Carcinoma in situ of contralateral testis in patients with testicular germ cell cancer: study of 27 cases in 500 patients.
Carcinoma in situ in the contralateral testis was diagnosed in 27 of 500 patients (5.4%) with unilateral testicular germ cell cancer. Eight of the 27 patients received intensive chemotherapy for spread of their initial testicular cancer. Follow up biopsy studies did not detect changes of carcinoma in situ in any of these patients, and none developed a contralateral testicular tumour (observatio...
متن کاملTesticular carcinoma in situ in patients with extragonadal germ-cell tumours: the clinical role of pretreatment biopsy.
BACKGROUND The aim of this study was to determine the prevalence of testicular carcinoma in situ (CIS) in patients with a malignant extragonadal germ-cell tumour (EGGCT) and the incidence of metachronous invasive testicular cancer (TC) in relation to the pretreatment demonstration of CIS. PATIENTS AND METHODS Sixty-eight patients with EGGCT (53 retroperitoneal, 15 mediastinal) had pre-chemoth...
متن کاملScreening for carcinoma in situ of the contralateral testis in patients with germinal testicular cancer.
Two hundred and fifty biopsy specimens from the contralateral testis in patients with unilateral germinal testicular cancer were analysed by light microscopy for carcinoma-in-situ changes. Changes were found in 13 (5.2%) patients. One-third of patients with an atrophic contralateral testis (volume less than or equal to 12 ml) and one-fifth of patients with a history of cryptorchidism had change...

Background: Testicular Carcinoma in situ (CIS), also known as intratubular germ cell neoplasia (ITGCN), is a pre-invasive precursor of testicular germ cell tumours (TCGTs), i.e seminomas and non-seminomas -the commonest cancer type of male adolescents and young adults- which can be diagnosed using a surgical biopsy. Infertility is one of the condition known to predispose to TGCT, but based on s...
متن کاملGiant Testicular Mixed Germ Cell Tumor
Objective: We report a case that we believe to be the largest example of a testicular mixed germ cell tumor with a clearly defined histology pattern. Clinical Presentation and Interventions: A 21-year-old patient consulted a urologist concerning a giant testicular mass. At the time of presentation the tumor measured 29 ! 20 ! 16 cm, with a weight of 4,850 g. Serum ·-fetoprotein was over 15,000 ...
