INTRODUCTION: Testicular seminoma affects relatively young men with excellent survival outcomes. There has been increasing concern that radiotherapy (RT) leads to secondary malignant neoplasms (SMNs) and subsequent mortality. We evaluated the effect of RT on incidence of SMNs and quantified cancer-related mortality and other causes of death for patients with stage I and II testicular seminoma. MATERIAL AND METHODS: A national sample of men (1988-2013) diagnosed with stage IA/IB/IS/IIA/IIB/IIC testicular seminomas from Surveillance, Epidemiology, and End Results were evaluated...

Cryptorchidism is a very common anomaly, affecting 2-4% of male infants and is more common in premature infants. The long-term outcome despite orchidopexy still remains problematic and controversial with a risk of developing cancer 5-10 times greater than normal. Paratesticular tumors are mostly benign and very rare in children however malignant paratesticular tumors do arise, the most common being rhabdomyosarcoma. Primary paratesticular seminoma is extremely rare by itself and in most cases is associated with foci of seminoma within the testis...

The patient was a 25-year-old man. He was diagnosed as having a mediastinal tumor based on chest radiography. Chest computed tomography and magnetic resonance imaging revealed a cystic tumor in the anterior mediastinum. Total resection of the tumor with median sternotomy was performed. We anticipated that the tumor was a thymic cyst or teratoma, but pathological findings indicated a seminoma. The patient was discharged without any complication, and no recurrence of the lesion has been observed for 8 years after surgery without adjuvant therapy...

BACKGROUND: Controversy exists regarding the optimal management strategy for clinical stage IS seminomatous (SGCT) and nonseminomatous germ cell tumors (NSGCT) of the testis. OBJECTIVE: To assess contemporary treatment patterns and outcomes for clinical stage IS testicular cancer. DESIGN, SETTING, AND PARTICIPANTS: Using the National Cancer Data Base (2004-2012), we identified 1362 patients with clinical stage IS SGCT and NSGCT of the testis, treated with either adjuvant treatment (AT) or observation...

Anaplastic seminoma (AS) is an uncommon histological variant of classical seminoma of the testis and account for 5%-15% of cases. It is poorly described in the scientific literature. We present the case of a 50-years-old homeless man presenting with fever, marked left scrotal hardness and a fungating left scrotal lesion. He underwent left orchiopexy 40 years before. A computed tomography with contrast media showed a suspect testis cancer with scrotal involvment, extensive intralesional necrosis and multiple systemic metastases...

This study aimed to define the expression patterns of HENMT1 and PIWI proteins in human testis and investigate their association with transposon expression, infertility sub-type or development of testicular germ cell tumours (TGCT). Testis biopsies showing normal spermatogenesis were used to identify normal localization patterns of HENMT1 and PIWIL1 by immunolocalisation and RT-PCR after laser microdissection. 222 testis biopsies representing normal spermatogenesis, hypospermatogenesis, spermatogenic arrests, Sertoli cell-only (SCO) and testicular germ cell tumours (TGCT) were analysed by RT-qPCR for expression of HENMT1/PIWIL1/PIWIL2/PIWIL3/PIWIL4 and LINE-1...

BACKGROUND: Pure testicular seminoma does not express alpha fetoprotein (AFP). However, seminoma patients with mildly elevated serum AFP levels are increasingly reported. As this finding may prompt unwarranted treatment measures, we reviewed our experience with AFP levels in seminoma. PATIENTS AND METHODS: We retrospectively registered AFP levels in 254 consecutive seminoma patients, and in 196 male controls with non-malignant diseases. In those with elevated AFP levels, we re-examined the orchiectomy specimens histologically...

Extraskeletal osteosarcomas (OSs) are highly malignant soft tissue tumours associated with a poor prognosis. Only a few records of these rare aggressive neoplasms have been reported in the literature.We describe the case of a 49-year-old man, who presented to our tertiary care centre with a painful isolated lump around the umbilicus. After surgical biopsy, imaging and subsequent pathological analysis, the swelling was diagnosed to be a localised extraskeletal OS. He received previous radiation as treatment for testicular seminoma 40 years ago, which has been in remission ever since...

Burned-out tumor is a rare phenomenon in which a testicular tumor regresses in the primary lesion and progresses in a metastatic lesion. We report the case of a 30-year-old male with burned-out seminoma revealed by open biopsy of solitary 10th rib bone metastasis. He underwent inguinal orchiectomy, which revealed hyalinization, indicating a spontaneously regressed testicular tumor. Chemotherapy for seminoma was administered in three cycles of bleomycin + etoposide + cisplatin therapy. The chemotherapy was effective, and wide resection of the rib was subsequently performed...

OBJECTIVES: Primary mediastinal germ cell tumors (PMGCTs) are rare, which often makes them difficult to treat. Herein, we examined patients with PMGCTs who underwent multimodal treatment. METHODS: We examined 6 patients (median age: 25 years, range: 19-27 years) with PMGCTs who underwent multimodal treatment between April 2001 and March 2015. Three patients had seminomas, 2 patients had yolk sac tumors, and 1 patient had choriocarcinoma. The median observation period was 32...

PURPOSE: α-fetoprotein (AFP) and human chorionic gonadotropin subunit beta (B-HCG) are informative serum biomarkers for the primary diagnosis and follow-up of testicular germ cell cancer (TGCC) patients. About 20% of TGCC patients with a non-seminoma (NS) and about 80% with a seminoma (SE) are, however, negative for these biomarkers. Embryonic stem cell microRNAs (miRs) may serve as promising alternative serum biomarkers. Here we investigated a retrospective series of serum samples from selected TGCC patients who developed a relapse in time to test the possible additional value of the serum-based ampTSmiR test compared to the conventional serum-based protein biomarkers for follow-up...

We report the FDG PET/CT findings of seminoma in a 21-year-old woman with androgen insensitivity syndrome. PET images showed focal FDG uptake in the left pelvic sidewall, and a hypodense lesion with calcifications was noted in the corresponding CT images. Another smaller hypodense lesion with calcifications was noted in the right pelvic sidewall, but faint FDG uptake. Laparoscopic surgery was performed, and both lesions were pathologically confirmed as seminomas.

C-terminus kinesin motor KIFC1 is known for centrosome clustering in cancer cells with supernumerary centrosomes. KIFC1 crosslinks and glides on microtubules (MT) to assist normal bipolar spindle formation to avoid multi-polar cell division, which might be fatal. Testis cancer is the most common human cancer among young men. However, the gene expression profiles of testis cancer is still not complete and the expression of the C-terminus kinesin motor KIFC1 in testis cancer has not yet been examined. We found that KIFC1 is enriched in seminoma tissues in both mRNA level and protein level, and is specifically enriched in the cells that divide actively...

We present a rare cause of superior vena cava syndrome (SVC) in a previously healthy male aged 31 years. Malignancy was suspected due to unintentional weight loss and childhood exposure to radioactive fallout from a nuclear facility accident. A very large anterior mediastinal mass was identified and demonstrated to be an extragonadal seminoma. Extragonadal germ cell tumours are rare tumours with a high potential for cardiovascular, pulmonary and vascular sequelae. Studies have documented an increased risk of developing seminoma in patients with radioactive exposure...

INTRODUCTION: The Belgian Health Care Knowledge Centre (KCE) conducted a literature search leading to twelve quality indicators for testicular cancer. Data obtained from three nationwide databases, showed only five fully measurable quality indicators, one was partially measurable, and two could be determined using a proxy indicator. The four remaining indicators could not be assessed. In this study, we aimed to investigate if these quality indicators were registered and measurable in a medium-volume center...

INTRODUCTION: MicroRNA (miR)371a-3p was suggested to be a sensitive and specific new serum biomarker of germ cell tumours (GCTs); however, its clinical usefulness remains unproven. PATIENTS, METHODS: In 312 consecutive cases with various testicular diseases, serum levels of miR371a-3p were measured. Measurement results became available only after completion of treatment. Five patients with testicular seminoma were selected for review because of unanticipated clinical courses...

Testicular seminoma is the most common malignant tumor of the testis. It classically manifests as a painless mass. Radiologic evaluation with high-frequency ultrasonography (US) is critical for diagnosis. Seminomas are usually homogeneously hypoechoic masses at US. In challenging cases, magnetic resonance (MR) imaging may help confirm that a mass is intratesticular and provide data for local staging. Computed tomography (CT) provides valuable information for staging, including the presence and size of retroperitoneal lymph nodes...
