BACKGROUND: Several maternal and birth characteristics have been reported to be associated with an increased risk of many childhood cancers. Our goal was to evaluate the risk of childhood embryonal solid tumors in relation to pre- and perinatal characteristics. METHODS: A case-cohort study was performed using two population-based datasets, which were linked through R software. Tumors were classified as central nervous system (CNS) or non-CNS-embryonal (retinoblastoma, neuroblastoma, renal tumors, germ cell tumors, hepatoblastoma and soft tissue sarcoma)...

We reported two cases of hyperthyroidism that developed during induction chemotherapy for advanced germ cell tumors with high serum human chorionic gonadotropin (hCG) levels. Case 1 : An 18-year-old man with mediastinal choriocarcinoma complained of tachycardia and tremor. His pretreatment serum hCG level was 1.37 million mIU/ml. The free thyroxine (fT4) level measured on day 2 of the first course of bleomycin, etoposide and cisplatin (BEP) was elevated to 7.8 ng/dl (<1.7 ng/dl), whereasthe thyroidstimulating hormone (TSH) level was undetectable...

A 37-year-old man presented at our hospital. Pathological examination of a right orchiectomy specimen, radiographic examination, and tumor marker profile resulted in a diagnosis of retroperitoneal nonseminomatous germ cell tumor (intermediate risk according to IGCC classification). Laboratory testing revealed mild elevation of low density lipoprotein cholesterol. Induction chemotherapy with bleomycin, etoposide and cisplatin (BEP) was started, but he complained of chest pain on day 10 of the second cycle of BEP...

INTRODUCTION: Polymethylmethacrylate (PMMA) cement is useful for spinal reconstruction, but can cause complications including new vertebral fractures, neurological disorders and pulmonary embolism. We report a case in PMMA cement used for spinal reconstruction after tumor curettage dislodged and penetrated the gastrointestinal tract. DIAGNOSES: The patient was diagnosed with a retroperitoneal extragonadal germ cell tumor at age 27 years. After chemotherapy and tumor resection, the tumor remained...

Development of cancer vaccines targeting tumor-associated antigens (TAAs) is an alternative approach to chemotherapy with sustained anti-tumor effects. The success of active immunotherapy has been hampered by tumor-induced immune suppressors. Regulatory T cells (Tregs) are a population of immune suppressors with a proven role in regulating anti-tumor immune responses. Removing or subduing Tregs activity leads to more robust anti-tumor immune responses. Here, we used a cell-based vaccination strategy in the 4T1 murine mammary model to examine whether bulk removal of certain TAAs, using their glycan profile, can affect the immunogenicity of the vaccine...

BACKGROUND: While ovarian mature cystic teratomas are benign ovarian germ-cell tumors and the most common type of all ovarian tumors, the formation of fistulas into surrounding organs such as the bladder and the intestinal tract is extremely rare. This report documents a case of ovarian mature cystic teratoma with a rectal fistula, thought to be caused by local inflammation. CASE DESCRIPTION: A pelvic mass was diagnosed as an ovarian mature cystic teratoma of approximately 10 cm in diameter on transvaginal ultrasound and magnetic resonance examinations...

Tripartite motif 44 (TRIM44) is one of the TRIM family proteins that are involved in ubiquitination and degradation of target proteins by modulating E3 ubiquitin ligases. TRIM44 overexpression has been observed in various cancers. However, its association with testicular germ cell tumor (TGCT) is unknown. We aimed to investigate the clinical significance of TRIM44 and its function in TGCT. High expression of TRIM44 was significantly associated with alpha feto-protein levels, clinical stage, nonseminomatous germ cell tumor (NSGCT), and cancer-specific survival (P = 0...

Salvage high-dose chemotherapy (HDC) and autologous hematopoietic stem cell (HSC) transplantation represents a curative treatment option for patients with relapsed/refractory germ-cell tumors (GCTs). However, an appreciable proportion of these fail to mobilize adequate numbers of hematopoietic progenitors; thus, plerixafor is applied for that purpose. Limited data exist on remobilization of HSCs after previous autografting. Here, we report a unique case that had undergone successful previous tandem HDC for relapsed GCT, and 1 year later required remobilization of HSCs to support two further cycles of HDC after subsequent multiple relapses and refractoriness requiring various salvage regimens...

BACKGROUND: Primary treatment of choice for advanced germ cell tumors is 3 to 4 cycles of combination PEB chemotherapy. Although most patients treated for advanced germ cell tumors (GCT) will be cured, approximately 30% will fail to achieve a durable complete response (CR). Thrombocytosis has been found to be related with significantly shorter survival in many cancers. However, its role in testicular cancer patients has not been studied previously. The objective of this study was to investigate the relationship between thrombocytosis and chemotherapy response in patients with metastatic testicular cancer...

Germ cell tumors (GCTs) are extraordinarily sensitive to cisplatin (CDDP)-based chemotherapy. DNA damage represents one of the most important factors contributing to toxic effects of CDDP-based chemotherapy. This study was aimed to evaluate the prognostic value of DNA damage level in peripheral blood lymphocytes (PBLs) from chemo-naïve GCT patients. PBLs isolated from 59 chemotherapy-naïve GCT patients were included into this prospective study. DNA damage levels in PBLs were evaluated by the Comet assay and scored as percentage tail DNA by the Metafer-MetaCyte analyzing software...

Due to its palindromic setup, AZFc (Azoospermia Factor c) region of chromosome Y is one of the most unstable regions of the human genome. It contains eight gene families expressed mainly in the testes. Several types of rearrangement resulting in changes in the cumulative copy number of the gene families were reported to be associated with diseases such as male infertility and testicular germ cell tumors. The best studied AZFc rearrangement is gr/gr deletion. Its carriers show widespread phenotypic variation from azoospermia to normospermia...

Between September 1995 and December 2010, 99 new consecutive assessable patients with extra-cranial MGCT were treated according to SFOP/SFCE TGM95 Protocol. A "watch and wait" strategy for completely resected stage I-II was observed in cases with preoperative high tumor markers levels. Metastatic disease or alpha fetoprotein levels > 15 000 ng/ml cases were treated by VIP chemotherapy (etoposide, ifosfamide and CDDP) 4-6-courses. All other cases were treated by VBP (vinblastine, bleomycin, and CDDP) 3-5 courses...

PURPOSE: Fibrosis accounts for approximately 50% of histological findings at post-chemotherapy retroperitoneal lymph node dissection (PC-RPLND), and is associated with reported relapse rates of 10%-15%. We aimed to characterize patients with fibrosis at PC-RPLND, and identify predictors of adverse outcome within this group. MATERIALS AND METHODS: We reviewed the medical records of men who underwent PC-RPLND between 1989-2013 with histological findings of necrosis/fibrosis...

Development of a malignant germ cell tumor, i.e., germ cell cancer (GCC) in individuals with disorders of sex development (DSD) depends on a number of (epi-)genetic factors related to early gonadal- and germ cell development, possibly related to genetic susceptibility. Fetal development of germ cells is orchestrated by strict processes involving specification, migration and the development of a proper gonadal niche. In this review we will discuss the early (epi-)genetic events in normal and aberrant germ cell and gonadal development...

PURPOSE: Rare cancers represent 22% of all tumors in Europe; however, the quality of the data of rare cancers may not be as good as the quality of data for common cancer. The project surveillance of rare cancers in Europe (RARECARE) had, among others, the objective of assessing rare cancer data quality in population-based cancer registries (CRs). Eight rare cancers were considered: mesothelioma, liver angiosarcoma, sarcomas, tumors of oral cavity, CNS tumors, germ cell tumors, leukemia, and malignant digestive endocrine tumors...

BACKGROUND: Fine-needle aspiration (FNA) biopsy of lung lesions is a highly accurate method for diagnosing and staging of lung cancers, particularly in patients with advanced cancer. Although, the majority of FNA cases of non-small cell lung carcinoma (NSCLC) can be subclassified by hematoxylin and eosin (H&E) sections, immunohistochemical (IHC) markers are usually necessary for difficult cases. Our previous study has shown that both P40 and P63 demonstrate differential sensitivity and specificity in the subclassification of squamous cell carcinoma (SqCC) using tumor tissue microarrays (TMA)...
