Mitotane (o,p'DDD) is established in the adjuvant and advanced-stage treatment of adrenocortical carcinoma and counteracts both tumor growth and tumor-related steroid production. Both the adrenal glands and the gonads are steroidogenically active organs and share a common embryogenic origin. Here, we describe the effects of mitotane in two patients with metastatic Leydig cell tumor (LCT) of the testes and associated severe androgen excess (serum testosterone 93 and 88 nmol/L, respectively; male reference range 7-27 nmol/L).

Objective: To explore whether response rates with a new intensive chemotherapy regimen, CBOP/BEP (carboplatin, bleomycin, vincristine, cisplatin/BEP), versus those in concurrent patients treated with standard BEP justify a phase 3 trial.
Design, Setting, And Participants: We conducted a phase 2 open-label randomised trial in patients with germ cell tumours of any extracranial primary site and one or more International Germ Cell Cancer Collaborative Group poor-prognosis features.
Serous tumours of the testis and paratestis are rare, with fewer than 50 cases reported in the literature. The majority of the reported cases have been borderline serous tumours, and these tend not to recur or metastasize. Conversely, serous carcinomas can metastasize but this is often a late event.

The existence of an array of potential new therapies is the result of a prodigious effort in the researching and defining of the molecular components of the cancer phenotype and the subsequent rational design of agents to target candidate pathways. A better understanding of the molecular biology of cancer may also aid in guiding the most appropriate use of existing therapies, such as conventional chemotherapy.

Until recently, the weight of evidence has supported the discontinuation of chemotherapy in advanced non-small-cell lung cancer (NSCLC) after 4-6 cycles of induction therapy. This allows patients with limited life expectancy a "treatment holiday." A minority of cases then go on to receive second-line therapy, although many deteriorate rapidly and never receive further active treatment.

All testicular germ cell tumors develop from the same precursor lesion, intratubular germ cell neoplasia unclassified, which in turn is thought to arise from malignant transformation of a primordial germ cell or gonocyte. These tumors are characterized by extreme chemosensitivity and are considered a model for curative disease.

The introduction of cisplatin-based combination chemotherapy in the late 1970s resulted in a dramatic improvement in the prognosis of patients with metastatic germ cell tumors, and overall cure rates in this group now exceed 80%. Randomized clinical trials and prognostic factors have guided treatment strategies over the last two decades.

In response to concerns that increased antibacterial prescribing selects for microbial resistance, we examined our data to explore the rationale for more limited prophylaxis.
View Article and Find Full Text PDFA rare case of a gastric presentation of a seminoma with burned out primary testicular tumor is described. The patient initially presented with upper gastrointestinal hemorrhage. Endoscopic biopsies were suggestive of seminoma, and testicular ultrasound revealed a focal lesion and testicular microcalcification.

Patients And Methods: Eight hundred seven patients with advanced HL (stage III to IV, or earlier stage with systemic symptoms or bulky disease) were randomly assigned between ABVD and MDR specified before randomization as alternating chlorambucil, vinblastine, procarbazine, and prednisolone (ChlVPP) with prednisolone, doxorubicin, bleomycin, vincristine, and etoposide (PABIOE), or hybrid ChlVPP/etoposide, vincristine, and doxorubicin (EVA). Radiotherapy was planned for incomplete response or initial bulk disease.
