Germ cell tumor

A germ-cell tumor is a neoplasm derived from germ cells. Germ-cell tumors can be cancerous or benign. Germ cells normally occur inside the gonads. GCTs that originate outside the gonads may be birth defects resulting from errors during development of the embryo Embryonal carcinoma has cancer cells that usually mix with another type of germ cell tumor. For example, embryonal carcinoma cells could mix with a teratoma and make it cancer Germ cell tumors are growths that form from reproductive cells. Tumors may be cancerous or noncancerous. Most germ cell tumors that are cancerous occur as cancer of the testicles (testicular cancer) or cancer of the ovaries (ovarian cancer) Surgery is the most common treatment of ovarian germ cell tumor. Types of surgery include hysterectomy and removal of one or both ovaries and fallopian tubes (bilateral salpingo-oophorectomy). Treatment may also include chemotherapy or radiation therapy. Learn about treatment options for ovarian germ cell tumors Germ cell tumors arise in the ovaries (in girls), the testes (in boys), and in several other locations, including the lower back (common in infancy), the abdomen, the chest, and within the brain. Germ cell tumors starting within the brain are discussed further under Brain Tumors

Germ cell tumors can spread (metastasize) to other parts of the body. The most common sites for metastasis are the lungs, liver, lymph nodes, and central nervous system. Rarely, germ cell tumors can spread to the bone, bone marrow, and other organs Germ cell tumors make up about 20 to 25 percent of all abnormal tissue masses in the ovaries. Only five percent of ovarian cancers are germ cell tumors. The most common benign forms are benign teratomas or dermoids. Cancerous forms include dysgerminomas, yolk sac tumors, mixed germ cell tumors, and non-gestational choriocarcinomas Germ cell tumours develop in germ cells. These are the cells in the body that develop into sperm and eggs. Germ cell tumours most often develop in the ovary or testicle because this is where most germ cells are Extragonadal germ cell tumors treatment depends on the type and can include surgery, chemotherapy, radiation therapy, and stem cell transplant. Learn more about the diagnosis and treatment of extragonadal germ cell tumors in this expert-reviewed summary Testicles contain many specialized cells, including germ cells, which make sperm, and other specialized cells that make testosterone. Testicular cancer is a relatively rare disease. Each year, it affects about 8,500 men in the United States, many of them men between the ages of 15 and 35

Types of germ cell tumors. Germ cells may travel to the chest, abdomen, or brain. Germ cell tumors that form in the brain are called intracranial germ cell tumors. For information on a germ cell tumor in the brain, read about childhood central nervous system tumors. Extracranial germ cell tumors are found outside of the brain Through time, these cells can grow into germ cell tumors, also called gonadal germ cell tumors. Germ cell tumors may be cancerous (malignant) or noncancerous (benign). Although germ cells are usually in the reproductive organs, these cells can sometimes travel to other parts of the body and cause tumors, called extragonadal germ cell tumors Germ cell tumors include the germinoma, the teratoma, the more aggressive embryonal carcinoma and yolk sac (endodermal sinus) tumors and the choriocarcinoma. Mixed germ cell tumors also exist. Because all these tumors tend to spread via the cerebrospinal fluid, diagnosis includes a check of the entire brain and spinal cord Treating benign germ cell tumors. Women with benign (non-cancerous) germ cell tumors such as mature teratomas (dermoid cysts) are cured by removing the part of the ovary that has the tumor (ovarian cystectomy) or by removing the entire ovary

Ovarian germ cell tumor is a disease in which malignant (cancer) cells form in the germ (egg) cells of the ovary. Germ cell tumors begin in the reproductive cells (egg or sperm) of the body. Ovarian germ cell tumors usually occur in teenage girls or young women and most often affect just one ovary About Germ Cell Tumors. The term germ cell comes from the term geminate, which means giving life. In humans, germ cells produce specialized cells needed for reproduction: sperm cells in boys and egg cells in girls. Germ cell cancer is a rare tumor that affects children, teens, and adults Germ cells are the cells that make sperm and eggs. They are part of our reproductive system. If germ cells start to grow out of control, they can form germ cell tumors. Doctors do not know what causes this. Germ cell tumors can be cancerous (malignant) or not cancerous (benign). However, even benign.

Germ cell tumors are also defined by how they look under a microscope and/or the hormones they produce. Teratomas are usually benign, but some are malignant. Teratomas of the tail bone are the most common germ cell tumor found in children, and are about four times more common in girls than in boys Germ cell tumors of the brain are treated differently than germ cell tumors in other parts of the body. These germ cell tumors are treated through the Dana-Farber/Boston Children's Brain Tumor Center , a world-renowned destination for children with malignant and non-malignant brain and spinal cord tumors An ovarian germ cell tumor is growth in a woman's ovaries. Most aren't cancer. Instead, they are benign growths. Cancerous germ cell tumors are rare. They make up only 2% of all ovarian. Children with benign germ cell tumors will have surgery to remove the tumor. Those with malignant tumors will first go through a process called staging. Staging is a classification system that helps doctors figure out how far the cancer has progressed Germ cell tumors occur in children of all ages. They develop from the reproductive cells that produce eggs in the ovaries and sperm in the testicles. These are called gonadal tumors. In rare cases, the cells travel and form tumors, called extragonadal germ cell tumors, in other parts of the body -- such as the abdomen, chest, neck, and head

Germ cell tumors can cause a variety of symptoms in children based primarily on the size and location of the tumor. Keep in mind that the symptoms of a germ cell tumor may resemble other more common conditions or medical problems Germ cells tumors are malignant (cancerous) or non-malignant (benign, non-cancerous) tumors that are comprised mostly of germ cells. Germ cells are the cells that develop in the embryo (fetus, or unborn baby) and become the cells that make up the reproductive system in males and females Germ cell tumors also termed germinal tumors refer to various tumors emanating from the germ cells. In this type of tumor is crucial for the dignity, whether it occurs in men or women. Germ cell tumors in women are usually benign, with both benign and more common malignant forms occurring in men

Germ cell tumors can spread (metastasize) to other parts of the body. The most common sites for metastasis are the lungs, liver, lymph nodes and central nervous system. Rarely, germ cell tumors can spread to the bone, bone marrow and other organs Initial therapy of early stage testicular germ cell tumors (GCTs) is based upon histology and tumor extent. An overview of therapy for men with testicular GCTs is presented here. The clinical manifestations, diagnosis, and staging are presented separately, as are more detailed discussions of specific clinical scenarios Mixed germ cell tumors are made up of both malignant germ cell tumor and teratoma. They can form in the ovary, testicle, or other areas of the body. Childhood extracranial germ cell tumors are grouped as gonadal or extragonadal Germ cell tumors are malignant (cancerous) or nonmalignant (benign, noncancerous) tumors that are comprised mostly of germ cells. Germ cells are the cells that develop in the embryo (fetus, or unborn baby) and become the cells that make up the reproductive system in males and females

Germ cell tumors are found widely throughout the body, and encompass a wide range of individual tumors. This article does not deal with any specific body locations. For detailed discussion please refer the articles listed at the end of this page Testicular germ cell cancers can start as a non-invasive form of the disease called carcinoma in situ (CIS) or intratubular germ cell neoplasia. In testicular CIS, the cells look abnormal under the microscope, but they have not yet spread outside the walls of the seminiferous tubules (where sperm cells are formed)

  5. Germ Cell Tumors. Germ cells are the cells in a developing fetus that eventually produce sperm in males and eggs in females. These cells normally develop along what's called the midline of a fetus (usually where the stomach and other internal organs will lie) before finally settling into place in the reproductive organs

Germ cells got their name because they normally produce the specialized cells that give rise to new life: sperm and egg cells - those needed for human reproduction. Germ cell tumors can arise in young children, teens, and adults. Germ cell tumors are rare; only 2.4 children out of 1 million will develop a germ cell tumor each year Germ cell tumors that develop in the brain or spinal cord also may be called CNS (central nervous system) germ cell tumors. There are two main types of germ cell tumors of the brain - germinomas and non-germinomatous tumors; if they include aspects of both, they are called mixed germ cell tumors

Testicular germ cell tumors (TGCT) are the most common malignancy in young men. While most TGCT are potentially curable, approximately 5% of patients with TGCT may develop chemoresistance and die from the disease. This review article summarizes current knowledge in genetics underlying the development, progression and chemoresistance of TGCT Germ Cell Tumors Research. Through the Children's Oncology Group, a nationwide organization, patients at Riley at IU Health can participate in experimental studies that may provide new, more effective treatments for a wide variety of cancers Rarely, these cells travel to other parts of the body and grow into germ cell tumors. Germ cell tumors may be either cancerous (malignant) or non-cancerous (benign) and may occur in the chest, abdomen or brain. Germ cell tumors that form outside the testes or ovaries are known as extragonadal germ cell tumors Germ cell tumors develop from cells that normally produce eggs or sperm in the reproductive organs — the testicles in men and ovaries in women. Germ, meaning seed, refers to the role that germ cells play in producing egg and sperm cells A germ cell tumor of the brain arises from developing cells that form in the embryo.

Intracranial germ cell tumors represent 3-5% of primary central nervous system tumors in children, in 50-60% consist of germinomas. The authors present a case report of 6-year-old boy with a history of Langerhans cell histiocytosis with subsequent brain germinoma, clinically manifested by precocious pseudopuberty on the basis of chorionic. Germ cell tumors are comprised mostly of the cells that develop in the embryo that will make up the reproductive system in males and females. After development the tumor follows a midline path through the body descending into the pelvis of the female and the scrotum of the male Sometimes these cells can form tumors. Gonadal germ cell tumors form in the ovaries and testicles. When germ cells travel to places other than the sex organs, the cells can form extragonadal germ cell tumors. These tumors can occur in the brain (intracranial) and other parts of the body such as the chest or abdomen (extracranial germ cell tumors)

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 Germ cell tumors of the brain develop from germ cells — the cells that later become sperm in the testicles or eggs in the ovaries. During the fetal period, these cells may get trapped in the brain and develop into tumors Germ Cell Tumors (GCTs) are not tumors caused by germs. The name comes from the fact that these tumors occur in a germ cell, one that germinates life such as in the testes or ovaries in an organism that reproduces sexually. A germ cell is one that gives rise to a gamete

Ovarian germ cell tumors (OGCTs) comprise 20-25% of all ovarian cancers arising from germ cells of ovary. Mature teratoma (dermoid) is the only benign and commonest germ cell tumor. Only 3-5% germ cell tumors are malignant, dysgerminomas being the most common. These tumors occur in adolescents and reproductive age group Gonadal germ cell tumors are generally the most common type and constitute 90% of germ cell tumors. The mediastinum is the second most frequently affected area ahead of other extragonadal areas, which include the retroperitoneum, the sacrococcygeal area, and the central nervous system information concerning germ cell tumors of the testes is limited. However, more than 90% of testicular cancers develop in germ cells, so epidemiological data for testicular cancer is a close approximation. GLOBOCAN estimated the worldwide incidence of testicular cancer in 2012 to be 55,266 (ASR of 1.5 per 100,000) [26] Active Surveillance, Bleomycin, Carboplatin, Etoposide, or Cisplatin in Treating Pediatric and Adult Patients With Germ Cell Tumors The safety and scientific validity of this study is the responsibility of the study sponsor and investigators

Tumors may appear in the germ cells, or egg-producing cells, of the ovaries. Most of these tumors are benign. Cancerous germ cell tumors make up less than 2 percent of ovarian cancers. Teens and women in their 20s are more likely to have this type of ovarian cancer. Ovarian germ cell tumors are divided into the following subtypes Germ cell tumors (GCTs) in the central nervous system (CNS) affect children and adults, predominantly occurring in the first and second decade of life; the peak incidence is from 10-19 years of age

Gonadal tumors are located in the reproductive organs — the ovaries in girls and the testicles in boys. Ovarian — In girls, ovarian germ cell tumors can be difficult to detect and may grow to a large size before they produce symptoms. These tumors usually aren't detected until age 10 or later BEP: Bleomycin / Etoposide / Cisplatin in Germ Cell Tumours (5-day regimen) Indication: 1) First line therapy for Germ Cell Tumours (curative intent) 2) First line therapy for Ovarian Granulosa Cell Tumours (all intents) Regimen details: Etoposide 100mg/m2 IV D1-D5 .

This chapter provides a comprehensive review of germ cell tumors of the central nervous system, including pathogenesis, demographics, localization, clinical and radiographic features, pathology, genetics, treatment, and prognosis, as well as detailed descriptions of each of the histologic variants (germinoma, embryonal carcinoma, yolk sac tumor, choriocarcinoma, teratoma, immature teratoma. Extragonadal germ cell tumors are typically diagnosed at birth or during early childhood, although older children and teens can develop these tumors, usually in the mediastinum. Also at increased risk are children with rare genetic conditions, such as Klinefelter syndrome, when boys are born with an extra X chromosome Surgery alone can also cure some testicular and ovarian malignant germ cell tumors. For testicular germ cell tumors, successful surgery may make chemotherapy unnecessary. If the disease has not spread to the lymph nodes, and if the levels of tumor marker proteins decrease to normal after surgery, there may be no need for chemotherapy Testicular tumors most commonly occur in men between 20 and 35 years of age, and are the most common solid malignancy in this group. Most often, patients present with a painless nodule or swelling of the testis This article covers germ cell tumours, often abbreviated GCT, which classically arise in the gonads (ovary, testis).

Mediastinal germ cell tumours develop in germ cells. These are the cells in the body that develop into sperm and eggs. Germ cell tumours usually develop in the testicles or ovaries but can grow in other areas of the body, such as the mediastinum (pronounced media-sty-num). The mediastinum is the. Germ Cell Tumors is a Neoplasm which obtained from germ cells. It can be characterized into cancerous or non-cancerous cell. However germ cells are found in gonads i.e. in testis and ovary. The germ cells which are present outside the gonads are the birth defects during the development of embryo Approximately 5-6% of all testis tumors are non-germ cell tumors of the testis. Three types will be considered, namely, Leydig cell tumors, Sertoli cell tumors, and gonadoblastomas. 1. Leydig Cell Tumors. Epidemiology & Pathology Leydig cell tumors are the most common non-germ cell tumors of the testis and account for 1-3% of all testicular tumors
