risk of testicular germ cell tumors (TGCT). We investigated whether mosaic loss across the entire Y chromosome was associated with TGCT. We obtained blood- and buccal-derived DNA from two case-control studies: the NCI Familial Testicular Cancer Study (cases=172; controls=163) and the NCI US Servicemen's Testicular Tumor Environmental and Endocrine Determinants Study (cases=506; controls=611)...

OBJECTIVE: We investigated the prognostic value of preoperative neutrophil-to-lymphocyte ratio (NLR) on germ cell testicular tumors (GCT). MATERIAL AND METHODS: The data of 53 patients who underwent inguinal orchiectomy were analyzed retrospectively. NLR was calculated from the preoperative complete blood cell counts. Receiver operating characteristic (ROC) analysis was performed to find the threshold values for NLR. Correlations between cancer-specific survival (CSS) and progression-free survival (PFS) and NLR were evaluated...

Cisplatin and its platinum analogs, carboplatin and oxaliplatin, are some of the most widely used cancer chemotherapeutics. Although cisplatin and carboplatin are used primarily in germ cell, breast and lung malignancies, oxaliplatin is instead used almost exclusively to treat colorectal and other gastrointestinal cancers. Here we utilize a unique, multi-platform genetic approach to study the mechanism of action of these clinically established platinum anti-cancer agents, as well as more recently developed cisplatin analogs...

INTRODUCTION: Treatment options for patients with platinum refractory metastatic germ cell tumours (GCT) relapsing after high-dose chemotherapy and autologous stem cell transplantation are limited and survival is poor. Antibodies directed against programmed cell death protein-1 (PD-1) and programmed cell death ligand-1 (PD-L1) are currently assessed within clinical trials. We present updated data on our experience with checkpoint inhibitors as a compassionate use off-label treatment attempt for highly-pretreated patients with GCT and provide an overview of the current literature on PD-L1 expression in this rare tumour entity...

Germ cell tumors (GCTs) are one of the more curable solid cancers in men. Approximately 8500 men are diagnosed with GCTs in the USA. The majority of patients survive due to the availability of effective treatment. Fewer than 400 men are estimated to die from their disease. Among those, there is a subset of patients with metastatic GCTs receiving chemotherapy who rapidly develop progressive respiratory failure and die during the early phase of their treatment course. In this review, we searched the available literature for reported cases and retrospective series of chemotherapy-associated acute respiratory distress syndrome in GCTs...

BACKGROUND: Principal Treatment Centres (PTC) were established to provide age-appropriate care as well as clinical expertise for children and young people with cancer. However, little is known about the effects of specialist treatment centres on survival outcomes especially for teenagers and young adults. This population-based study aimed to describe access to PTC and the associated trends in survival for 0-24 year olds accounting for stage of disease at presentation and treatment. METHODS: Patients diagnosed from 1998-2009 aged 0-24 years were extracted from the Yorkshire Specialist Register of Cancer in Children and Young People, including information on all treating hospitals, followed-up until 31st December 2014...

So far, the understanding of germ cell cancer (GCC) pathogenesis is based on a model, where seminomas and non-seminomas represent distinct entities although originating from a common precursor termed germ cell neoplasia in situ (GCNIS). Embryonal carcinomas (ECs), the stem cell population of the non-seminomas, is pluri- to totipotent and able to differentiate into cells of all three germ layers, giving rise to teratomas or tumours mimicking extraembryonic tissues (yolk sac tumours, choriocarcinomas). With regard to gene expression, (epi)genetics and histology, seminomas are highly similar to GCNIS and primordial germ cells, but limited in development...

BACKGROUND: Testicular germ cell tumors (TGCTs) are rare tumors in the general population but are the most commonly occurring malignancy among males between ages 15 and 44 years in the United States (US). Although non-Hispanic whites (NHWs) have the highest incidence in the US, rates among Hispanics have increased the most in recent years. To forecast what these incidence rates may be in the future, an analysis of TGCT incidence in the Surveillance, Epidemiology, and End Results program and the National Program of Cancer Registries was conducted...

In the management of bladder cancer, surgical resection of the tumour is usually followed by intravesical instillation of immunomodulatives and/or chemotherapeutics. The purpose of this local intravesical therapy is to eliminate residual malignant cells after surgical intervention. The main limitation of a localised adjuvant therapy is the insufficient concentration of the active pharmaceutical ingredient (API) in malignant cells due to the unique structure of the human urothelium making it an exclusively hard to overcome barrier in the human body...
