We describe the case of a 45-year-old male who was admitted with clinical signs of superior vena cava syndrome (SVCS). Physical examination showed collar of Stokes and extensive collateral circulation in the neck and anterosuperior thoracic region, as well as a large testicular mass. Fibrobronchoscopy revealed an endobronchial tumor, histopathologically diagnosed as seminoma, with the same characteristics as the testicular biopsy. Treatment was initiated with surgery, chemotherapy and radiotherapy, resulting in a major clinical improvement. We indicate the importance of considering SVCS as an entity related with less common neoplasms such as germ cell tumors. 相似文献

Our objective was to identify predictors of improved postthaw semen quality in men with testicular cancer banking sperm for fertility preservation. We reviewed 173 individual semen samples provided by 67 men with testicular germ cell tumor (TGCT) who cryopreserved sperm before gonadotoxic treatment between 1994 and 2010 at our tertiary university medical center. Our main outcomes measures were independent predictors for the greater postthaw total motile count (TMC) in men with TGCT. Men with NSGCT were more likely to be younger (P < 0.01) and had high cancer stage (II or III, P < 0.01) compared with men with seminoma. In our multiple regression model, NSGCT histology, use of density gradient purification, and fresh TMC > median fresh TMC each had increased odds of a postthaw TMC greater than median postthaw TMC. Interestingly, age, advanced cancer stage (II or III), rapid freezing protocol, and motility enhancer did not show increased odds of improved postthaw TMC in our models. In conclusion, men with TGCT or poor fresh TMC should consider preserving additional vials (at least 15 vials) before oncologic treatment. Density gradient purification should be routinely used to optimize postthaw TMC in men with TGCT. Larger, randomized studies evaluating cancer stage and various cryopreservation techniques are needed to assist in counseling men with TGCT regarding fertility preservation and optimizing cryosurvival. 相似文献

The mammalian target of rapamycin (TOR) has been implicated in the control of different stressors, growth factors, nutrients and hormones, participating in the control of key cellular functions. Controlling this many pathways poses mTOR signalling as a potential new target in new treatment strategies for multiple cancer types. mTOR components could potentially mislocated in tumour cells, which could lead to activation of signalling pathway that should not be active. Therefore, we aimed to show localisation of mTOR signal proteins in testicular seminoma. Tumoural testicular tissues were obtained from 10 patients with unilateral classic seminoma undergoing to therapeutic orchidectomy and compared with control human testicular tissues. Upon immunohistochemical evaluation, we detected mTOR and p‐mTOR (serine 2448), P70S6K, p‐P70S6K, PKCalpha and p‐PKCalpha, CD36 and MAPLC3 proteins in the cytoplasm of Sertoli cells in the seminiferous tubules. We also showed cytoplasmic perinuclear staining in seminoma cells. This study demonstrated the interaction of mTOR signalling pathway and testicular seminoma by showing intense cytoplasmic mTOR pathway proteins immunoreactivity in the seminoma, for the first time in humans. Therefore, we suggested that mTOR signalling components could create new clinical targets for treatment of testicular seminoma patients and male infertility in the future. 相似文献

The aim of this study is to report treatments results of patients with primary germ cell tumors (GCTs) of mediastinum.MethodsA retrospective review was done of 19 consecutive patients with mediastinal GCTs treated in “Institut de cancérologie de Lorraine” between 1990 and 2012.ResultsA total of 19 patients were enrolled in this study. Three patients had pure seminoma and 16 patients had non-seminomatous germ cell tumors. All patients were treated with cisplatinum based chemotherapy at a dose of 33.48 mg/m2/week. At the end of chemotherapy, three patients (15.8%) had complete response and negative marker, seven of them (36. 8%) had partial response and negative marker, five of them (26.32%) had partial response and positive marker, three of them (15.8%) had progressive disease (refractory disease) and one patient died because of the disease during treatment. The 1-year and 5-year overall survival rates were respectively 78 and 36% and the progression-free survival rate was 43 %. When relapse occurred, this happened within a 13 month period.ConclusionOur study confirmed the good management of mediastinal GCTs in our institute with similar results compared to literature. 相似文献

目的:报告1例罕见异位中肾管囊肿合并异位睾丸恶变病例,提高对本病的诊治水平。方法:回顾分析异位中肾管囊肿合并异位睾丸恶变的病例的临床资料,结合国内外相关文献,探讨异位中肾管囊肿合并异位睾丸恶变的发病机制、诊断及治疗。结果:经腹切除巨大囊肿及右侧异位恶变睾丸,左侧隐睾行下降固定,病理示"右异位中肾管囊肿,右侧异位睾丸精原细胞瘤",随访1年无转移。结论:异位中肾管囊肿合并异位睾丸恶变极为罕见,影像学检查可协助诊断,但最终需病理确诊,应早期行手术切除。后续治疗取决于隐睾恶变的病理类型及分期。 相似文献
