Filter by:The investigators report a case of a 39-year-old man who presented an anterior mediastinal cystic mature teratoma. Those kind of tumor contain elements derived from more than one of the three primary germ layers (ectoderm, mesoderm, endoderm), frequently arranged in a haphazard manner. They arise from totipotent cells and, therefore, are primarily found in gonads, and more rarely in primitive cells kidnapped in other parts of the body. The tissues are immature to well differentiated and foreign to the anatomic site. Mature teratomas are either cystic or solid, although the cystic presentation predominates in gonadal sites. Benign teratomas are the most common mediastinal germ cell tumor, accounting 70% of the mediastinal germ cell tumors in children and 60% of those in adults. Immature teratomas are potentially malignant tumors; their prognosis is influenced by the anatomic site of the tumor, patient age, and the fraction of the tumor that is immature. Treatment of benign mediastinal teratoma includes complete surgical resection, with results in a excellent long-term cure rates. Complete resection of teratomas should be the goal of treatment.

F18-FDG is the widely used PET tracer in the routine practice of oncologic disease imaging using the technology of PET-CT. However, FDG-avidity is a characteristic of the individual tumor. There are various types of human malignancies, which are not taking FDG in access. In these cases FDG is not a sensitive tracer of imaging. In search for other tumor PET tracers, C11-Acetate has been shown recently in a few early studies to have a potential value in imaging of non-FDG-avid tumors. The purpose of the current study is to assess the role of 11C-acetate PET in various tumors, which often are not detected by 18F-FDG and were not widely assessed until now.
RATIONALE: Drugs used in chemotherapy, such as cisplatin, ifosfamide, and paclitaxel, 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. Colony-stimulating factors, such as pegfilgrastim, may increase the number of immune cells found in bone marrow or peripheral blood and may help the immune system recover from the side effects of chemotherapy. PURPOSE: This phase II trial is studying the side effects and how well giving combination chemotherapy together with pegfilgrastim works in treating patients with previously untreated germ cell tumors.
RATIONALE: Sunitinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth and by blocking blood flow to the tumor. PURPOSE: This phase II trial is studying how well sunitinib works in treating patients with metastatic germ cell tumors that have relapsed or not responded to treatment.
RATIONALE: Drugs used in chemotherapy, such as bleomycin, etoposide, and cisplatin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Colony-stimulating factors, such as pegfilgrastim, may increase the number of immune cells found in bone marrow or peripheral blood and may help the immune system recover from the side effects of chemotherapy. Giving combination chemotherapy together with pegfilgrastim may kill more tumor cells. PURPOSE: This phase II trial is studying the side effects and how well giving combination chemotherapy together with pegfilgrastim works in treating men with metastatic germ cell tumors.
RATIONALE: Germ cell tumors (GCT) are highly sensitive to chemotherapy such that even with metastatic disease at diagnosis, many patients can be cured. Patients who fall into the poor risk category or others who relapse can be successfully salvaged with high dose chemotherapy and autologous stem cell transplant (AuSCT). As in other diseases such as myeloma, sequential high dose chemotherapy and AuSCT may improve overall and disease free survival. PURPOSE: Because prior investigations in GCT suggest that a subset of high risk or relapsed patients may be cured with sequential cycles of high dose chemotherapy and AuSCT, we propose investigating how well non-cross resistant conditioning regimens work in treating patients with relapsed or high risk GCT.
RATIONALE: 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. An autologous peripheral stem cell transplant may be able to replace blood-forming cells that were destroyed by chemotherapy. This may allow more chemotherapy to be given so that more tumor cells are killed. PURPOSE: This phase I/II trial is studying the side effects and best dose of ifosfamide when given together with paclitaxel and carboplatin followed by an autologous stem cell transplant and to see how well they work in treating patients with germ cell tumors that did not respond to cisplatin.
RATIONALE: Drugs used in chemotherapy, such as cisplatin, vincristine, bleomycin, carboplatin, and etoposide phosphate, 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. It is not yet known which combination chemotherapy regimen is more effective in treating germ cell tumors. PURPOSE: This randomized phase II trial is studying two different combination chemotherapy regimens to compare how well they work in treating male patients with germ cell tumors.
RATIONALE: Drugs used in chemotherapy 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. PURPOSE: This randomized phase III trial is comparing two different combination chemotherapy regimens to see how well they work in treating patients with stage II or stage III non-seminomatous germ cell tumors.
