The cells are generally packed into nodules, and have a loose, sheet-like arrangement that is commonly interrupted by interstitial oedema. Unlike classical seminoma, fibrous septation and lymphocytic infiltrates are not seen. Cells undergoing mitosis are common, as are cells undergoing apoptosis.[1] Intratubular growth of spermatocytic seminoma can be seen, however there is no intratubular germ cell neoplasia of unspecified type (IGCNU). The intratubular growth probably accounts for the appearance of separate tumour nodules within the testis. Immunostaining for most of the usual testicular germ cell tumour markers is negative (i.e. placental alkaline phosphatase (PLAP), vimentin, actin, desmin, alpha fetoprotein (AFP), OCT4, human chorionic gonadotropin (hCG), and carcinoembryonic antigen (CEA)). Rarely, spermatocytic seminomas may show sarcomatoid differentiation, most commonly as undifferentiated spindled cells intermingled within the typical-appearing spermatocytic seminoma cells. ...
The UK Medical Research Council conducted this trial of carboplatin chemotherapy in advanced seminoma to compare single agent carboplatin with a standard combination of etoposide with cisplatin. The use of single agent carboplatin was expected to be associated with reduced toxicity. A total of 130 patients with advanced seminoma were randomly assigned to treatment with either single agent carboplatin (C) at a dose of 400 mg/m(2)to be corrected for glomerular filtration rate outside the range 81-120 ml min(-1)and to be administered on day 1 of a 21 day cycle to a total of 4 cycles or to etoposide + platinum (EP). The trial was designed as an equivalence study aiming to exclude a reduction in the 3-year progression-free survival in patients allocated to carboplatin of between 10 and 15%, requiring initially a target accrual of 250 patients (90% power significance level 5% (one-sided)). The trial closed after 130 patients had been randomized following recommendation by an independent data ...
A group of 2,739 infertile men whose testes were biopsied during the investigation of infertility in the period from January 1955 to December 1992 have been reviewed. Unilateral intratubular germ cell neoplasia was seen in the testicular biopsies of 16 patients and was always associated with testicular atrophy (Johnsen score lower than 4). Germ cell tumors of the testis occurred in 50% of untreated patients within 6 years and the longest period of tumor-free follow-up was 10 years. A retrospective study was performed to evaluate the incidence of tumors in a subset of 1,639 infertile men biopsied between 1955 and 1982. Three of the patients, without intratubular germ cell neoplasia on the biopsy, were found to have developed a germ cell tumor. The incidence and management of intratubular germ cell neoplasia in infertile men is discussed.. ...

SEMINOMA. Seminoma accounts for approximately 50% of all GCT and most frequently appears in the fourth decade of life. The typical or classic form consists of sheets of large cells with abundant cytoplasm and round, hyperchromatic nuclei with prominent nucleoli. A lymphocytic infiltrate or granulomatous reaction with giant cells, or both, is frequently present. Trophoblastic giant cells capable of producing human chorionic gonadotropin (hCG) are present in 15% to 20% of tumors. The presence of syncytiotrophoblastic giant cells in an otherwise pure seminoma does not influence prognosis or treatment. Anaplastic seminoma is an older term used when three or more mitotic figures are seen per high-powered field, and it has no clinical or prognostic importance. Stage for stage, anaplastic seminoma is similar in response and prognosis to classic seminoma.. An atypical form of seminoma has been described with unusual immunohistochemical features. While the cells cytologically resemble classic seminoma, ...
It is important to understand that a few patients with Stage I seminoma already have small amounts of cancer that have spread into the lymph nodes and cannot be detected with any of the currently available tests. Undetectable areas of cancer are referred to as micrometastases. The presence of micrometastases causes cancer recurrence following treatment with surgery alone. An effective treatment is needed to cleanse the body of micrometastases in order to improve a patients duration of survival and potential for cure. The delivery of cancer treatment following local treatment with surgery is referred to as "adjuvant" therapy and may include chemotherapy or radiation therapy.. Following surgical orchiectomy (removal of the affected testicle), approximately 15% of patients with a Stage I seminoma will experience cancer recurrence if they are not treated with additional therapy. By administering relatively low doses of chemotherapy and/or radiation therapy to the retroperitoneal and inguinal lymph ...
We have previously reported on bilateral intra-arterial (IA) chemosurgery for bilateral retinoblastoma, or tandem therapy.1 While this allows both eyes to be treated during the same IA session, it also exposes the patient to twice the dose of chemotherapy (typically melphalan and topotecan). Even at the doses used for IA, the systemic levels of melphalan can be dose-limiting (melphalan may induce neutropenia at doses higher than 0.4 mg/kg). To obviate the need for melphalan dose restriction during tandem therapy, we report on the use of single agent carboplatin to the fellow eye. ...
The mean age of manifestation of symptoms is 40 years. In patients of nonseminomatous testicular tumors, this median age is around 30 to 35 years. Seminoma tumors can also arise in older men. In rare cases, it may also be found to develop in younger boys.. In general, Seminomas do not result in any signs and symptoms and are detected when men observe lumps in their testicles. Up to 90% of affected individuals manifest symptoms such as inflammation or other palpable abnormalities. In rare cases, sufferers may also experience pain.. Locationwise, the majority of Seminoma tumors are intratesticular. These develop in the germ cells in the testicles. These can arise in extragonadal regions along the midline of the human body. Typical extragonadal spots include the Central Nervous System (CNS) and the mediastinum.. Variations in behavior and medical outcome indicate that Seminomas in the mediastinal spots are biologically different from those in gonadal spots. In contrast, tumors that develop in the ...
The human testicular germ cell cancer, seminoma, is one of the most common cancers of young men, and increasing in prevalence globally. To better understand mechanisms that govern viability, proliferation, and migration in testicular cancers, we used the TCam-2 seminoma cell line to model seminoma responses to four major signalling pathways: TGFb, retinoic acid (RA), Hedgehog, and WNT. Transcript, immunohistochemical, and functional analyses show TCam-2 cells are responsive to activation/suppression of all four pathways, and highlighted potential crosstalk points in these cells. Activation of TGFb signalling by BMP4 supports TCam-2 viability in the absence of serum, and suppression of canonical WNT signalling at the intracellular level with either IWR-1 or CCT036477 leads to loss of viability (measured by propidium iodide incorporation) and decreased migration (wound healing assay). These pathways exhibit crosstalk in embryonic stem cells to reduce pluripotency network transcripts, and may also ...

Chromosomal imbalances associated with carcinoma in situ and associated testicular germ cell tumours of adolescents and adults. Carcinoma in situ (CIS) or intratubular germ cell neoplasia is generally considered the precursor lesion of adult testicular germ cell tumours (TGCT). The chromosomal imbalances associated with CIS and the corresponding seminoma (SE) or nonseminoma (NS) have been determined by comparative genomic hybridization (CGH) analysis of microdissected material from seven cases. Significantly, the CIS showed no gain of 12p material whereas in the invasive components of all cases gain of 12p was found, in 2 cases associated with amplification of the 12p11.2-12.1 region. Interphase fluorescence in situ analysis was consistent with this and provided evidence for the i(12p) or 12p11.2-12.1 amplification in the SE and NS but not in the corresponding CIS. This suggests a role for these changes in progression of CIS to invasive testicular cancer or progression of the invasive disease. ...

In our study, adolescent dairy product consumption (with the exception of yoghurts) and especially milk was a risk factor for testicular cancer, especially for seminoma. We found an increasing risk for seminoma with increasing milk fat intake and an even stronger association between galactose consumption and seminoma especially in the younger men ages 15 to 34 years. Although several epidemiologic studies indicate that risk factors for seminoma and nonseminoma may differ (13, 16, 24-29), it is unclear whether the specificity of the observed effects in our study (no association with nonseminoma risk) is causal or not because the subgroup of nonseminoma patients was small, resulting in imprecise effect estimates.. In their registry-based prevalence case-control study, Davies et al. (6) found that the RR per 1/4 pint of milk per day (i.e., ∼120 mL per day) at age 17 years was 1.39 (95% CI, 1.19-1.63). Using the approach of dietary assessment as Davies et al., we found a somewhat lower RR (per 1/4 ...
Treatment of The testicles are located inside the scrotum, a loose bag of skin underneath the penis. They produce male sex hormones and sperm cells for reproduction, Testicular cancer is the most common cancer in American males between the ages of 15 and 34. But denial and embarrassment about the testicles contribute to testicular cancer being one of the least mentioned cancers. The cause of testicular cancer is unknown, Testicular cancer is highly treatable when diagnosed early. Depending on the type and stage of testicular cancer, you may receive one of several treatments, or a combination.

Testicular cancer is a disease in which cancerous cells form in the tissues of one or both testicles. Germ cells within the testicles produce young sperm that travel through a network of tubes into the epididymis, a long coil, where the sperm are stored in order to mature. Almost all testicular cancers start in the germ cells. The two main types of tumors that form from testicular germ cell are seminomas and nonseminomas. Nonseminoma tumors tend to grow slower and more contained. Seminoma tumors typically grow more quickly and farther spread. The testicular form of cancer is most commonly found in men ages 20 to 35 years old. Continue reading to learn more about common risk factors, symptoms and treatment.. ...
Testicular cancer (TC) is the most frequent solid malignancy in young men aged between 15 and 40 years. The worldwide incidence is about 7.5 per 100,000 subjects, but the rates vary considerably between countries and ethnic groups. About 95% of all TCs are represented by testicular germ cell tumors (TGCTs), which include seminoma and non-seminoma histological types. It has been reported that about 18,000 European subjects over reproductive age develop a TGCT every year and its incidence is increasing in several countries over the past 50 years. Early diagnosis and modern treatment have resulted in over 95% survival rate and improved quality of life in testicular cancer survivors. However, the benefits of cancer treatments may hide some risks. In fact, possible side effects can be developed during the treatment itself or later from months to years after the completion of therapy, persisting during the whole life. Therefore, TGCT survivors frequently complain a number of healthy problems such as
4189 Testicular germ cell tumours (TGCT) are the most common malignancy in young men. There are two main morphological subtypes of TGCT: seminoma (SE), a monomorphic tumor similar to undifferentiated germ cells; and non-seminoma (NSE), with multiple cell lineages from all three embryonic layers as well as extra-embryonic tissues resembling abnormal embryonal development at different stages. Although many studies have been carried out, the development pathway of TGCT is still debatable and little is known of the genetic alterations associated with the unique morphological phenotype of NSE. Using 10K single nucleotide polymorphism (SNP) microarray analysis, we observed in the NSEs, including both primary tumours and cell lines, many large-scale homozygous SNP domains, each extending over large cytogenetic regions up to the full length of the chromosomes, appearing as homozygous chromosome regions (HCRs). In contrast, fewer similar HCRs were found in the SEs and the majority of them occurred in ...
MEDICAL ANIMATION TRANSCRIPT: If you are a man, you have a pair of egg-shaped glands called testicles, enclosed in your scrotum, which is a pouch that hangs behind your penis. Your testicles produce sperm cells and make the hormone testosterone. Inside each testicle are coiled tubes called seminiferous tubules, where your body creates immature sperm cells, also known as germ cells or spermatogonia. Through a series of stages, called spermatogenesis, spermatogonia develop into mature sperm. Testicular cancer is a disease of abnormal cell growth in one or both of your testicles. It usually begins in your germ cells, where genetic damage or changes, called mutations, cause the cells to grow uncontrollably. The cancerous germ cells clump together to form a tumor, which continues to grow. In most cases, these mutations occur in your germ cells and are called germ cell tumors. Doctors classify germ cell tumors as nonseminoma or seminoma, or based on the appearance of the cells under a microscope.

The most common solid tumor in males ages 20-39 is testicular cancer. Testicular cancer is highly curable with 5-year survival rates above 96%. Long-term effects of both the testicular cancer and its treatment are important in understanding survivorship in this population. Chemotherapy poses its own specific risks such as vascular toxicity, lung disease and renal dysfunction. Also important is the understanding of fertility after testicular cancer and even prior to a cancer diagnosis patients may face issues with sperm count and testosterone level abnormalities. It is also critical to be aware of the possibility of developing a second malignancy after testicular cancer with the contralateral testis being a high-risk occurrence..

Purpose: Mismatch repair (MMR) deficiency and microsatellite instability (MSI) are associated with cisplatin resistance in human germ cell tumors (GCTs). BRAF mutation (V600E) is found in MSI colorectal cancers. The role of RAS/RAF pathway mutations in GCT treatment response is unknown. Methods: Two patient cohorts were investigated: 100 control GCTs (50 seminomas and 50 non-seminomas), and 35 cisplatin-based chemotherapy resistant GCTs. MMR-proteins were analysed by immunohistochemistry, and eight microsatellite loci were examined for MSI. Tumors were assessed for specific BRAF and KRAS mutations. Results: Resistant tumors showed a higher incidence of MSI than controls: 26% versus 0% in \#8805;2 loci (p,0.0001). All resistant tumors were wild-type KRAS, and two controls (2%) contained a KRAS mutation. There was a significantly higher incidence of BRAF V600E mutation in resistant tumors compared to controls: 26% versus 1% (p,0.0001). BRAF mutations highly correlated with MSI (p=0.006), and MSI ...

The advances seen in the treatment of testicular cancer are among the great achievements in modern medicine. These advances were made possible by the collaborative efforts of cancer researchers around the world. Investigators have been able to address many questions regarding the treatment of patients with disease limited to the testis, those with metastasis to the retroperitoneum only, and those with advanced metastatic disease. Questions answered include the chemotherapeutic agents to be used and in what combinations, the proper intensity of treatment and appropriate dosing, the optimal number of cycles of chemotherapy according to validated risk stratification, appropriate surgical approaches that preserve sexual function, the treatment of relapsed disease, what supportive care measures to take, and survivorship issues following treatment of testicular cancer ...
ANSWER: Most testicular cancers start in the cells that make sperm. The 2 most common types of testicular cancer are: Seminomas. These tumors tend to grow and spread slower than most other testicular cancers.

Testicular cancer radiation therapy makes use of high intensity x-rays or various other kinds of radiation for destroying the cancer cells present in the testicles of men. Normally, testicular cancer radiation therapy is given to the patients who have already undergone surgery. This is done to prevent the recurrence of testicular cancer in them. Sometimes testicular cancer radiation therapy might also be given to patients who are suffering from recurrence testicular cancer. The kind of radiation used for treating testicular cancer is known as external beam radiation which is produced form machines containing beams of high energy. This high energy beam is normally aimed toward the lymph nodes present in the pelvic or abdominal region. Testicular cancer radiation therapy dosage and the number of sittings would greatly depend on the stage of the disease and kind of testicular cancer. Most often testicular cancer radiation therapy is given to patients in their advanced stages of cancer.. Patients ...
