Authors:
Ruili Li Hongjun Li

BMC Cancer 2019 Mar 18;19(1):244. Epub 2019 Mar 18.

Department of Radiology, Beijing Youan Hospital, Capital Medical University, No. 8, Xi Tou Tiao, Youanmen Wai, Fengtai District, Beijing, 100069, China.

Background: Nonseminomatous germ cell tumors (NSGCTs) represent one of the main groups of germ cell tumors (GCTs), and they have a more invasive course than seminomatous GCTs. Human immunodeficiency virus (HIV) positivity is considered to be a risk factor for testicular seminoma patients, but reports about HIV-infected individuals with NSGCTs are rare.

Case Presentation: We report a case of a retroperitoneal mixed extragonadal germ cell tumor in an HIV-infected man who has been diagnosed with bilateral cryptorchidism since birth. Read More

Genomic Features for Therapeutic Insights of Chemotherapy-Resistant, Primary Mediastinal Nonseminomatous Germ Cell Tumors and Comparison with Gonadal Counterpart.

Oncologist 2019 Apr 18;24(4):e142-e145. Epub 2019 Jan 18.

Upstate Medical University, Syracuse, New York, USA.

Primary mediastinal nonseminomatous germ cell tumors (PMNSGCT) frequently become refractory to chemotherapy, and no effective salvage therapy exists. We performed genomic profiling on a series of 44 PMNSGCT and compared the results with those from chemorefractory, metastatic pure seminomatous (Sem, = 22) and nonseminomatous (NS, = 86) testicular germ cell tumors. Archival tissues were sequenced by a hybrid capture-based technology (FoundationONE; Foundation Medicine, Inc. Read More

Growing teratoma syndrome in primary mediastinal germ cell tumor: our experience.

Asian Cardiovasc Thorac Ann 2019 Feb 15;27(2):98-104. Epub 2019 Jan 15.

5 Department of Cardiovascular and Thoracic Surgery, Jawaharlal Institute of Postgraduate Medical Education & Research, Pondicherry, India.

Background: Growing teratoma syndrome is a rare phenomenon seen in nonseminomatous germ cell tumors after chemotherapy, where the tumor grows paradoxically despite normalization of tumor markers. It has been found in various locations, most commonly, the retroperitoneum in association with metastatic disease. The occurrence of growing teratoma syndrome in a mediastinal primary is very rare and there are only a few reports in the literature. Read More

5-Azacitidine Exerts Prolonged Pro-Apoptotic Effects and Overcomes Cisplatin-Resistance in Non-Seminomatous Germ Cell Tumor Cells.

Int J Mol Sci 2018 Dec 21;20(1). Epub 2018 Dec 21.

Department of Oncology, Hematology and Bone Marrow Transplantation with Division of Pneumology, University Medical Center Eppendorf, 20246 Hamburg, Germany.

Despite high cure rates, about 20% of patients with advanced germ cell tumors (GCTs) fail cisplatin-based chemotherapy. High levels of DNA methylation have been identified in GCTs and linked to cisplatin resistance. Here, we examined the effects of DNA hypomethylating 5-azacitidine (5-aza) on two embryonal carcinoma cell lines (NCCIT, 2102Ep) and their cisplatin-resistant isogenic derivatives. Read More

Serum tumor markers and testicular germ cell tumors: a primer for radiologists.

Abdom Radiol (NY) 2019 Mar;44(3):1083-1090

University Hospitals Cleveland Medical Center, 11100 Euclid Ave, Cleveland, OH, 44106, USA.

Serum tumor markers (STMs) play a critical role in the diagnosis, staging and follow-up of both seminomatous and nonseminomatous testicular germ cell neoplasms. Levels of alpha-fetoprotein (AFP), human chorionic gonadotropin (HCG), and lactate dehydrogenase (LDH), especially those measured after orchiectomy, also have implications for patient prognosis. Given that testicular germ cell tumors represent the most common solid tumor in men aged 20-34, radiologists must have familiarity with the clinical utilization and implications of these STMs. Read More

Choriocarcinoma Syndrome as an Initial Presentation of Testicular Cancer.

Case Rep Oncol Med 2018 8;2018:8065615. Epub 2018 Nov 8.

Centro Universitario Contra el Cáncer, University Hospital "Dr. José Eleuterio González" and Faculty of Medicine, Universidad Autónoma de Nuevo León, Monterrey, Nuevo León, Mexico.

Choriocarcinoma syndrome (CS) is a rare clinical entity within the spectrum of nonseminomatous germ-cell tumors (NSGCT). It is characterized by the abrupt establishment of rapidly progressive and hemorrhagic tumors associated with very high levels of the beta fraction of human chorionic gonadotropin (-hCG) and with a very poor prognosis, particularly in patients with -hCG values above 50,000 IU/L. We present the case of a 17-year-old man with a sudden onset nonmassive hemoptysis. Read More

Is there still a place for retroperitoneal lymph node dissection in clinical stage 1 nonseminomatous testicular germ-cell tumours? A retrospective clinical study.

BMC Urol 2018 Oct 26;18(1):95. Epub 2018 Oct 26.

MVZ Hanse Histologikum, Hamburg, Germany.

Background: Primary retroperitoneal lymph node dissection (RPLND) ultimately lost its role as the standard management of clinical stage (CS) 1 nonseminomatous (NS) testicular germ cell tumours (GCTs) in Europe when the European Germ Cell Cancer Consensus Group released their recommendations in 2008. Current guide-lines recommend surgery only for selected patients but reasons for selection remain rather ill-defined. We evaluated the practice patterns of the management of CS1 patients and looked specifically to the role of RPLND among other standard treatment options. Read More

Seminoma component of mixed testicular germ cell tumor shows a higher incidence of loss of heterozygosity than pure-type seminoma.

Hum Pathol 2019 Feb 25;84:71-80. Epub 2018 Sep 25.

Department of Basic Pathology, National Defense Medical College, Tokorozawa, Saitama 359-8513, Japan.

Using analysis of allelic loss (loss of heterozygosity [LOH]), we previously reported a putative progression pathway from germ cell neoplasia in situ (GCNIS) to seminoma and then to embryonal carcinoma in mixed-type testicular germ cell tumors. To identify the genetic backgrounds related to the progression of nonseminomatous germ cell tumor, patterns of LOH were studied in seminoma components in mixed tumors (18 cases), pure seminomas (20 cases), and coexisting GCNIS lesions. Each tumor was assessed for LOH at 22 polymorphic loci located on 12 chromosomal arms: 3q, 5q, 6p, 9p, 10q, 11p, 12p, 12q, 13q, 17p, 17q, and 18q. Read More

Nodule Size After Chemotherapy and Primary-Tumor Teratoma Components Predict Malignancy of Residual Pulmonary Nodules in Metastatic Nonseminomatous Germ Cell Tumor.

Ann Surg Oncol 2018 Nov 6;25(12):3668-3675. Epub 2018 Sep 6.

Urology Division, National Cancer Center Hospital, Tokyo, Japan.

Background: The treatment goal for visceral metastatic nonseminomatous germ cell tumor (NSGCT) is to remove any residual teratoma or viable NSGCT after chemotherapy. However, this provides no therapeutic benefit to patients whose metastases necrotize on their own. This study therefore analyzed NSGCTs with pulmonary metastases to determine preoperative factors that predict necrosis and could help identify patients who might be treated with monitoring rather than surgery.

Adjuvant Therapy for Stage IB Germ Cell Tumors: One versus Two Cycles of BEP.

Adv Urol 2018 2;2018:8781698. Epub 2018 Apr 2.

Institute of Cancer Research and Royal Marsden Hospital FT, Sutton, Surrey, UK.

Testicular germ cell tumours are the commonest tumours of young men and are broadly managed either as pure seminomas or as 'nonseminomas'. The management of Stage 1 nonseminomatous germ cell tumours (NSGCTs), beyond surgical removal of the primary tumour at orchidectomy, is somewhat controversial. Cancer-specific survival rates in these patients are in the order of 99% regardless of whether surveillance, retroperitoneal lymph node dissection, or adjuvant chemotherapy is employed. Read More

Decision analysis defining optimal management of clinical stage 1 high-risk nonseminomatous germ cell testicular cancer with lymphovascular invasion.

Urol Oncol 2018 Jul 10;36(7):342.e1-342.e6. Epub 2018 May 10.

Department of Urologic Surgery, Vanderbilt University Medical Center, Nashville, TN.

Background: Risk of recurrent disease for men with clinical stage 1 high-risk nonseminomatous germ cell testicular cancer (CS1 NSGCT) with lymphovascular invasion (LVI) after orchiectomy is 50% and current treatment options (surveillance [S], retroperitoneal lymph node dissection [RPLND], or 1 cycle of BEP [BEP ×1]) are associated with a 99% disease specific survival, therefore practice patterns vary. We performed a decision analysis using updated data of long-term complications for men with CS1 NSGCT with LVI to quantify and assess relative treatment values.

Methods: Decision analysis included previously defined utilities (via standard gamble) for posttreatment states of living from 0 (death from disease) to 1 (alive in perfect health) and updated morbidity probabilities. Read More

Adolescent and Young Adult Testicular Germ Cell Tumors: Special Considerations.

Adv Urol 2018 31;2018:2375176. Epub 2018 Jan 31.

Department of Surgery, Division of Urology, University of Colorado School of Medicine and Children's Hospital Colorado, Aurora, CO, USA.

While testicular germ cell tumors (T-GCTs) make up only 0.5% of pediatric malignancies and less than 2% of adult malignancies, they comprise 14% of adolescent malignancies, making it the most common solid tumor in this age group. The transition in incidence at this age is also accompanied by a transition in tumor histology with adolescents having mostly pure embryonal carcinoma and mixed nonseminomatous germ cell tumors.

Orthoxenografts of Testicular Germ Cell Tumors Demonstrate Genomic Changes Associated with Cisplatin Resistance and Identify PDMP as a Resensitizing Agent.

Clin Cancer Res 2018 Aug 4;24(15):3755-3766. Epub 2018 Apr 4.

Program Against Cancer Therapeutic Resistance (ProCURE), Catalan Institute of Oncology (ICO), Bellvitge Institute for Biomedical Research (IDIBELL), Oncobell Program, L'Hospitalet del Llobregat, Barcelona, Catalonia, Spain.

To investigate the genetic basis of cisplatin resistance as efficacy of cisplatin-based chemotherapy in the treatment of distinct malignancies is often hampered by intrinsic or acquired drug resistance of tumor cells. We produced 14 orthoxenograft transplanting human nonseminomatous testicular germ cell tumors (TGCT) in mice, keeping the primary tumor features in terms of genotype, phenotype, and sensitivity to cisplatin. Chromosomal and genetic alterations were evaluated in matched cisplatin-sensitive and their counterpart orthoxenografts that developed resistance to cisplatin in nude mice. Read More

University of Southern California Institute of Urology, 1441 Eastlake Avenue, Los Angeles, CA 90033, USA.

Reducing the long-term morbidity in testicular cancer survivors represents a major area of interest. External beam radiation therapy and systemic chemotherapy are established treatments for seminoma; however, they are associated with late toxicities such as cardiovascular disease, insulin resistance, and secondary malignancy. Retroperitoneal lymph node dissection (RPLND) is a standard treatment for nonseminomatous germ cell tumors (NSGCT) that has minimal long-term morbidity. Read More

Detailed pathologic analysis on the co-occurrence of non-seminomatous germ cell tumor subtypes in matched orchiectomy and retroperitoneal lymph node dissections.

Med Oncol 2018 Jan 31;35(3):21. Epub 2018 Jan 31.

Department of Pathology, University of Michigan Health System, Ann Arbor, MI, USA.

The frequency of co-occurrence between germ cell tumor (GCT) components in non-seminomatous germ cell tumor (NSGCT) orchiectomy specimens and their correlation with histologic findings in subsequent retroperitoneal lymph node dissection (RPLND) specimens have not been well characterized. The objective of the study was to report the first detailed clinicopathologic analysis of NSGCT orchiectomy and RPLND samples to determine the likelihood and agreement of the co-occurrence of GCT components. A total of 118 consecutive patients with NSGCT treated between 1988 and 2012 who underwent both orchiectomy and RPLND at a single academic tertiary care center were analyzed. Read More

The Significance of Spermatic Cord Involvement by Testicular Germ Cell Tumors: Should We Be Staging Discontinuous Invasion From Involved Lymphovascular Spaces Differently From Direct Extension?

Am J Surg Pathol 2018 03;42(3):306-311

Departments of Pathology and Laboratory Medicine.

The recent 8th edition of the American Joint Committee on Cancer (AJCC) staging manual had multiple changes concerning how pathologists should stage germ cell tumors (GCTs) of the testis. A significant one concerns the impact of different types of spermatic cord involvement, specifically direct tumor extension versus discontinuous involvement by invasion through lymphovascular spaces. We compared clinicopathologic findings and outcome data between 2 cohorts with these findings to evaluate the validity of the change in the AJCC 8th edition manual. Read More

Global DNA methylation analysis reveals miR-214-3p contributes to cisplatin resistance in pediatric intracranial nongerminomatous malignant germ cell tumors.

Neuro Oncol 2018 03;20(4):519-530

Comprehensive Cancer Center of Taipei Medical University, Taipei Medical University, Taipei, Taiwan.

Background: Pediatric central nervous system germ cell tumors (CNSGCTs) are rare and heterogeneous neoplasms, which can be divided into germinomas and nongerminomatous germ cell tumors (NGGCTs). NGGCTs are further subdivided into mature teratomas and nongerminomatous malignant GCTs (NGMGCTs). Clinical outcomes suggest that NGMGCTs have poor prognosis and survival and that they require more extensive radiotherapy and adjuvant chemotherapy. Read More

Retroperitoneal lymph node dissection for testicular seminomas: population-based practice and survival outcomes.

World J Urol 2018 Jan 12;36(1):73-78. Epub 2017 Oct 12.

The James Buchanan Brady Urological Institute and Department of Urology, Johns Hopkins University School of Medicine, 600 N. Wolfe Street/Marburg 134, Baltimore, MD, 21287, USA.

Purpose: While retroperitoneal lymph node dissection (RPLND) is traditionally reserved for nonseminomatous germ cell tumors, recent efforts to reduce long-term toxicities of radiation and chemotherapy have turned attention to its application for testicular seminomas. Currently, RPLND is reserved for the post-chemotherapy for stage II testicular seminomas; we aimed to describe current utilization of RPNLD for testicular seminomas by stage and implications for survival.

Methods: A national sample of men diagnosed with stage IA/IB/IS/IIA/IIB/IIC testicular seminoma (1988-2013) was evaluated from SEER Program registries. Read More

Human Chorionic Gonadotropin Assays for Testicular Tumors: Closing the Gap between Clinical and Laboratory Practice.

Clin Chem 2018 Feb 11;64(2):270-278. Epub 2017 Oct 11.

Department of Biomedical and Clinical Sciences "Luigi Sacco," University of Milan, and Clinical Pathology Laboratory, ASST Fatebenefratelli-Sacco, Milan, Italy.

Background: Clinical practice guidelines recommend the measurement of human chorionic gonadotropin (hCG) and/or hCGβ in serum for management of testicular germ cell tumors (GCTs). These guidelines, however, disregard relevant biochemical information on hCG variants to be detected for oncological application. We set out to provide a critical review of the clinical evidence together with a characterization of the selectivity of currently marketed hCG immunoassays, identifying assays suitable for management of GCTs.
