BACKGROUND: Childhood cancer survivors can experience learning problems resulting in lower-than-expected attained education as adults. It is unclear whether learning problems manifest already during adolescence. METHODS: We analysed nationwide Danish registries on school grades for Danish children during 2001-2014. Applying a matched design we compared grades of childhood cancer survivors to children without cancer at ninth grade. We estimated grade differences by subject and its correlation to cancer site and age at diagnosis...

Expression profiling and genomic sequencing methods enable the accumulation of vast quantities of data that relate to expression of genes during the maturation of male germ cells from primordial germ cells to spermatozoa, and potential mutations that underlie male infertility. However, determination of gene function in specific aspects of spermatogenesis or linking abnormal gene function with infertility remain rate limiting, as even in an era of CRISPR analysis of gene function in mammalian models, this still requires considerable resources and time...

OBJECTIVE: The mediastinum is the central portion of the thoracic cavity, housing numerous organs and harbouring a mixed bag of non-neoplastic and neoplastic lesions. Accurate diagnosis is essential owing to the widely variable therapeutic and prognostic implications. MATERIAL AND METHOD: Cases of mediastinal masses were retrospectively reviewed from January 2011 till January 2016. Clinico-radiological records of these cases were retrieved. Fine needle aspiration cytology (FNAC) was performed wherever feasible...

BACKGROUND: Data are lacking regarding the perception of cancer patients' prognosis by physicians who are not oncologists. METHODS: This was a multicenter survey of seven university-affiliated hospitals, assessing physicians' perception of the median survival of patients with seven advanced malignancies. The study cohort included physicians from all 73 internal medicine, surgery, emergency medicine and critical care departments in the participating hospitals. Family practitioners were contacted through email...

Teratomas are primary germ-cell tumours in the mediastinum. Although they are generally slow-growing and asymptomatic, rapid growth causing life-threatening complications can occur. Sebaceous secretion, insulin production, chorionic gonadotropin secretion and pancreatic enzyme secretion are the presumptive causes of tumour progression. Only few cases of rapidly growing teratomas have been reported previously. Here, we present a case of a giant mature teratoma in the mediastinum that presented with rapid growth and compare the characteristics of this case with those of previous cases...

Type II testicular germ cell cancers (TGCT) are the most frequently diagnosed tumours in young men (20-40 years) and are classified as seminoma or non-seminoma. TGCTs are commonly treated by orchiectomy and chemo- or radiotherapy. However, a subset of metastatic non-seminomas (embryonal carcinomas) displays only incomplete remission or relapse and requires novel treatment options. Recent studies have shown effective application of the small-molecule inhibitor JQ1 in tumour therapy, which interferes with the function of 'bromodomain and extraterminal (BET)' proteins...

The amniotic fluid has been identified as an untapped source of cells with broad potential, which possess immunomodulatory properties and don't have the ethical and legal limitations of embryonic stem cells. CD117(c-Kit)+ cells selected from amniotic fluid have been shown to differentiate into cell lineages representing all three embryonic germ layers without generating tumours, making them ideal candidates for regenerative medicine applications. Moreover, their ability to engraft in injured organs and modulate immune and repair responses of host tissues, suggest that transplantation of such cells may be useful for the treatment of various degenerative and inflammatory diseases...

Testicular germ cell tumour (TGCT) is the most common cancer in young men. Here we sought to identify risk factors for TGCT by performing whole-exome sequencing on 328 TGCT cases from 153 families, 634 sporadic TGCT cases and 1,644 controls. We search for genes that are recurrently affected by rare variants (minor allele frequency <0.01) with potentially damaging effects and evidence of segregation in families. A total of 8.7% of TGCT families carry rare disruptive mutations in the cilia-microtubule genes (CMG) as compared with 0...

This manuscript reports the consensus statements on designing clinical trials in rare ovarian tumours reached at the 5th Ovarian Cancer Consensus Conference (OCCC) held in Tokyo, November 2015. Three important questions were identified concerning rare ovarian tumours (rare epithelial ovarian cancers (eOC), sex-cord stromal tumours (SCST) and germ cell tumours (GCT)): (1) What are the research and trial issues that are unique to rare ovarian tumours? There is a lack of randomised phase III data defining standards of care which makes it difficult to define control arms, but identifies unmet needs that merit investigation...

Advances in modern chemotherapy and targeted treatments have resulted in lengthened survival in a variety of tumour types in the last decade. Increasingly in the 21st century, postchemotherapy resections are considered as a possible mode of treatment. Due to their exquisite chemosensitivity, resection of postchemotherapy masses has long been part of the armamentarium of treatment in testicular germ cell neoplasia, which has resulted in a variety of new morphological variants being described after treatment...

BACKGROUND: Pseudomyxoma peritonei (PMP) is a rare disease with an estimated incidence of 1-2 cases per million individuals per year. PMP is characterized by the accumulation of abundant mucinous or gelatinous fluid derived from disseminated tumorous cells. Most of the tumorous cells are originated from rupture of appendiceal neoplasms, but some are from the metastasis of cancer of the colon, ovary, fallopian tube, urachus, colorectum, gallbladder, stomach, pancreas, lung and breast. Although frequent mutations in KRAS and/or GNAS genes have been reported, precise molecular mechanism underlying PMP remains to be elucidated...

OBJECTIVE: Ovarian cancers comprise several histologically distinct tumour groups with widely different prognosis. We aimed to describe the worldwide distribution of ovarian cancer histology and to understand what role this may play in international variation in survival. METHODS: The CONCORD programme is the largest population-based study of global trends in cancer survival. Data on 681,759 women diagnosed during 1995-2009 with cancer of the ovary, fallopian tube, peritoneum and retroperitonum in 51 countries were included...

Glioblastoma multiforme (GBM) is extremely rare in the pineal region, with only 19 previously reported cases. We report a unique case of a teenage girl with a pineal tumour with markedly raised beta-human chorionic gonadotropin (BHCG) levels, thought to be a germ-cell tumour. However, the raised BHCG was due to pregnancy, and biopsy revealed a pineal GBM.

OBJECTIVE: Ovarian cancer comprises several histological groups with widely differing levels of survival. We aimed to explore international variation in survival for each group to help interpret international differences in survival from all ovarian cancers combined. We also examined differences in stage-specific survival. METHODS: The CONCORD programme is the largest population-based study of global trends in cancer survival, including data from 60 countries for 695,932 women (aged 15-99years) diagnosed with ovarian cancer during 1995-2009...

Germ-cell tumours (GCTs) are derived from germ cells and occur most frequently in the testes. GCTs are histologically heterogeneous and distinctly curable with chemotherapy. Gains of chromosome arm 12p and aneuploidy are nearly universal in GCTs, but specific somatic genomic features driving tumour initiation, chemosensitivity and progression are incompletely characterized. Here, using clinical whole-exome and transcriptome sequencing of precursor, primary (testicular and mediastinal) and chemoresistant metastatic human GCTs, we show that the primary somatic feature of GCTs is highly recurrent chromosome arm level amplifications and reciprocal deletions (reciprocal loss of heterozygosity), variations that are significantly enriched in GCTs compared to 19 other cancer types...

Germ Cell Tumours (GCTs) are rare tumours. Generally 80% are benign and 20% malignant with a bimodal age distribution. The retrospective study was conducted at Shaukat Khanum Cancer Hospital, Lahore, Pakistan, and comprised all paediatric patients below 18 years of age who received treatment for histology-proven GCT from 2006 to 2014. Of the 207 patients, 98(42.3%) were males and 109(52.7%) were females. The most common GCT was yolk sac tumour in 90(43.5%) children followed by mixed GCT in 40(19.3%) and dysgerminoma in 34(16...

Anthracyclines such as doxorubicin (Dox), widely used to treat various types of tumours, may result in induced testicular toxicity and oxidative stress. The present investigation was designed to determine whether exposure of isolated and purified mouse germ cells to Dox induces DNA damage in the form of strand breaks (presumably) resulting in apoptosis and to investigate the relative sensitivity of specific cell types. DNA damage was assessed using the Comet assay and the presence of apoptosis was determined by TUNEL assay...

Seminomatous germ cell tumours characteristically affect men in their second-to-fourth decades, presenting as a testicular mass. Metastases when present are usually seen in para-aortic lymph nodes. These tumours are difficult to diagnose clinically and histologically when the presentation is unusual. We describe a seminoma presenting in a 61-year-old male as an inguinal mass with associated lymphadenopathy resembling lymphoma. Past medical history included ipsilateral cryptorchidism and orchidopexy. The tumour responded well to conventional chemotherapy...

Testicular germ cell tumours of young adults are comprised of a heterogeneous group of non-seminomas and a homogeneous group of seminomas. While the majority of seminomas retain a hypo-methylated genome, a small fraction displays a highly methylated genome, resembling hyper-methylated non-seminomas. It is well established from e.g. melanoma, colorectal and thyroid cancer that a methylated phenotype can be correlated to prognosis and can be related to BRAF mutations. In the present study we investigated the global methylation level in 67 seminomas and classified them as hypo-methylated, intermediate, patchy and hyper-methylated, respectively...

Ovarian cancer is the fifth cause of cancer-related death in women and comprises a histologically and genetically broad range of tumours, including those of epithelial, sex cord-stromal and germ cell origin. Recent evidence indicates that high-grade serous ovarian carcinoma, clear cell carcinoma and endometrioid carcinoma primarily arise from tissues that are not normally present in the ovary. These histogenetic pathways are informing risk-reduction strategies for the prevention of ovarian and ovary-associated cancers and have highlighted the importance of the seemingly unique ovarian microenvironment...
