Active clinical trials for "Neoplasms, Germ Cell and Embryonal"

RATIONALE: Studying samples of semen from cancer survivors in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer. PURPOSE: This phase I research study is looking at the presence of donor-derived DNA in semen samples form cancer survivors who underwent donor stem cell transplant.

RATIONALE: Drugs used in chemotherapy, such as etoposide, carboplatin, and bleomycin, 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. Giving chemotherapy drugs before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed. Giving combination chemotherapy after surgery may kill any tumor cells that remain. PURPOSE: This clinical trial is studying how well giving etoposide, carboplatin, and bleomycin works in treating young patients undergoing surgery for malignant germ cell tumors.

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining more than one drug may kill more tumor cells. It is not yet known which regimen of combination chemotherapy may be more effective for germ cell cancer. PURPOSE: This randomized phase II/III trial is studying two different regimens of combination chemotherapy and comparing how well they work in treating men with germ cell cancer.

Primary objective: to evaluate progression-free survival in patients with clinical stage II A/B seminomatous germ cell tumor undergoing primary retroperitoneal lymph node dissection (RPLND) without adjuvant treatment Secondary objectives: overall survival perioperative complications (Clavien-Dindo score) quality of life (EORTC QLQ C30, EORTC QLQ TC26) long term sequelae rate of retrograde ejaculation

The treatment of germ cell tumours is considered to be one of the major successes in the area of cytotoxic chemotherapy. Even in patients who relapse after first line therapy, a durable remission rate of between 25% and 60% has been seen using further chemotherapy. In 1999, researchers at St Bartholomew's Hospital developed the GAMEC protocol (combination chemotherapy with filgrastim, actinomycin D, methotrexate, etoposide, cisplatin). Results from this study showed that 50% of patients with relapsed testicular cancer could be cured using this treatment. When we reviewed the individual patients it was clear that older patients (>35yrs) or patients with a raised Lactate Dehydrogenase (a blood test that monitors cancer activity), did not do as well. In addition, patients whose original tumour started in their chest (mediastinal germ cell tumour) have tended to do badly if they relapse. We have been developing a study for patients who fulfil at least one of these criteria. The GAMIO study (filgrastim, actinomycin D, methotrexate, irinotecan, oxaliplatin) has recently closed due to problems with high levels of toxicity from the irinotecan. GAMMA is a new study that will use paclitaxel instead of irinotecan and oxaliplatin instead of cisplatin. We expect that this treatment with oxaliplatin will be less damaging to the kidneys than cisplatin. Both oxaliplatin and paclitaxel and oxaliplatin and irinotecan have similar activity in relapsed patients in the phase II setting. We hope to improve on our previous results with this substitution and see if this will lead to an improvement in the cure rate of relapsed germ cell tumours with poor prognosis and reduce the side effects compared to our standard treatment. In addition, we do not expect any hearing damage and the treatment requires a shorter hospital stay.

RATIONALE: Sometimes, after surgery, the tumor may not need additional treatment until it progresses. In this case, observation may be sufficient. 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. Giving combination chemotherapy after surgery may kill any remaining tumor cells. PURPOSE: This phase III trial is studying how well observation and/or combination chemotherapy works after surgery or biopsy in treating young patients with extracranial germ cell tumors.

The purpose of this research study is to determine if radiation using proton beam therapy will kill the germ cell tumor in the participant's central nervous system. This type of radiation has been used previously on many patients with different types of cancers. There are two types of external radiation treatments, proton beam and photon beam. In this study we will be examining the effects of proton beam radiation therapy. Studies have suggested that this kind of radiation can spare normal tissue more than photon radiation therapy. The physical characteristics of proton beam radiation let the doctor safely increase the amount of radiation delivered to the tumor. We believe that proton beam therapy will potentially reduce side effects that participants would normally experience with photon radiation therapy.

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. An autologous stem cell transplant may be able to replace blood-forming cells that were destroyed by chemotherapy. PURPOSE: This phase II trial is studying the side effects of giving high-dose chemotherapy together with stem cell transplant and to see how well it works in treating patients with metastatic germ cell tumors that have not responded to first-line therapy.

RATIONALE: Studying samples of blood in the laboratory from patients with cancer may help doctors learn more about nausea and vomiting caused by cancer treatment. PURPOSE: This laboratory study is looking at blood samples from patients with cancer who were treated on a clinical trial to control nausea and vomiting during donor stem cell transplant.

STUDY DESIGN: Prospective, non-randomised multicentre study with patients stratified according to risk groups INVESTIGATIONAL MEDICINAL PRODUCTS The IMPs on this trial are Carboplatin, Cisplatin, Ifosfamide and Etoposide (as approved by German competent authority). PRIMARY OBJECTIVES: Germinoma To maintain current high event-free survival (EFS) rates using a risk adapted approach In localised germinoma: to omit whole brain and spinal irradiation by using combined treatment with standard chemotherapy and ventricular irradiation (+/- boosts) In bifocal tumours (pineal + suprasellar): to treat as non-metastatic disease and to omit whole brain and spinal irradiation by using combined treatment with standard chemotherapy and ventricular irradiation (+/- boosts) In metastatic disease: to maintain current excellent EFS in metastatic germinoma with craniospinal irradiation Malignant non-germinoma To improve EFS: by dose escalation of chemotherapy in patients identified as high risk at diagnosis ( age < 6 years and/or AFP serum / CSF > 1000 ng/ml) by standardising the surgical approach for residual disease after treatment Teratoma To register patients and collect data regarding diagnostics, treatment and outcome in order to develop future treatment strategies SECONDARY OBJECTIVES: Germinoma To minimise long term effects of irradiation by sparing spinal and whole brain radiotherapy in non-metastatic disease Malignant non-germinoma In standard risk to maintain EFS with chemotherapy and local irradiation Teratoma To evaluate the influence of surgery and treatment on outcome to assist in the development of a fu-ture treatment strategy For all histological subtypes To improve accuracy of diagnosis and staging in all registered patients To standardise neurosurgical intervention For all patients requiring biopsy or resection according to protocol guidelines, to collect and to store tumour material, and CSF where possible, for use in future biological studies. ENDPOINTS / Criteria for evaluation: Main end point Event-free survival, defined as minimum time from the date of diagnosis to: Death from any cause Relapse Progressive disease on therapy Or second malignancy Secondary end points Overall survival, defined as time to death from any cause, measured from the date of diagnosis Short and long term toxicity.
