BACKGROUND Proliferative potential of testicular tumor was assessed by immunohistochemistry using anti-proliferating cell nuclear antigen (PCNA) monoclonal antibody and silver staining of argyrophilic nucleolar organizer region (AgNOR), and the results were compared with clinical course. METHODS Fourty-five patients with testicular tumor and 10 normal testicles were investigated. All specimen...

OBJECTIVES Incidence rates for testicular cancer have risen over the last few decades. Findings of an association between the risk of testicular cancer and social factors are controversial. The association of testicular cancer and different indicators of social factors were examined in this study. DESIGN Case-control study. SETTING Population-based multicentre study in four German regions (...

 Background: The Primitive Extratesticular Seminoma is a very rare condition and represents 3% of germ cell tumors; it is an indeterminate origin disease, whose diagnosis is often complicated by a nonspecific and highly variable clinical finding. CASE PRESENTATION A caucasian 55 years old male, non-smoker, arrived to our centre with cough, severe respiratory distress and dysphagia, in a conte...

OBJECTIVE Over the past 30 years, great strides have been made in the treatment of disseminated testicular tumors. Despite the low number of patients and the rarity of studies concerning primary advanced seminoma, the efficacy of chemotherapy is clear, mainly 3-4-cisplatin-based chemotherapy. Aiming to contribute to the understanding and implementation of proper chemotherapeutic management in a...

BACKGROUND Testicular cancer is rare but is notable because it affects mainly young men. The incidence of this disease has been increasing in developed countries throughout the world for several decades. The authors examined trends in the incidence of testicular germ cell cancer in Ontario for the period 1964-1996 according to the 2 main histologic groups, seminoma and non-seminoma. METHODS D...

It is widely held that the somatic cell population that is responsible for sperm development and output (Sertoli cells) is terminally differentiated and unmodifiable in adults. It is postulated, with little evidence, that Sertoli cells are not terminally differentiated in some phenotypes of infertility and testicular cancer. This study sought to compare markers of Sertoli cell differentiation i...

The aim of this study was to detect risk factors for febrile neutropenia (FN) in patients with testicular germ cell tumors (TGCT). In this retrospective cohort study at the Medical University of Graz, we included 413 consecutive TGCT patients who received adjuvant or curative treatment with cisplatin-based chemotherapy. FN occurred in 70 (16.9%) of 413 patients. In univariable logistic regressi...

T susceptibility to malignancy of an undescended testis is well established. We report a 56-year old patient with giant intraabdominal seminoma of right undescended testis with no lymph node or distant metastasis, and normal left testis. The tumor was completely excised. The late presentation and size of the tumor were discussed. The patient is now 40 months postoperatively with no evidence of ...
