The Warburg Effect Is Associated With Tumor Aggressiveness in Testicular Germ Cell Tumors

In conclusion, this study brings new insights on the metabolic characteristics of TGCTs, showing alterations in the expression of proteins related with the Warburg effect, as well as associations of the hyper-glycolytic and acid-resistant phenotype with aggressive clinicopathological parameters.

CONCLUSIONS: A rigorous use of classifications is mandatory to define staging since initial diagnosis. Applying treatments based on these classifications leads to excellent survival rates (99 % in CSI, 85 % in CSII+). PMID: 31610870 [PubMed - in process]

ConclusionThis is the first case of robot-assisted laparoscopic retroperitoneal lymph node dissection with concomitant inferior vena cava thrombectomy and reconstruction for metastatic mixed testicular germ cell cancer published to date. This complicated surgical procedure was facilitated by the innovative usage of three-dimensional image reconstruction for defining the vena cava tumor thrombus, a robotic ultrasound probe for intraoperatively defining the vena cava tumor thrombus, and vena cavoscopy using a flexible ureteroscope.

Purpose of review Understanding the molecular basis underlying testicular germ cell tumors (TGCTs) may help improve patient outcomes, particularly for patients with poorer risk or chemoresistant disease. Here, we review the major contemporary advances in elucidating TGCT genetics by discussing patterns of TGCT inheritance, recent genomic and transcriptomic discoveries in TGCT, and the role of genetics in predicting therapeutic resistance and in guiding treatment. Recent findings In the absence of a major high-penetrance TGCT susceptibility gene, inheritance is likely driven by a complex polygenic model with considerab...

Testicular Germ Cell Tumor (GCT) is the most common solid tumor in men between the ages of 20-44. Men diagnosed with GCT have excellent survival rates due to advances in the multimodal treatment paradigm of chemotherapy, radiation therapy and surgery. When considering the adequate treatment, several variables should be investigated and known to select the proper procedure. Therefore, when considering Testicular Intra-Epithelial Neoplasia, organ-sparring treatment, such as radiotherapy or organ-sparring surgery should be considered, reaching a cure rate of 98%. However, when the case is of a seminoma or a non-seminoma, orch...

Authors: Alsdorf W, Seidel C, Bokemeyer C, Oing C Abstract INTRODUCTION: With the implementation of platinum-based chemotherapy, germ cell tumors (GCTs) became a model for a curable solid tumor, with survival rates of 95% in all patients with>80% survival in metastatic stages. Areas covered: Herein, the authors review the current standards of adjuvant chemotherapy for stage I GCTs as well as first-line and salvage treatments for metastatic disease. Novel approaches for refractory disease are also reviewed. Expert opinion: Active surveillance should be considered for all stage I patients and is the preferred appr...

Abstract Testicular tumors are the most common tumors in adolescent and young men and germ cell tumors (TGCTs) account for most of all testicular cancers. Increasing incidence of TGCTs among males provides strong motivation to understand its biological and genetic basis. Gains of chromosome arm 12p and aneuploidy are nearly universal in TGCTs, but TGCTs have low point mutation rate. It is thought that TGCTs develop from premalignant intratubular germ cell neoplasia that is believed to arise from the failure of normal maturation of gonocytes during fetal or postnatal development. Progression toward invasive TG...

AbstractPurpose of ReviewThe purpose of this review is to educate medical oncologists on the management of patients with residual germ cell tumors and the role of surgical resection after platinum-based chemotherapy.Recent FindingsPatients with non-seminomatous testicular cancer and residual enlarged retroperitoneal lymph nodes>  1 cm following induction chemotherapy with normal tumor markers should undergo a post-chemotherapy retroperitoneal lymph node dissection. All patients with primary mediastinal non-seminoma should undergo surgical resection of the mediastinal mass post-chemotherapy. These are complex...

CONCLUSIONS: Almost half of patients treated with BEP/EP chemotherapy in routine practice have some form of reduced chemotherapy delivery. Despite this, long-term survival in the general population is very high. Further studies are required to understand the extent to which dose delivery might influence outcomes.
