Pulmonary Function Test

This phase II trial tests how well pembrolizumab in addition to chemotherapy (gemcitabine, brentuximab vedotin, and dacarbazine) works in treating frail patients with newly diagnosed Hodgkin lymphoma who aren't candidates for standard anthracycline-based treatment. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of cancer cells to grow and spread. Gemcitabine is a chemotherapy drug that blocks the cells from making deoxyribonucleic acid (DNA) and may kill cancer cells. Brentuximab vedotin is in a class of medications called antibody-drug conjugates. It is made of a monoclonal antibody called brentuximab that is linked to a cytotoxic agent called vedotin. Brentuximab attaches to CD30 positive lymphoma cells in a targeted way and delivers vedotin to kill them. Dacarbazine is in a class of medications called alkylating agents. It works by damaging the cell's DNA and may kill cancer cells and slow down or stop cancer growth. Pembrolizumab in combination chemotherapy may be a safe and effective alternative treatment option for frail patients with Hodgkin lymphoma who can't receive standard anthracycline-based treatment.

This phase III trial studies how well active surveillance help doctors to monitor subjects with low risk germ cell tumors for recurrence after their tumor is removed. When the germ cell tumor has spread outside of the organ in which it developed, it is considered metastatic. Chemotherapy drugs, such as bleomycin, carboplatin, etoposide, and cisplatin, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. The trial studies whether carboplatin or cisplatin is the preferred chemotherapy to use in treating metastatic standard risk germ cell tumors.
