Background: Cisplatin-based chemotherapy significantly improved the survival of patients with germ cell testicular cancer. However, long term side effects of chemotherapy have non-negligible impact on the quality of life of these young patients, who have a long life expectancy after being successfully treated. Materials and Methods: 25-OH vitamin D, testosterone, FSH and LH of patients with testicular cancer were retrospectively evaluated and for each patient clinical information were collected...

OBJECTIVES: To identify differentially expressed genes between relapsed (R) and non-relapsed (NR) clinical stage I (CSI) testicular germ cell tumor (TGCT). MATERIALS AND METHODS: We reviewed patients with CSI non-seminoma(NS) and seminoma(S) from an institutional database (2000-2012) managed by active surveillance. NR-NS and NR-S patients were defined as being relapse free after 2 and 3 years of surveillance respectively. RNA extraction and gene expression analysis was performed on archival primary tumor samples and Gene-Set-Enrichment-Analysis (GSEA) was conducted in order to identify differentiating biological pathways...

INTRODUCTION AND AIM: Survival of germ cell testicular cancer (TC) patients is better than for other malignancies and has not yet been exactly studied in the Slovak Republic. The aim of the study, based on the analyses of epidemiological data over time, was to present 5-year survival trends for germ cell TC patients. PATIENTS AND METHODS: Survival is assessed within the framework of a nation-wide retroprospective study among TC patients newly diagnosed between 1993-2007 (divided to three 5-year periods according the time of diagnosis - 1993-1997, 1998-2002 and 2003-2007)...

Bleomycin pulmonary toxicity (BPT) has been well described in patients with germ cell tumors treated with bleomycin etoposide and cisplatin chemotherapy (BEP). To assess the prognostic impact of BPT, we retrospectively identified 52 patients who underwent bleomycin etoposide and cisplatin chemotherapy from 2008 to 2017 in our institution, and evaluated the risk factors of BPT and its effect on prognosis. Patients who had received chemotherapy at another institution were excluded. BPT was defined as bleomycin discontinuation in response to pulmonary function test decline, pulmonary symptoms, or interstitial pneumonia on computed tomography without infection...

Testicular germ cell tumors (TGCTs) are classified into two main subtypes, seminoma (SE) and non-seminoma (NSE), but their molecular distinctions remain largely unexplored. Here, we used expression data for mRNAs and microRNAs (miRNAs) from The Cancer Genome Atlas (TCGA) to perform a systematic investigation to explain the different telomere length (TL) features between NSE (n = 48) and SE (n = 55). We found that TL elongation was dominant in NSE, whereas TL shortening prevailed in SE. We further showed that both mRNA and miRNA expression profiles could clearly distinguish these two subtypes...

INTRODUCTION: Testicular cancer is the most common type of cancer in young Caucasian men. It has been suggested that testicular microlithiasis (TML) is a premalignant condition. This study's objective was to investigate TML histology prevalence in testicular cancer patients in two European populations. METHODS: We analysed archived histopathology orchiectomy specimens from 152 patients diagnosed with testicular cancer at Fredericia Hospital in Denmark from 2004 to 2014, and 106 patients diagnosed at St Thomas' Hospital in London from 2011 to 2015...

Germ cell tumors (GCT) are malignant tumors that arise from pluripotent embryonic germ cells and occur in children and young adults. GCTs are treated with cisplatin-based regimens which, while overall effective, fail to cure all patients and cause significant adverse late effects. The seminoma and nonseminoma forms of GCT exhibit distinct differentiation states, clinical behavior, and response to treatment; however, the molecular mechanisms of GCT differentiation are not fully understood. We tested whether the activity of the mTORC1 and MAPK pathways were differentially active in the two classes of GCT...

PURPOSE: Retroperitoneal lymph node dissection is recommended for residual masses greater than 1 cm after chemotherapy of nonseminomatous germ cell tumors. Currently to our knowledge there is no reliable predictor of post-chemotherapy retroperitoneal lymph node dissection histology. Up to 50% of patients harbor necrosis/fibrosis only so that a potentially morbid surgery has limited therapeutic value. In this study we evaluated the ability of defined serum miRNAs to predict residual viable nonseminomatous germ cell tumors after chemotherapy...

The development of the human gonads is tightly regulated by the correct sequential expression of many genes and hormonal activity. Disturbance of this regulation does not only prevent proper development of the gonads, but it also contributes to the development of testicular germ cell tumors. Recent genetic studies, especially genome-wide association studies, have made great progress in understanding genetic susceptibility. Although there is strong evidence of inherited risks, many environmental factors also contribute to the development of testicular germ cell tumors...

A late-relapse germ cell tumor might contain malignant non-germ cell tumors, known as 'somatic-type malignancy (SM)'. The development of a secondary SM is rare, and this phenomenon remains poorly understood. Case 1 developed lung metastasis 13 years after chemotherapy followed by retroperitoneal lymph node dissection for stage IIA non-seminoma. The tumor increased in size after chemotherapy. The patient underwent a pneumonectomy. Pathology revealed an adenocarcinoma with immature teratoma. The patient has experienced no relapse for 9 years...

Testicular germ cell tumours (GCT) represent about 1-2% of malignant in men. The essential therapeutic option for early-stage GCT is radical orchiectomy (RO), except in situations that require immediate chemotherapy in patients with a massive dissemination and unequivocally elevated levels of tumour markers. Postoperative radiotherapy (PORT) in patients with testicular seminoma in Clinical Stage I (CS I) is one of the treatment options next to active surveillance (AS) and chemotherapy (CHTH). Regardless of the procedure, five-year survival in this group of patients ranges between 97% and 100%...

Testicular germ cell tumours (TGCTs) are the most frequent malignancy and cause of death from solid tumours in the 20- to 40-year age group. Although most cases show sensitivity to cis-platinum-based chemotherapy, this is associated with long-term toxicities and chemo-resistance. Roles for receptor tyrosine kinases other than KIT are largely unknown in TGCT. We therefore conducted a phosphoproteomic screen and identified the insulin growth factor receptor-1 (IGF1R) as both highly expressed and activated in TGCT cell lines representing the nonseminomatous subtype...

IMP3 is an RNA binding protein required for ribosomal RNA processing, which has been suggested to be a prognostic marker in a large variety of human types of cancer. However, available data on the prevalence of IMP3 expression are largely discrepant. To systematically investigate the epidemiology and clinical relevance of IMP3 expression in human cancers we employed a two-step tissue microarrays (TMAs) approach. First, a normal tissue TMA and a multi-tumor TMA were analyzed for immunohistochemically detectable expression of IMP3 in 76 different normal tissue types and 3889 cancer samples from 95 different tumor categories...

OBJECTIVES: The aim of our study was to evaluate associations of elevated preoperative neutrophil-to-lymphocyte ratio (NLR) with testicular germ cell tumors (GCT) characteristics other than cancer specific survival (CSS) and progression free survival (PFS). BACKGROUND: NLR was recently presented as a widely available and inexpensive marker of poor prognosis in several types of solid tumors. Previous study showed no predictive value of NLR for CSS and PFS in testicular GCT...

BACKGROUND: Testicular germ cell tumor (TGCT) is the most common solid malignancy occurring in young men between 20 and 34 years of age, and its incidence has increased significantly over the last decades. TGCTs can be subdivided into seminoma and nonseminoma germ cell tumors (NSGCTs), which includes yolk sac tumor, choriocarcinoma, embryonal cell carcinoma, and teratoma. Seminomas and NSGCTs present significant differences in therapy, prognosis, and both show characteristics of the Primordial Germ Cells (PGCs)...
