Germ cell tumor بالعربي

Germ cell tumors that occur in places other than the testicles and ovaries (extragonadal germ cell tumors) are very rare. Germ cell tumors tend to respond to treatment and many can be cured, even when diagnosed at a late stage About Germ Cell Tumors. Germ cell tumors are considered rare, accounting for approximately 4% of all cases of pediatric cancer. They can be benign or cancerous, and while both types can grow, only malignant tumors can spread to other organs Germ cell tumor ( GCT) is a neoplasm derived from germ cells. Germ-cell tumors can be cancerous or benign. Germ cells normally occur inside the gonads ( ovary and testis ). GCTs that originate outside the gonads may be birth defects resulting from errors during development of the embryo Mixed germ cell tumors are made up of at least two types of malignant germ cell tumor. They can form in the ovary, testicle, or other areas of the body. The cause of most childhood extracranial germ cell tumors is unknown. Having certain inherited disorders can increase the risk of extracranial germ cell tumors

Germ cell tumors - Symptoms and causes - Mayo Clini

Nonseminomatous germ cell tumors are cancer and are found in the brain. Yolk sac tumors , (also called endodermal sinus tumors) are usually cancer. They form in the testicles and ovaries Germ cell tumors represent neoplasms derived from germ cells. These cells are normally found in the ovaries or testes, in which their function is to produce eggs or sperm, respectively. These gonadal sites are the most common locations for the manifestation of germ cell tumors. Germ cell tumors are also found in extragonadal sites In 2016, the WHO classification of testicular germ cell tumors was revised considering advances in the understanding of their tumorigenesis and molecular features. This restructuring led to a division into two major groups with, on one hand, prepubertal-type tumors, not derived from germ cell neopla Germ cell tumors can manifest with unusual imaging characteristics suggestive of metastatic disease, autoimmune conditions, endocrine syndromes, and rare conditions such as fetus in fetu and ruptur...

Endodermal sinus tumor (yolk sac tumor). This is a germ cell tumor that is most often malignant, but may also be benign. This tumor most often affects the ovaries or testes, and the lower spine. They are often malignant and grow fast. Choriocarcinoma. This kind of tumor is very rare. It is often malignant. It starts from a layer of the placenta For germ cell tumor growth outside the gonads, they are termed as extracranial or extragonadal and usually begin in the sacrum and coccyx during early childhood. These are also often found in the lower chest for teenagers and young adults. In women, 30% of ovarian tumors originate from germ cells. Younger women, commonly patients under the age. CIS cells show similarities to embryonic germ cells, like their positivity for alkaline phosphatase, the stem cell factor receptor (c-KIT), and their glycogen content. These cells are frequently found in the adjacent parenchyma of an invasive seminoma and nonseminoma, of which a representative example is given in Figure 1

In men, germ cells are responsible for producing sperm. Most germ cell tumors in teenage boys and men start in one of the testicles. There are two different categories of germ cell tumors: seminoma and non-seminoma How common is a germ cell brain tumor? Germ cell brain tumors are very rare, accounting for less than 5 percent of all brain tumors in children. They are more common in boys than in girls. About half of germ cell brain tumors occur in children and young adults between the ages 11 and 30 Germ cell tumors are masses of tissue formed by immature cells that normally would have developed into mature eggs (in a female) or sperm (in a male). Ninety percent of germ cell tumors are gonadal, which means they begin in the reproductive cells of the testes (testicular tumors) or ovaries (ovarian tumors)

The association between non seminomatous germ cell tumors (GCTs) and hematological malignancies of rare lineage has been described in the literature. In some of these cases there is evidence that the leukemia derives from a pluripotent primitive clone present in the original germ cell tumor. We present a highly unusual case of a 23-year-old man of South Asian origin with a history of. The International Germ Cell Cancer Collaborative Group developed an accepted risk classification system in which patients are assigned to good-risk, intermediate-risk, and poor-risk categories based on histology, pretreatment tumor marker levels, site of primary tumor, and site of visceral metastases The goal of treatment for CNS germ cell tumors is to eliminate or shrink the tumor to minimize the risk of cancerous growth and to relieve symptoms. Radiation therapy may be used to kill tumor cells or shrink the tumor. CNS germ cell tumors are highly sensitive to radiation, and in many cases, this is the only treatment needed

BACKGROUND AND PURPOSE: Suprasellar papillary craniopharyngiomas and germ cell tumors in adults share some clinical and imaging similarities but have different therapeutic strategies and outcomes. This study aimed to evaluate the pretreatment diagnosis of these 2 tumors to improve the therapeutic outcome. MATERIALS AND METHODS: We retrospectively enrolled 18 adults with papillary. When cells that are meant to form sperm or eggs travel to other parts of the body instead, they can form tumors outside the gonads. That's why they are often called extragonadal germ cell tumors. They usually begin in the lungs, the lower back, the back of the abdomen, or the middle of the brain, near the pea-sized pineal gland. Extragonadal.

Tumors found in infants younger than 6 months old are more likely to be benign than those affecting older children. These tumors may cause difficulty passing urine or having a bowel movement and in older children may. Mixed germ cell tumor is composed of at least 2 different germ cell tumor histologic types and comprises approximately one-third of all testicular GCTs. 15 The tumor shows a variegated appearance, and the appearance reflects the tumor composition. There may be cystic, solid, soft, firm, hemorrhagic, and necrotic areas The most common germ cell tumors include: Teratomas. These tumors are benign, but can become malignant. Teratomas are the most common type of germ cell tumor to develop in the ovary and in extragonadal (not in the ovary or testes) locations. Teratomas usually can only be treated with surgery. Germinomas

An ovarian germ cell tumor is a growth in a woman's ovaries.Most of these tumors aren't cancer.Instead, they are benign growths. Cancerous germ cell tumors are rare Tumor Types. The vast majority of testicular tumors are GCTs (95%). GCTs originate from spermatogenic cells. GCTs are believed to originate from tissue stem cells and arise from the germinal epithelium of the seminiferous tubules owing to atypical cell proliferation known as testicular intratubular germ cell neoplasia unclassified (ITGCNU). 5, 29, 30 It is believed that the ITGCNU cells.

Drugs used in chemotherapy, such as paclitaxel, ifosfamide, and carboplatin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving more than one drug (combination chemotherapy) may kill more tumor cells Germ cells form as a baby grows in the womb. The cells usually form the eggs (ova) in females and the sperm in males. Germ cell tumors are made up of these underdeveloped cells. The tumors may be cancer (malignant) or not cancer (benign)

Children who have a cancerous germ cell tumor are considered to be at one of these stages: Stage 1: Doctors were able to remove the whole tumor through surgery. Blood tests do not show any more tumor activity. Stage 2: After removing the tumor, doctors may see tumor cells in lab tests of tissue. Or blood tests may show high levels of tumor markers As the name indicates the germ cell brain tumors occur in the human brain from the germ cells.

Introduction. Testicular germ cell tumor (TGCT) is the most common cancer in white men aged 15-44 years of age. The incidence of TGCT has increased rapidly in recent decades particularly among individuals of European ancestry [].Although multiple hypotheses investigating the impact of environmental exposures on risk of TGCT have been proposed, few have been found to be robustly associated.

Median age at diagnosis of MGCT was 23 years (range - 15 to 36 y). In 92 % of cases the germ cell tumor was of non-seminomatous origin with 27% cases reporting teratoma and 40.7 % of cases reporting embryonal carcinoma. All the reported cases were stage III and had elevated tumor markers with significant elevation in serum AFP compared to beta-HCG Testicular germ cell tumors are among the most common solid neoplasms in young-adult males. Their overall good prognosis puts them on the top of most curable solid cancers, with survival rates above 85-90% [].Around 85% and 70-75% of stage I seminoma and non-seminoma patients, respectively, are cured with orchiectomy alone [2,3,4,5], meaning that a substantial amount of patients can be.

Abstract: Most women diagnosed with malignant ovarian germ cell tumors have curable disease and experience excellent survival with manageable treatment-associated morbidity, related both to tumor biology and improvements in treatment over the last 4 decades. Malignant ovarian germ cell tumors occur predominantly in girls, adolescents Germ cells present in a developing fetus are the precursors of sperm and eggs. These cells may also develop into germ cell tumors. Germ cell tumors are extremely rare in adults, representing only about 0.3 percent to 0.6 percent of primary adult brain tumors. The greatest number of cases is diagnosed between 10 and 14 years of age Germ cells are the reproductive cells in an unborn baby. In boys, the cells make sperm and in girls, they make eggs. Before they settle into the reproductive organs, germ cells develop along the baby's midline. This is the area where the stomach and other internal organs will lie. Germ cells that.

Jackson (1967) reported a Jamaican family in which grandmother, mother, and daughter developed ovarian cancer (); 2 tumors were known to have been dysgerminomas. Stettner et al. (1999) found previous reports of 6 families in which more than 1 woman had a malignant germ cell tumor, and presented an additional ovarian germ cell cancer family in which a mother, her daughter, and her niece were. OCT4 was phosphorylated at S236 in a cell cycle-dependent manner in a patient sample and GCT cell lines. The substitution of endogenous OCT4 by a mimic of phosphorylated OCT4 with a serine-to-aspartate mutation at S236 (S236D) resulted in tumor cell differentiation, growth retardation, and inhibition of tumor sphere formation The most common germ cell tumors include the following types: Teratomas - contain cells from the three germ layers: ectoderm, mesoderm and endoderm. Teratomas can be malignant or benign, depending on the maturity and other types of cells that may be involved. Teratomas are the most common germ cell tumor found in the ovaries
